In addition, the first equipment can send carry instruction discovery window and vocational window service announcement information, with At least one equipment arranges the discovery window and vocational window of the service groups；Or first equipment can send and carry finger Show the service announcement information of discovery window, vocational window is then informed at least one described equipment in discovery window；Or First equipment, which is sent, carries the service announcement information that window is negotiated in instruction, in negotiating window and at least one described equipment First addition service groups equipment hold consultation, obtain the discovery window and vocational window of service groups.

It should be noted that each equipment in NAN can use multiple business, multiple industry that each equipment uses simultaneously Business may not be identical again, therefore an equipment can be added multiple service groups simultaneously, multiple in each service groups to set It is standby to use identical services.In addition, a discovery window and at least one vocational window corresponding with the discovery window can be one A business processing period, the discovery window of service groups can be exactly that (the the such as the 1st, 2,3,4 ... ... waits DW window for the DW window of each NAN Mouth is all the discovery window of service groups), it is also possible to the DW window for having certain intervals NAN, interval can be 1 DW window of NAN Mouthful (the the such as the 1st, 3,5,7 ... ... wait windows be the discovery window of service groups), 2 DW windows (such as the of interval or NAN Isosorbide-5-Nitrae, 7,10 ... ... wait windows for the discovery window of service groups), or the DW window of NAN etc. of interval other quantity.Business The vocational window of group can be obtained by each discovery window by the offset of preset time and/or channel, find window and business Window can also find that the duration of window and vocational window can be according to business in different channels in identical channel The processing time is determined.Such as: a discovery window is defined every 512ms or 1024ms first, is then found in every two Vocational window is defined in the time interval of window, it is found that the duration of window and vocational window can be 16ms；It can also be entire A discovery window and a vocational window are defined in traffic handling time.

S102, when first equipment determines at least one target device transmission data into the service groups and is believing When the wake-up notice that any one equipment being not received by least one described equipment in road competition process is sent, described first Equipment sends at least one described equipment in the discovery window and wakes up notice, so that in not at least one described equipment The equipment of dormancy state is switched to wake-up states when reaching the vocational window, so that at least one described equipment is described in the arrival Wake-up states are in when vocational window, and then first equipment in the vocational window and is in described in wake-up states extremely A few target device carries out data transmission.

In the specific implementation, first equipment is identified according to the service groups, the industry is sent by wake-up notice At least one described equipment in business group.Since each equipment in NAN can be added multiple groups simultaneously, the first equipment hair The wake-up notice for carrying service groups mark is sent, can identify according to service groups, which will wake up notice, is sent to specified service groups. Wherein, waking up notice can be service discovery frame, and service groups mark can be placed in the first address of service discovery frame, first Equipment can will wake up notice and be sent directly to specified service groups；Service groups mark can also be placed on the of service discovery frame In three addresses, and broadcast address or specific multicast address are placed in the first address, the equipment in specified service groups is received To after wake-up notice, it can be confirmed that wake-up notice is destined to oneself according to third address, and other service groups are received To after waking up notice, it can be confirmed that service groups mark is not one's own；Service groups mark can also be with information element Form is placed in wake-up notice, after the equipment of specified services group receives wake-up notice, can know this by the information element It wakes up notice and is intended for oneself.

Wherein, service groups mark can be the MAC (Medium Access Control, media access control layer) of equipment Address or other identifier, such as Business Name, class of service or the MAC Address of service groups, Business Name, class of service process fortune Value after calculation etc..The equipment of equipment or first lookup business that service groups mark can provide business by first mentions For, such as: equipment A provides music service, and other equipment discovery is waited in NAN, and equipment B searches music service. Equipment B has found equipment A by the service discovery mechanisms of NAN, and then equipment B and equipment A establishes a service groups, and equipment A will The MAC Address of equipment A is sent to equipment B, equipment A and equipment B and identifies simultaneously using the MAC Address of equipment A as service groups.Or The MAC Address of equipment B can be sent to equipment A, equipment A and equipment B simultaneously using the MAC Address of equipment B as business by equipment B Group mark.When the other equipment such as equipment C, equipment D are added to service groups, service groups can be identified group by equipment A or equipment B Other equipment are sent to, all devices in service groups have at this time and only same service groups identify.

Optionally, in the first equipment after the discovery window sends wake-up notice at least one described equipment, and When reaching vocational window by period, paging window of first equipment in the vocational window is to the target Equipment sends paging message, sets so that the target device receives described first in the transmission window according to the paging message The data that preparation is sent.Wherein, vocational window includes paging window and transmission window.In addition, when certain at least one above-mentioned equipment A/a little equipment is not received by the paging message of any one of service groups equipment transmission in paging window and oneself does not count According to it is to be sent when, this some/a little equipment can be switched to dormant state from wake-up states when reaching transmission window, to play The effect of power saving.In the specific implementation, the first equipment has sent wake-up notice in discovery window, service groups belonging to the first equipment All devices can receive this and wake up notice, and then they wake up according to this and notify, in the paging of corresponding vocational window It all wakes up in window, then the equipment inside entire service groups needs to carry out mutual paging according to what data were transmitted, has and is sought The equipment exhaled can wait data to be received in next transmission window, page others' equipment in next transmission Window can send data.When actual use, service groups any and an equipment can be the first equipment, as long as It, which can be competed, has sent wake-up notice.Due to being that competition is sent, so the other equipment ratio in discovery window, in service groups As the second equipment can only also receive the wake-up notice of the first equipment transmission.In the paging window of vocational window, first is set The standby target device that can page it, other equipment can also page their corresponding target devices.Certainly, the first equipment can also To be paged.That is, the effect that this scheme reaches is exactly that any one equipment preparation will be to some other in service groups Or certain equipment, when send business datum, it can first send a wake-ups notice, notice business in discovery window All devices in group, all in wake-up states, can be in the paging window of vocational window and be originally dormant state, then Wake-up states are switched to, are also possible to be always maintained at wake-up states, then these equipment are mutually paged as needed, are connect down Transmitted again, as long as and the equipment in discovery window in service groups there is one have sent wakeup message, others are set It is standby there is no need to retransmit wake-up to be notified of, as long as the paging window to corresponding vocational window is waken up.

Optionally, wake-up notice is encrypted in the first equipment；First equipment is by described by encrypting The wake-up notice of processing is sent at least one described equipment.Wherein, the key of encryption can also be by first offer industry The equipment of the equipment of business or first lookup business provides.

Optionally, waking up notice may include service announcements position table, after service announcements position table is used to indicate vocational window Multiple vocational windows are in wake-up states to carry out data transmission in above-mentioned multiple vocational windows in wake-up states.Such as: Service announcements position table can be 8 binary codes, continuous 8 vocational windows after indicating discovery window, if 8 binary codes Value is 01100111, then it represents that is carried out data transmission in the 2nd, 3,6,7,8 vocational window, at least one above-mentioned equipment receives this After the table of service announcements position, when reaching the vocational window of service announcements position table instruction every time in wake-up states.

Further, the first equipment in the discovery window in a manner of competitive channel resource at least one described equipment It sends and wakes up notice.Competitive channel resource mode is as follows: using carrier sense multiple access conflict avoidance CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism, it is reached when listening to idle time of channel When the predetermined time, as soon as starting to be kept out of the way with the random number generated, random number is subtracted 1 every preset time interval, when It when random number is kept to 0, sends wake up notice immediately, channel operating status is numerous if monitoring when random number fails to be reduced to 0 It is busy, then suspend and reduce the random number, when listening to the idle time of channel arrival predetermined time again, continues just to subtract random number 1.In CSMA/CA mechanism implementation procedure, if the first equipment receives the wake-up notice that at least one above-mentioned equipment is sent, the One equipment does not retransmit wake-up notice.

As long as at least one of the business is set it should be noted that the first equipment of service groups has sent wake-up notice It is standby to be no longer needed for sending wake-up notice.In addition, the first equipment is sent at least one equipment after waking up notice, can switch It can also be stayed awake for dormant state, some at least one above-mentioned equipment/a little equipment are determined into the service groups Target device send data but do not obtain channel resource during channel competition and send to wake up notice, therefore this certain A/a little equipment can all be switched to dormant state after discovery window reception to wake-up notice, can also keep waking up shape State；Some at least one above-mentioned equipment/a little equipment does not have data transmission to simply wait for receiving possible data, therefore this certain A/a little equipment can keep dormant state after discovery window reception to wake-up notice, when reaching vocational window, business All devices in group are in wake-up states.

In embodiments of the present invention, pass through the first equipment in neighbouring sensing network and the first equipment support identical services At least one equipment establishes service groups, and discovery window and vocational window at least one equipment agreement service groups；When One equipment determines that the target device into service groups sends data and is not received by least one during channel competition and sets When the wake-up notice that preparation is sent, the first equipment sends at least one equipment in discovery window and wakes up notice, so that at least one Equipment in equipment in a dormant state is switched to wake-up states when reaching vocational window, so that at least one equipment reaches It is in wake-up states when vocational window to carry out data transmission in vocational window, to improve the efficiency of data transmission, subtracts Small power consumption.
