All walks of life in society, such as finance, fiscal affairs, manufacturing and other industries, are increasingly dependent on the network. At the same time, the network structure is becoming more and more complex, and multi-node network topology structures are increasingly used in various scenarios.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] The embodiments of the present disclosure provide a network node access method, which can be applied to a multi-node network, and the multi-node network can be, for example, a mesh (multi-hop) network. A mesh network is a new type of wireless communication network architecture. In a mesh network, any node device can act as a router, each node device can send and receive signals, and each node device can communicate directly with one or more node devices, thereby achieving communication over a wider range.

[0044] As the number of mesh network device nodes increases, the number of packets sent and received in the entire network will gradually increase, but the bandwidth of the entire mesh network is limited. Therefore, it is necessary to control the business of each node so that the overall number of packets sent is controlled below the bandwidth.

[0045] In related technologies, new node devices are usually directly connected. However, as the number of node devices continues to increase, the business resources (such as bandwidth) allocated to each device become less and less. As a result, some node devices will be squeezed out of the network, or during data transmission, data packet loss will occur due to insufficient bandwidth, seriously affecting the stability and reliability of the network connection.

[0046] Based on this, the network node access method provided by the embodiment of the present disclosure does not directly connect to the new node device when an existing node in the network receives a new access request, but only connects to the new node device when the available business resources of the existing node can meet the required business resources of the new node device, thereby ensuring stable and efficient communication of the entire mesh network.

[0047] like Figure 1 As shown in FIG. 1 , a typical mesh network structure diagram in the prior art is shown. The new node in the embodiment of the present disclosure is Figure 1 The new node in the embodiment of the present disclosure is the other node other than the new node device. Figure 1Any one of the nodes 1 to N in .

[0048] Combination Figure 2 As shown, a network node access method provided by an embodiment of the present disclosure, the method specifically includes the following steps:

[0049] S202: Receive a network access request.

[0050] The network access request is sent by a new node device, and the network access request includes the device type and the service to be processed of the new node device.

[0051] It should be noted that the new node devices in the embodiments of the present disclosure can be divided into four types of nodes according to the binding status and historical access information, such as Figure 3a As shown, the first type of node is a node that has been connected to the network and is an intermediate node or root node of the network, but there are nodes that have not been bound in the node device and the lower-level node devices connected to the node device. Figure 3b As shown in FIG. 1 , the second type of node is a node that has been connected to the network and is an intermediate node or a root node of the network, and the node device and the lower-level node devices connected to the node device have been bound. Figure 3c As shown in , the third type of node is a new node device that has not been connected to the network and has not been bound. Figure 3d As shown, the fourth type of node is a new node device that has not been connected to the network, but the node has been bound before.

[0052] Above Figures 3a to 3d The four types of node devices in the embodiment of the present disclosure can all be the new node devices described in the embodiments of the present disclosure. Specifically, the node devices can be mobile terminals, PCs, servers, routers and other intelligent terminals. The above-mentioned binding refers to the binding of the identification information of the device in the network. The identification information can be used to uniquely identify the device, such as the device's ID, serial number, user name, etc. Binding can also be understood as registration, that is, the identification information of the device is retained in the network through registration. Bound devices do not need to be re-bound after re-accessing the network. Devices that have not been bound need to be bound when they access the network for the first time.

[0053] S204: Determine the required service resources required for accessing the network according to the device type of the new node device and the service to be processed.

[0054] Specifically, the services to be processed include services running on the new node devices, such as various APPs, data sending and receiving tasks, data transfer tasks, etc. running on the new node devices.

[0055] S206: When the available service resources of the current node meet the required service resources, establish a connection with the new node device to enable the new node device to access the network.

[0056] The available service resources of the node may be understood as the remaining service resources of the node, that is, after the available service resources are allocated, service processing of other nodes connected to the node will not be affected.

[0057] The new node device establishes a connection with the current node, which can be a direct connection or a connection confirmation before the connection, such as judging the communication signal strength or sending a connection request, so as to ensure a successful connection and avoid invalid connections.

[0058] The above-mentioned network node access method provided by the embodiment of the present disclosure obtains the required business resources of the new node access device before the new node device is accessed, and establishes a connection only when the available business resources of the current node can meet the required business resources. After the new node device is connected to the network, the business resources required for business processing can be fully guaranteed, avoiding problems such as disconnection and data loss caused by too many devices connected to a node and exceeding the available business resources of the node, thereby making network resource allocation more reasonable.

[0059] Optionally, before receiving the network access request in the above embodiment, it also includes: obtaining the service resources that have been allocated to the node; when the service resources that have been allocated to the node are less than the predetermined service resource threshold, sending a receivable signal, so that the new node device sends the network access request after receiving the receivable signal. In this way, the nodes that send the signal are all nodes with certain available service resources, avoiding the new node device from sending access requests to nodes without sufficient available service resources multiple times, saving node connection time and improving node connection efficiency.

[0060] Optionally, the receiving of the network access request includes: receiving the network access request sent by the new node device; or receiving the network access request forwarded by a lower-level node; wherein the lower-level node is in communication connection with the current node, and the available business resources of the lower-level node are less than the available business resources of the current node. In this way, when the current node cannot meet the requirements, it does not directly reject the access of the new node device, but forwards the network access request of the new node device to the node of the previous level. The node of the previous level can provide more business resources than the current node, so the available business resources of the node of the previous level are more likely to meet the required business resources. This can further ensure that the new node device successfully accesses the network, and there is no need for the new node device to find a node that can provide more business resources by itself, thereby improving the efficiency of node access.

[0061] Optionally, the required service resources include: device role bandwidth and service bandwidth.

[0062] Specifically, the device role is used to characterize the category of the device. Different devices require different bandwidth levels, and the device role level can be used to reflect the bandwidth range of the current device. For example, if the bandwidth required by a mobile terminal is less than that required by a PC or server, the device role level of the mobile terminal can be set to be lower than that of the PC or server.

[0063] The bandwidth required by various services running on the device is also different. Therefore, the required service resources also include service bandwidth.

[0064] Optionally, determining the required service resources required for accessing the network according to the device type of the new node device and the service to be processed includes: determining the device role bandwidth corresponding to the device type of the new node device based on a preset corresponding relationship; and determining the service bandwidth according to the service to be processed.

[0065] Specifically, the correspondence is the correspondence between the pre-set device role level and the bandwidth. For example, the role level can be set to include three levels, the bandwidth corresponding to the role level of the mobile terminal is 500M, the bandwidth corresponding to the role level of the PC is 800M, and the bandwidth corresponding to the role level of the server is 1G. The above correspondence can be stored on the node device or on a new node device. Of course, in order to save storage space, it can also be stored on the cloud server side. Before establishing a connection, access the server to retrieve the corresponding device role bandwidth.

[0066] Optionally, the available service resources include device role bandwidth and available service bandwidth; the situation where the available service resources of the current node meet the required service resources includes: the device role bandwidth of the current node is greater than the device role bandwidth of the new node device; and the available service bandwidth of the current node is greater than the service bandwidth of the new node device. In this way, the required service resources are divided into device role bandwidth and service bandwidth. When actually connecting, if only the role bandwidth or only the service bandwidth is considered, data transmission failure may occur after the connection is completed. Only when both the device role bandwidth and the service bandwidth are met, the established connection is more stable, further ensuring the reliability and stability of data transmission.

[0067] Optionally, the above method also includes: when the available business resources of the current node do not meet the required business resources, forwarding the network access request to a high-level node; wherein the high-level node is communicatively connected with the current node, and the available business resources of the high-level node are greater than the available business resources of the current node.

[0068] Specifically, the above-mentioned process of judging whether the available service resources meet the required service resources, and if not, forwarding the network access request to the higher-level node is a process of multiple cycles. If a higher-level node that meets the required service resources is found after one execution of judgment and forwarding, then the cycle ends. If not found, it continues to be forwarded to a higher-level node until the cycle stop condition is met. Among them, the cycle stop condition may include: the node currently receiving the forwarded network access request is a root node, or the available service resources of the node currently receiving the forwarded network access request meet the required service resources.

[0069] Combination Figure 4 As shown, another network node access method provided by an embodiment of the present disclosure is applied to an already connected node C in the network, the lower-level node of the already connected node C is node B, and the new node device is node A. The method specifically includes the following steps:

[0070] S402: Node C receives the network access request sent by node A and forwarded by node B.

[0071] S404: Node C determines the device role bandwidth corresponding to the device type of node A based on a preset corresponding relationship.

[0072] S406: Node C determines the service bandwidth of node A according to the service to be processed.

[0073] S408: Node C determines whether the device role bandwidth of the node is greater than the device role bandwidth of node A; and whether the available service bandwidth of the node is greater than the service bandwidth of node A? If yes, execute step S410; otherwise, execute step S412.

[0074] S410: Node C establishes a connection with node A.

[0075] S412: Node C forwards the network access request of node A to node D.

[0076] Node D is a higher-level node than node C. Available service resources of node D are greater than available service resources of node C.

[0077] Furthermore, node D continues to determine whether the available service resources meet the required service resources until the loop stop condition is met.

[0078] In this embodiment, when the device role bandwidth and business bandwidth can meet the needs of node A, node C connects to node A. If not, it continues to forward the request to the higher-level node D. In this way, it not only ensures that the bandwidth requirements of node A are met, but also further ensures that node A can be accessed, thereby improving the stability of new node access.

[0079] Combination Figure 5 As shown, another network node access method provided by an embodiment of the present disclosure is applied to a new node device. The method specifically includes the following steps:

[0080] S502: Send a network access request.

[0081] The network access request includes the device type of the node and the service to be processed;

[0082] S504: Receive the accessible nodes fed back by the network side.

[0083] The available service resources of the accessible node meet the required service resources of the node, and the required service resources of the node are determined according to the device type of the node and the service to be processed;

[0084] S506: Establish a connection with the accessible node and access the network.

[0085] The above-mentioned network node access method provided by the embodiment of the present disclosure first issues a network access request, receives an accessible node whose available service resources can meet the required service resources, and establishes a connection with the accessible node. Since the accessible node can meet the required service resources, the service resources required for service processing after the new node device accesses the network can be fully guaranteed, avoiding problems such as disconnection and data loss caused by too many devices connected to a node and exceeding the available service resources of the node, making the network resource allocation more reasonable.

[0086] Optionally, the accessible nodes fed back by the network side include: a node that receives the network access request; or a node that receives the network access request by forwarding a low-level node; wherein the low-level node is in communication connection with the current node, and the available service resources of the low-level node are less than the available service resources of the current node. In this way, the accessible nodes are not limited to the nodes that receive the network access request, but can also be nodes that receive the network access request forwarded by the node that receives the request, so that the new device node can obtain the accessible node by issuing a request once, without the need for the new device node to issue network access requests multiple times by itself, thereby improving access efficiency.

[0087] Optionally, when the accessible node fed back by the network side is a node that receives the network access request by forwarding through a low-level node, establishing a connection with the accessible node includes: obtaining the communication signal strength between the node device of the node and the accessible node; when the communication signal strength is greater than the signal strength threshold, sending a connection request to the accessible node; and when the connection is successful, establishing a connection with the accessible node. In this way, only nodes whose communication signal strength meets the requirements are connected, and no connection is made for nodes that only meet the required business resources but are far away or have obstacles that cause the signal to be weak, thereby ensuring the success rate of the connection and improving the data communication effect after the connection is successful.

[0088] Optionally, the method further includes: establishing a connection with a node that receives the network access request in any of the following situations: the communication signal strength is less than or equal to the signal strength threshold; and the connection with the accessible node fails.

[0089] That is, if the current node cannot establish a connection with a new node device, the new node device is not denied access to the network, but is connected to the new node device through the node that directly receives the network access request.

[0090] Optionally, before establishing a connection with the node that receives the network access request, the method further includes: reducing the required service resources of the node so that the required service resources of the node are less than the available service resources of the node that receives the network access request. In this way, the required service resources of the node are reduced before connecting, rather than directly connecting as in the prior art, which can ensure that some services after the connection can operate normally, avoid the occurrence of disconnection and packet loss, and further ensure the effectiveness and stability of the data connection.

[0091] Optionally, the required business resources include: device role bandwidth and business bandwidth, the available business resources include the device role bandwidth and available business bandwidth of the node receiving the network access request, and reducing the required business resources of this node includes: reducing the device role bandwidth of this node so that the device role bandwidth of this node is less than the device role bandwidth of the node receiving the network access request; reducing the business bandwidth of this node so that the business bandwidth of this node is less than the available business bandwidth of the node receiving the network access request.

[0092] Specifically, some services with high bandwidth requirements may be abandoned, thereby reducing the service bandwidth of the node, or services with low urgency may be abandoned, thereby reducing the service bandwidth of the node. The embodiments of the present disclosure do not limit the specific manner of reducing the service resource requirements of the node.

[0093] Optionally, after establishing the connection with the accessible node, the method further includes: determining a target application whose required business resources are lower than or equal to the available business resources of the accessible node from multiple applications installed on the node device of the node; and starting the target application.

[0094] Furthermore, for Figure 3a and Figure 3c The types of node devices shown can also enter different binding processes while running the target application or before running the target application, so that all devices running in the network are bound devices, which is convenient for subsequent device maintenance and information preservation.

[0095] Combination Figure 6 As shown, another network node access method provided by an embodiment of the present disclosure is described in detail by taking the new node device as node A, the device receiving the network access request as node B, and the high-level node of node B as node C as an example. Figure 6 As shown, the method specifically comprises the following steps:

[0096] S602: Node A sends a network access request.

[0097] S604: Node A receives the accessible nodes fed back by the network side.

[0098] S606: Node A determines that the accessible node is Node B. If yes, execute step S608; otherwise, execute step S610.

[0099] S608: Node A establishes a connection with node B, and node A accesses the network.

[0100] S610: Node A obtains the communication signal strength between itself and node C.

[0101] S612: Node A determines whether the communication signal strength is greater than the signal strength threshold, if so, executes step S614, otherwise, executes step S620.

[0102] S614: Node A sends a connection request to node C.

[0103] S616: Determine whether the connection is successful. If successful, execute step S618; otherwise, execute step S620.

[0104] S618: Node A establishes a connection with node C.

[0105] S620: Node A reduces the required service resources of the node so that the required service resources of the node are less than the available service resources of node B.

[0106] S622: Node A establishes a connection with node B.

[0107] S624: Node A determines, from a plurality of applications installed on the node device of the node, a target application whose required service resources are lower than or equal to the available service resources of the accessible node.

[0108] S626: Start the target application.

[0109] For ease of understanding, the following Figure 7 , giving examples to illustrate how new node devices and existing node devices in the network are connected in actual application scenarios. Figure 7 The new node device in the example is node A, and the existing node device is node B. In this embodiment, the device role level and service level of node B are both greater than those of node A. Figure 7 As shown, the method specifically includes:

[0110] S702: Node A sends a network access request to join the network;

[0111] S704: Node B receives the network access request;

[0112] S706: The role level and service level of node A are both lower than those of node B, and node B sends a response message to node A allowing it to join the network;

[0113] The role level may specifically refer to the bandwidth corresponding to the device role, and the service level may specifically refer to the bandwidth required by the service.

[0114] S708: Node A establishes a connection with node B, and starts an application whose role level and service level are lower than those of node B.

[0115] In this embodiment, when node B meets the needs of node A, a direct connection is established. After the connection is established, it can ensure that the original equipment connected to node B is not affected, and can also ensure that the connection of node A is stable and the application runs normally, thereby improving the stability of new node access.

[0116] Combination Figure 8 , the device role level or service level of node B in this embodiment is lower than that of node A, and the device level and service level of node C are both higher than those of node A. Figure 8 As shown, the method specifically includes:

[0117] S802: Node A sends a network access request to join the network;
