Community optimization method and device

Abstract

Provided in an embodiment of the present invention are a cell optimization method and device, the method comprising: a first base station receives a parameter and / or a security algorithm transmitted by a second base station or a mobile management entity (MME); the first base station processes the information communicated with a user equipment (UE) according to the parameter and / or the security algorithm, the first base station being a base station for communicating user-plane data with the UE, and the second base station being a base station for communicating a control-plane signaling with the UE. In the embodiment of the present invention, when the user-plane and control-plane of a UE respectively correspond to a first base station and a second base station, the second base station will transmit an updated parameter and / or security algorithm to the first base station, such that the first base station, the second base station and the UE can synchronously use the same parameter and / or security algorithm, thus enabling the first base station to decrypt the information communicated with the UE.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a cell optimization method and device. Background technique [0002] In the prior art, when a user equipment (User Equipment, UE for short) interacts with a base station, a key needs to be used to encrypt the signaling or data of the interaction. [0003] With the development of the Long Term Evolution (LTE for short), some technologies begin to consider cooperation between base stations to increase the data rate of the UE, for example, to separate the user plane and the control plane of the UE. During the handover process of the UE, the source base station (eNB) carries the UE security capability, encryption algorithm and integrity algorithm used by the source base station side, and parameters such as KeNB*, NCC and other parameters in the handover request message, such as the HandOver Request message. The target eNB directly uses the received KeNB* as...
