This European Telecommunication Standard (ETS) describes the Configuration Management (CM) aspects of Network Elements (NEs) which constitute a PLMN with initial emphasis on the Base Station System (BSS) management. This is described from a management perspective being decomposed into constituent functionalities, which in turn will allow the construction of a management object model using the object oriented paradigm to support open systems management (see GSM 12.20 (ETS 300 622) [14]). The ETS follows the methodology described in GSM 12.00 (ETS 300 612-1)[10]. This ETS defines a set of controls to be employed to effect set-up and changes to a PLMN, in such a way that operational capability, network integrity and inter working co operation are ensured. In this way, this ETS describes the interface behaviour for the management of PLMN NEs in the context of the described management environment. The context is described for both the Operation System (OS) and NE functionality. The standardisation of specific controls is outside of the scope of this ETS.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS describes the Configuration Management (CM) aspects of Network Elements (NEs) within the
Digital cellular telecommunications system. This ETS corresponds to GSM technical specification, GSM
12.06, version 4.1.1.
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
Configuration Management (CM), in general, provides the operator with the ability to perform effective
network management as the PLMN evolves. CM is initiated by the operator in various network elements of
the PLMN to meet the operator objectives.
CM actions may be requested as part of an implementation programme (e.g. additions and deletions), as
part of an optimisation programme (e.g. modifications), and to maintain the overall Quality of Service. The
CM actions are initiated either as a single action on a network element of the PLMN or as part of a
complex procedure involving actions on many network elements.
Clause 4 provides a brief background of CM while Clause 5 explains CM services available to the
operator. Clause 6 breaks these services down into individual CM functions which will support the defined
services. Clause 7 describes the application of these services and functions to the BSS NE in a GSM
PLMN. In Annex A there are informative examples to illustrate the application of CM functions to complete
scenarios.

1 Scope
This European Telecommunication Standard (ETS) describes the Configuration Management (CM)
aspects of Network Elements (NEs) which constitute a PLMN with initial emphasis on the Base Station
System (BSS) management. This is described from a management perspective being decomposed into
constituent functionalities, which in turn will allow the construction of a management object model using
the object oriented paradigm to support open systems management (see GSM 12.20 (ETS 300 622) [14]).
The ETS follows the methodology described in GSM 12.00 (ETS 300 612-1)[10].
This ETS defines a set of controls to be employed to effect set-up and changes to a PLMN, in such a way
that operational capability, network integrity and inter working co-operation are ensured. In this way, this
ETS describes the interface behaviour for the management of PLMN NEs in the context of the described
management environment. The context is described for both the Operation System (OS) and NE
functionality. The standardisation of specific controls is outside of the scope of this ETS.

4 Network configuration management
4.1 General
In the development of a PLMN, three general phases can be described which represent different degrees
of stability. Once the first stage is over, the system will cycle between the second and the third phases.
This is known as the network life-cycle and includes:
1) the PLMN is installed and put into service;
2) the PLMN reaches certain stability and is only modified (dynamically) to satisfy short term
requirements, e.g. by (dynamic) re-configuration of resources or parameter modification; this stable
state of a PLMN cannot be regarded as the final one because each equipment or SW modification
will let the PLMN progress to an unstable state and require optimisation actions again;
3) the PLMN is being adjusted to meet the long term requirements of the network operator and the
customer, e.g. with regard to performance, capacity and customer satisfaction through the
enhancement of the network or equipment up-grade.
During these phases, the operators will require adequate management functions to perform the necessary
tasks.
4.1.1 Installing a PLMN
When a PLMN is installed and initialised for the first time, all NEs need to be introduced to the OS, the
data for initialisation and SW for proper functioning need to be provided. All these actions are carried out
to create NEs and to initialise them.
4.1.2 Operating a PLMN
Whilst in service, the operator needs to react to short term incidents such as traffic load requirements
which are different from the current network capabilities, NEs/NRs need to be re-configured and
parameters need to be adapted to follow these day-to-day requirements.
4.1.3 Growing/pruning a PLMN
As the PLMN grows and matures new equipment is installed and understanding of system behaviour
increases. Subscriber requirements/wishes may demand that operators modify their system. In addition
manufacturers improve the infrastructure components and add features to their products hence the
operator will start modifying the PLMN to profit from these changes and to improve subscriber satisfaction.
Additionally, the PLMN configuration will be modified (i.e. it will be up-dated or up-graded) to cope with a
need for increasing or decreasing network capacity. These actions are carried out for the long term
strategy of the operators to optimise the network.
4.1.3.1 System up-date
Whenever the PLMN needs to be improved for reasons of reducing failures, the system will be up-dated.
In this case SW or equipment will be replaced without adding new functionalities or resources to the
network. The basic function required is:
the modification of existing SW/equipment; it may be necessary to introduce a different set of data
to cope with the modified SW/equipment.
For system up-date the network shall not be disturbed in its function until the required modification is
activated. This requires mechanisms to
− do SW/data downloading in parallel with on-going traffic;
− isolate the affected NEs/NRs from traffic before the actual modification is done.

SIST ETS 300 617 E1:2003
Page 11
ETS 300 617: June 1996 (GSM 12.06 version 4.1.1)
4.1.3.2 System up-grade
System up-grade may affect all areas of PLMN activities and can be described as enhancements,
whereby either new features or new facilities are implemented. Also extensions, reductions or further
replications of existing facilities are covered by this CM aspect. The CM functions employed are:
− Creation of NEs and/or NRs;
− Deletion of NEs and/or NRs; and,
− Modification of NEs and/or NRs.
The following requirements are to apply:
− to support expeditious handling of SW and data while minimising impact on ongoing traffic;
− to follow a required sequence of up-grades: e.g. the new SW depends upon the availability of the
new equipment functionality;
− to provide the capability to create an additional logical NE/NR without having installed the physical
resource supporting it: for example it should be possible to create a cell in a BSS without the
physical equipment present or connected. However, additional mechanisms should be in place to
prevent any service connection to any physically non-existent NE/NR or reporting failures from non-
existing NE/NR;
− to provide the capability to prevent the erroneous taking into service of a NE/NR which is not fully
installed and initialised: whenever a NE/NR is modified (extension or reduction) it shall be taken out
of service until the logical part of the procedure is finished. An extended NE/NR cannot be placed
into service until all needed parameters and equipment are initialised. Likewise, a reduced NE/NR
cannot be placed back into service until the applicable re-configuration is performed.
When the network is up-graded by the addition of NEs or NRs or a change in the configuration, it is
essential that the NE/NR can be restored to the configuration which existed before the changes were
made. This procedure is called "reversion" and is useful in maintaining service if any difficulty should arise
from a network up-grade.
4.2 Operational context for configuration management
The CM functions available to the operator need to address various aspects beyond that which might
strictly be regarded as management of the network. These include:
− assisting the operator in making the most timely and accurate changes thus avoiding lengthy
waiting periods or complex scenarios;
− ensuring that CM actions will not have any secondary effects on the network other than the
specified ones;
− providing mechanisms to protect the telephony-related traffic from effects due to CM actions, it shall
be possible to inhibit traffic if a traffic affecting CM action is expected and to gracefully release calls
prior to the closure of the resource;
− providing mechanisms to overcome data inconsistency problems by logging the modifications for
reversion reasons, or to recover through data update from a second source.
4.2.1 Administrative aspects of configuration management
When managing the network by creating, deleting or modifying NEs/NRs, the operator should ensure that
there is no uncontrolled impact on the network. The network management system therefore needs to
support the following set of management functionalities when addressing various administrative aspects:
− Security;
− Data Validity;
− Data Consistency; and,
− Resource Administration.

ETS 300 617: June 1996 (GSM 12.06 version 4.1.1)
4.2.1.1 Security aspects
It is up to the operator to ensure the network security by employing the appropriate mechanisms for
control of logical and physical access.
4.2.1.2 Data validity
It is also up to the operator to ensure that data used in CM is valid given the particular network
configuration. Thus, the operator is responsible for the data setting in a given context.
4.2.1.3 Data consistency
The NE-OS relationship employs an object model abstraction of the NE's physical and logical resources to
be managed by the OS which is the agreed MIB between NE and OS. The NE local representation of
those physical and logical instantiated resources to be managed, as well as their accurate mapping onto
the agreed object model abstraction, is a pure matter of the NE manufacturer. Thus the consistency
between the actual local representation of physical and logical resources to be managed within an NE,
and the corresponding view of the OS, totally relies on:
−− which information is exchanged between NE and OS; this is mainly a matter for the GSM 12 series,
defining object models for various functional areas and/or of agreements between the network
operator and his manufacturer(s);
−− how such information is exchanged between NE and OS; this is also a matter for other GSM 12
series documents, refer to GSM 12.01 [11];
−− how information is locally represented and treated by an NE and by its associated OS(s); this is left
to the manufacturers of NEs and OSs.
