Patent ID: 8867998

Claim:
A short range wireless communication device comprising: a connection unit that is concurrently connectable with an external connection unit according to a plurality of data communication protocols, each of which defines data communication under a condition that the connection unit connects with the external connection unit via a short range communication line covering a predetermined communication band; and a control unit that controls connection and disconnection of each of the data communication protocols between the connection unit and the external connection unit, and controls a part of the communication band in the short range communication line to be occupied by data communication under a corresponding data communication protocol, wherein the plurality of data communication protocols includes a high priority data communication protocol corresponding to a high priority part of the communication band in the short range communication line and a low priority data communication protocol corresponding to a low priority part of the communication band in the short range communication line, wherein, when a request for concurrently executing data communications under the plurality of data communication protocols is issued, the control unit preserves the high priority part of the communication band in priority to the low priority part of the communication band so that the control unit executes high priority data communication under the high priority data communication protocol in priority to low priority data communication under the low priority data communication protocol; wherein the high priority data communication includes at least one of data communication concerning data corresponding to user manipulation, data communication concerning data representing a notification of incoming call at the external connection unit from an external communication network, and data communication concerning data that is necessary for the external connection unit to connect with the external communication network.
