    [0002] The present invention relates, generally, to communication systems and, more particularly, the point-to-point group owner negotiation of wireless local area network (WLAN). Description of the State of the Art
    [0003] WLAN devices can discover each other and share data traffic, without the occurrence of a traditional access point, by forming a peer-to-peer network. To form a peer-to-peer network, one of the devices must be a group owner. To determine group ownership between two devices, the two devices participate in a group owner negotiation, during which the two devices exchange their intentions to act as a group owner. When the two devices indicate the same intent to be the group owner, a method is needed to fairly determine the group owner. Invention Summary

    [0019] The detailed description is set out below in connection with the accompanying drawings and is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a general understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some examples, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
    [0020] Various aspects of communication systems will now be presented with reference to various apparatus and methods. These apparatuses and methods will be described in the detailed description below and illustrated in the accompanying drawings, by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using electronic hardware, computer software, or any combination of these. Whether such elements are implemented as hardware or software will depend on the specific application and design constraints imposed on the entire system.
    [0021] By way of example, an element, or any part of an element, or any combination of elements, can be implemented with a "processing system" that includes one or more processors. Examples of processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGA), programmable logic devices (PLDs), state machines, switching logic, discrete hardware circuits, and other suitable hardware configured to perform the various features described throughout this invention. One or more processors in the processing system can run software. Software shall be broadly interpreted to mean instructions, instruction sets, codes, code segments, program codes, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables , execution chains, procedures, functions, etc., if referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. The software may reside on a computer-readable medium. The computer-readable medium may be a non-transient computer-readable medium. A non-transient computer-readable medium includes, by way of example, a magnetic storage device (eg hard disk, floppy disk, magnetic card), an optical disk (eg compact disk (CD), digital versatile disk (DVD) )), a smart card, a flash memory device (eg card, stick, key drive), random access memory (RAM), read memory (ROM), programmable ROM (PROM), erasable PROM (EPROM) , electrically erasable PROM (EEPROM), a register, a removable disk, and any other suitable medium for storing software and/or instructions that can be accessed and read by a computer. The computer-readable medium can also include, by way of example, a carrier wave, a transmission line, and any other medium suitable for transmitting software and/or instructions that can be accessed and read by a computer. The computer-readable medium may reside in the processing system, external to the processing system, or distributed across multiple entities, including the processing system. The computer-readable medium can be incorporated into a computer program product. By way of example, a computer program product may include a computer-readable medium on computer equipment. Those skilled in the art will recognize the best way to implement the described functionality presented throughout this invention which will depend on the specific application and general design constraints imposed on the overall system.
    [0022] Figure 1 is a conceptual diagram illustrating an example of a hardware implementation for an apparatus 100 employing a processing system 114. The processing system 114 can be implemented with a bus architecture, generally represented by the bus 102. bus 102 can include any number of interconnecting buses and bridges depending on the specific application of processing system 114 and general design constraints. Bus 102 connects together various circuits including one or more processors, represented generally by processor 104, and computer readable media, represented generally by computer readable medium 106. Bus 102 may also connect various other circuits, such as computer readable media sources. timing, peripherals, voltage regulators, and power management circuits, which are well known in the art, and therefore will not be described here. A bus interface 108 provides an interface between the bus 102 and a transceiver 110. The transceiver 110 provides a mechanism for communicating with various other devices over a transmission medium.
    [0023] Processor 104 is responsible for managing bus 102 and for general processing, including the execution of software stored on computer-readable medium 106. The software, when executed by processor 104, causes processing system 114 to perform the various functions described above for any specific device. Computer readable medium 106 can also be used to store data that is manipulated by processor 104 when running the software.
    [0024] Figure 2 is an example of a point-to-point communication system 200. The point-to-point communication system 200 includes a plurality of wireless devices 206, 208, 210, 212. The communication system peer-to-peer 200 can overlap with a cellular communication system, such as, for example, a wireless wide area network (WWAN). Some of the wireless devices 206, 208, 210, 212 can communicate together in point-to-point communication, some can communicate with base station 204, and some can do both. For example, as shown in Figure 2, wireless devices 206, 208 are in peer-to-peer communication and wireless devices 210, 212 are in peer-to-peer communication. Wireless device 212 is also communicating with base station 204.
    [0025] The wireless device may alternatively be referred to by those skilled in the art as user equipment, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, wireless node, remote unit, mobile device, device communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology. The base station may alternatively be referred to by those skilled in the art as an access point, a base station transceiver, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a Node B, an evolved Node B, or some other suitable terminology.
    [0026] The exemplary methods and apparatus discussed below are applicable to any of a variety of wireless peer-to-peer communication systems, such as, for example, a FlashLinQ-based wireless peer-to-peer communication system, WiMedia, Bluetooth, ZigBee, or Wi-Fi based on the IEEE 802.11 standard. To simplify the discussion, exemplary methods and apparatus are discussed within the context of FlashLinQ. However, one of skill in the art would understand that the exemplary methods and apparatus are more generally applicable to a variety of other wireless point-to-point communication systems.
    [0027] Figure 3 is a diagram 300 illustrating a peer-to-peer topology between a peer-to-peer group owner and peer-to-peer clients. A peer-to-peer group of peer-to-peer devices includes a peer-to-peer group owner and one or more clients connected to the group owner. As shown in Figure 3, wireless device 302 is the peer-to-peer group owner and wireless devices 304, 306, 308 are peer-to-peer clients connected to the peer-to-peer owner.
    [0028] Figure 4 is a diagram 400 illustrating an exchange of group owner negotiation messages. To determine peer-to-peer group ownership between two devices, the two devices participate in group ownership negotiation. As shown in Figure 4, wireless device 402 sends a group owner negotiation request 406 to wireless device 404. Group owner negotiation request 406 includes a point-to-point information element (IE) , which includes a Group Owner Intent attribute including a group owner intent value that indicates the intent of wireless device 402 to be group owner. Any range of values can be used to indicate intent. In one example, the values range from 0 to 15, with 0 indicating no desire to be the group owner and 15 indicating the need to be the group owner. Wireless device 404 responds to the request by sending a 408 group owner negotiation response. The 408 group owner negotiation response includes a peer-to-peer IE, which includes a Group Owner Intent attribute including a group owner intent value indicating the intent of wireless device 404 to be group owner. If group ownership is decided among wireless devices 402, 404, wireless device 402 responds to group owner negotiation response 408 with a group owner negotiation acknowledgment 410.
    [0029] Figure 5 is a diagram 500 illustrating the determination of group ownership. The value x1 is the group owner intent value of wireless device 402 and the value x2 is the group owner intent value of wireless devices 404. If x1 is not equal to x2 (block 502), then x1 is less than x2 (block 504), then wireless device 404 is the group owner (block 506). Otherwise, if x1 is not less than x2 (block 504), then wireless device 402 is the group owner (block 508). If x1 is equal to x2 (block 502) and both x1 and x2 are equal to 15 (or equal to a value indicating a need to be a group owner) (block 510), then the group owner negotiation fails , due to both wireless devices 402, 404wanting to be group owners (block 512). Otherwise, if both x1 and x2 are less than 15, then group ownership is determined based on the MAC addresses of wireless devices 402, 404 (blocks 514, 516). The reverse order of the six octets of MAC address of each wireless device 402, 404 is used to determine group ownership (block 514). The wireless device that has the highest value of six bytes becomes the group owner (block 516).
    [0030] As discussed above, group ownership requires more energy, and therefore group ownership may not be beneficial. As such, a device can be disproportionately overloaded by owning a group based on its MAC address. As such, a method is provided in Figure 6 to determine the group owner when the group owner intent is the same for two devices participating in the group owner negotiation.
    [0031] Figure 6 is a diagram 600 illustrating an exemplary method for determining group ownership. The value x1 is the group owner intent value of wireless device 402 and the value x2 is the group owner intent value of wireless devices 404. If x1 is not equal to x2 (block 602), and x1 is less than x2 (block 604), so wireless device 404 is the group owner (block 606). Otherwise, if x1 is not less than x2 (block 604), then wireless device 402 is the group owner (block 608). If x1 is equal to x2 (block 602), and both x1 and x2 are equal to 15 (or equal to a value indicating a need to be the group owner) (block 610), then the owner negotiation of group fails, due to both wireless devices, 402, 404 wanting to own the group (block 612). Otherwise, if both x1 and x2 are less than 15, then the group property is determined based on a tiebreaker value sent by wireless device 402, 404 (block 614).
    [0032] Referring again to Figure 4, in an exemplary configuration, the group owner negotiation request 406 includes a tiebreaker value. That is, the Group Owner Intent attribute can include a tiebreaker value. The tiebreaker value can be a bit, for example, with a 0 indicating that a tie between wireless devices 402, 404 with respect to the intent of group ownership is resolved by the receiving device becoming group owner, and a 1 indicating that the tie is resolved by the sending device becoming group owner. The tiebreaker value can be randomly adjusted by wireless device 402 in the first group owner negotiation request 406. The tiebreaker value sent in the group owner negotiation response 408 by wireless device 404 can be switched from the request 406 group owner trading list. For example, if the 406 group owner negotiation request includes a tiebreaker value of 0, then the 408 group owner negotiation response will include a tiebreaker value of 1, and therefore the wireless device 404 becomes you will become the group owner in the event of a tie. On the other hand, if the group owner negotiation request 406 includes a tiebreaker value of 1, then the group owner negotiation response 408 will include a tiebreaker value of 0, and therefore wireless device 402 will become the group owner in the event of a tie. The tiebreaker can be adjusted so that the values 0 and 1 have equal occurrences or nearly equal occurrences, on average.
    [0033] Figure 7A is a table 700 that shows an exemplary Group Owner Intent attribute format. As shown in Figure 7A, the Group Owner Intent attribute includes an attribute identifier (ID) field, a length field, and a group owner intent field. The Attribute ID field is shown as 4, but it can be any default value used to indicate that the attribute is for group owner intent. The length field is the length of the following fields in the attribute. The group owner intent field is a variable value as shown in Figure 7B.
    [0034] Figure 7B is a table 750 that shows an exemplary group owner intent field definition. The group owner intent field includes a group owner intent value to indicate a degree of intent to be the group owner. The group owner intent value can be a relative value between 0 and 15 used to indicate how willing the wireless device is to be the group owner. A 0 can indicate no desire, and 15 can indicate a need to own a group, with values between 0 and 15 indicating a degree of intention to own a group between the extremes. Although the intent value is indicated to be between 0 and 15, other values can be used to indicate group owner intent. The group owner intent field also includes a tiebreaker value, which, as discussed above, can be a bit, with 0 indicating that the device receiving the group owner negotiation message with the Owner Intent attribute of Group must be the group owner, and 1 indicating that the device sending the group owner negotiation request message with the Group Owner Intent attribute must be the group owner. The tiebreaker value is used when the intent values in the group owner request message and the group owner reply message are the same and less than 15.
    [0035] Figure 8 is a flowchart 800 of an exemplary method. The method is performed by a wireless device first. As shown in Figure 8, the first wireless device determines a tiebreak value and sends a first message including a first intent and the tiebreaker value to be a group owner to a second wireless device (block 802). The first wireless device receives a second message including a second intent to be the group owner from the second wireless device (block 804). The first wireless device determines which of the first wireless device or second wireless device should be the group owner based on the first intent, second intent, or tiebreaker value (block 806). The tiebreaker value can be a bit. In such a configuration, the first wireless device can make each tiebreaker value have equal occurrence, on average, and therefore subsequently send group owner negotiation request messages, and can adjust the value to 0 or 1 uniformly. on average (block808). In a configuration, the tiebreaker value selection can always be random with an equal probability of selecting 0 or 1. Other configurations are possible, as long as the value is uniformly adjusted to 0 or 1 on the mean.
    [0036] The value can be a tiebreaker value used to determine which of the first wireless device or the second wireless device should be the group owner when the first intent equals the second intent. The tiebreaker value can be used to determine which of the first wireless device or the second wireless device should be the group owner only when the first intent and second intent both indicate a lack of need to be the group owner. The first message can include the value, the second message can include a second value determined based on the value, and the first wireless device can determine which of the first wireless device or the second wireless device should be the group owner as well. based on the second value. The value and second value can be one bit each, the second value can be toggled from the value such that the second value is 1 when the value is 0 and the second value is 0 when the value is 1 , and the first wireless device can determine which of the first wireless device or the second wireless device should be the group owner based on which of the value or second value is 1. The first message can be a request for group owner negotiation and the second message can be a group owner negotiation response.
    [0037] Figure 9 is a flowchart 900 of an exemplary method. The method is performed by a first wireless device. The second message can include a second alternate value based on the value. In such a configuration, determining which of the first wireless device or the second wireless device should be the group owner (block 808) comprises determining that the first wireless device is the group owner when the first intent is greater than the second intent (block 902), determine that the second wireless device is the group owner when the second intent is greater than the first intent (block 904), determine that neither the first wireless device nor the second wireless device should be the group owner when first intent and second intent are the same and both indicate the need to be the group owner (block 906), determine that the first wireless device must be the group owner when the first intent and second intent are equal, and the value indicates that the first wireless device must be the group owner (block 908), and determines that the second wireless device must only is the group owner when the first intent and second intent are the same, and the second value indicates that the second wireless device must be the group owner (block 910).
    [0038] Figure 10 is a conceptual block diagram 1000 illustrating the functionality of an exemplary apparatus 100, which is a first wireless device. Apparatus 100 includes a module 1002 that sends a first message including a first intent to be a group owner and a value to a second wireless device. Apparatus 100 also includes a module 1004 that receives a second message including a second intent to be the group owner from the second wireless device. Apparatus 100 also includes a module 1006 that determines which of the first wireless device or the second wireless device should be the group owner based on first intent, second intent, and value.
    [0039] Referring to Figure 1, in one configuration, the apparatus 100 for wireless communication includes mechanisms for sending a first message including a first intention to be a group owner and a value for a second apparatus, mechanisms for receiving a second message including a second intent to be the group owner of the second appliance, and mechanisms to determine which of the appliance or second appliance should be the group owner based on the first intent, second intent, and value. In one configuration, apparatus 100 also includes mechanisms for adjusting the value of 0 or 1 uniformly to the mean. When the second message includes a second alternate value based on the value, mechanisms for determining which of the first wireless device or second wireless device should be the group owner may also include mechanisms for determining which of the first wireless device is the group owner when the first intent is greater than the second intent, mechanisms to determine that the second wireless device is the group owner when the second intent is greater than the first intent, mechanisms to determine that neither the first wireless device or the second wireless device must be the group owner when the first intent and the second intent are the same, and both indicate a need to be the group owner, mechanisms for determining that the first wireless device must be the group owner when the first intention and the second intention are the same and the value indicates that the first device without wire must be the group owner, and mechanisms to determine that the second wireless device must be the group owner when the first intent and second intent are the same and the second value indicates that the second wireless device must be the owner of group. The mechanisms mentioned above refer to the processing system 114, configured to perform the functions described by the mechanisms mentioned above.
