Abstract

While a primary user and a secondary user are possibly co-present, a resource is efficiently allocated to the secondary user, QoS at a fixed level is provided to the secondary user of the carrier that is given a license. Provided is controller 30: including a license determiner 301 that determines whether or not a license is given to a carrier that owns each base station 40 which requests resource allocation; an allocation propriety determiner 302 that determines whether or not it is possible to allocate a resource for a secondary service, based on a used situation of a primary service, and an allocation ratio determiner 303; and an allocation ratio determiner 303 that determines a ratio of resources that are allocated to the base stations 40 that are owned by the carrier which is given the license, based on a prescribed parameter, in a case where the resource allocation is possible.

Claims

1. A controller that controls a used state of a resource for a secondary service, with respect to a carrier that is given a license, according to a used situation of a resource for a primary service that is allocated to an existing user, the controller comprising:

a license determiner that determines whether or not the license is given to the carrier that owns each base station which requests resource allocation;

an allocation propriety determiner that determines whether or not it is possible to allocate a resource for the secondary service, based on the used situation of the resource for the primary service; and

an allocation ratio determiner that determines a ratio of resources that are allocated to base stations that are owned by the carrier which is given the license, based on a prescribed parameter, in a case where the allocation of the resource is possible.

2. The controller of claim 1,

wherein the allocation ratio determiner determines the ratio of resources that are allocated to the base stations, based on a data amount of data of a specific type, of which allocation is requested by each base station.

3. The controller of claim 2,

wherein the data of the specific type is a guaranteed bit rate data.

4. The controller of claim 1,

wherein the allocation ratio determiner determines the ratio of resources that are allocated to the base stations, based on communication results of each base station.

5. The controller of claim 4,

wherein the communication results is information on any one or a combination of a time span for which communication is performed, a day of the week on which the communication is performed, throughput, a number of failures in connection, and an amount of data in each base station.

6. A base station that is owned by the carrier which is given the license, which performs communication with a terminal device, using the resource that is allocated by the controller of claim 1, the base station comprising:

a communication propriety determiner that determines whether or not communication with the controller is possible;

a resource candidate determiner that determines a candidate for a resource that is used for the communication with the terminal device, based in a prescribed priority, in a case where the communication with the controller is impossible;

an allocation propriety determiner that determines whether or not it is possible to allocate the candidate for the resource for the communication with the terminal device based on a communication environment; and

a communicator that performs the communication with the terminal device using the resource that is determined as being allocable.

7. The base station of claim 6,

wherein the resource candidate determiner sets a priority in such a manner that the higher throughput a resource has, the higher priority the resource has.

8. The base station of claim 6,

wherein the resource candidate determiner sets a priority of a resource, based on a communication scheme and throughput of each resource.

9. A system that controls a used state of a resource for a secondary service, with respect to a carrier that is given a license, according to a used situation of a resource for a primary service that is allocated to an existing user, the system comprising:

a repository that stores information; and

a controller that;

determines, by referring to the information stored in the repository, whether or not the license is given to the carrier that owns each base station which requests resource allocation;

determines whether or not it is possible to allocate a resource for the secondary service, based on the used situation of the resource for the primary service; and

determines a ratio of resources that are allocated to base stations that are owned by the carrier which is given the license, based on a prescribed parameter, in a case where the allocation of the resource is possible.

10. The system of claim 9,

wherein the controller determines the ratio of resources that are allocated to the base stations, based on a data amount of data of a specific type, of which allocation is requested by each base station.

11. The system of claim 10,

wherein the data of the specific type is a guaranteed bit rate data.

12. The system of claim 9,

wherein the controller determines the ratio of resources that are allocated to the base stations, based on communication results of each base station.

13. The system of claim 12,

wherein the communication results is information on any one or a combination of a time span for which communication is performed, a day of the week on which the communication is performed, throughput, the number of failures in connection, and an amount of data in each base station.

14. The system of claim 9, further comprising:

a base station which is owned by the carrier which is given the license, and which performs communication with a terminal device, using the resource that is allocated by the controller;

wherein the base station;

determines whether or not communication with the controller is possible;

determines a candidate for a resource that is used for the communication with the terminal device, based in a prescribed priority, in a case where the communication with the controller is impossible;

determines whether or not it is possible to allocate the candidate for the resource for the communication with the terminal device based on a communication environment; and

performs the communication with the terminal device using the resource that is determined as being allocable.

15. The base station of claim 14,

wherein the base station sets a priority in such a manner that a higher priority is set for a resource having a higher throughput.

16. The base station of claim 14,

wherein the base station sets a priority of a resource, based on a communication scheme and throughput of each resource.

17. A method for controlling a used state of a resource for a secondary service, with respect to a carrier that is given a license, according to a used situation of a resource for a primary service that is allocated to an existing user, the method comprising:

determining, by referring to a repository, whether or not the license is given to the carrier that owns each base station which requests resource allocation;

determining, by a controller, whether or not it is possible to allocate a resource for the secondary service, based on the used situation of a resource for the primary service; and

determining, by the controller, a ratio of resources that are allocated to base stations that are owned by the carrier which is given the license, based on a prescribed parameter, in a case where the allocation of the resource is possible.
