Feature Changes

Previous Behavior: When the MME receives an update bearer request message during the handover process, it does not buffer update bearer request messages per subscriber at eGTP level.

New Behavior: MME buffers UBRs per subscriber at eGTP level. The Current Nb of UBRs buffered at mme app statistics is added under the show update-bearer-request-stats to display the current number of UBRs buffered at MME application.


Note

After a session manager restart, the session manager is not recovered. It is similar to Forced_UBResp_CC16_during_HO_3G_4G_TAU_TX and any other session counters. Hence, this counter is reset after a session manager restart.
