The vision of Self-Organizing Networks (SON) has been drawing considerable attention as a major axis for the development of future networks. As an essential functionality in SON, cell outage detection is developed to autonomously detect macrocells or femtocells that are inoperative and unable to provide service. Previous cell outage detection approaches have mainly focused on macrocells while the...
Diagnosis for configuration troubleshooting in femtocell networks is extremely important for end users and network operators. However, because the small-size femtocell only serves several users, the historical data are very scarce. The data scarcity makes traditional cellular troubleshooting solutions which require a large amount of historical data not applicable. In this paper, we propose a new framework...
There is a bottleneck of low efficiency in transmitting large amounts of data in service-oriented architecture, SOA. Based on distributed architecture, a query solution of modular classification combining with web services is proposed to resolve the problem in this paper. In the solution, multi-threading is used to obtain respective data from corresponding distributed database. The solution increases...
This paper presents a DRM for Service Provider to reorganize resource from different DRMs, in view of the present situation of Chinese digital publishing industry. This DRM helps SP to provide value-added service which could be quite different from CP providing, such as redistribution, recommendation, renting and so on. It repackages various DRM licenses and SP copyright control description into one...
Service-oriented architecture (SOA) is an ideal solution to build application system with low cost and high efficiency, but fault detection is not supported in most SOA-based applications. Based on Gauss distribution, a fault detection mechanism for SOA-based applications is proposed. The fault in SOA can be detected through comparing the calculated confidence interval with the predefined parameters...
The remarkable and continuous increase in link speed and application variety of Internet calls for new QoS provision technology that is both efficient and flexible. Being a kind of application-specific processor optimized for network computation, network processor (NP) combines the high performance of hardware and the flexibility of software, which exactly meets the demands of nowadays Internet traffic...
