In this age of wireless telecommunications, it is expected from the telecom service providers that the quality of services is the best; but unfortunately, it is not so and in India the telecom sector is struggling with a menace called Call Drops. Most of the operators in India do not meet the benchmark set by the TRAI for call drops. So, keeping in mind the Indian context of the problem, in this paper, the overall condition of call drops has been reviewed and possible ways to minimize the phenomena of call drops- Cell Splitting and Sectoring, Dynamic channel allocation, Hybrid channel allocation. Also, mathematical proof of relevance of these methods has been provided through Erlang B Formula and various other methods of proving used in other scientific pieces of work have been discussed such as Poisson Probability Function with a discrete variable. The data collected from various resources shows the gravity of the problem. Cell splitting and sectoring methods result in improvised soft handover mechanisms which in turn decrease the rate of call drops. This paper provides a brief but sufficed introduction to the term of call drops and also proposes some simple but efficient ways to cope this menace.

Keywords- Call drops, Call drop rate, Cell splitting, Sectoring, Hand-offs/hand-over.
