  • Patent number: 10716033
    Abstract: A method and apparatus for transferring a session from a packet switched access network to a circuit switched access network. A Mobility Management Entity receives a service type indicator from a gateway node. The service type indicator indicates a type of service for the session, and is associated with bearers used for the session. The Mobility Management Entity subsequently receives, from an eNodeB, an indication that the session is to be transferred from the packet switched network to the circuit switched access network. The Mobility Management Entity determines the bearers associated with the session using the service type indicator, and initiates transfer of the session using those bearers. This ensures that the correct bearers are transferred regardless of whether or not identifiers such as QCI values have been ascribed to other types of service.

  • Patent number: 10699231
    Abstract: A graphical workflow definition and management tool enables administrators and other authorized users to implement a workflow process that can be used to evaluate project submissions or other applications that require step-by-step process completion. The steps required to navigate through the workflow are first defined. Inputs, outputs, and actions, including conditional criteria, can be specified for the steps. The flow of control between the individual steps in the workflow is mapped out; changes to the status of a project submission can cause a submission to migrate to a succeeding step in the workflow. A “sandbox” testing environment allows changes to any aspect of the workflow to be safely evaluated without affecting live data. Conflicts between production and test workflows are identified and intelligently resolved.

  • Patent number: 10212617
    Abstract: A method of throughput and data volume measurement for minimization of drive test (MDT) is proposed. A base station establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The base station or UE measures transmitted or received data volume during a transmission time of a data burst between the base station and the UE. When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary. For each measurement period, data volume during the measurement period is measured to generate a measurement result. When throughput measurement is performed by the network, the base station receives location information that is available during the transmission time of the data burst. The data volume measurement is logged with time stamp such that each measurement result can correlated with the location information.

  • Patent number: 10200958
    Abstract: In order to solve a problem in which when a terminal is converted from an active state of transmitting data to an inactive state, the transmission power of the terminal rapidly increases, a base station can control the transmission power by predicting and reflecting, in a target SIR, a decrease in SIR which results from an increase in interference amount due to data transmission of another terminal. The present invention can ensure the quality of an uplink control channel by controlling power in consideration of the effect of interference, even when the terminal is in an inactive state.

  • Patent number: 10142237
    Abstract: A data flow control method and communication device operable to communicate using a first radio access technology (RAT) and a second RAT are described. In a data flow control method, data flow congestion is detected. The congestion can be detected on a first communication link associated with the first RAT. The communication device can be controlled to enter a reduced power operating mode for communications via the first communication link. The entry of the reduced power mode can induce a base station supporting the second communication link associated with the second RAT to perform one or more data flow control operations. A data flow control method can include dropping data packets on a lower protocol layer to induce a higher protocol layer to perform a data flow control operation. The data flow control operation can induce the network to reduce data flow.

  • Patent number: 10129868
    Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.
