NetSpira GSN GPRS real-time advanced content rating solution installed at Portuguese mobile Operator Optimus

18 February 2003 - 3GSM Cannes, France

NetSpira Networks today announced that it has successfully completed the delivery of NetSpira GSN, its GPRS real-time advanced content rating product, at leading Portuguese mobile operator, Optimus. With the delivery of this solution, Optimus becomes the first mobile operator in Portugal to be able to rate and bill GPRS/UMTS advanced content in real-time for both pre-paid and post-paid subscribers.

The NetSpira GSN product has been installed in the Optimus network without requiring any upgrades to the existing infrastructure. SchlumbergerSema successfully completed the delivery of the system as the project integrator, developing new functionality on top of the NetSpira GSN product to turn it into a customized solution for Optimus. The solution installed performs GPRS traffic analysis, content filtering and metering to enable real-time rating of advanced data content. This real-time capability has become more critical with the increase in data services because it enables the operator to instantaneously check the pre-paid subscribers' remaining balances before allowing transactions to take place. This same functionality also allows real-time charging of GPRS/UMTS traffic for pre-paid customers when roaming. The solution is based on a flexible platform to allow the easy deployment of GPRS and UMTS value-added services.

"We wanted to work with a technology that could deliver a complete rating solution for GPRS advanced services without any additional investment in network infrastructure and back office systems," commented Rafael Camacho, manager for the Core Network Engineering at Optimus.

"The solution that we have delivered together with our partner, NetSpira Networks, places Optimus in the best position to launch innovative GPRS advanced services and rate them according to new and more profitable business models," stated Rafael Luis, country manager for Portugal at SchlumbergerSema.

"We are very fortunate to have had the opportunity to work with leaders in technology and innovation, like Optimus and SchlumbergerSema, to put in place what is probably the most advanced GPRS real-time content-based charging solution in production at this time," added José López, CEO of NetSpira Networks.
