Abstract

Claims (50)

1 . An interference control system for wireless communication, the interference control system comprising:

a control device that is disposed outside a carrier network and that is responsible for (i) calculating an interference amount given by a plurality of interfering devices disposed in the carrier network to an interfered device disposed outside the carrier network and (ii) registering position information of each of the plurality of interfering devices; and

a link-up device disposed in the carrier network, communicatively coupled to the control device, and including a processor, a memory that stores a program to be executed by the processor, and a subscriber database that stores information regarding a position of each of the interfering devices,

wherein the processor executes:

processing of receiving a registration application including an ID of an interfering device of the plurality of interfering devices disposed in the carrier network from the interfering device;

position information generation processing of setting position information that matches information stored in the subscriber database regarding the ID upon receiving the registration application; and

processing of transmitting the position information to the control device for registration.

2 . The interference control system for wireless communication according to claim 1 , wherein

the processor further executes:

processing of receiving a position information inquiry including the ID of the interfering device of the plurality of interfering devices disposed in the carrier network from the interfering device;

DB reference processing of specifying an address stored in the subscriber database regarding the ID upon receiving the position information inquiry;

processing of performing position conversion on the address to acquire converted position information indicating a position of the address; and

processing of returning the converted position information to the interfering device that has issued the position information inquiry,

the registration application includes information regarding the position of the interfering device that has issued the registration application together with the ID, and

the position information generation processing includes processing of, when the information regarding the position included in the registration application matches the converted position information, setting the information regarding the position or the converted position information as the position information.

3 . The interference control system for wireless communication according to claim 2 , wherein

the subscriber database stores information of position correction indicating a deviation between a position of each address and an installation point of the interfering device at each address,

the DB reference processing includes processing of specifying the position correction stored in the subscriber database regarding the ID, and

the converted position information indicates a corrected position in which the position correction is reflected on a reference point of the address.

4 . The interference control system for wireless communication according to claim 2 , wherein

the subscriber database stores information of a position range in each address where the interfering device can be installed,

the DB reference processing includes processing of specifying the position range stored in the subscriber database regarding the ID, and

the converted position information indicates a position of the address and a position range of the address.

5 . The interference control system for wireless communication according to claim 2 , wherein the processing of performing the position conversion includes acquiring latitude and longitude corresponding to the address based on map information to generate the converted position information.

6 . The interference control system for wireless communication according to claim 2 , wherein the processor further executes processing of clearing reference data regarding the interfering device, including the address specified in the DB reference processing, in a case where the registration application is not received within a predetermined waiting time after the returning of the converted position information.

7 . The interference control system for wireless communication according to claim 1 , wherein

the registration application includes GPS information indicating a position of the interfering device acquired by the interfering device using GPS together with the ID, and

the position information generation processing includes processing of, when the GPS information included in the registration application matches information stored in the subscriber database, setting the GPS information as the position information.

8 . The interference control system for wireless communication according to claim 1 , wherein

the control device is disposed in a public network that is distinct from the carrier network, and

the link-up device transmits the position information to the control device via the public network.

9 . The interference control system for wireless communication according to claim 8 , wherein the control device is further responsible for registering position information of a second plurality of interfering devices that are disposed in the public network and that communicate directly with the control device without passing through the link-up device.

10 . The interference control system for wireless communication according to claim 1 , wherein the processor further executes processing of receiving a response indicating whether registration is acceptable from the control device and transmitting the response to the interfering device of the plurality of interfering devices.

11 . An interference control method, the method comprising:

using a control device that is disposed outside a carrier network and that is responsible for (i) calculating an interference amount given by a plurality of interfering devices disposed in the carrier network to an interfered device disposed outside the carrier network and (ii) registering position information of each of the plurality of interfering devices;

receiving, via a link-up device disposed in the carrier network and communicatively coupled to the control device, a registration application from an interfering device of the plurality of interfering devices disposed in the carrier network, the registration application including an ID of the interfering device;

upon receiving the registration application, setting position information that matches information stored in a subscriber database regarding the ID, the subscriber database storing information regarding a position of each of the interfering devices; and

transmitting the position information to the control device for registration.

12 . A link-up device disposed in a carrier network and communicatively coupled to a control device disposed outside the carrier network, the link-up device comprising:

a processor;

a memory that stores a program to be executed by the processor; and

a subscriber database that stores information regarding a position of each of a plurality of interfering devices disposed in the carrier network,

wherein the processor executes:

processing of receiving a registration application including an ID of an interfering device of the plurality of interfering devices disposed in the carrier network from the interfering device;

position information generation processing of setting position information that matches information stored in the subscriber database regarding the ID upon receiving the registration application; and

processing of transmitting the position information to the control device that is disposed outside the carrier network for registration, the control device being responsible for (i) calculating an interference amount given by the plurality of interfering devices disposed in the carrier network to an interfered device disposed outside the carrier network and (ii) registering position information of each of the plurality of interfering devices.

13 . A non-transitory computer readable medium having thereon instructions for causing the processor of the link-up device according to claim 12 to execute:

receiving the registration application;

setting the position information; and

transmitting the position information to the control device for registration.
