Method, device, and computer program for controlling and managing state of peripheral device in wireless communication system, and recording medium therefor
The present disclosure relates to a method, a device, and a computer program for controlling and managing a state of a peripheral device in a wireless communication system, and a recording medium therefor. According to an embodiment of the present disclosure, a method for changing an audio stream session-related state may include the steps of: acquiring information relating to a current audio stream session-related state of a second device before a first device in a first audio stream session-related state performs transition of an audio stream session-related state; determining a second audio stream session-related state of the first device at least on the basis of the current audio stream session-related state of the second device; and performing the transition of the audio stream session-related state by the first device on the basis of the second audio stream session-related state.
1. A method performed by a client device in a wireless communication system, the method comprising:
transmitting, to a server, a write message for initiating an operation related to audio data, based on a source endpoint being in a first state, wherein a current operation related to the audio data by the server for the source endpoint in the first state is maintained until the server transitions the source endpoint to a second state; and
receiving, from the server, a notification message for notifying at least one characteristic of the source endpoint being in the second state.
2. The method of claim 1 , wherein:
the client device initiates the operation based on the client device being ready to change consuming of the audio data transmitted for the source endpoint by the server.
3. The method of claim 1 , wherein:
states of the source endpoint including the first state and the second state include at least two states of a group of states including idle, codec configured, quality of service (QoS) configured, enabling, streaming, disabling, or releasing.
4. The method of claim 1 , wherein:
each of the server and the client device includes a Bluetooth Low Energy (BLE) protocol stack.
5. A client device in a wireless communication system, the device comprising:
a transceiver;
a memory; and
a processor,
wherein the processor is configured to:
transmit, through the transceiver, to a server, a write message for initiating an operation related to audio data, based on a source endpoint being in a first state, wherein a current operation related to the audio data by the server for the source endpoint in the first state is maintained until the server transitions the source endpoint to a second state; and
receive, through the transceiver, from the server, a notification message for notifying at least one characteristic of the source endpoint being in the second state.
6. The device of claim 5 , wherein:
the client device initiates the operation based on the client device being ready to change consuming of the audio data transmitted for the source endpoint by the server.
7. The device of claim 5 , wherein:
states of the source endpoint including the first state and the second state include at least two states of a group of states including idle, codec configured, quality of service (QoS) configured, enabling, streaming, disabling, or releasing.
8. The device of claim 5 , wherein:
each of the server and the client device includes a Bluetooth Low Energy (BLE) protocol stack.
