Problems solved by technology

At present, the integrated switches on the fixed stations already in use in the market do not have Ethernet connection and resource scheduling functions, so the channel terminal of the fixed station or resources between multiple fixed stations cannot be shared. When the called channel terminal is busy, the call It cannot be transferred to the idle channel terminal of other fixed stations under the same satellite network, the call cannot be connected in time, the call loss rate is high, and the resources cannot be fully utilized, which brings inconvenience to users

Abstract

The invention discloses a satellite communication call transfer system and method. The system includes fixed station, ground communication network, resource scheduling server, satellite and mobile terminal. The method includes steps: S10, the resource scheduling server obtains and records the channel terminal status of each fixed station; S20, the intelligent switch of the fixed station queries the channel terminal status information in the resource scheduling server, and sets the channel terminal status as busy according to the channel terminal status information. The call is transferred to the channel terminal whose channel terminal state is idle. The invention transforms and upgrades the fixed station exchange to connect and communicate with the resource dispatching server, realizes the resource sharing of the satellite communication system, and realizes the call transfer of the mobile terminal, so that when the mobile terminal is called, the call completion rate is greatly improved. The invention can be widely applied to various satellite communication systems.
