Base station redundancy device and method

Abstract

The invention provides a base station redundancy switching device and method. The system is composed of a core network, a multi-baseband processing unit and a radio remote unit. The multi-baseband processing unit is composed of same single-baseband processing units; the core network is connected with the plurality of single-baseband processing units in the multi-baseband processing unit; the single-baseband processing units in the multi-baseband processing unit are connected with the radio remote unit; and the single-baseband processing units in the multi-baseband processing unit are connected with one another. The single-baseband processing units in the multi-baseband processing unit can be configured as master or slave units, data is synchronized in real time between the master unit and the slave unit according to redundancy levels, and when the master unit breaks down, the slave unit is upgraded to the master unit, quits the low-power operation mode, and switches a service path. Compared with the prior art, the method and the system have the advantages that the data volume to be switched when the equipment fails can be reduced, so that the data switching time is shortened, and the influence of a user perception problem caused by the equipment failure is reduced.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a base station redundancy switching device and method. Background technique [0002] With the rapid development of communication technology, higher spectrum resources and better air interface communication technology have been applied. As one of the key network elements in the communication system, the base station has higher and higher requirements on its performance and business continuity in some applications such as high-speed rail communication. [0003] At present, the reliability of the base station is usually adopted in an active / standby manner. The usual process is: use the baseband pool, and configure the master-slave role. Under normal communication, the main board is responsible for the business, and the slave board is used as a backup. The main board or a third-party network element detects whether a fault occurs, and if it occurs, data switching is triggere...

AI Technical Summary

Problems solved by technology

[0004] The above method implements data switching only when the system detects a fault, which to a certain extent causes data switching delays, and in some scenarios, the system has no time to switch, that is, the system completely crashes, and the data is too late to switch
