Timing design method between digital mobile communication system device and each subsystem

摘要

A master clock of a mobile communication system that provides voice or data services using a code division multiple access (CDMA) system is defined as a GPS clock provided by a global positioning system (GPS). Each GPS The present invention relates to a digital mobile communication system apparatus and a timing design method between subsystems for redesigning an interface and a timing between a system and an exchange so that accurate timing schedules are achieved. In a CDMA system using a CDMA switching center (MSC) In order to maintain the frequency and time synchronization between the two systems, each subsystem is designed based on the clock provided by the GPS, and the hardware connection between the systems is designed based on the clock,
