DETAILED DESCRIPTION OF THE INVENTION

(Contents) Technical Field of the Invention Prior Art (FIGS. 22 and 23) Problems to be Solved by the Invention Means for Solving the Problems (FIG. 1) Embodiments of the Invention (FIGS. 2 to 21) ) The invention's effect

[0002]

The present invention relates to a wireless packet communication system for wirelessly transmitting packet data, a mobile station and a base station used in the wireless packet communication system, and a packet transfer method in the wireless packet communication system.

[0003]

2. Description of the Related Art FIG. 22 is a block diagram showing an example of a conventional radio packet communication system. A radio packet communication system 100 shown in FIG. 22 includes a base station 112 forming a radio communication zone within a predetermined range, and The mobile stations 111-1 to 111-n (n is a natural number) capable of performing wireless communication with the base station 112 in the wireless communication zone of the station 112 and a certain mobile station 111-k (k = 1 to n) And an incoming call control station 113 for receiving the packet data from a desired communication network 114 and terminating the packet data to a base station 112. In FIG. 22, the base station 112 and the incoming call control station 113 are connected by wire, and the incoming call control station 113 and the network 114 are connected by wire.

In the above-described wireless packet communication system 100 (hereinafter, sometimes simply referred to as “communication system 100”), packet data addressed to a certain mobile station 111-k on the network 114 (hereinafter, simply referred to as “packet”). ) Occurs, the packet is transmitted to the terminating control station 1
13 and the wireless communication zone where the destination mobile station 111-k exists from the incoming call control station 113 (location zone).
To the base station 112 forming

[0005] Upon receiving a packet from the terminating control station 113, the base station 112 transmits the packet to the corresponding mobile station 1
It is transmitted wirelessly (wireless packet) to 11-k. Hereinafter, the details of such a packet transfer procedure will be described with reference to FIG. 23, taking as an example a procedure proposed in Japanese Patent Application Laid-Open No. 9-65423.

[0009] In FIG. 23, hatched portions represent control channels, shaded portions represent packet channels (physical channels), and the horizontal axis represents time passage. The control channel is used for notifying the mobile station 111-k of a candidate (usable) packet channel, calling the mobile station 111-k, and the like, and is shown in FIG. As described above, transmission and reception are periodically performed at a predetermined period (control channel transmission period) 121. On the other hand, the packet channel is used to transfer wireless packets, and is configured to be able to continuously transmit and receive between the base station 112 and the mobile station 111-k. Any use from 111-k is possible.

First, as shown in FIG. 23, the base station 112 broadcasts the candidate packet channels 131-1 and 131-2 to the mobile stations 111-k by using the control channel. -K is thus the base station 11
It is assumed that the control channel transmitted from the control channel 2 in the control channel transmission cycle 121 is intermittently received and is in a standby state.

In this state, when a packet addressed to a certain mobile station 11-k is received from the network 114 by the terminating control station 112, the terminating control station 112
2-1 is transferred to the base station 112 (see reference numeral 132-1). Then, the base station 112 transmits a call signal 141 using a downlink packet channel (which may be a control channel), and a response signal 142 to the call signal is returned from the mobile station 111-k to which the packet is to be transmitted. At that time, the mobile station 11 is transmitted using the packet channel.
The packet is transferred to 1-k (see reference numeral 132-2).

That is, when the base station 112 receives a packet addressed to the mobile station 111-k, the communication system 100 checks the packet transfer by transmitting and receiving the call signal 141 and the response signal 142, and then switches the packet channel. By performing packet transfer using such a method, effective use of the control channel capacity and reduction of the delay time from transmission of the call signal 141 to packet transfer can be achieved.

[0010]

However, even in such a conventional wireless packet communication system 100 (packet transfer method), the base station 112 receives a response signal 142 to the call signal 141 from the mobile station 111-k and responds. Since the actual packet transfer is performed after the confirmation, the packet transfer delay also occurs due to the response confirmation.

Further, the collision with the response signal 142 from another mobile station 111-k causes the mobile station 111-k to be transmitted.
If the response signal 142 from the mobile station disappears (response confirmation fails), the base station 112 cannot perform packet transfer unless the call signal 141 and the response signal 142 are transmitted / received again, so that the mobile station The probability of non-delivery of packets addressed to 111-k increases, leading to a decrease in reliability and serviceability.

The present invention has been made in view of such a problem, and eliminates the need to confirm a response from a mobile station to a call from a base station to a mobile station. An object of the present invention is to provide a wireless packet communication system, a mobile station and a base station used in the wireless packet communication system, and a packet transfer method in the wireless packet communication system, which can significantly reduce the non-delivery probability.

[0013]

FIG. 1 is a block diagram showing the principle of the present invention. The wireless packet communication system 1 of the present invention shown in FIG. A plurality of base stations 3-1 to 3 forming 4-N
-N (N is a natural number) and the base station 3 in the wireless communication zone 4-i of these base stations 3-i (where i = 1 to N).
Mobile station 2 capable of performing wireless communication with i-mobile station 2
The packet data addressed to the mobile station 2 is received from a desired communication network 6 and the packet data (hereinafter, simply referred to as “packet”) arrives at a base station 3-i forming a wireless communication zone 4-i where the mobile station 2 is located. An incoming call control station 5 is provided.

According to the present invention, as shown in FIG. 1, the mobile station 2 includes a location registration request unit 21 for each zone change and a no-response packet reception control unit 22, and the base station 3-i It comprises a location registration requesting unit 31 for a call control station and a no-response confirmation call notification control unit 32 (claim 1). Here, in the mobile station 2 (Claims 1 and 9), the location registration request unit 21 for each zone shift transmits the radio communication zone 4-4 associated with its own movement while waiting for a packet.
Each time i is transferred, a location registration request is issued to the base station 3-i forming the transfer destination wireless communication zone 4-i. When receiving the notification of the arrival of the packet data from the base station 3-i in the state where the location registration request is made by the location registration request unit 21 for each transition, the reception of the packet data is controlled without responding to the notification of the arrival.

On the other hand, in the base station 3-i (claims 1 and 17), the location registration request unit 31 for the called control station receives a location registration request from the location registration request unit 21 for each zone change of the mobile station 2. The non-response confirmation incoming call control unit 32 requests the incoming call control station 5 to perform position registration for itself and the mobile station.
When the packet data is received from the incoming call control station 5 in a state where the location registration request by the mobile station 2 is made, the mobile station 2 notifies the mobile station 2 of the incoming call and then checks the packet from the mobile station 2 without confirming the response from the mobile station 2 to the incoming call notification. Mobile station 2
Is to be called.

In the wireless packet communication system 1 of the present invention configured as described above, first, the wireless communication zone 4-i of the mobile station 2 accompanying the movement of the mobile station 2 waiting for a packet.
The base station 3 which forms the wireless communication zone 4-i of the transfer destination by the zone transfer every time
A position registration request is made for -i. Then, the base station 3-i issues a position registration request for itself and the mobile station 2 to the terminating control station 5 by the location control requesting unit 31 for the terminating control station.

Thus, even if the mobile station 2 moves arbitrarily between the radio communication zones 4-i, the incoming call control station 5 always recognizes the radio communication zone 4-i where the mobile station 2 exists. Can be. In this state, when the base station 3-i receives the packet from the incoming call control station 5, the non-acknowledgment confirmation incoming call control unit 32 notifies the mobile station 2 of the incoming call of the packet. The received packet is made to arrive at the mobile station 2 without confirming the response from the station 2.

When the mobile station 2 receives the above-mentioned incoming call notification from the base station 3-i while waiting for a packet, the non-response packet receiving control unit 22 does not respond to the incoming call notification, and the base station 3-i To control the reception of packets from That is, in the present invention, each time the mobile station 2 shifts in the wireless communication zone 4-i due to its own movement while waiting for a packet, the mobile station 2 transmits to the base station 3-i forming the transfer destination wireless communication zone 4-i. Make a location registration request,
When receiving the packet data from the incoming call control station 5 while waiting for the packet, the base station 3-i notifies the mobile station 2 of the incoming call, and then does not check the response from the mobile station 2 to the incoming call notification. The packet data is transferred to the mobile station.

Thus, in the wireless packet communication system 1 of the present invention, a packet addressed to the mobile station 2 can be reliably transferred to the target mobile station 2 without confirming the response to the notification of the arrival of the packet. By the way, the wireless packet communication system 1 of the present invention is provided with a packet waiting channel for transmitting at least the packet channel information used for the notification of the arrival of the packet data from the base station 3-i to the mobile station 2, Base station 3-
i, the non-response confirmation reception control unit 32 is configured to be able to perform the reception notification of the packet data in the packet waiting mode at a predetermined period using the packet channel information of the packet waiting channel, and The packet reception control unit 22 intermittently receives packet channel information from the packet waiting channel at the predetermined cycle,
If the received packet channel information is a notification of the arrival of packet data, the reception control of the packet data may be performed.

Thus, if the mobile station 2 monitors (intermittently receives) even the packet channel information of the packet waiting channel, the mobile station 2 surely recognizes the notification of the arrival of the packet data and controls the reception of the packet data. (Claims 2, 10, 18). In this case, the base station 3
The -i non-response confirmation reception control unit 32 can perform the above-described packet data arrival notification and the arrival notification of communication data other than the packet data at a predetermined cycle using the packet channel information of the packet waiting channel. The non-response packet reception control unit 22 of the mobile station 2
May be configured to control the reception of the communication data when the received packet channel information is the notification of the arrival of the communication data.

Thus, the mobile station 2 can control the reception of communication data other than packets even during packet waiting (intermittent reception of packet channel information) (claims 3, 11, and 19). Further, the wireless packet communication system 1 of the present invention transmits the packet channel information used for the above-described notification of the arrival of the packet data to the base station 3-i.
And a paging channel for transmitting paging channel information used for notifying the arrival of communication data other than packet data from the base station 3-i to the mobile station 2. And the non-response confirmation incoming call control unit 32 of the base station 3-i.
Is configured to perform an incoming notification of packet data using packet channel information of a packet waiting channel, and to perform an incoming notification of communication data other than packet data at a predetermined cycle using the paging channel information of a paging channel. In addition, the non-response packet reception control unit 22 of the mobile station 2 intermittently receives each channel information from each of the above-mentioned channels at the above-mentioned predetermined period, and the packet channel information received from the packet waiting channel is a packet data arrival notification. When there is, the reception control of the packet data may be performed, and when the paging channel information received from the paging channel is the notification of the arrival of the communication data, the reception control of the communication data may be performed.

Thus, in this case, the notification of the arrival of the packet from the base station 3-i to the mobile station 2 and the notification of the arrival of the communication data other than the packet are respectively performed on the individual channels. It is possible to receive communication data other than packets waiting for a packet while utilizing the data (claims 4, 12, and 20). Here, in this case, the non-response confirmation incoming call control unit 32 of the base station 2 spreads and modulates the above-mentioned packet channel information and the paging channel information with different codes, and transmits the above-mentioned incoming call notifications. And the non-response packet reception control unit 22 of the mobile station 2 performs despread demodulation of each channel information from the base station 3-i with the above-mentioned different codes. It may be configured to be separated.

Thus, the base station 3-i can simultaneously transmit the respective channel information, and the mobile station 2 can simultaneously receive the respective channel information from the base station 3-i. Becomes possible (claim 5,
13, 21). Also, the zone registration request unit 21 for each zone shift of the mobile station 2 prevents the above-mentioned position registration request from being issued until the time until the next reception of the above-mentioned packet channel information becomes equal to or less than a predetermined time during packet waiting. It may be configured. This eliminates the need for the mobile station 2 to make a location registration request until a time when there may be a packet arrival notification by receiving packet channel information next time (claims 6 and 14).

Further, the no-response packet reception control unit 22 of the mobile station 2 is configured to be able to change the intermittent reception cycle in accordance with the user's request for packet communication quality, The confirmation incoming call control unit 32 may be configured to be able to change the above-mentioned predetermined cycle according to the above-mentioned packet communication quality request. As a result, in the wireless packet communication system 1, the intermittent reception cycle can be arbitrarily changed in consideration of the quality requirement of the user for packet communication (claims 7, 15, and 22).

In this case, the non-response confirmation incoming call control unit 32 of the base station 3-i changes the predetermined cycle in accordance with the presence or absence of the communication delay with the communication partner of the mobile station in addition to the above packet communication quality request. And the non-response packet reception control unit 22 of the mobile station 2 may be configured to change the intermittent reception cycle in accordance with the presence or absence of the communication delay. Accordingly, the base station 3-i can change the intermittent reception cycle in consideration of a communication delay between the mobile station 2 and a communication partner of the mobile station 2 (claims 8 and 1).
6, 23).

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram showing a configuration of a wireless packet communication system as one embodiment of the present invention. The system 1 shown in FIG. 2 also forms wireless communication zones 4-1 to 4-N of a predetermined range, respectively. (N is a natural number) and the wireless communication zone 4-i of these base stations 3-i (where i = 1 to N).
A mobile station 2 capable of performing wireless communication with the base station 3-i within
The packet data addressed to the mobile station 2 is received from a mobile network (desired communication network) 6 (hereinafter sometimes simply referred to as “network 6”), and the packet data (hereinafter simply referred to as “packet”) is received from the mobile station. 2 is provided with an incoming call control station 5 for receiving a call to a base station 3-i forming a wireless communication zone (located zone) 4-i.

In FIG. 2, reference numeral 7 denotes a paging (calling) area in which a plurality of base stations 3-i simultaneously call the mobile station 2 by a paging channel (calling channel) described later. In addition, the mobile station 2 communicates not only packet communication but also normal voice and data (communication data other than packet; hereinafter, referred to as “line call”), for example, by connecting a packet communication terminal to a mobile phone. (Call).

Then, the base station 3-i and the mobile station 2 (hereinafter, referred to as a mobile station 2)
For example, FIG.
As schematically shown in FIG. 1, a paging (calling) channel (PCH) 8, a packet waiting channel 9, an uplink /
Downlink common physical channel 10 and dedicated physical channel 11
Is provided. Here, the PCH 8 is basically a channel for transmitting paging channel information used for notification of incoming call of a circuit call from the base station 3-i to the mobile station 2, and has a wide area (paging area 7). Is to be sent to However, with regard to the notification of the arrival of the packet when the packet line is not connected (for example, at the time of requesting the start of packet communication), the base station 3-i does not know the exact position (the visited zone 4-i) of the mobile station 2. So this PC
H8.

Specifically, according to the example of the following reference (1), the base station 3-i transmits the PCH 8 to the layer 3 information (the mobile station number or the line Call type information indicating a call / packet call) 81,
By performing predetermined coding processing such as convolutional coding or interleaving processing, the layer 3 information 81 is converted into radio channel information (272 bits: MUI 1 to 4) 82 for the physical layer (layer 1). Information presence / absence code (PI) 8 indicating presence / absence of information in the wireless channel information 82
3, and the obtained information (group) (PCH information) 84 is plural (m group: m is a natural number) as shown in FIG.
By distributing and transmitting each minute slot, as shown in FIG.
5 is formed as a channel for repeatedly transmitting.

Reference (1): "Specifications of Air In
terface for 3G Mobile System Ver.0.5 ("ARIB: Assoc
The mobile station 2 sets which group of PCH information 84 of which superframe is to be received from the base station 3-i (reception cycle). First, the PCH information 84 is received and the presence or absence of the information is confirmed by referring to the above-mentioned information presence / absence code 83. If the information is present, it is recognized that it is an incoming call notification to itself, and the information is reversed in the reverse of the above. By performing processing (predetermined decoding processing such as deinterleaving processing or Viterbi decoding), the layer 3 information 81 is restored, and it is determined whether the incoming call notification is a line call or a packet call. Accordingly, line connection processing for line calls and packet calls is performed.

On the other hand, the above-mentioned packet waiting channel 9
Transmits packet channel information used for notification of the arrival of a packet (hereinafter sometimes referred to as a packet call) to the base station 3.
A channel for transmitting from the i to the mobile station 2, basically the paging channel 8 described above with reference to FIGS.
Has the same format as the PCH (PCH shown in FIG. 3).
It has packet channel information 94 (information presence / absence code 93) having the same format as the information 84).

However, this packet waiting channel 9
Is set in a packet waiting mode in which the next packet is not received for a predetermined time or more after packet communication has been performed between the base station 3-i and the mobile station 2 (when a packet line has been connected) (channel 8 described later). , 9 at the time of intermittent reception), it is used in the zone 4-i (hereinafter, sometimes simply referred to as “zone 4-i”) for each base station 3-i.

That is, in the present embodiment, the notification of the incoming call of the packet call in the packet waiting mode is performed through the packet waiting channel 9, and the notification of the incoming call of the line call in the packet waiting mode is performed through the paging channel 8. It is. In the following, channel information 84, 9 of channels 8 and 9 will be described.
4 is simply referred to as “transmission of channels 8 and 9;
Reception ".

In FIG. 11, the common physical channel 10 transmits and receives packets having a relatively small amount of data and control information [notification and confirmation of a packet waiting mode, mobile station 2
A plurality of mobile stations 2 can be used in common by a channel used for transmitting / receiving a location registration request, transmission / reception notification (including a line call)). The dedicated physical channel 11 is basically used when the base station 3-3 receives a line call.
The channel is individually assigned to each mobile station 2 from i. Even in the case of a packet call, if the amount of data of a packet to be transmitted / received is large (if it is equal to or more than a predetermined amount), it is also assigned for packet communication.

When focusing on the functions of the main parts of the base station 3-i, for example, as shown in FIG. 8, the antenna duplexer 33, the RF transmitter 34A, the modulator 35A, the RF
Receiving unit 34B, demodulating unit 35B, channel coding /
Decoding unit 36 (channel coding unit 36
A, channel decoding unit 36B) and CPU 37
The coding section 361A of the channel coding section 36A performs the above-described convolutional coding and the like, and the interleaving section 362A performs the above-described interleaving processing. Interleaving section 361B performs the above-described deinterleaving processing and decode section 362
At B, the above-mentioned Viterbi decoding and the like are performed.

However, in the present embodiment, a CDMA (code division multiple access) system using spread spectrum communication is employed for wireless communication between the mobile station 2 and the base station 3-i. The unit 35A performs quadrature modulation (primary modulation) on transmission data (including channel information 84 and 94) and then spreads (secondary modulation) with a predetermined code. The data is despread using the same code as that on the transmitting side, and then orthogonally detected and demodulated.

It is assumed that the base station 3-i has a plurality of necessary parts corresponding to the plurality of mobile stations 2 in the above-described configuration. And the above CPU
Reference numeral 37 denotes wireless communication with the mobile station 2 (CDMA communication), such as calling of the mobile station 2, connection of a line call / packet call with the mobile station 2, assignment of common / individual physical channels 10 and 11, and the like.
In the present embodiment, the mobile station 2 moves every time the mobile station 2 moves in the visited zone 4-i.
The mobile station 2 receives the location registration request transmitted from the mobile station 2 and notifies the reception control station 5 of the request.
-I is always notified to the incoming call control station 5.

On the other hand, focusing on the function of the main part, the mobile station 2 is configured as shown in FIG. 7, for example, and has a configuration substantially similar to that of the base station 7 as can be seen from FIG. . That is, the mobile station 2 includes the antenna duplexer 24, the RF transmitter 25A, the modulator 26A, the RF receiver 25B, and the demodulator 2.
6B, channel coding / decoding unit 27
(A channel coding unit 27A, a channel decoding unit 27B), an activation control unit 28, a CPU 29, and the like.

In the mobile station 2 as well, convolutional coding and the like are performed by the coding section 271A of the channel coding section 27A on the transmission data before modulation by the modulation section 26A, and the interleaving processing is performed by the interleaving section 272A. On the other hand, the received data (including the PCH information 84 and the paging channel information 94) demodulated by the demodulation unit 26B is subjected to the channel decoding unit 2
The 7B deinterleaving unit 271B performs deinterleaving processing, and the decoding unit 272B performs the above-described Viterbi decoding and the like.

The mobile station 2 also performs CDMA
According to the method, the modulation unit 26A orthogonally modulates (primary modulation) the transmission data processed (encoded) by the channel coding unit 27A, and then spreads it with a predetermined code (secondary modulation).
On the contrary, the demodulation unit 26B despreads the reception data before being processed (decoded) by the channel decoding unit 27B using the same code as the transmission side, and then performs quadrature detection and demodulates the data. Has become.

Then, the CPU 29 performs the connection of the line / packet call line and the assignment of the physical channels 10 and 11 in response to the incoming call notification from the base station 3-i.
In this embodiment, the processing necessary for the CDMA communication with i is centrally controlled. In the present embodiment, each time a transition of the zone 4-i due to its own movement is detected while waiting for a packet (or during communication). It also has a function of making a position registration request for its current position to the incoming call control station 5 via the base station 3-i.

Assume, for example, that the mobile station 2 moves from the wireless communication zone 4-1 of the base station 3-1 to the wireless communication zone 4-2 of the base station 3-2 as shown in FIG. Mobile device 2
Moves from the position in FIG. 9 to the position,
Since the signal level received from the base station 3-2 gradually becomes higher than the signal level received from the base station 3-1, the condition for the zone transfer from the base station 3-1 to the base station 3-2 must be satisfied. Notify the base station 3-1.

On the other hand, the base station 3-2 allocates the packet waiting channel 9 to the mobile station 2 and starts transmission, and the mobile station 2 moves from one position to another, and the packet from the base station 3-2. The reception of the standby channel 9 is started. At this time, the mobile device 2
Since -1 has changed to the visited zone 4-2, a location registration request is made to the base station 3-2, and the base station 3-1 stops transmission of the packet waiting channel 9 to the mobile station 2 and releases the allocation. . When the mobile station 2 is waiting for a call, the mobile station 2 receives the peripheral base station list (broadcast information) broadcast from the base station 3-2, and stores the list of the previous location registration in the base station 3 of the transfer destination. Only when there is no -2 (that is, when the calling area 7 is changed), a location registration request is made.

By the way, the CPU 29 of the mobile unit 2
When a next packet is not received for a predetermined time after receiving a packet once, the mode shifts to the above-described packet standby mode, and control for intermittently receiving the PCH 8 and the packet standby channel 9 at predetermined intervals is also performed.
Specifically, R is transmitted through the activation control unit 28 in the transmission cycle of the PCH 8 and the packet waiting channel 9 of the base station 3-i.
By activating the F receiving unit 25B and the demodulating unit 26B, each of the channels 8 and 9 is received and demodulated, and the information presence / absence codes (PI) 83 and 93 of the obtained demodulated data are converted to PI
The channel decoding unit 27B is started only when the PI determination unit 281 determines that “information is present” with reference to the determination unit 281. Thereby, the power consumption of the mobile station 2 is reduced.

In this embodiment, since the CDMA communication is performed between the base station 3-i and the mobile station 2 as described above, the base station 3-i uses the PCH 8
The information 84 and the packet channel information 94 of the packet waiting channel 9 are spread-modulated with different codes and transmitted, so that the notification of the arrival of the packet call and the notification of the arrival of the line call can be simultaneously performed through the respective channels 8 and 9. In the mobile station 2, even if each of the channel information 84 and 94 is received at the same time, they can be separated and identified by despread demodulation with different codes.

That is, the base station 3-i of the present embodiment performs spread spectrum modulation of the above-described packet channel information and paging channel information with different codes through the modulator 35A, respectively, by the non-acknowledgment confirmation incoming call controller 32 described later. The mobile station 2 can simultaneously perform the above-described incoming call notification through each of the channels 8 and 9.
2, each channel information from the base station 3-i is separated by performing spectrum despread demodulation with the above-described different code through the demodulation unit 26B.

Therefore, for example, as shown in FIG. 6, the notification of the arrival of a packet call is made in five groups for every two superframes (here, one superframe is made up of 256 groups from 0 to 255), and a line call is received. If the notification is performed in five groups for each superframe, the mobile station 2 does not need to intermittently receive the incoming call notification of the line call and the incoming call notification of the packet call at individual periods. Power consumption can be reduced.

Hereinafter, the operation of the wireless packet communication system 1 according to the present embodiment configured as described above will be described in detail. (1) Description of Basic Operation of Mobile Station 2 First, as shown in FIG. 13, the mobile station 2 (CPU 29)
When the power is turned on, it receives broadcast information (base station ID and the like) from the base station 3-i (step A1) and determines whether or not the calling area 7 has changed due to its own movement (step A1). A2). If the paging area 7 has changed (if determined to be YES in step A2), the mobile station 2 sends a location registration request via the uplink common physical channel 10 to the base station 3-i that has received the broadcast information. (Step A3). If the calling area 7 has not changed, no position registration request is made (NO route in step A2).

Next, the mobile device 2 determines (monitors) whether or not the serving zone 4-i has changed based on the zone transfer condition (steps A4 and A5). The monitoring of the transition of -i is continued (NO route in step A5), and if it has changed, the processing from step A1 is re-executed (YES route in step A5).

By the way, at this time, the mobile station 2
It is determined whether or not there is outgoing information addressed to -i (step A
At the same time, the call channel 8 is intermittently received (step A8). If there is transmission information addressed to the base station 3-i (YES in step A6), the mobile station 2 transmits the base station 3-i through the uplink common physical channel 10.
A call request is made to i (step A7). If there is no transmission information, the mobile device 2 continues to monitor whether there is transmission information (NO route in step A6).

On the other hand, when the call channel 8 is intermittently received, the mobile station 2 determines whether or not there is an incoming call notification by the PI determining unit 281 (step A9), and if there is an incoming call notification (YES in step A9). If determined), a response signal is returned to the base station 3-i through the uplink common physical channel 10 (step A10). Then, the mobile device 2 determines whether the outgoing call request or the incoming call notification is for a line call or a packet call (step A11).
If it is a line call, a line connection process for a line call is executed (step 12), and after detecting a transition condition of the visited zone 4-i (step A13), the individual physical channel 11
Is assigned (step A14), and communication is started (step A15).

Then, the mobile station 2 determines (monitors) whether or not the communication has been completed (step A16), and determines whether the transition condition of the visited zone 4-i is satisfied during the communication (the visited zone 4). -I) (Step A18). When the communication ends, the mobile device 2
A line disconnection process for a line call is executed (Y in step A16).
From the ES route, step A17), and if not completed, the communication is continued as it is (NO route of step A16).

Further, if the transfer of the zone 4-i occurs during communication (if YES is determined in step A 18), the mobile station 2 notifies the transfer from the base station 3-i of the transfer destination. The information is received (step A19), and a handover process for switching the communication partner to the transfer destination base station 3-i is executed (request to the base station 3-i) (step A20). In the present embodiment, the mobile station 2 can simultaneously receive signals from the source / destination base stations 3-i by the CDMA method at this time. i
When the reception level of the signal from
By stopping the reception of the signal from the transfer source base station 3-i, the above-described switching can be performed without interrupting the communication (called a soft handover process).

On the other hand, if the outgoing request or the incoming call notification is a packet call in step A11, the mobile station 2 executes a line connection process for the packet call (step A21), and the mobile station 2 establishes a connection in the zone 4-i. A transition condition is detected (step A22). If the packet flow (transmission amount) to be transmitted / received is large (a predetermined amount or more), the mobile device 2 performs packet communication through the dedicated physical channel 11 (from the YES route of step A23 to step A2).
4, A25), when the packet flow rate is small, packet communication is performed through the common physical channel 10 (from the NO route of step A23 to step A31). It should be noted that the dedicated physical channel 11 is used or the common physical channel 10 is used.
Is determined by the control information transmitted to the common physical channel 10 after the incoming call notification from the base station 3-i.

Next, the mobile station 2 sets the dedicated physical channel 11
It is determined whether or not the transition condition of the visited zone 4-i is satisfied during the packet communication through (i.e., whether or not the transition of the visited zone 4-i has occurred) (step A26). Visiting zone 4
If the transition of -i has occurred (YES in step A26), the mobile device 2 receives the broadcast information of the destination base station 3-i (step A27) and executes the soft handover process. (Step A28).

Thereafter, the mobile station 2 determines whether or not it has received a packet line disconnection request from the base station 3-i side (from the communication partner mobile station 2 via the network 6, the receiving control station 5, and the base station 3-i). Then, it is determined whether or not a line disconnection request (by the user of the mobile device 2) has occurred in itself (step A2).
9) If there is no line disconnection request, step A23
Is executed (NO route of step A29). On the other hand, if there is a line disconnection request, the mobile station 2 executes a disconnection process of a packet call line (hereinafter, also referred to as a packet line) (step A30), and a step A4.
Re-execute the subsequent processing.

By the way, even when the packet communication is being performed through the common physical channel 10, the mobile station 2 determines the location zone 4 based on the transition condition detected in step A22.
It is determined whether or not the transition of −i has occurred (step A3).
2) If the transfer of the zone 4-i has occurred, the broadcast information is received from the transfer destination base station 3-i (step A <b> 3).
3), execute a handover process (step A3)
4).

Then, the mobile station 2 determines whether or not the packet transmission / reception suspension time has exceeded the predetermined time t1 (step A35), and if it has not elapsed (step A35, NO is determined). B), the processing from step A29 is executed. On the other hand, if the packet transmission / reception suspension time has exceeded the predetermined time t1 (determined as YES in step A35), the mobile station 2 enters the packet waiting mode, and as shown in FIG. (I) while detecting the transition condition of -i (step A
36), determining whether there is transmission information (step A40),
In addition, each channel information of the call channel 8 and the packet waiting channel 9 is intermittently received, and it is determined whether there is an incoming call notification (steps A43, A44, A46, A).
47).

Then, the mobile device 2 determines whether or not the transfer of the serving zone 4-i has occurred based on the detected transfer condition of the serving zone 4-i (step A37). As a result, if the transfer of the visited zone 4-i has occurred, the mobile device 2
Receives the broadcast information from the transfer destination base station 3-i (step A38), makes a location registration request to the base station 3-i through the uplink common physical channel 10, (step A39), and thereafter. , The transition of the visited zone 4-i is continuously monitored. In addition, when the transfer of the visited zone 4-i has not occurred, the mobile device 2 continuously monitors the transfer of the visited zone 4-i (NO route of step A37).

In other words, the mobile station 2 (CPU 29) executes the above-described steps A36 to A39, so that the mobile station 2 (the CPU 29) moves to the zone 4 in accordance with its own movement while waiting for a packet.
It has a function as a zone transfer location registration request unit 21 (see FIG. 7) that issues a location registration request to the base station 3-i that forms the destination zone 4-i at the transfer of i. ing.

If there is transmission information in step A40, mobile station 2 issues a transmission request to base station 3-i through uplink common physical channel 10 (YES in step A40 to step A4).
1). At this time, the mobile device 2 determines whether the transmission request is for a line call or a packet call (step A42).
A line connection process for a line call is executed (step A48),
After detecting the transition condition of the visited zone 4-i and allocating the dedicated physical channel 11, (steps A49 and A5)
0), communication is started (step A51).

Then, the mobile station 2 monitors (determines) whether or not the communication has been completed (step A52). If the communication has not been completed, the communication is continued (NO route of step A52). A line disconnection process for the line call is executed (from the YES route of step A52 to step A5).
3) The processing after step A36 is executed again.

At this time, the mobile station 2 monitors whether or not the transition to the zone 4i occurs during communication based on the transition condition for the zone 4i detected in step A49. (Step A54), if the transition has not occurred, the monitoring is continued as it is (NO route of Step A54), and if the transition has occurred, the broadcast information from the destination base station 3-i is received (Step A54). (Step A55) from the YES route of step (A), and the handover process is executed (step A56).

Further, the mobile station 2 determines whether or not it has received a packet line disconnection request signal from the base station 3-i side, and whether or not the mobile station 2 itself has received a line disconnection request (by the user of the mobile station 2). Monitoring (step A57), and if no disconnection request signal is received, communication is continued (step A57).
If the disconnection request signal has been received, a packet line disconnection process is executed (step A58). At this time, if communication of the line call has already been performed, the mobile device 2 executes the processing after step A15 shown in FIG.

By the way, if there is an incoming call notification from the paging channel 8, the mobile station 2 transmits a response signal to the base station 3-i through the uplink common physical channel 10 (from the YES route of step A44 to step A4).
5) Execute line connection processing of the line call (step A4).
8) Thereafter, the communication control for the line call in steps A49 to A58 is executed.

On the other hand, when there is an incoming call notification from the packet waiting channel 9, the mobile station 2 detects the subsequent condition of the visited zone 4-i (step A59), and if the packet flow rate is large (not less than the predetermined amount). For example) (if YES is determined in step A60), the dedicated physical channel 11 is allocated (step A61) without returning a response signal to the above-described incoming call notification to the base station 3-i, and the dedicated physical channel 11 is allocated. Packet communication using (packet reception control)
[Step A62: Individual physical channel transmission / reception state 14 (see FIG. 10)].

Then, the mobile station 2 executes the above step A5
Based on the transfer condition detected in step 9, it is determined whether or not the transfer of the zone 4-i has occurred (step A63).
If the transfer of the serving zone 4-i has occurred, the notification information from the transfer destination base station 3-i is received (step A64),
A handover process is executed (step A65). If the transition has not occurred, the handover process is not executed (NO route in step A63).

Further, the mobile station 2 determines whether or not it has received a packet line disconnection request from the base station 3-i side, and whether or not the mobile station 2 itself has issued a line disconnection request (by the user of the mobile station 2). Monitoring is performed (step A66), and if a line disconnection request has not been received (NO in step A66), the processing after step A60 is executed, and if a disconnection request signal is received (YES in step A66) If it is, the packet line disconnection process is executed (step A67), and steps A4, A6, A8 shown in FIG.
Re-execute the subsequent processing.

On the other hand, if the packet flow for which the incoming call notification has been made is smaller than the predetermined amount (if NO is determined in step A60), the mobile station 2 performs communication using the common physical channel 10 (packet reception control). [Step A
68: Common physical channel transmission / reception state 13 (see FIG. 10)]. In this case, a response signal to the above-described incoming call notification is not returned to the base station 3-i.

Then, based on the transition condition detected in the above step A59, it is monitored whether or not a transition of the visited zone 4-i occurs during this communication (step A69), and the transition of the visited zone 4-i is performed. Occurs (Y at step A69).
If it is determined to be ES, the broadcast information from the transfer destination base station 3-i is received (step A70), and a handover process is executed (step A71). Zone 4
If the transfer of i has not occurred, the handover process is not executed (NO route in step A69).

Further, the mobile unit 2 again operates for a predetermined time t1.
It is monitored whether or not the packet transmission / reception stops (step A72). If the packet transmission / reception suspension time does not exceed the predetermined time t1, the process from step A66 is executed (step NO72 from step A72). A66) If the predetermined time t1 or more has elapsed, the packet standby mode is again set (the packet standby channel reception state 12 (see FIG. 10)), and the above-described step A3 is performed.
6, A40, A43, A46 and subsequent processes are executed.

That is, the mobile unit 2 (CPU 2
9) corresponds to steps A43, A44, A46, A4
7, A59 to A72, the zone-based location registration request unit 21 (FIG.
Base station 3-
When the notification of the arrival of the packet is received from i, it has a function as a no-response packet reception control unit 22 (see FIG. 7) that controls the reception of the packet without responding to the notification of the arrival of the packet.

In this embodiment, steps A43 to A45, A48 to A58, A46, A47, A
By executing steps 59 to A72, the non-response packet reception control unit 22 intermittently receives the respective channel information from the respective channels 8 and 9 at a predetermined cycle as described above with reference to FIG. If the information is the notification of the arrival of the packet, the reception control of the packet is performed,
If the paging channel information received from the paging channel 8 is an incoming call notification of a line call, the reception of the line call is controlled.

(2) Description of Basic Operation of Base Station 3-i Next, the basic operation of the base station 3-i (CPU 37) will be described with reference to the flowchart shown in FIG. First, the base station 3-i (CPU 37) determines whether or not it has received incoming information from the network 6 (the incoming call control station 5), whether it has received any signal (information) from the uplink common physical channel 10 from the mobile station 2, or It monitors whether a packet line disconnection request signal has been received from the control station 5 (step B1).
For example, when receiving incoming information from the incoming call control station 5 (determined as YES in step B1), it is determined whether or not the packet line is already connected (step B4).

As a result, if the packet line is not connected, the base station 3-i sends a call notification (call notification) to the target mobile station 2 through the call channel 8 (step B5), and a timer (not shown) To wait for a response signal from the mobile station 2 (step B6).
Then, the base station 3-i monitors whether or not the response signal from the mobile device 2 is received before the timer times out (determined as YES in step B18) (NO route in steps B7 and B18). ).

By the time-out of the timer, the mobile station 2
Is received, the base station 3-i determines whether the incoming information from the incoming call control station 5 is a line call or a packet call (step B8). If so, the connection processing of the line call is executed (step B).
9) After allocating the dedicated physical channel 11 (step B10), the communication of the line call is started (step B).
11). If no response signal is received before the timer times out, the process from the beginning is executed (NO route in step B18).

In step B8, if the incoming information is packet call information, the base station 3-i
Executes the line connection processing of the packet call (step B21), and thereafter executes the processing of step B22 and thereafter.

The base station 3-i determines whether the communication has been completed or whether a packet line disconnection request has been received from the mobile station 2 or the network 6 (the terminating control station 5) with the packet line connected. 2 to determine whether a request for a handover process has been received from Steps B12, B14 and B1.
(NO route of No. 6), when the communication is completed, the line disconnecting process of the line call is executed (from the YES route of step B12 to step B13). B14 YE
If the request for the handover process is received from the S route (step B15), the handover process is executed (step B).
From step 16 YES, step B17).

By the way, if the packet line is already connected at the time of receiving the incoming information from the network 6 (the incoming call control station 5), the base station 3-i determines whether the incoming information is a line call or a packet call. (From the YES route of step B4 to step B19), and if it is the information of the line call, the processing after step B5 (communication control for the line call) is executed. A call notification (incoming call notification) is sent to the incoming call target mobile device 2 in the visited zone 4-i through the standby channel 9 (step B20).

Then, the base station 3-i determines whether or not the packet flow to be transmitted to the mobile device 2 is large (a predetermined amount or more) (step B22), and if the packet flow is large (YES in step B22). Then, the dedicated physical channel 11 is allocated (step B23), and packet communication with the mobile device 2 is started using the dedicated physical channel 11 (step B24).

Further, the base station 3-i monitors whether a packet line disconnection request has been received from the mobile station 2 or the network 6 (the terminating control station 5) side or a handover processing request has been received from the mobile station 2 respectively. (NO route of steps B25 and B27), if a request to disconnect the packet line is received, the packet line disconnection process is executed (YES in step B25).
If the request for the handover process is received from the route (step B26), the handover process is executed (step B2).
Step B28 from the YES route of No. 7).

If the packet flow rate is small in step B22, the base station 3-i performs packet communication using the common physical channel 10 (step B29 from the NO route in step B22). Then, the base station 3-i transmits / receives the packet to / from the mobile station 2 at time t.
It monitors whether or not one or more stops (step B30) and also monitors whether a handover request from the mobile device 2 has been received (step B31).

As a result of this monitoring, if the transmission / reception of the packet is stopped for the time t1 or more, the base station 3-i executes the processing after the step B25 (NO route of the step B30) and is stopped for the time t1 or more. If not, the processing from step B1 is executed. At this time, if a handover request has been received from the mobile station 2, the base station 3-
i executes disconnection processing of the packet line (step B3).
If the handover request is not received, the communication on the common physical channel 10 is continued (from the NO route of step B31 to step B29).

When receiving any signal (information) from the mobile station 2 via the uplink common physical channel 10, the base station 3-i determines whether the signal (information) is a transmission request signal or location registration information (information). It is determined whether the received signal is a position registration request) or a packet line disconnection request signal (step B).
Steps B33, B35 and B3 from the YES route of 2
7 NO route).

As a result of this determination, if the signal from mobile station 2 is a transmission request signal, base station 3-i determines whether or not the packet line has been connected (YES route from step B33 to step B34). If it is not connected (if NO is determined in step B34), the processing after step B8 is executed, and if it is connected (step B34).
If YES is determined in step B39), it is further determined whether the transmission request signal is for a line call or a packet call (step B39).

Then, if it is for a line call,
The base station 3-i executes the above-described processing after step B9 (connection processing of a line call), and if it is for a packet call, executes the above-described processing from step B22.
On the other hand, if the signal from the mobile device 2 is the location registration information (location registration request), the base station 3-i connects to the network 6 (the terminating control station 5).
In response to this, for example, the base station ID, the mobile station ID of the mobile station 2 that has issued the location registration request, the line connection state with the mobile station 2, and the like are notified to the network 6 (the incoming call control station 5).
A location registration request is issued for itself and the mobile station 2 (step B36).

If the signal from the mobile station 2 is a packet line disconnection request signal (or if a packet line disconnection request signal is received from the network 6 in step B3), the base station 3 i executes the disconnection processing of the packet line [from the YES route in step B37 to step B38 (or from the YES route in step B3 to step B38).

That is, the base station 3-i (CP
U37) executes the above-described steps B35 and B36, and upon receiving a location registration request from the mobile station 2 (the location registration request unit 21 for each zone transition), the reception control station 5 and its own mobile station 2 Has a function as a location registration request unit 31 for the incoming call control station (see FIG. 8) that issues a location registration request for (1).

The above steps B4, B19 to B2
By executing Step 4, the packet is transmitted from the terminating control station 5 in a state in which the location registration request by the terminating control station location registration request unit 31 has been made (packet line connected, ie, the mobile device 2 is in the packet waiting mode). Upon receipt, the non-response confirmation reception control unit 32, which notifies the mobile station 2 of the arrival of the packet and then makes the packet arrive at the mobile station 2 without confirming the response from the mobile station 2 to the termination notification. It also has functions.

(3) Description of Overall Operation of Wireless Packet Communication System 1 Next, based on the basic operations of the mobile station 2 and the base station 3, the overall operation of the wireless packet communication system 1 of the present embodiment will be described with reference to FIG. This will be described with reference to the time chart shown in FIG. However, the operation focusing on the arrival of a packet will be described below. Note that in FIG. 11, the horizontal axis represents the passage of time.

First, after the power is turned on, the mobile station 2 intermittently receives the call channel 8 (step S1, FIG. 13).
Step A8). In this state, when a packet is transmitted from the terminating control station 5 to the base station 3-i (step S
2) The base station 3-i notifies the mobile station 2 of the arrival of the packet through the paging channel 8 (step S3).
Step B5 in FIG. 12).

When the mobile station 2 receives this incoming call notification by intermittent reception of the call channel 8 (step S4),
A response signal is returned to the base station 3-i through the uplink common physical channel 10 (step S5, step A in FIG. 13).
10). When the base station 3-i receives this response signal,
After performing the packet line connection process (step B21 in FIG. 12), if the packet flow rate is small, the received packets are sequentially transferred to the mobile station 2 through the uplink common physical channel 10 (steps S6, S2 ', S6', FIG. Twelve steps B29).

Thereafter, when the time t1 elapses until the next packet is received, the mobile station 2 enters the packet waiting mode, in which the mobile station 2 enters the common physical channel 1 with the base station 3-i.
0 to send or receive control information, thereby notifying or confirming the packet standby mode (in some cases, the uplink (notification) transmission may not be performed).
And the packet waiting channel 9 is intermittently received at the timing as described above with reference to FIG.
8. Steps A43 and A46 in FIG.

[0094] At this time, the mobile device 2 detects the shift of the zone 4-i in which the mobile device 2 is located due to its own movement.
The location registration request has been made to the base station 3-i (step A39 in FIG. 14), and upon receiving this location registration request, the base station 3-i sends a call to the terminating control station 5 for itself and the mobile station 2. (Step B3 in FIG. 12)
6) Thus, the incoming call control station 5 is notified of which mobile station 2 in the packet waiting mode exists in the wireless communication zone 4-i of which base station 3-i.

Thus, when a packet addressed to the mobile station 2 is received from the network 6, the incoming call control station 5 determines which base station 3-i the mobile station 2 that is in a packet waiting state for the packet receives. Since it is known whether or not the mobile station 2 exists in the zone 4-i, the packet received from the network 6 is transmitted to the base station 3-i without performing any special processing for specifying the zone 4-i where the mobile station 2 is located. (Step S9).

When receiving this packet from the incoming call control station 5, the base station 3-i notifies the mobile station 2 of the incoming packet through the packet waiting channel 9 because the packet line has already been connected. (Steps S10 and S11, Step B20 in FIG. 12), the packet received from the incoming call control station 5 is transmitted to the mobile device 2 without confirming the response signal to the incoming call notification (step S12).

If the packet flow rate to be transmitted at this time is small, the base station 3-i is connected to the downlink common physical channel 1
0 is transmitted (step B29 from the NO route of step B22 in FIG. 12), and if the packet flow rate is large, the dedicated physical channel 11 is allocated.
The packet received through the dedicated physical channel 11 is transmitted to the mobile device 2 (YES in step B22 in FIG. 12).
Steps B23 and B24 from the route).

As described above, according to the wireless packet communication system 1 (packet transfer method) of the present embodiment, the mobile station 2 changes every time the zone 4 -i moves within the zone 4 -i due to its own movement while waiting for a packet. Since the location registration request is made, the base station 3-i transmits (forwards) the packet received from the terminating control station 5 to the mobile station without confirming the response from the mobile station 2 to the packet arrival notification. The packet can be reliably received (received) by the destination mobile device 2.

Therefore, the packet transfer delay and the probability of non-delivery of a packet when a response confirmation fails due to collision of a response signal or the like can be greatly reduced, and the reliability and serviceability of packet communication are greatly improved. be able to. Further, in the present embodiment, the arrival notification of the packet from the base station 3-i is performed by using the packet waiting channel 9 and the arrival notification of the line call is performed by using the paging channel 8, and the mobile station 2 Since each of the channels 8 and 9 is intermittently received, the notification of the arrival of the packet and the notification of the arrival of the line call are performed on the individual channels. Therefore, while the effective use of the capacities of the channels 8 and 9 is being performed, the line call reception control can be performed to perform the line call communication even in the packet waiting mode, and the reliability of the packet communication and the line call communication can be improved. It has greatly contributed to the improvement.

Further, in the present embodiment, as described above with reference to FIG. 6, it is possible to simultaneously transmit the respective channels 8 and 9 from the base station 3-i and simultaneously receive the respective channels 8 and 9 from the mobile station 2. Since it is possible, the intermittent rate of the intermittent reception is improved and the power consumption of the mobile station 2 and the base station 3-i can be greatly reduced as compared with the case where each channel 8, 9 is transmitted and received at individual timing.

Description of the First Modification In the above-described embodiment, the mobile station 2 sends a location registration request to the base station 3- every time the mobile station 2 moves to the zone 4-i in the packet waiting mode. However, in this case, for example, when the mobile device 2 is moving at high speed, the number of transitions to the visited zone 4-i increases.
The location registration request must be made frequently, which may increase power consumption.

Therefore, in the first modified example, the C
In the packet waiting mode (when the packet waiting channel 9 is intermittently received) by the PU 29 (zone registration request unit 21 for each zone transfer), the time until the next packet waiting channel 9 is received is a predetermined time ta (for example, several seconds to several seconds). Do not make a location registration request until it is less than several tens of seconds.

That is, as indicated by the diagonal lines in FIG. 16, after receiving the broadcast information from the base station 3-i in step A38, the mobile station 2 determines whether or not the calling area 7 has been shifted. (Step A381) As long as the call area 7 has not been shifted (NO in Step A381), it is determined whether or not the time until intermittent reception of the next packet waiting channel 9 has become ta or less. (Step A382).

As a result of this determination, if the value is less than or equal to ta until the next packet standby channel 9 is intermittently received, the mobile station 2 transmits the base station through the uplink common physical channel 10 in the same manner as in the above-described embodiment. A position registration request is made to 3-i (from the YES route of step A382 to step A39), and if not less than ta, no position registration request is made (NO route of step A382). The processes (steps) other than these steps A381 and A382 are all the same as the processes described above with reference to FIG.

That is, mobile station 2 makes a location registration request even if it detects a shift of zone 4-i until there is a possibility of receiving an incoming call notification by intermittently receiving packet standby channel 9 next time. There is no. For example, as shown in FIG. 15, a case is considered where the mobile device 2 moves sequentially through zones 4-1 to 4-5. At this time, the mobile station 2 issues a location registration request when shifting from the zone 4-1 to the zone 4-2, and the time until the next packet waiting channel 9 is received is 10 minutes, and the time ta is 10 seconds. Suppose there is.

Then, it is assumed that the mobile device 2 moves to the zone 4-4, as indicated by a broken line, 9 minutes after the above-mentioned position registration request, and moves to the zone 4-5 10 minutes later, for example. In this case, the mobile station 2 determines the position when the time ta until receiving the next packet waiting channel 9 becomes 10 seconds or less, that is, when 9 minutes and 50 seconds have elapsed after the previous position registration request. Since the registration request can be made, the location registration request is not made when shifting from the zone 4-2 to the zone 4-3 or the zone 4-3 to the zone 4-4, and the zone 4-4 to the zone 4-5. The next location registration request will be made only when shifting to.

Thus, even when the number of transitions to the zone 4-i increases, such as when the mobile device 2 is moving at high speed, the mobile device 2 needs to frequently perform a position registration request accordingly. Disappears. Therefore, the power consumption of the mobile device 2 can be further reduced. Description of Second Modification Next, in the above-described embodiment, the incoming call notification of the line call in the packet waiting mode is performed through the call channel 8 and the incoming call notification of the packet is performed through the packet waiting channel 9. Each incoming call notification may be made using only the packet waiting channel 9.

That is, in the second modification, the base station 3-i
The (CPU 37: non-response confirmation incoming call control unit 32) is configured to perform packet call incoming notification and line call incoming notification at a predetermined cycle using the packet waiting channel 9 (packet channel information 94). Station 2 (CPU
29: The non-response packet reception control unit 22) is configured to control the reception of the line call when the received packet waiting channel 9 is the notification of the arrival of the line call.

Therefore, in the base station 3-i, as shown in the step B20 from the YES route of the step B4 in FIG. 17, the incoming information from the network 6 when the packet line is already connected (in the packet waiting mode) is transmitted as the line call. , Packet notification, the mobile station 2 is notified of the incoming call through the packet waiting channel 9 (step B in FIG. 12).
19 is omitted), and thereafter, a line call or a packet call is determined (step B39 '), and the reception of the line call or the packet call is controlled according to the result. The other processes (steps with the same step numbers as those in FIG. 12) are executed in the same manner as the processes described above with reference to FIG.

On the other hand, as shown in FIG. 18, the mobile station 2 receives only the packet waiting channel 9 in the packet waiting mode (step A46), and returns to the base station 3-i.
, It is determined whether the incoming notification is for a line call or a packet call (step A4).
From the YES route of No. 7 to step A42), an operation of controlling the reception of a line call or a packet call is performed according to the result of the determination (that is, steps A43 to A45 shown in FIG. 16).
Is omitted).

As a result, as shown in step S14 of FIG. 19, for example, as shown in step S14 of FIG. 19, if only the packet waiting channel 9 is monitored (intermittent reception), the arrival notification of the packet is reliably transmitted. Recognize and control packet reception,
Since the reception control of the line call other than the packet can be performed, it greatly contributes to the versatility of the mobile device 2 and the improvement of the reliability of the packet communication and the communication other than the packet communication (the line call).

It is to be noted that, contrary to the above-described example, for example, FIG.
As shown in step S13, the base station 3-i notifies the mobile station 2 of a line call and a packet call to the mobile station 2 through the paging channel 8, and the mobile station 2 transmits only the paging channel 8 in the packet waiting mode. , The same operation and effect as described above can be obtained.

However, in this case, the calling channel 8
Is not used only in the zone 4-i of one base station 3-i like the packet waiting channel 9,
Zone 4 of a plurality of base stations 3-i called paging area 7
-I is used in the area including the i.
-It is necessary to carry information indicating whether the information is for i.

Description of Third Modification By the way, the intermittent reception interval (period) may be changed in accordance with a user's request for packet communication quality. That is, the mobile station 2 (CPU 29: non-response packet reception control unit 22) is configured so that the intermittent reception cycle can be changed according to the user's packet communication quality request, and the base station 3-i (CPU 37: Non-response confirmation incoming call control unit 32)
To channel 8, according to the above packet communication quality requirement.
9 can be changed.

Here, the packet communication quality requirement includes, for example, (a) the transition time to the packet waiting mode (the time t1), (b) the packet allowable delay time in the packet waiting mode, and (c) ) The communication mode of the mobile device 2 (packet transmission only mode, packet reception only mode, packet transmission / reception dual mode) and the like can be considered.

For example, if the transition time t1 in (a) is set to be short and the mode is shifted to the packet waiting mode immediately after the transmission / reception of the packet is stopped, the user wants to reduce the battery consumption as much as possible. As it seems, the mobile device 2 sets the intermittent reception cycle longer,
The base station 3-i also sets (changes) the transmission cycle of the channels 8 and 9 in accordance with this setting.

Conversely, if the transition time t1 in (a) is set to be long and the transmission / reception of the packet is stopped so that the transition to the packet waiting mode is not performed for a while, the user can reduce the battery consumption. Since the user wants to give priority to the immediate reception of the packet over the reduction of the number, the mobile station 2 sets the intermittent reception cycle to be short, and the base station 3-i also changes the transmission cycle of the channels 8 and 9 in accordance with this setting. .

For example, if the packet allowable delay time in the above (b) is set short, the user wants to receive the packet without delay, so the mobile station 2 sets the intermittent reception cycle short, and this setting is made. Base station 3-i
Also changes the transmission cycle of channels 8 and 9. Conversely, if the packet allowable delay time in (b) is set to be long, the user may want to reduce the battery consumption of the mobile device 2 instead of delaying the packet reception. Sets a long intermittent reception cycle, and the base station 3-i also changes the transmission cycle of the channels 8 and 9 in accordance with this setting.

The following Table 1 shows the permissible packet delay when the transmission time per superframe of channels 8 and 9 is t and the transmission time per group is t / m as shown in FIG. An example of an intermittent reception cycle (call interval) according to time and an allocation group in a superframe is shown in Table 2 below, where t = 640 msec and m = 256 (t /
A specific example of Table 1 when m = 15 msec) is shown.

[0120]

[Table 1]

[0121]

[Table 2]

Further, when the communication mode of (c) is a packet transmission only mode, it is not necessary to wait for a packet. Since reception is considered necessary, the mobile station 2 automatically sets the longest cycle of the intermittent reception cycles requested by the system 1 (the base station 3-i) as its own intermittent reception cycle. Also, in order to wait for a line call, the intermittent reception cycle required for the line call is automatically set as its own intermittent reception cycle. In other modes, packets can be received, so an intermittent reception cycle is set according to the user's request.

If there is no setting for requesting the packet communication quality from the user, the mobile station 2 defaults (initial setting).
It operates according to the value (intermittent reception cycle), and the base station 3-i operates accordingly. Further, the intermittent reception interval (period) may be changed in accordance with the presence or absence of a communication delay with the communication partner of the mobile device 2 in addition to the packet communication quality request. That is, the base station 3-i (CP
U37: The non-response confirmation incoming call control unit 32) can change the transmission cycle of the channels 8 and 9 in accordance with the presence or absence of a communication delay with the communication partner of the mobile station 2 in addition to the above packet communication quality request. The mobile station 2 (CPU 29: non-response packet reception control unit 22) is configured to be able to change the intermittent reception cycle according to the presence or absence of the communication delay.

As a result, for example, as shown in FIG.
When the communication partner of the mobile station 2 is a fixed station 5B such as a server (it is considered that there is no delay time), the mobile station 2 is connected to the network 6 via the base station 3 'and the incoming call control station 5A in the same manner as the mobile station 2 itself. Device 2 '(or other mobile device 2: delay time occurs)
According to the case, the transmission cycle of the channels 8 and 9 of the base station 3-i and the intermittent reception cycle of the mobile station 2 can be changed. However, the base station 3-i (or 3 ') is
It is assumed that the communication partner can be recognized based on information such as the telephone number of the partner included in the transmission request (or 2 ′).

For example, the communication partner of the mobile station 2 is the fixed station 5B.
, It is considered that there is no delay time.
As described above, the base station 3-i and the mobile device 2 transmit a transmission cycle,
What is necessary is just to set (change) the intermittent reception cycle. On the other hand, if the communication partner of the mobile device 2 is the mobile device 2 ′ (or another mobile device 2), a delay time occurs. There is a possibility that communication may not be successful. Therefore, the base station 3-i and the base station 3 'respectively transmit the channels 8 and 9 in accordance with the intermittent reception cycle set in accordance with the packet communication quality request of one of the users (mobile units 2 and 2'). And either one of the mobile units 2, 2 '
Also change the intermittent reception cycle. In this case, the setting may be adapted to the user with higher priority or the base station 3-i, 3 '.

As described above, the intermittent reception cycle of the mobile station 2 and the transmission cycle of the channels 8 and 9 of the base station 3-i can be changed according to the user's request for packet communication quality.
In addition to the packet communication quality request, the intermittent reception cycle of the mobile device 2 and the base station 3-i according to the presence or absence of a communication delay between the mobile device 2 and the communication partner (in consideration of the communication delay with the communication partner)
Can be changed, the power consumption of the base station 3-i and the mobile device 2 can be reduced, and the reliability of communication can be greatly improved.

Others In the above-described embodiment and each of the modifications, the present invention is not limited to C.
Although the case where the DMA system is applied has been described as an example, the present invention is not limited to this, and other systems such as a TDMA (Time Division Multiple Access) system and an FDMA (Frequency Division Multiple Access) system can also be applied. . In particular, since the system 1 described in the second and third modifications is configured to monitor any one of the channels 8 and 9, the TDMA method or the FD
It can also be realized by the MA method.

Further, the above-described mobile station 2 and base station 3-i
May be provided independently as elements for constructing the wireless packet communication system 1 described above. The present invention is not limited to the above-described embodiment and each modified example, and can be variously modified and implemented without departing from the gist of the present invention.

[0129]

As described in detail above, according to the present invention,
Since the mobile station issues a location registration request every time the base station changes its wireless communication zone in accordance with its own movement while waiting for a packet, the base station moves in response to an incoming notification of packet data (hereinafter, simply referred to as "packet"). Even if a packet received from the incoming control station is transmitted (transferred) to the mobile station without confirming the response from the station, the packet can be reliably received by the target mobile station. Therefore, the packet transfer delay and the probability of non-delivery of a packet due to a failure in response confirmation can be significantly reduced, and the reliability and serviceability of packet communication can be greatly improved (claims 1, 9, 17). , 24).

Here, if a notification of the arrival of a packet is transmitted from the base station using the packet channel information of the packet waiting channel, and the mobile station intermittently receives the packet channel information while waiting for the packet,
Mobile station monitors even packet channel information (intermittent reception)
If this is done, it is possible to reliably recognize the notification of the arrival of the packet and control the reception of the packet, which greatly contributes to the improvement of the reliability of the packet communication.
0,18).

Further, not only the notification of the arrival of the packet but also the notification of the arrival of communication data other than the packet is transmitted using the above-mentioned packet channel information, so that the mobile station receives the packet channel information intermittently. The mobile station can receive communication data other than the packet even while waiting for a packet (during intermittent reception), and greatly contributes to the improvement of the versatility of the mobile station and the reliability of the packet communication and the communication other than the packet communication ( Claims 3, 11, 19).

In addition, the above-mentioned notification of the arrival of a packet from the base station is performed using the packet channel information of the packet waiting channel, and the notification of the arrival of communication data other than the packet is performed using the paging channel information of the paging channel. If the station intermittently receives the respective channel information, the notification of the arrival of the packet and the notification of the arrival of the communication data other than the packet are performed on the individual channels, respectively. Thus, it becomes possible to receive communication data other than the packet waiting for the packet. Therefore, it greatly contributes to further improving the reliability of packet communication and communication other than packet communication (claims 4, 12, and 20).

Here, the base station can spread the packet channel information and the paging channel information with different codes and transmit them, so that each incoming notification can be made simultaneously through each of the above channels, If the mobile station separates the channel information from the base station by despreading and demodulating the channel information with the different codes, the base station can transmit the channel information at the same time. Therefore, power consumption can be significantly reduced as compared with a case where each channel information is transmitted individually. Also, since the mobile station can simultaneously receive each channel information from the base station, its power consumption can be significantly reduced (claims 5, 13, 21).

Further, if the mobile station does not make the location registration request until the time until the next packet channel information is received during the above-mentioned packet waiting is shorter than a predetermined time, then the mobile station Since there is no need to make a location registration request to the terminating control station until the reception of the information may result in a packet arrival notification, the power consumption can be further reduced (claims 6 and 14). .

Further, according to the present invention, the intermittent reception cycle of the mobile station and the transmission cycle of the channel information of the base station can be changed according to the user's request for packet communication quality. Otherwise, the power consumption of the base station and the mobile station can be reduced by extending the intermittent reception cycle.
22).

According to the present invention, in addition to the above-mentioned packet communication quality requirement, the intermittent reception cycle of the mobile station and the transmission cycle of the channel information of the base station are determined according to the presence or absence of a communication delay with the communication partner of the mobile station. Since it can be changed, the intermittent reception cycle can be changed in consideration of the communication delay between the mobile station and the communication partner of the mobile station, which greatly contributes to improvement of communication reliability. (Claims 8, 16, 23).
