Alcatel-Lucent and LGE Completed Data Call Handoff Between LTE and CDMA

Alcatel-Lucent and LG Electronics (LGE) completed a 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 end-to-end commercial LTE and CDMA/EV-DO infrastructure using an LG Electronics CDMA/LTE dual mode device.


"This is a key milestone that demonstrates Alcatel-Lucent's readiness to deliver LTE to CDMA operators," said Ken Wirth, president, 4G/LTE Networks, Alcatel-Lucent.


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. In 2009, Alcatel-Lucent's eHRPD offering received the CDMA Development Group (CDG) Network Technology Innovation award for its leadership role in the development of the eHRPD standard and its successful introduction into service provider networks.


This test initiative also leveraged professional services expertise including project management and planning, as well as installation, commissioning, integration and test plan execution services.


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.


Alcatel-Lucent said these successful tests are part of its 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.
