Configuring Subscription Server Notification
UDC communicates with Subscription Servers to read and modify subscriber information. In order to give the correct subscriber information to PCRF, the UDC server needs to know the changes in subscriber LDAP attributes in the subscription server. The UDC server can get this information through notifications from the subscription server. In order to enable these notifications, configure UD interface and add services for each subscriber. The UDC server will receive notifications from the subscription server for changes in the attributes configured in the service.
Perform the following steps to configure UD interface with information about the subscription server to receive notifications:
In Policy Builder, navigate to Reference Data.
Under Plugin Configuration select U D Interface Configuration.
Enter the values in each field as described in the following table:
Navigate to Services to configure subscription service.
Add a Service Configuration named Subscription.
Add the attribute names.
While adding multiple attribute names separate each of them with commas.
If there are any changes to these attributes in the subscription server, UDC server will get a notification from the subscription server regarding that change.
