This feature determines Mobile Country Code (MCC), Mobile Network Code (MNC), and ISO Country Code values for the subscriber.
This data can then be included in Credit Control Requests (CCR)s by mappers and Call Detail Records (CDR)s by the AVP CDR feature.
This feature is an extension of the Sentinel SIP Extract Network Info feature. It implements the same behaviour as that feature for SIP message triggers, but also includes behaviour for dealing with TCAP message triggers.

Session State Inputs and Outputs
This feature uses all of the session state fields of its parent feature. For a list of these, see that features documentation.
In addition, it uses the following fields:
Statistics
IPSMGWExtractNetworkInfo statistics are tracked by the sentinel.ipsmgw SBB
and can be found under the following parameter set in REM:
SLEE-Usage → sentinel.ipsmgw service → sentinel.ipsmgw SBB → feature → IPSMGWExtractNetworkInfo
or with rhino-stats:
"SLEE-Usage.Services.ServiceID[name=sentinel.ipsmgw,vendor=OpenCloud,version=3.1.0].SbbID[name=sentinel.ipsmgw,vendor=OpenCloud,version=3.1.0].feature.IPSMGWExtractNetworkInfo"

Configuration
This feature uses the same configuration profiles as the Extract Network Info feature. See:
Provisioning interfaces
The feature is provisioned using the Sentinel IP-SM-GW feature REST API.
Behaviour
SIP Request Triggers
When triggered by a SIP request, this feature will execute its parent feature’s behaviour as described here: Extract Network Info - Behaviour
TCAP Message Triggers
The IPSMGWExtractNetworkInfo feature extracts MCCs and MNCs from:
-
The access and visited network info headers found in registration records. This requires the Registration Lookup From Cassandra feature to run before this feature.
-
The
IMSI. This requires the Fetch IMSI feature to run before this feature.
The resulting information is recorded in session state for use by the AVP CDR Feature feature when writing a CDR, as well as the charging features when forming charging requests.
The following OpenCloud extension AVPs are used to communicate MCC and MNC information in CCRs and CDRs:
-
OC-ACCESS-NETWORK-MCC-MNC -
OC-VISITED-NETWORK-MCC-MNC -
OC-IMSI-NETWORK-MCC-MNC -
3GPP-IMSI-NETWORK-MCC-MNC
