SS7 and SIGTRAN Gateway Support
Optionally, the Ulticom Signalware SS7 and SIGTRAN protocol stacks can be used to access Signaling System 7 (SS7) networks where the Home Location Register (HLR) database resides. The Signalware SS7 protocol stack acts as a link between the Steel-Belted Radius Carrier server and the SS7 network. ANSI SS7, CCITT/ITU SS7, Japanese, and Chinese networks are supported. SIGTRAN (provided as a module of Signalware) allows SS7 communication over IP networks.
The SS7 or SIGTRAN protocol stacks are used in conjunction with the optional SIM Authentication module to provide gateway functionality so Steel-Belted Radius Carrier can pass Mobile Access Part (MAP) requests to the SS7 network. MAP requests are passed over the SS7 network to the Home Location Register (HLR), which is the primary subscriber database in the Global System for the Mobile Communications (GSM) network. The HLR then performs a database lookup and returns the requested authentication or authorization information to Steel-Belted Radius Carrier.
To process MAP requests to an HLR, you must configure the optional SIM authentication module. See Chapter 25, SIM Authentication Module.
