Description (partial)

Symptom:
MME EMM message bulk statistics counters show discrepancy between MME and TAI schema.
This is observed when certain bulk statistics counters reported in MME  schema are compared with the sum of corresponding counters in the TAI schema.

The following bulk statistics were observed to have this discrepancy.
