This Technical Specification has been produced by the 3 Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
Introduction
(Background)
The use and general aspects of the A-bis interface are given in specification 3GPP TS 48.051. The split of
telecommunications functions and management procedures between BSC and BTS are defined in specification 3GPP
TS 48.052. Specification 3GPP TS 48.056 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 the present document. 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.
ETSI
3GPP TS 52.021 version 13.0.0 Release 13 8 ETSI TS 152 021 V13.0.0 (2016-01)
1 Scope
The present document 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. The present document 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 the present document 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 the present
document are considered mandatory unless otherwise indicated in the present document.

5 Information Model
5.1 Managed Objects
The BCF mentioned in 3GPP TS 48.052 and 3GPP TS 48.056 is the agent at the BTS end of the A-bis O&M interface.
It has four different descriptions depending on the object that is managed: Site Manager, BTS, Radio Carrier and
Baseband Transceiver.
This model describes how objects are managed across A-bis interface, but it doesn't specify how information is
transferred inside the site. That is, the manner of communication between an object and objects under it is not specified
in the present document.
As shown in Figure 1, the Object Class
