A RESOURCE MODEL AND ARCHITECTURE FOR A CONNECTION HANDLING SYSTEM

摘要

A resource model for modelling the resources of a telecommunication network that uses a number of different switching technologies. The resource model comprises three layers, a network layer (13), a node layer (14) and a component layer (15), each layer comprising resource objects (10, 11, 12). The resource objects of the network layer are encapsulated to applications (PSTN, B-ISDN) which use the network. The resource objects of the node layer are encapsulated to the resource objects of the network layer and the resource objects at the component layer are encapsulated to the resource objects of the node layer. The resource model comprises connection handling function (18, 19, 20A-C) for setting up connections in the telecommunication network. The functions are divided into function components. Function components (18) at the network layer operate on resource objects at the network layer only, function components (19) at the node layer operate on resource objects at the node layer only and function components (20A-C) at the component layer operate on resource objects at the component layer.
