Method and system for providing short message service in network interworking between wireless public network and wired/wireless private network

摘要

A method and system for providing a short message service (SMS) in a network interworking between a wireless public network and a wired/wireless private network can provide the short message service through the private network directly when a user wishes to transmit the short message service through the private network in the interworking network. The method includes a first step of setting up an identifier determining through which of the public and private networks to transmit the short message service, and a second step of retrieving the transmitted identifier of a terminal and transmitting the short message service to a corresponding network according to retrieved information. Since it is possible to selectively transmit SMS data using the public network or the private network in the interworking network, and the SMS data can be transmitted to the private network by changing the system without changing the terminal of each user, there occurs no additional expense.
