Abstract: A method and system for generating real-time announcements in a digital packet-switched telecommunications network includes an announcement server for sensing a predetermined trigger event and generating a predetermined announcement for insertion into a data stream. A packet-based network then transmits the packetized announcement along with the current data stream for receipt by the destination. The announcement is then processed by the appropriate processing device, such as a Base Station Controller or a wireless handset, immediately upon receipt of the packetized announcement so that it can be generated in real-time.

Abstract: Information packets are routed through a distributed routing network by determining a forwarding equivalency class (FEC) for each subscriber unit accessing the network. The FEC to which each subscriber unit belongs is based on the point at which the subscriber unit accesses the network. The forwarding equivalency class for each subscriber unit is updated if the subscriber unit accesses the network at a different point. Information packets are routed from a distribution point by determining the next point connected to the distribution point based on the forwarding equivalency class for the destination subscriber unit specified in the packet.
