Embodiment Construction
[0051] specific implementation
[0052] Such as figure 1 As shown, the satellite communication system feedback type QoS guarantee system of the present invention is made up of following several modules: master station service identification module 1, master station strategy generation module 2, master station strategy implementation module 3, master station QoS signaling sending module 4 , a small station QoS signaling receiving module 5 , a small station policy implementation module 6 and a master station policy feedback module 7 . The main station service identification module 1 acquires and identifies service application signaling and service data, obtains service characteristic information by analyzing the service application signaling, transmits the service characteristic information to the main station policy generation module 2, and maps the service data to the main station Policy implementation module 3; the service characteristic information includes session ID param...

Disclosed are a feedback QoS (quality of service) safeguard system and a safeguard method for a satellite communication system. The feedback QoS safeguard system comprises a master station service-identify module, a master station strategy-generation module, a master station strategy-implementation module, a master station QoS signal-sending module, a substation QoS signal-receiving module, a substation strategy-implementation module and a master station strategy-feedback module. The feedback QoS safeguard system and the method for the satellite communication system are provided for solving problems that radio resources in the satellite communication system are limited and the satellite network is susceptible to the burst traffic, so that the influence of insufficient radio resources, booming network traffic and reducing channel quality can be resisted by a two-stage feedback method, and the requirements for the satellite communication system QoS safeguarding can be met meanwhile.
Description
technical field [0001] The invention relates to a satellite communication system feedback type QoS guarantee system and guarantee method, which are applied in the satellite communication system. Background technique [0002] With the continuous development of global networking and informatization needs, ground communication networks can no longer meet people's growing multimedia communication needs. The use of communication satellites for efficient data transmission has become an important solution, especially the rapid development of broadband multimedia communication satellite technology. With the development, the satellite communication system can carry a variety of multimedia services, such as video conferencing, VoIP, video calls, Web browsing, FTP downloading, etc. In order to enable users to obtain a good end-to-end service experience, the system needs to provide a reasonable QoS guarantee solution. Due to the limited satellite communication resources, sometimes ther...
