Abstract

A method and apparatus for communicating streaming data in a Bluetooth-based wireless communication system is provided. An electronic device according to the present disclosure includes a communication interface configured to perform wireless Bluetooth communication with an external electronic device and a controller configured to control the communication interface, in which the controller is further configured to detect a communication state using a first packet data configuration and communicate with the external electronic device by using a second packet data configuration that is different from the first packet data configuration, based on the communication state.

First claim

What is claimed is:

1. An electronic device comprising:
a communication interface configured to perform a short-range wireless communication with an external electronic device; and
at least one processor electrically connected with the communication interface and configured to:
identify a type of a communication state based on a state of a buffer in which packet data temporarily waits in the electronic device and a retransmission rate of packet data transmitted using a first packet data configuration,
identify a second packet data configuration corresponding to the identified type of the communication state, wherein the second packet data configuration is one of a plurality of packet data configurations different from the first packet data configuration, and
control the communication interface to communicate with the external electronic device using the second packet data configuration based on the communication state,
wherein the at least one processor is, when identifying the type of the communication state, further configured to:
identify a first type indicating a good state of an air interface environment as the type of the communication state based on channel information received from the external electronic device;
identify a second type of the air interface environment as the type of the communication state based on the retransmission rate being less than a first threshold;
identify a third type of the air interface environment as the type of the communication state based on the retransmission rate being equal to or greater than the first threshold and less than a second threshold that is greater than the first threshold; and
identify a fourth type of the air interface environment as the type of the communication state based on at least one of the retransmission rate being equal to or greater than the second threshold.

2. The electronic device of claim 1 , wherein the first packet data configuration and the second packet data configuration comprise at least one of a packet transmission rate, a number of frames per packet, or a compressed frame size.

3. The electronic device of claim 1 , wherein the at least one processor is further configured to, during a transmission of packet data using the first packet data configuration, detect the communication state based on whether a request for stopping the transmission of the packet data is received from the external electronic device.

4. The electronic device of claim 1 , wherein the at least one processor is further configured to, during a transmission of packet data using the first packet data configuration, detect the communication state based on the state of the buffer in which packet data temporarily waits in the electronic device and on whether a request for stopping the transmission of the packet data is received from the external electronic device.

5. The electronic device of claim 1 , wherein the at least one processor is further configured to detect the communication state based on channel information associated with a channel in which packet data is transmitted using the first packet data configuration.

6. The electronic device of claim 1 , wherein the at least one processor is further configured to:
determine a packet transmission rate of transmittable packet data based on the communication state; and
determine the second packet data configuration based on the determined packet transmission rate.

7. The electronic device of claim 1 , wherein the at least one processor is further configured to determine the second packet data configuration based on whether the communication state continues for a predetermined time.

8. The electronic device of claim 1 , further comprising a communication state detector configured to detect a communication state of communication of packet data performed by the communication interface,
wherein the at least one processor is further configured to:
receive communication state information detected by the communication interface during a transmission of packet data using the first packet data configuration; and
detect the communication state based on the received communication state information.

identifying a type of a communication state based on a state of a buffer in which packet data temporarily waits in the electronic device and a retransmission rate of packet data transmitted using a first packet data configuration;
identifying a second packet data configuration corresponding to the identified type of the communication state, wherein the second packet data configuration is one of a plurality of packet data configurations different from the first packet data configuration, and
controlling a communication interface to communicating with an external electronic device using the second packet data configuration based on the communication state,
wherein identifying the type of the communication state comprises:
identifying a first type indicating a good state of an air interface environment, as the type of the communication state based on channel information received from the external electronic device;
identifying a second type of the air interface environment as the type of the communication state based on the retransmission rate being less than a first threshold;
identifying a third type of the air interface environment as the type of the communication state based on the retransmission rate being equal to or greater than the first threshold and less than a second threshold that is greater than the first threshold; and
identifying a fourth type of the air interface environment as the type of the communication state based on at least one of the retransmission rate being equal to or greater than the second threshold.

10. The method of claim 9 , wherein the first packet data configuration and the second packet data configuration comprise at least one of a packet transmission rate, a number of frames per packet, or a compressed frame size.

11. The method of claim 9 , further comprising:
during a transmission of the packet data using the first packet data configuration, detecting the communication state based on whether a request for stopping the transmission of the packet data is received from the external electronic device.

12. The method of claim 9 , further comprising:
during a transmission of packet data using the first packet data configuration, detecting the communication state based on the state of the buffer in which packet data temporarily waits in the electronic device and on whether a request for stopping transmission of the packet data is received from the external electronic device.

13. The method of claim 9 , further comprising:
detecting the communication state based on channel information associated with a channel in which packet data is transmitted using the first packet data configuration.

determining the second packet data configuration based on whether the communication state continues for a predetermined time.

16. The method of claim 9 , further comprising:
receiving communication state information during a transmission of the packet data using the first packet data configuration; and
detecting the communication state based on t
