Latest Patents

Driscoll's latest patents include innovative methods and arrangements for associating control messages received in the D-channel of an ISDN line with the call control process. His first patent describes how a single control channel can be used concurrently to manage multiple calls. It details the creation of a call control process and data structure that includes the unique identity of each call. When a control message is received, the associated data structures are searched until a match is found, allowing for efficient call management. If no match is found, a new process and data structure are created to handle the call setup.

The second patent focuses on properly associating alerting messages from ISDN user terminals with their respective control processes. It outlines a method where each call is linked to a call control process and data structure. Upon receiving an external call request, a data structure is created, and a message is sent to the user terminal. The terminal responds with an alerting message, which is then used to uniquely identify the terminal engaged in the call.
