Interworking of networks with single radio handover
First Claim
Patent Images
1. A method for interworking of networks, comprising:
- receiving signals from an access point (AP) in a first network;
investigating the signals to identify a service set identifier (SSID);
determining, using the SSID, whether the AP supports interworking of networks to access a second network using the first network; and
associating with the first network to access the second network using a Wireless Fidelity (WiFi) interworking function (WIF) element, wherein the WIF element comprises a singling forwarding function (SFF), and a mobile internet protocol (IP) foreign agent (FA), and wherein to access the second network includes using the mobile IP FA to tunnel from the first network to the second network.

8. A method for network entry, comprising:
-
receiving a first signal from a first network using a station (STA) configured to communicate over the first network and a second network; establishing association with the first network; authenticating the STA in the second network by sending extensible authentication protocol (EAP) messages to a WiFi Interworking Function (WIF) through an access point (AP) enabling single radio handoff from the first network to the second network via a singling forwarding function (SFF) in the WIF; transmitting a dynamic host configuration protocol (DHCP) discovery message to discover a DHCP server; receiving a DHCP Offer message; responding to the DHCP Offer message with a DHCP Request message; receiving an acknowledgement from the WIF element; and transmitting data over the second network using the first network via a mobile internet protocol (IP) foreign agent (FA) in the WIF. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An article comprising a tangible machine readable medium that stores a program, the program being executable by a machine to perform a method, comprising:
-
receiving signals from an access point (AP) in a first network; investigating the signals to identify a service set identifier (SSID); determining, using the SSID, whether the AP supports interworking of networks to access a second network using the first network; and associating with the first network to access the second network using a Wireless Fidelity (WiFi) interworking function (WIF) element, wherein the WIF element comprises a singling forwarding function (SFF), and a mobile internet protocol (IP) foreign agent (FA), and wherein to access the second network includes using the mobile IP FA to tunnel from the first network to the second network. - View Dependent Claims (16, 17)
