Content for TS 29.219 Word version: 18.0.0
1 Scope p. 6
The present document provides the stage 3 specification of the Sy reference point for the present release. The functional requirements and the stage 2 specifications of the Sy reference point are contained in TS 23.203. The Sy reference point lies between the Policy and Charging Rule Function (PCRF) and the Online Charging System (OCS). The internal OCS functionality for policy counter provision management pertaining to Sy is specified in TS 32.296.

3 Definitions and abbreviations p. 7
3.1 Definitions p. 7
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
policy counter:
A mechanism within the OCS to track spending applicable for a subscriber.
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.
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.
spending limit report:
a notification, containing the current policy counter status generated from the OCS to the PCRF via the Sy reference point.
