Abstract :
In the mobile environment, the dropped calls can result from shadowing and rapid signal loss. We present and implement a transparent reconnect procedure (TRP) which is an efficient algorithm that can be adapted easily for the benefit of decreased dropped calls. In the simulation of a typical cellular system, it is shown that the fewer dropped calls using TRP compared to the conventional procedure. This benefit comes at the expense of a slight increase (<%1) in blocked call percentage
