An abnormality detection apparatus for a mobility entity and for detecting an abnormality in a network system is provided. The network system includes a first network and a second network that use different communication protocols. A first communication circuit receives state information indicating a state of the mobility entity. The state information is acquired from the second network. A second communication circuit transmits and receives a first frame according to a communication protocol used in the first network. A memory stores an abnormality detection rule. A processor detects, based on the state information and the abnormality detection rule, whether a control command included in the first frame received by the second communication circuit is abnormal. In a case where the control command is abnormal, the processor prohibits the control command from being transmitted.

A system for load-testing a cloud radio access network (C-RAN) is provided. The system includes at least one radio point (RP), each being configured to exchange radio frequency (RF) signals with at least one user equipment (UE). The system also includes a baseband controller communicatively coupled to the at least one RP via a front-haul ETHERNET network. The front-haul ETHERNET network includes at least one switch; and a testing device that is time-synchronized to the baseband controller and the at least one RP. The testing device is configured to receive at least one packet from each of the at least one RP. The testing device is also configured to replicate each of at least some of the received packets to produce a respective replicated packet. The testing device is also configured to transmit at least one replicated packet to the baseband controller.

Systems and methods are disclosed for providing an enhanced Packet Forwarding Control Protocol (PFCP) association procedure for session restoration. In this regard, a method performed by a PFCP node comprises deleting one or more PFCP sessions of the PFCP node that are associated with a failed PFCP entity or with a failed PFCP path. The method further comprises sending, to a PFCP peer node, a node level message to request that the PFCP peer node delete a corresponding one or more PFCP sessions of the PFCP peer node that are associated with the failed PFCP entity or with the failed PFCP path, wherein the node level message comprises an indication of the corresponding one or more PFCP sessions. Some embodiments provide that the node level message comprises a PFCP Association Setup Request including sessions retention information to indicate whether to retain PFCP sessions associated with the PFCP Association Setup Request.

The invention relates to a method for monitoring an industrial ethernet protocol type network. The method comprises the steps of collecting data from the network, using a monitoring device connected to the network, and generating a data file containing the collected data and/or data derived thereof. Further, the method comprises the steps of transmitting the data file to a server, and identifying, using the server, a cause profile associated with the data file.

Provided is a control device that dynamically allocates a virtual network that provides a network service on a physical network by multi-agent deep reinforcement learning, the control device including: selection means for selecting an agent gk that executes an action that represents allocation of the virtual network onto the physical network at a time point t; observation means for observing a state st with an input of network configuration information, network observation information indicating a physical resource amount, and user demand information indicating an amount demanded for a physical resource; allocation means for selecting and executing, on basis of an action value function Q, an action atk from possible actions for the agent gk; reward calculation means for calculating a reward rt at the time point t with use of the action atk, the state st, and a state st+1 at a time point t+1; and learning means for updating the action value function Q with use of the action ajk, the state sj, and the state sj+1, where 1≤j≤t is satisfied.

Disclosed are systems and devices for interfacing media access tuning circuitry that implements collision handling or traffic shaping with a reduced media independent interface (RMII). In some embodiments, an interface circuitry manages emulated signals generated by a media access tuning circuitry in response to detecting that the emulated signals would cause incorrect operation of an RMII. Also disclosed is a physical layer (PHY) device for a multidrop network. In some embodiments the PHY device implements physical layer collision techniques and operable to communicate with a media access control (MAC) device via an RMII, where the MAC is configured for carrier-sense multiple access (CSMA), CSMA with collision detection (CSMA/CD), or CSMA with collision avoidance (CSMA/CA). Also disclosed are processes for managing signaling at a PHY that implements physical layer collision avoidance (PLCA) or traffic shaping, as the case may be.

A smart process control switch can implement a lockdown routine to lockdown its communication ports exclusively for use by devices having known physical addresses, enabling the smart process control switch to prevent new, potentially hostile, devices from communicating with other devices to which the smart process control switch is connected. Further, the smart process control switch can implement an address mapping routine to identify “known pairs” of physical and network addresses for each device communicating via a port of the smart process control switch. Thus, even if a new hostile device is able to spoof a known physical address in an attempt to bypass locked ports, the smart process control switch can detect the hostile device by checking the network address of the hostile device against the expected network address for the “known pair.”

Embodiments relate to including information in a data packet transmitted by a transmitting integrated circuit (e.g., SOC) to account for a time delay associated with an unsuccessful arbitration attempt to send the data packet over a multi-drop bus. The unsuccessful arbitration attempt by the integrated circuit may delay the transmission of the data packet until the multi-drop bus becomes available for the integrated circuit to send the data packet. The data packet includes a data field to include time delay information caused by the unsuccessful arbitration attempt. A receiving integrated circuit may determine the time that the data packet would have been sent out from the transmitting integrated circuit absent the unsuccessful arbitration attempt based on the delay information. Embodiments also relate to a synchronization generator circuit in an integrated circuit that generates timing signals indicating times at which periodic events occur at another integrated circuit.

A system and method for testing of automated contact center customer response systems using a customer response testing system and a real time conversation engine, wherein the customer response testing system generates simulated human queries using persona profiles, sends test cases containing those queries to a contact center under test, and receives and analyzes the responses to determine whether the contact center's automated response systems understand the queries and respond appropriately.

A thermostat and system and method for use of the same are disclosed. In one embodiment, multiple wireless transceivers are located within a housing, which also interconnectively includes a processor, memory, and a camera. To improve convenience, the thermostat may establish a pairing with a proximate wireless-enabled interactive programmable device having a display. Virtual remote control functionality for various amenities may then be provided. To improve safety, the thermostat may be incorporated into a geolocation and safety network and, under certain conditions, the thermostat may provide a video feed.
