Abstract

A communicating method of a communication device for connecting to a first network and a second network includes: when a rescheduling condition is reached, rescheduling a wake up period of the communication device for the first network at least according to a wake up period of the communication device for the second network; wherein the wake up period of the communication device for the first network is rescheduled by making the communication device a master device in the first network through adjusting a preference parameter of the first network.

Claims

1. A communicating method of a communication device for connecting to a first network and a second network, comprising:

when a rescheduling condition is reached, rescheduling a wake up period of the communication device for the first network at least according to a wake up period of the communication device for the second network;

wherein the wake up period of the communication device for the first network is rescheduled by making the communication device a master device in the first network through adjusting a preference parameter of the first network.

2. The communicating method of claim 1, wherein the first network corresponds to a first channel and the second network corresponds to a second channel, and the rescheduling condition comprises:

the wake up period of the communication device for the first network overlaps the wakeup period of the communication device for the second network when the first channel is different from the second channel.

3. The communicating method of claim 2, wherein the wake up period of the communication device for the first network does not overlap the wakeup period of the communication device for the second network after rescheduling the wake up period of the communication device for the first network.

4. The communicating method of claim 1, wherein the first network corresponds to a first channel and the second network corresponds to a second channel, and the rescheduling condition comprises:

the wake up period of the communication device for the first network does not overlap the wakeup period of the communication device for the second network when the first channel is identical to the second channel.

5. The communicating method of claim 4, wherein the wake up period of the communication device for the first network overlaps the wakeup period of the communication device for the second network after rescheduling the wake up period of the communication device for the first network.

6. The communicating method of claim 1, wherein the communication device determines a start point of the wake up period for communication devices connecting in the first network after the communication device is made the master device.

7. The communicating method of claim 1, wherein rescheduling the wake up period of the communication device for the first network at least according to the wake up period of the communication for the second network when the rescheduling condition is reached comprises:

connecting to the first network; and

when connected to the first network;

detecting the wake up period of the communication device for the first network and the wake up period of the communication for the second network; and

rescheduling the wake up period of the communication device for the first network when the rescheduling condition is reached.

8. The communicating method of claim 1, further comprising:

sending beacons to other communication devices connecting in the first network during the wake up period of the communication device for the first network.

9. The communicating method of claim 1, further comprising:

listening for beacons from an access point of the second network during the wake up period of the communication device for the second network.

10. The communicating method of claim 1, wherein the first network is Wi-Fi aware.

11. An electronic device for connecting a first network and a second network, comprising:

a storage device, arranged to store a program code; and

a processor, arranged to execute the program code;

wherein when loaded and executed by the processor, the program code instructs the processor to execute following steps;

when a rescheduling condition is reached, rescheduling a wake up period of the communication device for the first network at least according to a wake up period of the communication device for the second network;

wherein the wake up period of the communication device for the first network is rescheduled by making the communication device a master device in the first network through adjusting a preference parameter of the first network.

12. The electronic device of claim 11, wherein the first network corresponds to a first channel and the second network corresponds to a second channel, and the rescheduling condition comprises:

the wake up period of the electronic device for the first network overlaps the wakeup period of the electronic device for the second network when the first channel is different from the second channel.

13. The electronic device of claim 12, wherein the wake up period of the electronic device for the first network does not overlap the wakeup period of the electronic device for the second network after rescheduling the wake up period of the communication device for the first network.

14. The electronic device of claim 11, wherein the first network corresponds to a first channel and the second network corresponds to a second channel, and the rescheduling condition comprises:

the wake up period of the electronic device for the first network does not overlap the wakeup period of the electronic device for the second network when the first channel is identical to the second channel.

15. The electronic device of claim 14, wherein the wake up period of the electronic device for the first network overlaps the wakeup period of the electronic device for the second network after rescheduling the wake up period of the communication device for the first network.

16. The electronic device of claim 11, wherein the electronic device determines a start point of the wake up period for electronic devices connecting in the first network after the communication device is made the master device.

17. The electronic device of claim 11, wherein rescheduling the wake up period of the electronic device for the first network at least according to the wake up period of the communication for the second network when the rescheduling condition is reached comprises:

connecting to the first network;

detecting the wake up period of the electronic device for the first network and the wake up period of the communication for the second network; and

rescheduling the wake up period of the electronic device for the first network when the rescheduling condition is reached.

18. The electronic device of claim 11, wherein the program code instructs the processor to further execute the following step:

sending beacons to other electronic devices connecting in the first network during the wake up period of the electronic device for the first network.

19. The electronic device of claim 11, wherein the program code instructs the processor to further execute the following step:

listening for beacons from an access point of the second network during the wake up period of the electronic device for the second network.

20. The electronic device of claim 11, wherein the first network is Wi-Fi aware.
