70.14.2 MO-LR / Idle mode for Mobiles Supporting MS-Based GNSS / Assistance Data Request

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

70.14.2.1 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 self-location request by sending REGISTER message containing Facility IE LCS MO-LR with MOLR-TYPE set to assistance data.

3. The MS sends RRLP ASSISTANCE DATA ACK for each RRLP ASSISTANCE DATA component

4. The network shall returns an LCS result of the location procedure to the MS by sending a FACILITY message to the MS containing a LCS-MOLR return result component.

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

70.14.2.2 Test Purpose

To verify that a MS invokes a self-location request by sending the network a REGISTER message containing an LCS-MOLR REQ of type “Assistance data”. On receipt of each RRLP ASSISTANCE DATA from SS with the requested assistance data, MS shall send RRLP ASSISTANCE ACK for each component to SS. When the MS receives a FACILITY message containing a LCS-MOLR return result for the acknowledgement of completing assistance data delivery, it clears the transaction by sending a RELEASE COMPLETE message.

70.14.2.3 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 valid TMSI and CSKN.

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

Supported GNSS

1

MS supporting A-GLONASS only

2

MS supporting A-Galileo only

3

MS supporting A-GPS and Modernized GPS only

4

MS supporting A-GPS and A-GLONASS only

5

Reserved

6

9

MS supporting A-BDS only

10

MS supporting A-GPS and A-BDS only

The MS invokes call independent supplementary service through a CM SERVICE REQUEST.

The SS initiates authentication and ciphering. Then the MS invokes an MO-LR request, with MOLR- TYPE set to assistance data.

The SS sends a number of RRLP Assistance Data components and MS sends RRLP Assistance Data Ack for each component.

SS sends LCS-MOLR Return Result for acknowledgement of completion of assistance data delivery.

The MS terminates the dialogue by sending RELEASE COMPLETE message.

Maximum duration of the test

10 minutes.
