Abstract: A billing center for a mobile communications system is provided which allows groups of subscribers sharing a single account to be identified both during the call rating procedure, during which call detail records are related to add a charge to the call detail record, and/or to add a usage of a pre-paid usage allocation to be added to the call detail records, and during the production of billing details at the end of a billing period. A relational database holds usage allocation records which pertain either to a single subscriber, or to a group of subscribers. The group of subscribers may consist of any of 2 to 50, or more, subscribers, depending on the subscription type held by the group.

Abstract: A billing center for a mobile communications system is described which allows groups of subscribers sharing a single account to be identified both during the call rating procedure, during which call detail records are related to add a charge to the call detail record, and/or to add a usage of a pre-paid usage allocation to be added to the call detail records, and during the production of billing details at the end of a billing period.

Abstract: Subscribers in a mobile communications system are provided with a bundle of call time each billing period, against which standard call types are rated. If, at the end of one billing period, a portion of the bundle for that billing period remains, the rating system associates the remaining portion with a bundle provided for the forthcoming billing period. In one embodiment, rating is interrupted whilst any remaining portions of the previous bundles are added to the newly-created bundles for the next period. In other embodiments, the rating system refers both to the current bundle and to a previous bundle when rating standard call types.
