Patent number: 8451827Abstract: A circuit and method are presented for signal processing and routing of digital voice telephony signals, using a specialized high-density integrated circuit voice processor. The voice processor performs several essential functions required for telephony processing, including echo cancellation, protocol conversion, and dynamic range compression/expansion. These functions are traditionally performed by multiple circuits or modules. By combining these capabilities in a single device, power and circuit board area requirements are reduced. The embodiment of the circuit and method disclosed herein include novel implementations of a time-slot interchange circuit and a telephony signaling circuit. Both of these circuits are designed to minimize demands on the signal processing engines incorporated within the voice processor, and account for very little of the on-chip circuitry.Type: GrantFiled: October 30, 2009Date of Patent: May 28, 2013Assignee: LSI CorporationInventor: Danny C.

Patent number: 8363663Abstract: A method is described for routing data from a first node to a second node via a gateway. The second node is detected at the gateway, which determines a local identifier of the second node. A name and a global address are associated with the second node. The name and the global address are published to a name service, such that the first node can retrieve the global address based on the name. The gateway receives data from the first node that is addressed to the global address and transmits the data to the second node using the local identifier. The gateway includes software implementing a service-oriented architecture (SOA). Any number of additional services may be added to process messages passing through the gateway.Type: GrantFiled: April 2, 2009Date of Patent: January 29, 2013Assignee: The Boeing CompanyInventors: Brian James Smith, Marcelo M.

Patent number: 8358646Abstract: The present invention makes it possible to connect to and communicate with a connect destination by using a temporary number. In the present invention, a temporary number user terminal (100) registers a temporary number acquired from a SIP account server (300) in a SIP proxy server (400), and connects to and communicates with a connected user terminal (200) by using the temporary number. After the communication is finished, the temporary number is unregistered from the SIP proxy server (400), thereby disabling a connection from the connected user terminal (200). Also, connection conditions are provided by specifying the validity period of connection using a temporary number, the number of times connection can be made, the connect destination to which connection can be made, and the like, and only those calls which meet the connection conditions are accepted, thereby making it possible to restrict the uses of the temporary number.Type: GrantFiled: July 24, 2008Date of Patent: January 22, 2013Assignee: Sony CorporationInventors: Masato Kawada, Yoshiya Asaumi, Yasuto Masuda
