Control apparatus and method for wireless communication system supporting cognitive radio
A control apparatus and method for a wireless communication system supporting cognitive radio. The control apparatus includes an acquisition unit and a management unit. The acquisition unit is configured to acquire information about at least one factor capable of affecting performance of transferring an access request for a frequency spectrum resource by a communication apparatus, the access request being used for making a request to a device which controls the frequency spectrum allocation for allocating a frequency spectrum to the communication apparatus. The management unit is configured to receive the access request sent by the communication apparatus, and optimize a route for the access request of the communication apparatus according to the acquired factor in the case that the access request contains information indicating that the communication apparatus is a slave apparatus of another communication apparatus.
1. A control apparatus in communication with a base station for a wireless communication system, the control apparatus comprising:
a processing circuitry configured to,
receive access requests for spectrum resources from a plurality of communication apparatuses;
merge, based on information transmission performance of the access requests for spectrum resources from the plurality of communication apparatuses, a plurality of access requests into an integration access request, wherein the plurality of access requests corresponds to only some of the received access requests,
transmit the integration access request to a spectrum allocation device, so as to allocate spectrum resources to the plurality of communication apparatuses, and
instruct a first communication apparatus of the plurality of communication apparatuses to change a time configuration of a first access request sent by the first communication apparatus.
2. The control apparatus according to claim 1 , wherein: the plurality of communication apparatus are cognitive radio apparatuses.
3. The control apparatus according to claim 1 , wherein: the integration access request is a single access request.
4. The control apparatus according to claim 3 , wherein: the plurality of communication apparatuses from which the access requests for spectrum resources are received are only some of the radio apparatuses of the system.
5. The control apparatus according to claim 1 , wherein: the plurality of communication apparatuses from which the access requests for spectrum resources are received are only some of the radio apparatuses of the system.
6. The control apparatus according to claim 1 , wherein: the control apparatus is for a wireless communication system supporting cognitive radio, and the plurality of communication apparatus are cognitive radio apparatuses.
7. The control apparatus according to claim 1 , wherein the integration access request comprises geographic location information of the plurality of communication apparatuses.
8. The control apparatus according to claim 1 , wherein the processing circuitry is further configured to,
generate an apparatus parameter of the first communication apparatus of the plurality of communication apparatuses based on a second communication apparatus which the first communication apparatus currently accesses.
9. The control apparatus according to claim 8 , wherein the apparatus parameter comprises routing information corresponding to the second communication apparatus.
10. The control apparatus according to claim 1 , wherein the some of the received access requests merged into the integration access request have a same or a similar period.
