Active. Active counts are incremented on the Standby S-GW but in bulk statistics the S-GW sends active counters as 0
(zero), while the setup and release counts may be non-zero. Bulk statistics setup and release counters will reflect counts
when this S-GW was last in the Active state.

Customer Impact: Previously, for a single call the customer would receive double the actual counter total Active and
Standby statistics were added together. The counters now are incremented on the currently Active S-GW only, so the
counter total is correct.
