Abstract

Provided are an electronic device and method of determining a peer-to-peer (P2P) operating channel. The electronic device includes a communication interface; and a processor configured to acquire access point (AP) connection information of the electronic device about a wireless connection to an AP and BT connection information of the electronic device about a connection to a Bluetooth device, receive, from a peer device attempting to establish a P2P connection to the electronic device, AP connection information of the peer device about a wireless connection to an AP, determine a P2P operating channel between the electronic device and the peer device based on the AP connection information and the BT connection information of the electronic device and the AP connection information of the peer device, and establish a P2P connection between the electronic device and the peer device according to the determined P2P operating channel.

First claim

What is claimed is:

1. An electronic device comprising:
a communication interface comprising:
a first communication interface which communicates based on a first communication standard using a first frequency band, and
a second communication interface which communicates based on a second communication standard using at least one of the first frequency band and a second frequency band;

a memory storing one or more instructions; and
a processor configured to execute the one or more instructions stored in the memory to:
acquire connection information of the electronic device indicating whether the electronic device is currently connected with an external device through the first communication interface using the first communication standard,
obtain, from a peer device attempting to establish a peer-to-peer, P2P, connection according to the second communication standard to the electronic device, access point connection information of the peer device comprising information on a frequency band which is currently used in a wireless connection which the peer device communicates with an access point based on the second communication standard,
when the frequency band which is currently used in the wireless connection which the peer device communicates with the access point based on the second communication standard is the first frequency band, and the connection information of the electronic device indicates that the electronic device is connected with the external device through the first communication interface using the first communication standard, determine a P2P operating frequency band between the electronic device and the peer device as the second frequency band,
when the frequency band which is currently used in the wireless connection which the peer device communicates with the access point based on the second communication standard is the first frequency band, and the connection information of the electronic device indicates that the electronic device is not connected with the external device through the first communication interface using the first communication standard, determine the P2P operating frequency band between the electronic device and the peer device as the first frequency band, and

establish a P2P connection between the electronic device and the peer device according to the determined P2P operating frequency band.

2. The electronic device of claim 1 , wherein the first communication standard is Bluetooth, and the second communication standard is WiFi.

3. The electronic device of claim 1 , wherein the first frequency band is 2.4 GHz, and the second frequency band is 5 GHz.

4. The electronic device of claim 1 , wherein the processor is further configured to execute the one or more instructions to acquire the access point connection information of the peer device from a message received from the peer device for a P2P search or a connection request.

5. The electronic device of claim 4 , wherein the message received from the peer device comprises at least one of a group owner, GO, negotiation request message or an invitation request message.

6. The electronic device of claim 5 , wherein the access point connection information of the peer device is acquired through a vender specific information element of the GO negotiation request message or the invitation request message.

7. The electronic device of claim 1 , wherein the processor is further configured to execute the one or more instructions to determine the P2P operating channel further based on information about whether the electronic device supports dual simultaneous band (DSB) and information about whether the peer device supports real simultaneous dual band (RSDB).

8. An operating method of an electronic device comprising a first communication interface which communicates based on a first communication standard using a first frequency band, and a second communication interface which communicates based on a second communication standard using at least one of the first frequency band and a second frequency band, the operating method comprising:
acquiring connection information of the electronic device indicating whether the electronic device is currently connected with an external device through the first communication interface using the first communication standard,
obtaining, from a peer device attempting to establish a peer-to-peer, P2P, connection according to the second communication standard to the electronic device, access point connection information of the peer device comprising information on a frequency band which is currently used in a wireless connection which the peer device communicates with an access point based on the second communication standard,
when the frequency band is currently used in the wireless connection which the peer device communicates with the access point based on the second communication standard is the first frequency band, and the connection information of the electronic device indicates that the electronic device is connected with the external device through the first communication interface using the first communication standard, determining a P2P operating frequency band between the electronic device and the peer device as the second frequency band,
when the frequency band which is currently used in the wireless connection which the peer device communicates with the access point based on the second communication standard is the first frequency band, and the connection information of the electronic device indicates that the electronic device is not connected with the external device through the first communication interface using the first communication standard, determining the P2P operating frequency band between the electronic device and the peer device as the first frequency band, and

establishing a P2P connection between the electronic device and the peer device according to the determined P2P operating frequency band.

9. The operating method of claim 8 , wherein the first communication standard is Bluetooth, and the second communication standard is WiFi.

10. The operating method of claim 8 , wherein the first frequency band is 2.4 GHZ, and the second frequency band is 5 GHZ.

11. The operating method of claim 8 , further comprising acquiring the access point connection information of the peer device from a message received from the peer device for a P2P search or a connection request.

12. The operating method of claim 11 , wherein the message received from the peer device comprises at least one of a group owner, GO, negotiation request message or an invitation request message.

13. The operating method of claim 12 , wherein the access point connection information of the peer device is acquired through a vender specific information element of the GO negotiation request message or the invitation request message.

14. A computer program product comprising a non-transitory computer-readable recording medium storing a program for performing an operating method of an electronic device comprising a first communication interface which communicates based on a first communication standard using a first frequency band, and a second communication interface which communicates based on a second communication standard using at least one of the first frequency band and a second frequency band, the operating method comprising:
acquiring connection information of the electronic device indicating whether the electronic device is currently connected with an external device through the first communication interface using the first communication standard,
obtaining, from a peer device attempting to establish a peer-to-peer, P2P, connection accor
