Abstract

An electronic device is provided for use in a NAN cluster. The electronic device includes Wi-Fi communication circuitry; a memory that stores instructions; and a processor that executes the instructions to, while the electronic device operates as a master of the NAN cluster based on a first master preference, control the Wi-Fi communication circuitry to transmit discovery signals outside of discovery windows (DWs), based on a determination that a state of the processor is switched from a wake-up state to a sleep state, change control information for the NAN cluster, wherein the changed control information for the NAN cluster includes data regarding a second master preference that is distinct from the first master preference, and provide the changed control information to the Wi-Fi communication circuitry. The Wi-Fi communication circuitry, while the processor is switched to the sleep state, transmits the changed control information for the NAN cluster.

First claim

What is claimed is:

1. An electronic device in a neighbor awareness networking (NAN) cluster, the electronic device comprising:
wireless fidelity (Wi-Fi) communication circuitry;
a memory configured to store instructions; and
a processor configured to execute the instructions, which instruct the processor to:
while the electronic device operates as a master of the NAN cluster based on a first master preference, control the Wi-Fi communication circuitry to transmit discovery signals outside of discovery windows (DWs),
based on a determination that a state of the processor is switched from a wake-up state to a sleep state, change control information for the NAN cluster, wherein the changed control information for the NAN cluster includes data regarding a second master preference that is distinct from the first master preference, and
provide the changed control information to the Wi-Fi communication circuitry, and

wherein the Wi-Fi communication circuitry is configured to, while the processor is in the sleep state switched from the wake-up state, transmit the changed control information that includes the data regarding the second master preference.

2. The electronic device of claim 1 , further comprising a display,
wherein the display is in a turn-off state or a low power state while the processor is in the sleep state.

3. The electronic device of claim 1 , wherein the electronic device operates as a non-master of the NAN cluster if at least one device that has a master preference higher than the second master preference exists in the NAN cluster.

4. The electronic device of claim 1 , wherein the instructions further instruct the processor to:
receive, in at least one of the DWs, a synchronization signal including data regarding a master preference of another electronic device that operates as a non-master in the NAN cluster, and
identify the second master preference based on the data regarding the master preference of the other electronic device in the NAN cluster.

5. The electronic device of claim 1 , wherein the Wi-Fi communication circuitry is further configured to, while the processor is in the sleep state, transmit, in at least one of the DWs, a synchronization signal including the changed control information that includes the data regarding the second master preference.

6. The electronic device of claim 1 , wherein each of the first and second master preferences is usable for determining a master in the NAN cluster, and
wherein each of the discovery signals is usable for notifying a presence of the NAN cluster.

7. The electronic device of claim 1 , wherein the instructions further instruct the processor to:
based on the determination that the state of the processor is switched from the wake-up state to the sleep state, determine to defer transmissions of the discovery signals outside of the DWs instead of changing the control information for the NAN cluster, and
after determining to defer the transmissions of the discovery signals outside of the DWs, switch the state of the processor from the wake-up state to the sleep state, and
wherein the Wi-Fi communication circuitry is further configured to defer the transmissions of the discovery signals outside of the DWs while the processor is in the sleep state.

8. An electronic device in a neighbor awareness networking (NAN) cluster, the electronic device comprising:
a battery;
wireless fidelity (Wi-Fi) communication circuitry;
a memory configured to store instructions; and
a processor configured to execute the instructions, which instruct the processor to:
while the electronic device operates as a master of the NAN cluster based on a first master preference, control the Wi-Fi communication circuitry to transmit discovery signals outside of discovery windows (DWs),
based on a state related to the battery, change control information for the NAN cluster, wherein the changed control information for the NAN cluster includes data regarding a second master preference that is distinct from the first master preference, and
provide the changed control information to the Wi-Fi communication circuitry,

wherein the Wi-Fi communication circuitry is configured to transmit the changed control information that includes the data regarding the second master preference.

9. The electronic device of claim 8 , wherein the instructions further instruct the processor to determine the state related to the battery based at least in part on a remaining power of the battery.

10. The electronic device of claim 8 , wherein the electronic device operates as a non-master of the NAN cluster if at least one device that has a master preference higher than the second master preference exists in the NAN cluster.

receive, in at least one of the DWs, a synchronization signal including data regarding a master preference of another electronic device that operates as a non-master in the NAN cluster, and
identify the second master preference based on the data regarding the master preference of the other electronic device in the NAN cluster.

12. The electronic device of claim 8 , wherein the Wi-Fi communication circuitry is further configured to transmit, in at least one of the DWs, a synchronization signal including the changed control information that includes the data regarding the second master preference.

13. An electronic device in a neighbor awareness networking (NAN) cluster, the electronic device comprising:
a battery;
wireless fidelity (Wi-Fi) communication circuitry;
a memory configured to store instructions; and
a processor configured to execute the instructions, which instruct the processor to:
while the electronic device operates as a master of the NAN cluster based on a first master preference, control the Wi-Fi communication circuitry to transmit discovery signals outside of discovery windows (DWs),
based on a state related to the electronic device, change control information for the NAN cluster, wherein the changed control information for the NAN cluster includes data regarding a second master preference that is distinct from the first master preference, and
provide the changed control information to the Wi-Fi communication circuitry,

wherein the Wi-Fi communication circuitry is configured to transmit the changed control information that includes the data regarding the second master preference.
