Main body equipment of emergency mobile communication system

Abstract

The invention provides main equipment of an emergency mobile communication system, the main equipment comprises a core network part, a base station part and an optical transmission part, the core network part completes user management and service bearer establishment and management functions of the emergency mobile communication system and establishes connection with an external network to realize interconnection and intercommunication, and the base station part is responsible for generating a radio frequency signal and transmitting the radio frequency signal to the optical transmission part. The main body equipment comprises a main control unit, a software radio unit, an optical transmission convergence unit and a power supply module, the main control unit is configured with the software radio unit, and the software radio unit is configured with the optical transmission convergence unit; and the optical transmission convergence unit realizes one-to-many forwarding of interface data of the software radio unit and the far-end radio frequency unit.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a main device of an emergency mobile communication system. Background technique [0002] When a man-made or natural disaster occurs, the public mobile communication system is extremely vulnerable and cannot provide services. However, in the post-disaster rescue and rescue work, mobile communication has played a pivotal role and is an indispensable support to ensure the rescue effect. [0003] Therefore, when the local mobile communication infrastructure in the disaster area is damaged and cannot operate normally, it is necessary to rely on emergency communication equipment to quickly build an emergency mobile communication network at the disaster site to meet the emergency communication needs of the disaster area in the first place. [0004] In order to provide emergency communication services, the emergency mobile communication network should include core netw...

AI Technical Summary

Problems solved by technology

[0005] Traditional emergency mobile communication equipment is developed based on public mobile communication system equipment, the core network and base station operate independently, the configuration is cumbersome, and it is inconvenient to transport; the base station uses hardware to realize the adjustment of radio frequency signals, which has poor flexibility; the signal transmission distance of the base station is short, and the service coverage limited range
