Apparatus, system and method of securing communications of a user equipment (ue) in a wireless local area network

A User Equipment (UE) comprising:

• a Wireless Local Area Network (WLAN) transceiver;
• a cellular transceiver to communicate with an evolved Node B (eNB) of a cellular network;
• and
• a controller to determine a UE security key based on a cellular security key corresponding to the eNB, and to establish a connection with a WLAN access device based on the UE security key.

An evolved Node B (eNB) comprising:

• a cellular transceiver to communicate with a User Equipment (UE) via a cellular link;
• a controller to determine a UE security key based on a cellular security key corresponding to the eNB;
• and
• an access device interface to send to a Wireless Local Area Network (WLAN) access device security information corresponding to the UE, the security information including a WLAN identifier of the UE and the UE security key.

A Wireless Local Area Network (WLAN) access device comprising:

• a WLAN transceiver;
• a cellular manager interface to receive from a cellular manager a WLAN identifier of a User Equipment (UE), and an indication that communication with the UE is to be performed at an unassociated and unauthenticated state;
• and
• a controller to cause the WLAN transceiver to communicate packets via an unassociated and unauthenticated link between the WLAN transceiver and the UE, the packets encapsulating communications between the cellular manager and the UE.

A User Equipment (UE) comprising:

• a Wireless Local Area Network (WLAN) transceiver;
• a cellular transceiver to receive a UE verification key from an evolved Node B (eNB) of a cellular network;
• and
• a controller to establish a WLAN-based link between the UE and the eNB via an associated and unauthenticated WLAN link between the UE and a WLAN access device, and to send the UE verification key to the eNB via the WLAN-based link.
