| Abstract | Even though Evolved Packet System (EPS) features flat-IP architecture, it is essentially a connection oriented system and establishes logical bearers between the User Equipment (UE) and the core network entities for any user data transmission. EPS was designed assuming high speed real-time bulk multimedia data transfer; so initial cost of bearer setup signaling for user plane data is justified. However, this basic assumption is changed due to very small and infrequent background data transfer by the smartphone's always-on applications most of the time when smartphone is not in active use. To transmit this background data, UE incurs frequent idle to connected state transitions and require costly disproportionate signaling overhead for EPS bearer and Radio Resource Control (RRC) connection setup/release procedure. This paper presents a connectionless transmission (CLT) scheme for efficient exchange of background data without establishing the EPS bearer and RRC connection. In the proposed CLT scheme, the data packets are made self-sustainable by carrying routing information in the packet's header. These self-sustained packets are carried through modified Random Access Channel (RACH) procedure between the UE and the eNodeB. Further, another novel aspect of the CLT scheme is to establish common user plane bearers between the radio access network and packet gateways in the core network, to forward self-sustain data packets using the routing information. Our simulation results show CLT scheme reduces the signaling overhead significantly compared to the traditional connection oriented transmission. |

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.
