Abstract:
1. A method for deciding a handover of a mobile terminal based on context information for use in an environment with a plurality of networks, comprising: collecting 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 best network interface from among the networks by applying a cost function to the evaluated selection priority, wherein the selection priorities are evaluated by using the following formula: wherein Sij denotes an expectation value of an i-th application program when using a j-th network interface; Cij denotes a user's preference of j-th context information with respect to the i-th application program; and Rij denotes an influence of i-th context information in a j-th network.
