METHOD AND APPARATUS FOR HANDOVER DECISION BY USING CONTEXT INFORMATION IN MOBILE COMMUNICATIONS NETWORK

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for a handover decision by which various services suitable for user's preferences can be provided by deciding not only the point of time of a handover considering only a signal strength but also the point of time of a handover using information from a terminal and networks, in a 4G network in which heterogeneous networks coexist.

SOLUTION: A method for deciding a handover of a mobile terminal using context information in a network environment includes: receiving context information from the terminal and networks; evaluating selection priorities of network interfaces for each transmission path for each application program based on the context information; and obtaining a handover decision value for selecting a network interface for each transmission path by applying a cost function to the evaluated selection priority.
