A mobile station, an access point, a gateway apparatus, a base station, and a handshake method thereof for use in a wireless network framework are provided. The wireless network framework comprises a first wireless network comprising the access point, and a second wireless network comprising the gateway apparatus and base station. There is an IP security tunnel between the access point and the gateway apparatus. When the mobile station handovers from the first wireless network to the second wireless network, it transmits a master session key to the gateway apparatus via the access point and the IP security tunnel. Additionally, when the mobile station handovers from the second wireless network to the first wireless network, it transmits a master session key to the access point. As a result, the authentication time, which is needed in handover procedure between the first wireless network and the second wireless network, is reduced effectively.

FIG. 1 is a schematic view of a wireless network framework according to a first embodiment of this invention;
FIG. 2 is a schematic view of a mobile station according to the first embodiment of this invention;
FIG. 3 is a schematic view of an access point according to the first embodiment of this invention;
In the following descriptions, the invention will be explained with reference to the embodiments thereof. However, the description of these embodiments is only for purposes of illustration rather than limitation. It should be noted that in the following embodiments and the attached drawings, elements unrelated to this invention are omitted from depiction; and dimensional relationships among individual elements in the attached drawings are illustrated only for ease of understanding and not for limiting the actual scale.
For purposes of description, all mobile stations set forth in the following embodiments are for use in a wireless network framework comprising a first wireless network and a second wireless network. The first wireless network is a WiFi wireless network based on the IEEE 802.11 standard, while the second wireless network is a WiMAX wireless network based on the IEEE 802.16 standard. Furthermore, an access point incorporated in the first wireless network is based on the IEEE 802.11 standard, while a gateway apparatus and a base station incorporated in the second wireless network are based on the IEEE 802.16 standard.
A first embodiment of this invention is depicted in FIG. 1, which is a schematic view of a mobile station 1 performing a handover over from the WiFi wireless network to the WiMAX wireless network. The WiFi wireless network comprises an access point 2, while the WiMAX wireless network comprises a base station 3 and a gateway apparatus 4. To explicitly define the environment in which this embodiment is implemented, it is assumed that the mobile station 1 has passed the authentication procedure of the WiFi wireless network and is now served by the access point 2 of the WiFi wireless network; the mobile station 1 stores an identification 1c of the mobile station 1 and a master session key 12 generated when the mobile station 1 is authenticated in the WiFi wireless network; and the mobile station 1 further generates an authorization key according to the master session key 12 and the identification 1c of the mobile station 1, all of which are based on the IEEE 802.11 standard and thus will not be further described herein. In addition, an Internet Protocol (IP) security tunnel 20 has been built between the access point 2 of the WiFi wireless network and the gateway apparatus 4 of the WiMAX wireless network according to the IP security encryption protocol, which may be accomplished by the prior art and thus will not be further described herein.
