A network multimedia service cross-domain assurance method based on homogeneous multi-image streams

Abstract

The invention discloses a network multimedia service cross-domain guarantee method based on homogeneous multi-image streams. The biggest trend of the real-time communication industry is the guaranteeof the Quality of Experience (QoE). The following problems are found in a large number of researches on a heterogeneous network: in the network resource scheduling process, the typical QoE assessmentmodel ignores the personalized characteristics of a user, and some resource waste phenomena exist in the network service scheduling process. In order to solve the problem, the method mainly comprisesthree aspects of constructing and analyzing user characteristics, proposing an end-to-end guarantee method based on homogeneous multi-image flow and improving a classic QoE evaluation model. The experimental environment is a DiffServer + WLAN + 4G network, and compared with a common mapping table method and an aggregation flow method, the method provided by the invention effectively improves the bandwidth utilization rate, reduces the packet loss rate, and guarantees the number of effective users.

Description

technical field [0001] The invention belongs to the field of network multimedia cross-domain QoE guarantee, and is applicable to DiffServ+WLAN+4G network. Background technique [0002] With the rapid development of mobile communication and Internet technology, a large number of different types of communication networks have emerged, exposing users to complex and diverse heterogeneous network environments. The way information is collected and transmitted, as well as data stored and shared, has changed a lot. Although these heterogeneous networks provide users with a variety of communication modes and network access methods, if they cannot be effectively connected to each other, the quality of user experience cannot be guaranteed, which greatly weakens the effectiveness of the overall network and user service experience. The current service classification has a greater impact on network parameters, but does not take into account user characteristics and users' different prefe...

Problems solved by technology

Although these heterogeneous networks provide users with a variety of communication modes and network access means, if they cannot be effectively connected to each other, the quality of user experience cannot be guaranteed, which greatly weakens the effectiveness of the overall network and the service experience of users.

The current service classification has a greater impact on network parameters, and insufficient consideration of user characteristics and user preferences for services
