Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those skilled in the art are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

In order better the scheme that the embodiment of the invention provided to be described.Below will carry out schematic illustration to relevant technology.

According to existing 802.11 standards; (STA Station) can find access point through scanning, after having found access point for user terminal such as WiFi application terminal; User terminal can carry out authentication and related to connect with access point; Thereby add the WiFi network, promptly add WLAN (WLAN, Wireless Local Area Network).Wherein, A WLAN only uses a wireless channel, and this wireless channel confirmed by access point, and; The use of this wireless channel is also controlled by access point, and all user terminals in the network can occupy channel and use channel through contention or in the mode of access point poll.Wherein, the mode of user terminal scanning discovery access point mainly is divided into drive sweep and active scan, as follows:

Drive sweep: access point periodic broadcast beacon (Beacon) frame, comprise the information of access point in the beacon frame, such as basic service set identification (BSSID, Basic Service Set Identity), and the various ability information supported of access point etc.User terminal can the listen for beacons frame to find existing of access point.

Active scan: user terminal initiatively sends probe requests thereby (Probe Request) message and finds the existence of access point, such as, specifically can send probe request message through broadcasting or clean culture.If probe request message is broadcasted, the access point that then receives probe request message can return probe response message and give relevant user terminals.If probe request message is clean culture, user terminal in probe request message clear and definite appointment the BSSID of access point, then have only this appointed access point after receiving probe request message, just can return probe response message.The BSSID of this access point and various ability information that this access point is supported etc. have been comprised in the probe response message.In addition, access point can also carry the needed out of Memory of user terminal according to the indication of user terminal in probe request message in probe response message.

User terminal can use various battery saving modes in order to save electric energy, and for example, user terminal can be appointed dormancy period, recovery time point etc. with access point, so that access point transmits data at the time point of agreement to user terminal.User terminal can send data at any time in the competition phase of access point arrangement, prerequisite is that contention arrives channel.In the poll phase, user terminal can not initiatively send data, and when having only access point to inquire user terminal, user terminal just can send data.

On the basis of the above, the embodiment of the invention provides a kind of method and access point of managing access point working group.

In embodiments of the present invention; Comprise a main access point and at least one secondary access point in the access point working group, wherein, which access point is main access point; Which access point is secondary access point, can or local preset or decides by holding consultation between the access point access point through network.Wherein, main access point is in normal service state (Serving State) all the time, and secondary access point can be in service state and holding state (Standby State).Service state is meant that user terminal can find this access point, can be connected to this access point and use this access point to communicate.Holding state then refers to user terminal can not find this access point, does not also have the user terminal that has connected on this access point, that is to say that from the angle of user terminal, this access point has shut down.Secondary access point can also be in a kind of transition state (Transiting State), and expression is stopping service, no longer accepts new user terminal, but the user terminal of having linked this access point can continue to use.

Wherein, need communicate between main access point and the secondary access point, when main access point and secondary access point communicated, secondary access point used the wireless channel of main access point to communicate as the user terminal role of main access point; And do not communicate between secondary access point and the secondary access point.Secondary access point can send load information and/or state information to main access point, and under the control of main access point, gets into holding state or service state.Below with being elaborated respectively.

Embodiment one,

Present embodiment will be described from the angle of main access point.

A kind of method of managing access point working group; Comprise: main access point receives load information and/or the state information that secondary access point reports in the working group of current access point; According to said load information and/or state information the state of secondary access point is controlled; Wherein, main access point and secondary access point are preset by network or decide by holding consultation between the access point.

In addition, before main access point receives the load information and/or state information that secondary access point reports in the working group of current access point, also need connect between main access point and the secondary access point, promptly the method for this management access point working group can also comprise:

It is related that main access point and secondary access point in the working group of current access point carry out, and negotiation communication mechanism.

If consulted communication mechanism between main access point and the secondary access point; Communicating by letter between then main access point and the secondary access point need be followed the communication mechanism of this negotiation; I.e. this moment, main access point receive secondary access point reports in the working group of current access point load information and/or state information specifically can for:

Main access point receives load information and/or the state information that secondary access point reports in the working group of current access point according to the communication mechanism of consulting.

According to the load information that receives and/or state information to the state of secondary access point control then specifically can for:

According to the communication mechanism of consulting, the state of said secondary access point is controlled according to load information and/or state information.

As shown in Figure 1, idiographic flow can be following:

101, the secondary access point negotiation communication mechanism of at least one in the main access point in the access point working group and this access point working group;

Wherein, main access point and secondary access point can be preset by network in advance, and promptly specifying which access point in advance is main access point; Which access point is secondary access point, such as, can in main access point, it be set to " main access point "; And the sign of disposing secondary access point, and it is set to " secondary access point " in secondary access point, and the sign of main access point is set; The process of this setting can be provided with through webmaster, also can be provided with through manual.

Perhaps, main access point and secondary access point also can be decided by holding consultation voluntarily between the access point.Such as, specifically can be following:

Access point sends probe request message to seek main access point, if can find main access point, confirms that then this access point is secondary access point;

If do not find main access point, and do not find other access points, confirm that then this access point is main access point with access point working group;

If do not find main access point, but find other access points, then with other access points of access point working group consult to confirm main access point with access point working group.Wherein, this negotiation can be main access point such as the access point that can arrange to start shooting the earliest based on a strategy that presets; Perhaps, also can arrange the minimum access point of MAC Address as main access point, or the like; This presets strategy can decide according to the practical application needs, repeats no more at this.

After the major-minor access point is divided; When each access point start, secondary access point can be found main access point through the mode of drive sweep, such as the beacon frame of intercepting main access point; If can hear, explain that then the main access point in this access point working group is confirmed.In addition; Secondary access point can also be found main access point through the mode of active scan; The mode of the mode of this active scan and user terminal active scan access point is similar; Promptly this moment, secondary access point can be used as a user terminal, sought main access point through sending probe request message, if having main access point in the access point working group under should the pair access point; Then main access point can return probe response message and give corresponding secondary access point, thereby makes the existence of secondary access point discovery master access point.That is to say that before the secondary access point negotiation communication mechanism in main access point and current access point working group, the method for this management access point working group can also comprise:

Receive the probe request message that secondary access point sends in the working group of current access point, return probe response message and give secondary access point.

Wherein, can indicate this access point in the probe request message is secondary access point, and can carry the sign of the main access point that needs searching, such as the BSSID of main access point; After the pairing main access point of the sign of this main access point receives this probe request message, return probe response message and give this pair access point.

Perhaps, can indicate this access point in the probe request message is secondary access point, but does not carry the sign of the main access point that needs searching; But the sign of carrying this access point, such as the BSSID of this access point, owing to dispose the sign of secondary access point in this access point working group in the main access point; So,, just can confirm whether this pair access point is the secondary access point of this access point working group according to the sign of the entrained secondary access point of the probe request message that receives; If; Then return probe response message and give this pair access point, otherwise, the response that responds or return refusal do not returned.

Certainly, can also carry other information in probe request message and the probe response message, repeat no more at this.

Wherein, The content of the communication mechanism of consulting between main access point and the secondary access point specifically can be decided according to the demand of practical application; Such as; Can comprise call duration time section and commitment defini interval cycle etc.; And can comprise call duration time section communication and the gap periods of secondary access point to main access point transmission load information and/or state information particularly, and main access point is to time period and the gap periods or the trigger mechanism etc. of secondary access point transmit status control information (i.e. the back said first State Control information of literary composition or the second State Control information); For example; Trigger mechanism can be given main access point for: secondary access point and send any message M; Main access point is after receiving this any message M; Send out State Control information for secondary access point,, then can not give the control information of secondary access point transmit status if main access point does not receive the message of secondary access point.Certainly, also can trigger conversely, such as, could send out load information to main access point after having only secondary access point to receive the message of main access point, or the like.Repeat no more at this.

102, main access point receives load information and/or the state information that the secondary access point in this access point working group sends according to the communication mechanism of consulting to confirm the back.

What need explanation is because when secondary access point is in holding state, its load is 0 always, so this moment also not load information reporting to main access point.

103, main access point sends message or instruction according to the load information that receives and/or state information according to the communication mechanism of consulting to confirm the back at least one secondary access point in said access point working group at least, so that receive the secondary access point switching state of said message or instruction.

For example, specifically can be following:

The total load rate that load information that main access point basis receives or state information are confirmed current access point working group;

The state that load information that main access point basis receives or state information are confirmed the secondary access point in this access point working group;

If the total load rate surpasses first preset threshold value; Then main access point sends message or instruction according to the communication mechanism of consulting to confirm the back to the secondary access point that at least one is in holding state, switches to service state so that receive the secondary access point of this message or instruction from holding state.

Perhaps,

If the total load rate low second preset threshold value, then main access point sends message or instruction switches to holding state so that receive the secondary access point of said message or instruction from service state according to the communication mechanism of consulting to confirm the back at least one secondary access point that is in service state.

Wherein, first preset threshold value and second preset threshold value can be decided according to the demand of practical application, and first preset threshold value is more than or equal to second preset threshold value.

If the total load rate does not surpass first preset threshold value, but is higher than second preset threshold value, then can keep current states, promptly main access point does not indicate secondary access point to carry out the state switching.

Wherein, The total load rate is meant the percentage of the bandwidth resources occupied (just having distributed to the bandwidth resources that user terminal uses) that the access point of current service state can provide; For example, main access point can provide the bandwidth of 300Mbps, and other has a secondary access point that the bandwidth of 200Mbps can be provided; Then the access point in two services can provide the bandwidth resources of 500Mbps altogether; And the existing 150Mbps bandwidth resources of current main AP are assigned with, and secondary AP also has the 150Mbps bandwidth resources to distribute, and then system's total load rate is: (150+150)/(300+200)=60%.

If main access point thinks that 60% total load rate has surpassed first preset threshold value, then can notify another secondary access point to get into service state.If these second available bandwidth resources of secondary access point is 300Mbps, then current total load rate becomes after it gets into service state: (150+150)/(300+200+300)=37.5%.

If main access point thinks that 37.5% total load rate has still surpassed first preset threshold value, then can also reinform another secondary access point and get into service state, the rest may be inferred, till the total load rate is lower than first preset threshold value.

What need explanation is; Secondary access point can directly be to have distributed bandwidth resources to the load information that main access point sends; Also can be the load factor of this pair access point oneself, main access point can be calculated the bandwidth resources of having distributed with load factor according to the provided bandwidth resources of secondary access point.

Before secondary access point gets into holding state; If current had user terminal to be linked on this pair access point; Then secondary access point can be moved in main access point or the current access point working group other with the user and is on the secondary access point of service state; By the time when not having user's (promptly not having load) on this secondary access point, just get into holding state.That is to say that at this moment, for main access point, after the secondary access point that is in service state according to state information notification got into holding state, the method for management access point working group can also comprise:

Main access point is accepted the user that moves out from the secondary access point that is about to get into holding state.

By on can know; Present embodiment adopts the access point in the access point working group is divided into main access point and secondary access point, can negotiation communication mechanism between main access point and the secondary access point, and main then access point receives load information and/or the state information that secondary access point reports according to consulting the definite communication mechanism in back; And according to consulting the communication mechanism that the back is confirmed; According to load information that receives and/or state information the state of secondary access point is controlled, thereby achieved a butt joint into the flexible management of a working group, such as; During the total load in access point working group heavier (bigger) such as the total load rate; Control secondary access point by main access point and get into service state, satisfying the demand of user terminal, and in the total load of access point working group when light (less such as the total load rate); Control secondary access point by main access point and get into holding state, to save electric energy.

Embodiment two,

Present embodiment will be described from the angle of secondary access point.

A kind of method of managing access point working group comprises: secondary access point load information reporting and/or state information are given main access point in the working group of current access point, accept the State Control that main access point is made according to said load information and/or state information.Wherein, main access point and secondary access point are preset by network or decide by holding consultation between the access point.

In addition, give in the working group of current access point before the main access point in secondary access point load information reporting and/or state information, also need connect between secondary access point and the main access point, promptly the method for this management access point working group can also comprise:

It is related that secondary access point and main access point in the working group of current access point carry out, and negotiation communication is machine-processed; Wherein, the content of the communication mechanism of this negotiation specifically can be decided according to the demand of practical application, such as, can comprise call duration time section and commitment defini interval cycle etc., referring to embodiment one, repeat no more at this.

If consulted communication mechanism between secondary access point and the main access point; Communicating by letter between then secondary access point and the main access point need be followed the communication mechanism of this negotiation; I.e. this moment, secondary access point load information reporting and/or state information give in the working group of current access point main access point specifically can for:

Secondary access point is given main access point in the working group of current access point according to communication mechanism load information reporting of consulting and/or state information.

Accept State Control that main access point makes according to load information and/or state information then specifically can for:

Accept main access point according to the communication mechanism of consulting, the State Control of making according to load information and/or state information.

As shown in Figure 2, idiographic flow can be following:

201, the main access point negotiation communication mechanism in secondary access point in the access point working group and the said access point working group;

Wherein, after the major-minor access point is divided, when each access point start; Secondary access point can be found main access point through the mode of drive sweep; Such as the beacon frame of intercepting main access point,, explain that then the main access point in this access point working group is confirmed if can hear.In addition; Can also find main access point through the mode of active scan; The mode of the mode of this active scan and user terminal active scan access point is similar; Promptly this moment, secondary access point can be used as a user terminal, sought main access point through sending probe request message, if having main access point in the access point working group under should the pair access point; Then main access point can return probe response message and give corresponding secondary access point, thereby makes the existence of secondary access point discovery master access point.That is to say that carry out relatedly at secondary access point and main access point in the working group of current access point, and before the negotiation communication mechanism, the method for this management access point working group can also comprise:

Send probe request message, receive the probe response message that main access point returns in the working group of current access point.

202, secondary access point sends load information and/or state information according to the communication mechanism of consulting to confirm the back to main access point;

What need explanation is because when secondary access point is in holding state, load is 0, so this moment also not load information reporting to main access point.

203, secondary access point receives message or the instruction that said main access point sends according to the load information that receives and/or state information at least.

204, secondary access point is according to message that receives or instruction switching state.Such as, secondary access point switches to service state according to the message or the instruction that receive with current holding state; Perhaps, secondary access point switches to holding state according to the message or the instruction that receive with current service state.

For example, specifically can be following:

When receiving the first State Control information of main access point transmission, current holding state is switched to service state;

When receiving the second State Control information of main access point transmission, current service state is switched to holding state.

Wherein, the first State Control information and the second State Control information are made according to load information and/or state information by main access point, specifically can be referring to embodiment one.

Before secondary access point gets into holding state; If current had user terminal to be linked on this pair access point; Then secondary access point can be moved in main access point or the current access point working group other with the user and is on the secondary access point of service state; By the time when not having user's (promptly not having load) on this secondary access point, just get into holding state.Promptly before current service state was switched to holding state, the method for this management access point working group can also comprise:

Secondary access point determines whether to exist the user to insert, if confirm as is, the user who inserts is moved in main access point or this access point working group other be in the secondary access point of service state.

Then this moment, current service state is switched to holding state be specially: when this secondary access point does not have load, current service state is switched to holding state.

By on can know that present embodiment adopts the access point in the access point working group is divided into main access point and secondary access point, can negotiation communication between secondary access point and the main access point machine-processed; Secondary then access point is given main access point according to communication mechanism load information reporting of consulting to confirm the back and/or state information; And accept the State Control that main access point is made according to the load information that receives and/or state information, thus achieve a butt joint into the flexible management of a working group, such as; When the total load of access point working group is heavier; Control secondary access point by main access point and get into service state, satisfying the demand of user terminal, and when the total load of access point working group is light; Control secondary access point by main access point and get into holding state, to save electric energy.

Embodiment three,

According to the described method of front embodiment, below will do further explain for example.

In the present embodiment, will be that example describes to set main access point and secondary access point through preset mode.

Since preestablished cover the same area access point who as main access point who as secondary access point, so main access point is after start; Can directly get into service state; And after the secondary access point start, need at first to find main access point as the user terminal role, carry out related with main access point then; And negotiation communication mechanism (if communication after promptly consulting), get into holding state afterwards.When main access point confirms that this regional total load is overweight, just notify secondary access point to get into service state; When main access point discovery confirms that this regional total load is light, can notify secondary access point to get into holding state again, the rest may be inferred.Wherein, Secondary access point needs periodicity load information reporting and/or state information to give main access point; So that main access point can be confirmed the total load situation that this is regional according to load information and/or state information, and confirm secondary access point current states (promptly being service state or holding state).

Below will be described in detail this scheme, referring to Fig. 3, specifically can be following:

301, confirm main access point and secondary access point in the access point working group through configuration, wherein, comprise a main access point and at least one chromaffin body point in the access point working group, for example, specifically can be following:

In main access point, its attribute is confirmed as " main access point ", and the sign of the secondary access point in this access point working group is set in main access point, such as the BSSID of secondary access point.

In each secondary access point, its attribute is confirmed as " secondary access point ", and the sign of main access point is set on secondary access point, such as the BSSID of main access point.

During practical implementation, can be provided with, also can be provided with, repeat no more at this through manual mode through webmaster.

302, each access point (comprising main access point and secondary access point) start.Main access point start back directly gets into service state, is subscriber terminal service.And do not get into service state after the secondary access point start, but get into holding state, and seek main access point as user terminal, for example, specifically can be following:

It is basic identical that secondary access point is sought the process of main access point and general user terminal scanning access point; Different is; Secondary access point is when sending probe request message; Except can carrying self sign (being source address) of (being secondary access point), can also in probe request message, indicate this access point is a secondary access point, and can directly indicate the sign (being destination address) of the main access point that will find.

Because the sign of secondary access point has been configured on the main access point, so main access point after receiving probe request message, can judge whether this pair access point is the secondary access point of this access point working group according to the sign (being source address) of the secondary access point that carries in the probe request message; If then main access point returns probe response message to the chromaffin body point, otherwise; If not; The response message of then being failure to actuate or returning refusal is to the chromaffin body point, and wherein, it oneself is main access point that main access point can indicate in probe response message; And the sign that can carry main access point, can also carry needed other information of secondary access point.

When secondary access point received the probe response message that host node returns, main access point had been found in expression.

303, after the secondary access point discovery master access point, with main access point in the working group of current access point carry out related, and with main access point negotiation communication mechanism, such as agreement call duration time point, commitment defini interval cycle etc.

Wherein, association process is identical, optional with association process between existing user terminal and the access point, secondary access point can also and main access point between carry out authentication each other.In addition; The communication mechanism of being consulted between secondary access point and the main access point can adopt the automatic power save transmission mechanism (S-APSD of the reservation that defines in the existing standard; Scheduled Automatic Power-Save Delivery) similarly machine-processed, repeat no more at this.

304, after the operation in execution of step 303, secondary access point gets into holding state, and do not send beacon frame (Beacon) this moment, do not respond the probe request message (Probe Request) of user terminal yet.

Secondary access point is under holding state; According to and main access point between the communication mechanism consulted periodically to main access point send state information and/or load information; Such as; Can basis and the call duration time point of main access point agreement, and call duration time is at interval to main access point send state information and/or load information.

Certainly, when being in holding state, there is not load owing to secondary access point; So also can not send load information and give main access point this moment; But only send state information is given main access point, and, in state information, can indicate secondary access point to be in holding state.

What need explanation is that no matter which kind of state secondary access point is in, and needs only to have powered on start and be associated with main access point, then need periodically carry out alternately with main access point according to the communication mechanism of consulting, to show that it is at net.Wherein, this also can adopt the empty Frame in the existing standard to realize alternately, and need not define new signaling frame.In addition, for more power saving, the access point of holding state can be established longlyer to the cycle of main access point send state information; But still with the control messages that possibly send than the short main access point of cycle wait reception; Like this, the secondary access point that just can as far as possible reduce holding state sends the number of times of message, feasible more power saving; But can become service state from holding state in time when needed, to satisfy the demand of network.These mechanism can be held consultation in the stage of secondary access point and main access point negotiation communication mechanism, can certainly consult on the opportunity that secondary access point state changes again, and repeated no more here.

Communication between secondary access point and the main access point can be adopted independently control channel, also can adopt the channel of main access point.General, channel that all can main access point, because if so, the control of the channel of main access point is just fairly simple, is getting final product aspect the channel control secondary access point being handled as an application terminal.

305, main access point receives load information and/or the state information that secondary access point reports, and confirms the total load of current access point working group according to load information, calculates the total load rate; If the total load rate surpasses first preset threshold value; Then execution in step 306, otherwise, be failure to actuate.If the total load rate low second preset threshold value, then execution in step 309, otherwise, be failure to actuate.

Wherein, the method for calculating the total load rate can repeat no more at this referring to embodiment one.

306, main access point gets into service state according to the state information first State Control information of sending with the secondary access point that notice is in holding state according to the communication mechanism of consulting.

For example, main access point can according to the communication mechanism of consulting, be given secondary access point such as the call duration time point first State Control information of sending through the channel of self, switches to service state to notify it from holding state.Wherein, main access point can according to the state information that secondary access point reported confirm which secondary access point current be to be in holding state.

307, after secondary access point receives the first State Control information, get into service state, periodically send beacon frame (Beacon), also respond the probe request message of user terminal, accept the association request of user terminal etc., specifically can be referring to prior art.

What need explanation is that secondary access point the time that the palpus reservation is communicated by letter with main access point, promptly can not be subscriber terminal service with the call duration time section that main access point is arranged, to avoid producing conflict in the channel control procedure.About this point, can realize through the non-competing phase that will be arranged in channel control with the time period that main access point is communicated by letter.In the non-competing phase; Who can use channel, when puts use, use and how long controlled by access point; As long as secondary access point is at the time period of communicating by letter with main access point poll user terminal or arrange the period of service to user terminal not; Interior during this period of time user terminal can not use channel naturally, thereby can not produce conflict.In addition; Secondary access point also can be arranged access point rest period in addition; To be included in this access point with the time period that main access point is communicated by letter in rest period; And in the probe request message of some signaling message like beacon frame and the clean culture of broadcasting, indicate and informing user terminal, user terminal is just known interior during this period of time can not communication with this access point like this.

308, secondary access point need send to main access point such as call duration time gap periods property with load information according to the communication mechanism of consulting under service state, simultaneously, can also send state information give main access point, is in service state to indicate it.

Main access point receives load information and/or the state information that secondary access point reports, and confirms the total load of current access point working group according to load information, calculates the total load rate, and promptly execution in step 305.

309, main access point gets into holding state according to the state information second State Control information of sending with the secondary access point that notice is in service state according to the communication mechanism of consulting.

For example, main access point can according to the communication mechanism of consulting, be given secondary access point such as the call duration time point second State Control information of sending through the channel of self, switches to holding state to notify it from service state.Wherein, can indicate the sign of the secondary access point of purpose in the second State Control information.Wherein, main access point can according to the state information that secondary access point reported confirm which secondary access point current be to be in holding state.

The secondary access point that 310, will get into holding state can be transferred on other secondary access points that are in service state having the user terminal that is connected on this secondary access point now, also can be with having load transfer now to main access point.When on the secondary access point do not have load the time, just can get into holding state.Wherein, these other secondary access point can be specified by main access point.

For convenience, in embodiments of the present invention, secondary access point is called transition state transit time from this section that service state gets into holding state.That is, secondary access point at first gets into transition state after receiving the second State Control information, when treating not have load on this secondary access point, just can get into holding state.

What need explanation is, the process at migrated users terminal can be carried out according to the process that defines in the 802.11v standard, if user terminal is not supported the migration operation of 802.11v, then secondary access point should wait for that user terminal moves back net.In addition, under transition state, secondary access point can continue to send beacon frame, and can in beacon frame, indicate and no longer receive new user.And; Secondary access point does not respond the probe request message of user terminal; If user terminal sends probe request message to this access point specially with mode of unicast, then secondary access point can not respond, or new user terminal is not accepted in indication at present in probe response message.Under transition state, secondary access point also need send load information to main access point, and can indicate it in an interim state.

When the secondary access point under in an interim state does not have load, just get into holding state, the secondary access point that gets into holding state stops to send beacon frame, also can not respond the probe request message of user terminal.Because secondary access point under holding state, only is in the active state (Active State) of 802.11 definition when communicating by letter with main access point, be in resting state (Idle State) At All Other Times, therefore, can reach the purpose of saving electric energy.In addition, optional, under loaded situation, for example under the transition state, secondary access point can also not need with dormancy in time period of user terminal communication, to reach the power saving purpose.

By on can know, present embodiment adopt the mode preset just the access point in the access point working group be divided into main access point and secondary access point, wherein; Secondary access point can load information reporting and/or state information give main access point, the state of chromaffin body point is controlled according to the loading condition of network by main access point then, feasible when total load is heavier; Secondary access point can get into service state; Satisfying the demand of user terminal, and when total load was light, secondary access point can switch to holding state; Reaching the purpose of saving electric energy, thereby achieve a butt joint into the flexible management of a working group.

Embodiment four,

Present embodiment is similar with the scheme that enforcement three is provided; Different is in embodiment three, mainly to adopt preset mode to set main access point and secondary access point; And in the present embodiment, will be that example describes to set main access point and secondary access point through the negotiation between the access point.

At first, need be through disposing the access point that confirm to be in the same access point working group (being called for short on the same group), such as, can the access point that be in the same access point working group be set to identical group number an assembly.But different with embodiment three is that present embodiment does not confirm through configuration which access point is as main access point; Which access point is as secondary access point; And need not on access point, not dispose the sign of other access point on the same group, certainly, also can on access point, dispose the sign of other access point on the same group; Like this, follow-up each access point just can carry out simple authentication through the access point identity of configuration when access point is found mutually on the same group.Wherein, above-mentioned layoutprocedure can be carried out through webmaster, also can carry out through manual mode, repeats no more at this.

After configuration finishes, each access point start in the access point working group, and hold consultation to confirm main access point.For example, specifically can adopt following method to confirm main access point:

At first as the user terminal role, seek main access point after the access point start.The mode of user terminal scanning access point is similar in concrete mode and the prior art; Such as; Access point can be intercepted the beacon frame of main access point or sent the probe request message of broadcasting and find main access point on the same group, if can hear the beacon frame of main access point on the same group, perhaps receives the probe response message of main access point; The main access point that this group then is described is definite, can confirm that then this access point is secondary access point.Wherein, can indicate the access point that sends this probe response message in the probe response message of main access point is main access point.

If can not listen to the beacon frame of main access point or receive the probe response message of main access point, then, can respond the probe request message of other access point, but not send beacon frame as the access point operation.After the probe response message that receives other access point of this group, whom consults with it as main frame, for example, can be with available machine time or MAC Address as the judgement foundation, such as start the earliest as main frame, or MAC Address minimum as main frame, or the like.

In order to realize the negotiations process of main access point, access point need carry the sign that can confirm access point working group in probe request message, such as the AP group number, so that each access point can be found out other access points on the same group.In addition, if with the available machine time as the foundation of confirming main access point, then can also in probe request message, carry elapsed time since the access point start, this time can be unit with delicate or ticktock number specifically.If, then can not need to carry in addition MAC Address, because the MAC Address of access point just was included in the probe request message as the source address of transmission probe request message originally with the foundation of MAC Address as the main access point of affirmation.

If can not find main access point, can not find other access point on the same group, then this access point oneself is started working as main access point.

After confirming main access point, main access point can indicate that it is main access point in the beacon frame of its transmission, perhaps, in it returns to the probe response message of other access points, indicates that it is main access point.

What need explanation is, the process of confirming main access point also can be confirmed network promoter's process with reference to network in the independent basic service set in 802.11 standards (IBSS, Independent Basic Service Set), repeats no more at this.

After confirming main access point, follow-up flow process is identical with embodiment three, specifically can repeat no more at this referring to embodiment three.

In addition, what also need explain is, in the scheme that present embodiment provided; If main access point fault, no matter then secondary access point is at service state or holding state, will find to communicate with main access point; So, at this moment, each secondary access point needs to consult mutually to produce new main access point; Concrete machinery of consultation can be referring to the process of the main access point of above-mentioned negotiation, certainly, and in order to save signaling process; In the specific implementation, also can carry out, but directly the secondary access point that present load is the heaviest upgrades to main access point not according to the process of the main access point of above-mentioned negotiation.
