The application layer of a typical industrial communication protocol (such as Profinet, EtherCAT, etc.) usually uses a gatekeeper to enhance the reliability of the communication process and ensure that the message can be delivered within a given survival time (Survival Time). The reliability monitoring mechanism such as the dog, sets a certain number of consecutive packet loss requirements for the application layer messages of industrial communication users, and requires the number of consecutive packet loss times to be lower than a maximum threshold value. The communication link is interrupted; it should be noted that if the watchdog does not receive the expected message within the specified time window, it is considered as packet loss; the watchdog is set at the receiving end. The industrial communication user may be an industrial communication protocol device, such as a programmable logic controller (programmable logic controller, PLC) controller or an industrial computer. As shown in Figure 1. In the 3GPP network, the QoS and reliability guarantee level will be set for users to balance wireless resource consumption and user delay performance. If the guarantee level is too high, the spectrum efficiency will be too low, the wireless resource consumption will be too large, and the entire wireless network will The capacity is too low to meet the scenario of multi-user access; the degree of guarantee is too low, although the overall capacity is increased, but the delay is increased due to multiple retransmissions, and the scenario where the packet has a receiving time window requirement will cause packet loss.

Please refer to Figure 2. In the field of network communication, in order to enhance the reliability of the communication process between industrial communication users and network-side equipment, and ensure that the transmitted data packets can be delivered within a given time, the network-side equipment usually obtains industrial communication User status information to determine the corresponding network configuration for industrial communication users. For example, in the 3rd generation partnership project (3GPP, 3rd generation partnership project) network, the device as the receiving end can use the reliability monitoring mechanism, that is, the watchdog technology to set a certain number of packet loss requirements for the packets of industrial communication users. If the number of packet loss is lower than the threshold, if the corresponding packet is not received within the specified time window, it will be considered as packet loss. If the industrial communication user determines that a message loss has occurred, the industrial communication user can send a specific signaling interaction message, that is, packet loss information, to the core network device separately, thereby notifying the core network device that a message loss has occurred, and the core network device is in the After receiving the packet loss information, it parses out the corresponding message and obtains the status information of the industrial user.

As shown in FIG. 7 , in a possible implementation manner, the network terminal receives status information actively sent by the industrial communication device. Specifically, the status information received by the network terminal from the industrial communication device may be actively sent by the industrial communication device, that is, the industrial communication device has not received the request for obtaining status information sent by the network terminal, and the industrial communication device periodically Send status information to the network terminal periodically or non-periodically, for example, dynamic information can be sent to the network terminal by the industrial communication device after the preset conditions are met, and static configuration information can be sent by the industrial communication device when there is a change after the initial transmission For network terminals, the details are not limited here.

As shown in FIG. 8 , in a possible implementation manner, the network terminal receives status information passively sent by the industrial communication device.

The MAC CE signaling is used to carry the status information of the industrial communication equipment, and the network terminal and the base station equipment There may be multiple interactive communication modes, which are not specifically limited here.

As shown in Figure 10, in a possible implementation manner, when the network side device is a core network device, the network terminal and the base station device can interact through NAS signaling, specifically, the NAS signaling between the network terminal and the base station device Interaction can be based on extensions such as UE-initial NAS transport procedure and UE-initiated UE state indication procedure, or a new container type can be directly extended in uplink NAS direct transmission to transmit information. The core network device may send the state information to the base station device after receiving the state information sent by the network terminal.

Scheduling optimization, such as enabling Grant Free, SPS, pre-scheduling and other features to ensure the delay reliability and determinism (low jitter) of uplink transmission. Correspondingly. The base station equipment can provide the ACK or NACK information of the uplink scheduling by sending the signaling message along with the downlink message or separately, so as to compensate the bottleneck of the reliability of the downlink control channel.

Specifically, for uplink scheduling optimization based on dynamic configuration information, the base station equipment adjusts the uplink scheduling parameters according to the real-time content of the turntable information fed back by the network terminal, according to the different consecutive packet loss times of the watchdog, and sends the adjusted uplink scheduling MCS in real time. And parameters such as redundant transmission to the terminal.

Specifically, the routing and forwarding function module of the network terminal can be set according to the transmission priority of matching packets to ensure that high-priority packets are not preempted, similar to implementing the "slicing" mechanism inside the terminal. The network terminal can also perform scheduling optimization based on information such as message sending cycle, sending start time point, and Watchdog threshold configuration. Submitted to the 3GPP air interface to reduce delay jitter.

For scheduling optimization based on dynamic information: network terminals can be scheduled according to the continuous packet loss status information of Watchdog. Specifically, network terminals can match the number of consecutive packet loss according to the pre-configured strategy to efficiently ensure low-latency and high-reliability data packet transmission ; For example, when it is found that continuous packet loss or Watchdog is at risk of timeout, cooperate with the network side to quickly start the end-side multi-sending and selective receiving function (the sending end copies multiple copies of sending, the receiving end deduplicates and forwards after sorting) function; In the end-to-end wireless scenario, network terminals can perform joint uplink and downlink scheduling optimization based on the continuous packet loss information of Watchdog.
