Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Spread spectrum communication fixed side equipment is divided into two components, a base station controller BSC (or central node RNC) and several base stations BTS (or node Node B). The interface between the base station and the base station controller is called Abis interface or IuB interface. Each base station corresponds to one such interface, and multiple base stations have multiple interfaces, and the base stations can communicate with each other through the base station controller. The base station is generally divided into two parts, the baseband processing part and the radio frequency part. Among them, the baseband processing part completes the processing of the digital baseband part and the interface with the base station controller. The radio frequency part completes the up and down conversion of the signal, power a...

Abstract

The invention discloses a kind of frequency extending communication system, which includes base station controller, at least a concentric base band system and several radio frequency system; the concentric base bank system and the base station controller are connected through Abis or Iub interfaces; the concentric base band system includes at least a base band subsystem and clock system, the mentioned clock subsystem provides clock signal to the base band subsystem, the base band subsystem connects with several radio frequency system through inner interfaces. The invention decreases the base station quantity and the interfaces quantity between base station controllers.

Description

technical field [0001] The invention belongs to the communication field, in particular to a spread spectrum communication system. Background technique [0002] The spread spectrum communication system can be divided into many kinds according to different wireless modulation and demodulation technologies, such as IS95 CDMA, cdma2000, WCDMA, TD-SCDMA and so on. Spread spectrum communication fixed side equipment consists of two parts, a base station controller (BSC) or central node (RNC) and several base stations (BTS) or nodes (Node B). The interface between the base station and the base station controller is called Abis interface or IuB interface. There is one such interface between each base station and the base station controller. Multiple base stations have multiple interfaces. The base stations communicate with each other through the base station controller. communication. [0003] In the existing spread spectrum communication system, a base station is responsible for o...
