Abstract

An electronic device includes: a communication module; a memory; and at least one processor operatively connected to the communication module and the memory, wherein the at least one processor is configured to: control the communication module to generate a direct communication group in which an external electronic device operates as a group owner and the electronic device operates as a group client through a Wi-Fi direct connection with the external electronic device, to perform wireless communication; control the communication module to transmit, to the external electronic device, a schedule change request message requesting to change an operation schedule of the direct communication group, based on a change in an operating state, related to wireless communication through the direct communication group, of at least one of the at least one processor and the communication module; receive, through the communication module from the external electronic device, a response message including operation schedule information configured based on the schedule change request message; and control the communication module to perform wireless communication according to the operation schedule information of the response message received from the external electronic device.

First claim

What is claimed is:

1. An electronic device comprising:
communication circuitry;
at least one processor including processing circuitry; and
memory configured to store instructions which, when executed by the at least one processor individually or collectively, cause the electronic device to:
generate a direct communication group in which an external electronic device operates as a group owner and the electronic device operates as a group client through a Wi-Fi direct connection with the external electronic device, to perform wireless communication;
transmit, through the communication circuitry to the external electronic device operating as the group owner, a schedule change request message requesting to change an operation schedule of the direct communication group, based on at least one of the at least one processor or the communication circuitry entering an inactive state from an active state, or entering the active state from the inactive state, according to a change in an operating state of an application executed by the electronic device which provides a service through the direct communication group;
receive, through the communication circuitry from the external electronic device operating as the group owner, a response message comprising operation schedule information configured based on the schedule change request message; and
perform the wireless communication according to the operation schedule information of the response message received from the external electronic device operating as the group owner.

2. The electronic device of claim 1 , wherein the schedule change request message comprises at least one of information describing a current operating state, information describing a change time, or information describing a change interval.

3. The electronic device of claim 1 ,
wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to control the communication circuitry to transmit the schedule change request message in a peer-to-peer (P2P) presence request frame, and
wherein the P2P presence request frame comprises at least one of an attribute field, a duration field, or an interval field.

4. The electronic device of claim 3 ,
wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to receive, through the communication circuitry, the response message in a P2P presence response frame, and
wherein the P2P presence response frame comprises a status code indicating a result of the schedule change request message.

5. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to receive, through the communication circuitry, the response message transmitted in a predefined beacon frame.

6. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
control the communication circuitry to connect to the external electronic device operating as the group owner through a second communication channel different from a first communication channel for the wireless communication through the direct communication group; and
control the communication circuitry to transmit the schedule change request message through the second communication channel.

7. The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to, based on identifying that the wireless communication is performed by being connected to an access point through periodic channel change based on time division, generate the schedule change request message by including information on the periodic channel change.

8. A method of an electronic device, the method comprising:
generating a direct communication group in which an external electronic device operates as a group owner and the electronic device operates as a group client through a Wi-Fi direct connection with the external electronic device, to perform wireless communication;
transmitting, to the external electronic device operating as the group owner, a schedule change request message requesting to change an operation schedule of the direct communication group, based on at least one component of the electronic device entering an inactive state from an active state, or entering the active state from the inactive state, according to a change in an operating state of an application executed by the electronic device which provides a service through the direct communication group;
receiving, from the external electronic device operating as the group owner, a response message including operation schedule information configured based on the schedule change request message; and
performing the wireless communication with the external electronic device operating as the group owner according to the operation schedule information of the response message received from the external electronic device.

9. The method of claim 8 , wherein the schedule change request message comprises at least one of information describing a current operating state, information describing a change time, or information describing a change interval.

10. The method of claim 8 ,
wherein the schedule change request message is transmitted in a peer-to-peer (P2P) presence request frame, and
wherein the P2P presence request frame comprises at least one of an attribute field, a duration field, or an interval field.

11. The method of claim 10 ,
wherein the response message is received in a P2P presence response frame, and
wherein the P2P presence response frame comprises a status code indicating a result of the schedule change request message.

12. The method of claim 8 , wherein the response message is received in a predefined beacon frame.

13. The method of claim 8 , further comprising:
connecting to the external electronic device operating as the group owner through a second communication channel different from a first communication channel for the wireless communication through the direct communication group,
wherein the transmitting the schedule change request message comprises transmitting the schedule change request message through the second communication channel.

14. The method of claim 8 , further comprising:
identifying that the wireless communication is performed by being connected to an access point through periodic channel change based on time division; and
generating the schedule change request message by including information on the periodic channel change.

15. An electronic device comprising:
communication circuitry;
at least one processor including processing circuitry; and
memory configured to store instructions which, when executed by the at least one processor individually or collectively, cause the electronic device to:
operate as a group owner of a Wi-Fi direct communication group;
receive, through the communication circuitry from an external electronic device operating as a group client of the Wi-Fi direct communication group and connected through a Wi-Fi direct connection, a schedule change request message requesting to change an operation schedule of the Wi-Fi direct communication group, the schedule change request message being transmitted based on at least one component of the external electronic device operating as the group client entering an inactive state from an active state, or entering the active st
