Abstract

Se describe un método y un aparato para cambiar automáticamente funciones asociadas con una radio de guía a otra radio en un canal. El método incluye recibir (410), desde una radio de guía por al menos otra radio que opera en un canal, una señal de tiempo asociada mediante al menos un mensaje de tiempo de control. Otras radios utilizan la señal de tiempo para sincronizar transmisiones hechas en el canal. El método también incluye recibir (420), por las otras radios, una indicación de que la radio de guía ya no puede proporcionar mensajes de tiempo de control. El método además incluye mantener (430), por cada radio en el canal, valores para diversos elementos asociados con radios que operan en el canal y seleccionar (440) una nueva radio de guía de las otras radios con base en las prioridades de los diversos elementos.
