Abstract

LA INVENCION PERMITE LA INTRODUCCION DE UN CODEC (108, 128) DE ACUERDO CON UN NUEVO METODO DE CODIFICACION DE VOZ EN UN TRANSCEPTOR DE TRANSMISION DE VOZ (100) DE UN SISTEMA DE TELECOMUNICACIONES DIGITAL, DE FORMA QUE RESULTA POSIBLE UTILIZAR UN NUEVO CODEC (108, 128) Y UN CODEC ANTIGUO (106, 126) EN PARALELO EN EL SISTEMA. UN CODEC SE SELECCIONA IMPLEMENTANDO UN PROCEDIMIENTO DE INTERCAMBIO DE PROTOCOLO DE ACUERDO CON LA INVENCION ENTRE LOS TRANSCEPTORES (100, 100 ). LA INVENCION SE BASA EN EL INTERCAMBIO DE PROTOCOLO EN EL QUE UN METODO DE CODIFICACION DE VOZ IMPLEMENTADO EN TODOS LOS TRANSCEPTORES (100, 100 ) Y UTILIZADO PREVIAMENTE EN EL SISTEMA DE TELECOMUNICACIONES AFECTADO, SE UTILIZA EN PRIMER LUGAR AL COMIENZO DE CADA CONEXION. AL COMIENZO DE UNA LLAMADA TELEFONICA Y DESPUES DE LA TRANSFERENCIA, EL METODO COMPRUEBA SI AMBAS PARTES (100, 100 ) PUEDEN UTILIZAR TAMBIEN LA NUEVA CODIFICACION DE VOZ. LOS MENSAJES DE INTERCAMBIO DE PROTOCOLO SE HAN SELECCIONADO DE FORMA QUE SU EFECTO SOBRE LA CALIDAD DE LA VOZ ES MINIMA Y DE FORMA QUE LA PROBABILIDAD DE IDENTIFICAR LOS MENSAJES ES MAXIMA.
