MTI Server

The MTI Server is the interface layer between the MAP layer and the TCAP layer in the signaling system number 7 (SS7). The main functions are as follows:

• Processing the conversion between signaling at the TCAP layer and that at the MAP layer
• Processing basic dialogs processes, including dialog creation, release, and maintenance, at the MAP layer
• Distributing signaling at the MAP layer among the application modules, including the MAP Server, USSD Gateway and so on, of the MAP layer
• Connecting the application modules at the MAP layer, and distributing messages according to the AC_NAME and SSN of messages

As the server, the MTI Server connects the MAP Server, USSD Gateway, and the signaling access gateway.

When receiving the MAP dialog request at the TCAP layer from the wireless network, the MTI Server sends the request to the corresponding MAP processing module. For dialog requests initiated from the modules of the MAP layer, the MTI Server distributes them to the corresponding signaling access gateway according to a proportion.
