  • Patent number: 9742851
    Abstract: A method and arrangement for remotely controlling the communication of media between devices in different local networks (200, 202) using a remote control device (200b). The remote control device obtains discovery information on a first device (200c) and sends a remote access request over a multimedia service network to a home multimedia gateway (202b) in the opposite local network (202) for a connection to a second device (202c) therein. The home multimedia gateway then responds with communication parameters established for the second device in a residential gateway, and the remote control device can then order the first device to execute a multimedia session with the second device by using said communication parameters. This solution enables a remote control device visiting a local network to order a device in that network to fetch media content from a device in another home network, or vice versa.

  • Patent number: 9742707
    Abstract: Methods and systems for managing multiple transmit queues of a networking device of a host machine in a virtual machine system. The networking device includes multiple transmit queues that are used by multiple guests of the virtual machine system for the transmission of packets in a data communication. A hypervisor of the virtual machine system manages the switching from one or more transmit queues (i.e., old transmit queues) to one or more other queues (i.e., new transmit queues) by managing a flow of packets in the virtual machine system to maintain a proper sequence of packets and avoid a need to re-order the transmitted packets at a destination.

  • Patent number: 9730097
    Abstract: An effective SCELL activation procedure is proposed to reduce the SCELL activation time. For carrier aggregation, a secondary cell (SCELL) needs to be configured and then activated before a UE can perform normal operation. In a first embodiment, the UE performs measurements on a list of candidate SCELLs before SCELL configuration. In a second embodiment, the UE performs measurements on a configured SCELL with high priority after the SCELL is configured. In a third embodiment, the UE performs deactivated-state SCELL measurements with adaptive SCELL measurement interval based on a configured measurement cycle and a state machine. Small SCELL activation time allows energy saving and network scheduling gain.

  • Patent number: 9706555
    Abstract: During the operation of a radio access network (RAN), the RAN will determine a measure of capacity of a frequency channel based on a modulation quality (Rho) of the frequency channel and will intelligently manage use of the frequency channel based on the determined Rho. Through this process, the RAN may thereby attempt to serve each WCD with an appropriate level of service by reducing a maximum load level for the frequency channel. In response to a WCD attempting to register on a frequency channel, the RAN may determine if registering the WCD would cause a current load level to exceed the maximum load level of the frequency channel. If registering would cause a current load level of the frequency channel to exceed the maximum load level, the RAN may cause the WCD to register on a different frequency channel. If not, the RAN may allow the registration.
