Description

一种客户端无线接入方法、系统及其装置 A client wireless access method, system and apparatus

技术领域 FIELD

本发明涉及网络通信技术领域,特别是涉及一种客户端无线接入方法、系统及其装置。 The present invention relates to network communication technology field, particularly to a client wireless access method, system and apparatus.

背景技术 Background technique

WLAN(Wireless Local Access Network,无线局域网)技术是一种基于802.11系列标准的技术,和现存的以太局域网相比较而言,无线局域网技术有一个很大的不同,即该技术使用无线射频信号代替有线传输介质来发送和接收数据包。 WLAN (Wireless Local Access Network, wireless local area network) technology is a technology based on the 802.11 family of standards, and the existing comparison Ethernet LAN, wireless LAN technology has a very different, i.e., which uses radio frequency instead of the signal cable transmission medium to transmit and receive packets. 作为无线局域网的一个重要组成部分的AP(Access Point,无线接入设备)是将从有线网络(例如因特网)接收到的数据转换成无线信号发送,并将接收到的无线信号转换成数据并转发到有线网络。 As an important part of a wireless LAN AP (Access Point, wireless access device) is converted from data received wired network (e.g. the Internet) into a wireless signal transmitted and received radio signal into data and forwards to a wired network.

但是WLAN在企业、机场等环境下大规模应用时,由于无线射频接入的开放性,很有可能出现多个客户端同时接入同一个AP的情况,从而造成AP超过其所能承受的负载极限,影响网络的传输性能。 However, when large-scale application in the enterprise WLAN, airports and other environment, the openness of the radio frequency access, is likely to have multiple clients simultaneously access the same case the AP, resulting in more than it can bear the load of AP limit the impact of network transmission performance. 因此负载均衡是解决上述问题的一个重要方法,负载均衡的目的是按照接入的客户端数或客户端流量进行负荷控制,让客户端负荷均匀地由在多个AP间进行负担,合理地平衡整个网络的负荷。 Load balancing is therefore important to solve the above problems, the object of balancing the load is controlled according to the load of the access number of clients or client traffic, allow client load evenly among a plurality of the burden of the AP, a reasonable balance of the whole load on the network. 一般将多个AP组成的逻辑组称为负载均衡组。 AP generally consisting of a plurality of logical groups referred to as load balancing group.

现有技术中需要通过命令行对属于同一个负载均衡组各个AP设备进行配置,即将有信号重叠区的AP作为邻居配置到同一个负载均衡组中,该负载均衡组的每个AP成员一般都用该AP的IP地址或者其它方法来标识。 Need in the art for each device belonging to the same AP load balancing group configure via the command line, i.e. there is overlap region AP signal to the same configuration as the neighbor load balancing group, each member of the AP load balancing group generally IP address of the AP, or other methods to identify.

现有技术中负载均衡组的配置通常由用户手工完成,如图1所示,一旦用户手工配置错误,即AP3与AP1、AP2无信号重叠,但用户将AP1、AP2和AP3配置到同一个负载均衡组,这会影响用户的接入。 Prior art load balancing group usually done manually by the configuration shown in Figure 1, once the user manual configuration errors, i.e., AP3 and AP1, AP2 no signal overlap, but the user will AP1, AP2 and AP3 to the same configuration load balancing group, this will affect the user's access. 此时,当客户端4准备通过AP3接入网络时,AP3会检查自己的负载和组内其它AP的负载,如果发现自己的负载大而其它AP负载小,则AP3拒绝客户端4的接入请求,并把客户端4的接入让给负载均衡组内的其它AP。 At this time, when the client 4 through the AP3 ready access network, AP3 will check their own load and the load other AP in the group, if a large load and find their other AP small load, AP3 denied access client 4 request, and to give the client access to the 4 load balancing group within the other AP. 但由于AP3和其它AP没有信号重叠区,即客户端4不在其他AP信号覆盖的范围内,导致客户端4无法接入其它AP,从而造成该用户无线接入网络失败。 However, since the AP does not AP3 and other signals overlap region, i.e. the other client signal coverage range of the AP is not 4, 4 can not cause the client to access another AP, resulting in the subscriber radio access network fails.

现有技术中,即便用户手工配置是正确的,但是仍然不知道是否负载均衡组的每个AP均能覆盖接入的客户端,因此依然会存在如图2所示的问题,客户端7准备接入到AP4时,如果AP4认为自己负载较大希望其接入到AP5中,则就会拒绝客户端7的接入请求,然而客户端7不在AP5的覆盖范围内无法接入AP5,使得客户端7还是无法接入网络。 In the prior art, even if the user manually configured correctly, but still we do not know whether the load of each AP can cover the access client balancing group, so problems still exist as shown in FIG. 2, the client 7 Preparation when access to the AP4, if a large load AP4 think they want to access their AP5, then the request will be denied access to the client 7, however, the client can not access AP5 AP5 not within the coverage area 7, such that the client end 7 still can not access the network. 因此负载均衡调度的准确性无法提高,用户往往需要经历过多的接入失败尝试。 Therefore, the accuracy can not be improved load balancing scheduling, users often need to go through too many failed access attempts.

具体实施方式 detailed description

下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述:本发明实施例的核心思想在于统一记录客户端的位置信息,即发现并确认客户端在哪些无线接入设备AP的覆盖范围内,这样就实现了对负载均衡组的自动发现,当一个客户端发送接入请求时,就可以很轻松的从该客户端所在的负载均衡组选择出一个最合适的AP供该客户端接入。 Below in conjunction with the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail: Core of example is a unified position information of client records, i.e., identifying and confirming the client coverage which wireless access device AP of embodiment of the present invention the, so to achieve automatic load balancing group discovery, when a client sends an access request, you can easily select the most appropriate AP for the client from the client the load balancing group is located into.

因此本发明实施例提出了两种客户端无线接入系统图,分别如图3和图4所示,其中客户端无线接入装置可以将AP通过有线口连接到该装置上,图3所示将该客户端无线接入装置置于无线控制器中,通过与各个AP均相连的无线控制器进行无线负载均衡的配置。 Thus, the present invention proposes two embodiments of a wireless access system FIG client, respectively, as shown in FIGS. 3 and 4, wherein the client access device may be a wireless AP via a wired connection port to the device, as shown in FIG. 3 the wireless client located in the radio access apparatus side controller, the wireless load balance configuration by the wireless controller are connected to each AP. 如图4所示也可以在各个AP之间能够通过协议相互交换各个AP的负载信息时,在至少一个AP上设置客户端无线接入装置,由设置了该客户端无线接入装置的AP统一进行负载均衡的配置。 As shown in FIG 4 may also be capable of exchanging load information of each AP by mutual agreement between the respective AP, configuring client devices in a radio access on at least one AP, wireless access device provided by a client of the AP unified load balancing configuration. 本发明实施例的关键在于通过客户端无线接入装置记录和维护客户端的位置信息,并在其发送请求后选择最合适的AP供其接入,因此该客户端无线接入装置无论集中放置还是分别放置均应涵盖在本发明实施例的保护范围之内。 Key embodiment of the invention is characterized by a radio access device for recording and maintaining the position of the client information of the client, and select the most appropriate AP after which it sends the request for access, so the wireless access device, whether the client is centrally located It should be disposed respectively within the scope of embodiments encompassed in the present invention.

如图3所示,为本发明实施例一种客户端无线接入系统。 3, the embodiment of a client wireless access system according to the present invention. 该系统包括至少一个客户端1、至少两个无线接入设备AP2和无线控制器3,AP2均与无线控制器3连接,AP2用于记录其覆盖范围内的客户端1的信息并上报给无线控制器3,具体为客户端1向AP2发送探测请求报文,AP2根据侦听到的探测请求报文,记录该客户端信息并上报;无线控制器3用于根据各AP2上报的其覆盖范围内的客户端信息建立包含客户端1与上报AP2对应关系的客户端表项后统一保存,该客户端表项包括客户端信息和上报该客户端信息的AP标识,其中客户端信息和AP标识为唯一标识该客户端和该AP的ID,例如该客户端的MAC地址,AP的IP地址。 The system 1 comprises at least one client, the at least two wireless access devices and the wireless controller 3 AP2, AP2 are connected to the wireless controller 3, a recording information for AP2 client terminal within its coverage area and reports to the radio the controller 3, a particular client request packet to send a probe AP2, AP2 listening request packet according to the detection, recording and reporting information to the client; wireless controller 3 is configured to report its respective coverage according AP2 after the client information in the establishing comprises client entry client 1 and the reporting AP2 correspondence relationship unified storage, the client entry includes client information and reports the client information AP identifier, wherein client information and AP identification that uniquely identifies the client and the AP ID, for example, the client's MAC address, IP address of the AP. 在客户端1向AP2发送接入请求时,AP2将该请求送交给无线控制器3进行处理,无线控制器3根据其保存的客户端表项,判断该客户端在哪些AP2的信号覆盖范围内,即自动发现对于当前客户端能够提供负载均衡的组成员,并检测该负载均衡组中AP的负载状况,根据检测到的负载均衡组中AP的负载状况,然后根据相应的负载均衡算法选择一个最合适的AP2供该客户端1接入,即从该客户端1所在的负载均衡组选择出一个负载最小的AP2供该客户端1接入。 When a client transmits an access request to AP2, AP2 the request sent to the controller 3 for processing the radio, the radio controller 3 saves the client entry, AP2 determines which signal coverage of the client inside, i.e., automatic discovery for the current client to provide group membership load balancing, and detecting a load condition of the load balancing group AP, according to the load status detected load balancing group AP, and then selected according to the appropriate load balancing algorithm one of the most suitable for the AP2 access client 1, i.e., where the load balancing group 1 is selected for the smallest load a AP2 an access from the client to the client.

其中,无线控制器3包括客户端表项建立模块31和负载均衡配置模块32,客户端表项建立模块31用于根据无线接入设备AP2上报的客户端信息建立包含客户端1与上报AP2对应关系的客户端表项,并统一保存;负载均衡配置模块32,用于在客户端1请求接入时,根据客户端表项建立模块31中保存的客户端表项,选择AP供所述客户端接入。 Wherein the wireless controller 3 comprises a client entry establishing module 31 and a load balancing configuration module 32, client module 31 entry for establishing wireless access device AP2 establish client information reported by the client 1 and comprising a corresponding reporting AP2 client relationship entry, saving and unity; load balancing configuration module 32, configured to, when a client requests access, establishing module 31 stored in the client the client entry table entry, for selecting said client AP the access terminal.

如图6所示,为本发明实施例一种动态维护客户端表项的流程图,该实施例提出了一种通过AP维护客户端表项的方法,通过在AP上设置老化定时器,如果在该老化定时超时前该AP未收到某个客户端新的探测请求报文,则通知无线控制器将该客户端和该AP对应的客户端表项删除,以及时更新客户端表项。 6, a flowchart of a dynamic maintain client entries embodiment of the present invention, this embodiment proposes a method of maintaining a client entry via AP, the AP provided by aging timer, if the aging timer expires before the AP does not receive a client request for a new probe packet, notifies the client entries are deleted and the client access controller and corresponding to the AP, and updates client table entries. 该实施例包括以下步骤:步骤S601:各个无线接入设备AP记录其覆盖范围内的客户端信息并上报。 This embodiment comprises the following steps: Step S601,: recording each radio access device client AP within its coverage and information report.

无线接入设备AP在当前的工作信道上侦听客户端发送的探测请求报文,该探测请求报文是802.11的协议报文,携带有客户端的基本信息(如该客户端的MAC地址),客户端通过该报文找到AP。 Listening AP wireless access device in the current working channel of the client sending the probe request message, the probe request packet is a 802.11 protocol packets, carrying basic information of the client (e.g., client's MAC address), the client by the end of the message to find the AP. 因此如果AP收到一个客户端的探测请求报文则说明该客户端在该AP的覆盖范围内,该AP根据收到的探测请求报文记录该客户端的信息及收到该探测请求报文的时间戳,并将上述信息上报给无线控制器。 Therefore, if a client of the AP receives the probe request packet indicates that the client within the coverage of the AP, the AP request message to the client's information and time of receipt of the probe request packet is recorded according to the received detection stamp, and to report this information to the controller.

步骤S602:无线接入设备AP在该上报AP上设置一个客户端表项,并为该客户端表项启动一个老化定时器。 Step S602: AP wireless access device provided in a client entry reporting the AP, and a timer for the aging client entries start.

步骤S603:无线控制器根据所有与其连接AP上报的客户端信息建立包含客户端与上报AP对应关系的客户端表项并统一保存。 Step S603: establishing a wireless controller client entry contains the client reports the AP and all the correspondence relationship according connected thereto AP information reported by the client and the unified storage.

无线控制器根据每个AP上报的客户端信息建立包含客户端与上报AP对应关系的客户端表项并统一保存,该客户端表项包括客户端信息和上报该客户端信息的AP标识,其中客户端信息和AP标识为唯一标识该客户端和该AP的ID,例如该客户端的MAC地址,AP的IP地址。 The establishment of the wireless controller for each AP reported by the client table entry contains information of the client and the client reports the AP save a correspondence between unity and the client includes a client entry information and reports the AP identification information to the client, wherein the client and AP identification information to uniquely identify the client and the AP ID, for example the MAC address of the client, IP address of the AP.

步骤S604:如果在客户端表项的老化定时器超时前,该AP未收到该客户端表项对应的客户端新的探测请求报文,则AP通知无线控制器将无线控制器上该客户端和该AP对应的客户端表项删除。 Step S604: If the timer expires before entry of the client, the client of the AP corresponding to the entry end of the new client does not receive the probe request packet, the AP notifies the radio controller on the client access controller the client-side and delete entries corresponding to the AP. 例如AP1在老化定时器超时前未收到客户端1新的探测请求报文,则该AP1将通知无线控制器将包含AP1和客户端1对应的客户端表项删除。 E.g. AP1 aging time before the client does not receive a new probe request message, the radio controller AP1 notifies the client comprising client AP1 and deletes the corresponding entry 1.

如果在客户端表项的老化定时器超时前,该AP未收到该客户端表项对应的客户端新的探测请求报文,则说明该客户端已不在该AP的覆盖范围内,或该客户端已关机下线。 If the client before the aging timer times out entries, the AP does not receive the client table entry corresponding to the new client probe request packet, it indicates that the client is out of range of the AP, or the The client has been shut off the assembly line. 因此应当及时更新在无线控制器中的该客户端的表项,将过期没用的包含有未收到新请求报文AP的客户端表项删除,这样进一步提高负载均衡调度的准确性。 Therefore, it should be up to date on the wireless controller in the entry of the client, will expire useless contains entries not received client request message to delete the new AP, thus further improving the accuracy of load balancing scheduling. 在包含有未收到新请求报文AP的客户端表项均被删除后,则说明该客户端已下线或关机,则应当将该客户端表项删除,等待下次该客户端重新发送请求报文后再为其创建对应的客户端表项。 After the new request is not received with AP message client entries are deleted, then the client is offline or shut down, the client should delete the entry, waiting for the next client resends request packet and then create corresponding client entries. 该实施例通过在AP上对客户端表项进行老化可以减少AP与无线控制器的报文通讯,提高无线控制器的运行能力。 By this embodiment, the client entries in aging on the AP can reduce packet AP and the wireless communication controller, the ability to improve the operation of the wireless controller.

如图7所示,为本发明实施例另一种动态维护客户端表项的流程图,该实施例提出了一种在无线控制器上设置老化计数器的维护方法,包括以下步骤:步骤S701:各个无线接入设备AP记录其覆盖范围内的客户端信息并上报。 As shown in FIG. 7 is a flowchart of another dynamic maintenance client entries embodiment of the invention, this embodiment proposes an arrangement of the aging counter in access controller maintenance method, comprising the following steps: Step S701,: AP records each radio access device within the coverage area of ​​the client-side information and reporting.

无线接入设备AP在当前的工作信道上侦听客户端发送的探测请求报文,该探测请求报文是802.11的协议报文,携带有客户端的基本信息(如该客户端的MAC地址),客户端通过该报文找到AP。 Listening AP wireless access device in the current working channel of the client sending the probe request message, the probe request packet is a 802.11 protocol packets, carrying basic information of the client (e.g., client's MAC address), the client by the end of the message to find the AP. 因此如果AP收到一个客户端的探测请求报文则说明该客户端在该AP的覆盖范围内,该AP根据收到的探测请求报文记录该客户端的信息及收到该探测请求报文的时间戳,并将上述信息上报给无线控制器。 Therefore, if a client of the AP receives the probe request packet indicates that the client within the coverage of the AP, the AP request message to the client's information and time of receipt of the probe request packet is recorded according to the received detection stamp, and to report this information to the controller.

步骤S702:无线控制器根据所有与其连接AP上报的客户端信息建立包含客户端与上报AP对应关系的客户端表项并统一保存。 Step S702: establishing a wireless controller client entry contains the client reports the AP and all the correspondence relationship according connected thereto AP information reported by the client and the unified storage.

无线控制器根据每个AP上报的客户端信息建立包含客户端与上报AP对应关系的客户端表项并统一保存,该客户端表项包括客户端信息和上报该客户端信息的AP标识,其中客户端信息和AP标识为唯一标识该客户端和该AP的ID,例如该客户端的MAC地址,AP的IP地址。 The establishment of the wireless controller for each AP reported by the client table entry contains information of the client and the client reports the AP save a correspondence between unity and the client includes a client entry information and reports the AP identification information to the client, wherein the client and AP identification information to uniquely identify the client and the AP ID, for example the MAC address of the client, IP address of the AP.

步骤S703:无线控制器针对每个客户端表项都启动一个老化定时器。 Step S703: the wireless controller for each client entry starts a timer aging.

步骤S704:如果在客户端表项的老化定时器超时前,该客户端表项未被重新建立,则将该客户端表项删除。 Step S704: If the aging timer before the entry of the client timeout, the client entry has not been re-established, the client entry is deleted.

老化定时器超时后没有重新建立该客户端表项说明该客户端已不在上报该客户端信息的AP的覆盖范围内,或者该客户端已关机下线。 No re-established after the timer expires the client entry within the coverage of the described client has not reported to the AP information of the client, the client is turned off or offline. 因为如果该客户端不在上报该客户端信息的AP的覆盖范围内或者关机下线,则该客户端就不会向AP发送探测请求报文,无线控制器也就不会根据AP侦听到的探测请求报文重新建立该客户端表项。 Since the coverage of the client if the client does not report the information of the AP or shut off the assembly line, the client will not request packet to the AP sends a probe, the controller will not listen to the radio in accordance with the AP a probe request to re-establish the client entries.

如果在定时器还未超时前,无线控制器重新建立了该客户端表项即说明该客户端还在上报该客户端信息的AP的覆盖范围内,则需要重启定时器。 If before the timer has not timed out, the wireless controller to re-establish the client entry that is explained within the coverage area of ​​the client also reports the AP client information, you need to restart the timer. 因此通过本发明实施例可以及时更新客户端表项,将过期没用的客户端表项删除,进一步提高了负载均衡调度的准确性。 Thus embodiments can update the client table entry will expire useless client entry is deleted, thereby improving the accuracy of the load balancing by scheduling the present invention.

通过本发明实施例实现了用户不需要手工进行配置,而由本发明实施例根据负载情况选择AP供客户端接入,提高了负载均衡调度的准确性,避免了用户经历过多的接入失败尝试。 Embodiment enables the user does not need to be manually configured, the embodiment of the present invention for clients to access the selected AP according to the load, improving the accuracy of scheduling load balancing, to avoid excessive failed attempts to access the user experience by the present invention . 并且通过对客户端表项的动态维护,可以及时更新客户端表项,进一步提高了负载均衡调度的准确性。 And by the maintenance of dynamic client entries, you can update the client entry, to further improve the accuracy of load balancing scheduling.
