7200 has no DCCA support for prepaid charging solutions. Service-aware GGSN (real-time credit-control for prepaid users, as well as service-aware billing for postpaid and prepaid users) functionality is supported on the Catalyst 6500/Cisco 7600 platform only.
Unfortunately I'm not aware of any other solution for c7200. I'll try to find out, but I do not promise anything. I know that there are some other solution but on other platforms (Nokia, Siemens) but those are out of discussion here and anyway I'm not an expert in those solutions.
