1 Scope
This ETS defines the Terrestrial Trunked Radio system (TETRA) supporting Voice plus Data (V+D). It
specifies:
- general design aspects (e.g. reference points, numbering and addressing, or protocol architecture);
- the interworking between TETRA networks;
- the interworking of TETRA networks with other networks, via gateways;
- the supplementary services applicable to the basic TETRA tele- or bearer services.
The TETRA V+D interworking - basic operation part defines the interworking between TETRA networks
over the corresponding interface: the Inter-System Interface (ISI). It comprises the following subparts:
- ISI general design;
- Additional Network Feature - ISI Individual Call (ANF-ISIIC);
- Additional Network Feature - ISI Group Call (ANF-ISIGC);
- Additional Network Feature - ISI Short Data service (ANF-ISISD);
- Additional Network Feature - ISI Mobility Management (ANF-ISIMM);
- 8 kbit/s encoding of user information at the ISI.
This ETS is the ANF-ISIGC subpart.
In analogy with CCITT Recommendations I.130 [19], the stage one, stage two and stage three of the three
level structure is used to describe the TETRA Inter-System Interface services as provided by European
Private or Public Trunked Radio System operators:
- Stage 1, is an overall service description, from the service subscriber's and user's standpoint;
- Stage 2, identifies the functional capabilities and information flows needed to support the services
described in stage 1; and
NOTE: The information flows in stage 2 have been drawn as Message Sequence Charts
(MSC). Therefore PISN basic call information flows are also shown together with the
ANF-ISIGC information flows.
- Stage 3, defines the signalling system protocols and switching functions needed to implement the
services described in stage 1.
This ETS details the Interworking Basic Operation of the Terrestrial Trunked Radio system (TETRA).
Specifically this subpart details the stage 1 aspects (overall service description) of the ANF-ISIGC as seen
from the TETRA Switching and Maintenance Infrastructure point of view at the Inter-System Interface
(ISI). It details the stage 2 aspects (functional partitioning) of ANF-ISIGC which includes the identification
of the functional entities and the flows between them, and finally it details the stage 3 signalling protocols
for the ANF-ISIGC services, i.e. the protocols at the relevant reference points between the functional
entities defined in stage 2.
The ANF-ISIGC service specifies:
- TETRA Group Call Clear Speech over the ISI, acknowledged and unacknowledged;
- TETRA Group Call End-to-End Encrypted Speech over the ISI;
- TETRA Group Call Circuit Mode one slot data over the ISI;
- TETRA Group Call Circuit Mode one slot End-to-End Encrypted data over the ISI;
- TETRA Group Call Circuit Mode N x 2,4 kbit/s, N x 4,8 kbit/s or N x 7,2 kbit/s data, with N = 2, 3
or 4;
- TETRA Group Call Circuit Mode N x 2,4 kbit/s N x 4,8 kbit/s or N x 7,2 kbit/s End-to-End Encrypted
data, with N = 2, 3 or 4.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS the following terms and definitions apply:
controlling SwMI: Switching and Management Infrastructure(SwMI) which sets up and maintains a call
between two or more SwMIs.
foreign user: user who is not a member of the called group.
group home: home of the GTSI, i.e. the SwMI where the network code (MNC) is equal to that of the
group (GTSI).
individual home: home of the MS's ITSI, i.e. the SwMI where the network code (MNC) is equal to that of
the individual subscriber (ITSI).
linking controlling SwMI: SwMI that controls the linking of one of its own groups to one or more groups
from other SwMIs. The group linking controlling SwMI is the home SwMI of the linked groups.
linking home SwMI: see linking controlling SwMI.
linking participating SwMI: SwMI that participates in the group linking by linking (joining) one group to
the group linking.
linked group: linking of one or more group identities from different TETRA SwMIs which forms a
multigroup across several TETRA SwMIs and where one of these is designated to be the home of the
linked group.
originating SwMI: SwMI from where the call originates, i.e. where the initial call set-up is detected. Once
the calling user has been connected, the originating SwMI becomes a participating SwMI.
participating SwMI: SwMI only participates in the call without controlling it and will always be the end
point of the call, i.e. where the call is terminated.
Page 14
ETS 300 392-3-3: March 2000
served SwMI: SwMI that is involved in a group call either as the originating SwMI, the controlling SwMI or
as the participating SwMI, hence utilizing the ANF-ISIGC service.
transit SwMI: within the context of a call, any SwMI through which the call passes, excluding the
originating SwMI, controlling SwMI or participating SwMI(s), is known as a transit SwMI. No members of
the active call shall terminate at a transit SwMI.
visited SwMI: TETRA network which MNI is not equal to the user's MNI.

4 ANF-ISIGC stage 1 specification
4.1 Description
4.1.1 General description
ANF-ISIGC enables point to multipoint calls to be set-up between TETRA users located in more than one
TETRA Switching and Management Infrastructure (SwMI), over the Inter-System Interface (ISI). In support
of this, the ANF-ISIGC which operates at the ISI, shall detect a request from the originating SwMI for
establishing one point to multipoint TETRA group call service between two or more TETRA SwMIs.
For originating requests the ANF-ISIGC provides access to the user profiles for both the calling individual
TETRA user as well as it provides access to the user profile of the called TETRA group. The information
is used for routeing purposes and call contention checking. ANF-ISIGC also forwards the group call
indication to the participating TETRA SwMIs.
For the duration of the call, the ANF-ISIGC shall handle transmission control signalling from all
participating TETRA SwMIs. This is to ensure that transmission granting is only given to one of the
individual TETRA users participating in the group call according to the point to multipoint TETRA call
procedures defined in ETS 300 392-2 [3]. Additionally, ANF-ISIGC shall participate in call restoration when
a TETRA user in the group call migrates to another TETRA SwMI.
ANF-ISIGC may also be used to transport group related supplementary services between TETRA SwMIs.
4.1.2 Qualifications on applicability to TETRA basic services
ANF-ISIGC is applicable to the following point to multipoint basic services as defined in
ETS 300 392-2 [3]:
- point to multipoint one slot TETRA clear mode speech;
- point to multipoint one slot TETRA end-to-end encrypted speech;
- point to multipoint one slot 2,4 kbit/s, 4,8 kbit/s, or 7,2 kbit/s TETRA circuit mode data;
- point to multipoint end-to-end encrypted one slot 2,4 kbit/s, 4,8 kbit/s, or 7,2 kbit/s TETRA circuit
mode data;
- point to multipoint N x 2,4 kbit/s, N x 4,8 kbit/s, or N x 7,2 kbit/s TETRA circuit mode data, with
N=2,3or4;
- point to multipoint end-to-end encrypted N x 2,4 kbit/s, N x 4,8 kbit/s, or N x 7,2 kbit/s TETRA circuit
mode data, with N = 2, 3 or 4.

ANF-ISIGC shall be permanently available or controlled by provision/withdrawal.
