Overview of SS7 or SIGTRAN Protocol Stacks

Optionally, the Ulticom Signalware SIGTRAN protocol stack can be used to access Signaling System 7 (SS7) networks where the Home Location Register (HLR) database resides. Signalware 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 provides SS7 communication over IP networks.

The SIGTRAN protocol stack is 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 SIM Authentication Module.

For information about installing and configuring the Signalware SS7 or SIGTRAN protocol stacks, see the SBR Carrier Installation Guide.

Caution: On a Linux machine that is installed with Signalware, do not enable SCTP protocol for Diameter connections. Enabling SCTP for both Signalware and Diameter could completely disable SCTP on the machine.
