Abstract

The invention provides a mobile communication network expansion communication system and method based on big dipper RDSS (radio data system) system, wherein one or a plurality of big dipper base stations nearly the same as the base station on the current mobile communication network are created, the base station is connected with the mobile communication network through a wire link and is connected with a mobile communication network based on a portable mobile communication base station or a wireless communication network formed by wifi route equipment beyond the signal coverage range of the mobile communication network through a big dipper satellite RDSS wireless short message link, and the two networks are used for realizing the short message communication of mobile equipment (cellphone) beyond the coverage range and the mobile equipment (cellphone) within the coverage range of the mobile communication network so as to expand the coverage range of the mobile communication network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a mobile communication network expansion communication system and method based on the Beidou RDSS system. Background technique [0002] Beidou RDSS system: a satellite system with short message communication function with independent intellectual property rights in my country; [0003] Mobile communication system: a communication system based on the existing digital cellular mobile communication network, such as the communication system of China Mobile, the communication system of China Unicom and the communication system of China Telecom. [0004] At present, my country has built a digital cellular mobile communication network covering the whole country to provide various services, mainly including: voice service, short message service, and data service. Mobile Short Message Service (SMS) is suitable for data transmission in the application of embedded system pro...
