USSi Gateway Architecture

About USSi Gateway

Pharos' USSD over IP Multimedia Subsystem (USSi) Gateway bridges your existing SS7 mobile network with the rest of the internet-connected world; without you needing to make any changes to your existing USSD applications/services.

The gateway is a SIP-to-MAP protocol convertor that enables smartphone-using subscribers to seamlessly use existing USSD services over 4G/5G. It eliminates the need to switch subscribers over to 2G/3G network to use USSD, which frees-up network signalling and radio resources. As a result, it provides customers with a similar responsive USSD user experience to that provided by 2G/3G.

On top of this, USSi Gateway extends the investment in and lifespan of your existing SS7-based USSD services and infrastructure because it allows you to provide a fluid USSD experience to all subscribers, regardless of their handset radio technology.

With network interfaces for both GSM and IMS, Pharos' USSi Gateway makes the network's USSD technology transparent to applications and subscribers alike.
