Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of devices and apparatus consistent with certain aspects of the invention, as detailed in the appended claims.

In order to facilitate understanding of those skilled in the art, the embodiments of the present disclosure set forth a plurality of implementations for clearly illustrating the technical solutions of the embodiments of the present disclosure. Of course, it can be understood by those skilled in the art that the embodiments provided in the present disclosure can be implemented alone, or in combination with other embodiments of the methods in the present disclosure, or in combination with some methods in other related technologies; the disclosed embodiments are not limited thereto.

To facilitate an understanding of any embodiment of the present disclosure, a Mesh network is first described.

A Mesh network is a type of wireless local area network, i.e. a Mesh network, also called a "multi-hop" network. The Mesh network is composed of routers (Mesh routers) and clients (Mesh clients), wherein the clients refer to electronic devices which can be connected with the network, such as mobile phones, computers, game machines, smart homes and the like. The node in the present disclosure refers to a router in a Mesh network. One router (called a root node) in each Mesh network is accessed to the internet in a wired mode, other routers (called child nodes) are accessed to the internet through the root node, and all the routers can be used for providing network routing services for clients.

As shown in fig. 1, the Mesh network includes 4 nodes; the node may be an Access Point (AP). The 4 access points are respectively AP1, AP2, AP3 and AP4; wherein, AP1 is a root access point, and AP2, AP3 and AP4 are sub-access points; the AP1 is connected with an external network; the AP2 is connected with the AP1 through a wire; the AP3 is connected to the AP1 by wireless. If AP4 wants to access the Mesh network, the decision is needed to select one AP from AP1, AP2 and AP3 as the AP to access. The accessed AP may be an uplink AP of the AP 4.

As shown in fig. 2, an embodiment of the present disclosure provides a flowchart of a method for accessing a Mesh network, where as shown in fig. 2, the method includes the following steps:

step S11: acquiring a first network exit rate of at least one second node; wherein the first network egress rate is a network transmission rate between the second node and the root node;

step S12: acquiring the inter-device rate of the second node; wherein the inter-device rate is a network transmission rate between the first node and the second node;

step S13: determining a second network exit rate when the first node is connected with the second node according to the first network exit rate and the inter-device rate; wherein the second network egress rate is a network transmission rate between the first node and the root node;

step S14: and selecting the second node with the second network exit rate meeting the preset rate condition from at least one second node for connection.

The method for accessing the Mesh network, which is disclosed by the embodiment of the disclosure, is executed by a first node; the first node and the second node may be any nodes in the network. The network here may be any one; for example, it may be a wireless network, a wired network, or a hybrid network. Wherein a hybrid network may refer to a network that includes one or more operator network devices and hardware; alternatively, a hybrid network may also refer to a network that includes both wirelessly connected and wired devices.

In one embodiment, the first node and the second node may be both routers or Access Points (APs) or the like. For example, the first node and the second node may both be Mesh routers of a Mesh network. Of course, in its embodiment, the first node and the second node may also be other access devices, and the first node and the second node only need to be satisfied with being able to access the terminal to the network, and no limitation is made to the types of the first node and the second node.

Here, the first node and the second node may each be connected to at least one terminal. For example, the terminal may be, but is not limited to, a computer, a mobile phone, a server, a tablet, a wearable device, a vehicle terminal, a smart home terminal, and/or a medical device, etc.

Here, the egress rate of the network port may be a network transmission rate from any node in the network to the root node. For example, the first network egress rate of the second node refers to a network transmission rate between the first node and the root node; for another example, the second network egress rate of the first node refers to a network transmission rate between the second node and the root node.

In one embodiment, the root node is a network egress device. For example, as shown in fig. 1, AP1 is a portal egress device of the network.

The inter-device rate here may be a node-to-node network transmission rate. For example, the inter-device rate between the first node and the second node refers to a network transmission rate between the first node and the second node.

In one embodiment, the portal exit rate and the inter-device rate may be: the rate of data transmission. For example, as shown in fig. 1, the network egress rate of AP2 refers to: the rate at which data is transmitted between AP1 and AP 2; for another example, the inter-device rate of AP4 and AP3 refers to: the rate at which data is transmitted between AP4 and AP 3.

In one embodiment, the first node may be an AP to be accessed; the second node may be a candidate AP accessed by the first node; the second node may be an uplink AP of the first node.

In one embodiment, the first node is a first access node to the network. For example, in the Mesh networking shown in fig. 1, the AP4 wants to access the Mesh networking; AP4 may be a first node and AP2 and AP3 may be second nodes.

In another embodiment, the first node may also be a node that has access to the network. For example, in the Mesh networking shown in fig. 1, AP3 has established a wireless connection with AP1; the AP3 may also change the topological connection in the network and re-find an AP (e.g., AP 2) to connect. In this case, AP3 is the first node, and AP2 is the second node.

In an embodiment, the step S14 may be that the first node selects the second node to connect to the second node: the first node selects a second node for connection; the first node here is the first connection to the network. Therefore, the embodiment of the disclosure can enable the first node to find the appropriate second node for connection when the first node is accessed to the network for the first time.

In another embodiment, the step S14 may be that the first node selects the second node to connect, where: the first node selects a second node to carry out switching connection; here, the first node is switched from being connected to other nodes, which are nodes other than the second node in the network, to being connected to the second node. Therefore, the embodiment of the disclosure can enable the first node to be switched to a proper second node for connection communication again when the first node is connected to the third node; for example, the first node is already connected to the third node with poor communication quality, and a second node with good communication quality may be selected for connection.

Therefore, in the embodiment of the present disclosure, when the first node is accessed to the network for the first time, or the first node needs to determine the connection again, or the topology relationship in the network where the first node is located is changed, etc., the first node can be connected to the appropriate second node in time for communication, thereby improving the communication quality of the first node and ensuring efficient and stable connection of the network topology.

The preset rate condition here includes, but is not limited to, at least one of the following:

a condition that a second network egress rate is maximum;

a second network egress rate is greater than the predetermined port egress rate.

In some embodiments, the step S14 includes:

The first node has a second network egress rate when connected to a second node; if the number of the second node is one, the second network exit rate with the maximum second network exit rate is the second node; the first node may be connected to the second node. Or, if there are a plurality of second nodes, and the second network egress rate of the first node is multiple, the first node may select the second node corresponding to the maximum second network egress rate for connection.

In the disclosed embodiment, the network egress rate of the first node at each second node may be determined, and the second node corresponding to the maximum network egress rate is selected from the network egress rates for connection. Therefore, the first node can select the second node with the best communication quality as much as possible to be connected, so that the first node has the best communication quality as much as possible, and efficient and stable connection of the network topology is ensured.

Of course, in its embodiment, the step S13 may also include: selecting the second node corresponding to the second largest network exit rate from the at least one second node for connection; or, from at least one second node, selecting any second node corresponding to a second network exit rate greater than a predetermined network exit rate to connect. Thus, in the embodiment of the present disclosure, the first node may also select a suitable second node to connect, so that the first node has a better communication quality.

In some embodiments, the method further comprises:

selecting, from candidate nodes which emit the beacon signal, the candidate node corresponding to the first subnet identification which matches the second subnet identification of the first node as the second node

In one embodiment, the scanning for beacon signals comprises: the beacon signal of any one of the candidate nodes is scanned. An alternative node here is a node that sends out a beacon signal.

In one embodiment, the matching of the first networking identification and the second networking identification comprises: the first networking identification is the same as the second networking identification.

Illustratively, the second networking identifier of the first node is "01", and if the first networking identifier of the alternative node is also "01", it is determined that the alternative node is the second node. Here, if the first networking identifier of the candidate node indicates the candidate node, and the candidate node and the first node are the same network, determining that the candidate node is a second node to which the first node can be selected and connected; and if the first networking identification of the alternative node indicates that the alternative node is not the same network as the first node, determining that the alternative node is not the second node which can be selected by the first node for connection.

In the embodiment of the disclosure, a first networking identifier matched with a second networking identifier of a first node is selected from scanned beacon signals, and it is determined that a candidate node corresponding to the first networking identifier and the first node belong to the same network; it is determined that the second node is a second node from which the first node can select. Therefore, the method and the device can accurately determine which alternative nodes can be used for the first node to selectively connect, thereby accurately determining the second node, and enabling the first node to be connected to a proper network.

As shown in fig. 3, in some embodiments, the method comprises:

step S10: scanning for a beacon signal of the second node;

the step S11 includes:

step S111: determining the first network egress rate of the second node based on a network egress rate carried in the beacon signal.

In one embodiment, the beacon signal carries: network egress rate. For example, the first network egress rate of the second node is carried in a beacon signal sent by the second node.

In one embodiment, the step S11 includes: determining a network exit rate carried by a beacon signal of the second node as the first network exit rate of the second node. In another embodiment, the step S11 includes: and determining the network exit rate which is different from the network exit rate carried by the beacon signal of the second node by a preset value as the first network exit rate of the second node.

Therefore, in the embodiment of the present disclosure, the network exit speed of the second node can be accurately obtained based on the beacon signal of the second node; the first network egress rate of the second node may thus be determined based on the network egress rate carried in the beacon signal.

In some embodiments, the step S11 includes:

and the first node inquires an access interface of the second node, and acquires the network exit rate of the second node from the access interface of the second node as the first network exit rate.

For example, the beacon signal may be a beacon (beacon) frame. The beacon frame may be carried in an interface of the AP. As such, at least one predetermined field of the beacon frame herein may carry the network egress rate. In this way, the embodiment of the present disclosure may also be configured such that the first node searches the network egress rate from the access interface of the second node, so as to accurately obtain the first network egress rate of the second node.

In some embodiments, at least one of, but not limited to, the following may be carried in the beacon signal: network exit rate, inter-device rate, networking identification, access type identification and device attribute identification.

Here, the access type identifier of the node is used for indicating the access type of the node. For example, an access type identifier, indicating whether the first node or the second node is a node based on a wired access interface or a node based on a wireless access interface.

Illustratively, for example, if the access type identifier carried in the beacon signal scanned to the second node is a wired access identifier, the second node is accessed based on a wired access interface; for another example, if the access type identifier carried in the beacon signal of the scanned AP is a wireless access identifier, the second node is accessed based on a wireless access interface. The wired access identifier and the wireless access identifier can be any preset identifier; for example, the wired access identifier is "1" and the wireless access identifier is "0".

In another embodiment, the access type identifier includes: and (4) a wired access identifier. For example, if the beacon signal of the second node is scanned to carry the wired access identifier, the second node is accessed based on the wired access interface; for another example, if the beacon signal scanned to the second node does not carry the wired access identifier or does not carry any access type identifier, the second node is accessed based on the wireless access interface. Thus, in this embodiment, based on the protocol convention, if a wired access identifier, for example, "1", exists in the beacon signal of the second node, it is determined that the second node is accessed based on the wired access interface; and if the wired access identifier or any access type identifier does not exist in the beacon signal of the second node, determining that the second node is accessed based on the wireless access interface.

Here, the device attribute identifier of the node is used to indicate whether the node is a root node.

In one embodiment, the device attribute identification includes: and (4) identifying the network exit. For example, if the beacon signal of the second node is scanned to carry the network exit identifier, it is determined that the second node is the root node; for another example, if the beacon signal scanned to the second node does not carry the network exit identifier, it is determined that the second node is not the root node. The network exit identifier here may be any identifier that is predetermined; for example, it may be "1", "11", or "10", etc.

The device attribute identifier of the node may also be used to indicate whether the node is a root node, an intermediate node, or an end node. For example, if the device attribute identifier carried in the beacon signal of the second node is scanned as a network exit identifier, determining that the second node is a root node; if the device attribute identifier carried in the beacon signal of the second node is scanned to be the intermediate node exit identifier, determining that the second node is the intermediate node; and if the device attribute identifier carried in the beacon signal of the second node is scanned to be the end node identifier, determining that the second node is the end node.

Exemplarily, if a device attribute identifier carried in a beacon signal of a second node is "001", it is determined that the second node is a root node; if the equipment attribute identifier carried in the beacon signal of the second node is '002', determining that the second node is an intermediate node; and if the equipment attribute identifier carried in the beacon signal of the second node is '010', determining that the second node is the end node.

Here, the networking identifier of the node is used for indicating the network where the node is located. For example, if the network where the second node is located is network 1, the networking identifier of the second node may be "01"; for another example, if the network where the second node is located is network 2, the networking identifier of the second node may be "10".

In other embodiments, the access type identifier may also be other information, and only the requirement of the access type interface capable of indicating the AP is satisfied; the device attribute identifier may be other information, and only the information is required to indicate whether the AP is a root node; the networking identification can also be other information, and only the information is required to indicate the network where the AP is located; no limitation is made on what information is the access type identifier, the device attribute identifier, or the networking identifier.

In one embodiment, the access type identifier may be an optional field of a beacon signal. In one embodiment, the device attribute identification may be an optional field in the beacon signal. In one embodiment, the networking identification may be an optional field in the beacon signal.

Of course, in other examples, one or more fields of the beacon frame may also carry at least one of the following: the system comprises a wired access identifier, a wireless access identifier, a network exit identifier and a networking identifier. As such, in this embodiment of the present disclosure, the first node may also query the second node for an access type identifier, a device attribute identifier, and/or a networking identifier, etc.

As shown in fig. 4, in some embodiments, the method comprises:

step S10: scanning for a beacon signal of the second node;

the step S12 includes:

step S121: determining the inter-device rate of the second node based on an inter-device rate carried in the beacon signal;

alternatively, the first and second electrodes may be,

step S122: determining the inter-device rate of the second node based on a signal strength of the beacon signal. .

In one embodiment, the beacon signal carries an inter-device rate. For example, the beacon signal sent by the second node carries the inter-device rate from the second node to the first node.

In one embodiment, the inter-device rate may be obtained from protocol negotiation. For example, if the first node and the second node are connected by wire, the inter-device rate of the first node and the second node may be determined based on protocol negotiation between the first node and the second node. Here, the inter-device rate may also be stored in the second node.

In another embodiment, the inter-device rate may be determined based on the signal strength of the beacon signal. For example, if the first node and the second node are wirelessly connected, the rate of device reduction between the first node and the second node may be determined based on the signal strength between the first node and the second node.

Here, the inter-device rate is positively correlated with the signal strength of the beacon signal. For example, a signal strength between the first node and the second node is greater than a first signal strength, and an inter-device rate between the first node and the second node is greater than a first rate; a signal strength between the first node and the second node is less than a second signal strength, and an inter-device rate between the first node and the second node is less than a second rate; the first signal strength is greater than the second signal strength, and the first rate is greater than the second rate.

In an embodiment of the present disclosure, a first node receives a beacon signal of a second node; if the beacon signal of the second node carries the inter-device rate, the first node may accurately acquire the inter-device rate between the first node and the second node based on the inter-device rate in the beacon signal of the second node.

Or the first node receives a beacon signal of the second node, and accurately determines the inter-device rate between the first node and the node based on the signal strength of the beacon signal of the second node.

In some embodiments, the beacon signal carries: an access type identifier;

the step S122 includes:

In an embodiment, the working protocol and the number of the wireless spatial streams of the second node may be carried in a beacon signal sent by the second node, and the working protocol and the number of the wireless spatial streams of the second node may also be stored in at least one node of the Mesh network after negotiation through a communication protocol.

In one embodiment, the working protocol of the second node may be, but is not limited to, a 2G, 3G, 4G, or 5G, etc. specified related communication protocol. Different working protocols have different corresponding coding efficiency; and the coding efficiency of data affects the data transmission between nodes. It should be noted that, if the release time of the node working protocol is closer to the current time, the rate between the nodes and the devices of the nodes is relatively higher; if the release time of the node working protocol is farther from the current time, the rate between the nodes and the equipment of the nodes is relatively smaller. For example, the inter-device rate corresponding to the case where the protocol of the first node and the second node are operated in the 5G related communication protocol is greater than the inter-device rate corresponding to the case where the protocol of the first node and the second node are operated in the 4G related communication protocol.

Here, the wireless spatial stream refers to: when a radio transmits multiple signals at the same time, each signal is a spatial stream. As described above, the number of wireless spatial streams may be the number of signals transmitted at the same time.

In an embodiment, the number of wireless spatial streams between a first node and a second node is positively correlated with the inter-device rate of the first node and the second node. For example, if the number of wireless spatial streams between a first node and a second node is 2, then the inter-device rate between the first node and the second node is twice that of the number of wireless spatial streams 1.

In another embodiment, the step S132 includes: determining the inter-device rate from the first node to the second node based on at least one of a strength of the beacon signal, an operating protocol of the second node, and a number of wireless spatial streams.

In the embodiment of the present disclosure, the first node may accurately determine the inter-device rate from the first node to the second node based on the strength of the scanned beacon signal, the working protocol of the second node, and/or the number of wireless spatial streams, so that the inter-device rate between the first node and the second node may be accurately obtained in multiple ways.

As shown in fig. 5, in some embodiments, the beacon signal carries: an access type identifier;

the step S13 includes:

step S131: if the access type identifier is a wireless access identifier, determining a second network exit rate when the first node is connected with the second node based on the first network exit rate, the inter-device rate and a loss factor; wherein the impairment factor is indicative of a degree of impairment of the first network egress rate and/or the inter-device rate;

or;

step S132: and if the access type identifier is a wired access identifier, determining the second network exit rate when the first node is connected with the second node based on the smaller value of the first network exit rate and the inter-device rate.

In one embodiment, the size of the impairment factor is inversely related to the degree of impairment of the network transmission rate.

In one embodiment, the impairment factor may be determined based on the ambient environment of the network.

For example, if the first node determines that other nodes in the network send data, it is determined that the depreciation factor is relatively small; and if the first node determines that no other node in the network sends data, determining that the impairment factor is relatively large. In this example, if there are other nodes in the network that occupy the channel and need to send data, the first node needs to monitor when sending data, and sends data after determining that the channel is idle; in this way, the data sent by the first node is lost in time, which results in a relatively large degree of impairment of the network transmission rate, i.e., a relatively small impairment factor.

For another example, if it is determined that a specific object exists between the first node and the second node, it is determined that the breakage factor is relatively small; if no specific object exists between the first node and the second node, the breakage factor is determined to be relatively large. A particular object herein includes, but is not limited to, a person. In this example, if a first node sends data to a second node, and there is a person between the first node and the second node, the signal strength of the data sent by the first node is weak, and the data is interfered by the person; resulting in a relatively large impairment of the network transmission rate, i.e. a relatively small impairment factor.

In another embodiment, the impairment factor may be preset. For example, a break factor of 0.7, 0.6, or 0.8, etc. may be set.

In one embodiment, the step S131 includes:

determining a first ratio based on the first value and the second value;

For example, if the second network egress rate of the first node connected to the second node is V1, the first network egress rate of the second node is V2, the inter-device rate between the first node and the second node is V3, and the breakage factor is Q, then the rate is equal to or higher than the first network egress rate

In an embodiment, if the access type identifier is a wired access identifier, the determined second network egress rate when the first node is connected to the second node may be a smaller value of the first network egress rate of the second node and the inter-device rate.

In another embodiment, if the access type identifier is a wired access identifier, the determined second network egress rate when the first node is connected to the second node may be a rate that is different from the smaller of the first network egress rate of the second node and the inter-device rate by a predetermined value.

In this embodiment of the present disclosure, if the second node is a wireless access node, the first network egress rate when the first node is connected to the second node may be determined more accurately according to the first network egress rate of the second node, the inter-device rate, and the impairment factor. In particular, in the embodiment of the present disclosure, the loss condition of the network transmission rate (that is, the rate between the first node and the second node and the network egress rate from the second node to the root node) when data is transmitted between the nodes is also considered, and the estimation may be performed according to the actual condition, so as to further improve the accuracy of the determined second network egress rate at which the first node is connected to the second node.

Or, if the second node is a node of wired access, it may determine a relatively accurate second network port exit rate at which the first node is connected to the second node according to a smaller value of the first network exit rate of the second node and the inter-device rate from the first node to the second node. It can be understood that, if the second node is a wired access node, the wired access node does not need to monitor the transmission of the data packet like a wireless access interface-based access node, so that the rate of the wired access node data is less damaged during transmission; in this way, a second network egress rate for the first node when connected to the second node may be determined based on the first network egress rate for the first node being connected to the second node being the lesser of the network egress rate of the second node and the inter-device rate of the first node to the second node.

In one embodiment, a beacon signal of the second node is scanned, wherein the beacon signal carries a device attribute identifier;

the step S12 includes:

For example, if the device attribute identifier carried in the beacon signal of the second node indicates that the second node is the root node and the second node is a node to which the wireless access interface is accessed, the second network egress rate when the first node is connected to the second node is determined based on the inter-device rate from the first node to the second node.

Thus, in the embodiment of the present disclosure, if the second node is a root node, the second network egress rate when the first node connects to the second node may be determined directly from the inter-device rate from the first node to the second node. For example, the second portal egress rate when the first node connects to the second node is determined to be the inter-device rate between the first node and the second node, or the second portal egress rate when the first node connects to the second node is determined to be: a rate different by a predetermined value from an inter-device rate between the first node and the second node. In this way, obtaining the second network egress rate when the first node connects to the second node can be simplified.

In some embodiments, the method comprises:

if the device attribute identifier indicates that the second node is the root node, determining the second network exit rate when the first node is connected with the second node based on the inter-device rate;

The first network egress rate of the parent node here means: network transmission rate between parent node and root node.

The second network egress rate of the intermediate node here means: network transmission rate between the intermediate node and the root node; the second network egress rate of the end node here means: network transmission rate between the end node and the root node.

Thus, in the embodiment of the present disclosure, the nodes of the Mesh network may acquire the second network exit rate from the node to the root node from the root node to the intermediate node to the end node. Thus, on the one hand, a second node (whether it is a root node, an intermediate node, or an end node) is enabled to connect to a suitable upstream node for communication; on the other hand, the updating of the topological relation of each node in the whole Mesh network is realized, so that each node finds a proper uplink node for connection. Therefore, the communication quality of the whole Mesh network can be improved.

As shown in fig. 6, in some embodiments, the step S14 includes:

step S141: and if the network connection condition of the first node meets a preset switching condition, selecting the second node with the second network exit rate meeting a preset rate condition from at least one second node to connect.

In the disclosed embodiment, the first node is connected with other nodes in the network; for example, the first node is connected to the third node, but the signal strength of the communication between the first node and the third node is relatively weak, for example, less than a predetermined strength threshold; the first node may select the second node whose second network egress rate satisfies the preset rate condition for connection.

Or, if the network egress rate of the first node connected to the current node (e.g., the third node) is smaller than the egress rate of the first node connected to the second node, that is, the second node corresponding to the maximum value of the at least one second network egress rate of the first node is not the currently connected node; if the first node is connected to the second node, the second network exit rate is greater than or equal to the preset rate of the first node connected to the current node; the first node may also select the second node whose second network egress rate satisfies the preset rate condition for connection.

Therefore, in the embodiment of the present disclosure, communication can be performed on nodes to which the first node is already connected, but the communication quality is not good, so that the first node can be switched to be connected to a second node with good communication quality, and further, the communication quality of the first node is improved, and efficient and stable connection of a network topology is ensured.

In addition, in the embodiment of the present disclosure, instead of switching to the second node to connect when the first node determines that the network egress rate is relatively large or the network egress rate is the maximum value when the first node determines that the first node is connected to the second node, the second node is switched to connect when the signal strength of communication between the first node and the currently connected node is required to be smaller than the predetermined strength threshold. Therefore, the situation that the connection is frequently switched to different nodes for connection can be reduced; therefore, the connection of the first node is more stable, and the stable connection of the whole network where the first node is located is improved.
