  • Patent number: 10541917
    Abstract: A method and system for interacting with data frames passing through a module connected to an industrial network is disclosed. Each module includes an aggregation unit located on the network interface above the physical layer. To transmit data, the aggregation unit reads a header from a dynamic data packet to determine if the module is a participant module for the packet. If so, the aggregation unit inserts data from the module into the data packet and transmits the packet to another module. To receive data, the aggregation unit reads a header from the data packet to determine whether the data packet includes data for the module. If so, the aggregation unit reads the data and passes the data packet to another module. If the aggregation unit determines that a data packet is not intended for the module, the data packet is passed to another module with no further interaction.

  • Patent number: 10542487
    Abstract: An edge device comprising access network discovery and selection function (ANDSF) features is disclosed. An edge device can be a device located at a logical edge of a wireless network. An edge ANDSF component can rank access network resources. The rank can be based on characteristics of an access network resource, a user profile, device resource demands, or a user behavior model. The user profile can comprise information facilitating pre-authentication of a device to an access network resource. Further, the user profile can be considered portable with regard to localized aspects of edge ANDSF components. The user profile provides improved ANDSF feature performance.

  • Patent number: 10536252
    Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a method for sending and receiving information. The user equipment in embodiments of the present invention may determine a frame structure of a serving cell, where in addition to an uplink subframe and a downlink subframe, the frame structure in the embodiments of the present invention further includes a first subframe, and the first subframe includes a first symbol used for downlink transmission, a first GP, and a second symbol used for uplink transmission. More symbols used for downlink transmission and more symbols used for uplink transmission than those in a frame structure in the prior art are introduced by introducing the first subframe, thereby improving downlink transmission and effectively reducing a value of k, that is, reducing a service delay in feeding back a HARQ-ACK.

  • Patent number: 10509625
    Abstract: An electronic device that reduces relative drift is described. In particular, an interface circuit in the electronic device may calculate, based on differences between transmit times when packets were transmitted by a second electronic device and receive times of the packets, relative drift as a function of time between a clock in the interface circuit and a second clock in the second electronic device. Then, the interface circuit may adjust, based on the relative drift, a clock circuit that provides the clock to eliminate the relative drift, and may store the adjustments to the clock circuit. Furthermore, when a wireless reset occurs, the interface circuit may adapt the clock circuit based on the stored adjustments to reduce the relative drift while the interface circuit restores frequency lock with the second clock based on additional packets with additional transmit times that are received from the second electronic device.
