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.

-
a back off timer for timing a back off period;
a service check timer for timing a service check period; and
a connection manager for determining a data connection to the wireless network is established at expiry of the service check timer, for resetting the service check timer upon its expiry if a connection is established, for transmitting connection requests to the wireless network upon initialisation, upon expiry of the back off timer and upon determination that the established data connection has been lost, and for resetting the back off timer in response to receipt of a connection rejection from the wireless network. - View Dependent Claims (22, 23, 24, 25)
