METHOD AND APPARATUS FOR SETTING TRANSIT CALLS IN SATELLITE COMM

摘要

The present invention relates to a method of setting a transit call in a satellite communication system capable of overcoming a communication failure of a general telephone network which can not communicate locally or geographically by providing a communication path to a general telephone network subscriber and a general telephone network subscriber through a satellite communication network. /RTI ;In the present invention, when the processor 41 of the network control unit 40 that controls the overall satellite communication system has a call request of the general telephone network from any base station connected to the general telephone network (PSTN), the call request message is translated, And searches for and specifies the corresponding base station of the corresponding general telephone network corresponding to the area number in the call request message from the base station information storage section 48. The state information is read from the base station information storage section 45 to check whether the specified base station is in a communication-The modem status data is read out from the modem information storage unit 47 to check the usable modem and allocate it to both base stations.;The processor 41 then checks the currently available communication channel from the channel information storage unit 46 and allocates it to both base stations. The processor 41 transmits the allocated communication modem and communication channel information to the base station A request is sent to the base station, and a call is established between the terminal and the modem through the communication channel, thereby establishing a transit call through the satellite communication network.
