Abstract

An information processing apparatus includes a communication unit, a storage unit, and a control unit. The storage unit is configured to store device information related to a device capable of being communicated with by the communication unit and an identifier that identifies the device information for each finding of the device with the device information and the identifier associated with each other. The device information being generated each time the device is found. The control unit is configured to invalidate the device information in a case where a state is detected in which communication with the device is incapable of being performed via a predetermined communication channel and in a case where the identifier is detected to be not changed from when being stored.

Claims

1. An information processing apparatus, comprising:

a communication unit;

a storage unit configured to store device information related to a device capable of being communicated with by the communication unit and an identifier that identifies the device information for each finding of the device with the device information and the identifier associated with each other, the device information being generated each time the device is found; and

a control unit configured to invalidate the device information in a case where a state is detected in which communication with the device is incapable of being performed via a predetermined communication channel and in a case where the identifier is detected to be not changed from when being stored.

2. The information processing apparatus according to claim 1, wherein

the storage unit stores a time stamp that indicates time when the device is found as the identifier, and

the control unit uses the device information to establish connection with the device via the predetermined communication channel, compares the time stamp associated with the device information used with the time stamp associated with current device information, and invalidates the device information when the time stamps coincide with each other.

3. The information processing apparatus according to claim 1, wherein

the control unit is capable of controlling the communication unit to

transmit a confirmation signal for confirming that the connection with the device is valid to the device at a first time interval, after the connection is established with the device via the predetermined communication channel,

change, in a case where a predetermined event that a state where communication with the device is incapable of being performed is estimated to be caused occurs, a time interval at which the confirmation signal is transmitted from the first time interval to a second time interval shorter than the first time interval, and

destroy the connection with the device, in a case where a response signal to the confirmation signal at the second time interval is not received from the device.

4. The information processing apparatus according to claim 3, wherein

the control unit is capable of controlling the communication unit to change the time interval in a case where data is received from the device via a communication channel other than the predetermined communication channel after the connection with the device is established.

5. The information processing apparatus according to claim 4, wherein

the communication unit is capable of communicating with a relay server that relays communication between the information processing apparatus and the device and manages connection between the information processing apparatus and the device via a communication channel other than the predetermined communication channel, and

the control unit is capable of controlling the communication unit to change the time interval in a case where the data is received from the device via the relay server after the connection with the device is established.

6. The information processing apparatus according to claim 3, wherein

the control unit is capable of controlling the communication unit to change the time interval in a case where a notification signal that is to be periodically received from the device with which the connection is established is not received.

7. The information processing apparatus according to claim 3, wherein

the control unit is capable of controlling the communication unit to transmit the response signal to the confirmation signal to the device, when the confirmation signal is received from the device.

8. An information processing method, comprising:

storing device information related to a device capable of being communicated with by the communication unit and an identifier that identifies the device information for each finding of the device with the device information and the identifier associated with each other, the device information being generated each time the device is found; and

invalidating the device information in a case where a state is detected in which communication with the device is incapable of being performed via a predetermined communication channel and in a case where the identifier is detected to be not changed from when being stored.

9. A program causing an information processing apparatus to execute

storing device information related to a device capable of being communicated with by the communication unit and an identifier that identifies the device information for each finding of the device with the device information and the identifier associated with each other, the device information being generated each time the device is found, and

invalidating the device information in a case where a state is detected in which communication with the device is incapable of being performed via a predetermined communication channel and in a case where the identifier is detected to be not changed from when being stored.
