Description: G-CDRs contain information for part, or the entire duration, of a PDP context. The G-CDR includes information such as the subscriber (MSISDN, IMSI), APN used, QoS applied, SGSN ID (as the mobile access location), a time stamp and duration, data volume recorded separately for the upstream and downstream direction, and volume thresholds for intermediate CDR generation and tariff time switches.

In addition to all of the above, additionally, enhanced G-CDRs contain a service-record part that contains the usage data of each service flow used by a PDP session (specified by category ID). For example, the upstream and downstream volume and duration is recorded per service flow.

By default this feature is not enabled.

The number specified is the maximum number of service records a G-CDR can contain before the G-CDR is closed and a partial G-CDR is opened.
