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.

Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Speech and multimedia Transmission
Quality (STQ).
Standardization offers a large portfolio of QoS and QoE metrics to describe and assess the quality of services available
through mobile devices. These standards also provide measurement methodologies to produce these QoS and QoE data.
With a few exceptions (e.g. Multi-RAB), these methodologies use scenarios where a service is used exclusively. This is
different from typical user behavior where multiple services are interchanged in the same session, or even run
concurrently. The present document addresses this topic by providing a taxonomy and a descriptive framework which
integrates multiple services and the use of multi-service applications with existing QoS and QoE metrics. It thereby
integrates existing single-service methodologies effortlessly, such that they become a particular case of parametrization
of a multi-service test case.
Modal verbs terminology
In the present document "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
Mobile communication networks and smartphones are enabling a wide range of user-centric services, from text
messaging and telephony to multimedia applications. Usage of such services often takes place in a concurrent way, i.e.
several services are used in parallel, or in close succession.
While standardized quality metrics exist to describe individual services, aspects of concurrent usage are only addressed
in a limited way (see for instance ETSI TS 102 250-2 [i.1], clause 6.12 and ETSI TR 103 114 [i.2]).
The purpose of the present document is to provide a comprehensive framework for testing concurrent use of multiple
services. This framework is designed to be modular and scalable with respect to seamless expansion to new services. It
is not restricted to particular services or multi-service carrier applications, i.e. it covers the whole range of "over the
top" (OTT) applications and services.

1 Scope
The present document provides a framework for concurrent tests of multiple services, using a top-level approach which
is also modular and scalable with respect to new services. Also, the framework explicitly integrates measurement
methodology, in particular reproducibility aspects.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
IP Multimedia Subsystem (IMS): telecommunication system for standardized access to services from different
networks
NOTE: IMS specifications were created and are maintained by 3GPP.
Over The Top (OTT): In the context of services which use standard services of a network but may use also proprietary
protocols.
TM
NOTE: An example would be WhatsApp which uses packet data transfer to implement a group of services
including but not limited to telephony, text messaging and file transfer.

4 Basic considerations
Concurrent or near-concurrent use of multiple services takes place in many user situations. In most cases, this happens
unnoted, such as the download of an app update, e-mail, or some pre-scheduled music or video download during direct
user activities such as telephony or web browsing.
In addition, there are applications that directly support usage of multiple services, e.g. sending or receiving images,
videos or other units of data during a conversation.
Therefore, the performance of a particular service may depend on the activity environment in which it is taking place.
Existing network technologies already use resource optimization strategies, which make their behavior content-
dependent. This context dependency can be expected to f
