Media Delivery to Remote Renderers Controlled by the Mobile Phone
2009
In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.
An Innovative Pricing Method for Telecommunication Services Pricing through American Options
2009
With the evolution of telecommunication networks and of their services the role of service provider is changed, so nowadays there is a coexistence of Network Operators and Virtual Operators. The difference between these players is not in the way they offer a service but primarily in their economic objectives and risk attitudes. Essentially, Network Operators own their infrastructures and typically have to sustain both fixed costs (CAPEX) and recurrent costs (OPEX), while Virtual Operators may have a simpler cost structure, mainly consisting of OPEX for the hire of network resources. Since these two operators can provide the same service in two different markets, their objectives differ subs…
American Options Based Service Pricing For Virtual Operators
2008
In the recent years, the role of service provider has split into two broad categories: Network Operators, offering services over their networks, and Virtual Operators, providing services over leased resources. What differentiates these players is to a minor extent a matter of enhanced service offer, and primarily a matter of economic objectives and risk attitudes. Essentially, Network Operators own their infrastructures and typically have to sustain both fixed costs (CAPEX) and recurrent costs (OPEX), while Virtual Operators may have a simpler cost structure, mainly consisting of OPEX for hiring the network. Correspondingly, the objectives of these players may differ profoundly: on one hand…
Revenue-Aware Resource Allocation in the Future Multi-Service IP Networks
2006
In the future IP networks, a wide range of different service classes must be supported in a network node and different classes of customers will pay different prices for their used node resources based on their Service-Level-Agreements. In this paper, we link the resource allocation issue with pricing strategies and explore the problem of maximizing the revenue of service providers in a network node by optimally allocating a given amount of node resources among multiple service classes. Under the linear pricing strategy, the optimal resource allocation scheme is derived for the case that no firm Quality-of-Service (QoS) guarantees are required for all service classes, which can achieve the …
An effective opportunistic maintenance policy for a global service
2010
The aim of the present paper is to develop a model for an effective maintenance policy with refer to a global service contract between a services provider company and a company for the waste management. The contract requires, with fixed performance levels of the service, the supplying of a mandatory set of maintenance services on a set of waste compactors vehicles of the outsourcer company. In particular, the service provider (SP) must perform corrective maintenance actions and the replacement of the fault parts. The tackled problem concerns the determination of an effective opportunistic maintenance policy in order to assure the required service performance levels at the minimum global mai…
Modeling Ordinal Item Responses via Binary GLMMs and Alternative Link Functions: An Application to Measurement of a Perceived Service Quality
2010
Evaluation of a service on the basis of consumer opinion is a widespread practice in many fields. The assessment of perceived quality [7] of a service is generally carried out through administration of a questionnaire, composed of several items with responses posed on an ordinal scale, whereby each item represents an important feature of the evaluated service [3, 7]. In this context, the aim is to evaluate something similar to the external effectiveness, that is the part of efficacy related to the satisfaction expressed by the service users for the provided service. A particular and important example of service users is represented by students’ responses measuring the perceived quality of s…
Case study for 3G/UMTS services and billing methods
2001
The 3G/UMTS-networks and services will provide a wide range of telecommunication services. To achieve, this, we need a new view to networks, network services and service abilities. The amount of service providers in the 3G networks will be at least the same than in the present Internet. The amount of users in the 3G networks will overgrow the user amount of Internet forming a global worldwide communication society. This paper discusses customer billing in the 3G world. There are some main issues that are not very, clear to all 3G service and network providers, which however, should be settled before, 3G networks are operational. One of the most important matters is the QoS (Quality of Servi…
The four spheres of value co-creation in humanitarian professional services
2021
PurposeThe study focuses on the value co-creation processes in humanitarian professional services provision, analysing the key enabling factors of beneficiaries' participation, involved in long-term integration programmes (L-TIPs).Design/methodology/approachThrough an in-depth case study, the research looks at the practices of value co-creation in humanitarian professional services, considering both the perspectives of the professional service provider and beneficiary.FindingsIn professional services beneficiary's participation affects the success of the L-TIPs outcomes. Participation's enablers can be classified into four different spheres, each belonging to different elements of professio…
Using WMS log files as an indicator of QoS and application performance in on-demand streaming videos
2012
When utilizing video streaming for professional purposes, the quality of service needs to be evaluated by the service provider. This is the case especially when the service must be available for a large number of customers with a wide range of network interfaces and terminal equipment. Service providers have usually information about network-level metrics. However, the problem is that conditions that appear similar in a networklevel may cause very different responses in an application level, and the other way round. In this article, we study how Windows Media Server's log files can be used to evaluate the QoS of video transmission, and we also examine the application level performance based…
Transportation Services as Specific Logistics Projects for Oversized Cargo in Poland
2016
Market observation demonstrates that the transportation-freight forwarding-logistics sector carries out diverse projects based on clients’ orders. The majority of those orders are unique and project related. Recently, the project approach to logistics has gained significance. Logistics project management is a relatively new area of knowledge about logistics and supply chains. The paper presents the essence and characteristics of transportation services as a specific logistics project. The authors characterize the transportation-freight forwarding-logistics sector, with particular focus on the sector of oversized cargo transportation. The demand for such services depends on the industry, ene…
