Abstract
Abstract A communication system is provided for transferring broadband multimedia data through a network. The system includes network terminals, a transmission backbone, and a call set-up server. The call set-up server controls call handling and connection handling or channel allocation. Channel allocation is handled separately from call control, enabling upgrading of connection handling hardware and software without affecting the rest of the system.

A method of a setting up a call in a communications network from a transmitting point to a destination point, the method comprising the steps of: ordering the call to be transferred from the transmitting point, transferring the call from the transmitting point to a transmitting access part, for determining how the call should be represented and selecting a service, transferring the call, which includes a call portion representing the actual data to be transferred and a connection portion representing connection points, from the transmitting access part to a call handling portion, handling the call portion in the call handling portion, including performing the selected service, and transferring the connection portion to a connection handling portion, reserving a connection between the connection points represented by the connection portion in the connection handling portion, transferring the call portion from the call handling portion to a destination access part, interpreting how the call is represented and the service that has been selected in the destination access part, transferring the call to the destination point, answering the call in the destination point, transferring answered call information from the destination point to the destination access part, for determining how the answered call information should be represented, transferring the answered call information, which includes an answered call data portion representing the actual answer data to be transferred and an answered connection portion representing reserved connection points, from the destination access part to a call handling portion, handling the answered call data portion in the call handling portion, and transferring the answered connection portion to the connection handling portion, setting up a connection between the reserved connection points represented by the answered connection portion in the connection handling portion, transferring the answered call data portion from the call handling portion to the transmitting access part, interpreting how the answered call information is represented in the transmitting access part, and transferring the answered call information to the transmitting point.
Claim 3
Dependent Claim
39 words
The method of claim 1, wherein since the call handling portion handles the call portion and the connection handling portion reserves and sets up the connection, upgrading of the connection handling portion can be performed without affecting call handling.
Claim 4
Dependent Claim
11 words
The method of claim 1, wherein the data comprises multimedia data.
Claim 5
Dependent Claim
315 words
A call set-up server for setting up a call in a communication network from a transmitting point to a destination point, the call set-up server comprising: a transmitting access part for receiving the call from the transmitting point, determining how the call should be represented, and selecting a service; a call handling portion for receiving the call from the transmitting access part, wherein the call includes a call portion representing the actual data to be transferred and a connection portion representing connection points, and the call handling portion handles the call portion, including performing the selected service; a connection handling portion for receiving the connection handling portion of the call from the call handling portion and reserving the connection between the connection points represented by the connection portion; a destination access part for receiving the call portion from the call handling portion and interpreting how the call is represented and the service that has been selected; wherein the call is transferred to the destination point, the call is answered in the destination point, answered call information, which includes an answered call data portion representing the actual answer data to be transferred and an answered connection portion representing reserved connection points, is transferred from the destination point to the destination access part which determines how the answered call information should be represented, the answered call information is transferred from the destination access part to the call handling portion, the call handling portion handles the answered call data portion and transfers the answered connection portion to the connection handling portion, the connection handling portion sets up a connection between the reserved connection points represented by the answered connection portion, the call handling portion transfers the answered call data portion to the transmitting access part, the transmitting access part interprets how the answered call information is represented, and the answered call information is transferred to the transmitting point.
Claim 6
Dependent Claim
315 words
