Problems solved by technology

Intserv is a flow-based, state-dependent architecture; compared with the state-independent architecture (the original IP network architecture or Diffserv), it provides services with higher flexibility and better service quality guarantee, but the Intserv control mechanism is highly complex, and the scalability and robustness are relatively poor, which hinder the development of Intserv and accelerate the birth of Diffserv

Embodiment Construction

[0021] The invention describes an end-to-end QoS guarantee system based on all IP in a geostationary orbit satellite mobile communication system. By introducing the Diffserv model in the access network like the core network, the end-to-end QoS guarantee problem in the satellite mobile communication network is solved. The QoS guarantee architecture based on the Diffserv model in the access network passes through the terminal-side high-level protocol stack module and the terminal-side air interface protocol stack module, the ground station wireless gateway module, the ground station access routing module, the authentication authorization billing module, and the beam QoS agent module implementation.

[0022] System composition: according to the integrated QoS guarantee system of satellite communication of the present invention, comprise mobile earth terminal QoS guarantee structure and ground station system QoS guarantee structure, such as figure 1 shown. End-to-end QoS guarant...

Abstract

The invention provides a satellite communication integrated QoS (Quality of Service) safeguard system which comprises a QoS safeguard structure of a ground station system and a QoS safeguard structure of a mobile earth terminal. The QoS safeguard structure of the ground station system comprises a wireless gateway module of the ground station, a certificate authority charging module, an access route module of the ground station, and a beam QoS proxy module. The QoS safeguard structure of the mobile earth terminal comprises a terminal side higher layer protocol stack module and a terminal side hollow interface protocol stack module. The satellite communication integrated QoS safeguard system provided by the invention can provide distinguished services for different types services such as voice or video phone service, real-time stream service, interactive services and background services, thereby ensuring the quality of service of services in various types, optimizing the flow of the network and enhancing the user experience.

Description

technical field [0001] The invention belongs to the technical field of satellite mobile communication, and in particular relates to an integrated QoS guarantee system for satellite communication. Background technique [0002] In recent years, GEO satellite mobile communication systems have made great progress, and GEO mobile communication systems such as Inmarsat, Thuraya, MSV, MUOS and ACeS have been put into operation one after another. From the perspective of architecture, GEO satellite mobile communication systems mostly refer to the design scheme of the ground system. In addition to redesigning the air interface according to the characteristics of satellite transmission, the definitions of other system functional entities, interface specifications and signaling systems remain basically unchanged. In the above-mentioned system, Thuraya satellite and ACeS provide communication services compatible with the ground GSM standard. The Inmarsat-4 satellite (for Broadband Glob...
