Espoo, Finland – As a significant milestone in its fixed-mobile convergence strategy, Nokia has completed both voice and data calls with Unlicensed Mobile Access (UMA) technology in a Nokia Solutions Experience Center in the United States.
UMA, a 3GPP (3rd Generation Partnership Program) standard, is an access technology that allows seamless handover of mobile voice and data from a cellular network to a wireless local area network (WLAN/WiFi). The UMA standard defines how mobile operators can turn home, office and public WLANs into seamless extensions of their cellular networks. With UMA, operators can deliver voice and data services to subscribers over the WiFi access networks, dramatically increasing mobile service usage while decreasing costs of network deployment.
The voice calls were conducted from a live cellular network to WLAN and from WLAN to cellular. In addition, a data call was conducted from cellular to WLAN. Both voice and data calls were completed using a Nokia test phone.
“This milestone is an excellent example of Nokia’s unique ability to offer service providers with true end-to-end solutions, from our industry-leading Release 4 core architecture to our devices equipped with both cellular and WLAN connectivity,” said Mark Louison, senior vice president, Networks, North America, Nokia. “UMA is poised to open up a number of new opportunities and choices for operators and their end-users. We’re one step closer to simplifying the end-user mobile experience to access voice, personal information, and multimedia services on one device irrespective of their location, whether at work, at home, or on the go.”
Nokia’s UMA network solution is part of its end-to-end Fixed-Mobile Convergence solution that offers fixed, mobile and hybrid operators a smooth evolution from today’s networks to the next-generation networks of tomorrow.

Notes to the editor
Unlicensed Mobile Access (UMA) technology is one of the two alternative access technologies for cellular/WiFi convergence. Based on the 3GPP Generic Access Network standard (known as TS 43.318), UMA technology enables access to mobile voice, data and IMS services over IP broadband access and unlicensed spectrum technologies. By deploying UMA technology, service providers can enable subscribers to roam and handover between cellular networks and public and private unlicensed wireless networks using dual-mode mobile handsets. With UMA, subscribers receive a consistent user experience for their mobile voice, data and IMS services as they transition between networks.
The other access technology option is called Native IP Access. Native IP Access is packet-based and refers to accessing VoIP telephony and IP multimedia services using IMS and Session Initiation Protocol (SIP) for the network signaling. Nokia supports both alternatives.
The UMA specifications were originally created by Nokia and Kineto Wireless, with Alcatel, AT&T Wireless, British Telecom, Cingular, Ericsson, Motorola, Nortel, O2, Research in Motion, Rogers Wireless, Siemens, Sony-Ericsson and T-Mobile US. The specifications are available for downloading at www.umatechnology.org. The UMA technology specification, known as TS 43.318 in the 3rd Generation Partnership Program (3GPP) standards body, was recently approved for inclusion into the upcoming 3GPP Release 6.
