Method and system for reconfiguration of cognitive radio system resources

Abstract

The invention provides a method and a system for reconfiguration of cognitive radio system resources. The method includes: obtaining reconfiguration commands by respective reconfiguration modules of different radio communication systems according to received frequency spectrum adjustment instructions, network condition monitoring or negotiations of the reconfiguration modules of the different systems; and transmitting the reconfiguration commands to a base station, and performing the reconfiguration commands by the base station so that resource reconfiguration is realized. By the method and the system for reconfiguration of the cognitive radio system resources, the radio resources are reasonably reconfigured by the aid of the respective reconfiguration modules of the different radio communication systems according to use conditions of frequency spectrum resources in the systems, utilization of the frequency spectrum resources among RATs (radio access technologies) and a main system can be coordinated, and resource utilization rate of each radio communication system and the frequency spectrum utilization rate of the main system like a broadcast television system are increased, so that network load conditions are more balanced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for resource reconfiguration of a cognitive radio system. Background technique [0002] With the continuous advancement of radio technology, a large number of various radio services have emerged, and the spectrum resources that radio services rely on are limited. Facing the continuous increase in people's demand for bandwidth, spectrum resources are showing tension; on the other hand In the traditional fixed spectrum allocation mode, the utilization rate of spectrum resources is not high. [0003] At the same time, with the diversification of system requirements, the coexistence of multiple radio access technologies (Radio Access Technology, RAT) has become the status quo, and because different operators are in different geographical areas, the service distribution between different RATs is different of. [0004] Judging from the current status ...

Problems solved by technology

For example, in a certain area, the Global System for Mobile communication (GSM) and LTE system are deployed at the same time. For a period of time, there are few GSM users and small business traffic, so the load of GSM is low, while the LTE system Concentrated users, heavy business traffic, tight resources, and heavy load on the network side of the LTE system. In this scenario, it is a waste of idle resources in GSM, but the resources are too tight for the LTE system.
