policy counter identifier: A reference to a policy counter in the OCS for a subscriber.

policy counter status: A label whose values are not standardized and that is associated with a policy counter’s value relative to the spending limit(s) (the number of possible policy counter status values for a policy counter is one greater than the number of thresholds associated with that policy counter, i.e policy counter status values describe the status around the thresholds). This is used to convey information relating to subscriber spending from OCS to PCRF. Specific labels are configured jointly in OCS and PCRF.
