METHOD AND SYSTEM FOR SUPPORTING EVOLVED UTRAN

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for supporting an evolved universal mobile telecommunication systems terrestrial radio access network (E-UTRAN).

SOLUTION: The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU sends multi-mode/multi-RAT capability information including a E-UTRAN capability to the UTRAN based on the received list. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs the measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN initiate a handoff to the E-UTRAN based on the measurement results.
