Infineon and Kineto Wireless have demonstrated several IMS-based applications using UMA technology to show the seamless handover between mobile and Wi-Fi access networks.

and

, a supplier of Unlicensed Mobile Access (UMA) technology, have combined two technologies that will facilitate the rapid delivery of mobile and fixed Internet Protocol Multimedia Subsystem (IMS) services across a broadband Wi-Fi access network.

The companies demonstrated several IMS-based applications using UMA technology to show the seamless handover between mobile and Wi-Fi access networks.

IMS is the open, standardised IP multimedia and telephony core network specification for mobile and fixed operators that is defined by 3GPP (3rd Generation Partnership Project).

UMA is the 3GPP global standard for Mobile/Wi-Fi convergence that enables mobile subscribers to roam and handover between cellular networks and WLANs using multi-mode mobile handsets.

The demonstration consisted of Infineon’s IMS client for mobile phones, operating with Kinteo’s UMA client on a GSM/GPRS/EDGE-WiFi handset platform. The demonstration showed how UMA provides session continuity of IMS-based presence and push-to-talk applications when the handset platform passed between a live GPRS network and Wi-Fi connection.
