Global system for mobile communication (GSM) network-based spectrum reuse communication system and method

Abstract

The invention discloses a global system for mobile communication (GSM) network-based spectrum reuse communication system. The system mainly overcomes the irrationality of spectrum use in the current GSM network. The implementation mode comprises the following steps of: (1) in the existing GSM network, adding a function entity defined by the standard IEEE1900.4, comprising adding an operator spectrum manager (OSM) and a network reconstruction manager (NRM) in a network sub-system (NSS), adding a radio access network reconstruction controller (RRC) and a radio access network measurement collector (RMC) in a base sub-system (BSS) and adding a terminal reconstruction manager (TRM), a terminal reconstruction controller (TRC) and a terminal measurement collector (TMC) in a mobile terminal system (MS); (2) arranging a new interface connected with the original network on the added entity and arranging a message structure transmitted on the interface; (3) on the basis of the system, planning aspecific communication process of an unauthorized user so that the unauthorized user passes message through each interface to assist the unauthorized user in finishing the use of idle frequency rangein the GSM network. By utilizing the GSM network-based spectrum reuse communication system, the utilization rate of the network spectrum can be improved. The invention further discloses a GSM network-based spectrum reuse communication method.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a tiled reuse system based on the GSM network, which is used for the access of non-local registered users to improve spectrum utilization. Background technique [0002] my country's radio technology has always used the static spectrum allocation method. Communication can only work on the dedicated frequency band assigned to it, that is, the entire spectrum is divided into several frequency bands and allocated to different departments or operators, and the frequency band can only be used by The authorized users belonging to the group can use it, and other unauthorized users cannot access or use the frequency band. In fact, it has been proved by the monitoring of various agencies at home and abroad that there are no or few authorized users to use these fixedly allocated frequency bands for a considerable period of time. band. Among these fixedly allocated frequency ba...

Problems solved by technology

This technology is considered to be the most promising wireless technology, however, new spectrum sharing technologies are usually limited to short-distance communication with transmission power, which limits the capacity and flexibility of the communication system

In addition, the current theory of cognitive technology focuses on the construction of a new cognitive network. Although this solution can solve the problem of spectrum resource shortage to a certain extent, in practical applications, this requires a major modification of the existing communication network. In terms of hardware or software, the cost of loss is huge, and the operability is limited to a certain extent
