SIST EN 300 918 V7.1.2:2004 is the Slovene adoption of ETSI EN 300 918 V7.1.2 for the Global System for Mobile communications (GSM). It defines the general framework for supplementary services in a GSM Public Land Mobile Network (PLMN), including how they modify basic telecommunication services and how they are used with other networks. In practice, it is the reference for service design, provisioning logic, and user-facing behavior for GSM supplementary services.

What does SIST EN 300 918 V7.1.2:2004 specify?

SIST EN 300 918 V7.1.2:2004 specifies the recommended set of supplementary services that a GSM PLMN should support alongside teleservices and bearer services. It also sets the rules for how those services are described, grouped, provisioned, activated, and applied across different basic services.

The standard says supplementary services covered in GSM 02.04 and the GSM 02.80 series are the basis for GSM service support. It also states that supplementary services not covered there cannot be introduced unilaterally in a GSM PLMN if they require changes to GSM signalling specifications.

Annex B	Change history

What are the key requirements of SIST EN 300 918 V7.1.2:2004?

Supplementary services are attached to basic services

Clause 2.1 states that a supplementary service modifies or supplements a basic telecommunication service. Clause 3.1 adds that it cannot be offered as a standalone service.

For a reader, this means GSM service planning must always start from a basic bearer service or teleservice, then add the supplementary service on top.

Provision and withdrawal follow service-policy rules

Clause 2.1 distinguishes essential (E) supplementary services from additional (A) ones. E-services shall be available in all GSM PLMNs, while A-services may be offered by operators, including internationally by bilateral agreement.

This matters because not every supplementary service is mandatory in every network, so catalogues and roaming offers need to reflect operator policy.

Service control works on basic-service groups

Clause 3.1 says provision and withdrawal apply to all basic services the subscriber has, except for Closed User Group, while registration, erasure, activation, and deactivation apply to one or more groups of basic services. Table 3.2 defines those groups, such as speech, short message service, facsimile services, data, GPRS access, and voice group services.

In practice, provisioning systems should handle grouped service codes, not just individual service instances.

Supported supplementary services are identified in Table 4.1

Clause 4 and Table 4.1 list the supported services, including eMLPP, call deflection, line identity services, call forwarding variants, call waiting, call hold, MultiParty, Closed User Group, Advice of Charge, call barring variants, Explicit Call Transfer, Completion of Calls to Busy Subscribers, Support of Private Numbering Plan, and Calling Name Presentation.

This table is the quick check for whether a service is part of the GSM supplementary-service set covered by the standard.

Line and name identity services are linked to restriction services

Clause 4.1 says a PLMN that supports CLIP shall also support CLIR, and a PLMN that supports CoLP shall also support CoLR. If CLIR or CoLR is not supported, the network shall suppress display of the line identity unless an override capability applies.

Clause 4.2 applies the same idea to CNAP and CLIR. For users, this means privacy-related identity display must follow the paired restriction logic.

Password control is defined for some services

Clause 5 allows some supplementary services, such as Call Barring, to be controlled by a password option. The password is four digits, and the subscriber uses it when performing actions such as registration, erasure, activation, or deactivation.

If the subscriber enters the wrong password more than three times in a row, password-related control is blocked until the service provider re-enables it.

Network processing can accept partial success

Clause 7 explains how the network processes operations that carry basic service information. The network processes the indicated basic service information independently of previous state, and a request can be partly successful if only some parts are applicable.

For implementers, this means the network can accept one part of a combined request and reject another part, so the acknowledgement must reflect that outcome.

Annex A defines where services apply

Annex A maps supplementary services to telecommunication services such as Telephony, Emergency Call, SMS, fax, data, GPRS, PAD/Packet Access, and Voice Group Services.

This is the practical cross-check for service applicability in product design and network configuration.

What terms does SIST EN 300 918 V7.1.2:2004 define?

• Supplementary service - a service that modifies or supplements a basic telecommunication service.
• Provision - making a service available to a subscriber, either generally or after prior arrangement.
• Withdrawal - removing a service from a subscriber’s access, either generally or for an individual subscriber.
• Registration - storing specific information needed so a supplementary service can operate later.
• Activation - enabling a process so a supplementary service can run when needed.
• Deactivation - ending the process that was started by activation.
• Interrogation - a subscriber request for information about the status or data of a supplementary service.
• Invocation - the action that triggers a service, either by the user or automatically by the network.

Who uses SIST EN 300 918 V7.1.2:2004?

GSM PLMN operators use this standard to decide which supplementary services to offer and how to control them. Network and service engineers use it when designing call handling, provisioning, password control, and interworking with PSTN, ISDN, CSPDN, PSPDN, and PDN environments.

Handset and MMI designers use it for subscriber interaction such as keypad control and service feedback. Test and quality teams use it to verify forwarding, barring, identity presentation, and multi-service behavior.

What changed in SIST EN 300 918 V7.1.2:2004 from the previous edition?

The change history shows a series update to version 7.1.2, with the publication version following version 7.1.1. Earlier recorded changes in the series include additions for ECT, VBS, VGCS, eMLPP, UUS, SPNP, Call Deflection, HSCSD, CCBS, Voice Group Call Service, Voice Broadcast Service, CNAP, MSP, removal of designators, a supplementary code for GPRS, and a corrected ECT reference.

Which standards are used with SIST EN 300 918 V7.1.2:2004?

• GSM01.04 - gives the abbreviations and acronyms used in the standard.
• GSM02.01 - sets the general principles for telecommunication services in a GSM PLMN.
• GSM02.02 and GSM02.03 - define bearer services and teleservices that supplementary services build on.
• GSM02.30 - covers the MMI of the Mobile Station and the control procedures used for subscriber input.
• GSM02.67, GSM02.81 to GSM02.88, GSM02.91, GSM02.93, GSM02.95, GSM02.96 - provide the stage 1 descriptions of the companion supplementary services named in the support table.
• GSM03.11, GSM04.10, GSM04.80 - cover technical realization, layer 3 supplementary-service aspects, and formats and coding.
• CCITT Recommendation I.210 - provides general principles for describing telecommunication services.

What does the SIST EN 300 918 V7.1.2:2004 document contain?

The document uses a common description format for each supplementary service, covering definition, description, applicability to telecommunication services, normal procedures, exceptional procedures, alternate procedures, interactions with other supplementary services, interworking, dynamic description, and outstanding issues. It also includes Table 3.2 for basic service groups and Table 4.1 for supported supplementary services.

Annex A provides the applicability matrix for telecommunication services, and Annex B gives the change history. Together, these parts let implementers, testers, and operators see both the service behavior and where each service applies.
