Abstract

A message is multicast to recipients by correlating the message at a management system to agents, each agent being responsible for a set of the recipients, and by conveying the message over a network to the correlated agents for transmission to the recipients. The management system maintains recipient lists wherein each list is associated with one or more agents, each agent maintaining a portion of its associated lists. The management system chooses a single recipient list and conveys an indication of the list to its associated agents. Each notified agent accesses the indicated list and sends the message to the listed recipients. In a further embodiment, an independent management system interfaces a plurality of management systems, each with a set of agents. The independent management system chooses a recipient list, the list being associated with a management system and its agents, and conveys the message based on the chosen list.

12. A method for multicasting a message to subscribers of a telephony system wherein the telephony system comprises a plurality of end-office switches serving the subscribers, said method comprising:

receiving at a management system an indication,

using the indication to choose from among a plurality of master recipient lists one master recipient list,

determining from among a plurality of agents which agents are associated with the chosen master recipient list,

conveying a multicast request to one or more of the determined agents wherein the multicast request comprises an indication of the chosen master recipient list, and

wherein each multicast request causes an agent to access a list that is associated with the master recipient list indicted in the multicast request and to send the message to the subscribers specified within the accessed list.

13. The method of claim 12 wherein each agent receiving the multicast request further conveys the multicast request to one or more of the determined agents.

14. The method of claim 12 further comprising prior to the receiving step the steps of:

receiving a plurality of subscriber information, and

using the plurality of subscriber information to create the plurality of master recipient lists.

15. A method for multicasting a message to a plurality of recipients wherein each recipient is associated with a communications network, said method comprising:

receiving at an agent a multicast request, wherein a management system generated the multicast request by choosing from among a plurality of master recipient lists a single master recipient list and by determining that the agent is associated with the single master recipient list, and wherein the multicast request comprises an indication of the single master recipient list,

accessing a list associated with the indicated single master recipient list, and

establishing communications with recipients specified in the accessed list to deliver the message.

16. The method of claim 15 wherein each entry of the accessed list comprises a priority indicator and wherein the establishing step further comprises the step of using the priority indicator to establish the communications and deliver the message to the specified recipients in a plurality of call waves.

17. The method of claim 15 wherein each entry of the accessed list comprises geographical coordinates and wherein the establishing step further comprises the steps of:

using the geographical coordinates to determine a subset of the recipients specified in the accessed list, and
