Abstract: An apparatus for deriving quality data includes a processor and memory storing executable computer code causing the apparatus to at least perform operations including receiving a consistency check from a network device indicating a summary count obtained during a time period. The summary count specifies a number of data items of a service utilized/provided, within a given time period, to one or more communication devices of an entity. The consistency check also includes a raw count, obtained during a time window the expiration of which is subsequent to the time period, indicating a number of data items of the service utilized/provided, within the given time period, to the communication devices. The computer program code may further cause the apparatus to determine whether a deviation between the summary count relative to the raw count is less than or equal to a threshold. Corresponding methods and computer program products are also provided.
