  • Patent number: 9912693
    Abstract: A server system generates and transfers Precision Time Protocol (PTP) synch requests for delivery to a PTP clock server and responsively receives PTP synch responses transferred by the PTP clock server. The server system processes the PTP synch responses to determine PTP clock phase error data for the PTP clock server. The server system compares the PTP clock phase error data to a historical phase error threshold for the PTP clock server. If the PTP clock phase error data does not exceed the historical phase error threshold, then the server system updates the historical phase error threshold for the PTP clock server based on the PTP clock phase error data. If the PTP clock phase error data exceeds the historical phase error threshold, then the server system generates an indication that the PTP clock server comprises a malicious PTP node.

  • Patent number: 9882742
    Abstract: A data communication network controls the amounts of virtual network elements it uses. A control system processes user data packets from multiple wireless base stations to determine amounts of user data packet tunnels for a plurality of Quality-of-Service (QoS) levels. The control system processes the amounts of the user data packet tunnels for the QoS levels to identify a target amount of virtual packet gateways to serve the user data packet tunnels. A virtual network element system implements the target amount of the virtual packet gateways to serve the user data packet tunnels at the QoS levels with the virtual packet gateways.

  • Patent number: 9565645
    Abstract: Methods for wirelessly connecting a small cell to a grandmaster timing device are disclosed. The methods can include identifying one or more grandmaster timing devices and wirelessly requesting an IP address to enable a small cell to connect to a grandmaster timing device for time synchronization. The methods may further include selecting a grandmaster timing device based on a predetermined preference order that includes a relative preference level for different types of grandmaster timing devices.

  • Patent number: 9473385
    Abstract: An LTE network, having a plurality of base stations and S-GWs, processes GTP packets to determine an amount of GTP tunnels between the base stations and the S-GWs gateways. The LTE network processes the amount of GTP tunnels to determine a target amount of LTE P-GWs to serve the base stations. If the target amount of the LTE P-GWs is greater than a current amount of the LTE P-GWs, then an additional amount of virtual LTE P-GWs is implemented to serve the base stations. If the target amount of the LTE P-GWs is less than the current amount of the LTE P-GWs, then an extra amount of the virtual LTE P-GWs that serve the base stations are removed.

  • Patent number: 8265042
    Abstract: A communication system for providing an accurate timing signal and synchronization information is described herein. The communication system comprises a Precision Time Protocol (PTP) server, a Global Positioning System (GPS), a pseudowire device, and a PTP client. The PTP client receives a time of day data and frequency information from the PTP server, receives a timing signal from the GPS, synchronizes the time of day data and timing signal to create synchronized a time of day signal, and provides the synchronized time of day signal to the pseudowire device. The pseudowire device processes the synchronized time of day signal and the frequency information to perform a time-division multiplexing signal to Ethernet signal synchronized conversion.
