Problems solved by technology

[0012] In practical application, the above scheme has the following problems: Since the scheme does not provide a corresponding backup protection scheme, this seriously affects the transmission reliability between the baseband and the radio frequency
Once the link fails, it will lead to serious consequences such as communication interruption
[0013] The main reason for this situation is that the existing technical solutions do not realize the backup protection of the communication link, which seriously reduces the transmission reliability between the baseband and the radio frequency unit

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Based on the CPRI specification, the present invention adopts a single-fiber ring network to form a network for a baseband control unit and a radio frequency unit of a mobile communication base station system. The two channels of IQ data and O&M signaling between the baseband and radio frequency are simultaneously carried on the common physical link according to the CPRI protocol, and are multiplexed through different sub-channels. The downlink data blocks are sent simultaneously through the bidirectional optical channel, and the downlink data is downloaded at the node of each radio frequency unit, and the uplink data blocks are filled in the original position, and sent back to the baseband control unit, thereby realizing backup protection.

Abstract

The present invention discloses mobile base station system and backing up protection method relating to mobile communication technology, to make CPRI interface based mobile base station system reliable transmission between base band control unit and radio frequency unit. The present invention adopts single fiber annular networking to realize CPRI interface transmitting and backing up, base band control unit all transmitting downlink data in two different directional channel, each radio frequency unit node in two channel intercepting said node downlink data and adding node sending base band control unit uplink data, then continue back pass to base band, thereby to realize to up-down going data channel backing up protection, in backing up protected two way data, base band control unit or radio frequency unit selected receiving one preferable data, base band control unit also making time delay correcting to IQ data.

Description

technical field [0001] The invention relates to a mobile communication base station system, in particular to a mobile communication base station system and a backup protection method thereof. Background technique [0002] The Common Public Radio Interface (CPRI for short) is a specification about the internal key interface of a mobile communication radio base station publicly published by a number of industry cooperation companies. The CPRI specification is the industry's first public specification on this key interface, providing a set of common standards for key internal interfaces of base stations. [0003] The CPRI industry cooperation focuses on a design of the base station of the third generation (3rd Generation, referred to as "3G") mobile communication system. The design divides the radio base station into a radio part and a control part by specifying a new interface. This interface is the base station The interior is the only and only point of interconnection power...
