GTS USSD Infrastructure

Unstructured Supplementary Services Data (USSD) is a technology that allows high speed interactive communication between the subscribers and applications across a GSM Network, and hence it supports menus and transactions.

USSD applications can be thought of as an IVR service (Interactive Voice Response) without voice.

A typical USSD request looks like this: *[Shortcode](*text)# (dialed from the phone), where:

  • The asterisk (*) and hash (#) symbols signify the beginning and end of the request.
  • [Shortcode] is the short number associated to the service
  • Asterisks (*) can also be used to send a request containing multiple service keywords to access the different tiers of information.
  • Text is an alphanumeric code of variable length corresponding to an optional keyword of the service.

Some of the USSD services offered by mobile operators to their own subscribers base are:

  • Recharging using prepaid vouchers
  • Balance enquiry
  • Changing tariff plan and subscribing to various VAS services.

Because the response time for USSD messages are shorter than SMS, the USSD service is also suitable for mobile banking & mobile money services offered by third party service providers.

Our USSD VAS infrastructure is based on:

  • A carrier-grade USSD Gateway, with multiple connection links to mobile operators in Nigeria via an Interconnect Services Provider or via Public Internet.
  • A wide range of USSD applications developed and hosted in our USSD Gateway platform or provided in ASP mode by our local or international WASPs partners.

Through our USSD Gateway, GTS-Infotel provide USSD shortcodes services to third party VAS Providers such as licensed mobile-money services operators, wishing to market premium USSD based services to all mobile subscribers via the use of a unique shortcode.

Our USSD Gateway platform supports the following features:

  • Multiple 2-way connectivity to Operators MSC with powerful routing for inbound USSD requests via shortcodes.
  • Multiple 2-way connectivity to third party USSD applications over public Internet via SIGTRAN protocol.
  • Creation of multiple customer accounts (VASP).
  • Hosting & Configuration of multiple USSD based application services.
  • Real time message tracking, reports and statistics accessible per customer & per service.

An extranet account is providing to VASP customers to view statistics and various usage reports of their services.
