Multimedia multipoint telecommunications reservation systems
First Claim
1. A reservation controller for controlling access to at least one telecommunications multimedia multipoint control unit (MCU), comprising:
- a) means complying substantially with ITU-T T.122 multipoint communications service (MCS) protocol for establishing with multipoint connection a reservation domain with a reservation request channel;
b) conference control means associated with said reservation domain and establishing an ongoing reservation conference;
c) first interface means complying substantially with at least a portion of ITU-T T.123 network specific transport protocol for interfacing with a data transport profile of a user who wishes to make a reservation;
d) second interface means for coupling said reservation controller to the at least one MCU;
e) reservation application protocol entity means including means for receiving a reservation request placed on said reservation request channel, and means for determining whether the at least one MCU coupled to said reservation controller has sufficient resources to meet said reservation request, whereinthe user makes said reservation request by attaching to said reservation domain, joining said ongoing reservation conference, and placing said reservation request on said reservation request channel.

Abstract
Reservation controllers and reservation systems for reservation of access to multimedia multipoint telecommunications servers (MCUs) are provided. The reservation controller establishes a reservation domain having a reservation request channel on which reservation applications may be taken. An ongoing reservation conference is associated with the reservation domain. The reservation domain is preferably established within the ITU-T T.120 standard series requirements, with multipoint connection under T.122/T.125, and interface to profiles such as ISDN, TCP/IP, X.25, ATM, Ethernet, etc., under T.123. A user makes reservations for MCU resources by knowing the address of the reservation domain, attaching himself to the reservation domain, joining the reservation conference via establishing one or more transport connections, and sending the reservation request onto the reservation request channel. All reservation requests forwarded onto the reservation request channel are received and acted upon by the reservation controller. Reservation systems utilizing a plurality of reservation controllers are also disclosed, where the reservation controllers are part of the same domain, are arranged in multiple domains on a single level, or are arranged in hierarchical domains. Where more than one reservation domain is established, same-level or hierarchical level bridges are established.

9. A reservation system which controls access to a plurality of telecommunications multimedia multipoint control units (MCUs), comprising:
-
a) a first reservation controller having means for establishing with multipoint connection a first reservation domain with a first reservation request channel, conference control means associated with said first reservation domain and establishing a first ongoing reservation conference, first interface means for interfacing with a data transport profile of a user wishing to make a reservation, second interface means for coupling said first reservation controller to a first MCU of the plurality of MCUs the resources of which is controlled by said first reservation controller, and first reservation application protocol entity means including first means for receiving a reservation request placed on said first reservation request channel, and means for determining whether the first MCU coupled to said first reservation controller has sufficient resources to meet its portion of said reservation request; b) a second reservation controller having means for joining said first ongoing reservation conference and for coupling to said first reservation request channel, wherein reservation requests of a user placed on said first reservation request channel are available to said second reservation controller when said second reservation controller is joined to said first ongoing reservation conference, third interface means for coupling said second reservation controller to a second MCU of the plurality of MCUs the resources of which is controlled by said second reservation controller, and second reservation application protocol entity means including second means for receiving a reservation request placed on said reservation request channel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
