Wireless communication method and apparatus for performing home Node-B identification and access restriction
First Claim
1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
- receiving signaling indicating a plurality of closed subscriber group (CSG) identifiers (IDs);
storing the plurality of CSG IDs;
receiving a system information message from a cell, the system information message including an ID and an indication that the cell is a CSG cell; and
on a condition that the ID included in the system information message is a CSG ID, determining whether the CSG ID matches one of the plurality of 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.

14. A wireless transmit/receive unit (WTRU) comprising:
-
a receiver configured to; receive signaling indicating a plurality of closed subscriber group (CSG) identifiers (IDs); and receive a system information message from a cell including an ID and an indication that the cell is a CSG cell; a memory device configured to store the plurality of CSG IDs; and a processor configured to, on a condition that the ID included in the system information message is a CSG ID, determine whether the CSG ID matches one of the plurality of CSG IDs stored in the memory device. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of selectively restricting wireless transmit/receive units (WTRUs) from accessing a closed subscriber group (CSG) cell, the method comprising:
-
the CSG cell transmitting a message including a 1-bit indicator indicating that the cell is either a public cell or a private cell;
whereinon a condition that the 1-bit indicator indicates that the CSG cell is a public cell, WTRUs that do not belong to a CSG may be allowed to access the CSG cell; and on a condition that the 1-bit indicator indicates that the CSG cell is a private cell, only WTRUs that belong to a CSG associated with the CSG cell can access the CSG cell.

30. A method of selectively restricting wireless transmit/receive units (WTRUs) from accessing a closed subscriber group (CSG) cell, the method comprising:
-
the CSG cell providing a first level of reselection criteria for WTRUs that are not associated with subscribed users; and the CSG cell providing a second level of reselection criteria for WTRUs that are associated with subscribed users.

-
31. A method of selectively restricting wireless transmit/receive units (WTRUs) from accessing a closed subscriber group (CSG) cell, the method comprising:
-
the CSG cell transmitting a message indicating the current capacity of the CSG cell; and on a condition that the message indicates that the CSG cell is currently running at full capacity, restricting services provided by the CSG cell to only WTRUs that are not associated with subscribed users.

-
32. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
-
maintaining a list of acceptable cells that can provide the WTRU with access to the emergency services; detecting a cell; determining that the detected cell is a CSG cell that provides services to a CSG that the WTRU is not a member of; adding the detected CSG cell to the list; and proceeding to camp on the CSG cell to access emergency services.

33. A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:
-
receiving a system information message from a cell, wherein the system information message includes; a closed subscriber group (CSG) indication that indicates that the cell is a CSG cell; and a CSG ID that identifies the CSG cell; and attempting to communicate with the CSG cell on a condition that the CSG ID is included in a list of allowed CSG cells stored in the WTRU. - View Dependent Claims (34, 35, 36, 37)
