Method and apparatus for negotiating device roles in a wireless network
First Claim
1. A method for negotiating a master-client relationship in a peer-to-peer (P2P) wireless communication network, the method comprising:
- transmitting, with a first device, a first packet to a second device, wherein the first packet includes a first value indicative of a priority for the first device to become a master in the P2P wireless communication network, whereinthe first value is chosen from a range of priority values defined by a communication protocol for indicating to other devices a relative preference for becoming a master in P2P wireless communication networks,the range of priority values includes a first priority value at a first end of the range and a second priority value at a second end of the range,the first priority value corresponds to always being the master,the second priority value corresponds to never being the master,the range of values includes a plurality of priority values between the first priority value and the second priority value that correspond to respective relative preferences for becoming the master between i) always being the master and ii) never being the master, andthe first value having been selected, from the range of priority values, prior to the first device ever having transmitted to, or received from, the second device;
receiving, at the first device, a second packet transmitted by the second device, wherein the second packet includes a second value indicative of a priority for the second device to become the master in the P2P wireless communication network, wherein the second value is chosen from the range of priority values defined by the communication protocol;
comparing, at the first device, the first value with the second value; and
determining, at the first device, whether the first device is to become the master or a client in the P2P wireless communication network based on the comparison of the first value with the second value, including;
if the first value is different from the second value;
selecting the first device to become the master in response to the first value indicating a higher priority to be the master than the second value, andselecting the first device to become the client in response to the second value indicating a higher priority to be the master than the first value.

Abstract
A first device transmits a first packet to a second device, the first packet including a first value indicative of a priority for the first device to become a master in a peer-to-peer (P2P) wireless communication network. The first device receives a second packet transmitted by the second device, wherein the second packet includes a second value indicative of a priority for the second device to become the master in the P2P wireless communication network. The first device compares the first value with the second value, and determines whether the first device is to become the master or a client in the P2P wireless communication network based on the comparison of the first value with the second value.

10. A first communication device for use in a peer-to-peer (P2P) wireless communication network, the first communication device comprising:
-
a transceiver; and a controller coupled to the transceiver, the controller configured to; transmit, using the transceiver, a first packet to a second communication device, wherein the first packet includes a first value indicative of a priority for the first communication device to become a master in the P2P wireless communication network, wherein the first value is chosen from a range of priority values defined by a communication protocol for indicating to other devices a relative preference for becoming a master in P2P wireless communication networks, the range of priority values includes a first priority value at a first end of the range and a second priority value at a second end of the range, the first priority value corresponds to always being the master, the second priority value corresponds to never being the master, the range of values includes a plurality of priority values between the first priority value and the second priority value that correspond to respective relative preferences for becoming the master between i) always being the master and ii) never being the master, and the first value having been selected, from the range of priority values, prior to the first device ever having transmitted to, or received from, the second device; wherein the controller is further configured to; receive, via the transceiver, a second packet transmitted by the second communication device, wherein the second packet includes a second value indicative of a priority for the second communication device to become the master in the P2P wireless communication network, wherein the second value is chosen from the range of priority values defined by the communication protocol, compare the first value with the second value, and determine whether the first communication device is to become the master or a client in the P2P wireless communication network based on the comparison of the first value with the second value, including; if the first value is different from the second value; selecting the first communication device to become the master in response to the first value indicating a higher priority to be the master than the second value, and selecting the first device to become the client in response to the second value indicating a higher priority to be the master than the first value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A tangible, non-transitory computer readable medium storing machine readable instructions that, when executed by a processor of a first communication device, cause the processor to:
-
cause the first communication device to transmit a first packet to a second communication device, wherein the first packet includes a first value indicative of a priority for the first communication device to become a master in the peer-to-peer (P2P) wireless communication network, wherein the first value is chosen from a range of priority values defined by a communication protocol for indicating to other communication devices a relative preference for becoming a master in P2P wireless communication networks, the range of priority values includes a first priority value at a first end of the range and a second priority value at a second end of the range, the first priority value corresponds to always being the master, the second priority value corresponds to never being the master, the range of values includes a plurality of priority values between the first priority value and the second priority value that correspond to respective relative preferences for becoming the master between i) always being the master and ii) never being the master, and the first value having been selected, from the range of priority values, prior to the first device ever having transmitted to, or received from, the second device; compare the first value with a second value, the second value included in a second packet received by the first communication device, the second value indicative of a priority for the second communication device to become the master in the P2P wireless communication network, wherein the second value is chosen from the range of priority values defined by the communication protocol; and determine whether the first communication device is to become the master or a client in the P2P wireless communication network based on the comparison of the first value with the second value, including; if the first value is different from the second value; selecting the first device to become the master in response to the first value indicating a higher priority to be the master than the second value, and selecting the first device to become the client in response to the second value indicating a higher priority to be the master than the first value. - View Dependent Claims (20, 21)
