Feature Changes
LAPI in SGW-CDRs
As part of MTC feature support in S-GW, Low Access Priority Indicator (LAPI) attribute is supported in SGW-CDR.
This field indicates if the PDN connection has a low priority, i.e. for Machine Type Communication. SGW-CDR for
custom24 and custom35 GTPP dictionaries have information about LAPI if the CLI command “

Feature Changes
Changes to HDD Directory Structure
The directory name creation logic for GTPP HDD is changed. Previously, vpn-id is used as part of the directory name.
This logic is changed to include the GTPP accounting context-name.
This logic is changed to include the GTPP accounting context-name.
Previous Behavior: The CDRs were placed in the following directory paths for local mode:
RAM-disk: /records/cdr/<gtpp-group-name><vpn-id>
HDD: /hd-raid/data/records/cdr/<gtpp-group-name><vpn-id>
For GTPP streaming mode, the directory structure was as follows:
RAM-disk: /records/cdr/hdd_sec_stor_<gtpp-group-name><vpn-id>
