Description
In commercial mobil networks the operator disables the access to data services when a mobile device use a not allowed APN.
How can that be tested in the CMW and what has to be setup?
CMW LTE Attach Reject and APN Handling
Resolution
In commercial networks the Attach and theTraffic Area Update (TAU) will reject the data service with cause "EPS servicees not allowed" if a wrong APN is used.
So you have to configure this reject cause in the LTE cell configuration to simulate the same scenario.
You find the list of all posible Reject Causes in the LTE user manual.
Reject cause configrution in the LTE cell setup:
Important:
The APN setting for the Default Bearer that you find also in the LTE cell configuration is only used in case the device under test do come with a empty APN field.
So here you cannot configure the APN that will accepted and others will get rejected. You have to use the Attach and TAU Reject Cause settings instead.
