Small base station apparatus, base station apparatus, mobile station apparatus, and mobile communication system
First Claim
1. A base station apparatus connected to a mobile station apparatus, the base station comprising:
- a releasing unit configured to release a connection to the mobile station apparatus being connected, anda transmitting unit configured to transmit, to the mobile station apparatus, a connection release message instructing release of the connection, the message including cell information for causing the mobile station apparatus to start an initial access procedure for another preferable cell,wherein the cell information includescell ID information and frequency information for specifying the preferable cell,broadcast information applied to the preferable cell detected by performing cell search, andpreamble information used for the initial access procedure on the preferable cell, and whereinthe broadcast information includes access restriction information,in a case where the access restriction information indicates an access restriction associated with Closed Subscriber Group (CSG) cell, andthe CSG cell is configured to restrict the access of the mobile station apparatus that are not being registered.

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.
