Configuring ISR with Circuit Switched Fallback
The following commands are used to configure 3G paging cause for CSFB:
config
context <context_name>
iups-service <iups_service_name>
rnc id <rnc_id>
[default | no ] ranap paging-cause-ie mme-signalling < paging_cause_value >
end
Where:
The command
ranap paging-cause-ie mme-signalling < paging_cause_value >
is used to set the
Paging Cause IE value for paging from MME due to Circuit Switch Fallback (CSFB). Listed below are the
paging cause values which can be set:
paging cause values which can be set:
0 - Terminating conversational call
1 - Terminating streaming call
2 - Terminating interactive call
3 - Terminating background call
4 - Terminating low priority signaling
5 - Terminating high priority signaling
The default command resets the specific parameters value to default. In this case it is set to “5 - Terminating high
priority signaling”.
The no form of the command suppresses the Paging Cause IE so that it is not included in responses to Paging
Requests.
