Reactivity of the Organometallic fac-[(CO)3ReI(H2O)3]+ Aquaion. Kinetic and Thermodynamic Properties of H2O Substitution

In classical networks, charging and billing are important tools for customer care to fight competition and to assure the operatorʹs revenue. If charging is to remain a prime competitive tool in next-generation networks, it must be functionally intelligent and flexible, and able to optimize operator and service provider revenues while providing a fair policy toward the end users. Multimedia sessions can be considered as being composed of a number of call components, each of which might consist of different bearer and service objects. The NGN multimedia network structure and its business model define four players involved in charging: access provider, connection provider, telecommunication service provider, and value-added service provider. Often charging components must be correlated to create a clear postpaid bill and ensure correct treatment of prepaid accounts, as well as settlement between the providers involved.
