Description

Technical Field

[0002] Mesh network (wireless mesh network), also known as multi-hop network, has the characteristics of automatic fault repair, automatic networking and wider coverage, which can meet the requirements of higher-level users. Generally, the passive scanning method defined in IEEE802.11s is used to allow the receiving node to discover the Mesh network access node, so as to initiate the Mesh network device discovery connection. Among them, in the passive scanning process, the terminal periodically listens to the Mesh Beacon frames broadcast by different access points on different channels. The Mesh Beacon frame contains the parameters related to the Mesh network and the access node; after the terminal receives the Mesh Beacon, it establishes or updates the node table according to the information therein, and the terminal will initiate a Mesh connection to the access node according to the node table.

[0003] In the related art, after receiving the broadcast message from the access node to confirm the existence of the access node, the terminal needs to initiate the Mesh connection process to all surrounding access nodes in order to automatically discover topology changes and adjust the communication route to obtain the most effective transmission path, and select the appropriate data transmission path through the routing protocol after the connection is completed. When the application scenario becomes more complex, that is, there are more access nodes around the terminal (or there are multiple terminals), the network bandwidth will be occupied by the Mesh connection process, resulting in a decrease in network performance, and the device connection in the Mesh network will also be affected, making it difficult to achieve fast device connection.

[0091] The technical solutions 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.

[0092] It should be understood that the "embodiments of the present application" or "the aforementioned embodiments" mentioned throughout the specification mean that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in the embodiments of the present application" or "in the aforementioned embodiments" appearing throughout the specification may not necessarily refer to the same embodiment.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application. The above-mentioned sequence numbers of the embodiments of the present application are for description only and do not represent the advantages and disadvantages of the embodiments.

[0093] Unless otherwise specified, the electronic device performs any step in the embodiments of the present application, and the processor of the electronic device may perform the step. It is also worth noting that the embodiments of the present application do not limit the order in which the electronic device performs the following steps. In addition, the methods used to process data in different embodiments may be the same method or different methods. It should also be noted that any step in the embodiments of the present application can be independently executed by the electronic device, that is, when the electronic device executes any step in the following embodiments, it may not rely on the execution of other steps.

[0094] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0095] The present application embodiment provides a connection establishment method, which can be applied to a terminal, referring to Figure 1 As shown, the method comprises the following steps:

[0096] Step 101: When it is determined that there are terminals and access nodes in the Mesh network, access resource configuration information sent by the access node is received.

[0097] The access resource configuration information carries a configuration identifier.

[0098] In an embodiment of the present application, it is necessary to first determine whether there are terminals and access nodes that need to be connected in the Mesh network; when it is determined that there are terminals and access nodes that need to be connected in the Mesh network, the access node can broadcast the access resource configuration information in a broadcast message to the terminals in the Mesh network; wherein, multiple access nodes in the Mesh network can simultaneously broadcast their respective access resource configuration information to the terminals.

[0099] It should be noted that the configuration identifier can be used to uniquely identify the access resource configuration information of each access node. In a feasible implementation, the access resource configuration information may refer to Mesh access resource configuration information, which may include at least node information of each node and connection configuration information required for connection.

[0100] In other embodiments of the present application, the Mesh network architecture can be as follows: Figure 2 As shown in the figure, the Mesh network can include access nodes and root nodes, and each node can be connected to other nodes, and two nodes can communicate directly; at the same time, each node in the Mesh network can send and receive signals; the root node (also called the Mesh Portal Point (MPP)) is a node that connects the Mesh network to other types of networks, realizing the communication connection between the Mesh network and the external network. It should be noted that Figure 2 As shown in the figure, the solid lines in the Mesh network represent the links between access nodes, and the dotted lines represent the links between nodes and terminals. In a feasible implementation, the access node may refer to a Mesh Access Point (MAP), which can be connected to other nodes for direct communication, and each node in the network can send and receive signals (i.e., provide access services); the terminal may refer to a User Equipment (UE), i.e., a User Station (STA).

[0101] Step 102: Determine first node information of an access node corresponding to the configuration identifier based on the access resource configuration information.

[0102] The first node information represents the attribute information and capability information of the access node.

[0103] In an embodiment of the present application, the terminal can parse the received Mesh access resource configuration information, and then obtain the first node information of the access node. The first node information may include attribute parameters and access layer capability parameters of the access node; in a feasible implementation, the first node information may include the device type of the access node, the physical location information of the access node, and the access layer capability information of the access node; specifically, the access layer capability information may include: data transmission rate, carrying capacity, supported data type and other parameters.

[0104] Step 103: Filter and obtain target access nodes whose first node information meets the target filtering condition.

[0105] In an embodiment of the present application, target filtering conditions can be configured on terminals and access nodes in a Mesh network; and the target filtering conditions are configured by the application layer, basic service layer, or Mesh-related functional unit module / layer of the terminal and the access node; specifically, the application layer, basic service layer, or Mesh-related functional unit module / layer of the terminal configures the target filtering conditions on the terminal; the application layer, basic service layer, or Mesh-related functional unit module / layer of the access node configures the target filtering conditions for the access node.

[0106] In addition, the terminal can filter out target access nodes whose first node information meets the target filtering conditions from all access nodes based on the first node information; that is, the terminal can filter out target access nodes whose physical location information meets the target physical location information, whose device type meets the target device type, and whose capability information meets the target access layer capability information from all access nodes.

[0107] Step 104: Establish a communication connection with the target access node based on the access resource configuration information.

[0108] In an embodiment of the present application, after screening out the target access node, the terminal can initiate a connection request to the target access node based on the Mesh access resource configuration information, and then after receiving a confirmation message of the connection application replied by the target access node, it can be considered that the terminal has successfully established a communication connection with the target access node.

[0109] Wherein, step 104 can be implemented by the following methods:

[0110] Step 104a: Create a node table for the target access node.

[0111] In an embodiment of the present application, the terminal may establish a node table, and set all the screened target access nodes in the node table.

[0112] Step 104b: Determine the device priority of the access node from the access resource configuration information.

[0113] The terminal can parse the Mesh access resource configuration information to obtain the device priority of the access node.

[0114] Step 104c: Establish a communication connection with the target access node in the node table according to the device priority.

[0115] Among them, the terminal can determine the device priority of the target access node in the node table from the device priority of the access node; then, according to the device priority of the target access node, communication connections can be established with the target access nodes in the node table starting from the highest device priority.

[0116] It should be noted that the connection establishment method in the embodiment of the present application can be to add Mesh access resource configuration information and target filtering conditions in the passive scanning process defined based on IEEE802.11s, so that the terminal can judge and only send connection applications to target access nodes that meet the requirements, which greatly reduces the amount of signaling within the Mesh network and improves the efficiency of device connection discovery.

[0117] The connection establishment method provided in the embodiment of the present application can screen the access nodes according to the node information of the access nodes in the access resource configuration information, and only establish a communication connection with the screened target access nodes based on the access resource configuration information, rather than establishing a communication connection with all access nodes, thereby solving the problem in the related technology that the network bandwidth of the device connection establishment scheme of the Mesh network is occupied by the Mesh connection process, resulting in a decrease in network performance, and realizes the rapid establishment of device connections in the Mesh network.

[0118] Based on the above embodiments, the present application provides a connection establishment method, which can be applied to an access node. Figure 3 As shown, the method may include the following steps:

[0119] Step 201: When it is determined that there are a terminal and an access node in the Mesh network, obtain second node information of the terminal.

[0120] The second node information represents the attribute information and capability information of the terminal.

[0121] In an embodiment of the present application, after determining that there are terminals and access nodes that need to establish a connection in the Mesh network, the access node can obtain the second node information of the terminal from the Mesh network. The second node information may include attribute parameters and access layer capability parameters of the terminal; in a feasible implementation, the second node information may include the device type of the terminal, the physical location information of the terminal, and the access layer capability information of the terminal; specifically, the access layer capability information may include: data transmission rate, carrying capacity, supported data type and other parameters.

[0122] It should be noted that the operation of obtaining the second node information of the terminal can be performed after the access node receives the connection request sent by the terminal (that is, the terminal side has screened the access node), or it can be performed at the very beginning (that is, before any operation is performed).

[0123] Step 202: Filter and obtain target terminals whose second node information meets the target filtering condition.

[0124] In an embodiment of the present application, the access node can filter, based on the second node information, target terminals whose second node information meets the target filtering conditions from all terminals; that is, target terminals whose physical location information meets the target physical location information, whose device type meets the target device type, and whose capability information meets the target access layer capability information can be filtered from all terminals.

[0125] Step 203: Establish a communication connection with the target terminal based on the access resource configuration information.

[0126] In an embodiment of the present application, the access node may send access resource configuration information to the target terminal, and after receiving the connection request sent by the target terminal, the access node may reply with a confirmation message of the connection application, and it may be considered that the target terminal and the access node have successfully established a communication connection. Alternatively, after receiving the connection request sent by the terminal, the target terminal selected may be replied with a confirmation message of the connection application based on the Mesh access resource configuration information, and it may be considered that the target terminal and the access node have successfully established a communication connection.

[0127] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.

[0128] The connection establishment method provided in the embodiment of the present application can screen the terminals according to the acquired node information of the terminals, and establish communication connections only with the screened target terminals based on the access resource configuration information, rather than establishing communication connections with all terminals, thereby solving the problem in the related art that the network bandwidth of the device connection establishment scheme of the Mesh network is occupied by the Mesh connection process, resulting in a decrease in network performance, and realizes the rapid establishment of device connections in the Mesh network.

[0129] Based on the above embodiments, the present application provides a connection establishment method. Figure 4 As shown, the method may include the following steps:

[0130] Step 301: When it is determined that there are terminals and access nodes in the Mesh network, the terminal receives access resource configuration information sent by the access node.

[0131] The access resource configuration information carries a configuration identifier.

[0132] In an embodiment of the present application, the access resource configuration information includes at least one of the following information:

[0133] An identifier for accessing resource configuration information;

[0134] The requested offset corresponding to the terminal;

[0135] The maximum length of the request corresponding to the terminal;

[0136] The offset of the request response corresponding to the terminal;

[0137] The request type indication corresponding to the terminal;

[0138] The request corresponding to the terminal may carry information indication;

[0139] Configuration priority of access resource configuration information;

[0140] Device priority of access node;

[0141] The device type of the access node;

[0142] Physical location information of access nodes;

[0143] Capability information of the access node.

[0144] Among them, the identifier of the access resource configuration information is used to indicate the identity of the Mesh access resource configuration information. Different Mesh access resource configuration information should maintain a unique identity in the Mesh network; the request offset corresponding to the terminal is used to indicate the address of the connection application signaling initiated by the terminal, so that the access node can quickly find the relevant data information according to the request offset, and the implementation method can be a number; the maximum length of the request corresponding to the terminal is used to indicate the data length of the connection application signaling initiated by the terminal, and the implementation method can be a number; the offset of the request response corresponding to the terminal is used to indicate the sending address of the access node request response, and the implementation method can be a number; the request type indication corresponding to the terminal is used to indicate the type of connection application sent by the terminal and mark the purpose of the connection application. The implementation method can be a number or a string and other methods; the request corresponding to the terminal can carry information indication to indicate the information content allowed to be carried in the subsequent request sent by the terminal; the configuration priority of the access resource configuration information indicates the priority of the processing and parsing of the Mesh access resource configuration information (the priority of the Mesh access resource configuration information itself), the access resource When configuring messages, they are executed in order from high to low according to this priority; the device priority of the access node is used to indicate the connection priority of the access node in the Mesh network. The terminal initiates a connection with the access node according to the priority from high to low to achieve fast device selection. The implementation method of this information can be a number, a string, or other methods. For example, if a number is used, the smaller the number, the higher the priority. "00" represents a high priority, and "01" represents a medium priority. If a string is used, "high" represents a high priority, and "medium" represents a medium priority. The device type of the access node is used for the terminal to know the device type of the access node according to this information, such as communication equipment, lighting equipment, imaging equipment, printing equipment, etc. The implementation method of this information can be a number, a string, or other methods. For example, if a number is used, "000" represents a communication device, "001" represents a lighting device, and if a string is used, "communication" represents a communication device, and "lighting" represents a lighting device. The physical location information of the access node is used to indicate the physical location information of the access node that sends the configuration information. The implementation method can be a tracking area (Tracking area). Area, TA), numbers (indicating the straight-line distance from the broadcast node to the receiving node), etc.; the access node capability information is used to indicate the access layer capabilities of the access node, including data transmission rate, carrying capacity, supported data types, etc.

[0145] It should be noted that Figure 4 The figure takes a Mesh network with three access nodes (i.e., access node 1, access node 2, and access node 3) as an example for illustration; that is, each access node (i.e., access node 1, access node 2, and access node 3) can send Mesh access resource configuration information to the terminals in the Mesh network by broadcasting.

[0146] Step 302: The terminal determines first node information of an access node corresponding to the configuration identifier based on the access resource configuration information.

[0147] The first node information represents the attribute information and capability information of the access node.

[0148] In an embodiment of the present application, if the access nodes include access node 1, access node 2 and access node 3, then the terminal can parse the Mesh access resource configuration information sent by each access node (i.e., access node 1, access node 2 and access node 3) respectively, thereby obtaining the first node information of each access node (i.e., access node 1, access node 2 and access node 3) corresponding to the configuration identifier.

[0149] Step 303: The terminal screens and obtains a target access node whose first node information satisfies a target filtering condition.

[0150] In the embodiment of the present application, the terminal can filter out a target access node that meets the target filtering condition from access node 1, access node 2, and access node 3; in a feasible implementation, Figure 4 In the figure, the screened target access node is taken as access node 1 as an example. That is to say, the subsequent terminal can establish a communication connection with access node 1.

[0151] In the embodiment of the present application, the target filtering condition includes at least one of the following information:

[0152] Target device type;

[0153] Target physical location information;

[0154] Target access layer capability information.

[0155] Among them, the target device type indicates the screening condition of the device type. Nodes that do not match the data will not establish a connection. The implementation method of this information can be a number, a string, and other methods. For example, when the number method is used, "000" represents that the communication device meets the conditions, "001" represents the lighting device conditions, and when the string method is used, "communication" represents that the communication device meets the conditions, and "lighting" represents that the lighting device meets the conditions; the target physical location information indicates the screening condition of the physical location. Nodes that are not within the range indicated by the physical location information will not establish a connection. Its implementation method can be: TA, a number (indicating the straight-line distance from the broadcast node to the receiving node). When the implementation method is a number, the physical location information carried by the node exceeds the filtering condition and the connection will not be established; the target access layer capability information is used to filter the access layer capability information including data transmission rate, carrying capacity, supported data type, etc. In a feasible implementation method, when the user wants to select a smart light bulb within 5m of the system through a mobile phone, the target filtering condition of the terminal can be configured as the device type is "lighting" and the physical location information is "5".

[0156] Step 304: The terminal establishes a node table for the target access node.

[0157] Step 305: The terminal determines the device priority of the access node from the access resource configuration information.

[0158] Step 306: The terminal obtains connection configuration information from the access resource configuration information.

[0159] Step 307: The terminal sends a connection request carrying connection configuration information to a target access node in the node table according to the device priority.

[0160] The connection configuration information may be obtained by parsing the Mesh access resource configuration information; and the connection configuration information may refer to the configuration information required for connection access. In a feasible implementation, the connection configuration information may include at least one of the following information: the request offset corresponding to the terminal, the maximum length of the request corresponding to the terminal, the offset of the request response corresponding to the terminal, the request type indication corresponding to the terminal, and the request carryable information indication corresponding to the terminal. If there are multiple selected target access nodes, the terminal can periodically carry the connection configuration information in the connection request and send it to the target access node in turn according to the device priority of each target access node from high to low.

[0161] It should be noted that the access nodes include the screened target access nodes.

[0162] Among them, Figure 4 After step 307, you can choose to perform steps 308 to 310, or, Figure 5Execute steps 311 to 314 as shown.

[0163] Step 308: The target access node receives the connection request sent by the terminal.

[0164] Step 309: The target access node sends a successful response message for the connection request.

[0165] Step 310: The terminal receives the success response information sent by the target access node to establish a communication connection with the target access node.

[0166] In other embodiments of the present application, if the target access node believes that a communication connection can be established with the terminal at present, the target access node will send a success response message to the terminal, so that the terminal and the target access node successfully establish a communication connection; if the target access node believes that a communication connection cannot be established with the terminal at present, the target access node will send a failure response message to the terminal, thereby informing the target access node not to establish a communication connection with the terminal; and the failure response message may carry a description of the reason for the failure, such as: failure to meet the filtering conditions, limited resources on the local side, Mesh node access failure, etc.

[0167] Step 311: The target access node receives a connection request sent by a terminal, and obtains second node information of the terminal based on the connection request.

[0168] The connection request carries the connection configuration information in the access resource configuration information.

[0169] Step 312: The target access node screens and obtains a target terminal whose second node information meets a target filtering condition.

[0170] Step 313: The target access node sends a success response message to the target terminal based on the connection request and the connection configuration information to establish a communication connection with the target terminal.

[0171] Step 314: The target terminal receives the success response information sent by the target access node.

[0172] It should be noted that Figure 5 The corresponding embodiment (i.e., steps 311 to 314) may be that after the terminal screens the access nodes to obtain the target access node, and the target access node sends a connection request, the target access node may further screen the terminal to obtain the target terminal; further, the target access node will only reply with a successful response message to the connection request sent by the target terminal, so that the target terminal and the target access node can successfully establish a communication connection. It should be noted that the terminal includes the screened target terminal.

[0173] In other embodiments of the present application, Figure 6As shown, the following steps may be included before step 301:

[0174] Step 315: When it is determined that there are a terminal and an access node in the Mesh network, the access node obtains the second node information of the terminal.

[0175] The second node information represents the attribute information and capability information of the terminal.

[0176] Step 316: The access node screens and obtains a target terminal whose second node information meets the target filtering condition.

[0177] Step 317: The access node sends access resource configuration information to the target terminal via a broadcast message.

[0178] In the embodiments of the present application, Figure 6 As shown, the access node will not be screened, but before the connection is initiated, the access node screens multiple existing terminals to obtain the target terminal, and then sends the Mesh access resource configuration information to the screened target terminal by broadcasting, so as to establish a communication connection with the target terminal.

[0179] It should be noted that in step 301, the target terminal in the terminal receives the access resource configuration information sent by the access node. Figure 6 As shown, the following steps can be performed after step 301:

[0180] Step 318: The target terminal sends a connection request carrying connection configuration information to the access node.

[0181] The connection configuration information is determined by the target terminal based on the access resource configuration information.

[0182] Step 319: The access node receives a connection request carrying connection configuration information sent by the target terminal.

[0183] Step 320: The access node sends a success response message to the target terminal based on the connection request and the connection configuration information to establish a communication connection with the target terminal.

[0184] In the embodiments of the present application, by screening terminals, or screening access nodes, or screening both terminals and access nodes, it is possible to effectively solve the problem that when there are many devices in the Mesh network, signaling congestion is caused when the terminal connects to other Mesh network devices, affecting the Mesh network rate or even causing the Mesh network to crash; and, it is possible to adapt to different scenarios in which terminals and access nodes in the Mesh network selectively send signaling messages to specific nodes according to target filtering conditions and their own capability requirements, thereby better ensuring the normal interaction of devices in the Mesh network.
