Abstract
An operating method of a base station supporting time synchronization of a terminal in a wireless communication system is provided. The operating method includes obtaining, with respect to the terminal connected to the base station, a synchronization indicator indicating whether the terminal requests time synchronization, obtaining, from an application function (AF) or a network exposure function (NEF), a synchronization accuracy required for the time synchronization of the terminal, and activating or deactivating a time synchronization function, based on the synchronization indicator and the synchronization accuracy.
Claims12
A method performed by a base station (BS) supporting time synchronization service for a terminal in a wireless communication system, the method comprising:
- receiving at least one synchronization parameter for controlling time synchronization service of the BS from Access and Mobility Function (AMF) based on subscription information of the terminal identified by the AMF during a registration procedure, wherein the at least one synchronization parameter comprises a synchronization indicator indicating whether to activate or deactivate the time synchronization service and a synchronization accuracy required to the time synchronization service, and wherein the time synchronization service comprises a service to provide time information to the terminal by using an interface between the BS and the terminal;
- activating or deactivating the time synchronization service of the BS, based on the synchronization indicator;
- and
- providing time information to the terminal based on the synchronization accuracy.
A base station (BS) supporting time synchronization service for a terminal in a wireless communication system, the BS comprising:
- a transceiver;
- and
- at least one processor coupled to the transceiver and configured to:
- receive at least one synchronization parameter for controlling time synchronization service of the BS from Access and Mobility Function (AMF) based on subscription information of the terminal identified by the AMF during a registration procedure, wherein the at least one synchronization parameter comprises a synchronization indicator indicating whether to activate or deactivate the time synchronization service and a synchronization accuracy required to the time synchronization service, and wherein the time synchronization service comprises a service to provide time information to the terminal by using an interface between the BS and the terminal,
- activate or deactivate the time synchronization service of the BS, based on the synchronization indicator, and
- provide time information to the terminal based on the synchronization accuracy.
