Abstract

UN SISTEMA DE ASIGNACION DE CANAL PROPORCIONA ASIGNACIONES DE CANALES PARA HACER EFECTIVO EL USO DE UN ESPECTRO DE FRECUENCIA UTIL, MEDIANTE LA ASIGNACION DE UN CANAL EN UN TIEMPO HASTA QUE TODOS LOS CANALES EN EL ESPECTRO DE FRECUENCIA SUSCRITA SON UTILIZADOS. UN PASO DE PREDISTRIBUCION ASIGNA CANALES ESPECIFICOS PARA CELULAS FIJAS Y ESTAS ASIGNACIONES SON DETENIDAS CONTRA LOS CONSTREÑIMIENTOS DEL SISTEMA DE ENTRADA INICIAL. ENTONCES LOS CANALES SOBRANTES SON ASIGNADOS UNO EN CADA TIEMPO A LAS CELULAS DE ACUERDO CON CONSTREÑIMIENTOS DE EJECUCION DE UN SISTEMA DEFINIDO Y CON EL NUMERO DE CANALES REQUERIDOS POR CADA CELULA. CADA CELULA ESTA DEFINIDA POR SUS FUENTES LOGICAS. LA CARGA DE TRAFICO PARA CADA FUENTE LOGICA ESTA DEFINIDA DE ACUERDO CON FACTORES SELECCIONADOS QUE PUEDEN INCLUIR: COSTES DE LLAMADAS, COSTES DE BLOQUEO, UMBRALES DE TRANSMISION, ACCESO A LOS UMBRALES, COSTES BAJOS DE LLAMADAS, ETC. DADOS ESTOS FACTORES EL NUMERO DE CANALES REQUERIDOS POR CADA FUENTE LOGICA PUEDE SER DERIVADO Y EL CONSUMO DEL SISTEMA DE ASIGNACION DE CANALES. UN NIVEL DE INTERFERENCIA ES DETERMINADO PARA CADA FUENTE LOGICA, CAUSADO POR CADA OTRA FUENTE LOGICA POR MEDIO DE UNA COMPUTADORA DE MATRIZ DE SEÑAL (410). LOS FACTORES INVOLUCRADOS EN ESTA DETERMINACION INCLUYEN EL TERRENO GEOGRAFICO, LAS PROPIEDADES DE TRANSMISION DE LA ANTENA, LA POTENCIA DE TRANSMISION Y LA LOCALIZACION DE LAS CELULAS INDIVIDUALES. UNA MATRIZ DE SEÑAL DE INTERFERENCIA SE DESARROLLA A PARTIR DE ESTA INFORMACION. LOS CANALES INDIVIDUALES SON AHORA ASIGNADOS (420, 440) A LAS FUENTES LOGICAS BASADAS SOBRE LA INFORMACION DESARROLLADA, INCLUYENDO EL NUMERO DE CANALES NECESITADOS PARA CADA FUENTE LOGICA, LA MATRIZ DE SEÑAL DE INTERFERENCIA Y OTROS CONSTREÑIMIENTOS DEL SISTEMA (425).
