IEC 61850-80-6:2026, which is a technical specification, provides a comprehensive overview of the various aspects that need to be considered while using IEC 61850 for information exchange between power system automation equipment and control or maintenance centres or other system level applications. This document:
defines use cases and communication requirements that require an information exchange between power system automation equipment and control or maintenance centres;
describes the usage of the configuration language of IEC 61850‑6;
gives guidelines for the selection of communication services and architectures compatible with IEC 61850;
describes the engineering workflow;
introduces the use of a Proxy/Gateway concept;
describes the links regarding the Specific Communication Service Mapping (SCSM);
defines the abstract conformance test cases that build the basis for the conformance test procedures elaborated by the UCAIug Testing Sub Committee.
This document does not define constraints or limitations for specific device implementations. There is no specific clause for cyber security, which is tackled when it is necessary. The model for IEC TS 61850-80-6 provides security functions based upon the security threats and security functions found in IEC TS 62351-1 and IEC TS 62351-2. This document touches on several security aspects with the following basic assumptions:
Information authentication and integrity (e.g., the ability to provide tamper detection) is needed.
In case of operational issues, encryption (to achieve confidentiality) is optional. This typically applies for GOOSE and SV messages in the power utility automation system LAN.
End-to-end information authentication and integrity methods, regardless of information hierarchies, need to be provided. The typical method to provide this security function is through some type of information/message authentication code. IEC 62351-4 and IEC 62351-9 describe how authentication and integrity is achieved for IEC 61850-8-1. IEC 62351-4 provides means to ensure end-to-end data integrity through Proxy/Gateways.
Beneath information authentication and integrity, information availability is an important aspect for telecontrol. This document provides redundancy architectures to enhance the availability of information in control and maintenance centres

The stage 2 description identifies the functional entities involved in the ANF and the information flows between them. And the stage 3 description of ANF-ISIIC specifies its protocol. NOTE 1: According to Recommendation ITU-T I.130 [i.4], the stage 3 description of a bearer or tele-service addresses the network implementation aspects. Consequently, it comprises two steps: the specifications of all protocols at the various reference points involved in any of the service procedures (notably the service operation) are the first step of the stage 3 description, and the specifications of the functions of the corresponding network entities are its second step. NOTE 2: The SDL diagrams have not been provided since they can be derived from the specification of the functional entity actions in the stage 2 description. The present document applies to TETRA networks which support inter-TETRA individual calls. More specifically, it applies to their Circuit Mode Control Entities (CMCE), as defined in clause 14.2 of ETSI EN 300 392-2 [1], and to their ANF-ISIIC entities defined in the stage 2 description. The relation between the ANF-ISIIC and the transport layer protocol is described in the General Design documents [2], [i.10] and [i.11].

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 upon which the definition of each ANF is based; and
• the security related functions over the ISI.
The specification of the general transport layer independent protocol mechanism 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 end-to-end encryption over the ISI. Besides the ISI general design, the present sub-part, interworking at the Inter-System Interface comprises the following other sub-parts:
• General design, PSS1 over E.1 [3];
• General design, SIP/IP [4];
• Transport layer independent Additional Network Feature Individual Call (ANF-ISIIC) [5];
• Transport layer independent Additional Network Feature Group Call (ANF-ISIGC) [6];
• Transport layer independent Additional Network Feature Short Data Service (ANF-ISISDS) [7];
• Transport layer independent Additional Network Feature, Mobility Management (ANF-ISIMM) [8]; and
• Generic Speech Format Implementation [9].

IEC PAS 61850-90-19:2026 document takes over the IEC 61850 data model specific definitions such as the definition of permissions and their assignment to roles from IEC 62351-8.
The general requirements for Role-Based Access Control (RBAC) are defined in IEC 62351-8. This part of IEC 61850, which is a Publicly Available Specification, applies those requirements to the IEC 61850 environment, including the RBAC modelling considerations, the impacts on IEC 61850 models and protocols, and the resulting engineering process requirements.
Additionally, the binding of permissions to objects is defined to allow an interoperable implementation regarding the semantic of roles. This is achieved by an assignment to unique data objects based on the SCL description. Note that for this, IEC 61850-6:2009+AMD1:2018+AMD2:2024 is a prerequisite as it defined a unique identification of objects in SCL.

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.

The present document defines the mobility management of interworking at the Inter-System Interface (ISI) for Terrestrial Trunked Radio (TETRA) system supporting Voice plus Data (V+D). The TETRA V+D Inter-working - basic operation part defines the Inter-System Interface (ISI) between the SwMIs as specified in the following sub-parts:
• Transport layer independent, General design [i.5].
• General design, PSS1 over E.1 [13].
• General design, SIP/IP [i.6].
• Transport layer independent Additional Network Feature Individual Call (ANF-ISIIC) [9].
• Transport layer independent Additional Network Feature Group Call (ANF-ISIGC) [10].
• Transport layer independent Additional Network Feature Short Data Service (ANF-ISISDS) [i.2].
• Transport layer independent Additional Network Feature, Mobility Management (ANF-ISIMM) (the present document).
• Generic Speech Format Implementation [i.4].
NOTE: These TSs are produced in analogy with Recommendation ITU-T I.130 [4].
The present document contains the ANF-ISIMM part. The ANF-ISIMM part defines additional Mobility Management (MM) services to the SwMIs. If supported, the ANF-ISIMM services complement the intra-SwMI-MM, authentication and key management services. In support of these, the ANF-ISIMM enables the invocation and operation of these services between the SwMIs over the ISI. Thus, ANF-ISIMM offers the following services:
• Migration and restricted migration.
• Individual subscriber and group profile update.
• Supplementary Service profile update.
• De-registration.
• Group attachment/detachment.
• Linked group attachment/detachment.
• Individual subscriber and group database recovery.
• Authentication, one-directionally or mutually between the individual subscriber and the home SwMI.
• Over-The-Air-Re-keying (OTAR) for Static Cipher Key (SCK) generation and SCK delivery.
For the following service are only included in the stage 1 descriptions:
• Group Linking/unlinking.
• GTSI attachment/detachment to a linking participating group from another SwMI.
