| Abstract | A personal communication services (PCS) network consists of a fixed wireline network component and a number of mobile terminals. To conserve wireless bandwidth, mobile terminals are not permanently connected to the wireline network. A mobile terminal is completely detached from the network when it is idle and it is assigned a channel only if necessary. Therefore, a method is needed for locating the mobile terminal when an incoming call arrives. Current PCS networks rely on a paging scheme to locate a mobile terminal. However, when the network coverage area is large, the paging cost is high. To reduce the paging cost, a location update procedure is employed such that a mobile terminal periodically reports its location to the network. Location updates consume wireless bandwidth and impose additional overhead to the wireless network. However, the information obtained during location update allows the network to limit the size of the paging area and, thus, reduces the paging overhead. This paper describes a location update mechanism which reduces the cost for location update and paging based on the mobility history of the mobile terminal. Other system parameters such as the mobility and call arrival rates as well as the costs associated with location update and paging are also considered. |

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.
