Technical Field

Background

The fifth generation mobile communication system (the 5th generation system,5GS) is applied to the industrial field, and industrial equipment can access the 5G network in a wireless manner through an integrated 5G User Equipment (UE) module or a plug-in (e.g. a user terminal equipment (customer premises equipment, CPE)) or can access the 5G network in a wired manner through a user plane function (user plane function, UPF) network element in a connection network, so that industrial data can be transmitted between the industrial equipment through the 5G network.

In view of the foregoing, it is currently desirable to propose a communication method that enables the industrial equipment at the receiving end to efficiently and accurately obtain the address information of the industrial equipment at the transmitting end, so that both ends can effectively communicate.

2) Enterprise information technology (information technology, IT) domain: including primarily computer and telecommunications systems, for performing various operations such as providing input, storing, retrieving, transmitting, operating and protecting data or information so that data may be exchanged between different fabrics. An enterprise resource planning (ENTERPRISE RESOURCE PLANNING, ERP) in the enterprise IT domain may integrate and manage all resources of the enterprise.

3) Public network domain: for providing public networks (public networks), which are networks used by a plurality of different enterprises in common with different groups of people.

It adopts a programmable memory, in its interior is stored the instruction for executing logic operation, sequence control, timing, counting and arithmetic operation, etc. and utilizes digital or analog input and output to control various mechanical equipments or production processes.

5) Manufacturing execution system MES: the intelligent comprehensive system is integrated with system management software and various hardware, and can collect, control and monitor data in real time from a group of programs sharing data to the whole production process from raw material on-line to finished product warehouse-in through special equipment arranged on a production site. The production efficiency is improved by controlling factory resources such as materials, warehouses, personnel, quality, abnormality, flow instructions, other facilities and the like.

6) And a SCADA (supervisory control and data acquisition) system: is a computer-based production process control and scheduling automation system. The system can monitor and control on-site operation equipment to realize various functions such as data acquisition, equipment control, measurement, parameter adjustment, various signal alarms and the like. An important component of the SCADA comprises a remote terminal unit (remote terminal unit, RTU), a feeder terminal unit (FEEDER TERMINAL unit, FTU), wherein the RTU is responsible for monitoring and control of field signals, industrial equipment. The FTU has the functions of remote control, remote measurement, remote signaling and fault detection, and is communicated with a power distribution automation main station, and is used for providing information required by the running condition and various parameters of a power distribution system and monitoring and controlling, such as a switch state, electric energy parameters and the like, executing commands issued by the power distribution main station, adjusting and controlling power distribution equipment, and realizing the functions of fault positioning, fault isolation, rapid power restoration in a non-fault area and the like.

As shown in fig. 1, in the 5G communication system, a UE may access a user plane (network element) in a core network, such as a user plane function (user plane function, UPF), and a control plane (network element) in the core network, such as AF, etc., through the gNB.

Control plane (network element): the service architecture, that is, the interaction between the control plane network elements adopts the service calling mode, can be adopted to replace the point-to-point communication mode in the traditional architecture. In the service architecture, one control plane network element can open services to other control plane network elements for calling by the other control plane network elements; in point-to-point communication, a specific set of messages exists in a communication interface between control plane network elements, and the messages can only be used by the control plane network elements at two ends of the interface during communication.

The function introduction of the main core network element related in the embodiment of the application is as follows:

As a possible implementation method, the above functions may be implemented by one device, may be implemented by a plurality of devices together, or may be a functional module in one device, which is not specifically limited in the embodiment of the present application.

In the embodiment of the present application, the device for implementing the function of the terminal device may be the terminal device, or may be a device capable of supporting the terminal device to implement the function, for example, a chip system, and the device may be installed in the terminal device. In the technical solution provided in the embodiment of the present application, a terminal device (UE) is described as an example.

A base station may comprise one or more co-sited or non-co-sited transmission reception points. The network devices may also be wireless controllers, centralized units (centralized unit, CUs), and/or Distributed Units (DUs) in the cloud wireless access network (cloud radio access network, C (R) AN) scenario. The network device may also be a server, a wearable device, or an in-vehicle device, etc. For example, the network device in the vehicle-to-everything (vehicle to everything, V2X) technology may be a Road Side Unit (RSU). An access network device will be described below taking a base station as an example. The plurality of network devices in the communication system may be the same type of base station or different types of base stations. The base station may communicate with the terminal device or may communicate with the terminal device through the relay station. A terminal device may communicate with multiple base stations in different access technologies. In the embodiment of the application, the core network device in the communication system is used for realizing at least one of the functions of mobile management, data processing, session management, policy and charging. The names of devices implementing the core network function in the systems of different access technologies may be different, and the embodiment of the present application is not limited to this. Taking a 5G system as an example, the core network device includes, but is not limited to: UPF.

In the embodiment of the present application, the means for implementing the function of the network device may be the network device, or may be a means capable of supporting the network device to implement the function, for example, a chip system, and the apparatus may be installed in the network device.

Referring to fig. 1, since some industrial devices in different production units (e.g., production unit 1 and production unit 2) cannot directly communicate with each other and industrial devices in the production units cannot directly communicate with monitoring/operating devices (MES, SCADA), control devices (e.g., PLC), for this problem, a 5G communication system can be applied to an industrial control system, i.e., a convergence system shown in fig. 1, so that these devices can effectively communicate by accessing a 5G communication network.

Currently, the industrial equipment access to the 5G communication network mainly comprises the following connection modes:

Mode one (i.e., dual-ended wireless connection mode): as shown in fig. 2A, industrial devices at two ends, such as PLC1 and PLC2, that need to communicate with each other can access to the 5G communication network through a wireless connection manner by being hung on a CPE or a built-in module, so as to implement communication.

In an embodiment of the present application, one CPE in fig. 2A may plug in one or more industrial devices.

Mode two (i.e., single-ended wireless connection mode): as shown in (1) in fig. 2B, industrial devices at two ends, such as input/output (I/O) devices and PLCs, that need to communicate with each other, the I/O device on the left may access the gNB (i.e. access the 5G communication network) through a plug-in CPE or a built-in module; the right PLC may be connected to a UPF in the 5G communication system by a wired manner to access the gNB (i.e., access the 5G communication network), so that communication between the I/O device and the PLC may be performed through the 5G communication network.

Or as shown in (2) in fig. 2B, the left I/O device accesses the gNB (i.e. accesses the 5G communication network) through the UPF in the 5G communication system, and the right PLC accesses the gNB (i.e. accesses the 5G communication network) through the external hanging CPE or the built-in module in a wireless connection manner to realize communication.

In an embodiment of the present application, the CPE in fig. 2B may hang one or more industrial devices including I/O devices or PLCs, and the PLC in fig. 2B (1) may be directly connected to the UPF, or may access the UPF through a switch or router.

Mode three (i.e., another single-ended wireless connection mode): as shown in fig. 2C, a common terminal device (e.g., a personal computer (personal computer, PC)) may access the gNB (i.e., access the 5G communication network) through a plug-in CPE or a built-in module, and the enterprise server or the external cross-domain network may access the gNB (i.e., access the 5G communication network) through a UPF in the 5G communication system, so that the common terminal device (e.g., a PC) may access the enterprise server or the external cross-domain network through the 5G communication network.

In industrial communications, industrial communications protocols are used between industrial devices and most are based on internet protocol (internet protocol, IP) communications, such as Modbus/TCP, ethernet/IP, etc., typically, the IP address of the industrial device is allocated by an industrial system, and the IP address of the industrial device is generally static and cannot be dynamically configured and updated, while the IP address of a terminal device (e.g., 5G UE) in the communication system may be allocated by the communication system (e.g., 5G communication system). As shown in fig. 3, in the uplink transmission of the industrial device through the 5G communication network, the industrial device at the transmitting end will send its own IP1 address to the 5G UE1 at the transmitting end, after the IP1 address of the industrial device at the transmitting end is obtained, the 5G UE1 will replace the IP1 address with its own IP2 address, and the 5G UE1 will send its own IP2 address to the industrial device at the receiving end through the 5G UE2 at the receiving end.

In view of the above-mentioned problems, one of the solutions proposed at present is to perform communication through a manually tunneled tunnel by adding an Access Router (AR) to keep the IP address of the industrial equipment at the receiving end unchanged, however, this solution requires high cost and has low communication efficiency. The other is to carry an industrial protocol through a 5G local area network (local area network, LAN) technology to keep the IP address of the industrial equipment at the receiving end unchanged in the communication process, however, the 5G LAN technology has requirements on the terminal equipment, the base station and the core network, and many existing industrial 5G networks do not support 5G LAN, so that the industrial equipment cannot use the 5G LAN technology to realize communication, and the 5G LAN technology has difficulty in realizing cross-domain access and communication.

Accordingly, the present application provides a communication method comprising: the method comprises the steps that a receiving device receives first mapping information and first address information of a first communication device, wherein the first mapping information is used for representing a corresponding relation between the first address information of the first communication device and address information of a first industrial device, and the first communication device is connected with the first industrial device and used for assisting the first industrial device to access a communication network; the receiving device determines the address information of the first industrial device according to the first mapping information and the first address information; based on the address information of the first industrial device, communication with the first industrial device is determined. In the method, the intermediate device establishes address mapping information between the industrial device at the transmitting end and the communication device in advance and transmits the address mapping information to the receiving end, and the receiving end can quickly and accurately obtain the address information of the industrial device at the transmitting end based on the address mapping information so as to determine that the industrial device at the receiving end and the industrial device at the transmitting end can normally communicate.

A scenario to which a communication method according to an embodiment of the present application is applicable may be, but is not limited to, a scenario of bidirectional cooperation of an industrial application with a communication system (e.g., a 5G communication system or a future communication system).

In one embodiment, the receiving device determines to communicate with the first industrial device according to the address information of the first industrial device, and may include: the receiving device checks the address information of the first industrial device with the address information of the first industrial device stored in advance; when the verification is consistent (or identical), the receiving device determines that communication with the first industrial device is possible.

If the receiving device is a second industrial device, the second industrial device may determine to transmit with the first industrial device through a communication network after determining that the check is consistent.

If the receiving device is a second communication device or a UPF network element, the second communication device or the UPF network element may further send a notification message to the second industrial device after determining that the check is consistent, so as to inform or instruct the second industrial device to perform normal communication with the first industrial device through the communication network.

Similarly, if the receiving device is a second communication device or a UPF network element, after the second communication device or the UPF network element determines that the check is inconsistent, the second communication device or the UPF network element may further send a notification message to the second industrial device to inform or instruct the second industrial device not to normally communicate with the first industrial device through the communication network.

In this embodiment of the present application, the transmitting end takes the first industrial device as an example, the receiving end takes the second industrial device as an example, and describes how the first industrial device and the second industrial device communicate through the scheme of the present application, and other industrial devices or apparatuses can refer to the communication modes of the first industrial device and the second industrial device (i.e. the steps S401A-S407A) for communication, and in addition, the number of industrial devices that need to be communicated by the transmitting end and the receiving end in this embodiment of the present application is not limited specifically.

In summary, the present application provides a communication method, which includes: the receiving device receives first mapping information and also receives first address information from the first communication device, wherein the first mapping information is used for representing the corresponding relation between the first address information of the first communication device and the address information of a first industrial device, and the first communication device is connected with the first industrial device and is used for assisting the first industrial device to access a communication network; the receiving device determines address information of the first industrial device according to the first mapping information and the first address information, and further determines to communicate with the first industrial device based on the address information of the first industrial device. In the method, the intermediate device (also called as middleware) can establish address mapping information between the industrial device and the communication device in advance and send the address mapping information to the receiving end, and the receiving end can quickly and accurately obtain the address information of the industrial device at the sending end based on the address mapping information, so that the industrial device at the receiving end and the industrial device at the sending end can realize normal communication.

Referring to fig. 4B, a flowchart of another communication method provided by an embodiment of the present application may specifically include the following steps:

S401B: the intermediate device sends a first indication message to the core network device, the first indication message being used to indicate the encapsulation of the address information of the first industrial device.

Correspondingly, the core network device receives the first indication message. Optionally, the first indication message may include address information of the first industrial device.

In one embodiment, the sending, by the intermediary device, the first indication message to the core network device may include: the intermediate device sends communication indication information to the application function AF network element, and then the AF network element can send a first indication message to the core network device according to the notification indication information. Accordingly, the core network device may receive the first indication message from the AF network element.

Illustratively, the core network device may be, but is not limited to being: a first communication device, or a first UPF network element; the intermediate device (also called middleware) may be, but is not limited to,: industrial management software, or a core network element, or a third communication device.

In an embodiment of the present application, the first communication device may be connected to the first industrial device and used to assist the first industrial device to access a communication network; or may be connected to the first industrial device by a UPF network element and configured to assist the first industrial device in accessing a communication network.

The industrial management software may be a software program or the like for storing and managing information of the industrial device including address information of the industrial device, such as an IP address. The third communication device may be another communication device connected to and communicating with the first industrial device, or may be another communication device connected to and communicating with the first communication device, which is not limited in the present application.

In the embodiment of the present application, the intermediate device may receive the address information of the first industrial device from the transmitting device in advance, and determine whether the address information of the first industrial device needs to be encapsulated, where the transmitting device may be, but is not limited to,: a first industrial device and a first communication device.

In one embodiment, the first indication message may further include, but is not limited to, any one or more of the following:

Address information of the first communication device, port number information, communication protocol type of the first industrial device. The port number information is information of a port number on the first communication device for connection communication with the first industrial device.

S402B: and the core network device encapsulates the address information of the first industrial device according to the first indication message to obtain first information.

In the embodiment of the present application, the first information may include address information of the first industrial device, and may further include other information, for example, information of an application layer, that is, the core network device may encapsulate the address information of the first industrial device together with the information of the application layer to obtain the first information.

In the embodiment of the present application, the core network device encapsulates the address information of the first industrial device, which is understood to be that the first industrial address information is encapsulated in a packet for transmission, so that the address information of the first industrial device can be effectively protected from being changed by the outside during transmission.

As can be seen from the above steps, before communication is performed between the industrial devices, some of the industrial devices need to be checked for address information, and some of the industrial devices do not need to be checked for address information, so that an indication message for indicating the encapsulated address information may not be sent to the core network device for the address information of the industrial devices that need to be checked, and an indication message for indicating the encapsulated address information may be sent to the core network device, and thus, the core network device may determine to encapsulate the address information of the industrial devices in the indication message according to whether there is actually an indication message (as needed) for receiving the function, thereby reducing overhead of the system to a certain extent.

S403B: the core network device transmits the first information to a receiving device.

Accordingly, the receiving device receives the first information from the core network device.

In one embodiment, the core network device sends the first information to the receiving device through a transparent transmission mode; correspondingly, the receiving device receives the first information sent by the core network in a transparent transmission mode; wherein the receiving device may be, but is not limited to being: a second industrial device, or a second communication device, or a second UPF network element.

The second UPF network element may be connected to the second industrial device and configured to assist the second industrial device in accessing the communication network. Or may be connected to the second industrial device by the second communication device and used to assist the second industrial device in accessing the communication network.

Illustratively, the second communication device is, but not limited to,: 5G UE, 5G UE module, user terminal equipment CPE.

S404B: the receiving device unpacks the first information to obtain the address information of the first industrial device.

In the embodiment of the present application, in the step S402B, how the core network device specifically encapsulates the address information of the first industrial device to obtain the first information may be implemented by referring to the existing address encapsulation method. In the step S404B, after receiving the first information, the receiving device may refer to the address encapsulation method to effectively decapsulate the first information by using a corresponding address decapsulation method, so as to obtain the address information of the first industrial device therein.

S405B: the receiving device determines to communicate with the first industrial device according to the address information of the first industrial device.

In one embodiment, the receiving device determines to communicate with the first industrial device according to the address information of the first industrial device, and may include: the receiving device checks the address information of the first industrial device with the address information of the first industrial device stored in advance; when verified as consistent (or identical), the receiving device may determine to communicate with the first industrial device.

If the receiving device is a second industrial device, the second industrial device can determine to perform normal transmission with the first industrial device through the communication network after determining that the check is consistent. If the receiving device is a second communication device or a UPF network element, the second communication device or the UPF network element may further send a notification message to the second industrial device after determining that the check is consistent, so as to inform or instruct the second industrial device to perform normal communication with the first industrial device through the communication network.

Similarly, if the receiving device is a second communication device or a UPF network element, after the second communication device or the UPF network element determines that the check is inconsistent, the second communication device or the UPF network element may further send a communication message to the second industrial device to inform or instruct the second industrial device that the second industrial device cannot normally communicate with the first industrial device through the communication network.

In this embodiment of the present application, the transmitting end takes the first industrial device as an example, the receiving end takes the second industrial device as an example, and describes how the first industrial device and the second industrial device communicate through the scheme of the present application, and other industrial devices or apparatuses can refer to the communication modes (i.e. the steps S401B-S405B) of the first industrial device and the second industrial device for communication.

In summary, the present application provides another communication method, which includes: the core network device receives a first indication message, wherein the first indication message comprises address information of the first industrial device, and the first indication message is used for indicating and packaging the address information of the first industrial device; and then the core network device encapsulates the address information of the first industrial device according to the first indication message to obtain first information, and sends the first information. After the receiving device receives the first information, the first information can be unpacked to obtain the address information of the first industrial device; finally, the receiving device can determine to communicate with the first industrial device according to the address information of the first industrial device. Therefore, in the scheme of the application, on one hand, the address information of the industrial device can be encapsulated by the core network device (UE, UE module, UPF network element and the like), so that the scheme of the application has low requirements on the industrial network and the device, namely, the scheme can be realized in the communication network, and the application range is wide; on the other hand, for the address information of the industrial device which needs to be packaged or does not need to be packaged, as long as the core network device receives the corresponding indication message for indicating the address information of the industrial device to be packaged, the address information of the industrial device contained in the indication message can be effectively packaged, and obviously the core network device performs packaging based on the content indicated by the indication message, namely, the core network device performs the corresponding packaging according to the actual requirement.

The communication method proposed by the above-described scheme of the present application is further described in detail below by means of several specific embodiments.

Embodiment one:

The first embodiment is a specific example of a communication method proposed for the above-mentioned fig. 4A, that is, in an uplink scenario of a dual-end wireless connection (as shown in fig. 2A), a first industrial device at a transmitting end accesses a 5G network in a wireless manner by connecting a first communication device (as UE1 in fig. 5), and a second industrial device at a receiving end accesses the 5G network in a wireless manner by connecting a second communication device (as UE2 in fig. 5). As shown in fig. 5, the specific flow of the first embodiment is as follows:

s501a: the middleware obtains IP address information of the first industrial device from the industrial management software.

The industrial management software may be configured to store and manage information for a plurality of industrial devices (including information for the first industrial device), wherein the information for each industrial device includes IP address information.

S501b: the middleware acquires the IP address information of the UE1 and the corresponding port number from the UE 1.

Optionally, if the industrial management software has acquired the IP address information of the UE1 and the corresponding port number information in the configuration/configuration stage, the UE1 is connected to the first industrial device through the port number 1 of the UE1, and the port number information may include at least one port number including the port number 1.

Therefore, in this step S501b, the middleware may acquire the port number 1 corresponding to the IP address information of the UE1 from the UE1, or may directly acquire the IP address information of the UE1 and the corresponding port number 1 from the industrial management software.

The above steps S501a and S501b may or may not be performed synchronously, and the order of performing the above steps S501a and S501b is not limited in this embodiment.

S502: the middleware establishes a first mapping relation according to the IP address information of the first industrial device, the IP address information of the UE1 and the corresponding port number.

Illustratively, the middleware may establish a first mapping relationship (corresponding to the first mapping information in the above-mentioned scheme of the present application) between the IP address information of the first industrial device, the IP address information of the UE1, and the port number 1.

In some embodiments, if the industrial device to which the UE1 is connected is only a first industrial device, the middleware may not acquire the port number information on the UE1 for connecting the first industrial device in the step S501 b; in this step S502, the middleware may establish a first mapping relationship between the IP address information of the first industrial device and the IP address information of the UE 1.

Steps S501a, S501b and S502 are described by taking as an example the establishment of a first mapping relationship between the IP address information of the first industrial device, the IP address information of the UE1 and the corresponding port number. If other industrial devices exist, the other industrial devices can also be connected with the UE1 through different port numbers on the UE1 to access the 5G network, and the middleware can also refer to the mode to establish the mapping relation among the IP address information of the other industrial devices, the IP address information of the UE1 and the corresponding port numbers.

Similarly, for other UEs and corresponding connected industrial devices, the middleware may also refer to the above manner (e.g. steps S501a, S501b and S502) to establish a mapping relationship, which is not described herein.

In the embodiment of the present application, if each UE (including UE 1) can record the IP address of the industrial device connected to itself, then the UE (including UE 1) may also establish a first mapping relationship between the IP address information (IP address and port number) of itself and the IP address of the corresponding industrial device, and may report the first mapping relationship to the middleware.

S503a: the middleware transmits the first mapping relationship to the UE2.

S503b: the middleware transmits the first mapping relationship to a second industrial device.

In this embodiment, steps S503a and/or S503b may be performed, and if both steps are performed, the order of performing steps S503a and S503b is not particularly limited.

Through the above, the UE2 and/or the second industrial device at the receiving end can effectively obtain the first mapping relationship.

S504a: UE2 receives the IP address information of UE1 from UE 1.

The IP1 address information of the UE1 includes an IP address and a port number 1.

S504b: the second industrial device receives the IP address information of UE1 from UE 1.

Alternatively, the second industrial device may also receive IP address information (IP address and port number 1) from UE1 through UE 2.

In this embodiment, steps S504a and/or S504b may be performed, and if only S504a is performed, i.e. UE2 receives the IP1 address information of UE1 from UE1, then the precondition is that the UE2 should obtain the above-mentioned first mapping relation (i.e. the above-mentioned S503a should be performed). If only S504b is executed, i.e., the second industrial device receives the IP1 address information of UE1 from UE1, then it is assumed that the second industrial device should obtain the above-mentioned first mapping relationship (i.e., the above-mentioned S503b should be executed). If steps S504a and S504b are both performed, the order of performing steps S504a and S504b is not particularly limited in this embodiment.

In addition, the order of executing the steps S503a and/or S503b and the steps S504a and/or S504b is not particularly limited in the embodiment of the present application, that is, the order of receiving the first mapping relationship by the UE2 (may also be a second industrial device) and the order of receiving the IP1 address information from the UE1 by the UE2 (may also be a second industrial device) is not particularly limited in the embodiment of the present application.

S505a: the UE2 determines the IP address information of the first industrial device according to the IP address information of the UE1 and the first mapping relation.

S505b: the second industrial device determines the IP address information of the first industrial device according to the IP address information of the UE1 and the first mapping relationship.

In this embodiment, the above-described steps S505a and/or S505b may be performed.

S506a: the UE2 checks the IP address information of the first industrial device to determine whether to communicate.

Illustratively, the UE2 may acquire pre-stored IP address information of the first industrial device, and in the step S506a, the UE2 may check whether the pre-stored IP address information of the first industrial device is the same as the IP address information of the first industrial device; if the checks are the same, the UE2 determines that the first industrial device and the second industrial device connected to the UE2 can perform normal communication, and if the checks are not the same, the UE2 determines that the first industrial device and the second industrial device connected to the UE2 cannot perform normal communication.

Optionally, the UE2 may also send a communication message to the second industrial device, which may be used to inform or indicate whether the second industrial device may communicate normally with the first industrial device.

S506b: the second industrial device checks the IP address information of the first industrial device to determine whether to communicate.

Illustratively, the second industrial device may acquire the pre-stored IP address information of the first industrial device, and in this step S506b, the second industrial device may verify the pre-stored IP address information of the first industrial device with the IP address information of the first industrial device; if the verification is the same, the second industrial device determines that the second industrial device and the first industrial device can normally communicate through the 5G network, and if the verification is not the same, the second industrial device determines that the second industrial device and the first industrial device cannot normally communicate through the 5G network.

In this embodiment, the above steps S506a and/or S506b may be performed.

In the first embodiment, in the uplink scenario of the dual-end wireless connection, the first industrial device and the connected UE1 of the transmitting end, and the second industrial device and the connected UE2 of the receiving end are taken as examples to describe in detail, and the other industrial devices and the connected UE of the transmitting end, the other industrial devices and the connected UE of the receiving end, and the downlink scenario of the dual-end wireless connection can refer to the steps of the first embodiment to implement the method proposed in the embodiment of the present application, which is not repeated herein.

Uplink scenario for single-ended wireless connection (as shown in fig. 2B): a first industrial device at the transmitting end accesses the 5G network in a wireless manner through the UE1, and a second industrial device at the receiving end accesses the 5G network in a wired manner through the UPF network element (i.e., the UE2 in fig. 5 may be replaced by a UPF network element), so that the UPF network element at the receiving end may obtain a first mapping relationship by referring to the steps corresponding to the UE2 in the first embodiment, and obtain (or restore) address information of the first industrial device based on the first mapping relationship, so that whether the second industrial device at the receiving end and the first industrial device can perform normal communication can be determined, which is not specifically described herein through the embodiment.

According to the first embodiment, for the scenario of double-ended wireless connection or single-ended wireless connection, the address mapping relation between the industrial device of the receiving end and the connected UE can be established through the middleware, so that after the address mapping relation is obtained, the IP address of the industrial device of the transmitting end can be obtained (or restored) quickly and accurately according to the address mapping relation (such as UE2, a second industrial device and a UPF network element), and further, whether normal communication is performed with the industrial device of the transmitting end can be effectively and accurately determined by the industrial device of the receiving end based on the IP address of the industrial device of the transmitting end.

Embodiment two:

The second embodiment is a specific example proposed for the above-mentioned one communication method shown in fig. 4A, that is, in the uplink scenario of the dual-end wireless connection (as shown in fig. 2A), the industrial devices at the transmitting end (such as the industrial device 1 and the industrial device 2 in fig. 6) may access the 5G network in a wireless manner by connecting the first communication device (such as the UE1 in fig. 6), the industrial devices at the receiving end (such as the industrial device 3 and the industrial device 4 in fig. 6) may access the 5G network in a wireless manner by connecting the second communication device (such as the UE2 in fig. 6), and the address mapping relationship is established by the UE1 (which may be regarded as an intermediate device or middleware). As shown in fig. 6, the specific flow of the second embodiment is as follows:

s601a: the UE1 receives an IP address of the industrial device 1 from the industrial device 1.

Illustratively, UE1 communicates with industrial device 1 connection via port number 1, and UE1 may receive the IP address of industrial device 1 via port number 1.

S601b: UE1 receives an IP address of industrial device 2 from industrial device 2.

Illustratively, UE1 communicates with industrial device 2 connection via port number 2, and UE1 may receive the IP address of industrial device 2 via port number 2.

The embodiment does not specifically limit the order of execution of S601a and S601 b.

S602: the UE1 establishes a mapping relation according to the IP address information of the UE1 and the IP addresses of the industrial devices connected with the UE 1.

Illustratively, since industrial device 1 communicates with UE1 via UE 1's port number 1 connection, industrial device 2 communicates with UE1 via UE 1's port number 2 connection. Therefore, the UE1 establishes a mapping relationship (corresponding to the first mapping information in the present application described above) may include the following:

mapping relation 1: namely, the correspondence between the IP address of the industrial device 1, the IP address of the UE1, and the port number 1.

Mapping relation 2: namely, the correspondence between the IP address of the industrial device 2, the IP address of the UE1, and the port number 2.

In the embodiment of the present application, the industrial device to which the UE1 is connected takes the industrial device 1 and the industrial device 2 as an example, and in practice, the UE1 may also be connected to the industrial device 1 or the industrial device 2, or the UE1 may be connected to a plurality of industrial devices including the industrial device 1 and the industrial device 2, so the number of the industrial devices to which the UE1 is connected is not limited, and each of the industrial devices may be performed with reference to the above step S601a or S601b, and in step S602, a mapping relationship between the IP address of each of the industrial devices and the IP address and the corresponding port number of the UE1 is established by the UE 1.

S603: UE1 transmits the mapping relation to UE2.

Accordingly, the UE2 receives the mapping relation.

Through the above steps, the UE2 at the receiving end can obtain the mapping relationship between the IP address of each industrial device connected to the UE1 and the IP address and the corresponding port number of the UE 1.

Optionally, the UE1 may also send the mapping relation to the industrial device (e.g. industrial device 3, 4 shown in fig. 6) to which the UE2 is connected through the UE 2.

S604: UE2 receives the IP address and port number of UE1 from UE 1.

For example, if the industrial device that needs to communicate at this time is the industrial device 1, the industrial device 1 will send its own IP to the UE1, and after the UE1 can receive the IP address of the industrial device 1 through the port number 1, the UE1 sends its own address of the UE1 and the port number 1 to the UE2. Accordingly, UE2 receives the IP address and port number 1 of UE1 from UE 1.

If the industrial device to be communicated is the industrial device 2, the industrial device 2 will send its own IP to the UE1, and the UE1 will send its own address of the UE1 and the port number 2 to the UE2 after the UE1 receives the IP address of the industrial device 1 through the port number 2. Accordingly, UE2 receives the IP address and port number 2 of UE1 from UE 1.

S605: the UE2 determines the IP address of the corresponding industrial device to which the UE1 is connected according to the IP address and port number of the UE1 and the mapping relationship.

Illustratively, in the above step S604, if the UE2 receives the IP address and the port number 1 of the UE1 from the UE1, the UE2 may determine the IP address of the industrial device 1 according to the mapping relation 1 in the above mapping relation. If UE2 receives the IP address and port number 2 of UE1 from UE1, UE2 can determine the IP address of industrial device 2 according to mapping relation 2 in the mapping relation.

S606a: UE2 transmits the IP address of the corresponding industrial device to which UE1 is connected to industrial device 3 to which UE2 is connected.

For example, if the UE2 transmits the IP address of the industrial device 1 to the industrial device 3 to which the UE2 is connected, the industrial device 3 may continue to execute the following case 1 in step S607a after receiving the IP address of the industrial device 1.

If the UE2 transmits the IP address of the industrial device 2 to the industrial device 3 to which the UE2 is connected, the industrial device 3 may continue to execute the following step S607a after receiving the IP address of the industrial device 2.

S606b: UE2 transmits the IP address of the corresponding industrial device to which UE1 is connected to industrial device 4 to which UE2 is connected.

For example, if the UE2 transmits the IP address of the industrial device 1 to the industrial device 4 to which the UE2 is connected, the industrial device 4 may continue to execute the following case 1 in step S607b after receiving the IP address of the industrial device 1.

If the UE2 transmits the IP address of the industrial device 2 to the industrial device 4 to which the UE2 is connected, the industrial device 4 may continue to execute the following step S607b after receiving the IP address of the industrial device 2.

S607a: the industrial device 3 checks to determine whether to communicate.

That is, the industrial device 3 checks the IP address of the corresponding industrial device to which the UE1 is connected to determine whether to communicate.

Case 1: after the industrial device 3 receives the IP address of the industrial device 1, the IP address of the industrial device 1 is checked, that is, the IP address of the industrial device 1 and the pre-stored IP address of the industrial device 1 can be checked, and if the check is the same, the industrial device 3 can perform normal communication with the industrial device 1 through a network; if the verification is not the same, the industrial device 3 may not communicate with the industrial device 1 normally through the network.

Case 2: after the industrial device 3 receives the IP address of the industrial device 2, the IP address of the industrial device 2 is checked, that is, the IP address of the industrial device 2 and the pre-stored IP address of the industrial device 2 can be checked, and if the check is the same, the industrial device 3 can normally communicate with the industrial device 2 through a network; if the verification is not the same, the industrial device 3 may not communicate with the industrial device 2 normally through the network.

S607b: the industrial device 4 checks to determine whether to communicate.

That is, the industrial device 4 checks the IP address of the corresponding industrial device to which the UE1 is connected to determine whether to communicate.

Case 1: after the industrial device 4 receives the IP address of the industrial device 1, the IP address of the industrial device 1 is checked, that is, the IP address of the industrial device 1 and the pre-stored IP address of the industrial device 1 can be checked, and if the check is the same, the industrial device 4 can perform normal communication with the industrial device 1 through a network; if the verification is not the same, the industrial device 4 may not communicate with the industrial device 1 normally via the network.

Case 2: after the industrial device 4 receives the IP address of the industrial device 2, the IP address of the industrial device 2 is checked, that is, the IP address of the industrial device 2 and the pre-stored IP address of the industrial device 2 can be checked, and if the check is the same, the industrial device 4 can normally communicate with the industrial device 2 through a network; if the verification is not the same, the industrial device 4 may not communicate with the industrial device 2 normally over the network.

In the second embodiment, the industrial device to which the UE2 is connected is exemplified by the industrial device 3 and the industrial device 4, and in practice, the UE2 may also be connected to the industrial device 3 or the industrial device 4, or the UE2 may be connected to a plurality of industrial devices including the industrial device 3 and the industrial device 4, so that the number of industrial devices to which the UE2 is connected is not limited, and each industrial device to which the UE2 is connected may be performed with reference to the above steps S606a and S607a, or S606b and S607b, so that the industrial device to which the UE2 is connected may check the IP address of the industrial device from the receiving end to determine whether to perform normal communication with the industrial device of the receiving end.

In the embodiment of the present application, the industrial device 1 and the industrial device 2 may be regarded as a transmitting end or a receiving end, and the industrial device 3 and the industrial device may also be regarded as a transmitting end or a receiving end. When the UE2 and the industrial device 3 and the industrial device 4 are used as the transmitting end and the UE1 and the industrial device 2 are used as the receiving end, the industrial device 3 and the industrial device 4 can establish an address mapping relationship through the UE2, specifically, the address mapping relationship can be established through the UE1 by referring to the industrial device 1 and the industrial device 2, which is not described in detail herein. After receiving the IP address of the UE2, the UE1 as the receiving end may obtain the IP address of the industrial device 3 and/or the industrial device 4 through the mapping relationship, and then the industrial device 1 and/or the industrial device 2 may check whether the IP address of the industrial device 3 and/or the IP address of the industrial device 4 are correct, so as to determine whether normal communication with the industrial device 3 and/or the working device 4 is possible, which will not be described in detail herein.

In some embodiments, the industrial device 1 and the industrial device 2 may also be connected to different UEs, and the industrial device 1 and the industrial device 2 may respectively establish an address mapping relationship through the correspondingly connected UEs. The industrial device 3 and the industrial device 4 may be connected to different UEs, and the industrial device 3 and the industrial device 4 may respectively establish an address mapping relationship through the correspondingly connected UEs, which is not particularly limited in the present application, and may be flexibly implemented in reference to the second embodiment.

Embodiment III:

The third embodiment is a specific example proposed for the communication method shown in fig. 4B, that is, in an uplink scenario of a dual-end wireless connection (as shown in fig. 2A) or a single-end wireless connection (as shown in fig. 2B), an industrial device at a transmitting end may access a 5G network through UE1 in a wireless connection manner, or access the 5G network through a UPF1 network element in a wired connection manner; similarly, the industrial device at the receiving end can also access the 5G network in a wireless manner through connecting with the UE2 or access the 5G network in a wired connection manner through connecting with the UPF2 network element, which connection manner is adopted by the two ends of the embodiment of the present application is not particularly limited, and before the sending end sends the IP address, the middleware indicates the IP address of the industrial device to be packaged to the UE1 or the UPF1 network element at the sending end. As shown in fig. 7, the specific flow of the third embodiment is as follows:

S701: the middleware obtains the IP address of the industrial device 1 and determines that it needs to be encapsulated.

Illustratively, the middleware may obtain the IP address of the industrial device 1 from the industrial device 1; or the middleware may obtain the IP address of the industrial device 1 from industrial management software; or the middleware may obtain the IP address of the industrial device 1 from a communication device connected to the industrial device 1. The way in which the middleware obtains the IP address of the industrial device 1 is not particularly limited in the embodiment of the present application. In addition, the middleware may also acquire IP addresses of a plurality of industrial devices including the IP address of the industrial device 1, and the industrial device 1 in the step S701 is only one example.

This step S701 is an optional step, and the middleware may also have acquired and stored the IP address of at least one industrial device (including the IP address of the industrial device 1) in advance, and know which industrial devices need to be encapsulated and which industrial devices do not need to be encapsulated. For the IP address of the industrial device that needs to be encapsulated, the middleware may simultaneously instruct to encapsulate the IP address of the industrial device when sending the IP address of the industrial device.

S702: the middleware sends notification indication information to the AF network element.

The notification indication information may be used to indicate an IP address encapsulating the industrial device 1.

Optionally, the notification indication information includes an IP address of the industrial device 1.

S703: the AF network element sends a first indication message to the UE 1.

Correspondingly, the UE1 receives the first indication message, where the first indication message includes the IP address of the industrial device 1, and the first indication message is used to indicate that the IP address of the industrial device 1 is encapsulated.

Optionally, the first indication message may further include any one or more of the following:

The IP address of UE1, the port number on UE1 for connection communication with the industrial device 1, the type of communication protocol of UE1 with the industrial device 1.

S704: the UE1 encapsulates the IP address of the industrial device 1 according to the first indication message, to obtain first information.

Alternatively, the industrial device 1 may be packaged together with other information (such as information of an application layer) to obtain the first information. The UE1 may be encapsulated with reference to an existing address encapsulation manner.

S705: UE1 sends the first information to UE 2.

Accordingly, the UE2 receives the first information.

S706: the UE2 decapsulates the first information to obtain the IP address of the industrial device 1.

Optionally, before performing the step S706, the UE2 may further receive, by the AF network element, a second indication message (or information) from the middleware, where the second indication message (or information) is used to instruct the UE2 to decapsulate the first information.

The UE2 may perform the decapsulation of the first information by referring to an address decapsulation manner corresponding to the address encapsulation manner.

S707: the UE2 transmits the IP address of the industrial device 1 to the industrial device 2.

The UE2 is in connected communication with the industrial device 2 and may be used to assist the industrial device 2 in accessing a network.

S708: the industrial device 2 checks the IP address of the industrial device 1 to determine whether to communicate.

For example, the industrial device 2 may check the IP address of the industrial device 1 with the IP address of the industrial device stored in advance, and if the check is the same, the industrial device 2 may determine that normal communication with the industrial device 1 is possible. If the verification is not the same, the industrial device 2 may determine that normal communication with the industrial device 1 is not possible.

Alternatively, the IP address of the industrial device 1 may be checked by the UE2 to determine whether the industrial device 2 to which the UE2 is connected communicates and the industrial device 1 can normally communicate.

The industrial device 2 in steps S707 and S708 is an example, and in practice, the industrial device to which the UE2 (or the UPF2 network element) is connected includes, but is not limited to, the industrial device 2, and other industrial devices to which the UE2 (or the UPF2 network element) is connected may be executed with reference to the industrial device 2, which is not described herein in detail.

Uplink scenario for single-ended wireless connection (as shown in fig. 2B):

The industrial device 1 at the transmitting end accesses the 5G network in a wired connection manner through the UPF1 network element (i.e. the UE1 in fig. 7 is replaced by the UPF1 network element), and the industrial device 2 at the receiving end accesses the 5G network in a wireless connection manner through the UE2, so that the UPF1 network element at the transmitting end may be executed with reference to the steps corresponding to the UE1 in the third embodiment (for example, receiving the first indication message, encapsulating the IP address of the industrial device 1, and transmitting the encapsulated first information), which will not be described in detail in the embodiments herein; or alternatively

The industrial device 1 at the transmitting end accesses the 5G network in a wireless connection manner through the UE1, the industrial device 2 at the receiving end accesses the 5G network in a wired connection manner through the UPF2 network element (i.e. the UE2 in fig. 7 is replaced by the UPF2 network element), and then the UPF2 network element at the receiving end can refer to the steps corresponding to the UE2 in the third embodiment (such as receiving the first information, decapsulating the first information to obtain the IP address of the industrial device 1, and transmitting the IP address of the industrial device 1) which will not be specifically described in the embodiments herein.

In addition, the communication between the industrial devices can be flexibly realized by referring to the method shown in the third embodiment for both the downlink scenario of the double-ended wireless connection and the downlink scenario of the single-ended wireless connection, which will not be described by way of specific examples.

According to the third embodiment, whether the IP address of the industrial device at the transmitting end needs to be encapsulated or not can be determined according to the condition of communication between the industrial devices, so that for the IP address of the industrial device at the transmitting end, the middleware can send an indication message carrying the IP address of the industrial device to the UE or the UPF network element (which can be called as a 5G Anchor) connected with the industrial device through the AF network element to indicate the IP address of the industrial device to encapsulate the industrial device, so that the overhead generated in the encapsulation process can be reduced, further, the UE or the UPF network element transmits the encapsulated IP address to the UE or the UPF network element at the receiving end, the UE or the UPF network element at the receiving end performs decapsulation, the IP address of the industrial device at the transmitting end can be accurately obtained, and further, the UE or the UPF network element at the receiving end can also obtain the IP address of the industrial device at the transmitting end, so that the IP address of the industrial device can be effectively checked to determine whether to perform normal communication.
