Abstract

A portable communications device (PCD) is coupled to a first network by way of a second network. The PCD is normally in radio communication with the first network, and is coupled to the first network by way of the second network when the PCD is out of radio communication with the first network. In particular, the PCD is coupled to the second network, and is caused to leave a first network mode and enter a second network mode. A network connection is established with the first network by way of the second network, and communication with the first network is entered into by way of the second network.

Claims

1. A method for accessing data applications resident on a first network by way of a second network, comprising:

coupling a device to the first network, the first network including data applications and services for use by the device, the device in radio communication with the first network, wherein the device is operable to receive pages;

automatically sensing coupling of the device to the second network, leaving a first network mode and entering a second network mode by a first operational portion of the device;

automatically establishing a network connection between the device and the first network via the second network by a second operational portion of the device; and

automatically entering into communication between the device and the first network by way of the second network by a third operational portion of the device.

2. The method of claim 1, wherein the device comprises a video camera.

3. The method of claim 1, wherein the second network is a packet switched network.

4. The method of claim 1, wherein the device comprises a video screen.

5. The method of claim 1, wherein the device comprises a microphone and a speaker.

6. The method of claim 1, wherein the device comprises a cellular transceiver whereby the device maintains radio communication with at least one of the first and second network.

7. The method for accessing data applications of claim 1 wherein the device is coupled to the second network via a dedicated based station.

8. The method of claim 7 wherein the dedicated base station communicates via a wired connection with the second network.

9. The method of claim 1 further comprising determining that the device is out of communication with the first network.

10. The method of claim 1 further comprising determining that the communication between the device and the first network is degraded.

11. A computer readable medium containing instructions that perform acts to access data applications resident on a first network by way of a second network, comprising:

coupling a device to the first network, the first network including data applications and services for use by the device, the device in radio communication with the first network, wherein the device is operable to receive pages;

automatically sensing coupling of the device to the second network, leaving a first network mode and entering a second network mode by a first operational portion of the device;

automatically establishing a network connection between the device and the first network via the second network by a second operational portion of the device; and

automatically entering into communication between the device and the first network by way of the second network by a third operational portion of the device.

12. The computer readable medium of claim 11, wherein the device comprises a video camera.

13. The computer readable medium of claim 11, wherein the device comprises a still camera.

14. The computer readable medium of claim 11, wherein the device is operable to receive web pages.

15. The computer readable medium of claim 11, wherein the device comprises a microphone and a speaker.

16. The computer readable medium of claim 11, wherein the device comprises a cellular transceiver whereby the device maintains radio communication with at least one of the first and second network.

17. The computer readable medium of claim 11, wherein the first network is a cellular telephone network and the second network is a digital network.

18. The computer readable medium of claim 11 wherein the device is coupled to the second network via a dedicated based station.

19. The computer readable medium of claim 18 wherein the dedicated base station communicates via a wired connection with the second network.

20. The computer readable medium of claim 11 further comprising determining that the device is out of communication with the first network.
