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 uplink data may be sent in the form of a data packet, and in the following embodiment, the data sent by the terminal to the server may also be sent in the form of a data packet.
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. Illustratively, as shown in fig. 2, the first network device and the second network device serve a plurality of terminals, it being understood that in fig. 2 two network devices are illustrated and the plurality of terminals are illustrated as a first terminal and a second terminal. 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.
Referring to fig. 2, in one embodiment, for example, the first terminal may be terminal 1, the second terminal may be terminal 2, and the process of transmitting data from each terminal to the service end may be as follows, where the following characterizes a plurality of terminals with 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.
In this scenario, the embodiment of the application provides a method for transmitting data in a private network, when there is a probability of failure of a first network device serving a plurality of terminals, that is, when the first network device fails, but the performance of transmitting data is reduced (or the transmission quality is poor), a second network device is started in advance, so that the first network device and the second network device jointly transmit the data from the terminals, so that the data transmission of the terminals is not interrupted, and further, the delay of the data transmission is reduced.
Unlike the scenario where the first network device and the second network device serve one terminal, because of the large number of terminals, if the processing is performed according to the processing mode of one terminal, there is a delay in data of each terminal. Therefore, in the embodiment of the present application, aiming at the scenario that the first network device and the second network device serve multiple terminals at the same time, attention is paid to how to improve the reliability of data transmission of the multiple terminals and reduce the delay of data transmission.
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. In fig. 4, a method for transmitting data in a private network provided in an embodiment of the present application is illustrated in terms of a terminal (a first terminal and a second terminal), a decision device, a network device (a first network device and a second network device), and a UPF interaction. It should be understood that the first terminal and the second terminal are illustrated in fig. 4 as representative of a plurality of terminals.
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 first terminal sends first data to the first network device.
It should be understood that in the embodiment of the present application, the first terminal may send the first data to the server through the first network device and the UPF in sequence, and the second network device is in a dormant state. In one embodiment, the first data may be a data packet.
S402, the first network device sends first data to the server through UPF.
S401-S402 represent that the first terminal transmits data to the server through a network device serving it. In one embodiment, the first network device may be a master network device. It should be understood that the server is not shown in fig. 4.
S403, the second terminal sends second data to the first network device.
S404, the first network device sends second data to the server through UPF.
S403-S404 represent that the second terminal transmits data to the server through a network device serving it. S403 to S404 are not sequentially distinguished from S401 to S402, and may be performed simultaneously.
And S405, the decision device starts the second network device in response to detecting that the transmission reliability parameter value of the first network device is lower than the preset parameter value.
It should be understood that S405 is not sequentially distinguished from S401-S402 and S403-S404, and in this embodiment of the present application, the decision device detects that the transmission reliability parameter value of the first network device is lower than the preset parameter value after S401-S402 and S403-S404.
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.
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 preset parameter value, and the transmission reliability parameter value of the first network device is smaller than the preset parameter value to represent: 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 preset parameter value characterizes that the first network device has not failed, but that the probability of failure is high.
The decision device may start the second network device in response to detecting that the transmission reliability parameter value of the first network device is lower than the preset parameter value, 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 second network device may support the first network device, so as to improve the reliability of data transmission.
In one embodiment, the decision device to start the second network device may be understood as: the decision device sends a start instruction to the second network device. 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 so as to serve the terminal. It should be understood that fig. 4 illustrates an example in which the decision device sends a start instruction to the second network device.
And S406, the decision device sends the first information to each terminal in the terminal set.
The first information is used for indicating 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 inform 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 the data of the terminal may be transmitted with reference to the method shown in fig. 2.
In this embodiment of the present application, in response to detecting that the transmission reliability parameter value of the first network device is lower than a preset parameter value, the decision device does not detect whether each terminal in the terminal set supports simultaneous data transmission to a plurality of network devices, but directly starts the second network device to send the first information to each terminal in the terminal set, because: when the number of terminals is large, the decision device detects whether each terminal supports transmitting data to a plurality of network devices at the same time, which takes a long time.
In this embodiment, after the terminal receives the first information, if the terminal supports transmitting data to the plurality of network devices at the same time, the same data may be transmitted to the first network device and the second network device, and if the terminal does not support transmitting data to the plurality of network devices at the same time, the data may be transmitted in an original manner (through the first network device), because the first network device has not failed at this time, so that the data transmission of the terminal may be ensured.
It should be appreciated that S406 is characterized in fig. 4 by S406A and S406B:
and S406A, the decision device sends first information to the first terminal.
And S406B, the decision device sends the first information to the second terminal.
S406A and S406B are not sequentially distinguished, and may be performed simultaneously.
S407A, the first terminal transmits the third data to the first network device and transmits the third data to the second network device.
S407B, the second terminal transmits fourth data to the first network device, and transmits fourth data to the second network device.
S407A and 407B are not sequentially distinguished, and may be performed simultaneously.
In one embodiment, in order to further ensure reliability of data transmission, before the first terminal and the second terminal use the second network device to transmit data, the transmission quality of the second network device may be tested first, and when the transmission quality of the second network device is relatively high (e.g., greater than a preset quality), the terminal uses the first network device and the second network device to send the same data to the UPF at the same time.
In the embodiment of the application, in order to save the test time of the transmission quality of the second network device and further reduce the data transmission delay, the transmission quality of the second network device relative to the first terminal can be directly obtained based on the transmission information of the third data received by the second network device, and the transmission quality of the second network device relative to the second terminal can be obtained based on the transmission information of the fourth data received by the second network device, so that the normal transmission of the data from the terminal can be ensured, and the transmission quality of the second network device relative to the terminal can be detected.
In one embodiment, the transmission information may include at least one of: bit error rate, transmission rate and transmission delay.
In the following, the decision device may acquire, according to the transmission information, a transmission quality of the second network device with respect to the first terminal (simply referred to as a transmission quality in the following embodiment) as an example. It should be understood that the transmission quality of the second network device with respect to the first terminal refers to: transmission quality when the second network device transmits data from the first terminal. 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
Figure BDA0003377436020000131
As shown in the above table, the transmission quality of the second network device with respect to the first terminal 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, by way of example.
As such, in the embodiment of the present application, after S407A and S407B may include:
and S408A, the decision device determines a target mode of the first terminal for sending data to the UPF according to the transmission reliability parameter value of the first network device and the transmission quality of the second network device relative to the first terminal.
The transmission reliability parameter value of the first network device characterizes the transmission reliability of the first network device, and the transmission reliability of the first network device characterizes: the reliability of the first network device for transmitting the data from the first terminal is higher, so that the smooth transmission of the data from the first terminal can be ensured. Transmission quality characterization of the second network device with respect to the first terminal: the higher the transmission quality of the second network device with respect to the first terminal, the more reliable the second network device can transmit data from the first terminal.
In one embodiment, the target means includes any one of the following: the first transmission mode, the second transmission mode, the third transmission mode and the fourth transmission mode. The first transmission mode is as follows: the first terminal sends data to the UPF through the first network equipment, and the second transmission mode is as follows: the first terminal sends data to the UPF through the second network equipment, and the third transmission mode is as follows: the first terminal sends the same data to the UPF through the first network device and the second network device, and the fourth transmission mode is as follows: the first terminal selects a target network device from the first network device and the second network device, and sends data to the UPF through the target network device.
It is noted that the fourth transmission mode is a target network device that the first terminal decides itself to send data to the UPF. In one embodiment, the target network device is a primary network device, such as a first network device. Or the target network device is a second network device, or the first network device and the second network device. In one embodiment, the target network device is pre-configured. In other words, when the target mode is the fourth transmission mode, the terminal transmits data to the UPF according to the agreed network device (i.e., the target network device).
In one embodiment, the decision device stores therein a mapping relationship of a transmission reliability parameter value, a transmission quality of the second network device relative to the first terminal, and a target manner in which the first terminal sends data to the UPF. For example, taking the transmission reliability parameter value as an error rate as an example, the error rate is in a first error rate range, and the transmission quality of the second network device relative to the first terminal is in a first transmission quality range, then the target mode of the first terminal for sending data to the UPF may be the first transmission mode.
For example, the mapping relationship of "transmission reliability parameter value, transmission quality of the second network device with respect to the first terminal, and destination manner of the first terminal sending data to the UPF" may refer to table two:
watch II
Figure BDA0003377436020000141
It should be understood that a1-a2, b1-b2, c1-c2, and the first, second, and third transmission quality ranges in table two are schematic illustrations, and that actual table two carries specific values.
In one embodiment, the decision device may obtain a level of transmission reliability of the first network device according to the transmission reliability parameter value, and further determine a target manner in which the first terminal sends data to the UPF according to the level of transmission reliability of the first network device and a transmission quality of the second network device relative to the first terminal. The higher the transmission reliability level, the higher the transmission reliability is, namely, the more smooth transmission of the data from the terminal can be ensured.
In one embodiment, the transmission reliability level may be divided into a first level and a second level, the first level being higher than the second level. And when the transmission reliability is of the second level, the risk of the transmission reliability of the first network equipment is high. In addition, the decision device may store the first preset quality and the second preset quality in advance, so as to divide the transmission quality into three levels, such as a level greater than or equal to the first preset quality, a level less than the second preset quality, and a level less than the first preset quality and greater than or equal to the second preset quality. Wherein the first preset quality is greater than (or higher than) the second preset transmission quality.
In an embodiment, the decision device may also detect a moment in time when the first network device receives the third data from the first terminal, like T1. If the decision device detects that the second network device does not receive the third data from the first terminal within the preset verification time window after T1, the decision device may determine that the transmission quality of the second network device with respect to the first terminal is smaller than the second preset transmission quality.
When the decision device is set independently of the first network device and the second network device, the first network device can send a message for completing the reception of the third data to the decision device in response to receiving the second data from the first terminal, and similarly, the second network device can send a message for completing the reception of the third data to the decision device in response to receiving the third data from the first terminal. In this way, the decision device may take the time when the message is received as the time T1 when the first network device receives the third data from the first terminal, and in a preset verification time window after T1, if the decision device does not receive the message from the second network device that completes receiving the third data, it may be determined that the second network device does not receive the third data in the preset verification time window after T1. If the decision device receives a message from the second network device that the third data is received within the preset verification time window after T1, it may be determined that the second network device receives the third data within the preset verification time window after T1.
When the decision device is the first network device, the second network device may send a message to the first network device that the third data is received in response to receiving the third data from the first terminal. The first network device may record the received time T1 in response to receiving the third data from the first terminal, and if the first network device does not receive the message from the second network device for completing receiving the third data within a preset verification time window after T1, it may be determined that the second network device does not receive the third data within the preset verification time window after T1. If the first network device receives a message from the second network device that the third data is received within the preset verification time window after T1, it may be determined that the second network device does not receive the third data within the preset verification time window after T1.
The scenario in which the decision device is the second network device may be referred to the description related to the above "when the decision device is the first network device".
Based on the above-mentioned classification of the level of transmission reliability and the classification of the transmission quality, the following teaches that the decision device determines the manner in which the first terminal transmits data to the UPF:
first, if the level of the transmission reliability is a first level and the second network device is smaller than a second preset transmission quality with respect to the first terminal, the decision device determines that the target mode is the first transmission mode.
And secondly, if the transmission reliability grade is the first grade and the second network equipment is larger than or equal to the first preset transmission quality relative to the first terminal, the decision device determines that the target mode is the third transmission mode.
Thirdly, if the transmission reliability level is a second level and the second network device is greater than or equal to a second preset transmission quality with respect to the first terminal, the decision device determines that the target mode is a second transmission mode.
Fourth, if the transmission reliability is at the second level and the second network device is smaller than the second preset transmission quality with respect to the first terminal, the decision device determines that the target mode is the fourth transmission mode. In the following embodiments, fig. 4 illustrates an example in which a first target manner is a target manner in which a first terminal transmits data to a UPF, and a second target manner is a target manner in which a second terminal transmits data to the UPF. The first target means and the second target means may be the same or different.
And S408B, the decision device determines a target mode of sending data to the UPF by the second terminal according to the transmission reliability parameter value of the first network device and the transmission quality of the second network device relative to the second terminal.
S408B may refer to the related description of S408A.
And S409A, the decision device sends second information to the first terminal, wherein the second information instructs the first terminal to send data to the UPF in a first target mode.
The first target manner is a third transmission manner, and the first terminal may send the same data to the UPF through the first network device and the second network device.
It should be understood that after the first terminal receives the second information, the data may be sent to the UPF in a target manner corresponding to the first terminal, which is not shown in fig. 4.
And S409B, the decision device sends second information to the second terminal, wherein the second information instructs the second terminal to send data to the UPF in a second target mode.
The second target mode is a first transmission mode, and the second terminal may send data to the UPF through the first network device. It should be understood that after the second terminal receives the second information, the second terminal may send data to the UPF in a target manner corresponding to the second terminal, which is not shown in fig. 4.
In one embodiment, referring to fig. 5, when the decision device sends the second information to the first terminal, the decision device may further output first alarm information, where the first alarm information is used to indicate that the transmission quality of the second network device is poor, and the second network device is not available. Illustratively, fig. 5 illustrates that the decision device sends the first alert information to the first terminal (S410A), and the decision device sends the second alert information to the second terminal (S410B).
In one embodiment, the manner in which the decision device outputs the first alert information may include, but is not limited to,: the decision device displays text prompt information of 'poor transmission quality of the second network device or unavailable' of the second network device, or the decision device plays voice of 'poor transmission quality of the second network device or unavailable' of the second network device, so as to prompt a manager of the network device in time.
In one embodiment, when the decision device sends the second information to the terminal, the decision device may further output second alarm information, where the second alarm information is used to indicate that the transmission reliability of the first network device is low, and the first network device is not available.
In an embodiment, when the decision device sends the second information to the terminal, a third alarm information may be further output, where the third alarm information is used to indicate that the transmission reliability of the first network device is low, and the transmission quality of the second network device is poor, for example, the transmission reliability of the first network device is rated as a second level, and the transmission quality of the second network device relative to the first terminal is smaller than a second preset transmission quality.
The mode of outputting the second alarm information and the third alarm information by the decision device can refer to the related description of the first alarm information.
In the embodiment of the present application, when the first network device is not in failure, but when the first network device has a risk of reliable transmission, that is, the first network device is not in failure, but when the performance of transmitting data is reduced, the second network device is started in advance, so that the data transmission of the terminal is not interrupted, and further, the time delay of the data transmission is reduced. In addition, for the scene that the first network device and the second network device serve a plurality of terminals, the decision device can determine the transmission mode suitable for each terminal based on the transmission reliability parameter value of the first network device and the transmission quality of the second network device relative to each terminal, so that the terminal can adopt the corresponding transmission mode to transmit data, each terminal is considered, the reliability of data transmission can be ensured,
in the above embodiment, an example is described in which the decision device may send the first information to each terminal in the terminal set at the same time, and sending the first information to the plurality of terminals at the same time occupies many resources of the decision device, which results in high resource occupancy rate of the decision device.
For example, for a terminal with a higher service priority, the decision device may send the first information to the terminal preferentially, and after each terminal receives the first information, the steps in the above embodiments may be performed. Furthermore, the terminal with higher service priority can process and transmit own data preferentially, and under the condition of poor transmission quality of the network equipment, the embodiment of the application can ensure the priority transmission of the data with the service priority and ensure the success of important service.
In such an embodiment, referring to fig. 5, S406A and S406B described above may be replaced with S406C: the decision device may send the first information to each terminal in turn according to the order of the service priorities of the terminals in the terminal set from high to low.
