SIST EN 300 947 V6.0.1:2003 is the Slovenian adoption of ETSI EN 300 947 V6.0.1 for the GSM digital cellular telecommunications system, Release 1997. It specifies the Stage 3 procedures for the enhanced Multi-Level Precedence and Pre-emption service (eMLPP), so it tells network and mobile station implementers how priority is signalled and handled on the radio interface.
What does SIST EN 300 947 V6.0.1:2003 specify?
SIST EN 300 947 V6.0.1:2003 specifies the radio-interface procedures at reference point Um for eMLPP. It covers normal operation, invocation, registration and interrogation of the supplementary service.
The standard treats provision and withdrawal as administrative matters between the mobile subscriber and the service provider, with no radio-interface signalling for those actions. That matters in practice because the document is about how the network and handset exchange messages, not about commercial service ordering.
The document is organized into:
- Scope
- References
- Definitions and abbreviations
- Clause 4 on eMLPP procedures
- Annex A with change request history

What are the key requirements of SIST EN 300 947 V6.0.1:2003?
SIST EN 300 947 V6.0.1:2003 defines how priority is carried in calls, how the default priority is registered, and how the service is queried. The practical focus is on which messages carry the priority level and when the network or mobile station may override or report it.
Call handling in normal operation
- Mobile originated calls - Clause 4.1.1 lets the mobile station indicate the priority of a call. If the user does not select a priority, or the mobile station is not compatible, the network applies the default priority stored in the VLR. In practice, handset and network software need to carry the requested or default priority through service request, authentication, ciphering and call setup.
- Mobile terminated calls - Clause 4.1.2 requires the paging message and the SETUP message to include the call priority. This lets the called mobile station decide how to handle the incoming call, especially where priority affects the response to paging.
- Called party pre-emption - Clause 4.1.3 covers the case where the called subscriber has both eMLPP and Call Waiting (CW). A compatible mobile station can accept the waiting call and place the ongoing call on hold, or release the ongoing call if hold fails. In practice, this is the behavior that allows a higher-priority incoming call to replace a lower-priority ongoing one.
Group and broadcast calls
- VGCS and VBS calling mobile station - Clause 4.1.4 applies eMLPP to Voice Group Call Service (VGCS) and Voice Broadcast Service (VBS). The calling mobile station may request a priority, but the Group Call Reference (GCR) can provide the priority used by the network. Implementers need to check which priority applies to the dedicated link and to the group or broadcast call itself.
- VGCS and VBS called mobile stations - Clause 4.1.5 requires the related notification messages to carry the group or broadcast call reference with the priority level. That means the handset must treat the notification according to the VGCS or VBS procedures while also recognizing the call priority.
Service management
- Registration - Clause 4.2 requires the registration request to include the SS-Code of eMLPP and the default priority level. If the registration succeeds, the network returns the accepted default priority level; if not, it returns an error. This is the mechanism that stores the subscriber’s default calling priority in the network.
- Erasure - Clause 4.3 says a previous registration can be replaced by registering a new default priority level, or erased when the supplementary service is withdrawn. In practice, the last valid registration controls the stored default priority.
- Activation, deactivation and interrogation - Clause 4.4 states that activation and deactivation do not apply to eMLPP. Clause 4.5 allows the subscriber to query the maximum priority level available and the current default priority level, with the response carrying SS-Status when appropriate. This gives operators and users a clear way to verify what priority the network has stored and allows the subscriber to check the usable range.
What terms does SIST EN 300 947 V6.0.1:2003 define?
SIST EN 300 947 V6.0.1:2003 uses a small set of service and network terms that are central to its procedures.
- eMLPP (enhanced Multi-Level Precedence and Pre-emption) - The supplementary service covered by the standard, used to assign and signal call priority.
- MLPP (Multi-Level Precedence and Pre-emption) - The underlying precedence and pre-emption concept that eMLPP extends.
- VGCS (Voice Group Call Service) - A group-call service for which eMLPP priority can be applied.
- VBS (Voice Broadcast Service) - A broadcast-call service for which eMLPP priority can be applied.
- Default priority level - The priority value stored in the network and used when the user does not select one or the mobile station is not compatible.
- SS-Code - The supplementary service code included in the registration request for eMLPP.
- SS-Status - The status parameter returned by the network during interrogation of the service.
Who uses SIST EN 300 947 V6.0.1:2003?
SIST EN 300 947 V6.0.1:2003 is used by GSM network operators, mobile network engineers, handset and protocol-stack implementers, and test labs. They use it to implement and verify priority handling for call setup, call waiting, paging, registration and interrogation.
It is also useful for quality managers and buyers assessing whether equipment supports eMLPP behavior on the radio interface. In practice, they look for correct handling of priority levels in ordinary calls, VGCS and VBS, and in subscriber service data.
What changed in SIST EN 300 947 V6.0.1:2003 from the previous edition?
SIST EN 300 947 V6.0.1:2003 is identified in the history as the V6.0.1 publication following ETS 300 947 V6.0.0. Annex A records the earlier draft and approval milestones leading up to this version.

What does the SIST EN 300 947 V6.0.1:2003 document contain?
The document contains signalling sequence figures for mobile originated calls, mobile terminated calls, called party pre-emption, VGCS and VBS call establishment, notification to called mobile stations, registration of the default priority level, and interrogation of the maximum and default priority levels. These figures are the main implementation aid for protocol designers and testers.
It also includes clause text explaining how the priority level is carried in service request, paging, SETUP, CALL_PROCEEDING, CONNECT and notification messages. That helps engineers map the service rules into actual GSM signalling behavior.
Annex A provides the change request history, which is useful when tracking how the specification evolved through the GSM release process.
