1. A method, comprising:
registering multiple Charging Function (CHF) instances, where the registering associates each CHF instance, of the multiple CHF instances, with one of multiple CHF group identifiers;
storing, by a first network device, CHF selection data that includes a CHF group identifier (CHF-Group-ID) associated with a subscriber;
obtaining, by a second network device that functions as a CHF consumer, the CHF-Group-ID from the first network device; and
sending, by the second network device and based on the obtaining, charging data to a CHF instance associated with the CHF-Group-ID,
wherein subscriber data stored in a CHF instance associated with the CHF-Group-ID is not replicated to another CHF instance with a different CHF group identifier of the multiple CHF group identifiers.
