Direct Carrier Billing

Just wondering something... I am little confused when it comes to the term
'Direct Carrier Billing'. I though Direct Carrier Billing only implemented
by telecom companies such as At&t, Verizon wireless, T-mobile. However,
there exist third-party direct carrier billers such as BilltoMobie, Boku,
OpenMarket, Payfone, Zong. What does they do?
