APPARATUS AND METHOD FOR TIMER AND COUNTER SETTING IN MOBILE COMMUNICATION SYSTEM

摘要

A timer and a counter setting-up apparatus and a method thereof in a mobile communications system for shortening a time for processing a protocol signaling element in a video call are provided to improve the connection success ratio of video call connection by applying a timer and a dynamic counter based on a round time delay. A calling terminal and a receiving terminal start a signaling procedure clarified in a protocol for a VT(Video Telephony)(310). A timer and a counter value are renewed by measuring RSS(Radio Signaling Strength) and RTD(Round Trip Delay)(315). The signaling message switching procedure is completed based on the updated timer and counter value. The level of the terminal is determined in a mobile level detection process. A master/slave terminal is determined in a master/slave determination process.
