Abstract

The invention relates to a multi-type mixed network transmission system and transmission method based on a CPRI architecture. The multi-type mixed network transmission system based on the CPRI architecture comprises a first type near-end machine and a second type near-end machine connected to the first type near-end machine; and the first type near-end machine and the second type near-end machine are respectively connected to corresponding far-end machines. The multi-type mixed network transmission system and transmission method of the invention provide independent backup topology architecture on the basis of double near-end machines to make two systems independent from each other. On the basis of interaction communication connection between near-end machines and communication connection between the near-end machines and the far-end machine, the multi-type mixed network transmission system and transmission method can map independent IQ data of different systems into IQblock of a CPRI protocol to perform unified transmission and thus realize multi-type signal mixed transmission.

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...
