VERTICAL HANDOVER BETWEEN DIFFERENT NETWORK TECHNOLOGIES SUCCESFULLY DEMONSTRATED
Helsinki, Finland, 5 November - The Wi-Fi HotZone company Radionet, together with Ericsson, TeliaSonera Finland, and Helsinki University of Technology, has demonstrated the first vertical handover in commercial networks i.e. seamlessly switching between different network connections all the while an application is running. The demonstration was carried out in WLAN, LAN and Telia Sonera Finland's commercial GPRS networks and marks first such demonstration in a commercial network.
The demonstration is a part of the VHO ("Vertical HandOver") research project, in which Ericsson, Radionet, TeliaSonera Finland and the Product Modelling & Realization Group of Helsinki University of Technology have joined their forces to study the interoperability between different types of networks. The project belongs to the NETS technology programme of TEKES, National Technology Agency of Finland.
The demonstration showed how consumers would benefit from the integration of different network technologies and intelligent applications, which are capable of adapting to different networks.
"We believe that in the future, users will be able to choose from different network technologies. Seamlessly handing connection over from one network to the other will be one of the key challenges. What we achieved today by demonstrating switching between commercial cellular, WLAN and LAN networks all the while an application is running, constitutes the first step in solving that challenge," says Radionet CTO Max Björkgren.
During the past few months, the integration of different network technologies has been advancing rapidly. However, global mobility and the co-operation between different players still present great challenges. The VHO project is addressing these challenges by evaluating the usefulness and usability of new research innovations in commercial networks. The first tests in commercial networks mark an important milestone towards the goal of commercially available heterogeneous networks.
Key to the demonstration, the SIMA-concept (Simultaneous Multiple Access), developed by Ericsson Research in Finland, enables handover from a one network to another. Helsinki University of Technology, together with Ericsson Finland, has developed the applications and interfaces used in the Vertical Handover project. The integration of WLAN-technologies to third generation mobile networks is one the main technical targets of the project, and Radionet's know-how plays the crucial role in reaching this target.
