Abstract

To enable an appropriate steaming transfer of audio data in an environment where a plurality of profiles can be operated. In a communication terminal according to an embodiment of the present invention, a short distance wireless communication unit receives a remote controller command transmitted from a head set which is connected with a short distance wireless communication, via the wireless communication. An operation profile determination unit refers to a use status of each profile previously managed by a Bluetooth profile use status management unit when the remote controller command is received and determines whether a predetermined profile used upon the wireless communication is operated. When it is determined that the predetermined profile is operated, a remote controller control unit performs a control such that a response corresponding to the remote controller command is transmitted to the opposite device and the remote controller command is discarded.

Claims

1. A communication terminal capable of communicating with an electronic device via a short distance wireless communication, comprising:

a reception unit configured to receive a remote controller command transmitted from the electronic device and related to a first profile;

a determination unit configured to determine whether a second profile used upon the short distance wireless communication is operated or not based on a use status of each profile managed in advance when the remote controller command is received by the reception unit, the second profile being different from the first profile; and

a control unit configured, in a case in which the determination unit determines that the second profile is operated;

to transmit a response corresponding to the remote controller command and indicating temporary acceptance of the remote controller command to the electronic device,

to hold the remote controller command until the second profile stops operating and

to start operating the first profile according to the held remote controller command after the second profile stops operating, and to discard the held controller command after the second profile stops operating, and to discard the held remote controller command after sending a response corresponding to the held remote controller command to the electronic device.

2. The communication terminal according to claim 1, wherein in the case where it is determined by the determination unit that the second profile is operated, the control unit is further configured to transmit an acceptance response corresponding to the remote controller command to the electronic device after the second profile stops operating.

3. The communication terminal according to claim 1, wherein in a case where it is determined by the determination unit that the second profile is not operated, the control unit is configured to accept the remote controller command, start a transfer processing of audio data, and start the operation of the first profile.

4. The communication terminal according to claim 1, wherein the remote controller command includes at least a command for instructing a reproduction of the media player.

5. The communication terminal according to claim 1, wherein the second profile used upon the wireless communication includes at least a Dial-up Networking profile (DUN) and a Hands Free Profile (HFP).

6. The communication terminal according to claim 1, wherein the first profile is an Advanced Audio Distribution Profile (A2DP).

7. The communication terminal according to claim 6, wherein starting the operation of the first profile comprises starting a streaming operation based on the A2DP.

8. The communication terminal according to claim 1, wherein holding the remote controller command until the second profile stops operating avoids the generation of sound skipping in the electronic device.

9. The communication terminal according to claim 1, wherein the remote controller command comprises a play command.

10. The communication terminal according to claim 1, wherein the remote controller command comprises one of a fast forward command, a rewind command, a forward command, and a backward command.

11. A communication terminal comprising:

a reception unit configured, in a case in which a plurality of profiles including a first profile and a second profile are multi-connected between the communication terminal and an electronic device, to receive a remote controller command that is related to the first profile and is transmitted from the electronic device via a short distance wireless communication;

a determination unit configured, in a case in which the reception unit receives the remote controller command that is related to the first profile, to determine whether the second profile is operated based on a use status of each of the plurality of profiles managed in advance;

a control unit configured, in a case in which the determination unit determines that the second profile is operated, to transmit an acceptance response or a rejection response corresponding to the remote controller command that is related to the first profile to the electronic device, and to discard the remote controller command, and in a case in which the remote controller command is not discarded, to accept the remote controller command, to hold the remote controller command until the second profile stops operating, and to start operating the first profile according to the held remote controller command after the second profile stops operating.
