Abstract: Disclosed are a method and system for assigning a C-RNTI (Cell Radio Network Temporary Identity), aiming to assign the C-RNTI to UE in an aggregation scene of different eNBs by UE. The method comprises the following steps: in the scene that the User Equipment (UE) aggregating the resource of multi-eNBs, the initial access eNB and the target eNB UE aggregated respectively determine the C-RNTI which should be assigned, and then assign the determined C-RNTI respectively to the UE; or, the initial access eNB assigns the specific C-RNTI for bearer separation to UE, wherein the C-RNTI is on a presetting range of the bearer separation specific Radio Network Temporary Identity (RNTI) which is maintained by the eNB UE aggregated.

Abstract: The present disclosure provides an eNB reconfiguration method, a UE and an eNB. The eNB reconfiguration method includes steps of: receiving, by a UE, from an MeNB an RRC reconfiguration message carrying an RRC reconfiguration parameter of an SeNB and an RRC reconfiguration parameter of the MeNB; when the RRC reconfiguration parameter of the MeNB is ignorable, not returning to the MeNB a message, or returning RRC reconfiguration result information of the SeNB to the MeNB; when RRC reconfiguration for the MeNB has been completed, returning to the MeNB an RRC reconfiguration success message carrying the RRC reconfiguration result information of the SeNB; and when an abnormality occurs during the RRC reconfiguration for the MeNB, initiating RRC reconstruction for the MeNB. According to the present disclosure, it is able to process RRC parameter parallel configuration for the SeNB.

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.

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.
