Routing control system

Abstract

Abstract PURPOSE:To select a most economical and efficient relay path by utilizing relay network selection information so as to designate all of relay paths and allowing each relay station to recognize the relay network selection information. CONSTITUTION:When a caller 2 makes a prescribed operation to call a called party 6, a caller station 1 sends a call setting message including relay network selection information element having network identifiers '222', '333', '444' to a relay station 3 via a D-channel private line 7a being a first relay path. Thus, the relay station 3 recognizes a relay station 4 as a succeeding relay station and sends the call setting message to the relay station 4 via a D-channel private line 7c. Similarly the relay station 4 recognizes a called station 5 being a final station and sends the call setting message to the called station 5 via a D-channel private line 7e. Then the called party 6 receives the call setting message from the called station 5.
