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 the conceptual and methodological framework for the definition of a standardized
approach to the management of a PLMN within the Digital cellular telecommunications system. This ETS
corresponds to GSM technical specification, GSM 12.00, version 4.5.1 and is part 1 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.

Introduction
The goals of implementing a Public Land Mobile Network (PLMN) and its continued effective operation,
administration and maintenance are important issues. The creation of a system for the management of a
PLMN, implemented according to the specification series 01 to 11 and the open, multi-vendor
environment, demands a level of standardization of the inter-connectivity of the management components
and their functionality. A system for Operation, Administration and Maintenance (OAM), using concepts of
telecommunications management networks (TMN), potentially provides for a suitable degree of
management integration in achieving these goals.
Page 8
ETS 300 612-1: August 1996 (GSM 12.00 version 4.5.1)
Approach
In order to achieve the above aim, the GSM 12 series of specifications has been devised, taking into
account the following:
- GSM system philosophy, as given by the GSM 01 to 11 series of specifications, which define key
functional areas.
- Relevant standardization work on network management and open systems management (as well
as its realization, Telecommunications Management Network, TMN) already carried out by ISO,
CCITT, ETSI etc.
- Existing operator and manufacturer experience in the management (i.e. operating, maintaining,
administering) of telecommunication networks.
Accordingly, this ETS, and the other specifications of the 12-series, should adhere to the following
guidelines:
- There should be internal consistency of the 12 series with the relevant system aspects given in 01
to 11 series Specifications, so that a commonly agreed view of the realization of a PLMN emerges.
- Avoidance of "re-writing" existing recommendations and specifications, but only referencing those
applicable as far as possible. However, to ensure harmony with any such existing documents, some
general items, such as definitions and figures may be reproduced within the 12 series if they are
deemed important or helpful in establishing a common understanding.
- Analysis of current network management concepts and experience both with a top-down and
bottom-up approach, so that a comprehensive and realistic management concept emerges.

1 Scope
This European Telecommunication Standard (ETS) provides the conceptual and methodological
framework for the definition of a standardized approach to the management of a PLMN. (This framework
is elaborated in the remainder of the 12-series specifications) It introduces concepts developed for the
management of telecommunications networks by other standards groups, discusses their use in the
context of the management of a PLMN, defines a complete context for PLMN management information
and identifies the developments of other management models which can be beneficially employed in the
global and integrated management of a PLMN.
This ETS also describes the methodology to be employed in the definition of the standardization activity
and the scale of the results which are expected to be achieved.
PLMN management is described in terms of the objectives for the Operator enterprise. Relationships exist
between network management functionality and functionality required to support the enterprise model.
While the definition of the enterprise model is outside of the scope of this series of ETSs, an
understanding of the requirements is necessary so as to provide the underlying network management
procedures.
Field of application
The concept of the Telecommunications Management Network (TMN) has developed as the result of a
demand for a common management approach to the management of the diversity of equipment types,
functionality and service provision inherent in modern telecommunications networks. This diversity is also
apparent in a PLMN and the adoption of the TMN concept can provide a common management
methodology for:
- public and private networks (including mobile);
- transmission terminals;
- transmission systems;
- restoration systems;
- operations systems and their peripherals;
- digital and analogue exchanges;
- area networks;
- circuit and packet switched networks;
- signalling terminals and systems;
- bearer services and teleservices;
- software provided by or associated with telecommunications services;
- software applications;
- associated support systems;
- the TMN itself.
(For a comprehensive view of the field of application of the TMN, refer to CCITT Recommendation
M.3010 [1])
By extension, the field of application includes radio base station systems and all other components of the
PLMN.
Page 10
ETS 300 612-1: August 1996 (GSM 12.00 version 4.5.1)
Typically a PLMN is a telecommunications system consisting of several functional units necessary to
perform mobile telecommunications services. These functional units include:
- Location Registers (LR);
- Home Location Register(s) (HLR);
- Visitor Location Register(s) (VLR);
- Mobile-services Switching Centre(s) (MSC);
- Base Station Systems (BSS);
- Mobile Stations (MS);
- Equipment Identity Register (EIR);
- Authentication Centre (AUC);
- Inter-working units;
- Transcoders;
- Transmission equipment;
- Echo Suppression equipment.
NOTE: several of the above mentioned functional units may be collocated or even be
accommodated in the same physical implementation.

2 Objectives of Operations, Administration & Maintenance (OAM) of a PLMN
The OAM of a PLMN will require all aspects of the OAM of existing terrestrial telecommunications with
extensions and enhancements to encompass the particular requirements of mobile telephony.
The management should provide all the capabilities necessary for the integration of all the activities
involved in the operation of a mobile network. These activities can be described in terms of Business and
Service criteria. These functions are distanced from the actual PLMN infrastructure, except for the local
maintenance intervention on a network element. (See figure 2/12.00 for an example functional
architecture.)
The objective of PLMN management is to integrate the spectrum of PLMN Operator activities to achieve
coherent and seamless information exchange, support Quality of Service objectives and assist in
achieving business objectives.
2.1 PLMN requirements for Network Management
The basic requirements for an integrated mobile communications system lead to the following general
objectives for PLMN Management:
- Integrated operation of the elements of a PLMN using standardized functionality;
- Inter-PLMN operation of the mobile system;
- Information on the Quality of Service provided.
2.1.1 Standardized OAM functionality
If Operators wish to make use of the advantages in procurement of a standardized PLMN, there is also a
need for standardization of OAM functions to allow proper inter-working of management for network
elements from different manufacturers.
To restrict neither the Operator nor the manufacturer, the standardization provides a logically structured
framework for the necessary functions with freedom for supplementary additions and room for particular
expansions and future evolution. This can be achieved by a management system, defined by a logical
concept with the goal of true implementation.
The 12-series of Specifications defines a functional architecture with immediate relevance to the
management of a PLMN using a logically structured functional model. Standardization is introduced in
those areas where it is felt to be appropriate (utilizing accepted techniques) with reference to the work of
other TMN and Systems Management standardization groups.
Management functions can be classified in terms of their level of definition, to facilitate the objectives of
GSM. These are described in the following paragraphs.
a) Operational standardization:
Functions included here are those necessary to support inter-PLMN roaming and network inter-
working with other PLMNs or other networks.
b) Multi-vendor environment standardization:
If a PLMN Operator wishes to operate in a multi-vendor environment, management functions and
interfaces should be standardized to allow common modes of operation. This may include
performance data collection, message format standards, security methodologies and consistency of
maintenance approach.
c) PLMN management facilities:
Functional areas within the control of a PLMN Operator are recommended for standardization but
particular Operator requirements will impinge on the extent of the possible definition.
d) Specific PLMN management or national requirements:
These are considered to be outside of the scope of standardization.

It is therefore necessary to determine three immediate levels of optional implementation criteria for the
management functions described and defined in this series of specifications:
Mandatory: the implementation of the function shall accord with the definition to allow successful
working and inter-working of the PLMN;
Standard Option: implementation of the function is optional but, if implemented, the definition contained
in the 12-series shall be employed;
Optional: the feature is described but both the use of the feature and the implementation method
are optional.
2.1.2 Inter-Network operation
Inter-Network operations include:
- operation between PLMNs (of the same type) with Operators in different countries;
- (inter-PLMN) operation between PLMN(s) (of the same type) with Operator(s) in the same country;
- operation (inter-working) with
