Embodiment Construction

[0044] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] An RNC at least includes a transceiver module and a processing module.

[0046] The transceiver module is mainly used to send the adjacent cell information of the serving cell under the RNC to other RNCs according to the control of the processing module; and is used to receive the adjacent cell information of the serving cell sent by other RNCs, and send the received information to other RNCs The adjacent cell information of the serving cell is sent to the processing module;

[0047] The processing module is used to control the transceiver module to send the adjacent cell information of the serving cell under this RNC to other RNCs; and update the local adjacent cell information according to the received adjacent cell information of the serving cell under other RNCs.

[0048] Specifically, the processi...

Abstract

The invention provides an RNC and a method for updating local adjacent cell information, and relates to the field of wireless communication. The method of the present invention includes: the first RNC sends the adjacent cell information of the serving cell under the current RNC to the second RNC, and the second RNC updates the local adjacent cell information according to the received adjacent cell information of the serving cell under the first RNC . The technical solution of the invention can update the adjacent cell information between RNCs in time, and send new adjacent cell information in the measurement control message or system message, so that the UE can be switched in time, and the communication continuity of the UE can be effectively guaranteed.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a radio network controller (RNC, RadioNetwork Controller) and a method for updating adjacent cell information. Background technique [0002] It is a basic function of the cellular mobile communication system to ensure the service continuity of mobile users, and the handover of the service cell of the mobile station is the main means to ensure the service continuity. In order to facilitate UE (User Equipment, user equipment) handover, the system needs to configure the adjacency relationship for each cell, so that the adjacent cell information is sent to the UE in the measurement control message, the UE reports the measurement report, and the network side indicates [0003] The UE performs handover. [0004] For example, in the current UTRAN system, the adjacent cell information for each system includes the following: LTE cell, at least including ECGI, PCI, EARFCN (FD...
