Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, in a networking scheme of an internet of things device with default Android and Linux systems, if a plurality of wireless networks with the same network name and different passwords exist currently, the internet of things device in a wireless roaming state selects to initiate a connection request to a wireless network with the best signal currently, and does not initiate a connection request to a wireless network with poor signal. This results in that if the signal of the wireless network to which the user specifies to connect is poor, the wireless network will always be in a connection failure state, thereby seriously affecting the user experience.
Therefore, the internet of things equipment distribution network scheme is correspondingly provided, the situation that the internet of things equipment in a wireless roaming state only initiates a connection request to the wireless network with the best current signal can be avoided, and the internet of things equipment can be favorably connected with the wireless network appointed by a user smoothly.
Referring to fig. 1, an embodiment of the application discloses a network distribution method for internet of things equipment, which is applied to the internet of things equipment and includes:
step S11: first network information specified by a user terminal is acquired.
In this embodiment, the first network information is network information specified by the user terminal. In one embodiment, the first network information may be determined at the user terminal by manual configuration. Specifically, the user terminal obtains configuration parameters input by a user through a preset interface, and then determines the first network information according to the configuration parameters. In another specific embodiment, after the user terminal establishes a connection with any wireless network, the user terminal records corresponding network information and terminal location information into a preset historical successful connection network list. When the first network information needs to be determined, the user terminal searches out the network information corresponding to the current position information of the user terminal from the historical successful connection network list by using the current position information of the user terminal as the first network information.
In this embodiment, the first network information may specifically include, but is not limited to, the following network parameters: network name, network password, BSSID (i.e., MAC address), and network encryption type. In addition, the first network information in this embodiment may specifically include network information of one or more wireless networks.
It is understood that, in the present embodiment, the terminal type of the user terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, and the like.
In a specific embodiment, the obtaining the first network information specified by the user terminal may include: first network information designated and transmitted by a user terminal in real time is acquired. That is, in this embodiment, the first network information acquired by the internet of things device may specifically be network information specified in real time on the user terminal.
In another specific embodiment, the obtaining of the first network information specified by the user terminal may include: and acquiring first network information which is pre-stored locally and is specified by the user terminal in the past. That is, in this embodiment, the first network information acquired by the internet of things device may specifically be the first network information that has been specified by the user terminal historically.
In a third specific embodiment, the acquiring the first network information specified by the user terminal may include: the method comprises the steps of obtaining first network information which is specified and sent by a user terminal in real time and obtaining first network information which is pre-stored locally and specified by the user terminal in the past. That is, in this embodiment, the first network information acquired by the internet of things device includes both the first network information specified by the current user terminal in real time and the first network information that has been specified by the user terminal historically.
Step S12: and starting a network scanning function to acquire second network information.
It can be understood that after the internet of things device starts the network scanning function, all wireless networks in the current environment of the internet of things device may be scanned to obtain network information of all wireless networks, so as to obtain the second network information. In addition, the second network information specifically includes, but is not limited to, the following network parameters: network name, MAC address, etc. In the practical application process, a plurality of wireless networks with the same network name often appear in the surrounding environment, which directly causes that a plurality of wireless networks with the same network name exist in all the wireless networks scanned by the internet of things equipment after the network scanning function is started. It is understood that the MAC addresses of the wireless networks with the same name are different. In addition, it should be noted that, among the plurality of wireless networks with the same network name, some wireless networks have network names set by the network owner without intention, and are not set intentionally by a person, and some wireless networks may be set intentionally by a hacker, and these networks have very strong signal strength and have the same network name as other surrounding normal networks under the intentional setting of the hacker. In this case, if the existing distribution network scheme is adopted, the internet of things device always sends a connection request to the wireless networks built by hackers, so that the wireless network specified by the user cannot be connected. The problem can be effectively solved by the distribution network scheme provided in the embodiment.
Step S13: and screening out the network information which is consistent with the first network information from the second network information to obtain a corresponding network set.
In this embodiment, the internet of things device may specifically screen out, from the second network information, all network information that matches the first network information on any network parameter or any several network parameters, so as to obtain the network set.
Step S14: and screening out one network with the best signal quality from all the networks in the effective state in the network set as a target network, and initiating a connection request aiming at the target network.
In this embodiment, after the network set is obtained in step S13, one wireless network with the best signal quality is selected from all valid networks in the network set that have not been marked as invalid states as a current target network, and then a connection request is initiated for the currently selected target network. It should be noted that if the currently screened target network is consistent with the network in the first network information, the connection may be successfully established, and conversely, if the currently screened target network is not consistent with the network in the first network information, the connection may be failed. In addition, it can be understood that, the connection request initiated by the internet of things device for the target network may include the following parameters: network name, network password, network encryption type, and may additionally include MAC address, etc.
In this embodiment, in order to enable the user to more vividly and intuitively see the difference between the signal qualities of the wireless networks in the current network set, different scores may be performed on all the effective networks in the network set according to the difference between the signal strengths, where the larger the signal strength of the wireless network is, the higher the obtained score is, and then, one effective network with the highest current score is directly determined as the target network.
Step S15: and if the connection fails, marking the state of the target network as an invalid state, and executing the step of starting the network scanning function again until a preset distribution network flow end condition is met.
That is, if the connection initiated for the target network in step S14 fails, the state of the target network is marked as an invalid state, and step S12 is re-entered until the preset distribution network flow end condition is met. In this embodiment, the distribution network flow ending condition may specifically be that when the internet of things device successfully connects to the wireless network, or that there is no valid network in the network set obtained in step S13. In addition, in this embodiment, when the internet of things device is successfully connected to the network or the connection fails, corresponding prompt information may be generated, and the prompt information may be sent to the user terminal to prompt the user of the corresponding distribution network result.
Further, if the internet of things device cannot scan any wireless network after starting the network scanning function, that is, obtains a blank second network information, the internet of things device background may add the network information of a pre-default wireless network to the blank second network information, so as to reduce the probability that the internet of things device cannot be connected to the network. The network information of the pre-default wireless network may specifically include a network name, a network encryption type, a network password, and the like, but does not include a MAC address.
Therefore, in the embodiment of the application, after connection initiated by any network fails, the state of the network is set to be in an invalid state, then a new round of network scanning is performed to obtain a new network set, and when a target network is selected from the network set, specifically, one network with the best signal quality is selected from all networks in the valid state of the network set as the target network, so that the situation that the previous network which cannot be connected is selected again as the target network can be avoided, that is, the situation that the internet of things equipment only initiates a connection request to the current wireless network with the best signal can be avoided, and the smooth connection of the internet of things equipment to the wireless network which is specified to be connected by a user is facilitated.
Referring to fig. 2, an embodiment of the application discloses a network distribution method for internet of things equipment, which is applied to the internet of things equipment and includes:
step S21: first network information including a network name and a network password specified by a user terminal is acquired.
Step S22: and starting a network scanning function to acquire second network information.
Step S23: and screening out the network information which is consistent with the network name in the first network information from the second network information to obtain a corresponding network set.
Step S24: and screening out one network with the best signal quality from all the networks in the effective state in the network set as a target network, and initiating a connection request aiming at the target network.
Step S25: and if the connection fails, marking the state of the target network as an invalid state, and executing the step of starting the network scanning function again until a preset distribution network flow end condition is met.
That is, in this embodiment, the first network information specified by the ue includes the following two network parameters: a network name and a network password. After the internet of things equipment starts a network scanning function to obtain second network information, the first network information and the second network information are compared to collect network information in the second network information, wherein the network information conforms to the network name in the first network information, and a corresponding network set is obtained. Since there may be some wireless networks in the network set that have been marked as invalid before, in the embodiment, when screening the current target network, specifically, one network with the best signal quality is screened from all the networks in the valid state in the current network set as the target network, and then a connection request is initiated for the target network. If the current target network does not belong to the network in the first network information, the connection fails, and then the step S22 is re-entered, and if the current target network belongs to the network in the first network information, the connection is successful, so that the internet of things device can connect to the network specified by the user terminal while implementing wireless roaming.
Referring to fig. 3, an embodiment of the application discloses a network distribution method for internet of things equipment, which is applied to the internet of things equipment and includes:

Step S32: and starting a network scanning function to acquire second network information.
Step S33: and screening out the network information which is consistent with all the MAC addresses in the first network information from the second network information to obtain a corresponding network set.
Step S34: and screening out one network with the best signal quality from all the networks in the effective state in the network set as a target network, and initiating a connection request aiming at the target network.
Step S35: and if the connection fails, marking the state of the target network as an invalid state, and executing the step of starting the network scanning function again until a preset distribution network flow end condition is met.
That is, in this embodiment, the first network information specified by the ue includes the following three network parameters: network name, network password, and MAC address. After the internet of things equipment starts a network scanning function to obtain second network information, the first network information and the second network information are compared to collect network information in the second network information, wherein the network information conforms to the MAC address in the first network information, and a corresponding network set is obtained. Because the MCA address and the wireless network can only be in one-to-one correspondence, and the network name and the wireless network can be in one-to-many correspondence, the network set obtained based on the MAC address has fewer redundant networks than the network set obtained based on the network name, so that the connection request initiating amount of each round of distribution network process is greatly reduced, and the speed of connecting the Internet of things equipment to the user-specified network is greatly improved. In addition, since there may be some wireless networks marked as invalid states before in the network set of the present embodiment, when screening the current target network, specifically, when screening all the networks in valid states in the current network set, the present embodiment screens out one network with the best signal quality as the target network, and then initiates a connection request for the target network. If the current target network does not belong to the network in the first network information, the connection fails, and then the step S32 is re-entered, and if the current target network belongs to the network in the first network information, the connection is successful, so that the internet of things device can connect to the network specified by the user terminal while implementing wireless roaming.
Referring to fig. 4, an embodiment of the application discloses a network distribution method for internet of things equipment, which is applied to the internet of things equipment and includes:
step S41: first network information specified by a user terminal is acquired.

Step S44: and eliminating the networks marked as invalid states in the distribution network process of the current round from the network set to obtain the current valid network.
That is, in this embodiment, after the corresponding network set is obtained in step S43, the network that has been marked as the invalid state in the distribution process of the current round is removed from the network set, and if such processing is not performed, the internet of things device continues to initiate a connection request again for the wireless network that has been marked as the invalid state in the distribution process of the current round, so that the internet of things device is always connected to the network that is not specified by the user.
Step S45: and screening out one network with the best signal quality from the current effective networks as a target network, and initiating a connection request aiming at the target network.
Step S46: and if the connection fails, marking the state of the target network as an invalid state, and executing the step of starting the network scanning function again until a preset distribution network flow end condition is met.
Referring to fig. 5, an embodiment of the application discloses a network distribution method for internet of things equipment, which is applied to the internet of things equipment. In this embodiment, after the process of each distribution network is finished, the network marked as the invalid state may be recorded in a first historical invalid network list preset locally. Correspondingly, the method comprises the following steps:
step S51: first network information specified by a user terminal is acquired.
Step S52: and starting a network scanning function to acquire second network information.
Step S53: and screening out the network information which is consistent with the first network information from the second network information to obtain a corresponding network set.
Step S54: and removing the networks marked as invalid states in the distribution network process of the current round and the networks in the first historical invalid network list from the network set to obtain the current valid network.
That is, compared to the previous embodiment, in this embodiment, in addition to removing the networks that have been marked as invalid in the distribution network process of the current round from the network set, the network in the first historical invalid network list that is preset locally is also removed. The first historical invalid network list records the networks marked as invalid states in the process of each distribution network in the past. Through the processing, the invalid network in the network set can be determined at a higher speed, and the distribution speed of the whole distribution network process is greatly improved.
