一种WAP网关资源的调度方法及相关设备A WAP gateway resource scheduling method and related equipment

技术领域technical field

本发明涉及移动通信领域，尤其涉及一种WAP(Wireless Access Protocol，无线访问协议)网关资源的调度方法及相关设备。The present invention relates to the field of mobile communication, in particular to a WAP (Wireless Access Protocol, wireless access protocol) gateway resource scheduling method and related equipment.

背景技术Background technique

现有移动通信系统提供的各种WAP(Wireless Access Protocol，无线访问协议)业务中，例如WAP浏览业务、基于WAP的MMS(Multi-Media Service多媒体业务)以及通用下载业务等，WAP网关作为接入设备，对WAP业务的支撑起到关键作用，成为用户通过移动终端接入互联网的接入通道。WAP网关在移动通信系统中所处的位置请参见图1，WAP终端通过RAN(Radio AccessNetwork，无线接入网)接入CN(Core Network，核心网)的分组域，WAP网关位于分组域网关设备和业务平台之间，WAP网关与分组域网关设备的互联一般通过WAP业务承载网络连接实现。其中，分组域网关设备具体可以包括GGSN(Gateway GPRS Support Node，网关GPRS支持节点；GPRS：GeneralPacket Radio Service，通用分组无线业务)、NAS(Network Access Server，网络接入服务器)、PDSN(Packet Data Service Node，分组数据服务节点)等。在实际工程建设中，WAP业务承载网络可以采用VPN(Virtual Private Network，虚拟专用网)方式实现，例如采用GRE(General Route Encapsulation，通用路由封装)隧道形成VPN，或者基于MPLS(Multi-Protocol Label Switching，多协议标签交换)技术构建VPN。Among the various WAP (Wireless Access Protocol, wireless access protocol) services provided by the existing mobile communication system, such as WAP browsing service, WAP-based MMS (Multi-Media Service multimedia service) and general download service, etc., the WAP gateway serves as the access Devices play a key role in supporting WAP services and become the access channel for users to access the Internet through mobile terminals. Please refer to Figure 1 for the location of the WAP gateway in the mobile communication system. The WAP terminal accesses the packet domain of the CN (Core Network, core network) through the RAN (Radio Access Network, wireless access network), and the WAP gateway is located in the packet domain gateway device. Between the WAP gateway and the service platform, the interconnection between the WAP gateway and the packet domain gateway device is generally realized through the WAP service bearer network connection. Among them, the packet domain gateway device can specifically include GGSN (Gateway GPRS Support Node, gateway GPRS support node; GPRS: General Packet Radio Service, general packet radio service), NAS (Network Access Server, network access server), PDSN (Packet Data Service Node, packet data service node), etc. In actual engineering construction, the WAP service bearer network can be realized by VPN (Virtual Private Network, virtual private network), such as using GRE (General Route Encapsulation, general route encapsulation) tunnel to form VPN, or based on MPLS (Multi-Protocol Label Switching , multi-protocol label switching) technology to construct VPN.

简单介绍现有WAP业务的实现方案，分组域网关设备以GGSN为例进行说明，包括如下流程：用户的WAP终端首先附着在分组域上，并使用运营商为WAP业务分配的APN(Access Point Name，接入点名称)发起业务访问请求，分组域的SGSN(Service GPRS Support Node，服务GPRS支持节点)根据该APN通过DNS(Domain Name System，域名解析服务器)解析出GGSN的IP地址，并根据解析出的IP地址将业务访问请求发送给GGSN，GGSN根据该APN将业务访问请求路由到对应的外部数据网接口从而到达WAP网关，WAP网关代理用户访问业务平台。Briefly introduce the implementation scheme of the existing WAP service. The gateway device of the packet domain is described by taking GGSN as an example, including the following process: the user's WAP terminal first attaches to the packet domain, and uses the APN (Access Point Name) allocated by the operator for the WAP service. , access point name) initiates a service access request, and the SGSN (Service GPRS Support Node, service GPRS support node) of the packet domain resolves the IP address of the GGSN through DNS (Domain Name System, domain name resolution server) according to the APN, and according to the resolution The outbound IP address sends the service access request to the GGSN, and the GGSN routes the service access request to the corresponding external data network interface according to the APN to reach the WAP gateway, and the WAP gateway accesses the service platform on behalf of the user.

现有技术中，GGSN根据WAP业务的APN对应的外部数据网接口只能访问唯一的WAP网关，并且GGSN唯一可访问的WAP网关是通过人工方式静态配置的。In the prior art, the GGSN can only access the only WAP gateway according to the external data network interface corresponding to the APN of the WAP service, and the only WAP gateway accessible to the GGSN is statically configured manually.

现有WAP业务的实现方案中，由于GGSN只能根据WAP业务的APN对应的外部数据网接口访问唯一的WAP网关，会带来如下技术问题：In the implementation scheme of the existing WAP service, since the GGSN can only access the only WAP gateway according to the external data network interface corresponding to the APN of the WAP service, the following technical problems will be brought about:

由某个GGSN接入的WAP业务只能由特定的WAP网关处理，使得为该GGSN服务的WAP网关的容量必须与该GGSN的容量相匹配，由于一般GGSN和WAP网关在不同的工程项目中建设实施，导致工程建设协调复杂；The WAP service accessed by a certain GGSN can only be processed by a specific WAP gateway, so that the capacity of the WAP gateway serving the GGSN must match the capacity of the GGSN, because generally the GGSN and the WAP gateway are constructed in different projects implementation, resulting in complicated project construction coordination;

由于业务量较大，目前很多运营商部署多台GGSN设备和WAP网关设备，由于每一台GGSN只能访问特定的WAP网关，导致各WAP网关的处理能力无法在不同的GGSN之间共享，使得WAP网关之间的利用率不均衡；Due to the large amount of business, many operators currently deploy multiple GGSN devices and WAP gateway devices. Since each GGSN can only access a specific WAP gateway, the processing capabilities of each WAP gateway cannot be shared among different GGSNs. Uneven utilization among WAP gateways;

在某一台WAP网关发生故障的情况下需要人工切换到该WAP网关的容灾设备，切换时间长，使得系统可靠性低，对业务开展造成不利影响。When a certain WAP gateway fails, it is necessary to manually switch to the disaster recovery device of the WAP gateway. The switching time is long, which makes the system reliability low and adversely affects business development.

具体实施方式Detailed ways

针对现有技术中存在的问题，本发明实施例提供了一种WAP网关资源的调度方案，用以实现对WAP网关资源的集中调度。本发明实施例引入了WAP网关资源调度服务器，将WAP网关作为资源池，基于分布式机制对管理范围的所有WAP网关资源实现集中调度，实现各WAP网关资源利用率的均衡，分组域网关设备在访问WAP网关时能够在WAP网关之间自动切换，实现了网络容灾，提高了系统可靠性。Aiming at the problems existing in the prior art, the embodiment of the present invention provides a WAP gateway resource scheduling scheme to realize centralized scheduling of WAP gateway resources. The embodiment of the present invention introduces a WAP gateway resource scheduling server, uses the WAP gateway as a resource pool, implements centralized scheduling for all WAP gateway resources in the management range based on a distributed mechanism, and realizes the balance of resource utilization of each WAP gateway. When accessing WAP gateways, it can automatically switch between WAP gateways, realizing network disaster recovery and improving system reliability.

本发明实施例提供的WAP网关资源的调度系统架构如图2所示，包括：WAP网关资源调度服务器、多个分组域网关设备和多个WAP网关。分组域网关设备和WAP网关之间的网络组织结构不变，依然采用WAP业务承载网络。需要说明的是，如果现有WAP业务承载网络采用某个分组域网关设备与某个WAP网关之间通过VPN专线或者点对点连接，需要改造成多个分组域网关设备与多个WAP网关之间的网状互通结构。引入的WAP网关资源调度服务器可以由一台计算机实现，通过网络接口接入WAP业务承载网络，通过WAP业务承载网络实现与各分组域网关设备以及WAP网关的通信，WAP网关资源调度服务器通过W1接口与各WAP网关相连、通过W2接口分组域网关设备相连。其中：The architecture of the WAP gateway resource scheduling system provided by the embodiment of the present invention is shown in FIG. 2 , including: a WAP gateway resource scheduling server, multiple packet domain gateway devices, and multiple WAP gateways. The network organizational structure between the packet domain gateway device and the WAP gateway remains unchanged, and the WAP service bearer network is still used. It should be noted that if the existing WAP service bearer network adopts a dedicated VPN line or point-to-point connection between a packet domain gateway device and a certain WAP gateway, it needs to be transformed into a network between multiple packet domain gateway devices and multiple WAP gateways. Mesh interconnection structure. The introduced WAP gateway resource scheduling server can be realized by a computer, accessing the WAP service bearer network through the network interface, realizing communication with each packet domain gateway device and WAP gateway through the WAP service bearer network, and the WAP gateway resource scheduling server through the W1 interface It is connected with each WAP gateway and connected with the packet domain gateway device through the W2 interface. in:

W1接口和W2接口均采用XML(Extensible Markup Language，扩展标识语言)定义，承载协议为HTTP(Hyper Text Transport Protocol，超级文本传送协议)。接口消息采用“请求-应答”方式。请求消息和应答消息均由消息头和消息体两部分组成，消息头包括鉴权信息，消息体包括请求或应答的具体内容。Both W1 interface and W2 interface are defined by XML (Extensible Markup Language, Extensible Markup Language), and the bearer protocol is HTTP (Hyper Text Transport Protocol, Hypertext Transfer Protocol). The interface message adopts the "request-response" method. Both the request message and the response message are composed of a message header and a message body. The message header includes authentication information, and the message body includes the specific content of the request or response.

W1接口的主要功能是：获取所管辖的各WAP网关具备的业务请求处理能力和当前正在处理的业务请求数量，各WAP网关具备的业务请求处理能力一般采用“N次业务请求/秒”的方式表示；The main function of the W1 interface is to obtain the service request processing capability of each WAP gateway under its jurisdiction and the number of service requests currently being processed. The service request processing capability of each WAP gateway generally adopts the method of "N service requests/second" express;

W1接口的主要消息定义如下：The main messages of the W1 interface are defined as follows:

GetWapConfigReq，获取业务请求处理能力请求接口消息；GetWapConfigReq, to obtain the service request processing capability request interface message;

GetWapConfigResp，获取业务请求处理能力应答接口消息；GetWapConfigResp, to obtain the service request processing capability response interface message;

GetWapSessionReq，获取工作状态请求接口消息，其中工作状态即是指当前正在处理的业务请求数量；GetWapSessionReq, to obtain the work status request interface message, where the work status refers to the number of business requests currently being processed;

GetWapSessionResp，获取工作状态应答接口消息。GetWapSessionResp, get the working status response interface message.

W2接口的主要功能是：获取所管辖的各分组域网关设备具备的业务请求处理能力，以及向各分组域网关设备分发WAP网关资源路由表，各分组域网关设备具备的业务请求处理能力同样采用“N次业务请求/秒”的方式表示，当然各分组域网关设备具备的业务请求处理能力也可以采用“PDP激活数/秒”的方式表示，而每个PDP激活需要消耗的WAP网关的业务请求数量一般为常数，所以“N次业务请求/秒”的方式表示和“PDP激活数/秒”的表示方式实质上是一致的。The main function of the W2 interface is to obtain the service request processing capability of each packet domain gateway device under its jurisdiction, and distribute the WAP gateway resource routing table to each packet domain gateway device. The service request processing capability of each packet domain gateway device is also used Expressed in the form of "N service requests/second", of course, the service request processing capability of each packet domain gateway device can also be expressed in the form of "PDP activations/second", and the service of the WAP gateway that each PDP activation needs to consume The number of requests is generally constant, so the expression of "N service requests/second" and the expression of "PDP activation number/second" are substantially the same.

W2接口的主要消息定义如下：The main messages of the W2 interface are defined as follows:

GetGgsnConfigReq，获取业务请求处理能力请求接口消息；GetGgsnConfigReq, to obtain the service request processing capability request interface message;

GetGgsnConfigResp，获取业务请求处理能力应答接口消息；GetGgsnConfigResp, to obtain the service request processing capability response interface message;

DeliveryWapRouteResp，发布WAP网关资源路由表应答接口消息。DeliveryWapRouteResp, publish WAP gateway resource routing table response interface message.

W1接口和W2接口工作过程中，等待应答时使用定时器保护。GetWapConfigReq消息和GetGgsnConfigReq消息可以通过手动配置或者软件配置方式激发，GetWapSessionReq可以根据配置的时间周期定期激发，DeliveryWapRouteReq可以定期或者在新生成WAP网关资源路由表的情况下激发。During the working process of W1 interface and W2 interface, timer protection is used when waiting for a response. GetWapConfigReq message and GetGgsnConfigReq message can be triggered by manual configuration or software configuration, GetWapSessionReq can be triggered periodically according to the configured time period, and DeliveryWapRouteReq can be triggered periodically or when the WAP gateway resource routing table is newly generated.

基于WAP网关资源的调度系统架构，本发明实施例提供了WAP网关资源的调度方法，如图3所示，包括如下步骤：Based on the scheduling system architecture of WAP gateway resources, the embodiment of the present invention provides a scheduling method for WAP gateway resources, as shown in Figure 3, including the following steps:

S301、WAP网关资源调度服务器获取所管辖的各WAP网关当前正在处理的业务请求数量，根据每一个WAP网关当前正在处理的业务请求数量以及该WAP网关具备的业务请求处理能力，确定每一个WAP网关当前的资源利用率；S301. The WAP gateway resource scheduling server obtains the number of service requests currently being processed by each WAP gateway under its jurisdiction, and determines each WAP gateway according to the number of service requests currently being processed by each WAP gateway and the service request processing capability of the WAP gateway. current resource utilization;

具体实施中，WAP网关资源调度服务器获取所管辖的各WAP网关当前正在处理的业务请求数量，可以通过W1接口向各WAP网关发送GetWapSessionReq消息，每一个WAP网关可以通过W1接口将本WAP网关当前正在处理的业务请求数量携带在GetWapSessionResp消息中返回个给WAP网关资源调度服务器，从而WAP网关资源调度服务器可以从接收到的各GetWapSessionResp消息中获取各WAP网关当前正在处理的业务请求数量；In the specific implementation, the WAP gateway resource scheduling server obtains the number of business requests currently being processed by each WAP gateway under its jurisdiction, and can send a GetWapSessionReq message to each WAP gateway through the W1 interface, and each WAP gateway can pass the WAP gateway currently being processed through the W1 interface. The number of business requests processed is carried in the GetWapSessionResp message and returned to the WAP gateway resource scheduling server, so that the WAP gateway resource scheduling server can obtain the current number of business requests being processed by each WAP gateway from each GetWapSessionResp message received;

WAP网关当前的资源利用率等于该WAP网关当前正在处理的业务请求数量与该WAP网关具备的业务请求处理能力之商。The current resource utilization rate of the WAP gateway is equal to the quotient of the number of service requests currently being processed by the WAP gateway and the service request processing capability of the WAP gateway.

S302、WAP网关资源调度服务器确认各WAP网关当前的资源利用率满足WAP网关资源重配置启动条件时，将当前的资源利用率超过资源利用率阈值的WAP网关被分配的业务请求重配置到当前的资源利用率不超过资源利用率阈值的WAP网关上；S302. When the WAP gateway resource scheduling server confirms that the current resource utilization rate of each WAP gateway satisfies the WAP gateway resource reconfiguration start condition, reconfigure the assigned service request of the WAP gateway whose current resource utilization rate exceeds the resource utilization rate threshold to the current resource utilization rate. On WAP gateways whose resource utilization does not exceed the resource utilization threshold;

较佳的，资源利用率阈值为WAP网关资源调度服务器所管辖的所有WAP网关当前的资源利用率的平均值，也可以根据需求对资源利用率的平均值进行适当调整之后作为资源利用率阈值。Preferably, the resource utilization threshold is the average value of the current resource utilization rates of all WAP gateways under the jurisdiction of the WAP gateway resource scheduling server, or the average resource utilization rate may be properly adjusted according to requirements as the resource utilization rate threshold.

S303、WAP网关资源调度服务器根据重配置结果生成当前次的WAP网关资源路由表，并将当前次的WAP网关资源路由表分发给所管辖的各分组域网关设备，其中WAP网关资源路由表用于指示分组域网关设备为激活的会话选择业务数据包路由到的WAP网关；S303. The WAP gateway resource scheduling server generates the current WAP gateway resource routing table according to the reconfiguration result, and distributes the current WAP gateway resource routing table to each packet domain gateway device under its jurisdiction, wherein the WAP gateway resource routing table is used for Instructing the packet domain gateway device to select the WAP gateway to which the service data packet is routed for the activated session;

具体实施中，WAP网关资源调度服务器将当前次的WAP网关资源路由表分发给所管辖的各分组域网关设备，可以通过W2接口向各分组域网关设备发送DeliveryWapRouteReq消息，其中携带当前次的WAP网关资源路由表，每一个分组域网关设备可以从接收到的DeliveryWapRouteReq消息中获取当前次的WAP网关资源路由表，并通过W2接口向WAP网关资源调度服务器返回DeliveryWapRouteResp消息，确认已接收到WAP网关资源路由表；In specific implementation, the WAP gateway resource scheduling server distributes the current WAP gateway resource routing table to each packet domain gateway device under its jurisdiction, and can send a DeliveryWapRouteReq message to each packet domain gateway device through the W2 interface, which carries the current WAP gateway Resource routing table, each packet domain gateway device can obtain the current WAP gateway resource routing table from the received DeliveryWapRouteReq message, and return the DeliveryWapRouteResp message to the WAP gateway resource scheduling server through the W2 interface to confirm that the WAP gateway resource route has been received surface;

相应的，每一个分组域网关设备根据接收到的WAP网关资源路由表更新本地存储的WAP网关资源路由表；并根据更新后的WAP网关资源路由表为新激活的会话选择WAP网关并将业务数据包路由到选择的WAP网关上，以及使用原路由为已经激活的会话路由业务数据包。Correspondingly, each packet domain gateway device updates the locally stored WAP gateway resource routing table according to the received WAP gateway resource routing table; The packet is routed to the selected WAP gateway, and the original route is used to route service data packets for the activated session.

下面，对确认各WAP网关当前的资源利用率满足WAP网关资源重配置启动条件的方法进行详细说明，如图4所示，具体包括：Below, the method for confirming that the current resource utilization of each WAP gateway satisfies the WAP gateway resource reconfiguration starting condition is described in detail, as shown in Figure 4, specifically including:

S401、WAP网关资源调度服务器判断各WAP网关当前的资源利用率是否均超过设定的资源利用率最大值，如果是，则执行S405，如果否，则执行S402；S401. The WAP gateway resource scheduling server judges whether the current resource utilization of each WAP gateway exceeds the set maximum resource utilization, if yes, execute S405, and if not, execute S402;

具体实施中，一般将资源利用率最大值设定为70％，也可以根据需求灵活设置；In the specific implementation, the maximum resource utilization rate is generally set to 70%, and it can also be flexibly set according to the demand;

S402、确定所有WAP网关当前的资源利用率与前一次的资源利用率的方差值，通过如下公式表示：S402. Determine the variance value between the current resource utilization rate of all WAP gateways and the previous resource utilization rate, expressed by the following formula:

$\mathrm{<span><span>\&Delta;</span>\&Delta;</span>}<span><span>=</span>=</span>\sqrt{\underset{\mathrm{<span><span>i</span>i</span>}<span><span>=</span>=</span>\mathrm{<span><span>1</span>1</span>}}{\overset{\mathrm{<span><span>N</span>N</span>}}{\mathrm{<span><span>\&Sigma;</span>\&Sigma;</span>}}}{<span><span>[</span>[</span>{\mathrm{<span><span>P</span>P</span>}}_{\mathrm{<span><span>i</span>i</span>}}<span><span>(</span>(</span>\mathrm{<span><span>n</span>no</span>}<span><span>)</span>)</span><span><span>-</span>-</span>{\mathrm{<span><span>P</span>P</span>}}_{\mathrm{<span><span>i</span>i</span>}}<span><span>(</span>(</span>\mathrm{<span><span>n</span>no</span>}<span><span>-</span>-</span>\mathrm{<span><span>1</span>1</span>}<span><span>)</span>)</span><span><span>]</span>]</span>}^{\mathrm{<span><span>2</span>2</span>}}}$

其中，Δ表示方差值，N表示WAP网关的数量，P_i(n)表示第i个WAP网关当前的资源利用率，P_i(n-1)表示第i个WAP网关前一次的资源利用率；Among them, Δ represents the variance value, N represents the number of WAP gateways, P_i (n) represents the current resource utilization rate of the i-th WAP gateway, and P_i (n-1) represents the previous resource utilization of the i-th WAP gateway Rate;

S403、判断该方差值是否超过设定的方差阈值，一般将方差阈值设定为10％，，也可以根据需求灵活设置，如果是，则执行S404，如果否，则流程结束，也就是说当前次不启动WAP网关资源重配置，不生成新的WAP网关资源路由表而保持上一次的WAP网关资源路由表不变，以避免WAP网关资源路由表的变化振荡；S403. Determine whether the variance value exceeds the set variance threshold. Generally, the variance threshold is set to 10%. It can also be flexibly set according to requirements. If yes, execute S404. If not, the process ends, that is to say Do not start WAP gateway resource reconfiguration this time, do not generate a new WAP gateway resource routing table and keep the previous WAP gateway resource routing table unchanged, so as to avoid the change oscillation of the WAP gateway resource routing table;
