Many mechanisms implemented to fulfill the growing demands for better mobile communication service. The ever growing discussions about the limitation of signaling and switching are almost solved by various algorithms and methods. The most effective method is handover; the mechanism transfers an on-going call from one cell to another as user moves through coverage. Handover became more efficient with increasing use and demands in communication i.e. multimedia application and web-based application etc. With growing generations of networks there are introduced various algorithms for better Quality of Service (QoS) and decrement of call dropping probability.
