Developing a simulator application to test the billing platform in telecom industry

Billing Mediation Platform (BMP) in telecommunication industry is used to process real-time streams of Call Detail Records (CDRs) which can be a massive number a day. The generated records by BMP can be deployed for billing purposes, fraud detection, spam filtering, traffic analysis, and churn forecast. Several of these applications are distinguished by real-time processing requiring low-latency analysis of CDRs. Testing of such a platform carries diverse aspects like stress testing of analytics for scalability and what-if scenarios which require generating of CDRs with realistic volumetric and appropriate properties. The approach of this project is to build user friendly and flexible application which assists the development department to test their billing solution occasionally. These generators projects have been around for a while the only difference are the potions they cover and the purpose they will be used for. This paper proposes to use a simulator application to test the BMPs with simulating CDRs. The Simulated CDRs are modifiable based on the user requirements and represent real world data.

Australia lawyer well-being : workplace demands, resources and the impact of time-billing targets

The purpose of the present study was to examine the types of workplace demands and resources experienced by full-time Australian lawyers, and the prevalence of a range of psychological outcomes. The study further focussed on the impact of time-billing targets on lawyers’ experience of these variables. Participants were 384 full-time Australian lawyers who completed an online questionnaire distributed by their Australian State or Territory Law Society. Analysis revealed that emphasis on profits within the workplace was the highest perceived demand, and the perception of social value in their work was the highest available resource. The results indicated that 37% of participants displayed Moderate to Extremely Severe depressive symptoms, and 35% were a positive screen for hazardous or harmful drinking. A series of three multivariate analyses of variance revealed significant differences between non-billers, low-to-moderate billers and high billers, with high billers experiencing greater demands, fewer resources and poorer psychological outcomes. The practical applications of these results for the legal profession are discussed.

Integrated billing mechanisms in the Internet of Things to support information sharing and enable new business opportunities

The Internet of Things (IOT) concept and enabling technologies such as RFID offer the prospect of linking the real world of physical objects with the virtual world of information technology to improve visibility and traceability information within supply chains and across the entire lifecycles of products, as well as enabling more intuitive interactions and greater automation possibilities. There is a huge potential for savings through process optimization and profit generation within the IOT, but the sharing of financial benefits across companies remains an unsolved issue. Existing approaches towards sharing of costs and benefits have failed to scale so far. The integration of payment solutions into the IOT architecture could solve this problem. We have reviewed different possible levels of integration. Multiple payment solutions have been researched. Finally we have developed a model that meets the requirements of the IOT in relation to openness and scalability. It supports both hardware-centric and software-centric approaches to integration of payment solutions with the IOT. Different requirements concerning payment solutions within the IOT have been defined and considered in the proposed model. Possible solution providers include telcos, e-payment service providers and new players such as banks and standardization bodies. The proposed model of integrating the Internet of Things with payment solutions will lower the barrier to invoicing for the more granular visibility information generated using the IOT. Thus, it has the potential to enable recovery of the necessary investments in IOT infrastructure and accelerate adoption of the IOT, especially for projects that are only viable when multiple benefits throughout the supply chain need to be accumulated in order to achieve a Return on Investment (ROI). In a long-term perspective, it may enable IT-departments to become profit centres instead of cost centres. © 2010 - IOS Press and the authors. All rights reserved.

Economic valuation of collecting water to billing in the aspersion irrigated bean in the no tillage system and conventional crop

The law's project n.676/2000 approved the collecting of billing water for farmers in a maximum foreseen value of US$ 0.01 m(-3) of extracted water in the São Paulo State. As the irrigated agriculture is the activity that consumes more water, the farmers profitability can be affected. This work was to analyze the economic impact of billing water in the aspersion irrigated bean crop to consider the system of conventional production and no tillage system in the Paranapanema municipal district, São Paulo State, Brazil. The indicators used to analyze the economic results were unit variable cost, market price and unit profitability. The results showed that for the aspersion irrigated bean crop in conventional system, the participation of cost to the recourse water in cost variable totality was of 2.5% and in no tillage system the participation was of 2.2%. The fall of profitability just the billing water in conventional crop system and in no tillage system was US$ 0.01 kg(-1).

Sistemi per la rilevazione di frodi nel "Carrier Billing"

Il rilevamento e l’analisi delle frodi è una delle attività cruciali per un sistema di carrier billing. Una frode non rilevata prontamente può causare ingenti danni economici, mentre un falso positivo porta ad uno spreco di tempo da parte del team di Reporting and Control. In questa tesi viene studiato il dominio di un Payment Service Provider (PSP) operativo nel settore del carrier billing, andando ad approfondire il sistema di rilevamento delle frodi basato sull’analisi di serie storiche con la tecnica Holt-Winters. Verrà fornita una panoramica sull’architettura del sistema seguita da alcuni esempi in cui la scarsa qualità delle predizioni ha causato una perdita economica o temporale al PSP. Verranno quindi proposte numerose soluzioni per estendere e migliorare il sistema attuale, concentrandosi principalmente sulla pulizia dei dati da analizzare e sullo sfruttamento di informazioni implicitamente contenute nei dati. I miglioramenti apportati possono essere divisi in due categorie: quelli che necessitano della supervisione dell’essere umano e quelli che possono essere ottenuti in modo automatico da un algoritmo. Alcune di queste soluzioni verranno implementate e commentate confrontando le prestazioni del sistema prima e dopo le varie implementazioni. Alcune proposte verranno invece trattate solamente a livello teorico ma faranno parte degli sviluppi futuri. Infine si cercherà di trarre delle conclusioni, dimostrando come nel dominio del carrier billing sia possibile ottenere prestazioni soddisfacenti grazie ad un filtraggio supervisionato dei dati delle serie storiche, mentre i tentativi di filtraggio non supervisionato hanno fornito risultati contrastanti.

Estimates of hospital and physician costs of epilepsy in the United States for 1995 comparing the provider -based survey method and a patient -based medical charts and billing method

This investigation compares two different methodologies for calculating the national cost of epilepsy: provider-based survey method (PBSM) and the patient-based medical charts and billing method (PBMC&BM). The PBSM uses the National Hospital Discharge Survey (NHDS), the National Hospital Ambulatory Medical Care Survey (NHAMCS) and the National Ambulatory Medical Care Survey (NAMCS) as the sources of utilization. The PBMC&BM uses patient data, charts and billings, to determine utilization rates for specific components of hospital, physician and drug prescriptions. ^ The 1995 hospital and physician cost of epilepsy is estimated to be $722 million using the PBSM and $1,058 million using the PBMC&BM. The difference of $336 million results from $136 million difference in utilization and $200 million difference in unit cost. ^ Utilization. The utilization difference of $136 million is composed of an inpatient variation of $129 million, $100 million hospital and $29 million physician, and an ambulatory variation of $7 million. The $100 million hospital variance is attributed to inclusion of febrile seizures in the PBSM, $−79 million, and the exclusion of admissions attributed to epilepsy, $179 million. The former suggests that the diagnostic codes used in the NHDS may not properly match the current definition of epilepsy as used in the PBMC&BM. The latter suggests NHDS errors in the attribution of an admission to the principal diagnosis. ^ The $29 million variance in inpatient physician utilization is the result of different per-day-of-care physician visit rates, 1.3 for the PBMC&BM versus 1.0 for the PBSM. The absence of visit frequency measures in the NHDS affects the internal validity of the PBSM estimate and requires the investigator to make conservative assumptions. ^ The remaining ambulatory resource utilization variance is $7 million. Of this amount, $22 million is the result of an underestimate of ancillaries in the NHAMCS and NAMCS extrapolations using the patient visit weight. ^ Unit cost. The resource cost variation is $200 million, inpatient is $22 million and ambulatory is $178 million. The inpatient variation of $22 million is composed of $19 million in hospital per day rates, due to a higher cost per day in the PBMC&BM, and $3 million in physician visit rates, due to a higher cost per visit in the PBMC&BM. ^ The ambulatory cost variance is $178 million, composed of higher per-physician-visit costs of $97 million and higher per-ancillary costs of $81 million. Both are attributed to the PBMC&BM's precise identification of resource utilization that permits accurate valuation. ^ Conclusion. Both methods have specific limitations. The PBSM strengths are its sample designs that lead to nationally representative estimates and permit statistical point and confidence interval estimation for the nation for certain variables under investigation. However, the findings of this investigation suggest the internal validity of the estimates derived is questionable and important additional information required to precisely estimate the cost of an illness is absent. ^ The PBMC&BM is a superior method in identifying resources utilized in the physician encounter with the patient permitting more accurate valuation. However, the PBMC&BM does not have the statistical reliability of the PBSM; it relies on synthesized national prevalence estimates to extrapolate a national cost estimate. While precision is important, the ability to generalize to the nation may be limited due to the small number of patients that are followed. ^

Skin cancer clinics in Australia: workload profile and performance indicators from an analysis of billing data

Objective: To describe the workload profile in a network of Australian skin cancer clinics. Design and setting: Analysis of billing data for the first 6 months of 2005 in a primary-care skin cancer clinic network, consisting of seven clinics and staffed by 20 doctors, located in the Northern Territory, Queensland and New South Wales. Main outcome measures: Consultation to biopsy ratio (CBR); biopsy to treatment ratio (BTR); number of benign naevi excised per melanoma (number needed to treat [NNT]). Results: Of 69780 billed activities, 34 622 (49.6%) were consultations, 19 358 (27.7%) biopsies, 8055 (11.5%) surgical excisions, 2804 (4.0%) additional surgical repairs, 1613 (2.3%) non-surgical treatments of cancers and 3328 (4.8%) treatments of premalignant or non-malignant lesions. A total of 6438 cancers were treated (116 melanomas by excision, 4709 non-melanoma skin cancers [NMSCs] by excision, and 1613 NMSCs non-surgically); 5251 (65.2%) surgical wounds were repaired by direct suture, 2651 (32.9%) by a flap (of which 44.8% were simple flaps), 42 (0.5%) by wedge excision and 111 (1.4%) by grafts. The CBR was 1.79, the BTR was 3.1 and the NNT was 28.6. Conclusions: In this network of Australian skin cancer clinics, one in three biopsies identified a skin cancer (BTR, 3.1), and about 29 benign lesions were excised per melanoma (NNT, 28.6). The estimated NNT was similar to that reported previously in general practice. More data are needed on health outcomes, including effectiveness of treatment and surgical repair.

A New Charging and Billing Model and Architecture for the Ubiquitous Consumer Wireless World

In a Ubiquitous Consumer Wireless World (UCWW) environment the provision, administration and management of the authentication, authorization and accounting (AAA) policies and business services are provided by third-party AAA service providers (3P-AAA-SPs) who are independent of the wireless access network providers (ANPs). In this environment the consumer can freely choose any suitable ANP, based on his/her own preferences. This new AAA infrastructural arrangement necessitates assessing the impact and re-thinking the design, structure and location of ‘charging and billing’ (C&B) functions and services. This paper addresses C&B issues in UCWW, proposing potential architectural solutions for C&B realization. Implementation approaches of these novel solutions together with a software testbed for validation and performance evaluation are addressed.

Professional Responsibility and Legal Ethics in Queensland

With the commencement of the Legal Profession Act 2007 (Qld) and the establishment of the Legal Services Commission, the legal profession and legal services market in Queensland has experienced significant changes to its regulatory environment. Professional Responsibility and Legal Ethics in Queensland provides a detailed explanation and analysis of these changes. The book will assist lawyers to plan for successful practice within this new environment by examining such topics as: • The scope and application of key provisions within the Legal Profession Act; • The role, functions and policies of the Legal Services Commission; • The ethical and regulatory implications of operating as an Incorporated Legal Practice or as a Multi-Disciplinary Partnership; • Developments affecting trust accounts and client money dealings more generally; • Recent case law, Tribunal decisions and Legal Services Commission guidelines in relation to the new conduct standards of Unsatisfactory Professional Conduct and Professional Misconduct; and • The impact of the new legislation and regulatory environment on a range of traditional ethical duty categories such as the duty to communicate, costs and billing practices, as well as the paramount duties to the court and to the administration of justice. An invaluable reference for legal professionals, this book is also an important resource for law students grappling with questions raised by legal ethics and their application to the workplace.

Determinants and consequences of information sharing with key suppliers

The economic environment of today can be characterized as highly dynamic and competitive if not being in a constant flux. Globalization and the Information Technology (IT) revolution are perhaps the main contributing factors to this observation. While companies have to some extent adapted to the current business environment, new pressures such as the recent increase in environmental awareness and its likely effects on regulations are underway. Hence, in the light of market and competitive pressures, companies must constantly evaluate and if necessary update their strategies to sustain and increase the value they create for shareholders (Hunt and Morgan, 1995; Christopher and Towill, 2002). One way to create greater value is to become more efficient in producing and delivering goods and services to customers, which can lead to a strategy known as cost leadership (Porter, 1980). Even though Porter (1996) notes that in the long run cost leadership may not be a sufficient strategy for competitive advantage, operational efficiency is certainly necessary and should therefore be on the agenda of every company. ----- ----- ----- Better workflow management, technology, and resource utilization can lead to greater internal operational efficiency, which explains why, for example, many companies have recently adopted Enterprise Resource Planning (ERP) Systems: integrated softwares that streamline business processes. However, as today more and more companies are approaching internal operational excellence, the focus for finding inefficiencies and cost saving opportunities is moving beyond the boundaries of the firm. Today many firms in the supply chain are engaging in collaborative relationships with customers, suppliers, and third parties (services) in an attempt to cut down on costs related to for example, inventory, production, as well as to facilitate synergies. Thus, recent years have witnessed fluidity and blurring regarding organizational boundaries (Coad and Cullen, 2006). ----- ----- ----- The Information Technology (IT) revolution of the late 1990’s has played an important role in bringing organizations closer together. In their efforts to become more efficient, companies first integrated their information systems to speed up transactions such as ordering and billing. Later collaboration on a multidimensional scale including logistics, production, and Research & Development became evident as companies expected substantial benefits from collaboration. However, one could also argue that the recent popularity of the concepts falling under Supply Chain Management (SCM) such as Vendor Managed Inventory, Collaborative Planning, Replenishment, and Forecasting owe to the marketing efforts of software vendors and consultants who provide these solutions. Nevertheless, reports from professional organizations as well as academia indicate that the trend towards interorganizational collaboration is gaining wider ground. For example, the ARC Advisory Group, a research organization on supply chain solutions, estimated that the market for SCM, which includes various kinds of collaboration tools and related services, is going to grow at an annual rate of 7.4% during the years 2004-2008, reaching to $7.4 billion in 2008 (Engineeringtalk 2004).
