9. The base station according to claim 1 , wherein the processor is further configured to execute the instructions to transmit service indication information of the user equipment in a serving base station to a target secondary base station of the user equipment before handover.

10. A base station serving as a target secondary base station, comprising:

a memory that stores a plurality of instructions; and

a processor coupled to the memory and configured to execute the instructions to:

receive identification indication information of user equipment which is served in both a source primary base station and a source secondary base station before handover transmitted by a target primary base station of the user equipment,

wherein the identification indication information includes an identifier of the user equipment in the source secondary base station.

11. The base station according to claim 10 , wherein the processor is further configured to execute the instructions to:

generate an identifier of the user equipment in a joint service mode with the target primary base station; and

transmit the identifier of the user equipment in the joint service mode with the target primary base station generated by the base station to the target primary base station of the user equipment.

12. The base station according to claim 10 , wherein the processor is further configured to execute the instructions to:

receive an identifier of the user equipment in a joint service mode with the target primary base station generated by the target primary base station from the target primary base station.
