Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
With the development of the multi-band wireless network technology, more and more routers and terminal devices can support multiple bands, so that the internet of things device can use different frequency bands to connect networks when performing wireless network connection. However, in the prior art, the multiband switching method applicable to the wireless network of the internet of things device is only applicable to the case of the same SSID. For a multi-band wireless network, when SSIDs are different, switching of the wireless network can only be performed in a manual network re-distribution mode, seamless switching of the wireless network cannot be achieved, and user experience is poor.
In order to solve the problems in the prior art, the application provides a multi-band switching method of a wireless network, which includes the steps of obtaining a current MAC address of a currently connected wireless network, scanning MAC addresses and RSSIs of a plurality of wireless networks in other frequency bands, and selecting a matched wireless network from the plurality of wireless networks for connection according to the current MAC address of the currently connected wireless network and the MAC addresses and the RSSIs of the plurality of wireless networks in the other frequency bands. Therefore, under the condition that SSIDs of all frequency bands of the multi-band wireless network are different, automatic switching of the wireless network can be realized.
In order to better understand the above technical solutions, a multiband handover method, an apparatus, an internet of things device, and a computer-readable storage medium of a wireless network according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a multiband handover method of a wireless network according to an embodiment of the present disclosure.
The embodiment of the present application is exemplified by the multiband switching method of the wireless network being configured in a multiband switching apparatus of the wireless network, and the multiband switching apparatus of the wireless network can be applied to any terminal device, so that the terminal device can execute the multiband switching method of the wireless network.
The terminal device may be a Personal Computer (PC), a cloud device, a mobile device, and the like, and the mobile device may be a hardware device having various operating systems, touch screens, and/or display screens, such as a mobile phone, a tablet Computer, a Personal digital assistant, a wearable device, and an in-vehicle device, and is not limited herein.
As shown in fig. 1, the multiband handover method of the wireless network includes the following steps:
step 101, a current Media Access Control (MAC) address of a current connected wireless network is obtained.
Among them, a Media Access Control (MAC) address, also called a physical address or a hardware address, is used to define a location of a network device. The MAC address is represented by hexadecimal numbers, has six bytes (48 bits), is set when the network card leaves a factory, and is fixed. It can be understood that the MAC address is globally unique as the identification number on our identification card.
In the embodiment of the application, the current MAC address of the wireless network connected with the current Internet of things equipment can be acquired in the configuration of the Internet of things equipment through the wireless network communication module of the Internet of things equipment.
As another possible implementation manner, the current MAC address of the wireless network to which the internet of things device is currently connected may also be acquired in a router connected to the internet of things device.
As another possible implementation manner, the current MAC address of the internet of things device currently connected to the wireless network may also be obtained in an application program on the terminal device for performing network distribution on the internet of things device.
Step 102, scanning MAC addresses and Received Signal Strength Indicator (RSSI) of a plurality of wireless networks in other frequency bands.
Among them, the Received Signal Strength (RSSI) is a positioning technique that measures the distance between a Signal point and a receiving point according to the Strength of the Received Signal and then performs positioning calculation according to the corresponding data, the RSSI attenuates with the increase of the distance between the wireless network and a router, and is generally a negative value, and the closer the value is to zero, the higher the Signal Strength is.
It should be explained that the frequency band refers to the frequency range of electromagnetic waves, and has a low frequency, a medium frequency and a high frequency. In a wireless network, there are 2G, 3G, 4G and 5G operating bands, for example, the operating bands of 5G are: 3300MHz-3600MHz frequency band and 4800MHz-5000MHz frequency band. The multi-frequency wireless network refers to a wireless network that supports multiple wireless signals in different frequency bands, for example, a dual-frequency wireless network can support wireless signals in two different frequency bands, and the two network segments are 2.4G and 5G, respectively.
In the embodiment of the application, the wireless network communication module of the internet of things device can scan the wireless networks in other frequency bands to obtain basic information of the wireless networks in other frequency bands, including whether the scanned state of the wireless network is available, SSID information, the used transmitting frequency band, whether the wireless network encrypts transmission, RSSI signal strength, basic transmission speed mode of a target wireless network, MAC addresses of wireless routers or wireless networks, wireless network composition mode (point-to-point or point-to-multipoint), connection time and other basic information.
As a possible implementation manner, the router synchronizes the wireless network connection by sending Beacon broadcasts, Beacon broadcasts a data packet to the surroundings at regular intervals, and the Beacon receives the data packet broadcasted by Beacon at intervals when performing a scanning action as an independent internet of things device. The packet content may contain up to 31 bytes of content. Meanwhile, when the internet of things equipment receives the broadcast packet, the MAC address (each Beacon has a unique MAC address) of which router the broadcast packet comes from and the current RSSI of receiving and sending are indicated.
And 103, selecting a matched wireless network from the plurality of wireless networks for connection according to the current MAC address of the currently connected wireless network, and the MAC addresses and the RSSIs of the plurality of wireless networks in other frequency bands.
In the embodiment of the application, the current MAC address of the currently connected wireless network is matched with the MAC addresses of a plurality of wireless networks of other frequency bands, the first ten bits of the MAC addresses are the same, namely MAC address matching is conducted, and then N wireless networks with matched MAC addresses are selected from the plurality of wireless networks to serve as alternative wireless networks, wherein N is a positive integer.
Further, firstly, the RSSI of the N alternative wireless networks is obtained, the multiple alternative wireless networks are screened according to the RSSI of the N alternative wireless networks, and the matched wireless networks are selected from the N alternative wireless networks for connection.
In the embodiment of the application, the frequency band of the currently connected wireless network can be compared with the frequency bands of the alternative wireless networks, and if the frequency band of the currently connected wireless network is greater than the frequency bands of the alternative wireless networks, the multi-frequency band switching of the wireless network is switched from high frequency to low frequency; if the frequency band of the current connected wireless network is smaller than the frequency bands of the plurality of alternative wireless networks, the multi-band switching of the wireless network is switched from low frequency to high frequency.
As a possible scenario, when the wireless network is switched from a low frequency to a high frequency, the RSSI of the N candidate networks is compared with a preset RSSI threshold, and a candidate network with the RSSI larger than a first preset threshold of the wireless network is selected from the N candidate networks for connection.
As another possible scenario, when the wireless network is switched from a high frequency to a low frequency, the RSSI of the N candidate networks is compared with a preset RSSI threshold, and a candidate network with the RSSI smaller than a second preset threshold of the wireless network is selected from the N candidate networks for connection.
It should be noted that the first preset threshold and the second preset threshold are both preset and are used for screening multiple candidate wireless networks, so as to select a wireless network selected to be matched for connection.
According to the multi-band switching method of the wireless network, the current Media Access Control (MAC) address of the currently connected wireless network is obtained, the MAC addresses and the Received Signal Strength Indication (RSSI) of the wireless networks in other frequency bands are scanned, and the matched wireless network is selected from the wireless networks for connection according to the current MAC address of the currently connected wireless network and the MAC addresses and the RSSI of the wireless networks in other frequency bands. According to the method, MAC addresses and RSSI of other frequency bands are scanned and matched with the MAC address of the currently connected wireless network, and then the matched wireless network is selected for connection, so that the technical problems that in the prior art, when the names of multi-frequency-band wireless networks are different, the networks cannot be automatically switched, and only manual network distribution can be carried out manually are solved, and the use experience of a user is improved.
As an example, this embodiment provides an interaction process of a multiband handover method of a wireless network, and fig. 2 is a schematic view of an interaction process of a multiband handover method of a wireless network provided in this embodiment.
As shown in fig. 2, the multiband handover method of the wireless network may include the steps of:
step 201, the terminal device detects the operation of opening the distribution network APP by the user.
In the embodiment of the application, after the terminal device for controlling the internet of things device to carry out the distribution network detects that the user opens the distribution network APP, the wireless network to be connected is displayed on the display interface of the terminal device.
In step 202, the terminal device detects the operation of selecting a wireless network of frequency band 1 and inputting a password.
And step 203, the terminal equipment sends the distribution network information selected by the user to the internet of things equipment.
Specifically, after the terminal device detects the operation of inputting the password into the wireless network with the frequency range 1 selected by the user, the terminal device sends the distribution network information such as the name and the password of the wireless network with the frequency range 1 selected by the user to the internet of things device.
And 204, connecting the Internet of things equipment to a wireless network router according to the received distribution network information sent by the terminal equipment.
Step 205, scanning the MAC address and RSSI of the wireless network of frequency band 2.
In the embodiment of the present application, the implementation process of step 205 is referred to step 102 in the above embodiment, and is not described herein again.
In step 206, the internet of things device determines whether the MAC address of the wireless network of the frequency band 2 matches the MAC address of the current wireless network according to the scanned MAC address of the wireless network of the frequency band 2.
In the embodiment of the application, the MAC address of the wireless network with the frequency band 2 is matched with the current MAC address of the wireless network with the currently connected frequency band 1, and the MAC address matching is performed when the first ten bits of the MAC address are the same.
As an example, if the MAC address of the currently connected wireless network of the frequency band 1 is AA: BB: CC: DD: EE: FF, the MAC address of the wireless network of the frequency band 2 is compared with the MAC address of the wireless network of the frequency band 1. If the MAC address of the wireless network of the frequency band 2 is the same as the first ten bits of the MAC address of the wireless network of the frequency band 1, the MAC address is matched; otherwise, the MAC addresses are not matched, and the wireless network of the frequency band 2 is not connected.
And step 207, judging whether the wireless network of the frequency band 2 is a matched wireless network according to the RSSI.
In the embodiment of the present application, when the MAC address of the wireless network of the frequency band 2 matches the MAC address of the wireless network of the frequency band 1, the RSSI obtained in step 205 is compared with the preset RSSI threshold, and if the RSSI is greater than the preset threshold, it is determined that the wireless network of the frequency band 2 is the matching wireless network, and step 208 is sequentially executed; otherwise, the wireless network of frequency band 2 is not connected.
And step 208, after the wireless network of the frequency band 2 is determined to be the matched wireless network, connecting the wireless network.
The multi-band switching method of the wireless network comprises the steps of scanning the MAC address and the received signal strength indication RSSI of the wireless network of the frequency band 2 by obtaining the MAC address of the wireless network of the frequency band 1, judging whether the wireless network of the frequency band 2 is matched with the MAC address of the current wireless network according to the scanned MAC address of the wireless network of the frequency band 2, further judging whether the wireless network of the frequency band 2 is a matched wireless network according to the RSSI when the wireless network of the frequency band 2 is matched with the MAC address of the current wireless network, and connecting the wireless network after the wireless network of the frequency band 2 is determined to be the matched wireless network. According to the method, the MAC address and the RSSI of the frequency band 2 are scanned and matched with the MAC address of the wireless network of the frequency band 1, and then connection is carried out when the wireless network of the frequency band 2 is determined to be matched, so that the technical problems that in the prior art, when the names of the multi-frequency-band wireless networks are different, the networks cannot be automatically switched, and manual network distribution can only be carried out manually are solved, and the use experience of a user is improved.
