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

摘要

the present invention performs an LTE tracking area update (TAU), a tracking area code, a wireless transmit receive unit (TAC), and PLMN-ID auxiliary optimization (WTRU) cell reselection. eNodeB is based at least in part by the broadcast system information includes at least one system information block (SIB) cast in E-UTRAN parameter response message sent by the EPC network. The WTRU compares the system information on the basis of creating a new TAC indicating the tracking area ID (TA-ID) of the new cell, the new and existing TAC TAC showing a TA-ID of the previous cell. The WTRU transmits a TAU request message including the TA-ID of a new cell to the EPC network. EPC network sends a TAU accept message or a TAU reject message to the WTRU.
