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.
