This can be configured within the Call Control Profile Configuration Mode as well as in the MME Service

the mme-service, the cause configured for the call-control-profile will be signalled to the UE.

the mme-service, the cause configured for the call-control-profile will be signalled to the UE.
The default cause-code mapping for “GW not reachable” for Attach procedures is still ESM-FAILURE, but for TAU
procedures the default is now set to NO-EPS-BEARER-CONTEXT-ACTIVATED.

Command Changes
local-cause-code-mapping gw-unreachable
This command includes new optional keywords to configure the local cause code mapping separately for both Attach
and TAU procedures. This enables an operator to configure the same cause-code for both Attach and TAU procedures,
or separate cause-codes for Attach and TAU.
and TAU procedures. This enables an operator to configure the same cause-code for both Attach and TAU procedures,
or separate cause-codes for Attach and TAU.
A new cause code keyword,
no-bearers-active
, is also now available for the GW unreachable error condition. This
configures the MME to return the NO-EPS-BEARER-CONTEXT-ACTIVATED cause code in the reject message. This
cause code can only be configured for TAU procedures, as it is not valid for Attach procedures.
