Abstract

A conference management system, network, and method for enabling the management of teleconference resources across multiple telecommunications networks that serve multiple conference domains. A disclosed multi-domain conference manager (MDCM) subscribes to a network management platform and for one or more sets of entities. Each set defines a particular combination of i) communications service provider(s) (CSP) and ii) enterprise, in which the combination defines a particular scope of management. When a conference-related event occurs, such as a particular conference involving video endpoints being set up with a unified communications (UC) network, the MDCM can notify a CSP network that is within a same scope of management as the UC network, to report on related events as they occur. The MDCM can then coordinate the connection of resources associated with the multiple domains via a cascaded link between bridging resources that serve the different domains.

Claims

1. A conference management system in a first telecommunications network comprising:

a transmitter that is configured to transmit a first message to a data-processing system, wherein the first message specifies a subscription to events that involve a predetermined set of entities;

the transmitter being further configured to transmit a third message to a third data processing system in a second telecommunications network upon the receipt of the second message by the receiver, wherein the third message specifies to the third data-processing system to monitor for activities related to the first conference, and wherein the first and second telecommunications networks are managed by different service providers; and

a processor that is configured to;

coordinate, based on a fourth message being received from the third data processing system subsequent to the transmitting of the third message and that specifies the first conference, the establishing of a communications link between a first bridging device in the first telecommunications network and a second bridging device in the second telecommunications network, wherein the first and second bridging devices are being used by the first conference, and

determine a second conference identification (ID) in response to the receiving of the second message, wherein the first conference is identified by a first conference ID in the second message, and wherein the second conference ID serves to identify the first conference to the third data-processing system.

2. The conference management system of claim 1, wherein the receiver is further configured to receive a fifth message from the data-processing system, wherein the fifth message specifies that the first conference is ending;

wherein the processor is further configured to coordinate the dropping of the communications link between the first bridging device and the second bridging device, in response to the receiving of the fifth message; and

wherein the transmitter is further configured to transmit;

(i) a sixth message to a session manager, wherein the sixth message specifies that the communications link is to be dropped for the first conference, and

(ii) a seventh message to the third data-processing system, wherein the seventh message specifies to stop monitoring for activities related to the first conference.

3. The conference management system of claim 1 wherein the receiver is further configured to receive a fifth message from the third data-processing system, wherein the fifth message specifies that a participant endpoint has dropped from the first conference;

wherein the processor is further configured to coordinate the dropping of the communications link between the first bridging device and the second bridging device, in response to the participant endpoint being the last endpoint to have been using the second bridging device for the first conference; and

wherein the transmitter is further configured to transmit a sixth message to a session manager, specifying the first conference.

18. The conference management system of claim 1 wherein the transmitter is further configured to transmit a fifth message to a session manager, wherein the fifth message specifies that the communications link is to be established for the first conference.

4. A first telecommunications network comprising:

a conference management system that is configured to;

(i) transmit, to a data-processing system, a first message that specifies a subscription to events that involve a predetermined set of entities,

(ii) receive a second message from the data-processing system specifying that a first conference is starting, wherein the first conference involves the set of entities identified in the first message,

(iii) transmit, upon receiving the second message, a third message to a third data processing system in a second telecommunications network, wherein the third message specifies to the third data-processing system to monitor for activities related to the first conference, and wherein the first and second telecommunications networks are managed by different service providers, and

(iv) establish, upon receiving a fourth message from the third data-processing system wherein the fourth message specifies the first conference, a communications link between a first bridging device in the first telecommunications network and a second bridging device in the second telecommunications network, wherein the

first and second bridging devices are being used by the first conference, and wherein the receiving of the fourth message is subsequent to the transmitting of the third message;

(v) determine a second conference identification (ID) in response to the receiving of the second message, wherein the first conference is identified by a first conference ID in the second message, and wherein the second conference ID serves to identify the first conference to the third data-processing system; and

a network management platform that is configured to;

(i) receive the first message from the conference management system,

(ii) receive, from the first bridging device, an indication that a communication session with a first endpoint has started, and

(iii) transmit the second message to the conference management system, in response to the receiving of (a) the first message and (b) the indication that the communication session has started.

5. The first telecommunications network of claim 4, further comprising a multipoint control unit, wherein the multipoint control unit is configured to provide the functionality of the first bridging device.

6. The first telecommunications network of claim 4, further comprising a session manager that is configured to add the communications link in response to receiving, from the conference management system, a message that specifies the first conference.

7. A method comprising:

transmitting, by a conference management system in a first telecommunications network to a data-processing system, a first message that specifies a subscription to events that involve a predetermined set of entities;

receiving, by the conference management system, a second message from the data processing system specifying that a first conference is starting, wherein the first conference involves the set of entities identified in the first message;
