Abstract

The present invention provides a centralized dynamic spectrum management method and system between wireless networks. The spectrum resource is dynamically distributed to a RAT cell according to the spectrum requirement, network gain of the RAT cell, the position information of the base station, the expected maximum emitting power of the base station and relative parameters, and the gain acquired in the dynamic spectrum management is distributed to each RAT in a fairly and reasonable mode. The invention sufficiently utilizes the difference of different wireless system to the spectrum requirement on time and spatial dimension, thereby enhancing the spectrum efficiency and the gain of operator, the dynamic spectrum management is realized in the real communication network by introducing an interference inhibition technology to ensure interference between systems and introducing a cooperation based on market and competition rules to resolve the benefits competing relation between different networks.

Description

technical field [0001] The invention relates to the technical field of wireless communication, more specifically, a centralized dynamic spectrum management method and system using interference suppression technology between wireless networks. Background technique [0002] The continuous emergence of radio access technologies constitutes a wireless communication network pattern in which multiple radio access technologies (Radio Access Technology, RAT) coexist. At the same time, the rapid growth of wireless services and their high-speed and broadband requirements make the spectrum shortage in future wireless communication systems very serious. A traditional spectrum allocation method is a fixed spectrum management method (Fixed Spectrum Management, FSM), that is, spectrum is allocated to different radio access technologies and corresponding operators. However, with the emergence of new wireless access technologies, almost all spectrum suitable for wireless communication trans...
