In this article, we'll cover how to configure your Plan Setting to set up a voice call in Link Master.

Launching Your Plan Settings

Once you've started Link Master, you can launch Plan Settings using its icon located in the primary navigation bar.

Alternatively, you can do this by going to Control > Plan Setting. 

Here's what the Plan Setting window looks like (yours might vary a bit from the screen shown below).

You'll see at the top of the Plan Setting window that there are a few different tabs. For the purposes of this tutorial, we'll just cover how to set up a Voice Call.

Setting Up a Voice Call

There are several steps required to set up a voice call. We'll walk through these settings based on section.

Scenario/Plan Mode

There are two modes available for the call plan. For this tutorial, we'll choose Plan to configure a simple voice call.

Basic

In the Basic area of the Voice Call page, you'll see a variety of settings you can configure.

Call Type: the type of call you'd like to make for your test. Set this as Pair call with other CH (primarily used for mobile-to-mobile MOS scores.  Allows for coordination between two phones that are connected to LML).

Call Pattern: whether you want the calls to be originating, terminating, or some combination of both (for example, you might provide OOTTOO, which is two original calls, followed by two terminating calls and two more originating calls). In this instance, we'll just set this to O, for one outgoing call.

Dial Number: the number to be dialed. You can use the MIN dropdown to change the number shown in this field to reflect the numbers you provided in the Channels area of your Plan Settings screen. 

Service Option: Also known as, "how do you want the software to control the dialing operation of the mobile phone?" Set this to 103. Bluetooth - Voice with Dial Number

Target Service: allows LML to look for the call processing in the correct location. Set as VoLTE.

Detect UE-UE Conversation: most of the time, you'll have this option to detect checked

Pair channel plan for <Sync. call with other UE>

If you're setting up a paired call, you'll configure the details in this section. You'll want to start with a checkbox in CH1 and none next to CH2.

Pair channel: The channel with which you want paired with the number you're using (in this instance, it should be CH2).

Service option: This setting is identical to the one shown in the Basic section above, but in this case, you'll be setting it for the paired phone number

Service type: This setting is identical to the one shown in the Basic section above, but in this case, you'll be setting it for the paired phone number

Generally speaking, the Service option and Service type in both sections should be identical.

Call count & time

At this time, you'll configure your calls by setting the following:

Call count: how many calls you want run during the test. Set to 50.

Setup timeout (sec): how much time must elapse before the call is considered to be blocked. Set to 20.

Traffic time (sec): how long you want the call to be active. Set to 65.

Idle time (sec): how much time should elapse before the end of one call and the beginning of the next. Set to 15.

QoE Measurement

Check the box next to Voice Quality to run the voice quality test. Once the box is checked, you can go into the Config screen.

Measurement Count Control

Secure measurement count: the maximum number of measurements being transmitted - if unchecked, MOS readings for the entire duration of the test are returned. Set this to 4, which will return two sets of clips, with each direction lasting 7 seconds each.

Measurement Method

Standard: the standard to run for your test. Set as P.863 (POLQA - NB)

Rx Speech and Tx Speech: the reference speech to use. Set both to AmEnglish NB.

Wave File Save Condition

In this section, you'll set the parameters by which you want the wave file saved. You can set the lower bound of or the average MOS required, as well as whether the call record is saved at all. For this tutorial, the values are:

• Save speech if MOS is lower than: set as 3.00
• Save call of Complete call if average MOS is lower than: set as 3.2
• Save Call Record: checked

BQ & CBQ Condition

BQ & CBQ (Bad Quality and Continuous Bad Quality) parameters are set to determine what actually constitutes a bad quality and what constitutes a continuous bad quality call. Here are the parameters to get set up:

• Check BQ & CBQ: checked
• BQ MOS threshold (<): set to 2.20
• CBQ MOS threshold (>): set to 1.90
• CBQ count (>=): set to 2

Misc

In this section, set the following for the length of your intervals and your wait time:

Interval: the best option is 7 sec

Wait time (msec): leave at 2000

Saving Your Changes

Once you've made the appropriate configuration changes for your Voice Quality Measurement test, be sure to check the Copy to all box so that your settings get applied to all of your channels.

Click Ok to proceed.

Saving Your Plan Settings

Once you have made all of your desired changes to the Plan Setting tab, click OK to save and proceed. You're now ready to begin running your tests.

Run Your Tests

Click on All Channel in the left-hand navigation pane.

Then click on Voice Call Monitor. 

You'll see two windows pop open that provides you with some information about your call.

Then, go to Information > Voice Quality Monitor to bring up your MOS scores, along with areas for your test results. 

Start your measurement.
