Abstract

Techniques in a wireless device for use in accessing a common data application with a service network which is external to a plurality of wireless networks are described. The device receives a data session configuration file which includes a list of the plurality of wireless networks mapped against authentication credentials associated with each wireless network. The device communicates with a current one the wireless networks. The device selects from the list one of the authentication credentials that is associated with the current wireless network. The device submits, via the current wireless network, the selected authentication credentials for establishing a packet data session via the current wireless network. The device then accesses, via the current wireless network using the packet data session, the common data application with the service network which is external to the current wireless network.

Claims

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

receiving a data session configuration file which includes a list of the plurality of wireless networks mapped against authentication credentials associated with each one of said wireless networks, each said authentication credentials specifying a bearer path for accessing the data service and being different for each one of said wireless networks;

in response to a change in subscription for the wireless portable communication device from a first wireless network to a second wireless network;

communicating with the second wireless network;

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

using the selected authentication credentials comprising the specified bearer path for establishing a data session via the second wireless network; and

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

2. The method of claim 1, further comprising:

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

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

3. The method of claim 1, further comprising:

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

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

4. The method of claim 1, further comprising:

roaming on the second wireless network; and

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

5. The method of claim 1, wherein the data session comprises a packet data session.

6. The method of claim 1 wherein the first and the second wireless networks comprise cellular telecommunication networks.

7. The method of claim 1, further comprising:

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

8. The method of claim 1, further comprising:

roaming from the first wireless network to the second wireless network.

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

10. The method of claim 1, wherein the authentication credentials specifying the bearer path for the data service comprises an Access Point Name (APN),

11. The method of claim 1, wherein the authentication credentials specifying the bearer path for the data service comprises a Network Access Identifier (NAI).

12. 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 a plurality of wireless networks, the wireless portable communication device comprising:

a receiver;

a transmitter;

a memory;

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

the memory being further configured to save the data session configuration the, the data session configuration file including a list of a plurality of wireless networks mapped against authentication credentials associated with each one of said wireless networks, each said authentication credentials specifying a bearer path for accessing the data service and being different for each one of said wireless networks;

in response to a change in subscription for the wireless portable communication device from a first wireless network to a second wireless network;

the receiver and the transmitter being further configured to communicate with the second wireless network;

the wireless portable communication device being further configured to select, from the list, one of said authentication credentials that is associated with the second wireless network;

the transmitter being further configured to transmit, via the second wireless network, the selected authentication credentials comprising the specified bearer path for establishing a data session via the second wireless network; and

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

13. The wireless portable core communication device of claim 12, further comprising:

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

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

14. The wireless portable communication device of claim 12, further comprising:

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

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

15. The wireless portable cornu unication device of claim 12, wherein the first and the second wireless networks comprise cellular telecommunication networks.

16. The wireless portable communication device of claim 12, further comprising:

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

17. The wireless portable communication device of claim 12, wherein the data session comprises a packet data session.

18. The wireless portable communication device of claim 12, wherein the common data application comprises an e-mail messaging application.

19. The wireless portable communication device of claim 12, which is configured to roam on the second wireless network and select the current authentication credentials in the list associated with the second wireless network that is being roamed on.

20. The wireless portable communication device of claim 12, wherein the authentication credentials specifying the bearer path for the data service comprises an Access Point Name (APN).
