different generation of accounting records occur based on the "type" of mode. To enable the different
generation of accounting records, the trigger for preservation mode must be configured for RADIUS or GTPP
command for that accounting protocol. If that trigger is not configured, there will be no change in the
generation of accounting records.

Removes the private extensions from record which are from GTP-C messages received from the SGSN.
Usage
Use this command to configure the private extensions to record from the GTP-C messages received from
SGSN. It also configures the customer specific features; i.e. preservation mode for GGSN service.
Overcharging protection for LORC is a solution which provides the ability to configure mobile carriers to
maximize their network solutions and balancing the requirements to accurately bill their customer.
Consider scenario where a mobile is streaming or downloading very large files from external sources and the
mobile goes out of radio coverage. If this download is happening on Background/Interactive traffic class then
the GGSN is unaware of such loss of connectivity as SGSN does not perform the Update PDP Context
procedure to set QoS to 0kbps (this is done when traffic class is either Streaming or Conversational only).
The GGSN continues to forward the downlink packets to SGSN. In the loss of radio coverage, the SGSN will
do paging request and find out that the mobile is not responding; SGSN will then drops the packets. In such
cases, the G-CDR will have increased counts but S-CDR will not. This means that when operators charge the
subscribers based on G-CDR the subscribers may be overcharged. This feature is implemented to avoid the
overcharging in such cases.
This implementation is based on Cisco-specific private extension to GTP messages and/or any co-relation of
G-CDRs and S-CDRs. It also does not modify any RANAP messages.
