[0002] In the field of mobile cellular IoT communication, IoT platforms provide unified management of IoT devices and data collection functions. IoT devices connect to the IoT platform's server cluster via the mobile communication network and then through the backbone network.

[0003] Currently, with the increasing number of IoT devices, the business processing pressure on IoT platforms is gradually increasing, necessitating the addition of IP addresses to expand server clusters for load balancing. However, IoT devices are widely distributed and numerous, so migrating their data to new server clusters by reconfiguring their destination IP addresses on-site or remotely modifying them would incur significant manpower and time costs.

[0015] The user identifier is obtained by querying the first relationship mapping table based on the device identifier;

[0016] The virtual private channel for transmitting the data is determined by querying the second relational mapping table based on the user identifier.

[0017] The data is sent through the virtual private channel.

[0018] According to some embodiments of the present invention, the server cluster is used for:

[0019] Receive the data from the virtual private channel;

[0020] Parse the second IP address in the data;

[0021] The destination server is determined based on the second IP address.

[0022] According to some embodiments of the present invention, the gateway platform further includes a configuration module, the configuration module being used for:

[0023] Get configuration commands;

[0024] In response to the configuration instruction, the user identifier and server cluster number are obtained by parsing the configuration instruction;

[0025] The virtual private channel is determined based on the server cluster code;

[0026] A second relationship mapping table is formed by binding the virtual private channel with the user identifier in the configuration instruction.

[0027] On the other hand, embodiments of the present invention also provide a method for migrating data of IoT devices, which is applied to the gateway platform of the IoT device data migration system as described above;

[0028] The IoT device data migration method includes the following steps:

[0029] Receive data from IoT devices;

[0030] The user identifier of the IoT device is determined based on the data;

[0031] A virtual private channel for transmitting the data is determined based on the user identifier;

[0032] The data is sent through the virtual private channel.

[0033] According to some embodiments of the present invention, the IoT device data migration method further includes the following steps:

[0034] Obtain the device identifier of the IoT device;

[0035] A user identifier and a first IP address are generated for the IoT device based on the device identifier;

[0036] Send the first IP address to the IoT device;

[0037] The device identifier and the user identifier are bound to form a first relationship mapping table.

[0038] According to some embodiments of the present invention, determining the user identifier of the Internet of Things device based on the data includes the following steps:

[0039] The device identifier of the IoT device is obtained by parsing the data;

[0048] The technical solution described above has at least one of the following advantages or beneficial effects: When an IoT device transmits data to the server cluster of an IoT platform, the gateway platform first receives the data from the IoT device and determines the user identifier of the IoT device pre-installed in the gateway platform based on the data. A virtual private channel (VPN) for data transmission is then determined based on the user identifier. Since each VPN corresponds to a server cluster, the data of the IoT device can be migrated to the corresponding server cluster after the VPN is determined. By establishing a VPN between the gateway platform and each server cluster of the IoT platform, instead of addressing and forwarding based on the IP address in the data, the gateway platform determines the VPN based on the user identifier of the IoT device, thereby enabling data to be sent to the server cluster corresponding to the VPN. Therefore, only the user identifier pre-installed in the gateway platform needs to be changed to achieve data migration for the IoT device, without needing to change the configuration of the IoT device, thus saving data migration costs.

[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar originals or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0056] In the description of this invention, the use of terms such as "first," "second," etc., is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0057] Before providing a further detailed description of the embodiments of this application, the nouns and terms involved in the embodiments of this application will be explained, and the nouns and terms involved in the embodiments of this application shall be interpreted as follows.

[0058] HSS (Home Subscriber Server) is a crucial component of the control layer in IMS (IP Multimedia Subsystem). HSS supports the main user database for IMS network entities that handle calls / sessions. It contains user profiles, performs user authentication and authorization, and provides information about user physical locations. It is similar to GSM HomeLocationRegister. The entities that communicate with HSS are the application server and the call session control function server.

[0059] The MME (Mobility Management Entity) is a key control node in the 3GPP LTE access network. It is responsible for the location of UEs (User Equipment) in idle mode, paging processes, including relaying; simply put, the MME is responsible for signaling processing. It is involved in the bearer activation / deactivation process and selects an SGW (Serving Gateway) for a UE when it initializes and connects. It authenticates a user by interacting with the HSS and assigns a temporary ID to the user.

[0060] The Serving Gateway (SGW) is a crucial network element in the core mobile communication network. In traditional networks, the Serving GPRS Support Node (SGSN) is responsible for both signaling plane functions such as mobility management and user access control, as well as user data forwarding. Based on the principle of separating control and bearer functions, the functions of the SGSN are split in the core mobile communication network: signaling plane functions are handled by the MME (Mobile Equipment Manager) network element, while user plane functions such as user data forwarding are taken over by the SGW network element.

[0061] A PGW (PDN Gateway) is a boundary gateway for the mobile communication core network, providing functions such as user session management and bearer control, data forwarding, IP address allocation, and access for non-3GPP users. It serves as the anchor point for the PDN (Public Data Network) in both 3GPP and non-3GPP access networks. 3GPP access refers to radio access technologies from the 3GPP standards family, while non-3GPP access refers to radio access technologies outside the 3GPP standards family.

[0062] CE (Customer Edge) is the user-end router to which the service provider connects. The CE router provides service access to users by connecting to one or more PE routers.

[0063] VPN (Virtual Private Network) is a remote access technology that uses data encapsulation and encryption to establish a private network over a public network, thus creating a virtual private tunnel on the public network. A VPN gateway enables remote access by encrypting data packets and translating their destination addresses. VPNs can be implemented through various methods, including servers, hardware, and software.

[0064] Each server cluster on the IoT platform provides a public IP address to the outside world, while using internal IP addresses within the server cluster. The traditional method for IoT devices to send data to the IoT platform is as follows: the IoT device is configured with the destination server's IP address; the IoT device encapsulates data packets based on the destination IP address and sends the packets to the gateway platform for forwarding; the gateway platform forwards the data to the corresponding server cluster based on IP address addressing; and the server cluster then forwards the data to the destination server within the server cluster based on the destination IP address in the data. Because data forwarding uses IP address addressing at the gateway platform, the internal IP addresses within different server clusters cannot be the same, otherwise routing conflicts will occur. To migrate data from an IoT device to another server cluster, the destination IP address configured in the IoT device must be changed.

[0065] Based on this, embodiments of the present invention provide an IoT device data migration system, referring to... Figure 1 The IoT device data migration system includes a gateway platform and an IoT platform, where the IoT platform comprises multiple server clusters. A virtual private channel (VPN) is established between the gateway platform and each server cluster of the IoT platform for communication.

[0066] The gateway platform is used to receive data from IoT devices, determine the user identifier of the IoT devices based on the data, determine the virtual private channel for data transmission based on the user identifier, and send data through the virtual private channel. The user identifier is pre-set in the gateway platform.

[0067] Specifically, with Figure 1 Taking the IoT device data migration system shown as an example, the system includes a gateway platform and an IoT platform. The IoT platform includes server cluster 1 and server cluster 2. Based on VPN technology, a virtual private channel (VPN1) is established between the gateway platform and server cluster 1, and a similar VPN2 is established between the gateway platform and server cluster 2. IoT devices 1, 2, 3, and 4 are connected to the gateway platform. When the gateway platform receives data from any IoT device, it determines the user identifier pre-installed in the gateway platform for that IoT device based on the received data, and then determines the VPN2 used to transmit the data. For example, the VPN2 corresponds to user identifier "1" and the VPN3 corresponds to user identifier "2". Devices 1 and 2 have user identifiers of "1" in the gateway platform, while devices 3 and 4 have user identifiers of "2". Therefore, data from devices 1 and 2 is transmitted to server cluster 1 via VPN1, and data from devices 3 and 4 is transmitted to server cluster 2 via VPN2. Because different Virtual Private Channels (VPNs) are established between the gateway platform and different server clusters, these VPNs can create network barriers and avoid routing conflicts. Therefore, the destination IP address of data transmitted in different VPNs can be the same. For example, device 1 and device 3 may be configured with the same destination IP address, but because device 1 and device 3 have different user identifiers pre-configured in the gateway platform, they can be addressed in different server clusters through different VPNs. If it is necessary to migrate data from device 1 to server cluster 2, simply changing the user identifier of device 1 in the gateway platform to "2" will allow the data from device 1 to be transmitted to server cluster 2 via VPN 2, without needing to change the destination IP address configured in device 1.

[0068] According to some specific embodiments of the present invention, referring to Figure 2The gateway platform includes a device access authentication module, which is used for:

[0069] Obtain the device identifier of the IoT device;

[0070] Generate a user identifier and a first IP address for the IoT device based on the device identifier;

[0071] Send the first IP address to the IoT device;

[0072] The binding device identifier and user identifier form the first relationship mapping table.

[0073] Specifically, the IoT device initiates a network access authentication module to access the network. The module uses the IoT device's MAC address as the device identifier and assigns a CC (Charging Characteristic) value as the user identifier to the MAC address. Then, it binds the MAC address and the CC value to form a first relationship mapping table. Furthermore, after the IoT device initiates the authentication request, the module assigns a first IP address as the source IP address and sends the assigned first IP address to the IoT device. The IoT device's network access request is then successful.

[0074] According to some embodiments of the present invention, with reference to Figure 2 The gateway platform also includes a data packet forwarding module, which is used for:

[0075] Parse the data to obtain the device identifier of the IoT device;

[0076] The user identifier is obtained by querying the first relational mapping table based on the device identifier;

[0077] The virtual private channel used for data transmission is determined by querying the second relational mapping table based on the user identifier;

[0078] Data is sent via a virtual private channel.

[0079] Specifically, the IoT device sends data to the server cluster in the IoT platform through the gateway, using the first IP address as the source IP address. The data packet forwarding module in the gateway platform parses the data from the IoT device to obtain the MAC address of the IoT device. Based on the MAC address, it queries the first relational mapping table in the device access authentication module to obtain the corresponding CC value. Then, based on the CC value, it queries the second relational mapping table to determine the corresponding virtual private channel, and finally sends the data to the corresponding server cluster through the virtual private channel.

[0080] According to some specific embodiments of the present invention, the server cluster is used for:

[0081] Receive data from the virtual private channel;

[0082] The second IP address is parsed from the data;

[0083] The destination server is determined based on the second IP address.

[0084] Specifically, the server cluster is equipped with firewall devices. These firewall devices decrypt and identify data packets, accepting only data from the corresponding virtual private channel (VPN) and isolating data from other VPNs. The server cluster then parses the second IP address in the data, which is the destination IP address. Based on this second IP address, the data is determined and forwarded to the destination server or the next-level destination server cluster.

[0085] According to some specific embodiments of the present invention, the gateway platform further includes a configuration module, which is used for:

[0086] Get configuration commands;

[0087] In response to configuration commands, parse the user identifier and server cluster number contained in the configuration commands;

[0088] The virtual private channel is determined based on the server cluster code;

[0089] A second relationship mapping table is formed by binding the virtual private channel and the user identifier in the configuration command.

[0090] Specifically, the configuration module obtains configuration instructions input by the user, which include a user identifier and a server cluster number. In response to the configuration instructions, the module parses them to obtain the user identifier and server cluster number, then determines the corresponding Virtual Private Channel (VPN) based on the server cluster number. A second relationship mapping table is formed by binding the VPN with the user identifier in the configuration instructions, enabling batch migration of IoT device data. In this embodiment, the configuration instructions can change the correspondence between user identifiers and VPNs in the gateway platform. For example, changing the VPN corresponding to user identifier "2" to VPN1 can enable batch migration of data from all IoT devices with user identifier "2" to server cluster 1.

[0091] In other embodiments, the configuration instructions input by the user may also include a user identifier and a device identifier. In the configuration module, in response to the configuration instructions, the user identifier and device identifier are parsed, and the user identifier and device identifier in the configuration instructions are bound to form a second relationship mapping table, enabling data migration for a specific IoT device. In this embodiment, the configuration instructions can change the correspondence between user identifiers and device identifiers in the gateway platform. For example, changing the user identifier corresponding to device identifier "MAC1" from "1" to "2" can migrate the data of the IoT device with device identifier "MAC1" from server cluster 1 to server cluster 2.

[0092] This invention provides a method for migrating data from Internet of Things (IoT) devices, applied to the gateway platform of the network device data migration system described in the above embodiments. (Refer to...) Figure 3 The IoT device data migration method of this invention includes, but is not limited to, steps S110, S120, S130 and S140.

[0093] Step S110: Receive data from IoT devices;

[0094] Step S120: Determine the user identifier of the IoT device based on the data, wherein the user identifier is pre-set in the gateway platform;

[0095] Step S130: Determine the virtual private channel used for data transmission based on the user identifier;

[0096] Step S140: Send the data through a virtual private channel.

[0097] In this embodiment, the gateway platform receives data from IoT devices and determines the user identifier of the IoT device pre-installed in the gateway platform based on the data. Based on the user identifier, a virtual private channel (VPN) is determined for data transmission. Since each VPN corresponds to a server cluster, the data of the IoT device can be migrated to the corresponding server cluster after the VPN is determined. By establishing VPNs between the gateway platform and each server cluster of the IoT platform, instead of forwarding data based on the IP address in the data, the gateway platform determines the VPN based on the user identifier of the IoT device, thus enabling data to be sent to the server cluster corresponding to the VPN. Therefore, only the user identifier pre-installed in the gateway platform needs to be changed to achieve data migration for the IoT device, without needing to change the configuration of the IoT device, saving data migration costs.

[0098] According to some specific embodiments of the present invention, the IoT device data migration method of the present invention further includes, but is not limited to, the following steps:

[0099] Obtain the device identifier of the IoT device;

[0100] Generate a user identifier and a first IP address for the IoT device based on the device identifier;

[0101] Send the first IP address to the IoT device;

[0102] The binding device identifier and user identifier form the first relationship mapping table.

[0103] In this embodiment, network access attachment can be implemented for IoT devices. Network access attachment includes assigning a first IP address to the IoT device, which is the source IP address in the data packets uploaded by the IoT device. Network access attachment also includes pre-setting a user identifier for the IoT device.

[0104] According to some specific embodiments of the present invention, step S120 includes, but is not limited to, the following steps:

[0105] Parse the data to obtain the device identifier of the IoT device;

[0106] The user identifier is obtained by querying the first relational mapping table based on the device identifier;

[0107] Step S130 includes, but is not limited to, the following steps:

[0108] The virtual private channel used for data transmission is determined by querying the second relational mapping table based on the user identifier.

[0109] In this embodiment, based on the device identifier in the data of the IoT device, the virtual private channel used to transmit the data is determined by querying the first relation mapping table and the second relation mapping table, so as to send the data to the corresponding server cluster through the corresponding virtual private channel.

[0110] The following reference Figure 4 Taking the gateway platform as the 4G core network and the user identifier as the CC value as an example, this paper illustrates the IoT device data migration method of this embodiment.

[0111] The 4G core network includes MME, HSS, SGW, PGW, and CE network elements. When a user's IoT device initiates a network access request to the MME, the MME forwards the request to the HSS. The HSS obtains a CC value from the receiving end and returns it to the MME. The MME then sends the IoT device's device identifier and CC value to the SGW for storage. When the IoT device uploads data to the IoT platform's server cluster, the SGW maps the IoT device's data to obtain the user identifier, and the PGW determines the Virtual Private Channel (VPN) based on the user identifier. The CE uses Network Address Translation (NAT) technology to send the data into the corresponding VPN, thus delivering it to the relevant server cluster. The server cluster's firewall receives the data from the corresponding VPN.
