Abstract:
1. An allocation apparatus for allocating spectrum resources in wireless networks, comprising: an allocation apparatus transceiver; spectrum utilization information storage means; and spectrum resource coordination means, wherein: said allocation apparatus transceiver is configured to receive and transmit information; said spectrum utilization information storage means is configured to maintain information associated with a current spectrum utilization of at least two wireless networks, wherein said at least two wireless networks share at least part of said spectrum resources and the spectrum utilization of said at least two wireless networks are monitored by a monitoring apparatus, said maintained information associated with said spectrum utilization of at least two of said wireless networks comprising: spectrum resources which are utilized, and spectrum utilization efficiency, channel quality, network load, current quality of service, requirement of service quality, signal to noise ratio, network running status, priority of wireless networks, workable frequency point or frequency range of a wireless network and network type; said spectrum resource coordination means is configured to allocate appropriate spectrum resources to said wireless networks monitored by said monitoring apparatus based on the information associated with said current spectrum utilization of at least two of said wireless networks maintained by said spectrum utilization information storage means, after receiving information associated with a spectrum requirement from said monitoring apparatus in at least one of said wireless networks via said allocation apparatus transceiver, the allocating of appropriate spectrum resources comprising: selecting appropriate spectrum resources to conduct said allocation from spectrum resources that have been allocated to other wireless networks based on the information associated with said spectrum utilization of at least two of said wireless networks maintained by said spectrum utilization information storage means; and said spectrum utilization information storage means updates at least said maintained information associated with said spectrum utilization of said at least two wireless networks monitored by said monitoring apparatus based on the allocation of said spectrum resources by said spectrum resource coordination means, wherein said spectrum resource coordination means sends a reclaim spectrum resource message to said monitoring apparatus in at least one of said other wireless networks via said allocation apparatus transceiver, and selects spectrum resources suitable for allocation or reservation based on a response to said message by said monitoring apparatus that have received said message.
