Patent number: 11929781Abstract: An objective is to provide a terminal device, a communication method, and a communication system in which the time taken by connection operations/authentication operations does not increase proportionally with the pattern length, even if the transmitting side and the receiving side are not synchronized. A terminal device, a communication method, and a communication system according to the present invention create n pieces of signal information (n-bit patterns) by sequentially shifting each bit of a single piece of received signal information (n-bit pattern) one bit at a time. Through the above, signal information time-shifted by one bit each is obtained. Thus, even if the transmitting side and the receiving side are not synchronized, one of the n pieces of signal information is a signal synchronized with the transmitting side. Thereafter, the signal synchronized with the transmitting side can be detected by a brute-force calculation with the patterns (ID information) in the list.Type: GrantFiled: January 23, 2020Date of Patent: March 12, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Ryota Shiina, Tomohiro Taniguchi, Kazutaka Hara, Shinya Tamaki, Tomoki Murakami, Toshiro Nakahira

Patent number: 8509221Abstract: An optimized gateway selection process of the present invention is based on a universal mobility manager (UMM), a component for inter-technology location management. The UMM is capable of holding location information for diverse cellular networks, as well as for Internet telephony systems. For cellular networks, UMM acts as a traditional HLR; for an Internet telephony network, it acts as the entities that are responsible for user/terminal registration (registrar in SIP, gatekeeper in H.323) and address resolution (proxy server in SIP, gatekeeper in H.323). An optimal gateway selection is possible based on location related information provided by the UMM which had not previously been available. Utilizing the newly available information enables a gateway to be selected which may, for example, enable the circuit switched portion of a call to now be minimized.Type: GrantFiled: December 15, 2009Date of Patent: August 13, 2013Assignee: Alcatel LucentInventors: Parag M.

Patent number: 7822416Abstract: Techniques are provided to allow global roaming between different devices in different networks, using different protocols. A system may contain one or more protocol dependent logic servers (PDLSs), in which each PDLS is associated with a particular network/network protocol. The networks may comprise one or more wired telecommunications networks, wireless communications networks, or Internet-based networks. When a first PDLS receives an incoming, protocol-dependent message comprising a first protocol from a first network intended for a user currently registered on another network, the first PDLS converts the protocol-dependent message into an incoming, protocol-independent message and forwards it to another network element, such as a core logic server (CLS). The CLS processes the incoming, protocol-independent message, generates an appropriate outgoing protocol-independent message and forwards this message to a second PDLS.Type: GrantFiled: May 12, 2003Date of Patent: October 26, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Triantafyllos Alexiou, Kuo-Wei Chen, Ramana Isukapalli, Thomas La Porta, Kazutaka Murakami, Ming Xiong

Patent number: 7756122Abstract: A Global Roaming Application Server is adapted to act as an intermediary between all Internet Protocol (IP)-based network(s) and non-IP-based network(s), such as a circuit-switched landline network, an ANSI-41 network, wireless LAN network, a Global System for Mobile Communications network or Universal Mobile Telecommunications System network. In a first or forward direction, the Application Server enables a user in a non-IP network to be located in accordance with user profiles at the request of another user who has chosen to send a message via an all-IP based network. After the user in the non-IP network is so located, the Application Server enables a signaling link to be created between the two users. The Application Server may also be used to enable a signaling link when a message is sent in a second, or reverse direction.Type: GrantFiled: May 12, 2003Date of Patent: July 13, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Triantafyllos Alexiou, Parag M.

Patent number: 7239618Abstract: Local mobility within a subnet is supported by classifying wireless base stations, and the routers used to forward packets to those base stations, within defined domains. Domains are defined to incorporate a subnet having a plurality of base stations. Base stations are used by mobile devices to attach to the wired portion of a packet-based network, such as the Internet, and exchange packets thereover with a correspondent node. Packets sent from the correspondent node to the mobile device have a packet destination address corresponding to the mobile device. The mobile device retains this address for the duration of time it is powered up and attached to the Internet via any base station within a given domain. Host-based routing is utilized to update routing table entries corresponding to the mobile device at routers incorporated within a single domain.Type: GrantFiled: December 11, 1998Date of Patent: July 3, 2007Assignee: Lucent Technologies Inc.Inventors: Thomas F.
