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).
