Intelligent satellite communication system and method based on Internet protocol (IP) network and E1 network

Abstract

The invention discloses an intelligent satellite communication system and method based on the Internet protocol (IP) network and the E1 network. The system comprises a fixed station, a ground communication network and a resource scheduling server. The method includes the following steps that S10 a fixed station information channel terminal received registering information of a mobile terminal through a satellite; S20 the resource scheduling server is connected with a fixed station information channel terminal and acquires and stores registering information of the mobile terminal; S30 a fixed station intelligent interchanger inquires the registering information in the resource scheduling server when calling is conducted and builds a communication information channel according to the registering information. By means of the system and the method, the fixed station interchanger is modified and upgraded and is in communication connection with the resource scheduling server to achieve resource sharing of the satellite communication system and achieve sole arrangement or unified management of mobile terminal numbers. When a mobile terminal is called, the calling success ratio is greatly improved. The system and method 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
