Referring to fig. 1, fig. 1 is a schematic flow chart of a method for establishing a network connection according to a first embodiment of the present application. An execution subject of the method for establishing a network connection in this embodiment is a core device (CAP) in a Mesh ad hoc network. The method for establishing network connection as shown in fig. 1 may include:
s101: and determining the networking equipment which detects the networking request of the equipment to be networked as candidate equipment.
Mesh ad hoc networks are a new type of wireless network that is completely different from traditional wireless networks. The method is a technology for dynamically establishing new links to connect with other nodes, has the advantages of convenient configuration and intelligent networking, and can greatly reduce the cost and complexity of network deployment. The Mesh ad hoc network product is used as a new product form and replaces the model of an Access control Point router (AP) + an auxiliary equipment expander (RE) under a large-area Wi-Fi coverage scene.
In order to facilitate pairing and network access between Mesh devices, a WiFi Protected Setup (WPS) mode is generally used for authentication and access of the devices. In the process of establishing the network connection, the WPS keys of the device to be accessed to the network and the wireless routing device can be pressed respectively to establish the connection quickly, and the connection can also be established by the two parts through clicking the keys on the virtual page. In the WPS of the push button system, the validity period of one push button is 2mins, and therefore, the interval between two push buttons needs to be within 2 mins. And due to the limitation of the distance of wireless transmission, the spatial distance between two devices performing the WPS cannot be very long, so that the success of wireless transmission can be ensured.
In a scene of actually using a network, the positions of core devices in Mesh ad hoc networks in most scenes are fixed at a certain position. For example, for a residence, the core devices in most residential Mesh ad hoc networks are at one end of the room. In order to extend the coverage of the network, the extender RE1 is typically accessed at the edge of the coverage of the core device, and if the subscriber is large and flat, then the extender RE2 may be accessed at the edge of the extension range of the extender RE1 to increase the coverage, and the extender RE2 can only receive the signal of the extender RE 1. However, such coverage is still limited and increases the cost of the device. In this embodiment, a method for establishing a network connection is provided to solve the above problem. When the device to be networked initiates a WPS session, the device detects a network access request, and the device may select one authentication node device from the candidate devices to establish a network connection with the device to be networked.
Specifically, when the device to be networked initiates the WPS session, the device to be networked initiates a network access request. The device to be networked is an active party in the formal pairing process, so the device to be networked needs to actively discover the networked device first, and then the device to be networked sends a network access request. When networking equipment in a current network connected with the core equipment receives a network access request of equipment to be accessed, the networking equipment feeds the network access request back to the core equipment, namely to a decision center (CAP equipment or AC equipment).
The core device determines the networked device which detects the network access request of the device to be accessed as a candidate device. The core device selects one device from the candidate devices as an authoritative authentication node capable of issuing the certificate to provide network access for the device to be networked.
The embodiment also supports that multiple devices to be networked initiate a WPS session at the same time, and multiple devices to be networked initiate a network access request for joining the current network at the same time. That is to say, in this embodiment, the number of the devices to be networked is one or more.
When multiple sessions are supported, a plurality of devices to be networked initiate networking requests at the same time, the plurality of devices to be networked may be allocated to interact with different networking devices, and according to a manufacturing automation standard Protocol (MAP), the core device may determine that a plurality of networking devices exist at the same time, and overlap occurs, so that WPS is not performed. To solve this problem, the following solutions are proposed in the present embodiment:
1. a core device, namely a decision center (CAP device or AC device), uniformly configures a unique identifier (UUID) of a networked device, so that The networked devices are considered as The same node by a device to be networked;
2. modifying the maintenance mode of the equipment to be networked on the scanning list, not pairing with the networked equipment only with the Beacon frame, and only regarding the items updated according to the unicast Probe Resp frame as legal networked equipment;
3. and adding the MAC address list of the corresponding equipment to be networked in the Vendor-defined information element Vendor IE of the Beacon/Probe Resp of the networked equipment, and stating that the WPS is open to the equipment to be networked, thereby ensuring that the equipment to be networked can correctly distinguish which networked equipment is specific to the equipment.
When a new device to be networked triggers WPS, there may be multiple devices already networked in the Mesh network that may all discover the new device to be networked, and due to complexity of topology, such as chaining, discovery message transfer delay, etc., the device already networked that is discovered first may not necessarily be the best access device, i.e., the best access device. Therefore, when the core device receives a WPS access request from a device to be networked sent by a certain networked device for the first time, a delay selection timer is started to check whether other networked devices discover the device to be networked, a plurality of networked devices capable of discovering the device to be networked are obtained, and the best authentication node is selected from the plurality of networked devices, so that the networked device with better signal can be selected as the access device of the device to be networked. Therefore, when determining as a candidate device, S101 may include S1011 to S1012, as shown in fig. 2, S1011 to S1012 specifically are as follows:
s1011: and when receiving the network access request sent by the equipment to be networked or receiving the network access request forwarded by the networking equipment, executing timing operation with preset time length.
And when the core equipment receives a network access request sent by the equipment to be networked or receives a network access request forwarded by the networking equipment, starting a delay selection timer and executing timing operation with preset time length. And detecting whether other networking equipment which detects the networking request of the equipment to be networked still exists or not within a preset time length.
S1012: and after the timing operation is finished, determining the networking equipment which detects the network access request of the equipment to be accessed as candidate equipment.
After the timing operation is finished, all the networked devices which detect the network access request of the device to be accessed are determined as candidate devices, so that the quality of the candidate devices can be improved, and the optimal authentication node can be selected more easily to serve as the access device of the device to be accessed.
S102: and acquiring link information of each candidate device, and determining authentication node equipment from the candidate devices according to the link information and a preset selection strategy.
The equipment acquires link information of each candidate equipment, and determines authentication node equipment from the candidate equipment according to the link information and a preset selection strategy. The link information refers to link connection information between the candidate device and the device to be networked. The link information is used as a reference factor for selecting an authentication node device.
The core device stores a preset selection policy in advance, and the preset selection policy is used for determining the authentication node device from the candidate devices. The preset selection policy may be set according to actual conditions and considerations for selecting authentication node devices.
In a specific embodiment, when the authentication node device is selected, the pairing speed is mainly considered, and since the wired pairing speed is much higher than the wireless pairing speed, S102 may determine the authentication node device in the manners of S1021 to S1022, and select a networked device with a faster pairing speed as the authentication node device, as shown in fig. 3, S1021 to S1022 are specifically as follows:
s1021: and obtaining the link type between each candidate device and the device to be networked.
And obtaining the link type between each candidate device and the device to be networked. The link types include wired connections and wireless connections. When connected by wire, a link refers to a physical line, such as a cable or fiber, between two nodes. In the case of wireless connection, a link refers to a path space for electromagnetic waves propagating between a base station and a terminal.
S1022: and determining the candidate equipment with the link type being wired connection as the authentication node equipment.
Since the wired pairing speed is much higher than the wireless pairing speed, when there is both a wired connection and a wireless connection, a candidate device that preferentially selects a link type as a wired connection is determined as an authentication node device.
Further, if the device to be networked has a wired connection with multiple candidate devices at the same time, S1022 may include S10221 to S10222, as shown in fig. 4, S10221 to S10222 are specifically as follows:
s10221: and determining the candidate device with the link type being the wired connection as the alternative device.
The core device obtains that a plurality of candidate devices are in wired connection with the device to be networked at the same time, and determines the candidate device with the link type in wired connection as the candidate device.
S10222: and determining the alternative equipment which detects the network access request firstly as the authentication node equipment.
The core device may be configured to select the candidate device that receives the network access request earliest as the authentication node device, that is, the core device obtains the time when each candidate device detects the network access request, and determines the candidate device that detects the network access request earliest as the authentication node device.
Further, in selecting the authentication node device, in addition to the pairing speed, the signal quality may be considered. After S1021, S1023 to S1024 may be further included, and as shown in fig. 5, S1023 to S1024 are specifically as follows:
s1023: if all the link types are in wireless connection, acquiring a received signal strength indication detected by each candidate device; the received signal strength indication is a signal strength indication between the candidate device and the device to be networked.
In this embodiment, if it is detected that all the current candidate devices and the device to be networked are in wireless connection, that is, the link types acquired by the device are all in wireless connection. At this time, the factor of the signal quality is prioritized when determining the authentication node device. The core device obtains the received signal strength indication detected by each candidate device, wherein the received signal strength indication is the signal strength indication between the candidate device and the device to be networked, that is, the quality of each wireless link is obtained.
S1024: and determining the candidate device with the highest received signal strength indication or the received signal strength indication higher than a preset threshold value as the authentication node device.
The core device preferentially determines the candidate device with the highest received signal strength indication as the authentication node device, namely selects the candidate device with the highest link quality to determine as the authentication node device; or a preset threshold value is preset in the core device, and the candidate device with the received signal strength indication higher than the preset threshold value is determined as the authentication node device.
S103: generating a connection message and sending the connection message to the authentication node equipment; the connection message is used for triggering the authentication node equipment to respond to the network access request and establishing network connection with the equipment to be accessed.
The core equipment generates a connection message and sends the connection message to the authentication node equipment, and the connection message is used for triggering the authentication node equipment to respond to the network access request and establish network connection with the equipment to be accessed. After the core device selects the authentication node device, the authentication node device and the device to be accessed to the network are appointed to complete the WPS session, the device to be accessed to the network is determined to be capable of establishing network connection with the authentication node device, the device to be accessed to the network can enter a pairing mode, a wireless network name and a password sent by the authentication node device are received, and network connection is established with the authentication node device based on the received wireless network name and the password.
In the embodiment of the application, the networking equipment which detects the network access request of the equipment to be accessed is determined as candidate equipment; acquiring link information of each candidate device, and determining authentication node devices from the candidate devices according to the link information and a preset selection strategy; generating a connection message and sending the connection message to authentication node equipment; the connection message is used for triggering the authentication node equipment to respond to the network access request and establish network connection with the equipment to be accessed. In the scheme, the Mesh network is regarded as a whole, and all the networked devices can be used as authentication node devices to access the devices to be accessed to the network, so that the Mesh network is not limited to pairing the core devices and the devices to be accessed to the network. Therefore, the coverage range of one device of the core device is not limited, and the networked device at any position can be accessed to the device to be networked, thereby greatly expanding the coverage range of the Mesh network. And the coverage range of the Mesh network can be expanded without arranging an expander, so that the equipment cost is reduced.
