技术领域 FIELD

[0001] 本发明涉及无线网络技术,特别涉及一种无线客户端接入的控制方法和无线接入系统。 [0001] The present invention relates to a wireless network technology, particularly to a method of controlling a wireless client terminal and a wireless access system access.

背景技术 Background technique

[0002] 目前,由于无线局域网(WLAN :Wireless Local Area Network)和有线网络相比, 具有支持移动计算、维护成本低廉、以及构架的灵活性、快捷性和可扩展性等诸多优点而成为目前研究的热点。 [0002] At present, due to the wireless local area network (WLAN: Wireless Local Area Network) and wired networks, compared with support for mobile computing, low maintenance costs, as well as architecture flexibility, speed and scalability and many other advantages become study hot spots. 通常,安装一个或多个无线接入点(AP=Access Point)设备就可建立覆盖整个建筑或者覆盖某一地区的局域网络,如此,无线客户端通过与其对应的无线接入点建立无线连接实现了接入无线局域网络的操作。 Typically, to install one or more wireless access points (AP = Access Point) can cover the whole building or a local area network coverage area, thus, the wireless client via the corresponding wireless access point establishes a wireless connection to achieve an access operation of the wireless local area network.

[0003] 参见图1,图1为现有技术中无线客户端的接入流程图。 [0003] Referring to FIG. 1, FIG. 1 is a flowchart illustrating the prior art wireless access client. 如图1所示,该流程包括以下步骤: As shown in FIG 1, the process comprising the steps of:

[0004] 步骤101,无线客户端扫描并获得其需要连接的无线接入点。 [0004] Step 101, the wireless client scans and obtains their wireless access point to be connected.

[0005] 这里,无线客户端可在其所支持的一个工作信道上主动扫描或被动扫描无线局域网络;之后,根据预设的规则获得对应的其需要连接的无线接入点。 [0005] Here, the wireless client at a working channel active scanning or passive scanning supports a wireless local area network; then obtain the wireless access point corresponding to its need to be connected according to a preset rule. 其中,该预设的规则可有多种实现形式,比如将其扫描得到的距离自己最近的无线接入点作为其需要连接的无线接入点等。 Wherein the preset rule may be implemented in many forms, such as the distance of their nearest wireless access point that scans obtained as wireless access points that want to connect.

[0006] 步骤102,无线客户端确定发送认证请求的工作模式,并在该工作模式上发送认证请求给上述无线接入点。 [0006] Step 102, the work mode wireless client sends an authentication request and transmits the authentication request to the operating mode of the wireless access point.

[0007] 这里,无线客户端支持的工作模式为工作模式a和工作模式g的任一种组合。 [0007] Here, the wireless client supports any combination of operating mode is a operating mode and operating mode of g. 其中,一个工作模式对应一个以上的工作信道,比如,工作模式g,其包含工作信道1、工作信道6和工作信道11。 Wherein an operation mode corresponding to more than one working channel, for example, operating modes g, comprising a working channel, the working channels 6 and working channel 11. 具体地,无线客户端确定发送认证请求的工作模式包括:无线客户端在其支持的工作信道中选择一个可用工作信信道,根据该工作信道即可确定当前需要选择的工作模式。 Specifically, the wireless client sends an authentication request to determine the mode of operation comprises: a wireless client selected communication channel is available in the working channel, it supports the work, the operating mode can be determined based on the need to select the currently operating channel.

[0008] 步骤103,无线接入点在接收到上述认证请求后,对该无线客户端进行认证,并发送认证响应给该无线客户端。 [0008] Step 103, the wireless access point after receiving the authentication request, authentication of the wireless client, and sends an authentication response to the wireless client.

[0009] 如果无线接入点还需要对发送认证请求的无线客户端执行关联操作,则还需要执行步骤104。 [0009] If the access point needs to transmit an authentication request associated with a wireless client to perform operations, the need to perform step 104.

[0010] 步骤104,无线客户端接收到上述认证响应后,在步骤102发送认证请求所用的工作模式上发送关联请求给无线接入点。 After [0010] Step 104, the wireless client receives the authentication response, the operating mode in step 102 sends an authentication request sent by the association request to the wireless access point.

[0011] 步骤105,无线接入点在接收到上述关联请求后,发送关联响应给该无线客户端。 [0011] Step 105, the wireless access point after receiving the association request, association response sent to the wireless client. 之后,无线接入点在步骤102所确定的工作模式上接入无线客户端。 Thereafter, the wireless access point on the operation mode determined in step 102 access to the wireless client.

[0012] 这里,步骤102中的认证请求和步骤104中的关联请求实质上是无线客户端发送的连接请求。 [0012] Here, the authentication request association in step 102 and step 104 requests a connection request is substantially transmitted by the wireless client. 至此,通过上述步骤,实现了一个无线客户端的无线接入。 Thus, through the above steps, to achieve a wireless access wireless client.

[0013] 但是,上述提供的现有方法中无线接入点没有对无线客户端的接入进行控制。 [0013] However, the above-described conventional method of providing a wireless access point wireless client no access control. 这样,若无线接入点对应多个相互独立的无线客户端,由于上述提供的现有方法没有对无线客户端的接入进行控制,就可能会使所有的无线客户端都会在同一工作模式上接入,而其他工作模式却相对比较空闲,如此,如此导致了无线接入点提供的无线网络得不到合理的利用,降低了无线客户端的接入性能。 Thus, if the wireless access point corresponding to a plurality of independent wireless clients, since the conventional control method described above does not provide access to the wireless client, it is possible to make all of the wireless clients are connected to the same mode of operation in, while others are relatively more free operation mode, so, thus resulting in the wireless network access point provides not reasonably use, reducing the access performance of the wireless client.

[0034] 如此,通过上述操作实现了无线客户端接入的控制方法。 [0034] Thus, by the above operation control method to realize a wireless client access.

[0035] 步骤203,直接接入该无线客户端。 [0035] Step 203, direct access to the wireless client.

[0036] 以上是对本发明实施例提供的方法的简单描述,下面结合具体实施例对上述方法进行详细描述。 [0036] The above is a brief description of the method according to an embodiment of the present invention, the following detailed description of the method described above with reference to specific embodiments.

[0037] 参见图3,图3为本发明实施例提供的无线客户端接入控制的详细流程图。 [0037] Referring to FIG. 3, FIG. 3 provides a detailed flowchart of wireless client access control embodiment of the invention. 本实施例中,以工作参数为无线客户端发送连接请求的工作模式为例。 In this embodiment, the operating parameters to the wireless client sends a connection request to the operating mode as an example. 需要说明的是,下述步骤301和步骤302为本发明实施例提供的信息收集(具体是收集各个无线客户端所支持的工作模式)操作,通过这两个步骤,可以很容易知道无线网络中各个无线客户端所支持的工作信道,进而根据无线客户端支持的工作信道获知该无线客户端所支持的工作模式;下述步骤303至步骤310为本发明实施例提供的针对发送连接请求的无线客户端的接入进行控制的操作。 Incidentally, (in particular collecting mode of each wireless client-supported) by the following steps 301 and 302 of the present invention, the information collecting operation according to an embodiment, by two steps, can easily know the wireless network respective wireless clients supported by the working channel, and thus to know the operating mode of the wireless clients supported by the wireless clients supported by the working channel; a step 303 to step 310 the radio for transmitting the connection request according to an embodiment of the present invention. access client performs operation control. 如图3所示,该流程可包括以下步骤: As shown in FIG. 3, the flow includes the following steps:

[0038] 步骤301,无线客户端在其支持的所有可用工作信道上选择一个可用工作信道发送探测请求。 [0038] Step 301, the wireless client in which all available operating channels available to support selection of a working channel sends a probe request.

[0039] 本实施例中,该探测请求中携带发送该探测请求报文的无线客户端的标识信息。 [0039] In this embodiment, the probe request carries the identifier information of the transmitted probe request packet wireless client.

[0040] 具体地,该标识信息可为介质访问控制(MAC =Media Access Control)地址;优选地,MAC地址中可包含网络接口卡的厂商信息和由厂商指定的网络接口卡序列号信息,对于每一个无线客户端,MAC地址是惟一的。 [0040] Specifically, the identification information may be an address of a media access control (MAC = Media Access Control); manufacturer information and a network interface card serial number specified by the manufacturer Preferably, MAC address may include a network interface card, for each wireless client, MAC address is unique.

[0041] 需要说明的是,无线局域网络中的各个无线客户端是相互独立的,其发送探测请求的时间也是相互独立的,其可以相同,也可以不同。 [0041] Incidentally, each of the wireless client is a wireless local area network independent, transmit a probe request which is independent of time, which may be the same or different.

[0042] 步骤302,无线接入系统接收该探测请求,根据该探测请求所携带的MAC地址和接收该探测请求的工作信道建立无线客户端支持信道列表。 [0042] Step 302, the wireless access system receives the probe request, the wireless client support to establish a channel list based on the probe request and a MAC address carried in the received probe request a working channel.

[0043] 本实施例中,无线接入系统具体可为胖AP或者为瘦AP+无线接入控制器(AC);本实施例并未具体限定。 [0043] In this embodiment, the wireless access system may be particularly thin fat AP or AP + Wireless Access Controller (AC) of; the present embodiment is not particularly limited.

[0044] 比如,如果无线接入系统在工作信道1上接收到探测请求携带了客户端1的MAC 地址,记为MACl、工作信道6上接收到探测请求报文携带了客户端2的MAC地址,记为MAC2、 工作信道149上接收到探测请求报文携带了客户端3的MAC地址,记为MAC3 ;其中,工作信道1和工作信道6对应于工作模式g,而工作信道149对应于工作模式a,则提取出各个探测请求携带的客户端的MAC地址,创建包含MAC地址和工作信道标识的对应关系的无线客户端支持信道列表,具体可参见表1所示: [0044] For example, if a wireless access system receiving the probe on the working channel 1 request includes the client MAC address 1, denoted MACl, received 6 working channel to the probe request packet the client MAC address 2 , denoted MAC2, received the probe request message carries the client MAC address 3, denoted MAC3 working channel 149; wherein the working channel 1 and the working channel 6 corresponds to g in the operating mode, the working channel 149 corresponding to the work patterns a, extracts the MAC address of the client carried in each probe request, create a wireless client comprising a mapping between the MAC address and the working end of the channel identification support channel list, may specifically shown in Table 1:

[0045] 表1 [0045] TABLE 1

[0046] [0046]

[0047] 本实施例中的无线客户端支持信道列表可动态更新和增加。 [0047] In this example embodiment the client-side support for the radio channel list can be dynamically updated and increased. 比如,当建立无线客户端支持信道列表之后,若无线接入系统又在工作信道11 (该工作信道11对应于工作模式g)接收到一个新的无线客户端即客户端4发送的探测请求,则提取出该探测请求携带的客户端4的MAC地址,记为MAC4,之后,将该MAC4和工作信道11的对应关系添加到上述无线客户端支持信道列表中。 For example, when establishing a wireless client support channel list, if the wireless access system and the working channel 11 (the working channel 11 corresponding to the operation mode g) received a new wireless client i.e. the client 4 probe request transmitted, the client extracts the probe request carries the MAC address 4, denoted MAC4, after addition of the correspondence relationship MAC4 working channel 11 and to support the wireless client in the channel list.

[0048] 需要说明的是,无线客户端在发送探测请求后,由于客户端可在无线局域网络中漫游,因此,无线客户端在发送探测请求后,会按照预设时间定期切换到其所支持的其他可用工作信道上再次发送探测请求。 [0048] Incidentally, the wireless client after sending the probe request, roaming because the client in a wireless local area network, and therefore, the wireless client after sending the probe request, it switches to the support regularly according to a preset time other useful working channel transmits a probe request again. 其中,该预设时间可根据实际情况进行设置,通常,该预设时间的单位可为毫秒(ms),并且各个无线客户端对应的预设时间相互独立。 Wherein, the predetermined time can be set according to actual situation, usually, the predetermined time may be a unit of milliseconds (MS), and the respective wireless client corresponding to a preset time independent. 比如,若客户端1切换工作信道发送探测请求的预设时间为10ms,当建立无线客户端支持信道列表之后,假如无线接入系统接收到的探测请求可为该客户端1在达到IOms后切换到其所支持的另一个可用工作信道比如工作信道6发送的。 For example, if the UE transmits a channel switching operation preset time probe request is 10ms, after the establishment of the wireless clients supported channel list, if the wireless access system may be received probe request for the client 1 after reaching the switching IOms it works to another available channel to support work such as the transmission channel 6. 如此,本步骤302中,无线接入系统提取出该探测请求携带的MAC1,将该MACl和工作信道6的对应关系添加到上述无线客户端支持信道列表中,其他无线客户端也可执行类似客户端1的操作。 Thus, in this step 302, a wireless access system to extract the MAC1 carried in probe request to add the corresponding relationship between the MACl 6 and working channel to said wireless client is supported in the channel list, the client may also perform other wireless customers like 1, the operation ends. 假如通过上述步骤得到的更新后的无线客户端支持信道列表如表2所示: If the updated obtained by the above-described steps wireless clients supported channel list, as shown in Table 2:

[0049]表 2 [0049] TABLE 2

[0050] [0050]

[0051] 步骤303,无线客户端在其所支持的一个工作信道上发送连接请求。 [0051] Step 303, the wireless client sends a connection request in a working channel it supports.

[0052] 优选地,上述连接请求具体可为现有技术中的认证请求和关联请求类似。 [0052] Preferably, the connection request is a request may be similar to the specific authentication request and associated prior art. 其中,该连接请求中可携带无线客户端的MAC地址。 Wherein, the connection request may carry the MAC address of the wireless client.

[0053] 这里,当前发送连接请求的无线客户端的个数可有多个,本实施例只针对其中一个无线客户端来描述,其余类似。 [0053] Here, the current connection request transmits a wireless client terminal number may be a plurality, only for the present embodiment wherein a wireless client will be described, the remaining similar. 为便于描述,本实施例将上述发送连接请求的无线客户端所选择的工作信道记为工作信道1。 For ease of description, the above-described embodiment of the present embodiment transmits a connection request to the wireless client selected working channel referred to as a working channel.

[0054] 步骤304,无线接入系统确定出该无线客户端发送连接请求的工作模式。 [0054] Step 304, it is determined that a wireless access system operating mode of the wireless client sends a connection request. [0055] 比如,若上述步骤303中,无线客户端1在工作信道1上发送连接请求,则本步骤304中无线接入系统在工作信道1上接收到连接请求,进而可根据工作信道1确定无线客户端1发送连接请求的工作模式为工作模式g。 [0055] For example, if the above step 303, the wireless client 1 sends a connection request on the working channel 1, then this step 304 a radio access system receives a connection request on the working channel 1, and further may be determined according to the working channel 1 operating mode wireless client sends a connection request to the operation mode 1 g.

[0056] 步骤305,判断步骤304确定的工作模式是否已接入了预设阈值个无线客户端,如果是,执行步骤306,否则,执行步骤309。 [0056] Step 305, decision step 304 determines whether the operation mode has access to a preset threshold wireless client, if yes, step 306 is performed, otherwise, step 309 is executed.

[0057] 这里,预设阈值可根据工作模式的工作频段或者其他实际情况进行设置,本实施例并不具体限定。 [0057] Here, the preset threshold value may be set according to the operating mode of the operating band or other practical circumstances, the present embodiment is not particularly limited.

[0058] 步骤306,判断发送连接请求的无线客户端是否仅支持步骤304确定的工作模式, 如果是,执行步骤307 ;否则,执行步骤310。 [0058] Step 306 determines whether the wireless connection request transmits client only supports the operating mode determined in step 304, if yes, perform step 307; otherwise, step 310 is performed.

[0059] 这里,判断发送连接请求的无线客户端是否仅支持步骤304确定的工作模式是根据上述建立和更新的无线客户端支持信道列表来执行的,具体是:根据该连接请求携带的无线客户端的MAC地址,在上述建立的无线客户端支持信道列表中查找该MAC地址是否还对应除步骤304确定的工作模式所包含的工作信道之外的其他工作信道,如果是,确定发送连接请求的无线客户端不仅支持步骤304确定的工作模式,还支持其他的工作模式;否则,当在上述建立的无线客户端支持信道列表中查找出该MAC地址仅对应步骤304确定的工作模式所包含的一个或多个工作信道,则确定发送连接请求的无线客户端仅支持步骤304确定的工作模式。 [0059] Here, it is determined whether to transmit a connection request to the wireless client supports only operation mode in step 304 determination is performed based on the establishment of newer wireless clients supported channel list and, in particular: requesting wireless client carried in accordance with the connection MAC address of the client, find out if the MAC address also corresponds to the other working channel in addition to a working channel in step 304 determines the operation mode included in the support channel list, the wireless client established above, and if so, to determine transmits a connection request to the radio client only supports the working mode in step 304 is determined, and also support other modes of operation; otherwise, when the find out the MAC address only steps supported channel list, the wireless client established above 304 determines the operation mode contained in one or a plurality of operating channels, it is determined that the wireless terminal transmits a connection request the client only supports the operating mode determined in step 304.

[0060] 比如,若步骤304确定的工作模式为工作模式g,则根据该连接请求携带的无线客户端的MAC地址,在上述建立的无线客户端支持信道列表中查找该MAC地址是否还对应工作模式g所包含的工作信道(工作信道1、工作信道6和工作信道11)之外的其他工作信道,若查找出该MAC地址还对应工作信道149,则确定该MAC地址对应工作模式a,进而确定发送连接请求的无线客户端不仅支持工作模式g,还支持工作模式a ;否则,当上述建立的无线客户端支持信道列表中该MAC地址仅对应工作模式g包含的工作信道,比如,仅对应工作信道1、工作信道6和工作信道11种的任意一种组合,则确定该MAC地址仅对应工作模式g,进而确定发送连接请求的无线客户端仅支持工作模式g。 [0060] For example, if the working mode in step 304 is determined for the mode of g, the MAC address of the connection request includes wireless client to find whether the MAC address also corresponds to operating mode supported channel list, the wireless client above an established g included in the working channel (working channel 1, working channels 6 and working channel 11) other working channel outside, if it can find out the MAC address also corresponds to the working channel 149, it is determined that the MAC address corresponding to the operation mode a, and then determine transmits a connection request to the wireless client only supports operating modes g, also supports operating mode a; otherwise, when said established wireless client supports the operating channel in the channel list of the MAC address only operation mode g comprising, for example, only the corresponding work channel 1, any combination of the 11 kinds of the working channel and working channel 6, it is determined that the MAC address corresponding to the operating mode only g, and further determines the wireless client sends a connection request to the operating mode only supports g.

[0061] 需要说明的是,若判断出该连接请求携带的MAC地址不存在于上述无线客户端支持信道列表中,则本实施例可直接执行步骤309。 [0061] Incidentally, if it is determined that the MAC address carried in the connection request does not exist in the wireless client support in the channel list, then the present embodiment can execute step 309 directly.

[0062] 还需要说明的是,步骤305和步骤306并未有固定的时间先后顺序,其也可先执行步骤306,具体为:判断所述无线客户端是否仅支持所述工作模式,如果是,执行步骤305, 否则,执行步骤310。 [0062] It is further noted that step 305 and step 306 does not have a fixed time sequence, which may also be performed before step 306 specifically comprises: determining whether the wireless client only supports the working mode, if , step 305 is executed, otherwise, step 310. 如此,步骤305具体可为:判断无线客户端发送连接请求的工作模式是否已接入了预设阈值个无线客户端,如果是,执行步骤307;否则,执行步骤309。 Thus, step 305 may specifically be: determining whether the wireless client sends a connection request to the access mode of operation has been preset threshold wireless client, if yes, perform step 307; otherwise, step 309 is executed.

[0063] 步骤307,判断在步骤304确定的工作模式上接入的所有无线客户端中是否存在同时还支持其他工作模式的无线客户端,如果是,则执行步骤308 ;否则,执行步骤309。 [0063] Step 307 determines whether there is also supports other operating modes of the wireless clients to all clients in the wireless mode of access is determined in step 304, if yes, performing step 308; otherwise, step 309 is executed.

[0064] 这里,判断在步骤304确定的工作模式上接入的所有无线客户端中是否存在同时还支持其他工作模式的无线客户端是根据上述建立和更新的无线客户端支持信道列表来执行的,具体是:若步骤304确定的工作模式为工作模式g,则针对在工作模式g上接入的每一个无线客户端,在上述无线客户端支持信道列表中查找该无线客户端的MAC地址;之后,确定该MAC地址对应的工作信道的标识,如果该MAC地址对应的工作信道除了工作模式g所包含的工作信道之外,还有其他工作信道的标识,比如工作信道149,则确定该无线客户端除了工作模式g之外还同时支持工作模式a,因此,判断出在工作模式g上接入的所有无线客户端中存在同时还支持其他工作模式的无线客户端的无线客户端;否则,判断出不存在除了工作模式g之外还同时支持工作模式a的无线客户端。 [0064] Here, it is determined whether there is also supports other operating modes of the wireless clients to all wireless clients in the working mode in step 304 determines whether the access is based on the establishment and updating wireless clients supported channel list to be executed , specifically: If the working mode in step 304 is determined for the mode of g, then for each wireless client in working mode g access look for the MAC address of the wireless client in the wireless client supports the channel list; determining operating channel identifier of the MAC address, and if the MAC address corresponding to a working channel in addition to a working channel working mode g included, as well as identifying other working channel, such as working channel 149, it is determined that the wireless client in addition to the end of the operating mode operating mode also supports g a, and therefore, it is determined that all the wireless clients on the working mode of the access g present in other operating modes also support wireless client wireless client; otherwise, it is determined in addition to the mode of operation also supports g operating mode of a wireless client does not exist.

[0065] 步骤308,断开支持其他工作模式的无线客户端在步骤304确定的工作模式上的连接。 [0065] Step 308, the operation mode of the disconnect support other wireless clients connected to the operation mode determined in step 304. 之后,执行步骤309。 Then, step 309 is executed.

[0066] 这里,若上述步骤307判断出有多个无线客户端除了支持304确定的工作模式外, 还支持其他工作模式,则本步骤308可随意断开其中一个在304确定的工作模式上接入的无线客户端。 [0066] Here, if the above-described step 307 it is determined that a plurality of wireless clients 304 in addition to supporting the determined operation mode, it also supports other operating modes, this step 308 can be freely connected to the disconnecting one of the determined operation mode 304 the wireless client.

[0067] 步骤309,在步骤304确定的工作模式上接入发送连接请求的无线客户端。 [0067] Step 309, the access client sends a radio connection request in step 304 determines the operation mode. 结束当前流程。 The end of the current process.

[0068] 步骤310,丢弃该连接请求,当接收到该无线客户端在除步骤304确定的工作模式外的其他工作模式上发送的连接请求时,再接入该无线客户端。 [0068] Step 310, the connection request is discarded, when the connection of the other operating modes the transmission operating mode the outer receiving the wireless client 304 in addition to the step of determining the request, then access to the wireless client. 结束当前流程。 The end of the current process.

[0069] 这里,步骤306判断出无线客户端还支持其他工作模式时,可根据该无线客户端需要接入网络的紧急情况或者其他实际情况来确定当前是否需要执行步骤310。 When [0069] Here, step 306 determines that the wireless client also supports other operating modes, may determine whether the current need to perform step 310 on an emergency basis to the wireless client needs to access a network or other practical circumstances. 比如,如果该无线客户端需要接入无线网络的优先级不高,则可执行步骤310 ;否则,也可直接执行步骤309或者执行步骤307,具体情况需要具体分析。 For example, if the wireless client needs to access the wireless network is not high priority, step 310 may be executed; otherwise, step 309 may be performed directly or step 307, where the specific needs of a particular analysis. 本实施例仅以步骤306判断出无线客户端还支持其他工作模式时,执行步骤310为例,其仅是一种举例,不应理解为一种限制。 The present embodiment only when step 306 determines that the wireless client also supports other operating modes, step 310 is performed, for example, which is only a way of example, should not be construed as a limitation.

[0070] 如此,实现了无线客户端接入的控制流程。 [0070] Thus, the control flow to achieve a wireless client access.

[0071] 需要说明的是,无线客户端在支持多个工作模式时,比如在同时支持工作模式a 和工作模式g时,其通常会默认在工作模式g上发送连接请求。 [0071] Incidentally, when the wireless client supports a plurality of operating modes, such a support mode of operation and mode of g, which typically transmits a connection request on the default mode of operation g. 为了实现工作模式的均衡利用,本实施例也可执行图4所示的流程。 In order to achieve balanced use of the mode of operation, the present embodiment may also perform the process shown in FIG. 参见图4,图4为本发明实施例提供的无线客户端接入控制的另一详细流程图。 Referring to FIG. 4, FIG. 4 another detailed flowchart of a wireless client access control of the embodiment of the present invention. 如图4所示,该流程可包括以下步骤: 4, the flow includes the following steps:

[0072] 步骤401至步骤403分别与图3所示的步骤301至步骤303类似,这里不再赘述。 Each step shown in FIG. 3 [0072] Step 401 to step 301 to step 403 is similar to 303, is not repeated here.

[0073] 步骤404,无线接入系统确定出该无线客户端发送连接请求的工作模式是否为工作模式g,如果是,执行步骤405,否则,直接在该发送连接请求的工作模式上接入无线客户端。 [0073] Step 404, it is determined that a wireless access system of the wireless client sends a connection request whether the operation mode of the operation mode g, if yes, step 405 is performed, otherwise, the radio access directly on the working mode of the connection request transmitted clients.

[0074] 步骤405,判断该无线客户端是否仅支持所述工作模式g,如果否,执行步骤406, 如果是,执行步骤407。 [0074] Step 405 determines whether the wireless client only supports the working mode g, if not, step 406 is performed, if so, step 407 is executed.

[0075] 步骤406,丢弃该连接请求,当接收到该无线客户端在除工作模式g外的工作模式上发送的连接请求时,在该工作模式上接入所述无线客户端。 [0075] Step 406, the connection request is discarded, when receiving the connection request sent by the wireless client in addition to the operating mode of the operating modes g, on the mode of access to the wireless client. 结束流程。 The end of the process.

[0076] 比如,若步骤405判断出无线客户端除了支持工作模式g外还支持工作模式a,则本步骤406丢弃该连接请求,当接收到该无线客户端在工作模式a上发送的连接请求时,在该工作模式a上接入无线客户端。 [0076] For example, if step 405 determines that the wireless client in addition to support for the work mode of g external supports operation mode a, the present step 406 discards the connection request when receiving the connection request to the wireless client sends on the working mode of a when, on the mode of access to a wireless client.

[0077] 步骤407,判断工作模式g是否已接入了预设阈值个无线客户端,如果是,执行步骤408,否则,执行步骤410。 [0077] Step 407, it is determined whether the operation mode has accessed g preset threshold wireless client, if yes, step 408 is performed, otherwise, step 410 is performed.

[0078] 步骤408,判断工作模式g上接入的所有无线客户端中是否存在同时还支持其他工作模式的无线客户端,如果是,则执行步骤409 ;否则,执行步骤410。 [0078] Step 408, all clients access to the operating mode is judged whether or not there g also supports other operating modes of the wireless client, if yes, execute step 409; otherwise, step 410 is performed.

[0079] 步骤409,断开支持其他工作模式的无线客户端在步骤304确定的工作模式上的连接。 [0079] Step 409, the operation mode of the disconnect support other wireless clients connected to the operation mode determined in step 304. 之后,执行步骤410。 Thereafter, step 410 is performed. [0080] 步骤410,在工作模式g上接入发送连接请求的无线客户端。 [0080] Step 410, the access client sends a radio connection request on the working mode g. 结束当前流程。 The end of the current process.

[0081] 需要说明的是,为便于简单操作,在步骤405判断出所述无线客户端仅支持工作模式g时,也可直接在该工作模式g上接入该发送连接请求的无线客户端,不执行后续的步骤407至步骤409,具体情况需要具体分析,上述操作只是一种举例,并非为一种限制。 [0081] Incidentally, when it simple to operate, at step 405 it is determined that the client only supports wireless operating modes g, also the access to the wireless client sends a connection request directly on the mode of g, without a subsequent step 409 to step 407, where the specific needs of a particular analysis, the above operation is only a way of example and not as a limitation.
