Patent Images
1. A method comprising:
- running an application on user equipment having mobility service functionality;
using the mobility service functionality of the user equipment to receive packets from a home agent of a mobility service, the mobility service allowing the user equipment to change point-of-attachment to the Internet without changing source IP address, the mobility service functionality allowing transparent network connection to the application;
determining that the home agent of the mobility service has become unavailable; and
in response to determining that the home agent of the mobility service has become unavailable, notifying the application of the need to change the source IP address and causing the application to inherit a destination network from the mobility service functionality.

5. A method comprising:
-
running an application on user equipment having mobility service functionality for receiving packets from a home agent of a mobility service, wherein the mobility service allows the user equipment to change point-of-attachment to the Internet without changing source IP address, the mobility service functionality allows transparent network connection to the application, and the application is notified of the need to change the source IP address when a home agent of the mobility service has become unavailable; determining that the home agent of the mobility service has become unavailable; periodically trying to reconnect to the home agent after the determining that the home agent has become unavailable; and in response to making a reconnection to the home agent, informing the application that mobility service is again available. - View Dependent Claims (6, 7, 8, 9, 10, 11)
