| Abstract | SFA management is an essential element in the WiMAX network architecture. However, there are some issues, which are the abruptions between the authenticator and the ASFA and between the anchor GW and the SSFA. The abruptions result from the mobility management in WiMAX network architecture and bring on that service flow service provided to mobile users can’t be accomplished. Network exit may take place because the incorrect communication from the abruptions. The issues are figured out by the ASFA relocation algorithm and the SSFA relocation algorithm presented in the paper. The algorithms proposed can implement the normal communication between the ASFA and the SSFA. And mobile users can obtain the anticipant service flow. Therefore, the network exit and the states mismatch can be avoided. The proposed scheme can be implemented through minimally modifying the existing Mobile-WiMAX specification. Furthermore, after the relocation of SSFA follows the change of the anchor point in the CSN mobility management, the ASFA is not conscious of the location movement of the SSFA. In this paper, the context transfer is applied for notifying the current location of the SSFA to the ASFA. |

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.
