Billing and charging sit at the commercial core of every communications service provider (CSP). Rating engines price each call, session and data event; charging systems apply those prices in real time; and billing platforms turn the result into an invoice a customer can read and pay. OSS News Review has covered this market since the early 2000s, from the era of standalone postpaid billing to today’s cloud-native convergent charging.
What This Coverage Includes
This hub collects our reporting on the systems that monetize network usage. That includes convergent billing (a single platform billing prepaid, postpaid, fixed and mobile services together), online charging systems (OCS), which authorize and deduct balances while a session is in progress, and interconnect and wholesale settlement, where carriers reconcile the traffic they exchange with one another.
It also includes policy control. A policy and charging rules function (PCRF), or its 5G successor, the policy control function (PCF), decides how a subscriber’s traffic is treated based on plan, balance and network conditions. Policy and charging are now designed together, so we report on them together.
Why It Matters to Operators
Billing is where product strategy meets operational reality. A new bundle, a usage-based enterprise offer or a 5G network slice cannot launch faster than the billing stack can rate it. Vendor selections, platform migrations and go-live announcements in this category are therefore among the most consequential decisions a CSP makes, and they are the stories we track most closely.
