Time-delay-evaluating method and device for mobile video service

Abstract

The embodiment of the invention provides a time-delay-evaluating method and a time-delay-evaluating device for a mobile video service and is used for solving a technical problem that the prior art cannot evaluate distribution of a transmitting time delay of the mobile video service in each network segment or node. The method comprises the following steps of: matching a data packet on a first acquisition point with a data packet on a second acquisition point; dividing a transmission path of the service stream containing the data packet into at least two segments by the first acquisition point and / or the second acquisition point; and if the data packet on the first acquisition point is matched with the data packet on the second acquisition point, computing the time delay of the service stream of the data packet between the first acquisition point and the second acquisition point. Compared with the prior art, the invention has the advantages that: by matching the data packets on the acquisition points (not only a receiving end or a sending end), the time delay distribution of the video service can be evaluated according to the network segment and the network segment or network element with the time delay can be precisely located.

Description

technical field [0001] The invention relates to the field of 3G communication, in particular to a method and device for evaluating video service time delay. Background technique [0002] With the commercialization of the third generation mobile communication (3G, the Third Generation) technology, video services, such as mobile video services, develop rapidly. Since video latency is also one of the most important user experience indicators for mobile video services, video latency needs to be evaluated during the development, testing, and network optimization of mobile video service systems. [0003] A method for evaluating mobile video time delay provided by prior art 1 is a manual visual inspection method. The test object (for example, a living person) makes a certain action (for example, waving an arm, etc.), the sending end collects the image corresponding to this action and transmits the image to the receiving end through the network, and the tester visually observes it ...
