Embodiment Construction

[0028] Through the description of the embodiments below, the specific implementation of the present invention includes the shape, structure, mutual position and connection relationship between the various parts, the function and working principle of each part, the manufacturing process and the operation and use method of the various components involved. etc., to make further detailed descriptions to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0029] A cross-domain QoE guarantee method for network multimedia services based on isomorphic flows. The method mainly includes three modules: constructing isomorphic flow classification methods, improved QoE prediction methods, and QoE fuzzy control methods. It can dynamically schedule network resources, improve network bandwidth utilization and the number of effective users, reduce packet loss rate, and ensure user Q...

Abstract

The invention discloses a method for ensuring cross-domain QoE of network multimedia service based on an isomorphic flow. The method comprises the following steps: users and service data in a flow library are constructed into isomorphic flow types according to a service preference grade; a user sending terminal sends the multimedia service; a heterogeneous network performs network scheduling according to the isomorphic flow type priority corresponding to the multimedia service; and a service receiving terminal acquires the packet loss probability (PL) in real time.

Description

technical field [0001] The invention belongs to the technical field of software engineering automation, relates to a DiffServ+WLAN+LTE hybrid model network, and in particular to a cross-domain QoE guarantee method for network multimedia services based on isomorphic flow. Background technique [0002] In a large amount of research and analysis on heterogeneous networks (Heterogeneous Networks, HNs), the following problems are found: the classification of network multimedia services is unreasonable, and the consideration of QoE (Quality of Experience) is lacking; typical QoE resource regulation methods ignore user The ambiguity of QoE cannot guarantee different user QoE. [0003] Different networks have different QoS models. For example, four Differentiated Services Code Points (DSCP) are defined in the DiffServ model: Expedited Forwarding (EF) is suitable for low-latency, low-loss, low-jitter, Priority services with guaranteed bandwidth; Assured Forwarding (AF) is divided in...
