Abstract

EN UN SISTEMA DE RADIOTELEFONO MOVIL CELULAR QUE TIENE UNA PLURALIDAD DE ELEMENTOS QUE PROPORCIONAN COBERTURA RADIOFONICA MEDIANTE UNA PLURALIDAD DE ESTACIONES MOVILES, LA LOCALIZACION DE UNA ESTACION MOVIL RESPECTO A LOS LIMITES DE LOS ELEMENTOS SE IDENTIFICA UTILIZANDO MEDICIONES, REALIZADAS EN LA ESTACION MOVIL O EN LOS ELEMENTOS SELECCIONADOS, DE TRANSMISIONES DESDE LOS ELEMENTOS O DE TRANSMISIONES DESDE LA ESTACION MOVIL. CUANDO SE ENCUENTRA UN ELEMENTO QUE SATISFACE UNA NORMA ESPECIFICADA RESPECTO A UNA CONEXION DE LLAMADA EN PROGRESO SEGUN UN PRIMER CRITERIO DE SEÑALES DE RADIO, SE SELECCIONA UN ELEMENTO CANDIDATO AUTONOMO SEGUN UN SEGUNDO CRITERIO DISTINTO DE SEÑALES DE RADIO. CUANDO NO SE ENCUENTRA NINGUN ELEMENTO QUE SATISFAGA LA NORMA ESPECIFICADA, SE SELECCIONA UN ELEMENTO SEGUN EL PRIMER CRITERIO DE SEÑALES DE RADIO. SE INTENTA LA AUTONOMIA RESPECTO AL ELEMENTO SELECCIONADO SI DICHO ELEMENTO NO SE OCUPA ACTUALMENTE DE LA LLAMADA. MAS PARTICULARMENTE, EL PRIMER CRITERIO DE SEÑALES DE RADIO PUEDE SER FUERZA DE LA SEÑAL Y EL SEGUNDO CRITERIO DE SEÑALES DE RADIO PUEDE SER PERDIDA DE TRAYECTO. CUANDO SE ENCUENTRA UN ELEMENTO QUE SATISFACE EL CRITERIO DE FUERZA DE LA SEÑAL, SE DETERMINA QUE EL ELEMENTO TIENE SUFICIENTE MARGEN DE FUERZA DE LA SEÑAL PARA QUE SE PUEDA UTILIZAR, EN SU LUGAR, EL CRITERIO DE PERDIDA DE TRAYECTO. COMO YA SE HA MENCIONADO ANTES, EL USO DEL CRITERIO DE PERDIDA DE TRAYECTO TIENE LAS VENTAJAS DE CONSERVAR LA POTENCIA, REDUCIR LAS INTERFERENCIAS Y PERMITIR LOS LIMITES DE ELEMENTOS EFICACES PARA CONTINUAR CONECTADO. CUANDO NO SE ENCUENTRA NINGUN ELEMENTO QUE SATISFAGA EL CRITERIO DE FUERZA DE LA SEÑA, SE DETERMINA QUE DICHA LLAMADA ESTA LIMITADA A FUERZA DE LA SEÑAL DE TAL FORMA QUE SE UTILIZA EL CRITERIO DE FUERZA DE LA SEÑAL PARA SELECCIONAR EL ELEMENTO QUE TIENE LA MAYOR FUERZA DE LA SEÑAL.
