Wireless communication method and apparatus for performing home Node-B identification and access restriction
First Claim
1. A method, implemented in a node of a core network, for restricting access to a closed subscriber group (CSG), the method comprising:
- receiving a message including a request for access to the CSG, a CSG identifier (ID) that identifies the CSG and an identity of a wireless transmit/receive unit (WTRU);
determining whether to grant access to the CSG to the WTRU based on the CSG ID and subscriber policies associated to the identity of the WTRU; and
restricting access to the CSG based on the determination.

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.

19. A method for restricting access to a closed subscriber group (CSG), the method comprising:
-
transmitting a system information message from a cell, wherein the system information message includes a 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; receiving, at a home evolved Node-B (HeNB) controlling the cell, from a node of a core network, a list of identities of wireless transmit/receive units (WTRUs) allowed to access the CSG; maintaining the list of identities at the HeNB; receiving, at the HeNB, a message including a request for access to the CSG and an identity of a WTRU; and restricting access to the CSG to the WTRU based on the identity of the WTRU not being listed on the list of identities of the WTRUs allowed to access the CSG. - View Dependent Claims (20, 21, 22, 23, 24, 25)

26. A home evolved Node-B (HeNB) configured to control a cell, wherein:
-
the HeNB comprises a receiver, transmitter and a processor; the transmitter is configured to transmit a system information message from the 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; the receiver is configured to receive, from a node of a core network, a list of identities of wireless transmit/receive units (WTRUs) allowed to access the CSG; the processor is configured to maintain the list of identities at the HeNB; the receiver is configured to receive a message including a request for access to the CSG and an identity of a WTRU; and the processor in combination with the receiver and transmitter are configured to restrict access to the CSG to the WTRU based on the identity of the WTRU not being listed on the list of identities of the WTRUs allowed to access the CSG. - View Dependent Claims (27, 28, 29, 30, 31, 32)
