Abstract

A reporting method includes: obtaining an address that is assigned to a target device and that is included in a control signal used for a communication with an access point in a plurality of access points; storing identification information in a storage in association with the address of the target device; storing, when receiving report destination information, the report destination information in the storage in association with the address of the target device if identification information reported in association with the report destination information is stored in the storage; referring to the storage when obtaining information of a control signal received by one of the plurality of access points; and reporting, when a source address of the control signal exists in the storage, to a report destination stored in association with the source address that there is an access from the target device.

First claim

What is claimed is:

1 . A non-transitory computer-readable recording medium having stored therein a program for causing a computer that controls a network including a plurality of access points to execute a reporting process, the reporting process comprising:
obtaining an address that is assigned to a target device configured to communicate with one of the plurality of access points and that is included in a control signal used for a communication with the access point; storing identification information in a storage unit in association with the address of the target device; storing, when receiving report destination information used for identifying a report destination for information of the target device, the report destination information in the storage unit in association with the address of the target device when identification information reported in association with the report destination information is stored in the storage unit; referring to the storage unit when obtaining information of a control signal received by one of the plurality of access points; and reporting, when a source address of the control signal exists in the storage unit, to a report destination stored in association with the source address that there is an access from the target device.

2 . The non-transitory computer-readable recording medium according to claim 1 , wherein
the computer has information associating an identifier of an access point and an installation position of the access point for each of the plurality of access points, and wherein the reporting process includes:
obtaining a source address of the control signal together with an identifier of an access point that received the control signal;
identifying an installation position of an access point that received the control signal when the source address of the control signal exists in the storage unit; and
reporting the installation position to a report destination stored in association with the source address of the control signal.

3 . The non-transitory computer-readable recording medium according to claim 2 , wherein
when a connection between a first access point that received a control signal from the target device and the target device is disconnected, the reporting process determines that the target device moved out of a first communication area generated by the first access point and reports to the report destination that the target device moved out of the first communication area, and when it is reported that a second access point receives a different control signal from the target device, the reporting process reports to the report destination that the target device moved to a second communication area generated by the second access point.

4 . The non-transitory computer-readable recording medium according to claim 2 , wherein
the computer is capable of communicating with a wireless controller that obtains an address of the target device from a signal transmitted by using a service set identifier that is used when the target device reports the address of the target device to the computer, the reporting process receives, from the wireless controller, a combination of a fact that a connection request was transmitted to one of the plurality of access points from the address of the target device and an identifier of an access point that received the connection request; and the reporting process determines that the target device is in a communication area formed by an access point that is identified by the identifier in the combination.

5 . A control device comprising:
a processor configured to obtain an address that is assigned to a target device configured to communicate with one of a plurality of access points and that is included in a control signal used for a communication with the access point; and a storage unit configured to store identification information in association with the address of the target device, wherein the processor receives report destination information used for identifying a report destination for information of the target device, the processor stores the report destination information in the storage unit in association with the address of the target device when identification information reported in association with the report destination information is stored in the storage unit, and the processor reports, when a source address of a control signal used for a communication with one of the plurality of access points exists in the storage unit, to a report destination stored in association with the source address that there in an access from the target device.

6 . The control device according to claim 5 , wherein
the processor identifies an installation position of an access point that received the control signal, by using information associating an identifier of the access point and an installation position of the access point, when the source address of the control signal exists in the storage unit, and the processor reports the installation position of the access point that received the control signal to a report destination stored in association with the transmission source address of the control signal.

7 . The control device according to claim 6 , wherein
when a connection between a first access point that received a control signal from the target device and the target device is disconnected, the processor determines that the target device moved out of a first communication area generated by the first access point and reports to the report destination that the target device moved out of the first communication area, and when it is reported that a second access point received a different control signal from the target device, the processor reports to the report destination that the target device moved to a second communication area generated by the second access point.

8 . A reporting method performed by a computer that controls a network including a plurality of access points, the reporting method comprising:
obtaining an address that is assigned to a target device configured to communicate with one of the plurality of access points and that is included in a control signal used for a communication with the access point; storing identification information in a storage unit in association with the address of the target device; storing, when receiving report destination information used for identifying a report destination for information of the target device, the report destination information in the storage unit in association with the address of the target device when identification information reported in association with the report destination information is stored in the storage unit; referring to the storage unit when obtaining information of a control signal received by one of the plurality of access points; and reporting, when a source address of the control signal exists in the storage unit, to a report destination stored in association with the source address that there is an access from the target device.

9 . The reporting method according to claim 8 , wherein
the computer has information associating an identifier of an access point and an installation position of the access point for each of the plurality of access points, and wherein the reporting method includes:
obtaining a source address of the control signal together with an identifier of an access point that received the control signal;
identifying an installation position of an access point that received the control signal when the source address of the control signal exists in the storage unit; and
reporting the installation position to a report destination stored in association with the source address of the control signal.
