Alcatel-Lucent and LG Complete Live Handoff Between LTE and CDMA Networks

Published on: 1st Jan 1970: 1:33am

Alcatel-Lucent and LG say that they have completed a successful handoff of an end-to-end data call between LTE and CDMA mobile networks. ­The live, over-the-air handover involved an uninterrupted streaming video session conducted during test drives in the New York metropolitan area over Alcatel-Lucent's LTE and CDMA/EV-DO infrastructure using an LG Electronics CDMA/LTE dual mode device.

These tests are part of Alcatel-Lucent's ongoing effort to ensure that the LTE networks of service providers such as Verizon Wireless interact smoothly and seamlessly with existing 2G and 3G CDMA networks in order for the user to experience uninterrupted service.

For the tests, Alcatel-Lucent employed its end-to-end LTE solution, which is comprised of base stations (eNodeBs), Evolved Packet Core (EPC), IP Multimedia Subsystem (IMS), IP backhaul solutions and associated management systems. The tests also demonstrated a feature on CDMA/EV-DO networks called Evolved High Rate Packet Data (eHRPD), which serves as an interface to manage the seamless handover of data services between the two network types.

LG's M13 CDMA/LTE device incorporated for testing was created with commercial grade components and will form the basis for a consumer device which is expected to be available in 2010. The M13 also achieved recognition from the Federal Communications Commission (FCC) and fully supports both CDMA EV-DO and LTE.

"LG is committed to advancing the commercialization of 4G and was excited to be involved in the successful interoperability test between CDMA and LTE," said In-kyung Kim, vice president of 4G development at LG Electronics Mobile Communications Company R&D Center. "LG's M13 terminal will be a key device to enable CDMA network operators to deploy a LTE network incrementally over a national CDMA network."
