Description

一种分级解耦融合开放的通信开放系统 技术领域
本发明涉及电信技术领域，更具体地，涉及一种分级解耦融合开放的通信开放系统。
背景技术
传统通信网络架构建设效率低、维护成本高、运维难度大，且面向政企客户的通信技术解决方案功能单一，通信接入技术主要存在以下不足：
1、接入效率低：对于企业客户，接入运营商通信网络时客户需分别向各地运营商申请号码资源和线路资源，业务无法同时在全国进行开通。受限于各地运营商的流程复杂性，企业客户要开通全部地区的通信业务的审批手续繁琐，效率低下；
2、维护成本高：对于企业客户，需要在各地市配置通信设备接入到运营商通信网络，以在企业内部形成组网。为保障企业通信业务可用，企业需要在各地市配备专业的通信支撑人员进行属地化维护支撑，专业的通信运维人力成本居高不下；
3、接入周期长，扩容困难：对于企业客户和运营商，现有技术方案通过E1中继电路将客户接入到通信网络，运营商网络侧及客户系统侧需要进行设备建设、线路对接施工，接入周期一般在2-3个月。同时，当业务需求增长需要进行资源扩容时，运营商需要在运营商机房进行硬件升级及线路扩容，数据配置复杂，迭代周期长，无法根据客户的业务峰值为客户周期性动态配置资源，影响客户的业务发展；
4、通信服务内容简单：对运营商，当前的客户通信接入方案仅能为客户提供“哑管道”，无法为客户提供丰富的增值应用，无法提升运营商通信网络价值；
5、通信安全不能有效管控：对运营商，当前的客户通信接入方案依然存在信息安全隐患，用户呼叫行为无法管控、业务内容很难控制、出现投诉时溯源困难等，存在信息安全隐患。

实施例2
本实施例是基于实施例1一种分级解耦融合开放的通信开放系统的具体语音通信的处理流程：
在通话建立前，客户侧呼叫系统通过会话发起协议(SIP，Session Initiation Protocol)协议接入平台的客户对接信令处理模块，向平台的接入代理(proxy)发起呼叫INVITE请求；
平台的接入代理(proxy)将呼叫请求发送给接入人员(worker)集群进行处理；
接入人员(worker)将处理后的呼叫请求发送给大网落地信令处理模块，落地人员(worker)集群将处理后的呼叫请求转交落地代理(proxy)，经过落地代理(proxy)进一步处理后，将呼叫请求送往大网适配模块；
大网适配模块的会话边界控制器(SBC，Session Border Controller)、AS集群、VMSC分别负责引导和疏通固定通信网业务呼叫、移动通信网际互连协议(IP，Internet Protocol)多媒体子系统(IMS，Multimedia Subsystem)域业务呼叫、移动通信服务器-客户机(CS，Client-Server)域业务呼叫；
经过协商建立通话连接后，通话双方的媒体流数据通过媒体处理模块的MS集群进行处理和转发；
在通话结束时，挂断一方发起结束通话请求，结束通话请求经过前述大网落地信令处理模块和客户对接信令处理模块协商后，关闭通话媒体流通道，释放相关通信资源；
在前述通话过程中，有多个不同模块负责对通话的控制、鉴权和路由选择，以此保障通话的稳定性和安全性。其中，计费鉴权控制模块负责对客户呼叫系统的接入许可鉴权；呼叫路由分析模块负责根据当前通信线路运行状态，选择最优的通信连接路径；呼叫控制模块负责控制通话双方的呼叫行为，及时防范不良呼叫骚扰行为；数据缓存与存储模块负责通话数据的实时处理，为上层业务应用提供元数据；
在前述通信能力层之上形成独立的业务应用层，抽取政企客户多样化通信场景的共性需求，封装成云录音、云转写、云质检、云名片、云定位、云识别、云防扰、号码转换等通信 能力应用程序接口(API，Application Programming Interface)或软件开发工具包(SDK，Software Development Kit)，融入客户业务系统，满足复杂通信需求。
显然，本发明的上述实施例仅仅是为清楚地说明本发明技术方案所作的举例，而并非是对本发明的具体实施方式的限定。凡在本发明权利要求书的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
