Abstract

A multimedia conference reservation controller and reservation acceptance system includes a database of all presently reserved resources on each MMS controlled by the reservation controller which includes an identification of each resource together with the starting time and ending time of the reservation.
The acceptance system is designed to accept a reservation query which includes a list of required resources, where flexible resourcesgb981594sidered desirable resources, but not absolutely necessary resources. In response to a reservation query involving a single MMS, the acceptance system accesses the database and builds a list of resources together with the times during which those resources are already reserved. This list is used to create a Resource Availability Matrix which is then analyzed and a list of time periods is generated during which the requested resources are available. In addition, the matrix analysis also indicates exactly which resources must be used to satisfy the request for each time period. In response to a reservation query involving two MMS units (202), the acceptance system builds two resource availability matrices (236), one for each MMS which are analyzed to generate a list indicating the time periods during which the conference can be reserved and the resources which must be used.
