| 摘要 |
The invention relates to a network arrangement and a method respectively for call processing in a communications system and to a communications system comprising such network arrangement. The network arrangement in which a call, which here may relate to e.g. speech, data, video transmission, etc., is to be set up between an originating point and at least one terminating point which are virtually represented by circuits, comprises a number of switches which are virtually represented by path objects and the communication path comprises a call part and a connection part. The connection part comprises a number of connection objects (2a) each comprising a number of path objects particularly virtually representing switches (6a) which are arranged in an object oriented hierarchical structure. At least a number of the path objects each comprise a base path object (3a) and a subpath object (4a) which are hierarchically arranged in a super class and a subclass, respectively. A base path object can be used by a connection object independently of the corresponding subpath object. The behaviour of the subpath object is given by the particular routing case.
