LTE Inter-technology Mobility (Enabling Mobility Between LTE and Other Access Technologies)


The Internet revolution and the wide availability of broadband access are creating a tremendous new appetite for mobile data services. Subscribers want the same Internet experience that they have at home, anytime, anywhere. Existing wireless access technologies such as HSPA and EVDO go part of the way in meeting this need; but spectral efficiency, cell-edge performance and high latency prevent them from providing the bandwidth, capacity and QoS to enable a true broadband service that is reasonably priced for subscribers and profitable for operators. While the data revenue is seeing a steady growth the data usage on current 3.5G network is exploding with reports of 6-25x growth year on year, fuelled by flat rate tariffs, better devices and USB dongles providing connection to laptops. In response to these dynamics, the wireless industry is anticipated to shift toward LTE and WiMAX technologies to be able to support cost effectively the capacity required for operators to accommodate mass market adoption of mobile data services.

This White-paper discusses inter-technology mobility functionality being defined for emerging broadband wireless technologies and explains how this new functionality will add value to operator’s networks. It explains the difference between various types of inter-technology mobility and then explores how LTE exploits inter-technology mobility to support a variety of access technologies including 3GPP legacy technologies as well as EVDO, WiFi and WiMAX. This paper also provides examples illustrating how to use inter-technology mobility to enhance existing services and provide new ones. Get Further insights from the white paper below;
