A system and method for facilitating communications between a mobile device and a network application are provided. A mobile device transmits a request for data change information that includes a time out interval. The network application receives the request and measures a time elapsed since the receipt of the data change request. The network application transmits notification to the mobile device client that the time out interval has elapsed or a network specified time out occurs. As notifications are received or a network time out is detected, the mobile client device tunes the time out interval for subsequent data change requests.
