The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate compared to a 4G communication system such as an LTE. According to an embodiment of the present invention, a method performed by a terminal in a wireless communication system comprises the steps of: identifying, by a first processor of the terminal, a state of the terminal; transmitting the state of the terminal to a second processor of the terminal; identifying an electric power-related parameter associated with the state of the terminal; and transmitting, to a base station, a terminal message including the electric power-related parameter.
