CSCua47367, CSCuh30602 - Enhance PGW to report exact failure resulting in

CC 73

Feature Changes

Additional Statistics for Cause Code 73: No Resource Available

In many scenarios, the P-GW responds to a Create Session Request by sending a Create Session Response with a Cause
Code 73 (NO RESOURCE AVAILABLE), thereby rejecting the session attempt. Cause Code 73 can be sent for
multiple reasons.

In this release, new bulk statistics have been introduced to further identify the exact sub-causes of error Cause Code 73.

The output of

show pgw-service statistics all verbose

has also been enhanced to show counters for Cause

Code 73 sub-causes.

Important:

These counters are cumulative of GGSN and P-GW. GGSN responds to a Create PDP Context

Request by sending a Create PDP Context Response with a Cause Code 73 (NO RESOURCE AVAILIABLE), similar
to P-GW.

Customer Impact: Enhanced statistics will help operators know the exact cause for rejection of the PDN setup at the
P-GW and thereby assist in identifying issues.
