Embodiment Construction

[0056] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0057] The purpose of the present invention is to provide a decision algorithm and switching strategy for RRU switching between redundantly configured BBUs in a star network mode, so as to solve the problem of cell splitting caused by inconsistency of RRU switching and the cell may not work optimally Problems with resource status.

[0058] Such as figure 1 As shown, the RRU group (RRU1-RRU8) is connected to two BBUs (BBU1 and BBU2), and BBU1 and BBU2 are connected to the same BSC through Abis interface 1 and Abis interface 2.

[0059] Configure the RRU group on the BSC as t...

Abstract

The invention provides a method, a base station controller and a base transceiver station. The method includes that the base station controller assembles radio remote units, sets the radio remote units to belong to a main logic cell of a first base band unit, assembles other radio remote units and sets the other radio remote units to belong to secondary logic cells of a second base band unit; and the base station controller determines switching operation among the main logic cell and the secondary logic cells according to resource state information. The method, the base station controller and the base transceiver station have the advantages that the problem of cell splitting due to inconsistency in RRU (radio remote units) is solved, the service quality is improved, and performance indexes are increased.

Description

technical field [0001] The invention relates to a control method of base station equipment in mobile communication equipment, in particular to a method and device for controlling active and standby logic cells under active and standby redundant configuration. Background technique [0002] The Global System for Mobile Communications (GSM, Global System for Mobile Communications, GSM for short) is the most widely used communication system in mobile communications, and its wireless access network equipment is usually called a Base Station Subsystem (BSS for short). [0003] A typical BSS includes two logical nodes: a base station controller (Base Station Controller, BSC for short) and a base transceiver station (Base Transceiver Station, BTS for short). The distributed BTS is composed of RRU (Radio Remote Unit, remote radio unit) and BBU (Base Band Unit, baseband processing unit). In order to ensure the stable operation of the BTS and have a certain disaster recovery capabilit...
