Abstract

The invention relates to a Beidou No.3 short message channel scheduling method and system, and provides a terminal-satellite-ground station cooperative transmission mechanism based on an inter-satellite link and a satellite-ground link for a short message packet through operations of initiating a registration request, calculating, searching a table, broadcasting, forwarding, updating the table, returning and the like. By generating respective object service lists in a plurality of satellites and a ground central station, a transmission mechanism is shielded from opposite-end equipment, and the load of a terminal is reduced while the short message data packet is ensured to be accurately transmitted in a channel. The Beidou terminal card has the beneficial effects that single-transmitting and single-receiving, single-transmitting and multi-receiving, multi-transmitting and single-receiving and multi-transmitting and multi-receiving modes of the Beidou terminal card can be realized; all channel links are mutually redundant, and when some facilities break down or are damaged, the robustness is still high.

Description

Technical field [0001] The present invention relates to the field of satellite packets, in particular to a short message channel scheduling method and system for Beidou No.3 short message. Background technique [0002] At present, Beidou No. 3 system has been built. The proposed global short message scheme and regional short message program have been implemented, and in the implemented global short message system scheme, the overseas users of Beidou No. 3 are implemented by the L-band. The short-page transmission of 40 Chinese characters (or 560 bits), while overseas satellites complete the reception of short messages, despread demodulation and information processing, generate user receipt information, and feedback via the B2B frequency. At the same time, through the construction of the interloculture, the user upload information and receipt information to the ground center station. The information that the star is visible by the injection station, and the information to the user...
