VeriSign using the Tatara Mobile Services Control Platform to enable RADIUS and SIM-based
authentication and roaming between wireless networks
Tatara Systems, Inc., a developer of service delivery platforms for communications service providers, today announced that VeriSign (Nasdaq: VRSN), the leading provider of critical infrastructure services for the Internet and telecommunications networks, has selected and deployed the Tatara Mobile Services Control Platform to support its international wireless data roaming service (WDRS). WDRS promotes and provides seamless roaming for carriers looking to expand their next-generation offerings.
The operationally deployed WDRS combines existing and new technology to address interoperability between carrier networks and truly create a converged wireless data solution for VeriSign’s wireless carrier customers. Utilizing its breadth of heritage in communications, security and the Internet, VeriSign has created a cost-effective, transaction-based solution that handles not only interoperability, but billing, network usage mediation, and clearing and settlement.
Leveraging the capabilities of the Tatara Mobile Services Control Platform as a key foundation for WDRS, VeriSign allows its wireless and wireline carrier customers to more easily manage processes like authentication, service delivery and settlement with roaming partners. The Tatara Mobile Services Control Platform collects and distributes real-time authentication, authorisation and billing information and enforces deal term policies between roaming partners, thus supporting a component of VeriSign’s service. In addition, the Tatara Mobile Services Control Platform logs usage information centrally for inter-operator settlement and facilitates the maintenance and distribution of location, security, configuration and other network information – enabling VeriSign to support settlement between its wireless and wireline carrier customers and roaming partners.
VeriSign selected the Tatara Mobile Services Control Platform in part because it supports both RADIUS and SS7-based (SIM) authentication. Using the Tatara Mobile Services Control Platform, VeriSign can bridge the interoperability between RADIUS-based WLAN networks and SIM-based GSM networks to enable roaming using GSM-standard authentication and security. The Tatara platform enables subscriber authentication by passing information between a user’s SIM-enabled device connected to a WLAN network and the authentication data stored in the GSM network’s Home Location Register (HLR). Combining this capability with North America’s largest independent SS7 network, VeriSign can offer a turnkey wireless roaming solution to GSM operators. The Tatara platform and WDRS also support pure RADIUS-based roaming between networks for non-GSM operators or for customers without a SIM-enabled Wi-Fi device.
Armed with WDRS, carriers can now solve a variety of data roaming problems faced by end users who want to access wireless LAN and WAN networks as they travel. The solution will span technologies such as CDMA 1xRTT, CDMA EV-DO, GSM GPRS, UMTS and Wi-Fi.
Tatara Systems’ CEO Steve Nicolle said: “Tatara continues to lead the market in the area of integrating wireless LAN and WAN services into a common solution. Wireless users shouldn’t care about what network they’re on – only that they have the best available service and applications to meet their needs wherever they are. We’re pleased to have been selected by VeriSign. Their proven industry leadership as a trusted neutral party and stringent network requirements truly validates our platform. We look forward to working with them in pursuit of delivering on the promise of seamless global roaming across technologies.”
“Seamless roaming is one of the key issues that must be addressed in order for wireless data services to deliver on the huge potential they hold,” said Mark Lowenstein, managing director of Mobile Ecosystem and a leading expert on the wireless and mobile communications industry. “As mobile operators expand their coverage – both through domestic and international roaming agreements and through the integration of local and wide area wireless technologies – they will look for service offerings like WDRS to enable these arrangements.”
