Various embodiments of the disclosure relate to an apparatus and a method for rapidly acquiring a cell through direct communication by an electronic device. The electronic device may include: a memory, a first communication circuit, a second communication circuit, and at least one processor, and the processor may be configured to control the electronic device to: acquire a network list corresponding to each of at least one service area, based on the network information of the at least one external electronic device acquired through direct communication using the second communication circuit, acquire a frequency corresponding to the service area in which the electronic device is located, based on the network list based on determining that the service area of the electronic device is changed, and access a cell detected by a network search based on the frequency corresponding to the service area in which the electronic device is located through the first communication circuit.

Electronic device for acquiring cell and method of operating same

Disclosed are a cipher control method which supports to maintain a cipher mode between a network system and a terminal. The method of controlling an encryption includes: attempting a connection for operating a communication channel between a terminal and a network system; providing cipher information about a cipher algorithm operation of the terminal to the network system; determining whether the terminal is a problematic terminal operating an abnormal cipher algorithm by the networking system; and when the terminal is determined to be operating abnormal, instructing the terminal to perform a communication channel operation based on a normally operable cipher algorithm by the network system.
