Abstract

A combination cellular and Wi-Fi hardware device has an IP interface that is configured to communicate with a first cellular network, a Wi-Fi network, or both. The combination cellular and Wi-Fi hardware device is configured to provide the network functionality (e.g., virtualized network cloud) that is required to facilitate communication and data flow between the IP interface and either a second cellular network or a cloud computing infrastructure network. The IF interface is accessed using a single IP address by a mobile device in wireless communication with the combination cellular and Wi-Fi hardware device. The single IP address is maintained when the mobile device switches between using the first cellular network and the Wi-Fi network to communicate with the combination cellular and Wi-Fi hardware device, and vice versa.

Claims

1. A combination cellular and Wi-Fi hardware device, comprising:

an IP interface configured for communication with a first cellular network, a Wi-Fi network, or both;

the combination cellular and Wi-Fi hardware device providing network functionality required to facilitate communication and data flow between the IP interface and either a second cellular network, or a cloud computing infrastructure network;

wherein the IP interface is accessed using a single IP address by a mobile device in wireless communication with the combination cellular and Wi-Fi hardware device; and

wherein the single IP address is maintained when the mobile device switches between utilizing the first cellular network and the Wi-Fi network to communicate with the combination cellular and Wi-Fi hardware device, and vice versa.

2. The combination cellular and Wi-Fi hardware device of claim 1, wherein the first cellular network is a long term evolution (LTE) radio access network (RAN).

3. The combination cellular and Wi-Fi hardware device of claim 1, wherein the first cellular network is provided by an evolved NodeB antenna.

4. The combination cellular and Wi-Fi hardware device of claim 1, wherein the IP interface comprises an interworking function module configured to direct and interwork communication from the first cellular network to a cellular and Wi-Fi control plane module of the IP interface.

5. The combination cellular and Wi-Fi hardware device of claim 4, wherein the cellular and Wi-Fi control plane module is a generic IP signaling protocol module configured to assign the single IP address to the mobile device.

6. The combination cellular and Wi-Fi hardware device of claim 4, wherein the IP interface comprises a wireless application gateway (WAG) manager module in communication with the interworking function module.

7. The combination cellular and Wi-Fi hardware device of claim 1, wherein the IP interface comprises a cellular and Wi-Fi control plane module configured to receive communication from the Wi-Fi network.

8. The combination cellular and Wi-Fi hardware device of claim 1, wherein the mobile device utilizes the first cellular network and the Wi-Fi network concurrently to facilitate communication and data flow between the combination cellular and Wi-Fi hardware device and the mobile device.

9. The combination cellular and Wi-Fi hardware device of claim 8, wherein the first cellular network comprises an LTE-Advanced protocol network.

11. The combination cellular and Wi-Fi hardware device of claim 1, wherein the cloud computing infrastructure network comprises an Internet provider network.

12. The combination cellular and Wi-Fi hardware device of claim 1, wherein switching between utilizing the first cellular network and the Wi-Fi network occurs at about 50 microseconds or less.

13. The combination cellular and Wi-Fi hardware device of claim 1, wherein the IP interface comprises an authenticating module that authenticates the single IP address of the mobile device such that when the mobile device switches between utilizing the first cellular network and the Wi-Fi network, or vice versa, no additional authentication is required.

14. The combination cellular and Wi-Fi hardware device of claim 1, wherein the IP interface comprises a fast path module configured to provide a common fast path for communication and data flow along both the first cellular network and the Wi-Fi network.

15. The combination cellular and Wi-Fi hardware device of claim 1 further comprising one or more of virtualized network modules that provide the network functionality of a mobility management entity (MME), a serving gateway (S-GW), a trusted wireless access gateway (T-WAG), a packet data network gateway (P-GW), a traffic detection function (TDF), a authentication, authorization, and accounting protocol (AAA) server, a home subscriber server (HSS), a policy and charging rules function (PCRF) server, an online charging server (OCS), and a charging gateway function (CFG) server.

16. A computer implemented method of using a combination cellular and Wi-Fi hardware device to provide for communication and data flow with a mobile device, comprising:
