Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Speech and multimedia
Transmission Quality (STQ).
NOTE: Version 2.1.1 of the present document was published with a wrong version number. Please note that the
present version 1.4.1 has been re-published to correct this and therefore superceeds the previous versions
V1.1.1, V1.2.1 and 2.1.1 which have been withdrawn to avoid confusion.
The present document is part 3 of a multi-part deliverable covering the QoS aspects for popular services in GSM and
3G networks, as identified below:
Part 1: "Identification of Quality of Service aspects";
Part 2: "Definition of Quality of Service parameters and their computation";
Part 3: "Typical procedures for Quality of Service measurement equipment";
Part 4: "Requirements for Quality of Service measurement equipment";
Part 5: "Definition of typical measurement profiles";
Part 6: "Post processing and statistical methods";
Part 7: "Network Based Quality of Service Measurements".
Part 1 identifies QoS aspects for popular services in GSM and 3G networks. For each service chosen QoS indicators are
listed. They are considered to be suitable for the quantitatively characterization of the dominant technical QoS aspects
as experienced from the end-customer perspective.
Part 2 defines QoS parameters and their computation for popular services in GSM and 3G networks. The technical QoS
indicators, listed in part 1, are the basis for the parameter set chosen. The parameter definition is split into two parts: the
abstract definition and the generic description of the measurement method with the respective trigger points. Only
measurement methods not dependent on any infrastructure provided are described in the present document. The
harmonized definitions given in the present document are considered as the prerequisites for comparison of QoS
measurements and measurement results.
Part 3 describes typical procedures used for QoS measurements over GSM, along with settings and parameters for such
measurements.
Part 4 defines the minimum requirements of QoS measurement equipment for GSM and 3G networks in the way that
the values and trigger-points needed to compute the QoS parameter as defined in part 2 can be measured following the
procedures defined in part 3. Test-equipment fulfilling the specified minimum requirements, will allow to perform the
proposed measurements in a reliable and reproducible way.
Part 5 specifies test profiles which are required to enable benchmarking of different GSM or 3G networks both within
and outside national boundaries. It is necessary to have these profiles so that when a specific set of tests are carried out
then customers are comparing "like for like" performance.

Part 6 describes procedures to be used for statistical calculations in the field of QoS measurement of GSM and 3G
networks using probing systems.
Part 7 describes the methodology to be used to get statistical samples that could be representative of the population of
all existent calls so the statistical inferences made from the data collected by test calls are statistically correct and the
error margin could be calculated.
Introduction
All the defined quality of service parameters and their computations are based on field measurements. That indicates
that the measurements were made from customers point of view (full End-to-end perspective, taking into account the
needs of testing).
It is assumed that the end customer can handle his mobile and the services he wants to use (operability is not evaluated
at this time). For the purpose of measurement it is assumed that:
• the service is available and not barred for any reason;
• routing is defined correctly without errors;
• the target subscriber equipment is ready to answer the call;
• voice quality values measured should only be employed by calls ended successfully for statistical analysis;
• need to define similar for video calls;
• however, measured values from calls ended unsuccessfully (e.g. dropped) should be available for additional
evaluations and therefore, must be stored;
• further preconditions may apply when reasonable.

1 Scope
The present document describes typical procedures used for QoS measurements on mobile communication networks,
e.g. GSM or UMTS, along with settings and parameters for such measurements.
Where possible existing ITU-T or ETSI definition are referenced. In some cases ITU-T or ETSI definitions do not exist
or are considered as too generic, then a more service and mobile network specific definition is chosen.
2 References
References are either specific (identified by date of publication and/or edition number or version number) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
• Non-specific reference may be made only to a complete document or a part thereof and only in the following
cases:
- if it is accepted that it will be possible to use all future changes of the referenced document for the
purposes of the referring document;
- for informative references.
Referenced documents which are not found to be publicly available in the expected location might be found at
http://docbox.etsi.org/Reference.
For online referenced documents, information sufficient to identify and locate the source shall be provided. Preferably,
the primary source of the referenced document should be cited, in order to ensure traceability. Furthermore, the
