3.1 Definitions

For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in 3GPP TR 21.905 [1].

VAL user: An authorized user, who can use a VAL UE to participate in one or more VAL services.

VAL user ID: A generic name for the user ID of a VAL user within a specific VAL service.

VAL UE: A UE that can be used to participate in one or more VAL services.

VAL client: An entity that provides the client side functionalities corresponding to the vertical applications.

SEAL client: An entity that provides the client side functionalities corresponding to the specific SEAL service.

VAL service: A generic name for any service offered by the VAL service provider to their VAL users.

SEAL service: A generic name for a common service (e.g. group management, configuration management, location management) that can be utilized by multiple vertical applications.

SEAL provider: Provider of SEAL service(s).

VAL server: A generic name for the server application function of a specific VAL service.

SEAL server: An entity that provides the server side functionalities corresponding to the specific SEAL service.

VAL system: The collection of applications, services, and enabling capabilities required to support a VAL service.

Primary VAL system: VAL system where the VAL user profiles of a VAL user are defined.

Partner VAL system: A VAL system that has a business relationship with the primary VAL system such that service can be offered to primary VAL system users.

VAL group: A defined set of VAL UEs or VAL users configured for specific purpose in a VAL service.

NOTE: The set could be of either VAL UEs or VAL users depending on the specific VAL service.

VAL group home system: The VAL system where the VAL group is defined.

VAL group member: A VAL service user, whose VAL user ID is listed in a particular VAL group.

VAL stream: A time sensitive communication stream is used to transport a time sensitive data flow, and is defined by a stream specification (which identifies a source and destination of the data flow) and a traffic specification (which defines the characteristics of the data flow). VAL stream is identified by a VAL stream ID.

Vertical: See vertical domain.

Vertical application: An application catering to a specific vertical.

MBS session announcement: Mechanism to provide the necessary information to the NRM client to enable the reception of the VAL service data via the MBS session.
