retrieve, from a configuration management server or an MSGin5G configuration function via the transceiver, the association information of the terminal based on the received terminal ID, and
verify whether the terminal service ID included in the registration request message is associated with the terminal ID included in the retrieved association information.
9 . The MSGin5G server of claim 8 , wherein the at least one processor is further configured to:
provide, to the terminal, an access for a service based on a result of the verification.
10 . The MSGin5G server of claim 8 , wherein the association information of the terminal is retrieved based on the terminal ID received from the AAnF entity.
11 . The MSGin5G server of claim 8 , wherein the at least one processor is further configured to:
verify whether the terminal service ID included in the registration request message is associated with the terminal ID included in the retrieved association information.
12 . The MSGin5G server of claim 8 , wherein the terminal ID comprises a subscription permanent identifier (SUPI) or a generic public subscription identifier (GPSI).
13 . The MSGin5G server of claim 8 , wherein the at least one processor is further configured to perform an authorization operation for the terminal by retrieving an association between the terminal service ID and the terminal ID, and
wherein the terminal is an MSGin5G terminal.
14 . The MSGin5G server of claim 8 , wherein an association between the terminal service ID and the terminal ID is maintained by the configuration management server or the MSGin5G configuration function.
15 . A method performed by a terminal, the method comprises:
transmitting, to a message service within a 5 th generation system (MSGin5G) server, a registration request message including a terminal service identifier (ID); and
receiving, from the MSGin5G server, a response message including information indicating whether an access to a service is provided,
wherein a terminal ID is transmitted from an authentication and key management for applications (AKMA) anchor function (AAnF) entity to the MSGin5G server, and the terminal ID is used for retrieving association information of the terminal,
wherein the association information of the terminal is retrieved from a configuration management server or an MSGin 5 G configuration function based on the terminal ID, and
wherein whether the terminal service ID included in the registration request message is associated with the terminal ID included in the retrieved association information is verified.
16 . The method of claim 15 , wherein the access to the service is provided based on a result of the verification,
wherein the association information of the terminal is retrieved based on the terminal ID received from the AAnF entity,
wherein whether the terminal service ID included in the registration request message is associated with the terminal ID included in the retrieved association information is verified, and
wherein the terminal ID comprises a subscription permanent identifier (SUPI) or a generic public subscription identifier (GPSI).
17 . The method of claim 15 , wherein an association between the terminal service ID and the terminal ID is maintained by the configuration management server or the MSGin5G configuration function.
18 . A terminal, the terminal comprises:
a transceiver; and
at least one processor operably coupled to the transceiver, the at least one processor configured to:
