Abstract:
1. An allocation method for allocating spectrum resources in wireless networks, comprising: maintaining, within an allocation apparatus, information associated with spectrum utilization of at least two wireless networks, wherein said at least two wireless networks share at least part of said spectrum resources and are monitored by a monitoring apparatus; receiving information associated with spectrum requirements from the monitoring apparatus in at least one of said wireless networks; allocating, in response to said receiving said spectrum requirements, appropriate spectrum resources to said wireless networks monitored by said monitoring apparatus based on said maintained information associated with said spectrum utilization of said at least two of said wireless networks, said allocating appropriate spectrum resources comprising: selecting appropriate spectrum resources to conduct said allocation from spectrum resources that have been allocated to other wireless networks; updating at least said maintained information associated with said spectrum utilization of said wireless networks monitored by said monitoring apparatus based on said allocation; and sending, by said allocating apparatus, a reclaim spectrum resource message to a monitoring apparatus in at least one of said other wireless networks, and selecting spectrum resources suitable for allocation or reservation based on the response to said reclaim spectrum resource message by said monitoring apparatus that has received the message, wherein a packet format used for communicating data within a wireless network is different than a packet format of a data communication sent between the monitoring apparatus at said network and said allocation apparatus, said method further comprising: converting packets associated with a received indication to allocate spectrum resources of a wireless network according to that network's wireless protocol; and wherein said allocation apparatus maintains information associated with said spectrum utilization of at least two of said wireless networks, said information 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 allocation is conducted based on: said priority of wireless networks, said workable frequency point or frequency range of wireless network, said channel quality, said network load, said current quality of service, said requirement of service quality, said signal to noise ratio, said network running status, and said network type.
