Description

BACKGROUND The disclosure relates to an apparatus for vehicle communication in a wireless communication system and an operating method of the wireless communication system. Recently, along with the development of vehicle technologies, the role of in-vehicle infotainment (IVI) has increased. IVI is an electronic device mounted in a vehicle to provide various pieces of information and services to a user in the vehicle. As terminal devices, such as smartphones, and various vehicle Internet of Things (IoT) devices, are commercialized, a user in a moving vehicle may receive various pieces of information and services through a terminal device and/or an IoT device. For example, the user may use application information provided by a terminal device through IVI or use an application configured to provide a vehicle-related service in the terminal device through the IVI. Recently, IVI techniques of providing complex services in which vehicle-related services and mobile communication-related services are combined with each other, based on a link between a vehicle and a terminal device (or an IoT device), have been developed. Accordingly, to smoothly provide such complex services, an efficient private network become necessary because the efficient private network may minimize the control overhead between an electronic device for vehicle communication in a vehicle and a terminal (or an IoT device). US 2023/300580 A1 (SINGH AJOY K ET AL, 21 September 2023) discloses an invention in which a connected car and an onboard user equipment (UE) may establish independent cellular connections and may also establish a connection between each other.
