The advent and rise of broadband technologies and new applications and services have led to a complex heterogeneous scenario in which providing Quality of Service (QoS) has become a compelling issue. Furthermore, the competitive condition of the telecommunications environment has caused user’s perception of quality to become one of the most differential factors for service providers. Due to this fact, QoS must not only attend to specific technical metrics, but more important, QoS criteria should be defined to assure the level of quality to fulfil the users’ requirements. In this new context, the definition of effective user-oriented QoS management models and frameworks has become a matter of contention. This chapter aims to provide readers a comprehensive analysis of the entire significance of a user-centered approach for quality of service management. For this purpose, a review of the most important issues related to the subject is provided.

Open Service

This paper investigates the capabilities for open access to quality of service management in convergent networks. Based on the analysis of requirements for policy and charging control in Internet Protocol Multimedia Subsystem (IMS), functions for quality of service (QoS) management and charging that are available for third party applications are identified. The functionality of Open Service Access (OSA) and Parlay X interfaces is evaluated for support of dynamic QoS control, while an approach to development of OSA compliant application programming interfaces for QoS management in IMS networks is presented. The interface’s methods are mapped onto the messages of network control protocols such as Diameter and Session Initiation Protocol (SIP). Finally, aspects of interface implementation are discussed including behavior equivalence of state machines.

The chapter investigates the capabilities for open access to quality of service management in the Evolved Packet System. Based on the analysis of requirements for policy and charging control in the Evolved Packet Core, functions for quality of service (QoS) management and charging, available for third party applications, are identified. The functionality of Open Service Access (OSA) and Parlay X interfaces is evaluated for support of dynamic QoS control on user sessions. An approach to development of OSA-compliant application programming interfaces for QoS management in the Evolved Packet System is presented. The interface’s methods are mapped onto the messages of network control protocols. Aspects of interface implementation are discussed, including interface to protocol conversion.

Latency Jitter

Multimedia services like television programs and live streaming of mobile videos can be delivered to mobile terminals via different access technologies. The question is – how do users perceive such services on mobile terminals? The objective of this study is to find the correlation between video quality thresholds and the user context. Our study reveals the thresholds of user's quality of experience (QoE) in a mobile environment by using different categories of content types, in relation to different access technologies and terminal capability. The mobile terminals used are: – (i) 3G Mobile Phone (ii) Personal Digital Assistant (PDA) and (iii) Laptop. We argue that quality of service (QoS) management should be driven by the user perception of quality rather than resulting from raw engineering parameters such as latency, jitter, bandwidth etc. Our results will be of great interest to network operators, service providers, terminal manufacturers, and researchers working in the area of quality of service management.

Practical Recommendations

The market for shared mobility services is growing very quickly. New types of vehicles have been introduced, and the offer of available services and functionalities has expanded, the purpose of which is to improve the quality of service. Despite all the improvements, it is still not possible to speak of achieving full availability of systems that meet the needs of users. This is due to the reluctant involvement of operators of shared mobility systems in joining Mobility as a Service platforms based on the idea of open innovation. The aim of the article is to analyze the factors influencing the limitations in the development of open innovations in the form of Mobility as a Service (MaaS) services. The authors focus on identifying the challenges and concerns faced by shared mobility service providers. The article supports the development of the concept of open innovation in shared mobility services. It also contains practical recommendations for the development of MaaS systems. The results of the developed research can be used by operators of shared mobility services, transport authorities, or IT service providers providing MaaS services to strengthen cooperation and integration using the language of mutual benefit.

Transactional Costs

Mobile money is an electronic wallet service that allows users to store, send and receive money using their mobile phone. This research is an effort to find out the adoption and utilization of mobile money services in small sized enterprises located in Gaborone, Botswana. Inevitably, other aspects such as different types of transactions carried out using mobile money services in small business, customer’s perception on quality of mobile money service providers, impeding factors of mobile money adoption are also studied for wider understanding of the subject. The findings of the study show that small enterprises use mobile money services to carryout transactions but the level of adoption is not significant. The study revealed that transactional costs and connectivity issues are major barriers of adoption of mobile money services. In conclusion the study recommended that the service providers must improve the connectivity issues and reduce transaction charges in order to increase the utilization of mobile money services
