P-GW Changes in Release 16
▀ P-GW Enhancements for 16.0
▄ Release Change Reference, StarOS Release 16

Previous Behavior: Previously, active and setup counters were incremented on standby box for P-GW/GGSN service
statistics while they should be incremented only on active box. Similarly, active setup and release counters were
incremented on standby box for P-GW/GGSN APN statistics and these incremented counters were sent in bulk
statistics.

statistics.
New Behavior: Setup and release counters are no longer incremented on standby box for P-GW/GGSN service
statistics and P-GW/GGSN APN statistics; these will be incremented only when the box becomes active. Active counts
are incremented on standby box, but in bulk statistics active counters are sent as 0 (zero), while setup and release count
may be non zero.

may be non zero.
For bulk statistics, setup and release counters will reflect counts when this box was last in active state.
Customer Impact: Earlier, for single call customer was counted double if they sum up both active and standby
statistics. Now, counters are incremented on only one box, which is current active so they will get correct counters
value.

This change is applicable only for P-GW and GGSN service.

CSCul61774 - SM-IPNE auto-association for Gn/Gp setup
Feature Changes
IPNE Auto Association for Gn/Gp Setup
Previous Behavior: IPNE service was independently associated with GGSN and P-GW.
New Behavior: For Gn/Gp setup, whenever IPNE is associated with GGSN, it will be auto-associated with P-GW. In
the same way, if associating with P-GW, it will auto-associate with GGSN.
the same way, if associating with P-GW, it will auto-associate with GGSN.
Auto-disassociation will take place similarly. The disassociation between GGSN and P-GW services won't have any
effect over IPNE's association with GGSN or P-GW service.
effect over IPNE's association with GGSN or P-GW service.
Customer Impact: For Gn/Gp setup, if IPNE is associated with GGSN, then 4G calls will also get bound with IPNE. If
associated with P-GW, IPNE will also support the 3G calls.
associated with P-GW, IPNE will also support the 3G calls.
