  • Publication number: 20140348130
    Abstract: An embodiment method for session handling for a connection between an UE and a network includes establishing, at a first distributed EPC, user and IP sessions over the connection through the first distributed EPC. The first distributed EPC includes a first PGW at which the IP session is anchored. The method also includes holding original IP resources and releasing original connection resources for the sessions at the first distributed EPC when the UE moves beyond the first distributed EPC to a second distributed EPC. The method then establishes a tunnel between the first PGW and a second PGW for the second distributed EPC. The tunnel utilizes the original IP resources and new connection resources at the second distributed EPC. The method then routes data from the tunnel, through the first PGW, and to the network.

  • Patent number: 8878998
    Abstract: A video decoder block provides a common pathway for processing video signals encoded using different video formats. The video decoder block passes the video signals through the same processing components in order convert the signals to a common format for display or storage. Each processing component cat be disabled or by-passed to enable or disable the function performed by the component. This reduces the number of components and signal processors required in devices that need to accommodate signals of different formats.

  • Patent number: 8873507
    Abstract: A method and system for optimizing mobility routing are disclosed. A preferred embodiment comprises a home local mobility anchor and two or more distributed local mobility anchors, wherein the distributed local mobility anchors have a reduced functionality from the home local mobility anchor. A first distributed local mobility anchor may send an initial data packet from a correspondent node to the home local mobility anchor, which may route the initial data packet to a second distributed local mobility anchor where a mobile node is anchored while also sending the location of the mobile node back to the first distributed local mobility anchor. Subsequent packets can be sent by the first distributed local mobility anchor directly to the second distributed local mobility anchor and bypassing the home local mobility anchor.

  • Patent number: 8824353
    Abstract: A method, system and device for achieving an optimized mobility routing path are disclosed. A preferred embodiment comprises a method of cutting unnecessary network tunnels. In a mobile network system, transmitting data packets through a tunnel is an effective way to provide network location privacy. An optimization method is proposed to consolidate two tunnels connecting with a network element such as a first distributed local mobility anchor (D-LMA). The first D-LMA informs a data packet sender such as a second D-LMA of the destination address saved in the first D-LMA. The second D-LMA updates its destination address accordingly and sends subsequent data packets to the destination directly. By applying this optimization method, a network system provides a further optimized route for data packets as well as location privacy.

  • Patent number: 8787776
    Abstract: An optical receiver includes a photodetector for detecting incoming optical data signals and an amplifier for providing signal gain and current to voltage conversion. The detection signal generated by the photodetector may include a distortion component caused by an operating characteristic of the photodetector. A signal compensating circuit may reconstruct the received optical data signal by effectively canceling the distortion component. For this purpose, the signal compensating circuit may include a decision feedback equalizer implemented using at least one feedback filter matched to the operating characteristic of the photodetector causing the signal distortion so as to reproduce the distortion component for cancellation. Use of a control module may also configure the optical receiver in real time to account for other operating and environmental conditions of the optical receiver.

  • Publication number: 20140016613
    Abstract: Single radio handovers (SRHOs) between heterogonous networks can be facilitated using several techniques. One such technique includes activating a receiver of a target radio interface in a mobile node without activating a transmitter of the target radio interface, thereby allowing the mobile node to perform target network discovery while the transmitter of the target radio interface remains deactivated. Another such technique includes encapsulating link-layer discovery frames into media independent handover frames (MIH), and then tunneling the MIH frames over a tunnel extending through the source network. This may allow the MN to achieve various handover related tasks without activating the target radio link. Another technique includes establishing a schedule (or delay period) for synchronizing deactivation of the source radio interface with activation of the transmitter in the target radio interface.
