Patent number: 9794831Abstract: The present invention provides a method for shortening signaling delay of ISC session transfer procedure, a network element for controlling ISC session transfer, a network element for anchoring a media path in ISC session transfer and a communication system including at least two terminals and the above two network elements. In the present invention, the SCC AS decides if a media path needs to be anchored in a media anchor point MRF, and if yes, then instructs a MRF to assign respective media endpoints for a local UE and a remote UE and connect the two media endpoints together, so as to divide the session between the local UE and the remote UE into two independent sub-sessions: a session between the local UE and the MRF, and a session between the remote UE and the MRF. For these two sub-sessions, the SIP signaling is terminated and sent out in the SCC AS. Thus, when a local UE or a remote UE triggers handover, only one sub-session needs to be updated/influenced.Type: GrantFiled: October 30, 2009Date of Patent: October 17, 2017Assignee: Alcatel LucentInventors: Zhengxiong Lei, Xueqiang Yan, Zhiyuan Hu, Yonggen Wan

Patent number: 9787491Abstract: Systems and methods are disclosed for interleaving communications with a home area network (HAN) and a data network. A gateway device interleaves communications within timeslots of a time slotted channel hopping protocol. A gateway device can be configured to determine, during a first portion of a timeslot, whether the gateway device received a portion of a message from a data network. If the gateway device receives no messages from the data network during the first portion of the timeslot, the gateway device switches to listen for communication from the HAN during a second portion of the timeslot. If the gateway device receives a portion of the message from the HAN, the gateway device continues to receive receives the remainder of the message until one or more trigger conditions that cause the gateway device to listen for communication from the data network.Type: GrantFiled: August 19, 2015Date of Patent: October 10, 2017Assignee: Landis & Gyr Innovations, Inc.Inventors: Chris Calvert, Stephen Chasko, James Hartman, Sean Holcombe, Jeff Shudark

Patent number: 9787540Abstract: A method for predictive network congestion control may include receiving network traffic data of a network. The network traffic data may be indicative of a current level of use or the network. A predicted future level of use at the location of the network may be identified based on the received network traffic data and based on past network traffic data for the location of the network. A recommendation to alter the future level of use for the location may be generated. The recommendation may include a type of alert to transmit to devices of users in the location of the network. The recommendation may be transmitted to a network policy management server of the network.Type: GrantFiled: September 10, 2012Date of Patent: October 10, 2017Assignee: SAP SEInventors: Dennis Landscheidt, Marc-Oliver Klein

Patent number: 9775102Abstract: Methods and systems are described for determining an optimal access point for a client device based on the relative difference between signal strengths of wireless signals received by the client device from access points. In particular, the signal strengths of wireless signals received by a client device from access points are determined without receipt of signal strength and/or transmit power information from the client device. Instead, the signal strength difference value may be determined based on known characteristics of signals transmitted by the access points and known characteristics of signals received by the access points from the client device. This relative difference value may thereafter be used to determine an appropriate access point to provide network access to the client device.Type: GrantFiled: July 29, 2014Date of Patent: September 26, 2017Assignee: ARUBA NETWORKS, INC.Inventors: Jin Xie, Jiwoong Lee, Sachin Ganu

Patent number: 9774570Abstract: Methods and systems are provided for increasing application performance and accelerating data communications in a WAN environment. According to one embodiment, packets are received at a flow classification module operating at the Internet Protocol (IP) layer of a first wide area network (WAN) acceleration device via a private tunnel, which is operable to convey application layer data for connection-oriented applications between WAN acceleration devices. The packets are passed to a WAN socket operating at the transport layer. Based on the application protocol, the packets are passed to an application handler of multiple application handlers operating at the application layer each of which implements one or more application acceleration techniques for a particular application layer protocol known to behave poorly within a WAN environment. The existing connection-oriented flow is securely accelerated by performing one or more application acceleration techniques and applying one or more security functions.Type: GrantFiled: July 28, 2015Date of Patent: September 26, 2017Assignee: Fortinet, Inc.Inventors: Wenping Luo, Hongwei Li, Yixin Pan, Tao Huang

Patent number: 9756553Abstract: A method and system provide assisted acquisition of a wireless link between user equipment and a femtocell unit. After an initial calibration of timing and/or frequency information, the user equipment enters into a low-power state. The femtocell unit monitors for system updates using a network listen module that sniffs the air interface of one or more neighboring cells. Upon a trigger event, the femtocell unit provides aiding information, for example, timing and/or frequency information corresponding to a change in timing and/or frequency of the air interface, over a second radio, e.g., a wireless personal area network interface. Thus, the user equipment may remain in the low-power state and receive updates with respect to the wireless wide area network interface. Subsequently, upon wake-up, the user equipment may utilize the aiding information, for example, to recalibrate its timing and/or frequency. Thus, acquisition of the wireless link with the femtocell unit may be expedited.Type: GrantFiled: September 16, 2010Date of Patent: September 5, 2017Assignee: QUALCOMM IncorporatedInventors: Samir S.

Patent number: 9749236Abstract: Handling of ELS REQ and RSP packets that contain addresses in the payload is shifted to the edge fabric switches connected to the node devices issuing and receiving the ELS REQ packet, the ingress and egress switches. This allows the ELS REQ and RSP packet payload address modification operations to be removed from the tasks handled by the router processor. As this removes a processing burden from the router processors, those router processors are free to handle other normal operations, thus allowing more processor bandwidth to be provided to those other operations, which allows further growth of the network as one limitation has been removed. The need to replicate or provide commands between switches or routers is avoided as there are no redundant paths at that point.Type: GrantFiled: July 29, 2014Date of Patent: August 29, 2017Assignee: Brocade Communications Systems, Inc.Inventor: Badrinath Kollu

Patent number: 9749877Abstract: A method and apparatus are used for detecting a radio link (RL) failure and a post verification process. A quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then an occurrence of an RL failure is declared and a transmission over the E-DCH in a cell forward access channel (CELL_FACH) state is terminated. In a case of the post verification failure, E-DCH resources are released.Type: GrantFiled: December 28, 2012Date of Patent: August 29, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Christopher Cave, In H.
