    摘要: A handover method in a plurality of wireless networks includes selecting one or more candidate networks from the plurality of wireless networks available to a mobile terminal of a user; calculating the latest connection time with a serving network currently serving the mobile terminal; deriving a history utility function based on the latest connection time; deriving system utility functions of the candidate networks in consideration of user and system environments; deriving selection functions for the candidate networks using the history utility function and the system utility functions; and selecting one of the candidate networks as a target network for handover using the selection functions. A target network for handover is selected using not only a system utility function reflecting user and system parameters but also a history utility function reflecting history information, thereby reducing the number of handovers and enhancing service quality.
