Abstract:
1. A mobile station, comprising: a notification reception unit configured to receive notification in a first radio access network, the mobile station being configured to be capable of performing circuit switching communications using a circuit switching fallback function through a second radio access network that supports packet switching and circuit switching while the mobile station is in the first radio access network that supports the packet switching but does not support the circuit switching; and a barring processor unit configured to perform predetermined barring processing in the first radio access network based on information elements included in the notification, wherein the barring processor unit is configured to perform barring processing for origination of a circuit switching call from the mobile station using the circuit switching fallback function based on a first information element for barring an origination of a circuit switching call from the mobile station using the circuit switching fallback function and a second information element for barring an origination of a normal packet switching call from the mobile station among the information elements.
