Abstract

This invention provides a system and method for splitting control and media content signals of a cellular network connection of a mobile station. A mobile station engages in a WAP browsing session with a cellular network connection over an air interface. As a user moves into coverage area of an access point, another browsing session is established between the mobile station and a non-cellular network connection. More specifically, the user'"'"'s WAP browsing session with a cellular network connection is upgraded to a Web browsing session with a non-cellular network connection. The present invention permits a user to control a Web browser on a remote device by providing user input to the mobile station. In particular, a media content portion of the cellular network connection is split and rerouted to the remote device, and a control portion of the cellular network connection is split and rerouted either via the non-cellular network connection or via the cellular network connection.

Claims

1. A method for splitting control and media content signals of a cellular network connection of a mobile station comprising the steps of:

determining a position of the mobile station relative to an access point;

determining a status of the mobile station when the mobile station is within a proximity of the access point;

authenticating the mobile station for access to a non-cellular network connection; and

splitting a media content portion from the cellular network connection and rerouting it to a remote device via the non-cellular network connection.

2. The method of claim 1, further comprising the step of splitting a control portion from the cellular network connection and rerouting it from the mobile station to the remote device via the non-cellular network connection.

3. The method of claim 1, further comprising the step of maintaining the cellular network connection to route a control signal from the mobile station to the remote device via the cellular network connection.

4. The method of claim 1, wherein the step of determining the position of the mobile station relative to the access point includes the step of utilizing at least one signal strength threshold to define at least one corresponding proximity of the mobile station relative to the access point.

5. The method of claim 1, further comprising the step of connecting the mobile station an access point that is physically closest to the mobile station relative to other access points.

6. The method of claim 1, wherein the non-cellular network connection is at least one of a Bluetooth connection, a Wi-Fi connection and an infrared connection.

7. The method of claim 1, wherein the remote device provides at least one of visual information and audio information.

8. A method for splitting control and media content signals of a cellular network connection of a mobile station comprising the steps of:

determining a position of the mobile station relative to an access point of a non-cellular network connection by measuring a signal strength of the mobile station by the access point;

requesting a status of the mobile station when the mobile station is engaged in a data session with the cellular network connection and is within a proximity of the access point;

receiving the status of the mobile station;

authenticating that the mobile station has permission to access a non-cellular network connections and services associated with the non-cellular network connection;

switching a connection of the mobile station from the cellular network connection to the non-cellular network connection;

assigning a communication link from the mobile station to a remote device; and

translating a user input generated at the mobile station into a signal that controls an action exhibited by the remote device.

9. A wireless communication system for switching network connections between at least one mobile station and a server, the system comprising:

a gateway being effective to send content data and receive control data;

a mobile station being effective to generate the control data and receive the content data;

a first network connected to the gateway and being capable of communicating with the mobile station via a first wireless link, the first network being effective to transfer the content data from the gateway to the mobile station and the control data from the mobile station to the gateway; and
