Abstract

A mobile station apparatus receives an indication and access restriction information, where the indication indicating whether the cell is a Closed Subscriber Group (CSG) cell, where the CSG cell configured to restrict an access of the mobile station apparatus that are not being registered, and where the access restriction information indicating an access restriction related to an emergency call. The mobile station apparatus also transmits a connection request message for the emergency call based on the access restriction information, where the cell on which the mobile station apparatus camped being the CSG cell and where the mobile station apparatus not registering the cell.

Claims

1. A mobile station apparatus including a processor that communicates with a base station apparatus by using a cell, the mobile station apparatus comprising:

receiving circuitry that receives an indication and one type of at least two types of access restriction information,

the indication indicating whether the cell is a Closed Subscriber Group (CSG) cell,

the CSG cell configured to restrict an access of the mobile station apparatus that is not being registered,

a first type, of the at least two types of access restriction information, indicating an access restriction related to a normal call but not an emergency call, and

a second type, of the at least two types of access restriction information, indicating an access restriction related to the emergency call but not the normal call; and

transmitting circuitry that (i) transmits a connection request message, in a case for the emergency call, to the base station apparatus based on the second type of the at least two types of access restriction information and (ii) transmits a connection request message, in a case for the normal call, to the base station apparatus based on the first type of the at least two types of access restriction information.

5. The mobile station apparatus of claim 1, further comprising:

measuring circuitry that measures a CSG cell and selects, as an access destination cell, the CSG cell with a higher priority than a macro cell, in a case that the CSG cell allows an access of the mobile station apparatus.

2. A base station apparatus including a processor that communicates with a mobile station apparatus by using a cell, the base station apparatus comprising:

transmitting circuitry that transmits an indication and one type of at least two types of access restriction information,

the indication indicating whether the cell is a Closed Subscriber Group (CSG) cell,

the CSG cell configured to restrict an access of the mobile station apparatus that is not being registered,

a first type of the at least two types of access restriction information, indicating an access restriction related to a normal call but not an emergency call, and

a second type of the at least two types of access restriction information, indicating an access restriction related to the emergency call but not the normal call; and

receiving circuitry that (i) receives a connection request message, in a case for the emergency call, that is transmitted from the mobile station apparatus based on the second of the at least two types of access restriction information and (ii) receives a connection request message, in a case for the normal call, that is transmitted from the mobile station apparatus based on the first type of the at least two types of access restriction information.

3. A processing method performed in a mobile station apparatus including a processor that communicates with a base station apparatus by using a cell, the processing method comprising:

receiving an indication and one type of at least two types of access restriction information,

the indication indicating whether the cell is a Closed Subscriber Group (CSG) cell,

the CSG cell configured to restrict an access of the mobile station apparatus that are not being registered,

a first type of the at least two types of access restriction information, indicating an access restriction related to a normal call but not an emergency call, and

a second type of the at least two types of access restriction information, indicating an access restriction related to the emergency call but not the normal call;

transmitting a connection request message, in a case for the emergency call, to the base station apparatus based on the second type of the at least two types of access restriction information, and

transmitting a connection request message, in a case for the normal call, to the base station apparatus based on the first type of the at least two types of access restriction information.

6. The processing method of claim 3, further comprising:

measuring a CSG cell and selecting, as an access destination cell, the CSG cell with a higher priority than a macro cell, in a case that the CSG cell allows an access of the mobile station apparatus.

4. A processing method performed in a base station apparatus including a processor that communicates with a mobile station apparatus by using a cell, the processing method comprising:

transmitting an indication and one type of at least two types of access restriction information,

the indication indicating whether the cell is a Closed Subscriber Group (CSG) cell,

the CSG cell configured to restrict an access of the mobile station apparatus that is not being registered,

a first type of the at least two types of access restriction information, indicating an access restriction related to a normal call but not an emergency call, and

a second type of the at least two types of access restriction information, indicating an access restriction related to the emergency call but not the normal call;

receiving a connection request message, in a case for the emergency call, that is transmitted from the mobile station apparatus based on the second type of the at least two types of access restriction information, and

receiving a connection request message, in a case for the normal call, that is transmitted from the mobile station apparatus based on the first type of the at least two types of access restriction information.
