Description

A kind of method of definite trunking, website, access point, trunking and system

Technical field

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

Background technology

Present IEEE(Institute for Electrical and Electronic Engineers, IEEE, Institute of Electrical and Electric Engineers) normal structure is being formulated the 802.11ah standard, and proposition access point overlay area need to cover the demand of a kilometer, this distance that is equivalent to 100 meters of the access point that will support in a series of standards of existing IEEE802.11 coverings has enlarged 10 times, and be exactly intelligent meter data recording for two typical application scenarioss of IEEE802.11ah standard proposition, sensor network.The characteristics of these application scenarioss are:

(1) enormous amount of STA.For example, in the zone of 1 kilometer of radius, in order to realize effective detection, need the quantity of the 802.11ah transducer of disposing possibly over 6000.

(2) while checking meter application, higher to transfer of data and security requirement.For example, guarantee the higher success rate of checking meter, when ammeter is a lot, reduce the time of single ammeter busy channel, namely improve transmission rate.Simultaneously, prevent malicious attack, fail safe is proposed to certain requirement.

(3) powered battery, and in most cases, the user is not easy to the battery of STA is changed and safeguarded.

According to existing Wireless Fidelity Wi-Fi(wireless-fidelity, Wi-Fi, Wireless Fidelity) standard, 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 of consulting is directly communicated by letter with AP, and between the transmission rate of data and STA and AP apart from substantial connection is arranged.Therefore being deployed in the STA of diverse location in an AP coverage, is different from the speed that AP communicates by letter.As a rule, in identical channel model, with the STA of AP distance, speed is lower than the STA with the AP near distance when with AP, communicating by letter.

At present, in the IEEE802.11ah network, also not clear and definite about the definition of trunking (Relay, trunking).Someone thinks to be different from the third equipment of AP and STA; Someone thinks that even Relay is exactly AP; Also someone thinks that Relay is the STA that possesses forwarding capability.A Relay may serve one or more STA.

By trunking, forward, from AP away from or the poor STA of link-quality can shorten the time that sends data to AP, namely improved throughput.Because the data volume that each STA need to report is substantially constant, so transmitting time shortens the electric quantity consumption that can effectively reduce STA.

Another kind of in sensor network common situation be the electric weight of some STA during lower than a threshold value, in order to extend working life, this STA has produced the demand of relay services.At this moment, provide the Relay service, can effectively extend the site works life-span.Further, if the appointment of Relay is carried out according to certain rule, can make each the site works life-span in whole network roughly the same.Make battery altering work more effective.

In prior art, the method for Relay of discovery a kind of is, one with STA after AP is associated, if the relay services demand is arranged, this STA can send a relaying to AP and find request Relay Discovery Request message.After AP receives this request message, this request message of broadcast in network, and carry some additional informations, and for example carrying condition message, the Relay that namely satisfies condition could respond this request; The perhaps mode of prescribed response, namely Relay directly issues response message STA or forwards by AP.In this method, when broadcast request message, in most cases, Relay is in sleep state, thereby has reduced the scope of finding Relay, and then last selected Relay is not necessarily optimum.

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

Described step 1320 is optional.

Step 1330 is: agreement wakeup message (the 3rd message) of described access point broadcast, in described the 3rd message, carried the temporal information of described access point appointment, described the 3rd message is used to indicate at least one trunking that receives described the 3rd message and is in wake-up states in the indicated time of described temporal information.Described access point can be broadcasted described the 3rd message according to described the first message.In described the first message, can carry the identification information of described the first website, in described the 3rd message, also can carry the identification information of described the first website.

Wherein, step 1320,1330 order of occurrence can exchange, and can be namely before step 1320 occurs in step 1330, can be also before step 1330 occurs in step 1320, can be also step 1320,1330 both occur simultaneously.Wherein said the second message also can send by broadcast mode, described the second message and the 3rd message can be merged into a message, in this message, can carry simultaneously described the second message and the entrained information of the 3rd message, this moment, step 1320,1330 also can be merged into a step.In the present invention, the order of occurrence of each step does not strictly limit, different order of occurrence can be arranged as required, and single message can be divided into a plurality of message, and a plurality of message also can be merged into a message, all can change as required, the present invention does not do restriction to this.

Step 1340 is: described the first website is in the time of a described temporal information indication broadcast relaying requirement message (the 4th message).Described the 4th message is for asking relay services.In described the 4th message, can carry the identification information of described the first website.

Step 1350 is: trunking (relaying 1 as shown in FIG. ... relaying n) according to described the 4th message feedback, give described access point relaying upgrade request message (the 6th message).Described the 6th message is used to indicate the trunking that sends described the 6th message can provide relay services, further, can, for described the first website provides relay services, the identification information of described the first website and the identification information of the relaying that sends described the 6th message can have been carried.Wherein in embodiment provided by the present invention, relaying 1 is described the first relaying.

Step 1360 is: described access point is after receiving at least one trunking and giving the 6th message of described access point according to described the 4th message feedback, according at least one described the 6th message, carry out relay selection, namely from described at least one trunking, being chosen as the first trunking that described the first website provides relay services.

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

Described access point is underway to continue while selecting, can also be according to the understanding of current knowledge to whole network, as the first website as described in can comprising to the distance of each trunking etc., thereby can, comprehensively to the consideration of the factors such as network configuration and link cost, from each trunking, selecting the trunking of an optimum, for described the first website, provide relay services.

The trunking of described optimum can be in meeting the following conditions one or more: this trunking is compared other trunkings, and the better and/or described Uplink/Downlink cost of its battery electric quantity higher, described quality of reception of data rate more sufficient, that support is lower etc.

Step 1370 is: described access point is broadcasted a relaying updating response information (the 8th message), in described the 8th message, has carried the identification information of the first trunking, can also carry the identification information of described the first website; Described the first trunking for by described access point at least according to the trunking of described the 6th message from selecting described at least one trunking, relay services is provided for described the first website; Described the 8th message can indicate that described the first trunking is selected provides relay services for described the first website.

Step 1380 is: described the first trunking is according to described the 8th message to described access point feedback relaying upgrading acknowledge message, and this message can be indicated described the first trunking to confirm as described the first website relay services is provided.

Other are not chosen by described access point the trunking that relay services is provided for described the first website, after described the 8th message that receives described access point broadcast, can be to described access point feedback message, only has the first selected trunking to described access point, feeding back the message for confirming, can reduce unnecessary transfer of data, saving resource like this.

Step 1380 is optional.Described the 5th message can specifically broadcasted the 8th message by described access point, and receive described the first trunking according to described the 8th message after the confirmation message of described access point feedback, send to described the first website, described the 8th message is broadcasted after described access point receives described the 6th message; Wherein, in described the 8th message, carried the identification information of described the first trunking, indicated that described the first trunking is selected provides relay services for described the first website.

Step 1390 is: described access point is after receiving the described relaying upgrading acknowledge message of described the first trunking transmission, to described the first website, send relaying assignment messages (the 5th message), in described the 5th message, carried described access point from what described at least one trunking, select, the identification information of the first trunking of relay services is provided for described the first website.

Described the first website, after receiving described the 5th message, just can be known as the information that it provides the trunking of relay services, thereby is defined as the trunking that it provides relay services.

Detailed process can be as described below:

There is the STA of relay services demand at first to Relay Appointment Request message of AP transmission, to be used for inquiring AP whether network this moment can provide relay services.AP determines whether to accept the request of STA and passes through to send Relay Appointment Response message informing STA to STA according to whole network knowledge at that time.If do not accept, AP turns back to the state before request, and STA is request or request again again after a while immediately as required, also can discard request.If accept, AP can carry the sending strategy of STA broadcast Relay Needed Frame message in RelayAppointment Response message, and namely with much power, many two-forties send.In addition, if AP accepts the STA request, AP is (when Relay wakes up) at a time, and normally the moment of AP broadcast beacon messages (Beacon), what broadcast was arranged wakes up constantly.AP broadcast wake agreement message up, can be included in Beacon message, can be also an independent broadcast frame message.

STA wakes up constantly agreement, with the sending strategy that AP provides, broadcasts Relay Needed Frame message.Relay receive described message after, to AP, send Relay Promotion Request message immediately.In this message, carry the information for the AP reference, the address of STA and Relay for example, this Relay receives the quality of reception Receive Quality of the Relay Needed Frame message of STA broadcast, STA and Relay be battery electric quantity separately, the speed of STA and each self-supporting of Relay, Relay is to uplink downlink cost Uplink Cost/Downlink Cost of AP etc.

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

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

Do not have selected Relay to get back to relaying and find state before; Only have selected Relay to send Relay Promotion Confirm message to AP.

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

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

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

STA has the demand of relay services, starts a relaying discovery procedure, to AP, sends a Relay Appointment Request message.Then wait for the response of AP.If within a period of time, usually can set by timer, do not receive the Relay Appointment Response message of AP, STA thinks that this time discovery procedure is failed, turns back to relaying discovery procedure state before.If receive Relay Appointment Response message, and what in message, carry is the decision of refusal request, and STA thinks this time discovery procedure failure, turns back to the state before the relaying discovery procedure.If what receive is the Relay Appointment Response message that accepts request, STA continues the relaying discovery procedure and receives the trunking discovery strategy that carries in this response message, namely with much power, many two-forties are broadcasted Relay Needed Frame in network.Wherein, speed can be modulated and the mode of encoding changes by change.

Then, STA receives waking up constantly of AP broadcast, the moment that namely can broadcast Relay Needed Frame.The address information of carrying STA in Relay Needed Frame, the battery electric quantity information of STA, optionally comprise the speed that STA supports, the uplink downlink quality between STA and AP etc.After STA receives the wakeup message of AP broadcast, can select sleep to waking up constantly, the strategy broadcast Relay Needed Frame that then provides in advance with AP in network.After broadcast, STA enters wait state, and the opening timing device.

STA waits for that the relaying assignment messages Relay Designation Frame. of AP transmission is when timer overflows, if STA does not receive this message, STA thinks that current relaying discovery procedure is failed, turn back to relaying discovery procedure state before, it can be the process that re-starts again at once a relaying discovery, also can wait a period of time re-starting a relaying discovery procedure, or abandon relaying and find.If before timer overflows, STA receives in Relay Designation Frame and message and does not carry the Relay address, or address that is used to indicate failure, for example complete " 1 ", STA thinks that current relaying discovery procedure is failed, turns back to relaying discovery procedure state before, can be the process that re-starts again at once a relaying discovery, also can wait a period of time re-starting a relaying discovery procedure, or abandon relaying and find.If before timer overflows, STA receives in Relay Designation Frame and message and carries the Relay address, and STA has obtained the Relay address that AP is assigned to it, in message, also comprises the adjustment information of the time window of STA busy channel this moment.

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

In a relaying discovery procedure, AP is from receiving that the Relay Appointment Request message that STA sends starts.After receiving Relay Appointment Request, at first AP judges whether that this accepts request, and the reason of refusal request can have:

STA has been assigned a Relay, or in network, there is no the unnecessary Relay that service can be provided etc.

If AP refuses request, AP can send Relay Appointment Response message informing STA, also can not send any message and not send and can be considered to refusal to STA().

If AP receives request, AP can determine the strategy of the broadcast Relay Needed Frame of STA.For example, when STA is while initiating for the first time the relaying discovery procedure, AP can allow STA find according to a recently upper discovery strategy of finding successful STA, or AP allows STA think that according to AP optimum discovery strategy carries out the relaying discovery.If the last relaying discovery procedure of STA is failed, AP can allow STA with lower speed broadcast Relay Needed Frame, or allows STA with higher power broadcast Relay Needed Frame, or both have concurrently.The strategy that AP formulates passes to STA by Relay Appointment Response message.

After the request Concurrency of accepting STA send Relay Appointment Response message, the moment (only having AP to know that this constantly) that AP selects all STA can wake up, normally some Beacon are constantly (because all STA can monitor Beacon, although not necessarily each Beacon monitors.), the wakeup time of an agreement of broadcast.This broadcast is the Beacon frame normally.All STA can wake up waking up of agreement constantly.

After AP has broadcasted agreement and wakes message constantly up, enter wait state, and the opening timing device.In timer overflowed, if do not receive any Relay Promotion Request message, AP thought current relaying discovery procedure failure, and AP turns back to the state before the relaying discovery procedure.If before timer overflows, receive a Relay Promotion Request message, AP can select to wait for a period of time to receive the Relay Promotion Request message of other Relay, or AP waits for until receive N message.If AP selects the mode of counting, also need to start a timer.If timer overflows, still do not receive N message, also can enter into next step and select link.

After receiving the Relay Promotion Request message that one or more Relay send, AP is according to the Relay of an optimum of the whole network knowledge-chosen of the information in each Relay message and AP grasp.For example, optimum Relay may provide the highest throughput, or optimum Relay may provide the time the longest (electric weight is the most sufficient) of relay services, or the lightest Relay of load etc.After selected Relay, AP broadcast Relay Promotion Response message, carry the address information of choosing Relay in message, chooses the adjustment information of time window of the busy channel of Relay.AP waits for the confirmation message of choosing Relay, Relay Promotion Confirm, and start timer.

In if timer overflows, AP does not receive the Relay Promotion Confirm message of choosing Relay to send, before perhaps timer overflows, AP receives and chooses the Relay Promotion Confirm message that refusal determines of carrying that Relay sends, AP to think that this relaying do not accept appointment.AP can select again to broadcast Relay Promotion Response message, in message, carries alternative Relay(suboptimum Relay) address information with and the adjustment information of busy channel time.If there is no alternative Relay, AP thinks that current relaying finds unsuccessfully, turns back to the state of relaying before finding.

After AP receives the Relay Promotion Confirm of the acceptance appointment of choosing Relay, to STA, send Relay Designation Frame message, in message, carry the address information of the Relay that is 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:

In a relaying discovery procedure, Relay starts from the agreement message of waking up of hearing AP broadcast.Relay woke up in the moment of AP agreement, received the Relay Needed Frame that STA sends.If do not receive Relay Needed Frame, Relay turns back to the state before the relaying discovery procedure.

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

Relay waits for the Relay Promotion Response message of AP, and the opening timing device.In if timer overflows, Relay does not receive Relay Promotion Response message, or before timer overflowed, Relay received that the Relay that in Relay Promotion Response and this message, AP assigns is not oneself.In above-mentioned two situations, Relay thinks oneself do not have selectedly, turns back to the state before the relaying discovery procedure.

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