The Nchf_SpendingLimit
39、Control service enables the NF service consumer to retrieve policy counter status information per UE from the CHF by subscribing to spending limit reporting (i.e. notifications of policy counter status changes). If the spending limit reporting is no more required the Nchf_SpendingLimitControl servic
40、e enables the NF service consumer to unsubscribe from the reporting. 4.1.2 Service Architecture The Nchf_SpendingLimitControl service is provided by the CHF and consumed by the PCF, as shown in figure 4.1.2-1 for the SBI representation model and in figure 4.1.2-2 for the reference point representati

42、sentation 4.1.3 Network Functions 4.1.3.1 Charging Function (CHF) The Charging Function (CHF) is part of the Converged Charging System (CCS). The CHF provides the Nchf_SpendingLimitControl service and is specified in 3GPP TS 32.240 7. 4.1.3.2 NF Service Consumers The PCF is the known NF service cons
43、umer, as defined in 3GPP TS 23.502 3. The NF service consumer accesses policy counter status information relating to the subscriber spending from the CHF and uses the status of each relevant policy counter as input to its policy decision as required by the decision logic. 4.2 Service Operations 4.2.
44、1 Introduction The service operations defined for the Nchf_SpendingLimitControl service are shown in table 4.2.1-1. Table 4.2.1-1: Nchf_SpendingLimitControl Service Operations Service operation name Description Initiated by Nchf_SpendingLimitControl_Subscribe This service operation is used by an NF
45、service consumer to subscribe to notification of changes in the status of the policy counters available and retrieval of the status of the policy counters for which subscription is accepted. NF service consumer (PCF) Nchf_SpendingLimitControl_Unsubscribe This service operation is used by an NF servi
46、ce consumer to unsubscribe from notification of changes in the status of all policy counters. NF service consumer (PCF) Nchf_SpendingLimitControl_Notify This service operation is used by the CHF to notify the NF service consumers about the change of the status of the subscribed policy counters. Alte
47、rnatively, it can be used by the CHF to notify that the status for one or multiple subscribed policy counter will change in the future, indicating the time when this change shall be applied.

48、ntrol_Subscribe service operation 4.2.2.1 General The Nchf_SpendingLimitControl_Subscribe service operation is used by the NF service consumer to subscribe to notification of changes in the status of the policy counters available and to retrieve the status of the policy counters for which the subscr
49、iption is accepted. The following procedures are related to the subscribe service operation: - initial spending limit retrieval; and - intermediate spending limit report retrieval. 4.2.2.2 Initial spending limit retrieval Figure 4.2.2.2-1 shows the scenario where the NF service consumer sends a request to the CHF to retrieve the status of policy counters available at the CHF and to subscribe to spending limit reporting (see also 3GPP TS 23.502 3, figure 4.16.
