| Abstract | With the convergence of the Internet and the mobile communications world, Internet-based services may become available on any user device. In order to make efficient use of such a ubiquitous environment the user demands to access his personalized services from any place, anytime and on any device regardless of the type of access network. In particular, we consider the situation that a user transfers a running session between devices. We refer to this as session mobility. Providing such ubiquitous services transparently to the user, is not only challenging from a networking point of view but also poses severe requirements on the management operations and in particular accounting needed for a commercial service rollout. We describe an accounting architecture for session mobility. It allows the network operators to determine, collect and evaluate data on service usage when users transfer their ongoing communication session(s) from one device to another or a set of devices within its domain or across multiple operators' environments. In particular, we describe the interactions required between the signaling protocol and the accounting protocol in support of session mobility. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
