A flying leap for 3G communications
Third-generation communications promise to open up a new world of personalised multimedia and location-based services. Turning this promise into reality is an operation support system (OSS) architecture for service and network providers.
Focused on key areas of 3G service provision, including quality of service monitoring, aggregated services and roaming management, the OSS architecture developed by IST project AlbatrOSS was validated in trials that not only proved the need for advanced support systems to make 3G a commercial reality, but also offered insights into the potential of next-generation mobile communications.
“Existing OSS do not offer the functionalities required to support 3G networks and services,” explains project manager Conor Ryan at TSSG in Ireland. “The 3G world is a convergence of Internet and telecoms, and traditional OSS have been built purely to support telecoms… hence they struggle to support the wider scope of applications and services that have emerged from the realm of the Internet.”
The AlbatrOSS architecture overcomes these legacy problems and does so over a range of access networks, including UMTS, GPRS, local area networks (LANs) and wireless local area networks (WLANs).
Perhaps the most notable achievement of the AlbatrOSS project is in the field of service roaming, where the OSS allows mobile devices to automatically switch between providers of different access networks. In such a way, users could watch multimedia broadcasts over a LAN in their office, over a WLAN in the street outside and over GPRS or UMTS in the park.
“Few devices can do this at present, but the idea was to look into the future and at what mobile devices will eventually be able to do,” explains Cathal ORiordan, a technical researcher at TSSG. “The trials showed that the OSS can determine and provide the best network connection available in a users location.”
The AlbatrOSS project also demonstrated other services, including authorisation, user profiling and billing, and the aggregation of 3G services, such as integrating location awareness with a mapping system to provide accurate directions. Another trial focused on smart home systems, allowing users to access their home network remotely to control security systems or even domestic appliances.
“There are many problems remaining that impede the roll-out of 3G,” Ryan says. “However, the results of the project will help operators, service providers and others support 3G networks and services when they are rolled out.”
The project manager notes that many elements of the AlbatrOSS architecture will be used commercially, particularly those components covering service roaming, mediation, billing, and process and location management.
