Abstract | Cellular operators are facing difficulties in supporting a huge increment in the subscribers due to spectrum and equipment restrictions. There have been many proposals in the area of increasing call carrying capacity such as Reuse Partitioning and Directed Retry. However, such action increases the size of the network and results to higher installation, maintenance and optimization costs for the cellular operator. In this paper we are proposing a cost effective new channel reservation scheme based on subscribers' average call duration which can be implemented in any existing cell. A cell has been considered which has very few allocated channels and is also unable to execute load balancing methods such as channel borrowing, call transfer etc. Also, the average call duration of the subscribers are taken in the range of 0 – 40 minutes. A cell with such restrictions may have higher blocking probability, but the results show that the proposed channel allocation scheme can effectively reduce the overall call-blocking for such cell. This scheme is particularly useful in a cell having heavy traffic with mostly business calls. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
