Description

Technical Field

[0002] Wireless mesh network (wireless MESH network), also known as "multi-hop" network, is a new wireless network technology that is completely different from traditional wireless networks. It is a dynamic and continuously expandable network architecture, and any two devices can maintain wireless interconnection. With its multi-hop interconnection and mesh topology characteristics, it has evolved into an effective solution for a variety of wireless access networks such as broadband home networks, community networks, enterprise networks and metropolitan area networks.

[0003] Wireless mesh networks can use multiple frequency bands such as 2.4G, 5G, SUB6G, etc. for networking. In related technologies, in order to ensure that adjacent terminals communicate on the same frequency band, users generally manually configure the working frequency bands for all terminals in the network. For example, all terminals are configured to the same working frequency band, or adjacent terminals are configured to the same working frequency band based on the adjacent relationship of the terminals.

[0072] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0073] First, the application scenarios of the present disclosure will be described. The present disclosure can be applied to the terminal access scenario in the target network.

[0074] Figure 1 It is a schematic diagram of a target network to which a network access method provided by an embodiment of the present disclosure is applied. As Figure 1 shown, the target network can be a network including one or more terminals with wireless relay functions, such as a wireless mesh network. Exemplarily, the target network can include: a first terminal 101 that has accessed the target network, and a second terminal 102 that is to access the target network. Both the first terminal 101 and the second terminal 102 can support one or more frequency bands, for example, they can support one or more of the frequency bands such as 2.4G, 5G, and SUB6G. It should be noted that the terminals (including the first terminal and the second terminal) in the target network can be electronic devices such as routers, smart phones, tablets, smart watches, smart bracelets, PDAs (Personal Digital Assistants), and CPEs (Customer Premise Equipment), and the present disclosure does not limit this.

[0075] With the improvement of communication demand and the development of communication technology, there are more and more terminals in the target network, and the types of frequency bands supported by the terminals are also diverse. For example, the target network may include a single-band terminal, a dual-band terminal, a tri-band terminal, etc., wherein: the single-band terminal may include a radio frequency module, which may work in any one of the 2.4G or 5G bands; the dual-band terminal may include two radio frequency modules (for example, a 2.4G module and a 5G module), so that it may work in the 2.4G band and one of the 5G bands at the same time, but since the available bandwidth of 5G is large, it may be divided into multiple sub-bands (BAND1, BAND2, and BAND4), and the dual-band terminal may only work in one of the multiple sub-bands. For example, the user may set the dual-band terminal to work in the first sub-band (for example, BAND1), or the user may change the working band of the dual-band terminal, for example, from the first sub-band (for example, BAND2) to the second sub-band (for example, BAND4); the tri-band terminal may include three radio frequency modules (for example, a 2.4G module, a 5G_1 module, and a 5G_2 module), so that it may work in the 2.4G band and two sub-bands of 5G at the same time. For example, the 5G_1 module can operate in any frequency band of BAND1 or BAND2, and the 5G_2 module can operate in BAND4.

[0076] In the case where the frequency bands supported by the terminals in the target network are different, for example, there are dual-band terminals and tri-band terminals at the same time, since different terminals cannot obtain the frequency band support of each other's terminals, once adjacent terminals use different working frequency bands, the terminals will not be able to communicate. Therefore, in order to ensure that the second terminal can access the target network through the first terminal, the user generally manually configures the working frequency band of each terminal to ensure that the second terminal and the first terminal work in the same frequency band to achieve network access and data transmission. Moreover, in the later network maintenance, each new terminal needs to be manually configured, resulting in complex operation, low efficiency, and high network maintenance costs.

[0077] To solve the above problems, the present disclosure provides a network access method, apparatus, storage medium, and electronic device. A second terminal to be connected to a target network may send an access request beacon frame including one or more candidate frequency bands supported by the second terminal on each candidate frequency band, so that a first terminal already connected to the target network can obtain one or more candidate frequency bands supported by the second terminal, and thus can determine a target frequency band from the candidate frequency bands and send an access indication beacon frame to the second terminal on the target frequency band; the second terminal may respond to receiving the access indication beacon frame and access the target network through the target frequency band. In this way, it is possible to achieve automatic adaptation of each new terminal to use an appropriate target frequency band to access the target network without manually configuring the working frequency band of each terminal, improving the network maintenance efficiency and reducing the network maintenance cost.

[0078] The following describes the present disclosure in conjunction with specific embodiments.

[0079] Figure 2 This is a network access method provided by an embodiment of the present disclosure. As Figure 2 shown, the execution subject of this method may be a first terminal already connected to the target network, and this method includes:

[0080] S201. Receive an access request beacon frame sent by a second terminal.

[0081] Wherein, the access request beacon frame includes one or more candidate frequency bands supported by the second terminal. The second terminal may be a terminal to be connected to the target network.

[0082] In this step, the first terminal may periodically receive an access request beacon frame sent by the second terminal on the current working frequency band; or may respond to a device search instruction input by the user and receive an access request beacon frame sent by the second terminal on the current working frequency band or a non-working frequency band supported by the first terminal.

[0083] Exemplarily, the first terminal may receive a device search instruction input by the user to the first terminal through a web page, APP, etc. The device search instruction may be used to instruct the first terminal to search for or add unconnected terminals. At this time, the first terminal may start beacon frame monitoring on the current working frequency band or a non-working frequency band supported by the first terminal to receive an access request beacon frame sent by the second terminal.

[0084] S202. Determine a target frequency band from one or more of the candidate frequency bands according to the access request beacon frame.

[0085] In this step, the target frequency band may be determined by any one of the following multiple methods:

[0086] Method 1: Use the candidate frequency band on which the access request beacon frame is received as the target frequency band.

[0087] For example, when the candidate frequency band for receiving the access request beacon frame is the current working frequency band of the first terminal, the candidate frequency band can be used as the target frequency band to instruct the second terminal to access the target network through the target frequency band. For example, if the current working frequency band of the first terminal is the 5G_1 frequency band and the candidate frequency band for receiving the access request beacon frame is also the 5G_1 frequency band, the 5G_1 frequency band can be used as the target frequency band.

[0088] Method 2: Among one or more candidate frequency bands in the access request beacon frame, determine the candidate frequency band supported by the first terminal as the target frequency band.

[0089] For example, when the candidate frequency band for receiving the access request beacon is not the current working frequency band of the first terminal, it can be determined whether the candidate frequency band in the access request beacon includes the current working frequency band of the first terminal; if it includes, the current working frequency band of the first terminal can be used as the target frequency band; if it does not include, it can be further determined whether one or more candidate frequency bands include the idle and available frequency bands supported by the first terminal. If it includes, the idle and available frequency band can be used as the target frequency band.

[0090] Among them, the idle and available frequency band can indicate the frequency band on which the first terminal can work simultaneously outside the current working frequency band. For example, if the first terminal is a three-band terminal that can work on three frequency bands of 2.4G, 5G_1, and 5G_2 simultaneously, and the current working frequency band is 5G_1, then 5G_2 and 2.4G can be the idle and available frequency bands of the first terminal.

[0091] In this way, a suitable target frequency band can be determined according to the candidate frequency bands in the access request beacon frame and the frequency band situation supported by the first terminal, so as to instruct the second terminal to access the target network through the target frequency band.

[0092] S203: Send an access indication beacon frame to the second terminal through the target frequency band, so that the second terminal accesses the target network through the target frequency band in response to receiving the access indication beacon frame.

[0093] Among them, the target network is a network including one or more terminals with wireless relay functions. For example, it can be Figure 1 the target network shown. The access indication beacon frame is used to notify the second terminal to access the target network.

[0094] By adopting the above method, an access request beacon frame including one or more target frequency bands sent by a second terminal is received; according to the access request beacon frame, a target frequency band is determined from one or more candidate frequency bands; and an access indication beacon frame is sent to the second terminal through the target frequency band, so that the second terminal can access the target network through the target frequency band in response to receiving the access indication beacon frame. Thus, it is not necessary to manually configure the working frequency band of each terminal, and each new terminal can be automatically adapted to use a suitable target frequency band to access the target network, improving the network maintenance efficiency and reducing the network maintenance cost.

[0095] Figure 3 It is the second network access method provided by an embodiment of the present disclosure. As Figure 3 shown, the execution subject of this method may be a second terminal to be accessed to a target network, and this method includes:

[0096] S301. Send an access request beacon frame on each candidate frequency band supported by the second terminal.

[0097] The access request beacon frame includes one or more candidate frequency bands supported by the second terminal, so that after the first terminal that has accessed the target network receives the access request beacon frame, a target frequency band is determined from the one or more candidate frequency bands, and an access indication beacon frame is sent to the second terminal on the target frequency band.

[0098] Exemplarily, the second terminal may actively send the access request beacon frame after power-on; or may send the access request beacon frame after receiving a user input network access instruction, and the network access instruction may include: a pressing operation instruction input by the user on a preset network access button of the second terminal, a preset network access voice instruction issued by the user, and one or more of a preset network access gesture instructions issued by the user.

[0099] Further, in order to be able to access the target network more reliably, the second terminal may periodically send the access request beacon frame. The period for sending the access request beacon frame may be any time period between 10 ms and 5000 ms. For example, it may be 100 ms, 500 ms or 1000 ms.

[0100] S302. Respond to receiving the access indication beacon frame and access the target network through the target frequency band.

[0101] The target network is a network including one or more terminals with a wireless relay function. For example, it may be Figure 1 the target network shown.

[0102] Using the above method, the second terminal to be connected to the target network sends an access request beacon frame including one or more candidate frequency bands supported by the second terminal on each candidate frequency band, so that the first terminal already connected to the target network can obtain one or more candidate frequency bands supported by the second terminal, and thus can determine a target frequency band from the candidate frequency bands and send an access indication beacon frame to the second terminal on the target frequency band; in this way, the second terminal can access the target network through the target frequency band in response to receiving the access indication beacon frame. In this way, it is possible to achieve automatic adaptation of each new terminal to use a suitable target frequency band to access the target network without manually configuring the working frequency band of each terminal, improving the network maintenance efficiency and reducing the network maintenance cost.

[0103] Figure 4 This is the third network access method provided by the embodiments of the present disclosure. As Figure 4 shown, the method may include:

[0104] S401. The second terminal to be connected to the target network sends an access request beacon frame on each candidate frequency band supported by the second terminal.

[0105] Wherein, the access request beacon frame includes one or more candidate frequency bands supported by the second terminal.

[0106] It should be noted that in the related art, the access request beacon frame sent by the second terminal only contains an access request indication and does not contain the frequency band information supported by the terminal. Therefore, the first terminal receiving the access request indication cannot determine all the frequency band information supported by the second terminal, resulting in the inability to select a suitable target frequency band. In this embodiment, by including one or more candidate frequency bands supported by the second terminal in the access request beacon frame, the first terminal receiving the access request beacon frame can obtain the candidate frequency bands, and thus select a suitable target frequency band according to the candidate frequency bands.

[0107] Further, the above one or more candidate frequency bands may include one or more other frequency bands supported by the second terminal except the transmission frequency band for sending the access request beacon frame. This can reduce the frame length of the access request beacon frame and save the consumption of wireless network resources.

[0108] S402. After receiving the access request beacon frame, the first terminal already connected to the target network determines a target frequency band from the one or more candidate frequency bands.

[0109] In this step, if one or more candidate frequency bands sent by the second terminal are all the frequency bands supported by the second terminal, the target frequency band can be directly determined and selected from the one or more candidate frequency bands; if one or more candidate frequency bands sent by the second terminal can include one or more other frequency bands supported by the second terminal except the transmission frequency band for sending the access request beacon frame, the target frequency band can be determined and selected from the one or more candidate frequency bands and the reception frequency band for receiving the access request beacon frame.

[0110] In another embodiment of the present disclosure, the above access request beacon frame may further include a second terminal identifier of the second terminal; in this step, the first terminal may determine whether the second terminal is the target terminal to be accessed to the target network according to the target terminal identifier and the second terminal identifier, where the target terminal identifier is the identifier of the target terminal to be accessed to the target network input by the user; in the case of determining that the second terminal is the target terminal to be accessed to the target network, the target frequency band is determined from one or more of the candidate frequency bands.

[0111] Exemplarily, the target terminal identifier may be the identifier of the target terminal to be accessed to the target network input by the user through a key, voice, web client or APP client. In the case where the second terminal identifier is the same as the target terminal identifier, it can be determined that the second terminal is the target terminal to be accessed to the target network.

[0112] In this way, the access of legal terminals to the target network can be controlled according to the target terminal identifier input by the user, while other terminals not authorized by the user cannot access the target network, thereby avoiding the illegal access of unauthorized terminals and improving the security of the target network.

[0113] Furthermore, the above target terminal identifier can also be obtained in the following manner:

[0114] First, in response to the device search instruction input by the user, the first terminal scans the candidate terminals not connected to the network in the target network, and displays the candidate terminal identifiers of the candidate terminals to the user, so that the user can select and determine the target terminal identifier to be accessed to the target network according to the candidate terminal identifier.

[0115] Then, the first terminal obtains the target terminal identifier selected by the user according to the candidate terminal identifier.

[0116] In this way, it can be made convenient for the user to obtain which terminals in the target network are not connected to the network, so as to facilitate the user to select the target terminal among them to access the target network.

[0117] In another embodiment of the present disclosure, in the case where multiple received access request beacon frames are involved, in this step, any one of the multiple access request beacon frames can be used as a candidate access beacon frame; based on the candidate access beacon frame, a target frequency band is determined from one or more of the candidate frequency bands.

[0118] It should be noted that if multiple access request beacon frames sent by the second terminal are received simultaneously, one of them can be randomly selected as the candidate access beacon frame; if multiple access request beacon frames sent by the second terminal are received at different times, the first received access request beacon frame can be used as the candidate access beacon frame, and the subsequently received access request beacon frames are ignored.

[0119] In this way, it is possible to prevent the second terminal from initiating access procedures simultaneously on multiple frequency bands, avoid access procedure conflicts, and also save network resources.

[0120] S403. The first terminal sends an access indication beacon frame to the second terminal on the target frequency band.

[0121] S404. In response to receiving the access indication beacon frame, the second terminal accesses the target network through the target frequency band.

[0122] Using the above method, the second terminal waiting to access the target network sends an access request beacon frame including one or more candidate frequency bands supported by the second terminal on each candidate frequency band; the first terminal that has accessed the target network can obtain one or more candidate frequency bands supported by the second terminal based on the received access request beacon frame, determine a target frequency band from the candidate frequency bands, and send an access indication beacon frame to the second terminal on the target frequency band; in this way, the second terminal can access the target network through the target frequency band in response to receiving the access indication beacon frame. In this way, it is not necessary to manually configure the working frequency band of each terminal, that is, each new terminal can automatically adapt to use an appropriate target frequency band to access the target network, improving network maintenance efficiency and reducing network maintenance costs.

[0123] In another embodiment of the present disclosure, the second terminal accessing the target network through the target frequency band in the above S404 step may include the following steps:

[0124] First, the second terminal performs security authentication with the first terminal through the target frequency band.

[0125] The security authentication can be WPS (Wi-Fi Protected Setup) or other security authentication methods. WPS is a wireless network security standard designed to simplify the encryption steps when home users use wireless networks. WPS can help users automatically set the network name, configure the powerful WPA (Wi-Fi Protected Access) data encoding and authentication functions. Users only need to enter a personal information code or press a preset authentication button to perform security authentication and securely access the target network, thus greatly simplifying the operation of wireless security settings and further improving the security of the target network through security authentication.

[0126] Secondly, when the security authentication of the second terminal is successful, the second terminal receives the network configuration message sent by the first terminal through the target frequency band.

[0127] The network configuration message may include the working frequency band, working frequency point, bandwidth, encryption information, etc. of the wireless channel.

[0128] Thirdly, the second terminal sets the network parameters of the second terminal according to the network configuration message and sends an access success message to the first terminal in the target frequency band to indicate that the second terminal has successfully accessed.

[0129] Finally, after receiving the access success message of the second terminal, the first terminal may store the second terminal identifier of the second terminal.

[0130] In this way, when the first terminal receives the access request beacon frame of the second terminal, it can determine whether the access request beacon frame is a repeated access request according to the second terminal identifier, thereby avoiding process conflicts and resource waste caused by repeated access.

[0131] In another embodiment of the present disclosure, when the first terminal changes the frequency band due to reasons such as user setting changes, it can be performed in the following manner:

[0132] First, when the first terminal determines that a frequency band change is required, it sends a frequency band change message to the second terminal.

[0133] Among them, the frequency band change message includes the first target change frequency band to be changed and the target change time. The first target change frequency band can be a change frequency band specified by the user; it can also be determined according to the candidate frequency bands supported by all terminals adjacent to the first terminal in the target network. It should be noted that when the second terminal successfully accesses the target network, the first terminal can also store all candidate frequency bands supported by the second terminal. In this way, the first terminal can store the candidate frequency bands supported by each terminal that has accessed the target network and is adjacent to the first terminal.

[0134] It should be noted that the methods for the first terminal to determine the need for frequency band change can include any of the following:

[0135] Method 1: Determine the need for frequency band change according to the frequency band change instruction input by the user, and determine the first target change frequency band.

[0136] Method 2: Determine the need for frequency band change according to DFS (Dynamic Frequency Selection), and determine the first target change frequency band. Among them, DFS is a channel allocation scheme, and the device dynamically selects or changes the operating frequency or operating frequency band through the DFS function to avoid interference to other systems, especially radar systems, or to avoid interference from other systems to itself.

[0137] Then, the second terminal receives the frequency band change message sent by the first terminal, and according to the target change time, changes the target frequency band to the first target change frequency band, and re-accesses the target network on the changed target frequency band.

[0138] In this way, through the frequency band change message, the first terminal and the second terminal can change to the first target change frequency band at the same time at the target change time for communication, thereby avoiding data transmission failure during frequency band change and improving the reliability of data transmission in the target network.

[0139] Furthermore, the second terminal can also periodically determine whether the communication link with the first terminal fails; in the case of determining that the communication link with the first terminal fails, determine a candidate frequency band different from the target frequency band from the candidate frequency bands as the second target change frequency band; change the target frequency band to the second target change frequency band, and re-access the target network on the changed target frequency band.

[0140] Exemplarily, the second terminal can periodically send a heartbeat request message to the first terminal and receive the heartbeat response message sent by the first terminal. If the heartbeat response message is not received within the preset time, it can be determined that the communication link with the first terminal fails.

[0141] Furthermore, there can be multiple second target change frequency bands, for example, all candidate frequency bands different from the current operating frequency band among the candidate frequency bands supported by the second terminal. In this way, the second terminal can poll and attempt to access the target network among multiple second target change frequency bands.

[0142] In this way, in the case of a communication link failure, the second terminal can re-access the target network by changing the frequency band, avoiding long-term service interruption, and further improving the reliability of data transmission in the target network.

[0143] Figure 5This is the fourth network access method provided by the embodiments of the present disclosure. As Figure 5 shown, the method may include:

[0144] S501. The second terminal to be connected to the target network sends an access request beacon frame on each candidate frequency band supported by the second terminal.

[0145] Wherein, the access request beacon frame includes one or more candidate frequency bands supported by the second terminal.

[0146] S502. In response to receiving a user instruction, the client sends a device search instruction to the first terminal that has been connected to the target network.

[0147] Wherein, the client may be a web client or an APP client.

[0148] S503. In response to the device search instruction, the first terminal scans one or more candidate terminals not connected to the target network in the target network, and sends the candidate terminal identifier of the candidate terminal to the client.

[0149] S504. The client displays the received one or more candidate terminal identifiers to the user, so that the user can select one of the candidate terminals as the target terminal to be connected to the network and access the target network.

[0150] S505. The client sends the candidate terminal identifier selected by the user to the first terminal.

[0151] S506. When the received candidate terminal identifier is the terminal identifier of the second terminal, the first terminal may create a virtual access point (VAP, Virtual Access Point) for the second terminal and enable security authentication.

[0152] Wherein, the security authentication may be WPS (Wi-Fi Protected Setup, WiFi protected setup) or other security authentication methods. The virtual access point is used for data communication with the second terminal, so that the second terminal can access the target network without affecting the normal communication of other terminals in the target network. A VAP is to virtualize multiple APs on a physical entity AP, and each virtualized AP is a VAP, and each VAP provides the same functions as the physical entity AP.

[0153] S507. The first terminal determines a target frequency band from the above one or more candidate frequency bands, and sends an access indication beacon frame to the second terminal on the target frequency band.

[0154] S508. The second terminal listens to each candidate frequency band, and when receiving the access indication beacon frame on any one of the candidate frequency bands, uses the candidate frequency band as the target frequency band.

[0155] S509. The second terminal enables the security authentication function and performs security authentication with the first terminal through the target frequency band.

[0156] S510. When the first terminal determines that the security authentication of the second terminal is successful, it sends a network configuration message to the first terminal through the target frequency band.

[0157] The network configuration message may include the operating frequency band, operating frequency point, bandwidth, encryption information, etc. of the wireless channel.

[0158] S511. The second terminal sets the network parameters of the second terminal according to the received network configuration message and sends an access success message to the first terminal in the target frequency band to indicate that the second terminal has successfully accessed.

[0159] S512. After receiving the access success message of the second terminal, the first terminal may store the second terminal identifier of the second terminal.

[0160] It should be noted that if the access request beacon frame of the second terminal includes multiple candidate frequency bands and different candidate frequency bands correspond to different BSSIDs (Basic Service Set Identifier, terminal device identifier), the first terminal may store multiple BSSIDs corresponding to the second terminal. As long as any one of the BSSIDs accesses successfully, it can be confirmed that the second terminal has successfully accessed.

[0161] By adopting the above method, it is not necessary to manually configure the operating frequency band of each terminal, that is, each new terminal can be automatically adapted to use a suitable target frequency band to access the target network, improving the network maintenance efficiency and reducing the network maintenance cost.
