  • METHOD AND APPARATUS FOR PERFORMING A HANDOVER IN AN EVOLVED UNIVERSAL TERRESTRIAL RADIO ACCESS NETWORK
    Publication number: 20150201356
    Abstract: A method and an apparatus for performing a handover in an evolved universal terrestrial radio access network (E-UTRAN) are disclosed. A wireless transmit/receive unit (WTRU) sends a measurement report to a source evolved Node B (eNB), and receives a handover command from the source eNB. The WTRU initiates reception and processing of a primary broadcast channel (P-BCH) at the target cell after receiving the handover command. The WTRU then sends a random access preamble to the target eNB, receives a random access response from the target eNB, and sends a handover complete message to the target eNB. The reception and processing of the P-BCH may be initiated immediately after receiving the handover command or after sending the handover complete message. The WTRU may apply default configuration or source cell configuration in the target cell until a target cell SFN and/or P-BCH information are acquired.

  • BALANCING PAGING LOAD AND TRACKING AREA UPDATES
    Publication number: 20150195761
    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 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. A current mobility state of the WTRU is determined and a predetermined metric of the WTRU 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.
