Nchf: Service-based interface exhibited by Charging Function.

Policy counter: A mechanism within the CHF to track spending applicable to a subscriber.

Policy counter identifier: A reference to a policy counter in the CHF 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 CHF to PCF. Specific labels are configured jointly in CHF and PCF.

Spending limit: A spending limit is the usage limit of a policy counter (e.g. monetary, volume, duration) that a subscriber is allowed to consume.
