本发明涉及移动通信领域，尤其涉及一种WAP(无线访问协议)网关及其业务处理方法和WAP代理服务器。The invention relates to the field of mobile communication, in particular to a WAP (Wireless Access Protocol) gateway, a service processing method thereof, and a WAP proxy server.
背景技术Background technique
WAP(Wireless Access Protocol，无线访问协议)网关是移动终端接入互联网的重要系统之一，WAP网关在移动数据业务的处理流程中起到了承载和控制的作用，实现编解码以及协议转换、用户代理、以及MSISDN(Mobile StationInternational ISDN Number，移动台国际ISDN号码；ISDN：Integrated ServicesDigital Network，综合业务数字网)、终端类型等用户信息的前转控制功能，提供对基于WAP1.X协议和WAP2.0协议移动终端的业务支持。随着无线带宽的增加、移动终端处理能力的增强和无线应用的丰富，越来越多的移动终端基于WAP2.0协议通过WAP网关进行业务访问。WAP网关系统架构如图1所示，移动终端通过WAP网关接入互联网，实现对SP(Service Provider，服务提供商)的访问。WAP网关可以获取移动终端的MSISDN、终端类型等用户信息，通过设置WAP网关可以选择将移动终端的用户信息传送给可靠的SP，同时禁止访问不可靠的SP，以保证用户的利益。WAP (Wireless Access Protocol, wireless access protocol) gateway is one of the important systems for mobile terminals to access the Internet. WAP gateway plays the role of bearer and control in the processing flow of mobile data services, realizing codec and protocol conversion, user agent , and MSISDN (Mobile Station International ISDN Number, mobile station international ISDN number; ISDN: Integrated Services Digital Network, Integrated Services Digital Network), terminal type and other user information forwarding control functions, providing WAP1.X protocol and WAP2.0 protocol Business support for mobile terminals. With the increase of wireless bandwidth, enhancement of mobile terminal processing capability and enrichment of wireless applications, more and more mobile terminals access services through WAP gateway based on WAP2.0 protocol. The WAP gateway system architecture is shown in Figure 1. The mobile terminal accesses the Internet through the WAP gateway to access the SP (Service Provider, service provider). The WAP gateway can obtain user information such as MSISDN and terminal type of the mobile terminal. By setting the WAP gateway, you can choose to transmit the user information of the mobile terminal to a reliable SP, and prohibit access to unreliable SPs to ensure the interests of users.
如图2所示，WAP网关主要由路由器、WAP代理服务器、负载均衡设备、防火墙等网络设备组成，实际组网中普遍采用负载均衡设备结合由多台WAP代理服务器组成的服务器集群的系统架构实现大容量需求。现有技术中，WAP网关的业务处理流程包括：As shown in Figure 2, the WAP gateway is mainly composed of routers, WAP proxy servers, load balancing devices, firewalls and other network devices. In actual networking, the system architecture of load balancing devices combined with server clusters composed of multiple WAP proxy servers is generally used. Large capacity needs. In the prior art, the business processing flow of the WAP gateway includes:
步骤1、移动终端发起业务访问请求，经由GGSN(Gateway GPRS SupportNode，网关GPRS支持节点；GPRS：General Packet Radio Service，通用分组无线业务)发送到WAP网关的路由器，再由路由器发送给负载均衡设备；Step 1. The mobile terminal initiates a service access request, which is sent to the router of the WAP gateway via GGSN (Gateway GPRS SupportNode, gateway GPRS support node; GPRS: General Packet Radio Service, general packet radio service), and then sent to the load balancing device by the router;
路由器基于GRE(Generic Routing Encapsulation，通用路由封装)协议，GRE协议定义了使用一种网络层协议封装另一种网络层协议的方法。The router is based on the GRE (Generic Routing Encapsulation, general routing encapsulation) protocol. The GRE protocol defines the method of using one network layer protocol to encapsulate another network layer protocol.
步骤2、负载均衡设备从服务器集群中选取为移动终端提供服务的WAP代理服务器，并将业务访问请求发送给选取出的WAP代理服务器。Step 2: The load balancing device selects a WAP proxy server that provides services for the mobile terminal from the server cluster, and sends the service access request to the selected WAP proxy server.
步骤3、WAP代理服务器对业务访问请求进行编解码和协议转换，根据前转控制的要求，判断业务访问请求对应的URL(Uniform Resource Locator，统一资源定位符)是否在禁止访问的黑名单中、是否在需要前转用户信息的白名单中，如果不在黑名单中，将由业务访问请求转换得到的路由请求发送给防火墙，如果在白名单中，还需要进行HTTP(Hyper Text Transport Protocol，超级文本传送协议)Header信息的重构，在HTTP Header信息中增加需要前转的用户信息(MSISDN、终端类型等)。Step 3, WAP proxy server codec and protocol conversion are carried out to service access request, according to the requirement of forwarding control, judge whether the URL (Uniform Resource Locator, Uniform Resource Locator) corresponding to service access request is in the blacklist of prohibiting access, Whether it is in the white list that needs to forward user information, if it is not in the black list, send the routing request converted from the service access request to the firewall, if it is in the white list, HTTP (Hyper Text Transport Protocol, hypertext transmission) is also required protocol) Header information reconstruction, adding user information (MSISDN, terminal type, etc.) that needs to be forwarded to the HTTP Header information.
步骤4、防火墙将WAP代理服务器的路由请求前转给SP的业务服务器，业务服务器返回的响应数据再按照发送路径返回给移动终端；Step 4, the firewall forwards the routing request of the WAP proxy server to the service server of the SP, and the response data returned by the service server is returned to the mobile terminal according to the sending path;
防火墙接收WAP代理服务器的路由请求，进行NAT(Network AddressTranslate，网络地址转换)，通过互联网访问服务提供商SP的业务服务器。The firewall receives the routing request of the WAP proxy server, performs NAT (Network Address Translate, Network Address Translation), and accesses the service server of the service provider SP through the Internet.
随着无线应用的快速发展，WAP网关承载的业务量和业务类型越来越多，不同类型业务对WAP网关的处理逻辑要求是不同的；服务提供商也越来越多，各服务提供商提供服务的稳定性和能力也是不同的。现有技术中WAP网关的业务处理方案，对不同类型业务统一处理并采用相同的业务处理机制，随着对WAP代理服务器的处理逻辑要求日趋复杂，使得网络设备的处理能力成为系统瓶颈，部分服务提供商出现故障时用户的频繁连接风暴会消耗大量的WAP网关资源，严重影响其它业务的使用，导致WAP网关的处理能力较差，WAP网关提供服务的稳定性较低。With the rapid development of wireless applications, WAP gateways carry more and more business volumes and business types, and different types of business have different processing logic requirements for WAP gateways; there are also more and more service providers, and each service provider provides The stability and capacity of the service is also different. The business processing scheme of the WAP gateway in the prior art uniformly processes different types of business and adopts the same business processing mechanism. As the processing logic requirements for the WAP proxy server become increasingly complex, the processing capacity of the network equipment becomes a system bottleneck, and some services When the provider breaks down, frequent user connection storms will consume a large amount of WAP gateway resources, seriously affecting the use of other services, resulting in poor processing capabilities of the WAP gateway and low stability of services provided by the WAP gateway.

具体实施方式Detailed ways
本发明实施例提供了一种WAP网关及其业务处理方法，用以实现对不同类型业务的差异化处理，从而避免不同类型业务之间的相互影响，提升WAP网关的处理能力，提高WAP网关提供服务的稳定性。The embodiment of the present invention provides a WAP gateway and a service processing method thereof, which are used to implement differentiated processing of different types of services, thereby avoiding the mutual influence between different types of services, improving the processing capability of the WAP gateway, and improving the WAP gateway to provide Stability of service.
根据WAP网关的功能和现网中承载业务的特点，针对可以缓存的图片(GIF/PNG/JPEG)、文本(TXT)等，移动终端发起的业务访问请求占比达到40％；即时通信等长时间在线业务的业务访问请求的占比较高，但稳定性差、业务时延较大，同时该类业务不需要传送附加的用户信息。基于以上分析，本发明实施例提出如下改进：由WAP代理服务器组成的服务器集群中，各WAP代理服务器在软件部署时按照提供服务的业务类型划分为若干服务器分组，部分服务器分组为缓存业务提供服务，部分服务器分组为即时通信业务提供服务，部分服务器分组为缓存业务和即时通信业务之外的其它业务提供服务，本申请文件中将缓存业务和即时通信业务之外的其它业务统称为普通业务。负载均衡设备针对每一个接收到的业务访问请求，首先确定业务类型，根据确定出的业务类型将业务访问请求分流到对应的服务器分组，各服务器分组中的WAP网关代理服务器，根据提供服务的业务类型，对接收到的业务访问请求执行相应的业务处理从而避免不同类型业务之间的相互影响，根据业务类型的特点，可以相应的简化业务处理逻辑，从而提升WAP网关的处理能力，提高WAP网关提供服务的稳定性。According to the functions of the WAP gateway and the characteristics of the services carried in the existing network, for images (GIF/PNG/JPEG) and text (TXT) that can be cached, the proportion of service access requests initiated by mobile terminals reaches 40%; Time-online services account for a relatively high proportion of service access requests, but their stability is poor and their service delays are large. At the same time, this type of service does not need to transmit additional user information. Based on the above analysis, the embodiment of the present invention proposes the following improvements: in a server cluster composed of WAP proxy servers, each WAP proxy server is divided into several server groups according to the type of service provided during software deployment, and some server groups provide services for caching services , some server groups provide services for instant messaging services, and some server groups provide services for caching services and services other than instant messaging services. In this application document, services other than caching services and instant messaging services are collectively referred to as ordinary services. For each service access request received, the load balancing device first determines the service type, and distributes the service access request to the corresponding server group according to the determined service type. The WAP gateway proxy server in each server group, according to the service provided business According to the characteristics of the business type, the business processing logic can be simplified accordingly, so as to improve the processing capacity of the WAP gateway and improve the WAP gateway Provide stability of service.
本发明实施例无需对WAP网关中的路由器、防火墙等网络设备进行任何改动，只需对WAP网关的负载均衡设备以及服务器集群的部署、以及部分WAP代理服务器的处理逻辑进行改进即可，即对服务器集群按照提供服务的业务类型进行分组，负载均衡设备需要能实现对业务访问请求的深度内容解析确定业务类型，并将业务访问请求分流到对应的服务器分组，同时为缓存业务和即时通信业务提供服务的WAP代理服务器的处理逻辑进行简化。Embodiments of the present invention do not need to make any changes to network devices such as routers and firewalls in the WAP gateway, and only need to improve the deployment of the load balancing device and the server cluster of the WAP gateway, as well as the processing logic of some WAP proxy servers, that is, to Server clusters are grouped according to the types of services they provide. The load balancing device needs to be able to implement in-depth content analysis of service access requests to determine the service type, and distribute service access requests to the corresponding server groups. At the same time, it provides cache services and instant messaging services. The processing logic of the service's WAP proxy server is simplified.
如图3所示，WAP网关包括路由器、防火墙等网络设备，与现有技术中完全一致；还包括负载均衡设备和由多台WAP代理服务器组成的服务器集群，服务器集群中的各WAP代理服务器按照提供服务的业务类型划分为若干服务器分组，其中：As shown in Figure 3, the WAP gateway includes network devices such as routers and firewalls, which are completely consistent with the prior art; The business types that provide services are divided into several server groups, among which:
负载均衡设备，用于接收到移动终端发起的携带标识信息的业务访问请求时，根据标识信息确定该业务访问请求的业务类型，从为该业务类型提供服务的服务器分组中选取WAP代理服务器，并将该业务访问请求转发给选取出的WAP代理服务器；The load balancing device is configured to, when receiving a service access request carrying identification information initiated by a mobile terminal, determine the service type of the service access request according to the identification information, select a WAP proxy server from the group of servers providing services for the service type, and Forward the service access request to the selected WAP proxy server;
具体实施中，负载均衡设备从为该业务类型提供服务的服务器分组中，可以选取负载量最小的WAP代理服务器，或者，以轮询方式选取WAP代理服务器。In a specific implementation, the load balancing device may select the WAP proxy server with the smallest load from the group of servers providing services for the service type, or select the WAP proxy server in a polling manner.
WAP代理服务器，用于基于提供服务的业务类型，对接收到的业务访问请求执行相应的业务处理。The WAP proxy server is configured to perform corresponding service processing on the received service access request based on the service type provided.
业务访问请求中携带内容类型(Content Type)字段和地址信息子段，负载均衡设备基于深度内容解析，可以获取业务访问请求中携带的内容类型(Content Type)和地址信息，从而基于内容类型和地址信息确定业务访问请求的业务类型。The service access request carries the content type (Content Type) field and the address information subsection. Based on the in-depth content analysis, the load balancing device can obtain the content type (Content Type) and address information carried in the service access request, so that based on the content type and address Information identifying the business type of the business access request.
具体实施中，如果业务访问请求中携带的内容类型为文本或者图片，即Content Type字段的内容为TXT、GIF、PNG、JPEG等，则确定业务访问请求的业务类型为缓存业务；如果业务访问请求中携带的地址信息为即时通信SP的地址，即地址信息字段的内容为即时通信服务提供商的地址，则确定业务访问请求的业务类型为即时通信业务；否则，确定业务访问请求的业务类型为普通业务。In specific implementation, if the content type carried in the service access request is text or pictures, that is, the content of the Content Type field is TXT, GIF, PNG, JPEG, etc., then it is determined that the service type of the service access request is a cache service; if the service access request The address information carried in is the address of the instant messaging SP, that is, the content of the address information field is the address of the instant messaging service provider, then it is determined that the service type of the service access request is an instant messaging service; otherwise, it is determined that the service type of the service access request is Ordinary business.
需要说明的是，即时通信业务的业务访问请求中内容类型字段一般为空，因此不会出现“内容类型为文本或者图片、且地址信息为即时通信SP的地址”的情况，也就是说根据业务访问请求中携带的内容类型和地址信息，能够唯一确定业务访问请求的业务类型。It should be noted that the content type field in the service access request of the instant messaging service is generally empty, so the situation that "the content type is text or picture, and the address information is the address of the instant messaging SP" will not occur, that is to say, according to the service The content type and address information carried in the access request can uniquely determine the service type of the service access request.
本发明实施例提供的WAP网关，服务器集群中的各WAP代理服务器按照提供服务的业务类型划分为若干服务器分组，负载均衡设备接收到业务访问请求时，首先基于深度内容解析确定出业务访问请求的业务类型，在此基础上从业务类型对应的服务器分组中选取WAP代理服务器，选取出的WAP代理服务器基于提供服务的业务类型，对接收到的业务访问请求执行相应的业务处理。本发明实施例提供的WAP网关实现了对不同类型业务的差异化处理，从而避免了不同类型业务之间的相互影响，提升WAP网关的处理能力，提高WAP网关提供服务的稳定性。In the WAP gateway provided by the embodiment of the present invention, each WAP proxy server in the server cluster is divided into several server groups according to the type of service provided. When the load balancing device receives a service access request, it first determines the service access request based on deep content analysis. Business type, based on which WAP proxy server is selected from the server group corresponding to the business type, and the selected WAP proxy server performs corresponding business processing on the received business access request based on the business type of the service provided. The WAP gateway provided by the embodiment of the present invention implements differentiated processing of different types of services, thereby avoiding mutual influence between different types of services, improving the processing capability of the WAP gateway, and improving the stability of services provided by the WAP gateway.

具体实施中，处理单元502，还用于如果没有接收到业务服务器返回的响应数据，向业务服务器再次发送路由请求，直至接收到业务服务器返回的响应数据或者路由请求的发送次数超过连接数门限值。In specific implementation, the
基于同一技术构思，本发明实施例提供了一种WAP网关的业务处理方法，该方法的实施基于上述改进后的WAP网关，如图6所示，包括：Based on the same technical idea, the embodiment of the present invention provides a service processing method of a WAP gateway, the implementation of the method is based on the above improved WAP gateway, as shown in Figure 6, including:
S601、负载均衡设备接收到移动终端发起的携带标识信息的业务访问请求时，根据标识信息确定该业务访问请求的业务类型；S601. When the load balancing device receives a service access request carrying identification information initiated by a mobile terminal, determine the service type of the service access request according to the identification information;
S602、负载均衡设备从为该业务类型提供服务的服务器分组中选取WAP代理服务器，并将该业务访问请求转发给选取出的WAP代理服务器；S602. The load balancing device selects a WAP proxy server from the group of servers providing services for the service type, and forwards the service access request to the selected WAP proxy server;
S603、该WAP代理服务器基于提供服务的业务类型，对接收到的业务访问请求执行相应的业务处理。S603. The WAP proxy server performs corresponding service processing on the received service access request based on the service type provided.
具体实施中，标识信息包括内容类型和地址信息，地址信息可以采用URL、IP地址等，业务类型划分为缓存业务、即时通信业务和普通业务三种，如果业务访问请求中携带的内容类型为文本或者图片，确定业务访问请求的业务类型为缓存业务；如果业务访问请求中携带的地址信息为即时通信服务提供商SP的地址，确定业务访问请求的业务类型为即时通信业务；否则，确定业务访问请求的业务类型为普通业务。In specific implementation, the identification information includes content type and address information, and the address information can use URL, IP address, etc., and the service type is divided into three types: caching service, instant messaging service and ordinary service. If the content type carried in the service access request is text Or a picture, determine that the service type of the service access request is a cache service; if the address information carried in the service access request is the address of the instant messaging service provider SP, determine that the service type of the service access request is an instant messaging service; otherwise, determine that the service access The requested business type is normal business.
本发明实施例中，为了便于区分，可以将为缓存业务提供服务的服务器分组称为第一服务器分组，相应的WAP代理服务器称为第一WAP代理服务器；将为即时通信业务提供服务的服务器分组称为第二服务器分组，相应的WAP代理服务器称为第二WAP代理服务器；将为普通业务提供服务的服务器分组称为第三服务器分组，相应的WAP代理服务器称为第三WAP代理服务器。In the embodiment of the present invention, in order to facilitate the distinction, the server group that will provide services for the cache service can be called the first server group, and the corresponding WAP proxy server can be called the first WAP proxy server; the server group that will provide services for the instant messaging service It is called the second server group, and the corresponding WAP proxy server is called the second WAP proxy server; the server group that will provide services for common services is called the third server group, and the corresponding WAP proxy server is called the third WAP proxy server.
针对缓存业务的特点，第一WAP代理服务器中缓存最近访问的文本或图片的副本，第一WAP代理服务判断请求访问的文本或图片的副本是否在本地缓存，如果是，将本地缓存的副本返回给移动终端，如果否，则按照现有处理流程执行相应的业务处理。第一WAP代理服务器中缓存的文本或者图片的副本可以通过对应的URL、IP地址等地址信息进行区分。第一WAP代理服务器在缓存副本的有效期内，对于重复的业务访问请求，不再连接到SP，由SP重新传送文本或着图片，只需将本地缓存的副本直接发送给移动终端，从而减少重复请求，节约网络带宽，减少对防火墙连接数的消耗，降低访问时延。For the characteristics of the caching service, the first WAP proxy server caches a copy of the recently accessed text or picture, and the first WAP proxy service judges whether the copy of the text or picture requested for access is cached locally, and if so, returns the copy of the local cache For the mobile terminal, if not, perform corresponding service processing according to the existing processing flow. The copy of the text or picture cached in the first WAP proxy server can be distinguished by corresponding address information such as URL and IP address. During the validity period of the cached copy, the first WAP proxy server no longer connects to the SP for repeated service access requests, and the SP retransmits the text or pictures, and only needs to send the locally cached copy directly to the mobile terminal, thereby reducing duplication request, save network bandwidth, reduce consumption of firewall connections, and reduce access delay.
针对即时通信业务的特点，简化第二WAP代理服务器的处理逻辑，仅实现编解码和协议转换，不进行HTTP header信息的重构，不根据黑、白名单进行前转控制。具体实施中，第二WAP代理服务器将接收到的业务访问请求转换为路由请求，发送给相应SP的业务服务器，并将业务服务器返回的响应数据转发给移动终端。According to the characteristics of the instant messaging business, the processing logic of the second WAP proxy server is simplified, only codec and protocol conversion are realized, and HTTP header information reconstruction is not performed, and forwarding control is not performed according to the black and white lists. In a specific implementation, the second WAP proxy server converts the received service access request into a routing request, sends it to the service server of the corresponding SP, and forwards the response data returned by the service server to the mobile terminal.
针对现有技术中部分服务提供商出现故障时用户频繁连接风暴消耗了大量WAP网关资源影响其它业务使用的问题，本发明实施例进一步提出：对于即时通信业务实施优化的TCP层参数控制，增加连接数的限制，使得处理效率提升，并保证在即时通信服务提供商出现故障时，不影响其它类型业务的使用。具体实施中，如果第二WAP代理服务器没有接收到业务服务器返回的响应数据，向业务服务器再次发送路由请求，直至接收到业务服务器返回的响应数据或者路由请求的发送次数超过连接数门限值。连接数门限值可以综合考虑实际业务需求、SP的稳定性和能力等因素灵活配置。Aiming at the problem in the prior art that frequent user connection storms consume a large amount of WAP gateway resources and affect the use of other services when some service providers fail, the embodiment of the present invention further proposes: implement optimized TCP layer parameter control for instant messaging services, increase connection The limitation of the number improves the processing efficiency and ensures that the use of other types of services will not be affected when the instant messaging service provider fails. In specific implementation, if the second WAP proxy server does not receive the response data returned by the service server, it sends the routing request to the service server again until it receives the response data returned by the service server or the number of times the routing request is sent exceeds the connection number threshold. The threshold value of the number of connections can be flexibly configured by comprehensively considering factors such as actual business requirements, stability and capabilities of the SP.
