1. A method for providing an ultra-reliable and low-latency communication (URLLC) service in an ultra-reliable and low-latency communication function (URLLCF) of a mobile communication system, the method comprising:
receiving an end-to-end latency request message from an application function (AF) device, the end-to-end latency request message including a latency requirement and at least one of generic public subscription identifier (GPSI) information of a specific user equipment (UE), data network name (DNN), or single-network slice selection assistance (S-NSSAI);
performing a subscription procedure of URLLC service condition with a unified data management (UDM)/user data repository (UDR) device;
obtaining location information of the UE;
identifying whether the location information conforms to a range required by the URLLC service;
configuring a policy and association satisfying a latency for the URLLC service to the UE; and
providing a URLLC service notification to the AF based on the configuration.
