ABSTRACT:
The present invention relates to a switching method and apparatus for performing a switching operation in a telecommunication network, wherein a side information and a service information generated based on a received call is converted into a switching technology independent identification information for identifying a start point and an end point of a connection to be switched in said switching apparatus. Thus, the physical resources of the switch are abstracted to a logical model which provides a clear interface for call control and signaling applications. Logical resources are controlled by resource managers, such that the physical resources are hidden by the switching technology independent identification information of the start point and end point of the connection. Thereby, problems with different switching technologies can be solved, and the complexity and maintenance of call control applications can be reduced, since they handle logical resources independent of the switching techniques.
