Description

Idle mode processing method

Technical Field

The invention relates to the field of communication, in particular to an idle mode processing method.

Background

In a wireless communication system, radio coverage is provided by a Base Station (BS) using a specified radio channel within a geographic area, referred to as a cell. Usually, the base station is located in the center of the cell in theory. The base stations may be classified into macro base stations (macro bs), micro base stations (PICOBS), and pico base stations (femtocells lbs) according to the size of a coverage area. In addition, in order to extend coverage or extend capacity, one or more relay stations may be placed between a mobile station (e.g., a terminal or a mobile terminal) (MS for short) and a base station. For a mobile station, a relay station is equivalent to a base station. When a mobile station moves from one cell to another, a handover is required in order to maintain communication.

According to the supported communication protocols, the base station/relay station may be divided into an advanced control station and a legacy control station, where the advanced control station refers to a base station/relay station (advanced base station/advanced relay station, abbreviated as ABS/ARS) supporting the advanced communication protocol, and the legacy control station refers to a base station/relay station (yardstickbase station/yardstickrelay station, abbreviated as YBS/YRS) supporting the legacy communication protocol. In the technique considering compatibility, for the advanced control station, its frame is divided into a first area and a second area. The second region may support legacy communication protocols and may therefore also be referred to as a legacy region, and the first region may only support advanced communication protocols and may therefore also be referred to as an advanced region. Similarly, for a mobile station, it can be divided into an Advanced Mobile Station (AMS) and a legacy mobile station (YMS), and the advanced mobile station can operate in the first area or the second area, while the legacy mobile station can operate only in the second area. For a legacy mobile station, the second area of the advanced control station corresponds to a legacy control station. In addition, when the advanced mobile station accesses the conventional control station, the advanced mobile station is a conventional mobile station for the conventional control station. The advanced control station may also support only the advanced communication protocol, in which case the advanced control station may only have the first zone.

The following is further described by taking the IEEE802.16 standard as an example. The IEEE802.16 standard is an advanced air interface standard proposed for the microwave band, and the standard defines specifications of a physical layer (PHY) and a Media Access Control (MAC) layer. The IEEE802.16m including the relay structure is the most advanced standard technology in the current IEEE802.16 standard, and the IEEE802.16m (hereinafter, referred to as 16m) is based on the traditional standards such as the IEEE802.16e (hereinafter, referred to as 16e) and the IEEE802.16j (hereinafter, referred to as 16 j).

Based on the above description, in a system supporting the IEEE802.16 standard, an advanced control station (i.e., a base station/relay station supporting the 16m protocol) can be compatible with a legacy mobile station (a mobile station supporting the 16e protocol), and likewise, an advanced mobile station (a mobile station supporting the 16m protocol) should be able to access a legacy control station (a base station supporting the 16e or a relay station supporting the 16 j).

The first zone (also referred to as an advanced zone, 16MZone for short) may support the advanced communication protocol defined by 16m, and the second zone (also referred to as a legacy zone, LegacyZone for short, LZone) may support the protocol of 16e/16 j. Furthermore, the advanced control station may also only have MZone.

Generally, when a control station in a system evolves from a legacy control station to an advanced control station, a network (also referred to as an access service network, referred to as ASN) to which the control station is connected also evolves from the legacy network to the advanced network. However, in an actual system, since the development speeds of the control station and the access service network are not necessarily synchronized, or market development requires that advanced technology be used as soon as possible, a situation occurs in which the control station is an advanced control station and the access service network is a conventional network, fig. 1 is a schematic diagram of a system evolution network deployment according to the related art, as shown in fig. 1, an advanced mobile station can access a conventional control station, a mixed-mode advanced control station supporting both a conventional protocol and an advanced protocol, and an advanced control station supporting only an advanced protocol; and the legacy mobile station may access the legacy control station and the mixed mode advanced control station. At this time, if the advanced communication protocol is directly used over the air interface of the advanced mobile station and the advanced control station (in fig. 1, the thicker solid line identifies the interface of the advanced mobile station and the advanced control station), without any change, there is a possibility that a problem may occur in the subsequent communication with the conventional network.

For example, to save power, a mobile station (e.g., a mobile terminal, a terminal) may enter an Idle (Idle) mode, after which the mobile station only periodically receives downlink broadcast data at discrete intervals, and during movement between multiple control stations, updates location information to the control stations only when needed, without performing handover and network reentry. There is a large difference between the legacy control station/legacy mobile station and the advanced control station/advanced mobile station in the handling of the Idle mode. Taking the 16e and 16m standards as examples, the identification method of the paged mobile station is completely different between the two standards. When a control station supporting the 16e protocol pages a mobile station, a transmitted paging broadcast (MOB _ PAG-ADV) message contains 24-bit MAC address hash (MAC address hash) information calculated according to the MAC address of the paged mobile station, and the mobile station supporting the 16e protocol identifies whether the mobile station is paged by the control station according to whether the received MOB _ PAG-ADV message contains the corresponding MAC address hash or not in a paging listening interval; when a mobile station supporting the 16m protocol requests to enter Idle mode, the system supporting the 16m protocol assigns a 10-bit de-registration identifier (DID) to the mobile station, and the DID is used to identify the mobile station in the subsequent paging procedure, for example, the mobile station identifies whether the mobile station is paged according to whether the received advanced paging broadcast message (AAI _ PAG-ADV) sent by the 16m control station contains its assigned DID.

As can be seen from the above description, if the access service network accessed by the advanced control station is a conventional network, problems may occur if the advanced control station performs idle related processing on the mobile station by using the advanced protocol.

Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Example one

In this embodiment, a method for paging an idle mode mobile station is provided, the method comprising: an advanced control station connected to a legacy network pages a mobile station in its first area using a paging identification used by the mobile station in a legacy protocol.

It should be noted that in this embodiment, the advanced control station may include an advanced control station having a first area and a second area, or may be an advanced control station having only a first area.

In the embodiment, the paging identifier used by the mobile station in the traditional protocol is used for paging, so that the problem of connecting the traditional access network can be solved, the idle mode can adapt to the evolution normal operation of the system, and the aim of saving power can be fulfilled.

In the present embodiment, two ways are used for implementation, which will be described below.

In a first mode

The advanced control station takes a paging identifier used by a mobile station needing to enter the idle mode in a traditional protocol as a de-registration identifier of the mobile station, and sends the de-registration identifier to the mobile station needing to enter the idle mode in the first area. It should be noted that the advanced control station may carry a deregistration identifier in a message sent to the mobile station, and the message capable of carrying the deregistration identifier can achieve the same purpose, for example, the message may be a deregistration response message, that is, the advanced control station carries the deregistration identifier in the deregistration response message and sends the deregistration response message to the mobile station that needs to enter the idle mode in the first area.

Preferably, the mobile station may first send a de-registration request message to the advanced control station in the first area to request entry into the idle mode, and the advanced control station sends a de-registration response message to the mobile station in the first area after receiving the de-registration request message; alternatively, the advanced control station may also actively send a deregistration response message to the mobile station in the first zone to trigger the mobile station to enter the idle mode.

In this manner, if the advanced control station performs paging by transmitting a paging broadcast message, the paging broadcast message carries a paging identifier used in a conventional protocol by the mobile station to be paged.

Mode two

In this method, before the advanced control station pages the mobile station in the idle mode, the advanced control station transmits an indication message for indicating that the mobile station that needs to enter the idle mode uses a paging indicator used in the conventional protocol.

Preferably, the advanced control station may carry the indication information in a superframe header and send the superframe header, that is, the advanced control station sends the superframe header containing the paging identification type information adopted by the advanced control station; the advanced control station pages the mobile station according to the paging identification type indicated by the superframe header. The paging identification type comprises a traditional technology (or protocol) paging identification and an advanced technology paging identification. The mobile station can adopt the paging identification of the traditional technology or the paging identification of the advanced technology to carry out paging identification and location updating according to the paging identification type indication of the super frame header.

After the mobile station receives the super frame header, a deregistration request message can be sent to the advanced control station to request to enter an idle mode, and after the deregistration request message is received by the advanced control station, a deregistration response message is sent to the mobile station by the advanced control station, wherein the deregistration identifier of the mobile station is not carried in the deregistration response message by the advanced control station; alternatively, the advanced control station may actively send a de-registration response message to the mobile station without carrying the de-registration identifier of the mobile station to trigger the mobile station to enter the idle mode.

If the advanced control station sends the paging broadcast message to page, the paging broadcast message carries the paging identifier used by the mobile station needing to be paged in the traditional protocol and the information for indicating the number of the mobile stations paged by the advanced control station by using the paging identifier of the traditional protocol.

Preferably, the indication information transmitted by the advanced control station in the superframe header may be 1 bit. If the indication bit is "0" to indicate that the advanced protocol identification is used, the indication bit is "1" to indicate that the conventional protocol identification is used, and vice versa. The indication information may also be multiplexed with an indication of the type of network access identifier used by the system when the mobile station performs network access.

In the two modes, the advanced control station can send paging broadcast messages to perform paging in the first area and the second area; or, the advanced control station may also acquire a communication area corresponding to the mobile station that needs to be paged, and send a paging broadcast message to perform paging in the communication area corresponding to the mobile station that needs to be paged, for example, if the advanced control station acquires that the mobile station corresponds to the first area, the advanced control station sends the paging broadcast message in the first area; for another example, if the advanced control station can acquire the communication area information corresponding to the mobile station, the advanced control station only transmits the paging broadcast message in the corresponding area to page the mobile station; otherwise the advanced control station pages the mobile station in both the first area and the second area.

Preferably, the advanced control station may acquire a communication area corresponding to the mobile station to be paged by at least one of: the advanced control station acquires a communication area corresponding to a paging group according to the paging group identification or the paging cycle of the paging group to which the mobile station needing paging belongs; the advanced control station acquires a communication area for the mobile station needing paging to enter an idle mode or carry out location updating from a paging controller, wherein the communication area is a communication area corresponding to the advanced control station; the advanced control station acquires a communication area corresponding to a paging group to which a mobile station to be paged belongs from the paging controller.

Preferably, different communication areas of the advanced control station are divided into different paging groups, and the paging groups belonging to the different communication areas may be distinguished using different paging group identifications, for example, using high bits of a paging group identifier to distinguish the paging groups of the first area and the second area; paging groups belonging to different communication areas may also be distinguished using different paging cycles. The advanced control station can judge the communication area of the mobile station to be paged according to the paging group to which the paged mobile station belongs, and pages the mobile station in the corresponding area.

After receiving the paging broadcast message, the mobile station in the idle mode determines whether the paging broadcast message carries a paging identifier consistent with a paging identifier used in a conventional protocol and locally generated by the mobile station (corresponding to the above-mentioned manner two) or received from the advanced control station (corresponding to the above-mentioned manner one), so as to determine whether the mobile station is paged. That is, in the first mode, the mobile station in the paging listening interval recognizes whether it is paged or not according to the received paging broadcast message and the pre-assigned deregistration identifier.

Under the condition that the mobile station in the idle mode determines that the mobile station is paged, the mobile station in the idle mode ends the idle mode according to the indication of the paging broadcast message, and then network reentry is carried out; or, the mobile station in the idle mode sends a ranging request message carrying a paging identifier (corresponding to the first mode) or a medium access address (corresponding to the second mode) used by the mobile station in a conventional protocol to the advanced control station according to the paging broadcast message; the advanced control station returns a ranging response message carrying a paging identifier (corresponding to the mode one) or a medium access address (corresponding to the mode two) used by the mobile station in a traditional protocol; the mobile station in idle mode completes the location update.

Preferably, the paging identifier used by the mobile station in the conventional protocol may be a hash value of a Media Access Control (MAC) address of the mobile station, for example, 24 bits. Accordingly, the deregistration identifier field in a system message containing the deregistration identifier extends to the same length as the MAC address hash of the mobile station, the system message including at least one of: a de-registration response message, a paging broadcast message, a ranging request message, and a ranging response message.

Example two

In the embodiment of the present invention, the apc station refers to an apc station having a first zone and a second zone, fig. 2 is a flowchart of a method for paging an idle mode mobile station according to a second embodiment of the present invention, the method includes the following steps:

step S202, the advanced control station connected to the conventional network instructs the mobile station advanced control station to support the mobile station to perform idle mode processing only in the second area using the conventional protocol; and the number of the first and second groups,

in step S204, the advanced control station pages the idle mode mobile station in the second area using the conventional protocol.

In this embodiment, the advanced control station uses the conventional protocol processing in the second area, so that the problem of connecting to the conventional access network can be solved, the idle mode can adapt to the evolution of the system and work normally, and the purpose of saving power can be achieved.

In step S202, the advanced control station instructs the mobile station to support idle mode processing only by the mobile station in its second area using the legacy protocol by at least one of: the advanced control station and the mobile station carry out capability negotiation; the advanced control station transmits the indication information. For example, the mobile station may perform capability negotiation with the advanced control station or learn, through indication information included in a superframe header or other message broadcast by the advanced control station, that the advanced control station only supports idle mode processing of the mobile station in the second area in the manner of a legacy control station.

Preferably, the mobile station enters the idle mode in the second area after the advanced control station instructs the mobile station. There are two ways for the mobile station to enter the idle mode in the second zone, which will be described separately below.

In the first mode, the mobile station operating in the second area enters the idle mode in the second area. The second mode is that the mobile station working in the first area of the advanced control station is switched to the second area and enters the idle mode in the second area, wherein, the mobile station is switched from the first area to the second area and sends a deregistration request message to the advanced control station in the second area to request to enter the idle mode; alternatively, the advanced control station triggers the mobile station to transition from the first zone to the second zone and sends a deregistration response message to the mobile station to cause the mobile station to enter an idle mode.

After the mobile station enters the idle mode in the second area, the mobile station acquires the paging broadcast message sent by the advanced control station in the second area, and determines whether the paging broadcast message is paged according to whether the paging broadcast message carries the hash value of the media access address of the mobile station, namely, the mobile station acquires the paging broadcast message sent by the advanced control station in the second area at a paging monitoring interval, and judges whether the paging broadcast message is paged according to whether the paging broadcast message contains the hash value of the MAC address of the mobile station. It should be noted that the advanced control station may transmit the paging broadcast message only in its second area.

In case the mobile station determines that it is paged, the mobile station performs location update or network re-entry in the second area according to the indication information in the paging broadcast message.

Preferably, the mobile station transitions to the first area in case of completing the network re-entry or during the network re-entry; the zone switch can be initiated by the mobile station or the advanced control station.

Other preferred embodiments of the present invention will be described below. First to sixth preferred embodiments are descriptions of the first embodiment, that is, the advanced control station connected to the legacy access network performs paging identification in the first area using the MAC address hash of the mobile station as a deregistration identifier; seventh to twelfth preferred embodiments are descriptions of the second mode in the first embodiment, that is, the advanced control station connected to the legacy access network sends the paging identifier type information used in the secondary superframe header, and uses the corresponding paging identifier in the subsequent paging processing. The mobile station carries out subsequent paging judgment according to the paging identification type indicated in the auxiliary superframe header; the thirteenth and fourteenth preferred embodiments are descriptions of the second embodiment, i.e., the advanced control station connected to the legacy access network supports only the idle mode processing of the mobile station in the second area in the manner of the legacy control station. When the mobile station and the advanced control station carry out capability negotiation or indication information contained in a superframe header message broadcast and sent by the advanced control station learns that the advanced control station only supports the mobile station to carry out idle mode processing in the second area according to the mode of a traditional control station.

Preferred embodiment 1

The mobile station accesses an advanced control station, which is an advanced control station having only the first area and is connected to a legacy access network. The mobile station may wish to enter an idle mode because there is no data transmission need for the time being. The mobile station actively sends a de-registration request message (AAI _ DREG-REQ) to the advanced control station to request to enter an idle mode. Fig. 3 is a flowchart of the advanced control station process according to a first preferred embodiment of the present invention, and the advanced control station process includes the following steps:

step S302, after receiving the request, the advanced control station generates 24-bit MAC address hash according to the MAC address of the mobile station;

the advanced control station transmits the MAC address hash as a de-registration identifier (DID) to the mobile station through a de-registration response message (AAI _ DREG-RSP) at step S304.

The deregistration response message also includes a paging group information assigned to the mobile station, such as a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, etc. After the mobile station enters the idle mode, a paging broadcast message (AAI _ PAG-ADV) is periodically received at a paging listening interval according to the assigned paging cycle and paging offset information.

The paging broadcast message is periodically transmitted by the advanced control station and contains mobile station de-registration identifier information (equivalent to a mobile station MAC address hash) that needs to be transmitted to the mobile station or that requires a location update. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment two

The mobile station accesses an advanced control station, which is an advanced control station having only the first area and is connected to a legacy access network. Since there is no data transmission requirement temporarily, the advanced control station expects the mobile station to enter an idle mode.

The advanced control station generates a 24-bit MAC address hash from the MAC address of the mobile station and sends it as a de-registration identifier (DID) to the mobile station via a de-registration response message (AAI _ DREG-RSP) (the steps are similar to those in fig. 3, which have been described in the first preferred embodiment and will not be described here again).

The deregistration response message also includes information of a paging group assigned to the mobile station, such as a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, and the like. After receiving the deregistration response message, the mobile station sends a deregistration request message (AAI _ DREG-REQ) to the advanced control station to confirm that the advanced control station enters the idle mode. After the mobile station enters the idle mode, a paging broadcast message (AAI _ PAG-ADV) is periodically received at a paging listening interval according to the assigned paging cycle and paging offset information.

The paging broadcast message is periodically transmitted by the advanced control station and contains mobile station de-registration identifier information (equivalent to mobile station MAC address hash) that needs to be transmitted to the mobile station or that requires a location update. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment three

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. The mobile station currently accesses the first area of the advanced control station and wishes to enter an idle mode because there is temporarily no data transmission need.

The mobile station actively transmits a de-registration request message (AAI _ DREG-REQ) to the advanced control station in the first region, requesting to enter an idle mode. After receiving the request, the advanced control station generates a 24-bit MAC address hash according to the MAC address of the mobile station, and sends the hash to the mobile station as a Deregistration Identifier (DID) through a deregistration response message (AAI _ DREG-RSP) (steps are similar to those in fig. 3, which have been described in the first preferred embodiment and are not described here again).

The deregistration response message also includes a paging group information assigned to the mobile station, such as a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, etc. In addition, the advanced control station may also actively initiate the idle mode of the mobile station in the first area in a manner similar to that of the second preferred embodiment.

After the mobile station enters the idle mode, a paging broadcast message (AAI _ PAG-ADV) is periodically received in the first area according to the assigned paging cycle and paging offset information at the paging listening interval. The paging broadcast message is periodically transmitted by the advanced control station and contains mobile station de-registration identifier information (equivalent to a mobile station MAC address hash) that needs to be transmitted to the mobile station or that requires a location update.

The mobile station judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment four

After the mobile station enters the idle mode according to the first, second and third preferred embodiments, the mobile station periodically receives a paging broadcast message (AAI _ PAG-ADV) in the first area according to the assigned paging cycle and paging offset information at the paging listening interval.

The paging broadcast message is periodically transmitted by the advanced control station and contains mobile station de-registration identifier information (equivalent to mobile station MAC address hash) that needs to be transmitted to the mobile station or that requires a location update. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If it is a location update, the mobile station sends a ranging request message (AAI _ RNG-REQ) to the advanced control station, in which the de-registration identifier is extended to 24 bits, and accordingly, the ranging response message (AAI _ RNG-RSP) returned by the control station also includes the 24-bit de-registration identifier. After receiving the ranging response message, the mobile station completes the location update and can continue to enter the idle mode.

Preferred embodiment five

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. The mobile station currently accesses the second area of the advanced control station and wishes to enter the idle mode because there is temporarily no data transmission need.

The mobile station actively sends a de-registration request message (DREG-REQ) to the advanced control station in the second region to request to enter the idle mode. The advanced control station, upon receiving the request, transmits a de-registration command message (DREG-CMD) to the mobile station according to the protocol of the legacy control station. The advanced control station may also actively initiate the idle mode in the second zone. After the mobile station enters the idle mode, a paging broadcast message (MOB _ PAG-ADV) is periodically received in the second area according to the assigned paging cycle and paging offset information at the paging listening interval. The paging broadcast message is periodically transmitted by the advanced control station and contains the MAC address hash of the mobile station that needs to be transmitted to the mobile station or that requires a location update. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash information matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment six

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. In preferred embodiments three and five, the mobile station may enter the idle mode through the first area and may also enter the idle mode through the second area, and the mobile station periodically receives a paging broadcast message (AAI _ PAG-ADV) in the corresponding area according to the allocated paging cycle and paging offset information at the paging listening interval. And the paging broadcast message is periodically transmitted by the advanced control station. Fig. 4 is a flow chart of the advanced control station paging mobile station according to the sixth preferred embodiment of the present invention, which comprises the following steps:

step S402, the advanced control station determines whether the information message corresponding to the first area or the second area of the relevant paging group or the information corresponding to the first area or the second area of the mobile station needing paging can be obtained from the paging controller;

step S404, if the information can be obtained, the advanced control station only contains the information of the mobile station needing to be paged in the area in the corresponding area when sending the paging broadcast message in the first area and the second area;

step S406, if the advanced control station cannot acquire the information, the paging broadcast messages sent by the first area and the second area of the advanced control station include all mobile stations that need to be paged.

Different communication areas of the advanced control station are divided into different paging groups, and the paging groups belonging to the different communication areas can be distinguished by different paging group identifications, for example, the paging groups of the first area and the second area are distinguished by using the high bit of the paging group identifier, the highest bit of the paging group identifier being 0 represents the paging group formed by the first area of the advanced control station, and the highest bit of the paging group identifier being 1 represents the paging group formed by the second area of the advanced control station and the conventional control station, or vice versa. Paging groups belonging to different communication areas may also be distinguished using different paging cycles. The advanced control station can judge the communication area of the mobile station to be paged according to the paging group identifier and/or paging cycle to which the paged mobile station belongs, and pages the mobile station in the corresponding area.

The mobile station monitors only the area entering the idle mode and judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the mobile station finds that the paging group identification is not the paging group identification allocated by the mobile station, and the location is updated, the advanced control station can recommend other paging groups of the same type to which the advanced control station belongs to the paging controller according to the paging group identification currently used by the mobile station. If the paging controller recommends that the paging group which is identical to the current paging group is allocated to the mobile station according to the advanced control station, the advanced control station sends the new paging group information to the mobile station, otherwise, the advanced control station requires the mobile station to carry out area switching to the communication area corresponding to the new paging group, and then the mobile station carries out access again.

If the paging controller supports the assignment of a new paging group based on the paging group type to which the mobile station currently corresponds, i.e., the mobile station currently belongs to the first-zone paging group, then the new paging group assigned by the paging controller should also be the first-zone paging group. In this case, the mobile station can directly perform the location update.

In addition, if the advanced control station can directly acquire the mobile station needing to be paged from the paging controller to enter an idle mode or a communication area for location updating or the advanced control station acquires the communication area corresponding to the paging group to which the mobile station needing to be paged belongs from the paging controller, the advanced controller directly pages the mobile station in the corresponding communication area.

If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment seven

The mobile station accesses an advanced control station, which is an advanced control station having only the first area and is connected to a legacy access network. When accessing the advanced control station, the mobile station can obtain the paging identification indication information supported by the advanced control station through a superframe header broadcast and sent by the advanced control station. The paging identification indication is 1 bit, can be indicated independently, and can also be multiplexed with the network access identification type indication, and is used for indicating whether the traditional technology identification or the advanced technology identification is adopted for paging processing. If the indication is that the legacy identifier is used, the mobile station uses the MAC address hash to make a paging determination. If the mobile station wishes to enter the idle mode, it actively sends a de-registration request message (AAI _ DREG-REQ) to the advanced control station requesting entry into the idle mode. Fig. 5 is a flowchart of an advanced control station process according to a seventh preferred embodiment of the present invention, which includes the steps of:

step S502, after the advanced control station receives the request, the advanced control station does not send a Deregistration Identifier (DID) to the mobile station in a deregistration response message (AAI _ DREG-RSP);

in step S504, the advanced control station pages the mobile station according to the MAC address hash.

In the above step, the deregistration response message includes information related to a paging group assigned to the mobile station, for example, a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, and the like.

After the mobile station enters the idle mode, a paging broadcast message (AAI _ RAG-ADV) is periodically received at a paging listening interval according to the allocated paging cycle and paging offset information. The paging broadcast message is periodically sent by the advanced control station, and the message contains information indicating the number of mobile stations paged by the advanced control station by using the traditional protocol paging identifier and the MAC address hash information of the mobile stations needing to be sent to the mobile stations for position updating or network reentry. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the deregistration identifier matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment eight

The mobile station accesses an advanced control station, which is an advanced control station having only the first area and is connected to a legacy access network. When accessing the advanced control station, the mobile station can obtain the paging identification indication information supported by the advanced control station through a superframe header broadcast and sent by the advanced control station. The paging identification indication is 1 bit, can be indicated independently, and can also be multiplexed with the network access identification type indication, and is used for indicating whether the traditional technology identification or the advanced technology identification is adopted for paging processing. If the indication is marked by the traditional technology, the mobile station uses the MAC address hash to perform paging judgment.

If the advanced control station desires the mobile station to enter an idle mode. The advanced control station transmits a Deregistration Identifier (DID) to the mobile station through a deregistration response message (AAI _ DREG-RSP) including information of a paging group allocated to the mobile station, such as a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, etc. After receiving the deregistration response message, the mobile station sends a deregistration request message (AAI _ DREG-REQ) to the advanced control station to confirm that the advanced control station enters the idle mode.

After the mobile station enters the idle mode, a paging broadcast message (AAI _ PAG-ADV) is periodically received at a paging listening interval according to the assigned paging cycle and paging offset information. The paging broadcast message is periodically transmitted by the advanced control station, and contains information indicating the number of mobile stations paged by the advanced control station using the conventional protocol paging identifier and the hash of the MAC address of the mobile station to be transmitted to the mobile station requiring location update or network reentry.

Fig. 6 is a flow chart of a mobile station process according to an eighth preferred embodiment of the present invention, the mobile station process comprising the steps of:

step S602, the mobile station learns that the advanced control station adopts an idle mode without allocating a de-registration identifier;

in step S604, the mobile station determines whether to be paged according to whether the received paging broadcast message contains a MAC address hash matching itself.

If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment nine

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. When accessing the advanced control station, the mobile station can obtain the paging identification indication information supported by the advanced control station through a superframe header broadcast and sent by the advanced control station. The paging identification indication is 1 bit, can be indicated independently, and can also be multiplexed with the network access identification type indication, and is used for indicating whether the traditional technology identification or the advanced technology identification is adopted for paging processing. If the indication is marked by the traditional technology, the mobile station uses the MAC address hash to perform paging judgment.

If the mobile station wishes to enter the idle mode. The mobile station actively transmits a de-registration request message (AAI _ DREG-REQ) to the advanced control station in the first region, requesting to enter an idle mode. The advanced control station transmits a Deregistration Identifier (DID) not to the mobile station through a deregistration response message (AAI _ DREG-RSP). The deregistration response message includes a paging group information assigned to the mobile station, such as a paging group identifier, a paging controller identifier, a paging cycle, a paging offset, etc. In addition, the advanced control station may actively initiate the idle mode in the first area in a manner similar to that of example 7.

After the mobile station enters the idle mode, a paging broadcast message (AAI _ PAG-ADV) is periodically received in the first area according to the assigned paging cycle and paging offset information at the paging listening interval. The paging broadcast message is periodically transmitted by the advanced control station, and contains information indicating the number of mobile stations paged by the advanced control station using the conventional protocol paging identifier and the hash of the MAC address of the mobile station to be transmitted to the mobile station requiring location update or network reentry.

The mobile station judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Preferred embodiment ten

After the mobile station enters the idle mode according to the seventh, eighth and ninth preferred embodiments, the mobile station periodically receives a paging broadcast message (AAI _ PAG-ADV) in the first area according to the assigned paging cycle and paging offset information at the paging listening interval. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If it is a location update, the mobile station transmits a ranging request message (AAI _ RNG-REQ) to the control station, which contains a 24-bit MAC address hash for the control station to recognize the mobile station. Accordingly, the ranging response message (AAI _ RNG-RSP) returned by the control station also includes 24-bit MAC address hash information. After receiving the ranging response message, the mobile station completes the location update and can continue to enter the idle mode.

Description of the preferred embodiment

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. When accessing the advanced control station, the mobile station can obtain the paging identification indication information supported by the advanced control station through a superframe header broadcast and sent by the advanced control station. The paging identification indication is 1 bit, can be indicated independently, and can also be multiplexed with the network access identification type indication, and is used for indicating whether the traditional technology identification or the advanced technology identification is adopted for paging processing. If the indication is marked by the traditional technology, the mobile station uses the MAC address hash to perform paging judgment. If the mobile station is currently accessing the second area of the APC, the mobile station wants to enter the idle mode due to temporary absence of data transmission request or the APC actively initiates entering the idle mode in the second area. The processing thereafter is the same as that in the fourth preferred embodiment, and is not described again here.

Preferred embodiment twelve

According to the seventh and eighth preferred embodiments, the mobile station may enter the idle mode through the first area or may enter the idle mode through the second area, and the mobile station periodically receives a paging broadcast message (AAI _ PAG-ADV or MOB _ PAG-ADV) in the corresponding area according to the allocated paging cycle and paging offset information at the paging listening interval.

If the advanced control station can obtain the information message of the relevant paging group corresponding to the first area or the second area or the information of the mobile station needing to be paged corresponding to the first area or the second area from the paging controller, the advanced control station only contains the information of the mobile station needing to be paged in the area when the advanced control station sends the paging broadcast message in the first area and the second area. If the advanced control station can not obtain the information, the paging broadcast messages sent by the first area and the second area of the advanced control station comprise all the mobile stations needing to be paged.

Different communication areas of the advanced control station are divided into different paging groups, the paging groups belonging to different communication areas can be distinguished by different paging group identifications, for example, the paging groups of a first area and a second area are distinguished by high bits of a paging group identifier, the highest bit of the paging group identifier being 0 represents the paging group formed by the first area of the advanced control station, and the highest bit of the paging group identifier being 1 represents the paging group formed by the second area of the advanced control station and a conventional control station, or vice versa. Paging groups belonging to different communication areas may also be distinguished using different paging cycles. The advanced control station can judge the communication area of the mobile station to be paged according to the paging group identifier and/or paging cycle to which the paged mobile station belongs, and pages the mobile station in the corresponding area.

The mobile station monitors only the area entering the idle mode and judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance.

Thirteen preferred embodiments

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. When the mobile station accesses the advanced control station, the mobile station acquires that the advanced control station only supports the mobile station to carry out idle mode processing in the second area according to the mode of the traditional control station. The information can be obtained through a superframe header broadcast by the advanced control station or obtained through capability negotiation. Fig. 7 is a flowchart illustrating a process of entering an idle mode by a mobile station according to a thirteenth preferred embodiment of the present invention, wherein the process of entering the idle mode by the mobile station comprises the following steps:

step S702, the mobile station is currently accessed to the first area of the advanced control station, and the mobile station hopes to enter an idle mode because there is no data transmission demand temporarily;

step S704, the mobile station determines whether it is currently in the first area, if so, step S706 is executed, otherwise, step S708 is executed;

step S706, the mobile station actively switches from the first area to the second area through area switching;

in step S708, after the ms switches to the second area, the ms actively sends a de-registration request message (DREG-REQ) to the advanced control station in the second area to request to enter the idle mode.

The advanced control station, upon receiving the request, transmits a de-registration command message (DREG-CMD) to the mobile station according to the protocol of the legacy control station. After the mobile station enters the idle mode, a paging broadcast message (MOB _ PAG-ADV) is periodically received in the second area according to the assigned paging cycle and paging offset information at the paging listening interval. The paging broadcast message is periodically transmitted by the advanced control station in the second area, the message including a MAC address hash of the mobile station that needs to be transmitted to the mobile station or that requires a location update. The mobile station judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash information matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. Fig. 8 is a flow chart of a mobile station ending idle mode according to a thirteenth preferred embodiment of the present invention, the mobile station ending idle mode comprising the steps of:

step S802, if the paging message indicates network reentry, the mobile station ends the idle mode to perform network reentry, and in addition, when the mobile station has data to send, the mobile station can perform network reentry at any time to end the idle mode in advance;

step S804, the mobile station starts network access in a second area;

step S806, the mobile station may actively switch from the second area to the first area during the network re-entry in the second area, or the advanced control station may actively initiate to switch the mobile station from the second area to the first area for subsequent communication.

Fourteen preferred embodiments

The mobile station accesses an advanced control station, which is an advanced control station having a first area and a second area, and which is connected to a legacy access network. When the mobile station accesses the advanced control station, the mobile station acquires that the advanced control station only supports the mobile station to carry out idle mode processing in the second area according to the mode of the traditional control station. The information can be obtained through a superframe header broadcast by the advanced control station or obtained through capability negotiation.

The mobile station currently accesses the first zone of the advanced control station, which expects the mobile station to enter an idle mode due to a temporary absence of data transmission requirements, and sends a zone switch message to the mobile station. The mobile station receives the message and then switches from the first area to the second area. After the mobile station switches into the second area handover, the advanced control station transmits a de-registration command message (DREG-CMD) to the mobile station in the second area according to the protocol of the legacy control station. The mobile station transmits a de-registration request message (DREG-REQ) to the advanced control station in the second region, and enters an idle mode.

After the mobile station enters the idle mode, a paging broadcast message (MOB _ PAG-ADV) is periodically received in the second area according to the assigned paging cycle and paging offset information at the paging listening interval. The paging broadcast message is periodically transmitted by the advanced control station in the second area, the message including a MAC address hash of the mobile station that needs to be transmitted to the mobile station or that requires a location update.

The mobile station judges whether to be paged according to whether the received paging broadcast message contains the MAC address hash information matched with the mobile station. If the mobile station is paged, the mobile station performs location update or network re-entry operations according to the indication in the paging message. If the network re-entry is true, the mobile station ends the idle mode. In addition, when the mobile station has data to send, the mobile station can perform network reentry at any time and end the idle mode in advance. The mobile station can be switched to the first area in an active area during the network re-entry process in the second area, and the advanced control station can also be used for actively initiating the switching of the mobile station from the second area to the first area for subsequent communication.

In summary, the embodiments of the present invention can solve the problem of connecting to the conventional access network, so that the idle mode can adapt to the evolution normal operation of the system, thereby achieving the purpose of saving power.
