Lowercase Displayed for Received APN Names
CSCuy40169 - MME ignores APN config from subscription and uses wildcard APN config
Feature Changes
Previous Behavior: In earlier releases, the output generated by the "show mme-service db record imsi
<imsi-value>" command displayed the letters in the APN names in the case (uppercase or lowercase) in which
they were received from the HSS.

they were received from the HSS.
New Behavior: The output generated by the "show mme-service db record imsi <imsi-value>" command
now displays as all lowercase letters for the received APN names; no matter the case in which they were
received from either the HSS or the UE.

Disabling MSC Fallback on Failure Based on SRVCC Cause
CSCuy44854 - MME wrongly tries to establish call with other MSC during SRVCC failure
Feature Changes
Old Behavior:
If a voice call can be handed over to one of multiple MSC IP addresses during SRVCC handover and if the
PS-CS Response from the first MSC returns with a negative cause, then the next MSC is tried.
PS-CS Response from the first MSC returns with a negative cause, then the next MSC is tried.
New Behavior:
If a voice call can be handed over to one of multiple MSC IP addresses during SRVCC handover and if the
PS-CS Response from the first MSC returns with a negative cause and that cause has been included in the
MME's Call-Control Profile configuration with the new msc-fallback-disable command, then the MME fails
the SRVCC HO and does not try the next available MSC.
PS-CS Response from the first MSC returns with a negative cause and that cause has been included in the
MME's Call-Control Profile configuration with the new msc-fallback-disable command, then the MME fails
the SRVCC HO and does not try the next available MSC.
The new command is explained in the Command Changes section below. If this command is not used to define
SRVCC causes, then the MME will use default behavior to select the next MSC to retry PS-CS Request.
SRVCC causes, then the MME will use default behavior to select the next MSC to retry PS-CS Request.
Command Changes
A new command, msc-fallback-disable, enables the operator to define all SRVCC causes for which the MME
does not try sending PS-CS Request to a next available MSC during an SRVCC handover if the MME received
one of the configured SRVCC causes in the PS-CS Response from the first MSC.
