41、 Overview The Sy reference point is located between the Policy and Charging Rules Function (PCRF) and the Online Charging System (OCS). The Sy reference point enables transfer of policy counter status information relating to subscriber spending from OCS to PCRF and supports the following functions:

42、- 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 status changes). ETSI ETSI TS 129 219 V13.4.0 (2017-01)83GPP TS 29.219 version 13.4.0 Release 13- Notification of spending limit reports fro

43、m 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 home routed or visited access as well as non-roaming scenarios are supported in the same manner. The stage 2 level requirements for the

44、 Sy reference point are defined in TS 23.203 2. Signalling flows related to the Sy interface are specified in TS 29.213 8. Refer to Annex G of TS 29.213 8 for Diameter overload control procedures over the Sy interface. Refer to Annex J of TS 29.213 8 for Diameter message priority mechanism procedure

45、s over the Sy interface. 4.2 Sy Reference model 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

46、.1: Sy reference model .Figure 4.2.2: Void 4.3 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 fr

47、om 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 Report Request procedure. The PCRF may reques

48、t specific or all policy counter statuses to be reported by the OCS for the user. The OCS provides the status to the PCRF of the requested policy counters, and will notify the PCRF of any changes in the status of those policy counters. Optionally, the OCS can provide one or more pending statuses for

49、 a requested policy counter with the times that have to be applied. The pending status of a policy counter shall autonomously become the current status of a policy counter at the PCRF when the indicated corresponding time is reached. Subsequently, the provided information for pending statuses of a policy counter shall overwrite the previously received information. NOTE 1: The mechanism for provisioning the policy counters in the OCS is out of scope of this document. NOTE 2: A policy counter in the OCS can repre
