We are transforming the current data agnostic Mobile Communication Network into a Smart Mobile Network that is semantically aware of the data types, data content, network context, handset context, user context, user behavior, user groups’ behavior, and applications. Based on this semantic knowledge we are adopting a model where wireless communication is made available on a time and space shifting basis (“context shifting”). Based on this concept, a smart mobile network can plan to use broadband capacity as a function of the current network context, energy availability, type of data, spectrum availability and cost, or to shift the context, for example by rescheduling the time and location of broadband communication. The results are a superior user experience, better use of the spectrum, energy savings, more efficient core network architecture and new business and revenue models.
We are building and experimenting with a network architecture that supports semantic knowledge based context shifting. The extended core architecture will be able to collect and process the knowledge required to dynamically activating context shifting. We are designing, developing and measuring an active network architecture that is using a scalable and reliable network of servers and caches which include a micro server and cashes in the handset. This new architecture manifests in the user perception of a qualitatively and quantitatively faster communication network.
We are building, demonstrating and measuring Content and Semantic-aware Delivery Network (CSDN) that delivers multiple data types (video, ebooks, apps, services, etc.) to a variety of types of handsets. The impact of CSDN is in faster and smarter user interaction as well as in the development and support for new business models.
In order to gather a holistic view of the service provision, which includes network and terminal information, together with user perceived QoE, a novel approach, based on the “Cosem Living Laboratory” (C2L) concept is adopted in this project. The C2L has the overall goal to provide a novel and complete characterization of the various system components concurring in the provision of a given service. It consists of three different performance monitoring tools, designed for gathering relevant information on different aspects of the service provision: a terminal monitoring and load generator software, a network monitoring software and user QoE feedback mechanism.
