SIST ETS 300 623 E1:2003

Digital cellular telecommunications system (Phase 2) (GSM); Network Management (NM) procedures and messages on the A-bis interface (GSM 12.21)

This European Telecommunication Standard (ETS) addresses the network management messages and procedures across the A-bis interface, which is defined as Qx in GSM. The information model included here defines the objects and how they are addressed for purposes of operations and maintenance activities. There is a requirement for the A-bis interface to be open to allow interoperation between BTSs of different manufacturers working to the same BSC. This ETS addresses this requirement from O&M point of view, which allows this interworking to take place. It shows the split of NM functions between BSC and BTS. The procedures and coding of the messages are specified in detail. In practice, in addition to this ETS it is necessary that the content of manufacturer-dependent information fields be specified to fulfill the functionality. It is essential for operation that a BSC can handle the functions used by all its BTSs. Therefore, all items in this ETS are considered mandatory unless otherwise indicated in 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 network management messages and procedures across the A-bis interface within
the Digital cellular telecommunications system. This ETS corresponds to GSM technical specification,
GSM 12.21, version 4.5.4.
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.
Transposition dates
Date of adoption of this ETS: 06 June 1996
Date of latest announcement of this ETS (doa): 26 September 1996
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 27 March 1997
Date of withdrawal of any conflicting National Standard (dow): 27 March 1997
Introduction
(Background)
The use and general aspects of the A-bis interface are given in specification GSM 08.51. The split of
telecommunications functions and management procedures between BSC and BTS are defined in
specification GSM 08.52. Specification GSM 08.56 defines Layer 2 of the signalling messages.
The general aspects of NM are defined in specification GSM 12.00. Qx interface and protocol stack are
defined in specification GSM 12.01. GSM 12.06 provides the functional requirements supported by this
ETS. The NM procedures and messages to support these operations over the A-bis interface are
specified here. Specification GSM 12.20 provides the information model as seen on the OMC-BSC
interface. Interworking between this model and the NM messages and procedures provided here is
specified in GSM 12.22.

1. Scope
This European Telecommunication Standard (ETS) addresses the network management messages and
procedures across the A-bis interface, which is defined as Qx in GSM. The information model included
here defines the objects and how they are addressed for purposes of operations and maintenance
activities.
There is a requirement for the A-bis interface to be open to allow interoperation between BTSs of different
manufacturers working to the same BSC. This ETS addresses this requirement from O&M point of view,
which allows this interworking to take place. It shows the split of NM functions between BSC and BTS. The
procedures and coding of the messages are specified in detail. In practice, in addition to this ETS it is
necessary that the content of manufacturer-dependent information fields be specified to fulfill the
functionality.
It is essential for operation that a BSC can handle the functions used by all its BTSs. Therefore, all items in
this ETS are considered mandatory unless otherwise indicated in this ETS.
2. Normative References
This ETS incorporates by dated or undated reference, provisions from other publications. These normative
references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references subsequent amendments to, or revisions of, any of these publications apply to this ETS
only when incorporated in it by amendment or revision. For undated references the latest edition of the
