Authentication protocols for the broadband ISDN billing system

The broadband integrated services digital network (B-ISDN) offers a wide variety of services to its customers. From both provider's and user's perspective, a fair and flexible billing system is indispensable to the operation of B-ISDN. In this paper, we discuss different billing policies, and their corresponding authentication protocols, which can be used by the B-ISDN billing system. Flat rate and usage-based rate are two most frequently used billing policies. Because of the diversity of B-ISDN services, combining these two billing policies, along with priority pricing, is a feasible scheme for designing a B-ISDN billing system. The membership authentication protocol (MAP) and the personal authentication protocol (PAP) are proposed to support the authentication requirements of the flat rate and usage-based rate billing policies, respectively. The MAP applies the cipher block chaining (CBC) encryption in the two-party authentication protocol, while the PAP is a modified version of the station-to-station (STS) authentication protocol. Both protocols are designed in conjunction with a suggested key management method. Cryptanalysis shows that both the MAP and the PAP are very secure. Simulation results indicate that both protocols are efficient for providing mutual authentication. Together, these two protocols provide a good authentication mechanism to the B-ISDN billing system.

Applying Bayesian Belief Network approach to customer churn analysis: A case study on the telecom industry of Turkey

In telecommunication industry, for many organizations, it is really important to take place in the market. As competition increases between companies, customer churn becomes a great issue to deal with by the telecommunication providers. For an effective churn management, companies try to retain their existing customers, instead of acquiring new ones. Previous researches focus on predicting the customers with a propensity to churn in telecommunication industry. In this study, a model is constructed by Bayesian Belief Network to identify the behaviors of customers with a propensity to churn. The data used are collected from one of the telecommunication providers in Turkey. First, as only discrete variables are used in Bayesian Belief Networks, CHAID (Chi-squared Automatic Interaction Detector) algorithm is applied to discretize continuous variables. Then, a causal map as a base of Bayesian Belief Network is brought out via the results of correlation analysis, multicollinearity test and experts’ opinions. According to the results of Bayesian Belief Network, average minutes of calls, average billing amount, the frequency of calls to people from different providers and tariff type are the most important variables that explain customer churn. At the end of the study, three different scenarios that examine the characteristics of the churners are analyzed and promotions are suggested to reduce the churn rate.     

Correlates of using the billing system of a mobile network operator to pay for digital goods and services

In many countries mobile network operators (MNOs) offer their customers the possibility to pay for digitized content, applications or services which they buy over their mobile smartphone via the carriers’ billing systems. To date, customer take-up of this mobile carrier billing (MCB) payment option is predominantly modest. At the same time, there is little empirical evidence on individual level factors significantly associated with the acceptance of MCB payment which differentiates firstly the principal adoption of the service in the sense of a yes-or-no decision and secondly the intensity of service usage among adopters. Therefore, the present study explores correlates between a total of 10 socio-demographic, contract-, communication habits- and smartphone-related variables on the one hand and the two MCB payment acceptance criteria on the other in a sample of 5010 postpaid residential customers of the German subsidiary of a multinational MNO. In contrast to many prior investigations, MCB payment adoption and usage intensity measures in the present work reflect real (and not retrospective subjective estimates of or intended) payment behaviors. A Probit regression analysis indicates that, compared to non-adopters, customers who have paid via MCB are male, have a shorter MNO tenure, have higher mobile service spending, generate more mobile Internet traffic, send more SMS and use a smartphone whose OS manufacturer offers MCB payment on its own online market place. In the subsample of adopters of MCB payments higher mean monthly MCB settlement amounts are generated by male and older subscribers who have a shorter MNO tenure, create more mobile Internet traffic, use mobile voice telephony more and SMS less heavily and who are equipped with a smartphone whose OS manufacturer does not offer MCB payment on its online market place. Findings are discussed in terms of their implications for scholarly research on antecedents of the acceptance of novel telecommunication-based service offerings such as MCB payments and of basic levers of MNOs for improving the customer take-up of their MCB payment offerings and the usage intensity of the service among its adopters.
