1 Scope
The present document defines the stage 3 specifications of the Supplementary Service Dynamic Group Number
Assignment (SS-DGNA) for the Terrestrial Trunked Radio (TETRA).
The SS-DGNA enables a user to dynamically define group identities and group related parameters to the TETRA
system and to the subscribers in the system. These definitions are used to enable group call invocations to dynamically
defined groups. The SS-DGNA specification defines the creation, modification, deletion and interrogation of group
definitions in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS).
The present document does not include the specification for access priority used for random access in uplink and call
priority used by SwMI for resource allocation in a group call. Access priority and call priority can be specified and
applied for groups using Supplementary Services Access Priority (SS-AP), Priority Call (SS-PC) and Pre-emptive
Priority Call (SS-PPC). Thus, the definition procedure of these priorities is outside the scope of the present document.
Man-Machine Interface (MMI) and charging principles are also outside the scope of the present document.
Supplementary service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service.
Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in
terms of functional entities and information flows. Stage 3 gives the precise description of the supplementary service
from the implementation point of view. It defines the protocols for the service and the encoding rules for the
information flows. It defines the processes for the functional entities and their behaviour. The described protocols and
their behaviour apply for the SwMI and for the MS and can be applied over the Inter-System Interface (ISI) between
TETRA systems.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
affected user: identified MS user to whom the group is assigned (added to) or deassigned (removed from)
NOTE: Affected user can also interrogate group information based on group numbers. Also SwMI can interrogate
group information from affected user.

group numbers/affected user identities
call related SS-DGNA: creation of a group whose members (affected users) are based on the participants of a
referenced call and possibly also based on given affected user identities
call unrelated SS-DGNA: creation of a group whose members (affected users) are solely based on given affected user
identities

4 Functional model
4.1 Functional entities
The functional model for SS-DGNA consists of Functional Entities FE1 to FE3 as defined in ETS 300 392-11-22 [2],
clause 4.1. Refer to EN 300 392-9 [6] for Inter-System Interface model (ISI).
These functional entities can, for one action, be located in different TETRA SwMIs as defined in
ETS 300 392-11-22 [2], clause 4.
4.2 Mapping of functional entities to Circuit Mode Control
Entities (CMCE)
FEs, CCs and PCs correspond to sub-entities in the Circuit Mode Control Entity (CMCE) described in
EN 300 392-2 [3] according to the following definitions:
- FE1: Supplementary Service (SS) sub-entity in CMCE in affected user's MS.
- FE2: SS sub-entity in CMCE in SwMI.
- FE3: SS sub-entity in CMCE in authorized user's MS.
- CC: Call Control (CC) sub-entity in CMCE in SwMI or in MS.
- PC: Protocol Control (PC) sub-entity in CMCE in MS.
4.3 Protocol structure and protocol stack
The MS protocol stack is defined in EN 300 392-2 [3].
SS-DGNA PDUs shall be routed as specified in EN 300 392-9 [6], at the air interface in U/D-FACILITY PDUs and
using ANF-ISISS for conveying SS-DGNA PDUs over the ISI.

5 SS-DGNA service description
5.1 General
Clauses 5.2 to 5.4 describe SS-DGNA specific services offered by the CMCE at the supplementary services service
access point (TNSS-SAP) to application, or vice versa, of the TETRA Voice plus Data (V+D) layer 3 service boundary.
NOTE: As the present document only deals with the SS-DGNA all the service primitives has been shown without
a TNSS-DGNA-prefix e.g. the TNSS-DGNA-DEFINE request is shortened into a DEFINE request.
Refer EN 300 392-9 [6] for general information on supplementary services.
In this protocol model the application is considered to manage group information in the MS. The management
mechanisms and a detailed information exchange between MS protocol layers are outside the scope of the present
document.
5.2 SS-DGNA services offered over the TNSS-SAP
The services offered to users of SS-DGNA are defined as service primitives containing service parameters. The service
primitives are defined in clause 5.3 and the parameter in the service primitives are defined in clause 5.4.
In addition to the defined service primitives a SwMI/MS may response by a supplementary service not supported or an
action not supported primitives as appropriate, refer EN 300 392-9 [6] and clauses 6.2.18 and 6.2.19.
NOTE: As the man-machine interface or user application are outside the scope of the present document service
primitives are used to define information exchange to and from the standardized part of the MS. Those
primitives may be only indirectly accessible.
5.3 SS-DGNA primitives
The SS-DGNA service primitives at the Affected user MS (FE1) TNSS-SAP are:
a) ASSIGN indication;
b) ASSING response;
c) DEASSIGN indication;
d) DEASSING response;
e) INTERROGATE GROUP request;
f) INTERROGATE GROUP indication;
g) INTERROGATE MS GROUPS indication;
h) INTERROGATE MS GROUPS response.
ETSI
12 Draft ETSI EN 300 392-12-22 V1.3.3 (2014-09)
The SS-DGNA service primitives at the authorized user MS (FE3) TNSS-SAP are:
a) DEFINE request;
b) DEFINE indication;
c) DELETE request;
d) DELETE indication;
e) INTERROGATE GROUP request;
f) INTERROGATE GROUP indication;
g) INTERROGATE GROUP MEMBERS request;
h) INTERROGATE GROUP MEMBERS indication;
i) MODIFY request;
j) MODIFY indication;
k) INTERROGATE MS GROUPS request;
l) INTERROGATE MS GROUPS confirm.
The service primitives such as MODIFY request and MODIFY indication are related to each other by the group
identity, if available. There can be more than one indication primitive related to a single request primitive.
5.3.1 ASSIGN indication
ASSIGN indication primitive shall be offered from FE1 to application over TNSS-SAP in order to assign group
identities and/or parameters related to the group to the database in the affected user's MS. The primitive shall contain

ETSI ETSI EN 300 392-12-22 V1.4.1 (2015-02)8 1 Scope The present document defines the stage 3 specifications of the Supplementary Service Dynamic Group Number Assignment (SS-DGNA) for the Terrestrial Trunked Radio (TETRA). The SS-DGNA enables a user to dynamically define group identities and group related parameters to the TETRA system and to the subscribers in the system. These definitions are used to enable group call invocations to dynamically defined groups. The SS-DGNA specification defines the creation, modification, deletion and interrogation of group definitions in the Switching and Management Infrastructure (SwMI), in the Mobile Station (MS). The present document does not include the specification for access priority used for random access in uplink and call priority used by SwMI for resource allocation in a group call. Access priority and call priority can be specified and applied for groups using Supplementary Services Access Priority (SS-AP), Priority Call (SS-PC) and Pre-emptive Priority Call (SS-PPC). Thus, the definition procedure of these priorities is outside the scope of the present document. Man-Machine Interface (MMI) and charging principles are also outside the scope of the present document. Supplementary service stage 3 specification is preceded by the stage 1 and the stage 2 specifications of the service. Stage 1 describes the functional capabilities from the user's point of view. Stage 2 defines the functional behaviour in terms of functional entities and information flows. Stage 3 gives the precise description of the supplementary service from the implementation point of view. It defines the protocols for the service and the encoding rules for the information flows. It defines the processes for the functional entities and their behaviour. The described protocols and their behaviour apply for the SwMI and for the MS and can be applied over the Inter-System Interface (ISI) between TETRA systems. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Refer to EN 300 392-9 [6] for Inter-System Interface model (ISI). These functional entities can, for one action, be located in different TETRA SwMIs as defined in ETS 300 392-11-22 [2], clause 4. 4.2 Mapping of functional entities to Circuit Mode Control Entities (CMCE) FEs, CCs and PCs correspond to sub-entities in the Circuit Mode Control Entity (CMCE) described in EN 300 392-2 [3] according to the following definitions: - FE1: Supplementary Service (SS) sub-entity in CMCE in affected user's MS. - FE2: SS sub-entity in CMCE in SwMI. - FE3: SS sub-entity in CMCE in authorized user's MS. - CC: Call Control (CC) sub-entity in CMCE in SwMI or in MS. - PC: Protocol Control (PC) sub-entity in CMCE in MS. 4.3 Protocol structure and protocol stack The MS protocol stack is defined in EN 300 392-2 [3]. SS-DGNA PDUs shall be routed as specified in EN 300 392-9 [6], at the air interface in U/D-FACILITY PDUs and using ANF-ISISS for conveying SS-DGNA PDUs over the ISI.

ETSI ETSI EN 300 392-12-22 V1.4.1 (2015-02)11 5 SS-DGNA service description 5.1 General Clauses 5.2 to 5.4 describe SS-DGNA specific services offered by the CMCE at the supplementary services service access point (TNSS-SAP) to application, or vice versa, of the TETRA Voice plus Data (V+D) layer 3 service boundary. NOTE: As the present document only deals with the SS-DGNA all the service primitives has been shown without a TNSS-DGNA-prefix e.g. the TNSS-DGNA-DEFINE request is shortened into a DEFINE request. Refer EN 300 392-9 [6] for general information on supplementary services. In this protocol model the application is considered to manage group information in the MS. The management mechanisms and a detailed information exchange between MS protocol layers are outside the scope of the present document. 5.2 SS-DGNA services offered over the TNSS-SAP The services offered to users of SS-DGNA are defined as service primitives containing service parameters. The service primitives are defined in clause 5.3 and the parameter in the service primitives are defined in clause 5.4. In addition to the defined service primitives a SwMI/MS may response by a supplementary service not supported or an action not supported primitives as appropriate, refer EN 300 392-9 [6] and clauses 6.2.18 and 6.2.19. NOTE: As the man-machine interface or user application are outside the scope of the present document service primitives are used to define information exchange to and from the standardized part of the MS. Those primitives may be only indirectly accessible. 5.3 SS-DGNA primitives The SS-DGNA service primitives at the Affected user MS (FE1) TNSS-SAP are: a) ASSIGN indication; b) ASSING response; c) DEASSIGN indication; d) DEASSING response; e) INTERROGATE GROUP request; f) INTERROGATE GROUP indication; g) INTERROGATE MS GROUPS indication; h) INTERROGATE MS GROUPS response.
