Method for analyzing communication quality and apparatus supporting it {METHOD FOR ANALYZING COMMUNICATION QUALITY AND APPARATUS SUPPORTING THEREOF}

Various embodiments relate to a method for analyzing communication quality and an apparatus supporting the same.

A wireless communication system is widely deployed to provide various types of communication services such as voice and data. In general, a wireless communication system is a multiple access system capable of supporting communication with multiple users by sharing available system resources (bandwidth, transmission power, etc.). Examples of the multiple access system include a code division multiple access (CDMA) system, a frequency division multiple access (FDMA) system, a time division multiple access (TDMA) system, an orthogonal frequency division multiple access (OFDMA) system, and a single carrier frequency (SC-FDMA) system. There is a division multiple access (MC-FDMA) system and a multi carrier frequency division multiple access (MC-FDMA) system.

Device-to-Device (D2D) communication refers to a communication method in which a direct link is established between User Equipments (UEs) to directly exchange voice and data between the UEs without going through a base station. D2D communication may include UE-to-UE communication, peer-to-peer communication, and the like. In addition, the D2D communication scheme may be applied to Machine-to-Machine (M2M) communication, Machine Type Communication (MTC), and the like.

In a wireless communication system, a service operator and/or a network manager needs to quickly grasp service quality in order to provide a cause analysis and action guide for a service failure accident. In the case where such service quality is identified by analyzing log data for each terminal by technical personnel, there is a problem in that manpower and time resources are consumed.
