Abstract:
1. A Wi-Fi access point (Wi-Fi AP), comprising: a femtocell signaling interface; a wide area network (WAN) interface; a Wi-Fi access point radio access interface; and a controller sub-system, coupled to the femtocell signaling interface, the wide area network interface and the Wi-Fi AP radio access interface; wherein the controller sub-system performs a first connection establishment procedure with a user equipment through the femtocell signaling interface, and performs a second connection establishment procedure with a cellular core network (CN) through the wide area network interface; the controller sub-system performs a first security establishment procedure with the user equipment through the femtocell signaling interface, and performs a second security establishment procedure with the cellular core network by using the wide area network interface; the controller sub-system obtains a set of security parameters according to the first security establishment and the second security establishment; the controller sub-system further performs a first Wi-Fi bearer setup procedure and a second Wi-Fi bearer setup procedure with the user equipment and the cellular core network through the femtocell signaling interface and the wide area network interface, respectively; the controller sub-system performs a security information exchange procedure with the Wi-Fi access point radio access interface through the femtocell signaling interface; and the controller sub-system establishes a data transmission channel with the user equipment through the Wi-Fi access point radio access interface according to the set of security parameters.
