NAN mechanism is briefly described first, close on sensing network (Neighbor Awareness Network, Abbreviation NAN) mechanism be Wireless Fidelity Wi-Fi Alliance work out a standard, the effect of this standard is in no central node In the case where, so that all equipment (i.e. NAN equipment) synchronization onwards for participating in NAN mechanism are come, in the discovery time of NAN mechanism agreement Maintenance work and service discovery work, the service discovery that NAN mechanism is carried out in window (Discovery Window, abbreviation DW) are i.e. logical Cross the realization of transmission service discovery frame (Service Discovery Frame, abbreviation SDF) message, the service discovery frame message Including query messages or broadcast message.Equipment can establish corresponding connection based on the information obtained in service discovery, then into The transmission of row data.

Specifically, can be discovery channel with the 6th channel in NAN mechanism in the standard that Wi-Fi Alliance is specified, On 6th channel, for each cluster, the duration of discovery time window DW is fixed, and two DW of the arbitrary neighborhood of the cluster Between time interval be also fixed.

In NAN mechanism, setting is found window (discovery window, DW), and NAN equipment can be taken in DW Business discovery.It is provided with a DW in general every 512 TU (time unit, time quantum) of NAN mechanism, one of TU's holds Continuous duration is about that the duration of 1024 μ s, DW is generally 16TU, i.e., in NAN mechanism, generally every 496 TU settings one A DW.In NAN mechanism, one cluster Cluster (also known as adjacent to sensing network) of one or more NAN equipment formation, one Cluster enter DW when, by the Cluster be in host node (master), anchor host node (anchor master, AM), And the NAN of host node (non-master synchronization, non-master sync) state for being responsible for synchronization etc. is set Preparation send sync beacon frame (sync beacon) message, the information of the AM in the Cluster is carried in the message, for connecing The NAN equipment for receiving the message is synchronous with the AM realization in the Cluster.

Illustratively, as shown in Figure 1, being the schematic diagram of the DW of a cluster, according to the standard that Wi-Fi Alliance is formulated, in DW In, the NAN equipment in the cluster can send service discovery frame SDF message in DW, carry out service discovery, the time other than DW In, the NAN equipment in the cluster can send discovery beacon (discovery beacon) message, to declare the presence of the cluster.Cluster In each NAN equipment service discovery can be carried out in DW, to find that other NAN that can carry out data transmission with it are set It is standby.After service discovery, at least two NAN equipment for needing to carry out data transmission between each other can arrange in the DW Running time-frequency resource and internetwork connection mode, and after the DW, according to the network connection side of agreement on the running time-frequency resource of agreement The NAN network of the corresponding non-stop layer node of formula component.

The process that NAN equipment completes service discovery is as follows:

1, after a device activation NAN function (after becoming NAN equipment), itself can be set to AM, creates one Cluster, and set the Cluster's based on the MAC of itself (Media Access Control, medium access control) address Cluster identity (Identity, ID) value, sets time synchronization function TSF to the integral multiple of 512TU.

Once 2, the NAN equipment receives the Beacon frame that the NAN equipment from one or more other Cluster is sent When (i.e. sync beacon is collectively referred to as Beacon frame below), so that it may judge whether oneself will be added the Cluster of other side.

In Beacon frame, the information of corresponding Cluster is generally carried, specifically can be in corresponding Cluster AM information, such as may include anchor host node grade (anchor master rank, AMR), host node grade (master Rank, MR), host node priority (Master Preference, MP), anchor host node priority (anchor Master Preference, AMP), enchancement factor (random factor, RF), anchor host node signal transmission time (Anchor Master Beacon Transmission Time, AMBTT), time synchronization function (time synchronization function, TSF), one of Cluster ID and cluster grade (Cluster grade, CG) or a variety of.

The information of the AM of Cluster belonging to oneself can be sent to it by sending Beacon frame by one NAN equipment His NAN equipment, equally, a NAN equipment also can receive the transmission of the NAN equipment in this Cluster or other Cluster Beacon frame.

After NAN equipment receives a Beacon frame, it can be determined that the Beacon frame is belonging to itself NAN equipment in the Cluster still NAN equipment in other Cluster, if the NAN in other Cluster is set Standby, then the NAN equipment may determine that whether the value of the cluster grade CG in received Beacon frame is greater than the cluster grade CG's of itself Value, if more than then the corresponding Cluster of the received Beacon frame is added in the NAN equipment, and otherwise, which, which does not do, locates Reason.This completes the polymerizations of NAN equipment, that is, the higher Cluster of value of cluster grade CG can be added in NAN equipment.

If 3, judging, the Cluster of other side will be added in determination, be added other side Cluster after with addition AM in Cluster, which is realized, to be synchronized, in the Cluster that specifically can be the parameters information and addition in the AM by itself AM is synchronous, such as itself original time synchronization function TSF is updated to the TSF etc. of the AM in the Cluster being added.

4, after synchronization, when the DW of the Cluster of addition arrives, which sends SDF (Service in DW Discovery Frames, service discovery frame) message to carry out service discovery, can for example carry in the SDF message and be used for Service-seeking (Service Subscription) information of service needed for inquiry, or can for example carry for issuing this (Service Publish) information is issued in the service for the service that NAN equipment is capable of providing, other NAN equipment are receiving this NAN equipment send SDF message after, however, it is determined that meet the SDF message, Service Matching can be carried out, then can in DW to The NAN device replied SDF message.

Likewise, in DW, the NAN equipment may also can receive the transmission of other NAN equipment for carrying out service hair Existing SDF message, if the NAN equipment, which determines, meets the received SDF message of institute, which also can be in DW to corresponding NAN device replied SDF message.
