storing the first service API information in an API registry;
receiving, from an API invoker, a service API discover request message including a UE IP address for discovering at least one service API;
retrieving the first service API information from the API registry based on the UE IP address, wherein the first service API information corresponds to the service API discover request message; and
transmitting, to the API invoker, a service API discover response message including the first service API information.
