There is no mandatory resource reservation scheme. The primary one 
specified so far is RSVP. nsis is another one under development. Groups 
like packetcable have specified their own QoS protocols.

Yes, 3gpp has its own mechanisms that are specific to 3gpp. As I 
understand they are built into the GPRS procedures, and reservation 
occurs only on the wireless link.
