Description

大容量分布式信令处理方法及装置
技术领域
本发明涉及通信技术， 特别涉及承载和控制分离的网络中大容量分 布式信令处理方法及装置。
背景技术
现在的电信网是以电话通信为主体设计的网络， 随着因特网业务的 迅速发展， 数据通信业务的增长迅速， 数据通信业务量已超过了电话通 信。 下一代网络 NGN ( Next Generation Network )将是一个以数据通信为 主体， 以分组交换技术为基础的网络， 用新的数字技术来支持各种类型 的通信业务， 包括电话、 电视会议等等实时通信业务。
在 NGN网络中也需要提供综合业务数字网 ISDN( Integrated Services Digital Network ) 业务。
NGN 网络的关键技术是软交换（Softswitch )- 软交换形成分层的全 开放的体系构架， 使得各个运营商可以根据自己的需要， 采用适合自己 的网络解决方案， 例如网间互联协议 IP ( Internet Protocol )、 异步转移模 式、 智能网络和时分多路复用等， 基于这些网絡通信技术充分利用现有 资源， 电信运营商能够利用现有的电话交换网络， 在利用 IP网关架构的 IP网上传输媒体流， 从而为用户提供更广泛的服务。
g前的 IP网关已经实现了业务、 业务控制和信令的分离， IP网关包 括信令网关 SG ( Signaling Gateway )、 媒体网关 MG ( Media Gateway )和 媒体网关控制器 MGC ( Media Gateway Controller )。
SG负责处理信令消息， 将其终结、 翻译或中继； MG负责处理媒体 流，将媒体流从窄带网打包送到 IP网或者从 IP网接收后解包后送给窄带 网； MGC负责 MG的资源的注册和管理， 以及呼叫控制。
信令网关 SG 同媒体网关控制器 MGC 之间一般采用信令传送
( SIGTRAN, Signalling Transport )协议栈通信， SIGTRAN协议栈包括 集成服务数字网络 Q.921用户适配（IUA, ISDN Q.921 -User Adaptation ) 链接访问协议 5用户适配（V5UA, LAPV5 User Adaptation )> 消息传输 部分 2用户适配（ M2UA, MTP2 User Adaptation )等用户适配协议。 当链路发生故障时， 信令网关中央处理器 CPU ( Central Processing Unit )会根据链接访问协议 5 ( LAPV5， Link Access Protocol for V5 )、 Q921 协议或消息传输部分 2 ( MTP2, Message Transfer Part 2 )协议检测到该 故障，并主动上艮给 V5UA、 IUA或 M2UA,再通过 IP连接通艮给 MGC, 使得 MGC很快知道相应信令链路的状态。
在 NGN网络中提供 ISDN业务的标准组网如附图 1所示， 其中在 MG与软交换之间应用 H.248协议。
MG处理 Q.921后， 通过 IUA把 Q.931消息传送到软交换， 软交换 进行 ISDN信令业务处理，然后通过 H.248或媒体网关控制协议（ MGCP, Media Gateway Controller Protocol )控制 MG上的媒体资源进行通话。 IUA 协议栈如附图 2所示。
现有实现中， 以 NGN网络提供的 ISDN业务为例， 都是在软交换和 MG间建立多条 IUA链路或者 V5UA链路， 将这些 IUA链路组成一个或 多个 IUA链路集，一个 IUA链路集之中所有的 IUA链路共同为一组 ISDN 接口服务。 这组 ISDN接口中的信令可以通过对应 IUA链路集中的任何 一条 IUA链路发送，一个 IUA链路中的多条 IUA链路互为备份和负荷分 担。
软交换或者 MG为适应大容量处理， 可以分解为信令处理器和业务 处理器， 信令处理器和业务处理器处于不同的处理器， 同时信令处理器 和业务处理器也是分布式处理， 信令处理和业务处理分布在多个处理器 上， 如附图 3所示。
业务处理根据 ISDN接入线路分布在不同的业务处理板上，信令处理 根据 IUA链路分布 , 也就是说每个信令处理器只处理来自固定 IUA链路 的信令， 处理完 IUA链路送来的信令后需要把业务消息分发到正确的业 务处理器上处理。
在上例中，每个信令处理器都存储有全局的 ISDN接口分布信息，记 录着每个 ISDN接口对应的业务处理器。信令处理器 >据送来的信令中的 ISDN接口标识查询 ISDN接口分布信息， 获得对应的业务处理器， 然后 正确地将信令分发到对应处理器进行业务处理。信令处理器查询的 ISDN 接口分布信息参见图 4。
对于 NGN网络所提供的其它业务，其业务接口分布和业务处理模式 也同样如此。
在实际应用中， 上述方案存在以下问题： 信令处理器需要大量的内 存支持， 而且业务分发效率低下。
造成这种情况的主要原因在于， NGN网络要求能支持大量的业务接 口， 而对于每个信令处理器需要存储全局的业务接口分布信息， 信息量 大。 发明内容
有鉴于此， 本发明的主要目的在于提供一种大容量分布式信令处理 方法及装置， 使得信令处理器对内存的需求减少， 业务分发效率得到提 高。
本发明提供的一种大容量分布式信令处理方法， 在信令处理装置中 设置有信令分发单元和多个具有信令处理功能的业务处理单元， 该方法 包括：
根据业务容量将媒体网关控制器 MGC和媒体网关 MG之间链路划分为 多个链路集， 业务接口分布在所述链路集；
建立所述链路集与业务处理单元之间的对应关系 , 其中每个链路集 对应于一个业务处理单元；
信令分发单元根据所接收到的信令中的链路集标识， 并从所述对应 关系中查找该链路集所对应的业务处理单元， 并将该信令分发到该业务 处理单元。
所述信令为综合业务数字网信令， 所述链路集为集成服务数字网络 Q. 921用户适配链路集。
所述信令为 V5. 2信令， 所述链路集为链接访问协议 5 ( LAPV5 )用户 适配链路集。
所述信令分发单元获取传输所述信令中的链路标识， 并根据该链路 标识查询该链路所在的链路集标识。
所述链路标识和链路集标识的对应关系预先设置在所述信令分发单 元中。
每个所述业务处理单元与一个或多个链路集对应。
本发明还提供一种大容量分布式信令处理装置， 该装置包含至少一 个信令分发单元和至少两个具有信令处理功能的业务处理单元；
所述信令分发单元与至少一个链路集连接， 每个链路集包含至少一 条链路；
所述信令分发单元中设置有各所述链路集与所述业务处理单元的对 应关系， 其中每个所述链路集对应一个所述业务处理单元；
所述信令分发单元用于从所述链路集收到的信令获取传输该信令的 链路集标识， 并从所述对应关系中查找该链路集所对应的业务处理单元 , 并将该信令分发到该业务处理单元。
该信令处理装置的每个所述业务处理单元对应一个或多个链路集。 与现有技术相比较， 本发明提供的大容量分布式信令处理方法及装 置中， 一个链路集只能对应一个业务处理器， 链路集与业务处理器的对 应关系保存在信令处理器中， 信令处理器处理信令时， 根据该信令所携 带的链路标识找到对应的链路集， 再找到对应的业务处理器， 并将该信 令发送到该业务处理器。
由于信令处理器只需要保存链路集与业务处理器的对应关系， 而不 是公知技术中的所有业务接口与业务处理器的对应关系， 而一个链路集 可对应成百上千甚至上万的业务接口， 所以在信令处理器中所需要的内 存大大减少。
因为对应关系大大筒化， 所以在对应关系中的查找操作速度加快， 从而提高业务分发效率。

为使本发明的目的、 原理、 特性和优点更加清楚， 下面将结合附图 对本发明作进一步地详细描述。
本发明的核心在于： 根据实际的业务容量， 将软交换（也可采用其 他媒体网关控制器）和媒体网关 MG间链路划分出多个链路集， 将大量 的业务接口分布在这些链路集上。 一个链路集上的业务接口统一在一个 业务处理器上进行处理。 信令处理器根据信令所携带的链路标识， 查询 得到链路集信息， 得知承载其上的业务接口所对应的业务处理器， 然后 将信令分发到该业务处理器进行业务处理。 业务接口分布信息参见附图 图 6为根据本发明的大容量分布式信令处理装置的结构， 参照图 6。 该装置为媒体网关 MG, 包含有一个信令处理器（至少 1个）， 标识为 60 和两个业务处理器（至少 2个）， 标识分别为 61、 62。 并假设该 MG服务 16000个业务接口， 提供 80条链路为这些业务接口服务。
将所有链路选择平均划分构成 4个链路集， 并分别标识为 LIN 00、 LINK01 , LIN 02、 LINK03= 当由业务接口有信令传入时， 该信令经过 的链路所在的链路集标识将会附在该信令上。
其中， 这 4个链路集均与该信令处理器 60连接， 并且设置业务处理 器 61与链路集 LINK00对应、业务处理器 62与链路集 LINK01-03对应， 然后将这些对应关系保存在信令处理器 60中。
此外， 本发明对链路集和业务处理器之间的对应关系增加了约束， 即每个链路集只对应一个业务处理器。 为了简化说明， 图 6所示的装置只包含一个信令处理器和两个业务 处理器， 在有更多的信令处理器和业务处理器时， 处理方法类似。
下面描述该装置的信令处理方法。
图 7所示为根据本发明的大容量分布式信令处理方法， 参照图 7。 采 用图 6所示的 MG， 同样假设有 16000个业务接口， 有 80条链路并选择 平均划分成 4个链路集（标识分别为 LINK00-LI K03 ), 并假设所处理的 信令为 ISDN信令， 相应地， MG中的链路称为 IUA链路。
步驟 701 ,设定装置中的 80条 IUA链路的标识分别为 link0000-0019、 linl Ol 00-0119 link0200-0219、 link0300-0319, 其中 IUA链路标识前两个 号码分别与 IUA链路集标识对应， 将这种对应关系预置在信令处理器 60 中， 一共四个对应关系。
步骤 702, 设置 IUA链路集 00与业务处理器 61对应， IUA链路集 LINK01-03与业务处理器 62对应， 并将这个对应关系也存入信令处理器 60内存中， 同样共四个对应关系。
步骤 703 , 从业务接口 1发送的 ISDN信令通过 IUA链路 0301传送 到信令处理器 60。 IUA链路标识的信息 0301也一起送达信令处理器 60。
步驟 704, 信令处理器 60获取 ISDN信令所来自的 IUA链路标识， 得到 IUA链路标识 0301。
步骤 705,根据预置在信令处理器 60中 IUA链路与 IUA链路集的对 应关系 , 查询得出 IUA链路 0301对应于 IUA链路集 LIM 03。
步骤 706, 由步骤 705所得到的 IUA链路集的标识 03, 信令处理器 60查询 IUA链路集和业务处理器的对应关系， 得到对应的业务处理器标 识为 62。
对于在步骤 705中和在步谏 706中的两次查询工作， 即在 4条对应 信息中进行两次查询工作。 如果用现有技术， 直接由发送信令的业务接 口的标识 1在 16000个接口标识与业务处理器 61、 62的对应关系进行查 询， 得到对应业务处理器为 62， 也即在 16000条对应信息中进行一次查 询。 很明显本发明的信令的分发效率要高很多。 同样所存储的对应关系 少很多， 因此对信令处理器 60的内存要求要低很多。 步骤 707, 信令处理器 60将该信令发往业务处理器 62处理。 完成了 信令的发布。
上述实施方式中的处理装置都是以 MG为例的， 本领域的普通技术 人员可以理解， 对于软交换也可以采用相同的技术方案。 同样， 上述实 施方式中是以处理 ISDN信令为例的， 对于处理 V5.2信令等其它信令， 其方法也相同， 其中对链路集的划分和链路集与信令处理器、 业务处理 器的对应关系， 相应的对于 V5UA链路也同样适用。
虽然通过参照本发明的优选实施方式， 已经对本发明进行了描述， 但本发明并不仅限于此。 本领域的普通技术人员应该明白， 在不偏离本 发明的精神和范围的前提下进行的各种改变和变更落入本发明的保护范 围。
