Claim:
1. An interference allocating method, comprising: acquiring or receiving, by a reconfiguration managing node of a secondary system, information on an idle spectrum resource, and information on an overall interference the secondary system is allowed to produce on the idle spectrum resource; and computing, by the reconfiguration managing node according to the information on the overall interference the secondary system is allowed to produce, a transmit power for a secondary user equipment under management of the reconfiguration managing node, wherein the acquiring or receiving, by the reconfiguration managing node, the information on the idle spectrum resource and the information on the overall interference the secondary system is allowed to produce on the idle spectrum resource comprises: acquiring or receiving, by the reconfiguration managing node from a database configured for storing primary user spectrum resource usage information, the information on the idle spectrum resource and the information on the overall interference the secondary system is allowed to produce on the idle spectrum resource, wherein the information on the idle spectrum resource comprises information on an idle spectrum resource of a primary user allowed to be configured for the secondary system within the range of idle spectrum resources expected to be configured for the secondary system, comprising at least one of: a frequency, a bandwidth, an idle duration, coverage edge information, protection band information, an interference tolerance threshold, wherein the method further comprises: computing, by the database according to the interference tolerance threshold of the primary user on the idle spectrum resource and an interference already produced on the coverage edge of the primary user, a further interference tolerable to the primary user; or allocating, by the database according to the interference tolerance threshold of the primary user and/or the further interference tolerable to the primary user, and according to the nature of any secondary system, an overall interference the any secondary system is allowed to produce, wherein the overall interference the any secondary system is allowed to produce accumulates to give the further interference tolerable to the primary user.
