The present application provides a satellite communication system and a method for accessing the satellite communication system, which relate to the technical field of satellite communication. A method for accessing a satellite communication system, comprising: a satellite load signaling processing unit sends a first broadcast message to a coverage cell through a signaling beam, the first broadcast message includes an ephemeris message; a satellite terminal transmits a message according to the first broadcast The message adjusts the beam pointing, and reports the cell ID of the serving cell; the satellite load signaling processing unit schedules the service beam to cover the serving cell according to the cell ID; the satellite terminal is controlled by the service beam The signaling of the channel is connected to the satellite communication system. According to the technical solution of the embodiment of the application, the signaling beam and the service beam are independently designed, and the broadcast channel and the service beam interact with the signaling content of the control channel to solve the problem of ephemeris synchronization and multiple User management issues.
Description
technical field [0001] The present application relates to the technical field of satellite communication, in particular, to a satellite communication system and a method for accessing the satellite communication system. Background technique [0002] Traditional satellite communication systems mostly use the working mode of resource pre-allocation to provide users with point-to-point data transmission services, which cannot support the random access of massive users and the flexible and dynamic on-demand allocation of resources on the satellite. The DVB-S2X standard provides physical layer and MAC layer protocols, but lacks multi-user management high-level protocols. 5G NR technology provides access and multi-user management solutions for ground mobile communication users, but it still cannot support the access and multi-user management of low-orbit satellite Internet users. Contents of the invention [0003] Based on this, the present application provides a satellite comm...
