SIST EN 301 361-2:2000 is the Slovenian adoption of ETSI EN 301 361-2, Part 2 of the ISDN Mobility protocol Interworking specification Profile (IMIP). It specifies how a Digital Enhanced Cordless Telecommunications (DECT) Fixed Part (FP) interworks with an Integrated Services Digital Network (ISDN) interface to support Global System for Mobile communications (GSM) mobility. In practice, it is for DECT/ISDN equipment that must carry GSM identities, mobility management, and call control across the DECT air interface.

What does SIST EN 301 361-2:2000 specify?

SIST EN 301 361-2:2000 specifies technical requirements for DECT FPs that connect, through an ISDN interface, to a network supporting terminal mobility. The document covers the DECT/ISDN interworking procedures needed for GSM support, using the enhanced Digital Subscriber Signalling No. 1 (DSS1) protocol on the alpha interface.

The scope is limited to the interworking profile itself. The ISDN network-layer requirements are taken from the referenced alpha-interface specification, and the DECT network-layer baseline follows the Generic Access Profile (GAP) unless this part adds or changes something.

The document is organized into these main clauses:

• 1 Scope
• 2 References
• 3 Definitions, symbols and abbreviations
• 4 Feature definitions
• 5 General requirements
• 6 Interoperability requirements
• 7 Procedure descriptions
• 8 Message mappings

What are the key requirements of SIST EN 301 361-2:2000?

The standard ties together DECT, ISDN, and GSM at the FP. It defines what the FP has to do for mobility management, call control, identity handling, and message translation so that a DECT user can be handled like a GSM user over ISDN.

Architecture and identity handling

Clause 5 sets the reference configuration and says the profile applies to both basic rate access (BRA) and primary rate access (PRA), in point-to-point and point-to-multi-point cases. That matters because the same profile must work in different access deployments.

Clause 5.3 requires the FP to map the GSM identity to the DECT PP identity. The document assumes a one-to-one relation between IMSI or TMSI and IPUI or TPUI. It also defines the FP-address as a globally unique E.164 number, used when the FP must identify the access point itself, especially in point-to-multi-point operation.

Feature support and status

Clause 6 classifies which features are mandatory, optional, or conditional. It covers network features such as authentication of portable, location registration, identification of portable, network-initiated ciphering, temporary identity assignment, linked temporary identity assignment, and detach. The application feature table adds identification, authentication, location registration/cancellation, outgoing and incoming call, plus optional supplementary service activation and DTMF generation.

That matters because implementers can see which GSM-related functions the FP has to handle and which ones may be optional in a given product.

Mobility management procedures

Clause 7.2 describes the main mobility management procedures. These include identification of PP, authentication of PP, location registration, network-initiated ciphering, temporary identity assignment, linked temporary identity assignment, and detach. The FP must translate between DECT messages and GSM mobility management components, and in several cases it must start timers and return explicit errors if it rejects a request.

Clause 7.4 adds interaction rules. Only one mobility management transaction may be initiated toward the PP at a time, and network-initiated requests may be queued or rejected if another transaction is active. For a buyer or test team, this is the part that affects concurrency and timeout behavior.

Call control and user dialing

Clause 7.3 covers outgoing and incoming calls. The FP does not need to support DECT en-block dialling or overlap receiving, and it should transfer an outgoing SETUP early rather than waiting for more digits. For incoming calls, the FP checks bearer capability and progress information, accepts speech or 3.1 kHz audio, and falls back to a service compatible with GAP.

Clause 7.3.6 also says the FP generates DTMF tones when keypad information requests it. In practice, this affects how supplementary dialing and in-call tones are handled.

Message and information-element mapping

Clause 8 gives the actual mappings between GSM/MM components and DECT messages, and between GSM/DSS1 messages and DECT call control messages. It also defines which information elements are passed transparently and which need special treatment, such as identity type, location area, transaction identifier, and bearer capability. This is the section implementers use to code the protocol translator.

What terms does SIST EN 301 361-2:2000 define?

• DECT access network - The physical entity containing the DECT FP elements and attached to a GSM MSC, used to provide transparent access to GSM services.
• DECT Fixed Part (FP) - The fixed part of the DECT network between the local network and the DECT air interface.
• GSM location area - The area within which a DECT PP can make or receive calls after one location update in the GSM network.
• Public Land Mobile Network (PLMN) - The public land-mobile network operated to provide mobile telecommunication services.
• served user - A DECT PP user who has a subscription with the GSM service provider.
• location registration - The process that determines the PP position to one location area and updates it in the network.
• Temporary Mobile Station Identity (TMSI) - A GSM temporary identity used on the network side for a mobile subscriber.

Who uses SIST EN 301 361-2:2000?

DECT and GSM/ISDN equipment designers use this standard to implement the FP side of the interworking profile. Network engineers use it to understand how identities, mobility procedures, and call control move between the DECT air interface and the GSM/ISDN side.

Test and conformance teams use the procedure descriptions and message mappings to verify interoperability. Buyers and quality managers use it to check whether an access product really supports GSM mobility over ISDN in the way the profile expects.

What does the SIST EN 301 361-2:2000 document contain?

Clause 7 includes sequence diagrams for connection establishment, release, outgoing calls, incoming calls, paging failure, and mobility management transactions. Those diagrams show how the FP coordinates DECT radio procedures with ISDN-side mobility handling.

Clause 8 contains detailed mapping tables for mobility management messages, call control messages, and information elements or parameters. The tables are used for implementation, integration, and interoperability testing because they show how each DECT-side field corresponds to the GSM or DSS1 side.

The document also includes a protocol model, feature-status tables, and a bibliography of related DECT, GSM, ISDN, and testing standards.
