CSCun86828 - CBR - MBR collision causing MME to delete dedicated bearer
Feature Changes
Modification to MBR Collision Procedure
When the S5/S8 interface detected a collision between already initiated Create Bearer Request and newly incoming
Modify Bearer Request, the Create Bearer Request was aborted at the P-GW. This resulted in any later Create Bearer
Response received from the MME/SGW to be rejected. As an impact SAEGW/PGW had one bearer less than the peer.
The software has been modified to resolve this problem, and has resulted in a behavior change:

Response received from the MME/SGW to be rejected. As an impact SAEGW/PGW had one bearer less than the peer.
The software has been modified to resolve this problem, and has resulted in a behavior change:
Previous Behavior: Create Bearer Request aborted on Modify Bearer Request. Create Bearer Response ignored in
Modify Bearer Pending state.
Modify Bearer Pending state.
New Behavior: Create Bearer Request is not aborted on Modify Bearer Request. Create Bearer Response will abort the
Modify Bearer Pending state, and re-transmit after Modify Bearer Response.
Modify Bearer Pending state, and re-transmit after Modify Bearer Response.
CSCuo90006 - Formulation of P-CSCF Address Output as part of show sub full
all
Feature Changes
Formulation of P-CSCF Address Output as Part of show sub full all
Simplified the P-CSCF Address Output as part of show sub full all output. The P-CSCF discovery mode specific
information is SR/GR recovered.
information is SR/GR recovered.
Previous Behavior: : Previously, the P-CSCF Address Output displayed the P-CSCF Address information separately
for S6b based FQDN and for Radius or configured scenarios. It also restricted the S6b mode to only display the IPv6
Address Information. IPv4 information was not being displayed. Also, the earlier output did not support persistence
across ICSR/Session Recovery for all the discovery modes.

across ICSR/Session Recovery for all the discovery modes.
New Behavior: : In the new output, a "Discovery Mode" field specifies the method of discovery followed by the actual
P-CSCF Address Information. Also, the new Output displays both IPv4 and IPv6 address information as per
applicability. The new Output remains persistent across ICSR/Session Recovery for all P-CSCF discovery modes.
