云计算环境下基于Mashup的一种电信网络能力服务提供模式

随着高速发展的互联网和移动通信在业务层面的逐渐融合,国内运营商所采用的"封闭花园"模式的业务架构已经面临各种挑战,因此需要更多地考虑如何有效引入互联网业务和服务模式,不断提升用户体验。在电信运营商逐步开放其电信能力API的背景下,基于Mashup的业务构建模式,提出了一种云计算环境下的电信网络能力服务提供模式。该模式将Mashup的理念移植到电信能力上,并将电信能力封装成Web Element的形式呈现给用户,进一步提升了电信网络能力服务的抽象层次。这种电信能力应用模式打破了电信能力拘泥于手持终端的传统形式,提出了一种新的适合于Web2.0环境的电信网络能力服务提供模式。在"OMP(Open Mobile Internet Platform)应用运行和开发引擎算法及功能研发"项目中的试用证明了其可行性。     

Competency rallying in electronic markets: implications for open source project success

This paper studies the success of Open Source Software (OSS) projects in attracting developer interest and achieving project efficiency. The focus of our study is on examining the relationship between the four sets of capabilities proposed in the Theory of Competency Rallying (TCR) and the success of OSS projects. The data collected from 607 OSS projects mainly confirm that the capabilities proposed in the TCR are necessary for the success of OSS projects. The results of this study show that in order to succeed, OSS projects should constantly identify their market??s quality and functionality needs. Ability of OSS project managers to know which developers possess certain skills required to meet a particular market need is also found to be critical. Another capability that is recognised to be crucial in predicting project success is the ability of OSS developers in effectively addressing market needs and continuously learning from such experiences. Finally, the ability of stakeholders involving in addressing a particular market need to efficiently collaborate and fulfil that specific market need is found to be another essential capability required for OSS projects to succeed. Implications of the results for practitioners and the research community are presented.     

Reliability assessment based on hazard rate model for an embedded OSS porting‐phase

Embedded Open Source Software (OSS) systems have been gaining a lot of attention in the embedded system area. The successful experience of embedded OSSs include Android, BusyBox, TRON, etc. Also, OSS market will be expanded not only to mobile phone OSS areas but also to other embedded OSS areas in the future. However, the poor handling of quality problem and customer support prohibit the progress of embedded OSS. Also, it is difficult for developers to assess the reliability and portability of embedded OSS on a single‐board computer. A method of software reliability assessment based on flexible hazard rate modeling for the embedded OSS is proposed in this paper. Also, several numerical examples are shown by using actual data. Moreover, this paper compares the proposed model with the conventional hazard rate models by using the comparison criteria of goodness‐of‐fit. Copyright © 2011 John Wiley & Sons, Ltd.     

A framework for creating hybrid-open source software communities

Abstract The open source software (OSS) model is a fundamentally new and revolutionary way to develop software. The success of the OSS model is also setting the stage for a structural change in the software industry; it is beginning to transform software industry from manufacturing to a service industry. Despite the success of the OSS model, for‐profit organizations are having difficulty building a business model around the open source paradigm. Whereas there are some isolated empirical studies, little rigorous research has been done on how traditional organizations can implement and benefit from OSS practices. This research explores how organizations can foster an environment similar to OSS to manage their software development efforts to reap its numerous advantages. Drawing on organizational theory, we develop a framework that guides the creation and management of a hybrid‐OSS community within an organization. We discuss the implications of this framework and suggest areas for future research.

Towards Standardized and Automated Fault Management and Service Provisioning for NGNs

The IP Multimedia Subsystem (IMS), already widely recognized as a fundamental core component of Next Generation Networks (NGNs), enables proliferation of a huge variety of value added services. Simultaneous to the emergence of triple play services there is a strong need for establishing standardized methodologies for service fulfillment and assurance, maintaining service execution parameters at advertised levels. Traditional Operations Support Systems (OSS) are not adequate for managing NGNs. This work shows experiences gained from implementing OSS for NGNs. It describes a solution that combines extensive NGN development expertise with a new generation, of policy-based, service oriented OSS solutions in order to provide enhanced levels of automation and reliability to the NGN service delivery and session control environment. Primary focus of this approach is put on service assurance and service fulfillment mechanisms for remote monitoring, automated control and configuration of standard compliant IMS infrastructures, such as the Open Source IMS Core (OSIMS) based Open IMS Playground. This work describes state of the art NGN OSS design principles and knowledge attained by integration of standardized fault management as well as service and subscriber provisioning procedures showing how the full cycle from service deployment to service advertisement to service execution can be delivered in an automated way.

Evaluating mobile app usage by service sector micro and small enterprises in Nigeria: an abductive approach

ABSTRACT

This research investigated how mobile apps influence the dynamic capabilities of service sector micro and small enterprises (MSEs) in Lagos, Nigeria. Using an abductive method, data from 388 service sector MSEs was examined through exploratory factor analysis. The resultant model suggests that mobile app usage barely increases the absorptive capability (integrating new learning into the organization) of MSEs; rather, it strongly influences the ability to seize opportunities. The result implies that mobile app usage by service sector MSEs in Lagos deviates from the conventional views on the micro foundations of the dynamic capability framework, which argues that sensed opportunities are first analysed (shaped) before resources are deployed towards their maximization. These findings suggest that the service sector MSEs in Lagos seldom scrutinize opportunities before deploying resources to seize them. This study extends IS literature on how mobile apps help MSEs to exploit business opportunities in resource-constrained contexts.

移动计算环境下的个人化服务发布和组装

随着移动计算技术的发展,移动设备用户可以服务的方式共享移动设备及其周围设备的计算能力和计算资源.然而,移动设备的私有性、资源受限性以及移动性等特征使得这种基于移动设备提供的个人化服务在发布和组装方面存在着一些特殊问题,例如用户隐私、移动设备资源消耗、网络环境变化引起的失效问题等.针对以上这些问题,提出一种移动计算环境下的个人化服务发布和组装方法.该方法在个人化服务发布过程中引入了服务意愿的概念,并在服务选择过程中综合考虑了服务意愿和服务效用.此外,还提出了资源感知的心跳机制来定期更新服务选择所依赖的设备及服务状态信息,从而解决由于网络环境变化等引起的服务失效问题.基于该方法,提出了一个基于JADE和OSGi的实现框架.通过一个案例分析,验证了所提出的实现框架的有效性以及在移动计算环境下考虑服务意愿的合理性.     

Empirical study of open source software selection for adoption,based on software quality characteristics

Currently, open source software (OSS) products have started to become popular in the market as an alternative to traditional proprietary or closed source software. Governments and organizations are beginning to adopt OSS on a large scale and several governmental initiatives have encouraged the use of OSS in the private sector. One major issue for the government and private sector is the selection of appropriate OSS. This paper uses new internal quality characteristics for selecting OSS that can be added to the dimensions of DeLone and McLean information systems’ model. Through this study, the quality characteristics are organized in a two level hierarchy, which list characteristics and sub-characteristics that are interconnected with three main dimensions: system quality, information quality and service quality. These characteristic dimensions are tailored to the criteria having been built from literature study and standard for software quality and guidelines. This paper presents case study results of applying the proposed quality characteristic on eight different open source software that are divided between open source network tools and learning management systems.
