The Telephony Application Server (SVI-TAS) operates over clearly defined API's that present an abstracted version of the underlying DIAMETER, SIP, CAMEL, MAP etc signalling. It can be driven by either Squire Technologies python based client (SVI-TAC) or by operators 3rd party applications, and provides an extremly flexible, service driven platform with huge benefits:
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.
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.
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.
