Abstract

The present application relates to the field of communication technology, and in particular to a base station switching method and system, which are used to solve the problems in the prior art that there are many signaling interactions in the base station switching process, and the switching delay and network overhead are relatively large. The technical solution of this application is based on the architecture of the non-stacked wireless access network, switching the connection network of the mobile terminal from the source base station to the target base station. In this network architecture, the control plane and the data plane are separated, and the control function logic is centralized as a global controller , making the data plane flat. Furthermore, the signaling interaction in the handover process of the base station can be simplified, the handover delay of the base station can be reduced, and the network overhead can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a base station handover method and system. Background technique [0002] In a wireless communication system, when a mobile terminal moves from one cell (referring to the base station or the coverage of the base station) to another cell, in order to ensure that the user does not interrupt the communication, channel switching is required, that is, cell switching. How to successfully and quickly complete the cell handover is one of the keys to the design of the cellular cell system in the wireless communication system. [0003] In traditional Long Term Evolution (LTE) architecture based on X2 interface cell handover, judged by the user test report, if handover is required, the source base station selects a target base station for the mobile terminal to be handed over. After the establishment of the data bearer between the target base station and the source base...
