Abstract
A method of handling data sessions between user devices in a network is disclosed. The method includes receiving at a first network element an indication of non-delivery of a short message service message directed to a user device. Next, an insert subscriber data request message is sent to a second network element, wherein the insert subscriber data request message includes a flag that informs the second network element of the non-delivery of the short message service message and requests that the second network element notify the first network element when the user device is reachable. The first network element receives an insert subscriber data request answer from the second network element.
