Abstract
A system and method for monitoring the activity of a mobile subscriber in a GSM-based PLMN system from an Intelligent Network (IN) telecommunications system comprising several Intelligent Peripherals (IPs) connected to a Service Control Point (SCP) over a network. The detailed technique is automatically initiated when the Service Control Point (SCP) of an IN system attempts to reach a mobile subscriber and fails. In the first phase, the SCP arms an SMS-IP using a dummy SMS message. Upon the detection of renewed subscriber activity of a mobile subscriber who was previously inactive or unreachable, a PLMN triggering notification is generated. In this second phase, the PLMN transmits an alert to the SMS-IP which in turn notifies the SCP.
