Description

业务服务质量监测方法、设备及系统
本申请要求于2018年5月21日提交中国国家知识产权局、申请号为201810490079.9、发明名称为“业务服务质量监测方法、设备及系统”的中国专利申请的优先权,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,尤其涉及业务服务质量监测方法、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(5rd generation,5G)网络架构。该架构不但支持3GPP标准组定义的无线技术接入5G核心网络(5G core network),而且支持非3GPP(non-3GPP,N3G)接入技术接入5G核心网络。也就是说,5G网络架构为双接入甚至更多接入的场景提供了可能性。
此外,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业务服务质量监测,这样,当业务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。其中,当前的业务服务质量监测方法中,监测报文与被监测的业务报文采用相同的链路进行发送,这样根据链路上的业务服务质量可以正确反映出该链路的链路质量。同时,监测报文在同一时刻只能监测一条链路上的业务服务质量,无法同时监测多条链路上的业务服务质量。
然而,在多接入的场景下,即针对同一业务存在多条可用链路的场景下,若采用上述业务质量监测方法进行业务服务质量监测,则将导致无法为业务流在多接入切换提供策略决策。
因此,如何进行业务服务质量监测,使得可以为多接入的场景提供多接入链路的业务服务质量的监测,是目前亟待解决的问题。

具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
多接入的5G网络架构:
