Abstract: A method for expedited tunnel establishment with a non-Third Generation Partnership Project (3GPP) interworking gateway to access a 3GPP network is provided. A User Equipment (UE) initiates establishment of an Internet Protocol secure (IPsec) tunnel with a first non-3GPP interworking gateway associated with the 3GPP network. The UE probes availability of a second non-3GPP interworking gateway associated with the 3GPP network before the IPsec tunnel with the first non-3GPP interworking gateway is established successfully. The UE initiates establishment of an IPsec tunnel with the second non-3GPP interworking gateway in response to failing to establish the IPsec tunnel with the first non-3GPP interworking gateway and the second non-3GPP interworking gateway being available. The UE accesses the 3GPP network over the IPsec tunnel with the second non-3GPP interworking gateway.

Abstract: A method for performing Internet reachability management and associated apparatus are provided. The method may include: establishing, by a processor of the UE, a first connection to a first access device; receiving, by the processor, an indicator complying with a first protocol sent from the first access device; in response to receiving the indicator, performing, by the processor, a reachability detection complying with a second protocol to generate a detection result; and in response to the detection result representing that a network is not reachable, performing at least one of: displaying, by a display of the UE, a message or icon to represent the first connection or the network is unavailable; disconnecting, by the processor, the first connection; and establishing, by the processor, a second connection to a second access device.
