1. A method performed by a base station in a communication system, the method comprising:
if the base station receives a first location report request for a first terminal from an access and mobility management function (AMF) entity,
transmitting, to the AMF entity, a first location report including last known location information of the first terminal identified by the base station and a time stamp associated with the last known location information of the first terminal, while the first terminal is in a radio resource control (RRC) inactive state; and
if the base station receives a second location report request for a second terminal from the AMF entity, performing a radio access network (RAN) paging for the second terminal, and transmitting, to the AMF entity, a second location report including information on a location of the second terminal which is based on the RAN paging, while the second terminal is in the RRC inactive state,
wherein the last known location information of the first terminal includes an identity of a cell for the first terminal, and
wherein the information on the location of the second terminal includes an identity of a cell for the second terminal.
