宽带无线网络中提供差异化服务的方法及装置Method and device for providing differentiated services in broadband wireless network

技术领域technical field

本发明涉及无线通信技术，尤其涉及一种宽带无线网络中提供差异化服务的方法及装置。The invention relates to wireless communication technology, in particular to a method and device for providing differentiated services in a broadband wireless network.

背景技术Background technique

WLAN（Wireless Local Area Networks，无线局域网络）作为一种高速的宽带无线接入被引入到电信运营系统中，图1为现有无线局域网络的架构示意图。现有WLAN网络中包括STA（Station，站）、AP（Access Point，访问接入点）、AC（Access Controller，无线接入控制器）、交换机、光网络传输设备、BRAS（Broadband Remote Access Server，宽带远程接入服务器）、Portal服务器、AAA（Authentication、Authorization、Accounting，认证、授权和统计）服务器等。WLAN在电信运营系统中的部署大都利用有线宽带的资源来接入业务系统。WLAN (Wireless Local Area Networks, wireless local area network) is introduced into the telecom operation system as a high-speed broadband wireless access. Figure 1 is a schematic diagram of the existing wireless local area network architecture. The existing WLAN network includes STA (Station, station), AP (Access Point, access point), AC (Access Controller, wireless access controller), switch, optical network transmission equipment, BRAS (Broadband Remote Access Server, Broadband remote access server), Portal server, AAA (Authentication, Authorization, Accounting, authentication, authorization and statistics) server, etc. Most of the deployment of WLAN in the telecom operation system uses wired broadband resources to access the service system.

如图1所示，用户在WLAN中访问业务的过程如下：WLAN用户与AP建立关联，具体是通过AC的控制实现用户与AP的关联，如图1中虚线路径所示，AC作为AP的控制器，能够控制并管理与其连接的AP，如功率的控制等。客户端与AP关联后，通过AP向BRAS发起DHCP（Dynamic HostConfiguration Protocol，动态主机设置协议）报文，BRAS收到客户端的DHCP报文后，给客户端分配IP地址。当客户端发起HTTP（Hypertext TransportProtocol，超文本传送协议）报文时，BRAS截获并将其重定向到Portal服务器，从而实现客户端通过Portal服务器的实现接入控制的业务，如图1中点划线路径所示。As shown in Figure 1, the process of users accessing services in WLAN is as follows: WLAN users establish an association with the AP, specifically through the control of the AC to realize the association between the user and the AP, as shown in the dashed path in Figure 1, the AC acts as the control of the AP It can control and manage the APs connected to it, such as power control, etc. After the client is associated with the AP, it sends a DHCP (Dynamic Host Configuration Protocol) message to the BRAS through the AP, and the BRAS assigns an IP address to the client after receiving the DHCP message from the client. When the client initiates an HTTP (Hypertext Transport Protocol, hypertext transfer protocol) message, the BRAS intercepts it and redirects it to the Portal server, thereby realizing the client's access control service through the Portal server, as shown in Figure 1. The line path is shown.

通过AP以无线方式接入网络的用户之间存在差异化服务的需求，比如有些用户需要加密服务，有些用户需要较大的带宽、或者较高的优先级等。在传统的固定宽带接入网络中，用户设备接入网络AP的位置相对固定，各AP与其IP地址之间的对应关系基本保持不变，这些为不同AP提供的差异化服务一般是通过区分用户的IP地址来实现的。而在WLAN应用中，用户设备随时会发生移动，固定IP地址已无法实现，IP地址通常是动态分配给不同的AP，因此，不能继续使用固网中根据IP地址为不同AP提供差异化服务的方法。Users accessing the network wirelessly through APs have differentiated service requirements. For example, some users require encryption services, while others require larger bandwidth or higher priority. In the traditional fixed broadband access network, the location of the user equipment to access the network AP is relatively fixed, and the corresponding relationship between each AP and its IP address remains basically unchanged. These differentiated services for different APs are generally distinguished by IP address to achieve. In WLAN applications, user equipment may move at any time, and fixed IP addresses are no longer available. IP addresses are usually dynamically assigned to different APs. Therefore, the fixed network that provides differentiated services for different APs based on IP addresses cannot continue. method.

当前WLAN在差异化服务开展过程中大都采用VLAN（Virtual Local AreaNetwork，虚拟局域网）配置的方法，对用户区域或业务进行区分，从而BRAS将相关VLAN配置信息传递给业务系统，如Portal、AAA等，从而实现差异化的业务。At present, WLAN mostly adopts VLAN (Virtual Local Area Network, virtual local area network) configuration method in the process of developing differentiated services to distinguish user areas or services, so that BRAS transmits relevant VLAN configuration information to service systems, such as Portal, AAA, etc. In order to achieve differentiated business.

但是，现有的WLAN网络架构中，由于WLAN的接入控制设备BRAS只能捕获用户信息（如用户名、密码），而对用户的接入信息无法获取，如用户通过哪个AP接入。因此对WLAN实现差异化的业务较易受限制。当前基于VLAN配置的方法实现WLAN差异化服务，其受到VLAN规划的限制（当前已升级到二级VLAN，但VLAN数有限），对于业务的开展仍然受到较多限制，难以灵活开展。However, in the existing WLAN network architecture, the WLAN access control device BRAS can only capture user information (such as user name and password), but cannot obtain user access information, such as which AP the user accesses through. Therefore, differentiated services for WLAN are more likely to be restricted. The current method based on VLAN configuration to implement WLAN differentiated services is limited by VLAN planning (it has been upgraded to a second-level VLAN, but the number of VLANs is limited), and there are still many restrictions on business development, making it difficult to develop flexibly.

另外，当前有部分解决方案通过在用户接入时，通过DHCP的Option 82中携带AP标识的方法，将AP标识上报到BRAS，从而报告给业务系统。然而在用户接入时的上报方法对于用户发生移动，形成二层切换后，即用户IP地址不变但是AP发生变化，由于不再有DHCP过程，因此不能再通过上述方法上报AP标识，造成用户信息失效等问题。In addition, some current solutions report the AP ID to the BRAS by carrying the AP ID in Option 82 of DHCP when the user accesses, and then report it to the service system. However, the reporting method when the user accesses is that the user moves, and after a Layer 2 handover is formed, that is, the user IP address remains unchanged but the AP changes. Since there is no longer a DHCP process, the AP identity cannot be reported through the above method, resulting in user Information failure and other issues.

具体实施方式Detailed ways

下面结合附图与实施例对本发明做进一步的描述。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

实施例一Embodiment one

图2为本发明实施例一提供的宽带无线网络中提供差异化服务的方法的流程图，图3为本发明实施例提供的宽带无线网络中提供差异化服务的方法所适用的无线局域网络的架构示意图。在现有的无线局域网络中，网关只能捕获用户信息（如用户名、密码），而对用户的接入信息无法获取，如用户通过哪个AP接入。本实施例通过在无线接入控制器与网关之间建立二层隧道，实现无线接入控制器与网关之间的信息互通，则网关能够获取用户的接入信息。Fig. 2 is a flowchart of a method for providing differentiated services in a broadband wireless network according to Embodiment 1 of the present invention, and Fig. 3 is a flowchart of a wireless local area network to which the method for providing differentiated services in a broadband wireless network according to an embodiment of the present invention is applicable Architecture diagram. In the existing wireless local area network, the gateway can only capture user information (such as user name and password), but cannot obtain access information of the user, such as which AP the user accesses through. In this embodiment, a layer-2 tunnel is established between the wireless access controller and the gateway to realize information exchange between the wireless access controller and the gateway, and the gateway can obtain user access information.

本实施例的宽带无线网络中提供差异化服务的方法具体由网关执行，与无线网络系统中其他网元相配合执行。该方法包括以下步骤：The method for providing differentiated services in the broadband wireless network of this embodiment is specifically executed by the gateway, and is executed in cooperation with other network elements in the wireless network system. The method includes the following steps:

步骤100：网关通过与无线接入控制器之间的二层隧道，获取客户端接入无线网络的访问接入点的接入信息。Step 100: the gateway obtains the access information of the access point through which the client accesses the wireless network through a layer-2 tunnel with the wireless access controller.

客户端与AP关联成功后，该AP将向其所连接的AC发送该AP的标识、IP地址和/或物理地址，以及与该AP关联的客户端的物理地址。该AC收到上述信息后，将通过其与网关之间的二层隧道发送客户端的上述接入信息至网关。After the client is successfully associated with the AP, the AP will send the AP's ID, IP address and/or physical address, and the physical address of the client associated with the AP to the AC it is connected to. After receiving the above information, the AC will send the above access information of the client to the gateway through the Layer 2 tunnel between it and the gateway.

步骤110：网关获取为所述客户端分配的IP地址。Step 110: the gateway acquires the IP address assigned to the client.

客户端通过AP向网关发出IP地址分配请求，网关通过识别该客户端的物理地址并根据DHCP协议向该客户端分配IP地址，同时也获取了该客户端的IP地址。The client sends an IP address assignment request to the gateway through the AP, and the gateway identifies the client's physical address and assigns an IP address to the client according to the DHCP protocol, and also obtains the client's IP address.

步骤120：网关获取所述客户端的用户信息。Step 120: the gateway obtains the user information of the client.

用户通过Portal服务器进行认证，当Portal服务器将用户认证信息在Radius（Remote Authentication Dial In User Service，远程用户拨号认证系统）侧完成认证后，Portal服务器会向Radius发起连接请求（Connect Request，该消息为Portal与Radius的私有协议），此时将触发Radius与网关之间的会话更新以及计费过程，Radius将给网关返回的授权变更信息（Change ofAuthorization，简称CoA）。该CoA信息中包含了用户的IP地址、用户名等信息，网关从该CoA消息中获取用户的IP地址、用户名等用户信息。The user is authenticated by the Portal server. When the Portal server completes the authentication of the user authentication information on the Radius (Remote Authentication Dial In User Service, remote user dial-in authentication system), the Portal server will initiate a connection request (Connect Request) to the Radius. The message is Portal and Radius private protocol), at this time, it will trigger the session update and billing process between Radius and the gateway, and Radius will return the authorization change information (Change of Authorization, CoA for short) to the gateway. The CoA information includes information such as the user's IP address and user name, and the gateway obtains user information such as the user's IP address and user name from the CoA message.

步骤130：网关建立所述接入信息、IP地址和用户信息之间的关联关系。Step 130: The gateway establishes the association relationship among the access information, IP address and user information.

网关存储客户端的物理地址、IP地址，客户端关联的访问接入点的标识、IP地址和/或物理地址，以及用户名的关联关系，以便根据不同访问接入点，进行差异化的业务操作。The gateway stores the physical address and IP address of the client, the identification, IP address and/or physical address of the access point associated with the client, and the association relationship of the user name, so as to perform differentiated business operations according to different access points .

步骤140：网关根据所述关联关系，为所述客户端提供与接入信息对应的业务服务。Step 140: The gateway provides the client with the service corresponding to the access information according to the association relationship.

无线网络业务系统中的各类业务服务器在为各客户端提供业务服务时，可从网关获取客户端的物理地址、IP地址，客户端关联的访问接入点的标识、IP地址和/或物理地址，以及用户名的关联对应关系，则无线网络业务系统则可以根据预先配置的访问接入点与业务类型的对应关系，为接入不同访问接入点的客户端通过网关提供差异化服务。无线网络业务系统包括无线网络中各类业务服务器，例如视频服务器、短信服务器等，还包括Portal服务器和Radius。When various business servers in the wireless network business system provide business services for each client, they can obtain the physical address and IP address of the client from the gateway, and the identification, IP address and/or physical address of the access point associated with the client , and the association and correspondence of user names, the wireless network service system can provide differentiated services for clients accessing different access points through the gateway according to the pre-configured correspondence between access points and service types. The wireless network service system includes various service servers in the wireless network, such as video server, short message server, etc., and also includes Portal server and Radius.

由上述技术方案可知，WLAN网关通过与无线接入控制器之间的二层隧道，从无线接入控制器获取用户的关联接入信息，WLAN业务系统进行业务开展时则可通过网关获取用户的关联接入信息，从而对接入不同访问接入点的客户端进行差异化的业务处理。It can be seen from the above technical solution that the WLAN gateway obtains the user's associated access information from the wireless access controller through the layer 2 tunnel between the WLAN gateway and the wireless access controller, and the WLAN service system can obtain the user's associated access information through the gateway when performing services. Associate access information to perform differentiated business processing on clients accessing different access points.

实施例二Embodiment two

本实施例在上述实施例的基础上，步骤100通过与无线接入控制器之间的二层隧道，获取客户端接入网络的访问接入点的接入信息具体为以下步骤：In this embodiment, on the basis of the above-mentioned embodiments,step 100 obtains the access information of the access point for the client to access the network through the Layer 2 tunnel with the wireless access controller, specifically the following steps:

步骤101：当无线接入控制器接收到客户端向访问接入点发起的关联请求时，网关通过与所述无线接入控制器之间的二层隧道，从所述无线接入控制器处获取所述访问接入点的标识、IP地址和/或物理地址，以及关联所述访问接入点的客户端的物理地址，作为所述接入信息。Step 101: When the wireless access controller receives the association request initiated by the client to the access point, the gateway communicates with the wireless access controller through a layer 2 tunnel with the wireless access controller Obtain the identifier, IP address and/or physical address of the access point, and the physical address of the client associated with the access point as the access information.

由于访问接入点与无线接入控制器之间通过CAPWAP（Control AndProvisioning of Wireless Access Points Protocol，无线接入点的控制与配置）协议实现信息交互，所以当客户端关联访问接入点后，无线接入控制器可通过CAPWAP协议获取客户端的物理地址以及该客户端所关联的访问接入点的标识、IP地址和/或物理地址，再将上述信息作为接入信息通过与网关之间的二层隧道发送至网关。Since the access point and the wireless access controller realize information interaction through the CAPWAP (Control AndProvisioning of Wireless Access Points Protocol, control and configuration of wireless access points), after the client associates with the access point, the wireless The access controller can obtain the physical address of the client and the identifier, IP address and/or physical address of the access point associated with the client through the CAPWAP protocol, and then use the above information as access information through the two-way communication with the gateway. layer tunnel to the gateway.

由上述技术方案可知，WLAN网关通过与无线接入控制器之间的二层隧道，从无线接入控制器获取客户端的接入信息，以便后续针对接入不同访问接入点的客户端进行差异化的业务处理。It can be seen from the above technical solution that the WLAN gateway obtains the access information of the client from the wireless access controller through the layer 2 tunnel between the WLAN gateway and the wireless access controller, so as to subsequently differentiate between the clients accessing different access points. business processing.

实施例三Embodiment Three

图4为本发明实施例三提供的宽带无线网络中提供差异化服务的方法的流程图，本实施例的方法具体由网关执行，本实施例在上述实施例的基础上，进一步的该宽带无线网络中提供差异化服务的方法还可以包括如下步骤：Fig. 4 is a flowchart of a method for providing differentiated services in a broadband wireless network provided by Embodiment 3 of the present invention. The method of this embodiment is specifically executed by a gateway. The method for providing differentiated services in the network may also include the following steps:

步骤A：当无线接入控制器接收到客户端位置变更请求时，网关通过与所述无线接入控制器的二层隧道，从所述无线接入控制器处获取所述客户端的新的访问接入点的标识、IP地址和/或物理地址，并根据所述客户端的物理地址，更新所述客户端的接入信息。Step A: When the wireless access controller receives the location change request of the client, the gateway obtains the new access information of the client from the wireless access controller through the layer 2 tunnel with the wireless access controller The identifier, IP address and/or physical address of the access point, and update the access information of the client according to the physical address of the client.

若客户端发生移动，触发二层切换时，即客户端的IP地址的不变，但是该客户端所接入的访问接入点已经改变时，如果不及时更新该客户端的接入信息，则针对接入不同访问接入点的客户端进行差异化的业务处理将无法正常进行。本实施例中，当无线接入控制器根据CAPWAP协议收到客户端位置变更请求，该无线接入控制器将为该客户端重新关联访问接入点，从而获取该客户端所关联的新的访问接入点的标识、IP地址和/或物理地址，并将上述信息通过与网关之间的二层隧道发送至网关。网关则根据该客户端的物理地址，更新该客户端的接入信息，即更新该客户端物理地址关联对应的访问接入点的标识、IP地址和/或物理地址，以便进行差异化业务操作时使用。If the client moves and a Layer 2 handover is triggered, that is, the IP address of the client remains unchanged, but the access point that the client accesses has changed, if the access information of the client is not updated in time, the Clients connected to different access points will not be able to perform differentiated business processing. In this embodiment, when the wireless access controller receives the client location change request according to the CAPWAP protocol, the wireless access controller will re-associate the access point for the client, so as to obtain the new location associated with the client. Access the identification, IP address and/or physical address of the access point, and send the above information to the gateway through the layer 2 tunnel with the gateway. The gateway updates the access information of the client according to the physical address of the client, that is, updates the identification, IP address and/or physical address of the access point associated with the physical address of the client, so that it can be used for differentiated business operations. .

由上述技术方案可知，当客户端发生移动触发二层切换时，客户端的IP地址保持不变，但是该客户端所接入的访问接入点已经变化，通过无线接入控制器向网关发送该客户端当前所接入的访问接入点的标识、IP地址和/或物理地址，网关则更新该客户端的接入信息，以保证WLAN业务系统进行基于访问接入点的差异化服务所依据的用户接入信息的有效性。It can be known from the above technical solution that when the client moves and triggers a Layer 2 handover, the IP address of the client remains unchanged, but the access point accessed by the client has changed, and the wireless access controller sends the IP address to the gateway. The identifier, IP address and/or physical address of the access point currently accessed by the client, and the gateway updates the access information of the client to ensure that the WLAN service system performs differentiated services based on the access point.
