Off-line Ad-Hoc network communication system, method and construction method under Femto cell architecture

Abstract

The invention provides an off-line Ad-Hoc network communication system, method and a construction method under the Femto cell architecture. The system comprises UE and one or more DMO Femto base stations, and the DMO Femto base stations are formed by standard Femto cell base stations integrated with gateways. The standard Femto cell base stations are used for receiving service requests launched by the UE and sending the requests to the gateways, and the gateways are used for realizing the service. The system can have the functions of voice, video, short message and file download and roaming, switching and other services among terminal base stations under the off-line environment. In addition, the system is flexible and light and convenient to use, applicable to various emergent communication and trunking communication environments, and capable of reducing the system cost, guaranteeing the system reliability and improving user experience.

Description

technical field [0001] The invention relates to the technical field of emergency communication and trunking mobile communication, in particular to an off-network ad hoc network communication system, method and system construction method under the Femto cell architecture. Background technique [0002] The emergency communication system generally refers to the comprehensive use of various communication resources to ensure rescue, emergency assistance and necessary communication when natural or man-made emergencies occur, and when the communication needs of important holidays and important meetings increase sharply. means and methods of communication. Existing emergency communication systems include vehicle emergency communication systems and satellite emergency communication systems. Among them, the vehicle-mounted emergency communication system (such as emergency communication vehicle) has the characteristics of flexible movement, quick activation and large capacity. In rece...

AI Technical Summary

Problems solved by technology

[0004] Although the emergency communication vehicle has the characteristics of quick response and convenient movement, it is not suitable for environments without roads such as remote mountainous areas or post-disaster areas; the construction and maintenance costs of satellite communications that are not affected by terrain and weather changes are high; the same , the cost of the system will be increased correspondingly by adding the off-network direct working mode in the UE, and it is not universal and cannot be applied to emergency scenarios

Therefore, in the face of off-network scenarios, existing technologies generally have the defects of high cost, small communication range and low practicability
