Method, device, and computer program for audio routing in wireless communication system, and recording medium therefor
The present disclosure relates to audio routing in a wireless communication system. A method by which a first device performs audio routing in a wireless communication system, according to one embodiment of the present disclosure, comprises the steps of: transmitting audio routing basic information to a second device; receiving an audio routing modification request from the second device; and transmitting, to the second device, audio-routing-related information modified on the basis of the audio routing modification request, wherein the audio routing basic information may comprise at least one of available audio routing device information, set audio routing device information, and audio routing content type information.
1. A method for performing audio routing of an active audio by a first device in a wireless communication system, the method comprising:
transmitting audio routing basic information about the active audio to a second device;
receiving an audio routing modification request from the second device; and
transmitting modified audio routing-related information to the second device based on the audio routing modification request,
wherein the audio routing basic information includes available audio routing device information, configured audio routing list information, and audio routing content type information,
wherein the modified audio routing-related information includes updated configured audio routing list information,
wherein the configured audio routing list information includes at least one input device identifier and at least one output device identifier associated with each audio route of the configured audio routing list information,
wherein the audio routing content type information includes at least one content type associated with each audio route of the configured audio routing list information, and
wherein the at least one content type includes a phone call, and a media playback.
2. The method of claim 1 , wherein:
the available audio routing device information includes at least one of a device identifier list, input characteristics information, or friendly name information.
3. The method of claim 1 , wherein:
the audio routing modification request includes an audio routing modification target based on audio routing basic information.
4. The method of claim 3 , wherein:
the audio routing modification target includes at least one of an output audio routing device identifier, or an input audio routing device identifier.
5. The method of claim 1 , wherein:
the audio routing modification request is included in a write request message for the audio routing basic information maintained in the first device.
6. The method of claim 1 , wherein:
the audio routing basic information is transmitted from the first device to the second device based on a request of the second device or by a notification of the first device without the request of the second device.
7. The method of claim 1 , wherein:
the first device is a server, and the second device is a client.
8. The method of claim 1 , wherein:
the first device and the second device include Bluetooth low energy (BLE) protocol stack.
9. A method for performing audio routing of an active audio by a second device in a wireless communication system, the method comprising:
receiving, from a first device, audio routing basic information about the active audio;
transmitting, to the first device, an audio routing modification request based on the audio routing basic information; and
receiving, from the first device, modified audio routing-related information,
wherein the audio routing basic information includes available audio routing device information, configured audio routing list information, and audio routing content type information,
wherein the configured audio routing list information includes at least one input device identifier and at least one output device identifier associated with each audio route of the configured audio routing list information,
wherein the audio routing content type information includes at least one content type associated with each audio route of the configured audio routing list information, and
wherein the at least one content type includes a phone call, and a media playback.
10. A device for performing audio routing of an active audio in a wireless communication system, the device comprising:
a transceiver for performing signal transmission and reception with another device; and
a processor for controlling the transceiver and the device,
wherein the processor is configured to:
transmit, to the another device, audio routing basic information about the active audio through the transceiver;
receive, from the another device, an audio routing modification request through the transceiver; and
transmit, to the another device, modified audio routing-related information based on the audio routing modification request through the transceiver,
wherein the audio routing basic information includes available audio routing device information, configured audio routing list information, and audio routing content type information,
wherein the configured audio routing list information includes at least one input device identifier and at least one output device identifier associated with each audio route of the configured audio routing list information,
wherein the audio routing content type information includes at least one content type associated with each audio route of the configured audio routing list information, and
wherein the at least one content type includes a phone call, and a media playback.
