Foreword
This European Telecommunication Standard (ETS) was produced by the Special Mobile Group (SMG)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS provides a survey of the GSM network management interfaces and describes the relevant
protocol profiles for Q3 and Qx interfaces within the Digital cellular telecommunications system. This ETS
corresponds to GSM technical specification, GSM 12.01, version 4.4.1 and is part 2 of a 2 part ETS as
described below:
GSM 12.00 ETS 300 612-1: "Digital cellular telecommunication system (Phase 2); Network
Management (NM); Part 1: Objectives and structure of Network Management".
GSM 12.01 ETS 300 612-2: "Digital cellular telecommunication system (Phase 2);
Network Management (NM); Part 2: Common aspects of GSM Network
Management".
NOTE: TC-SMG has produced documents which give technical specifications for the
implementation of the Digital cellular telecommunications system. Historically, these
documents have been identified as GSM Technical Specifications (GSM-TSs). These
specifications may subsequently become I-ETSs (Phase 1), or European
Telecommunication Standards (ETSs)(Phase 2), whilst others may become ETSI
Technical Reports (ETRs). These ETSI-GSM Technical Specifications are, for editorial
reasons, still referred to in this ETS.

1 Scope
This European Telecommunication Standard (ETS) provides the survey of the GSM Network
Management (NM) interfaces in accordance with the requirements in the GSM standards and with the
architectural concept and methodology defined in GSM 12.00 (ETS 300 612-1) [80].
NOTE: The requirements for GSM covers the requirements for a DCS 1800 network as well.
The various possibilities for transfer of NM messages between the NM entities and Network Elements
(NEs) are outlined in this standard, and the requirements are set up for an OSI protocol stack appropriate
for a GSM TMN.
This ETS describes the relevant protocol profiles for Q3 and Qx interfaces.
