Abstract
Communications systems and methods for controlling transportation of data. The methods commonly include entering state information associated with a data transportation connection in a state information record maintained in a data processing entity. The data transportation connection is normally established between user equipment and a node, commonly via a gateway node, and the data processing entity is typically configured to control transportation of data based on the state information table. The methods also usually include, detecting that the data transportation connection is deactivated for the user equipment, sending information from the gateway node that the user equipment cannot be reached, and, in response to the information, deleting the state information from the state information record. The systems generally allow for implementation of the methods.
