The present invention provides a method for communicating signaling messages associated with a communication system whereby a network within the communications system is responsible for setting up a signaling path between users of the communication system. However, once that signaling path is established by the network, the users may communicate with each other whereby the network is not needed to pass data between the users thereby substantially decreasing demand on the network and freeing it for other system functions.

Method for communicating signaling messages through a broadband network

A multicast message is transmitted from an originating subscriber unit (,, FIG.,) through a network of satellite communications nodes (,, and,) to a plurality of receiving subscriber units (,, and,). Each message is distributed through the network of satellite communications nodes (,, and,) and replicated at the node nearest to the receiving subscriber unit. Receiving subscriber units (,, and,) are mapped into geographic cells which allows a single multicast transmission to be transmitted from the satellite communications node to those subscriber units within the same geographic cell. Multicast groups and membership rules are established by the originating subscriber unit (,) through a service provider (,). A multicast session manager (,) manages the multicast session.

Method and system for multicast using a satellite network

Methods (,, and,) and a multi-layer service management system (,) enable mutilayer service management in a global network environment in a communication system (,) which includes a core network (,) and multiple Distributed Virtual Network Segments (DVNSs) (,). The system (,) includes a network service manager (,) capable of managing a set of services for operating the core network, DVNS service managers (DVNSMs) (,) residing within a core side (,) and a product side (,) of each item of DVNS equipment (,) for managing a first and second set of services associated with the DVNS and also a set of value added services (,) provided through the DVNS equipment (,), and a processor/server,residing within customer premises equipment (CPE) (,) for enabling provision of value added services to the CPE. Methods (,, and,) enable management of services using the service management system (,) by distributing service management across the layers of the network architecture (,).

Method and system for multilayer service management

A message processing center (,) is used in a global message delivery system. Message processing center (,) uses at least one GEO satellite (,) and at least one Non-GEO satellite (,) to delivers messages (pages) to a number of ground stations (,) located at various locations on the surface of the earth. Message processing center (,) determines loading for at least one GEO satellite (,) and at least one Non-GEO satellite (,). Message processing center (,) determines available capacity for at least one GEO satellite (,) and at least one Non-GEO satellite (,). Message processing center (,) uses a number of criteria to optimize the delivery of the message data.
