Event Data Records (EDR)
The Event Data Records are responsible for definition, generation, and offloading of EDRs generated in the system (as a
result of occurrence of an event) to the external billing system. EDRs are basically used for content billing purposes,
wherein it is required that a different charging unit be employed for different types of content e.g. HTTP, SMTP, MMS,
etc. EDRs are a type of usage records that are configurable by the operator. EDRs are generated per flow subject to
available configuration.

Event Records
The Event reporting is a mechanism using which subscriber activities like session creation/deletion, bearer
creation/modification/update/deletion are reported to the external server (RTT server). The event report logs assist
network operators in maintaining and troubleshooting the network. The event records are stored as files in the HDD and
these files are later SFTPd to the external RTT server. To store the event records in the form of files, compress the event
record file using the Call Detail Records Module (CDRMOD) which provides support for collecting, storing, and
compressing the event records.
