  • Method and arrangement for controlling alternative routing of traffic in a circuit-switched network
    Patent number: 6606380
    Abstract: The method comprises receiving call signalling in a node and routing the call in accordance with the call signalling. If congestion is met, it is decided whether an alternative routing is allowed in dependence on parameters associated with the call and the node and the call is routed in accordance with such allowed alternative routing. If congestion is met again or no alternative is allowed, it is decided if the call should be released or subject to crankback, dependent on parameters associated with said call and node. By receiving indicators with the call signalling, indicating the types of alternative routing performed in preceding nodes and using said indicators as parameters for the above decisions, and updating said indicators for each call whenever alternative routing is performed for said call, the alternative routing can be controlled in an improved and simple manner. Several types of alternative routing may be available in the nodes.
