Patent number: 10313515Abstract: An apparatus and a method for determining a state of a counterpart without executing a separate program executed in order to determine a current state of the counterpart in a communication apparatus are provided. The apparatus includes a state information server and a communication apparatus. When receiving state information, the state information server provides the received state information to a user who has registered the communication apparatus that has provided the state information. When receiving state information from the state information server, the communication apparatus outputs the user's state information corresponding to the state information.Type: GrantFiled: October 1, 2009Date of Patent: June 4, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Si-Baek Kim, Eung-Moon Yeom

Patent number: 8804506Abstract: A voice/data combination system and a method that manages a bandwidth in the system. A determination is made as to whether a bandwidth for real-time data service is available, and the bandwidth, when not available, is reserved, so that the real-time data service is performed when the bandwidth is available. The system reserves predetermined bandwidths for real-time packets when bandwidth of real-time packets is not available, and process the real-time packets in their corresponding reserved bandwidth when bandwidth is available. Therefore, real-time packets and general packets are always processed in their corresponding bandwidths.Type: GrantFiled: January 18, 2008Date of Patent: August 12, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Eung-Moon Yeom

Patent number: 8391147Abstract: An IP converged system includes a VoIP ALG module and a policer module. The VoIP ALG module acquires dynamically changing RTP IP/port information of a packet by parsing a VoIP SIP message, and transmits the RTP IP/port information to the policer module. The policer module sets IP/port, which provides a real-time data service, by referring to the information from the VoIP ALG module, and discriminatively sets a packet processing condition for a non-real-time data service and a packet processing condition for the real-time data service. The VoIP ALG module and the policer module share RTP IP/port information, dynamically determined by the negotiation between VoIP gateways or VoIP terminals, in call setup/release, so that the policer can discriminately drop or mark VoIP packets by referring to the RTP IP/port information.Type: GrantFiled: June 12, 2008Date of Patent: March 5, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Eung-Moon Yeom

Patent number: 7519732Abstract: A routing service method in a public switched telephone network (PSTN) system uses a stand-alone gateway interworking with disparate central office lines. The stand-alone gateway checks whether a call service can be provided over the Internet with reference to an internal database having periodically updated call service state information in response to a call service request from a calling private branch exchange (PBX) connected to the stand-alone gateway via a central office line. If the call service cannot be provided over the Internet, the stand-alone gateway transmits a call service request, together with a public switched telephone network (PSTN) rerouting control request, to the calling PBX. The calling PBX transfers the call to a called party over the PSTN in response to the PSTN rerouting control request.Type: GrantFiled: April 30, 2002Date of Patent: April 14, 2009Assignee: Samsung Electronics Co., Ltd.Inventor: Eung-Moon Yeom

Patent number: 7415004Abstract: A method for establishing VoIP connection between a caller and a called party. Upon receipt of a first dial tone, the caller enters only the access code of the called party's central office. Then, VoIP call setup and a speech path are established between a remote gateway and the caller via a local gateway. A second dial tone is generated by the central office of the PSTN of the called party and this dial tone is relayed to the caller which prompts the caller to enter the telephone number of the called party to thereby establish communication between the caller and the called party.Type: GrantFiled: October 15, 2002Date of Patent: August 19, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Eung-Moon Yeom, Jung-Gi Kim

Patent number: 7289486Abstract: A method for call processing and link test in a Voice over Internet Protocol (VoIP) Gateway and system thereof. When a Gateway with Gatekeeper is operated in manual Registration/Admission/Status (RAS) mode, the link test is selectively performed depending on the status of the Gatekeeper according to an access code, whereby traffic of the Gatekeeper can be dispersed. In addition, when the Gateway with Gatekeeper is operated in manual RAS mode, depending on the status (i.e. enable or disable) of the Gatekeeper according to the access code, VoIP call processing or call routing service is divided into public VoIP service for charging a VoIP call and local VoIP service with free of charge. In case there is no routable Gateway during the VoIP call service, the call is detoured to Public Switched Telephone Network (PSTN) network for processing. As a result, service reliability of VoIP network is greatly improved.Type: GrantFiled: December 11, 2003Date of Patent: October 30, 2007Assignee: Samsung Electronics Co., Ltd.Inventor: Eung-Moon Yeom

Publication number: 20070192847Abstract: A dynamic network security system and control method thereof dynamically judges application of a firewall in a router where firewall and VoIP ALG functions are integrated. A VoIP ALG for seamless VoIP service dynamically shares information (e.g., IP, port) on a VoIP media packet with the firewall, and thus when the VoIP media packet ingress a firewall intranet, firewall application on the VoIP media packet is intelligently processed. Unlike conventional methods set to statically apply firewall rule to particular IP and port, the firewall rule can be applied to or relieved from particular IP and port in real-time, and thus firewall policy can be operated more securely.Type: ApplicationFiled: December 28, 2006Publication date: August 16, 2007Inventor: Eung-Moon Yeom
