The usable levels b of shared resource groupcs(i) it is counted, terminal and base station according to cooperation, then perception knot of the base station based on terminal
After fruit confirms whether frequency point is available, then to the usable levels b of shared resource groupcs(i) it is counted.According to the terminal of collaborative work
And base station, base station then need to comprehensively consider itself sensing results and terminal sensing results, carry out to the availability of shared resource group
Statistics just confirms that the frequency point is available, to further calculate out shared resource only when two aspects, which perceive frequency point simultaneously, can be used
The usable levels b of groupcs(i)。
3. available shared resource group and its usable levels are reported to location resource allocation center by cognitive nodes.
At this point, whether shared resource group is available can also to be identified using bitmap mode, in addition also need definition corresponding
Field is identified the usable levels of available shared resource group.
4. location resource allocation center counts the availability of shared resource group, each shared resource group is calculated
Average usable levels, and use priority division is carried out according to the average usable levels of each shared resource group.
For location resource allocation center, shared resource group available threshold a is provided with for each shared resource groupmc,
The usable levels of the shared resource that location resource allocation center is reported according to each (1~n) cognitive nodes certainly calculate each shared
The average usable levels b of resource groupmc(i), work as bmc(i)≥amcWhen, then location resource allocation center thinks that this shared resource group can
With, otherwise it is assumed that this shared resource group is unavailable, whereinN is cognition
The quantity of node.
5. available shared resource group and its usable levels and available priority are reported to cognition by location resource allocation center
Database.
Here, available shared resource group also uses bitmap mode to be indicated, and available shared resource group can
It needs in addition to define respective field with value and be identified.So far, the course of work of cognitive system terminates, cognitive database continue with
Lower step.
6. cognitive database is according to the usable levels of the cognitive system precedence information reported and each available shared resource group
It is preferential that the maximum available shared resource group of usable levels is selected to be allocated for using in conjunction with itself decision strategy.
In existing frequency spectrum sharing method, cognitive system when carrying out share spectrum resources application, can according to business demand,
Frequency spectrum resource demand is reported to cognitive database, by cognitive database according to current frequency spectrum resource service condition, cognition system
The website of system is distributed, and correspondingly frequency spectrum resource is used to cognitive system for distribution.When cognitive system obtain from cognitive database it is shared
It, may there are adjacent sites or phase due to the difference of cognitive system self-ability, or with other cognitive system when frequency spectrum resource
The reasons such as the interference in adjacent frequency section cause the frequency spectrum resource applied partly or entirely unavailable.At this point, cognitive system need with
Cognitive database carries out repeatedly negotiating to apply to share spectrum resources, increases the time delay of frequency spectrum application, may will be unable to
Meet the response delay requirement of business.And the present invention provides a kind of frequency spectrum share resource application method, cognitive system is carrying out frequency
Before spectrum resource application, usable spectrum resource is determined by frequency spectrum perception, and use priority is carried out to available frequency spectrum resource and is drawn
Point, enable cognitive database preferentially to distribute the high frequency spectrum resource of use priority and used to cognitive system, avoids cognition system
System application arrive not available frequency spectrum resource, can the use to 230MHz frequency range planned again, can effectively improve frequency spectrum
Efficiency alleviates the contradiction of 230 frequency range frequency spectrum resource supply and demand anxieties.
