Patent number: 7260101Abstract: Configuration of a new point code connected to a SS7 network through a MTP level 3 aligned link, involves listening to point code status massages originating from distant point codes and forwarded on said link. When a message originating from an unknown distant point code is received, the table of distant point codes is updated with the point code number of the distant point code; at the same time, a primary route to the new distant point code through the link may be created. Therefore, configuration and testing of a new point code within an existing SS7 network, without having to re-enter the full network architecture, is facilitated.Type: GrantFiled: January 8, 2001Date of Patent: August 21, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: Pierre Sauvage, Eric Julien

Patent number: 7184542Abstract: The present invention relates to the field of tone detection and, more particularly, to the detection of dual tone multi-frequency (DTMF) tones in software based telecommunications systems. As modem telecommunications systems are becoming increasingly software based and typically require only a minimum of physical hardware, much of the necessary telecommunication functionality is now provided by software functions running on powerful computer servers. A common function which is required to be performed by telecommunications systems is that of dual tone multi-frequency (DTMF) detection. Accordingly, the present invention aims to provide an efficient software-based DTMF detection system that satisfies the ever increasing need for efficient software functions.Type: GrantFiled: February 7, 2003Date of Patent: February 27, 2007Assignee: Hewlett-Packard Development, L.P.Inventors: Pierre Sauvage, Simon Morlat

Patent number: 7150023Abstract: The invention suggests providing in a processing system a licence controller (1), for controlling use of a resource by processes (3, 5, 7); for each process to be controlled, there is provided an inter-process communication (9, 11) between the process and the licence controller. A process and the licence controller exchange through the inter-process communication of the process information regarding actual and allowed use of the resource by the process. According to this information, the process may be controlled, be it on a self-control basis or through control of the licence controller. Use of the resource to be dynamically adapted; high availability is guaranteed since processes may operate even when the licence controller fails.Type: GrantFiled: July 27, 2001Date of Patent: December 12, 2006Assignee: Hewlett-Packard Development Company L.P.Inventor: Pierre Sauvage

Patent number: 6651185Abstract: A high availability platform runs a fault-tolerant controller process (FTC) and at least one monitored process that indicates its live state by periodically sending a heart-beat message to the FTC. The FTC responds to the heart-beat message by modifying the frequency at which it expects the heart-beat message according to information contained therein. The platform may run an additional process, the monitored process being adapted to regularly send the additional process a message and to notify the FTC that the additional process is dead when it receives an error code from an operating system after sending a message to the additional process.Type: GrantFiled: April 24, 2000Date of Patent: November 18, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventor: Pierre Sauvage

Publication number: 20030076938Abstract: A process and apparratus for controlling the generation of statistical information being reported to a user or administration application (43) by a Common Channel Signalling (CCS) protocol stack (41) of a telecommunication node (40). The process involves the use of a Statistics Control File (SCF) file (42) which is located within the protocol stack and which contains a description of the entities, including links and destinations, for which a statistical notification is to be reported to the administration application (43). By modifying the contents of said SCF file contained within the protocol stack via the administration application, the user is given the possibility to precisely define the particular statistical information for which he finds an interest. There is reduced the number of unnecessary statistical information reported back by the protocol stack. The Statistics Control File (SCF) 42 contains a description of the entities complying with the Specification and Description Language (SDL) standard.Type: ApplicationFiled: September 19, 2002Publication date: April 24, 2003Inventor: Pierre Sauvage

Patent number: 6163881Abstract: A method is provided for automatically storing indications regarding conditions prevailing in a computer running a user application (1) that employs a library (2). This method involves providing an interface component (3) interposed between the user application and library. The interface component (3) is arranged to receive messages from the user application (1) destined for the library (2), pass on these messages to the library (2), and monitor and store indications regarding conditions prevailing in the computer at the time the messages are received or passed. Provision is made for dynamically changing the indications to be monitored.Type: GrantFiled: March 20, 1997Date of Patent: December 19, 2000Assignee: Hewlett-Packard CompanyInventor: Pierre Sauvage

Patent number: 5978933Abstract: A fault tolerant platform is provided that comprises two systems running pairs of processes in the active and standby state, one process from each pair running on each system. Each system comprises a fault-tolerance controlling process, first communication channels provided between the fault-tolerance controlling process and the processes in the active or standby state running on its system, and second communication channels provided between the fault-tolerance controlling processes. Management of fault tolerance (that is, promoting a process in a standby state to the active state, and making a process in an active state exit from the active state) is handled by the fault-tolerance controlling processes. A generic management of fault tolerant processes is thus provided in which fault detection and switchover is carried out independently of the applications. The invention thus ensures efficient and coherent switchover between active and standby processes.Type: GrantFiled: January 11, 1996Date of Patent: November 2, 1999Assignee: Hewlett-Packard CompanyInventors: Brian Christopher Wyld, Jean-Michel Rosset, Pierre Sauvage, Denis Pierrot, Pierre D.

Patent number: 5436856Abstract: The present invention relates to a testing method for an intermediate circuit between a microprocessor and surrounding circuits comprising a first set of access routes including lines of a data bus (D) and a control bus (C), and a second set of access paths comprising lines (AH) connected to other lines (CS) through a processing circuit (40). This method consists in providing in the intermediate circuit a test register (46) addressable by addresses ignored by the other elements of the circuit; writing test words in the test register through either one of the first and second set of as paths; reading the written words in the test register through the other set of access paths; and checking whether the read words correspond in a predetermined way to the test words.Type: GrantFiled: November 15, 1993Date of Patent: July 25, 1995Assignee: Hewlett-Packard CompanyInventor: Pierre Sauvage
