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.

Network Monitoring Probe

Prism is a Telecom network monitoring probe that passively monitors your network and produces in near real-time, CDR'S from the low-level signalling protocols traffic.

Supports 3G, 4G, 5G, fixed and mobile networks

Real-time generation of call, session and transaction records
Higher bandwidth hardware accelerated probes of up to 100GB available
Passive monitoring of your network signalling traffic
Advanced packet inspection and protocol discovery
Comprehensive rules-based system to identify traffic for revenue assurance and fraud detection
Seamless integration with Big Data, BSS and Business Intelligence platforms
CSV, SQL, RESTful API integration to 3rd party applications

Support for 3GPP TS 23.066

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.

Reverse IM-SSF

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.

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 as able to push text in menu format to subscriber handsets.

Applications

Pre-Paid Roaming - USSD used in the network to check in real-time
subscriber has enough credit for 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 subscribers credit checks operate correctly in 3G networks.

Example Case Study

Some 3G networks perform credit checks via USSD. The SVI-TAS integrated with a DIAMETER SVI-IWF product is deployed in the clients 4G network to deliver the required USSD to DIAMETER messaging inter-operability. 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 allows our clients to rapidly evolve and extend functionality according to their requirements.

HLR Lookup RESTful API

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.
