performing provisioning of information included in the second message to the UE via an access and mobility management function (AMF),

wherein the information for identifying the service is represented by at least one of a combination of a data network name (DNN) and single network slice selection assistance information (S-NSSAI), an application function (AF)-service-identifier and an application identifier, and

wherein the service parameter information is included in request information transmitted from a server to a network exposure function (NEF), and the service parameter information includes:

in case the UE is in coverage, information on a public land mobile network (PLMN) in which the UE is authorized to perform the service and radio access technology (RAT) over which the UE is authorized to perform the service in the PLMN, and

in case the UE is out of coverage, information for indicating whether the UE is authorized to perform the service.

10. The method of claim 9 , wherein the second message further includes identification information of the UE.

11. An entity that implements a network exposure function (NEF) in a communication system, the entity comprising:

a transceiver configured to transmit/receive a signal to/from an internal or external network entity; and

a controller configured to:

receive, from a server, a request message including request information related to a service, the request information including information for identifying the service and service parameter information for delivering to a user equipment (UE) to support the service,
