Abstract

Embodiments of the present invention provide a data forwarding method, device and communication system, which relate to the communication field and can realize the accuracy and continuity of data transmission during cell carrier aggregation between base stations. The method includes: the primary base station sends a first message to the secondary base station, the first message is used to instruct the secondary base station to perform handover, and the first message includes a target base station identifier; the primary base station confirms that the secondary base station forwards data to the target base station; and the primary base station The base station sends a second message to the user equipment, where the second message is used to instruct the user equipment to obtain the data from the target base station. The embodiment of the present invention is used for data forwarding.

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...
