A Perfect End-of-Life Alternative

For operators facing the prospect of End-of-Life STP/ITP products, the SVI-STP is perfectly placed as a direct and seamless replacement. With a wealth of experience in replacing end-of-life products, we offer operators a refined process of seamless migrations focussed on minimal disruption, future-proofing and zero loss of services.

“Our migration process takes the strain presented by end-of-life for key network infrastructure, providing fully supported replacement alternatives and a committed long-term roadmap to ensure future-proofing of your networks.”

Real-Time Fraud Prevention

The annual loss globally to the Telecoms industry from fraud is currently estimated by the CFCA (Communications Fraud Control Association) to be $29.2 billion.

Enable the real-time fraud prevention gateway, MavenShield, to:

  • Combat SS7 fraud in real-time
  • Proactively block, tear down, transfer and redirect fraudulent calls
  • Seamless interface to upstream firewall and monitoring applications
  • Deployed in the non-critical path of the network
  • Rapidly provision network lookups aimed at identifying fraudulent traffic

Signalling Firewall

In “reverse” the IM-SSF allows legacy subscribers to access the new services available in an IMS network. It is the glue that allows legacy subscribers to access new services run from SIP application servers – i.e Mobile PBX, OTT etc.

IM-SSF | IP Multimedia Service Switching Function

The SVI-STP supports the 3GPP IMS component the IM-Service Switch Function (IM-SSF) 3GPP 23.278 providing a seamless bridge between an IMS network (SIP) and a CAMEL-based SS7 Intelligent Network via Squire Technologies integrated SVI-TAS Telephony Application Server.

When an operator initially deploys an IMS network they are unlikely to be able to enable all the revenue services available to their existing legacy subscribers. To insure continuity of service the IMS network can leverage the existing Intelligent Network through the IM-SSF component.

USSD Gateway

Unstructured Supplementary Services Data (USSD) is a session-based protocol used in 2G/3G networks to send text between a mobile phone and an application program in the network. Unlike SMS there is no store and forward as USSD transactions only exist for the length of a session. USSD applications are generally menu driven and can push text in a menu format to subscriber handsets.

Applications

  • Pre-Paid Roaming – USSD used in the network to check in real-time
    subscriber has enough credit for a call
  • Pre-paid subscribers – use USSD to manage and top-up their accounts
  • Mobile Money – subscribers able to make payments and purchases
    via their phones menu driven USSD interface

Example Case Study

Working with a 4G mobile operator rolling out roaming services they needed to insure that pre-paid subscriber’s credit checks operate correctly in 3G networks.

USSD Diagram 2

Some 3G networks perform credit checks via USSD. The SVI-TAS integrated with a DIAMETER SVI-IWF product is deployed in the client’s 4G network to deliver the required USSD to DIAMETER messaging interoperability. In a subsequent phase of the project, the client decided to provide their subscribers with a full USSD-driven menu application. This was interfaced and configured using the SVI-TAS to provide the HTTP interface to their OCS platform. This flexibility and ease of deployment allow our clients to rapidly evolve and extend functionality according to their requirements.
