Method and system for maintaining a wireless data connection
First Claim
1. A method of automatically maintaining a data connection on a wireless data network, comprising:
- determining, at minimum fixed time intervals determined by a service check timer, the status of a previously established data connection;
automatically transmitting a connection request if the previously established data connection is determined to be lost; and
re-establishing the previously established data connection if the transmitted connection request is accepted by the wireless data network.

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.

20. A mobile device for establishing and maintaining a data connection to a wireless data network, the mobile device comprising:
-
a back off timer for timing a back off period between retries to establish the data connection; a service check timer for setting a minimum fixed interval after which a previously established data connection is checked to determine if it has been lost; and a connection manager for determining if the previously established data connection between the mobile device and the wireless network exists or has been lost;
for resetting the service check timer upon its expiry if the data connection exists;
for transmitting connection requests to the wireless network upon initialization, upon expiry of the back off timer, and upon expiry of the service check timer if the previously 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 (21, 22, 23, 24, 25)
