1. A method to handover a wireless communication device from a source communication network to a target non-Third Generation Partnership Project (non-3GPP) access node, the method comprising:
receiving, by a Network Exposure Function (NEF), device context for the wireless communication device from the source communication network;
detecting, by an Access and Mobility Management Function (AMF), when the wireless communication device attaches to the target non-3GPP access node, and in response, retrieving, by the AMF, the device context for the wireless communication device from the NEF; and
transferring, by the AMF, network signaling to serve the wireless communication device over the target non-3GPP access node based on the device context for the wireless communication device.
