摘要

the present invention is to provide a management system that can travel even when a isr is active, to correctly identify an incoming voice call is generated during a mobile communication device from a position registration area controlled by a ms in a position registration area controlled by a sgsn.a management device (10) according to the displacement, this invention uses a function of isr in cooperation with a sgsn (20).based on the hypothesis that a position registration area (60) managed by a management device (10) travel is located in a position registration area (50) is managed by the sgsn (20) and an incoming voice call is sent to a mobile communications device (30) when the mobile communications device (30) from the second recording area of positio(60), a voice call control unit (11) in which the management device (10) transmits a travel switch (40), a response message indicating that the mobile communications device (30) moves, and when the switch (40) transmits the voice call (e) after a predetermined period of time ntrant.the incoming voice call control unit (11) processes calls to the mobile communications device (30).
