The present disclosure relates to a communication technique for converging a 5G communication system for supporting a higher data rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure provides a method and a device for enhancing data security. The method includes when a request message including information related to a first privacy level is received from a user device, authenticating the user device. The method also includes verifying the information related to the first privacy level. The method further includes transmitting, to the terminal, an image processed on the basis of the first privacy level among images processed on the basis of a plurality of privacy levels.

Apparatus and method for enhancing personal information data security

Provided is a User Equipment (UE) in a wireless communication system supporting a Circuit Switched FallBack (CSFB) service. The UE includes a transceiver for transmitting and receiving a signal to/from a first or second communication system that uses a different frequency; a receiver for receiving a signal from the second communication system; and a controller for controlling an operation of receiving signaling information for the CSFB service from the first communication system through the transceiver, and simultaneously measuring channel status of the second communication system using the signal received from the receiver.

Method and apparatus for performing communication by UE in wireless communication system supporting circuit switched fallback service

The time required to set up a voice call in an exemplary embodiment, in which Circuit Switched Fallback (CSFB) is used, is reduced to provide a voice call service to a User Equipment (UE) in a Long Term Evolution (LTE) system. If a voice call occurs in a UE while the UE accesses the LTE system, the UE using CSFB switches to a 2G/3G legacy system, recycles system information for a 2G/3G cell that the UE has accessed before, and immediately proceeds with voice call setup without receiving system information unnecessary for a CSFB process.

Method and apparatus for setting up call in mobile communication system

To provide information of a device in communication between devices, an operating method of a device includes including device information of the device in a message defined by a communication protocol used to connect to the other device; and transmitting the message comprising the device information using the communication protocol. The device information comprises at least one of a device type, support of a mirror link, mobile communication network connection support, automatic execution of an application corresponding to the device, vendor identification information, and product identification information.

Apparatus and method for exchanging information on device in communication between devices

A method for inputting characters in a mobile terminal is provided. The method involves the steps of detecting any key pressing event on a key input unit, storing the detected key pressing event and performing an operation corresponding to the key pressing event, determining whether a predetermined multi-click key is pressed after the previous key pressing event, and when the multi-click key is pressed, performing the operation corresponding to said key pressing event occurring repeatedly a predetermined number of times.
