IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Speech and multimedia
Transmission Quality (STQ).
The present document is part 4 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 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 performing 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.

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 user equipment 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 not barred for any reason;
• routing is defined correctly without errors; and
• the target subscriber equipment is ready to process the service request.
Speech and video quality values measured should only be applied by calls ended successfully for statistical analysis.
However, measured values from calls ended unsuccessfully (dropped) should be available for additional evaluations and
therefore, must be stored.
Further preconditions may apply when reasonable.

1 Scope
The present document defines the minimum requirements of QoS measurement equipment for digital wireless networks
in the way that the values and trigger-points needed to compute the QoS parameter as defined in TS 102 250-2 [3] can
be measured following the procedures defined in TS 102 250-3 [4].
Test-equipment fulfilling the specified minimum requirements, will allow performing the proposed measurements in a
reliable and reproducible way.
