1 Scope
The present document defines the general aspects of interworking at the Inter-System Interface (ISI) for Terrestrial
Trunked Radio (TETRA) system supporting Voice plus Data (V+D). Those specify the general concepts which are the
basis of the ISI operation between TETRA systems. It introduces the Additional Network Features (ANFs) used at
the ISI, and specifies:
- the general protocol mechanism, called ISI Generic Functional Protocol (ISI GFP), upon which the definition
of each ANF is based; and
- the security requirements for the ISI.
The ISI GFP specification applies to any TETRA Switching and Management Infrastructure (SwMI) which supports the
ISI. The security requirements for the ISI only apply to SwMIs which support authentication or encryption over the ISI.
Besides the ISI general design, the present document, interworking at the Inter-System Interface comprises the
following other sub-parts:
- Additional Network Feature - ISI Individual Call (ANF-ISIIC);
- Additional Network Feature - ISI Group Call (ANF-ISIGC);
- Additional Network Feature - ISI Short Data service (ANF-ISISDS); and
- Additional Network Feature - ISI Mobility Management (ANF-ISIMM).

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ISO/IEC 11582 [13] and the following
apply:
call independent: property of information which is conveyed across the Q reference point in a message that does not
use a call reference which has an associated user-information connection
NOTE: In TETRA standards, the term call unrelated is used with the same meaning as call independent.
call independent signalling connection: signalling connection established between ANF-ISI entities located in
different Switching and Management Infrastructures that does not have an associated user-information connection
call unrelated: See the definition of the term "call independent".
co-ordination Function: entity which provides co-ordination between different ANF-ISI entities, ROSE, SSE and
GFT Control for different TETRA basic and supplementary services
destination SwMI: Switching and Management Infrastructure where the receiving ANF-ISI entity is located (in the
context of a single one-way exchange of information between two ANF-ISI entities located in different Switching and
Management Infrastructures)
Generic Functional Transport Control (GFT Control) entity: entity that exists within a Switching and Management
Infrastructure and provides a range of services to the ANF-ISI entities and ROSE via the co-ordination Function
NOTE: The services are defined in clause 6 of ISO/IEC 11582 [13].
group attached SwMI: Switching and Management Infrastructure different from the home SwMI of the group
considered in which at least one individual subscriber member of the group is attached to that group
Group TETRA Subscriber Identity (GTSI): TETRA Subscriber Identity assigned to a group
home SwMI: Switching and Management Infrastructure in which the subscription of a given user is registered
NOTE: That user is defined as being a subscriber (see below the definition of that term).
invocation: action taken by the user or by t

1 Scope
The present document defines the general aspects of interworking at the Inter-System Interface (ISI) for Terrestrial
Trunked Radio (TETRA) system supporting Voice plus Data (V+D). Those specify the general concepts which are the
basis of the ISI operation between TETRA systems. It introduces the Additional Network Features (ANFs) used at
the ISI, and specifies:
- the general protocol mechanism, called ISI Generic Functional Protocol (ISI GFP), upon which the definition
of each ANF is based; and
- the security requirements for the ISI.
The ISI GFP specification applies to any TETRA Switching and Management Infrastructure (SwMI) which supports the
ISI. The security requirements for the ISI only apply to SwMIs which support authentication or encryption over the ISI.
Besides the ISI general design, the present document, interworking at the Inter-System Interface comprises the
following other sub-parts:
- Additional Network Feature - ISI Individual Call (ANF-ISIIC);
- Additional Network Feature - ISI Group Call (ANF-ISIGC);
- Additional Network Feature - ISI Short Data service (ANF-ISISDS); and
- Additional Network Feature - ISI Mobility Management (ANF-ISIMM).

use a call reference which has an associated user-information connection
NOTE: In TETRA standards, the term call unrelated is used with the same meaning as call independent.
call independent signalling connection: signalling connection established between ANF-ISI entities located in
different Switching and Management Infrastructures that does not have an associated user-information connection
call unrelated: See the definition of the term "call independent".
co-ordination Function: entity which provides co-ordination between different ANF-ISI entities, ROSE, SSE and
