METHOD AND APPARATUS FOR IMPLEMENTING TRACKING AREA UPDATE AND CELL RESELECTION IN A LONG TERM EVOLUTION SYSTEM

摘要

A wireless transmit/receive unit (WTRU) comprising a receiver configured to receive a tracking area code (TAC) from an evolved Node B (eNB), a processor configured to identify a tracking area of a new cell using the TAC, detect whether the identified tracking area matches one of a plurality of currently registered tracking areas, and generate a tracking area update (TAU) request message when the processor detects that the identified tracking area does not match one of the plurality of currently registered tracking areas and a transmitter configured to transmit the TAU request message the eNB
