Cellular operators offer voice services for years and own a solid amount of users with a certain authority on running cellular business. Recently, various fascinated value added contents and services are emerging in the post-voice era. To extend the business and leverage the exiting operation and maintenance systems, operators strive to become a trusty broker that aggregates a variety of valued added services provided by lots of third-party service/content providers as well as a payment agency that collects the service/content fees into a unified bill for users. In the past, little studies had ever clearly and deeply revealed for how to practically substantiate a lightweight system for connecting users, cellular operators and content/service providers by highly exploiting the mature cellular environment to achieve a triple-win situation. In this article, we elaborate a well-constructed A.A.A. brokering system – A4BS sitting between the content/service providers and users to link the value chain in such a triple-play game. A4BS generalizes certain basic mechanisms that govern authentication, authorization, advice-of-charge issuing, accounting, billing and settlement. Through this tried-and-true system, content/service providers can focus on service creation without much attention to the end-user billing. Meanwhile, users can be charged on a transaction basis with an instant expenditure notification and have a one-stop payment in the existing cellular bill.
As cellular business has been taking off, cellular services are deemed indispensable for most people in the daily life. In the post-voice era, value added contents and services are booming. Many efforts are put on service platform construction  and , content pricing , and complex charging models  and . Cellular operators strive to conduct a drive-through culture to get contents/services instantly via people’s hand-held devices. Cellular users can therefore easily purchase various fascinated value added contents/services from the one-stop service center which may be operated by cellular operators and then pay the content/service fees in their monthly bill later. On the other hand, content/service providers (CPs/SPs) may broaden their product visibility through cellular operator’s assistance and earn more revenues back without investing too many advertising efforts. CPs/SPs may consequently pay more attention to the content/service innovation without worrying about annoying payment logistics toward end users. Moreover, with the endorsement from the reputed operators, customers may alleviate their anxiety while conducting transactions in the cyber world. In accordance with the reputation of operation, cellular operators can build a trustworthy relationship among cellular users and content/service providers to conduct a network-operator-centric business  like i-mode as Fig. 1 shows. A middle-tier system must play the central role in-between in such a model and the cellular operator controls the user’s profile and charging. The developing OSA/Parlay charging API  introduced by 3GPP  seems an ideal but under-constructed and future-fully-realized solution to place the network operator again in the central role of service provisioning  and . However, cellular operators strive not to alienate their users and keep its predominance before such a perfect world comes true. In the past, little studies had ever clearly and deeply revealed for how to practically substantiate a lightweight system for connecting users, cellular operators and content/service providers by highly exploiting the mature cellular environment to achieve a triple-win situation. In this article, a well-constructed A.A.A. brokering system sitting between CPs/SPs and users to link the value chain in such a triple-play game is presented. To simply realize this concept, we build a lightweight system, which generalizes certain basic mechanisms that govern authentication, authorization, advice-of-charge, accounting, billing, and settlement (thereafter referred to as “A4BS”). Through this system, content/service providers can focus on service creation without much attention to the end-user billing. Meanwhile, users can be charged on a transaction basis with an instant expenditure notification and conduct a one-stop payment in a single cellular bill as well. The rest of this paper is organized as follows. Section 2 describes the architectural overview, the system components, and the functionality of each component in A4BS. Session 3 depicts a thorough transaction process flow. Session 4 presents the design and implementation of A4BS and covers some empirical experiments to analyze the system performance in term of the time consumption for some major processes as well as complete transaction time through different access channels from user viewpoint. Concluding remarks are finally drawn in Section 5.

In the post-voice era, people in the mobility world attentively gaze at the growth of valued added services. A neutral connector between users and CPs/SPs draws people’s attention. Cellular operators have already built a good environment to make service-getting more easily with a trustworthy reputation and to instantly carry digital contents and services from CPs/SPs to users. In the past, little studies had ever been fastened at practically establishing a lightweight system to bridge the value chain between users and CPs/SPs with highly taking advantage of the existing mature cellular environment. In this paper, a middle system – A4BS is proposed and constructed to take charge of the user authentication/authorization/accounting delegation for CPs/SPs and issuing advice-of-charge to users. In addition, A4BS provides flexible billing and settlement mechanisms to CPs/SPs and conducts a real-time expenditure charging/notification and a unified bill for users. Furthermore, A4BS enables all involved business partners to register their contents or services, to define the rating policies, to submit their charging items, to receive the usage statistics, and finally to apportion revenues under the administrative domain of cellular operators and CPs/SPs.
