METHOD AND APPARATUS FOR SELECTING OR RESELECTING HOME NODE-B (CLOSED SUBSCRIBER GROUP (CSG) CELL) AMONG CELLS HAVING COLLIDING PHYSICAL LAYER SIGNALS

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for selecting or reselecting an HNB (i.e., a CSG cell), among cells having colliding physical layer signals.SOLUTION: Once the ID of an HNB is determined, measurements needed to support cell selection or reselection are performed. A broadcast channel that broadcasts an HNB ID is detected and synchronized, and information obtained from the broadcast channel is forwarded to an NAS. The broadcasted HNB ID is checked against an HNB white-list provided by the NAS to determine whether the HNB is suitable for a WTRU. The WTRU selects the HNB to camp on, or changes from a cell currently serving the WTRU to the HNB if it is determined to be more suitable than the current serving cell.
