BT CELLNET PRE-PAY ROAMING ENABLED BY TELSIS USSD SOLUTION Wednesday 6 June 2001 PDF Print Lower costs, fast roll-out and proven technical know-how have won mobile value-added services developer Telsis a significant foothold at UK mobile operator BT Cellnet. In an order placed through BT Wholesale, BT Cellnet has rolled out Telsis' USSD pre-pay roaming solution - enabling pre-pay customers to use their phones overseas, and generating immediate revenue, without waiting for new global roaming standard CAMEL to be ratified and widely adopted. "We made our decision after becoming convinced by Telsis' experience in this field and the speed with which they could respond." said Steve Wright of BT Cellnet. "In a sense this is not just an interim solution. Of course we will implement CAMEL at some point in the future, but there will still be a need to support our customers in countries where the new standard has not been adopted, and that means USSD-enabled roaming. The fundamental flexibility of the Telsis solution creates additional future proofing because roaming is just one of many value-added services that it supports." USSD-enabled pre-pay roaming requires the handset user to enter a special USSD string -*111* before dialling the number they wish to reach, followed by the # key. The host network transfers the USSD request to the home network where a switch simultaneously places two calls, one back to the roaming handset, the other to the number the customer dialled. The switch then connects both parties. The service benefits from a unique feature of the Telsis Ocean fastSSP programmable switch - the ability to detect a lack of audio activity on both legs of the call. This ensures that connections are cleared down promptly even when there is a delay in signalling from remote networks, and ensures that the network infrastructure is utilised effectively. In addition to the fastSSP, the Telsis pre-pay roaming solution also includes the Ocean fastTC, a transaction converter which receives and decodes USSD messages, translating them to a TCP/IP protocol. USSD-enabled pre-pay roaming has a number of key advantages. USSD signalling is generic to GSM networks, so operators are not reliant on each other to support pre-pay roaming. Connections are initiated securely, completely under the control of the home network. Monitoring of pre-pay credits used is also centralised. Finally, the Telsis solution is fully enabled by a combination of hardware and software in the host country only, and is proven to integrate quickly with existing infrastructure for fast roll-out. The Telsis family of products enables mobile operators to quickly implement advanced network services for competitive advantage. Telsis solutions are already widely in use with mobile operators around the world. With its headquarters, research and production site in the UK, Telsis has sales and support operations in Australia, France, Germany, Italy, The Netherlands, Singapore and Spain.
