Abstract
A channel reservation control system which reserves data channels in an appropriate manner to ensure the subsequent call set-up operations in automatic call distribution services. A channel allocation unit determines how many data channels should be reserved for a specific group of subscribers who may wish to use such reserved bandwidth. Then, a reservation request transmission unit makes a provisional reservation for as many data channels as determined by the channel allocation unit, and transmits a reservation request message to initiate the reservation of those data channels. Upon receipt of this reservation request message, a recipient-side reservation unit establishes channel reservation on the side of call recipients by securing the requested data channels for exclusive use by the specific group of subscribers. Then, a channel reservation acknowledgment unit returns a channel reservation acknowledgment message to notify the originator-side reservation unit about the data channels reserved by the recipient-side reservation unit. On the side of call originators, an originator-side reservation unit establishes the channel reservation by securing the data channels for exclusive use by the specific group of subscribers, in response to the channel reservation acknowledgment message.
