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). The present disclosure provides an operating method and apparatus for supporting a handover to support a high reliability and low latency service in a wireless communication system. The method of operating the terminal includes receiving data from a service via a first base station (BS), transmitting, to the first BS, a bearer establishment command message between the first BS and a second BS determined by movement information of the terminal, and receiving, from the second BS, data transmitted from the second BS via the established bearer between the first BS and the second BS.
