Wireless communication method and apparatus for performing home node-B identification and access restriction
First Claim
1. A method for restricting access to a closed subscriber group (CSG), the method comprising:
- transmitting a message from a cell, the message including a CSG identifier (ID) and at least one indicator, and one of the at least one indicator including a CSG indication that the cell is a CSG cell;
transmitting signaling from a network via the cell, the signaling including a plurality of allowed CSG IDs; and
receiving, from a wireless transmit/receive unit (WTRU), a request for access to the CSG cell based on the at least one indicator and on the CSG ID being included in the list of allowed CSG IDs.

Abstract
A method and a wireless transmit/receive unit (WTRU), including a universal subscriber identity module (USIM), for identifying a closed subscriber group (CSG) cell are disclosed. The WTRU receives a broadcast from a cell including a cell identifier (ID). If the cell ID is associated with a CSG cell, the WTRU determines whether the CSG ID is programmed in the USIM. The cell broadcast may include a single bit information element (IE) indicating that the cell is a CSG cell. If the cell ID is a CSG ID, the cell ID may further include a plurality of fields which indicate at least one of a country, a region, an operator, and a home evolved Node-B (HeNB) number. The cell broadcast may further include a bit indicating whether the CSG cell is public or private. The cell broadcast may further include a bit indicating that emergency calls are allowed from all users.

13. A method implemented in a transmit/receive unit (WTRU), the method comprising:
-
reading system information from a cell; determining the cell is a closed subscriber group (CSG) cell based on the system information including a CSG indication that indicates the cell is a CSG cell; obtaining, from the system information, a CSG ID that identifies the CSG; determining that the CSG ID is not among a list of allowed CSG IDs maintained in a memory of the WTRU; determining that the CSG cell is an acceptable cell for reselection; adding the CSG ID to the list of allowed CSG IDs; and camping on the CSG cell. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A wireless transmit/receive unit (VVTRU) comprising:
-
a receiver configured to receive system information from a cell; and a processor configured to; determine the cell is a closed subscriber group (CSG) cell based on the system information including a CSG indication that indicates the cell is a CSG cell; obtain, from the system information, a CSG ID that identifies the CSG; determine that the CSG ID is not among a list of allowed CSG IDs maintained in a memory; determine that the CSG cell is an acceptable cell for reselection; add the CSG ID to the list of allowed CSG IDs; and instruct the receiver to camp on the CSG cell. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
