26.16 Adaptive Multi Rate Signalling

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

The purpose of this subclause is to test the different procedures, which may be impacted by the multi rate codec.

26.16.0 Default contents of layer 3 messages for AMR signalling tests

Refer to table 26.6.

26.16.1 Void

26.16.2 Inband Signalling, Uplink Codec Adaptation

26.16.2.1 Conformance Requirement

The MS shall after reception of a Codec Mode Command apply the corresponding codec mode in the uplink direction for the next possible speech frame and no more than three speech frames later. This test is not intended to verify these conformance requirements, but to verify the correctness of the involved layer 1 and layer 3 signalling.

References:

3GPP TS 05.09 subclauses 3.3 and 3.4.

26.16.2.2 Test Purpose

This test is concerned with the link adaptation for AMR uplink and the related inband signalling. The test shall verify that the MS in the uplink direction applies the codec mode indicated by the network transmitted Codec Mode Commands, and that the MS correctly signals the used codec as Codec Mode Indication in the uplink inband signalling.

NOTE: The inband signals are L1 signalling transmitted every speech frame, as defined in 3GPP TS 05.09: In uplink directions Codec Mode Requests and Codec Mode Indications are transmitted alternately, whereas downlink signalling contains of alternately Codec Mode Commands and Codec Mode Indications.

26.16.2.3 Method of Test

Initial Conditions

The MS is "idle updated", with TMSI allocated.

Specific PICS statements:

– Speech supported for Half rate version 3 (HR AMR).

PIXIT statements:

Foreseen Final State of MS

"Idle, updated", with TMSI allocated.

Test Procedure

a) A mobile originated call is initiated, following the CHANNEL REQUEST received from the MS the SS sends an IMMEDIATE ASSIGNMENT to the MS commanding it to go to a SDCCH. The MS indicates to the SS that it supports the multi-rate speech codec. The SS allocates the MS a TCH/AFS and signals the allowed codec subset and adaptation thresholds as part of the ASSIGNMENT COMMAND. DTX shall not be activated. Hopping is activated. The hopping band is centred around an ARFCN in the Mid ARFCN range. The hopping frequencies are chosen from those defined in clause 6.

The following active codec mode subset shall apply:

Codec Mode

TCH/AFS in kbit/s

CODEC_MODE_1

CODEC_MODE_2

5,9

CODEC_MODE_3

b) The SS signals that a new codec is wanted in uplink direction by changing the value of the Codec Mode Command. The MS shall apply the commanded mode in uplink by changing the mode and correspondingly the value of the Codec Mode Indication to match the used codec. This is repeated for all neighbouring mode transitions in the Active Codec Set.

c) If the MS supports TCH/AHS the SS sends an ASSIGNMENT COMMAND allocating the MS a TCH/AHS and signals the allowed codec subset and adaptation thresholds as part of the ASSIGNMENT COMMAND. DTX shall not be activated. Hopping is activated. The hopping band is centred around an ARFCN in the Mid ARFCN range. The hopping frequencies are chosen from those defined in clause 6.

The following active codec mode subset shall apply:

Codec Mode

TCH/AHS in kbit/s

NOTE: This test is derived from the one described in subclause 26.12 and entitled: "Structured procedures / MS terminated call / early assignment".

26.16.4.1 Conformance requirement

1) The MS shall indicate and include in the mobile originating SETUP for speech call all the speech versions that it supports.

2) Upon receipt of the ASSIGNMENT COMMAND message using full rate version 3 or half rate version 3, the Mobile Station starts a normal channel assignment procedure. It means that the MS 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 data links). After the main signalling link is successfully established, the MS returns an ASSIGNMENT COMPLETE message, specifying cause ‘normal event’, to the network on the main DCCH.

NOTE: This test is derived from the one described in subclause 26.16.4 and entitled: "Structured procedures / MS originated call / late assignment / specified initial codec mode".

26.16.4a.1 Conformance requirement

1) The MS shall indicate and include in the mobile originating SETUP for speech call all the speech versions that it supports.

2) Upon receipt of the ASSIGNMENT COMMAND message using full rate version 3 or half rate version 3, the Mobile Station starts a normal channel assignment procedure. It means that the MS 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 data links). After the main signalling link is successfully established, the MS returns an ASSIGNMENT COMPLETE message, specifying cause ‘normal event’, to the network on the main DCCH. The ASSIGNMENT COMMAND message will also specify the subset of codec modes that the MS is allowed to use for the call and the threshold values. The ASSIGNMENT COMMAND will not specify the initial codec mode but will, rather, allow the MS to select the default codec mode.

If the Initial Codec Mode is not signalled, then the default Initial Codec Mode is given by the following implicit rule. If the Active Codec Set contains:

1 mode, then this hall be the Initial Codec Mode.

2 or 3 modes, then the Initial Codec mode shall be the most robust mode of the set (with lowest bit rate).

4 modes, then the Initial Codec Mode shall be the second most robust mode of the set (with second lowest bit rate. If the Active Codec Set is changed during the call, then this default Initial Codec Mode shall used until an other ICM is explicitly signalled.

26.16.5 AMR signalling / Handover / active call / successful case

NOTE: This test is derived from 26.12.2 – EFR Signalling/Handover/active call/successful case.

26.16.5.1 Conformance requirements

The MS shall correctly apply the handover procedure in the non-synchronised case when:

– a call is in progress; and

– handover is performed from a TCH/F with/without frequency hopping towards a TCH/F with/without frequency hopping;

– the mode of either the current or the target channel is set to full rate speech version 3.

The MS also supporting half rate speech version 3 shall correctly apply the handover procedure in the non-synchronized case when:

– a call is in progress; and

– a handover is performed between a TCH/H with/without frequency hopping and a TCH/F or TCH/H with/without frequency hopping; and

– the mode of either the current or the target channel is set to half rate speech version 3.

26.16.5.2 Test Purpose

To test that the MS shall correctly apply the handover procedure in the non-synchronized case when:

– a call is in progress; and

– handover is performed from a TCH/F with/without frequency hopping towards a TCH/F with/without frequency hopping; and

– the mode of either the current or the target channel is set to full rate speech version 3 (AMR full rate speech).

To test that the MS also supporting half rate shall correctly apply the handover procedure in the non-synchronized case when:

– a call is in progress; and

– a handover is performed between a TCH/H with/without frequency hopping and a TCH/F with/without frequency hopping; and

– the mode of either the current or the target channel is set to half rate speech version 3.

n: number of access bursts.

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 on 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 2) access bursts, the SS sends one PHYSICAL INFORMATION message with a Timing Advance as specified in table 1. 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

10 minutes.

Expected Sequence

This sequence is performed for an execution counter M = 1, 2..10 for an MS that supports TCH/F and speech version 3, version 2 and version 1. Steps M=7 and M=8 are performed only if an MS supports full rate speech version 2. Steps M=9 and M=10 are performed only if an MS supports half rate speech version 1.

This sequence is performed for an execution counter M = 1, 2..19 for an MS that supports TCH/F and TCH/H and speech version 3, version 2 and version 1. Steps M=7, M=8, M=15 and M=16 are performed only if an MS supports speech version 2. Steps M=9, M=10, M=17 and M=18 are performed only if an MS supports half rate speech version 1.

26.16.6.2 Test purpose

1) To verify that an MS supporting speech in the MM state "idle, updated", when made to call the number 112 (for GSM 900 and DCS 1800 MS), or 911 (for GSM 710, GSM 750, T_GSM 810, GSM 850 and PCS 1 900 MS in USA and Canada), or 08 (for GSM 710, GSM 750, T_GSM 810, GSM 850 and PCS 1 900 MS in Mexico), sends a CHANNEL REQUEST message with establishment cause "emergency call".

2) To verify that after assignment of a dedicated channel the first layer message sent by the MS on the assigned dedicated channel is a CM SERVICE REQUEST message specifying the correct CKSN and TMSI, with CM Service Type "emergency call establishment".

3) To verify that authentication and cipher mode setting are performed successfully.

4) To verify that after cipher mode setting acceptance by the SS, the MS sends an EMERGENCY SETUP message.

5) To verify that the AMR mobile station shall accept channel assignment to a TCH/AF and if it supports half rate, also to a TCH/A depending what the network signals to the mobile and also select the correct codec mode. The call shall be set up using the AMR codec.

6) To verify that subsequently the MS has through connected the TCH in both directions.

7) To verify the call is cleared correctly.

26.16.6.3 Method of Test

Initial Conditions

SS: 1 cell default parameters.

MS: The MS is in the MM-state "idle, updated" with valid TMSI and CKSN.

Foreseen Final State of the MS

The MS is in the MM-state "idle, updated" with valid TMSI and CKSN.

Specific PICS statements:

– Speech supported for Half rate version 3 (HR AMR).

PIXIT statements:

-.

Test Procedure

The MS is made to initiate an emergency call. The call is established with late assignment. Having reached the active state, the call is cleared by the SS. This procedure is repeated so that the assignment is made with full rate and half rate speech versions as supported by the MS.

Maximum Duration of Test

3 minutes.

26.16.7 AMR Signalling / Directed Retry / Mobile Originated Call

NOTE: This test is derived from the one defined in subclause 26.12.6 and entitled "EFR Signalling / Directed Retry / Mobile Originated Call".

26.16.7.1 Conformance requirements

The MS shall correctly apply the Directed Retry procedure from SDCCH/8 (no frequency hopping) to TCH/AMR with frequency hopping in the non-synchronized case during call establishment. The call control entity of the Mobile Station in the "mobile originating call proceeding" state shall, upon receipt of a CONNECT message, attach the AMR speech connection to the radio path and return a CONNECT ACKNOWLEDGE message to the SS.

3GPP TS 04.13, subclause 5.2.6.2.

26.16.7.2 Test purpose

To test that, when the MS is ordered to perform a non-synchronized handover after the CALL PROCEED message, it continuously sends access bursts on the main DCCH (and optionally on 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 call control entity of the Mobile Station in the "mobile originating call proceeding" state, upon receipt of a CONNECT message, attaches the AMR speech connection to the radio path and returns a CONNECT ACKNOWLEDGE message to the SS.

Range 512

The time base of Cells A and B shall be such that the edges of their timeslots are not coincident at the antenna connector.

A non-combined SDCCH is used.

Mobile Station:

The MS is in the "idle, updated" state, with a TMSI allocated and camped on cell A.

Specific PICS statements:

– Speech supported for Half rate version 3 (HR AMR).

PIXIT statements:

– Way to indicate mobile originated alerting.

Foreseen Final State of the MS

"Idle, updated" with TMSI allocated and camped on cell B.

Test Procedure

The MS is made to initiate a speech call on Cell A. After the SS has sent the CALL PROCEEDING message 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 on 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 an arbitrarily chosen Timing Advance. 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. After the successful handover procedure the SS sends the ALERTING message. The correct alerting indication shall be given to the user (only applicable if the MS supports this feature). The SS sends the CONNECT message indicating that the call has been answered. The AMR speech channel shall be through connected in both directions. The MS shall send then the CONNECT ACKNOWLEDGE message as the response on the CONNECT message. Having reached the active state, the call is cleared 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.

26.16.8 AMR Signalling / Directed Retry / Mobile Terminated Call

NOTE: This test is derived from the one defined in subclause 26.12.7 and entitled "EFR Signalling / Directed Retry / Mobile Terminated Call".

26.16.8.1 Conformance requirements

The MS shall correctly apply the Directed Retry procedure from SDCCH/8 with frequency hopping to TCH/AMR with frequency hopping and starting time in the non-synchronized case during call establishment. The call control entity of the Mobile Station in the "call delivered" state shall, if the MS supports immediate connect, continue the call establishment by through-connecting the AMR traffic channel in both directions, or if the MS does not support immediate connect, send an ALERTING message. The MS indicates acceptance of a MT call by sending CONNECT.

The mobile station shall attach the user connection at latest when sending the CONNECT message, except if there is no compatible radio resource available at this time. In this case the attachment shall be delayed until such a resource becomes available.

26.16.8.2 Test purpose

To test that when the MS is ordered to perform a non-synchronized handover after the CALL CONFIRM message, it continuously sends access bursts on the main DCCH (and optionally on 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 call control entity of the Mobile Station in the "call delivered" state, if the MS supports immediate connect, continues the call establishment by through-connecting the AMR traffic channel in both directions, or if the MS does not support immediate connect, sends an ALERTING message. To test that the MS indicates acceptance of a MT call by sending CONNECT.

To test that the mobile station attaches the user connection at latest when sending the CONNECT message, except if there is no compatible radio resource available at this time. To test that in this case the attachment is delayed until such a resource becomes available.

– Speech supported for Half rate version 3 (HR AMR).

– Immediate connect supported for all circuit switched basic services.

PIXIT statements:

– Way to indicate alerting.

– Way to make the MS accept an incoming call after alerting.

Foreseen Final State of the MS

"Idle, updated" with TMSI allocated and camped on cell B.

Test Procedure

The MS is paged on Cell A. The MS responds to the PAGING REQUEST message and establishes a mobile terminated speech call on Cell A. If the MS supports immediate connect, it continues the call establishment by through-connecting the traffic channel in both directions, or if the MS does not support immediate connect, it sends an ALERTING message. The MS indicates acceptance of a MT call by sending CONNECT.

After the MS has sent the CALL CONFIRMED message (if the MS supports immediate connect then the MS sends the CONNECT message after the CALL CONFIRMED message on the old channel) 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 on 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 an arbitrarily chosen Timing Advance. 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. After the successful handover procedure the MS sends the ALERTING message (if the MS runs the immediate connect procedure then the MS does not send an ALERTING message). The correct alerting indication shall be given to the user (only applicable if the MS supports the feature or if the MS is not using the immediate connect procedure). After the MS sent the CONNECT message the AMR speech channel shall be through connected in both directions. The SS sends then the CONNECT ACKNOWLEDGE message as the response on the CONNECT message. Having reached the active state, the call is cleared 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.

Test Procedure

This sequence is performed for execution counter, k = 1, 2.

When k = 1, DTX is not used:

1) User initiates a Mobile Originated call.

2) The network and the MS indicate Bearer capabilities IE with the AMR speech Full Rate and Half Rate (Version 3).

3) The network performs an assignment on a TCH channel with MultiRate configuration to the MS.

4) The call is maintained during a programmable time without variation of RxLev /RxQual.

5) The SS shall send a properly formatted AMR_CONFIG_REQ message during the call at a programmable time.

6) The MS answers with a ACK_OK message within 3 speech frames

7) The network initiates the call release.

When k = 2, DTX is used:

1) In the serving cell, the DTX indicator is set to "MS shall use discontinuous transmission".

2) User initiates a Mobile Originated call.

3) The network and the MS indicate Bearer capabilities IE with the AMR speech Full Rate and Half Rate (Version 3).

4) The network performs an assignment on a TCH channel with MultiRate configuration to the MS.

5) The call is maintained during a programmable time without variation of RxLev /RxQual.

6) The SS shall send a properly formatted AMR_CONFIG_REQ message during the call at a programmable time.

7) The MS answers with a ACK_OK message within 3 speech frames.

8) The network initiates the call release.

This test is repeated for M=1, and where the MS supports half rate version 3 M=2.

26.16.9.11 Change of Active Codec Set

26.16.9.11.1 Conformance requirements

AMR codec mode adaptation is done within a set of 4 codec modes. The codec mode set (Active Codec Set) to be used by the BSS and the MS is defined during call setup and/or handover by layer 3 signalling. The ACS can be changed during a call using an AMR_CONFIG_REQ message sent on the RATSCCH.

The AMR_CONFIG_REQ message may be sent by the BTS during a call to change the AMR configuration on the radio interface without interruption of the speech transmission.

The ACK_OK message serves as an acknowledgement that a RATSCCH REQ message has been detected, correctly decoded (no CRC error) and that it is defined for the Addressee.

If the ACS consists of four modes, then the complete set of thresholds/hysteresis can not be sent with this message. In that case, all THRESHj and HYSTj fields are reserved for future use and shall be set to "1". Similar, if the BTS has no threshold and hysteresis parameters for the given configuration, then all THRESHj and HYSTj field bits shall be set to "1" to indicate that they are undefined. The THRESH_REQ message shall be used to transmit these parameters at a later point in time. As long as the MS has no defined threshold and hysteresis parameters it shall use the Initial Codec Mode for the Codec Mode Request.

References:

3GPP TS  05.09 clauses 3.2.2.3.5 and 3.4.

26.16.9.11.2 Test purpose

This test shall verify that the MS is able to change its Active Codec Set using the RATSCCH protocol, with change of thresholds, and with non-specification of thresholds.

Idle Updated, TMSI allocated and camped on cell A.

Test Procedure

1) User initiates a Mobile Originated call.

2) The network and the MS indicate Bearer capabilities IE with the AMR speech Full Rate and Half Rate (Version 3).

3) The network performs an assignment on a TCH channel with MultiRate configuration to the MS.

4) The SS uses the codec with the highest bit-rate in the current ACS for the Codec Mode Indication, and that with the lowest bit-rate for the Codec Mode Command.

5) The SS sends an AMR_CONFIG_REQ message during the call to reconfigure the Multirate settings.

6) The MS responds to each AMR_CONFIG_REQ message with an ACK_OK message on the RATSCCH.

7) The SS shall ensure that the change occurs correctly for downlink (12 speech frames after AMR_CONFIG_REQ message was sent), and for uplink (12 speech frames after ACK_OK was received) by checking parity of received speech frames, and correct implementation of Uplink Codec mode Request.

8) The SS shall ensure that each of the codecs in the ACS have been implimented correctly by setting the CMC to each of the applicable modes, and ensuring that the UL frames with each CMI are received without parity error. The SS shall then set the CMI and CMC to the codec with highest and lowest bit rates respectively.

9) Steps 4 to 8 shall be repeated for differing AMR_CONFIG_REQ parameters and sending conditions.

10) The network initiates the call release.

This test is repeated for M=1, and where the MS supports half rate version 3 M=2.

Note: This test is derived from 26.6.5.9 Handover / layer 1 failure.

26.16.11.1 Conformance requirements

The MS shall return to the old channel in the case of a handover failure caused by a layer 1 failure on the target cell. On the old channel the MS shall use the AMR Parameters that it was previously using on that channel.

References

3GPP TS 04.08 / 3GPP TS 44.018 section 3.4.4.

26.16.11.2 Test purpose

To verify the contents in the message HANDOVER FAILURE .

To verify the mobile returns to the correct channel configuration prior to handover following the handover failure.

26.16.11.3 Method of test

Initial Conditions

System Simulator:

2 cells with same LAI, default parameters.

Mobile Station:

The MS is in the active state (U10) of a call (on cell A). Used power level is the maximum supported by the MS.

Specific PICS statements:

– Speech supported for Half rate version 3 (HR AMR).

– Speech supported for Full rate version 2 (GSM EFR)

– Speech supported for Half rate version 1 (GSM HR)

PIXIT statements:

-.

Foreseen Final State of the MS

The active state (U10) of a mobile call (on cell A). Used power level is the maximum supported by the MS.

Test Procedure

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 begin to send access bursts at the commanded power level on the new DCCH (and optionally on the SACCH) to cell B. With the exception of normal BCCH signalling, the SS does not transmit anything on cell B (thus causing a time-out of T3124). The MS shall re-establish the old link on cell A and send a HANDOVER FAILURE within 3 seconds from the transmission of HANDOVER COMMAND.

Maximum Duration of Test

10 minutes

Expected Sequence

This test is repeated for M=1, M=2 (only if MS supports half rate version 3), M=3, M=4, M=5 (only if MS supports half rate version 3), M=6 (only if MS supports half rate version 3), M=7 (only if MS supports full rate version 2), M=8 (only if MS supports half rate version 1).

This test is repeated for K=1, K=2 (only if MS supports half rate version 3).
