A system and method for timely maintaining or establishing an R-P connection after a mobile station roams from the control of an old base station controller to that of a new BSC is provided. According to the prior art programs of said kind were written in a separate development environment and subsequently the developed algorithm was re-implemented using a programming language available for the process control system and the associated compiler. The notification routing module may detect a notification that is directed to at least one of the cellular communication devices, determine which cellular communication device is active within the group of cellular communication devices to which the notification is directed, and route the notification to the active cellular communication device.
