Abstract

A procedure when a mobile station apparatus accesses a CSG cell in which it is unregistered is defined and a procedure based on the definition is performed. A small base station apparatus applied to a mobile communication system, receives a originated call request message including a user identifier and priority information from a camping mobile station apparatus, determines whether or not to permit the originated call request of the mobile station apparatus, based on the user identifier and the priority information, and transmits the determination result to the mobile station apparatus. In addition, the small base station apparatus permits the originated call request, if the user identifier included in the originated call request message of the mobile station apparatus indicates that the mobile station apparatus is registered.

Claims

1-16. -16. (canceled)

17. A base station apparatus wirelessly connected to a mobile station apparatus, which

releases wireless connection, based on mobile station apparatus information of said mobile station apparatus being wirelessly connected, and

transmits, to said mobile station apparatus, a wireless connection release message instructing release of wireless connection, said message having set therein, as access destination cell information for causing another preferable cell to start an initial access procedure,

cell ID information and frequency information for specifying said preferable cell, and

broadcast information applied to said preferable cell.

18. The base station apparatus according to claim 17, wherein said base station apparatus is an access-restricted, small base station apparatus, and determines whether or not to transmit said wireless connection release message, based on a user identifier and priority information included in a originated call request from said mobile station apparatus.

19. A mobile station apparatus wirelessly connected to a base station apparatus, which

upon receiving, from said base station apparatus being wirelessly connected, a wireless connection release message instructing release of wireless connection, said message having set therein, as access destination cell information for causing another preferable cell to start an initial access procedure,

cell ID information and frequency information for specifying said preferable cell, and

broadcast information applied to said preferable cell,

applies said broadcast information to a cell specified by said cell ID information and frequency information, and starts an initial access procedure, after release of wireless connection.

20. A mobile communication system comprising a mobile station apparatus wirelessly connected to a base station apparatus, wherein

said base station apparatus transmits, based on mobile station apparatus information of said wirelessly connected mobile station apparatus, a wireless connection release message instructing release of wireless connection, said message having set therein, as access destination cell information for releasing wireless connection and causing another preferable cell to start an initial access procedure,

cell ID information and frequency information for specifying said preferable cell, and

broadcast information applied to said preferable cell, and

said mobile station apparatus applies, upon receiving said wireless connection release message from said base station being wirelessly connected, said broadcast information to a cell specified by said cell ID information and frequency information, and starts an initial access procedure, after release of wireless connection.

21. The mobile communication system according to claim 20, wherein said base station apparatus is an access-restricted, small base station apparatus, and determines whether or not to transmit said wireless connection release message, based on a user identifier and priority information included in a originated call request from said mobile station apparatus.
