Abstract

The invention discloses a method for accurately sending a short message based on a satellite mobile communication system, which comprises the steps of mapping management of a satellite beam and a service area, opening of satellite mobile satellite short message broadcasting capability packaging to the outside, satellite mobile short message service capability sending management, service docking management with an access network GSC and the like. According to the method for accurately sending the short messages of the satellite mobile communication system, the system is integrally designed, the integration degree is high, a uniform external interface is adopted, the data transmission capacity is provided for an area which cannot be covered by a ground network through the existing capacity of moving the first satellite by the existing satellite, and the short messages can be accurately sent within the accurate range. One-way, small-data-volume and real-time broadcast information is provided for specific clients, the utilization efficiency of satellite network resources is improved, the minimum service object of CBS service of the system is the coverage range of a cell (beam) and a BCCH, and when a CBC initiates a short message service to a GSS, a cell list needing to be broadcasted will be attached.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method for accurately sending short messages based on a satellite mobile communication system. Background technique [0002] As the expansion and extension of the land cellular mobile communication system, the satellite mobile communication system can provide users in the coverage area with large-span, large-scale, long-distance roaming, as well as mobile and flexible mobile communication services. It has unique advantages in communications such as islands, disaster-stricken areas, ocean-going ships and aircraft on long-distance voyages. During the operation of the satellite mobile communication system, in order to provide users with high-quality and smooth network services, it is necessary to allow areas not covered by the ground network or areas with poor ground network coverage to receive early warning information from relevant departments. Quickly and effic...
