  • Patent number: 9564911
    Abstract: Methods and apparatuses featuring a multiplying injection-locked oscillator are described. Some embodiments include a pulse-generator-and-injector and one or more injection-locked oscillators. The outputs of the pulse-generator-and-injector can be injected into corresponding injection points of an injection-locked oscillator. In embodiments that include multiple injection-locked oscillators, the outputs of each injection-locked oscillator can be injected into the corresponding injection points of the next injection-locked oscillator. Some embodiments reduce deterministic jitter by dynamically modifying the loop length of an injection-locked oscillator, and/or by using a duty cycle corrector, and/or by multiplexing/blending the outputs from multiple delay elements of an injection-locked oscillator.

  • Publication number: 20160262083
    Abstract: A method for mobility management for a mobile node that establishes a connection with a first network while in a second network and traverses to a third network includes transferring location management information from the second network to the first network. An indirection path from the first network to the third network is established for data packets directed to the mobile node. The data packets directed to the mobile node are transferred using the indirection path without traversing the second network. This allows for the address anchor of the connection to remain at the second network while providing a flow anchor at the first network, which allows a direct flow to the third network.

  • Patent number: 9307470
    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.

  • Patent number: 9271197
    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.
