Mobile communication systems make it easy for users to be able to do the communication process even in a mobile condition, one of which allows users to move from a cell area coverage to another cell area coverage, this movement phenomenon is called a handoff. Handoff is the process of diverting traffic channels automatically on a mobile station (MS) that is being used to communicate without termination. This paper analyzes the service quality improvement of the hard handover mobile communication network model from two to three base stations (BS) on the path loss parameter. Service quality parameters to be considered are the improvement of signal degradation and delay handover from two BS to three BS against the fixed and adaptive hysteresis methods.
