Abstract:
A network node (300) determines an expiration period of a timer (101) based on a predetermined parameter. The timer (101) is used to determine a transition from a CONNECTED state to an IDLE state of a mobile terminal (200) connected to a core network (20) through a radio access network (10). The predetermined parameter includes at least one of (a) a parameter regarding a frequency of connection of the mobile terminal (200) to the core network (20), (b) a parameter regarding a load on control signal processing by a mobility management node (300) arranged in the core network (20), (c) a parameter regarding a frequency of movement of the mobile terminal (200) between base stations (100), and (d) a parameter regarding software installed in the mobile terminal (200).
