Abstract

Provided is a wireless base station device capable of allocating radio resources with high accuracy. The wireless base station device includes a radio resource allocation unit that allocates radio resources to a wireless communication device, and a priority setting unit that sets a priority of a frequency for allocating the radio resources by the radio resource allocation unit, depending on an allocation amount of the radio resources for each frequency allocated by the radio resource allocation unit.

First claim

What is claimed is:

1. A wireless base station device comprising:
a radio resource allocation unit that allocates radio resources to a wireless communication device;
a communication unit that communicates data by using the radio resources that are allocated by the radio resource allocation unit; and
a priority setting unit that sets a priority of a frequency for allocating the radio resources by the radio resource allocation unit, according to data on communication history of the radio resources for each frequency allocated by the radio resource allocation unit in a communication history during a past specific time period.

2. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency, according to a data amount of the data for each frequency that is communicated by the communication unit.

3. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency, according to a total time for each frequency in which data is communicated by the communication unit.

4. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency to be higher as a frequency has more allocation amount of the radio resource or data amount communicated by the communication unit, or as a frequency has a longer total time in which data is communicated by the communication unit.

5. The wireless base station device according to claim 1 , further comprising:
a reception unit that receives communication history information regarding another station including information regarding an allocation amount of radio resources for each frequency, a communication data amount for each frequency, or information regarding a total communication time for each frequency by another wireless base station device, wherein
the radio resource allocation unit allocates the radio resources, based on the priority which is set by the priority setting unit and the communication history information regarding another station that is received by the reception unit.

6. The wireless base station device according to claim 1 , wherein
the radio resource allocation unit allocates the radio resources, according to the priority which is set by the priority setting unit, and a usage state of radio resources in a vicinity of the wireless communication device.

7. The wireless base station device according to claim 6 , further comprising:
a reception unit that receives information regarding the usage state of radio resources in the vicinity of the wireless communication device.

8. The wireless base station device according to claim 1 , further comprising:
a storage unit that stores communication history information including information regarding an allocation amount of radio resources for each frequency, a communication data amount for each frequency, or a total communication time for each frequency; and
an updating unit that updates the communication history information, based on an allocation amount of radio resources for each frequency that are allocated by the radio resource allocation unit, an amount of data that is communicated by the communication unit, or a total time in which data is communicated by the communication unit, wherein
the priority setting unit sets the priority of the frequency, based on the communication history information.

9. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency, depending on whether the communication unit communicates data from another wireless communication device to the wireless base station device, or from the wireless base station device to another wireless communication device.

10. The wireless base station device according to claim 9 , further comprising:
a storage unit that stores first communication history information for communicating data from the another wireless communication device to the wireless base station device by the communication unit, and second communication history information for communicating data from the wireless base station device to the another wireless communication device by the communication unit.

11. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency, depending on transmission power applied when the communication unit communicates data.

12. The wireless base station device according to claim 11 , further comprising:
a storage unit that stores communication history information, for each transmission power applied when the communication unit communicates data.

13. The wireless base station device according to claim 1 , wherein
the priority setting unit sets the priority of the frequency, depending on a time zone in which the communication unit communicates data.

14. The wireless base station device according to claim 13 , further comprising:
a storage unit that stores communication history information, for each time zone in which the communication unit communicates data.

15. A radio resource management method in a wireless base station device, the method comprising:
a radio resource allocation step of allocating radio resources of a frequency to a wireless communication device; and
a communication step of communicating data by using the radio resources that are allocated by the radio resource allocation step; and
a priority setting step of setting a priority of a frequency for allocating the radio resources in the radio resource allocation step, depending on data on communication history of the radio resources for each frequency allocated in the radio resource allocation step in a communication history during a past specific time period.

16. A non-transitory storage medium in which a radio resource management program is stored to cause a computer to execute respective steps of the radio resource management method as defined in claim 15 .

17. A wireless base station device comprising:
a radio resource allocation unit that allocates radio resources to a wireless communication device;
a priority setting unit that sets a priority of a frequency for allocating the radio resources by the radio resource allocation unit, according to an allocation amount of the radio resources for each frequency allocated by the radio resource allocation unit; and
a reception unit that receives communication history information regarding another station including information regarding an allocation amount of radio resources for each frequency, a communication data amount for each frequency, or information regarding a total communication time for each frequency by another wireless base station device, wherein
the radio resource allocation unit allocates the radio resources, based on the priority which is set by the priority setting unit and the communication history information regarding another station that is received by the reception unit.

18. A wireless base station device comprising:
a radio resource allocation unit that allocates radio resources to a wireless communication device; and
a priority setting unit that sets a priority of a frequency for allocating the radio resources by the radio resource allocation unit, according to an allocation amount of the radio resources for each frequency allocated by the radio resource allocation unit, the radio resource allocation unit allocates the radio resources, according to the priority which is set by the priority setting unit, and a usage state of radio resources
