37、given in TR 21.905 1 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 1. policy counter: A mechanism within the OCS to track spending applicable for a subscriber. policy counter identifier: A reference to a po

38、licy counter in the OCS for a subscriber. policy counter status: A label whose values are not standardized and that is associated with a policy counters 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

39、 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

40、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. 3.2 Abbreviations For the purposes of t

The Sy reference point enabl

44、es transfer of policy counter status information relating to subscriber spending from OCS to PCRF and supports the following functions: - Request of policy counter status reporting from PCRF to OCS and subscribe to or unsubscribe from spending limit reports (i.e. notifications of policy counter stat

45、us changes). ETSI ETSI TS 129 219 V15.1.0 (2018-07)83GPP TS 29.219 version 15.1.0 Release 15- Notification of spending limit reports from OCS to PCRF. - Cancellation of spending limit reporting from PCRF to OCS. Since the Sy reference point resides between the PCRF and OCS in the HPLMN, roaming with

46、 home routed or visited access as well as non-roaming scenarios are supported in the same manner. The stage 2 level requirements for the Sy reference point are defined in 3GPP TS 23.203 2. Signalling flows related to the Sy interface are specified in 3GPP TS 29.213 8. Refer to Annex G of 3GPP TS 29.

47、213 8 for Diameter overload control procedures over the Sy interface. Refer to Annex J of 3GPP TS 29.213 8 for Diameter message priority mechanism procedures over the Sy interface. Refer to Annex K of 3GPP TS 29.213 8 for Diameter load control procedures over the Sy interface. 4.2 Sy Reference model

48、 The Sy reference point is defined between the PCRF and the OCS. The relationships between the involved functional entities are depicted in figure 4.2.1. The overall PCC architecture is depicted in clause 3a of 3GPP TS 29.213 8 OCSg3Syg3PCRFg3Figure 4.2.1: Sy reference model .Figure 4.2.2: Void 4.3

49、Subscriber Spending Limits Policy decisions based on spending limits is a function that allows the PCRF to make policy decisions based on the status of policy counters that are maintained in the OCS. The PCRF uses the policy counter statuses received from the OCS as input to its policy decisions, e.g. downgrade the QoS (e.g. APN-AMBR) or modify the PCC/QoS/ADC Rules. When the status of policy counters is first required to make a policy decision for a subscriber, the PCRF uses the Initial Spending Limit Rep
