Abstract

The present invention relates to a multi-standard hybrid networking transmission system based on a CPRI architecture and a transmission method thereof. The multi-standard hybrid networking transmission system based on a CPRI architecture comprises a first-standard radio equipment controller and a second-standard radio equipment controller connected to the first-standard radio equipment controller; the first-standard radio equipment controller and the second-standard radio equipment controller being respectively connected to corresponding radio equipment. The present invention provides, based on dual standard radio equipment controllers, an independent backup topology structure, such that the two standards are completely independent; the present invention is based on an interactive communication connection between the radio equipment controllers, and communication connections between the radio equipment controllers and radio equipment, such that the present invention can independently map, according to respective characteristics of different standards, IQ data of the different standards to IQ blocks of a CPRI protocol for unified transmission. Thus, the invention realizes hybrid transmission of multi-standard signals.

Description

technical field [0001] The present invention relates to data transmission technology in mobile communication, in particular to a multi-system hybrid networking transmission system and transmission method based on CPRI (CommoPublic Radio Interface: Common Public Radio Interface) architecture. Background technique [0002] With the development of mobile communication, the number of mobile communication users has also increased sharply, and operators have to expand the capacity of the mobile communication system to meet the different communication needs of different users. Nowadays, in some coverage scenarios, mobile operators urgently need to adopt 2G (2-Generation wireless telephone technology) signals, 3G (3rd-Generation) signals, 4G (the 4th Generation mobile communication technology) signals and WLAN (Wireless Local Area Networks) signals at the same time Perform signal coverage. [0003] In the process of implementation, the inventors found that there are at least the fo...
