In this chapter, the authors discuss innovations associated with the transition from the circuit-switched public telephone network to IP packet-switched networks for the provision of voice services by focusing on research findings in the area of quality of service (QoS). To give a meaningful answer on how this transition affects the telecommunications industry, we elaborate on the frequently-cited concept of disruptive innovations, pioneered by Harvard Professor Clayton M. Christensen.

Treat All

Today’s networks support applications that deliver text, audio, images and video, often in real time and with a high degree of interactivity, using a common infrastructure. More often than not, traffic is carried over packet-switched networks that treat all data the same, under what is known as best-effort service. Packet switching can achieve very high efficiency through statistical multiplexing of data from numerous sources; however, due to the very nature of packet switching, one should expect fluctuations in throughput, delay, reliability, etc., for any given flow. The greater the statistical multiplexing capabilities, the greater the efficiency and also the greater the variability of achieved performance; in this sense, best-effort service provides maximum efficiency with highly unpredictable service quality. Clearly, not all traffic flows are created equal. Interactive web-based applications tend to be very sensitive to throughput, while real-time voice and video are sensitive to delay and jitter, and traditional data applications such as e-mail and file transfers are fairly insensitive to fluctuations in performance. The concept of quality of service (QoS) has evolved from the realization that in networks that carry heterogeneous traffic it makes sense to treat specific classes of traffic according to their specific needs.

Factors Affecting

Marketing and strategy research has given a lot of importance to the study of product and service quality improvement. This has been widely studied in the literature as an appropriate competitive strategy to ensure customer satisfaction in the marketplace and gain a sustainable competitive advantage. In this paper, first, we have opted for an extensive review of marketing literature, quality of service and consumer satisfaction. Next, we propose to determine the factors that may affect customer satisfaction in the telecommunications industry in Tunisia. Indeed, each organization chooses to succeed in its strategy of satisfying its customers and to prevent the risk of losing them. Our empirical results indicate that most customers are satisfied with the quality of service provided to them, and most customers believe that Tunisie Telecom's service quality is above their expectations. Quality of reception at the counters of Tunisie Telecom's agencies is the key element for the success of the quality improvement project and is the major factor that can strongly influence client satisfaction and behavior.

Using Data

This chapter is interested in discussing how to use data mining techniques to assist in achieving an acceptable level of quality of service of telecommunication systems. The quality of service is defined as the metrics which are predicated by using the data mining techniques, decision tree, association rules and neural networks. Routing algorithms can use this metric for optimal path selection which in turn will affect positively on the system performance. Also, in this chapter management axis using data mining techniques were handled, i.e., check the status of the telecommunication networks, role of data mining in obtaining optimal configuration, how to use data mining technique to assure high level of security for the telecommunication. The popularity of data mining in the telecommunications industry can be viewed as an extension of the use of expert systems in the telecommunications industry. These systems were developed to address the complexity associated with maintaining a huge network infrastructure and the need to maximize network reliability while minimizing labor costs (Liebowitz, J. 1988). The problem with these expert systems is that they are expensive to develop because it is both difficult and time consuming to elicit the requisite domain knowledge from experts.

This chapter examines regulatory compliance, ethical behaviour and sustainable growth in Nigeria's telecommunications industry. It provides perspectives on the vexed issues of poor quality of service (QoS) that seems to have defied all practical solutions, unsolicited messages and the fleecing of subscribers by the mobile network operators, and other unfair business practices pervading the industry. The chapter wades through the controversy surrounding regulations and sanctions, and condemns the flagrant disregard for industry regulations by the mobile network operators whose actions are propelled by the runaway profit, which currently drives the stiff competition in the telecommunications industry. Based on the issues and problems articulated in this work, the chapter recommended among others, that the regulator should continue to engage the mobile network operators and other stakeholders in a robust dialogue aimed at finding lasting solution to the challenges impeding the growth of the telecommunications industry in Nigeria.

Performance Requirements

The original communication networks were designed to carry traffic with homogeneous performance requirements. The telephone network carried real-time voice, with stringent latency bounds, and therefore used circuit-switched technologies with fixed bandwidth allocated to each call. Original data networks were used for electronic mail and file exchange, and therefore employed packet switching and provided best-effort service.
