70.14.6 MO-LR / Dedicated Mode for Mobiles Supporting MS-Based GNSS / Location Estimate request

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

70.14.6.1 Conformance requirements:

The following requirements apply for this test:

  1. The MS sends CM SERVICE REQUEST to network for call independent supplementary service.
  2. The MS invokes a MO-LR by sending a REGISTER message to the network containing a LCS-MOLR invoke component.
  3. On receiving the POSITIONING CAPABILITY REQUEST message the MS responds with a POSITIONING CAPABILITY RESPONSE message indicating the positioning methods supported by the MS.
  4. On receiving an RRLP MEASURE POSITION REQUEST message, the MS tries to perform the requested location measurements, and possibly calculates it own position. When the MS has location measurements, location estimate, or an error indication (measurements/location estimation not possible), it sends the results in the Measure Position Response component to the SMLC.
  5. The network shall pass the result of the location procedure to the MS by sending a FACILITY message to the MS containing a LCS-MOLR return result component.
  6. After the last location request operation the MS shall terminate the dialogue by sending a RELEASE COMPLETE message.

70.14.6.2 Test Purpose

To verify that the MS invokes a self-location request by sending the network a REGISTER message containing an MO-LR Request of type “locationEstimate” on an already established speech call related SACCH. When the MS receives a FACILITY message containing a MO-LR return result carrying the requested location estimate, it clears the transaction by sending a RELEASE COMPLETE message.

70.14.6.3 Method of Test

Initial Conditions

System Simulator:

Serving cell: default parameters.

Satellite signals: default conditions.

Mobile Station:

The MS has valid TMSI and CKSN.

The MS is brought into state U10 by using table 26.8.1.2/3.

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:

3

MS supporting A-GPS and Modernized GPS only

The MS invokes call independent supplementary service on an existing SACCH channel. After receiving a CM SERVICE ACCEPT message, the MS invokes a self location request by sending a REGISTER message containing an MO-LR request of type “locationEstimate”.

The SS sends an RR APPLICATION INFORMATION messages 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 orders positioning measurement by sending RR APPLICATION INFORMATION messages containing RRLP Assistance Data messages followed by an RRLP Measure Position Request including further 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 or ganssAssDataMissing. 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 responds with a FACILITY message containing an MO-LR result. When the MS receives the FACILITY message, it clears the transaction by sending a RELEASE COMPLETE message.

Maximum duration of the test:

5 minutes.
