Section: Annex G (informative): Business to Business (B2B) charging architecture and principles G.2.1 General
Content: In the B2B scenario, the charging architecture may involve two modes of interaction: - Business CHF interaction: the NF (CTF) collects and reports the charging information per business, alternatively it collects and reports the charging information per consumer but for business charging purposes, to the business CHF (i.e. B-CHF). - Business CHF via consumer CHF interaction: the NF (CTF) collects and reports the charging information per consumer to a consumer CHF (i.e. C-CHF), and the C-CHF reports the charging information per business to the business CHF (i.e. B-CHF).
