<p><P>PROBLEM TO BE SOLVED: To provide a satellite communication method, a slave station, and a master station capable of suppressing the instantaneous disconnection of voice communication that follows frequency hopping and BOD control, when communicating with an IP telephone connected to the slave station, in a satellite communication circuit of a DAMA method. <P>SOLUTION: Based on the Invite massage issued from an IP telephone connected to a slave station 2, an IP telephone start notice is transmitted from the slave station 2 to a master station 1 through a CSC circuit. At the master station 1 that has received the notice, a communication circuit is changed to an IP telephone circuit. The slave station 2 and the other slave station 2 change the communication circuit, based on a circuit change signal from a master station 2 for communication between an IP terminal and an IP telephone. At the slave station 2 and the other slave station 2 that have started voice communication by IP telephones, the generation of a band change request signal by BOD control is stopped. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
