Beidou rdss system user machine inbound and outbound message management method and user machine

Abstract

The invention discloses an outbound / inbound message management method of a Beidou RDSS system user machine and the user machine. The outbound / inbound message management method comprises the steps: an initial phase manager confirms a state controller of an encryption / decryption module corresponding to a message according to a user identification included in each outbound / inbound message and forwards each outbound / inbound message to the state controller of the corresponding encryption / decryption module to be processed through an outbound / inbound message controller, wherein the user machine protects at least two encryption / decryption modules, and each encryption / decryption module is controlled by one state controller. By adopting the method and the user machine, outbound / inbound data management and control of multiple modules can be achieved, and accordingly the user machine can manage multiple subordinate users, meet the demand of high-end customers and achieve encryption / decryption of the outbound / inbound data of multiple modules. In addition, the communication bandwidth can be remarkably increased, and the communication congestion problem can be solved.

Description

technical field [0001] The present invention relates to the field of satellite communication, in particular to a method for managing inbound and outbound messages of a Beidou radio determination satellite service (Radio Determination Satellite Service, RDSS for short) system user machine and the user machine. Background technique [0002] The dispatch management user machine of Beidou RDSS system is mainly used for data communication with Beidou communication satellites. At present, the scheduling management user machines on the market generally only support a single encryption / decryption module, complete the data monitoring and collection of the subordinate users of the encryption / decryption module, and realize the functions of active positioning and short message communication of the RDSS system through satellites . [0003] figure 1 Currently, it supports a single-module scheduling management user machine for inbound and outbound message management. A user machine only ...

AI Technical Summary

Problems solved by technology

However, compared with single-module scheduling management user machines, the inbound and outbound data management methods and control processes of multi-module scheduling management user machines are more complicated. At present, the industry has not proposed a solution for Beidou multi-module scheduling management user machines.
