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.

Abstract: Disclosed are an information transmission method and a device thereof. The method comprises: after determining that a UE needs to conduct base station handover, a source base station which supports an eDDA auxiliary information reporting and processing capability querying whether a candidate target base station supports the eDDA auxiliary information reporting and processing capability or not; and if the source base station queries that the candidate target base station supports the eDDA auxiliary information reporting and processing capability or fails to query whether the candidate target base station supports the eDDA auxiliary information reporting and processing capability or not, or when the source base station does not query whether the candidate target base station supports the eDDA auxiliary information reporting and processing capability or not, the source base station sending to the candidate target base station the eDDA auxiliary information about the UE, to enable the candidate target base station which supports the eDDA auxiliary information reporting and processing capability to conduct radio resource parameter configuration on the UE based on the received eDDA auxiliary information about the UE. By using the embodiments of the present invention, during the process of handover a UE from a source base station to a target base station, the efficiency for the target base station which supports an eDDA auxiliary information reporting and processing capability to acquire eDDA auxiliary information about the UE is improved, and the air interface signalling overhead is reduced.

Abstract: The embodiments of this application relate to the field of wireless communications. Disclosed are an auxiliary information reporting and information sending method and device, so that a target base station can acquire the latest auxiliary information of a user equipment (UE) and then can provide the most reasonable configuration for the UE. In this application, the UE reports the auxiliary information to a source base station, and determines whether it is required to re-report the auxiliary information in a target cell; if determining that it is required to re-report the auxiliary information in the target cell, the user equipment reports the auxiliary information to the target base station after being switched to the target cell. It can be seen that, in this solution, the target base station can acquire the latest auxiliary information of the UE, so as to provide the most reasonable configuration for the UE.
