Abstract
A telecommunication system for transferring SMS messages between a first terminal and at least one second terminal or intelligent network service. The system comprises a mobile telecommunication system (5) and one or more mobile network switching nodes (2) acting as gateway between the mobile telecommunication system (5) and the remainder of the telecommunication system for sending and receiving SMS messages to and from mobile terminals (6a-6z), coupled to an Intelligent Network control node (1) and one or more message servers (3). The Intelligent Network control node (1), is coupled to the mobile network switching nodes (2) and the message servers (3) for providing Intelligent Network services in the telecommunication system. One or more message servers (3), routing messages in the telecommunication system are coupled to the Intelligent Network control node (1) and the mobile network switching nodes (2). The Intelligent Network control node (1) and the mobile network switching nodes (2) are adapted to exchange the SMS messages directly (101b). Further there is provided a method for transferring SMS messages in such a telecommunication system, between the Intelligent Network control node (1) and the mobile network switching nodes (2) among others for interactive message sequences.

8. A method for transferring a Short Message Service message from an Intelligent Network application module via application interface, Intelligent Network Control Node control interfaces and data interface, and Mobile Network Switching Node to a Mobile Terminal, the method comprising the steps of:
-
transmitting the Short Message Service message by the application to an Intelligent Network Control Node via an application interface, forwarding the Short Message Service message by the Intelligent Network Control Node via a data interface to a Mobile Network Switching Node, forwarding the Short Message Service message by the Mobile Network Switching Node to the terminal, and correlating said transferring of said Short Message Service messages through said data interface with destination control data exchanged through said control interface using correlation means, sending a Request CI message by the application module via the application interface to the Intelligent Network Control Node by the application module for initiating a Short Message Service dialogue with the terminal, getting a Correlation Identifier Number indicated by Pointer and returning the Correlation Identifier Number by the Intelligent Network Control Node via the application interface to the application module, storing, by the Intelligent Network Control Node, a Mobile Party Identifier of the terminal and a Task/process Identifier of the application, in a Correlation Identifier Table on a position pointed to by the Correlation Identifier Number in the Short Message Service message, re-forwarding the Short Message Service message by the Intelligent Network Control Node to a Message Server in the event that the Mobile Network Switching Node replies that the Short Message Service message is not deliverable, forwarding the Short Message Service message by the server to a Mobile Network Switching Node, sending an End correlation message by the application module via the application interface to the Intelligent Network Control Node for ending the Short Message Service dialogue with the terminal, stopping correlation by the Intelligent Network Control node in setting a FREE/BUSY flag to “
FREE”
in the table pointed to by the Correlation Identifier Number in the End correlation message, andreturning the End correlation message by the Intelligent Control Node via the application interface to the application module.
