The test included a phone call from one mobile to the other on the same cell,
in both cases this will force the BTS to disconnect the PDCH and reconnect
the TS as voice channels. While making the call, internet access was blocked
(expected) and after finishing the call internet access was available again.

>From the perspective of dynamic TS, I do not see any problems here.
