Abstract

La presente invención proporciona un método y un aparato para controlar la potencia de transmisión de un equipo de usuario, el método incluye: reducir un factor de ganancia de un primer tipo de canal del UE cuando la potencia de transmisión total de enlace ascendente del UE excede la potencia de transmisión máxima permitida; y determinar la potencia de transmisión total de enlace ascendente del UE, y si la potencia de transmisión total de enlace ascendente del UE excede la potencia de transmisión máxima permitida y el factor de ganancia del primer tipo de canal se reduce a un umbral de factor de ganancia predeterminado, reducir un factor de ganancia de un segundo tipo de canal del UE, de modo que la potencia de transmisión total de enlace ascendente del UE no exceda la potencia de transmisión máxima permitida. La presente invención reduce una frecuencia de caída de llamadas de servicio CS y garantiza la continuidad de las llamadas entre equipos de usuario.
