Connection Control Part, 简称 SCCP)用户适配层协议 ( SUA) 网络资源管 理的方法及装置。 背景技术
随着软交换技术的应用与推广，传统电信网正朝着与 IP网互通的方向发 展。 在发展过程中遇到的问题是得到广泛使用的 No.7信令如何在 IP网中高 效而可靠的传输， 现有技术中出现了基于 IP技术的 SIGTRAN协议簇， 它主要 包括 No.7信令*** MTP层的适配协议，以提供 No.7信令在 IP网上的传输能 力、 更强的地址映射和路由功能， 以及更简单的管理功能。
SCCP用户适配层（ SCCP User Adaptation Layer,简称 SUA )属于 SIGTRAN 协议族的成员之一， 是 SCCP的上层用户适配协议， 底层承载在流控制传输协 议 （Stream Control Transmission Protocol, 简称 SCTP)之上， 使得 SCCP 的上层用户消息可以在 IP网上传输。 SUA作为 SCCP的上层用户适配协议， 实现的是窄带的 SCCP用户与宽带的 SCCP用户通信，或宽带的 SCCP用户之间 的通信。
信令网关（Signaling Gateway, SG )作为电路交换网与 IP网的交接的 网元，终结电路交换网的信令消息，通过 SUA/SCTP转发窄带侧 ( SS7 )的 SCCP 用户消息至 IP域中能够处理该 SCCP用户消息的信令节点。 同样也可以实现 IP域的 SCCP用户消息通过 SG转发到窄带的 SCCP用户消息处理设备。 信令 网关进程（ Signaling Gateway Process, 简称 SGP)位于网关侧， 因而网关 侧也被称为 SGP侧， 而应用月良务器进程 ( Application Server Process, 简 称 ASP )位于 IP域， IP域也被称为 ASP侧， 这就是 SGP-ASP应用模型。 信令网关 SG与应用服务器 AS (即 SGP-ASP应用模型）之间通过 SCTP偶 联连接。 一条 SCTP偶联由 SGP以及 ASP共同决定， ASP以及 SGP分别看作是 SCTP偶联上的两个端点，在 AS侧表现为 ASP属性，在 SG侧表现为 SGP属性。 为了管理 SGP与 ASP之间的 SCTP偶联， SG上的 SUA需要维护远端 AS上的 ASP 状态， 然而 AS上的 SUA却不需要维护 SGP的状态， 只需维护本端 ASP状态， 当 ASP到 SGP的 SCTP偶联状态正常， 则认为 SGP可用。 因此， 在信令网关 组成 AS的各个 ASP状态决定的。
SG为了在不同的 AS之间进行路由， SG上的 SUA需要维护远端不同的 AS 状态。 AS为了在不同的目的信令点之间进行路由， AS需要维护到达不同目的 信令点的路由状态， 以便确定具体选择哪个 SG进行消息转发。 因此， 信令网 关 SG与应用服务器 AS两端的状态管理存在不一致性、 不对称性。 同样， 在 SG侧， 需要配置到达 AS的相关 AS数据表格， 在 AS侧， 需要配置到达 SG的 相关 SG数据表格， 因此， 数据配置在 SG以及 AS两侧也存在不一致性以及不 对称性。 发明内容

本发明实施例主要提出了一种 SUA网络资源管理方案， 通过建立 SUA实 体、 SUA路由 4、 SUA链路 5以及 SUA链路集等资源对象， 并基于这些资源对 象的参数配置、 状态维护和路由管理等流程， 在本端侧和目的端侧进行配置 管理操作，从而屏蔽 SCTP偶联的两端的属性之间的差异性，便于网络的规划、 维护管理。
如图 1所示， 为本发明 SUA网络资源管理方法实施例的流程示意图。 具 体包括以下步骤：
步骤 101、根据在 SUA网络中建立的统一资源对象对应的属性对网络中的 网元进行配置； 其中， 在 SUA网络中建立的统一资源对象即建立 SUA网络资 源配置模型。 如图 2所示， 图 2为本发明 SUA网络资源管理方法中建立的资 源配置模型实施例的示意图， 图中虚线表示 SUA路由 4 , 细实线表示 SUA链 路 5 , 粗实线表示 SCCP路由 6 , 矩形线框表示 SUA实体， 椭圓线框表示 SUA 链路集。 SUA链路集中的每一条连线都对应一条 SCTP偶联。 建立的 SUA网络 资源对象， 包括以下的任意一个或其任意组合， 但并不限于以下：
SUA实体， 主要表示完成特定功能的逻辑单元， 比如处理特定业务的逻辑 单元如 AS 12、 AS 22 , 或者仅完成特定消息转发功能的逻辑单元， 如 SG 11、 SG21 , SUA实体对象又分为 SUA本地实体和 SUA目的实体。
SUA本地实体， 主要表示在本端完成预定功能的逻辑单元， 如 SG 11 或 AS 12。
SUA 目的实体， 主要表示在目的端完成预定功能的逻辑单元， 如 SG 21 或 AS 22。
SUA链路集 31、 SUA链路集 32、 SUA链路集 33 , 主要用来表示本端与目 的端之间为相同应用服务器服务的所有链路。
SUA路由 4 , 用于表示本端到目的端所经过的路径， 一条 SUA路由 4在本 端对应一条 SUA链路集。
SUA链路 5 , 主要用于表示本端通过流 SCTP建立的与目的端的连接关系， 如 SGP-ASP和 IPSP-IPSP之间通过 SCTP偶联建立的连接关系。
釆用 SUA网络资源配置模型，不论是在 SGP-ASP还是在 IP服务器进程 (IP Service Proces s, IPSP)组网应用模式下， SG与 AS 两端的数据配置、 状态 维护、 路由管理的对象都能够统一为本地实体、 目的实体、 链路集、 路由的 维护与管理； SCTP偶联的管理也能够统一为 SUA链路 5的配置管理。
并且， SUA链路状态取决于其底层对应的 SCTP偶联状态， 因此， 在 SG 侧的 SUA链路状态体现为对应的 ASP状态和 SCTP偶联的状态； 在 AS侧， SUA 链路状态体现为对应 SCTP偶联以及本端 ASP的状态。而 ASP的状态由 SGP与 ASP之间的消息交互完成状态迁移决定， SCTP偶联状态由底层连接状态决定， 使得 SUA链路状态的管理在符合协议的基础上， 统一了维护。 SUA链路集状 态由链路集内的链路状态决定， 而 SUA链路状态在 SGP、 ASP侧实现了统一的 维护， 因此 SG侧的 AS状态属于对应远端服务器的 AS状态， 也保持了一致； 在 AS侧， SUA链路集的状态由本端相关的所有 ASP以及 SCTP偶联的状态统 一决定， SUA链路集状态可取决于本端链路集内的链路的状态， 所以， 只要 链路状态维护统一了， SUA链路集的状态维护管理也就统一了。
SUA路由状态在 SG端由 SUA链路集的状态决定，在 AS端由 SUA链路集状 态以及窄带七号信令网侧的目的信令点状态共同决定。 由于 SUA链路集状态 维护管理能够统一， 因此， SUA路由状态也得到了统一。
SUA目的实体状态取决于到该 SUA目的实体的所有路由的状态，从而使得 SCTP偶联的各网元实体的状态管理得到了统一。
步骤 102、根据配置后的资源对象对应的属性对网络中的各个网元进行管 理。 不同的资源对象对应着不同的属性， 例如 SUA本地实体所对应的属性表 示本地实体在 SUA网络中的特征和位置， 包括但不限于： 本地实体名称、 本 地实体类型、 地址类型和路由上下文等， 或者包括其中的任意一个或其任意 组合。 其中， 本地实体名称用于识别本局实体的命名； 本局实体类型用于表 示本地实体是 SG还是 AS; 地址类型用于表示本地实体釆用的是信令点标识 还是 IP地址标识； 而路由上下文表示根据协议描述区分所服务的 AS。
SUA目的实体对应的属性表示目的实体在 SUA网络中的特征和位置，包括 但不限于： 目的实体名称、 目的实体类型、 本地实体名称、 地址类型、 路由 上下文、 相邻标志和网络模式等， 或者包括其中的任意一个或其任意组合。 其中， 目的实体名称唯一标识了目的实体的名称； 目的实体类型用于表明目 的实体是信令进程（S igna l ing Proces s, SP )、 SG还是 AS , 从而确认对端的 实体属性； 本地实体名称是与目的实体对应的本地实体名称； 而地址类型表 明地址标识是信令点还是 IP地址；路由上下文用于根据协议描述区分所服务 的 AS; 相邻标志表示该实体是否与本局相邻； 网络模式表示目的端是独占信 令点还是共享信令点。
SUA链路集所对应的属性表示本地实体与目的实体之间的链路集模式，包 括但不限于： 链路集名称、 目的实体名称、 业务模式和工作模式， 也可仅包 括其中一个属性或其中各属性的任意组合。 其中， 链路集名称用于显式标识 唯一的链路集； 目的实体名称表示与媒体网关控制器 （Media Ga teway Control ler, MGC )或信令网关相连的相邻实体名称， 对应目的实体中的实体 名称； 业务模式用来指定链路集内部的链路的业务工作模式， 即： 主备方式、 负荷分担方式、 广播等； 工作模式表示链路集中的链路工作在哪种方式， 即 信令网关进程（SGP )、 应用服务器进程 ( ASP )还是 IP服务器进程（IPSP )。
SUA路由 4所对应的属性表示本地实体到目的实体的路由信息，包括并不 限于： 路由名称、 目的实体名称、 链路集名称和优先级， 或者包括其中的任 意一个或其任意组合。 其中， 路由名称用来唯一标识本地的路由； 目的实体 名称表示路由指向的目的实体； 链路集名称表示路由所使用的第一跳路径； 优先级表示该路由在所有到同一目的实体中的优先级， 用于确定到相同目的 实体的消息路由选择优先级。
SUA链路 5对应的属性表示本端与目的端之间的链路及对应的流控制传 输协议偶联建立信息， 包括但不限于： 链路名称、 模块号，链路集名称、 本端
IP地址、 本端口号、 对端 IP地址、 对端端口号、 客户端 /服务器端模式和优 先级等， 或者包括其中的任意一个或其任意组合。 其中， 链路名称用于唯一 的标识本地的链路； 模块号用于指示链路的处理模块； 链路集名称表示该链 路所归属的链路集； 本端 IP地址表示发起 SCTP偶联的本端 IP地址， 可以支 持多址工作方式， 形式可以是 IP地址列表； 本端端口号表示 SCTP偶联建立 所使用的本端 SCTP端口号；对端 IP地址表示发起 SCTP偶联的对端 IP地址， 可以支持多址工作方式， 形式可以是 IP地址列表； 对端端口号表示 SCTP偶 联建立所使用的对端 SCTP端口号； 客户端 /服务器端模式用于指明本端是工 作在客户端 （Cl ient )方式还是服务器（Server )方式， 工作方式主要决定 是由 SGP首先发起 SCTP偶联请求还是由 ASP首先发起 SCTP偶联请求； 优先 级用于指定链路的优先级， 链路选择时可以根据优先级进行选择， 优先选择 优先级高的链路。
针对每个资源对象， 根据网络组网进行配置， 每个资源对象对应一组配 置命令， 可登录本地客户端， 通过配置命令对相应的数据表格进行操作， 提 供给网络配置、 维护的接口， 从而对 SUA网络资源进行配置管理操作， 配置 命令包括但不限于： 增加、 删除、 修改以及查询。 或者通过网管接口下发参 数对 SUA网络资源进行管理操作。
由于各个网元在配置时釆用统一的资源对象对应的属性来配置， 因此克 月良了现有技术中参数配置时连接的两端配置信息不一致的问题。
对 SUA网络资源的配置管理还可包括对资源对象的状态维护。 如图 3所 示， 图 3为本发明 SUA网络资源管理方法中资源对象状态维护的第一实施例 的状态变化示意图。 SUA链路状态取决于其底层对于的 SCTP偶联状态及 SUA 层 ASP的状态迁移， 对应于协议 RFC3332中的 "ASP DOWN" , "ASP INACTIVE"、 "ASP ACTIVE" 0 本实施例可以根据当前的链路集状态或者接收的目的实体发 送的用于指示路由状态的消息， 更新当前 SUA路由 4的可用状态。 例如假设 本地实体的路由状态为可用， 当对应的链路集的状态为不可用时， 或者接收 到目的实体发送来的指示不激活路由可用的消息时， 路由状态将发生迁移， 迁移到不可用的状态（参见图 3中步骤 201 )。 假设本地实体的路由状态为不 可用， 当对应的链路集的状态为可用时， 或者接收到目的实体发送来的指示 激活路由可用的消息时， 路由状态将发生迁移， 迁移到可用的状态 （参见图 3中步骤 202 )。
链路集状态可以由链路集内所有的链路状态决定， 由于釆用本发明实施 例中定义的资源对象， 使得 SUA链路状态在本端和目的端侧实现了统一的维 护， 也就是说， 信令网关侧的应用服务器状态与对应的远端服务器的应用服 务器状态保持了一致； 而在应用服务器侧， 链路集的状态是由本端相关的所 有应用服务器进程以及 SCTP偶联的状态统一决定的。而链路集状态为本端链 路集内的链路的状态的集中表现， 当链路状态维护统一了， 链路集的状态维 护管理也就达到了统一。
对于每个链路的链路状态取决与其底层对应的 SCTP偶联状态， 即在信令 网关侧链路状态体现为对应的应用服务器进程状态和 SCTP偶联的状态； 而在 应用服务器侧，链路状态体现为对应 SCTP偶联以及本端应用服务器进程的状 态。
图 4为本发明 SUA网络资源管理方法中资源对象状态维护的第二实施例 的状态变化示意图。 与上一实施例相比， 本实施例还可以根据当前 SUA路由 状态更新 SUA目的实体的可用状态。 在当前 SUA目的实体的可用状态为可用 时， 如果所有的 SUA路由状态都为不可用， 则更新所述当前 SUA目的实体的 可用状态为不可用 （参见图 4中步骤 203 )。 而当前 SUA目的实体的可用状态 为不可用时， 如果任一 SUA路由状态为可用， 则更新所述当前 SUA目的实体 的可用状态为可用 （参见图 4中步骤 204 )。
对 SUA网络资源的配置管理还可包括路由管理。 图 5为本发明 SUA网络 资源管理方法中路由管理实施例的流程示意图。 从 SUA本地实体到 SUA目的 实体可以存在一条或多条 SUA路由 4 , 所有到达该 SUA 目的实体的路由状态 决定了 SUA目的实体的状态。而对于每条 SUA路由 4可以设定不同的优先级， 到 SUA 目的实体消息选路时可以根据路由选择算法结合路由优先级进行选 择。
SUA链路集由一条或多条 SUA链路 5组成，不同的 SUA链路 5之间可以釆 用主备用或负荷分担两种工作方式。 在主备用方式下， 只能选择主用的 SUA 链路 5 , 当主用 SUA链路故障， 备用 SUA链路上升为主用并承担相应业务； 在负荷分担方式下， 每条 SUA链路 5可以设定不同的优先级， 同一链路集内 优先选择优先级高的 SUA链路 5。 本实施例的路由管理方法的流程如下： 步骤 301、 SUA本地实体分析收到的信令消息， 获取需要发送到达的 SUA 目的实体；
步骤 302、根据预设的路由选择策略和接收到的信令消息中的选路字段选 择符合条件的 SUA路由 4 ;
步骤 303、 根据选择的符合条件的 SUA路由 4获得对应的 SUA链路集； 步骤 304、根据预设的链路选择策略和所述选路字段从对应于符合条件的 SUA路由 4的链路集中选择符合条件的 SUA链路 5;
步骤 305、 根据选路字段在符合条件的 SUA链路 5中选择任一 SCTP偶联 来传输数据。
其中路由选择策略包括但不限于： 为每个用户适配层路由设定不同的优 先级， 并根据优先级进行路由选择； 或在不同的用户适配层路由间釆用负荷 分担的工作方式； 或在不同的用户适配层路由间釆用主备用的工作方式。
链路选择策略包括但不限于： 在不同的用户适配层链路间釆用主备用的 工作方式； 或在不同的用户适配层链路间釆用负荷分担的工作方式； 或为每 个用户适配层链路设定不同的优先级， 并在同一链路集中选择优先级最高的 担。
本实施例提供了灵活的 SUA路由 4选择和链路选择方式， 当链路或路由 出现故障， 能够快速灵活的进行处理， 从而避免对服务产生不良影响。
基于上述方法， 本发明还提供了 SUA网络资源管理装置的实施例，如图 6 所示， SUA网络资源管理装置 60可为通信***中的任意一个网元， 如 MSC、 HLR, 这些网元均包括 SUA部分 63 , 如 SG、 AS等， SUA网络资源管理装置 60 在原有网元基础上还包括接收单元 61和处理单元 62。 接收单元 61接收来自 本地客户端的命令或网管接口下发的参数，这些命令或参数用于为装置 60中 SUA部分 63进行配置或管理， 如， 在 SUA网络中建立 SUA本地实体、 SUA目 的实体、 SUA链路集、 SUA路由 4及 SUA链路 5 , 或者建立其中的任意一个或 其任意组合等统一的资源对象； 或者对建立的资源对象进行修改、 增加或删 除等管理操作。 处理单元 62执行接收单元 61接收到的命令， 或根据接收到 的参数对装置 60中的 SUA部分 63进行配置或管理操作。
