Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the disclosure, an operating method of a user plane function (UPF) in a wireless communication system and an apparatus therefor are provided. The operating method includes receiving a first parameter for clock synchronization from a base station, and performing the clock synchronization with a neighboring network system using the received first parameter and a second parameter. The first parameter may include information relating to a link delay time between the neighboring network system and a network system comprising the UPF, and a residence time of a terminal, a base station and the UPF of the network system comprising the UPF, and the second parameter may include information relating to a backhaul delay time between the base station and the UPF.
