1 Scope
The present document specifies for User Equipment (UE), in UMTS system, for FDD and TDD modes, those UE
functions that are required for conformance testing purposes.
For conformance tests, functions are activated via the radio interface. These functions shall be capable of being
activated when a test USIM is present. Any USIM related features such as subsidy-related UE features should also not
interfere with the functions. In the loopback state, the UE shall be able to perform all functions specified in the present
document except where otherwise stated; in addition however, the conformance testing functions must be operational.
USIM, in general, is described in TS 31.101 [7]. The ME recognises the test USIM by the Administrative Data Field.
Test USIM data fields are described in TS 34.108 [10].
The present document applies to the unit that includes the hardware to establish a connection across the radio interface.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
UE (User Equipment): user equipment that is under test.
SS (System Simulator): test system (or equipment) that drives the test process between UE, like BS (Base Station)
simulator.
User: test user, who handles the test and measurement process via the logical test interface.
Logical Test Interface: interface which provides the logical service to interwork and to communicate between UE and
System Simulator during the test of a UE.
TC (Test Control): UE protocol entity used by the SS to control the UE specific testing functions.
3.2 Abbreviations
Abbreviations used in the present document are listed in TR 21.905 [6].
For the purposes of the present document, the following abbreviations apply:
IP Internet Protocol
LB Loop Back
RAB Radio Access Bearer
RB Radio Bearer
SAPI Service Access Point Indicator
SS System Simulator
TC Test Control
TFT Traffic Flow Template
UICC UMTS Integrated Circuit Card
UL TFT Uplink Traffic Flow Template
4 UE conformance test functions
4.1 General description
The SS performs activation and deactivation of the conformance test functions in the UE by sending standard NAS
Layer 3 messages. A specific protocol discriminator value has been defined in TS 24.007 [1], subclause 11.2.3.1.1 for
the UE test command messages. Figure 4.1.1 illustrates the Layer 3 protocol entity Test Control (TC) where the UE test
command messages terminates.
NOTE: The protocol discriminator value used for the TC messages is the same as used in GSM for the MS
specific testing functions, see TS 44.014 [13].

Figure 4.1.1: TC protocol termination (TC =Test Control)
Apart from sending the appropriate deactivation command to the UE the functions shall be deactivated by switching off
the UE.
The following UE conformance testing functions can be activated (and deactivated):
- UE test loop function;
- UE radio bearer test mode;
- Electrical Man Machine Interface (EMMI).
In addition to the conformance testing functions listed above there is a set of reference measurement channels that a UE
need to support to enable RF conformance testing. The reference measurement channels are defined in TS 34.121 [8],
Annex C for FDD and in TS 34.122 [9], Annex C for TDD.
Example of reference measurement channels (RMC) essential to all UEs supporting FDD or TDD are:
- UL 12.2 kbps RMC (Reference Measurement Channel);
- DL 12.2 kbps RMC.
Example of reference measurement channels associated with UE service capabilities for FDD (DL and UL) and TDD
(DL only) are:
- DL 64 kbps RMC;
- DL 144 kbps RMC;
- DL 384 kbps RMC;
- UL 64 kbps RMC;
- UL 144 kbps RMC;
- UL 384 kbps RMC.
4.2 UE radio bearer test mode
The UE radio bearer test mode is specified in subclause 5.2.
The following TC procedures are used to control the UE radio bearer test mode:
- Activate UE radio bearer test mode;
- Deactivate UE radio bearer test mode.
4.3 UE test loop
The UE test loop function is specified in subclause 5.3.
ETSI
---------------------- Page: 9 ----------------------
3GPP TS 34.109 version 15.0.0 Release 15 9 ETSI TS 134 109 V15.0.0 (2018-07)
The following TC procedures are used to control the UE test loop function:
- Close UE test loop;
- Open UE test loop.
A prerequisite for the UE test loop function is that the UE radio bearer test mode is active.
4.4 EMMI
The EMMI is specified in clause 7.
No specific TC procedures are associated with EMMI.
5 Test Control (TC) protocol procedures and test loop
operation
5.1 General description
The UE test loop function provides access to isolated functions of the UE via the radio interface without introducing
new physical interfaces just for the reason of conformance testing.
NOTE: It should be emphasised that the UE test loop function only describes the functional behaviour of the UE
with respect to its external interfaces; physical implementation of the UE test loop function is completely
left open to the manufacturer.
The UE test loop function is activated b
