Abstract: Applications which required real-time communications like mobile clouds, augmented reality, and voice over IP (VoIP) have significantly increased, and therefore the need to support seamless connectivity across overlaid heterogeneous networks are becoming more and more important. Handover interruptions (HI) may occur when mobile users move from the long-term evolution (LTE) to wireless local area network (WLAN) (or from WLAN to LTE) during active real-time applications. This paper analyses vertical handover (VHO) schemes and VHO procedures based on 3GPP for confirming interruption time.

Keywords: vertical handover; VHO; handover interruption; wireless local area network; WLAN; long-term evolution; LTE.
