The embodiment of the present invention provides a kind of method of WAP and terminal communication, is mainly used in such as Fig. 1 In the wireless network of shown Radio Network System, such as WiFi network or macro base station, this system includes nothing Line access point and multiple terminal (STA), include again multiple radio access management module in WAP, Each radio access management module is the different terminals clothes in same physical wireless access point coverage Business, in such as Fig. 1, radio access management module 1 is that terminal 11 services to terminal 1o, and radio access management Module 2 is that terminal 21 arrives terminal 2p service etc., and these terminals are all to cover at a physical wireless access point In the range of terminal.

The real resource of this WAP can be carried out heavily by WAP by certain computational methods Distribution, fictionalizes multiple radio access management modules that function is identical, for each radio access management mould After block distribution resource, each radio access management module will be corresponding terminal service, and is independent of each other. When WAP distribution resource, mainly distribute each radio access management module and the end serviced The wireless access point identification used when communicating between end such as basic service set identification (Basic Service Set Identifier, BSSID) etc. can uniquely identify the information of each radio access management module (being the wireless access point identification that the beacon frame distribution of transmission is corresponding), and use each WAP mark Knowing the parameter information sent needed for beacon (hereinafter referred to as Beacon) frame, such as Beacon frame sends week Phase, the pot life section within the Beacon frame transmission cycle and/or unavailable time section, transmission Beacon frame Transmit power, competition phase (competition period, CP) in pot life section and exempt from the competition phase Parameters such as (competition free period, CFP), and to store WAP be each wireless access The wireless access point identification of management module assignment and the parameter using this wireless access point identification to send beacon frame The corresponding relation of information.Wherein:

In pot life section within the Beacon frame transmission cycle may refer in this pot life section, terminal Specific wireless channel can be used to enter with the radio access management module that this wireless access point identification is identified Row communication, can be specifically that start transmission comprises the first access point identity to a radio access management module certainly Beacon frame start transmission to adjacent next radio access management module and comprise the second access point identity The time interval of Beacon frame, and unavailable time section refers within the Beacon frame transmission cycle except available Time outside time period is unavailable time section；And meeting between terminal within the competition phase of pot life section The use chance of wireless channel is obtained by competition mechanism, and will be by radio access management in exempting from the competition phase Module is the use chance of the terminal coordination distribution channel of service.

Specifically, WAP, when for radio access management module assignment resource, can be each nothing Line Access Management one corresponding wireless access point identification of distribution, specifically, can be according to preset Rule obtains, such as based on WAP medium access control (MediaAccess Control, MAC) Address identifies, and is calculated multiple wireless access point identifications etc., the most preset rule by certain Can be to be preset in WAP according to different needs；And WAP can distribute each nothing Line Access Management uses identical or different power to send Beacon frame by physical layer.

WAP after the distribution completing resource, WAP just can by the following method with end End carries out data transmission: i.e. within each beacon frame information cycle, and multiple wireless in WAP connects Entering to manage module uses different wireless access point identification orders to send different beacon frames, at beacon respectively Frame carries a wireless access point identification of correspondence, and for indicating the instruction information of pot life section； The terminal so receiving beacon frame can be in the pot life section indicated by instruction information, according to correspondence Wireless access point identification and WAP are carried out into net operation.Wherein, in each beacon frame information cycle In, different wireless access point identifications can be used the most respectively to send different beacon frames, Beacon frame can also be sent according to random order.

Such as shown in Fig. 2, it is assumed that a WAP includes 3 radio access management modules 1,2 and 3, Within each beacon frame information cycle, radio access management module 1,2 and 3 can be distinguished in the following order Send different beacon frames: radio access management module 1 uses wireless access point identification 1 to send Beacon frame 1 Rear a period of time, radio access management module 2 uses wireless access point identification 2 to send latter one section of Beacon frame 2 Time, radio access management module 3 uses wireless access point identification 3 to send Beacon frame 3.Implement at other In example, it is possible to use random order sends Beacon frame 1,2 and 3.

Wherein for radio access management module 1, the Beacon frame transmission cycle refers to from wireless access pipe Reason module 1 sends Beacon frame 1 and starts to radio access management module 1 to send between Beacon frame 1 next time A time period；Pot life section refers within the Beacon frame transmission cycle, from radio access management mould Block 1 starts to send between the time that Beacon frame 1 starts to send Beacon frame 2 to radio access management module 2 Every, unavailable time section refers to that the time within the Beacon frame transmission cycle in addition to pot life section is not Pot life section.

Specifically, for each radio access management module, can perform according to the steps, Flow chart is as it is shown on figure 3, include:

Step 101, radio access management module is by a corresponding wireless access point identification, and is used for indicating Within the Beacon frame transmission cycle, the instruction information of pot life section is added in Beacon frame.

It is appreciated that radio access management module can periodically send Beacon frame, is specifically sending Before Beacon frame, need to add the wireless access point identification of instruction information and this radio access management module In Beacon frame, instruction information can be the information directly indicating pot life section here；Or use Beacon frame sends the information of cycle and unavailable time section and indirectly indicates pot life section, in this feelings Under condition, the pot life section of instruction be Beacon frame send the cycle deduct unavailable time section.

Here, the pot life section in the Beacon frame transmission cycle may refer to this radio access management module Start to send Beacon frame to adjacent next radio access management module from starting to send Beacon frame Time interval.

Step 102, radio access management module uses corresponding wireless access point identification to send according to step 101 be added after Beacon frame.

Then in the present embodiment, each radio access management module can use respective wireless access point identification Transmission Beacon frame, to terminal, after terminal receives this Beacon frame, will indicate in Beacon frame Pot life section indicated by information, according to the wireless access point identification carried in beacon frame and wireless access What point carried out terminal enters net operation.

In the present embodiment, each radio access management module can send different Beacon frames to wireless access Terminals different in some coverage, and within a beacon frame information cycle, each radio access management The i.e. wireless access point identification of mark that module carries out using when Beacon frame sends is different, and each nothing The time point that line Access Management sends Beacon frame is different.And each radio access management module Identical or different power can be used to send Beacon frame, i.e. each radio access management module uses Corresponding wireless access point identification send transmit power used during different beacon frames can identical can also Different.

Visible, in the WAP of the present embodiment with the method for terminal communication, a physical radio connects Access point can include multiple radio access management module, and these multiple radio access management modules can use respectively Different wireless access point identification orders sends different beacon frames, carry correspondence within a beacon frame one Wireless access point identification, and for indicating the instruction information of pot life section, in order to terminal is in instruction information In indicated pot life section, carry out according between corresponding wireless access point identification and WAP Terminal enter net operation.Such a physical wireless access point can be taken by multiple wireless access point identifications It is engaged in different terminals, only comprises one owing to a beacon frame comprising in a TIM, and a beacon frame Wireless access point identification, so wireless access point identification can correspond to the association determined by TIM figure place Identifier space.For terminal, each access point identity is equivalent to an access of the prior art Point.Thus, embodiments of the invention expand the terminal quantity that a physical wireless access point is supported, The number of terminals that the terminal quantity that one WAP is supported is actual in can reaching its coverage Amount, without at the multiple physical wireless access point of same regional deployment, thus reduces wireless access The waste of some resource, improves the utilization rate of a WAP.

In a specific embodiment, each radio access management module perform above-mentioned steps 102 it Before, it is also possible to the out of Memory that WAP is distributed to this radio access management module adds to In Beacon frame, such as by the competition phase in pot life section and/or exempt from the information such as competition phase and add to In Beacon frame, such terminal will the competition phase or in exempting from the competition phase with the competition phase or to exempt from the competition phase corresponding Communication mode (such as competitive way or non-competing mode) communicate with WAP.Specifically, Channel use chance of vying each other is needed between multiple terminals within the competition phase；And in exempting from the competition phase terminal Between need not competition, by the use to channel of the terminal of the multiple service of radio access management module coordination.

It should be noted that after WAP sends beacon frame by radio access management module, if There is terminal to receive this beacon frame, then carry out into net operation, specifically between this terminal meeting and WAP Ground, terminal can send the request message that networks to wireless access according to the wireless access point identification in beacon frame Point, then WAP can come to carry out into net operation with terminal in accordance with the following steps, flow chart such as Fig. 4 institute Show, including:

A, the respective wireless Access Management in WAP receives the networking request message that terminal sends After, if being directly accepted as this terminal service, then this radio access management module performs step B；If no Be accepted as this terminal service, then this radio access management module performs step C.

Be appreciated that after WAP powers on, including multiple radio access management modules i.e. Can the most periodically send Beacon frame, after the terminal not networked receives Beacon frame, with Carry out between corresponding radio access management module detecting, system authentication and association etc. enter net operation.

B, radio access management module use network request wireless access point identification corresponding to message with ask into The terminal of net is carried out into net operation, can return networking response message to this terminal, and instruction is accepted as this end End service.

C, radio access management module determine wireless access point identification corresponding to this radio access management module it Other outer wireless access point identification, and perform step D, specifically when determining other wireless access point identification, Can be determined by following several ways:

(1) wireless access point identification is used according to multiple radio access management modules in WAP respectively Terminal quantity and first presetting rule of corresponding service determine other wireless access point identification.

Here the first presetting rule may include that the terminal quantity of corresponding with service less than a preset value The wireless access point identification of radio access management module be defined as other wireless access point identification etc., So that the wireless access point identification loading less radio access management module is defined as other WAP Mark so that the load (terminal quantity i.e. serviced) of each radio access management module controls one In the range of Ding.

(2) in acquisition WAP, the use of radio access management module networks, and request message correspondence is wireless to be connect Entering point identification, power demand information during the terminal called networked with request, and according to this power demand information And second presetting rule determine other wireless access point identification in networking response message.

Be appreciated that if each radio access management module send Beacon frame time use transmission merit Rate is different, then when not entering during network termination carries out net operation, when radio access management module exists After receiving networking request message, can detect and this does not enters to carry out between network termination power demand letter during communication Breath, if with send Beacon frame power not to time corresponding so that the laser propagation effect of data is higher or Making the more power saving of WAP and terminal, this radio access management module can select to send other nothing Line access point identity, the second presetting rule can be to select, in multiple radio access management modules, to send out here Send the radio access management module that the power of Beacon frame is corresponding with the power demand of this detection, and will choosing The wireless access point identification of the radio access management module selected is as other wireless access point identification, Ji Jiangfa When sending the power of beacon frame corresponding with the power demand of detection, send the wireless access that beacon frame is used Point identification is defined as other wireless access point identification.Wherein, the power of described transmission Beacon frame with should The power demand of detection is corresponding to be referred to, Beacon frame power is closest and the least with the power demand of detection In power demand.

Specifically, radio access management module, can be to end when the communication power detected between terminal End sends transmitting power control (transmit power control, TPC) request, and receives terminal return TPC response.

D, radio access management module uses the wireless access point identification that the request message that networks is corresponding, to request The terminal networked returns networking response message, carries other wireless access point identification in networking response message, So terminal can carry out into net operation according to other wireless access point identification and WAP, and concrete enters Carry out between net operation with this radio access management module and terminal to enter net operation similar, do not carry out at this Repeat.And the pot life that other wireless access point identification is corresponding can also be carried in networking response message The instruction information of section, such terminal is networking with WAP according to other wireless access point identification During operation, the pot life section indicated by instruction information can carried in networking response message is with wireless Access point is carried out into net operation.

Above-mentioned networking request message can be association request (Association Request), certification request or Detection (Probe) requests etc., then networking response message is correspondingly associated response, authentication response or detection Response etc..

It should be noted that the method in the embodiment of the present invention can apply to WAP use difference In the scene of power service zones of different STA, wherein for supporting and WAP maximum communication power phase Corresponding STA, can arbitrarily select a region when disposing in the signal cover of WAP Dispose；But for the STA that maximum transmission power is the most corresponding with WAP maximum transmission power, then The transmission range corresponding to maximum transmission power can supported according to STA when disposing, at wireless access The region of deployment is determined for STA, such as: maximum transmission power is bigger in the signal cover of point STA is deployed in distance WAP region farther out, is deployed in by STA less for maximum transmission power In the region that distance WAP is nearer etc..By the program, so that a WAP is same Time be that the STA supporting multiple different transmission power services.
