Subscriber decides, and then the network allocates the resources. Nobody else decides whether the customer should do data or voice.
The one who allocates the resources is the BSC for voice and the PCU (or MFS) for the packet data.
The BTS contains no intelligence, usually (except motorola one, AFAIK), everything is centralized in the BSC/PCU.
