[0026] Below, in conjunction with the accompanying drawings, a communication enhancement method, terminal device and storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0027] As shown in Figure 1, a flow chart of a communication enhancement method provided in an embodiment of the present application is shown. As shown in Figure 1, the communication enhancement method is applied to a link detection system, and the communication enhancement method may include the contents shown in S101 to S102.

[0028] In S101, the link detection system receives service message information sent by a base station.

[0029] The link detection system is an additional system outside the transmission link. It can be integrated into the base station to enhance network stability, or it can use a separate hardware device, including a coupled processor or memory. When using a separate hardware device, the base station and the hardware device can be connected using optical fiber to ensure low latency and high stability of data transmission.

[0030] Among them, the service message information may include Transmission Control Protocol (TCP) service message information and base station information of the base station. The TCP service message information is a message sent by the terminal to the base station using the Data Radio Bearer (DRB). That is, after receiving the TCP service message information sent by the terminal, the base station will add its own base station information to the TCP service message information to obtain the service message information, and then send it to the link detection system. That is, the link detection system receives the service message information containing the base station information of the base station.

[0031] It is worth noting that the base station can be an NR base station or other types of base stations, which is subject to actual application and is not specifically limited in this embodiment. The terminal mainly refers to the TOB network terminal equipment, that is, it is mainly used in the TOB network. Since the TOB network terminal equipment has limited access to message servers and has high requirements for network stability, network fluctuations may cause production activities to be affected, so it is necessary to enhance the stability of the network. The terminal can also refer to the user (To Customer, TOC) network terminal equipment, that is, it can also be applied to the TOC network. In this case, it needs to be deployed on demand. Since the TOC network has many users and accesses to various message servers, too many detection tasks will increase the network load. Therefore, selective deployment is required when applied to the TOC network. In other cases, it can also be applied to other networks, that is, the terminal can also refer to other terminals, which is subject to actual application and is not specifically limited in this embodiment.

[0032] This embodiment uses an NR base station and a TOB network terminal device as an example. The NR base station serves as the access point for the NR device, i.e., the terminal device, and is used to obtain the terminal message information required by the link detection system and receive instructions from the link detection system. The TOB network terminal device can access the NR base station, establish multiple DRBs, and send different service messages.

[0033] As shown in Figure 2, a schematic diagram of a terminal establishing a bearer provided in an embodiment of the present application is shown. The terminal device can send different service message information to a base station, such as an NR base station, through different DRBs, such as drb1, drb2, etc.

[0034] In S102, the transmission link is monitored according to the TCP service message information.

[0035] The transmission link is the path that service message information takes from the terminal to the destination address, for example, the link from the terminal to the core network or server.

[0036] In an embodiment of the present application, a link detection system receives service message information sent by a base station, the service message information including TCP service message information, and monitors a transmission link based on the TCP service message information. The transmission link is the path that the service message information passes through when it is sent from a terminal to a destination address. By adding a link detection system outside the transmission link, the embodiment of the present application analyzes the service message information sent by the base station, and then monitors the transmission link that the service message information passes through when it is sent from a terminal to a destination address, thereby quickly determining whether the entire transmission link has a fault and enhancing the stability of the entire transmission link.

[0037] In a possible implementation of the present application, the TCP service message information is a message sent by the terminal to the base station using the DRB. The TCP service message information may include message delay, that is, the round-trip time (RTT) delay of the service message.

[0038] It is worth noting that TCP service message information includes not only message delay, but also TCP 4-tuple, service message period, and number of service message fragments. The TCP 4-tuple includes source address, source port, destination address, and destination port.

[0039] Accordingly, monitoring the transmission link according to the TCP service message information may include: sending a modification instruction to the base station according to the message delay, where the modification instruction is used to instruct the base station to modify the priority of the DRB.

[0040] It should be noted that there is a one-to-one correspondence between DRBs and TOB network terminal equipment services. Different DRBs are configured with different priorities. Services corresponding to high-priority DRBs can be sent first. Services corresponding to DRBs of the same priority can be sent in the order of service message information.

[0041] In this embodiment, the detection link system may determine the message delay based on the TCP service message information and send an instruction to adjust the priority of the DRB to the base station, thereby adjusting the priority of the service message and enhancing the stability of the network.

[0042] In a possible implementation of the present application, sending a modification instruction to the base station based on the message delay may include: when the message delay exceeds a first delay threshold, sending a modification instruction to the base station to increase the priority of the DRB corresponding to the terminal; when the message delay is lower than a second delay threshold, sending a modification instruction to the base station to lower the priority of the DRB corresponding to the terminal.

[0043] In other words, the link detection system can establish a message model that associates the TCP quadruple and RTT delay to identify the delay between the time when the TOB network terminal device sends a service message and when the base station receives the service message. Based on the RTT delay, the system can issue a scheduling modification instruction.

[0044] The NR base station system receives the scheduling modification instruction from the link detection system and internally modifies the priority of the DRB corresponding to the abnormal terminal service. The NR base station system indicates the modified priority of the DRB to the TOB network terminal device through a reconfiguration message, ensuring that the service corresponding to the DRB can send service messages first, thereby enhancing the stability of the network.

[0045] Among them, the reconfiguration message used by the NR base station system is the Radio Resource Control Protocol Reconfiguration (RRC Reconfiguration) message.

[0046] TCP service message information may also include: the number of service message fragments.

[0047] In this embodiment, when the number of fragments in a service message increases and the RTT delay increases, the link detection system notifies the base station to increase the scheduling resources for the corresponding device. When the number of fragments in a service message decreases and the RTT delay increases, the link detection system notifies the base station to quickly increase the scheduling resources for the corresponding device and initiate a conservative scheduling strategy. When the service message transmission period increases and the RTT delay increases, the link detection system notifies the base station to increase the bearer scheduling priority of the corresponding device. When the service message transmission period decreases and the RTT delay decreases, the link detection system notifies the base station to lower the bearer scheduling priority of the corresponding device. The specific implementation will depend on the actual application and will not be described in detail in this embodiment.

[0048] In a possible implementation manner of the present application, the TCP service message information may include a TCP 4-tuple, and the TCP 4-tuple may include a destination address.

[0049] Accordingly, monitoring the transmission link based on the TCP service message information may include: determining the detection destination address based on the destination address of the TCP quadruple; sending a detection message to the detection destination address and receiving a response message sent by the base station; and determining the delay and / or packet loss rate of the transmission link based on the detection message and the response message.

[0050] That is, a detection task can be established based on the TCP service message information. The detection task may include the detection destination address, the detection period, the total detection duration, and the number of detection messages. The detection destination address is determined based on the destination address in the TCP service message information, the detection period is determined based on the service message period in the TCP service message information, the total detection duration is determined based on the time from when the terminal starts sending the TCP service message information to when the terminal stops sending the TCP service message information, and the number of detection messages is determined based on the above information, that is, the total number of messages counted based on the above information.

[0051] It should be noted that if the terminal is no longer connected to the base station, that is, the base station does not detect the corresponding business message within the business message period, the link detection system will delete the corresponding detection task, automatically increase or decrease the number of detection tasks, reduce workload, and improve detection efficiency. Specifically, the link detection system will identify the message information sent by the base station and establish a detection task. When the corresponding business message is not received for more than a preset number of message sending cycles, the link detection system will delete the corresponding detection task to reduce the network load and issue an equipment communication abnormality alarm. Among them, the preset number can be 5, 6, or other numbers, subject to actual application, and this application does not make specific restrictions.

[0052] The detection message may be a ping (Packet Internet Groper) message.

[0053] In this embodiment, the detection destination address is determined based on the destination address, a detection message is sent to the destination address, and a response message sent by the base station is received. Finally, the delay and / or packet loss rate of the transmission link is determined based on the detection message and response message sent within the total detection time, and then the communication equipment that fails during the communication process is judged, so as to achieve the effect of quickly locating the fault.

[0054] In a possible implementation of the present application, determining the delay and / or packet loss rate of the transmission link based on the probe message and the response message may include: taking the total detection time from the start of the terminal sending the TCP service message information to the end of the terminal sending the message; determining the delay of the transmission link based on the delay between each sending of the probe message and the reception of the response message within the total detection time; determining the packet loss rate of the transmission link based on the amount of probe messages sent and the amount of response messages received within the total detection time.

[0055] The transmission link delay can be the average of the delays between sending a probe message and receiving a response message within the total detection duration, or the median of the delays, or a modified value of the delay, subject to actual application and not specifically limited in this embodiment. The transmission link packet loss rate can be the ratio of the number of probe messages sent to the number of response messages received within the total detection duration, or a modified value, subject to actual application and not specifically limited in this embodiment.

[0056] In other words, the delay between each probe message sent and the corresponding response message received can be recorded to determine the transmission link latency. The packet loss rate of the transmission link can be determined based on the number of probe messages sent and the number of response messages received within the total probe duration. This can then be used to identify the communication device that experienced a fault, allowing for rapid fault location.

[0057] In a possible implementation manner of the present application, the TCP service message information includes base station information of the base station.

[0058] Accordingly, monitoring the transmission link according to the TCP service message information may include: determining a fault location where the transmission link fails according to the base station information.

[0059] The base station information may include at least one of a global identifier (NR Cell Global, NCGI), a tracking area code (Tracking Area Code, TAC) and a terminal device ID of the terminal.

[0060] In other words, the link detection system can quickly locate the fault location based on base station information, and then take corresponding measures or issue early warnings to improve the stability of the entire transmission link.

[0061] It is worth noting that a transmission link failure may include a transmission link delay exceeding a preset delay, a transmission link packet loss rate exceeding a preset packet loss rate, or other failures, subject to actual application and not specifically limited in this embodiment. The preset delay may be determined based on historical data or other circumstances, subject to actual application and not limited in this embodiment. The preset packet loss rate may be determined based on historical data or other circumstances, subject to actual application and not limited in this embodiment.

[0062] In one possible implementation of the present application, the base station information includes at least one of a global identifier (NR Cell Global, NCGI), a tracking area code (Tracking Area Code, TAC) and a terminal device ID of the terminal.

[0063] The terminal device ID is the Radio Network Temporary Identifier (RNTI) assigned to a terminal device, such as a TOB network terminal device, when it accesses a base station. NCGI is used to globally identify a cell, and TAC is used to divide base stations with similar physical locations.

[0064] That is to say, after receiving the service message sent by the terminal, the base station adds the information marking the base station in the service message before sending it to the link detection system, that is, adds its own base station information to the checksum field in the TCP service message, so that the link detection system can determine the fault location.

[0065] Accordingly, determining the fault location of the transmission link failure based on the base station information may include: in the event of a transmission link failure, determining the fault location of the failure based on at least one of the base station's global identifier, tracking area code, and terminal device ID of the terminal.

[0066] Specifically, by comparing the delays of service messages sent by different terminal device IDs under the same NCGI, when it is detected that the delay of an individual terminal device has increased, it can be determined that the terminal device has failed, or the environment in which the device is located has changed, or there is sudden interference. By comparing the delays of service messages of different NCGIs under the same TAC area, when it is detected that the delay of service messages of all terminal devices under a certain NCGI has increased, it can be determined that there is a problem with the base station processing. By comparing the delays of service messages in different TAC areas, when it is detected that the overall service message delay of a certain TAC area is higher than that of other TAC areas, it can be determined that there is a problem with some transmission equipment in the area, resulting in a failure in the transmission link from the base station to the core network. When it is detected that the RTT delay of all areas has increased or even packet loss, combined with the results of the detection task, it can be determined that there is a problem with the service message server or the core network. In other words, the link detection system can distinguish each network node by comparing the extracted information to quickly locate the location of the fault.

[0067] As shown in Figure 3, it is a flowchart of the fault location determination logic provided by the embodiment of the present application. The specific determination logic is as follows:

[0068] Obtain business message information to establish a detection task. When the RTT in the business message increases, determine whether there is a problem with an individual terminal. If there is a problem with an individual terminal, determine that the terminal is faulty or there is sudden interference. Otherwise, determine whether the terminal device is in the same NCGI. If so, it means that there is an abnormality in the base station. Otherwise, further determine whether the base station is in the same TAC area. If so, it means that there is an abnormality in the transmission link of the TAC area. Otherwise, further determine whether there is an abnormality in all TAC areas. If so, it means that there is an abnormality in the core network forwarding. Otherwise, further determine whether there is an abnormality in the detection result. If there is an abnormality, it means that the server is abnormal. Finally, output the judgment result to the base station.

[0069] This embodiment uses unified regional message processing to separate the nodes of the transmission link and determine whether the fault comes from the network terminal equipment, a single base station system, or a regional commonality, thereby achieving the effect of quickly locating the fault.

[0070] As shown in Figure 4, a flow chart of another communication enhancement method provided in an embodiment of the present application is shown. As shown in Figure 4, the communication enhancement method is applied to a base station, and the communication enhancement method may include the contents shown in S401 to S402.

[0071] In S401, the service message information is sent to the link detection system.

[0072] The service message information includes TCP service message information.

[0073] That is, when the base station receives the service message information sent by the terminal, it sends the service message information to the link detection system, and the link detection system can monitor the transmission link according to the service message information.

[0074] In S402, an instruction from a link detection system is received.

[0075] The link detection system monitors the transmission link based on the service message information. If there is an abnormality in the transmission link, it can send an instruction to the base station so that the base station can take corresponding measures to enhance the stability of the transmission link.

[0076] In an embodiment of the present application, the base station sends service message information to a link detection system and receives an instruction from the link detection system. By adding a link detection system outside the transmission link, the present application embodiment analyzes the service message information sent by the base station, and then monitors the transmission link through which the service message information is sent from the terminal to the destination address. If there is an abnormality in the transmission link, an instruction can be sent to the base station, which can quickly determine whether the entire transmission link has failed, thereby enhancing the stability of the entire transmission link.

[0077] In a possible embodiment of the present application, before sending the service message information to the link detection system, the communication enhancement method may also include: receiving TCP service message information sent by the terminal using the data radio bearer DRB; adding the base station information of the base station to the TCP service message information to obtain the service message information, and the base station information includes a global identifier, a tracking area code and at least one of the terminal device ID of the terminal.

[0078] There is a one-to-one correspondence between DRBs and terminal services. Different DRBs are configured with different priorities. Services corresponding to higher-priority DRBs receive priority in sending service messages. Services corresponding to DRBs of the same priority receive messages in the order in which they were sent. The terminal device ID is the RNTI assigned to a terminal device when it accesses a base station in a TOB network. NCGI is used to globally identify a cell, and TAC is used to classify base stations with similar physical locations.

[0079] That is to say, after receiving the service message sent by the terminal, the base station adds the information marking the base station to the service message before sending it to the link detection system, that is, adds its own base station information to the Checksum field in the TCP service message, so that the link detection system can determine the fault location.

[0080] In a possible implementation of the present application, receiving an instruction from a link detection system may include: receiving a modification instruction sent by the link detection system and modifying the priority of the DRB according to the modification instruction; and / or receiving a fault location sent by the link detection system.

[0081] That is, the base station receives the scheduling modification instruction from the link detection system and internally modifies the priority of the DRB corresponding to the abnormal terminal service. The base station indicates the modified priority of the DRB to the terminal through a reconfiguration message, ensuring that the service corresponding to the DRB can send service messages first.

[0082] Among them, the reconfiguration message used by the NR base station system is the RRC Reconfiguration message.

[0083] This embodiment can adjust the priority of DRB according to the instructions of the link detection system, and then adjust the priority of the service message to enhance the stability of the network. It can also take corresponding measures or warnings according to the fault location sent by the link detection system to improve the stability of the entire transmission link.

[0084] In a possible embodiment of the present application, before the receiving terminal uses the data radio bearer DRB to send TCP service message information, the communication enhancement method may also include: receiving an access request from the terminal; upon receiving the access request, establishing a data radio bearer DRB, and instructing the terminal to use the DRB to send TCP service message information.

[0085] That is to say, before the base station receives the TCP service message information sent by the terminal using the DRB, the base station receives an access request from the terminal, establishes a quality of service (QoS) flow and maps it to the DRB. Specifically, as shown in Figure 5, taking the base station as an NR base station and the terminal as a TOB network terminal device as an example, the NR base station receives an access request from the TOB network terminal device and sends it to the core network. The core network establishes multiple QoS flows and sends them to the NR base station. The NR base station establishes a DRB based on the QoS flow information. The DRB corresponds to the QoS flow one-to-one. When sending service messages, the TOB network terminal device also needs to use the corresponding DRB to send messages according to the base station definition. Among them, the base station definition method is to notify the terminal of the established DRB through the RRC Reconfiguration message. The DRB carries the scheduling priority and the ID of the QoS flow corresponding to the bearer. Different QoS flow rules are notified to the terminal through the protocol data unit to establish a session reception response (PDU session establishment accept). The QoS flow rules include the ID of the QoS flow and the filtering rules of the service message, such as protocol filtering, port filtering, path filtering, etc.

[0086] Among them, the terminal can send service messages to the base station through the wireless link shown in Figure 2. The terminal may not be a device that directly sends messages. The terminal may also be a device that has the ability to send NR wireless signals and has a routing function. Other terminals access the device through wired or wireless access and then send messages through the device.

[0087] As shown in Figure 5, it is a detailed flow chart of the communication enhancement method provided in an embodiment of the present application. Take the terminal as a TOB network terminal device and the base station as an NR base station system as an example.

[0088] The TOB network terminal device sends an access request to the NR base station system. After receiving the access request, the NR base station system sends it to the core network. The core network establishes multiple qos flows and sends the multiple qos flows to the NR base station system. The NR base station system establishes multiple drbs corresponding to the qos flows, and instructs the TOB terminal device to use drbs to send TCP service message information. The TOB terminal device uses drbs to send TCP service message information to the NR base station system. After receiving the TCP service message information, the NR base station system sends the TCP service message information to the core network. After adding the NR base station system information to the TCP service message information, the service message information is obtained and sent to the link detection system. The link detection system identifies the service message information, establishes a message model and a detection task. The message model is used to determine the delay and sends a scheduling instruction to the NR base station system based on the delay. The NR base station system modifies the priority of the DRB according to the scheduling instruction and sends the modified priority to the TOB terminal device to instruct the TOB terminal device to use the modified DRB to send the service message. The detection task is used to determine the fault point. The link detection model sends a detection message to the core network according to the detection task, and then receives a response message to the detection message sent by the NR base station system. The link detection system obtains the detection result, that is, the fault point, based on the response message and sends the detection result to the NR base station system. The NR base station system processes or warns based on the detection result. If it is a problem with itself, it will perform corresponding processing. If it is a problem with the message server or the core network, it will issue a warning.

[0089] Among them, the NR base station system sends the TCP service message information sent by the TOB terminal device to the core network through the standard N3 interface, and the core network continues to forward the TCP service message information to the operator data network through the N6 interface, and then reaches the message server through the wired link. In other embodiments, the NR base station system does not send messages to the core network, but directly sends the TCP service message information to the message server through a wired or wireless link. The specific application shall prevail, and this embodiment is not limited.

[0090] It is worth noting that the link detection system can be integrated into the NR base station system to enhance network stability, or it can use a separate hardware device, including a coupled processor or memory, where the memory is used to store link detection tasks and the processor is used to send and receive messages and issue scheduling instructions. When the link detection system uses a separate hardware device, the NR base station system and the hardware device are connected using an optical fiber to ensure low latency and high stability of data transmission.

[0091] FIG6 is a schematic diagram of the network structure provided by this embodiment.

[0092] The TOB network includes base stations 1, 2, and 3, as well as terminals 1, 2, and 3 connected to the base stations. The base stations communicate with a link detection system and the core network, and the link detection system sends detection information to the core network. This has been described in detail in the previous embodiments and will not be repeated in this embodiment.

[0093] As shown in FIG7 , a schematic diagram of the structure of a communication enhancement system provided in an embodiment of the present application is shown. The communication enhancement system is applied to a link detection system and may include: a first receiving module 701 and a monitoring module 702 .

[0094] Among them, the first receiving module 701 is used to receive business message information sent by the base station, and the business message information includes Transmission Control Protocol TCP business message information; the monitoring module 702 is used to monitor the transmission link based on the TCP business message information, and the transmission link is the path through which the business message information is sent from the terminal to the destination address.

[0095] In an embodiment of the present application, first, a first receiving module 701 receives service message information sent by a base station, the service message information including TCP service message information. Then, a monitoring module 702 monitors a transmission link based on the TCP service message information. The transmission link is the path that the service message information travels through when it is sent from a terminal to a destination address.
