The value of tmnxMobPdnApnPcrfDynamicPcc specifies whether to enable
the interaction with Policy and Charging Rules Function (PCRF)
for bearer creation. When dynamic-pcc is enabled,
Policy and Charging Control (PCC) rules are sent from
PCRF for dedicated bearer creation.
When the value of tmnxMobPdnApnPcrfDynamicPcc is 'inherit', the value
is inherited from the value of tmnxMobPdnPccDynamicState which
specifies if interaction with Policy and Charging Rules Function (PCRF)
is enabled for bearer creation or not at the gateway level.
