Abstract
In one embodiment, a mobile station (1) is capable of performing location registration procedures with first and second mobile management units (31 and 32) that respectively correspond to first and second RANs (Radio Access Networks). Further, the mobile station (1) supports ISR (Idle mode Signalling reduction) for reducing location registration procedures caused by reselection between the first RAN (21) and the second RAN (22). Furthermore, the mobile station (1) is configured to deactivate ISR in the mobile station (1) when voice service configuration information stored in the mobile station (1) is updated when the ISR is activated.
