Intelligent satellite communication system and method based on ip network and e1 network

Abstract

The invention discloses an intelligent satellite communication system and method based on IP network and E1 network. The system includes: a fixed station, a ground communication network and a resource scheduling server. The method includes the steps of: S10, the fixed station channel terminal receives the registration information of the mobile terminal through the satellite; S20, the resource scheduling server connects to the fixed station channel terminal to obtain and stores the registration information of the mobile terminal; S30, when a call occurs, the fixed station intelligent switch queries resources The registration information in the scheduling server is scheduled, and a communication channel is established according to the registration information. By transforming and upgrading the fixed station switch, the present invention connects and communicates with the resource scheduling server, realizes the resource sharing of the satellite communication system, and realizes the unique deployment or unified management of the mobile terminal number, so that when the mobile terminal is called, the call-through rate is greatly improved. improve. The present invention can be widely applied to various satellite communication systems.

Description

technical field [0001] The invention relates to the field of satellite phones, in particular to an intelligent satellite communication system, and also relates to an intelligent satellite communication method. Background technique [0002] TDMA: Time Division Multiple Access, time division multiple access. [0003] FDMA: Frequency Division Multiple Access, Frequency Division Multiple Access. [0004] E1: A pulse code modulation standard. [0005] PSTN: Public Switched Telephone Network, Public Switched Telephone Network. [0006] Satellite communication system is the product of modern mobile communication. Its main function is to fill the areas that cannot be covered by existing communication (wired communication, wireless communication) systems, and provide more comprehensive services for people's work. In modern communication, satellite communication cannot be replaced by other communication methods. All communication functions provided by existing common communication ...

AI Technical Summary

Problems solved by technology

[0008] (1) The fixed station integrated exchange cannot realize resource sharing with the resource scheduling of the satellite communication network;

[0009] (2) The integrated exchange of the fixed station has no mobile management function;

[0010] (3) Since the numbers of mobile terminals registered in different satellite networks are different, the number of the same mobile terminal is not unique, and the call loss is high when it is called, which causes great inconvenience to users
