<p>A communications network simultaneously transmits a single message to a number of recipients. This is called a 'multicast' transmission. The communications network should have a recipient list database (1302) to receive a list of recipient addresses, a message database (1304) to receive and store the message, and a message delivery system (1306) to send the message to a number of recipients. The communications network may be adapted to collect acknowledgements or responses to a multicast message. If so, the communications network should have a calling record (1308) for storing message delivery information, a response record (1310) for receiving and storing recipient response information, a response processor (1312) for processing the response information, and a response delivery system (1314) for delivering the processed response. The multicast capability may be integrated with other communications network services, such as Personal Location Service, Personal Communications Internetworking, call blocking, etc.</p> |
