Step 201c: The eNB sets the largest ARP in the cluster group as the ARP corresponding to the cluster group. The second way for step 201 can include the following steps:

The cluster server sends the group identifier of the at least one cluster group to the eNB; the eNB receives the group identifier of the at least one cluster group sent by the cluster server, to obtain the group identifier of the at least one cluster group; and the PCRF is based on the at least one cluster group The service media type acquires the ARP corresponding to the cluster group; the PCRF sends the ARP corresponding to the at least one cluster group to the eNB; the eNB receives the ARP corresponding to the at least one cluster group sent by the PCRF, to obtain the ARP corresponding to the at least one cluster group. , can include the following steps (1) to (7):

Step (1): The cluster server sends a second Rx interface session establishment request message to the PCRF, where the second Rx interface session establishment request message carries at least the group identifier.

When the cluster server establishes a cluster service unicast transmission bearer for the cluster group user equipment, the cluster server sends a second Rx interface session establishment request message to the PCRF, where the second Rx interface session establishment request message carries at least the cluster group user equipment. The group ID of the cluster group in which it is located.

Step (2): The PCRF receives the second Rx interface session establishment request message sent by the cluster server, and obtains the group identity of the cluster group.

Step (3): The PCRF obtains the ARP corresponding to the cluster group according to the service media type of the cluster group corresponding to the group identifier of the cluster group.

The service media types include voice, video, and pictures, and the ARPs of different service media type cluster groups are different.

The step (3) is specifically: the PCRF obtains the service media type of the corresponding cluster group according to the group identifier of the cluster group, and the corresponding relationship between the service media type and the ARP is stored in the PCRF in advance, according to the service media of the cluster group. The type obtains the ARP corresponding to the cluster group corresponding to the service media type from the correspondence between the service media type and the ARP.

Step (4): The PCRF sends a second Gx interface session establishment request message to the gateway function entity, where the second Gx interface session establishment request message carries at least the group identifier and the ARP corresponding to the cluster group; wherein, the gateway function entity in this step It can be a P-GW or an S-GW.

Step (5): The gateway function entity receives the second Gx interface session establishment request message sent by the PCRF, and sends a third bearer resource allocation request message to the MME, where the third bearer resource allocation request message carries at least the group identifier and the cluster group.

Step 202: The eNB establishes a corresponding relationship between the group identifier of the cluster group and the ARP corresponding to the cluster group.

The manner in which the eNB saves the correspondence between the group identifier and the ARP may be in any form. In the embodiment of the present invention, the manner of saving the correspondence between the group identifier and the ARP is not specifically limited. For example, the eNB creates a table and stores the correspondence between the group identifier and the ARP in a table.

Step 203: The MME sends the identifier of the non-cluster group user equipment and the ARP of the non-cluster group user equipment to the eNB.

The step 203 can be implemented in the following first manner or the second manner. For the first mode of step 203, the following steps (1) to (2) are included:

Step (1): The non-cluster group user equipment sends a call request message to the MME, where the call request message carries the identifier of the non-cluster group user equipment;

The identifier of the non-cluster group user equipment is any identifier that can identify the non-cluster group user equipment. In the embodiment of the present invention, the identifier of the non-cluster group user equipment is not specifically limited. For example, the identifier of the non-cluster group user equipment is an IMSI (International Mobile Subscriber Identity) of the non-cluster group user equipment.

Step (2): The MME receives the caller request message sent by the non-cluster group user equipment, and sends a fifth bearer resource allocation request message to the eNB, where the fifth bearer resource allocation request message carries the identifier of the non-cluster group user equipment and ARP of the non-clustered group user equipment;

Specifically, the MME receives the caller request message sent by the non-cluster group user equipment, and acquires the identifier of the non-cluster group user equipment; the MME acquires the ARP of the non-cluster group user equipment according to the identifier of the non-cluster group user equipment, and Sending a fifth bearer resource allocation request message to the eNB, where the fifth bearer The resource allocation request message carries the identifier of the non-cluster group user equipment.

The second mode of step 203 may be:

When the data on the network side is to be sent to the non-cluster group user equipment, the MME obtains the identifier of the non-cluster group user equipment, and obtains the ARP of the non-cluster group user equipment according to the identifier of the non-cluster group user equipment, and sends the fifth The bearer resource allocation request message is sent to the eNB, and the fifth bearer resource allocation request message carries the identifier of the non-cluster group user equipment and the ARP of the non-cluster group user equipment.

Step 204: The eNB receives the identifier of the non-cluster group user equipment sent by the MME and the ARP of the non-cluster group user equipment.

Step 205: The eNB selects a cluster group, and obtains an ARP corresponding to the cluster group according to the group identifier of the selected cluster group.

The corresponding relationship between the group identifier and the ARP is stored in the eNB in advance, and the eNB can obtain the cluster group corresponding to the group identifier of the cluster group from the correspondence between the group identifier and the ARP according to the group identifier of the cluster group. ARP.

The method for selecting an eNB by the eNB is not specifically limited in the embodiment of the present invention. For example, the eNB may randomly select a cluster group, or the eNB selects a cluster group with the lowest priority according to the priority level of the cluster group, or the eNB selects one cluster group according to the order of the cluster group.

Further, the eNB determines whether the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the cluster group. If the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the cluster group, step 206 to step 208; If the ARP of the group user equipment is not greater than the ARP corresponding to the cluster group, go to step 205.

Specifically, the eNB selects a cluster group, and obtains the ARP corresponding to the selected cluster group according to the identifier of the selected cluster group, and determines whether the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the selected cluster group. If the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the selected cluster group, perform step 206 to step 208. If the ARP of the non-cluster group user equipment is not greater than the ARP corresponding to the selected cluster group, reselect a cluster. The group, the reselected cluster group is a cluster group other than the selected cluster group; the eNB obtains the ARP corresponding to the reselected cluster group according to the group identifier of the reselected cluster group, and determines the non-cluster If the ARP of the group user equipment is greater than the ARP corresponding to the reselected cluster group, if the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the reselected cluster group, perform steps 206 to 208; The ARP of the user equipment is not greater than the ARP corresponding to the reselected cluster group. Continue to select. Cluster group, until the ARP of the non-clustered group user equipment is greater than the ARP corresponding to the cluster group. Further, if the ARP of the non-cluster group user equipment is not greater than the corresponding one of the cluster groups

ARP, go to step 209.

Step 206: If the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the cluster group, the eNB releases the bearer resources occupied by all user equipments in the cluster group, and allocates bearer resources for the non-cluster group user equipment.

If the ARP of the non-cluster group user equipment is greater than the ARP corresponding to the cluster group, the eNB will allocate the bearer resources to the non-cluster group user equipment. The bearer resources in the network are limited, and if the bearer resources are all occupied by the trunking communication service, in order to allocate the bearer resources to the non-cluster group user equipment, the bearer resources of the cluster group user equipment can only be preempted. Therefore, the eNB releases The bearer resources occupied by all user equipments in the cluster group, and the bearer resources are allocated to the non-cluster group user equipment.

Step 207: The eNB sends a first response message to the MME, where the first response message is used to indicate that the bearer resource is successfully allocated to the non-cluster group user equipment.

Step 208: The eNB deletes the record of the group identifier that includes the cluster group from the correspondence between the group identifier and the ARP according to the group identifier of the cluster group.

After the bearer resources of all the user equipments of the cluster group are preempted, the eNB deletes the i-records of the group identifiers of the cluster group from the correspondence between the group identifier and the ARP according to the group identifier of the cluster group.

Step 209: If the ARP of the non-cluster group user equipment is not greater than the ARP corresponding to the cluster group, the eNB sends a second response message to the MME, where the second response message is used to indicate that the bearer resource allocation for the non-cluster group user equipment fails.

After receiving the second response message sent by the eNB, the MME forwards the second response message to the non-cluster group user equipment according to the identifier of the non-cluster group user equipment, and the non-cluster group user equipment receives the second response forwarded by the cluster server. The message is started, and the timer is started. After the preset time, the non-cluster group user equipment initiates an active allocation request message to the MME, and proceeds to step 203.

The preset time may be set and changed as needed. In the embodiment of the present invention, the preset time is not specifically limited.

In the embodiment of the present invention, the eNB receives the identifier of the non-cluster group user equipment sent by the MME and the ARP of the non-cluster group user equipment; the eNB selects a cluster group, and acquires the cluster group according to the group identifier of the cluster group. Corresponding ARP; if the ARP of the non-clustered group user equipment is greater than the cluster group The ARP of the group is used to release the bearer resources occupied by all the user equipments in the corresponding cluster group, and the bearer resources are allocated to the non-clustered group user equipment, thereby preventing the bearer resources of one user equipment in the cluster group from being preempted. The unified scheduling and command of the cluster server to the cluster group user equipment ensures the consistency and continuity of the cluster group services. Example 3
