Abstract

Un equipo de usuario (EU) en un sistema comunicación celular rastrea celdas vecinas realizando periódicamente un proceso de medición de señal y realizando periódicamente un proceso de seguimiento de señal. Las celdas vecinas se clasifican de acuerdo con el nivel de señal medido, y el número de celdas que se rastrean es variable, y se basa en la estabilidad del entorno de radio en el cual el EU está funcionando. La velocidad a la cual una celda vecina cambia del estado de no ser la celda vecina más fuerte al estado de ser una es un indicador de la estabilidad del entorno. Cuando una celda vecina se convierte recientemente en la celda vecina de ranking más fuerte, el ranking que esa celda vecina tuvo un período de tiempo predeterminado atrás puede ser utilizado como un indicador de la cantidad de celdas vecinas a rastrear. El período de tiempo predeterminado puede ser una cantidad promedio de tiempo que toma rastrear una celda vecina.
