A usage subscription defines the relationship between a service point and a usage recipient, such as a service provider or a billing system1. A usage subscription must exist before usage transactions can be calculated for a specific service point2. The usage recipient is configured in the usage subscription type, which is a template for creating usage subscriptions3. The usage subscription type specifies the default usage recipient, the usage rule type, the usage subscription status, and other attributes for the usage subscriptions of that type3. References:
