System and method for subscriber activity supervision

In a method for indicating actively of an initially-inactive mobile subscriber operable in a PLMN (Public Land Mobile Network) system, an improvement of a method for indicating at least a change in the activity of the mobile subscriber from an IN (Intelligent Network) telecommunications system comprising a plurality of IPs (Intelligent Peripherals) connected to an SCP (Service Control Point) over a network, the IN system coupled to the PLMN system, said method comprising the steps of:

• arming said PLMN system from said IN system to detect renewed activity by said mobile subscriber;
• sending a dummy SMS message from said IN system to said PLMN system;
• monitoring at least during selected periods, the activity status of said mobile subscriber in said PLMN system;
• transmitting an alert message from said PLMN system to said IN system when renewed activity of the mobile subscriber in said PLMN system is detected during said step of monitoring;
• and
• generating an internal notification within said IN system in response to the receipt of said alert message from said PLMN system to said IN system.

A method for indicating at least a change in activity status of a mobile subscriber operable in a PLMN (Public Land Mobile Network) system in conjunction with an IN (Intelligent Network) telecommunications system comprising a plurality of IPs (Intelligent Peripherals) connected to an SCP (Service Control Pooint) over a network, said IN system coupled to said PLMN system, comprising the steps of:

• arming said PLMN system from said IN system to detect renewed activity by said mobile subscriber, wherein said step of arming said PLMN system comprises the step of sending a dummy SMS (Short Message Service) message from said IN system to said PLMN system;
• monitoring, at least during selected periods, said activity status of said mobile subscriber in said PLMN system;
• transmitting an alert message from said PLMN system to said IN system when renewed activity by said mobile subscriber in said PLMN system is detected during said step of monitoring;
• and
• generating an internal notification within said IN system in response to receipt of said alert message at said IN system from said PLMN system.

In an IN (Intelligent Network) telecommunications system and a PLMN (Public Land Mobile Network) system, said IN system comprising a plurality of IPs (Intelligent Peripherals) connected to an SCP (Service Control Point) over a network, said IN system being further connected to said PLMN system, a system for monitoring the activity status of a mobile subscriber in said PLMN system, said system comprising:

• means for determining an initial activity status of said mobile subscriber in said PLMN system;
• means for remotely arming said PLMN system from said IN system to detect renewed activity by said mobile subscriber responsive to a determination that said mobile subscriber is presently inactive, wherein said means for remotely arming said PLMN system comprises means for sending a dummy SMS (Short Message Service) message from said IN system to said PLMN system;
• means for at least intermittently monitoring said activity status of said mobile subscriber in said PLMN system;
• means for triggering and transmitting an alert message from said PLMN system to said IN system when renewed activity by said mobile subscriber in said PLMN system is detected;
• and
• means for generating an internal notification within said IN system in response to receipt of said alert message at said IN system from said PLMN system.
