SIST EN 300 954 V7.0.1:2003 is the Slovenian identical adoption of ETSI EN 300 954 Version 7.0.1 for GSM Multi Party (MPTY) supplementary services. It specifies the Stage 3 procedures at the radio interface for setting up, holding, splitting, retrieving and extending a MultiParty call in a digital cellular telecommunications system (Phase 2+), so it is mainly for network and terminal implementers. The document links those procedures to GSM call control and supplementary-service signalling, which matters when interoperable behaviour is needed between the mobile station and the network.
What does SIST EN 300 954 V7.0.1:2003 specify?
SIST EN 300 954 V7.0.1:2003 specifies the procedures used at the radio interface, at reference point Um, for normal operation and invocation of MultiParty supplementary services. It focuses on the MultiParty service (MPTY) and organizes the subject into service setup, active-call handling, held-call handling, mixed single-call and MPTY handling, extra party addition, auxiliary states, and operation limits.

The front matter gives the scope, references and abbreviations, and clause 1 contains the operational procedures. Annex A gives the change request history for the specification.
What are the key requirements of SIST EN 300 954 V7.0.1:2003?
The core of SIST EN 300 954 V7.0.1:2003 is the signalling logic for MPTY operations on the radio interface. In practice, the standard tells implementers how the mobile station and network exchange FACILITY messages, how they identify the affected call with the transaction identifier (TI), and how they handle timeouts and notifications.
Service setup and invocation
Clause 1.1 defines how the served mobile subscriber starts an MPTY call by sending a FACILITY message with BuildMPTY. The network normally joins the existing active and held calls, or returns an error if it cannot. The mobile station runs T(BuildMPTY), so an implementation needs clear timeout handling and user feedback when the network does not answer in time.
Active and held MPTY control
Clause 1.2.1 lets the served mobile subscriber put the MPTY call on hold with HoldMPTY, create a private communication with one remote party using SplitMPTY, disconnect a remote party, or clear the whole conference. Clause 1.3.1 provides the corresponding RetrieveMPTY procedure for a held MPTY call. These procedures matter because they let a handset move between conference, private call and held states without losing the signalling context.
Remote-party behaviour and notifications
Clause 1.2.2 describes what remote parties can do during an active MPTY call, including releasing themselves from the conference or placing their connection on hold. The network forwards held or retrieved indications to the served subscriber, and it sends MPTY notifications only when the remote party’s mobile station has provided a non-zero SS Screening indicator. That makes notification behaviour dependent on the signalling capability of the participating mobiles.
Mixed single-call and MPTY use
Clause 1.4 covers a served mobile subscriber who has both an MPTY call and a separate single call. It allows the subscriber to disconnect either call, disconnect both, add the single call into the conference with BuildMPTY, or alternate between the single call and the MPTY call by using HoldMPTY and RetrieveMPTY. This is the part to read when designing handsets that must manage several simultaneous call contexts.
State handling and limits
Clause 1.6 introduces auxiliary states for MPTY: Idle, MPTYrequest, CallinMPTY and Splitrequest. It also shows that not every state combination is allowed, such as trying to split a call while it is held. Clauses 1.7 and 1.8 add two practical limits: activation, deactivation, registration, erasure and interrogation are not applicable, and BuildMPTY, SplitMPTY, HoldMPTY and RetrieveMPTY cannot be used at the same time or mixed together in one message.
What terms does SIST EN 300 954 V7.0.1:2003 define?
- MultiParty service (MPTY) - The supplementary service that connects several calls into one shared conference.
- FACILITY - The layer 3 message used to carry supplementary-service invoke, result and error components.
- Transaction identifier (TI) - The identifier that ties a supplementary-service action to the active or held call it affects.
- BuildMPTY - The invoke component used to join calls into a MultiParty call.
- HoldMPTY - The operation that places the MPTY connection on hold.
- RetrieveMPTY - The operation that brings a held MPTY call back to the active state.
- SplitMPTY - The operation that separates one remote party for private communication.
- SS Screening indicator - A signalling indicator from the remote party’s mobile station that controls whether MPTY notifications are sent.
Who uses SIST EN 300 954 V7.0.1:2003?
SIST EN 300 954 V7.0.1:2003 is used by GSM network engineers, mobile station and handset protocol developers, and test laboratories that verify supplementary-service behaviour. It is also relevant for quality managers and buyers who need to confirm that a product supports MPTY signalling in a Release 1998 GSM environment. The standard is most useful for implementation, interoperability testing and protocol conformance work.
What changed in SIST EN 300 954 V7.0.1:2003 from the previous edition?
The document history shows that version 7.0.0 upgraded specification version 6.0.0 to Release 1998. Version 7.0.1 is recorded as a publication update to the text and figures.

What does the SIST EN 300 954 V7.0.1:2003 document contain?
The document contains the procedure descriptions for starting, holding, retrieving and splitting MPTY calls, plus the rules for adding extra remote parties and managing mixed MPTY and single-call situations. It includes message-sequence figures for the key FACILITY exchanges and the notification flows toward remote parties. It also defines the auxiliary-state model used with MPTY and an informative annex with the change request history. These elements are the parts most often used for implementation, interoperability testing and protocol review.
