Wireless communication method and apparatus for performing home node-B identification and access restriction

摘要

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.

主权项

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.
