METHOD OF SAVING RESOURCES DURING WIRELESS COMMUNICATION HANDOVER OF MULTI-MODE MOBILE DEVICE Russian patent published in 2015 - IPC H04L12/70 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to handover between technologies for multi-mode mobile devices and is designed for handover of 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 in an area of multi-technology wireless coverage and detecting by a multi-mode mobile device a second wireless network supporting a different access network technology than the first wireless network; determining a quality of service requirement for services supported by the session, and completing initial network entry and session establishment procedures by the multi-mode mobile device 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 not completing initial network entry and session establishment procedures by the multi-mode mobile device when no QoS sensitive service and real time services are supported by the mobile device and first wireless network.

EFFECT: high throughput.
