Description

A kind of determine the method for trunking, website, access point, trunking and system

Technical field

The present invention relates to the communications field, a kind of determine the method for trunking, website, access point, trunking and system.

Background technology

IEEE(Institute for Electrical and Electronic Engineers at present, IEEE, Institute of Electrical and Electric Engineers) normal structure formulating 802.11ah specification, and propose access point overlay area and need to cover the demand of a kilometer, this distance being equivalent to cover the access point supported in a series of for existing IEEE802.11 specifications 100 meters expands 10 times, and two the typical application scenarios proposed for IEEE802.11ah specification are exactly intelligent meter data recording, sensor network.The feature of these application scenarios is:

(1) enormous amount of STA.Such as, in the region of radius 1 kilometer, in order to realize effectively detecting, the quantity needing the 802.11ah sensor disposed may be more than 6000.

(2) check meter application time, to data transmission and security requirement higher.Such as, it is ensured that higher success rate of checking meter, when ammeter is a lot, reduces the time of single ammeter busy channel, i.e. improve transfer rate.Meanwhile, malicious attack to be prevented, safety is proposed certain requirement.

(3) battery is powered, and in most cases, user is not easy to be replaced the battery of STA and safeguard.

According to existing Wireless Fidelity Wi-Fi(wireless-fidelity, Wi-Fi, Wireless Fidelity) specification, work in the site STA (Station, STA, website) of basic network pattern in uplink and downlink, be all with access point (Access Point, AP, access point) power consulted directly communicates with AP, and the distance between the transfer rate of data and STA and AP has substantial connection.Therefore it is deployed in the STA of diverse location in an AP coverage, is different from the speed of AP communication.As a rule, in identical channel model, with AP apart from remote STA, when communicating with AP, speed is less than with AP apart near STA.

At present, in IEEE802.11ah network, the definition about trunking (Relay, trunking) is also the clearest and the most definite.It is believed that be the third equipment being different from AP and STA；Someone is it is even contemplated that Relay is exactly AP；Also it is believed that Relay is the STA possessing forwarding capability.One Relay may service one or more STA.

Being forwarded by trunking, from AP, farther out or the poor STA of link-quality can shorten the time of data of sending to AP, i.e. improves throughput.Because each STA needs the data volume reported to be basically unchanged, the time that therefore sends shortens the electric quantity consumption that can effectively reduce STA.

Another kind of situation common in sensor network be the electricity of some STA less than a threshold value time, in order to extend working life, this STA creates the demand of relay services.At this moment, it is provided that Relay services, and can effectively extend the site works life-span.Further, if the appointment of Relay is carried out according to certain rule, each the site works life-span in whole network can be made roughly the same.Make battery altering work more effectively.

In prior art, a kind of method of Relay of discovery is, one associate with AP after STA, if there being relay services demand, this STA can to AP send one relaying find request Relay Discovery Request message.After AP receives this request message, broadcasting this request message in a network, and carry some additional informations, such as, carry condition message, the Relay i.e. meeting condition could respond this request；Or response message is directly issued STA or is forwarded by AP by the mode of prescribed response, i.e. Relay.In this method, when broadcast request message, in most cases, Relay is all in sleep state, thus decreases the scope finding Relay, and then last selected Relay is not necessarily optimum.

The knowledge of described whole network, such as, can be one or more in information of the loading condition (as trunking provides relay services for one or more websites) etc. of network topology information, network topological information or known trunking.

Described step 1320 is optional.

Step 1330 is: described access point broadcasts agreement wakeup message (the 3rd message), carrying the temporal information that described access point is specified in described 3rd message, at least one trunking that described 3rd message receives described 3rd message for instruction is in wake-up states in the time indicated by described temporal information.Described access point can broadcast described 3rd message according to described first message.Described first message can carry the identification information of described first website, described 3rd message can also carry the identification information of described first website.

Wherein, step 1320, the order of occurrence of 1330 can exchange, and can be i.e. that step 1320 occurs before step 1330, it is also possible to be that step 1330 occurs before step 1320, it is also possible to be step 1320, occur both 1330 simultaneously.Wherein said second message can also be sent by broadcast mode, described second message and the 3rd message can merge into a message, this message can carry the information entrained by described second message and the 3rd message simultaneously, now step 1320,1330 can also merge into a step.The order of occurrence of each step not considered critical in the present invention, can have different order of occurrence as required, single message is segmented into multiple message, and multiple message can also be merged into a message, all can be changed as required, this is not limited by the present invention.

Step 1340 is: described first website broadcasts relaying requirement message (the 4th message) in the time that described temporal information indicates.Described 4th message is used for asking relay services.Described 4th message can carry the identification information of described first website.

Step 1350 is: trunking (relays 1 ... relaying as illustrated in the drawing and n) relays update request message (the 6th message) according to described 4th message feedback to described access point.Described 6th message is for indicating the trunking sending described 6th message can provide relay services, further, can be that described first website provides relay services, the identification information that described first website can be carried and the identification information of the relaying sending described 6th message.In embodiment the most provided by the present invention, relaying 1 is described first relaying.

Step 1360 is: described access point receive at least one trunking according to described 4th message feedback give described access point the 6th message after, carry out relay selection according to the 6th message at least one described, from least one trunking described, be i.e. chosen as described first website the first trunking of relay services is provided.

Described access point can select an optimum trunking to provide relay services for described first website according at least to the above-mentioned information carried in the 6th message at least one described from least one trunking described.

Described access point is underway continue selection time, can also be according to the understanding of the current knowledge to whole network, as described in can include, the first website is to the distance etc. of each trunking, such that it is able to the comprehensive consideration to the factor such as network structure and link cost, an optimum trunking is selected to provide relay services for described first website from each trunking.

The trunking of described optimum can be meet in following condition one or more: other trunkings compared by this trunking, and its battery electric quantity is more sufficient, more preferably and/or described Uplink/Downlink cost is lower etc. for the data rate quality of reception higher, described supported.

Step 1370 is: described access point broadcasts relaying updating response information (the 8th message), carries the identification information of the first trunking, it is also possible to carry the identification information of described first website in described 8th message；Described first trunking for that selected from least one trunking described according at least to described 6th message by described access point, for described first website provide relay services trunking；Described 8th message may indicate that described first trunking is selected and provides relay services for described first website.

Step 1380 is: described first trunking confirms message according to described 8th message to the feedback relaying upgrading of described access point, and this message may indicate that described first trunking is confirmed as described first website and provided relay services.

Other are not chosen by described access point and provide the trunking of relay services into described first website, after described 8th message receiving the broadcast of described access point, can be to described access point feedback message, the first the most selected trunking feeds back one for the message confirmed to described access point, so can reduce unnecessary data transmission, save resource.

Step 1380 is optional.Described 5th message specifically can broadcasted the 8th message by described access point, and receive described first trunking according to described 8th message after the confirmation message that described access point feeds back, being sent to described first website, described 8th message is broadcasted after described access point receives described 6th message；Wherein, described 8th message carries the identification information of described first trunking, indicate described first trunking selected for described first website offer relay services.

Step 1390 is: described access point is after receiving the described relaying upgrading confirmation message that described first trunking sends, relaying assignment messages (the 5th message) is sent to described first website, described 5th message carries what described access point was selected from least one trunking described, the identification information of the first trunking of relay services is provided for described first website.

Described first website is after receiving described 5th message, it is possible to be known as the information of its trunking providing relay services, so that it is determined that provide the trunking of relay services for it.

Detailed process can be as described below:

First the STA having relay services demand sends a Relay Appointment Request message for inquiring whether AP now network can provide relay services to AP.AP decides whether to accept the request of STA and by sending Relay Appointment Response message informing STA to STA according to whole network knowledge at that time.If do not accepted, AP returns to the state before request, STA re-request the most immediately or after a while re-request, it is also possible to abandon request.If accepted, AP can carry the sending strategy of STA broadcast Relay Needed Frame message in RelayAppointment Response message, and i.e. with how high-power, many two-forties send.It addition, if AP accepts STA request, AP can be at a time (when that Relay waking up), it is common that the moment of AP broadcast beacon messages (Beacon), and what broadcast was arranged wakes up the moment up.What AP broadcasted wakes up agreement message up, may be embodied in Beacon message, it is also possible to be a single broadcast frame message.

STA wakes up the moment up agreement, the sending strategy broadcast Relay Needed Frame message provided with AP.Relay receive described message after, immediately to AP send Relay Promotion Request message.This message is carried the information for AP reference, the address of such as STA Yu Relay, this Relay receives the quality of reception Receive Quality of the Relay Needed Frame message of STA broadcast, STA Yu Relay each battery electric quantity, the speed of each self-supporting of STA Yu Relay, uplink downlink cost Uplink Cost/Downlink Cost of Relay to AP etc..

After AP receives first Relay Promotion Request, wait for a period of time for receiving the Relay Promotion Request message that other Relay send, or wait N number of Relay Promotion Request.After receiving, AP selects an optimum Relay to provide service for request STA.Optimum criterion is a lot, states in a particular embodiment.

AP broadcasts Relay Promotion Response message, comprises the address information of selected Relay and the time window adjustment information of Relay busy channel in message.

Selected Relay is not had to return to the state before relaying finds；The most selected Relay sends Relay Promotion Confirm message to AP.

After AP receives the confirmation message choosing Relay, to request STA send Relay Designation Frame, notice STA be its service be which Relay, and the time window adjustment information of STA busy channel.

Once AP assigns Relay success for request STA, and the data of STA are forwarded by Relay until Relay no longer provides service for this STA afterwards.

For STA, its method flow can be as described below:

STA has the demand of relay services, starts once to relay discovery procedure, sends a Relay Appointment Request message to AP.Then the response of AP is waited.If within a period of time, it will usually set by intervalometer, not receiving the Relay Appointment Response message of AP, STA thinks that this time discovery procedure is failed, returns to relay the state before discovery procedure.If receiving Relay Appointment Response message, and carry in message is the decision of refusal request, and STA thinks this time discovery procedure failure, returns to relay the state before discovery procedure.If receive is the Relay Appointment Response message accepting request, STA continues relaying discovery procedure and receives the trunking discovery strategy carried in this response message, i.e. with how high-power, many two-forties broadcast Relay Needed Frame in a network.Wherein, speed can change by the way of change is modulated and encoded.

Then, STA receive AP broadcast wake up the moment up, i.e. can broadcast the moment of Relay Needed Frame.Relay Needed Frame carries the address information of STA, the battery level information of STA, optionally includes the speed that STA supports, the uplink downlink quality etc. between STA and AP.After STA receives the wakeup message of AP broadcast, can select to sleep to waking up the moment up, the strategy broadcast Relay Needed Frame be given in advance with AP the most in a network.After broadcast, STA enters waiting state, and opening timing device.

STA waits that the relaying assignment messages Relay Designation Frame. of AP transmission is when intervalometer overflows, if STA does not receive this message, STA thinks that the discovery procedure of current relaying is failed, return to relay the state before discovery procedure, it can be the process re-starting the most again and once relaying discovery, a period of time can also be waited once to relay discovery procedure re-starting, or abandon relaying and find.If before intervalometer overflows, STA receives in Relay Designation Frame and message and does not carry Relay address, or one for indicating failed address, such as complete " 1 ", STA thinks that the discovery procedure of current relaying is failed, returns to relay the state before discovery procedure, can be the process re-starting and once relaying discovery, a period of time can also be waited once to relay discovery procedure re-starting, or abandon relaying and find.If before intervalometer overflows, STA receives in Relay Designation Frame and message and carries Relay address, and STA obtains AP and is assigned to its Relay address, now also comprises the adjustment information of the time window of STA busy channel in message.

For AP, its method flow can be as described below:

Once relaying in discovery procedure, AP is to start from the Relay Appointment Request message receiving STA transmission.After receiving Relay Appointment Request, AP is it is first determined whether this acceptance request, and the reason of refusal request can have:

STA has been assigned in a Relay, or network has not had the unnecessary Relay etc. that can provide service.

If AP refuses request, AP can send Relay Appointment Response message informing STA, it is also possible to does not send any message and does not sends to STA(, may be considered that refusal).

If AP receives request, AP can determine whether the strategy of the broadcast Relay Needed Frame of STA.Such as, when STA is to initiate relaying discovery procedure for the first time, AP can allow STA find according to going up a discovery strategy finding successful STA recently, or AP allows STA think that optimum discovery strategy carries out relaying and finds according to AP.If the last relaying discovery procedure of STA is failed, AP can allow STA with relatively low speed broadcast Relay Needed Frame, or allows STA with higher power broadcasts Relay Needed Frame, or both have concurrently.The strategy that AP formulates passes to STA by Relay Appointment Response message.

Accept after the request Concurrency of STA send Relay Appointment Response message, AP selects the moment (only AP knows this moment) that all STA can wake up, it is typically some Beacon moment (because all of STA can monitor Beacon, although not necessarily each Beacon monitors.), broadcast the wakeup time of an agreement.This broadcast is typically Beacon frame.All of STA can wake up in the moment that wakes up up of agreement.

After AP has broadcasted the message that agreement wakes up the moment up, enter waiting state, and opening timing device.When intervalometer overflows, without receiving any Relay Promotion Request message, AP thinks that the discovery procedure of current relaying is failed, and AP returns to relay the state before discovery procedure.If before intervalometer overflows, receiving a Relay Promotion Request message, AP can select the Relay Promotion Request message waited for a period of time for receiving other Relay, or AP waits until and receives N number of message.If AP selects the mode of counting, it is also desirable to start an intervalometer.If intervalometer overflows, the most do not receive N number of message, can enter into next step yet and select link.

After receiving the Relay Promotion Request message that one or more Relay sends, one optimum Relay of the whole network knowledge-chosen that AP grasps according to the information in each Relay message and AP.Such as, optimum Relay can be provided that the highest throughput, or the Relay of optimum can be provided that the time the longest (electricity is the most sufficient) of relay services, or the Relay of most lightly loaded etc..After selected Relay, AP broadcasts Relay Promotion Response message, carries the address information choosing Relay, choose the adjustment information of the time window of the busy channel of Relay in message.AP waits the confirmation message choosing Relay, Relay Promotion Confirm, and starts intervalometer.

If when intervalometer overflows, AP does not receive the Relay Promotion Confirm message choosing Relay to send, or before intervalometer overflows, AP receives the Relay Promotion Confirm message carrying refusal decision choosing Relay to send, and AP thinks that this relaying does not accept appointment.AP can select to re-broadcast Relay Promotion Response message, carries alternative Relay(suboptimum Relay in message) address information and the adjustment information of its busy channel time.Without alternative Relay, AP thinks that current relaying finds unsuccessfully, returns to the state before relaying finds.

After AP receives the Relay Promotion Confirm accepting to assign choosing Relay, send Relay Designation Frame message to STA, message is carried the address information of the Relay being assigned to it, the adjustment information of the time window of the busy channel of STA.

For Relay, its method flow can be as described below:

Once relaying in discovery procedure, Relay is from hearing that the agreement message that wakes up up that AP broadcasts starts.The moment that Relay arranges at AP wakes up, and receives the Relay Needed Frame that STA sends.Return to relay the state before discovery procedure without receiving Relay Needed Frame, Relay.

After Relay receives Relay Needed Frame, Relay Promotion Request message can be sent immediately to AP, message carries the address of STA Yu Relay, this Relay receives the quality of reception Receive Quality of the Relay Needed Frame message of STA broadcast, STA Yu Relay each battery electric quantity, the speed of each self-supporting of STA Yu Relay, uplink downlink cost Uplink Cost/Downlink Cost of Relay to AP etc..

Relay waits the Relay Promotion Response message of AP, and opening timing device.If when intervalometer overflows, Relay does not receive Relay Promotion Response message, or before intervalometer overflows, it is not oneself that Relay receives the Relay that in Relay Promotion Response and this message, AP assigns.In above-mentioned two situations, Relay thinks oneself do not have selected, returns to relay the state before discovery procedure.

After selected Relay receives the Relay Promotion Response of AP, if acceptance appointment, adjust the time window of busy channel according to the information carried in Relay Promotion Response message, and send Relay Promotion Confirm Accept message to AP.If not accepting appointment, send Relay Promotion Confirm Reject message to AP.
