Patent number: 7706292Abstract: A test packet generator of an entry device generates a delay test packet including priority information. A test packet transmitter of the entry device transmits the delay test packet to an exit device through a route corresponding to the priority information. A test packet receiver of the exit device receives the delay test packet. A reply packet transmitter of the exit device returns a reply-delay test packet toward the entry device through the same route in the counter direction. A reply packet receiver of the entry device receives the reply-delay test packet. A delay calculator of the entry device calculates a delay time on the basis of the time of transmitting the delay test packet and the time of receiving the reply-delay test packet. A route changer of the entry device changes routing appropriately on the basis of the delay time.Type: GrantFiled: November 19, 2007Date of Patent: April 27, 2010Assignee: Fujitsu LimitedInventors: Masayoshi Nakano, Kazuhiro Nakashima

Patent number: 7688850Abstract: A method is disclosed that enables a user to set their “away” or auto-reply messages for two or more communications services (e.g., e-mail, voice mail, etc.) in one action. Separate actions are required in the prior art to change each outgoing message for every distinct communication service. The illustrative embodiment of the present invention is a method that enables a user to change the auto-reply message for multiple communication services with less effort than was required for multiple services in the prior art. In accordance with the illustrative embodiment, a text auto-reply message intended for e-mail is automatically converted into an abbreviated form for instant messaging and wireless text services and into audio for services like telephony. Furthermore, the illustrative embodiment enables the automatic translation of messages into different natural languages, and can apply rules so that the resulting messages are used appropriately.Type: GrantFiled: November 14, 2006Date of Patent: March 30, 2010Assignee: Avaya Inc.Inventors: Ronald Lee Fletcher, Srinivasa R.

Patent number: 7675917Abstract: Discloses is a method for providing a packet data service in a wireless communication system. A packet data service node (PDSN) or a home agent (HA) allocates an IP (Internet Protocol) address to a mobile station and then registers the allocated IP address information in a DNS (Domain Naming System) server along with a domain name of the mobile station. Alternatively, upon receiving an accounting request message from the packet data service node, an AAA (Authentication, Authorization and Accounting) server registers the IP address information of the mobile station in the DNS server in association with the domain name of the mobile station. Thus, a correspondent node (CN), though it does not recognize the IP address of the mobile station, can access the mobile station using the domain name.Type: GrantFiled: September 11, 2002Date of Patent: March 9, 2010Assignee: Samsung Electronics Co., LtdInventors: Mi-Suk Ju, Dae-Joong Kim

Patent number: 7664130Abstract: The present invention eliminates a transmission-waiting operation which is unnecessary while accommodating a prioritized traffic. Although a communication station enters a transmission-disallowed state in response to detection of a signal addressed to another station in accordance with medium access control based on CSMA, if the communication station receives a frame transmitted with priority to a local station during the transmission waiting, it cancels the transmission-disallowed state, sends back a frame responding the frame transmitted with priority and effectively operates a transmission prioritized period. The communication station starts a search procedure to perform a processing of evading duplication of the transmission prioritized periods if it judges a possibility of a problem occurring in a time zone in which reception with priority is possible.Type: GrantFiled: February 28, 2005Date of Patent: February 16, 2010Assignee: Sony CorporationInventors: Kazuyuki Sakoda, Kenzo Nishikawa, Yuichi Morioka, Mitsuhiro Suzuki

Patent number: 7620065Abstract: A method and application for selecting a network from one or more candidate networks is disclosed. Information is gathered from one or more database relating to each of the one or more candidate networks and is harmonized in relation to an associated network type. The harmonized information is evaluated to allocate a weight to each of the candidate networks. The weight represents the desirability of each of the candidate networks. The required resources to connect to each of the candidate networks are determined from information contained within the service-provider database, from information obtained by the end-user, and by self-adaptive learning algorithms. At least one of the candidate networks is selected based on the allocated weight of the candidate network and the application attempts to connect to the candidate network. The method and application incorporates the ability to control and integrate a plurality of services on a user device via the candidate network.Type: GrantFiled: July 22, 2005Date of Patent: November 17, 2009Assignee: Trellia Networks, Inc.Inventor: Eric Falardeau
