For a given "consumer" having associations with multiple "provider" accounts that are possible targets for charging with respect to a chargeable event involving the consumer, only one or a relative handful of those provider accounts are likely to be actual candidates for charging. Correspondingly, a network node maintains provider account status information indicating whether a given provider account is a candidate for charging in a general sense and in a consumer-specific sense. Account information is retrieved only for the provider accounts indicated as actual candidates for charging, meaning that unnecessary data fetching, account locking, and charging reservation mechanisms are avoided for accounts that are not indicated as being actual candidates for charging with respect to the particular consumer and particular chargeable event. |
