The present document studies the CHF discovery and selection in order to support the discovery of a CHF by the NF consumers like SMF, AMF, SMSF and PCF based on information about network segments that the CHF belongs to.
The following are studied:
- possible charging scenarios and requirements which makes use of CHF Segmentation.
- potential charging solutions which make use of CHF Segmentation.

4 Overview p. 9
The current NRF Based Discovery can use the SUPI, GPSI PLMN and CHF Group ID for CHF Discovery and Selection according to clause 6.1.6.2.32 of TS 29.510, and clause 6.1 of TS 32.290. The CHF(s) can be selected taking in account the business model in use by a Customer, for instance its possible to group the CHF instance(s) for enterprises customers and another one for non-enterprise customers, and taking in account the deployment model in place (e.g. central or local/edge).
The present document aims to study on how to enhance HF Discovery and selection by the NF Consumers like SMF, AMF, SMSF, PCF and other NFs, as specified in various 3GPP Charging Specifications.
