| Abstract | In LTE Trunking communication system, users move in terms of group to dispatch and execute tasks. eNodeB may turn into hotspot in a short time. In order to balance the system load and reduce call blocking probability, the paper propose a load balancing algorithm with OFDMA technology based on two typical services. When origin eNodeB initiates load balancing mechanism with adjacent eNodeBs, the point to multipoint service carrying (group call service) may be switched to target eNodeB to share broadcast channel because users belonging to one group receive the same data. If group call service carrying handover is not available then the point to point service carrying is to be switched to target eNodeB according to maximum $SLP_{eNodeB}(t).$ Simulation results show that, the proposed algorithm could balance the system load, and reduce call algorithm could balance the system load, and reduce call blocking probability and improve system capacity efficiently at the same time. |

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.
