  • Patent number: 10455508
    Abstract: A method and device for monitoring paging signals are provided. A method of DRX cycle extension for a mobile terminal in an IDLE mode is provided. The method is used to extend the current DRX cycle. A longer paging cycle is designed by extending a UE-specific paging cycle or introducing a new coefficient in system information. A method for extending the SFN is proposed in the invention. A boundary and a serial number of the SFN in the longer wrap around are indicated by the SI. To avoid a situation in which the high paging load occurs in certain paging frames or subframes, the UE_ID is extended in the invention. The proposed mechanism can flexibly adjust the paging cycle and the SFN extension to meet the actual requirements. The long DRX cycle can save a lot of power consumption of the mobile terminals in the IDLE mode.

  • Patent number: 10178032
    Abstract: Embodiments for a method of providing dynamic load balancing and fail-over in a WAN network. The interface group architecture for WAN is applied to both sides of the source-destination connection to redirect the data movement of read/write operations away from a public network to a private network. The process identifies interface group selection criteria to be invoked on both source and destination servers to select a tenant-specific private network interface for multi-tenant servers. The method provides high availability communication to select the interface for reads/writes as well as load balancing across the interfaces of each interface group, and a failover interface for recovery from interfaces of the interface group.

  • Patent number: 10148411
    Abstract: The present disclosure provides a secure one-step IEEE 1588 clock using either a symmetric or asymmetric protection scheme. Clocks of mission-critical or highly-available devices in industrial automation systems connected to a communication network are synchronized by sending, by a master clock, a synchronization message, e.g., a single message of the one-step-clock type according to IEEE 1588, including a time stamp, and by receiving and evaluating, by a slave clock, the synchronization message. A synchronization component or module of the master clock prepares, or composes, prior to a projected send time, a synchronization message including a time stamp of the projected send time, and secures the synchronization message in advance of the projected send time. Securing the synchronization message occurs by suitable cryptographic means allowing for authentication of the time stamp at a receiving slave clock. At the projected send time, the secured synchronization message is transmitted.

  • Patent number: 9998571
    Abstract: Certain aspects of the present disclosure provide techniques and apparatus for using different MAC addresses in frames for the same station to indicate how to process the frames. In this manner, frames for IEEE 802.11ac can carry information not present in legacy frames (e.g., frames according to IEEE 802.11a/n), but these frames may be interpreted by legacy devices in a legacy way. One example method generally includes receiving a first frame comprising an indication of a first MAC address and processing the received first frame based on the first MAC address. For certain aspects, the method further includes receiving a second frame comprising an indication of a second MAC address, wherein the second MAC address is different than the first address; and processing the received second frame based on the second MAC address, such that the processing of the second frame is different than the processing of the first frame.
