HANDOVER METHOD BASED ON SEAMLESS MOBILITY CONDITIONS

摘要

Methods and apparatus for determining if seamless handover is required for mobile device network connections are disclosed. In one such method, a mobile device establishes connectivity to a public data network (“PDN”) via a cellular network, determines the availability of a plurality of wireless local area networks (“WLANs”), at least one member of the plurality of WLANs providing connectivity to the PDN via the cellular network, and determines if a condition requiring seamless handover is present. If the condition requiring seamless handover is present, then the mobile device selects, from the plurality of WLANs, a trusted WLAN as the handover WLAN, the trusted WLAN being a WLAN that provides connectivity to the PDN via the cellular network.

1. A method for providing connectivity handover for a mobile device from a cellular network to a handover wireless local area network (“WLAN”), the method comprising:
establishing connectivity to a public data network (“PDN”) via the cellular network; determining availability of one or more WLANs; determining if a condition requiring seamless handover is present, the condition requiring seamless handover being associated with the mobile device; determining if at least one of the one or more WLANs is a trusted WLAN, the trusted WLAN providing seamless handover to the PDN via the cellular network; and connecting to the trusted WLAN; wherein if a condition requiring seamless handover is present and if at least one of the one or more WLANs is a trusted WLAN, selecting a trusted WLAN as a handover WLAN and requesting connectivity to the PDN via the cellular network during an authentication with the handover WLAN, otherwise, selecting any one of the one or more WLANs as the handover WLAN.
