Method of seamless vertical handover for sdr terminal and sca based sdr terminal for the same

Abstract

The present invention provides a method of seamless vertical handover for an SDR terminal and an SCA based SDR terminal for the same. A method of seamless vertical handover for an SDR terminal of the present invention includes: determining whether a download of a waveform application related to a peripheral access network is needed by collecting peripheral access network information prior to requesting vertical handover; if it is determined that the download is needed, downloading and storing the waveform application; and performing the seamless vertical handover using the pre-stored waveform application upon request the vertical handover. Therefore, the seamless vertical handover for the SDR terminal can be efficiently performed.
