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.

Claims

1. An Intelligent Network Control Node connectable to a Mobile Network Switching Node via a control interface and connectable to at least one Intelligent Network application module via an application interface, wherein said Intelligent Network Control Node comprises

a data interface towards said Mobile Network Switching Node for exchanging Short Message Service messages, and

a Transport Layer Controller adapted for sending and receiving Short Message Service (SMS) message via said data interface, said Transport Layer Controller further adapted for correlating said exchange of said SMS messages through said data interface with destination control data exchanged through said control interface, wherein the Transport Layer Controller is further adapted for correlating these SMS messages with a control of SMS message destinations via the control interfaces, and wherein a Correlation Identifier Table holding Correlation Identifiers is used by said Transport Layer Controller for correlating sending and receiving the SMS messages via the data interfaces with the control of SMS message destinations via the control interfaces.

2. The Intelligent Network Control Node as claimed in claim 1, where the Correlation Identifier Table comprises

a pointer for indicating the next free Correlation Identifier to use and

a list of Correlation Identifiers, each Correlation Identifier having a Correlation Identifier Number, a “

FREE/BUSY”

flag for indication that said Correlation Identifier is currently in use or is free,

a Task/process Identifier for identifying an active task or process in the Intelligent Network application module and

a Mobile Party Identifier for identifying a Mobile Terminal.

3. The Intelligent Network Control Node as claimed in claim 1, having

a Relay Layer Controller, an input configured Link Layer Controller and an output configured Link Layer Controller for executing the link and relay layer protocol for sending and receiving the Short Message Service messages via the data interfaces.

4. The Intelligent Network Control Node as claimed in claim 1, where the application interface is adapted for exchanging control messages for controlling the exchange of Short Message Service messages.

5. The Intelligent Network Control Node as claimed in claim 1, where said data interface is compliant with 3GPP MAP protocol.

6. The Intelligent Network Control Node as claimed in claim 1, being one of the group comprising

a Service Capability Server, a combination of a Service Capability Server, an Application Server, a Service Control Point, a combination of a Service Control Point and a Service Data Point, any node performing a Service Control Function, and any combination of nodes performing a Service Control Function.
