Abstract

The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An electronic device for and a method of performing wireless communication are provided. The electronic device includes a first module configured to transmit signals to another electronic device via a first type of link; a second module configured to transmit signals to the another electronic device via a second type of link; and a controller configured to establish the first type of link and release from the second type of link if a predetermined event occurs.

Claims

1. An electronic device for performing wireless communication, the electronic device comprising:

a controller configured to;

communicate with another electronic device via a first direct link between the electronic device and the another electronic device,

determine that an amount of packet data to be transmitted via the first direct link is more than a threshold amount in a transmission queue, and

a time difference between a first time a packet is entered in the transmission queue and a second time the packet is processed from the transmission queue; and

if the amount of the packet data more than the threshold amount is maintained in the transmission queue longer than a first threshold time, and

the time difference is larger than a second threshold time, communicate with the another electronic device via a second direct link between the electronic device and

the another electronic device to transmit the packet data through the second direct link,

wherein the second direct link is established before the first direct link is released,

wherein the second direct link requires less power than the first direct link, and

wherein the second direct link is established if a remaining amount of a battery of the electronic device is below a preset value.

2. The electronic device of claim 1, wherein the second direct link is established if a moving pattern is identified and the moving pattern indicates that the electronic device moves away from the another electronic device.

3. The electronic device of claim 1, wherein the second direct link is established if a currently executed service is identified and it is determined that the service is subject to management.

4. The electronic device of claim 1, wherein the second direct link is established if current traffic exceeds a predetermined value.

5. The electronic device of claim 1, wherein the second direct link is established if a distance to the electronic device exceeds a predetermined value.

6. The electronic device of claim 1, wherein the second direct link is established if link loss is identified.

7. The electronic device of claim 1, wherein the second link is established if a channel map and a channel classification are identified and the channel is congested.

8. The electronic device of claim 1, wherein the second direct link is established if link quality is less than a predetermined value.

9. The electronic device of claim 1, wherein the second direct link is established if a received signal strength indicator (RSSI) for the first direct link is below a preset value.

10. The electronic device of claim 1, wherein the second direct link is established by a host controller interface (HCI) command.

11. The electronic device of claim 1, wherein the second direct link is established if an interference level for the first direct link affected by at least one interference signal exceeds a predetermine level.

12. A method of performing wireless communication in an electronic device, the method comprising:

communicating with another electronic device via a first direct link between the electronic device and the another electronic device;

determining that an amount of packet data to be transmitted via the first direct link is more than a threshold amount in a transmission queue, and

a time difference between a first time a packet is entered in the transmission queue and a second time the packet is processed from the transmission queue; and

if the amount of the packet data more than the threshold amount is maintained in the transmission queue longer than a first threshold time, and

the time difference is larger than a second threshold time, communicating with the another electronic device via a second direct link between the electronic device and

the another electronic device to transmit the packet data through the second direct link,

wherein the second direct link is established before the first direct link is released, wherein the second direct link requires less power than the first direct link, and

wherein the second direct link is established if a remaining amount of a battery of the electronic device is below a preset value.

13. The method of claim 12, wherein the second direct link is established if a moving pattern is identified and the moving pattern indicates that the electronic device moves away from the another electronic device.

14. The method of claim 12, wherein the second direct link is established if a currently executed service is identified and it is determined that the service is subject to management.

15. The method of claim 12, wherein the second direct link is established if current traffic exceeds a predetermined value.

16. The method of claim 12, wherein the second direct link is established if a distance to the another electronic device exceeds a predetermined value.

17. The method of claim 12, wherein the second direct link is established if link loss is identified.

18. The method of claim 12, wherein the second direct link is established if a channel map and a channel classification are identified and the channel is congested.

19. The method of claim 12, wherein the second direct link is established if link quality is less than a predetermined value.

20. The method of claim 12, wherein the second direct link is established if a received signal strength indicator (RSSI) for the first direct link is below a preset value.

21. The method of claim 12, wherein the second direct link is established by a host controller interface (HCI) command.

22. The method of claim 12, wherein the second direct link is established if an interference level for the first direct link affected by at least one interference signal exceeds a predetermine level.
