The embodiment of the present invention provides a kind of wireless resource management algorithm adaptive configuring method and controller.
For making goal of the invention of the present invention, feature, advantage can be more obvious and understandable, below willIn conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeGround is described, and obviously, described embodiment is only the present invention's part embodiment, but not all implementsExample. Based on the embodiment in the present invention, those of ordinary skill in the art are not making before creative workPut obtained every other embodiment, all belong to the scope of protection of the invention.
Below a kind of wireless resource management algorithm adaptive configuring method in the embodiment of the present invention is retouchedState, refer to Fig. 1, the wireless resource management algorithm adaptive configuring method in the embodiment of the present invention, comprising:
101, controller detects in the control range of above-mentioned controller whether have at least one first community;
Wherein, above-mentioned the first community is currently need to carry out the community that wireless resource management algorithm is reshuffled.
In the embodiment of the present invention, in the control range of above-mentioned controller, there is at least Liang Ge community.
In the embodiment of the present invention, there are two kinds of implementations:
In one implementation, the wireless resource management algorithm of being initiated by community is reshuffled flow process, works asWhen cell detection occurs to degradation event under excessive or its marginal user performance of present load, this community toController sends wireless resource management algorithm reconfiguration request message, carries out with request controller Dui Gai communityWireless resource management algorithm is reshuffled. Therefore, in this case, whether controller can by detectingReceive wireless resource management algorithm reconfiguration request message determine whether exist at least one above-mentioned firstCommunity, if receive wireless resource management algorithm reconfiguration request message, will send above-mentioned Radio ResourceThe first community is confirmed as in the community of management algorithm reconfiguration request message.
In another kind of implementation, the wireless resource management algorithm of being initiated by controller is reshuffled flow process,When controller detects that existing service performance not meet preset requirement in its control area does not meet default wanting, Jiang Gai confirms as community above-mentioned the first community when Qiu the community, and now, controller can be sent out Xiang Gai communitySend wireless resource management algorithm to reshuffle advice message, so that wireless resource management algorithm weight is carried out in this communityConfiguration is prepared, and certainly, controller also can be set up by Bu Xianggai community transmission wireless resource management algorithm reprovisionView message is not construed as limiting herein.
