Description

一种获取用户感知的方法、 终端、 网络设备及系统 技术领域
本发明涉及通信领域的用户感知( QoE , Quality of Experience )技术, 特别是指一种获取 QoE的方法、 终端、 网络设备及系统。 背景技术
当前技术中, 网络侧比如数据交换机、 移动数据交换设备、 无线基站、 无线基站控制器等会根据用户的签约信息、 以及当前的网络资源状况, 在 用户发起数据业务时协商出本次业务的服务质量( QoS, Quality of Service ), 也就是说, 在用户发起数据业务时, 就协商出本次业务的策略控制。 这里, 所述 QoS包括: 最大带宽、 最小带宽、 时延、 以及抖动等参数。 由于整个 因特网协议( IP , Internet Protocol ) 网络的 QoS保障属于尽力而为的机制, 因此, 在业务过程中, 随着使用用户数和业务量的变化、 以及用户的移动 等, 用户实际的业务质量会发生变化, 由于网络侧不能得到用户实际感知, 因此, 在业务过程中也无法做出进一步地调控, 具体分析如下:
QoE 受主观和客观两方面因素影响。 其中, 主观因素包括: 价格以及 使用者的背景等, 客观因素则包括: 从终端至接入到网络、 再到业务应用 中的多个跨厂家、 跨网元的设备的运行状态等等。 这里, 所述使用者的背 景包括: 使用者的受教育程度、 消费能力、 以及消费习惯等。
目前, QoE的测量方法, 主要包括以下三种:
