Handover Initiation Control Techniques in Mobile Cellular Systems
Brahmjit Singh, Shakti Kumar, K.K. Aggarwal · IETE Technical Review · 2003
This paper presents the handover process in terms of radio propagation issues. It covers the propagation phenomenon in mobile radio communications and fundamentals of handover process. It reviews different approaches and criteria based on received signal strength to detect the need for a handover. Recently developed initiation control techniques based on radio link measurements are studied. Adaptive and multicriteria handover algorithms are introduced. Mathematical models for performance evaluation of handover initiation control techniques are critically analyzed. Finally, key issues and future challenges in context with third generation wireless systems have been identified.
