Testing Idle Timeslot

This describes how to test the idle timeslots in the network.

Prerequisites

The LMT runs normally.
The communication between the LMT and the BSC is normal.
The communication between the BSC and the BTS is normal.

Context

In the network optimization process, you need to manually set the network to maximum interference mode to obtain the maximum interference of the entire network. To achieve this maximum interference mode, you need to set all idle timeslots in a specific area to send idle Burst (Dummy Burst). Before the test, set the test time to 1 to 24 hours. The test can be stopped automatically or manually.

Procedure

Through GUI
1. Choose BTS Maintenance > Maintain TRX > Test Idle Timeslot.
2. Set Location and Duration, and then click Start. The results are displayed in the Test Result area, as shown in Figure 1.

  NOTE:
  
  After the idle timeslot test is enabled, all the timeslots in non-communication status will send the idle Burst until when the preset time is up. The purpose of sending the idle Burst is to perform the TCH TRX Cabinet Top Power Test or Intermodulation Interference Rectification. The TRX configured with the TCH does not send power in non-communication status. In this case, to obtain the cabinet top power value, you must perform the Idle Timeslot Test. The Intermodulation Interference Test also requires the Idle Timeslot Test to analyze the traffic statistics of the interference band of channel before and after the Idle Timeslot Test is enabled.
3. Click Stop.
Through MML
1. You can run the following commands on the LMT to test idle timeslots.
  - Run the STR TRXBURSTTST command to start testing idle timeslots.
  - Run the STP TRXBURSTTST command to stop testing idle timeslots.
