METHOD FOR COMMUNICATING WITH DESTINATIONS BY USING VIRTUAL SIGNAL POINTS IN A COMMON LINE SIGNAL TYPE SWITCHING CENTER, PARTICULARLY RELATED TO EXPANDING TRUNK CAPACITY BETWEEN DESTINATIONS

摘要

PURPOSE: A method for communicating with destinations by using virtual signal points in a common line signal type switching center is provided to expand trunk capacity between destinations and use more relay resources. CONSTITUTION: Plural virtual signal points exist in one switching center in a common line signal type hierarchy structure divided into an MTP(Message Transfer Part)1, an MTP2, an MTP3, an SCCP(Signal Connection Control Part), a TCAP(Transaction Capabilities Application Part), and a user unit. MDC(Message Discrimination)/MR(Message Routing) and SRM(Signaling Route Management) included in the user unit in a transmitting process and the MTP3 in a receiving process are changed.
