Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method and a device for sending and receiving system control messages.
Background
In a mobile communication system, a UE (user equipment) has two basic operation modes: idle mode and connected mode. The UE stays in idle mode at the beginning of power-up, and is distinguished by non-access stratum identifier such as IMSI (international mobile Subscriber Identity), TMSI (temporary Subscriber Identity) or P-TMSI (Packet temporary mobile Subscriber Identity). UTRAN (terrestrial radio access network) does not keep information of idle mode UEs and can only page all UEs in one cell or all UEs at the same paging occasion. When the UE completes RRC (radio resource control) connection setup, the UE transitions from idle mode to connected mode. In the RRC connected mode, there are four states of the UE, which reflect the level of UE connection and which transport channel the UE can use. When the RRC connection is released, the UE transitions from the connected mode to the idle mode.
In the RRC connected mode, the states of the UE are divided into four types: CELL _ DCH state, CELL _ FACH state, CELL _ PCH state, URA _ PCH state. These states define the physical channel classes used by the UE, measurement and mobility management tasks, and actions when a state transition occurs. In the CELL _ DCH state, the system allocates a dedicated channel to the UE for large-flow data transmission; when the activity of the UE is reduced and the amount of transmitted data is obviously reduced, the system can transfer the state of the UE to the CELL _ FACH state. In the CELL _ FACH state, the UE can only use common channels to communicate with the system, the uplink uses RACH (random access channel) and the downlink uses FACH (forward access channel), which is suitable for small amount of data transmission. If the activity of the UE decreases again, the system may change the state of the UE to CELL _ PCH, in which case the UE can only listen to the paging channel and cannot perform any data transmission. The lowest activity state is the URA _ PCH state, in which the UE can only listen to the paging channel. The URA _ PCH state differs from the CELL _ PCH state in that when the UE is in the CELL _ PCH state, it needs to be reported to the UTRAN once if the serving CELL where the UE is currently located changes, whereas in the URA _ PCH state, it needs to be reported only when the serving CELL where the UE is located changes. The operator defines the size of the URA area, and generally comprises several cells.
In the existing communication system, the system control message is transmitted in a mode of MIB + SIB (primary message block + system message block) on BCH (broadcast channel), scheduling information of SIB is contained in MIB or scheduling block, and the MIB is fed with a tag value of SIB at the same time. In order to enable UEs in different environments and with different capabilities in the whole cell to receive the system control message sent by the BCH, the BCH generally employs a fixed lower rate and a fixed transmission format, which makes the transmission efficiency of the BCH very low, and the transmission power of the BCH is high, which affects the downlink capacity of the system to a certain extent. Meanwhile, the BCH rate is low, so that the time for reading the BCH by the UE is long, and the electric energy consumption of the UE is increased; on the other hand, if the UE needs to perform inter-frequency or inter-system measurement in the GAP (GAP), the UE needs to read the system control message of other cells, which requires that the time for reading the system control message by the UE must be shortened.
Reading the MIB when the UE in Idle state, CELL _ FACH state, CELL _ PCH state and URA _ PCH state enters a new CELL, acquiring the label VALUE of the SIB, and storing the label and reading the SIB if the label VALUE of the SIB in the MIB is different from the label VALUE in the VALUE _ TAG stored in the UE. For the UE in FDD (frequency division duplex) and CELL _ DCH state, only the specific UE capable of receiving S-CCPCH (common control physical channel) and DCH (dedicated channel) simultaneously can receive the changed system control message, the changed system control message is a system message change indication sent through FACH (forward access channel), and the UE reads the system control message from BCH after receiving the indication.
Currently, in 3GPP (third generation partnership project), various manufacturers are actively researching 3G Long Term Evolution (LTE) systems, and the purpose of LTE is to provide a low-cost network capable of reducing time delay, increasing user data rate, and improving system capacity and coverage. Only PS domain service is used, and the bearing network is IP bearing. In the LTE system, the UE only has two states of Idle and Active, and there is no FACH channel, so according to the prior art, the UE cannot normally receive the changed system control message in the Active state.

Detailed Description
The core of the invention is that after the system control message changes, the changed system control message is sent to the user equipment UE (in an idle state or an active state) by scheduling channel resources at the network side, and the UE is informed to read the system control message sent by the UE by sending the change indication of the system control message, and the changed system control message is informed to the UE in all states in time. Based on the sending mode of the network side, when the UE selects a new cell, or the UE (in an idle state or an active state) receives the system message change indication information sent by the network side, the location of the system control message may be obtained according to the system broadcast message or the system message change indication information, so that the UE may obtain the changed system control message according to the location information.
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.
Referring to fig. 1, fig. 1 shows an implementation process of a system control message sending method according to the present invention, which includes the following steps:
step 101: and when the system control message is changed, the network side schedules the channel resource to send the changed system control message to the UE.
As known to those skilled in the art, in LTE (long term evolution) systems, there are only two states of a UE: an idle state and an active state. In the invention, no matter for the UE in the idle state or the UE in the active state, when the system control message is changed, the network side schedules the channel resource to send the changed system control message to the UE in the idle state or the active state. Of course, the specific channel resources, transmission methods, transmission contents, and the like used are different. The transmission process of the system control message in different cases will be described in detail later.
Step 102: the network side informs the UE to read the system control message sent by the UE by sending the system control message change indication.
As mentioned above, when the system control message changes, the network side needs to schedule the channel resource to send the changed system control message to the UE in the idle state or the active state. This will be explained in detail below.
First, for the UE in idle state, the network side needs to send a system control message to the UE through a broadcast channel. In order to improve the transmission efficiency of the broadcast channel, the invention classifies the system control messages in advance, and divides the system control messages into two types: a first level system control message and a second level system control message. The specific division can adopt, but is not limited to, the following two modes:
(1) the system control message is divided into: system-level system control messages (i.e., second-level system control messages) and cell-level system control messages (i.e., first-level system control messages). Wherein, the system control message at the system level is shared by all cells in the system, for example, the system message block SIB1, SIB2, SIB13, etc.; the system control messages at the cell level are only valid for this cell, e.g. system message block SIB3, SIB4, etc., which may be different in different cells. Of course, there may be different classification manners according to application requirements, for example, a part of system control messages at the system level are classified into the cell level for transmission.
(2) The system control message is divided into two parts: the first part (i.e. the first level system control message) comprises system messages related to cell selection and reselection and system messages required for cell access; the second part (i.e., the second level system control message) includes: all system control messages except the first level system control message.
In this way, the system control message of the first level and the system control message of the second level are respectively transmitted on the broadcast channel and other channels (such as a multicast channel, a downlink shared channel, a dedicated channel, etc.) besides another broadcast channel, so as to reduce the load of the broadcast channel, reduce the transmission power of the broadcast channel, and increase the downlink capacity of the system.
If the system control message of the second level is sent on a channel other than the broadcast channel, the UE needs to be informed of this channel, i.e. to know on which channel the system control message needs to be read. For this purpose, the invention adds a switch indication parameter in the scheduling information contained in the main message block of the system broadcast message, when the parameter is 'on', the system control message of the second level is sent by other channels except the broadcast channel; when the parameter is off, the system control message of the second level is also sent through the broadcast channel, so that when the UE receives the system control message, the sending mode of the system control message of the second level can be known according to the parameter, and the required system control message is obtained.
After the network side sends the system control message to the UE, the network side also needs to inform the UE that the system control message has changed, and for the UE in an idle state, the network side sends a paging message to the UE through a paging channel, wherein the paging message contains system control message change indication information.
Secondly, for the UE in the activated state, because the UE and the network side have a downlink shared channel for message transmission in the activated state, the invention sends the changed system control message to the UE through the downlink shared channel and informs the UE to read the message. At this time, the system control messages do not need to be classified, but all the changed system control messages are sent to the UE through the downlink shared control channel. For example, the following implementations may be adopted:
(1) the network side schedules resources effective to all the UE on a downlink shared channel, and sends the changed system control message to all the UE in an activated state through the resources; and sending the system control message change indication information to all the UE in the activated state through a control channel of a downlink shared channel.
(2) The network side schedules resources effective to all the UE on a downlink shared channel, and sends the changed system control message to all the UE in an activated state through the resources; and then the system control message change indication information is sent to the single UE in the activated state through the control channel of the downlink shared channel.
(3) The network side schedules the effective resource for single UE on the downlink shared channel, and sends the changed system control message to the UE in the activated state through the resource; and then the system control message change indication information is sent to the UE through a control channel of a downlink shared channel.
(4) The network side reserves the system control message transmission resource on the downlink shared channel, and transmits the changed system control message to all the UE in the activated state or a single UE or part of the UE through the reserved resource; and then the system control message change indication information is sent to all the UEs or a single UE or part of the UEs through a control channel of a downlink shared channel.
The network side sends the changed indication information of the system control message and sends the changed position information of the system control message to the UE, no matter the UE is in an idle state or the UE is in an active state.
Corresponding to the above system control message sending method, the present invention also discloses a system control message receiving method, and fig. 2 shows its implementation flow, which includes the following steps:
step 201: when User Equipment (UE) selects a new cell or the UE receives system message change indication information sent by a network side, the position of a system control message is obtained according to the system broadcast message or the system message change indication information.
In the foregoing description of the method for sending the system control message, whether the UE is in the idle state or the UE is in the active state, when the system control message changes, the network side needs to schedule the channel resource to send the changed system control message to the UE in the idle state or the active state, and notify the UE to read the system control message by sending the system control message change indication. Therefore, for the UE, first, the location where the system control message is located is obtained according to the system message change indication information. When the UE selects a new cell, the UE needs to read the system information of the new cell. Therefore, the UE in this state only needs to read the system broadcast message, and knows the location of the system control message according to the system broadcast message.
Step 202: and the UE reads the position of the system control message to acquire the system control message.
After the UE knows the location information of the system control message, the UE can extract the content of the system control message from the location of the system control message on the corresponding channel according to the information.
The following describes the process of acquiring the system control message by the UE in different states in detail.
1. Procedure for reading system control messages by the UE in idle state:
when the UE is in an idle state, a system paging message is received on a paging channel, the paging message includes tag value information of an MIB (Master message Block), and the MIB includes a tag value. After receiving the paging message, the UE needs to determine whether the MIB has changed system messages according to the paging message, and then determines whether the system messages have changed according to tag values included in the MIB, that is, the tag values are system message change indication information.
The UE reads the label VALUE in the MIB, compares whether the label VALUE is the same as the label stored in the variable VALUE _ TAG, if so, the system control message is not changed, and the UE does not need to read the system broadcast message; if the difference is different or no such IE (entity) is stored in the UE, the TAG VALUE in the MIB needs to be stored in the variable VALUE _ TAG, then the system broadcast message is read, the scheduling information stored in the MIB and the scheduling block in the system broadcast message is determined, and the location of the system control message is determined according to the scheduling information. Then, the corresponding system control message is read to the corresponding position.
When a UE (which may be an idle state UE or an active state UE) selects a new cell, the UE does not need to read the system broadcast message after receiving the system paging message, but directly reads the system broadcast message on a broadcast channel to acquire information in the MIB of the new cell, and if the label value of an SIB (system message block) in the MIB is different from the stored label value, the position of each system control message is acquired according to the MIB and scheduling information in the scheduling block. Then, the corresponding system control message is read to the corresponding position.
Fig. 3 shows a process of acquiring a system control message when a UE selects a new cell in the present invention:
step 301: the UE acquires a BCH (broadcast channel) and receives the MIB of the new cell on the BCH.
Step 302: and acquiring a tag value in the MIB.
Step 303: and comparing the TAG VALUE in the MIB with the TAG VALUE stored in the variable VALUE _ TAG of the UE to judge whether the two VALUEs are the same. If so, go to step 304; if not, or if no such IEs are stored in the UE, proceed to step 305.
Step 304: the UE uses the stored system control messages, that is, the system control messages are not changed, and the UE can still use various originally stored system control messages.
Step 305: the UE stores the TAG VALUE to the variable VALUE TAG.
Step 306: and reading and storing the MIB and the scheduling information in the scheduling block.
Step 307: and judging whether the switch indication parameter in the scheduling information of the MIB is on. If so, go to step 308; otherwise, go to step 309.
As mentioned above, when the network side sends the system control message to the idle UE, the system message may be divided into: the second level system control message and the first level system control message are sent on different channels to reduce the load of the broadcast channel. For this purpose, a switch indication parameter may be added to the scheduling information contained in the main message block of the system broadcast message, and a different value of the parameter may indicate whether or not the system control message is transmitted on another channel. For example, when the switch indication parameter is "on", the system control message indicating the second level is transmitted through a channel other than the broadcast channel; when the switch indication parameter is off, it indicates that the system control message is transmitted only through the broadcast channel. Of course the reverse could be true. Therefore, when the UE reads the scheduling information in the MIB of the broadcast message, the UE needs to determine the value of the switch indication parameter to determine whether it needs to read the system control message on another channel. Specifically, which channel is used by the network side to transmit the system control message at the system level also needs to notify the UE through the scheduling information in the MIB.
Step 308: and the UE acquires the channel where the system control message is located according to the scheduling information in the MIB.
Step 309: and acquiring the position of the system control message in the scheduling information.
Step 310: and reading the system control message from the corresponding position on the corresponding channel according to the position of the system control message in the scheduling information.
For system message blocks that are not supported by the UE, the UE may skip reading of the message block and need not monitor for changes in the message block.
2. Procedure for reading system control messages by the UE in active state:
as mentioned above, in the present invention, for the UE in the active state, the network side sends the changed system control message to the UE through the downlink shared control channel, and notifies the UE to read the message. During specific implementation, the network side sends the changed system control message to all the UEs or a single UE or part of the UEs in the activated state through a downlink shared channel; and sending the system control message change indication information to all the UEs or a single UE or part of the UEs through a control channel of a downlink shared channel.
Therefore, no matter whether the system control message or the system control message change indication information issued by the network side is for all UEs or a single UE, for each UE in an active state, the control channel of the downlink shared channel needs to be read, the system message change indication information and the position of the system control message are acquired, then the downlink shared channel is read, and the system control message is acquired according to the position of the acquired system control message.
Referring to fig. 4, fig. 4 shows a functional block diagram of the system control message transmitting apparatus of the present invention:
the device includes: a system control message extraction module S41, a change indication information generation module S42, a resource scheduling module S43, and a transmission module S44. Wherein,
the system control message extraction module S41 is configured to obtain a changed system control message; the resource scheduling module S43 is configured to allocate, to the network side, channel resources required for sending a message to the user equipment UE; the change indication information generating module S42 is connected to the system control message extracting module S41, and is configured to generate system control message change indication information after the system control message changes; the sending module S44 is connected to the system control message extracting module S41, the change indication information generating module S42, and the resource scheduling module S43, respectively, and configured to send the changed system control message and the generated change indication information of the system control message to the UE through the channel resources allocated to the changed system control message and the generated change indication information of the system control message by the resource scheduling module S43, respectively.
In order to reduce the load of the broadcast channel, a classification module S45 may be further disposed between the system control message extraction module S41 and the resource scheduling module S43, for classifying the system control message into: first level system control messages and second level system control messages, cause the resource scheduling module S43 to allocate the required channel resources to it according to the classification,
for example, the classification module S45 may classify system control messages into cell-level system control messages (i.e., first-level system control messages) and system-level system control messages (i.e., second-level system control messages). Wherein, the system control message of the cell level is only effective for the cell; system control messages at the system level are shared for different cells within the system.
For another example, the classification module S45 may divide the system control message into two parts, where one part (i.e., the first-level system control message) includes the system message related to cell selection and reselection and the system message required for cell access; another part (i.e., second level system control messages) includes: all system control messages except the first level system control message.
Of course, other classification schemes are possible.
Thus, the resource scheduling module S43 can allocate different channel resources for different classes of system control messages according to the classification.
When the system control message is sent to the idle state UE, the resource scheduling module allocates other channel resources except the broadcast channel for the system control message of the second level and allocates the broadcast channel resources for the system control message of the first level; when the system control message change indication information is transmitted to the UE in the idle state, the resource scheduling module S43 allocates a paging channel resource thereto.
When sending the system control message to the active UE, the resource scheduling module S43 allocates the downlink shared channel resource to the active UE.
For the detailed process of sending the changed system control message by the UE in different states, reference may be made to the foregoing description of the method for sending the system control message of the present invention, which is not described herein again.
Referring to fig. 5, fig. 5 shows a functional block diagram of the system control message receiving apparatus of the present invention:
the device is located in the UE and comprises: a change indication information obtaining module S51, a system control message position obtaining module S52 and a system control message extracting module S53 connected in sequence.
The change indication information obtaining module S51 is configured to obtain system message change indication information according to information received by the user equipment UE; the system control message position obtaining module S52 is configured to obtain a position of the system control message according to the system message change indication information; the system control message extraction module S53 is configured to extract a system control message according to a location of the system control message.
When the UE is in the idle state, the change indication information obtaining module S51 reads the paging channel, obtains the system message change indication information, and reads the broadcast channel according to the information, and obtains the location of the system control message; when the UE selects a new cell, the change instruction information obtaining module S51 directly reads the broadcast channel to obtain the location of the system control message; when the UE is in the active state, the change indication information obtaining module S51 reads the control channel of the downlink shared channel, and obtains the location of the system control message.
The detailed process of the UE acquiring the system control message in different states may refer to the foregoing description of the method for receiving the system control message of the present invention, and is not described herein again.
While the present invention has been described with respect to the embodiments, those skilled in the art will appreciate that there are numerous variations and permutations of the present invention without departing from the spirit of the invention, and it is intended that the appended claims cover such variations and modifications as fall within the true spirit of the invention.
