Abstract

Methods and apparatus in a wireless device for use in maintaining appropriate authentication credentials for receiving a message service provided by a service network which is external to a wireless network are described. The wireless device receives, via the wireless network, a data session configuration file which includes a list of a plurality of wireless networks mapped against authentication credentials associated with each said wireless network. The list includes authentication credentials associated with the wireless network. The wireless device submits, via the wireless network, the authentication credentials for establishing a data session via the wireless network. Then, the wireless device receives, in the data session via the wireless network, the message service provided by the service network. Prior to receiving the file, the wireless device may maintain default authentication credentials associated with a default wireless network, submit via the default wireless network the default authentication credentials for establishing a data session via the default wireless network, and receive in the data session via the default wireless network the message service provided by the service network.

Claims

1. A method in a wireless portable communication device for use in accessing a common data application with a service network which is external to a plurality of wireless networks, the method comprising:

maintaining default authentication credentials associated with a default wireless network;

submitting, via the default wireless network, the default authentication credentials for establishing a data session via the default wireless network;

accessing, in the data session via the default wireless network, the common data application with the service network which is external to the default wireless network;

receiving a data session configuration file which includes a list of a plurality of wireless networks mapped against current authentication credentials associated with each said wireless network, the list including current authentication credentials which are different for each said wireless network;

communicating with a current one the wireless networks for registration;

selecting, from the list, one of the current authentication credentials that is associated with the current wireless network;

submitting, via the current wireless network, the current authentication credentials for establishing a data session via the current wireless network; and

accessing, in the data session via the current wireless network, the common data application with the service network which is external to the current wireless network.

2. The method of claim 1, wherein the act of receiving the data session configuration file is responsive to g change in subscription for the wireless portable communication device.

3. The method of claim 1, wherein the default wireless network comprises a default cellular network and the current wireless network comprises a current cellular network.

4. The method of claim 1, wherein the data session comprises one of a Packet Data Protocol (PDP) context or a Point-to-Point Protocol (PPP) session.

5. The method of claim 1, further comprising:

transmitting, via the default or current wireless network, a request for receiving the data session configuration file; and

receiving, via the default or current wireless network, the data session configuration file in response to transmitting the request.

6. The method of claim 1, further comprising:

receiving the data session configuration file upon registration in the current wireless network.

7. The method of claim 1, further comprising:

roaming from the default wireless network to the current wireless network; and

receiving the data session configuration file upon roaming onto the current wireless network.

8. The method of claim 1, wherein the common data application comprises an e-mail messaging application.

9. The method of claim 1, further comprising:

roaming on the current wireless network; and

selecting the current authentication credentials in the list which is associated with the current wireless network that is being roamed on.

10. A wireless portable communication device configured to communicate in a wireless network for accessing a common data application with a service network which is external to the wireless network, the wireless portable communication device comprising:

a receiver;

a transmitter;

a memory;

the memory being configured to save default authentication credentials associated with a default wireless network;

the transmitter being configured to transmit, via the default wireless network, the default authentication credentials for establishing a data session via the default wireless network;

the receiver and the transmitter being further configured to access, in the data session via the default wireless network, the common data application with the service network which is external to the default wireless network;

a the receiver being further configured to receive a data session configuration file;

the memory being further configured to save the data session configuration file, the data session configuration file including a list of a plurality of wireless networks mapped against current authentication credentials associated with each said wireless network, the list including current authentication credentials which are different for each said wireless network;

the receiver and the transmitter being further configured to communicate with a current one the wireless networks for registration;

the transmitter being further configured to transmit, via the current wireless network, current authentication credentials selected from the list and associated with the current wireless network, for establishing a data session via the current wireless network; and

the receiver and the transmitter being further configured to access, in the data session via the current wireless network, the common data application with the service network which is external to the current wireless network.

11. The wireless portable communication device of claim 10, wherein the receiver is further configured to receive the data session configuration file responsive to a change in subscription for the wireless portable communication device.

12. The wireless portable communication device of claim 10, wherein the default wireless network comprises a default cellular network and the current wireless network comprises a current cellular network.

13. The wireless portable communication device of claim 10, wherein the data session comprises one of a Packet Data Protocol (PDP) context or a Point-to-Point Protocol (PPP) session.

14. The wireless portable communication device of claim 10, further comprising:

the transmitter being further configured to transmit via the default or the current wireless network, a request for receiving the data session configuration file; and

the receiver being further configured to receive via the default or the current wireless network, the data session configuration file in response to transmitting the request.

15. The wireless portable communication device of claim 10, further comprising:

the receiver being further configured to receive the data session configuration file upon registration in the current wireless network.

16. The wireless portable communication device of claim 10, which is configured to roam from the default wireless network to the current wireless network, and further comprising:

the receiver being further configured to receive the data session configuration file upon roaming on the current wireless network.

17. The wireless portable communication device of claim 10, wherein the common data application comprises an e-mail messaging application.

18. The wireless portable communication device of claim 10, which is configured to roam on the current wireless network and select the current authentication credentials in the list associated with the current wireless network that is being roamed on.
