22.8.4.1 Initial conditions
|
The SS establishes a BCCH and optionally a PBCCH on the same carrier in the mid ARFCN range. GPRS_MS_TXPWR_MAX_CCH is set to the maximum level (36dBm for DCS 1 800 and PCS 1 900 and 39dBm for all other bands). The CH value is set such that (0 - CH) equals the maximum power control level supported by the Power Class of the MS under test. The value is set to 0.
The SS establishes a downlink TBF on the same ARFCN as the BCCH and PBCCH, and send data blocks to poll the MS for channel quality reports. The downlink power level is adjusted until a stable RXLEV-value of 58 is reported by the MS in the channel quality report (see 3GPP TS 05.08, subclause 8.1.4 and 10.2.3) – corresponding to a used C value in the range of -52dBm to -53dBm.
The SS orders the MS to transmit on the uplink. This is achieved using the GPRS test mode by transmitting a GPRS_TEST_MODE_CMD (see 3GPP TS 04.14, clause 5.4).

22.8a EGPRS2A Uplink Power Control - Use of and CH parameters
22.8a.1 Definition
Power control is important for spectrum efficiency as well as for power consumption in a cellular system. Power control for a packet oriented connection is more complicated than for a circuit switched connection, since there is no continuous two-way connection.
Since the conformance requirements, test procedures and test requirements for EGPRS uplink power control – use of and CH are defined in subclause 22.8 only 16QAM specific requirements and procedures are handled with this subclause. The RF output power, PCH , to be employed by the MS on each individual uplink PDCH shall be:
PCH = min(0 - CH - (C + 48), PMAX),
Where:
CH is an MS and channel specific power control parameter, sent to the MS in an RLC control message (see 3GPP TS 44.060).
0 = 36 dBm for DCS 1800 and DCS 1900
= 39 dBm for all other bands.
is a system parameter sent to MS in an RLC control message (see 3GPP TS 44.008 / 3GPP TS 24.008 and 3GPP TS 44.060).
C is the normalised received signal level at the MS as defined in 3GPP TS 45.008, subclause 10.2.3.1.
PMAX is the maximum allowed output power in the cell = GPRS_MS_TXPWR_MAX_CCH
All power values are expressed in dBm. (Note that the constants 0 and 48 are included only for optimising the coding of CH and C-value).
This is a flexible tool that can be used for different power control algorithms.
A pure open loop is achieved by setting = 1 and keeping CH constant. With this method the output power is based on the received signal level assuming the same path loss in uplink and downlink. This is useful in the beginning of a packet transmission.
A pure closed loop is achieved by setting = 0. With this method the output power is commanded by the network based on received signal level measurements made in the BTS in a similar way as for a circuit switched connection.
22.8a.2 Conformance requirement
1. The MS shall use the same output power on all four bursts within one radio block. 3GPP TS 3GPP TS 45.008, subclause 10.2.1.
2. If a calculated output power is not supported by the MS, the MS shall use the supported output power which is closest to the calculated output power. 3GPP TS 45.008, subclause 10.2.1.
3. When the MS receives new CH or values, the MS shall use the new value to update PCH 2 radio blocks after the end of the frame containing the last timeslot of the message block containing the new value. 3GPP TS 45.008, subclause 10.2.1.
4. The transmitted power shall be a monotonic function of the calculated output power and any change of 2 dB in the calculated value shall correspond to a change of 2 1,5 dB in the transmitted value. The MS may round the calculated output power to the nearest nominal output power value. 3GPP TS 45.008, subclause 10.2.1.
22.8a.3 Test purpose
1. To verify the MS uses that the same output power on all four bursts of a radio block under normal conditions.
2. To verify that the highest power supported by the MS is used if the calculated power is greater.
3. To verify that the MS applies new CH or values 2 radio blocks after the end of the frame containing the last timeslot of the message block containing the new value.
4. To verify that any change of 2 dB in the calculated power corresponds to a change of 2 1,5 dB in the transmitted value under normal conditions.
NOTE: For changes in calculated power which are less than the tolerances specified for absolute power accuracy in a MS, the transmitted power as a function of calculated power cannot be tested for monotonicity. Monotonicity between power control steps is implicitly tested in subclause 13.16.

22.9a EGPRS2A Uplink Power Control - Independence of TS Power Control
22.9a.1 Definition
Since the conformance requirements, test procedures and test requirements for EGPRS uplink power control – Independence of TS Power control are defined in subclause 22.9, only 16QAM specific requirements and procedures are handled with this subclause.
22.9a.2 Test conformance
For an EGPRS2A multislot MS supporting 2 or more uplink PDCHs, power control shall be employed by the MS on each individual uplink PDCH. 3GPP TS 05.08, subclause 10.2.1.
On a multislot uplink configuration the MS may restrict the interslot output power control range to a 10 dB window, on a TDMA frame basis. On those timeslots where the ordered power level is more than 10 dB lower than the applied power level of the highest power timeslot, the MS shall transmit at a lowest possible power level within 10 dB range from the highest applied power level, if not transmitting at the actual ordered power level. 3GPP TS 45.005, subclause 4.1.1.
22.9a.3 Test purpose
To verify that EGPRS power control is applied to each PDCH in a multislot configuration independently.
22.9a.4 Test method
22.9a.4.1 Initial conditions
The SS establishes a downlink TBF. The SS orders the MS to transmit on the maximum number of timeslots for the multislot class of the MS on the uplink. This is achieved using the GPRS test mode by transmitting a GPRS_TEST_MODE_CMD (see 3GPP TS 04.14, subclause 5.4).
Each timeslot is transmitting on its maximum power. The -value is set to 0.
Specific PICS Statements:
- MS using reduced interslot dynamic range in multislot configurations
PIXIT Statements:
-
22.9a.4.2 Procedure
a) The SS shall modify the CH value of one timeslot such that (0 - CH) equals the minimum power control level supported by the MS under test (0dBm for DCS 1 800 and PCS 1 900 and 5dBm for all other bands).
b) The SS shall make a transmitter output power measurement on each of the four bursts of any radio block of the timeslot under test.
NOTE: For 16QAM modulation, a measurement method for estimating the long term average power from a single burst shall be employed. See subclause 13.17.3a.
c) The SS shall make a transmitter output power measurement on each of the four bursts of any radio block of the other active timeslots.
d) The SS shall modify the CH value for the timeslot under test such that (0 - CH) equals the maximum power control level supported by the MS under test.
e) Steps a) to d) shall be repeated for each timeslot of the multislot configuration.
22.9a.5 Test requirement
1. The power of all four bursts within the radio block measured in step b) shall be 0dBm for a DCS 1 800 or PCS 1 900 MS and 5dBm for all other MS with an accuracy of 5 dB in all cases. For an MS using reduced interslot dynamic range, the power measured in step b) shall be within 10dB ± 3dB of the average power of the timeslots measured in step c).
2. For all TS, the power of all four bursts within the radio block measured in step c) shall be within the accuracies specified for the power class of the mobile under test, as indicated in table 22.9-1 (see also 3GPP TS 05.05 / 3GPP TS 45.005).

22.11.1 Conformance requirements
|
Sub-clauses 10.2.1 and 10.2.2 do not apply for the PDCH/H in Exclusive MAC mode while in DTM. In this case:
- The MS shall apply the output power ordered by the network on the SACCH to all channels (both for the TCH/H and the PDCH/H).
- The network shall use the same output power on the dedicated connection and on all the blocks on the PDCH/H addressed to the MS. Blocks not addressed to the MS may be transmitted at a lower power level. As an exception, the bursts transmitted on the BCCH carrier shall be transmitted at the BCCH level.
NOTE: Power control is not applicable to point-to-multipoint services.

Initial Conditions
System Simulator:
1 cell, DTM supported.
Mobile Station:
The MS is in the active state (U10) of a call.
The MS is GPRS idle with a P-TMSI allocated and the PDP context 1 activated.
Test Procedure
The MS is triggered to initiate packet uplink transfer data and sends a DTM REQUEST message to the SS. On receiving the DTM REQUEST message, requesting uplink resources, the SS assigns the MS PS resources in a timeslot adjoining the CS resource. The SS accomplishes the resource assignment by passing a PACKET ASSIGNMENT message to the MS. Once the SS has verified that the MS is correctly sending RLC data blocks to the SS, the SS sets TXPWR in the SACCH to the maximum peak power appropriate to the class of the MS. The SS measures the MS transmitter output power, on the timeslot(s), which changes by one power step towards the new level signalled for each measured burst until the MS is operating at the closest supported power control level and from then on, all transmissions shall be at that level. The SS then sets the TXPWR to a lower random value and then verifies that the MS lowers the output power of the transmitter for both the PDTCH and the TCH to this level. After the SS has received approximately 9k octets of data from the MS, the SS commands the change of transit power by passing the PACKET POWER / TIMING ADVANCE message to the MS on the PACCH. Whilst the MS continues with the transmission of the 10k octets, the SS verifies that the MS has not followed the order to change power as indicated in the PACKET POWER / TIMING ADVANCE message.

Initial Conditions
System Simulator:
1 cell, GPRS and EGPRS supported.
The test is performed in TU50 radio environment, at the reference point of c/i = 16dB.
Mobile Station:
The MS is in GPRS idle mode with a P-TMSI allocated and the PDP context 2 activated; it is allocated a GPRS TBF.
Test Procedure
The GPRS MS is allocated a downlink TBF (TBF1) and a downlink EGPRS transfer is simulated as if an EGPRS downlink TBF (TBF2) were allocated on the same PDCHs. Downlink RLC data blocks are sent to MS using the same power level while on TBF2 different power levels are used: on the EGPRS TBF, downlink RLC data blocks are sent at the BCCH (P0 = 0 dB) power level, then RLC data blocks with different attenuations and valid PR fields are sent.
During the transfer, the RLC data blocks shall be correctly received by the GPRS MS (TBF1) under the 05.05 requirements.

22.13.1 Definition
|
The EPC is Rel-5 feature which is part of GERAN Feature Package 2, see 3GPP TS 24.008. The EPC signalling is mapped onto every SACCH burst, allowing a control interval of 120 ms. It can be used with any speech traffic channel (both GMSK and 8PSK modulated) and does not impact the speech channel coding. The EPC is based on differential control to adjust the employed RF power level, see 3GPP TS 45.008.

22.13.2 Test conformance
|
1. The MS shall employ the most recently commanded EPC power control level, as indicated by the EPC Uplink Power Control Command sent on the corresponding EPCCH in the downlink. The EPC Uplink Power Control Command is sent once every EPC reporting period, see 3GPP TS 45.008 subclause 8.4.1b. The MS shall ignore the Ordered MS Power Level sent in the SACCH L1 header in the downlink, 3GPP TS 45.008, subclause 4.2.
2. When on a channel in EPC mode, the MS shall use the EPCCH in the uplink for EPC measurement reporting, 3GPP TS 45.008 subclause 4.2.
3. When on a channel in EPC mode, the MS shall confirm, in the SACCH L1 header on the uplink, the RF power control level at the last burst of the previous SACCH period, as specified for normal power control, 3GPP TS 45.008, subclause 4.2
4. If a power control command is received but the requested output power is not supported by the MS, the MS shall use the supported output power which is closest to the requested output power, 3GPP TS 45.008, subclause 4.3
5. The enhanced power control mechanism shall use the differential power control mechanism defined in 3GPP TS 45.008, subclause 4.3
6. When the MS is ordered to obey the Ordered MS Power Level, the timing according to 3GPP TS 45.008 subclause 4.7.1 applies, see 3GPP TS 45.008, subclause 4.7.3
7. When the MS is ordered to obey the EPC Uplink Power Control Command, it shall, upon receipt of an EPC Uplink Power Control Command on an EPCCH in the downlink, change to the new power level on the corresponding uplink channel at the first TDMA frame belonging to the next EPC reporting period (as specified in 3GPP TS 45.008 subclause 8.4.1b), see 3GPP TS 45.008, subclause 4.7.3

22.13.4.2 Procedure
|
If the MS supports both GMSK and 8PSK modulation on the uplink, the test is repeated with each modulation format.
a) Using the normal power control mechanism, the SS shall command the MS to transmit at power level 8 (14dBm) in the case of DCS 1 800 and PCS 1 900 or power level 15 (13 dBm) in the case of all other bands on the TCH/O-TCH, see 3GPP TS 45.005, clause 4. After 1s, see 3GPP TS45.008, clause 4.71 a power measurement shall be made.
NOTE: The method of measuring the MS transmitter output power is given in subclause 13.3. For 8PSK modulation, a measurement method for estimating the long term average power from a single burst shall be employed. See subclause 13.17.3.
b) The SS shall command the MS to switch from normal power control to EPC by means of the SACCH L1 header (see 3GPP TS 44.004). The SS shall note the MS TX power reported by the MS in the EPC reporting period following the change from normal power control to EPC.
c) The SS shall command the MS to follow the schedule of enhanced power control detailed in table 22.13-1 below. The SS shall make power measurements during frame n of each SACCH period when enhanced power control is active. These power measurements shall be referred to as Pn,m respectively.

22.14.1 Definition
|
The EPC is Rel-5 feature which is part of GERAN Feature Package 2, see 3GPP TS 24.008. The EPC is based on differential control to adjust the employed RF power level, see 3GPP TS 45.008.
High Speed Circuit Switched Data (HSCSD) is one possibility for EPC operation in multislot configuration, see 3GPP TS 45.002, clause 6.4.2.1

22.14.2 Test conformance
|
8. The MS shall employ the most recently commanded EPC power control level, as indicated by the EPC Uplink Power Control Command sent on the corresponding EPCCH in the downlink. The EPC Uplink Power Control Command is sent once every EPC reporting period, see 3GPP TS 45.008 subclause 8.4.1b. The MS shall ignore the Ordered MS Power Level sent in the SACCH L1 header in the downlink, 3GPP TS 45.008, subclause 4.2.
9. In case of a multislot configuration, each bi‑directional channel shall be power controlled individually by the corresponding SACCH, E-IACCH or EPCCH, whichever is applicable, 3GPP TS 45.008, subclause 4.2
10. When on a channel in EPC mode, the MS shall use the EPCCH in the uplink for EPC measurement reporting, 3GPP TS 45.008 subclause 4.2.
11. When on a channel in EPC mode, the MS shall confirm, in the SACCH L1 header on the uplink, the RF power control level at the last burst of the previous SACCH period, as specified for normal power control, 3GPP TS 45.008, subclause 4.2
12. If a power control command is received but the requested output power is not supported by the MS, the MS shall use the supported output power which is closest to the requested output power, 3GPP TS 45.008, subclause 4.3
13. The enhanced power control mechanism shall use the differential power control mechanism defined in 3GPP TS 45.008, subclause 4.3
14. When the MS is ordered to obey the Ordered MS Power Level, the timing according to 3GPP TS 45.008 subclause 4.7.1 applies, see 3GPP TS 45.008, subclause 4.7.3
15. When the MS is ordered to obey the EPC Uplink Power Control Command, it shall, upon receipt of an EPC Uplink Power Control Command on an EPCCH in the downlink, change to the new power level on the corresponding uplink channel at the first TDMA frame belonging to the next EPC reporting period (as specified in 3GPP TS 45.008 subclause 8.4.1b), see 3GPP TS 45.008, subclause 4.7.3

22.14.4.1 Initial conditions
|
A call is set up by the SS according to the generic call set up procedure for multislot configuration on a channel with ARFCN in the Mid ARFCN range (see table 3.3).
The SS commands the MS to operate in multislot configuration where it has the highest possible number of bi‑directional TCHs or O-TCHs. Using normal power control, the level of each TX slot is set to maximum power.

22.14.4.2 Procedure
|
If the MS supports both GMSK and 8PSK modulation on the uplink, the test is repeated with each modulation format.
For the purpose of this test the SS shall randomly select one bi-directional TCH (in case of GMSK modulation) or O-TCH (in case of 8PSK) to exercise. All other channels shall maintain the state defined under the initial conditions. In this procedure these other TCHs/O-TCHs are referred to as the active but unselected channels.
a) Using the normal power control mechanism, the SS shall command the MS to transmit at power level 8 (14dBm) in the case of DCS 1 800 and PCS 1 900 or power level 15 (13 dBm) in the case of all other bands on the selected TCH/O-TCH, see 3GPP TS 45.005, clause 4. After 1s, a power measurement shall be made on each TX slot of the multislot configuration.
NOTE: The method of measuring the MS transmitter output power is given in subclause 13.3. For 8PSK modulation, a measurement method for estimating the long term average power from a single burst shall be employed. See subclause 13.17.3.
b) The SS shall command the MS to switch between the normal power control and the enhanced power control mechanism on the selected TCH/O-TCH by means of the SACCH L1 header (see 3GPP TS 44.004). Each power control mechanism shall be maintained for 6 SACCH multiframes. This cycle shall be repeated until all power measurements specified in steps iii) to vi) below have been completed.
During the SACCH periods when normal power control is active, the SS shall command the MS to maintain the power levels set in step a). During the SACCH periods when Enhanced Power Control is active, the SS shall command the MS to follow the schedule of enhanced power control detailed in table 22.14-1 below.

683b5b8a98f7b1390ddd5516ea9247a2

|
25.1.1 General
|
The objective of clause 25 is to provide detail of how Layer 2 of the MS is tested to verify conformance to the testable parameters given in 3GPP TS 04.06. The tests cover SAPI = 0, and they will be carried out on SDCCH and FACCH/F and on FACCH/H if the MS supports half-rate. Testing of unnumbered information transfer on SACCHs is covered implicitly by the test in subclause 26.6.3.
The testing is performed using the test configuration described in subclause 25.1.1.2. This configuration does not provide for testing of conformance of any maintenance functions.
The MS under test shall conform to the test configuration, and the Remote Single layer (RS) test method (ITU-T Recommendation X.290, subclause 8.1.4) will be used.

683b5b8a98f7b1390ddd5516ea9247a2
|
51.010-1
|
25.1.2 Test configurations
|
The Layer 2 test configuration defines the Layer 2 functional blocks of a MS being tested and the access arrangement between MS and tester.
NOTE: These functional blocks provide the Layer 2 basic capabilities which have to be implemented in accordance with the specification given in 3GPP TS 04.06. However, the definition of Layer 2 in the form of a number of functional blocks places no requirements on the Layer 2 implementation in a MS.
An example of a functional composition of the MS Layer 2 is given in 3GPP TS 04.05. These function blocks provide basic capabilities which have to be implemented in accordance with 3GPP TS 04.05 and 3GPP TS 04.06.
Also there are alternatives or options included in 3GPP TS 04.05 and 3GPP TS 04.06, these are provided as complementary capabilities.

51.010-1
|
25.1.3 Pre-conditions
|
Before carrying out any Layer 2 tests the tests specified in clauses 12, 13, 14 and 15 to 23 (Layer 1 tests) shall be performed.
Apart from powering up the MS to be tested and being able to establish a call the only access to the MS needed and used for Layer 2 testing is the radio interface. It therefore is necessary that the MS is able to synchronize to the System Simulator and to decode its BCCH and CCCH. Furthermore, the MS must be able to perform the following elementary Layer 3 procedures:
- Paging;
- Immediate Assignment;
- Dedicated Channel Assignment;
- Handover;
- Channel Release.
It is necessary that the tests are performed in the order specified, except where the starting point is set (subclause 25.1.5).
The data link is maintained by the MS and the SS sending fill frames (see 3GPP TS 04.06, subclause 5.4.2.3) on the SDCCH when no other frames are to be transmitted. Fill frames are also sent on the FACCH while the channel mode is set to signalling. The default mode is signalling. The tests will normally be performed with the MS sending fill frames on the main DCCH (i.e. FACCH or SDCCH). Consequently throughout the tests fill frames will be sent and received even while waiting for other Layer 2 frames. The scheduling of the fill frame sending cannot be specified as this sending is closely linked to the processing times in the MS. Therefore, the instants of transmission of fill frames cannot be tested nor the number of these transmissions however, in certain circumstances, the fact that a fill frame is sent can be used as proof that the MS requirement has been fulfilled.

|
51.010-1
|
25.1.4 Layer 2 test frames
|
The Layer 2 conformance test is accomplished by sequences of those frames which are contained in 3GPP TS 04.06 (Layer 2 frame repertoire etc.).
These frame sequences are under control of the System Simulator and are related to the state that the System Simulator perceives the MS to be in as a result of frames transferred across the MS-BS interface.
These frame sequences shall comply with the following rules:
1) The test sequences exchanged between the System Simulator and MS are assumed to be free from transmission errors.
2) The tester may introduce errors in the direction tester to MS by inserting wrong parameters in the address, control and length indication field.
3) The tester may simulate errors in the direction MS to tester by ignoring the receipt of frames from the MS.
4) The tester may violate the protocol rules related to the control of state variables to provoke sequence gaps.
5) There is no contention on the Dm channel at Layer 1 (Layer 1 point-to-point).
6) With respect to contention on the Dm channel at Layer 2, two distinct situations are defined:
i) Test of the protocol procedure supported by a single entity. In this case there is no contention on the Dm channel (one peer-to-peer information transfer invoked at a time). This test applies to all MSs and is performed for SAPI = 0.
ii) Test of Layer 2 multiplexing and MS processing capacity in terms of the number of SAPs and links which a MS is able to support simultaneously. In this case there is contention on the Dm channel at Layer 2 and this contention is resolved within Layer 2 based on the SAPI. This test applies to MSs which are designed for supporting SAPI in addition to SAPI = 0.
Examples of special GSM Layer 2 functions to be tested:
- Correct L2 functions on specific GSM control channels;
- Length indication;
- Segmentation, more data bit;
- SABM/UA containing information for contention resolution;
- Abnormal release.

25.1.5 Establishment of the dedicated physical resource
|
The System Simulator shall simulate a BS with BCCH/CCCH on one carrier. The MS shall be listening to this CCCH and able to respond to paging messages. The system simulator sends Paging Request to the MS on the paging channel. The MS shall respond with Channel Request on the random access channel. The system simulator sends Immediate Assign to the MS, thereby ordering the MS either to a SDCCH or to a TCH, that is FACCH. Each test is performed once on SDCCH, once on FACCH/F and once on FACCH/H if the MS supports half-rate. However tests that explicitly check SDCCH and FACCH are performed once if the MS does not support half-rate and twice (once with FACCH/F and once with FACCH/H) if the MS supports half-rate.

25.1.6 Release of the dedicated physical resource
|
After a test has been performed the System Simulator shall initiate the release of the SDCCH or FACCH, as laid out in 3GPP TS 04.08 / 3GPP TS 23.108, subclause 7.1.6. This shall return the MS to the idle mode, i.e. the MS shall again be listening to the CCCH of the System Simulator.

25.2 Test sequences
|
Timing requirement:
The MS shall respond to a command within T200 as defined in 3GPP TS 04.06.
The MS shall repeat a command after time-out of T200 if the command has not been acknowledged as defined in 3GPP TS 04.06.
Constant bit values:
In each frame from the MS:
- bits 6 through 8 of the address field shall be set to zero as defined in 3GPP TS 04.06.
- except for test 25.2.7, the address extension bit (EA bit) shall be set to 1 as defined in 3GPP TS 04.06.
- except for test 25.2.7, the length indicator field extension bit (EL bit) shall be set to 1 as defined in 3GPP TS 04.06.
This shall be checked each time a frame from the MS is received.
Fill bits:
The fill bits transmitted with each frame from the MS whose length indicator L is less than N201 as defined in 3GPP TS 04.06 shall be set as defined in 3GPP TS 04.06.
Frame format description
The frames are described by the following parameter sets:
SABM (C, P, M = 0, L = 0) (* SABM without an information field*)
SABM (C, P, M = 0, L > 0) (* SABM with an information field*)
DISC (C, P, M = 0, L = 0)
UA, (F, M = 0, L = 0) (* UA without an information field*)
UA, (F, M = 0, L > 0) (* UA with an information field*)
DM (R, F, M = 0, L = 0)
RR (C, P, M = 0, L = 0, N(R))
RR (R, F, M = 0, L = 0, N(R))
REJ (C, P, M = 0, L = 0, N(R))
REJ (R, F, M = 0, L = 0, N(R))
I (C, P, M = 0, L < N201, N(S), N(R))
I (C, P, M = 1, L = N201, N(S), N(R))
UI (C, P = 0, M = 0, L = 0)
UI (C, P = 0, M = 0, L < N201)
where:
C = command

The MS is paged as described in the general section for Layer 2 testing in subclause 25.1.5. The MS is now in a condition to test the Layer 2 aspects of multiple frame establishment with contention resolution and a UA frame with an information field different from the one in its SABM frame.
The MS shall send an SABM frame.
The SS shall respond with an UA frame whose information field is different from the one in the SABM frame.
The MS shall send an SABM frame.
The SS shall respond with an UA frame whose information field is different from the one in the SABM frame.
The SS shall wait for 3 T200 to check that the MS does not send any L2 frames other than L2 fill frames on the assigned channel.
After a time equal to 3 T200 the SS checks that there are no more Layer 2 frames on the assigned channel, for a period of 1 s.
NOTE 1: Possible fill frames are allowed in order to take into account processing time inside the MS.
NOTE 2: There are no further attempts of immediate assignment procedure after the repetition.
15 s after sending the UA frame in response to the repetition of the immediate assignment procedure the SS pages the MS according to subclause 25.2.1.1.1, to make sure that the MS has returned to the idle state.

25.2.1.2.4.2 Method of test
|
The data link is setup between the MS and the SS as in test 25.2.1.1.1.
After the MS has sent the UI frame the SS initiates the dedicated channel assignment procedure to assign a SDCCH.
The MS shall then continue the setup by sending a SABM frame.
The SS ignores the first SABM frame from the MS.
The MS shall wait for time-out of timer T200 and then send a second SABM frame.
This is repeated until the MS has sent the SABM frame six times.
The MS shall not send the SABM any more than six times.
The test is repeated, but a FACCH is assigned in place of the SDCCH.

The frames from the MS shall be:
1: One SABM frame (occurs six times) containing:
SAPI = 0, C = 0, P = 1, M = 0, L = 0.
The subsequent SABM frames shall follow the previous SABM frame after time-out of timer T200.

25.2.2.1.2 Method of test
|
The MS is brought into the multiple frame established state as described in test 25.2.1.1.1.
The SS sends an Identity Request message asking for IMEI to the MS.
The MS shall acknowledge this I frame with an Identity Response I frame or a RR frame.
This is repeated a further 8 times as rapidly as possible assuming a window size 1.
The MS Layer 3 response time should be less than 4*T200 and therefore the MS responses to at least the 5th, 6th, 7th, 8th and 9th I frames must be an I frame on the SDCCH. On the FACCH it is possible that all MS responses at Layer 2 will be RR frames.
The frames from the SS will be:
1, 3, 5, 7, 9, 11, 13, 15, 17: One I frame (occurs nine times) containing:
SAPI = 0, C = 1, P = 0, M = 0, 0 L N201.
N(S) = 0, 1, 2, 3 .... 7, 0.
N(R) = (number of I frames received in the test sequence hitherto) mod 8.
information field = Identity Request (IMEI).
19, 21, and so on, until the SS has received 9 I frames from the MS: One RR frame containing:
SAPI = 0, R = 0, F = 0, M = 0, L = 0.
N(R) = (number of I frames received in the test sequence hitherto) mod 8.

25.2.2.1.3 Test requirements
|
There shall be an integer k >= 0 such that for i = 1, 2, ...., k + 9 the following conditions (a) and (b) both hold:
(a) The MS sends 9 I frames and k RR frames during the test.
(b) The frames sent by the MS in step 2i are:
(b1) If the frame is an RR frame (occurs k times): one RR frame containing:
SAPI = 0, R = 1, F = 0, M = 0, L = 0.
N(R) = ((Value of N(S) in the last received I frame from the SS) + 1) mod 8.
(b2) If the frame is an I frame (occurs 9 times): one I frame containing:
SAPI = 0, C = 0, P = 0, M = 0, 0 <= L <= N201.
N(R) = ((Value of N(S) in the last received I frame from the SS) + 1) mod 8.
N(S) = (number of I frame sent hitherto by the MS to SS excluding the actual I frame) mod 8.
information field = Identity Response (IMEI).
