Method and system for maintaining a wireless data connection
First Claim
1. A method in a mobile device, the method comprising:
- making an attempt to initiate a data connection with a wireless network;
if the attempt is not successful, setting a timer to a first time period and making a another attempt to initiate a data connection with the wireless network after the first time period expires;
if the other attempt is not successful, setting the timer to a second time period greater than the first time period, and making a subsequent attempt after the second time period expires;
and if the subsequent attempt is successful, initiating a service check timer and checking a status of the data connection upon expiry of the service check timer.

Abstract
A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.
