Claim 11

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.

Claim 12

A reservation system according to claim 9, wherein: said second reservation controller has means for determining whether the second MCU coupled to said second reservation controller has sufficient resources to meet its portion of said reservation request, and means for forwarding a resource determination to said first reservation controller.

Claim 13

A reservation system according to claim 9, wherein: said second reservation controller includes means for sending information regarding resources of said second MCU to said first reservation controller.

Claim 14

A reservation system according to claim 10, wherein: said second reservation controller has fourth interface means for interfacing with a data transport profile of another user wishing to make a reservation.

Claim 15

A reservation system according to claim 12, wherein: said second reservation controller further includes means for establishing with multipoint connection a second reservation domain with a second reservation request channel, and second conference control means associated with said second reservation domain and establishing a second ongoing reservation conference.

Claim 16

A reservation system according to claim 9, wherein: said second reservation controller further includes means for establishing with multipoint connection a second reservation domain with a second reservation request channel, and second conference control means associated with said second reservation domain and establishing a second ongoing reservation conference.

Claim 17

A reservation system according to claim 14, further comprising: a third reservation controller coupled to at least one of said first and second reservation domains and having, second means for joining at least one of said first and second ongoing reservation conferences and for coupling to at least one of said first and second reservation request channels, interface means for coupling said third reservation controller to a third MCU of the plurality of MCUs the resources of which is controlled by said third reservation controller, and third reservation application protocol entity means including third means for receiving a reservation request placed on one of said first and second reservation request channels.
