Cognitive radio system resource redistributing method and system

Abstract

The invention discloses a cognitive radio system resource redistributing method and system. The cognitive radio system resource redistributing method is characterized in that a network side obtains load information of an interface from a network element node; and when resources are redistributed and triggered, the network side redistributes the resources according to the load information of the interface. The invention also discloses a cognitive radio system resource redistributing system; and when the resources are redistributed and triggered, the cognitive radio system resource redistributing system redistributes the resources according to the obtained load information of the interface so that the radio resources can be reasonably distributed, the spectrum efficiency is improved, the condition of redistributed radio resource malfunction is avoided, and the success rate of the radio resource redistribution is increased.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for reconfiguring resources of a cognitive radio system. Background technique [0002] With the continuous progress of radio technology, various radio services emerge in large numbers. However, the spectrum resources that radio services rely on are limited. Faced with the increasing demand for bandwidth, the spectrum resources are extremely tense; on the other hand, under the traditional fixed spectrum allocation mode, the utilization rate of spectrum resources is not high. high. [0003] With the diversification of system requirements, the coexistence of multiple radio access technologies (Radio Access Technology, RAT) has become the status quo, and for different operators in different geographical areas, the service distribution between different RATs is different, even A big difference. Judging from the current status and development trend o...

[0005] If the idle frequency resources of the GSM system are allocated to the LTE system, the load of the cells in the LTE system can be alleviated, the capacity of the cells can be increased, and the operation of the GSM system will not be affected, but resource borrowing and allocation can be carried out between systems or within the system For example, when the LTE system load is too high, although the idle resources of other cells or systems are borrowed at this time, the reconfiguration module does not take into account that the core network signaling load is too high, such as the Mobile Management Entity (Mobile Management Entity, MME ) signaling load is high, or other interface loads are too high, when the base station obtains new frequency resources, but at this time the interface load is too high and the service cannot be normally allocated to the terminal, then the resource reconfiguration at this time does not play a role Some effects, and there is a certain waste
