Description

服务质量监测方法、设备及系统
本申请要求了2018年8月13日提交的、申请号为201810918390.9、发明名称为“服务质量监测方法、设备及系统”的中国申请的优先权，以及2019年1月11日提交的、申请号为201910028864.7、发明名称为“服务质量监测方法、设备及系统”的中国申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及服务质量(quality of service，QoS)监测方法、设备及系统。
背景技术
为了应对无线宽带技术的挑战，保持第三代合作伙伴计划(3rd generation partnership project，3GPP)网络的领先优势，3GPP标准组在2016年底制定了下一代移动通信系统(next generation system)网络架构，称为第五代(5th generation，5G)网络架构。
5G网络架构中定义了极高可靠性低时延通信(ultra-reliable low latency communication，URLLC)场景，主要包括如无人驾驶、工业自动化等需要低时延、高可靠连接的业务。其中，5G网络的先进空口技术和优化的核心网络架构，使得上述场景的要求成为可能。但是，5G网络自身不管是底层链路还是上层路由协议等均存在一定的不稳定性；同时，从网络建设的角度，时延、差错甚至网络故障总是不可避免的，而上述场景多为生命安全或生产安全相关的业务，容不得差错。因此，当我们使用5G网络服务于上述生命安全或者生产安全敏感的行业时，需要5G网络能够提供实时的服务质量监测，当服务质量不满足预设条件时，可以采取相应的调整措施或者保护措施，从而能够为用户选择满足服务要求的链路。
目前，现有技术中虽然提出了各个分段传输时延信息的监测方式，如终端和接入设备之间的传输时延信息的监测，接入设备和用户面网元之间的传输时延信息的监测，或者终端和用户面网元之间的传输时延信息的监测，然而，如何简化分段传输时延信息的监测方法，使得可以在一次分段传输时延信息的监测流程中获取多个分段传输时延的信息，目前并没有相关的解决方案。
