Problems solved by technology

[0006]However, the O&M channel of the existing radio remote base station is a static establishment method. Once the network layout structure changes, the ID resource number must be reassigned, and the engineering personnel must On-site reconfiguration
Therefore, the existing O&M channel static establishment method has great limitations

Embodiment Construction

[0037] In the following, the establishment process of the O&M channel of the remote radio base station will be described by taking the serial and ring connection modes between the main equipment of the base station and the remote radio unit as examples.

[0038] Such as Figure 5Shown is the topological structure diagram of the serial connection between the radio remote TD-SCDMA base station main equipment and the RRS. It mainly includes three parts: several baseband units 501, namely BBU0-BBUn, a switching unit 502 and several remote radio frequency units 503, namely RRS0-RRSn. The baseband unit 501 and the switching unit 502 are in the main equipment of the base station, and the main equipment of the base station is connected to the remote radio frequency unit RRS and each remote radio frequency unit RRS through optical fibers. A microcontroller unit (MCU, Micro-Controller Unit) and a Field Programmable Gate Array (FPGA: Field Programmable Gate Array) are installed on the b...

Abstract

This invention provides a method for setting up O&M channel in RF zoom out base stations including: a zoom out RF unit controller initiates the O&M broadcast channel to transmit information to a switch unit, the controller of which analyzes said information to send the O&M channel information to a zoom out RF unit, the controller of which analyzes the channel information to switch it from the broadcast channel to its special channel to transmit confirmed information to an exchange unit, which sends the configured information sent by the baseband unit controller to the zoom out RF unit via the O&M special channel, and the controller of which anlyzes the configured information for related distribution to realize dynamic access of the O&M channel. This invention also provides a packet structure of the channel.

Description

Technical field [0001] The present invention involves the establishment of a communication channel for the operation and maintenance channel of radio frequency pull -up base station. Background technique [0002] The existing time-synchronous code divided into multiple address (TD-SCDMA, Time-Division SynchronizationCode Division-Multiple-ACcess) base station is divided into two processing units: baseband signal processing unit and radio frequency signal processing unit.Under normal circumstances, the baseband signal processing unit and the radio frequency signal processing unit are placed in a cabinet at the same time. The operation and maintenance between the two (O & M, Operation & Maintenance) information is passed by the backplane.Sometimes due to the environmental restrictions, the radio frequency signal processing unit is pulled out of the base station, and it is connected to the baseband signal processing unit in the base station through the optical fiber to form the rad...
