  • Call control system and method for automatic routing of circuit switched data connections based upon stored communication link information
    Patent number: 7493411
    Abstract: A method and apparatus for automatic routing of multi-link circuit switched connections are shown. A routing processor monitors the behavioral characteristics of a previous connection from an originating client and stores data relating to the characteristics of the previous connection. In particular, data is stored regarding the previous connection which is not available until after call completion of the previous connection. When the originating client initiates a subsequent connection, the routing processor retrieves the data relating to the behavioral characteristics of the previous connection and efficiently routes the subsequent based upon the behavioral characteristics.
    Type: Grant

  • Method and apparatus for automatic routing of circuit switched data connections based upon stored behavioral information
    Patent number: 6529959
    Abstract: A method and apparatus for automatic routing of multi-link circuit switched connections are shown. A routing processor monitors the behavioral characteristics of a previous connection from an originating client and stores data relating to the characteristics of the previous connection. In particular, data is stored regarding the previous connection which is not available until after call completion of the previous connection. When the originating client initiates a subsequent connection, the routing processor retrieves the data relating to the behavioral characteristics of the previous connection and routes the subsequent connection along a route which is advantageous to serving the behavioral characteristics of the subsequent connection.
