Test Procedure
The SS sends an IMMEDIATE ASSIGNMENT REJECT on the MS's paging subchannel, with the page mode element set to "extended paging". In the next but one subblock on the same CCCH, nothing addresses the MS. When the MS's specific paging subchannel reoccurs, a PAGING REQUEST TYPE 3 is sent, not addressing the MS under test and with page mode set to "same as before". In the next but one subblock on the same CCCH the SS sends a PAGING REQUEST TYPE 1 message specifying paging reorganization and addressing the MS. The MS shall respond by sending CHANNEL REQUESTs. The SS responds to the second CHANNEL REQUEST with an IMMEDIATE ASSIGNMENT REJECT (in order to avoid a cell reselection).

|
Initial Conditions
System Simulator:
1 cell, a legal combination of CCCH_CONF, BS_AG_BLKS_RES and BS_PA_MFRMS is chosen arbitrarily under the following constraint:
CCCH_CONF is in the set:
- 2 basic physical channels used for CCCH, not combined with SDCCHs
- 3 basic physical channels used for CCCH, not combined with SDCCHs
- 4 basic physical channels used for CCCH, not combined with SDCCHs
Mobile Station:
The IMSI last 3 digits are so that the CCCH_GROUP of the MS under test is other than 0. According to subclause 6.5.2 of recommendation 3GPP TS 05.02, this means that:
(IMSI mod 1000) mod (BS_CC_CHANS X N) is greater or equal to N, where
N = BS_PA_MFRMS X (9 - BS_AG_BLKS_RES).
The MS is in the "idle, updated" state.
Specific PICS statements
-
PIXIT statements
-
Foreseen Final State of the MS
"Idle updated".
Test Procedure
The SS pages the MS once with a PAGING REQUEST TYPE 1 message on the timeslot and paging subchannel which correspond to the MS's IMSI.
The MS shall send the CHANNEL REQUEST on the same timeslot as the paging message.
The SS sends an IMMEDIATE ASSIGNMENT on the same timeslot as the paging message.

26.6.2.6.1 Conformance requirements
|
Upon receipt of a paging request message, or other message containing information to trigger the establishment of a RR connection, and if access to the network is allowed, the addressed mobile station shall, when camped on a cell as specified in 3GPP TS 23.022, initiate the immediate assignment procedure as specified in sub-clause 3.3.1. The establishment of the main signalling link is then initiated by use of an SABM with information field containing the PAGING RESPONSE message (see sub-clause 3.1.5). The MM sublayer in the mobile station is informed that the RR entity has entered the dedicated mode.
For a mobile originated access attempt, a mobile station configured for EAB shall perform a preliminary access barring check (see sub-clause 3.3.1.4). If the preliminary access barring check indicates network access is barred then access to the network is not allowed. Otherwise, the mobile station shall proceed according to the remainder of this sub-clause.

Since when k = 1, SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION TYPE 6 and MEASUREMENT REPORT (and when k = 2 an additional SYSTEM INFORMATION TYPE 5bis is included) are sent continuously, a table is not applicable in this test. The interval between 2 successive Layer 2 frames containing MEASUREMENT REPORTs shall not exceed one Layer 2 frame.

With the exception of the Cell Allocation, the rest of the parameters for all eight cells are the same as the default settings and default SYSTEM INFORMATION TYPE 1 to 4 message contents for cell A. The Cell Allocation for the serving cell is the same as the default setting for cell A. The Cell Allocations for the neighbour cells need have only one entry, consisting of the ARFCN of that cell's BCCH.
NOTE 1: The BA sent in SYSTEM INFORMATION TYPE 5 does not include N1, N4 and N5. N1 may be the case of a barred cell, N3 simulates the case where another operator is transmitting on the same frequency (e.g. in border areas), N4 & N5 simulate the case where other operators are transmitting on other frequencies.
Mobile Station:
The MS is in the active state of a call (U10).
Specific PICS statements
-
PIXIT statements
-
Foreseen Final State of the MS
Active state of a call (U10).
Test Procedure
This test procedure is performed twice.
With the MS having a call in progress, the SS sends SYSTEM INFORMATION TYPE 5 and 6 (on the second iteration of the test the SS also sends SYSTEM INFORMATION TYPE 5bis) on the SACCH. 5 of the 8 BCCHs "on air" are indicated in the BA. The MS shall send MEASUREMENT REPORTs back to the SS, and it shall be indicated in these that measurement results for the 4 strongest permitted carriers have been obtained (one of the carriers in the BA belongs to a non-permitted NCC).
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This sequence is performed for execution counter, k = 1, 2.
Since when k = 1 SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION TYPE 6 and MEASUREMENT REPORT (and when k = 2 an additional SYSTEM INFORMATION TYPE 5bis is included) messages are sent continuously, a table is not applicable in this test. The interval between 2 successive Layer 2 frames containing MEASUREMENT REPORTs shall not exceed one Layer 2 frame.

In the serving cell, the DTX indicator is set to "MS shall use discontinuous transmission".
With the exception of the Cell Allocation, the rest of the parameters for all eight cells are the same as the default settings and default SYSTEM INFORMATION TYPE 1 to 4 message contents for cell A. The Cell Allocation for the serving cell is the same as the default setting for cell A. The Cell Allocations for the neighbour cells need have only one entry, consisting of the ARFCN of that cell's BCCH.
Mobile Station:
The MS is in the active state of a call (U10).
The MS has just completed a handover into the serving cell, S1.
Specific PICS statements
-
PIXIT statements
-
Foreseen Final State of the MS
Active state of a call (U10).
Test Procedure
This test procedure is performed twice.
With the MS having a call in progress on an arbitrary cell, the MS is handed over to cell S1. On cell S1, the SS sends SYSTEM INFORMATION TYPE 5 and 6 (on the second iteration of the test the SS also sends SYSTEM INFORMATION TYPE 5bis) on the SACCH with all 8 of the BCCHs "on air" indicated in the BA. Cell S1 also indicates that DTX shall be used. The MS shall send MEASUREMENT REPORTs back to the SS, and it shall be indicated in these that measurement results for the 6 strongest carriers have been obtained and that DTX has been used. (The MS is positioned in an environment free from acoustic noise.)
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This sequence is performed twice for execution counter, k = 1, 2.
Since when k = 1, SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION TYPE 6 and MEASUREMENT REPORT (and when k = 2 an additional SYSTEM INFORMATION TYPE 5bis is included) messages are sent continuously, a table is not applicable in this test. The interval between 2 successive Layer 2 frames containing MEASUREMENT REPORTs shall not exceed one Layer 2 frame.

Test Procedure
This test procedure is performed three times.
With the MS having a call in progress, the SS sends SYSTEM INFORMATION TYPE 5, 5bis and 6 on the SACCH. Both of the BCCHs "on air" are indicated in the BA. The MS shall send MEASUREMENT REPORTs back to the SS, and it shall be indicated in these that the appropriate measurement results have been obtained as specified in the Specific Message Contents.
For each iteration of the test the frequency format of the BA list contained in the System Information 5 and 5bis message shall change according to the specific message contents.
Maximum Duration Of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This sequence is performed for execution counter, K = 1, 2, 3.
Since SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION 5bis, SYSTEM INFORMATION TYPE 6 and MEASUREMENT REPORT are sent continuously, a table is not applicable in this test. The interval between 2 successive Layer 2 frames containing MEASUREMENT REPORTs shall not exceed one Layer 2 frame.

Test Procedure
This test procedure is performed once.
With the MS having a call in progress, the SS sends SYSTEM INFORMATION TYPE 5, 5ter & 6 on the SACCH. All 8 of the BCCHs "on air" are indicated in the BA. The MS shall send MEASUREMENT REPORTs back to the SS, and it shall be indicated within 20 s in these that measurement results for the 6 strongest carriers, on which the mobile is asked to report, have been obtained.
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
Since SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION TYPE 5ter, SYSTEM INFORMATION TYPE 6 and MEASUREMENT REPORT are sent continuously, a table is not applicable in this test. The interval between 2 successive Layer 2 frames containing MEASUREMENT REPORTs shall not exceed one Layer 2 frame.

26.6.3.7.1 Conformance requirements
|
The MS shall continuously send MEASUREMENT REPORT messages on every SACCH blocks and the measurement valid indication shall be set to valid (0) within the second block at the latest. The MS shall report a new strongest cell in the measurement report at the latest 5 s after a new strongest cell (which is part of the BA(SACCH)) has been activated under the following network conditions: Initial serving cell at RXLEV= -70 dBm, with 6 neighbours at RXLEV= -75 dBm. Then the new BCCH carrier is switched on at RXLEV= -60 dBm.
NOTE: Because of test equipment limitations it is acceptable to activate the new carrier to replace one of the 6 neighbours.

With the exception of the Cell Allocation, the rest of the parameters for all seven cells are the same as the default settings and default SYSTEM INFORMATION TYPE 1 to 4 message contents for cell A. The Cell Allocation for the serving cell is the same as the default setting for cell A. The Cell Allocations for the neighbour cells need have only one entry, consisting of the ARFCN of that cell's BCCH.
Mobile Station:
The MS is in the active state of a call (U10).

PIXIT statements
-
Foreseen Final State of the MS
Active state of a call (U10).
Test Procedure
The test is performed in two steps a) and b).
Step a)
With the MS having a call in progress, the SS sends SYSTEM INFORMATION TYPE 5 & 6 on the SACCH. All 7 of the BCCHs "on air" are indicated in the BA. The MS shall send MEASUREMENT REPORTs back to the SS, and it shall be indicated within 20 s in these that measurement results for the 6 strongest carriers have been obtained.
Step b)
The SS replaces neighbour cell N1 with neighbour cell N7 with a signal strenght of –60 dBm, in order to have the following new settings:

26.6.3.8.1 Conformance requirements
|
When in dedicated mode or group transmit mode, the mobile station regularly sends either MEASUREMENT REPORT or ENHANCED MEASUREMENT REPORT messages to the network.
The Mobile Station shall use ENHANCED MEASUREMENT REPORT messages instead of MEASUREMENT REPORT messages if that is indicated by the parameter REPORT_TYPE and if at least one BSIC is allocated to each BA (list) frequency
For Enhanced Measurement Reporting, cells shall be reported if they are among the at least 6 strongest carriers, and BSIC is successfully decoded and valid (see sub-clause 10.1.1) or, if indicated by the parameter INVALID_BSIC_REPORTING, with known and allowed NCC part. The neighbour cells shall be reported according to the priority defined in sub-clause 8.4.8.1. For other radio access technology/mode, RXLEV is replaced by the relevant measurement quantity (see sub-clause 8.1.5);
For report with the ENHANCED MEASUREMENT REPORT message, the Neighbour Cell list is the concatenation of the GSM Neighbour Cell list and the 3G Neighbour Cell list (if any).

26.6.3.9.1 Conformance requirements
|
The BA (list) which is the initial basis for the measurements is derived from information received on the BCCH in System Information 2 and optionally 2bis and/or 2ter and on the SACCH in System Information 5 and optionally 5bis and/or 5ter. MEASUREMENT INFORMATION and SI2quater messages may add information for the GSM Neighbour Cell List and provide 3G Neighbour Cell list. The Mobile Station shall use ENHANCED MEASUREMENT REPORT messages instead of MEASUREMENT REPORT messages if that is indicated by the parameter REPORT_TYPE and if at least one BSIC is allocated to each BA (list) frequency.
The network may request the MS to report serving cell and neighbour cell measurements with Enhanced Measurement Report message by the parameter REPORT_TYPE, provided that BSIC for all GSM neighbour cells has been sent to the MS (See 3GPP TS 44.018). This reporting is referred as Enhanced Measurement Reporting.
The MS shall use the SCALE value as indicated by the parameter SCALE_ORD in the MEASUREMENT INFORMATION. The MS shall indicate the used SCALE value in each individual ENHANCED MEASUREMENT REPORT or PACKET ENHANCED MEASUREMEMT REPORTmessage.

Test Procedure
Step a)
With the MS having a call in progress, the SS sends SYSTEM INFORMATION TYPE 5, SYSTEM INFORMATION TYPE 6 and MEASUREMENT INFORMATION messages on the SACCH. The Report Type parameter on the SACCH indicates ENHANCED MEASUREMENT REPORT and SERVING_BAND_REPORTING is set to 3. Serving cell and 4 neighbour cells "on air" are indicated in the BA and no 3G Neighbour Cell Description is indicated in the MEASUREMENT INFORMATION message. The MS shall send ENHANCED MEASUREMENT REPORTs back to the SS, and all carriers present in the BA List shall be indicated within 20 s in these that measurement results.
Step b)
Then the SS sends MEASUREMENT INFORMATION message including the request the use of SCALE_ORD parameter. The MS shall send Enhanced Measurement Report back to the SS and indicate the use of SCALE_ORD parameter. The SS checks that the offset is correctly applied by the MS.
Maximum Duration of Test
5 minutes.
Expected Sequence
Since System Information 5, System Information 6 and Measurement Information are sent on SACCH a table is not applicable in this test.

26.6.4 Test of the channel assignment procedure
An intracell change of channel can be requested by upper layers in order to change the channel type, or it may be initiated by the RR-sublayer, e.g. for an intra cell handover. This change is performed using the channel assignment procedure. If the procedure is incorrectly implemented in the MS, the establishment and maintenance of connections is endangered. This applies for the successful case and for the assignment failure: the MS's correct return to the old channel after assignment failure is a necessary part of the GSM system design.

|

|
26.6.4.1.1 Conformance requirements
|
1. Upon receipt of the ASSIGNMENT COMMAND message, the mobile station initiates a local end release of link layer connections, disconnects the physical channels, commands the switching to the assigned channels and initiates the establishment of lower layer connections (this includes the activation of the channels, their connection and the establishment of the main signalling links).
2. MM-messages and CM-messages using SAPI=0 sent from the mobile station to the network can be duplicated by the data link layer in the following case:
- a channel change of dedicated channels is required (assignment or handover procedure) and the last layer 2 frame has not been acknowledged by the peer data link layer before the mobile station leaves the old channel.
In this case, the mobile station does not know whether the network has received the message correctly. Therefore, the mobile station has to send the message again after the new dedicated channel is established.
3. An ASSIGNMENT COMMAND message may indicate a frequency change in progress, with a starting time and possibly alternative channel descriptions.
In the case of the reception of an ASSIGNMENT COMMAND message which contains only the description of a channel to be used after the starting time, and if the starting time has not already elapsed, the mobile station shall wait up to the starting time before accessing the channel.
4. The MS shall establish the link with the power level specified in the ASSIGNMENT COMMAND message.
The MS shall confirm the power control level that it is currently employing in the uplink SACCH L1 header. The indicated value shall be the power control level actually used by the mobile for the last burst of the previous SACCH period.
5. The MS shall apply the hopping frequencies specified in ASSIGNMENT COMMAND message in the Mobile Allocation IE or the Frequency List IE at the time of accessing the new channel using the last received Cell Allocation.
6. After receipt of the ASSIGNMENT COMMAND the MS shall perform the assignment and return an ASSIGNMENT COMPLETE without undue delay.

26.6.4.1.2 Test purpose
|
1. To verify that upon receipt of an ASSIGNMENT COMMAND, the MS switches to the channel defined in the ASSIGNMENT COMMAND, establishes the link and sends an ASSIGNMENT COMPLETE message. This is tested for an MS supporting TCH in the special cases of a transition.
1.1 from non-hopping SDCCH to hopping TCH/F using a different timeslot;
1.2 from hopping TCH/F to non-hopping TCH/F using a different timeslot;
1.3 from non-hopping TCH/F to non-hopping TCH/F using a different timeslot;
1.4 from non-hopping TCH/F to hopping TCH/H using a different timeslot; this test purpose is only applicable if the MS supports TCH/H;
1.5 from hopping TCH/H to non-hopping TCH/H using a different timeslot; this test purpose is only applicable if the MS supports TCH/H;
1.6 from non-hopping TCH/H to hopping TCH/F using a different timeslot; this test purpose is only applicable if the MS supports TCH/H.
2. To verify that an MS supporting TCH, having sent an MM- or CM message which was not acknowledged on L2 before the channel assignment procedure was initiated and before the MS has left the old channel, repeats that message after completion of the assignment procedure without incrementing N(SD). This is tested in the special case of MM message AUTHENTICATION RESPONSE.
3. To verify that, if an MS supporting TCH has received an ASSIGNMENT COMMAND message which contains only the description of a channel to be used after the starting time, and if the starting time has not already elapsed, the mobile station shall wait up to the starting time before accessing the channel.
4. To verify that an MS supporting TCH, having received an ASSIGNMENT COMMAND, having sent an SABM frame to establish the main signalling link on the assigned channel, reports the power level specified in the ASSIGNMENT COMMAND message, in the uplink SACCH L1 header of the SACCH message sent in the SACCH period following the transmission of the SABM frame.
5. To verify that an MS supporting TCH, having received an ASSIGNMENT COMMAND, is able in the case of frequency hopping to decode the Mobile Allocation and Frequency List IEs correctly and applies the specified frequencies using the correct Cell Allocation.
6. To verify that after receipt of the ASSIGNMENT COMMAND the MS returns an ASSIGNMENT COMPLETE without undue delay.

Mobile Station:

-
Foreseen Final State of the MS
"Idle, updated", with TMSI allocated.
Test Procedure
The SS pages the MS and allocates an SDCCH. Then 2 different channels are assigned with ASSIGNMENT COMMANDs. Each time the MS shall switch to the assigned channel, establish the link and send an ASSIGNMENT COMPLETE message.
Then the SS sends a AUTHENTICATION REQUEST message. The MS shall answer with an AUTHENTICATION RESPONSE message, which is not acknowledged on L2 by the SS. Immediately after the AUTHENTICATION RESPONSE message is received, the SS sends an ASSIGNMENT COMMAND. The MS shall switch to the assigned channel, establish the link with the commanded power level and send as ASSIGNMENT COMPLETE message. Then MS shall repeat the AUTHENTICATION RESPONSE message, with the same N(SD) value.
Then the SS sends an ASSIGNMENT COMMAND, which includes a Starting Time IE. The MS shall react as specified above, but this shall be done at the time specified in Starting Time IE.
For an MS not supporting TCH/H, the SS initiates the channel release procedure and the test ends here. For an MS supporting TCH/H, the channel assignment procedure is performed another three times, with half rate channels involved, and again it is checked that the MS correctly completes the procedures, before the SS initiates the channel release procedure.
Maximum Duration of Test
30 s.
Expected Sequence
NOTE: 3GPP TS 04.08 / 3GPP TS 44.018 appears to be unclear as to whether timer T3240 shall or shall not be started as a result of the AUTHENTICATION REQUEST message sent in step 10. To allow a variety of test equipment implementations, the IDENTITY REQUEST message is included in order to avoid an unexpected expiry of timer T3240 prior to the end of the expected sequence.

26.6.4.2.1.1 Conformance requirements
|
On the mobile station side, if a lower layer failure happens on the new channel before the ASSIGNMENT COMPLETE message has been sent, the mobile station deactivates the new channels, reactivates the old channels, reconnects the TCHs if any and triggers the establishment of the main signalling link. It then sends a ASSIGNMENT FAILURE message, cause "protocol error unspecified" on the main DCCH and resumes the normal operation, as if no assignment attempt had occurred. The operational parameters (e.g. ciphering mode) when returning on the old channel are those applied before the procedure.

Test Procedure
A mobile terminated RR connection is established on an SDCCH. The SS sends an ASSIGNMENT COMMAND message allocating a hopping TCH/F, but does not activate the assigned channels. The MS shall try to activate the new channel (this is not verified) and shall then reactivate the old channel and trigger the establishment of the main signalling link on the old channel. Then the MS shall send an ASSIGNMENT FAILURE.
For an MS not supporting TCH/H, the SS initiates the channel release procedure and the test ends here. For an MS supporting TCH/H, the test sequence is repeated another two times, with half rate channels involved, and again it is checked that the MS correctly returns to the old channels, before the SS initiates the channel release procedure.

26.6.5 Test of handover
|
With the Handover procedure, it is possible to completely alter the channels allocated to a MS. This makes it possible in particular to switch a call in progress from one cell to another. The procedure is always initiated by the network and with the MS in a dedicated mode.
Subclauses 26.6.5.1 to 26.6.5.4 contain generic test procedures to be used for executing successful Handover tests. Table 26.6‑1 contains a summary of the different combinations of parameters which have to be tested, together with a reference to the appropriate generic test procedure. If a test uses a channel rate which the MS under test does not support, the test shall be skipped.

26.6.5.1.1 Conformance requirements
|
The MS shall correctly apply the handover procedure in the non-synchronized case when a call is in progress and when handover is performed from a TCH/F without frequency hopping towards a TCH/F without frequency hopping.
The MS shall correctly apply the handover procedure in the non-synchronized case when a call is in progress and when handover is performed from a TCH/H without frequency hopping to a TCH/H with frequency hopping. This does not apply to MSs not supporting TCH/H.

26.6.5.1.2 Test purpose
|
To test that when the MS is ordered to make a non-synchronized handover it continuously sends access bursts on the main DCCH (and optionally the SACCH) until it receives a PHYSICAL INFORMATION message from the SS. To test that the MS correctly handles the values of any Starting Time IE in the HANDOVER COMMAND message in the case when none of the information elements referring to before the starting time are present. To test that the MS correctly handles the Timing Advance IE in the PHYSICAL INFORMATION message. To test that the MS activates the new channel correctly and transmits the HANDOVER COMPLETE message without undue delay.

Range 256
The frame numbers of cells A and B shall be different by 100.
The timebase of cells A and B shall be such that the edges of their timeslots are not coincident at the antenna connector.
Mobile Station:
The MS is in the active state (U10) of a call on cell A.
Specific PICS statements
- MS supports Speech (TSPC_TS1x_Speech)
PIXIT statements
- supported radio interface rates: 12kbps, 6kbps, 3,6kbps
Foreseen Final State of the MS
The active state (U10) of a call on cell A.
Test Procedure
This procedure is repeated for execution counter M = 1 to 8 (see table 26.6‑1).
The MS is in the active state (U10) of a call. The SS sends a HANDOVER COMMAND on the main DCCH. The MS shall (at the time defined by the Starting Time information element, if included in the message) begin to send access bursts on the new DCCH (and optionally the SACCH) of the target cell. The SS observes the access bursts and after receiving n (n being arbitrarily chosen between values according to table 26.6‑2 of subclause 26.6.5) access bursts, the SS sends one PHYSICAL INFORMATION message with a Timing Advance as specified in table 26.6‑1 of subclause 26.6.5. The MS shall activate the channel in sending and receiving mode. The MS shall establish a signalling link. The MS shall be ready to transmit a HANDOVER COMPLETE message, before "x" MS after the end of the PHYSICAL INFORMATION message, but not before a UA frame has been sent by the SS.
The term "ready to transmit" is defined in 3GPP TS 04.13. The value of "x" depends upon the target channel and is specified in the specific message contents section.
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This sequence is performed for an execution counter M = 1, 2, 3 for an MS which only supports TCH/F.
This sequence is performed for an execution counter M = 1, 2.. 8 for an MS which supports TCH/F and H

26.6.5.2.1 Conformance requirements
|
The MS shall correctly apply the handover procedure from SDCCH/8, TCH/F or TCH/H with or without frequency hopping to SDCCH/8, TCH/F or TCH/H with or without frequency hopping in the non-synchronized case during call establishment. The mobile shall correctly apply the handover procedures from non frequency hopping SDCCH/4 to SDCCH/8, TCH/F or TCH/H with or without frequency hopping. If during call establishment a Layer 3 MM or CC message just sent by the MS is not Layer 2 acknowledged before the channel change caused by the HANDOVER COMMAND message, the MS shall send the Layer 3 message to the new cell, using the same value in the N(SD) field, after the handover procedure.

26.6.5.2.2 Test purpose
|
To test that when the MS is ordered to make a non-synchronized handover, it continuously sends access bursts on the main DCCH (and optionally the SACCH) until it receives a PHYSICAL INFORMATION message from the SS. To test that the MS correctly takes the values of the Timing Advance information element in the PHYSICAL INFORMATION message into account. To test that the MS activates the new channel correctly and transmits the HANDOVER COMPLETE message without undue delay. To test that the MS correctly retransmits Layer 3 MM or CC messages, that were not acknowledged by Layer 2 before the Handover, after completion of the Handover.

Mobile Station:
The MS is in the "idle, updated" state, with a TMSI allocated and camped on cell A.
Specific PICS statements
- MS supports Speech (TSPC_TS1x_Speech)
PIXIT statements
- supported radio interface rates: 12kbps, 6kbps, 3,6kbps
Foreseen Final State of the MS
"Idle, updated" with TMSI allocated and camped on cell B.
Test Procedure
This procedure is repeated for execution counter M = 1, 2 .. 10 (See table 26.6‑1.)
A Mobile Originating Call is initiated on Cell A. After the MS has sent the SETUP message (and before the last L2 frame carrying the SETUP message is acknowledged by the SS) the SS sends a HANDOVER COMMAND message, ordering the MS to switch to cell B. The MS shall then begin to send access bursts on the new DCCH (and optionally the SACCH) to cell B. The SS observes the access bursts and after receiving n (n being arbitrarily chosen between values according to table 26.6‑2 of subclause 26.6.5) access bursts, the SS sends one PHYSICAL INFORMATION message with a Timing Advance as specified in table 26.6‑1 of subclause 26.6.5. The MS shall activate the channel in sending and receiving mode. The MS shall establish a signalling link. The MS shall be ready to transmit a HANDOVER COMPLETE message before x ms after the end of the PHYSICAL INFORMATION message, but not before a UA frame has been sent by the SS. The MS shall then again send the SETUP message to the SS, using the same value in the N(SD) field. Finally the SS sends a CHANNEL RELEASE to end the test.
The term "ready to transmit" is defined in 3GPP TS 04.13. The value of "x" depends upon the target channel and is specified in the specific message contents section.
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
The sequence is performed for execution counter M = 1, 2..10 (unless a particular TCH is not supported).

26.6.5.3.2 Test purpose

To test that when the MS is ordered to make a finely synchronized handover to a synchronized cell, it sends 4 access bursts on the main DCCH (and optionally on the SACCH) and then activates the channel correctly, taking into account the value of any Starting Time information element, power command and correctly calculating the timing advance to use. To test the MS activates the new channel correctly and transmits the HANDOVER COMPLETE message without undue delay.

Mobile Station:
The MS is in the active state (U10) of a call (on cell A). The MS is using a power level P. Where P is a power level within the supported range of that type of MS.
Specific PICS statements
• TSPC_Type_xxx (all appropriate power classes)
• MS supports Speech (TSPC_TS1x_Speech)
PIXIT statements
- supported radio interface rates: 12kbps, 6kbps, 3,6kbps
Foreseen Final State of the MS
The active state (U10) of a mobile call (on cell B).
Test Procedure
This procedure is repeated for execution counter M = 1 to 2. (See table 26.6‑1.)
The MS is in the active state (U10) of a call on cell A. The SS sends a HANDOVER COMMAND on the main DCCH. The MS shall (at the time specified in the Starting Time information element, if included) send 4 access bursts, in 4 successive slots on the new DCCH to cell B (Note: Before completion of the 4 access bursts on the DCCH, additional access bursts may also be sent on the SACCH). Then the MS shall establish a signalling link indicating the correct Timing Advance and power level and send a HANDOVER COMPLETE message.
The MS shall be "ready to transmit" a HANDOVER COMPLETE message before "x" ms after the end of the HANDOVER COMMAND message, but not before a UA frame has been sent by the SS.
The term "ready to transmit" is defined in 3GPP TS 04.13. The value of "x" depends upon the target channel and is specified in the specific message contents section.
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This sequence is performed for execution counter M = 1 for an MS which only supports TCH/F.
This sequence is performed for execution counter M = 1 to 2 for an MS which supports TCH/F and H.

Mobile Station:
The MS is in the "idle, updated" state, with a TMSI allocated and camped on cell A. The MS is using a power level P, where P is a power level within the supported range of that type of MS.
Specific PICS statements
• MS supports Speech (TSPC_TS1x_Speech)
• TSPC_Type_xxx (all appropriate power classes)
PIXIT statements
- supported radio interface rates: 12kbps, 6kbps, 3,6kbps
Foreseen Final State of the MS
"Idle, updated" with TMSI allocated and camped on cell B.
Test Procedure
This procedure is repeated for execution counter M = 1, 2, 3, 4 (see table 26.6‑1).
A Mobile Originating Call is initiated on cell A. After the MS has sent the SETUP message (and before the last L2 frame carrying the SETUP message is acknowledged by the SS) the SS sends a HANDOVER COMMAND message, ordering the MS to switch to cell B. The MS shall then (at the time specified in the Starting Time information element, if included) send 4 access bursts, in successive slots on the new DCCH to cell B (Note: Before completion of the 4 access bursts on the new DCCH, additional access bursts may also be sent on the SACCH). Then the MS shall establish a signalling link indicating the correct timing advance and power level and send a HANDOVER COMPLETE message. The MS shall be "ready to transmit" the HANDOVER COMPLETE message before "x" ms after the end of the HANDOVER COMMAND message, but not before a UA frame has been sent by the SS. The MS shall then again send the SETUP message to the SS, using the same value in the N(SD) field. Finally the SS sends a CHANNEL RELEASE to end the test.
The term "ready to transmit" is defined in 3GPP TS 04.13. The value "x" depends upon the target channel and is specified in the specific message contents section.
Maximum Duration of Test
5 minutes, including 1 minute for any necessary operator actions.
Expected Sequence
This procedure is repeated for execution counter M = 1, 2, 3, 4 (unless a particular TCH is not supported).

Initial Conditions
System Simulator:
2 cells, A and B, with same LAI, default parameters.
The BCCH of cell A is sent k bit periods before the BCCH of cell B. k is arbitrarily selected.
Mobile Station:
The MS is in the active state (U10) of a call (on cell A) using a full rate TCH in non-hopping mode.
Specific PICS statements
-
PIXIT statements
-
Foreseen Final State of the MS
The active state (U10) of a mobile call (on cell B) using a full rate TCH in non-hopping mode.
Test Procedure
The MS is in the active state (U10) of a call on cell A. The SS sends a HANDOVER COMMAND for a pre-synchronized handover without the Timing Advance IE on the main DCCH. The MS shall send 4 access bursts, in 4 successive slots of the new DCCH to cell B with a Timing Advance of zero (Note: Before completion of the 4 access bursts on the new DCCH, additional access bursts may also be sent on the SACCH). Then the MS shall establish a signalling link using a Timing Advance of one and send a HANDOVER COMPLETE message. The MS shall be ready to transmit the HANDOVER COMPLETE message before 650 ms after the end of the HANDOVER COMMAND message, but not before a UA frame has been sent by the SS.
The term "ready to transmit" is defined in 3GPP TS 04.13.
Maximum Duration of Test

Initial Conditions
System Simulator:
2 cells, A and B, with same LAI, default parameters.
The BCCH of cell A is sent k bit periods before the BCCH of cell B.
Mobile Station:
The MS is in the "idle, updated" state, with a TMSI allocated and camped on cell A.
Specific PICS statements
-
PIXIT statements
-
Foreseen Final State of the MS
"Idle, updated" with TMSI allocated and camped on cell B.
Test Procedure
A Mobile Originating Call is initiated. The SS sends an IMMEDIATE ASSIGNMENT message allocating an SDCCH/4. The MS is commanded to use a timing advance of y bit periods on cell A. After the MS has sent the SETUP message (and before the last L2 frame carrying the SETUP message is acknowledged by the SS) the SS sends a HANDOVER COMMAND, ordering the MS to switch to cell B. The MS shall then send 4 access bursts, in 4 successive slots of the new DCCH to cell B (Note: Before completion of the 4 access bursts on the new DCCH, additional access bursts may also be sent on the SACCH). Then the MS shall establish a signalling link using the correct timing advance and send a HANDOVER COMPLETE message. The MS shall be ready to transmit the HANDOVER COMPLETE message before 650 ms after the end of the HANDOVER COMMAND message, but not before a UA frame has been sent by the SS.
The term "ready to transmit" is defined in 3GPP TS 04.13.
The MS shall then again send the SETUP message to the SS, using the same value in the N(SD) field. Finally the SS sends a CHANNEL RELEASE to end the test.
