  • Patent number: 7403992
    Abstract: A method and system for improving the session establishment or modification performance of a switching system. Statistics associated with the use of session resources within the switching system are collected. Based on these statistics a given session resource is recorded to a connection cache to become reusable for subsequent sessions. In subsequent session establishment or modification within the switching system the connection cache is checked whether there is any matching session resources. If a matching session resource is found, it is used in the establishment of the communication paths pertaining to the session to be established or modified.

  • Patent number: 7233596
    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 the 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.
