Provided are an electronic device, a method thereof, and a server. The electronic device includes a display, a communication interface, at least one processor, and a memory electrically connected to the processor, wherein, upon execution, the memory is configured to store instructions that enable the at least one processor to detect that a call event associated with another electronic device occurs; obtain call-related information associated with the another electronic device; detect at least one piece of information corresponding to a call state with the another electronic device from the obtained call-related information; and control the display to display a screen including the at least one piece of detected information and information indicating the call state with the another electronic device. Other embodiments may be possible.

Electronic device for displaying call-related information and operation method thereof

A power control method and an apparatus for controlling power mode of a User Equipment (UE) operating on multiple frequencies are provided. The terminal includes a primary module for primary cell communication and a secondary module for secondary cell communication. The method includes receiving a secondary cell adding message for adding a secondary cell from a base station, checking data-related information on data communicated through at least one of the primary module and a secondary module, and determining a power mode of the secondary module based on the checking.

Power control method and apparatus of user equipment using multi-frequency

A method and device for transmitting a location registration result of a portable terminal that is adapted for connected with two or more networks includes transmitting to a first network a location registration request message for location registration, receiving a location registration rejection message including location registration rejection information from the first network when the location registration fails, and transmitting to a second network a location registration request message including the location registration rejection information. The second network can notify the portable terminal when a re-attempted connection with the first network can be performed to save on processing power for repeated re-connection attempts with the first network that will not be successful.
