Description

Method and apparatus for estimating base station information The present invention relates to a method for estimating information of a base station and an apparatus for performing the method. Recently, interest in urban air mobility (UAM) has been rising, particularly among developed nations. Korea has also conducted comprehensive demonstrations of a Korean-style urban air mobility system and is now on the verge of commercialization. According to the technology roadmap for Korean urban air mobility, the operating altitude of UAM aircraft is expected to be around 300 to 600 meters, the maximum operating speed is expected to be around 320 km/h, and it is expected to be operated along a predetermined flight path. Base stations are scheduled to be installed along the flight paths of UAM aircraft to support data transmission and reception services for UAM aircraft, and each base station is responsible for communication within a certain range to provide aerial network services along the flight paths of UAM aircraft. Meanwhile, for smooth aerial network services, coverage design for each base station is required, and to achieve this, it is necessary to construct a radio wave map of the aerial network. However, while constructing a radio wave map of the airspace requires various detailed information, including the antenna angles (upward and/or directional angles) of base stations, difficulties arise in doing so because, in the case of base stations operated by different entities—for example, those operated by different operators—most detailed information is often undisclosed, with the exception of basic information such as location and frequency data. Figure 1 is a conceptual diagram showing an example in which radio quality data is acquired by a drone, etc., at each of the separated local areas within the airspace above a base station for an aerial network service. FIG. 2 is an exemplary configuration diagram of a base station information estimation device capable of performing a base station information estimation method according to one embodiment. FIGS. 3 to 5 are exemplary diagrams of a radio quality coordinate system that can be implemented based on radio quality data measured at any locality above a base station for an aerial network service according to one embodiment. FIG. 6 is an exemplary flowchart for explaining a base station information estimation method performed by a base station information estimation device according to one embodiment, showing the process up to the construction of a radio wave map of an air network by applying the estimated base station information.
