技术领域technical field

本发明涉及通信技术领域，尤其涉及一种WLAN准入方法及装置。The present invention relates to the technical field of communications, in particular to a WLAN access method and device.

背景技术Background technique

目前，随着如智能手机、平板电脑等移动终端的飞速发展，利用无线网络进行数据业务已成为传输信息的重要方式之一。在无线网络中，WLAN（Wireless Local Area Network；无线局域网）以移动性高、成本低、建设速度快的优势，承载越来越多的无线数据流量。At present, with the rapid development of mobile terminals such as smart phones and tablet computers, using wireless networks for data services has become one of the important ways of transmitting information. In wireless networks, WLAN (Wireless Local Area Network; Wireless Local Area Network) carries more and more wireless data traffic with its advantages of high mobility, low cost, and fast construction speed.

在WLAN中，应用WLAN网络的每一个客户端共享带宽接入到AP（AccessPoint；接入点）上。为了防止AP上因客户端数目过多而影响接入到该AP的所有客户端的正常使用，以及防止AP负载过大而造成设备死机的问题，通常采用限制接入到每一个AP上的客户端数量的方法来加强对WLAN网络的管理，即预设每一个AP允许接入客户端的阈值。当一个AP上的客户端接入数量达到上述阈值，即会拒绝所有新客户端的接入请求，直至存在已接入上述AP的至少一个客户端离开，才能在该AP上接入新的客户端。In a WLAN, each client using the WLAN network shares bandwidth to access an AP (AccessPoint; access point). In order to prevent the excessive number of clients on the AP from affecting the normal use of all clients connected to the AP, and to prevent the device from crashing due to excessive load on the AP, it is usually used to limit the clients connected to each AP. There are several ways to strengthen the management of the WLAN network, that is, to preset the threshold for each AP to allow access to clients. When the number of client access on an AP reaches the above threshold, all new client access requests will be rejected until at least one client that has already connected to the above AP leaves, and new clients can be connected to the AP. .

在连接到WLAN中的客户端中，可能存在占用接入名额而未进行数据业务的客户端，例如，自动接入WLAN的客户端；或者，存在仅占用较少流量的客户端，例如，仅使用即时通讯工具进行数据业务的客户端。上述客户端虽然不进行数据业务，或者仅进行少量数据业务，但仍占用AP的允许接入名额。当接入一个AP的客户端数量达到其阈值时，对于迫切需要使用网络的客户端，或者进行传输文件等大流量业务的客户端，就会因为接入上述AP的客户端数量达到其阈值而被拒绝接入。Among the clients connected to the WLAN, there may be clients that occupy the access quota but do not perform data services, for example, clients that automatically access the WLAN; or, there may be clients that only occupy less traffic, for example, only Clients who use instant messaging tools for data services. Although the above clients do not perform data services, or only perform a small amount of data services, they still occupy the allowed access quota of the AP. When the number of clients connected to an AP reaches its threshold, clients that urgently need to use the network, or clients that perform large-traffic services such as file transfers, will be shut down because the number of clients connected to the above-mentioned AP reaches its threshold. Access denied.

为了解决上述问题，现有技术中，通常采用对客户端进行划分来解决WLAN接入的问题：In order to solve the above problems, in the prior art, the client is usually divided to solve the problem of WLAN access:

将客户端划分为认证客户端和未认证客户端，在无线设备侧侦听客户端和认证服务器之间的认证报文，获知连接到AP上的客户端是否为通过认证的有效客户端。当认证客户端请求接入某AP，并且接入该AP的客户端数量已达到其阈值时，强制未认证客户端离开，使认证客户端接入上述AP。采用上述技术方案，仅根据认证机制将客户端进行划分，当存在认证客户端并未使用网络资源进行数据业务，且上述AP的接入客户端数量已达到其阈值时，其他更高优先级的客户端仍会被拒绝接入上述AP。Divide clients into authenticated clients and unauthenticated clients, listen to the authentication message between the client and the authentication server on the wireless device side, and learn whether the client connected to the AP is a valid client that has passed the authentication. When an authenticated client requests to access an AP, and the number of clients accessing the AP reaches its threshold, the unauthenticated client is forced to leave, and the authenticated client is allowed to access the AP. Using the above technical solution, the clients are only divided according to the authentication mechanism. When there are authenticated clients that do not use network resources for data services, and the number of access clients of the above-mentioned AP has reached its threshold, other higher priority Clients will still be denied access to the above APs.

或者，根据客户端优先级来控制接入AP的客户端。统计接入AP的客户端数量以及请求接入上述AP的客户端数量之和，当该数量之和超过允许接入AP的客户端数量阈值，且请求接入上述AP的客户端为高优先级客户端时，强制低优先级客户端离开，使高优先级客户端接入上述AP。采用上述技术方案，当接入AP的客户端数量已经超过了上限，客户端无法获得IP地址，即无法将该客户端的等级信息发送至AP，将导致高优先级客户端无法接入WLAN。Alternatively, the clients accessing the AP are controlled according to the client priority. Count the number of clients accessing the AP and the sum of the number of clients requesting access to the above-mentioned AP. When the sum of the numbers exceeds the threshold of the number of clients allowed to access the AP, and the client requesting to access the above-mentioned AP is a high priority Forcing low-priority clients to leave, allowing high-priority clients to connect to the above APs. With the above technical solution, when the number of clients accessing the AP has exceeded the upper limit, the client cannot obtain an IP address, that is, the class information of the client cannot be sent to the AP, which will cause high-priority clients to be unable to access the WLAN.

综上所述，目前对WLAN的接入均是基于客户端能够获取WLAN接入系统分配的IP地址，客户端的接入请求消息能够送达WLAN网络，当接入AP上的客户端数量已经超过该AP的上限时，客户端无法获得IP地址，即无法将该客户端的等级信息发送至WLAN网络，将导致高优先级客户端无法接入WLAN。To sum up, the current access to WLAN is based on the fact that the client can obtain the IP address assigned by the WLAN access system, and the client's access request message can be delivered to the WLAN network. When the number of clients connected to the AP exceeds When the upper limit of the AP is reached, the client cannot obtain an IP address, that is, the client's level information cannot be sent to the WLAN network, which will cause high-priority clients to be unable to access the WLAN.

下面结合附图对本发明优选的实施方式进行详细说明。Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

基于上述技术方案，参阅图1所示，本发明实施例中，接入WLAN网络的详细流程如下：Based on the above technical solution, referring to Fig. 1, in the embodiment of the present invention, the detailed process of accessing the WLAN network is as follows:

步骤100：接收第一客户端发送的请求接入消息，获取该请求接入消息中携带的网络信息以及第一客户端信息。Step 100: Receive an access request message sent by the first client, and acquire network information and first client information carried in the access request message.

本发明实施例中，第一客户端向网络侧发送消息请求接入WLAN，当第一客户端搜索范围内所有AP均达到其接入数量上限，即第一客户端请求接入WLAN失败时，则第一客户端通过移动通信网络向WLAN准入装置发送请求接入消息，该请求接入WLAN。上述请求接入消息中，携带第一客户端的网络信息以及第一客户端信息。In the embodiment of the present invention, the first client sends a message to the network side to request access to the WLAN. When all the APs within the search range of the first client reach the upper limit of the access number, that is, when the first client fails to request access to the WLAN, Then the first client sends an access request message to the WLAN access device through the mobile communication network, the request for accessing the WLAN. The foregoing access request message carries network information of the first client and information of the first client.

本发明实施例中，可以第一客户端中存储WLAN准入装置的标识信息，当第一客户端请求接入WLAN失败时，即会获取第一客户端的网络信息以及第一客户端信息。第一客户端根据WLAN准入装置的标识信息通过移动通信网络，向WLAN准入装置发送请求接入消息。较佳的，可以采用短消息形式向WLAN准入装置发送请求接入消息。利用移动通信网络向WLAN准入装置发送短消息，无须为第一客户端分配IP地址即可使WLAN准入装置获取第一客户端的网络信息以及第一客户端信息，避免了当第一客户端搜索范围内所有AP均达到其接入数量上限时，第一客户端无法获取IP地址并将其请求接入消息发送至WLAN准入装置的问题。并且，采用移动通信网络与WLAN多网协同的方式，对WLAN改造小，实现过程方便快捷。In the embodiment of the present invention, the identification information of the WLAN access device can be stored in the first client, and when the first client fails to request to access the WLAN, the network information of the first client and the first client information will be obtained. The first client sends an access request message to the WLAN admission device through the mobile communication network according to the identification information of the WLAN admission device. Preferably, the access request message may be sent to the WLAN access device in the form of a short message. Using the mobile communication network to send a short message to the WLAN access device, the WLAN access device can obtain the network information of the first client and the first client information without assigning an IP address to the first client, avoiding being the first client When all the APs within the search range reach their access limit, the first client cannot obtain an IP address and send its access request message to the WLAN access device. In addition, the mobile communication network and the WLAN multi-network synergy mode are adopted, so that the modification of the WLAN is small, and the implementation process is convenient and quick.

上述移动通信网络可以为2G网络，也可以为3G网络或者4G网络；请求接入消息可以通过电路域发送，其中，电路域主要用于传送语音业务，目前短信同语音业务一样通过电路域传送；也可以通过分组域发送，其中，分组域主要用于传送数据业务，短信也可以通过分组域传送。上述电路域和分组域的网元不同，信令也不同。The above-mentioned mobile communication network can be a 2G network, a 3G network or a 4G network; the access request message can be sent through the circuit domain, wherein the circuit domain is mainly used to transmit voice services, and currently short messages are transmitted through the circuit domain just like voice services; It can also be sent through the packet field, wherein the packet field is mainly used to transmit data services, and the short message can also be transmitted through the packet field. The above-mentioned network elements in the circuit domain and the packet domain are different, and the signaling is also different.

步骤110：根据上述网络信息，获取第一客户端搜索范围内所有AP的标识信息，以及根据第一客户端信息，获取第一客户端对应的客户端级别。Step 110: According to the above network information, obtain the identification information of all APs within the search range of the first client, and obtain the client level corresponding to the first client according to the first client information.

本发明实施例中，第一客户端的网络信息包括以下任意一项及其组合：至少一个SSID，第一客户端搜索范围内所有的AP对应的AP标识信息，每一个AP对应的电平值。特殊的，当第一客户端无法获取上述网络信息时，则将第一客户端所处位置的基站信息或者其他定位系统中的位置信息作为第一客户端的网络信息封装在请求接入消息中发送至WLAN准入装置，由WLAN准入装置根据上述基站信息或者位置信息解析第一客户端搜索范围内的所有AP及其相关信息。In the embodiment of the present invention, the network information of the first client includes any of the following items and combinations thereof: at least one SSID, AP identification information corresponding to all APs within the search range of the first client, and a level value corresponding to each AP. Specifically, when the first client cannot obtain the above network information, the base station information of the first client's location or the location information in other positioning systems is encapsulated as the network information of the first client in the access request message and sent To the WLAN admission device, the WLAN admission device analyzes all APs and related information within the search range of the first client according to the base station information or location information.

在通信系统中，AP的电平值表征该AP相对于第一客户端的信号强弱，其中，AP的电平值越高，表示该AP相对于第一客户端的信号越强。In the communication system, the level value of an AP represents the signal strength of the AP relative to the first client, wherein the higher the level value of the AP, the stronger the signal of the AP relative to the first client.

本发明实施例中，第一客户端信息包括第一客户端的身份标识〔如手机号码，客户端的MAC（Medium Access Control；媒体接入控制）地址等〕，第一客户端对应的客户端级别等信息。其中，客户端级别可以根据客户端选择的WLAN套餐类型，累计使用流量等信息进行判断。例如，客户端的WLAN套餐类型越高级则客户端对应的客户端级别越高；客户端累计使用流量越大，客户端级别越高。根据客户端的级别信息对所有客户端划分等级，从而保证了大流量客户端优先接入WLAN进行数据业务。In the embodiment of the present invention, the first client information includes the identity of the first client (such as mobile phone number, MAC (Medium Access Control; Media Access Control) address of the client, etc.), the corresponding client level of the first client, etc. information. Wherein, the client level can be judged according to information such as the WLAN package type selected by the client, the accumulated traffic usage, and the like. For example, the higher the WLAN package type of the client, the higher the client level corresponding to the client; the greater the cumulative traffic used by the client, the higher the client level. Classify all clients according to their class information, thus ensuring that clients with heavy traffic access WLAN preferentially for data services.

步骤120：分别确定接入获取的任意一个AP的标识信息对应的AP的所有客户端级别。Step 120: Determine all client levels of the AP corresponding to the obtained identification information of any AP.

本发明实施例中，WLAN准入装置获取第一客户端搜索范围内的所有AP，并获取接入每一个AP的所有客户端的身份标识，根据客户端的身份标识获取每一个客户端对应的客户端级别信息。WLAN准入装置可以将上述客户端的身份标识发送至运营商，由运营商查询每一个客户端对应的客户端级别信息发送至WLAN准入装置；WLAN准入装置也可以在本地保存一张客户端级别表，当一个新的客户端接入WLAN时，即判断该客户端对应的客户端级别，并将该客户端对应的客户端级别保存至该客户端接入的AP标识信息下，更新上述客户端级别表，当一个客户端断开与WLAN的连接时，即删除上述客户端级别表中对应的客户端，并根据运营商定期更新的客户端级别更新本地保存的客户端级别表，通过根据客户端的身份标识查询上述客户端级别表获取该客户端对应的客户端级别。In the embodiment of the present invention, the WLAN access device obtains all APs within the search range of the first client, and obtains the identity marks of all clients accessing each AP, and obtains the client corresponding to each client according to the identity marks of the clients. level information. The WLAN access device can send the identity of the above-mentioned client to the operator, and the operator can query the corresponding client level information of each client and send it to the WLAN access device; the WLAN access device can also store a client terminal locally. Level table, when a new client accesses WLAN, judge the client level corresponding to the client, and save the client level corresponding to the client under the AP identification information that the client accesses, and update the above Client level table, when a client disconnects from the WLAN, delete the corresponding client in the above client level table, and update the locally saved client level table according to the client level regularly updated by the operator, through Query the above client level table according to the identity of the client to obtain the corresponding client level of the client.

步骤130：依次检测接入到任意一个AP的各个客户端级别，并在判定接入任意一AP的所有客户端中存在级别低于第一客户端的至少一个其他客户端时，在上述至少一个其他客户端中选取第二客户端，指示断开第二客户端与对应AP之间的连接，将第一客户端接入所述第二客户端对应的AP。Step 130: sequentially detect the levels of each client connected to any AP, and when it is determined that there is at least one other client whose level is lower than the first client among all the clients connected to any AP, the at least one other client Selecting the second client from the clients, instructing to disconnect the connection between the second client and the corresponding AP, and connecting the first client to the AP corresponding to the second client.

具体为：Specifically:

本发明实施例中，按照每一个AP对应的电平值对第一客户端搜索范围内所有AP进行排序，按照上述电平值由高到低的顺序对第一客户端搜索范围内的所有AP进行排序。较佳的，将第一客户端搜索范围内的所有AP以AP列表形式显示，该AP列表包含每一个AP标识信息，以及每一个AP对应的电平值。上述AP列表按照每一个AP对应的电平值进行排序，高电平的AP位于AP列表的前端。特殊的，当第一客户端网络信息仅携带2G/3G/4G网络的基站信息或者其他定位系统中的位置信息时，则根据上述基站信息获取该基站对应的所有AP及其信息，或者根据上述位置信息获取该位置对应的所有AP及其信息。根据获取的上述AP及其信息，对第一客户端搜索范围内的所有AP进行排序。In the embodiment of the present invention, all APs within the search range of the first client are sorted according to the level value corresponding to each AP, and all APs within the search range of the first client are sorted according to the order of the above level values from high to low. Sort. Preferably, all APs within the search range of the first client are displayed in the form of an AP list, and the AP list includes identification information of each AP and a level value corresponding to each AP. The above AP list is sorted according to the level value corresponding to each AP, and the AP with high level is at the front end of the AP list. Specifically, when the first client network information only carries base station information of the 2G/3G/4G network or location information in other positioning systems, all APs and their information corresponding to the base station are obtained according to the above base station information, or according to the above The location information obtains all APs and their information corresponding to the location. All APs within the search range of the first client are sorted according to the acquired APs and the information thereof.

较佳的，在上述AP列表中，将第一客户端搜索范围内的所有AP按照电平高低进行排序后，将接入上述每一个AP的所有客户端分别对应的客户端身份标识、客户端级别等信息保存至AP列表中。Preferably, in the above AP list, after sorting all the APs within the search range of the first client according to their level, the client IDs, client IDs, and Level and other information are saved to the AP list.

按照上述所有AP的排序，按照AP的电平值由高到低依次检测接入到每一个AP的各个客户端级别，当接入第一个AP的所有客户端均不符合条件时，则检测接入第二个AP的所有客户端，以此类推。采用上述技术方案，能够保证接入电平值最高的AP的所有客户端被优先检测，从而确保将第一客户端优先接入到信号强度最高的AP上。According to the sorting of all the above APs, the level of each client connected to each AP is detected in turn according to the level value of the AP from high to low. When all the clients connected to the first AP do not meet the conditions, the detection All clients connected to the second AP, and so on. By adopting the above technical solution, it can be ensured that all clients of the AP with the highest access level are preferentially detected, thereby ensuring that the first client is preferentially connected to the AP with the highest signal strength.

当检测到接入某一个AP的各个客户端中存在级别低于第一客户端的至少一个其他客户端时，记录上述至少一个其他客户端对应的身份标识，并从上述至少一个其他客户端中随机选择第二客户端，或者从上述至少一个其他客户端中选择级别最低的客户端作为第二客户端，通知WLAN接入系统强制上述第二客户端断开与WLAN的连接，仅允许第一客户端进行接入；并通过移动通信网络向第一客户端发送可接入AP消息，提示第一客户端向WLAN接入系统再次发送接入请求消息；当WLAN接入系统再次接收到第一客户端发送的WLAN接入请求消息，即将第一客户端接入至低优先客户端对应的AP上。其中，上述WLAN接入系统可以为AP，也可以为AC（Access Controller；接入控制器）。When it is detected that there is at least one other client with a lower level than the first client among the clients accessing a certain AP, record the identity corresponding to the at least one other client, and randomly select the client from the at least one other client. Select the second client, or select the client with the lowest level from the at least one other client as the second client, notify the WLAN access system to force the second client to disconnect from the WLAN, and only allow the first client to and send an accessable AP message to the first client through the mobile communication network, prompting the first client to send an access request message to the WLAN access system again; when the WLAN access system receives the first client again The WLAN access request message sent by the terminal, that is, the first client is connected to the AP corresponding to the low-priority client. Wherein, the above-mentioned WLAN access system may be an AP or an AC (Access Controller; access controller).

较佳的，一旦检测到接入某一个AP的各个客户端中存在级别低于第一客户端的一个其他客户端时，则停止上述检测过程，并记录上述其他客户端对应的身份标识信息，通知WLAN接入系统强制上述其他客户端断开与WLAN的连接，仅允许第一客户端进行接入；并通过移动通信网络向第一客户端发送可接入AP消息，提示第一客户端向WLAN接入系统再次发送接入请求消息；当WLAN接入系统再次接收到第一客户端发送的接入请求消息，即将第一客户端接入至低等级客户端对应的AP上。Preferably, once it is detected that there is one other client with a level lower than the first client in each client connected to a certain AP, the above-mentioned detection process is stopped, and the identity information corresponding to the above-mentioned other clients is recorded, and the notification The WLAN access system forces the above-mentioned other clients to disconnect from the WLAN, and only allows the first client to access; The access system sends the access request message again; when the WLAN access system receives the access request message sent by the first client again, it will connect the first client to the AP corresponding to the low-level client.

特殊的，当在上述检测过程中，某一个客户端断开与WLAN的连接，即检测到存在空闲AP时，选择空闲AP进行接入。较佳的，优先检测所有AP中是否存在空闲AP，当存在空闲AP时，选择空闲AP进行接入；当不存在空闲AP时，则检测接入到所有AP的各个客户端中是否存在级别低于第一客户端的其他客户端。采用较佳的技术方案，能够尽量少地强制低等级客户端断开WLAN连接，从而保证了接入到AP的所有客户端正常进行数据业务。Specifically, when a certain client disconnects from the WLAN during the above detection process, that is, when an idle AP is detected, the idle AP is selected for access. Preferably, it is preferred to detect whether there is an idle AP in all APs. When there is an idle AP, select an idle AP for access; other clients than the first client. By adopting a better technical solution, it is possible to force low-level clients to disconnect from the WLAN as little as possible, thereby ensuring that all clients connected to the AP normally perform data services.

当接入上述所有AP的所有客户端中均不存在级别低于第一客户端，且不存在空闲AP时，则通过移动通信网络向第一客户端发送无法接入消息，该无法接入消息中携带无法接入WLAN的具体原因。When none of the clients accessing the above-mentioned APs has a level lower than that of the first client, and there is no idle AP, a message of being unable to access is sent to the first client through the mobile communication network, and the message of being unable to access Carry the specific reason why the WLAN cannot be accessed.

参阅图2所示，当第一客户端请求接入WLAN失败后，第一客户端与WLAN准入装置的信息交互过程如下：Referring to Figure 2, when the first client fails to request access to the WLAN, the information interaction process between the first client and the WLAN access device is as follows:

步骤200：第一客户端端通过移动通信网络向WLAN准入装置发送请求接入消息。Step 200: the first client terminal sends an access request message to the WLAN access device through the mobile communication network.

步骤330：根据每一个AP的电平值，对第一客户端搜索范围内的所有AP进行排序。Step 330: sort all the APs within the search range of the first client according to the level value of each AP.

本发明实施例中，获取请求接入消息中携带的所有AP的电平值，其中，AP1的电平值大于AP2的电平值，按照AP的电平值由高到低排序时，AP1位于AP2之前。In the embodiment of the present invention, the level values of all APs carried in the access request message are acquired, wherein the level value of AP1 is greater than the level value of AP2, and when the level values of APs are sorted from high to low, AP1 is located in Before AP2.

步骤340：检测接入到任意一个AP的各个客户端级别，判断是否存在空闲AP，若存在，则执行步骤350；否则，执行步骤360。Step 340 : Detect each client level connected to any AP, and judge whether there is an idle AP, and if yes, execute step 350 ; otherwise, execute step 360 .

步骤350：将第一客户端接入到上述空闲AP。Step 350: Connect the first client to the idle AP.

步骤360：判断接入任意一AP的所有客户端中存在级别低于第一客户端的至少一个其他客户端，若不存在，则执行步骤370；否则，执行步骤380。Step 360: Determine that there is at least one other client whose level is lower than the first client among all the clients accessing any AP, if not, execute step 370; otherwise, execute step 380.

步骤370：通过移动通信网络向第一客户端发送无法接入消息。Step 370: Send an access inaccessible message to the first client through the mobile communication network.
