Description

优化用户设备跟踪可靠性的方法及装置 技术领域
本文涉及通信领域，尤其涉及一种优化用户设备跟踪可靠性的方法及装置。
背景技术
用户设备跟踪(Subscriber and equipment trace)在3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)32.42x和32.44x系列协议中定义为：提供针对移动用户的全网信令跟踪和跟踪数据上报功能。
跟踪会话激活方式有基于管理激活和基于信令激活两种方式。当跟踪会话使用基于信令方式激活时，激活跟踪消息首先发送到归属签约用户服务器(Home Subscriber Server，HSS)或移动网络实体(Mobility Management Entity，MME)(当HSS为异厂商时发给MME)，由HSS或MME单点触发全网基于信令方式激活的跟踪，HSS或MME与其它网元在信令交互时发送激活跟踪消息激活在其它网元上的跟踪会话。在此种情况下，由于用户设备跟踪支持对多个移动用户同时进行全网跟踪，跟踪波及的网元多，跟踪上报的文件数量大，对于跟踪任务的可靠性有着较高的要求，不能因为网元重启或某些异常而导致用户设备跟踪任务丢失，否则后果比较严重，例如：
HSS或MME网元无法正常响应由终端发起的查询当前已激活跟踪用户请求，终端也就无法知悉有哪些用户已被激活跟踪；
HSS或MME网元停止上报之前已激活用户的跟踪数据文件，对正在对这些激活用户的跟踪数据进行收集和分析的系统造成影响。
