Abstract

A method and apparatus are provided that allow a wireless transmit / receive unit (WTRU) to search and add one or more closed subscriber group (CSG) identities (IDs) in the WTRU white list while in connected mode. Such method and apparatus include but are not limited to WTRU autonomous search or a manual search, WTRU initiated procedures, or network initiated procedures. Additionally, methods that allow the network and / or the non-access stratum (NAS) to add CSG IDs are also described.
