A.8.5A CSG Proximity Indication Testing Case for UTRAN FDD – FDD Inter frequency
25.1333GPPRelease 17Requirements for support of radio resource management (FDD)TS
Note : The test case in this section forms the basis for a signalling test for CSG proximity detection.
A.8.5A.1 Test Purpose and Environment
The purpose of this test is to verify the UE has implemented properly the feature for indicating that the UE is entering or leaving the proximity of one or more CSG member cells based on proximity detection with an autonomous search function as defined by the requirements in Section 6.7.
The test case consists of three successive segments: Test Preparation, Negative Test, and Positive Test. The test scenario comprises of three UTRAN FDD cells on different carriers. Cell 1 represents the serving cell in the proximity of the CSG cell, Cell 2 the CSG cell and Cell 3 the serving cell not in the proximity of the CSG cell. The description of the test procedure is shown in Table A.8.5A-1. The general test parameters and cell specific test parameters are presented in Table A.8.5A-2 and Table A.8.5A-3 respectively.

Comment |
Test Preparation |
||
Initial Condition |
Cell 1 is active |
Clean up the UE memory to be free from previously stored cell information for proximity detection. Turn on the UE and allow sufficient time for the UE to reselect to Cell 1. |
Time duration T1 |
Cell 1 and Cell 2 are active |
Turn on Cell 2 at the start of T1. Perform manual CSG selection towards Cell 2. The UE is expected to store necessary information for later proximity detection. |
End condition |
Turn off the UE. Turn off Cell 1 and Cell 2. |
|
Negative Test |
||
Initial Condition |
Cell 3 is active |
Turn on Cell 3. Turn on the UE and set up the UE in connected mode with Cell 3 |
Time duration T2 |
Cell 3 is active |
Configure the UE with proximity indication control by sending the Measurement Control message to enable CSG Proximity detection at the start of T2. The UE is not expected to report “entering” proximity in the negative test. |
End condition |
Turn off the UE. Turn off Cell 3. |
|
Positive Test |
||
Initial Condition |
Cell 1 is active |
Turn on Cell 1. Turn on the UE and set up the UE in connected mode with Cell 1 |
Time duration T3 |
Cell 1 and Cell 2 are active |
Turn on Cell 2 at the start of T3. Configure the UE with proximity indication control by sending the Measurement Control message to enable CSG Proximity at the start of T3. The UE is expected to report “entering” proximity before end of T3. |
Time duration T4 |
Cell 1 is active and Cell 3 are active |
Turn off Cell 2 and turn on Cell 3 at the start of T4. Hand the UE overNote 1from Cell 1 to Cell 3 . (Note: The UE may report “leaving” proximity in T4. In this case, there is no need to proceed to the next step.). |
Time duration T5 |
Cell 3 are active |
Turn off Cell 1 at the start of T5. The procedures in T4 and T5 together simulate the situation that UE leaves the proximity of the CSG cell. The UE is expected to report “leaving” proximity before end of T5.. |
End condition |
Turn off the UE. Turn off Cell 1 and Cell 3. |
|
Note 1: The handover from Cell 1 to Cell 3 must preserve the proximity configuration (i.e. must involve neither SR-VCC handover, nor SRNS relocation, as described in [16]) |

Time duration T1 |
s |
[10] |
Defined to give enough time for the UE to complete the registration to Cell 2. |
|
Time duration T2 |
s |
[360] |
Defined to be longer enough to see whether the UE will report enter “proximity” indication. |
|
Time duration T3 Note 1 |
s |
[<=360] |
The time duration for a UE to report enters “proximity” when the UE is near a CSG cell. |
|
Time duration T4 Note 1 |
s |
[<=360] |
The time duration for a UE to be handed over to Cell 3. |
|
Time duration T5 Note 1 |
s |
[<=360] |
The time duration for a UE to report leaving “proximity” when the UE is no longer near a CSG cell. |
|
Note 1: The maximum allowed time duration for the UE to decide either entering or leaving “proximity” is 360s. To reduce test time, T3 may end once UE reports entering “proximity”, T4 may end once the UE is handed over to Cell 3 and T5 may end once UE reports leaving “proximity”. Note 2: The test case assumes an environment where CSG proximity detection results not being impact by non-3GPP signals, such as GPS and WiFi. When the test case is being executed, the UE may ignore any radio signals which are not provided by the test setup which it would otherwise use in proximity estimation. |
