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