Abstract

The embodiments of the present invention relate to the technical field of communications and provide a data-forwarding method, apparatus and communications system, which realize the veracity and continuity of data transmission during inter-station cell carrier aggregation. The method comprises: a master base station (BS) sending a first message to a subordinate BS, the first message for use to indicate the subordinate BS to perform handover, and the first message including the identification of a target BS; the master BS verifying that the subordinate BS forwards data to the target BS; and the master BS sending a second message to a user equipment (UE), the second message for use to indicate the UE to obtain the data from the target BS. The embodiments of the present invention are used in forwarding data.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data forwarding method, device and communication system. Background technique [0002] With the development of the mobile communication system, the quality of the service provided by the communication system is getting higher and higher. In order to maintain the long-term competitive advantage of 3GPP (the 3rd generation partnership project, the third generation partnership project), LTE-A (LTE-advanced, the follow-up evolution of the long-term evolution system), which is a further evolution of LTE (long term evolution, long-term evolution) technology ) standards development work is in progress. In order to further improve the spectrum efficiency of the communication system and the data throughput of the user, a carrier aggregation (CA, carrier aggregation) technology is introduced into the LTE-A. Carrier aggregation means that a user equipment (user equipment, UE) can simul...
