The present invention discloses a batch management device for preventing electricity theft in a transformer area based on edge computing, belonging to the technical field of refined operation of power grids. It includes a housing, an electricity theft processing module and a connector assembly. The connector assembly includes an assembly shell, a transition cylinder and a tightening sleeve. The electricity theft processing module is connected to the connector assembly through a wire. Among them, the housing serves as the whole of the device, and the connector assembly for detection is installed on the side wall of the housing. The connector assembly is connected to the electricity meter through a wire clamp. At the same time, the connector assembly inputs the information of the electricity meter and processes it through the electricity theft processing module. Among them, the whole device adopts a connector assembly that can be hot-plugged, which adapts to the needs of various electricity meters. At the same time, it can communicate with multiple electricity meters or even the electricity meters of a transformer area in a carrier mode to read the electricity consumption information data, completing one-to-multipoint communication. The connectors of the connector assembly are diverse and can meet different usage requirements. At the same time, it is convenient to disassemble and install. The whole batch management device for preventing electricity theft adopts an adaptive technology, without too much manual intervention and management.

To provide a method for managing transmission of MBS.SOLUTION: The method is implemented in a CU of a distributed base station including the CU and a DU. The method includes receiving, from a core network (CN), a request to configure resources for transmitting downlink (DL) MBS data associated with an MBS session, determining, based on at least one of (I) capabilities of the DU or (ii) capabilities of UEs that have joined the MBS session, whether the DU is to transmit the MBS data to the UEs on at least one of the air interfaces using a PTP delivery mechanism or a PTM delivery mechanism, and causing the DU to transmit the MBS data according to the determined delivery mechanism.SELECTED DRAWING: Figure 5A

The invention discloses a master-slave vehicle cooperative control method and device. A master vehicle and a slave vehicle establish a point-to-multipoint communication link through a short-distance communication unit. The mother vehicle broadcasts a self motion state containing historical data and a control instruction to the son vehicle through the link; the child vehicle establishes a mother vehicle motion prediction model based on historical data, and monitors a link state in real time through periodic heartbeat communication. And when the child vehicle judges that the link has a fault according to the communication quality parameter, immediately starting the prediction model, calculating the predicted motion state of the mother vehicle according to the finally received effective motion data, continuously executing following control according to the predicted motion state, and attempting to recover the communication at the same time. Under the condition of unstable communication, the child vehicle can autonomously predict and follow the mother vehicle, frequent emergency stop is effectively avoided, and the operation continuity and the system robustness of the vehicle formation in a complex environment are remarkably improved.

The present disclosure describes a point-to-multipoint communication system having a service provider system and one or more subscriber devices. The one or more subscriber devices include multiple physical layer (PHY) devices that can be used for upstream direction and / or downstream direction transfer of information to and / or from the service provider system. The one or more subscriber devices receive subscriber device configuration information from the service provider system indicating which of these multiple PHY devices are to be used for the upstream direction and / or the downstream direction transfer of the information to and / or from the service provider system. In some situations, the subscriber device configuration information identifies various types of information, such as video, audio, and / or data to provide some examples, to be transferred in the upstream direction and / or the downstream direction and / or one or more PHY devices to be used for transferring the various types of information.
