SYSTEM AND METHOD FOR SUBSCRIBER ACTIVITY SUPERVISION

摘要

A system and method for monitoring the activity of a mobile subscriber in a GSM-based PLMN system (1150) from an Intelligent Network (IN) telecommunications system comprising several Intelligent Peripherals (IPs) (1111-1114) connected to a Service Control Point (SCP) (1101) over a network. The detailed technique is automatically initiat ed when the Service Control Point (SCP) (1101) of an IN system attempts to reach a mobile subscriber and fails. In the first phase, the SCP (1101) arms an SMS-IP (1114) using a dummy SMS message (1181). Upon the detection of renewed subscriber activity of a mobile subscriber (1165) who was previously inactive or unreachable, a PLMN triggering notification is generated. In this second phase, the PLMN (1150) transmits an alert (1183) to the SMS-IP (1114) which in turn notifies the SCP (1101).
