    • PURPOSE: A handover message transmitting power control method and apparatus in a mobile communications system is provided to control a ranging code for ranging with a target BS(Base Station) and the transmitting power of a ranging request message according to calculated maximum transmitting power, thereby increasing the successive reception probability of the target BS. CONSTITUTION: An MS(Mobile Station) performs synchronization with a handover target BS(Base Station)(314). The MS calculates the maximum transmitting power of a handover ranging message through uplink information previously obtained. The MS transmits a CDMA(Code Division Multiple Access) ranging code to the target BS at a power level less than the calculated maximum transmitting power(316). The target BS station transmits a ranging response message or a CDMA assignment information element message to the MS(318). The target BS transmits a ranging response message including information about power control to the MS(322).
    • 目的:提供一种在移动通信系统中发送功率控制方法和装置的切换消息,以根据所计算的最大发送功率来控制用于与目标BS(基站)进行测距的测距码和测距请求消息的发射功率,从而 增加目标BS的连续接收概率。 构成:MS(移动站)与切换目标BS(基站)(314)执行同步。 MS通过先前获得的上行链路信息来计算切换测距消息的最大发射功率。 MS以小于计算出的最大发送功率的功率电平(316)向目标BS发送CDMA(码分多址)测距码。 目标BS站向MS发送测距响应消息或CDMA分配信息单元消息(318)。 目标BS向MS发送包括关于功率控制的信息的测距响应消息(322)。
