Essential patents
IPRs essential or potentially essential to normative deliverables 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 (https://ipr.etsi.org/).
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.
Trademarks
The present document may include trademarks and/or tradenames which are asserted and/or registered by their owners.
ETSI claims no ownership of these except for any which are indicated as being the property of ETSI, and conveys no
right to use or reproduce any trademark and/or tradename. Mention of those trademarks in the present document does
not constitute an endorsement by ETSI of products, services or organizations associated with those trademarks.
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. Full details of the entire series can be found in part 1 [2].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
All the defined quality of service parameters and their computations are based on field measurements. That indicates
that the measurements were made from users point of view (full End-to-end perspective, taking into account the needs
of testing).
It is assumed that the end user 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, need to 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 ETSI TS 102 250-2 [3]
can be measured following the procedures defined in ETSI TS 102 250-3 [4].
Test-equipment fulfilling the specified minimum requirements, will allow performing the proposed measurements in a
reliable and reproducible way.

4 Overview
4.1 General Aspects
All tests are based on emulation of a typical user using services provided in a public mobile network (PMN). All of the
services to be tested (see ETSI TS 102 250-2 [3]) can be emulated by the Mobile QoS Test-equipment (MQT) which
can be installed in a vehicle, can be carried around by a pedestrian or is installed for semi-stationary use (e.g. office
environment).
Test scenarios need to distinguish the following principal user cases.
1) User-to-user services (typically telephony).
