[0073] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0074] With the gradual increase in the penetration rate of the 5th Generation Mobile Communication Technology (5G), the integration of 5G and industry has gradually evolved from factory-level auxiliary production to production-line-level core production. At present, most industrial sites use wired networking. Station-level centralized controllers (such as Programmable Logic Controllers (PLCs)) are connected by wire to form an industrial ring network. The PLC is connected southward to the IO actuator by wire, and data is transmitted between the PLC and the IO through the industrial ethernet protocol; the IO is connected southward to the physical device by wire, and data is transmitted between the IO and the physical device through the industrial bus protocol. After the cloud-based PLC is deployed on the edge cloud side through 5G, a wireless link between the controller and the IO can be achieved.

[0075] At present, there are many types of industrial transmission protocols. The mainstream industrial Ethernet protocols include serial communication protocols (ModbusTCP), automation bus standards for industrial Ethernet technology (Profinet), Ethernet control automation technology (Ethercat), etc. In the case of industrial equipment initialization, in order to further reduce latency, industrial Ethernet needs to address all devices within the local area network. Taking Ethercat as an example, all devices on the end side will be addressed in the order of their wired connections. When addressing sequentially, the address of a slave station is determined by its connection position within the network segment, and a negative number is used to represent the position of each slave station within the network segment determined by the wiring order. When the sequential addressing sub-message passes through each slave station device, its position address is incremented by 1. When a slave station receives a message, if the address is zero, it is its own message. This content can be combined with Figure 1 for understanding, Figure 1 which is a schematic diagram of sequential addressing.

[0076] After completing sequential addressing, its assigned order is its logical address bit, and subsequently the master station can use the station address independent of the physical position to address the slave station.

[0077] At present, under wired networking, different terminals can achieve sequential addressing according to the access order and position, thereby completing the determination of the slave station address. Existing wireless solutions can already report information such as the terminal IP, port number, and device name, but there are the following problems in a wireless environment:

[0078] 1. Devices cannot allocate the slave station address through sequential means;

[0079] 2. Devices do not have an actual physical access order position, and it is necessary to use network-side means to implement the mapping of the address and the order. However, the subsequent operation of the industrial network requires packet assembly and forwarding based on the sequential addressing structure.

[0080] This patent proposes an addressing method for industrial devices in a wireless environment. On the one hand, it realizes the allocation of the slave station address through broadcast or multicast information; on the other hand, it realizes the sequential allocation of different slave station addresses by maintaining a mapping table on the network side.

[0081] Based on this, an embodiment of this application provides an addressing method, which is applied to a network device, Figure 2 which is a schematic flow diagram of the addressing method of the embodiment of this application; as Figure 2 shown, this method includes:

[0082] Step 201: In a wireless environment, receive the first address information reported by at least one terminal and the first identification information of the first industrial device hung under each terminal.

[0083] Step 202: When the first industrial device initiates addressing, obtain the first data packet sent by the first industrial device based on the first identification information; the first data packet includes the second address information of the first industrial device.

[0084] Step 203: Determine the addressing mapping information of the first data packet based on the first address information and the second address information.

[0085] Step 204: Send the addressing mapping information to the terminal; the addressing mapping information is used to allocate the initial addresses of the terminal and the second industrial device subordinate to the first industrial device.

[0086] It should be noted that the network device can be any network device and is not limited here. As an example, the network device can at least include a base station, a server, etc. The terminal can also be determined according to the actual situation and is not limited here. As an example, the terminal can be a smart phone, a tablet computer, a desktop computer, a notebook, a client, etc.

[0087] In step 201, the wireless environment can be determined according to the actual situation and is not limited here. As an example, the wireless environment can be a wireless networking environment.

[0088] Receive the first address information reported by at least one terminal and the first identification information of the first industrial device hung under each terminal; where the first address information can be the terminal IP address; the first identification information can be determined according to the actual situation and is not limited here. As an example, the first identification information can include at least one of the following: the I / O information of the first industrial device; the identity information of the first industrial device. Where the I / O information can include the IO number; the identity information of the first industrial device can include the device number. The first industrial device hung under can be determined according to the actual situation and is not limited here. As an example, the first industrial device hung under can be abbreviated as the hung-under device and can be a master station.

[0089] As an example, in a wireless environment, when a terminal accesses, it can trigger the reporting of information such as the terminal IP address and the IO number and device number of the hung-under device along with the access information or configuration event.

[0090] In step 202, the first data packet includes the second address information of the first industrial device; where the second address information can be understood as the address information set for the industrial devices hung under different terminals and can be abbreviated as the set address.

[0091] As an example, after the master station triggers the setting of addressing, it will send the address information that will be set for the industrial devices hung under different terminals.

[0092] In step 203, the specific determination process of determining the addressing mapping information of the first data packet based on the first address information and the second address information can be determined according to the actual situation and is not limited herein. As an example, the first address information may include an IP address; the second address information may include a set address, and determining the addressing mapping information of the first data packet based on the first address information and the second address information may include: configuring the sequential address and logical address of the first data packet; determining the addressing mapping information of the first data packet based on the IP address, the set address, the sequential address, and the logical address.

[0093] In step 204, the specific distribution process of distributing the addressing mapping information to the terminal can be determined according to the actual situation and is not limited herein. As an example, the specific distribution process may include distributing the addressing mapping information to the terminal by means of broadcast, multicast, and / or unicast.

[0094] The addressing mapping information is used to allocate the initial addresses of the terminal and the second industrial device subordinate to the first industrial device. It can be understood that the addressing mapping information is distributed to the terminal by means of broadcast, multicast, and / or unicast to complete initialization.

[0095] In one embodiment, the first identification information includes at least one of the following:

[0096] The input or output I / O information of the first industrial device;

[0097] The identity information of the first industrial device.

[0098] It should be noted that the I / O information may include an IO number; the identity information of the first industrial device may include a device number. As an example, the first identification information may include information such as the IO number and device number of the subordinate device.

[0099] In one embodiment, the first address information includes an IP address; the second address information includes a set address, and determining the addressing mapping information of the first data packet based on the first address information and the second address information includes:

[0100] Configuring the sequential address and logical address of the first data packet;

[0101] Determining the addressing mapping information of the first data packet based on the IP address, the set address, the sequential address, and the logical address.

[0102] In this embodiment, the IP address, the setting address, the sequential address, and the logical address can all be determined according to the actual situation and are not limited herein. As an example, the IP address may include 192.168.1.1, 192.168.1.2, 192.168.1.3, 192.168.1.4. The setting address may include 162.108.1.1, 162.108.1.2, 162.108.1.3, 162.108.1.4. The sequential address may include 1, 2, 3, 4. The logical address may include AA, AB, AC, AD.

[0103] Determine the addressing mapping information of the first data packet based on the IP address, the setting address, the sequential address, and the logical address; wherein, the addressing mapping information can be determined according to the actual situation and is not limited herein. As an example, the addressing mapping information may be an addressing information mapping table. As an example, determining the addressing mapping information of the first data packet based on the IP address, the setting address, the sequential address, and the logical address can be understood as determining the addressing information mapping table of the first data packet based on the IP address, the setting address, the sequential address, and the logical address. Among them, the addressing information mapping table may be the correspondence relationship of the IP address, the setting address, the sequential address, and the logical address. For example, the correspondence relationship where the IP address is 192.168.1.1, the setting address is 162.108.1.1, the sequential address is 1, and the logical address is AA; the correspondence relationship where the IP address is 192.168.1.2, the setting address is 162.108.1.2, the sequential address is 2, and the logical address is AB; the correspondence relationship where the IP address is 192.168.1.3, the setting address is 162.108.1.3, the sequential address is 3, and the logical address is AC; the correspondence relationship where the IP address is 192.168.1.4, the setting address is 162.108.1.4, the sequential address is 4, and the logical address is AD.

[0104] In practical applications, a new service initialization enhancement module is added on the base station side. The module mainly realizes three functions: First, perform traffic splitting according to the service-side IP or the terminal IP, and split the setting address packet to the service initialization enhancement module. Second, the service initialization enhancement module identifies the reception flag according to the setting address packet and parses the setting address data. Third, the service initialization enhancement module realizes the mapping of the address information and the terminal IP information here, and at the same time assigns different sequence numbers and logical addresses to different addresses to form an addressing information mapping table.

[0105] In one embodiment, the step of sending the addressing mapping information to the terminal includes:

[0106] Send the addressing mapping information to the terminal by means of broadcast, multicast, and / or unicast.

[0107] In practical applications, due to the wireless access of the overall industrial control and other capabilities, the ability to assign the addresses of industrial slave devices through wired broadcast information during the initialization of the original industrial network needs to be carried by the 5G network, and the addresses, sequences, and logical addresses of the slave stations are assigned through broadcast, multicast, or unicast information.

[0108] In a wireless environment, based on the event trigger of the master station triggering the addressing information, after the master station triggers the slave station address setting to form an addressing information mapping table, the addresses of the terminals on the terminal side can be configured by means of broadcast, multicast, or unicast to complete the initialization. Therefore, three methods for sending packets are formed.

[0109] In one embodiment, the sending the addressing mapping information to the terminal by means of broadcast includes:

[0110] Send the addressing mapping information to the terminal by means of broadcasting through a preset information block SIB.

[0111] In this embodiment, the preset information block can be determined according to the actual situation and is not limited here. As an example, the preset information block can be denoted as SIB1, and the SIB1 message is extended. A new nonCriticalExtensionSIB1 - Slave station - informationRequest - IEs is defined. That is, the IE carries the addressing mapping information.

[0112] In one embodiment, the sending the addressing mapping information to the at least one terminal by means of broadcasting through a preset information block SIB includes:

[0113] Obtain the element information IE of the SIB; the IE carries the addressing mapping information;

[0114] Send the IE to the terminal.

[0115] In practical applications, SIB1 is broadcast to all terminals within the cell to expand the SIB1 message. New nonCriticalExtension SIB1-Slave station-informationRequest-IEs are defined. That is, the IE carries the addressing mapping information. Each user decodes the PDCCH according to the SI-RNTI, and the users whose decoded SIB1 information contains SIB1-Slavestation-informationRequest-IEs configure their device information according to this information.

[0116] In one embodiment, the step of sending the addressing mapping information to the terminal by multicast includes:

[0117] Obtain the group identifier of each terminal;

[0118] Determine the terminals belonging to the same group based on the group identifier;

[0119] Send the addressing mapping information to the terminals in the same group.

[0120] In this embodiment, the group identifier can be determined according to the actual situation and is not limited herein. As an example, the group identifier can be denoted as group session. Determining the terminals belonging to the same group based on the group identifier can be understood as forming a multicast for the UEs in the same group by identifying the group session.

[0121] In practical applications, for the terminals that have completed multicast configuration, the base station side can form a multicast for the UEs in the same group by identifying the group session, use the multicast IP address as the destination address, and all hosts that have joined the "group" will receive the data packets sent to this group. The data packets are the relevant information such as the set addressing. The slave station completes the address setting according to the set addressing packet.

[0122] In one embodiment, the step of sending the addressing mapping information to the terminal by unicast includes:

[0123] Send the addressing mapping information to the terminal by unicast according to the IP address of each terminal.

[0124] In this embodiment, as an example, the IP address addressing mapping information can be an IP address addressing mapping table. Sending the addressing mapping information to the terminal by unicast according to the IP address of each terminal can be sending the addressing mapping table of each terminal to the terminal by unicast.

[0125] In practical applications, for a terminal with a mapping table already formed, the base station can combine the set address and the logical address separately according to the IP address and send them as unicast. In this case, the resource occupancy is relatively high compared to the broadcast and multicast cases.

[0126] In this embodiment, addressing is initiated by the first industrial device. Based on the first identification information of the first industrial device attached to each terminal, a data packet including the second address information of the first industrial device sent by the first industrial device is obtained, and then the addressing mapping information of the first data packet is determined. The addressing mapping information is sent to the terminal to allocate the initial addresses of the terminal and the second industrial device subordinate to the first industrial device. That is, the sequential allocation of the addresses of the second industrial device subordinate to the first industrial device is realized by maintaining the addressing mapping information on the network side.

[0127] Correspondingly, an embodiment of the present application further provides an addressing method, which is applied to a terminal. Figure 3 It is another flowchart of the addressing method according to the embodiment of the present application; as Figure 3 shown, the method includes:

[0128] Step 301: In a wireless environment, report the first address information of the terminal and the first identification information of the first industrial device attached to the terminal to a network device; the first identification information is used for the network device to obtain the first data packet sent by the first industrial device based on the first identification information when the first industrial device initiates addressing; the first data packet includes the second address information of the first industrial device; and determine the addressing mapping information of the first data packet based on the first address information and the second address information.

[0129] Step 302: Receive the addressing mapping information sent by the network device.

[0130] Step 303: Use the addressing mapping information to allocate the initial addresses of the terminal and the second industrial device subordinate to the first industrial device.

[0131] It should be noted that the network device can be any network device and is not limited here. As an example, the network device can at least include a base station, a server, etc. The terminal can also be determined according to the actual situation and is not limited here. As an example, the terminal can be a device including a smart phone, a tablet computer, a desktop computer, a notebook, a client, etc.

[0132] In step 301, the wireless environment can be determined according to the actual situation and is not limited here. As an example, the wireless environment can be a wireless networking environment.

[0133] Report the first address information of the terminal and the first identification information of the first industrial device hung under the terminal to the network device; wherein, the first address information may be the terminal IP address; the first identification information may be determined according to the actual situation and is not limited herein. As an example, the first identification information may include at least one of the following: the I / O information of the first industrial device; the identity information of the first industrial device. Wherein, the I / O information may include the IO number; the identity information of the first industrial device may include the device number. The first industrial device hung under may be determined according to the actual situation and is not limited herein. As an example, the first industrial device hung under may be abbreviated as the hung device and may be the master station.

[0134] As an example, in a wireless environment, when the terminal accesses, it may trigger the reporting of information such as the terminal IP address and the IO number and device number of the hung device along with the access information or configuration event.

[0135] The first data packet includes the second address information of the first industrial device; wherein, the second address information may be understood as the address information set for the industrial devices hung under different terminals and may be abbreviated as the set address.

[0136] As an example, after the master station triggers the setting of addressing, it will send down the address information that will be set for the industrial devices hung under different terminals.

[0137] The specific determination process of determining the addressing mapping information of the first data packet based on the first address information and the second address information may be determined according to the actual situation and is not limited herein. As an example, the first address information may include the IP address; the second address information may include the set address, and determining the addressing mapping information of the first data packet based on the first address information and the second address information may include: configuring the sequential address and logical address of the first data packet; determining the addressing mapping information of the first data packet based on the IP address, the set address, the sequential address, and the logical address.

[0138] In step 302, the receiving of the addressing mapping information sent by the network device may be determined according to the actual situation and is not limited herein. As an example, the receiving of the addressing mapping information sent by the network device may include receiving the addressing mapping information sent by the network device in a broadcast, multicast, and / or unicast manner.

[0139] In step 303, allocating the initial addresses of the terminal and the second industrial device subordinate to the first industrial device by using the addressing mapping information may be understood as allocating the initial addresses of the terminal and the second industrial device subordinate to the first industrial device by using the addressing mapping information to complete the initialization.

[0140] In one embodiment, receiving the addressing mapping information sent by the network device includes:

[0141] Receiving the addressing mapping information sent by the network device by means of broadcast, multicast, and / or unicast.

[0142] In practical applications, due to the wireless access of overall industrial control and other capabilities, the ability to assign industrial slave device addresses through wired broadcast information during the initialization of the original industrial networking needs to be carried by the 5G network, and the assignment of slave addresses, sequences, and logical addresses is achieved through broadcast, multicast, or unicast information.

[0143] In a wireless environment, based on the event trigger of the master station triggering the addressing information, after the master station triggers the slave address setting to form an addressing information mapping table, the addresses of the terminals on the terminal side can be configured by means of broadcast, multicast, or unicast to complete the initialization. Therefore, three methods for sending packets are formed.

[0144] In one embodiment, receiving the addressing mapping information sent by the network device by means of broadcast includes:

[0145] Receiving the addressing mapping information sent by the network device by means of broadcasting through a preset information block SIB.

[0146] In this embodiment, the preset information block can be determined according to the actual situation and is not limited here. As an example, the preset information block can be denoted as SIB1, an extended SIB1 message. A new nonCriticalExtensionSIB1 - Slave station - informationRequest - IEs is defined. That is, the IE carries the addressing mapping information.

[0147] In one embodiment, receiving the addressing mapping information sent by the network device by means of broadcasting through a preset information block SIB includes:

[0148] Receiving the element information IE of the SIB sent by the network device; the IE carries the addressing mapping information.

[0149] In practical applications, SIB1 is broadcast to all terminals within the cell to expand the SIB1 message. A new nonCriticalExtension SIB1-Slave station-informationRequest-IEs is defined. That is, the IE carries the addressing mapping information. Each user decodes the PDCCH according to the SI-RNTI, and the user whose SIB1 information contains SIB1-Slavestation-informationRequest-IEs configures its own device information according to this information.

[0150] To better understand this application, a practical application scenario is exemplified here. The addressing method is an addressing method for industrial devices in a wireless environment, and the network device is a base station.. This method mainly involves two parts. The first part: When the master station triggers the setting of addressing, a mapping table is formed on the base station side according to the terminal reported information and the setting addressing packet to clarify the terminal IP, and the corresponding relationship between the setting addressing address, sequential address and logical address is set; The second part: After the mapping is completed, the base station issues the setting addressing and other information according to the mapping table.

[0151] I. Mapping scheme for slave station IP address, logical address and MAC address under wireless networking (supplementary module details)

[0152] In a wireless environment, when the terminal accesses, it can trigger the reporting of the terminal IP address and the IO numbers, device numbers, etc. of the subordinate devices along with the access information or configuration events. After the master station triggers the setting of addressing, it will issue the address information to be set for the industrial devices subordinate to different terminals. At this time, a new service initialization enhancement module is added on the base station side, and the module mainly realizes three functions:

[0153] 1. Perform traffic splitting according to the service side IP or terminal IP, and split the setting address packet to the service initialization enhancement module.

[0154] 2. The service initialization enhancement module identifies the reception flag according to the setting address packet and parses the setting address data. This content can be combined with Figure 4 for understanding, Figure 4 which is a schematic diagram of the address data in the embodiment of this application.

[0155] 3. The service initialization enhancement module realizes the mapping of the address information and the terminal IP information here, and at the same time assigns different sequential numbers and logical addresses to different addresses to form an addressing information mapping table. This addressing information mapping table can be understood in combination with Table 1, and Table 1 is the addressing information mapping table.

[0156] Table 1

[0157]

[0158]

[0159] II: Slave station address allocation scheme under wireless networking.

[0160] Due to the wireless access of the overall industrial control and other capabilities, the ability to allocate the addresses of industrial slave devices through wired broadcast information during the initialization of the original industrial networking needs to be carried by the 5G network, and the allocation of slave station addresses, sequences, and logical addresses is achieved through broadcast, multicast, or unicast information.

[0161] In a wireless environment, based on the event trigger of the master station triggering the addressing information, after the master station triggers the slave station address setting to form an addressing information mapping table, the addresses of the terminals on the terminal side can be configured through broadcast, multicast, or unicast to complete the initialization. Therefore, three methods for sending packets are formed.

[0162] Method 1: Broadcast distribution.

[0163] SIB1 is broadcast to all terminals within the cell to expand the SIB1 message. A new nonCriticalExtension SIB1-Slave station-informationRequest-IEs is defined. Each user decodes the PDCCH according to the SI-RNTI, and the users whose sib1 information decoded contains SIB1-Slave station-informationRequest-IEs configure their device information according to this information. This content can be understood in combination with Figure 5 and Figure 6 for understanding. Figure 5 is the schematic diagram of the code program of the SIB1 message in the embodiment of this application; Figure 6 is the schematic diagram for the explanation of the SIB1 message in the embodiment of this application.

[0164] Method 2: Multicast distribution.

[0165] For the terminals that have completed the multicast configuration, the base station side can form a multicast for the UEs in the same group by identifying the group session, use the multicast IP address as the destination address, and all the hosts that have joined the "group" will receive the data packets sent to this group, and the data packets are the relevant information for setting addressing, etc. The slave station completes the address setting according to the set addressing packet.

[0166] Method 3: Unicast distribution.

[0167] For the terminals that have formed the mapping table, the base station can separately combine the set address and logical address into a unicast for distribution according to the IP address. In this case, the resource occupation is relatively high compared to the broadcast and multicast cases.

[0168] As an example, assuming that the controller currently needs to implement sequential addressing for four terminals in the area, and there are other non-sequentially addressed terminals in the area, after the controller sends the address setting packet to the base station, the base station matches the IP address reported by the terminal with the setting address one by one, and assigns sequential addresses to them according to the order of the address setting packet and maps them to logical addresses.

[0169] After the allocation is completed, since the terminal does not manufacture the setting address issued by the controller for the time being, and there are other terminals in the area that do not need to be set, the base station compares the IP address in the mapping table with the group session and sends the device address packet issued by the master station as multicast information to achieve the terminal address setting. After completion, the return packet is unpacked and embedded with the sequential address information and logical address information and returned to the master station.

[0170] In the embodiment of the present application, the newly added service initialization enhancement module on the base station side can realize the formation of a mapping table of IP address, setting address, sequential address and logical address based on the UE address and the setting address; supplement the SIB1message information to realize the sending of the setting address; and realize the sending of the setting address of the master station to the slave station through various methods such as broadcast, multicast, and unicast; that is, on the one hand, the allocation of slave station addresses is realized through broadcast or multicast information; on the other hand, the sequential allocation of different slave station addresses is realized by maintaining the mapping table on the network side.
