Abstract:
1. A method for providing user-apparent consistency in a wireless user device, comprising: assigning an IP address to a wireless user device in wireless communication with a wireless application server, the IP address associated with a communication session between the wireless user device and the wireless application server; retrieving user context information associated with the profile of a user of the wireless device from a remote store; storing the IP address and the user context information related to the communication session in an active session cache; maintaining the user context information in the active session cache during connectivity lapses between the wireless user device and the wireless application server such that the user context information does not need to be retrieved again from the remote store at reconnection; and allowing the wireless user device to rejoin the communication session, in the event the wireless communication is temporarily dropped and re-established between the wireless user device and the wireless application server, without losing the assignment of the IP address to the wireless user device or any information stored for the IP address in the active session cache; wherein the wireless user device rejoins the communication session implicitly from the user's perspective thereby providing an appearance of session continuity.
