Abstract

The invention provides a spectrum resource cooperation access method and system based on geographical location information. The method includes acquiring geographical location information of all acknowledging terminals; selecting a cluster head according to terminal confidence coefficient and the acquired geographical information and clustering all the acknowledging terminals according to the cluster head; acquiring free spectrum information by conducting clustering detection on the acknowledging terminals; conducting access information channel distribution according to the acquired free spectrum information and controlling the acknowledging terminals to conduct spectrum access. By means of the method and system, optimum resource selection can be well achieved, free spectrums are reasonably distributed to necessary acknowledging terminals for access, practicability is good, long-distance transmission errors possibly caused by information transmission of the acknowledging terminals are avoided, system transmission accuracy is improved, and system reliability is improved.

Description

technical field [0001] The present invention relates to the field of cognitive wireless technologies, in particular to a method and system for coordinated access to frequency spectrum resources based on geographic location information. Background technique [0002] With the rapid development of broadband wireless communication technology, under the complex and changeable heterogeneous communication network, it provides fast wireless network access and high-speed data information transmission, ensures high-quality service business level, and realizes convenient and comfortable user experience. become an urgent problem to be solved. In order to solve the above problems, the first thing to solve is the scarcity and low utilization of spectrum. The emergence of cognitive radio (Cognitive Radio) technology has brought people a solution, and it is generally considered to be the best solution to the problem of low utilization of wireless spectrum at present, and it is an important...
