METHOD FOR PROCESSING CALL BETWEEN PRIVATE SWITCH NETWORK AND MOBILE COMMUNICATION NETWORK USING WIRELESS RELAY LINE CONNECTION SYSTEM

摘要

PURPOSE: A method for processing a call between a private switch network and a mobile communication network using a wireless relay line connection system is provided for performing a call process for providing a communication service between subscribers based on an inter-working operation through a wireless relay line connection system of a corresponding private switch network in a state that a private switch network and a mobile communication network do not use a public telephone network for thereby simplifying a corresponding call processing procedure and decreasing a call process time and communication charge. CONSTITUTION: A wireless relay line connection system(33) is connected with an analog relay line connector(32-1) of a corresponding private switch(32) and inter-works with a public telephone network(34) in a corresponding wireless relay line connection system(33) and connects a portable terminal(35) for thereby inter-working with a mobile communication network(37) through a wireless trunk. A corresponding private switch network and the mobile communication network(37) inter-work each other.
