Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the embodiments of the present application, and it is obvious that the described embodiments are some but not all of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The private network in the embodiment of the present application may include, but is not limited to: a fifth generation mobile communication technology (5th generation mobile communication technology, 5G) private network, a 4G private network, and the like. The following description will be given by taking a 5G private network as an example. Fig. 1 is a schematic view of a scenario in which the method for data transmission in a private network according to the embodiment of the present application is applied. Referring to fig. 1, the private network scenario may include: the system comprises a terminal, network equipment, a core network element and a server. It should be understood that the private network scenario illustrated in fig. 1 does not constitute a specific limitation to the private network scenario. In other embodiments of the present application, a private network scenario may include more or fewer devices than shown, or some devices may be combined, some devices may be split, or a different arrangement of devices.
The terminal in this embodiment may be referred to as a User Equipment (UE), for example, the terminal may be a mobile phone, a tablet computer (PAD), a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device, a wearable device, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), and the like, and a form of the terminal is not particularly limited in this embodiment.
Private networks are different and network devices are different. For example, in a 5G private network, the network devices may be, but are not limited to: a base station, a next generation base station (which may be collectively referred to as a new generation radio access network node (NG-RAN node)). The next generation base station may include a new air interface base station (NR nodeB, gNB), a new generation evolved base station (NG-eNB), a Central Unit (CU), a Distributed Unit (DU), a gNB in a separate form), or other nodes.
Core network elements include, but are not limited to: a User Plane Function (UPF) network element, an edge computing technology (MEC) network element, a 5G core control plane (5 GC-CP) network element, and a unified data management function (UDM) network element. In an embodiment, the core network element may further include more or fewer network elements, which is not limited in this embodiment of the present application.
The UPF is mainly responsible for routing and forwarding data packets externally connected to a Data Network (DN) and a user plane, filtering packets, and performing quality of service (QoS) control related functions. The MEC is used for deploying services with high-density calculation, large flow and low time delay requirements, and meets multiple requirements of users on safety, speed and reliability. The 5GC-CP is used to assist in the transmission of user plane data. The UDM is used to manage control plane data and user plane data. The functions of the network elements involved in the embodiment of the present application may also refer to related descriptions in the existing 5G private network, which are not described herein again.
The server side can comprise: a server or a cluster of servers. In the following embodiments, a server is taken as an example for explanation.
The following describes a data transmission process from a terminal to a server in a private network scenario with reference to the private network scenario shown in fig. 1. When the terminal transmits data to the server, the terminal can send the data to the network device, and after receiving the data, the network device can send the data from the terminal to the UPF. After receiving the data, the UPF may send the data to the server. In an embodiment, data sent by the terminal to the server may be referred to as uplink data, and the uplink data may be service data. In an embodiment, the uplink data may be sent in the form of a data packet, and in the following embodiments, 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, in the private network scenario, a plurality of network devices may be configured for the terminal to serve. Illustratively, as shown in fig. 2, the first network device and the second network device serve a plurality of terminals, and it should be understood that fig. 2 illustrates two network devices, and the plurality of terminals take the first terminal and the second terminal as an example. In one embodiment, the first network device or the second network device may be a master network device and the other network device is a standby network device. It should be understood that the devices in the private network involved in the embodiments of the present application are shown in fig. 2, and the MEC, 5GC-CP, and UDM are not shown.
Referring to fig. 2, in an embodiment, if the first terminal may be terminal 1 and the second terminal may be terminal 2, a process of each terminal transmitting data to the server may be as follows, where a plurality of terminals are characterized by terminal 1 and terminal 2 as follows:
when transmitting data, the terminal 1 can copy the data (indicated by packet 1 in fig. 2) into two copies. The terminal 1 sends one of the data to the first network device and sends the other 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. Thus, the UPF needs to receive data from all network devices serving terminal 1, e.g. the UPF can receive two identical copies of data from terminal 1. In one embodiment, the UPF may send the data received first to the server, or the UPF may select any of the data to send to the server.
Similarly, the manner in which the terminal 2 sends the data packet 2 to the server may refer to the description of "the terminal 1 sends the data packet 1 to the server". Fig. 2 is a solid line representing transmission of data from terminal 1 and a dashed line representing transmission of data from terminal 2.
It should be understood that the scenarios in the embodiment of the present application are: the first network device and the second network device serve a scenario of a terminal set. The terminal set includes a plurality of terminals (at least two terminals). In one embodiment, although the private network provides the first network device and the second network device for the plurality of terminals to serve the terminals, in order to save 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, another network device can be started to serve the plurality of terminals. For example, when the first network device serves the plurality of terminals, the second network device may be in a sleep state, and the second network device consumes low power, as shown in a in fig. 3. And when the first network device fails and cannot transmit data for the plurality of terminals, the second network device may be started to transmit data for the plurality of terminals, as shown in b in fig. 3. Fig. 3 also illustrates an example in which data is transmitted as a data packet 1 by the terminal 1, and a data packet 2 is transmitted by the terminal 2.
In the data transmission shown in fig. 3, when the first network device fails, data cannot be transmitted for the multiple terminals, that is, in a process from the failure of the first network device to the start of the second network device, no network device transmits data for the multiple terminals, and data transmission of the multiple terminals is interrupted, which results in a large data transmission delay and low reliability of the multiple terminals.
In this scenario, an embodiment of the present application provides a method for data transmission in a private network, where when a first network device serving multiple terminals has a probability of failure, that is, the first network device does not have a failure, but performance of transmitting data is reduced (or transmission quality is poor), a second network device is started in advance, so that the first network device and the second network device transmit data from the terminals together, so that data transmission of the terminals is uninterrupted, and further, delay of data transmission is reduced.
Different from a scenario in which the first network device and the second network device serve one terminal, because the number of terminals is large, if the terminals are processed according to a processing mode of one terminal, data of each terminal may also have a time delay. Therefore, in the embodiment of the present application, in order to "a scenario in which the first network device and the second network device serve multiple terminals at the same time", how to improve the reliability of data transmission of the multiple terminals and reduce the delay of data transmission is focused.
It should be understood that the following embodiments are described by taking the implementation subject of the method for performing data transmission in the private network as an example of the decision device. In one embodiment, the decision device may be a first network device, a second network device, or other separately configured devices, and the following embodiments are described by taking the decision device as a separately configured device as an example.
The following describes a method for data transmission in a private network according to an embodiment of the present application with reference to a specific embodiment. The following several embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes. Fig. 4 is a flowchart illustrating a method for data transmission in a private network according to an embodiment of the present application. Fig. 4 illustrates a method for data transmission in a private network according to an embodiment of the present application in terms of terminal (a first terminal and a second terminal), decision device, network device (a first network device and a second network device), and UPF interaction. It should be understood that fig. 4 illustrates an example in which the first terminal and the second terminal characterize a plurality of terminals.
As shown in fig. 4, a method for data transmission in a private network according to an embodiment of the present application may include:
s401, the first terminal sends first data to the first network device.
It should be understood that, in this embodiment of the application, the first terminal may send the first data to the server sequentially through the first network device and the UPF, 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 equipment sends first data to the server through the UPF.
S401-S402 characterize that the first terminal transmits data to the server via a network device serving the first terminal. In one embodiment, the first network device may be a primary network device. It should be understood that the server is not shown in fig. 4.
And S403, the second terminal sends second data to the first network equipment.
S404, the first network device sends second data to the server through the UPF.
S403-S404 characterize the second terminal transmitting data to the server via a network device serving the second terminal. S403-S404 are not sequentially distinguished from S401-S402, and can be executed simultaneously.
S405, the decision device starts a second network device in response to the detection that the transmission reliability parameter value of the first network device is lower than a preset parameter value.
It should be understood that S405 is not sequentially distinguished from S401 to S402 and S403 to S404, and in this embodiment, it is described as an example that after S401 to S402 and S403 to S404, the decision device detects that the transmission reliability parameter value of the first network device is lower than the 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 a numerical value of the transmission reliability parameter of the first network device. The transmission reliability parameter value of the first network device is used to characterize the transmission reliability of the first network device. For example, the lower the bit error rate of the first network device, the higher the transmission reliability of the first network device, the faster the transmission rate of the first network device, the higher the transmission reliability of the first network device, the smaller the transmission delay of the first network device, and the higher the transmission reliability of the first network device.
In one embodiment, the decision device may detect the transmission reliability parameter value of the first network device in real time or in a surrounding manner.
In one embodiment, when the decision device is a first network device, the first network device may obtain its own transmission reliability parameter value. In an embodiment, when the decision device exists independently from the first network device, the first network device may obtain a transmission reliability parameter value of itself, and send the transmission reliability parameter value of the first network device to the decision device, so that the decision device may obtain the transmission reliability parameter value of the first network device.
The decision-making equipment stores a preset parameter value, and the transmission reliability parameter value of the first network equipment is smaller than the preset parameter value representation: there is a risk that the transmission reliability of the first network device may guarantee that the first network device transmits data, but the transmission reliability is reduced. It can also be said that the preset parameter value indicates that the first network device has not failed, but the probability of failure is high.
The decision device 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 decision device may be supported by the second network device to improve the reliability of data transmission.
In one embodiment, the decision device initiating the second network device may be understood as: and the decision-making equipment sends a starting instruction to the second network equipment. And when the second network equipment receives the starting instruction, the second network equipment can be switched from the dormant state to the working state to serve the terminal. It should be understood that fig. 4 illustrates an example where the decision device sends the start instruction to the second network device.
S406, the decision device sends first information to each terminal in the terminal set.
The first information is used for instructing the terminal to send the same data to the first network device and the second network device. That is, the decision device may send the first information to the terminal to notify the terminal to send the same data to the UPF through the first network device and the second network device, so that the UPF selects one of the data to send to the server, and may transmit the data of the terminal by referring to the method shown in fig. 2.
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 data transmission to multiple network devices at the same time, but directly starts the second network device to send the first information to each terminal in the terminal set, because: the number of the terminals in the terminal set is more than one, and when the number of the terminals is large, the decision device detects whether each terminal supports data transmission to a plurality of network devices at the same time, and a long time is consumed.
In this embodiment, after the terminal receives the first information, if the terminal supports simultaneous data transmission to multiple network devices, the same data may be sent to the first network device and the second network device, and if the terminal does not support simultaneous data transmission to multiple network devices, the data may be transmitted in the original manner (through the first network device), because the first network device has not failed yet, the data transmission of the terminal may be ensured.
It should be understood that S406 is characterized in fig. 4 as S406A and S406B:
S406A, the decision device sends the first information to the first terminal.
S406B, the decision device sends the first information to the second terminal.
S406A and S406B are not sequentially distinguished, and they may be performed simultaneously.
S407A, the first terminal sends the third data to the first network device, and sends the third data to the second network device.
S407B, the second terminal sends the fourth data to the first network device, and sends the fourth data to the second network device.
S407A and 407B are not sequentially distinguished, and they may be performed simultaneously.
In an embodiment, to further ensure the reliability of data transmission, before the first terminal and the second terminal transmit data using the second network device, the transmission quality of the second network device may be tested, and when the transmission quality of the second network device is higher (e.g., greater than a preset quality), the terminal simultaneously uses the first network device and the second network device to send the same data to the UPF.
In the embodiment of the present application, in order to save the time for testing 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 may be directly obtained "based on the transmission information that the second network device receives the third data", and the transmission quality of the second network device relative to the second terminal may be obtained "based on the transmission information that the second network device receives the fourth data", which may ensure normal transmission of data from the terminal, and may also detect the transmission quality of the second network device relative to the terminal.
In one embodiment, the transmission information may include at least one of: bit error rate, transmission rate, and transmission delay.
The following description will take an example in which the decision device can obtain the transmission quality of the second network device with respect to the first terminal (hereinafter, referred to as transmission quality in the following embodiments) according to the transmission information. 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 a value (i.e., a parameter value) of a parameter included in the transmission information.
In an embodiment, the decision device stores a mapping relationship between the value of each parameter and the transmission quality, and the decision device may obtain the transmission quality based on the value of each parameter in the transmission information and the mapping relationship. Illustratively, taking the example that the transmission information includes the bit error rate, when the value of the bit error rate is within a first preset range, the transmission quality is a first transmission quality, and when the value of the bit error rate is within a second preset range, the transmission quality is a second transmission quality, and the first transmission quality is higher than the second transmission quality.
In one embodiment, the decision device may also determine the range of transmission quality based on the values of the parameters in the transmission information. Illustratively, taking the bit error rate as an example, when the value of the bit error rate is within a first preset range, the transmission quality is greater than or equal to the first preset transmission quality, and when the value of the bit error rate is within a second preset range, the transmission quality is less than the second preset transmission quality.
It is to be understood that the first predetermined transmission quality and the second predetermined transmission quality are predetermined, the first predetermined transmission quality being higher than the second predetermined transmission quality.
Table one is a mapping relation of the values of each parameter with the transmission quality:
watch 1
Figure BDA0003377436020000131
As in the first table above, for example, when the bit error rate is in the range of a1-a2, the transmission rate is in the range of B1-B2, and the transmission delay is in the range of C1-C2, the transmission quality of the second network device with respect to the first terminal is greater than or equal to the first preset transmission quality.
As such, in the embodiment of the present application, after S407A and S407B, the following steps may be included:
S408A, the decision device determines a target manner for the first terminal to send 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, and the smooth transmission of the data from the first terminal can be ensured. The transmission quality characterization of the second network device relative to the first terminal: the reliability of the second network device for transmitting the data from the first terminal is higher, and the higher the transmission quality of the second network device relative to the first terminal is, the more the smooth transmission of the data from the first terminal can be ensured.
In one embodiment, the target mode includes any one of: a first transmission mode, a second transmission mode, a third transmission mode and a fourth transmission mode. Wherein, the first transmission mode is as follows: the 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 device, 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: the first terminal selects target network equipment from the first network equipment and the second network equipment, and sends data to the UPF through the target network equipment.
It is noted that the fourth transmission mode is a target network device which is determined by the first terminal 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-provisioned. In other words, when the target mode is the fourth transmission mode, the terminal sends data to the UPF according to the appointed network device (i.e. the target network device).
In an embodiment, the decision device stores a mapping relationship among a transmission reliability parameter value, a transmission quality of the second network device relative to the first terminal, and a target mode for the first terminal to send data to the UPF. For example, taking the transmission reliability parameter value as the bit error rate, the bit error rate is in a first bit 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 for the first terminal to send data to the UPF may be the first transmission mode.
For example, the mapping relationship of the "transmission reliability parameter value, the transmission quality of the second network device relative to the first terminal, and the target manner of sending data to the UPF by the first terminal" may refer to table two:
watch two
Figure BDA0003377436020000141
It should be understood that a1-a2, b1-b2, c1-c2, and the first transmission quality range, the second transmission quality range, and the third transmission quality range in table two are illustrative, and actual table two carries specific values.
In an embodiment, the decision device may obtain, according to the transmission reliability parameter value, a level of transmission reliability of the first network device, and further determine, according to the level of transmission reliability of the first network device and transmission quality of the second network device relative to the first terminal, a target mode in which the first terminal sends data to the UPF. The higher the level of the transmission reliability is, the higher the representation transmission reliability is, that is, the more the smooth transmission of the data from the terminal can be ensured.
In one embodiment, the level of transmission reliability may be divided into a first level and a second level, the first level being higher than the second level. When the transmission reliability is of a first grade, the risk of representing the transmission reliability of the first network device is small, and when the transmission reliability is of a second grade, the risk of representing the transmission reliability of the first network device is large. In addition, the decision device may pre-store a first preset quality and a second preset quality, and further divide the transmission quality into three levels, 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 predetermined quality is greater (or higher) than the second predetermined transmission quality.
In one embodiment, the decision device may also detect a time when the first network device receives the third data from the first terminal, e.g., 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 less than a 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 may send a message to the decision device to complete receiving the third data in response to receiving the second data from the first terminal, and similarly, the second network device may send a message to complete receiving the third data in response to receiving the third data from the first terminal. As such, the decision device may regard the time of receiving the message as the time T1 of the first network device receiving the third data from the first terminal, within the preset verification time window after T1, if the decision device does not receive the message of completing the reception of the third data from the second network device, it may determine that the second network device does not receive the third data within the preset verification time window after T1. If the decision device receives a message from the second network device that the third data reception is completed within the preset verification time window after T1, it may be determined that the second network device received 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 to complete receiving the third data in response to receiving the third data from the first terminal. The first network device may record the time T1 of reception in response to receiving the third data from the first terminal, and if the first network device does not receive the message of completing the reception of the third data from the second network device 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. If within the preset verification time window after T1, the first network device receives a message from the second network device that the reception of the third data is completed, it may be determined that within the preset verification time window after T1, the second network device does not receive the third data.
The scenario where the decision device is the second network device may refer to the above-mentioned description of "when the decision device is the first network device".
Based on the above classification of the transmission reliability level and the transmission quality, the following teaching is made to determine the manner in which the 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 relative to the first terminal, the decision device determines that the target mode is the first transmission mode.
If the level of the transmission reliability is the first level and the second network device is greater 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.
And thirdly, if the level of the transmission reliability is a second level and the second network equipment is greater than or equal to a second preset transmission quality relative to the first terminal, the decision equipment determines that the target mode is a second transmission mode.
And fourthly, if the level of the transmission reliability is a second level and the second network equipment is smaller than a second preset transmission quality relative to the first terminal, the decision equipment determines that the target mode is a fourth transmission mode. In the following embodiments and fig. 4, the first target mode is a target mode for the first terminal to transmit data to the UPF, and the second target mode is a target mode for the second terminal to transmit data to the UPF. The first target mode and the second target mode may be the same or different.
S408B, the decision device determines a target manner for the second terminal to send 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 second terminal.
S408B may be referred to in relation to S408A.
S409A, the decision device sends second information to the first terminal, where the second information indicates that the first terminal sends data to the UPF in the first target manner.
Illustratively, the first target mode is a third transmission mode, 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.
S409B, the decision device sends second information to the second terminal, where the second information indicates that the second terminal sends data to the UPF in a second target manner.
Illustratively, the second target mode is the 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 data may be sent to the UPF in a target manner corresponding to the second terminal, which is not shown in fig. 4.
In an 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 second network device has poor transmission quality and is unavailable. For example, fig. 5 illustrates that the decision device sends the first warning information to the first terminal (S410A), and the decision device sends the second warning information to the second terminal (S410B).
In one embodiment, the manner in which the decision device outputs the first warning information may include, but is not limited to: the decision device displays a text prompt message of 'the transmission quality of the second network device is poor or the second network device is unavailable', or the decision device plays a voice of 'the transmission quality of the second network device is poor or the second network device is unavailable', and then a manager of the network device is reminded.
In an 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 unavailable.
In an embodiment, when the decision device sends the second information to the terminal, the decision device may further output third warning information, where the third warning information is used to indicate that the transmission reliability of the first network device is low, the transmission quality of the second network device is poor, for example, the level of the transmission reliability of the first network device is the second level, and the transmission quality of the second network device relative to the first terminal is smaller than the second preset transmission quality.
The mode of the decision device outputting the second alarm information and the third alarm information may refer to the relevant description of the first alarm information.
In the embodiment of the application, when the first network device is not in fault but in the presence of a risk of reliable transmission of the first network device, that is, when the first network device is not in fault but the performance of data transmission is reduced, the second network device is started in advance, so that data transmission of the terminal is not interrupted, and further, the time delay of data transmission is reduced. In addition, for a scenario that the first network device and the second network device serve a plurality of terminals, the decision device may determine a transmission mode suitable for each terminal based on a transmission reliability parameter value of the first network device and a transmission quality of the second network device with respect to each terminal, so that the terminal may transmit data in a transmission mode corresponding to itself, and in consideration of each terminal, may ensure reliability of data transmission,
as described in the above embodiment, in an example 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 multiple terminals at the same time occupies many resources of the decision device, resulting in high resource occupancy of the decision device, in order to improve processing efficiency of the decision device and perform differentiated processing on data transmission of the terminals, in an embodiment, the decision device may send the first information to each terminal in sequence according to a sequence from high to low of service priorities of the terminals in the terminal set.
For example, for a terminal with a higher service priority, the decision device may preferentially send the first information to the terminal, 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 that the transmission quality of the network equipment is poor, the embodiment of the application can ensure the preferential transmission of the data with service priority and ensure the success of important services.
In such an embodiment, referring to fig. 5, the above S406A and S406B may be replaced with S406C: the decision device may send the first information to each terminal in sequence according to the order of the service priority of the terminals in the terminal set from high to low.
