Cisco Cisco Packet Data Gateway (PDG)
With Release 19.2.1, this feature is available as fully qualified Deploy Quality.
Important
Feature Changes
The MME handles numerous subscriber calls from different eNodeBs in the network. In order to troubleshoot
any issues for a particular subscriber, the events that caused the issue is recorded. The events could be individual
procedures such as ATTACH, DETACH, TAU, Handovers and so on.

The Event Data Record is a proprietary feature of StarOS. In this feature, MME provides a debugging
framework to capture procedure level information for each subscriber. On the completion of a procedure
successfully or unsuccessfully, the MME generates a procedure summary. This summary provides details of
the events and issues, which is nearly comparable to real-time debugging.

Previous Behavior: Earlier, MME did not support Event Data Records (EDRs) for Event Logging.
New Behavior: From this release onwards, MME supports EDRs for events such as ATTACH, DETACH,
TAU and Handovers during Event Logging.
