APPARATUS AND A METHOD FOR OPTIMIZING RACH PREAMBLES/RESOURCES IN A MOBILE COMMUNICATION SYSTEM, CAPABLE OF SETTING AN RACH PARAMETER IN CONSIDERATION OF RACH COLLISION

摘要

PURPOSE: An apparatus and a method for optimizing RACH(Random Access Channel) preambles/resources in a mobile communication system are provided to efficiently allocate system resources related to a random access procedure, thereby increasing random access capacity.;CONSTITUTION: A terminal(401) transmits a preamble collision number and time information to a base station(403). The base station calculates collision probability statistic values of preambles. A network server(405) compares a predetermined target preamble collision probability value with the statistical value. The network server sets values of a random access preamble number and a resource related parameter. The base station transmits the random access preamble number and a value of the resource related parameter to the terminal through system information.;COPYRIGHT KIPO 2011
