Method for measuring neighbor Access environment of mobile communication for handoff of connected mobile between asynchronous mobile communication and synchronous mobile communication mobile

摘要

The present invention detects a handoff event from the WCDMA network to the CDMA network, the base station controller to the mobile station informing a radio environment measurement events, to be measured in the WCDMA standard the DT message to the Iu interface RANAP protocol specified CDMA frequency band information and include the vicinity of a frequency measurement control message of the CDMA standards and transmits to the switching center to inform the measurement method, the switching center transmits to the mobile station to convert the DT messages received by transmission of the WCDMA standard SMS RP-DATA message of the message specified by the message between the switching center and the mobile station. Since the switching center receives the RP-DATA message including the vicinity of a frequency measurement response message from the mobile station, and transmits and converts the received message to a DT RP-DATA message, the base station controller is a frequency close to the MAHO measurement message indicating the wireless environment measurement by a control message of the RANAP protocol message to a DT and transferred to the central office. Convert the transmission to the mobile station switching center converts the DT message received by RP-DATA message, DT receives the message RP-DATA message including the vicinity of a frequency measurement report message from the mobile station, the transmission and the base station controller receives the transmitted determining a CDMA cell to hand off from the vicinity of a frequency measurement report message, and request a handoff to the central office.
