Detailed Description

In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application, and it is obvious that the described embodiments are some but not all of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The private network in the embodiment of the present application may include, but is not limited to: a fifth generation mobile communication technology (5th generation mobile communication technology, 5G) private network, a 4G private network, and the like. The following description will be given by taking a 5G private network as an example. Fig. 1 is a schematic view of a scenario in which the method for data transmission in a private network according to the embodiment of the present application is applied. Referring to fig. 1, the private network scenario may include: the system comprises a terminal, network equipment, a core network element and a server. It should be understood that the private network scenario illustrated in fig. 1 does not constitute a specific limitation to the private network scenario. In other embodiments of the present application, a private network scenario may include more or fewer devices than shown, or some devices may be combined, some devices may be split, or a different arrangement of devices.

The terminal in this embodiment may be referred to as a User Equipment (UE), for example, the terminal may be a mobile phone, a tablet computer (PAD), a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device, a wearable device, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), and the like, and a form of the terminal is not particularly limited in this embodiment.

Private networks are different and network devices are different. For example, in a 5G private network, the network devices may be, but are not limited to: a base station, a next generation base station (which may be collectively referred to as a new generation radio access network node (NG-RAN node)). The next generation base station may include a new air interface base station (NR nodeB, gNB), a new generation evolved base station (NG-eNB), a Central Unit (CU), a Distributed Unit (DU), a gNB in a separate form), or other nodes.

Core network elements include, but are not limited to: a User Plane Function (UPF) network element, an edge computing technology (MEC) network element, a 5G core control plane (5 GC-CP) network element, and a unified data management function (UDM) network element. In an embodiment, the core network element may further include more or fewer network elements, which is not limited in this embodiment of the present application.

The UPF is mainly responsible for routing and forwarding data packets externally connected to a Data Network (DN) and a user plane, filtering packets, and performing quality of service (QoS) control related functions. The MEC is used for deploying services with high-density calculation, large flow and low time delay requirements, and meets multiple requirements of users on safety, speed and reliability. The 5GC-CP is used to assist in the transmission of user plane data. The UDM is used to manage control plane data and user plane data. The functions of the network elements involved in the embodiment of the present application may also refer to related descriptions in the existing 5G private network, which are not described herein again.

The server side can comprise: a server or a cluster of servers. In the following embodiments, a server is taken as an example for explanation.

The following describes a data transmission process from a terminal to a server in a private network scenario with reference to the private network scenario shown in fig. 1. When the terminal transmits data to the server, the terminal can send the data to the network device, and after receiving the data, the network device can send the data from the terminal to the UPF. After receiving the data, the UPF may send the data to the server. In an embodiment, data sent by the terminal to the server may be referred to as uplink data, and the uplink data may be service data. In one embodiment, upstream data may be sent in the form of data packets.

In order to ensure the reliability of data transmission in the private network, in the private network scenario, a plurality of network devices may be configured for the terminal to serve. Illustratively, as shown in fig. 2, both the first network device and the second network device serve as terminals, and it should be understood that fig. 2 illustrates two network devices as an example. In one embodiment, the first network device or the second network device may be a master network device and the other network device is a standby network device. It should be understood that the devices in the private network involved in the embodiments of the present application are shown in fig. 2, and the MEC, 5GC-CP, and UDM are not shown.

Referring to fig. 2, in an embodiment, a process of sending data from a terminal to a server may be as follows:

when transmitting data, the terminal can copy the data (indicated by packet 1 in fig. 2) into two copies. The terminal sends one of the data to the first network equipment and sends the other data to the second network equipment. The first network device may send data to the UPF after receiving the data, and similarly, the second network device may send data to the UPF after receiving the data. Thus, the UPF needs to receive data from all network devices serving the terminal, e.g., the UPF can receive two identical pieces of data from the terminal. In one embodiment, the UPF may send the data received first to the server, or the UPF may select any of the data to send to the server.

It should be understood that the scenarios in the embodiment of the present application are: the first network device and the second network device serve a scenario of one terminal. In one embodiment, although the private network provides the first network device and the second network device for the terminal to serve, in order to save energy consumption of the network devices, only one network device serves the terminal at the same time, and when one network device fails, the other network device can be started to serve the terminal. For example, when the first network device serves the terminal, the second network device may be in a sleep state with low power consumption, as shown in a in fig. 3. And when the first network device fails and cannot transmit data for the terminal, the second network device may be started to transmit data for the terminal, as shown in b in fig. 3. Fig. 3 illustrates the data packet 1 as an example.

In the data transmission shown in fig. 3, when the first network device fails, data cannot be transmitted for the terminal, that is, in a process from the failure of the first network device to the start of the second network device, no network device transmits data for the terminal, and data transmission of the terminal is interrupted, which results in a large data transmission delay of the terminal. It should be understood that the embodiment of the present application is proposed based on the scenario shown in fig. 3.

In order to solve the above problem, an embodiment of the present application provides a method for data transmission in a private network, where when a network device serving a terminal has a probability of failure, that is, when the network device does not have a failure but performance of data transmission is reduced (or transmission quality is poor), a second network device is started in advance, so that a first network device and the second network device transmit data from the terminal together, so that data transmission of the terminal is not interrupted, and further, a time delay of data transmission is reduced.

It should be understood that the following embodiments are described by taking the implementation subject of the method for performing data transmission in the private network as an example of the decision device. In one embodiment, the decision device may be a first network device, a second network device, or other separately configured devices, and the following embodiments are described by taking the decision device as a separately configured device as an example.

The following describes a method for data transmission in a private network according to an embodiment of the present application with reference to a specific embodiment. The following several embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes. Fig. 4 is a flowchart illustrating a method for data transmission in a private network according to an embodiment of the present application. Fig. 4 illustrates a method for transmitting data in a private network according to an embodiment of the present application in terms of interaction between a terminal, a decision device, network devices (a first network device and a second network device), a UPF, and a server.

As shown in fig. 4, a method for data transmission in a private network according to an embodiment of the present application may include:

s401, the terminal sends first data to the first network equipment.

It should be understood that, in the embodiment of the present application, the terminal sends the first data to the server through the first network device and the UPF. The second network device is in a dormant state.

S402, the first network equipment sends first data to the server through the UPF.

S401-S402 characterize that the terminal transmits data to the server side through a network device serving the terminal. In one embodiment, the first network device may be a primary network device.

And S403, in response to the fact that the transmission reliability parameter value of the first network device is lower than the preset parameter value, the decision device detects whether the terminal supports simultaneous data transmission to multiple network devices.

It should be understood that S403 is not sequentially distinguished from S401 to S402, and in this embodiment, the example that after S402, the decision device detects that the transmission reliability parameter value of the first network device is lower than the preset parameter value is described.

The transmission reliability parameter of the first network device may comprise at least one of: bit error rate, transmission rate, and transmission delay of the first network device. The transmission reliability parameter value of the first network device is a numerical value of the transmission reliability parameter of the first network device. The transmission reliability parameter value of the first network device is used to characterize the transmission reliability of the first network device. For example, the lower the bit error rate of the first network device, the higher the transmission reliability of the first network device, the faster the transmission rate of the first network device, the higher the transmission reliability of the first network device, the smaller the transmission delay of the first network device, and the higher the transmission reliability of the first network device.

In one embodiment, the decision device may detect the transmission reliability parameter value of the first network device in real time or in a surrounding manner.

In one embodiment, when the decision device is a first network device, the first network device may obtain its own transmission reliability parameter value. In an embodiment, when the decision device exists independently from the first network device, the first network device may obtain a transmission reliability parameter value of itself, and send the transmission reliability parameter value of the first network device to the decision device, so that the decision device may obtain the transmission reliability parameter value of the first network device.

The decision device stores a preset parameter value, and the preset parameter value represents that the transmission reliability of the first network device has a risk, that is, the transmission reliability of the first network device can ensure that the first network device transmits data, but the transmission reliability is reduced. It can also be said that the preset parameter value indicates that the first network device has not failed, but the probability of failure is high.

The decision device determines that the transmission reliability of the first network device is at risk in response to detecting that the transmission reliability parameter value of the first network device is lower than a preset parameter value, so that different data transmission modes can be provided for the terminal based on the type of the terminal. The types of the terminals related to in the embodiment of the present application include: the terminal may support the simultaneous transmission of data to multiple network devices and the terminal may not support the simultaneous transmission of data to multiple network devices.

Therefore, the decision device may detect whether the terminal supports simultaneous data transmission to multiple network devices in response to detecting that the transmission reliability parameter value of the first network device is lower than a preset parameter value.

In an embodiment, when the private network provides the first network device and the second network device for the terminal service, the terminal may report the terminal information to the first network device and the second network device, where the terminal information may include: the type of the terminal, i.e. whether or not it supports simultaneous data transmission to multiple network devices. Thus, in this embodiment, the decision device may obtain the information of the terminal by requesting the first network device, so as to detect whether the terminal supports data transmission to multiple network devices simultaneously.

In an embodiment, when the private network provides the first network device and the second network device for the terminal service, the terminal may report the terminal information to the decision device, where the terminal information may include: the type of terminal.

S404, if the terminal supports data transmission to a plurality of network devices at the same time, the decision device starts a second network device.

If the terminal supports data transmission to multiple network devices at the same time, the decision device may start the second network device to provide the first network device and the second network device for the terminal service, so as to ensure reliability of data transmission of the terminal.

In one embodiment, the decision device initiating the second network device may be understood as: and the decision-making equipment sends a starting instruction to the second network equipment. And when the second network equipment receives the starting instruction, the second network equipment can be switched from the dormant state to the working state to serve the terminal. It should be understood that fig. 4 illustrates an example where the decision device sends the start instruction to the second network device.

S405, the decision device sends first information to the terminal.

The first information is used for instructing the terminal to send the same data to the first network device and the second network device. That is, the decision device may send the first information to the terminal to notify the terminal to send the same data to the UPF through the first network device and the second network device, so that the UPF selects one of the data to send to the server, and may transmit the data of the terminal by referring to the method shown in fig. 2.

S406, the terminal copies the second data into two copies.

S407, the terminal sends one of the second data to the first network device.

S408, the terminal sends another second data to the second network equipment.

It should be understood that S407 and S408 are not sequentially distinguished, and may be performed simultaneously.

For example, the second data may be regarded as a data packet 1, and a process of the terminal sending the second data to the UPF through the first network device and the second network device may refer to the relevant description in fig. 2. It should be understood that the process of transmitting the second data among the first network device, the second network device, the UPF and the server is not shown in fig. 4.

Taking the first data as the data packet 1 and the second data as the data packet 2 as an example, referring to a in fig. 5, if the terminal sends the data packet 1 to the UPF through the first network device, the UPF may send the data packet 1 to the server. Referring to b in fig. 5, when the transmission reliability parameter value of the first network device is lower than the preset parameter value, the decision device may start the second network device and send the first information to the terminal. After receiving the first information, the terminal may send the same data, such as data packet 2, to the first network device and the second network device.

In the method for data transmission in a private network provided by the embodiment of the application, the decision device detects whether the terminal supports data transmission to multiple network devices simultaneously in response to detecting that the transmission reliability parameter value of the first network device is lower than a preset parameter value. And if the terminal supports data transmission to a plurality of network devices at the same time, starting the second network device, and sending first information to the terminal to indicate the terminal to send the same data to the first network device and the second network device. In the embodiment of the application, when the first network device is not in fault but in the presence of a risk of reliable transmission of the first network device, that is, when the network device is not in fault but the performance of data transmission is reduced, the second network device is started in advance, so that the first network device and the second network device jointly transmit data from the terminal, the data transmission of the terminal is uninterrupted, and the time delay of data transmission is further reduced.

In one embodiment, in order to further ensure reliability of data transmission, before the terminal uses the second network device to formally transmit data, the terminal may first test the transmission quality of the second network device, and when the transmission quality of the second network device is higher (e.g., greater than a preset quality), the terminal uses the first network device and the second network device to simultaneously transmit the same data to the UPF.

In this embodiment, the first information sent by the decision device to the terminal is used to indicate: the terminal sends the same data to the first network equipment and the second network equipment, and marks the data sent to the second network equipment as test data. For example, the data sent by the terminal to the first network device and the second network device are both the second data, and in an embodiment, the second data is service data.

The terminal may send second data (the second data being traffic data) to the first network device and may send the second data (identified as test data) to the second network device.

Referring to fig. 6, S408 in the above embodiment may be replaced with S601:

s601, the terminal identifies another piece of second data as test data and sends the identified second data to the second network equipment.

The purpose of the terminal for identifying the other piece of second data as the test data is as follows: and instructing the second network equipment to test and acquire the transmission quality of the second network equipment based on the second data.

After S601, the method may further include:

s602, the decision device obtains the transmission information of the data which is transmitted and identified as the test data by the second network device.

After the terminal sends the second data identifier as the test data to the second network device, the decision device may obtain transmission information of the second data identifier as the test data transmitted by the second network device, that is, the decision device may obtain the transmission information of the second network device based on the second network device receiving the second data identifier as the test data. Wherein the transmission information comprises at least one of: bit error rate, transmission rate, and transmission delay.

S603, the decision device obtains the transmission quality of the second network device relative to the terminal according to the transmission information.

In other words, the terminal sends the second data identified as the test data to the second network device in order to obtain the transmission information, and then obtains the transmission quality of the second network device based on the transmission information.

In the embodiment of the present application, the decision device obtains, according to the transmission information, transmission quality of the second network device with respect to the terminal (in the following embodiment, simply referred to as transmission quality). It should be understood that the transmission quality of the second network device with respect to the terminal refers to: transmission quality when the second network device transmits data from the terminal. The decision device may obtain the transmission quality based on a value (i.e., a parameter value) of a parameter included in the transmission information.

In an embodiment, the decision device stores a mapping relationship between the value of each parameter and the transmission quality, and the decision device may obtain the transmission quality based on the value of each parameter in the transmission information and the mapping relationship. Illustratively, taking the example that the transmission information includes the bit error rate, when the value of the bit error rate is within a first preset range, the transmission quality is a first transmission quality, and when the value of the bit error rate is within a second preset range, the transmission quality is a second transmission quality, and the first transmission quality is higher than the second transmission quality.

In one embodiment, the decision device may also determine the range of transmission quality based on the values of the parameters in the transmission information. Illustratively, taking the bit error rate as an example, when the value of the bit error rate is within a first preset range, the transmission quality is greater than or equal to the first preset transmission quality, and when the value of the bit error rate is within a second preset range, the transmission quality is less than the second preset transmission quality.

It is to be understood that the first predetermined transmission quality and the second predetermined transmission quality are predetermined, the first predetermined transmission quality being higher than the second predetermined transmission quality.

Table one is a mapping relation of the values of each parameter with the transmission quality:

watch 1

As in the first table above, for example, when the bit error rate is in the range of a1-a2, the transmission rate is in the range of B1-B2, and the transmission delay is in the range of C1-C2, the transmission quality of the second network device with respect to the terminal is greater than or equal to the first preset transmission quality.

In one embodiment, the decision device may also detect a time when the first network device receives the second data from the terminal, e.g., T1. If the decision device detects that the second network device does not receive the second data from the terminal within the preset verification time window after T1, the decision device may determine that the transmission quality is less than a second preset transmission quality.

When the decision device is set independently from the first network device and the second network device, the first network device may send a message of completing receiving the second data to the decision device in response to receiving the second data from the terminal, and similarly, the second network device may send a message of completing receiving the second data to the decision device in response to receiving the second data from the terminal. In this way, the decision device may regard the time when the message is received as the time T1 when the first network device receives the second data from the terminal, and within the preset verification time window after T1, if the decision device does not receive the message that the second network device completes receiving the second data, it may determine that the second network device does not receive the second data within the preset verification time window after T1. If within the predetermined verification time window after T1, the decision device receives a message from the second network device that the second data reception is complete, it may be determined that the second network device received the second data within the predetermined verification time window after T1.

When the decision device is the first network device, the second network device may send a message of completing receiving the second data to the first network device in response to receiving the second data from the terminal. The first network device may record the received time T1 in response to receiving the second data from the terminal, and may determine that the second network device has not received the second data within the preset verification time window after T1 if the first network device does not receive the message of completing the reception of the second data from the second network device within the preset verification time window after T1. If within the preset verification time window after T1, the first network device receives a message from the second network device that the second data reception is complete, it may be determined that the second network device did not receive the second data within the preset verification time window after T1.

The scenario where the decision device is the second network device may refer to the above-mentioned description of "when the decision device is the first network device".

And S604, determining a target mode of sending data to the UPF by the terminal according to the transmission reliability parameter value and the transmission quality by the decision equipment.

The transmission reliability represents the reliability of the first network device for transmitting the data from the terminal, and the higher the transmission reliability is, the more the smooth transmission of the data from the terminal can be ensured. The transmission quality represents the reliability of the data transmitted from the terminal by the second network device, and the higher the transmission quality is, the more the smooth transmission of the data from the terminal can be ensured.

In one embodiment, the target mode includes any one of: a first transmission mode, a second transmission mode, a third transmission mode and a fourth transmission mode. Wherein, the first transmission mode is as follows: the terminal sends data to the UPF through the first network equipment, and the second transmission mode is as follows: the terminal sends data to the UPF through the second network device, and the third transmission mode is as follows: the terminal sends the same data to the UPF through the first network device and the second network device, and the fourth transmission mode is: the terminal selects target network equipment from the first network equipment and the second network equipment, and sends data to the UPF through the target network equipment.

It should be noted that the fourth transmission mode is a target network device that is determined by the terminal itself to send data to the UPF. In one embodiment, the target network device is a master network device, such as a first network device, or a second network device, or both a first network device and a second network device. In one embodiment, the target network device is pre-provisioned. In other words, when the target mode is the fourth transmission mode, the terminal sends data to the UPF according to the appointed network device (i.e. the target network device).

In this embodiment, the decision device may obtain the level of the transmission reliability of the first network device according to the transmission reliability parameter value, and further determine a target mode in which the terminal sends data to the UPF according to the level of the transmission reliability and the transmission quality. The higher the level of the transmission reliability is, the higher the representation transmission reliability is, that is, the more the smooth transmission of the data from the terminal can be ensured.

In one embodiment, the level of transmission reliability may be divided into a first level and a second level, the first level being higher than the second level. When the transmission reliability is of a first grade, the risk of representing the transmission reliability of the first network device is small, and when the transmission reliability is of a second grade, the risk of representing the transmission reliability of the first network device is large. In addition, the decision device may pre-store a first preset quality and a second preset quality, and further divide the transmission quality into three levels, where the first preset quality is greater (or higher) than the second preset transmission quality.

Based on the above classification of the transmission reliability level and the transmission quality, the following teaching is made to determine the manner in which the terminal transmits data to the UPF by the decision device:

first, if the level of the transmission reliability is a first level and the transmission quality is less than a second preset transmission quality, the decision device determines that the target mode is a first transmission mode.

Secondly, if the level of the transmission reliability is the first level and the transmission quality is greater than or equal to the first preset transmission quality, the decision device determines that the target mode is the third transmission mode.

And thirdly, if the level of the transmission reliability is the second level and the transmission quality is greater than or equal to the second preset transmission quality, the decision equipment determines that the target mode is the second transmission mode.

And fourthly, if the level of the transmission reliability is the second level and the transmission quality is less than the second preset transmission quality, the decision equipment determines that the target mode is the fourth transmission mode.

And S605, the decision equipment sends fifth information to the terminal, wherein the fifth information is used for indicating the terminal to send data to the UPF in a target mode.

Corresponding to the first one in S605, the fifth information is used to instruct the terminal to send data to the UPF in the first transmission mode, that is, instruct the terminal to send data to the UPF through the first network device. In this manner, when the decision device sends the fifth information to the terminal, the first warning information may be further output, where the first warning information is used to indicate that the second network device is poor in transmission quality and unavailable.

In one embodiment, the manner in which the decision device outputs the first warning information may include, but is not limited to: the decision device displays a text prompt message of 'the transmission quality of the second network device is poor or the second network device is unavailable', or the decision device plays a voice of 'the transmission quality of the second network device is poor or the second network device is unavailable', and then a manager of the network device is reminded.

Corresponding to "two thereof" in S605, the fifth information is used to instruct the terminal to send data to the UPF in the third transmission mode, that is, instruct the terminal to send data to the UPF through the first network device and the second network device, and notify the terminal that the service data does not need to be identified as the test data.

Corresponding to "third of S605, the fifth information is used to instruct the terminal to send data to the UPF in the second transmission mode, that is, instruct the terminal to send data to the UPF through the second network device. In this manner, when the decision device sends the fifth information to the terminal, the second warning information may be further output, where the second warning information is used to indicate that the transmission reliability of the first network device is low and the first network device is unavailable.

Corresponding to "the fourth of S605, the fifth information is used to instruct the terminal to select a target network device from the first network device and the second network device, and to send data to the UPF through the target network device, that is, instruct the terminal to send data to the UPF through a predetermined target network device. In this manner, when the decision device sends the fifth information to the terminal, the decision device may further output third warning information, where the third warning information is used to indicate that the transmission reliability of the first network device is low, the transmission quality of the second network device is poor, and for example, the level of the transmission reliability of the first network device is the second level, and the transmission quality of the second network device is smaller than the second preset transmission quality.

The mode of the decision device outputting the second alarm information and the third alarm information may refer to the relevant description of the first alarm information.

And S606, the terminal sends data to the UPF in a target mode.

Referring to fig. 6, when the fifth information is used to instruct the terminal to transmit data to the UPF in the first transmission mode, the terminal may transmit data to the UPF through the first network device.

And when the fifth information is used for indicating the terminal to send data to the UPF by adopting a third transmission mode, the terminal can send data to the UPF through the first network equipment and the second network equipment.

And when the fifth information is used for indicating the terminal to send data to the UPF by adopting the second transmission mode, the terminal can send the data to the UPF through the second network equipment.

When the fifth information is used to instruct the terminal to select a target network device from the first network device and the second network device, the terminal may send data to the UPF through a predetermined target network device.

In the embodiment of the application, when the decision device detects that the transmission reliability parameter value of the first network device is lower than the preset parameter value and the terminal supports data transmission to multiple network devices at the same time, in order to ensure the transmission reliability of the terminal data, before the terminal adopts the second network device to formally transmit the data, the transmission quality of the second network device may be tested first, and when the transmission quality of the second network device is higher (if the transmission quality is higher than the preset quality), the terminal simultaneously adopts the first network device and the second network device to send the same data to the UPF, so that smooth transmission of the terminal data can be ensured.

In the above embodiment, which explains an example that the terminal supports simultaneous data transmission to a plurality of network devices, and the following embodiment explains a method that the terminal does not support simultaneous data transmission to a plurality of network devices, referring to fig. 7, S701 to S709 may be further included after S403 as above. It should be understood that S701-S709 and S404-S408 are alternatively performed steps, and FIG. 7 is an addition of S701-S709 to FIG. 4, and in one embodiment, S701-S709 may also be added to the illustration shown in FIG. 6.

And S701, if the terminal does not support simultaneous data transmission to a plurality of network devices, the decision device sends second information to the terminal.

Accordingly, the terminal may receive the second information.

In an embodiment, if the terminal does not support simultaneous data transmission to multiple network devices, the decision device may send second information to the terminal, where the second information is used to instruct the terminal to initiate a test request for the second network device when sending any data to the first network device. That is, the decision device may instruct the terminal to detect the transmission quality of the second network device first, so as to send data to the UPF by using the second network device when the transmission quality of the second network device is good.

The following description will be given taking any one data as the second data.

S702, when the terminal sends the second data to the first network equipment, the terminal sends a test request for the second network equipment to the first network equipment.

And when the terminal sends the second data to the first network equipment, sending a test request for the second network equipment to the first network equipment. In one embodiment, the terminal device may send a test request for the second network device to the first network device during an idle time (e.g., an idle time slot) when the second data is sent to the first network device.

The terminal sends a test request for a second network device to a first network device, which can be understood as: the terminal sends a test request to the first network device, wherein the test request is used for requesting to test the transmission quality of the second network device.

S703, the decision device responds to the detection that the terminal initiates a test request for the second network device, closes the first network device, and starts the second network device.

In an embodiment, if the decision device is a first network device, the terminal initiates a test request for a second network device to the first network device, and the first network device may receive the test request from the terminal. In an embodiment, if the decision device is set independently of the first network device, when the first network device receives a test request from the terminal, the first network device may send the test request to the decision device, so that the decision device may detect that the terminal initiates a test request for the second network device.

The decision device may, in response to detecting that the terminal initiates a test request for the second network device, turn off the first network device and turn on the second network device to start testing the transmission quality of the second network device. In one embodiment, the decision device turning off the first network device may be: the decision device sends a shutdown instruction to the first network device, and the first network device may enter the sleep mode in response to the shutdown instruction. The manner in which the decision device initiates the second network device may refer to the relevant description in the above embodiments.

S704, the decision device sends third information to the terminal, wherein the third information is used for indicating the terminal to identify the last data packet in any data as test data and send the test data to the second network device.

The decision device may send the third information to the terminal after starting the second network device. The third information is used for instructing the terminal to identify the last data packet in any data as test data and send the test data to the second network equipment. That is, the decision device instructs the terminal to send the last data packet in the second data to the second network device as test data to test the transmission quality of the second network device.

S705, the terminal sends a data packet identified as test data to the second network device.

In one embodiment, the second data may be composed of a plurality of data packets, and the terminal sends the test request to the first network device at an idle time when sending a data packet earlier than the "last data packet" to the first network device, so that the terminal may identify the "last data packet in the second data" as the test data, and then send the data packet identified as the test data to the second network device.

S706, the decision device obtains the transmission information of the data which is identified as the test data and transmitted by the second network device.

In this embodiment, the decision device may obtain transmission information of data identified as the test data by the second network device. That is, the decision device may obtain the transmission information of the second network device based on the second network device receiving the last data packet in the second data identified as the test data. The transmission information may refer to the related description in S602 described above.

And S707, the decision device obtains the transmission quality of the second network device relative to the terminal according to the transmission information.

S706-S707 may refer to the relevant descriptions in S602-S603.

And S708, if the transmission quality of the second network equipment is greater than or equal to the first preset transmission quality, the decision-making equipment sends fourth information to the terminal, and the fourth information is used for indicating the terminal to send data to the UPF through the second network equipment.

And if the transmission quality of the second network equipment is greater than or equal to the first preset transmission quality, the decision equipment sends fourth information to the terminal. And the fourth information is used for indicating the terminal to send data to the UPF through the second network equipment.

It is conceivable that, if the transmission quality of the second network device is less than the second preset transmission quality, the decision device may start the first network device, close the second network device, and send information indicating that data is sent to the UPF through the first network device to the terminal. It should be understood that fig. 7 illustrates an example of "the transmission quality of the second network device is greater than or equal to the first preset transmission quality".

S709, the terminal sends the third data to the UPF through the second network device in response to the fourth information.

The third data is later than the second data. And after receiving the fourth information, the terminal can send third data to the UPF through the second network equipment.

It should be understood that the step of the UPF sending the third data to the server is not shown in fig. 7.

In the embodiment of the application, in response to detecting that the transmission reliability parameter value of the first network device is lower than the preset parameter value and the terminal does not support simultaneous data transmission to multiple network devices, the decision device may close the first network device and instruct the terminal to send a data packet to test the transmission quality of the second network device. If the transmission quality of the second network device is greater than or equal to the first preset transmission quality, the terminal may be instructed to send data to the UPF through the second network device. On one hand, the reliability of terminal data transmission can be ensured because the transmission quality of the second network equipment is good, and on the other hand, when the transmission reliability parameter value of the first network equipment is lower than the preset parameter value but the first network equipment fails, the decision-making equipment instructs the terminal to send data to the UPF through the second network equipment, so that uninterrupted data transmission of the terminal can be ensured, and the data transmission efficiency is improved.
