Communications system with special channel
View Patent ↗The invention relates to a communication system which operates in the asynchronous transfer mode (ATM) and which comprises several nodes which form a network and are partly coupled to one another and to terminals, and which each comprise a switch and a control software at least for controlling the relevant coupling field and for the signaling. At least one object of the control software contains detection points in certain states. An object for event handling of the control software is provided for further processing when a detection point is reached. The object for event handling receives data via a special channel from at least one terminal or from another node.
1. A communications system operating in asynchronous transfer mode, comprising:
a plurality of nodes, wherein selected nodes are connected, each node having a switch and control software for controlling the switch, the control software having a plurality of objects where each object performs a particular function of the control software, including at least one object for event handling;
a special channel facilitating communications between an object of the control software and each of the nodes and terminals, wherein said communications includes receipt of data by the object for event handling from at least one of said terminal- or said other nodes.
2. The communications system of claim 1 , wherein at least one object of the control software, which is responsible for signaling and which can be either represented as or described by a state machine, which comprises detection points in certain states.
3. The communications system of claim 1 , wherein the special channel includes the communication of information via a certain cell type.
4. The communications system of claim 1 , wherein after the switch-over of the processing of a first object by the control software via a detection point, the object for event handling receives information via the special channel and/or switches over to the processing of the first or of a second object.
5. A node in a communications system operating in the asynchronous transfer mode, which forms a network with several other nodes and is connected to at least one other node, the node comprising:
a switch;
control software at least for controlling the switch, the control software comprising a plurality of objects where each object performs a particular function of the control software, including at least one object for event handling; and
a special channel for communications between an object of the control software and selected nodes and/or a terminal, where said communications includes receipt of data by the object for event handling from at least one terminal or: one of the selected nodes.
