Publication number: 20150134793Abstract: A common IP layer client device interface within an IP multimedia gateway (IMG) is configured to connect client devices to broadband IP networks such as the Internet based on determined device capabilities. Broadband IP network interfaces within the IMG are configured to enable communication between the IMG and broadband IP networks based on the determined device capabilities. Content provided by various service managers are communicated with the client devices utilizing the common IP layer client device interface and the configured network interfaces. Network capabilities may be determined during the device and network discovery. Protocol translation, media transcoding and/or dynamic device configuration may be performed based on the determined device capabilities, and based on the determined network capabilities. The IMG may adjust system timing and manage power consumptions for service deployment over corresponding client devices.Type: ApplicationFiled: January 23, 2015Publication date: May 14, 2015Inventors: Gordon Li, Xuemin Chen, John McQueen, Sam Anderson, Pierre Couillaud, Richard Schwartz

Patent number: 8800022Abstract: An IP multimedia gateway (IMG) may be operable to identify a client device which may not currently possess a security capability that is compatible with a security capability of a service manager for receiving a service from the service manager. A security process between the client device and the service manager may be enabled by the IMG to enable the client device to receive the service from the service manager. The client device may be local to the IMG or remote with respect to the IMG. The IMG may enable an authentication process between the client device and the service manager by performing authentication translation. The IMG may enable a cryptography process between the client device and the service manager by performing cryptography translation. The IMG may enable an authorization process for authorizing the client device to access a particular content by performing access control conversion.Type: GrantFiled: July 1, 2010Date of Patent: August 5, 2014Assignee: Broadcom CorporationInventors: Xuemin Chen, Gordon Yong Li, Sam Anderson, Pierre Couillaud

Patent number: 7533174Abstract: In a packet-based telephony network, a media gateway provides information on active media path connections to an active call server. For instance, this data may be provided to a backup call server to keep the backup call server in a warm standby mode. The backup call server polls a media gateway to retrieve a table of information on active media path connections. The polling may be done periodically or only during switchover from the active call server to the backup call server. After switchover, the backup call server has all necessary details about active media path connections to provide accurate billing information. Alternatively, after a temporary failure at the active call server, the active call server may send a request to the media gateway to retrieve a table of information on active media path connections.Type: GrantFiled: September 29, 2000Date of Patent: May 12, 2009Assignee: Nortel Networks LimitedInventors: John C. Lynch, Pierre Couillaud, Metodej E. Valentik

Patent number: 6839344Abstract: A method and apparatus are provided for establishing and maintaining a backhaul link over an Internet Protocol based network for transporting Layer 3 ISDN messages. A signalling gateway establishes a TCP connection to a Media Gateway Controller through the IP based network. The Layer 3 ISDN messages generated within an ISDN network attached to the IP based network are then transported between the signalling gateway and the Media Gateway Controller over the TCP connection. The integrity of the TCP connection is monitored using a heartbeat mechanism based on UDP packets. Both the signalling gateway and the Media Gateway Controller transmit UDP packets at regular intervals, and monitor for the arrival of UDP packets from the other device. If a provisioned number of consecutive UDP packets do not arrive from the other device, then a failure of the backhaul link is declared. The signalling gateway then attempts to re-establish the backhaul link.Type: GrantFiled: December 19, 2000Date of Patent: January 4, 2005Assignee: Nortel Networks LimitedInventors: Pierre Couillaud, Milos D. Pujic, Craig S. Telke
