IV. Testing Mode

4.1 Idle Mode

In idle mode, the mobile station is standby and not making any call. You can

just click record button to start recording idle mode. Use Idle Mode to test

sectorization and cross feeder on the night of cut over.

4.2 Idle Lock and Idle Prevent

When the mobile station is in idle mode, it can be locked to one channel or to

a set of channels. This inhibits all reselections to other channels, regardless of the

signal strength and quality of neighboring cells. The inverted operation is also

possible, namely to prevent reselection to a specified channel set.

Click

on the toolbar, and select which channel you want to lock

To reset the lock on channel function, simply click

on the toolbar.

There is another way to lock on channel, by using Equipment Properties :

4.4 Force Handover and Prevent Handover

When the mobile station is in dedicated mode, you can manipulate handovers. Specifically, you can do one of the following:

Prevent handover to specified channels. The mobile then reports no signal strength for these channels.

Force handover to a specified channel, or restrict handovers to a chosen channel set. The mobile then reports a RxLev of 63 for any such cell, 10 for the serving cell and no RxLev for other neighboring cells.

Click

(Equipment Properties) on the toolbar

To Force handover, simply select “Target HO” Function, and choose target channels.

To Prevent handover, simply select “Prevent HO” Function, and choose target channels.
