RANGING APPARATUS AND METHOD IN WIRELESS MOBILE COMMUNICATION SYSTEM

摘要

A ranging apparatus and a method in a wireless mobile communication system for reducing a time for ranging are provided to perform ranging quickly by defining new standard value in wireless mobile communications system. A base station and a code base ranging are completed. A ranging request message after code base ranging completion is transmitted to the base station(102). If a response about the ranging request message is not received, the first count value is increased by 1(108). A code base ranging is requested in case of increased first count value is less than 1. The first count value with 1 is increased by 1.
