## Abstract

A mobile station UE according to the present invention includes a notification reception unit 21 configured to receive an SIB2 in E-UTRAN and a barring processor unit 22 configured to perform predetermined barring processing in E-UTRAN based on information elements included in the SIB2. The barring processor unit 22 is configured to perform barring processing for origination of a CS call using a CSFB function based on “ac-BarringForCSFB-r10” and “ac-BarringForMO-Data” among the information elements.

## Claims

### Claim 1

A mobile station 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 a first radio access network that supports the packet switching but does not support the circuit switching, the mobile station comprising:
a notification reception unit configured to receive notification in the first radio access network; 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 using the circuit switching fallback function based on a first information element for barring an origination of a circuit switching call using the circuit switching fallback function and a second information element for barring an origination of a normal packet switching call among the information elements.

### Claim 2 (depends on 1)

The mobile station according to claim 1, wherein the barring processor unit is configured to perform barring processing for the origination of the circuit switching call using the circuit switching fallback function based on the first information element if the notification includes the first information element, and the barring processor unit is configured to perform barring processing for the origination of the circuit switching call using the circuit switching fallback function based on the second information element if the notification does not include the first information element but includes the second information element.

### Claim 3

(canceled)
