Description

Apparatus and Method for Mobility Management of Unmanned Aerial Vehicle Using Flight Mission and Route in Mobile Communication System The present disclosure relates to a wireless communication system, and more specifically, to an apparatus and method for controlling the movement path of an Unmanned Aerial Vehicle (UAV) through the exchange of information between an Unmanned Aerial Vehicle (UAV), an Unmanned Aerial Vehicle Controller (UAV) that controls the UAS, and an Unmanned Aerial Vehicle Traffic Management (UTM) system that controls the UAS in a mobile communication system. Efforts are being made to develop improved 5G or pre-5G communication systems to meet the increasing demand for wireless data traffic since the commercialization of 4G communication systems. For this reason, 5G or pre-5G communication systems are referred to as Beyond 4G Network communication systems or Post-LTE systems. To achieve high data transmission rates, the implementation of 5G communication systems in the mmWave band (e.g., the 60 GHz band) is being considered. To mitigate path loss and increase transmission distance in the mmWave band, technologies such as beamforming, massive MIMO, full Dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antennas are being discussed for 5G communication systems. In addition, to improve the network of the system, technologies such as advanced small cell, advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, Device to Device communication (D2D), wireless backhaul, moving network, cooperative communication, Coordinated Multi-Points (CoMP), and interference cancellation are being developed in 5G communication systems. Furthermore, in 5G systems, advanced coding modulation (ACM) methods such as FQAM (Hybrid FSK and QAM Modulation) and SWSC (Sliding Window Superposition Coding), as well as advanced access technologies such as FBMC (Filter Bank Multi Carrier), NOMA (non-orthogonal multiple access), and SCMA (sparse code multiple access) are being developed. Meanwhile, the Internet is evolving from a human-centered network where humans generate and consume information into an IoT (Internet of Things) network where distributed components, such as objects, exchange and process information. IoE (Internet of Everything) technology, which combines IoT with Big Data processing technologies through connections with cloud servers, is also emerging. To implement IoT, technological elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology are required; consequently, technologies such as sensor networks, Machine-to-Machine (M2M) communication, and Machine-Type Communication (MTC) are currently being researched to facilitate the connection of objects. In an IoT environment, intelligent IT services that create new value for human life by collecting and analyzing data generated from connected objects can be provided. Through the convergence and integration of existing IT technologies with various industries, IoT can be applied to fields such as smart homes, smart buildings, smart cities, smart or connected cars, smart grids, healthcare, smart home appliances, and advanced medical services. Accordingly, various attempts are being made to apply 5G communication systems to IoT networks. For example, technologies such as sensor networks, Machine to Machine (M2M), and Machine Type Communication (MTC) are being implemented using 5G communication techniques such as beamforming, MIMO, and array antennas. The application of cloud RAN as a big data processing technology, as previously described, can also be considered an example of the convergence of 5G and IoT technologies. Meanwhile, unmanned aerial vehicles (UAVs) are a type of terminal expected to receive services via mobile communication networks in the near future. Currently, operating drones does not support the use of cellular networks, such as mobile communication. Most current operational methods generally rely on short-range wireless communication networks (RF), Bluetooth, and Wi-Fi, utilizing protocols provided by manufacturers to control the drone and its controller. Therefore, to control UAVs using mobile communication networks, research is required on issues not encountered in existing short-range networks, as well as problems and improvements related to drone mobility.
