Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described in the following in conjunction with the embodiments of the present application, and it is apparent that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

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

The terminal in the embodiment of the present application may be referred to as a User Equipment (UE), for example, the terminal may be a mobile phone, a tablet computer (portable android device, PAD), a personal digital assistant (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 (augmented reality, AR) terminal device, a wireless terminal in an industrial control (industrial control), and the form of the terminal is not specifically limited in the embodiment of the present application.

The private network is different and the network equipment is different. Illustratively, in a 5G private network, the network devices may be, but are not limited to: base station, 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 node b, gNB), a new generation evolved node b (NG-eNB), a Central Unit (CU), a Distributed Unit (DU), a gNB with a separate configuration, or other nodes.

The core network elements include, but are not limited to: a user plane function (user plane function, UPF) network element, an edge computation technology (mobile edge computing, MEC) network element, a 5G core network control plane (5th generation core control plane,5GC-CP) network element, and a unified data management function (unified data management, 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, filtering messages, performing quality of service (quality of service, qoS) control related functions, etc. of a Data Network (DN) and a user plane. The MEC is used for deploying high-density computing, high-flow and low-delay service, and meets multiple requirements of users on safety, speed and reliability. The 5GC-CP is used for assisting in transmitting the user plane data. The UDM is used for managing control plane data and user plane data. The functions of the network elements in the embodiments of the present application may also refer to related descriptions in the existing 5G private network, which is not described herein.

The server may include: a server or a cluster of servers. The following examples illustrate the server side.

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 equipment, and after the network equipment receives the data, the network equipment can send the data from the terminal to the UPF. After the UPF receives the data, the UPF can send the data to the server. In one embodiment, the data sent by the terminal to the server may be referred to as uplink data, where the uplink data may be service data. In one embodiment, the upstream data may be transmitted in the form of data packets.

In order to ensure the reliability of data transmission in the private network, a plurality of network devices can be configured for the terminal to serve the terminal in the private network scene. By way of example, as shown in fig. 2, both the first network device and the second network device serve the terminal, and it should be understood that two network devices are illustrated in fig. 2 as examples. In one embodiment, the first network device or the second network device may be a primary network device, and the other network device is a backup 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.

In one embodiment, the terminal shown in fig. 2 may be one or more, and the scenario referred to in the embodiment of the present application is a scenario in which a first network device and a second network device serve a terminal set, where the terminal set includes a plurality of terminals.

Referring to fig. 2, in one embodiment, the process of transmitting data from each terminal to the server may be as follows, where a plurality of terminals are characterized by terminal 1 and terminal 2:

when transmitting data, the terminal 1 can copy the data (shown as a packet 1 in fig. 2) into two copies. The terminal 1 transmits one of the data to the first network device and another of the data to the second network device. 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. As such, the UPF needs to receive data from all network devices serving the terminal 1, e.g. the UPF may receive two identical pieces of data from the terminal 1. In one embodiment, the UPF may send the data received first to the server, or the UPF may select any one of the data to send to the server.

Similarly, the manner in which the terminal 2 transmits the data packet 2 to the server may refer to the description of "the terminal 1 transmits the data packet 1 to the server". In fig. 2, the transmission of data from terminal 1 is represented by a solid line and the transmission of data from terminal 2 is represented by a dashed line.

It should be understood that the scenario in the embodiment of the present application is: the first network device and the second network device serve a scene of the terminal set. The terminal set includes a plurality of terminals (at least two terminals). In one embodiment, the private network provides the first network device and the second network device to the plurality of terminals to serve the terminals, but in order to save the energy consumption of the network devices, only one network device serves the plurality of terminals at the same time, and when one network device fails, the other network device can be started to serve the plurality of services. For example, when the first network device serves the plurality of terminals, the second network device may be in a dormant state, and the second network device has low power consumption, as shown by a in fig. 3. And when the first network device fails, data cannot be transmitted to the plurality of terminals, the second network device may be started to transmit data to the plurality of terminals, as shown in b in fig. 3. In fig. 3, the data is still taken as an example of transmitting the data packet 1 by the terminal 1 and transmitting the data packet 2 by the terminal 2.

In the data transmission shown in fig. 3, when the first network device fails, data cannot be transmitted to a plurality of terminals, that is, in the process from the failure of the first network device to the start of the second network device, no network device transmits data to the plurality of terminals, and the data transmission of the plurality of terminals is interrupted, so that the data transmission delay of the plurality of terminals is large and the reliability is low.

The embodiment of the application provides a method for transmitting data in a private network, which can pre-start second network equipment when first network equipment does not have a fault but the performance of data transmission is reduced (or the transmission quality is poor), so that the first network equipment and the second network equipment jointly transmit data from a terminal, the data transmission of the terminal is not interrupted, and the time delay of the data transmission is further reduced.

Before the second network device is started up and data from a plurality of terminals are transmitted together by the first network device and the second network device, in order to ensure the reliability of data transmission, the transmission quality of the first network device and the second network device with respect to the terminals needs to be detected to determine the network device serving each terminal. The transmission reliability of the terminal for transmitting data through each network device is high, if the transmission quality of the network device is poor, the network device with high transmission quality can be allocated to the terminal with high priority, so that smooth transmission of the high-priority service is ensured.

It should be understood that the following embodiments take an execution body of a method for executing data transmission in a private network as an example of decision making equipment. In one embodiment, the decision device may be a first network device, a second network device, or another device that is separately configured, and in the following embodiment, the decision device is described as an example of a device that is separately configured.

The method for transmitting data in the private network provided by the embodiment of the application is described below with reference to specific embodiments. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes. Fig. 4 is a flow chart of a method for data transmission in a private network according to an embodiment of the present application. The method for data transmission in the private network provided in the embodiment of the present application is illustrated in fig. 4 in terms of a terminal, a decision device, a network device (a first network device and a second network device), and a UPF interaction.

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

s401, the decision device sends a starting instruction to the second network device.

The start instruction is used for indicating the second network equipment to switch from the dormant state to the working state. It should be appreciated that in the scenario shown in fig. 3, the first network device and the second network device in the private network serve terminals in the terminal set. And each terminal in the terminal set transmits data to the user plane function network element UPF through the first network equipment, and the second network equipment is in a dormant state.

In one embodiment, the decision device may send a start-up instruction to the second network device in response to detecting a failure of the first network device. Wherein the first network device failure can be understood as: the transmission reliability parameter value of the first network device is lower than the second preset parameter value.

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 the 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. Illustratively, the lower the 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. The transmission reliability parameter value of the first network device in the embodiment of the present application may be relative to any terminal in the terminal set, or relative to the UPF.

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

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 one embodiment, when the decision device exists independently of the first network device, the first network device may acquire its own transmission reliability parameter value and send the transmission reliability parameter value of the first network device to the decision device, so that the decision device may acquire the transmission reliability parameter value of the first network device.

The decision device stores a first preset parameter value and a second preset parameter value, and the transmission reliability parameter value of the first network device is smaller than the second preset parameter value to represent: the reliability of the transmission of the first network device is poor and insufficient to support the transmission of data, i.e. the first network device fails.

In an embodiment, in order to avoid a problem of a data transmission terminal of a terminal caused by a failure of a first network device (as shown in fig. 3), in this embodiment, in response to detecting that a transmission reliability parameter value of the first network device is smaller than a first preset parameter value but greater than a second preset parameter value, a decision device may start the second network device, so that the first network device and the second network device may serve the first terminal and the second terminal at the same time, and when the transmission reliability of the first network device is low, the decision device may be supported by the second network device, so as to improve the reliability of data transmission.

It should be appreciated that the transmission reliability parameter value of the first network device is less than the first preset parameter value but greater than the second preset parameter value characterizes: the transmission reliability of the first network device is at risk, i.e. the transmission reliability of the first network device may ensure that the first network device transmits data, but the transmission reliability is reduced. It can also be said that the first preset parameter value characterizes that the first network device has not failed, but that the probability of failure is high.

S402, after the decision device switches to the working state of the second network device, a first transmission performance test result obtained by the first network device and the second network device performing transmission performance test on each terminal in the terminal set is obtained.

After the decision device starts the second network device (e.g., the decision device sends a start instruction to the second network device), both the first network device and the second network device may serve each terminal in the terminal set. In one embodiment, after the second network device switches to the working state, information indicating that the second network device switches to the working state may be sent to the decision device, so that the decision device may determine that the second network device switches to the working state.

The first transmission performance test result includes: the transmission quality of the first network device with respect to each terminal and the transmission quality of the second network device with respect to each terminal. The transmission quality of the first network device with respect to each terminal can be regarded as a first transmission quality of each terminal, and the transmission quality of the second network device with respect to each terminal can be regarded as a second transmission quality of each terminal.

For example, the transmission quality of the first network device with respect to the first terminal may be regarded as a first transmission quality of the first terminal, and the transmission quality of the second network device with respect to the first terminal may be regarded as a second transmission quality of the first terminal.

In one embodiment, after the decision device activates the second network device, information indicating that the first network device and the second network device are used to transmit data may be transmitted to each terminal, so that each terminal may transmit data to the first network device and the second network device. For example, if the terminal set includes the first terminal and the second terminal, the first terminal may send the same data to the first network device and the second network device, and the second terminal may send the same data, which may be described with reference to fig. 2.

In this embodiment, the decision device may acquire the transmission quality of the first network device with respect to each terminal based on the transmission information that the first network device receives the data of each terminal. Similarly, the decision device may obtain the transmission quality of the second network device with respect to each terminal based on the second network device receiving the transmission information of the data of each terminal. The following describes, by taking a first network device receiving transmission information of data of a first terminal, acquiring transmission quality (abbreviated as transmission quality) of the first network device with respect to the first terminal as an example:

in one embodiment, the transmission information may include, but is not limited to, at least one of the following parameters: bit error rate, transmission rate and transmission delay. It should be appreciated that the transmission information may be reported to the decision making device for the first network device.

In one embodiment, the decision device may obtain the transmission quality based on the value of the parameter (i.e. the parameter value) included in the transmission information.

In one embodiment, the mapping relation between the values of the parameters and the transmission quality is stored in the decision device, and the decision device may obtain the transmission quality based on the values of the parameters in the transmission information and the mapping relation. For example, taking the transmission information including 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 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. For example, taking the error rate as an example, when the value of the 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 error rate is within a second preset range, the transmission quality is less than the second preset transmission quality.

It should be appreciated that the first preset transmission quality and the second preset transmission quality are preset, the first preset transmission quality being higher than the second preset transmission quality.

Table one is a mapping relationship between the values of the parameters and the transmission quality:

list one

As shown in the above table, the transmission quality is greater than or equal to the first preset transmission quality when the value of the error rate is in the range of A1-A2, the value of the transmission rate is in the range of B1-B2, and the transmission delay is in the range of C1-C2, for example.

In this way, the decision device may obtain the transmission quality of the first network device compared to each terminal and the second network device compared to the network device of each terminal.

And S403, the decision device determines the network device serving each terminal from the first network device and the second network device according to the first transmission performance test result.

In one embodiment, for a first terminal (i.e., any one of a set of terminals), a network device corresponding to a highest transmission quality of the first terminal, and the second transmission quality, may be served to the first terminal. If the first transmission quality of the first terminal is equal to the second transmission quality, or the range of the first transmission quality is equal to the range of the second transmission quality, the decision device may determine that the network device serving the first terminal is the first network device and the second network device.

And S404, the decision device sends indication information to each terminal, wherein the indication information is used for indicating the network device serving the terminal.

After the decision device determines the network device serving each terminal, the indication information may be sent to the individual terminals. The indication information is used for indicating the network equipment serving the terminal, and the indication information includes the identification of the network equipment. It should be understood that in the embodiments of the present application, each terminal in the terminal set is characterized by a terminal.

S405, the terminal sends data to the UPF through the network device serving it.

Illustratively, if the network device serving the first terminal is a first network device, the first terminal may send data to the UPF through the first network device. If the network device serving the second terminal is the first network device and the second network device, the first terminal may send data to the UPF through the first network device and the second network device, which may be referred to as related description in fig. 2.

In the embodiment of the present application, in a scenario where the first network device and the second network device serve multiple terminals, the decision device may allocate, for the terminal, a network device adapted to data transmission of the terminal to serve the terminal based on the transmission quality of the first network device with respect to each terminal and the transmission quality of the second network device with respect to each terminal, so as to improve reliability of data transmission of the terminal.

In the above embodiment, if there are a large number of terminals with the first transmission quality higher than the second transmission quality, the first network device serves a large number of terminals, and the second network device serves a small number of terminals, which may cause the load of the first network device to be too high and affect the reliability of data transmission of the terminals. In this way, in the embodiment of the present application, the decision device may allocate, for each terminal, a network device serving the terminal based on the service transmission parameter of each terminal, and the first transmission quality and the second transmission quality (i.e. the first transmission performance test result) of each terminal.

In this embodiment, referring to fig. 5, S403 may be replaced with S403A-S404A as above:

S403A, the decision device determines the transmission performance ordering of the first network device and the second network device according to the first transmission performance test result.

The first transmission performance test result includes: the transmission quality of the first network device with respect to each terminal and the transmission quality of the second network device with respect to each terminal. In one embodiment, the transmission performance of the first network device may be determined by: the average transmission quality of the first network device relative to the transmission quality of the terminal, or by the highest (or lowest) transmission quality of the first network device relative to the transmission quality of the terminal. Accordingly, the transmission performance of the second network device may be determined by: the average transmission quality of the second network device relative to the transmission quality of the terminal, or by the highest (or lowest) transmission quality of the second network device relative to the transmission quality of the terminal. In the embodiment of the present application, the transmission performance of the network device is characterized by the highest, lowest or average transmission quality relative to the transmission quality of the terminal.

The transmission performance ordering of the first network device and the second network device may be such that the transmission performance ordering of the first network device is prior and the transmission performance ordering of the second network device is subsequent.

And S404A, the decision device determines the network device serving each terminal from the first network device and the second network device according to the service transmission parameters corresponding to each terminal and the transmission performance ordering.

In this embodiment of the present application, the service transmission parameters of the terminal include at least one of the following: service transmission priority, service transmission rate, service transmission delay. The higher the traffic transmission priority, the priority transmission of the traffic should be handled. The higher the service transmission rate requirement is, the network equipment with the highest transmission performance should be allocated to the terminal. The higher the service transmission delay requirement is, the network equipment with the highest transmission performance should be allocated to the terminal.

In one embodiment, if the service transmission parameters include: the decision device may serve the terminal with network devices that are capable of satisfying the traffic transmission rate and/or the traffic transmission delay. If both network devices can meet the service transmission rate and/or service transmission delay of the terminal, the decision device may determine the network device serving each terminal from the first network device and the second network device based on the service transmission priority.

For example, the decision device may allocate, to the terminal, a network device with high transmission performance (such as the first network device) to serve the terminal according to the order of the traffic transmission priority of the terminal from high to low, until the load of the first network device is greater than or equal to the preset load threshold, and stop allocating the terminal to the first network device. The decision device may assign the remaining terminals to the second network device for serving it.

The manner for measuring that the load of the first network device is greater than or equal to the preset load threshold may be: the number of the terminals served by the first network device reaches a preset number, or the ratio of the number of the terminals served by the first network device in the total number of the terminals reaches a preset ratio, or the traffic of the terminals served by the first network device reaches a preset traffic.

In the embodiment of the application, the decision device can allocate the network device serving for each terminal based on the service transmission parameter of each terminal and the transmission performance of each network device, so that the requirement of the terminal on data transmission can be ensured, and the reliability of terminal data transmission with high service transmission priority can be ensured.

In the above embodiment, the decision device receives the transmission information of the data from each terminal by using the first network device, obtains the transmission quality of the first network device relative to each terminal, and receives the transmission information of the data from each terminal by using the second network device, and obtains the transmission quality of the second network device relative to each terminal.

Therefore, in the embodiment of the present application, the terminals in the terminal set may be divided into a plurality of groups, so that the first network device and the second network device respectively serve different terminal groups, so as to reduce the load of the network device, and ensure smooth acquisition of the first transmission performance test result. In one embodiment, in order to reduce the duration of acquiring the first transmission performance test result, the terminal set may be divided into a first terminal group and a second terminal group for testing.

In this embodiment, referring to fig. 6, S402 may be replaced with S402B-S403B, and it should be understood that fig. 6 is shown on the basis of fig. 5, and in one embodiment, S402 may be replaced with S402B-S403B on the basis of fig. 4 as well).

The first network device divides the terminal set into a first terminal group and a second terminal group S402B.

In one embodiment, when the decision device is a first network device, the decision device may divide the terminal set into a first terminal group and a second terminal group in response to the second network device switching to an operational state.

In one embodiment, when the decision device is not the first network device, the decision device may send information to the first network device indicating that the first network device divides the terminal group in response to the second network device switching to an operational state. The first network device may divide the terminal set into a first terminal group and a second terminal group in response to the information.

The first network device may divide the terminals in the terminal set into two parts, i.e. into a first terminal group and a second terminal group.

In one embodiment, the first network device divides the set of terminals into a first terminal group and a second terminal group according to the attribute of each terminal. Wherein the attribute of the terminal comprises at least one of the following: location, transmitted signal strength, and traffic type. It will be appreciated that each terminal may report the attributes of the terminal to the network device serving it, and thus the first network device may obtain the attributes of each terminal.

For example, the first network device may divide terminals whose locations are within a preset distance range of the first network device into one group and terminals at other locations into another group. Alternatively, the first network device may divide terminals whose transmitted signal strength is greater than a preset strength into one group and divide the remaining terminals into another group. The embodiment of the application does not limit the mode of dividing the terminal group by the first network equipment.

S403B, the decision device controls the first network device and the second network device to respectively test transmission performance of the terminals in the first terminal group and the second terminal group, and a first transmission performance test result is obtained.

After the first network device divides the terminal set into the first terminal group and the second terminal group, the information of the first terminal group and the information of the second terminal group may be sent to the second network device. For example, the information of the first terminal group may include an identifier of each terminal in the first terminal group, and the identifier of the terminal may be an attribute of the terminal. The information of the second terminal group may include an identification of each terminal in the second terminal group. In this way, the second network device may determine the terminals included in the first terminal group and the terminals included in the second terminal group.

Because the terminal set is divided into two terminal groups, the transmission quality of the first network device and the second network device) with respect to each terminal is completely acquired, two test periods are required for the test, i.e., a first test period and a second test period. The first test period and the second test period are predetermined, for example, in the first test period, the first network device serves the first terminal group, and the second network device serves the second terminal group. In a second test period, the first network device serves the second terminal group, and the second network device serves the first terminal group.

In one embodiment, before the first test period, the first network device may send first information to each terminal in the first terminal group, the first information indicating that the terminal uses the first network device to send data to the UPF, and the second network device may send second information to each terminal in the second terminal group, the second information indicating that the terminal uses the second network device to send data to the UPF. And when the first test period is finished, the first network equipment can send third information to each terminal in the second terminal group, the third information indicates the terminal to send data to the UPF by adopting the first network equipment, the second network equipment can send fourth information to each terminal in the first terminal group, and the fourth information indicates the terminal to send data to the UPF by adopting the second network equipment.

In this way, in the first test period, the first network device provides a transmission service for the terminals of the first terminal group to obtain the transmission quality of each terminal, and the transmission quality of each terminal can be understood as the first transmission quality of each terminal in the first test period, that is, the transmission quality of the first network device relative to each terminal in the first terminal group. In the first test period, the decision device may acquire the transmission quality of the first network device with respect to the terminal based on the transmission information of each terminal, and reference may be made to the description related to the transmission quality of the first network device with respect to the first terminal in S402.

Similarly, in the second test period, the first network device provides a transmission service for the terminals of the second terminal group to obtain the transmission quality of each terminal, that is, the transmission quality of the first network device relative to each terminal in the second terminal group.

Similar to the first network device, in the first test period, the second network device provides a transmission service for the terminals of the first terminal group to obtain a transmission quality of each terminal, i.e. the transmission quality of the second network device with respect to each terminal in the first terminal group. In the second test period, the second network device provides transmission service for the terminals of the second terminal group to obtain the transmission quality of each terminal, namely the transmission quality of the second network device relative to each terminal in the second terminal group.

In this way, the decision device may obtain the transmission quality of the first network device with respect to each terminal in the set of terminals, and the transmission quality of the second network device with respect to each terminal in the set of terminals.

In one embodiment, S402B-S403B may be replaced with: the decision device obtains a transmission quality of the first network device with respect to each terminal of the first terminal group and the second terminal group, and obtains a transmission quality of the second network device with respect to each terminal of the first terminal group and the second terminal group.

In the embodiment of the present application, the terminals in the terminal set may be divided into a first terminal group and a second terminal group, so that on one hand, the first network device and the second network device may service different terminal groups respectively, so as to reduce the load of the network device, ensure smooth acquisition of the first transmission performance test result, and on the other hand, also reduce the duration of acquiring the first transmission performance test result, i.e. quickly obtain the first transmission performance test result.

As taught in the above examples are: after starting the second network device, how to allocate the network device serving it to the terminal. The embodiment of the application also provides a transmission method, which can ensure the reliability of data transmission of the terminal after the terminal is distributed to the network equipment serving the terminal, that is, in the embodiment of the application, the network equipment serving the terminal can be dynamically adjusted in real time, and the reliability of data transmission of the terminal is improved.

The above embodiments teach that each terminal can report the location of the terminal to the network device that serves it. In this way, the first network device or the second network device may report the location of the terminal to the decision device, so that the decision device may obtain the location of each terminal, and the total number of terminals. The change in the location of the terminal results in a change in the transmission quality of the terminal (e.g., the transmission quality of the first network device relative to the terminal and the transmission quality of the second network device relative to the terminal). Therefore, in the embodiment of the present application, the network device serving the terminal may be adjusted based on the location of the terminal in real time. The location may be referred to as location information, which may characterize the coordinates of the terminal, such as longitude and latitude.

In this embodiment, referring to fig. 7, after S404 as above, it may further include:

s701, the decision device monitors whether the position of each terminal changes.

The change in the position of the terminal can be understood as: the distance between the original position and the current position of the terminal is larger than the preset distance. It will be appreciated that since the decision device can acquire the location of each terminal from the network device serving each terminal in real time, the decision device can monitor whether the location of each terminal has changed.

S702, if the number of the terminals with the changed positions is greater than a preset threshold, the decision device obtains a second transmission performance test result obtained by the first network device and the second network device executing the transmission performance test on the terminals with the changed positions.

If the decision device detects that the number of the terminals with the changed positions is greater than a preset threshold, the decision device indicates that the transmission quality of a plurality of terminals is possibly changed, and if the former network device is adopted to serve the terminals, the transmission reliability is reduced, so in the embodiment of the application, the decision device can acquire a second transmission performance test result obtained by performing the transmission performance test on the position-changing terminals by the first network device and the second network device. In one embodiment, the preset threshold may be half of the total number of terminals, which is not limited in the embodiments of the present application.

That is, when the number of terminals whose positions are changed is greater than a preset threshold, the first network device and the second network device need to retest to acquire transmission quality with respect to "terminals whose positions are changed". In such an embodiment, the first network device may divide the "location-changed terminal" into the third terminal group and the fourth terminal group to obtain the transmission quality of the first network device with respect to each of the third terminal group and the fourth terminal group, and obtain the transmission quality of the second network device with respect to each of the third terminal group and the fourth terminal group, and reference may be made to the related descriptions of the "first terminal group and the second terminal group".

It should be understood that the second transmission performance test result may include: the transmission quality of the first network device with respect to each of the "terminals with change in location", and the transmission quality of the second network device with respect to each of the "terminals with change in location".

S703, the decision device determines the network device serving each terminal from the first network device and the second network device according to the second transmission performance test result and the transmission quality of the terminal with unchanged position in the first transmission performance test result.

The second transmission performance test result includes a new first transmission quality and a new second transmission quality of each terminal in the 'position-changed terminal', and the first transmission performance test result includes: the transmission quality of the terminal whose position is unchanged (i.e., the first transmission quality and the second transmission quality of each terminal in the "terminal whose position is unchanged").

The decision device may determine a transmission performance ranking of the first network device and the second network device according to the second transmission performance test result and the transmission quality of the terminal with no position change in the first transmission performance test result, and further determine a network device serving each terminal from the first network device and the second network device according to the service transmission parameters of each terminal and the transmission performance ranking of the first network device and the second network device.

Wherein determining the transmission performance ordering of the first network device and the second network device may refer to the relevant description in S403A. "the network device serving each terminal is determined from the first network device and the second network device according to the traffic transmission parameters of the terminals and the transmission performance ranks of the first network device and the second network device" may refer to the relevant description in S404A. Except that, unlike S403A to S404A described above, for the terminals whose positions are changed, a new first transmission quality and a new second transmission quality of each terminal are employed.

And S704, if the number of the terminals with the changed positions is smaller than or equal to a preset threshold, determining whether to adjust the network equipment of the terminal with the changed positions according to the service transmission parameters of the terminal with the changed positions by the decision device.

If the decision device detects that the number of the terminals with the changed positions is smaller than or equal to a preset threshold, the decision device indicates that the transmission quality of only a few terminals is changed, and the reliability of data transmission of most terminals is high, so that network devices are not allocated to all the terminals again. Therefore, in the embodiment of the present application, the decision device may determine whether to adjust the network device of the terminal whose service location changes according to the service transmission parameter of the terminal whose location changes.

For example, among the terminals with changed positions, there is a terminal with high service priority, and the change of the position of the terminal affects the reliability of data transmission to a great extent, so that the network device needs to be adjusted to the terminal with high service priority in time to ensure smooth transmission of the data with high service priority.

Therefore, in the embodiment of the present application, the decision device may determine, according to the service transmission parameters of the terminal whose position changes, whether the target terminal of the network device to be adjusted exists in the terminal whose position changes. It should be understood that the target terminal may be a terminal with a service priority higher than a preset priority, and/or a terminal with a transmission rate requirement higher than a preset rate, and/or a terminal with a transmission delay requirement less than a preset delay.

If the terminal with the changed position does not have the target terminal of the network device to be adjusted, the decision device may not adjust the network device serving each terminal.

And S705, if the target terminal of the network equipment to be adjusted exists, the decision device acquires a third transmission performance test result obtained by the first network equipment and the second network equipment executing the transmission performance test on the target terminal.

If the terminal with the changed position has the target terminal of the network equipment to be adjusted, the decision device needs to reassign the network equipment to the target terminal.

Specifically, the decision device may re-obtain a third transmission performance test result obtained by performing the transmission performance test on the target terminal by the first network device and the second network device.

In one embodiment, because the number of target terminals is small, the decision device may obtain the transmission quality of the first network device with respect to the target terminal and the transmission quality of the second network device with respect to the terminal based on the transmission information that the first network device and the second network device receive the data from the target terminal, which may be described with reference to the correlation in S402.

Alternatively, in an embodiment, the first network device may divide the target terminal into a fifth terminal group and a sixth terminal group, so as to obtain transmission quality of the first network device with respect to each terminal in the fifth terminal group and the sixth terminal group, and obtain transmission quality of the second network device with respect to each terminal in the fifth terminal group and the sixth terminal group, which may be referred to as a related description of "the first terminal group and the second terminal group".

S706, the decision device determines the network device serving the target terminal from the first network device and the second network device according to the third transmission performance test result and the transmission quality of the target terminal in the first transmission performance test result.

The third transmission performance test result includes: the new transmission quality of the first network device with respect to the target terminal, i.e. the new first transmission quality of the target terminal, and the new transmission quality of the second network device with respect to the target terminal, i.e. the new second transmission quality of the target terminal.

In the embodiment of the present application, the decision device may determine, according to the third transmission performance test result and the transmission quality of the target terminal in the first transmission performance test result, a network device serving the target terminal from the first network device and the second network device. That is, the decision device may allocate the network device to the target terminal according to the new first transmission quality, the new second transmission quality, and the original first transmission quality and the original second transmission quality of the target terminal (i.e. as tested by the first test period and the second test period above).

The decision device may determine whether the transmission quality of the target terminal changes according to the third transmission performance test result and the transmission quality of the target terminal in the first transmission performance test result. Such as whether the new first transmission quality and the original first transmission quality of the target terminal change, and whether the new second transmission quality and the original second transmission quality change.

If the transmission quality of the target terminal changes (e.g., the first transmission quality and/or the second transmission quality changes), determining an initial network device serving the target terminal from the first network device and the second network device. The decision device may determine a transmission performance ranking of the first network device and the second network device with respect to the target terminal according to the third transmission performance test result, and further determine an initial network device serving the target terminal from the first network device and the second network device according to the service transmission parameters of the target terminal and the transmission performance ranking of the first network device and the second network device, which may refer to the relevant descriptions of S403A-S404A.

The initial network device serving the target terminal is said to be the initial network device because in the embodiment of the present application, it is further required to determine whether to let the initial network device serve the target terminal based on the load of the initial network device. If the load of the initial network device after serving the target terminal is less than or equal to the preset load threshold, the load indicates that the transmission performance of the initial network device is not reduced after the initial network device serves the target terminal, and the reliability of data transmission of the terminal can be ensured, so that the decision device can take the initial network device as the network device of the serving target terminal.

If the load of the initial network device after serving the target terminal is greater than the preset load threshold, it indicates that the transmission performance of the initial network device is reduced after the initial network device serves the target terminal, and the reliability of data transmission of the terminal cannot be guaranteed, so that the decision device needs to reallocate the network device for each terminal based on the transmission quality of each terminal again.

In this embodiment, the decision device may obtain a fourth transmission performance test result obtained by performing the transmission performance test on the remaining position change terminals (terminals other than the target terminal in all the position changes) by the first network device and the second network device, and the transmission performance test may refer to a description related to the transmission performance test of the target terminal.

The fourth transmission performance test result includes: the remaining position changes the new first transmission quality and the new second transmission quality of the terminal. The decision device may determine a network device serving each terminal from the first network device and the second network device according to the fourth transmission performance test result, the third transmission performance test result, and the transmission quality of the terminal whose position is unchanged in the first transmission performance test result.

That is, the decision device may determine the transmission performance ranking of the first network device and the second network device with respect to each terminal based on the "new first transmission quality and new second transmission quality of the remaining location change terminal", "new first transmission quality and new second transmission quality of the target terminal", and "first transmission quality and second transmission quality of the location unchanged terminal", and further determine the initial network device serving each terminal from the first network device and the second network device according to the traffic transmission parameters of each terminal and the transmission performance ranking of the first network device and the second network device, and may refer to the related descriptions of S403A-S404A.

In the embodiment of the application, after the second network device is started, the decision device distributes the network device serving the terminal to the decision device, and then the decision device can dynamically adjust the network device serving the terminal in real time, so that the reliability of data transmission of the subsequent terminal is improved.
