Abstract

UN SISTEMA DE TRANSFERENCIA DONDE LAS SOLICITUDES DE TRANSFERENCIA NO SOLO LAS INICIA UNA ESTACION BASE SIRVIENTE O DOMESTICA, SINO TAMBIEN UNA ESTACION BASE VECINA. AL IGUAL QUE EN LOS SISTEMAS DE TRANSFERENCIA CONVENCIONALES, UNA ESTACION BASE SIRVIENTE PUEDE INICIAR UNA SOLICITUD DE TRANSFERENCIA CUANDO LA INTENSIDAD DE LA SEÑAL DE UNA DE SUS ESTACIONES MOVILES CAE POR DEBAJO DE UN UMBRAL PREDETERMINADO. ADEMAS, LAS ESTACIONES BASE VECINAS CONTROLAN LA INTENSIDAD DE LA SEÑAL DE LAS ESTACIONES MOVILES VECINAS Y SOLICITAN QUE UNA ESTACION MOVIL VECINA SEA TRANSFERIDA CUANDO LA INTENSIDAD DE LA SEÑAL ALCANCE UN NIVEL PREDETERMINADO. ASI, LA SOLICITUD DE TRANSFERENCIA PUEDE PROCEDER DE LA ESTACION BASE SIRVIENTE DEBIDO A UNA CONEXION DE LLAMADA DEFICIENTE O PROCEDER DE UNA ESTACION BASE VECINA DEBIDO A UNA POSIBLE CONEXION DE LLAMADA POTENTE.
