Abstract

Un sistema de comunicaciones de datos es sobrepuesto sobre un sistema troncal de radio, basado en voces. Los paquetes de datos digitales se transmiten sobre los canales de radio disponibles, haciendo así posible la comunicación de datos entre un sistema de envío huésped y unidades móviles y una estación base en el sistema troncal de radio. Los canales de radio asociados con los grupos troncales de canal son accedidos, cuando están disponibles, por un controlador de comunicaciones. El controlador de comunicaciones se configura para comunicarse con varias unidades móviles del sistema troncal de radio sobre los canales de radio disponibles a través de múltiples enlaces de comunicaciones de radio. Estos canales de radio son vigilados para detectar cuando ellos están presentemente sin usar, para la transmisión de voz y así accesibles para sobreponer datos. En particular, cuando el sistema de sobreposición de datos detecta que cesa la transmisión de la información analógica de voces en un canal de radio particular, la asociación del grupo de canales troncales de ese canal de radio particular se hace interrumpir desde el grupo de voces al grupo de datos. Los paquetes de datos son luego transferidos sobre el canal de radio disponible.
