Abstract

A wireless communication apparatus is adapted to provide a wireless area, and includes an inferencer and a controller. The inferencer is adapted to infer a type of a terminal device that is requesting a new connection, based on information obtained through a previous connection in the wireless area. The controller is adapted to control a communication with the terminal device based on the inferred type.

First claim

What is claimed is:

1 . A wireless communication apparatus adapted to provide a wireless area, comprising:
an inferencer adapted to infer a type of a terminal device that is requesting a new connection, based on information obtained through a previous connection in the wireless area; and a controller adapted to control a communication with the terminal device based on the inferred type.

2 . The wireless communication apparatus according to claim 1 , wherein
the information includes a handover disconnection ratio that is a ratio of a number of connections disconnected due to handovers in the wireless area, to a number of disconnected connections in the wireless area, and the inferencer infers that the terminal device is a machine-to-machine (M2M) device, when the handover disconnection ratio is equal to or less than a first threshold.

3 . The wireless communication apparatus according to claim 2 , wherein
the information includes a round-trip handover ratio that is a ratio of a number of repeated handovers performed between the wireless area and another wireless area, to a number of handovers performed, and the inferencer infers that the terminal device is the machine-to-machine (M2M) device, when the handover disconnection ratio is greater than the first threshold and the round-trip handover ratio is equal to or greater than a second threshold.

4 . The wireless communication apparatus according to claim 1 , wherein
the information includes an average of a data volume communicated through a single connection, for a plurality of connections, and the inferencer infers that the terminal device is the machine-to-machine (M2M) device when the average is equal to or less than a third threshold.

5 . The wireless communication apparatus according to claim 1 , wherein
the information includes an average of a data volume communicated per unit time through a single connection, for a plurality of connections, and the inferencer infers that the terminal device is the machine-to-machine (M2M) device, when the average is equal to or less than a fourth threshold.

6 . The wireless communication apparatus according to claim 1 , wherein
the information includes an average of a ratio of a time duration during which data is communicated through a single connection, to a time duration during which a communication can be carried out through the single connection, for a plurality of connections, and the inferencer infers that the terminal device is the machine-to-machine (M2M) device, when the average is equal to or less than a fifth threshold.

7 . The wireless communication apparatus according to claim 1 , wherein
the inferencer infers that the terminal device is the machine-to-machine (M2M) device, when a cause of the new connection is a delay tolerant access.

8 . The wireless communication apparatus according to claim 1 , wherein
when it is inferred that the terminal device is the machine-to-machine (M2M) device, the controller controls the communication with the terminal device such that at least one of a time duration during which the connection is maintained and a time duration during which the terminal device is operated, becomes shorter than a corresponding time duration when it is inferred that the terminal device is a non-M2M device.

9 . The wireless communication apparatus according to claim 1 , wherein
the information is obtained through connection, a cause of which is a delay tolerant access.

10 . A method of controlling a wireless communication apparatus adapted to provide a wireless area, the method comprising:
inferring a type of a terminal device that is requesting a new connection, based on information obtained through a previous connection in the wireless area; and controlling a communication with the terminal device based on the inferred type.

11 . The method according to claim 10 , wherein
the information includes a handover disconnection ratio that is a ratio of a number of connections disconnected due to handovers in the wireless area, to a number of disconnected connections in the wireless area, and the inferring comprises inferring that the terminal device is a machine-to-machine (M2M) device, when the handover disconnection ratio is equal to or less than a first threshold.

12 . The method according to claim 11 , wherein
the information includes a round-trip handover ratio that is a ratio of a number of repeated handovers performed between the wireless area and another wireless area, to a number of handovers performed, and the inferring comprises inferring that the terminal device is the machine-to-machine (M2M) device, when the handover disconnection ratio is greater than the first threshold and the round-trip handover ratio is equal to or greater than a second threshold.

13 . A wireless communication system comprising:
a wireless communication apparatus adapted to provide a wireless area; a terminal device adapted to wirelessly communicate to the wireless communication apparatus, by being connected with the wireless communication apparatus, in the wireless area; an inferencer adapted to infer a type of the terminal device that is requesting a new connection, based on information obtained through a previous connection in the wireless area; and a controller adapted to control a communication with the terminal device based on the inferred type.

14 . The wireless communication system according to claim 13 , wherein
the information includes a handover disconnection ratio that is a ratio of a number of connections disconnected due to handovers in the wireless area, to a number of disconnected connections in the wireless area, and the inferencer infers that the terminal device is a machine-to-machine (M2M) device, when the handover disconnection ratio is equal to or less than a first threshold.

15 . The wireless communication system according to claim 14 , wherein
the information includes a round-trip handover ratio that is a ratio of a number of repeated handovers performed between the wireless area and another wireless area, to a number of handovers performed, and the inferencer infers that the terminal device is the machine-to-machine (M2M) device, when the handover disconnection ratio is greater than the first threshold and the round-trip handover ratio is equal to or greater than a second threshold.
