LINE ASSIGNMENT METHOD FOR SATELLITE COMMUNICATION DEMAND ASSIGN EQUIPMENT

摘要

PURPOSE:To automatically transit the titled equipment to a new communication line without intermission of communication and without delay of connection by assigning an idle line when it is available between earth stations in operation so as to continue the communication with respect to a line assignment request with high priority. CONSTITUTION:When a terminal equipment 3-3 of a station 3 presents a line assignment request with high priority to a line used between stations 1, 2, a network control processor (NCP) 2 investigates whether or not the requested line or unit band or the like is in use by referencing a table representing the line setting state possessed by itself to seek an idle line. As a result, when an idle line exists, the NCP 2 assigns the line to station control processors (SCPs)1-1, 1-2 newly and issues a command to the SCPs 1-1, 1-2 to change the trunk. After the transition of line is finished, the NCP 2 sends a line release signal to the SCPs 1-1, 1-2 to release the line in use so far and sends the line assignment signal to the SCP 1-3.
