Abstract

A method comprising running an application on user equipment; providing a mobility service; using a packet switched connection when said mobility service is unavailable; and using said mobility service when said mobility service becomes available.

Claims

1. (canceled)

2. A method, comprising:

executing an application at user equipment, the executing comprising accessing an Internet Protocol (IP) network via a first access using a first IP address maintained by a home point-of-attachment, with communications to the user equipment via the first IP address routed from the home point-of-attachment to a foreign point-of-attachment in communication with the user equipment;

responsive to loss of the home point-of-attachment, notifying the application of said loss;

then continuing the executing of the application, the continued execution comprising accessing the IP network via the first access using a second IP address;

responsive to restoration of the home point-of-attachment, notifying the application of said restoration; and

then continuing the executing of the application, the continued execution comprising accessing the IP network via the first access using an IP address maintained by the home point-of-attachment, with communications to the user equipment being routed from the home point-of-attachment to a foreign point-of-attachment in communication with the user equipment.

3. The method of claim 2, wherein the step of continuing the executing of the application further comprises:

responsive to loss of availability of the first access, accessing the IP network via a second access.

4. The method of claim 3, wherein the first access is wireless local area network (WLAN) and the second access is general packet radio service (GPRS).

5. The method of claim 3, wherein the first access is GPRS and the second access is WLAN.

6. The method of claim 2, further comprising:

during the accessing of the IP network using a second IP address, periodically trying to reconnect to the home point-of-attachment.

7. The method of claim 2, wherein the step of executing the application at the user equipment further comprises:

using a Mobile IP mobility service to access the IP network via the first access using the first IP address maintained by the home point-of-attachment;

wherein the home point-of-attachment is a home agent under the Mobile IP mobility service and the foreign point-of-attachment is a foreign agent under the Mobile IP mobility service.

8. The method of claim 2 wherein each of the home point-of-attachment and the foreign point-of-attachment is a VPN gateway under the Moblke standard.

9. A user equipment apparatus configured to:

execute an application at user equipment to access an Internet Protocol (IP) network via a first access using a first IP address maintained by a home point-of-attachment, with communications to the user equipment via the first IP address routed from the home point-of-attachment to a foreign point-of-attachment in communication with the user equipment;

responsive to loss of the home point-of-attachment, notify the application of said loss;

then cause the application to access the IP network via the first access using a second IP address;

responsive to restoration of the home point-of-attachment, notify the application of said restoration; and

then cause the application to access the IP network via the first access using an IP address maintained by the home point-of-attachment, with communications to the user equipment being routed from the home point-of-attachment to a foreign point-of-attachment in communication with the user equipment.

10. The apparatus of claim 9, wherein the apparatus is further configured to:

following the notifying of the application of said loss and responsive to loss of availability of the first access, accessing the IP network via a second access.

11. The apparatus of claim 10, wherein the first access is wireless local area network (WLAN) and the second access is general packet radio service (GPRS).

12. The apparatus of claim 10, wherein the first access is GPRS and the second access is WLAN.

13. The apparatus of claim 9, wherein the apparatus is further configured to:

during the accessing of the IP network using a second IP address, periodically try to reconnect to the home point-of-attachment.

14. The apparatus of claim 9, wherein the executing of the application also uses a Mobile IP mobility service to access the IP network via the first access using the first IP address maintained by the home point-of-attachment.
