STATUS TRANSITION TIMER SETTING SYSTEM, MOBILE COMMUNICATION SYSTEM, AND STATUS TRANSITION TIMER SETTING METHOD

摘要

The objective of the invention is to improve the communication quality by optimizing the resource use amounts in a mobile communication network. A status transition timer setting system, which determines a status transition timer related to a time in which the status of a mobile apparatus (4) performing a mobile communication transitions from a communication state to an idle state in a mobile communication system (1) including a core network (2N) and a radio access network (3N), comprises: a core resource use amount acquiring unit (31) that acquires a core resource use amount that is a resource use amount of the core network (2N); a radio resource use amount acquiring unit (33) that acquires a radio resource use amount that is a resource use amount of the radio access network (3N); a timer determining unit (34) that determines the status transition timer on the basis of the acquired core resource use amount and radio resource use amount; and a timer setting unit (42) that sets the determined status transition timer to the mobile apparatus (4).
