In recent years, cloud computing is the most popular topic on the IT industry. The underlying virtualization technologies, that make cloud computing possible, also get more and more attention. Gradually, companies move their services to the virtual host. These services include: desktop virtualization, application virtualization and database virtualization(More)
The widespread application of M2M communications is obvious. There are already many useful services enabled by M2M communications such as video surveillance, smart grid, smart home, connected vehicle, industry automation and smart city. These services are different from traditional Internet services such as e-mail, web browsing and video watching. As a(More)
With the launching of 4G services and evolving in mobile technology, data-hungry applications are ubiquitous and embraced by more and more customers. It is obvious that customers are more likely to run out of their monthly data allowance when using these applications. Therefore, network operators introduce many feasible upselling products for customers to(More)
The emerging of M2M communications enables many new applications such as smart grid, connected vehicle, eHealth and smart city. The telecom network is an ideal environment to support the implementation of these applications. However, the property of M2M communications is very different from that of traditional telecomm. Consequently, charging models(More)
Long Term Evolution (LTE) has been widely adopted by many 4G network operators. Many countries in America, Europe, and Asia have started LTE services since 2010. In the meantime, some countries (such as Taiwan and China) are in the process of transferring from 3G or Worldwide Interoperability for Microwave Access (WiMAX) to 4G services. In this paper, we(More)
Growing real-time services require discovering transient customer needs in CDRs. In this paper, we propose a CDR analytics system architecture for event-based analytics processing in real time. This system is expected to allow marketing staff to inject analytics-based rules to trigger marketing campaigns. We also propose two implementations which are based(More)
Since static pricing models (such as flat-rate or tiered-rate models) can not improve user utility for subscribers and ease network congestion for operators during peak time, Smart Data Pricing (SDP) has become an important incentive for mobile data markets. Paris Metro Pricing (PMP), which is a static pricing mode inspired by the pricing model for the(More)
Recently due to the launching of 4G services and evolving in mobile technology, it is rapidly changing and strictly competitive in telecom market. Therefore, telecom operators develop a great many of reward campaigns to encourage customers consume more data usage and to raise customer loyalty. However, reward returned to customers varies only if data usage(More)
In this paper, we study on the price comparison between shared plan and non-shared plan for mobile service. A non-shared data plan is a traditional data plan for a single user with a limited monthly data allowance. A shared data plan allows a user to add different devices to one inclusive plan and receive one bill at the end of every month, which the(More)
