6.1 General

This clause describes the identities associated with the entities in the FF application layer and used in this specification.

6.2 Identities

6.2.1 FF user identity (FF user ID)

The FF user ID can be an instance of the VAL user ID as specified in 3GPP TS 23.434 [5]. The FF user ID is a globally unique identifier within the FF service that represents the FF user. The FF user ID shall be a URI. The FF user ID is used for authentication and authorization purposes for providing the FF service towards the FF user via the FF UE. The FF user ID also indicates the FF service provider with whom the FF user has a FF service agreement. The FF user may have FF service agreement with several FF service providers and thus will have obtained unique FF user ID per FF service provider.

Based on the service agreement, each FF user ID is mapped to a FF UE ID.

6.2.2 FF UE identity (FF UE ID)

The FF UE ID can be an instance of the VAL UE ID as specified in 3GPP TS 23.434 [5]. The FF UE ID is a unique identifier within the FF service that represents the FF UE. Generally, the FF UE ID is a 3GPP UE ID which is identity of the 3GPP UE combined with a FF hardware device (e.g. motion control unit, mobile robot, AGV) and deployed in factory environment. The 3GPP UE ID can be a GPSI in the form of an External Identifier which maps to UE related specific services (e.g. TSN DS-TT, 5G LAN-type service, SNPN, PNI-NPN) specified in 3GPP TS 23.501 [4] and 3GPP TS 23.502 [8].

6.2.3 FF group identity (FF group ID)

The FF group ID is a globally unique identifier within the FF service that represents a set of FF users and the corresponding FF UE. The set of FF users may belong to the same or different FF service provider. It indicates the FF application server where the group is defined. The FF group ID can be an instance of the VAL group ID as specified in 3GPP TS 23.434 [5].

6.2.4 FF Application Specific Server Identifier (FASS ID)

The FF application specific server identifier is used to uniquely identify the FF application specific server. The FASS ID is in the form of URI.

6.2.5 FAE Server Identifier (FAE Server ID)

The FAE server identifier is used to uniquely identify the FAE server. The FAE Server ID is in the form of URI.
