Overview

SIST ETS 300 905 E3:2003 defines the recommended set of teleservices to be supported by a GSM Public Land Mobile Network (PLMN), as specified for the Digital Cellular Telecommunications System (GSM Phase 2+). This standard, harmonized with ETSI's GSM 02.03 version 5.3.2, establishes the functional requirements and capabilities that a GSM PLMN must offer for telecommunication services, particularly when connecting with other networks. The document also sets guidelines to prevent the unilateral introduction of new teleservices by operators if such services would require modifications to GSM signaling specifications.

Key Topics

Teleservices Defined by GSM PLMN

• Speech Services: Support for basic telephony and emergency calls, ensuring reliable voice communications consistent with public networks like PSTN and ISDN.
• Short Message Services (SMS): Details the support for mobile-terminated and mobile-originated point-to-point SMS, as well as cell broadcast messaging, enabling text transmission and broadcast to users within defined cell areas.
• Facsimile Services: Specification for alternate speech/facsimile and automatic Group 3 fax (G3), allowing fax transmission between mobile stations and fixed networks via the GSM PLMN.
• Voice Group Call and Broadcast Services: Provision for group communication, such as voice group call service and voice broadcast service, targeting predefined groups in multipoint setups.
• Service Attributes: Classification of teleservices based on high-layer and low-layer (bearer capability) attributes, as well as supplementary attributes like quality of service and commercial features.

Applications

Practical Value in the Telecommunications Industry

• Mobile Network Design and Interconnection
  By defining the standard set of teleservices, this specification ensures interoperability between GSM networks and seamless integration with other public networks (PSTN, ISDN). Network providers can benchmark against these service requirements to design compliant and future-proof infrastructures.

• Operator Service Offerings
  The standard acts as a reference for allowable GSM teleservices, ensuring consistency in essential offerings such as voice, emergency communication, and SMS. It also protects network integrity by preventing proprietary or incompatible service deployment that could impact network functions or interoperability.

• Regulatory Compliance and Quality Assurance
  Compliance with SIST ETS 300 905 E3:2003 is often a legal or regulatory requirement for GSM network operators in many regions. Operators and equipment suppliers rely on these specifications to maintain service quality, ensure user safety (especially for emergency calls), and facilitate cross-network messaging services.

• Roaming and International Compatibility
  The standardized teleservices make international roaming feasible, as users expect consistent and predictable service support-such as SMS and emergency calling-when traveling across networks worldwide.

1 Framework for describing teleservices supported by a GSM PLMN
Teleservices supported by a GSM PLMN are described by a number of attributes which are intended to be
largely independent.
These attributes are described and defined in specification GSM 02.01 [2].
They are grouped into three categories:
- High layer attributes;
- Low layer attributes (describing the Bearer capabilities which support the Teleservice).
- information transfer attributes;
- access attributes.
- General attributes.
NOTE: Teleservices generally make use of underlying lower layer capabilities of Bearer
Services as defined in specification GSM 02.02 [3]. However, where Teleservices are
provided by a single Administration, RPOA or other services provider, the combination
of values of lower layer attributes applicable to specific Teleservices may not
necessarily be identical to any of those identified for the Bearer Services appearing in
specification GSM 02.02 [3].
Figure 1 shows the relationship between the different categories of services attributes, and their scope
within a Teleservice.

4 Description of individual teleservices
The annex contains a data sheet per Teleservice with all attributes and comments.
5 Bearer capabilities supporting teleservices
According to specification GSM 02.01 [2] the Bearer Capability defines the technical features of a
Teleservice as they appear to the user at the customer access point or an appropriate interface of a fixed
network. The Bearer Capability is characterized by information transfer, access and interworking
attributes. The same set of attributes as for a Bearer Service is used. A Bearer Capability is associated
with every Teleservice.

6 Possible further evolution phases of teleservices in a GSM PLMN
Possible further evolution phases according to the definition in GSM 01.06 could become necessary. For
instance, speech coding procedures (half rate speech codec) will provide for the reduction of the bit rate
for speech transmission and thus increase the network capacity.

NOTE 1: Interworking with Telex may be provided via teletex-telex- or other interworking
functions.
NOTE 2: Within the GSM PLMN the "Information transfer rate" attribute is not indicated, this is
because the user may access the PLMN at either an "S" or "R" reference point. In
addition, the "Information transfer rate" at other reference points within the PLMN
assumed or otherwise may be different.

Comments:
This service provides the transmission of speech information and audible signalling tones of the
PSTN/ISDN. In the GSM PLMN and the fixed network processing technique appropriate for speech
such as analogue transmission, echo cancellation and low bit rate voice encoding may be used.
Hence, bit integrity is not assured.
1) Transparency for telephone signalling tones is provided.
2) Transparency for voice band facsimile signals is not mandatory. (Appropriate bearer services see
GSM 02.02 [3].)
3) Transparency for end to end speech encryption is not mandatory. If a user needs to apply this
technique an appropriate bearer service (GSM 02.02 [3]) can be used.
4) Transmission of DTMF is provided in the mobile to fixed direction (e.g. for controlling voice mail
boxes) during any time of an established call.

Comments:
1) A standardized access method throughout all GSM PLMNs is mandatory. In addition national
emergency call numbers of PSTN/ISDN must be usable from MS.
2) It shall be an option of the network operator whether to accept emergency calls coming from mobile
stations which do not transmit an IMSI or a TMSI.
3) Emergency calls supersede all constraints imposed by supplementary services or mobile station
features used for other Tele or Bearer services. The lock state of the MS is overridden by the
SOS-procedure.
4) Emergency calls will be routed to the emergency services in accordance with national regulations.
5) In order to help identifying callers in cases of misuse databases in the GSM PLMN may be
accessed to retrieve the identity of the calling MS.
