    Abstract: CM-00467H IMPROVED SIMULCAST BROADCASTING SYSTEM AND METHOD A simulcast broadcast system wherein two signals (103 an 106) intended for simultaneous broadcast are transmitted from a source site (100) to remote sites (200) discrete from one another. At the remote sites, the two signals are separately processed, including the introduction of appropriate delay (305 and 312), prior to combining them for broadcast in conjunction with other remote sites. One or more monitoring sites (400) can also be provided to monitor reception coherence within the system and to provide operating measurement information to allow automatic control of various simulcast system parameters, including delay.

    Abstract: Un método para transiciones eficientes entre estados operativos en una red de comunicación, comprendiendo el método las etapas de: tener una estación de telefonía móvil en un estado Inactivo; requerir una transferencia de datos; pasar la estación de telefonía móvil del estado Inactivo a un estado Activo; y caracterizado por establecer una conexión entre una Función de Encaminamiento de IP (106) y una Función de Portadora de RF (110) de manera que una conexión existente desde la Función de Encaminamiento de IP (106) a una Función de Control de Localización (108) es modificada de manera que la conexión ahora finaliza en la Función de Portadora de RF (110) sin pasar a través de la Función de Control de Localización (10$); donde la Función de Portadora de RF (110) es: i) un equipo de Sitio de Base y un Selector, ii) un Selector y una o más Estaciones de Emisor - Receptor de Base, iii) un Selector y una o más Estaciones de Base, o iv) uno o más Puntos de Acceso; y la Función de Control de Localización (1Q$) es: i) una Función de Control de Paquetes, o ii) un Controlador de Localización de un Controlador de Punto de Acceso Celular (107).

    Abstract: A wireless communication system that includes an MS that is a member of multiple talkgroups provides for a prioritization of the multiple talkgroups. A database included in the system maintains an MS identifier associated with the MS and maintains multiple talkgroup identifiers in association with the MS identifier, wherein each talkgroup identifier of the multiple talkgroup identifiers corresponds to a talkgroup of the multiple talkgroups. The database further maintains a prioritization associated with at least one talkgroup of the multiple talkgroups. In one embodiment of the invention, the MS may dynamically prioritize the multiple talkgroups to which it belongs. In another embodiment of the present invention, the prioritization may be statically maintained. In still another embodiment of the invention, the system utilizes the maintained prioritizations to determine whether to interrupt the MS when the MS is involved in a multi-party communication session.
