70.7.4.1.1 Conformance requirements

1. With the MS in the "idle, updated" state, the user shall initiate an emergency after the number 112 (for GSM900 and 1800 MS), or 911 (for PCS 1900 MS in the USA), or 08 (for PCS 1900 MS in Mexico) has been entered by the user. The MS shall send a CHANNEL REQUEST message with correct establishment cause ("emergency call").

2. When a user requests an emergency call establishment the mobile station will send a CM SERVICE REQUEST message to the network with a CM service type information element indicating emergency call establishment and the correct CKSN and TMSI. A mobile station which implements the “LCS” option shall also implement the “Controlled Early Classmark Sending” option. A mobile station which implements the “Controlled Early Classmark Sending” option shall indicate it in the classmark (ES IND bit).

3. After sending the CM SERVICE REQUEST message the MS shall send a CLASSMARK CHANGE message. The “Mobile Station Classmark 3” information element shall correctly specify the positioning methods supported by the MS.

  1. After the CM SERVICE ACCEPT message is received from the network, the MS shall send an EMERGENCY SETUP message.
  2. After receipt of a CONNECT ACKNOWLEDGE message during correct establishment of the emergency call the MS shall indicate that the TCH is through connected in both directions.
  3. On receiving the MEASURE POSITION REQUEST message the MS tries to perform the requested location measurements, and calculates its own position. It sends the results in the RRLP MEASURE POSITION RESPONSE message.

70.7.4.1.2 Test Purpose

To verify when a network instigates the LCS positioning procedure by sending RRLP (Measure Position Request) message, after a traffic channel has been established during an emergency call, the mobile responds with RRLP (Measure Position Response) containing MS location estimate.

70.7.4.1.3 Method of Test

Initial Conditions

System Simulator (SS):

Serving Cell: default parameters.

Satellite signals: default conditions.

Mobile Station (MS):

The MS is in MM-state “idle, updated” with valued TMSI and CKSN.

SIM:

Normal SIM

Specific PICS statements

– TSPC_MS_RRLP_RELEASE

PIXIT statements

Test Procedure

An Emergency Call is initiated with the MS. SIM card is included in the MS.

The emergency call is established with a late assignment.

After receiving the CONNECT ACKNOWLEDGE message from the MS, the SS sends RR APPLICATION INFORMATION messages containing RRLP Assistance Data messages.

The SS then sends an RR APPLICATION INFORMATION message containing an RRLP Measure Position Request on FACCH including assistance data.

Option 1: The MS then performs positioning measurements, and responds with an RR APPLICATION INFORMATION message containing an RRLP Measure Position Response.

Option 2: The MS may request additional assistance data by sending an RRLP Measure Position Response message containing a location error with IE LocErrorReason set to gpsAssDataMissing. If the MS requests additional assistance data that is available in the SS, then the SS provides the requested assistance data in zero, one or more RRLP Assistance Data delivery messages followed by an RRLP Measure Position Request message which may include further assistance data. If the MS requests additional assistance data and the entire requested assistance data is not available in the SS, then the SS repeats the RRLP Measure Position Request message without assistance data. The MS then performs positioning measurements, and responds with an RR APPLICATION INFORMATION message containing an RRLP Measure Position Response.

The call is cleared by the SS.

Maximum duration of the test

5 minutes.

70.7.4.4 Network Induced Location Request Emergency Call on TCH Radio Channel, no IMSI for mobiles supporting MS-Assisted GPS

70.7.4.4.1 Conformance requirements

1. With the MS (no SIM inserted) in the "idle, no IMSI" state, the user shall initiate an emergency call by dialling the number 112 (for GSM 900 and 1 800 MSs), or 911 (for GSM 710, GSM 750, T_GSM 810, GSM 850, PCS 1 900 MS in USA and Canada), or 08 (for GSM 710, GSM 750, T_GSM 810, GSM 850, PCS 1 900 MS in Mexico). The MS shall send a CHANNEL REQUEST message with correct establishment cause ("emergency call").

2. When a user requests an emergency call establishment the mobile station will send a CM SERVICE REQUEST message to the network with a CM service type information element indicating emergency call establishment and the correct CKSN and TMSI. A mobile station which implements the “LCS” option shall also implement the “Controlled Early Classmark Sending” option. A mobile station which implements the “Controlled Early Classmark Sending” option shall indicate it in the classmark (ES IND bit).

3. After sending the CM SERVICE REQUEST message the MS shall send a CLASSMARK CHANGE message. The "Mobile Station Classmark 3" information element shall correctly specify the positioning methods supported by the MS.

4. After the CM SERVICE ACCEPT message is received form the network, the MS shall send an EMERGENCY SETUP message.

5. After receipt of a CONNECT ACKNOWLEDGE message during correct establishment of the emergency call the MS shall indicate that the TCH is through connected in both directions.

6. On receiving the RRLP MEASURE POSITION REQUEST message the MS tries to perform the requested location measurements. It sends the results in the RRLP MEASURE POSITION RESPONSE message.

70.7.4.4.2 Test Purpose

To verify when an emergency call is initiated by an MS that does not have a SIM fitted, the network instigates the LCS positioning procedure by sending RRLP (Measure Position Request) message and the mobile responds with RRLP (Measure Position Response) containing A-GPS measurement values.

70.7.4.4.3 Method of Test

Initial Conditions

System Simulator (SS):

Serving Cell: default parameters.

Satellite signals: default conditions.

Mobile Station (MS):

The MS is in MM-state “idle, no IMSI”, no SIM inserted.

SIM:

No SIM.

Specific PICS statements

PIXIT statements

Test Procedure

An Emergency Call is initiated by the MS, with no SIM inserted in the MS.

The emergency call is established with a late assignment.

After receiving the CONNECT ACKNOWLEDGE message from the MS, the SS sends an RR APPLICATION INFORMATION message containing an RRLP Measure Position Request on FACCH including assistance data.

Option 1: The MS then performs positioning measurements, and responds with an RR APPLICATION INFORMATION message containing an RRLP Measure Position Response.

Option 2: The MS may request additional assistance data by sending an RRLP Measure Position Response message containing a location error with IE LocErrorReason set to gpsAssDataMissing. If the MS requests additional assistance data that is available in the SS, then the SS provides the requested assistance data in zero, one or more RRLP Assistance Data delivery messages followed by an RRLP Measure Position Request message which may include further assistance data. If the MS requests additional assistance data and the entire requested assistance data is not available in the SS, then the SS repeats the RRLP Measure Position Request message without assistance data. The MS then performs positioning measurements, and responds with an RR APPLICATION INFORMATION message containing an RRLP Measure Position Response.

The call is cleared by the SS.

Maximum duration of the test

5 minutes.
