Title: MOBILE STATION, METHOD FOR CONTROLLING MOBILE STATION, MOBILE COMMUNICATION SYSTEM, MOBILE MANAGEMENT DEVICE, AND COMPUTER-READABLE MEDIUM
Abstract:
In one embodiment, a mobile station (1) is able to carry out location registration processing between first and second mobile management units (31 and 32) that respectively correspond to first and second radio access networks (RAN). In addition, the mobile station (1) supports idle mode signaling reduction (ISR) for reducing location registration processing that accompanies reselection between the first RAN (21) and the second RAN (22). Furthermore, the mobile station (1) is configured so as to deactivate ISR in the mobile station (1) if voice service setting information retained by the mobile station (1) is updated when ISR is activated.
