METHOD FOR CONSERVING RESOURCES DURING WIRELESS HANDOVER OF A MULTI-MODE MOBILE DEVICE

摘要

A method is described that is for handing over a multi-mode mobile device from a first network technology to a second network technology. The method includes initiating by the multi-mode mobile device a first packet session in a first wireless network and detecting by a multi-mode mobile device a second wireless network supporting a different access network technology. The method also includes determining a Quality of Service requirement and completing pre-registration session establishment procedures for a second session in the second wireless network when the first session includes at least one of a QoS sensitive service and real time service by the first wireless network and mobile device and after completion of the pre-registration session establishment procedures the multi-mode mobile device receives service from the first wireless network and remains dormant on the second wireless network.
