open-cgf 0.10 (Default branch) |
|
|
open-cgf provides a 3GPP-compliant charging gateway function (CGF) as a sink for SGSN, GGSN, and other streamed CDRs on the 3GPP Ga/Gz interface using GTP' (GTP prime). Refer to 3GPP 32.295. These are common packet-switched data elements of GSM/UMTS mobile telephone networks. It aims to supply a telco-grade solution to this common, albeit very specialized, need. It does not decode the ASN.1 CDRs, but simply and reliably writes them to disk for later processing.

Changes:
The CDR logging was rewritten to reflect the
standards and other implementations. This may have
created some new bugs. Some "reliability" was
added to the sending of CGF-initiated messages,
although there are no consequences to non-response
yet. Backoff is exponential (a la TCP).
