In the framework of the LIAISON (location bAsed services for the enhancement of wOrking enviroNment) IP project the existing legendary charging functionality is complemented with new features fulfilling the emerging charging requirements for an integrated environment providing mobile workers with location-based services. In that scope, LIAISON introduces the LIAISON customised billing module (namely the LCBM), an integrated customised billing module, which collects the charging information from each, potentially different, business domain, calculates the charges that are due to each involved business entity and shares the respective revenues. The LCBM covers the emerging requirements of an integrated environment enabling LIAISON solution to provide mobile workers with advanced location-based services. It receives charging information from heterogeneous environments through open application programming interfaces (APIs), applies the appropriate pricing policy based on the user or/and service profile and calculates the apportioning revenues between the actors.
