Abstract
A method may be provided at a wireless terminal to support communications with a network node of a wireless communication network. An IKE SA may be initiated to establish a NAS connection between the wireless terminal and the network node through a non-3GPP access network and a non-3GPP interworking function network node. After initiating the IKE SA, an IKE authorization request may be transmitted through the non-3GPP access network to the N3IWF network node, with the IKE authorization request including an identifier of the wireless terminal. An access network key may be derived for the NAS connection through the non-3GPP access network at the wireless terminal, with the access network key being derived based on a NAS count for the wireless terminal and an anchor key. An IKE authorization response corresponding to the IKE authorization request may be received.
