FIELD: radio engineering, communication.
SUBSTANCE: when transmitting service between the eNB cells, the source determines, according to the RSRP of the UE upperlink in the serving cell and the target cell, whether to transmit the UE service from the serving cell to the target cell; and if the result is positive, obtains UE parameters including the TA UE in the target cell, and transmits UE data and UE parameters to the target eNB, where TA is used to synchronize the upperlink between the target eNB and the UE. The target eNB performs upperlink synchronization with the UE according to the TA to implement the operation of service transmission from the serving cell to the target cell, wherein the UE is not aware of the service transmission.
EFFECT: reduced time of service transmission between cells.
