Resource distribution method for satellite communication system

Abstract

The invention discloses a resource distribution method for a satellite communication system. The method comprises the following steps that: service general packet radio service (GPRS) supporting node (SGSN) sends a service resource request to a master station according to the service application of an attached satellite terminal; the master station determines a service resource of the service application of the attached satellite terminal according to the service resource request; and the master station receives the data sent by the SGSN according to the service resource. The invention also provides a method for distributing resources to the satellite terminal by the master station in the satellite communication system, and the method comprises the following steps that: the satellite terminal sends resource request signaling to the master station; the master station determines a time slot resource according to the resource request signaling of the satellite terminal; and the satellite terminal sends data to the master station according to the time slot resource determined by the master station. By the method, quality of service (QoS) guarantee strategy of a service is provided for the satellite communication system through 3rd generation (3G) core network mature equipment, the utilization rate of satellite wireless resources is improved by resource distribution for different types of services and signaling, and real-time performance of the bearer service of the satellite communication system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, relates to a resource allocation method of a satellite communication system, and also relates to a resource allocation method between a main station and a satellite terminal in the satellite communication system. Background technique [0002] Compared with other communication technologies, satellite communication has unique advantages, especially it is not affected by geographical environment, location distance and other factors. At present, satellite communication technology is developing rapidly, and the emergence of large-capacity broadband communication satellites makes it possible for satellite communication to carry various multimedia services. With the wide application of satellite communication, the scale of its network continues to expand, and the number of terminals connected to the satellite communication system is also increasing. In the aspect of resource allocation,...
