Abstract: A METHOD FOR ASSIGNING A TRACKING AREA (TA) IS DISCLOSED. A MOBILITY STATE OF A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) IS DETERMINED AND THE TA IS ASSIGNED BASED ON THE DETERMINED MOBILITY STATE. ALSO DISCLOSED IS A METHOD FOR ACCESSING A CLOSED SUBSCRIBER GROUP (CSG) TA. A CSG TA IDENTIFIER IS RECEIVED AT A WTRU (600) AND IS STORED. A CSG TA BROADCAST IS RECEIVED AND THE BROADCAST CSG TA IS ACCESSED IF AN IDENTIFIER OF THE BROADCAST CSG TA MATCHES THE STORED CSG TA IDENTIFIER. ALSO DISCLOSED IS A METHOD FOR CHANGING A MOBILITY STATE OF A WTRU (600). A CURRENT MOBILITY STATE OF THE WTRU (600) IS DETERMINED AND A PREDETERMINED METRIC OF THE WTRU (600) IS EXAMINED. THE PREDETERMINED METRIC IS EVALUATED TO DETERMINE IF THE METRIC HAS CROSSED A THRESHOLD AND THE MOBILITY STATE IS CHANGED BASED ON THE EVALUATED METRIC.
