Wireless communication method and apparatus for performing home Node-B identification and access restriction
First Claim
1. An evolved NodeB (eNodeB) comprising a receiver, transmitter and a processor, wherein:
- the transmitter is configured to transmit;
a message from a cell, the message including a closed subscriber group (CSG) identifier (ID) and at least one indicator, one of the at least one indicator being an indication that the cell is a CSG cell; and
signaling from a network, the signaling including a plurality of allowed CSG IDs; and
the processor and receiver are configured to;
receive, 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 an evolved NodeB (eNodeB), the method comprising:
-
transmitting a system information message from a cell, wherein the system information message includes a closed subscriber group (CSG) indication and a CSG identifier (CSG ID), wherein the CSG indication indicates the cell is a CSG cell, and wherein the CSG ID identifies the CSG; and receiving, from a wireless transmit/receive unit (WTRU), a request for access to the CSG cell pursuant to the CSG ID corresponding to at least one CSG the WTRU is configured to access. - View Dependent Claims (14, 15, 16, 17)
