Abstract

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

Claims

1. A method of coupling a portable communications device (PCD) to a base station by way of a second network, the PCD normally in communication with the base station by way of a first network, the PCD being coupled to the base station by way of the second network when the PCD is out of communication with the base station by way of the first network, the method comprising:

coupling the PCD to the second network;

causing the PCD to leave a base station mode and enter a second network mode;

establishing a network connection with the base station by way of the second network; and

entering into communication with the base station by way of the second network.

2. The method of claim 1 further comprising:

coupling the PCD to the second network;

causing the PCD to leave an base station mode and enter a second network mode;

establishing a network connection with the base station by way of the second network; and

entering into communication with the base station by way of the second network.

3. The method of claim 2 wherein the PCD is a two-way electronic mail device, and wherein entering into communication comprises entering into two-way communication with the base station by way of the second network.

4. The method of claim 1 further comprising:

de-coupling the PCD from the second network upon ending communication therewith; and

causing the PCD to leave the second network mode and enter the base station mode.

5. The method of claim 4 wherein the PCD has a serial port, wherein coupling the PCD to the second network comprises:

placing the PCD into a cradle having a serial port connector and a network connector so that the serial port of the device is coupled with the serial port connector of the cradle; and

coupling the network connector of the cradle to the second network,and

wherein de-coupling the PCD from the second network comprises removing the PCD from the cradle.

6. The method of claim 1 wherein the PCD has a serial port, and wherein coupling the PCD to the second network comprises:

placing the PCD into a cradle having a serial port connector and a network connector so that the serial port of the PCD is coupled with the serial port connector of the cradle; and

coupling the network connector of the cradle to the second network.

7. The method of claim 1 wherein causing the PCD to enter the second network mode comprises causing the PCD to gain the attention of and establish control over a wireless network communications device.

8. The method of claim 7 wherein causing the PCD to enter the second network mode comprises causing the PCD to gain the attention of and establish control over a wireless network interface card.

9. The method of claim 1 wherein coupling the PCD to the second network comprises coupling the PCD to a public communications network.

10. The method of claim 1 wherein establishing the network connection comprises establishing a network connection with a base station by way of a public wireless communications network.

11. The method of claim 1 wherein entering into communication comprises entering into two-way communication with the base station by way of the second network to send and receive information.

12. A method of coupling a portable communications device (PCD) to a server network by way of a second network, the PCD normally in communication with the server network by way of a private communications network, the PCD having a serial port and being coupled to the server network by way of the second network when the PCD is out of communication with the server network by way of the private communications network, the method comprising:

placing the PCD into a cradle having a serial port connector and a network connector so that the serial port of the PCD is coupled with the serial port connector of the cradle;

coupling the network connector of the cradle to the second network;

causing the PCD to leave an server network mode and enter a second network mode;

establishing a network connection with the server network by way of the second network; and

entering into communication with the server network by way of the cradle and the second network.

13. The method of claim 12 for coupling a PCD to an server network by way of a second network, the PCD normally in communication with the server network by way of a private communications network, the PCD having a serial port and being coupled to the server network by way of the second network when the PCD is out of communication with the server network by way of the private communications network, the method comprising:

placing the PCD into a cradle having a serial port connector and a network connector so that the serial port of the PCD is coupled with the serial port connector of the cradle;

coupling the network connector of the cradle to the second network;

causing the PCD to leave an server network mode and enter a second network mode;

establishing a network connection with the server network by way of the second network; and

entering into communication with the server network by way of the second network.

14. The method of claim 13 wherein the PCD is a two-way wireless electronic mail device, and wherein entering into communication comprises entering into two-way communication with the server network by way of the second network.

15. The method of claim 12 further comprising:

de-coupling the PCD from the second network upon ending communication therewith; and

causing the PCD to leave the second network mode and enter the server network mode.

16. The method of claim 15 wherein de-coupling the PCD from the second network comprises removing the PCD from the cradle.

17. The method of claim 12 wherein causing the PCD to enter the second network mode comprises causing the PCD to gain the attention of and establish control over a PCD.

18. The method of claim 17 wherein causing the PCD to enter the second network mode comprises causing the PCD to gain the attention of and establish control over a member of a group consisting of a wireless modem and a wireless network interface card.

19. The method of claim 12 wherein coupling the network connector of the cradle to the network comprises coupling the network connector of the cradle to a public cellular communications network.

20. The method of claim 12 wherein entering into communication comprises entering into two-way communication with the server network by way of the second network to send and receive information.
