ASCI: Repeat notification after assigning MS to VGCS/VBS channel
The assinment is repeated because the calling subscriber may not receive
the notification on the DCCH, during handover process. After the
assignment is complete, the calling subscriber will receive notification.
This cannot be done automatically by the BTS, because the BTS has no
relation between the notifications and the channels.
The notification is required, so that the MS knows the channel to listen
to when leaving the uplink the first time. If no notification is
received, the MS will abort the call.
