70.14.8 MO-LR / Location Error

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

70.14.8.1 MO-LR / Location Error / Requested Method not supported

70.14.8.1.1 Conformance requirement:

The MS sends a DTAP LCS MOLR invoke to VMSC. If the MS is requesting its own location or that its own location be sent to another LCS client, this message carries LCS QoS information (e.g. accuracy, response time).

The MS invokes a MO-LR by sending a REGISTER message to network containing a LCS-MOLR invoke component with MO-LR TYPE set to LocationEstimate, LCS QoS value and other optional field if it is needed.

The MS sends a RRLP MEASURE POSITION RESPONSE to network containing a Location Error component with an error indication if the measurement is not possible.

The MS shall terminate the dialogue by sending a RELEASE COMPLETE message.

Test References:

3GPP TS 44.018 sub clauses 3.3.1.1 and 9.1.11.

3GPP TS 24.008 sub clauses 4.5.1.5, 5.2.1, 9.2.9 and 10.5.1.6, 10.5.1.7.

3GPP TS 44.031.

70.14.8.1.2 Test Purpose:

Verifies that a MS sends a correct positioning capability via control classmark sending. MS shall send back RRLP MEASURE POSITION RESPONSE message with Location Error component if the MS does not support the requested method. On receipt of second RRLP MEASURE POSITION REQUEST from SS to start the measurement, the MS shall send back RRLP MEASURE POSITION RESPONSE to SS after finishing the measurement.

70.14.8.1.3 Method of Test

Initial Conditions:

System Simulator:

Serving Cell: default parameters.

Satellite signals: default conditions.

Mobile Station:

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

Test Procedure:

This test case includes sub-test cases dependent on the GNSS supported by the MS. Each sub-test case is identified by a Sub-Test Case Number as defined below:

Sub-Test Case Number

1

MS supporting A-GLONASS only

A MOLR procedure as call independent supplementary services is initiated from the MS. The MS performs control early classmark sending to provide LCS positioning method capability. After sending the CIPHERING MODE COMPLETE message the MS sends a REGISTER message with Facility IE containing a component set to a DTAP LCS-MOLR Invoke.

The SS then instigates the particular message sequence by sending RRLP MEASURE POSITION REQUEST with a method type not supported by the mobile. (Type not supported to be GPS for sub-tests 1, 2 and 9,, Galileo for sub-tests 3, 4 and 10). The MS sends RRLP MEASURE POSITION RESPONSE to SS containing a Location Error component (Request Method not Supported) as the requested method is not supported.

The SS then sends a RR APPLICATION INFORMATION message containing a RRLP Positioning Capability Request message, and the MS responds with an RR APPLICATION INFORMATION message containing an RRLP Positioning Capability Response message indicating the GNSS(s) supported by the MS.

The SS repeats RRLP MEASURE POSITION REQUEST with correct message contents 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 SS returns location estimate to MS through LCS-MOLR Return Result. The MS terminates the dialogue by sending RELEASE COMPLETE message after receiving location estimate.

Maximum duration of the test:

5 minutes.

The MS invokes a MO-LR by sending a REGISTER message to network containing a LCS-MOLR invoke component with MO-LR TYPE set to LocationEstimate, LCS QoS value and other optional field if it is needed.

The MS sends a RRLP MEASURE POSITION RESPONSE to network containing a Location Error component with an error indication if the measurement is not possible.

The MS shall terminate the dialogue by sending a RELEASE COMPLETE message.

This test case includes sub-test cases dependent on the GNSS supported by the MS. Each sub-test case is identified by a Sub-Test Case Number as defined below:

The A-GNSS assistance data stored in the MS is reset.

A MOLR procedure as call independent supplementary services is initiated from the MS. The MS performs control early classmark sending to provide LCS positioning method capability. After sending the CIPHERING MODE COMPLETE message the MS sends a REGISTER message with Facility IE containing a component set to a DTAP LCS-MOLR Invoke.

On receiving the RR APPLICATION INFORMATION message containing a RRLP Positioning Capability Request message, the MS responds with an RR APPLICATION INFORMATION message containing an RRLP Positioning Capability Response message indicating the GNSS(s) supported by the MS.

The SS then instigates the particular message sequence by sending RRLP MEASURE POSITION REQUEST without GNSS assistance data (GPS or GANSS according to the receiver capabilities).

The MS requests additional assistance data by sending an RRLP Measure Position Response message containing a location error with IE LocErrorReason set to gpsAssDataMissing or ganssAssDataMissing for sub-test cases 3, 4 and 10 and set to ganssAssDataMissing for sub-test cases 1, 2 and 9. The SS provides the requested assistance data that is available in the SS in zero, one or more RRLP Assistance Data delivery messages followed by an RRLP Measure Position Request message which may include further assistance data.

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

The SS returns location estimate to MS through LCS-MOLR Return Result. The MS terminates the dialogue by sending RELEASE COMPLETE message after receiving location estimate.

Maximum duration of the test:
