SIST EN 300 392-3-5 V1.2.1:2006

• Abstract:

  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:; • Additional Network Feature - Inter-System Interface General Description (ANF-ISIGD);; • Additional Network Feature - Inter-System Interface Individual Call (ANF-ISIIC);; • Additional Network Feature - Inter-System Interface Group Call (ANF-ISIGC);; • Additional Network Feature - Inter-System Interface Short Data Service (ANF-ISISD);; • Additional Network Feature - Inter-System Interface Mobility Management (ANF-ISIMM).; NOTE: These ENs are produced in analogy with the ITU-T Recommendation I.130 [8].; 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;; • profile update;; • de-registration;; • group attachment/detachment;; • individual subscriber and group database fault 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 only the stage 1 descriptions are included:; • linking/unlinking of groups.

SIST EN 300 392-3-5 V1.2.1:2006 is the Slovenian adoption of ETSI EN 300 392-3-5 Version 1.2.1 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D). It specifies Additional Network Feature for Mobility Management (ANF-ISIMM) at the Inter-System Interface (ISI), so different SwMI roles can handle migration, restricted migration, authentication, Over-The-Air-Re-keying (OTAR), database recovery and group-related mobility tasks. It is aimed at the people who design, operate and test TETRA interworking between home, visited and previous visited network roles.

What does SIST EN 300 392-3-5 V1.2.1:2006 specify?

SIST EN 300 392-3-5 V1.2.1:2006 specifies the mobility management part of TETRA interworking at the ISI for V+D systems. In practice, it defines how subscriber and group mobility information is exchanged between SwMI roles so that service follows the user when the subscriber moves across systems.

The document is organized around:

• Clause 1-4: scope, references, definitions, abbreviations and overview
• Clause 5: the generic ANF-ISIMM stage 1 service model
• Clause 6-18: stage 1 descriptions for migration, restricted migration, RSI, de-registration, profile update, SS-profile update, authentication, OTAR, IDR, group attachment, group detachment, GDR and group linking/unlinking
• Clause 19-32: stage 2 information flow sequences for the same services
• Clause 33-37: stage 2 flow definitions, stage 3 encoding requirements, stage 3 procedures and general ANF-ISIMM service and protocol principles
• Annex B: recovery procedures for HMM recovery and VMM recovery

Annex	What it covers
B	HMM recovery and VMM recovery procedures for home, visited and previous visited SwMI MMs

Clause 4 also sets the practical frame for use of the feature: provision and withdrawal are by pre-arrangement between SwMI operators, activation follows provision, deactivation follows withdrawal, and testing is intended at the ISI interface.

What are the key requirements of SIST EN 300 392-3-5 V1.2.1:2006?

SIST EN 300 392-3-5 V1.2.1:2006 is mainly a service-control standard. It tells each side of the inter-system relationship what to send, when to invoke a service, and how to react to acceptance, rejection or recovery.

Service access, roles and testability

Clause 5 states that ANF-ISIMM is a SwMI V+D layer 3 network service provider for SwMI MMs. It distinguishes the home SwMI MM, visited SwMI MM and previous visited SwMI MM, which matters because each role has a different duty in migration, recovery and cleanup.

Clause 4.3 says ANF-ISIMM shall be testable over the ISI, with testing intended at the interface. For implementers, that means the interoperability point is the interface behavior, not just internal database logic.

Migration and restricted migration

Clause 6 makes migration a mandatory service for SwMI MMs that support ANF-ISIMM. Migration applies when the subscriber MNI and the visited SwMI MNI do not match, and it can use either pre-defined migration profiles or migration profile exchange. Practically, this is the core handover of subscriber context between systems.

Clause 7 defines restricted migration as an optional service that can only be used if both home and visited SwMI MMs support it. It allows the subscriber to migrate with the right to make and receive circuit switched emergency calls, so systems need a controlled fallback path when full migration is not granted.

Subscriber data cleanup and de-registration

Clause 8 defines RSI as a mandatory service when a previous visited SwMI exists for the subscriber. It removes the old subscriber information from the visited side after migration, which matters because stale records can create wrong routing, wrong service state or security issues.

Clause 9 defines de-registration for a migrated individual subscriber. After de-registration, the subscriber is no longer offered service in the visited SwMI, so implementations must release the visited-side state cleanly.

Profile synchronization

Clause 10 defines profile update as the home SwMI MM updating the basic migration profile at the visited SwMI where the subscriber is migrated or where the group is attached. Clause 11 does the same for SS-migration profiles. These clauses matter because the visited system must have current service, group and supplementary service data before calls and supplementary functions can work correctly.

Authentication and OTAR

Clause 12 defines authentication between the migrated individual subscriber and the visited or home SwMI MM. A prerequisite is that the second stage algorithms TA12 and TA22 are common for the migrating individual subscriber and the visited SwMI. In practice, authentication is only possible when both sides share the required algorithm support.

Clause 13 defines OTAR for assignment of Static Cipher Key (SCK) material to the migrated individual subscriber. The clause uses SCKN, SCK-VN and sealed-key handling, so implementers have to manage key identity, versioning and transport consistently when generating or delivering keys.

Database recovery and group handling

Clause 14 defines Individual subscriber Database Recovery (IDR) across SwMIs. It uses virtual migration or restricted migration, virtual RSI and iteration until completion. Clause 17 does the same for Group Database Recovery (GDR). These clauses matter when a database has to be rebuilt or synchronized after loss, move or partial failure.

Clauses 15-18 cover group attachment, group detachment and group linking/unlinking across the ISI. Clause 15 and clause 16 depend on ANF-ISIGC support, while clause 18 allows linked groups to act as a combined group call. In practice, group behavior must stay aligned with the subscriber's movement and the operator's group policy.

Stage 2 and stage 3 behavior

Clause 19 starts the stage 2 specification, with information flow diagrams and sequences for normal and exceptional operation. Clause 33 defines the stage 2 information flows, and clauses 34-37 define the stage 3 PDUs, information elements, procedures and general protocol principles. That means the standard covers both the service behavior and the message encoding needed for interworking.

What terms does SIST EN 300 392-3-5 V1.2.1:2006 define?

• ANF-ISIMM - Additional Network Feature for Mobility Management; the ISI service that carries mobility, authentication, OTAR and recovery functions between SwMI roles.
• RSI - Removal of Subscriber Information; the service that removes old subscriber information from the previous visited SwMI after migration.
• SCK - Static Cipher Key; the cipher key assigned through OTAR to the migrated individual subscriber.
• SCKN - Static Cipher Key Number; the identifier for the position of an SCK within the key set.
• SCK-VN - Static Cipher Key Version Number; the identifier that distinguishes one SCK version from another.
• APDU - Application Protocol Data Unit; the protocol data unit used in the stage 3 encoding rules.
• visited SwMI - the SwMI where the I-VDB, and optionally the G-VDB and VAC, reside, and whose MNI differs from the home SwMI.

Who uses SIST EN 300 392-3-5 V1.2.1:2006?

SIST EN 300 392-3-5 V1.2.1:2006 is used by TETRA network operators, system integrators and radio engineers who need mobility management to work across system boundaries. It is also relevant to operators who agree service provision and withdrawal, because the standard says ANF-ISIMM is provided by pre-arrangement between SwMI operators.

It is used by engineers who implement the home, visited and previous visited SwMI roles, especially for migration, authentication, OTAR, subscriber database recovery and group service behavior. Test teams use it at the ISI interface, since the standard explicitly places testing there. Buyers and quality managers use it to check whether a system supports the required ANF-ISIMM service set and the associated interworking behavior.

Which standards are used with SIST EN 300 392-3-5 V1.2.1:2006?

• ETSI EN 300 392-2 - supplies the neighbour cell broadcast service referenced for speeding up migration and restricted migration.
• ETSI EN 300 392-7 - supplies the TA12, TA22, TA51 and TA52 prerequisites used for authentication and OTAR.
• ETSI TS 101 747 - names IP Interworking, which appears in the reference list for related packet interworking.
• ITU-T Recommendation I.130 - provides the service description model used for the stage 1 structure of this document.
• ITU-T Recommendation Q.931 - provides the basic call control layer 3 specification listed among the references.
• ANF-ISIGD, ANF-ISIIC, ANF-ISIGC and ANF-ISISD - the related ISI parts named in the scope, covering the general ISI description, individual call, group call and short data service.

What does the SIST EN 300 392-3-5 V1.2.1:2006 document contain?

The document contains service architecture figures, stage 1 service descriptions, stage 2 information flow sequences and stage 3 message encoding rules. It also includes SDL-style dynamic descriptions for the service behavior, including normal and exceptional operation.

Clause 33 defines the stage 2 information flows for messages such as AUTHENTICATION DEMAND, MIGRATION, OTAR-KEY DEMAND, PROFILE UPDATE, REMOVE SUBS and the related responses, rejects and completions. Clause 34 gives the PDU description tables and the information element encoding requirements that implementers use to build interoperable messages.

Clause 35 describes procedures for the visited and home SwMI roles, including the conversions between primitives and PDUs and the correspondence between them. Clause 36 adds ANF-ISIMM-specific handling for the ISI GFP connection, queuing, ROSE and invoke-ID allocation. Clause 37 sets general protocol principles such as inclusion of Short Subscriber Identity, PISN number exchange, timers, bundling and exceptional procedures.

Annex B adds recovery procedures for HMM recovery and VMM recovery, including the roles of the home, visited and previous visited SwMI MMs.
