Wi-Fi peer to peer communication protocol
In some embodiments, Wi-Fi equipment (for example, client site 106) can be led to each other with Peer Letter, for example, communication needs not move through intermediate access point.It is current in Wi-Fi Alliance that there are two types of Wi-Fi Peer-To-Peer agreements.One In the peer protocol of seed type, when two Wi-Fi equipments (for example, wireless site) communicate with one another, one of Wi-Fi equipment is practical On serve as pseudo- access point, and another serves as client device.Second of type of networking (NAN) is realized in referred to as neighbours In Wi-Fi peer protocol, two Wi-Fi client devices (wireless site) serve as the similar peer device to communicate with one another, for example, No one serves as access point.
In NAN system, adjacent wireless site is synchronous with what is communicated to ensure it for each implementable method of wireless site. In addition, the negotiable public discovery window of wireless site, for exchanging synchronous grouping, to assist in ensuring that the equipment being in direct communication with each other It obtains suitably synchronous can communicate.Once two wireless sites discovery window having the same, they can exchange synchronization Grouping to keep synchronous each other.Wireless site also can be used discovery window Exchange Service discovery frame to convey other information, for example, It was found that other availabilities except window.
NAN agreement includes two aspects: 1) synchronous and discovery (NAN 1.0) and 2) data path transmission (NAN 2.0).NAN 1.0 describes the method for NAN protocol synchronization and discovery.Two wireless sites (according to NAN 1.0) each other After it was found that, their implementable processes allow them to normal communication to establish NAN data path between them.Hereafter, Two wireless sites prepare common data path negotiation window, allow them to negotiation ability, synchronous requirement and exchange other Information on services.It is the time window that two wireless sites are communicated with one another that data path, which negotiates window, enables them Enough negotiate these abilities to require with synchronous, and exchanges this other information on services.Once having been set up data path negotiates window Mouth has simultaneously carried out the foundation of NAN data path, and wireless site can be carried out data path and synchronize, to assist in ensuring that two stations are kept It is synchronized with each other with normal communication.Finally, data path resource allocation is related to two reciprocity wireless sites, ditch is common to communication each other Common time slot and channel.In other words, which links up each other should use about them and at which for which channel Time slot is normally communicated between them with assisting in ensuring that.In addition, two equipment are linked up each other about which respectively will preferentially be used Channel and time slot are for the communication in future between them.
The embodiments described herein is also defined for for wireless site (including but not limited to NAN equipment) (at least portion Point) method (and/or mechanism) of adjacent wireless site is synchronized to based on mutual (or public) service between wireless site.
Based on the peer synchronization mutually serviced
In some specific implementations, reciprocity wireless site can on social channel periodicity sending (or broadcast) it is synchronous and/ Or discovery beacon, the social activity channel are, for example, the letter in peer protocol to send and/or reception is synchronous and/or discovery beacon is specified Road, reciprocity wireless site can periodically be tuned to the channel to receive and/or send (broadcast) such beacon, and carry out other Process, such as service negotiation and cluster management.It can be used for selecting to be anchored for example, synchronous and/or discovery beacon can carry (or including) (or timing) main equipment is (for example, other wireless sites can carry or via receiving beacon from anchoring main equipment or receiving including permitting The wireless site being permitted to be synchronized to the beacon of the information of anchoring main equipment and being synchronized to) information and/or form synchronization tree (or cluster), For example, as shown in Figure 4.For example, there is top ranked wireless site compared with adjacent wireless site in some specific implementations (for example, wireless site 401n) can be selected as being anchored main equipment (or timing master).The ranking can be based at least partially on The quantity of the current peer to peer connection (such as NAN data path or the data session of NAN data link) of wireless site, current equity The requirement of connection, such as service quality and/or scheduling limitation.In other words, the nothing with maximum restricted communication scheduling may be selected Line website is as anchoring main equipment.It may be noted that with the quantity increase of peer to peer connection and/or as quality of service requirement improves, Communication scheduling can become restricted bigger.Once by selecting, anchoring main equipment can via from anchoring main equipment (for example, for Wireless site 410a-410c) direct broadcast (and receive) beacon and/or via representing pull-off pole equipment to not setting from anchoring master The standby wireless site received within the scope of beacon is (for example, wireless site 410c can will be from the received synchronization of wireless site 401n Information is forwarded to wireless site 401d and 401e) forwarding synchronizing information, when being provided for the wireless site within synchronization tree (or cluster) Between it is synchronous.Note that synchronous and/or discovery beacon can also be used for service discovery.
Other than in addition to selection anchoring main equipment and/or forming synchronization tree (or cluster), also implementable synchronization and/or discovery beacon To merge for synchronization tree (or cluster).For example, as shown in figures 5a-5c, two clusters 505x and 505y can be very close to each other, such as scheme Shown in 5A.As shown, equipment 501a can be the anchoring main equipment for cluster 505x, and equipment 501b can be synchronous with 501e To equipment 501a.Similarly, equipment 501c can be the anchoring main equipment for cluster 505y, and equipment 501d can be synchronous with 501f To equipment 501c.Proceed to Fig. 5 B, enters within mutual communication range in equipment 501b and equipment 501c (for example, connecing very much When closely), the merging of cluster 505x and 505y can be initiated.During merging, it will select new anchoring is main to set based on such as ranking It is standby.In the example shown in the series of figures, equipment 501a has higher ranking compared with equipment 501c, to work as equipment 501b and 501c (example Such as, via discovery and/or sync beacon) exchange cluster information when, equipment (for example, 501a-501f) will select equipment 501a as It is anchored main equipment (for example, equipment 501a based on having higher ranking than equipment C), and cluster 505y is incorporated into cluster 505x In, as shown in Figure 5 C.Then, equipment 501b-501f is by Timing Synchronization to equipment 501a.Note that can within each cluster The service that equipment is supported independently carries out the merging of cluster.In other words, cluster merging can be embodied as equipment and is synchronized to top ranked set Standby function, and it is unrelated that mutual or public service whether can be provided with the equipment in each cluster.
But, in some specific implementations and/or situation, the timing tune of (or since it is caused) associated with cluster merging Section --- for example, as described above, it may be necessary to which equipment 501c and equipment 501d adjusts timing, so as to normal synchronized to equipment 501a --- it of short duration can influence the service quality of (for example, reduction) current peer-data session.In addition, if data session includes Delay-sensitive application, for example, display/screen mirror image, video and/or audio call etc., the potential decline of service quality can not User experience is influenced sharply.For example, if equipment 501a and 501b are carrying out file biography during cluster 505x and 505y merge Defeated application, and equipment 501c and 501d are carrying out low latency screen mirror image application, the merging of cluster can lead in mirror image application Visible degradation (for example, screen glitch, such as pixel is lost, frame solidifies and/or dither frame), to negatively affect user's body It tests.On the contrary, very little or none shadow may be influenced to the user experience of the file transfer applications between equipment 501a and 501b by merging It rings, for example, because the timing of equipment 501a and 501b can be unaffected, and because may not to any influence of file transmission It can be seen that.
Then, as shown in this example, the service of some applications may be negatively affected by frequently carrying out unconditional merging to cluster Quality, in some cases, it can be possible to unnecessarily interrupt in an uncontrollable manner.The embodiments described herein defines confession Wireless site (such as wireless site 106) is based at least partially on the next selectivity of reciprocity for merging the service provided within cluster (or conditionally) merge the method (and/or mechanism) of cluster.Such conditional merging can be further provided for for control pair Merge the mechanism of the influence of relevant service quality to possible cluster.
In some embodiments, transmittable (or broadcast) beacon of wireless site (for example, wireless site 106) is (for example, hair It is existing and/or synchronous) comprising the information about the service that wireless site (for example, as supplier and/or consumer) supports. In some embodiments, which can be included in the hash of all services of wireless site support (for example, service identifier (ID)) in.In some embodiments, which may specify for synchronous one or more parameters, for example, service ID, net Network title etc..
In some embodiments, wireless site can be based at least partially on the service of wireless site support to filter from right Deng the received beacon of (adjacent) wireless site.In other words, which can be based at least partially on whether received beacon wraps The information for the service supported about wireless site is included selectively to consider received beacon.In some embodiments, filtering letter Mark may include by wireless site support service and received beacon in be designated as support service between comparison (for example, nothing Local hash that line website generates and from the comparison between the received hash of reciprocity wireless site).For example, if wireless site (for example, via comparing) determines that reciprocity wireless device supports the service also supported by the wireless site, then the wireless site can be tasted Examination is synchronized to reciprocity wireless site.In such cases, cluster associated with wireless site and reciprocity wireless site can (at least portion Point) merged based on the service that public (or mutual) is supported.On the contrary, if wireless site (for example, via comparing) determines equity Wireless device does not support the service (for example, not having public support service within peer-to-peer) yet supported by the wireless site or at that When kind, then the wireless site can not be attempted to be synchronized to reciprocity wireless site.In such cases, with wireless site and reciprocity nothing The associated cluster of line website can be (at least partly) based on the service and nonjoinder for determining that no public (or mutual) is supported.
It may be noted that the service supported can be considered or currently just find, consume with wireless site, advertisement (advertise) And/or the service provided is associated.In other words, if wireless site does not come from searching, consumption, advertisement and/or offer currently The service pointed out in the beacon of equity wireless site associated with another cluster, then wireless site can decide not to initiate cluster merging (for example, wireless site may be selected not to be initiated as merging the process of the new anchoring main equipment of cluster selection and/or do not initiate to be synchronized to be directed to Merge the process of the new anchoring main equipment of cluster).In addition, if reciprocity wireless site is maintained in range and continues from reciprocity wireless Website receives beacon, then wireless site can based on it is new find (or consumption, advertisement and/or offer) indicate in received beacon The wireless site of service and/or matching by wireless site offer/searching/consumption/advertisement service (or multiple services) Indicate that the reciprocity wireless site of Additional Services is initiated cluster and merged in beacon.
For example, wireless site can be consumed by the service of reciprocity wireless site advertisement, however, if wireless site is current Service is not being found, then the wireless site, which may be based partly on, does not currently find the service of advertisement to determine and not initiate association cluster Merge.As another example, which just in consumption service and may can receive beacon, beacon instruction and another cluster Associated equity wireless device is currently look for the service consumed by the wireless site.In such cases, the radio station Point, which can be based at least partially on, to be found by reciprocity wireless site and is therefore the service that wireless site and reciprocity wireless site share Merge to initiate cluster.As another example, which can be capable of providing service, but can not actively advertisement clothes Business.However, the wireless site can be based at least partially on radio station when determining that reciprocity wireless site actively finds service The merging for being associated with cluster is initiated in the point service shared with reciprocity wireless site.As another example, which may be It provides and services and can receive beacon, beacon instruction reciprocity wireless device associated with another cluster is currently look for radio station The service that point provides.In such cases, which can be based at least partially on reciprocity wireless site and find and be therefore The service that wireless site and reciprocity wireless site share merges to initiate cluster.
In some embodiments, can be started based on one or more standards at wireless site for example, as described above Selectivity merge (or synchronous).In other words, if there is one or more standards at the wireless site, which can be with (or synchronous) can selectively be merged, and can alternatively be synchronized to reciprocity wireless site without considering wireless site and equity The service that wireless site is supported.For example, if the wireless site is currently providing and/or the application of consumer need low latency (for example, quality of service requirement with higher), then the wireless site can selectively merge (or synchronous), and if Wireless site does not provide currently and/or the application of consumer need low latency, then can disable selective merging.For example, if should Wireless site is providing and/or is consuming more high quality-of-service application, such as display/screen mirror image and/or video or voice Calling, then the wireless site can selectively merge.On the contrary, if the wireless site providing and/or consuming it is lower The application of service quality, then the wireless site can disable selective merging.
