Real-time service accounting

Abstract

Offering telematics services toward the end-users involves inter-domain real-time service provisioning, it therefore can also involves inter-domain real-time service accounting. Recognizing the increasing complexity of accounting services due to dynamic service usage behavior of the end-users, the paper addresses a way to first, decompose end-to-end service into accountable service components and second, apply formal modeling and analysis to service component accounting management.

Design of an Online Charging System to Support IMS-Based Inter-domain Composite Services

“…The rationale of the processes for the online charging of services is to intertwine the service life cycle and the charging life cycle as we have proposed in [12]. The intertwining of these two different life cycles is described by the process given in Figure 4.…”

An Enterprise Model for Real-Time Inter-domain Billing of Services

“…The rationale of the processes for the real-time billing of services is to intertwine the service usage lifecycle and the service billing lifecycle as we have proposed already in [2]. How these two different lifecycles are related, that is intertwined, is described by the process given in Figure 4.…”

“…For example, an eHealth service may consist of a connectivity service and a multimedia consultancy service [1,2]. The basic services in such a composite service may be provided by different service providers.…”

Towards an inter-domain billing system to support dynamic service provisioning

“…These two distinct life cycles, one defined for the service session and the other for the corresponding accounting and charging, act like a "gearing system" where the support of one gear to the other is the driving force for the whole system. In [Le02b,Le03], this coherence of life cycles is discussed in more detail. The relationship between the service life cycle, service session life cycle and accounting and charging life cycle is shown in Figure 3.3.…”
