Abstract

Un método para establecer la histéresis apropiada de las células de una red de telecomunicaciones inalámbricas a fin de reducir el índice de traspasos delservicio oscilantes que surge de un traspaso del servicio de estacion movil de rutina de una célula de origen a una célula adyacente. El método incluyemedir la potencia de senal recibida en la célula de origen y la potencia de senal recibida de por lo menos una célula adyacente. La histéresis secalcula aplicando una operacion estadística, tal como una desviacion estándar, a por lo menos una de las potencias de senales recibidas. En forma alternativa,el cálculo de histéresis puede incluir el índice de oscilacion de los traspasos del servicio. El valor de histéresis calculado se puede presentar al operador alos efectos de ajuste manual o se puede ingresar en las células autoconfigurantes a los efectos del ajuste dinámico de los niveles de histéresis con elobjeto de mejorar el rendimiento operativo de la red.
