Abstract

Se describe un metodo para conmutar una sesion de videoconferencias que actualmente se esta presentando de unidifusion a multidifusion. El metodo incluye los pasos de enviar una invitacion del servidor a una parte adicional (2620), asignar una direccion de Protocolo Internet (IP) de multidifusion comun y transmitir la direccion de IP de multidifusion comun al participante actual en la sesion de videoconferencia y una parte adicional que sera agregada a la sesion de video conferencia (2640), transmitir un mensaje de IGMP a la red del participante actual y la parte adicional (2650), y alojar la sesion de videoconferencia en la direccion de multidifusion (2660).
