ALWAYS-ON WIRELESS INTERNET PROTOCOL COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide a system and method for an always-on wireless IP communication.

SOLUTION: An access provider network (APN) that includes an always-on packet data serving node (PDSN) may be used to communicate over a wireless communication link with a mobile station. The PDSN may include an inactivity timer and may be used to set the inactivity timer to an inactivity timer starting value and send a starting value estimate to the mobile station over the wireless communication link. The starting value estimate may be used to receive an inactivity timer estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN.
