Abstract
Disclosed are a method, device and system for switching under a bearer separation scenario, which solve the problem that there are no specific implementation solutions when a UE switches among macro eNBs or processing solutions of data transmission during the switching process, aiming at the bearer separation scenario in the existing protocol. The method of the embodiments of the present application comprises: after a source macro eNB determines that there is a need for performing a switching process of a UE, sending a switching request to each spare target macro eNB, the switching request carrying information for indicating that the UE is in a bearer-separated state and information about the local node where the UE is currently located, and/or the bearer information about the UE which is currently on the local node; and selecting a target macro eNB to switch to for the UE from the spare target macro eNBs which return switching request responses, sending the switching commands carried in the switching request responses returned from the switch target macro eNB to the UE, stopping sending data to the UE and stopping receiving data sent from the UE.
