Patent number: 9178718Abstract: The present invention provides a method for dealing with a PS domain service and realizing a PS domain service request for a mobile terminal and the mobile terminal. The method comprises: identifying, by the mobile terminal, a type of a PS domain signaling process that is used for realizing a PS domain service; when the type of the PS domain signaling process belongs to a first type, acquiring a result of the PS domain signaling process corresponding to the PS domain signaling process; and when it is judged that the result is network refusal and the reason for refusal is Reason #7 (GPRS service not allowed), judging that a Public Land Mobile Network (PLMN) on which the mobile terminal currently resides is not a Home Public Land Mobile Network (HPLMN) and adding the PLMN into a list of forbidden PLMNs for GPRS service. According to the above technical solution, it is able to provide a GPRS service on a HPLMN or other PLMNs, thereby to provide a user with a PS domain service with the biggest possibility.Type: GrantFiled: December 2, 2011Date of Patent: November 3, 2015Assignee: ST-ERICSSON SEMICONDUCTOR (BEIJING) CO., LTDInventor: Huan Pu

Patent number: 9172599Abstract: Systems and methods are described to provide fault tolerant folded Clos networks. A folded Clos network is disclosed including a set of tier 1 routers interconnected with a set of tier 2 routers. Tier 1 routers are configured to view a set of tier 2 routers as a single aggregate router. Accordingly, tier 1 routers are unaware of faults between tier 2 routers and additional tier 1 routers. A throwback router is connected to each tier 2 router to facilitate handling of data under such fault conditions. When a tier 2 router receives undeliverable data, the data is passed to a throwback router, which retransmits the data to an additional tier 2 router. Data that is retransmitted multiple times can be disregarded by the throwback router.Type: GrantFiled: December 17, 2013Date of Patent: October 27, 2015Assignee: Amazon Technologies, Inc.Inventors: Thomas Bradley Scholl, Andrew Bruce Dickinson

Patent number: 9166675Abstract: Aspects of the invention provide a system and method to allow inroute frame timing synchronization without the aid of hub signal loopback or satellite ephemeris data. Furthermore, it allows tracking and compensating of the satellite motion to allow multiple remotes to use TDMA on the inroute frequencies, while minimizing the aperture. Two main techniques proposed are CLT and polling based approaches, which are used in combination for an optimum solution. In CLT based approach, hub transmits remote specific timing correction feedback messages on the outroute on as needed basis. In polling based approach, the remotes derive their timing based on a per-beam average delay estimate broadcast by the hub and a measured local delay specific to each outroute stream from a remote. An aspect of the invention uses triangulation method to determine satellite position. Furthermore, an aspect of the invention uses hub burst arrival method instead of polling approach.Type: GrantFiled: April 29, 2014Date of Patent: October 20, 2015Assignee: Hughes Network Systems, LLCInventors: Udaya Bhaskar, Yezdi Antia, Satyajit Roy

Patent number: 9166930Abstract: Technologies generally described herein relate to waved time multiplexing. In some examples, a command flit can be transmitted from a sender node of a network-on-chip (“NOC”) to a destination node of the NOC via an intermediate node along a circuit-switched path. The command flit can include an interval period and a release duration. When the command flit has been transmitted, one or more data flits can be transmitted from the sender node to the destination node via the intermediate node along the circuit-switched path. The sender node, the destination node, and the intermediate node can be configured to reserve router resources of the sender node, the destination node, and the intermediate node respectively for circuit-switched traffic during a use duration of the interval period and to release the router resources for packet-switched traffic during the release duration in a waved time multiplex arrangement.Type: GrantFiled: October 30, 2012Date of Patent: October 20, 2015Assignee: Empire Technology Development LLCInventor: Yan Solihin
