Abstract

The invention discloses a method and device for achieving the long-distance communication of a mobile base station, and relates to the technical field of mobile communication. The method comprises the following steps that a radio frequency board carries out the down conversion of a received radio frequency signal, obtains a digital baseband signal, and transmits the digital baseband signal to a baseband board; the baseband board processes the digital baseband signal into an IQ digital signal which is suitable for microwave transmission, and transmits the IQ digital signal to a microwave board; the microwave board enables the IQ digital signal transmitted by the baseband board to be processed into a microwave signal and transmits the microwave signal to a core network so that the core network carries out the corresponding processing. Through the integrated design of the baseband signal, the method enables equipment to be close to an antenna, reduces the feed loss, improves the coverage capability, improves the networking flexibility, improves the service quality, and greatly reduces the network cost and maintenance cost of a service provider.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for realizing long-distance communication of a mobile base station. Background technique [0002] At present, most 3G / 4G base stations use RRU (Radio Remote Unit, remote radio module) + BBU (Building Base band Unit, indoor baseband processing unit) to form a wireless access network, which is connected to the network through a transmission network composed of optical fiber or microwave. The networking mode of the core network. For places where wired transmission resources are difficult to reach, such as remote villages, islands, and highways, if the traditional networking method is still used, due to the large number of physical interfaces and poor connection stability, the stability and reliability of the entire network will be poor. Subscribers have poor mobile service. Contents of the invention [0003] The purpose of the present invention is to provi...
