Abstract
Embodiments of systems and methods for interworking of networks using a single radio handover are generally described herein. Other embodiments may be described and claimed.
Claims27
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.
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);
- 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.
A method for single radio handover, comprising:
- connecting to a first network using a single radio station (STA);
- detecting availability of a second network;
- discovering an address of a signal forwarding function (SFF) of the second network;
- establishing a tunnel to the SFF of the second network;
- performing initial entry to the second network over the tunnel;
- and
- performing handover to a base station in the second network.
A single radio station (STA) comprising a first protocol layer for communicating over a first network and a second protocol layer for communicating over a second network through the first network, wherein the STA is configured to receive signals from an access point (AP) in a first network, to investigate the signals to identify a service set identifier (SSID) to determine whether the AP supports interworking of networks, and to associate with the first network to access the second network using a Wireless Fidelity (WiFi) interworking function (WIF) element.
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.
