摘要： A bearer management device that performs control to reliably receive an incoming packet call that is made while a mobile terminal device is moving is provided. A bearer management device (10) includes an incoming call control unit (11) that, in the case where a mobility management device (30) manages a location of a mobile terminal device (40) as a result of movement of the mobile terminal device (40) whose location has been managed by a mobility management device (20), suspends processing of an incoming call to the mobile terminal device (40) made during movement of the mobile terminal device (40) until receiving a notification about completion of movement of the mobile terminal device (40) from the mobility management device (30), and resumes incoming call processing to the mobile terminal device (40) after receiving a notification about completion of movement of the mobile terminal device (40) from the mobility management device (30).

摘要： It is aimed to provide a mobility management device that can normally provide a UE with a notification of an incoming voice call made when ISR is activated and when a mobile communication device is moving from a location registration area under control of an MME to a location registration area under control of an SGSN. A mobility management device (10) makes an ISR feature operate in collaboration with an SGSN (20). It is assumed that a location registration area (60) managed by the mobility management device (10) exists within a location registration area (50) managed by the SGSN (20), and an incoming voice call is made to a mobile communication device (30) during when the mobile communication device (30) is moving out of the location registration area (60). The mobility management device (10) includes an incoming voice call control unit (11) that, in the above case, sends a response message indicating that the mobile communication device (30) is moving to a switching device (40) and, when an incoming voice call message is sent again from the switching device (40) to a switching device (40) after the lapse of a specified period of time, performs call attempt to the mobile communication device (30).

摘要： A communication system according to an exemplary embodiment of the invention includes an MME (25) that, by movement of a UE (45), performs Tracking Area Update processing that changes a location registration area of the UE (45) and manages the location registration area of the UE (45) before change, and a PGW (75) that sends, to the MME (25), a control signal required to be notified to the UE (45) during execution of the Tracking Area Update processing. When the MME (25) receives the control signal, it sends a response signal indicating that the Tracking Area Update processing is being executed to the PGW (75), and, after completion of the Tracking Area Update processing, the PGW (75) sends the control signal to an MME (35) that manages the location registration area of the UE (45) after change.
