本发明属于通信领域，涉及一种多协议公共路由管理的装置和方法，且特别涉及一种传统电信网向网际协议 (Internet Protocol)(以下简称 IP)网络演进以及和 IP网络融合过程中的多协议公共路由管理的装置和方法。背景技术 The invention belongs to the field of communications, and relates to a device and a method for multi-protocol public route management, and particularly relates to a network evolution of a traditional telecommunication network to an Internet Protocol (IP) network and an IP network. Apparatus and method for protocol public route management. Background technique

7 号信令 (Signaling System No.7)(以下简称 SS7)是国际电信联盟 (International Telecommunication Union-Telecommunication Standardization Sector, 简称 ITU-T)定义的一组传统电信网的协议，广泛用于公共交换电话网络 (Public Switched Telephone Network, 简称 PSTN)和移动网络。消息传递部分的层 3协议 (Message Transfer Part 3) (以下简称 MTP3)是 Ί号信令网络的网络层协议，主要完成消息处理和信令网管理功能。 Signaling System No.7 (hereinafter referred to as SS7) is a set of traditional telecommunication network protocols defined by the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T), which is widely used in public switched telephones. Public Switched Telephone Network (PSTN) and mobile network. The message transfer part 3 (Message Transfer Part 3) (hereinafter referred to as MTP3) is a network layer protocol of the nickname signaling network, which mainly performs message processing and signaling network management functions.

信令传输 (Signaling Transport) (以下简称 SIGTRAN)协议是互联网工程任务组 (The Internet Engineering Task Force, 简称 IETF)定义的一组用于在新兴 IP电信网络传递传统电路交换网络 (Switch Circuit Network,简称 SCN) 信令的协议，也可用于 IP域内部的点到点之间的互通。消息传递部分第 3 级用户适配层 (MTP3 User Adaptation Layer) (以下简称 M3UA)是 SIGTRAN 协议族中的 MTP3用户适配协议。它为用户提供了等同于 MTP3的服务。 The Signaling Transport (hereinafter referred to as SIGTRAN) protocol is a set defined by The Internet Engineering Task Force (IETF) for transmitting traditional circuit switched networks (Switch Circuit Network) in emerging IP telecommunication networks. SCN) Signaling protocol, which can also be used for point-to-point interworking within an IP domain. The MTP3 User Adaptation Layer (M3UA) is the MTP3 user adaptation protocol in the SIGTRAN protocol suite. It provides users with services equivalent to MTP3.

^ 在电信网络的演进和融合过程中，需要最大可能地保证原有的组网方式和资源继续得到利用而不是被浪费掉，这样就有可能会出现在两个信令 ^ In the evolution and convergence process of the telecommunication network, it is necessary to ensure that the original networking mode and resources continue to be utilized instead of being wasted, so that it is possible to appear in two signalings.

确认本点之间同时存在 SS7和 SIGTRAN传输方式的情况，即 * 'TP3和 M3UA 协议同时维护两信令点之间的路由。这种情况的典型的组网如图 1和图 2 所示。 Confirmation The SS7 and SIGTRAN transmission modes exist simultaneously between the points, that is, * 'TP3 and M3UA protocols maintain the route between the two signaling points at the same time. A typical networking of this situation is shown in Figures 1 and 2.

在图 1中， A、 B两信令点同时釆用 MTP3和 M3UA两种方式互通；在图 2中， A、 B为信令网关， C为 IP域内的信令点， A、 B两信令网关和 C信令点之间有直接 M3UA的传输方式， A、 B两信令网关之间采用 SS7传输方式。从 A信令点看，到 C信令点存在两种路由方式：一种是通过 M3UA方式直接传输；另一种是通过 A到 B信令点的 MTP3方式传输到 B，再由 B信令点转发给 C信令点。 In Figure 1, the two signaling points A and B are mutually interconnected by MTP3 and M3UA. In Figure 2, A and B are signaling gateways, C is the signaling point in the IP domain, and A and B are two letters. There is a direct M3UA transmission mode between the gateway and the C signaling point, and the SS7 transmission mode is adopted between the A and B signaling gateways. From the point of view of the A signaling point, there are two routing modes to the C signaling point: one is directly transmitted through the M3UA mode; the other is transmitted to the B through the MTP3 mode of the A to B signaling point, and then the B signaling is performed. The point is forwarded to the C signaling point.

在两信令点间同时存在 SS7和 SIGTRAN信令传输方式的情况下， MTP3和 M3UA都对用户提供网络层服务，所以存在两种方式路由工作上的配合问题。 MTP3的消息选路是通过预先设置的路由找到信令目的信令点对应的链路组，然后再通过负荷分担算法确定链路组的一条链路； M3UA的消息选路是通过选路关键字匹配来实现的，在 MTP路由头中存在目的地点码 (Destination Point Code, 简称 DPC)、起源点编码 (Originating Point Code, 简称 OPC)、服务信息八位字节 (Service Information Octet, 简称 SIO：)、电路识别码 (Circuit Identification Code, 简称 CIC)等信息，应用服务器 (Application Server) (以下简称 AS)服务这些信息的不同组合所确定的业务，这些信息的不同组合就对应了一个选路关键字；当消息通过选路关键字匹配到一个 AS之后，再通过负荷分担算法匹配到 AS下面的一个应用服务器实例 (Application Server Provider) (以下简称 ASP)。由于 MTP3 和 M3UA分属不同的协议族，它们的路由管理是相对独立的，它们到同一个目的点的路由如何配合，目前还没有任何协议和解决方法。此类问题在具体组网应用上有较大的实际意义，因此需要找到解决方法才能尽量保证原有组网资源不被浪费。发明内容 In the case where both SS7 and SIGTRAN signaling transmission modes exist between the two signaling points, both MTP3 and M3UA provide network layer services to users, so there are two ways of matching the routing work. The MTP3 message routing is to find the link group corresponding to the signaling destination signaling point through the preset route, and then determine a link of the link group through the load sharing algorithm; the M3UA message routing is through the routing keyword. In the MTP routing header, there is a destination point code (DPC), an originating point code (OPC), and a service information octet (SIO:). , Circuit Identification Code (CIC) and other information, Application Server (hereinafter referred to as AS) service services determined by different combinations of these information, different combinations of these information correspond to a routing keyword After the message is matched to an AS through the routing keyword, it is matched to an Application Server Provider (hereinafter referred to as ASP) under the AS through the load sharing algorithm. Since MTP3 and M3UA belong to different protocol families, their routing management is relatively independent, they are the same How to coordinate the routing of a destination point, there is currently no agreement and solution. Such problems have great practical significance in specific networking applications. Therefore, it is necessary to find a solution to ensure that the original networking resources are not wasted. Summary of the invention

The user message processing module performs processing of the user message according to the state of the public route. The public data maintenance module described above maintains public data resources, including static information and dynamically updated information. The above user application maintenance module provides an interface for the user to manage the device.

CRM模块处理路由状态变化的流程图如图 4和图 5所示。在步骤的描述中，可用和不可用路由是指上报状态变化的路由，当前路由是指当前 CRM模块维护的 MTP3和 M3UA公共路由的状态。请同时参照图 4和图 5，本发明所述方法的具体实施步骤如下： The flow chart of the CRM module processing routing state changes is shown in Figure 4 and Figure 5. In the description of the step, the available and unavailable routes refer to the route that reports the status change. The current route refers to the status of the MTP3 and M3UA public routes maintained by the current CRM module. Referring to FIG. 4 and FIG. 5 simultaneously, the specific implementation steps of the method of the present invention are as follows:

步骤 A: CRM模块预先配置 MTP3和 M3UA的路由配合方式；步骤 B_: 当上述 CRM模块收到路由状态变化的上报之后，首先判断配置的路由配合方式；如果是备份方式，则执行步骤 έ_; 如果是负荷分担方式，则执行步骤 D; Step A: The CRM module pre-configures the route coordination mode of the MTP3 and the M3UA. Step B _: After receiving the report of the change of the routing state, the CRM module first determines the configured route matching mode; if it is the backup mode, the step 执行_; if it is the load sharing mode, the step D is performed;

步骤 C: 上述 CRM模块分别配置正常路由和备份路由，其中路由方式优先级的配置原则由配置人员根据组网应用情况和规划而定；之后上述 CRM模块判断收到的路由状态变化的上报的情况，若收到的是 MTP3或 M3UA路由可用的上报，则执行步骤 C10; 若收到的是 MTP3或 M3UA 路由不可用的上报，则执行步骤 C20; Step C: The CRM module is configured with a normal route and a backup route. The configuration principle of the route mode priority is determined by the configuration personnel according to the networking application and the plan. The CRM module determines the report status of the received route change. If the received MTP3 or M3UA route is available for the report, the process proceeds to step C10; if the MTP3 or M3UA route is unavailable, the process proceeds to step C20;

步骤 C10: 上述 CRM模块判断当前路由是否可用，如果当前路由是不可用的，则上述 CRM模块上报用户路由状态变为可用并将当前路由更新为可用路由；否则，执行步骤 C11 ; Step C10: The CRM module determines whether the current route is available. If the current route is unavailable, the CRM module reports that the user routing status becomes available and updates the current route to an available route; otherwise, step C11 is performed;

步骤 C11 : 上述 CRM模块判断上述可用路由的优先级是否高于当前路由的优先级，如果上述可用路由的优先级高于当前路由，则上述 CRM 模块将当前路由更新为高优先级路由，将低优先级路由退出服务；否则，则不更新路由； Step C11: The CRM module determines whether the priority of the available route is higher than the priority of the current route. If the priority of the available route is higher than the current route, the CRM module updates the current route to a high priority route, which is low. The priority route exits the service; otherwise, the route is not updated;

步骤 C20: 上述 CRM模块判断不可用路由的优先级，如果是设置为低优先级的路由变为不可用，则执行步骤 C21 ; 如果是设置为高优先级的路由变为不可用，则执行步骤 C22; Step C20: The CRM module determines the priority of the unavailable route. If the route set to the low priority becomes unavailable, step C21 is performed; if the route set to the high priority becomes unavailable, the step is performed. C22;

步骤 C21 : 上述 CRM模块判断上述不可用路由是否为当前路由，如果不可用路由是当前路由，则将当前路由设置为不可用状态并上报用户；否则，不做更新处理； Step C21: The CRM module determines whether the unavailable route is the current route. If the unavailable route is the current route, the current route is set to an unavailable state and reported to the user; otherwise, the update process is not performed;

步骤 C22: 上述 CRM模块判断低优先级的路由是否为可用状态，如果低优先级的路由可用，则将低优先级的路由置为可用各由；否则，将当前路由置为不可用状态并上报用户； Step C22: The CRM module determines whether the low priority route is available, such as If the low-priority route is available, the low-priority route is set to be available; otherwise, the current route is set to the unavailable state and reported to the user;

其中，在以上步骤中，业务消息的选路都是在当前路由上进行的，当前路由只为 M3UA路由或 MTP3路由的一种，业务消息同样在当前路由内部的多个链路或 ASP上实现负荷分担，实现的机制可以为按照信令链路选择码 (Signaling Link Selection)(以下简称 SLS)轮循或其他实现机制；步骤 D:上述 CRM模块进一步配置 MTP3路由和 M3UA路由的负荷分担比例，其中该负荷分担比例可以为一定值，也可以为一动态变化的值，即根据网络状态进行动态地刷新；之后上述 CRM模块判断收到的路由状态变化的上报的情况，若收到的是 MTP3或 M3UA路由可用的上报，则执行步骤 D10; 若收到的是 MTP3或 M3UA路由不可用的上报，则执行步骤 D30; In the above steps, the routing of the service message is performed on the current route, and the current route is only one type of the M3UA route or the MTP3 route, and the service message is also implemented on multiple links or ASPs in the current route. Load sharing, the implementation mechanism may be a signaling link selection (Signaling Link Selection) (hereinafter referred to as SLS) round robin or other implementation mechanism; Step D: The CRM module further configures the load sharing ratio of the MTP3 route and the M3UA route, The load sharing ratio may be a certain value, or may be a dynamically changing value, that is, dynamically refreshed according to the network status; then the CRM module determines the reported status of the received routing state change, if the MTP3 is received. Or the M3UA route is available for the report, and the step D10 is performed; if the MTP3 or the M3UA route is unavailable, the process proceeds to step D30;

步骤 D10: 上述 CRM模块判断当前路由是否可用，如果当前路由是不可用的，则上述 CRM模块上报给用户路由可用并将当前路由更新为可用路由；否则，执行步骤 D20; Step D10: The CRM module determines whether the current route is available. If the current route is unavailable, the CRM module reports the available route to the user and updates the current route to the available route; otherwise, step D20 is performed;

步骤 D20: 上述 CRM模块将上述可用路由加入当前路由，将其与原路由一起进行负荷分担；其中，如果上述负荷分担比例是动态变化的值，则 CRM模块根据预先设置的 MTP3链路和 M3UA的 ASP的负荷比例和可用个数更新 MTP3路由和 M3UA路由的负荷分担比例，在业务消息的选路时按照最新的负荷分担比例进行负荷分担；其中，路由之间和一种路由内的负荷分担的方式为按照 SLS轮循或其他实现机制； Step D20: The CRM module adds the foregoing available route to the current route, and performs load sharing with the original route. If the load sharing ratio is a dynamically changing value, the CRM module is configured according to the preset MTP3 link and the M3UA. The load ratio of the MTP3 route and the M3UA route are updated by the load ratio and the number of available routes of the ASP. The load sharing is performed according to the latest load sharing ratio when routing the service message. The load sharing between routes and within a route is performed. The method is to follow the SLS round robin or other implementation mechanism;

步骤 30:上述 CRM模块判断另一路由是否还在可用状态，如果可用，则业务消息在剩下的可用的路由上发送；否则，上述 CRM模块将当前路由状态置为不可用并上报用户； Step 30: The CRM module determines whether another route is still available, if available, The service message is sent on the remaining available routes; otherwise, the CRM module sets the current routing state to be unavailable and reports the user to the user;

其中，在上述步骤 D中，在配置 MTP3路由和 M3UA路由的负荷分担比例时，需要考虑 MTP3路由和 M3UA路由两者带宽的匹配和均衡性。若上述负荷分担比例是动态变化的值，则在路由间更新上述负荷分担比例时需要配置 MTP3链路和 M3UA的 ASP 的负荷分担比例。例如，假设 MTP3链路组配置了 2条 2M链路， M3UA路由配置了 2个工作在负荷分担模式下的 ASP，其中 1个 ASP的默认带宽为 2M，则 MTP3链路和 M3UA 的 ASP的负荷分担比例可以设置为 1 :1，也可以设置为其他比例关系，其中影响 MTP3链路和 M3UA的 ASP的负荷分担比例的配置的因素有链路和 ASP的实际带宽，组网应用情况和配置人员的规划等。在正常情况下，所有 MTP3链路和 M3UA的 ASP都可用，则业务消息按照 1 :1的比例在 MTP3路由和 M3UA路由之间进行负荷分担；如果 1条 MTP3链路发生断链，而 2个 ASP均可用，则 MTP3路由和 M3UA的路由负荷分担比例将被更新为 1 :2, 业务消息按照新的负荷分担比例在 MTP3路由和 M3UA路由之间进行负荷分担。 In the foregoing step D, when configuring the load sharing ratio of the MTP3 route and the M3UA route, the bandwidth matching and equalization of the MTP3 route and the M3UA route need to be considered. If the load sharing ratio is a dynamically changing value, the load sharing ratio of the MTP3 link and the M3UA ASP needs to be configured when the load sharing ratio is updated between routes. For example, suppose the MTP3 link group is configured with two 2M links, and the M3UA route is configured with two ASPs working in load sharing mode. The default bandwidth of one ASP is 2M, then the load of the MTP3 link and the M3UA ASP. The sharing ratio can be set to 1:1 or other proportional relationship. The factors that affect the configuration of the load sharing ratio of the MTP3 link and the M3UA ASP are the actual bandwidth of the link and the ASP, the networking application, and the configuration personnel. Planning and so on. Under normal circumstances, all MTP3 links and M3UA ASPs are available, and the service message is load-balanced between the MTP3 route and the M3UA route according to the ratio of 1:1; if one MTP3 link is broken, and 2 If the ASP is available, the MTP3 route and the M3UA route load sharing ratio will be updated to 1:2. The service message is load-sharing between the MTP3 route and the M3UA route according to the new load sharing ratio.

在以上步骤中，当预先设置静态数据后或由于网络状态发生变化而导致路由状态变化的时候，上述 CRM模块都会对相关的数据进行更新并进行维护， BP : 当到一个目的局向的路由状态变为可用以后，上述 CRM模块将可用状态对用户进行上报， MTP3和 M3UA公共的用户就会启动它们的相应业务；面当路由变为不可用的时候，上述 CRM模块 ^会将不可^ 状态对用户进行上报，业务相应变为不可用。其中，用户应用模块对用户提供操作维护和管理的接口，用户可以通过接口进行相关理命令的输入以及状态数据的查看。 In the above steps, when the static data is preset or the routing status changes due to the change of the network status, the CRM module updates and maintains the related data. BP: When the routing status to a destination office direction After becoming available, the above CRM module will report the available status to the user, and the users of MTP3 and M3UA will start their corresponding services; when the route becomes unavailable, the above CRM module will not be able to status. The user reports, and the service becomes unavailable. Wherein, the user application module is for the user An interface for operation, maintenance, and management is provided. The user can input related commands and view status data through the interface.
