TeliaSonera Presents Easy WLAN Access With SIM Card Authentication.

STOCKHOLM, Sweden -- TeliaSonera has led a GSM Association project presenting how wireless LAN services can be combined with mobile access services in a very easy and user-friendly way. The project trial service is operational in Barcelona during the 3GSM World Congress, February 13-16.

SIM-card authentication enables seamless access to WLAN. The user can access WLAN networks without any usernames or passwords both in home networks and when roaming. International WLAN roaming works the same way as in GSM and 3G networks.

Seamless access is a key element in the converging world of different wireless networks and mobile services. This means that the user will be able to roam and switch between the different networks seamlessly and automatically, making it increasingly simple to use the growing number of mobile terminals with both mobile and WLAN access. The same easiness will be available to the user of any laptop computer with a data card, too.

"The trial is one step further into a more user-friendly and easy-to-use service environment where the user is always best connected and can fully concentrate on using the wanted service. The network access, be it 2G, 3G or WLAN, can be operated in the background. The aim is to make the technology automatic so that the user doesn't have to worry about it," says Veikko Hara, CTO, Corporate R&D, TeliaSonera AB.

The trial service is operational in Barcelona's Fira de Barcelona congress centre during the 3GSM World Congress. The WLAN network is provided by the Spanish WLAN operator Kubi Wireless and used by customers of six participating operator partners from Europe and Asia. The trial service is accessible with several commercially available terminals that support SIM authentication in WLAN access. In the trial, the SIM-card based authentication is routed through TeliaSonera's network.
