摘要

The invention refers to the processing method of mobile communication and the method and device for transferring a telephone from one station to another through a wireless communication system (handoff),That is to say, from a CDMA code partition multi access system (using an experimental Senal) to a system based on alternative access technology. Add a simple test box circuit, even a basic boundary line. Border base station is a base station, which only operates in the field of entrance technology, and its coverage is adjacent to that of Basel station and CDM station. Simulated seiner's mobile monitor from border base stationSimilarly, it monitors pilots at base stations operating in CDMA. Once the mobile forces find pilots related to the base station system, it will notify the system control department according to the standard operation. The system controller realized that the main seiner was equivalent to D and baseAs a result, he responded by launching a hard handoff process into the system, based on alternative entry techniques. The border base station uses a twice time technology for fine tuning and synchronization from the CDMA base station adjacent to the base station.Estimation of absolute time from system
