The application of the M2M service requires large-scale deployment of M2M terminals in a certain area, and since most M2M services have the characteristics of small data volume, scattered data transmission, frequent data transmission times, and various service types, a large number of M2M terminals simultaneously send access requests. The access request is prone to conflicts, which increases the impact on the GERAN network; and once a large number of M2M services occupy network resources, the existing H2H communication cannot be performed normally. For example, the CS domain channel of the GERAN is an exclusive service channel, and can only be used by one user at a time. Once the M2M service is initiated, the CS domain channel will occupy more or all of the CS domain channels, which will cause the existing H2H communication to fail. Or if the M2M terminal frequently requests access to the CS domain channel, the CS domain channel is frequently allocated and managed, which has a significant impact on the system capacity of the original network. For example, a PS domain channel can only support up to 7 users for simultaneous multiplexing. When a large number of M2M terminals send data, they will occupy more radio resources, affecting the normal operation of existing H2H communications and affecting system capacity.

Example 2:

In the embodiment of the present invention, the M2M service in the cell is used as an example to describe the resource management method of the M2M communication. In the method, the network side allocates the M2M service dedicated channel for the M2M service in the cell unit. Accessing the M2M service dedicated channel, in the embodiment of the present invention, the channel access information of the M2M service dedicated channel needs to be sent to the M2M terminal in the system message or other common channel, and the M2M service dedicated channel is currently occupied. The status or idle status information is sent to the M2M terminal. As shown in FIG. 6, the method specifically includes:

601. When an M2M service is initiated, the M2M terminal initiates access to a BSS (Base Station Subsystem, a base station subsystem, equivalent to an access network) on the network side according to channel access information obtained from a system message or other common channel. The request, that is, the access request may be initiated to the BSS through the allocated M2M service dedicated channel. The access request in the embodiment of the present invention may further indicate information such as the requested M2M service type, the amount of data to be sent, and the like.

602. Generally speaking, multiple M2M terminals may simultaneously initiate an access request in a cell, and after receiving the uplink access request of the M2M terminal, the BSS will firstly access the M2M terminal corresponding to the first normally received access request. As the selected M2M terminal, the uplink channel of the M2M service dedicated channel is assigned to the selected M2M terminal; of course, when the uplink channel is assigned, the selected M2M terminal can be instructed to exit the service immediately after the service data transmission is completed. Or indicating that the selected M2M terminal accesses the information sent by the BSS after the service data transmission is completed. It is assumed that the selected M2M terminal directly exits the service after the service data transmission is completed in the embodiment, and the specific application is as follows.

603. Since the uplink channel has been assigned to the selected M2M terminal, the other M2M terminals in the cell cannot use the M2M service dedicated channel transmission industry at the same time. In order to ensure that other M2M terminals do not initiate useless access requests in this case, the BSS of the embodiment of the present invention needs to send the uplink channel to the other M2M terminals through the downlink channel of the M2M service dedicated channel. Information to instruct other M2M terminals not to send access requests at this time. In this way, the useless access request initiated by the M2M terminal can be reduced, and the amount of access request processing of the BSS can be reduced, and the load of the BSS is reduced.

The other M2M terminals always listen to the downlink of the dedicated channel when the data has not been transmitted, and after receiving the information occupied by the uplink channel, no longer initiate an access request until the selected M2M terminal transmits the service data and the M2M service The uplink channel of the dedicated channel returns to the idle state again, and the M2M terminal in the cell can continue to initiate the access request.

604. After the selected M2M terminal receives the assignment of the M2M service dedicated channel, the service data is sent to the BSS through the uplink channel of the M2M service dedicated channel, and the message for sending the service data is not limited in this embodiment. The message sends service data, and can also send service data by defining a new dedicated message. For example, in the circuit domain, the service data can be sent through the application data message, and in the packet domain, the service data can be sent through the wireless data block. The same applies to the transmission of service data in other embodiments of the present invention.

605. After receiving the service data sent by the selected M2M terminal, the BSS forwards the service data to the core network, so that the M2M terminal completes an M2M communication.

606. The selected M2M terminal in the embodiment of the present invention exits the M2M service dedicated channel by itself after completing the transmission of the service data. After the selected M2M terminal performs the transmission of the service data, the embodiment of the present invention releases the uplink channel of the M2M service dedicated channel.

Of course, if the selected M2M terminal selects the information sent by the downlink listening BSS after the service data transmission is completed, the process needs to determine whether the selected M2M terminal needs to continue listening to the downlink, and will determine The result is sent to the selected M2M terminal; if it is determined that the downlink is not required to be listened to, the M2M terminal directly exits the M2M service dedicated channel after receiving the indication; if it is determined that the downlink needs to be heard, the M2M terminal exits the M2M service after receiving the downlink data. Dedicated channel.

607. Since other M2M terminals are instructed not to initiate an access request in the previous 603 process, In order to ensure that the released M2M service dedicated channel can be utilized, the BSS of the embodiment of the present invention needs to send an uplink channel idle message to the M2M terminal through the downlink channel of the M2M service dedicated channel, indicating that the current uplink channel is not occupied, and needs to send service data. The M2M terminal can send an access request.

After receiving the indication, the M2M terminal that listens to the downlink initiates an access request, and the processing of the specific access request may return to the 601 process for processing.

In the above process, the network side may also send some network side data and/or response messages on the downlink channel, and the M2M terminal obtains the information by listening to the downlink. For example, the network side can send some instruction information, and the M2M can determine the subsequent operation by using the instruction information. For example, the network side can send a frequency indicating when the subsequent service is initiated and initiated, and the M2M terminal stores the information after receiving the information. The service is re-initiated next time according to the service initiation time indicated by the network. The data sent by the network side may be shared by the M2M terminal on the dedicated channel, or may carry an identifier in the data to indicate that it is sent to a certain or a specific type of M2M terminal.

During the foregoing M2M service, if the configuration of the M2M service dedicated channel changes, the BSS may send an indication to the M2M terminal in the downlink channel to indicate that the configuration of the M2M service dedicated channel of the M2M terminal has changed, and the terminal is required. Re-reading the system message, the M2M terminal re-listens the system message to obtain new channel access information, and accesses the newly configured M2M service dedicated channel according to the new channel access information; the BSS can also directly indicate the new M2M on the downlink. The channel access information of the service dedicated channel, the M2M terminal can directly access the new M2M service dedicated channel according to the channel access information.

Before step 601, the network side may always reserve an M2M service dedicated channel for the M2M service, and the access information of the dedicated channel is broadcasted in a public downlink such as a system message. The network side can also establish an M2M service dedicated channel for it and broadcast it in the system message only when the M2M service is initiated. When there is no M2M service for the time being, the network side may also assign the M2M service dedicated channel to the normal H2H service for use. That is, the dedicated channel can be dynamically established.

At the same time, the channel can also be dynamically released during the M2M service. For example, the network side may send an indication on the downlink channel to request an M2M terminal that has not yet sent service data. When the uplink is idle, the response is sent. If no response is received, the service data of all the M2M terminals has been sent. The network side may choose to release the M2M service dedicated channel, so that the M2M service dedicated channel can be used for other services. Provide services.

After the embodiment of the present invention is used, the M2M service dedicated channel is allocated for the M2M service, and the M2M service communication is performed through the M2M service dedicated channel, so that other channels in the network can be provided to the existing H2H communication. Use to ensure that H2H communication is normal; even if a large number of M2M services appear at the same time, it will not preempt other non-M2M service dedicated channels, and H2H communication can be performed through other channels to ensure normal H2H communication.

In actual operation, M2M services are classified into many types, such as M2M services in the power monitoring field, M2M services in the public transportation system, etc. If all M2M terminals in a cell share an M2M service dedicated channel, it may cause different The conflict between the services, the embodiment of the present invention may also allocate multiple M2M service dedicated channels for the M2M service, and the same type of M2M terminal shares the same M2M service dedicated channel; of course, if a certain M2M service is in a cell If there are a large number of M2M terminals, the terminals of the M2M service can be divided into several groups, and the M2M terminals in each group separately share one M2M service dedicated channel. For this reason, the embodiment of the present invention may also be optimized, and the specific optimization scheme may also adopt, but is not limited to, the following solutions:

First, setting the corresponding service type and/or group number in each M2M terminal, and then broadcasting a message to the M2M terminal in the system message through the BSS, where the message carries the M2M service corresponding to each service type and/or group. The channel access information of the dedicated channel, so that each M2M terminal can obtain the corresponding channel access information, and the specific use process can be referred to the corresponding description in FIG. 6.

Second, according to the service characteristic QoS (Quality of Service), the M2M terminal is divided into different groups, and each group is assigned a different M2M service dedicated channel; for example, an M2M service is allocated for a service with a particularly high latency requirement (such as an emergency service). The dedicated channel allocates another M2M service dedicated channel for the M2M service with low delay requirement. This can avoid the situation that the service data with high delay requirement cannot be sent in time due to the low-latency service occupying the channel. The embodiment of the present invention may further divide the M2M terminal sharing the same M2M service dedicated channel into at least two packets, and send a message to the M2M terminal sharing the same M2M service dedicated channel through the BSS to indicate that the M2M service is currently allowed to be accessed. M2M terminal grouping of the dedicated channel; thereby realizing time-divisional access sharing the same M2M service dedicated channel, and alleviating the conflict of the M2M service dedicated channel.

Even if the above solution is adopted, there may be a case where the urgency of the M2M terminal sharing the same M2M service dedicated channel is different. In order to ensure that the M2M service dedicated channel can preferentially provide services for the emergency service, the embodiment of the present invention can share the same The M2M terminal of the M2M service dedicated channel is divided into at least two packets, and a priority is defined for each packet. The BSS needs to perform the following control according to the definition of the priority: the network side broadcasts the priority of the M2M terminal currently occupying the uplink channel in the downlink, When the priority of the packet of the M2M terminal that is currently occupied by the M2M service dedicated channel is smaller than the priority of the M2M terminal that initiates the access request, the M2M terminal that currently occupies the M2M service dedicated channel is sent to the M2M terminal that initiates the access request. Of course, the M2M terminal also needs to save its corresponding priority, and the M2M terminal also needs to perform the following control according to the definition of the priority: The priority of the packet where the M2M terminal currently occupies the M2M service dedicated channel is smaller than the priority needs to be initiated. When the priority of the requested M2M terminal is set, the M2M terminal that needs to initiate the access request initiates an access request on the RACH channel. After the priority-defined scheme is adopted, the M2M service dedicated channel can be allocated to the higher priority M2M terminal as much as possible.

In order to implement the foregoing solution, the embodiment of the present invention needs the BSS to send a message to the M2M terminal that shares the same M2M service dedicated channel, to indicate that the M2M terminal group that is currently allowed to access the M2M service dedicated channel and/or currently occupy the M2M service. The priority of the packet where the M2M terminal of the dedicated channel is uplinked, so that the M2M terminal judges whether to initiate the access request according to the indicated packet and priority.

Example 3:

In the embodiment of the present invention, an M2M service initiated by an M2M terminal in a cell is taken as an example, and a resource management method for M2M communication is specifically described. In the method, the network side does not have an M2M service in advance. The M2M service dedicated channel is allocated. As shown in FIG. 7, the method specifically includes:

701. When an M2M service is initiated, the M2M terminal initiates an access request to the BSS on the network side by using a random access channel (RACH). The access request in the embodiment of the present invention may further indicate the requested M2M service type and location. Information such as the amount of data to be sent.

702. After receiving the access request, the BSS allocates an M2M service dedicated channel for the M2M service.

703. In general, multiple M2M terminals may simultaneously initiate an access request in a cell, and after receiving the uplink access request of the M2M terminal, the BSS will firstly access the M2M terminal corresponding to the first normally received access request. As the selected M2M terminal, the uplink channel of the M2M service dedicated channel is assigned to the selected M2M terminal; of course, when the uplink channel is assigned, the selected M2M terminal can be instructed to exit immediately after the service data transmission is completed. The service, or the selected M2M terminal accesses the information sent by the BSS after the service data transmission is completed. It is assumed that the mode of directly exiting the service after the selected M2M terminal service data transmission is completed in this embodiment, and the specific application is as follows.

At the same time, the BSS sends the channel access information of the M2M service dedicated channel to the M2M terminal in the system message or other common channel.

704. Since the uplink channel has been assigned to the selected M2M terminal, the other M2M terminals in the cell cannot use the M2M service dedicated channel to send service data at the same time, in order to ensure that other M2M terminals are in this case. The BSS of the embodiment of the present invention also needs to send the information occupied by the uplink channel to other M2M terminals on the downlink channel of the M2M service dedicated channel, so as to indicate that other M2M terminals do not need to send the access at the moment. request. In this way, the useless access request initiated by the M2M terminal can be reduced, and the amount of access request processing of the BSS can be reduced, and the load of the BSS is reduced.

After receiving the information that the uplink channel is occupied, the other M2M terminal does not initiate the access request until the selected M2M terminal transmits the service data and the uplink channel of the M2M service dedicated channel returns to the idle state again. The M2M terminal in the cell can continue to initiate an access request to the BSS. 705. After receiving the assignment of the M2M service dedicated channel, the selected M2M terminal sends the service data to the BSS through the uplink channel of the M2M service dedicated channel.

706. After receiving the service data sent by the selected M2M terminal, the BSS forwards the service data to the core network, so that the M2M terminal completes the M2M communication.

707. The selected M2M terminal in the embodiment of the present invention exits the M2M service dedicated channel by itself after completing the transmission of the service data. In order to ensure that the selected M2M terminal can transmit the service data through the M2M service dedicated channel after the completion of the transmission of the service data, the embodiment of the present invention also needs to release the uplink channel of the M2M service dedicated channel.

Of course, if the M2M terminal selected in the 703 process accesses the downlink and listens to the information sent by the BSS after the service data is sent, the process needs to determine whether the selected M2M terminal needs to continue listening to the downlink, and sends the judgment result. If the M2M terminal is determined to not need to listen to the downlink, the M2M terminal directly exits the M2M service dedicated channel after receiving the indication; if it is determined that the downlink is not required to be listened to, the M2M terminal exits the M2M service after receiving the downlink data. channel.

708. The BSS of the embodiment of the present invention needs to pass the downlink channel of the M2M service dedicated channel to the M2M terminal, because the other M2M terminal is instructed not to initiate the access request in the process of the previous 704, in order to ensure that the released M2M service dedicated channel can be utilized. The message that the uplink channel is idle is sent, indicating that the current uplink channel is not occupied, and the M2M terminal that needs to send the service data can send the access request.

The M2M terminal that listens to the downlink receives the indication and then initiates the access request. Since the other M2M terminals obtain the channel access information at this time, the subsequent process can be performed according to the method provided in Embodiment 2.

In the above process, the network side may also send some network side data and/or response messages on the downlink channel, and the M2M terminal obtains the information by listening to the downlink. For example, the network side can send some instruction information, and the M2M can determine the subsequent operation by using the instruction information. For example, the network side can send a frequency indicating when the subsequent service is initiated and initiated, and the M2M terminal stores the information after receiving the information. The service is re-initiated next time according to the service initiation time indicated by the network. Data sent by the network side can be Therefore, it is shared by the M2M terminal on the dedicated channel, and the identifier may also be carried in the data to indicate that it is sent to a certain type or a specific terminal.

Of course, an embodiment in which multiple M2M service dedicated channels are allocated in the same 'h area, the M2M terminal is divided into multiple groups, and the M2M terminal group and the priority group that share the same M2M service dedicated channel are used. The specific implementation provided in 2. The specific implementation scheme provided in Embodiment 2 can be adopted for the dynamic allocation and release of the dedicated channel.

Example 4:

In the embodiment of the present invention, the M2M service in the cell initiates the M2M service as an example, and the resource management method of the M2M communication is specifically described. In the method, the network side allocates an M2M service dedicated channel for the M2M service in a cell unit, where the M2M service is dedicated. The channel includes an M2M service dedicated access channel and an M2M service dedicated traffic channel. In order to ensure that the M2M terminal can access the M2M service dedicated channel, the M2M service dedicated channel needs to be sent in the system message or other common channel in the embodiment of the present invention. The channel access information, and the information that the M2M service dedicated channel is currently in an occupied state or an idle state is sent to the M2M terminal. As shown in FIG. 8, the method specifically includes:

801. When an M2M service is initiated, the M2M terminal initiates an access request to the BSS on the network side according to the dedicated access channel access information obtained from the system message or other common channel, that is, the M2M service dedicated access channel may be adopted. The access request is initiated to the BSS. The access request in the embodiment of the present invention may further indicate information such as the requested M2M service type, the amount of data to be sent, and the like.

802. In general, multiple M2M terminals may simultaneously initiate an access request in a cell, and the BSS receives the first normally received access after receiving the access request of the M2M terminal. Requesting the corresponding M2M terminal as the selected M2M terminal, and assigning the uplink channel of the M2M service dedicated traffic channel to the selected M2M terminal; of course, the selected M2M can be indicated while assigning the uplink channel of the M2M service dedicated channel. The terminal quits the service immediately after the service data is sent, or indicates that the selected M2M terminal accesses the information sent by the BSS after the service data transmission is completed. It is assumed that the mode of directly exiting the service after the selected M2M terminal service data transmission is completed in this embodiment, and the specific application is as follows.

803. The uplink channel of the dedicated service channel of the M2M service has been assigned to the selected M2M terminal, so that other M2M terminals in the cell cannot use the M2M service dedicated service channel to send service data at the same time, in order to ensure The other M2M terminals do not initiate useless access requests in this case. The BSS in the embodiment of the present invention also needs to send the M2M service to other M2M terminals on the downlink channel through the M2M service dedicated access channel and/or the dedicated service channel. The information on the upstream channel of the dedicated traffic channel is occupied to indicate that other M2M terminals are not to send access requests at this time. In this way, the useless access request initiated by the M2M terminal can be reduced, and the amount of access request processing of the BSS can be reduced, and the load of the BSS can be alleviated.

After receiving the information of the uplink channel occupied by the dedicated traffic channel of the M2M service, the other M2M terminal does not initiate the access request until the selected M2M terminal transmits the service data and the uplink channel of the M2M service dedicated service channel is again Returning to the idle state, at this time, the M2M terminal in the small area can continue to initiate an access request to the BSS through the M2M service dedicated access channel.

804. After the selected M2M terminal receives the assignment of the M2M service dedicated channel, the M2M terminal accesses the dedicated channel according to the access information of the dedicated service channel broadcasted in the system message, and sends the service data, and sends the service data message. The patent is not limited, and may be sent by using an existing message or by defining a new dedicated message. For example, in the circuit domain, the service data may be sent through the application data message, and in the packet domain, the service data may be sent through the wireless data block.

805. After receiving the service data sent by the selected M2M terminal, the BSS performs the service. The data is forwarded to the core network, and as a result, the M2M terminal completes an M2M communication.

806. The selected M2M terminal in the embodiment of the present invention exits the M2M service dedicated service channel by itself after completing the transmission of the service data. In order to ensure that the selected M2M terminal can send the service data through the M2M service-specific service channel after the transmission of the service data is completed, the embodiment of the present invention also needs to release the uplink channel of the M2M service-dedicated service channel.

Of course, if the M2M terminal selected in the 802 process accesses the information sent by the BSS after the service data transmission is completed, it is determined in the process whether the selected M2M terminal needs to continue listening to the downlink, and the judgment result is sent. The selected M2M terminal; if it is determined that the downlink is not required to be listened to, the M2M terminal directly exits the M2M service dedicated service channel after receiving the indication; if it is determined that the downlink is not required to be listened to, the M2M terminal exits the M2M service after receiving the downlink service data. Dedicated traffic channel.

807. The BSS of the embodiment of the present invention needs to pass the downlink channel of the dedicated access channel of the M2M service, because the other M2M terminal is instructed not to initiate the access request in the process of the previous 803, in order to ensure that the released M2M service dedicated service channel can be utilized. Sending an uplink channel idle message of the dedicated traffic channel of the M2M service to the M2M terminal, indicating that the uplink channel of the current M2M service dedicated traffic channel is not occupied, and the M2M terminal that needs to send the service data can send the access request.

After receiving the indication, the M2M terminal that listens to the downlink initiates an access request through the M2M service dedicated access channel, and the processing of the specific access request may return to the 801 process for processing.

In the above process, the access information of the M2M dedicated traffic channel can also be directly sent in the downlink of the dedicated access channel, which can reduce the burden of the system message, and the terminal can directly listen to the downlink of the dedicated access channel to obtain the access of the dedicated service channel. information.

In the above process, the network side may also send some network side data and/or response messages on the downlink channel, and the M2M terminal obtains the information by listening to the downlink. For example, the network side can send some instruction information, and the M2M can determine the subsequent operations by using the instruction information. For example, the network side can send a frequency indicating when the subsequent service is initiated and initiated, and the M2M terminal stores the information after receiving the information. The next time, the service is initiated again according to the service initiation time indicated by the network. The data sent by the network side may be shared by the M2M terminal on the dedicated channel, or may carry an identifier in the data to indicate that it is sent to a certain type or a specific terminal.

Before step 801, the network side may always reserve an M2M service dedicated channel for the M2M service, and the access information of the dedicated channel is broadcasted in a public downlink such as a system message. The network side can also establish an M2M service dedicated channel for it and broadcast it in the system message only when the M2M service is initiated. When there is no M2M service for the time being, the network side may also assign the M2M service dedicated channel to the normal H2H service for use. That is, the dedicated channel can be dynamically established.

At the same time, the channel can also be dynamically released during the M2M service. For example, the network side may send an indication on the downlink channel, and request that the M2M terminal that has not yet sent the service data sends a response when the uplink of the M2M service dedicated channel is idle. If no response is received, the service data of all the M2M terminals has been sent. At this time, the network side may choose to release the M2M service dedicated channel, so that the M2M service dedicated channel can provide services for other services.

At the same time, the embodiment can be further optimized. When the dedicated traffic channel is occupied, since the dedicated traffic channel and the dedicated access channel are two different physical channels, even when the dedicated traffic channel is occupied, the service data needs to be transmitted. The terminal can still send an access request on the dedicated access channel. The network side may assign uplinks to the terminals in advance. For example, the terminal that requests the sending of the access request needs to notify the terminal of the size of the service data to be sent, and determines the starting time of the next uplink idle, and carries the initial occupation time. The upstream channel is assigned to the terminal that sends the access request on the access channel. The terminal will start to occupy the uplink when the initial occupation time is reached.

During the foregoing M2M service, if the configuration of the M2M service dedicated channel changes, the BSS may send a message to the M2M terminal in the downlink channel of the M2M service dedicated access channel to indicate the M2M service dedicated channel of the M2M terminal. The configuration changes, the M2M terminal needs the idle state to reacquire the channel access information, and accesses the newly configured M2M service dedicated channel according to the new channel access information; the BSS can also directly indicate the new M2M service dedicated channel on the downlink. Channel access information, the M2M terminal can directly access the new M2M service dedicated channel according to the channel access information. After the embodiment of the present invention is used, an M2M service dedicated channel is allocated for the M2M service, and the dedicated channel includes an M2M service dedicated access channel and an M2M service dedicated service channel, and an access request is initiated by using the M2M service dedicated access channel. The M2M service data is sent through the dedicated service channel of the M2M service, so that other channels in the network can be provided to the existing H2H communication to ensure normal H2H communication; even if a large number of M2M services appear at the same time, It will not preempt other non-M2M service dedicated channels, and can perform H2H communication through other channels to ensure normal H2H communication.

The indication sent to the M2M terminal in the process of the embodiment 803, 807 is sent in the M2M service dedicated access channel, and the above indication may also be sent on the M2M service dedicated service channel.

In the embodiment of the present invention, the dedicated channel for the M2M service is allocated, and in the same manner as in the third embodiment, the M2M service dedicated channel is allocated after receiving the access request through the RACH. Of course, in the case of allocating multiple M2M service dedicated channels in the same cell, dividing the M2M terminal into multiple groups, and sharing the M2M terminal grouping and setting priorities of the same M2M service dedicated channel, the method in Embodiment 2 may be adopted. The specific implementation provided.

In the foregoing Embodiments 1 to 4, if there are at least two M2M terminals transmitting an access request on the same channel, we can generally divide the M2M terminals sharing the same M2M service dedicated channel into at least two packets; In the embodiment of the present invention, at least one frame is allocated for each packet from the channel that initiates the access request, and the M2M terminal in each packet initiates in the allocated frame. Access request. As shown in FIG. 9 , each frame in the figure indicates a packet corresponding to the frame, and different frames of a channel for initiating an access request may be allocated to different groups by using frame indication information, and the M2M terminal is in a frame corresponding to the group to which it belongs. Sending an access request on the number can greatly reduce the collision of a large number of terminals simultaneously sending access requests in the same frame. The manner of grouping may be as described in Embodiment 2, or may be grouped according to a certain algorithm according to a terminal identifier (such as IMSI). The packet information may be indicated by the network by signaling or may be pre-configured. Of course, the manner in which the packet sends the access request can be further optimized, and the high-priority service can be allowed to send the access request more frequently, so as to ensure that the M2M high-priority/emergency service data can be sent in time, as shown in FIG. 10 As shown in the figure, Group1 is a high-priority alarm service. Group2 and Group3 are common services. Therefore, Groupl has more frequent access requests than other groups:

Of course, the manner in which the packet sends the access request can be further optimized, and some frame number resources are reserved for the high-priority service, so that the M2M terminal sends the high-priority/emergency service data, as shown in FIG. The reserved frame number resources, these reserved frame numbers are used to send emergency alarm data for the M2M terminal to send high priority/emergency service data, and the M2M terminal may not be restricted by the above group when transmitting such data.

Example 5

In the embodiment of the present invention, the M2M service in the cell initiates the M2M service as an example, and the resource management method of the M2M communication is specifically described. In the method, the network side allocates the M2M service dedicated channel for the M2M service by using the cell as the unit; The method specifically includes:

1201. After the M2M terminal initiates the M2M service or successfully camps on a new cell, the M2M terminal initiates a registration request to the BSS on the network side, where the registration request may include the terminal identifier, the ID of the currently camped cell, and the like, and the service saves the information. The information is prepared for subsequent access scheduling.

1202. In order to obtain the M2M terminal information that is still in the cell, the M2M terminal and the BSS can perform a periodic heartbeat detection process, so that the BSS can obtain the M2M terminal that is currently active in the cell.

1203. In order to ensure that the M2M terminal can send the service data through the M2M service dedicated channel, the BSS performs polling scheduling on the M2M terminals according to the number of currently active terminals acquired by the 1202 process, and uses the downlink channel of the M2M service dedicated channel. The M2M terminal sends scheduling information, where the scheduling information includes information indicating a time interval for transmitting the service data. Generally, the specific implementation manner is: the scheduling information includes an M2M terminal identifier and a radio block number, and the radio block number indication station The terminal corresponding to the M2M terminal identifier sends the service data in the time interval corresponding to the radio block number; or the scheduling information includes the M2M terminal identifier and the frame number, where The frame number indicates that the terminal corresponding to the M2M terminal identifier sends service data in a time interval corresponding to the frame number.

1204. The M2M terminal listens to the downlink acquisition scheduling information of the M2M service dedicated channel, so as to obtain a time interval for transmitting the service data by itself; when the M2M service is initiated, the service data can be sent to the BSS through the M2M service dedicated channel in the time interval indicated by the scheduling information.

Generally speaking, the timing of initiating M2M services includes but is not limited to the following:

First, when the M2M terminal needs to send the M2M service data, the service initiation may be

Triggered by the M2M terminal.

Second, when receiving the trigger command sent by the BSS, that is, the initiation of the service may also be received.

Triggered by the BSS side.

1205. After receiving the service data sent by the M2M terminal, the BSS forwards the service data to the core network, so that the M2M terminal completes an M2M communication.

Method to realize:

First, the allocated M2M service dedicated channel may be after receiving the access request of the M2M terminal, so that the M2M terminal does not allocate the M2M service dedicated channel when sending the access request, so the receiving unit 133 is The access request received before the M2M service dedicated channel is allocated is: an access request initiated by the M2M terminal through the random access channel.

Second, the allocating the M2M service dedicated channel may be before the access request of the M2M terminal is received, so that the M2M service has allocated the M2M service dedicated channel when the access request is sent, so the receiving unit 133 is allocating The access request received before the M2M service dedicated channel is: an access request initiated by the M2M terminal through the M2M service dedicated channel.

In order to ensure that the selected M2M terminal is occupying the M2M service dedicated channel, the other M2M terminal does not initiate the access request, and the sending unit 134 in the embodiment of the present invention needs to indicate that the current M2M service dedicated channel of other M2M terminals is occupied. status.
