| Abstract | There has been a rapid increase in the use of mobile telecommunication systems, such as GSM, PDC and PCS, so many people are now using mobile terminal based services. In Japan, the Personal Handy Phone System (PHS) service, which offers a cheaper personal communication service, started in July 1995. Moreover, FPLMTS is being considered as the next generation architecture. As these mobile services become widely used, it will be necessary for a user belonging to one network to be served independently of his location. Therefore, it is important to achieve roaming from one network to another. There are two ways to achieve roaming: one is the HLR (home location register)-based procedure and the other is the VLR (visited location register)-based procedure. In the VLR-based procedure, the visited network can use the data copied from a roaming user's home network, i.e., the VLR. The article discusses VLR-based procedures for roaming and shows which procedure should be applied. Moreover, some message flows are proposed that use the X.500 series recommendation. All of these procedures use the SDF (service data function)-SDF interactions, and it is the agreement between networks that decides the treatment of the copied data. |

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.
