Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Speech and multimedia
Transmission Quality (STQ).
The present document is part 5 of a multi-part deliverable covering the QoS aspects for popular services in mobile
networks, as identified below:
Part 1: "Assessment of Quality of Service";
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 builds an umbrella document for this multi-part deliverable. It summarizes the basics of Quality of Service,
always seen from the user's perspective. Differences to Quality of Experience (QoE) are also discussed. In extension to
generic definitions, specific definitions for this multi-part deliverable are stated here. Furthermore, it gives guidance to
assure that QoS assessments can be conducted in a meaningful way and proposes an according process.
Part 2 defines QoS parameters and their computation for popular services in mobile networks. The parameter definition
is split into several parts. It contains an abstract definition which gives a generic description of the parameter, an
abstract equation and the corresponding user and technical trigger points.
The harmonized definitions given in part 2 are considered as prerequisites for the comparison of QoS measurements and
measurement results.
Part 3 describes the measurement procedures needed to perform the measurements of QoS parameters in line with the
definitions given in part 2, applying the test profiles defined in part 5.
Part 4 defines the minimum requirements of QoS measurement equipment for mobile 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.
The present document specifies typical measurement profiles which are required to enable benchmarking of different
mobile networks both within and outside national boundaries.
Part 6 describes procedures to be used for statistical calculations in the field of QoS measurement of mobile networks
using probing systems.
Part 7 describes how Quality of Service measurements should be done inside the network without direct access to the
end point terminal.

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; and
• the target subscriber equipment is ready to answer the call.
Further preconditions may apply when reasonable.
The present document describes a set of typical measurement profiles which are precisely defined to allow for
comparability between different measurements, possibly performed by different parties.
It is necessary to have these profiles so that when a specific set of measurements are carried out then users are
comparing "like for like" performance.

1 Scope
The present document specifies test profiles which are required to enable benchmarking of different mobile networks
both within and outside national boundaries. It is necessary to have these profiles so that when a specific set of tests is
carried out then customers are comparing "like for like" performance.
All timeouts (as part of the profiles) given in the present document are examples from proven experience. It should be
noted that most timeouts given in the present document do with respect to failure ratios as defined in [1] have a direct
impact on measurement results. A timeout value might for example directly relate to the stop trigger point in the sense
of the timeout reached event being the point in time where a certain state has not been reached.

4 Measurement profiles
Measurement profiles are required to enable benchmarking of different networks both within and outside national
boundaries. It is necessary to have these profiles so that when a specific set of tests is carried out then customers are
comparing "like for like" performance.
It is recognized that many factors will affect comparability:
• number of sessions;
• sessions duration;
• time between sessions;
• demanded QoS settings for data services;
• protocol settings (like TCP/IP settings for data services or AMR-settings for speech services);
• usage profile during the session;
• fixed network test equipment like test servers for data sessions;
• user profile stored in the HLR or the GR;
• geographic location;
• type of location (indoor, hotspot, city, suburban, rural, train, etc.);
• speed when mobile;
• type of vehicle;
• type of antenna;
• handset type;
• handset hardware and firmware version;
• service being tested and limitations of service;
• network configuration;
• mobile users' population density.
For the points mentioned above where there is no recommendation or requirement in the present document, the settings
experienced by a regular user of the service under test in the network under test shall be used as a guideline.
As far as possible all particular values, e.g. timeout values, are named preserving the name of the respective Quality of
Service parameters as defined in TS 102 250-2 [1].
4.1 Classification of measurement environments
For interpretation and comparability of test results it is important to know in which measurement environment the tests
were performed. The environment classifications described below shall be used. Since the type of the measurement
locations may be interpreted differently, the particular understanding of the location type determining a category shall
be described in the results report.

4.2 Service profiles
This clause describes recommended service profiles used for testing.
4.2.1 Telephony
The service profiles defined for telephony might be applicable for different scenarios, e.g. mobile-to-mobile or
mobile-to-fixed, and the respective results should not be compared directly, if so.
To achieve comparable statistics when performing a benchmark, there should be no fixed pause between calls. Instead,
a fixed call window is defined in which one single call has to be performed. If the call fails or drops, the next call
attempt shall only be made when the next call window arrives.
A minimum pause interval between two call attempts should be applied to prevent network related problems between
connection release and the next establishment (e.g. signalling in the PSD or mobility management).
4.2.1.1 Speech Telephony
The following call durations shall be used:
• CD1: 10 seconds for call setup testing;
• CD2: 120 seconds for typical tests, default call duration for PLMN;
• CD3: 300 seconds for stability tests;
• CD4: 60 seconds for typical tests, default call duration for TETRA individual calls.
Call Window: Call duration + 30 seconds, (for the setup and release phases) + 30 seconds (for the minimum pause
interval), for the default call duration CD2 this results in 180 seconds call window.
Timeout values:
• Telephony {Service Non-Accessibility | Setup Time} Timeout: 20 seconds.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TS 102 250-5 V2.4.1 (2013-06)
4.2.1.2 Video Telephony
Video Telephony should be tested in mobile-to-mobile scenarios. The following call durations shall be used:
• CD1: 10 seconds for call setup testing;
• CD2: 120 seconds for typical tests, default call duration;
• CD3: 300 seconds for stability tests.
Call Window: Call duration + 30 seconds (for the setup and release phases) + 30 seconds (for minimum pause
interval), for the default call duration CD2 this results in 180 seconds call window.
Timeout values:
• VT Service {Non-Accessibility | Access Time} Timeout: 20 seconds;
• VT Audio/Video Setup {Failure Ratio | Time} Timeout: 30 seconds.
4.2.1.3 Group Call
Group Calls should be tested in mobile-to-mobile(s) scenarios. The following call durations shall be used:
• CD1: 20 seconds for typical tests, default call duration;
• CD2: 60 seconds for stability tests.
Call Window: Call duration + 20 seconds (for the setup and release phases), + 20 seconds (for minimum pause
interval), for the default call duration CD1 this results in 60 seconds call window.
Timeout values:
• Group Call Service Non-Accessibility Timeout: 5 seconds.
4.2.2 Messaging Services
For all messaging services it is important that the recipient of a message is not interrupted by the next message while
retrieving the previous one. For this reason it is important that the interval between sending two messages is larger than
the 95 % percentile of the end-to-end duration, unless measures are taken to avoid this kind of interference.
It should be noted, that mobility of either the sender of a message or the receiver of a message or both of a message can
have an impact on the results. Therefore it is recommended that measurements are not only performed stationary, but
also with mobility of one or both participants. In all cases the used scenario has to be stated.
4.2.2.1 {SMS | SDS}
{SMS | SDS} should be tested in mobile-to-mobile scenarios and without concatenation. Thus the user data should be
chosen in a way that it will fit into a single message.
The interval between two consecutive {SMS | SDS} shall be 60 seconds.
The transmission window of measurements shall be 175 seconds.
Timeout-values:
• {SMS | SDS} Service Non-Accessibility Timeout: 20 seconds;
• {SMS | SDS} Completion Failure Ratio Timeout: 30 seconds;
• {SMS | SDS} Receive Confirmation Failure Ratio Timeout: 60 seconds;
ETSI

---------------------- Page: 10 ----------------------
11 ETSI TS 102 250-5 V2.4.1 (2013-06)
• {SMS | SDS} Consumed Confirmation Failure Ratio Timeout: 60 seconds.
NOTE: It is assumed that in automated measurement systems the consumed confirmation (if enabled) will be
generated immediately after the reception and therefore, the same timeout values for receive and
consumed confirmation apply.
4.2.2.2 Concatenated {SMS | SDS}
For further study.
4.2.2.3 MMS
MMS should be tested end-to-end. That means a MMS sent by A-Party should be received by B-Party using also a
mobile phone. The advantage of this testing is, that the MO direction at A-Party and the MT direction at B-Party can be
measured. Both directions together are the end-to-end parameters described in TS 102 250-2 [1].
The following MMS sizes shall be used:
• MMS1: 2 kByte;
• MMS2: 28 kByte;
• MMS3: 90 kByte.
If the MMS is not delivered at the destination after the MMS end-to-end Failure Ratio Timeout, the MMS delivery is
considered failed. MMS delivered after this time is not taken into account for end-to-end delay, but into end-to-end
failure ratio.
Timeouts for MMS over GPRS:
The timeouts for MMS Send, Retrieval and end-to-end Failure are dependent on the MMS size. For GPRS all MMS
uploads with less than 5 kbits and all MMS downloads with less than 10 kbits are considered to be cut-off.
MMS Send Failure Ratio (MO) Timeout:  (195 + Size[kByte] × 8 × 2/10) [seconds].
MMS Retrieval Failure Ratio (MT) Timeout: (195 + Size[kByte] × 8 × 1/10) [seconds].
The fixed part of 195 seconds incorporate the time for PDP context activation and WAP activation and shall be used as
a whole, i.e. the single timeouts for PDP context and WAP activation shall not be considered.
MMS end-to-end Delivery Failure Ratio Timeout: (590 + Size[kByte] × 8 × 2/10 + Size[kByte] × 8 × 1/10) [seconds].
The fixed part of 590 seconds incorporate the time for PDP context activations, WAP activations and notification and a
security margin. It shall be regarded as a whole, i.e. the single timeouts shall not be considered.
MMS Notification Failure Ratio Timeout: 120 seconds.
Timeouts for MMS over UMTS:
• The timeouts for MMS Send, Retrieval and End-to-end Failure are dependent on the MMS size.
• The respective required minimum upload and download data rate is for further study.
• MMS Send Failure Ratio (MO) Timeout: for further study.
• MMS Retrieval Failure Ratio (MT) Timeout: for further study.
• MMS end-to-end Delivery Failure Ratio Timeout: for further study.
• MMS Notification Failure Ratio Timeout: 120 seconds.

4.2.3 Data services
4.2.3.1 Circuit switched
Circuit switched data services shall be tested for 100 % MOC. Call duration shall be either 300 seconds or is defined by
the usage profile used during the data session. The pause interval between call attempts shall be 30 seconds. The usage
profile used during the data session is defined in clause 4.3.
4.2.3.2 Packet switched
Packet switched data services shall be tested for 100 % MOC sessions. Session duration shall be either 300 seconds or
is defined by the usage profile used during the data session. The pause interval between session setup attempts shall be
30 seconds. The usage profile used during the data session is defined in clause 4.3.
NOTE: In order to ensure comparable results in benchmark testing (on changing access technologies) the number
of measurements per time on the compared channels should be equal (by using test windows or regular
intermediate results) or the individual measurements should be appropriately weighted in the aggregation.
4.2.3.2.1 Service-independent timeout values
• Attach Timeout: 75 seconds.
It might occur that the user equipment sends more than one attach request towards the SGSN, since retries are
necessary. A maximum of four retries are possible (timer T3310 expires after 15 seconds for each attempt, see
TS 124 008 [2].
• PDP Context Activation Timeout for GSM and 3G networks: 150 seconds.
It might occur that the user equipment sends more than one PDP context activation request towards the SGSN, since
retries are necessary. A maximum of four retries are possible (timer T3380 expires after 30 seconds for each attempt,
see TS 124 008 [2]).
• PDP Context Activation Timeout for TETRA networks: 120 seconds.
The timer PDP_WAIT_TIMER expires after 30 seconds for each attempt, see EN 300 392-2 [4]. Note that the number
of retries "RETRY_ACTIVATION = 3" is fixed in the TETRA standard. Therefore the timeout interval for the PDP
context activation procedure is 120 seconds, i.e. if the PDP context activation procedure was not completed after
120 seconds it is considered as failure.
4.2.3.2.2 Service-dependent timeout values
Timeout values for an FTP (ULandDL) service are:
• Service Accessibility Timeout: 150 seconds + IP-Service Access Timeout.
• Setup Time Timeout:  150 seconds + IP-Service Access Timeout.
• IP-Service Access Timeout: 30 seconds.
• Data Transfer Cut-off Timeout:
