By default the GGSN accepts the CC from the SGSN for all three scenarios.
If the GGSN is to use its own CC for any of these scenarios, then each scenario requires the
specification of behavior bits and a profile index to use.
NOTE: The profile index parameters are configured as part of the GGSN service.
