Abstract:
In a network based on AAL Type 2 technology, an arrangement for determining whether an AAL Type 2 connection can be established through nodes of the network, the network being divided into a predetermined number of resource domains (RD_1-RD_4), each comprising a predetermined number of the nodes (MSC_1-MSC_4) of the network, one (MSC_1-MSC_4) of the nodes in each resource domain (RD_1-RD_4) hosting a prediction connection admission control unit (p-CAC_1-p-CAC_4), comprising information about resources available for establishing AAL Type 2 connections through its own resource domain (RD_1-RD_4), and each prediction connection admission control unit (p-CAC_1-p-CAC_4), upon a request for an AAL Type 2 connection, being adapted to decide whether or not an AAL Type 2 connection can be established through its own resource domain, characterized inthat each prediction connection admission control unit (p-CAC_1-p-CAC_4) comprises information about resources available for establishing AAL Type 2 connections through the other resource domains (RD_1-RD_4) of the network, and that each prediction connection admission control unit (p-CAC_1-p-CAC_4), upon a request for an AAL Type 2 connection, is adapted to predict, if the requested connection is to be extended to other resource domains, the outcome of decisions by said other prediction connection admission control units as to whether AAL Type 2 connections can be established through their resource domains.
