Method and device for measuring quality of experience (QoE)

Abstract

The invention discloses a method for measuring quality of experience (QoE). The method for measuring the QoE comprises the steps that an event message sent by a receiving end is received, and the event message comprises a condition message used for judging the reason why valid media data in a buffer memory of the receiving end are insufficient; whether the insufficient valid media data in the buffer memory of the receiving end are caused by a service system or a user behavior is judged according to the condition message; the reducing degree of the QoE is respectively measured according to different reasons causing the insufficient valid media data in the buffer memory. According to the method for measuring the QoE, the insufficient valid media data in the buffer memory of the receiving end caused by the service system are distinguished from the insufficient valid media data in the buffer memory of the receiving end caused by the user behavior, the reducing degree of the QoE is respectively measured according to different reasons causing the insufficient valid media data in the buffer memory, and therefore the measurement of the QoE is more accurate and objective, and network resources can be utilized more reasonably.

Description

technical field [0001] The invention relates to the field of network management, in particular to a method and device for measuring user experience quality (QoE). Background technique [0002] In network applications, network providers and service providers are often concerned about the service quality of IPTV (Internet Protocol Television, Internet Protocol Television) watched by users, and traditional Quality of Service (QoS) parameters cannot intuitively reflect user experience , in order to more directly express the user's experience effect on IPTV services, the Quality of Experience (QoE) parameter came into being. QoE can be understood as user experience or user perception, that is, the terminal user's subjective perception of the service performance provided by the network. Feeling, which can express the experience and feelings of end users on services and networks through a close to quantitative method, and reflect the gap between the quality of current services and ...

Problems solved by technology

But in fact, the re-buffering of the receiving end may also be caused by user operations. For example, during the media presentation / watching process, the user actively drags and causes the receiving end to send event information. Sending event information is unpredictable and indistinguishable to the QoE monitoring server. However, in the prior art, the QoE server will use the same The QoE measurement method is used to measure the change rate of QoE, and the corresponding QoS adjustment is started according to the change rate of QoE to improve the quality of the network server. However, the network QoS does not decrease when re-buffering is caused by user dragging. At this time, The start of the QoS adjustment strategy will occupy more network resources to a certain extent, thereby increasing the burden on the network and causing unreasonable utilization of resources

In addition, in the existing technology, as long as the QoS drops, it is considered that the QoE will inevitably drop, so that the QoS adjustment will be started immediately. When there is a small drop in QoE caused by occasional jitter or data delay in the network, the QoS adjustment will also be started. As a result, QoS adjustment is not flexible, resulting in unreasonable utilization of network resources
