Description

Mobile Base Station and Mobile Base Station Service System The present invention relates to a mobile base station and a mobile base station service system. This invention was promoted as part of a national research and development project and is being carried out from November 2023 to October 2026 with 100% contribution from the Ministry of Trade, Industry and Energy and the Defense Acquisition Program Administration in relation to the civil-military technology cooperation project led by the Agency for Defense Development, under the research project title "Development of Next-Generation Wireless Communication System for 5G Security Operations" (Project No. 23-CM-TC-13). Next-generation mobile communication systems are evolving in the direction of using high-frequency or ultra-high-frequency bands, as they must use wide bandwidth to provide ultra-high-speed wireless data services. Advanced manufacturing nations such as Germany and Japan are advocating the Fourth Industrial Revolution and utilizing mobile communication technologies such as Private 5G in smart factories for high-productivity and high-quality manufacturing by leveraging AI, robots, and ultra-high-definition video. In particular, the need for next-generation mobile communication systems is emerging in specific regions or disaster situations, such as disaster networks and small-scale smart factories. Disaster networks are designed for environments where existing communication infrastructure has been destroyed or where it is difficult to establish such infrastructure, such as mountainous regions, earthquake zones, and areas with collapsed buildings. If a person requesting rescue in a disaster area possesses a mobile phone, rescue can be facilitated by moving a temporary wireless infrastructure to communicate via phone. Alternatively, even if the person does not make a direct call or request rescue, the mobile phone's signal can be detected and tracked through the wireless infrastructure. Furthermore, for small-scale smart factories, it is difficult to invest in expensive wireless communication infrastructure, such as access and core systems, as well as solutions related to Digital Transformation (DX), which is part of the Fourth Industrial Revolution. There is a high need for lightweight wireless communication infrastructure that can introduce and verify the effectiveness of DX solutions. Furthermore, in military and security situations, there is a similar high need for high-quality wireless communication services in specific regions where existing wireless infrastructure is insufficient or absent. In the case of the military, high-capacity wireless data services are essential not only for communication among unit members within a region but also for the advancement of operations in environments where wireless infrastructure cannot exist, such as during infiltration into enemy territory. In security operations, sharing information via conventional radios faces significant limitations in accurately assessing the status of the protected person or conveying action guidelines during emergencies. Therefore, the development of next-generation mobile communication-based wireless data service infrastructure is necessary to advance security measures, such as transmitting status video and locating bodyguards.
