Method and apparatus for reducing electric power consumption of terminal in wireless communication system

A terminal in a wireless communication system, comprising:

• a display;
• a communication circuit;
• a processor, comprising processing circuitry, operatively connected with the communication circuit;
• and
• memory storing instructions which, when executed by the processor, cause the terminal to:
• receive, using the communication circuit, configuration information with respect to a 5G network communication from a base station;
• operate, using the communication circuit, the terminal in a first communication state based at least in part on the configuration information received from the base station to establish a connection of the 5G network communication for the terminal;
• and
• based at least in part on a user input received via a mode setting menu displayed on the display while the terminal is operated in the first communication state to change a power state of the terminal, operate, using the communication circuit, the terminal in a second communication state,
• wherein the second communication state operates to release the connection of the 5G network communication for the terminal and maintain 4G network communication for the terminal based on the first communication state being a E-UTRA NR dual connectivity state, and
• wherein the second communication state operates to release the connection of the 5G network communication for the terminal and establish 4G network communication for the terminal based on the first communication state being a 5G stand-alone connectivity state.
