1. A method comprising:receiving a Long Term Evolution (LTE) non-access stratum (NAS) message from a User Equipment (UE) device at a WiFi access point (AP) device operating in an environment without an LTE core network;
sending the LTE NAS message from the WiFi AP device using a control and provisioning of wireless access protocols (CAPWAP) tunnel to a wireless local area network (WLAN) controller;
translating, at the WLAN controller, the LTE NAS message to a WiFi service layer message;
receiving, using the CAPWAP tunnel, a NAS response based on the WiFi service layer message at the WiFi AP device from the WLAN controller; and
sending, from the WiFi AP device to the UE device, an LTE attach response based on the NAS response.
