USSD Gateway www.procescom.com UUSSSSDD GGaatteewwaayy Procescom USSD Gateway Unstructured Supplementary Service Data service (or USSD for short) is one that is today present in almost any mobile network anywhere in the world, yet it is highly underrated and in most cases not utilized to it’s full potential. Typical uses of a USSD service include but are not limited to prepaid call- back services, mobile payment services, menu-driven services such as balance-query service, for automatic configuring mobile stations on the network, or any other service that requires immediate and assured interaction between subscriber and service platform. Procescom USSD Gateway helps operators to minimize Opex costs, protect existing and grow new customers by equipping them with a fully scalable and expandable platform that each mobile operator can adapt according to its specific needs and targeted market segment. It also enables new revenue streams by giving the Internet based part of the industry access to the mobile network. Our USSD Gateway is one of the first fully modular USSD Gateways available on the market. It is suitable for all mobile network technologies and carrier sizes, it enables interworking between 2G, 3G and IP-based core networks, and is fully 4G LTE compliant. It complies for GSM phase 1 and phase 2 standards for push and pull session-based USSD services. When scalability is in question, Procescom USSD Gateway follows “pay-as-you-grow” approach, as our platform may be scaled both horizontally and vertically so to be able to cope with increased traffic loads. What this means is that each operator can purchase only the infrastructure needed for existing operation levels, as it can add additional software and/or hardware components at a later time as the increased traffic needs appear.

How this works is that incoming requests from customer mobile stations are received through a MSC, HLR or VLR connections by using SS7/Sigtran protocol, are then processed on the Gateway itself, translated to 1 HTTP, SMPP, XML or any other industry-standard protocol necessary, and finally handed over to additional service modules over the IP network. As all Procescom mobile solutions, Procescom USSD Gateway has been constructed with flexibility in mind. It’s open design enables it to seamlessly combine and connect with various platforms supplied by different vendors. This enables operators to combine USSD service with other types of mobile services, like text messaging services, collect call/SMS services, mobile banking services, etc. to create unique service offerings no other operators have in their portfolios. Integration with Procescom USSD Gateway is easy and straightforward and significantly shortens the Time-to-Market. Ideally, Procescom USSD Gateway should be combined with Procescom Service Delivery Platform in order to provide for rapid service development environment. Better yet, it could be expanded with other solution platforms available in the Procescom’s portfolio. Some of the choices here are Collect Call and Collect SMS (both of which use USSD for communicating with calling/called parties), Vehicle Tracking (uses USSD to retrieve vehicle’s GPS coordinates), Lite SMS and Text.Me services (use USSD to deliver short text messages), and Balance Portal (provides balance inquiry and top-up functionality, weather, sports, news information services and such).

  • Swiss Federal Railway Uses MATERNA USSD Gateway for Critical GSM-R Communications
    Swiss Federal Railway Uses MATERNA USSD Case Study Gateway for Critical GSM-R Communications Dialogic® TX Series SS7 Board Provides SS7 Connection for USSD Menu-Based Messaging CASE SUMMARY Challenge Swiss Federal Railway (SBB) wanted to take advantage of the new GSM-R standard for railways and add the convenience of menu-based communications and the efficiency of using USSD messaging. Large Logo Solution SBB chose the MATERNA USSD Gateway for its communications network. The USSD Gateway uses the Dialogic® TX Series SS7 Board to enable USSD functionality. Challenge Global System for Mobile Communications - Railway (GSM-R) is an international wireless communications standard for railway communication and applications. GSM-R leverages GSM technology, and aims to become a cost-efficient digital replacement for existing incompatible railway communications networks. Swiss Federal Railways (SBB) wanted to take advantage of GSM-R and combine its efficiencies with those of Unstructured Supplementary Services Data (USSD), a service which significantly Medium Logo accelerates interactive communication between mobile phone users and various applications within the GSM network. When users select a function from their mobile phone menu, USSD messages are transmitted by the mobile handset. Thus, the handset is not only able to deliver static information menus, such as the ones stored on the SIM card, but may also use dynamically created interactive menus delivered by an application in the network. An additional benefit of USSD messages is that they are delivered at a very high speed that allows for interactive menu-driven applications that can reply quickly to the client. Also, USSD messages are mostly free-of-charge or are billed at a very low rate (as of September 2011).

What is so special about SS/USSD? How does it work in commercial networks? How does it work in the Osmocom CNI? Basic configuration examples DEMO Introduction into USSD What is USSD? Unstructured Supplementary Services Data Usually, USSD requests look like: *FOO*BAR# or *#ZOO# e.g. *#100# in both OsmoMSC and OpenBSC Common use cases: Information check applications e.g. account balance, own MSISDN e.g. news, weather, horoscope, etc. Activation / deactivation of (paid) network services Subscriber notifications, advertisements Introduction into Supplementary Services Supplementary Services: Call related (pdisc = GSM48_PDISC_CC) Advice of Charge information multi-party calls call hold Call independent (pdisc = GSM48_PDISC_NC_SS) call waiting service (de)activation call forwarding management What is SS/USSD? A structured kind of call independent Supplementary Services Similar to SMS, but real-time communication is assumed Up to 160 octets payload length Introduction into SS/USSD What is so special about USSD?

  • SGA-USSD USSD-Gateway and Applications Enabling Easy Service Activation and Micropayment
    SGA-USSD USSD-Gateway and Applications Enabling Easy Service Activation and Micropayment Activating Services By Textual Requests SGA-USSD is a modular system for sup- porting enquiry, activation, deactivation or modification of service statuses from the user’s mobile terminal. The usage of such USSD-based applications are as simple as dialing *123*key# - this example would send “key” to service number 123, where the appropriate server would answer the request. AITIA provides a complete, modular, and scalable solution for such services by offer- ing its own implementation of the USSD- Gateway as well as several standalone ser- vices and multipurpose database- interfaces. USSD-Based Solutions AITIA has lots of experience in creating and maintaining complete USSD- based solutions as well as USSD-based service-logic elements. Such services include: • account balance enquiry • account recharge using a voucher number • roaming services activation/deactivation • info-SMS request (e.g., on roaming charges) • call-back applications …and many more. USSD Solutions From AITIA Telecommunications References SGA-USSD provides full USSD Gateway functionality with various applications from roaming activation through balance enquiry to micropayment inter- faces. The SGA-USSD platform consists of two main functional parts: the gateway (SGA-USSD-GW system), and the service logics. AITIA International, Inc.

  • Telenity USSI Gateway USSD Over IMS Gateway
    Telenity USSI Gateway USSD over IMS Gateway For many years, Unstructured Supplementary Service Data (USSD) and USSD based services are widely used by Communication Service Providers (CSP). USSD based services became part of the mainstream services and were highly adopted by end-users. Although many applications have emerged with the possibilities offered by the next-generation network technologies, USSD based services are still preferred for rapid and secure interactive communications and continues to be widely used today. USSD is designed to be a GSM service that allows high-speed interactive communication between the subscribers and applications across a GSM network. Unlike the store and forward mechanism of Short Message Service (SMS), USSD is session-oriented such that when a user accesses USSD service, a session is established, and the connection stays open until the user, application, or time out releases it. This makes USSD attractive for faster and interactive messaging services. On the other hand, LTE networks do not provide built-in integrated services to end- users. To offer such USSD based services to LTE users, separate network enablers and gateways are required to be deployed in the network. Telenity USSD over IMS Gateway (USSI GW) is a next-generation USSD over IMS gateway for service providers, MVNO’s, and wireless operators to offer USSD-based applications and services seamlessly to both GSM (2G/2G) and LTE (4G) subscribers. Telenity’s next-generation consolidated messaging products fulfill ever-increasing expectations and demands of mobile subscribers by offering modular and extensible solutions that enable operators to introduce newly advanced messaging services with ease, based on current and future needs.
