Description

Method and apparatus for measuring QOE in inactive mode and standby mode in wireless communication system Technical Field The present disclosure relates to wireless communication systems (or mobile communication systems). In particular, the present disclosure relates to a method for measuring quality of experience (QoE) in a Radio Resource Control (RRC) inactive mode or RRC standby (or idle) mode in a wireless communication system (or mobile communication system). Background The 5G mobile communication technology defines a wide frequency band, enables high transmission rates and new services, and can be implemented not only in the "6 GHz below" frequency band such as 3.5 GHz, but also in the "6 GHz above" frequency band called millimeter waves (including 28 GHz and 39 GHz). In addition, it has been considered to implement a 6G mobile communication technology (referred to as a super 5G system) in a terahertz frequency band (e.g., 95 GHz to 3 THz frequency bands) in order to achieve a transmission rate five times faster than that of the 5G mobile communication technology and an ultra-low delay that is one tenth of that of the 5G mobile communication technology. At the beginning of the development of 5G mobile communication technology, in order to support services and meet performance requirements related to enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC) and massive machine type communication (mMTC), standardization has been in progress involving beamforming and massive MIMO in order to mitigate radio wave path loss in millimeter waves and increase radio wave transmission distances, support for parameter sets (e.g., operating multiple subcarrier intervals) for dynamic operation that effectively utilize millimeter wave resources and slot formats, initial access techniques for supporting multi-beam transmission and broadband, definition and operation of BWP (bandwidth part), new channel coding methods such as LDPC (low density parity check) codes for mass data transmission and polarization codes for highly reliable transmission of control information, L2 preprocessing, and network slicing for providing a dedicated network for specific services. Currently, in view of the services supported by the 5G mobile communication technology, discussions on improvement and performance improvement of the initial 5G mobile communication technology are underway, and already existing physical layer standardization such as technologies including V2X (Internet of vehicles) for assisting an autonomous vehicle in making driving decisions and improving user convenience based on information sent by the vehicle about the position and state of the vehicle, NR-U (new radio unlicensed) aimed at system operation meeting various regulatory-related requirements in unlicensed bands, NR UE energy saving technology, non-terrestrial network (NTN) which is UE-satellite direct communication for providing coverage in an area where terrestrial network communication is unavailable, and positioning. Furthermore, in terms of air interface architecture/protocols, technologies that are continuously standardized include, for example, industrial internet of things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (integrated access and backhaul) for providing nodes for the extension of network service areas by supporting wireless backhaul links and access links in an integrated manner, mobility enhancements including conditional handoffs and DAPS (dual active protocol stack) handoffs, and two-step random access (2-step RACH for NR) for simplifying the random access procedure. Are also being standardized in terms of system architecture/services, including 5G baseline architecture (e.g., service-based architecture or service-based interface) for combining Network Function Virtualization (NFV) and Software Defined Network (SDN) technologies, and service Mobile Edge Computing (MEC) for receiving services based on UE location. With commercialization of the 5G mobile communication system, a connection device that has been exponentially increased will be connected to the communication network, and thus it is expected that enhancement of functions and performance of the 5G mobile communication system and integrated operation of the connection device will be required. To this end, new studies are being planned to include increasing 5G performance and reducing complexity, AI service support, metauniverse service support, and unmanned aerial vehicle communication by using Artificial Intelligence (AI) and Machine Learning (ML) for effectively supporting augmented reality (XR) of AR (augmented reality), VR (virtual reality), MR (mixed reality), etc. Furthermore, such development of 5G mobile communication systems will not only lay a foundation for development of technology for providing new waveforms for coverage in terahertz frequency bands of 6G mobile communication technologies, mu
