Method and system for supporting an evolved UTRAN

摘要

A method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. 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 receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi-RAT capability information including the E-UTRAN capability to the UTRAN. 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 measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

1. An integrated circuit, comprising:
circuitry configured to generate a first message indicating multi-mode/multi-RAT capability information, wherein the multi-mode/multi-RAT capability information includes an indication of support for evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (UTRAN) (E-UTRAN) and support for handover associated with UTRAN and E-UTRAN; circuitry configured to output the first message to a transmitter for transmission to a UTRAN base station via a first UTRAN channel: circuitry configured to receive, from a receiver, a handover message from the UTRAN base station via a second UTRAN channel; circuitry configured to extract first information associated with an E-UTRAN from the handover message, the first information indicating a frequency band and a bandwidth associated with handover to the E-UTRAN; and circuitry configured to handover to the E-UTRAN based on the handover message.
