Communication apparatus and data protecting method of a communication apparatus

Abstract

According to one embodiment, a communication apparatus which performs a wireless communication based on a wireless universal serial bus (USB), includes a monitoring unit configured to monitor a wireless connection situation to and from a partner being in progress of data transfer, and a data protecting unit configured to execute data protection processing to protect the data transmitted and received to and from the partner when the monitoring unit detects a situation in which a wireless connection to the partner is potentially and abnormally disconnected during the data transfer.

Claims

1. A communication apparatus which performs a wireless communication based on a wireless universal serial bus (USB), comprising: a monitoring unit configured to monitor a wireless connection situation to and from a partner being in progress of data transfer; anda data protecting unit configured to execute data protection processing to protect the data transmitted and received to and from the partner when the monitoring unit detects a situation in which a wireless connection to the partner is potentially and abnormally disconnected during the data transfer.

2. The communication apparatus according to claim 1, wherein the data protecting unit outputs a message to notify the fact that there is the situation in which the wireless connection is potentially and abnormally disconnected during the data transfer.

3. The communication apparatus according to claim 1, wherein the data protecting unit queues to suspend processing related to data transfer potentially affected when the wireless connection is abnormally disconnected.

4. The communication apparatus according to claim 3, wherein the data protecting unit releases the suspension by the queuing when the situation, in which the wireless connection is potentially and abnormally disconnected during the data transfer, is eliminated.

5. The communication apparatus according to claim 3, wherein the data protecting unit brings the processing suspended by the queuing into an erroneous completion when the situation, in which the wireless connection is potentially and abnormally disconnected during the data transfer, continues over a fixed period.

6. The communication apparatus according to claim 1, wherein the monitoring unit monitors a received signal strength indication (RSSI).

7. The communication apparatus according to claim 1, wherein the monitoring unit monitors a link quality indication (LQI).

8. A data protecting method of a communication apparatus which performs a wireless communication based on a wireless universal serial bus (USB), comprising; monitoring a wireless connection situation to and from a partner being in progress of data transfer; andexecuting data protection processing to protect data transmitted and received to and from the partner when the monitoring detects a situation in which a wireless connection to the partner is potentially and abnormally disconnected during the data transfer.

9. The data protecting method according to claim 8, wherein the executing data protecting processing outputs a message to notify the fact that there is the situation in which the wireless connection is potentially and abnormally disconnected during the data transfer.

10. The data protecting method according to claim 8, wherein the executing data protection processing queues to suspend processing related to data transfer potentially affected when the wireless connection is abnormally disconnected

11. The data protecting method according to claim 10, wherein the executing data protection processing releases the suspension by the queuing when the situation, in which the wireless connection is potentially and abnormally disconnected during the data transfer, is eliminated.

12. The data protecting method according to claim 10, wherein the executing data protection processing brings the processing suspended by the queuing into an erroneous completion when the situation, in which the wireless connection is potentially and abnormally disconnected during the data transfer, continues over a fixed period.
