SIST ETS 300 504 E4:2003

SIST ETS 300 504 E4:2003 is a SIST adoption of ETS 300 504 from ETSI for GSM Phase 2 digital cellular telecommunications. It describes typical attributes of different types of Mobile Stations (MS) for use on GSM PLMNs, so manufacturers, customers, and approval teams can select or assess MS configurations for GSM and DCS 1800 networks.

What does SIST ETS 300 504 E4:2003 specify?

SIST ETS 300 504 E4:2003 specifies typical Mobile Station attributes for GSM PLMNs, including GSM, DCS 1800, and other PLMNs based on the GSM specification. The document is about configuration and capability, not a complete catalogue of every possible MS type.

The standard is organized into these main parts:

In practice, this means the standard helps a reader understand which combinations of attributes are recognized for MS use on GSM and DCS 1800 networks, while leaving actual product design choices to the manufacturer and customer.

What are the key requirements of SIST ETS 300 504 E4:2003?

SIST ETS 300 504 E4:2003 defines the MS in terms of service access, access capability, and modes of use. These are the main characteristics a buyer or designer should check when deciding whether a terminal fits a target network and service mix.

Service access configuration

Clause 3.1 says the service access configuration must match the customer’s needs and the combination of tele, bearer, and supplementary services to be used. It may be a single unit or a mobile termination with additional Terminal Equipment and/or Terminal Adaptors. In practice, this affects how a terminal is packaged and what external equipment it needs.

Access capability and frequency bands

Clause 3.2 links MS access capability to GSM 04.03 and describes limits on simultaneous tele or bearer services. Clause 3.2.1 defines three bands: Standard GSM Band, Extended GSM Band, and DCS 1800 Band. A multi-band MS must support handover, channel assignment, cell selection, cell reselection, and PLMN selection across its bands, and it must meet the requirements for each band it supports. This matters when a product is meant to roam across bands in one PLMN.

Single-band and dual-band behavior

Clause 3.2.1 also describes a GSM and DCS 1800 capable MS that selects only one band by internal manual or automatic procedure. That MS cannot use both bands at the same time and does not support inter-band handover or reselection. For the reader, this is the distinction between a true multi-band terminal and a terminal that can operate in more than one band but only one at a time.

Full Rate and Half Rate services

Clause 3.2.2 allows Full Rate and Half Rate service support at several levels: Full Rate only, Full Rate plus Half Rate, or no support. MSs that support signalling modes only are also permitted. This helps with service planning because network and device capability do not have to match every speech mode.

Speech codecs

Clause 3.2.3 limits speech teleservice configurations to the Full Rate speech codec only, or Full Rate plus any combination of Enhanced Full Rate and Half Rate. That is the key product-selection point for voice performance and feature sets.

Form factors and power classes

Clauses 3.3 and 3.4 define hand-held MS and vehicular mounted MS by antenna placement. Clause 4 assigns GSM and DCS MS to output power classes and states that the MS must be able to reduce transmitter output power on command from a base station. Clause 5 adds configuration rules, including that a GSM hand-held MS shall only be GSM class 4 or 5, a DCS hand-held MS shall only be DCS class 1 or 2, and a DCS class 3 MS shall only be vehicular mounted.

What terms does SIST ETS 300 504 E4:2003 define?

• Mobile Station (MS) - Equipment used to access GSM PLMN telecommunications services, which may include mobile termination, Terminal Equipment, and Terminal Adaptors.
• GSM PLMN - A GSM, DCS 1800, or other PLMN based on the GSM specification, regardless of frequency band.
• Multi-band Mobile Station - An MS that supports more than one band and can move between them with the required network functions.
• Hand-held MS - An MS where the antenna is directly attached to the speech equipment portion.
• Vehicular mounted MS - An MS where the antenna is mounted outside a vehicle.
• Full Rate - A speech service mode used by the document when describing supported codec and service combinations.
• Half Rate - A speech service mode used alongside Full Rate in the allowed configurations.

Who uses SIST ETS 300 504 E4:2003?

SIST ETS 300 504 E4:2003 is used by GSM and DCS 1800 manufacturers, customers, and approval teams. Manufacturers use it to shape product variants, band support, and power class choices. Buyers and operators use it to compare MS capability against network and service needs. Test and conformity teams use it alongside GSM 11.10 when checking Mobile Station approval.

What changed in SIST ETS 300 504 E4:2003 from the previous edition?

Annex A records the change history and notes a change to the allowed speech codec configuration in the MS. The document history identifies this as the fourth edition.

Which standards are used with SIST ETS 300 504 E4:2003?

SIST ETS 300 504 E4:2003 relies on these standards and companion documents:

• GSM 01.04 - Provides the abbreviations and acronyms used in the document.
• GSM 04.03 - Defines channel structures and access capability for MS-BSS interface behavior.
• GSM 04.08 - Provides the layer 3 specification and the Mobile Station Class Mark reference.
• GSM 05.05 - Defines radio transmission and reception, including output power classes and power reduction.
• GSM 11.10 - Provides the Mobile Station conformity specification and is the reference for type approval.

What does the SIST ETS 300 504 E4:2003 document contain?

The document contains definitions, capability categories, and configuration rules for GSM Mobile Stations. It includes the band list, the service and codec combinations, the hand-held and vehicular mounted definitions, and the power class table for GSM and DCS 1800.

It also gives the practical distinctions between multi-band support and single-band operation, which is useful for design decisions and product declarations. Clause 4 provides the power classification framework that matters for radio design and network command response. Annex A provides a short change history for the edition.
