The following is a detailed description of the embodiment of the present invention by using the PDS and the MME to send a handover request. FIG. 4 is a schematic flowchart 1 of the implementation process of the base station handover according to the embodiment of the present invention. As shown in FIG. 4, the following steps are included:

Step 401: The UE sends a measurement report to the eNB 1.

The UE determines, according to the policy delivered by the eNB1, that the condition for transmitting the measurement report is met, to the current service. The base station eNB 1 transmits a measurement report carrying signal strength information of the eNB 1 and the base station to which the neighboring cell belongs.

Step 402: The eNB 1 sends a handover request to the PDS and the MME.

The eNB 1 determines that the UE needs to be switched to the eNB 2 according to the pre-configured policy and the measurement report received in step 401. At the same time, the eNB 1 determines that the UE is currently in the cluster service state and the LTE service activation state, that is, the UE uses the cluster service and the LTE service at the same time. And satisfying the condition of the handover to the eNB2, the handover request to the eNB 2 is simultaneously sent to the PDS and the MME; wherein, the MME is a network element in the EPC (corresponding to the LTE service), and the PDS is the network element in the DSS (corresponding to the cluster service) Sending a handover request to the PDS and the MME simultaneously ensures synchronization of the response to the handover request, and improves the success rate of the handover.

Step 403: PDS MME and eNB 2 sends a handover request (Handover Request) transmitted handover request corresponding to ₀ PDS trunking service, the MME sends a handover request to the LTE service.

Step 404: The eNB 2 sends a handover request response to the PDS and the MME.

The eNB2 receives the handover request in step 402, determines that the handover request corresponds to the same UE, and determines the information of the resource allocated for the UE, and carries the information of the resource allocated for the cluster service and the LTE service of the UE in the handover request response, corresponding to Information sent to the PDS and MME; resources allocated for the UE include:

1) General Packet Radio Service Tunneling Protocol (GTP) information for carrying LTE services and cluster services, including a transport layer address and a Tunnel Endpoint IDentity (TEID);

2) GTP tunnel information for causing eNB1 to transmit data to eNB 2;

3) mobility control information and radio resource configuration information, where the mobility control information includes a target cell ID, frequency point information, and access channel information, etc.; the radio resource configuration information includes information of the SRB and the DRB allocated to the UE. In the information of the allocated resources, the mobile 'fi control information and the radio resource configuration information are carried in the handover request response transmitted by the eNB 2 in the form of the RRC protocol connection reconfiguration message.

In addition to the mobility control information and the SRB being the resources shared by the LTE service and the cluster service, other resources, such as GTP information and DRB, need to be allocated separately for different services of the UE. Therefore, the corresponding responses are received in this step. When the service is requested to be handed over, it is necessary to determine whether the handover request corresponds to the same UE, so as to avoid assigning different mobility control information and SRBs for different services of the same UE.

Step 405: The PDS and the MME send a handover command to the eNB 1.

The handover command carries the information of the resource allocated by the eNB 2 to the UE in the step 404, and the mobility control information and the radio resource configuration information are carried in the PDS in this step in the form of the RRC connection reconfiguration message. And the switching command sent by the MME.

Step 406: The eNB 1 sends an RRC connection reconfiguration message to the UE.

The eNB 1 extracts and merges the RRC connection reconfiguration message from the handover command from the PDS and the MME, and sends the merged RRC connection reconfiguration message to the UE, so that the UE performs the handover operation.

Step 407: Status transfer.

The eNB 1 sends the PDCP SN information corresponding to the cluster service to the PDS, and sends the PDCP SN information corresponding to the LTE service to the MME.

Step 408: Status transfer.

The PDS and the MME respectively transmit PDCP SN information to the eNB 2.

After the step 408, the eNB 1 forwards the downlink data that is not sent to the UE in time when the handover is performed, and the uplink data of the acknowledge mode (AM, Acknowledge Mode) that is not delivered in time to the eNB 2, where the data includes the corresponding information of the cluster service.
