Subscriber Data Lookup Feature
The Friends and Family (FnF) feature sets a special OCS tariff code if a subscriber is making a call to a number in their FnF list. If the other party’s number is in the FnF list, Sentinel will send the configured FnF tariff code (=rating group) while performing charging to OCS. The subscriber for the call type will have been determined using the SS7 Subscriber Determination Feature. When the MSC triggers Sentinel, the FnF list is retrieved for the subscriber. The number to check in the FnF list for the subscriber is shown in the table below:
| Call type | Number to check against FnF list |
|---|---|
MOC |
CalledPartyBCDNumber |
MTC |
CallingPartyNumber |
MFC |
CalledPartyNumber |
NetworkInitiated(Callback) |
Leg #4 Address |
Emergency |
N/A |
MOSMS |
DestinationSubscriberNumber |
In all cases the normalized number will be used for the check.
It is expected that a subscriber’s Friends and Family list will be limited to a small number (such as 5). No logic will be implemented in the Profile/Database or Feature to enforce this limit. Any limit required by the operator will be enforced by the system provisioning the feature.
Any errors encountered during the execution of this feature, such as configuration errors or missing subscriber data, will have no effect on the call. No tariff will be set. The call will be allowed to proceed with other features.
