Description

实现接入网关业务接入的方法、 设备及系统 技术领域
本发明涉及通信领域的业务接入技术, 尤其涉及一种实现接入网关业 务接入的方法、 设备及系统。 背景技术
云计算是一种新的商业模式, 它是并行计算、 分布式计算和网格计算 的发展, 它以分布式计算、 分布式文件存储、 分布式数据库和分布式数据 緩存技术为实现基础, 将软件、 平台和基础设施通过虚拟化技术, 以服务 的形式提供给第三方用户, 实现了信息和通讯产品从商品化向服务化的转 变。
云计算设施的一个重要特征就是分布式, 在分布式计算的基础上, 通 过虚拟化技术, 釆用动态的资源调度和控制策略, 保证各个服务节点均衡 的负荷分担, 同时根据系统的性能要求, 可动态地实施服务节点的增加或 减少, 也就是系统具备伸缩性( Scalable )。 Webservice技术是面向服务的体 系结构 (SOA, Service-Oriented Architecture ) 实现的基础, 是分布式计算 常用的技术方法之一, 通过 webservice技术, 能够将各种服务能力暴露给 第三方以实现服务的重用。
例如, 现有的一些业务接入网关就是基于 SOA架构构建的信息和通信 技术 ( ICT, Information and Communications Technology ) 融合业务的接入 设备, 在国内外运营商中有着广泛的应用。 这些接入网关的应用系统结构 如图 1 所示, 接入网关支持多种服务能力的提供, 对上层应用服务器如第 三方应用服务器, 提供以 webservice接口为主的服务能力调用接口; 而与 下层的业务引擎如电信网络之间, 通过标准的通讯协议如 7 号信令系统 ( SS7 , Signaling System 7 )、会话启动协议( SIP, Session Initiation Protocol )、 点对点短消息 ( SMPP, Short Message Peer to Peer )等或者 IT服务引擎的 私有 API调用接口, 实现服务功能的适配和实现。
由于这种系统结构简单、 实用, 能够满足第三方应用服务器快速开发 电信业务的要求, 所以推出后不久, 就得到了广泛的应用, 大量的业务提 供商 (SP )基于接入网关开发了许多丰富的融合业务。 然而, 随着系统使 用规模的不断增大, 对系统性能的要求提出了挑战, 接入网关系统不得不 面对经常扩容的要求。 随之而来的是, 系统投入成本的不断增加, 系统升 级和维护的难度在不断地加大。 此外, 在对系统容量预估不准确的情况下, 还会造成系统资源的浪费, 种种不利因素对运营商和设备商来说, 都是极 具挑战性的问题。
上述接入网关基于标准的 ParlayX规范研发,支持语音呼叫( AC , Audio Call )、呼叫通知( CN, Call Notification )、第三方呼叫( TPC , Third Party Call ) 等呼叫类业务的接入以及短信、彩信、 WAP PUSH、 定位等多种数据业务的 接入。 目前, 正在使用的接入网关系统通常釆用图 2所示的组网结构, 以 满足大容量的业务接入需求。 各第三方应用服务器的 webservice请求由作 为负荷分担设备的 F5等四层交换机分发到各个接入网关上处理。 当系统容 量需要增大时, 通过增加接入网关的数量并改变 F5的分发策略来满足容量 需求。 这种组网方式存在如下问题:
第一, 接入网关提供了呼叫类和数据类等多种业务的接入, 不同业务 的接入将占用不同的系统资源。 通常情况下, 呼叫类业务的接入占用的系 统资源较多, 而数据类业务的接入占用的系统资源相对较少。 为保证系统 平稳运行, 通常根据接入网关的实际处理能力, 配置各个业务的最大许可 参数来实现负荷控制。 而在实际使用中, 往往各业务的实际使用量与其最 大许可参数无关, 例如, 在配置时, 呼叫类业务配置较多的系统资源, 数 据类业务会配置较少的系统资源, 如果数据类业务的使用量远远超过呼叫 类业务, 就会导致呼叫类业务所占用的系统资源闲置, 而数据类业务的系 统资源不够用的情况, 使得接入网关系统的处理能力无法有效发挥出来, 造成了资源的浪费;
第二, 接入网关系统的负荷分担策略是静态设定的, 无法根据接入网 关的负荷状况动态调整, 使得各个接入网关的实际运行负荷无法达到均衡 状态;
第三, 接入网关系统在扩容时, 需要停止整个接入网关系统的运行, 之后重新根据各个接入网关的硬件处理能力更改负荷分担策略, 来增加接 入网关实现扩容, 因此, 现有的接入网关系统无法实现整个系统的动态可 伸缩性。 发明内容

步骤 301 : 负荷分担设备实时获取各接入网关的运行参数;
步骤 302: 根据获取的各接入网关的运行参数, 负荷分担设备实时调整 各接入网关上的业务负荷;
步骤 303: 在接收到各应用服务器发送的各业务的接入请求时, 根据所 述调整后的结果, 负荷分担设备将所述的各业务的接入请求分发到各接入 网关, 由各接入网关完成各业务的接入。
这里, 各接入网关的运行参数主要包括: 负荷参数如 CPU的利用率以 及磁盘输出 /输入( I/O , Input/Output ) 等、 当前每秒业务处理量 ( TPS , Transaction Per Second )、 最大综合许可 TPS、 最大许可 TPS。
其中, 当前 TPS表示接入网关对当前各业务的处理性能, 即当前各个 接入网关每秒所处理的各业务的接入请求数目; 最大综合许可 TPS, 是接 入网关同时为预定的多种业务提供接入时, 接入网关所能支持的 TPS; 最 大许可 TPS , 指接入网关仅仅为单一业务提供接入时, 接入网关所能支持 的 TPS。
通常情况下, 由于一个提供多种业务接入的接入网关, 每一业务的接 入处理都要占用相当多的资源, 因此, 接入网关的最大的综合许可 TPS往 往要远小于最大许可 TPS。
具体地, 负荷分担设备获取各接入网关的运行参数的过程, 可以包括: 负荷分担设备定时向各接入网关发送获取运行参数的请求; 各接入网关接 收到所述请求后, 获得自身当前的运行参数, 并发送到所述的负荷分担设 备。 送获取运行参数的请求, 以便实时获取各接入网关的运行参数。
根据各接入网关的运行参数实时调整各接入网关上业务负荷的过程, 具体可以包括: 可以预先在负荷分担设备上设置各接入网关的负荷分担策 略表; 在获取到各接入网关当前的运行参数时, 负荷分担设备根据所获取 的运行参数, 在所设置的负荷分担策略表中选取负荷分担策略, 并根据所 选取的负荷分担策略, 确定当前各接入网关的业务负荷。
根据所述调整后的结果, 负荷分担设备将各业务的接入请求分发到各 接入网关, 具体可以为: 根据所选取的负荷分担策略或所确定各接入网关 当前的业务负荷, 负荷分担设备将各业务的接入请求分发到各接入网关。
这里, 需要说明的是, 负荷分担设备能够针对不同的实际应用情况选 取不同的负荷分担策略。
设置时, 可以在负荷分担策略表中, 根据各业务在不同时间段内的实 际应用情况, 在不同的时间段内, 设置不同的负荷分担策略, 其中的每一 项负荷分担策略则根据各接入网关的运行参数来确定, 负荷分担策略可以 包含在特定时间段内向各接入网关分发业务的接入请求的比例等信息。
在实际应用中, 可以在各接入网关中设置一个独立的代理模块, 该代 理模块在接收到负荷分担设备所发送的获取当前运行参数的请求时, 搜集 接入网关当前的运行参数并上报给负荷分担设备; 负荷分担设备根据各接 入网关当前的运行参数, 选取负荷分担策略并发送给该代理模块, 该代理 模块根据该负荷分担策略, 完成接入网关内各业务负荷的调整。 这里基于 云计算的理念, 在现有接入网关中设置独立的代理模块, 将现有技术的接 入网关改造为具有云计算特征的产品, 实现动态控制和调配各接入网关的 资源, 从而降低运营商的成本。
另外, 在接入网关系统需要扩容时, 所述方法还包括:
新加入的接入网关将自身的运行参数和 /或预设的业务处理请求上报到 负荷分担设备; 负荷分担设备接收所述新加入的接入网关的运行参数和 /或 荷分担设备能够根据更新后的各负荷分担策略, 向各接入网关分发各业务 的接入请求。
具体地, 业务处理请求由人为设定, 包含了新加入的接入网关请求处 理的业务负荷等信息。 新加入接入网关所上报的运行参数包括自身的最大 许可 TPS、 最大综合许可 TPS等。

本发明的实现接入网关业务接入的系统, 主要包括: 上述的负荷分担 设备、 接入网关和应用服务器, 其中:
应用服务器, 用于向所述负荷分担设备发送各业务的接入请求; 负荷分担设备, 用于实时从所述的各接入网关获取运行参数, 并根据 该运行参数, 实时调整各接入网关的业务负荷; 并根据调整的结果, 将所 述应用服务器发送的各业务的接入请求分发到所述接入网关;

所述接入网关, 进一步用于实时向所述负荷分担设备上报自身当前的 运行参数; 所述负荷分担设备, 进一步用于根据所述各接入网关上报的当 前的运行参数, 在已设置的负荷分担策略表中选取负荷分担策略, 并根据 所选取的负荷分担策略来确定各接入网关的业务负荷, 完成所述接入网关 业务负荷的实时调整。
参照图 5 所示, 本发明的实现接入网关业务接入的系统可以包含多个 应用服务器如第三方应用服务器 1、 2 n和多个接入网关如接入网 关 1、 2 n。 其中, 考虑到接口的一致性, 负荷分担设备和各接入网 关之间通过 webservice接口进行通信。
下面结合实例对本发明的具体实现方式做进一步详细说明。
在一个大容量的接入网关系统中, 存在多个接入网关。 其中, 网关 A 和网关 B上都同时提供业务 1的接入和业务 2的接入。 在某一特定的运行 时段, 整个接入网关系统需要提供较高容量的业务 1 的接入, 此时就需要 调整当前各接入网关的业务负荷来满足实际应用的需要, 参照图 6所示, 实现该接入网关系统中网关 A和网关 B业务接入调整的过程, 具体流程如 下:
步骤 601: 负荷分担设备通过 webservice接口向各接入网关发送获取接 入网关 1和接入网关 2运行参数的请求;
步骤 602: 各接入网关在接收到上述的请求之后, 接入网关 、 B分别 向负荷分担设备上报各自当前的运行参数;
步骤 603: 负荷分担设备分别接收接入网关 A和接入网关 B的运行参 数, 并对该运行参数进行分析;
分析得到: 目前接入网关 A和接入网关 B的负荷参数尚未超过预定的 阔值, 但是整个接入网关系统中业务 1的当前 TPS已经达到最大的综合许 可 TPS, 而业务 2的当前 TPS远小于最大综合许可 TPS。 且, 接入网关 A 上业务 2的当前 TPS与接入网关 B上业务 2的当前 TPS之和小于接入网关 B上业务 2的最大综合许可 TPS;
步骤 604: 负荷分担设备根据上述对运行参数分析的结果, 在已设置的 负荷分担策略表中, 选取对应的负荷分担策略;
这里, 所述选取的负荷分担策略具体包括: 业务 2 的接入完全由接入 网关 B来完成, 接入网关 A只负责业务 1的接入。
步骤 605: 负荷分担设备根据所选取的负荷分担策略, 确定接入网关 A 及接入网关 B当前的业务负荷; 和接入网关 B; 接入网关 A接收该负荷分担策略, 卸载自身的业务 2并重 新分配业务 1的可用资源; 同理, 接入网关 B根据该负荷分担策略, 重新 分配业务 1和业务 2的可用资源。
步骤 606: 负荷分担设备在接收到第三方应用服务器发送的业务 2的接 入请求时, 将业务 2的接入请求全部发送到接入网关 B;
步骤 607: 负荷分担设备在接收到第三方应用服务器发送的业务 1的接 入请求时, 以接入网关 A对业务 1的最大许可 TPS为上限, 向接入网关 A 分发业务 1 的接入请求, 使得接入网关系统能够提供高容量的业务 1的接 入。
此时, 由于网关 A上只处理业务 1的接入请求, 它的最大处理能力得 到提升, 可以达到最大许可 TPS , 负荷分担设备根据相应的策略加大向网 关 A分发业务的接入请求 1的分发力度, 整个接入网关系统便可以提供较 高容量的业务 1的接入, 满足第三方应用服务器的需要。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围, 凡在本发明的精神和原则之内所作的任何修改、 等同替换和改进 等, 均应包含在本发明的保护范围之内。
