Description

Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a communication method, a routing device, a terminal and a medium. Background Art

[0002] Terminals can transmit information by connecting to routers. Current routers can support multi-band connections, but the number of terminals that can be connected to each band is limited. When the band is fully connected, the process of the terminal accessing the band will fail, thus affecting the user's network experience.

[0003] Therefore, when a certain frequency band of the router is fully connected, how to encourage the terminal to access other frequency bands to ensure a good network experience for users is an urgent problem to be solved. Summary of the invention

[0004] The present application provides a communication method, a routing device, a terminal and a medium. The method can guide the terminal to select a wireless access point (AP) with an unfilled frequency band, thereby ensuring a good user experience for the user.

[0005] A first aspect provides a communication method, which is applied to a routing device, wherein the routing device includes at least two frequency bands, and the method includes: sending at least two messages, wherein the message is used for a terminal to discover the routing device, wherein the at least two messages include a first message and a second message, the at least two frequency bands include a first frequency band and a second frequency band, the first message corresponds to the first frequency band, the second message corresponds to the second frequency band, and the at least two messages include a first field, the first field of the first message is used to indicate that the number of access point access terminals in the first frequency band has not reached a first threshold, and the first field of the second message is used to indicate that the number of access point access terminals in the second frequency band has reached a second threshold.

[0006] It should be noted that the number of access point access terminals in the first frequency band and the number of access point access terminals in the second frequency band are limited. The maximum number of access point access terminals in the first frequency band is the first threshold, and the maximum number of access point access terminals in the second frequency band is the second threshold. The first threshold and the second threshold may be the same or different. For example, the first threshold and the second threshold are 32. It can be understood that when the number of access point terminals in the first frequency band does not reach the first threshold, it indicates that the first frequency band is not fully connected; when the number of access point access terminals in the second frequency band has reached the second threshold, it indicates that the second frequency band is fully connected.

[0007] Exemplarily, the routing device may support a multi-band router that is preferred for the 5 GHz frequency band. The message may be a Beacon message sent by the routing device in a broadcast manner, the number of access point access terminals in the second frequency band has reached the maximum number, the second frequency band is a fully connected 5 GHz frequency band, the number of access point access terminals in the first frequency band has not reached the maximum number, the first frequency band is an incompletely connected 2.4 GHz frequency band. The first field is an information element (IE) field, and the routing device may add an IE field in the Beacon message to indicate whether the AP that sends the Beacon message can be connected. When the first field of the first message indicates that the number of access point access terminals in the first frequency band has not reached the maximum number, it indicates that the AP in the first frequency band can be connected; when the first field of the second message indicates that the number of access point access terminals in the second frequency band has reached the maximum number, it indicates that the AP in the second frequency band cannot be connected.

[0008] It should be noted that APs of multiple frequency bands of the routing device can send messages. The first message is sent by the AP of the first frequency band of the routing device, and the second message is sent by the AP of the second frequency band of the routing device. Exemplarily, the AP of the 2.4 GHz frequency band sends the first message, and the AP of the 5 GHz frequency band sends the second message.

[0009] Based on the above solution, the routing device (router) can add a field in the message to indicate whether the AP sending the message can be connected. When the number of access terminals of a certain frequency band of the multi-frequency router has reached the maximum number, by adding a field in the message, the terminal is guided to find the frequency band where the number of other access terminals has not reached the maximum number, thereby increasing the possibility of the terminal successfully accessing APs of other frequency bands in the future and ensuring a good network experience for users.

[0010] In combination with the first aspect, in certain implementations of the first aspect, before sending the at least two messages, the method further includes: reducing the signal quality of the second message.

[0011] Based on the above solution, when the number of terminals accessing a certain AP has reached the maximum number, the signal quality of the message sent by the AP is reduced, thereby reducing the possibility of the terminal discovering the AP. At this time, the possibility of the terminal discovering other APs will be relatively increased, thereby guiding the terminal to access other APs and ensuring the user's network experience.

[0012] In combination with the first aspect, in certain implementations of the first aspect, before sending the at least two messages, the method also includes: increasing the sending period of the second message; wherein, sending the at least two messages includes: sending the first message with a first period, and sending the second message with a second period, and the second period is greater than the first period.

[0013] Based on the above scheme, increasing the period of the second message sent by the AP in the full frequency band can reduce the possibility of the terminal discovering the AP. At this time, the possibility of the terminal discovering other APs will be relatively increased, thereby guiding the terminal to access other APs and ensuring the user's network experience.

[0014] In combination with the first aspect, in some implementations of the first aspect, the network name SSID of the first frequency band is the same as the network name SSID of the second frequency band.

[0015] In combination with the first aspect, in some implementations of the first aspect, the message is a Beacon message.

[0016] The second aspect provides a communication method, which is applied to a routing device, and the routing device includes at least two frequency bands. The method includes: receiving a request message from a terminal; sending a first message, and not sending a second message; wherein the at least two frequency bands include a first frequency band and a second frequency band, the first message is a response message to the request message, the second message is a response message to the request message, the first message corresponds to the first frequency band, the second message corresponds to the second frequency band, the at least two frequency bands include the first frequency band and the second frequency band, the number of access points and access terminals in the first frequency band has not reached a first threshold, and the number of access points and access terminals in the second frequency band has reached a second threshold.

[0017] It should be noted that the first threshold is the maximum number of access terminals of the access point in the first frequency band, and the second threshold is the maximum number of access terminals of the access point in the second frequency band.

[0018] Exemplarily, the request message is a Probe Request message, and the first message and the second message are Probe Response messages. The first message is a message sent by the routing device through an AP of a first frequency band, and the second message is a message sent by the routing device through an AP of a second frequency band.

[0019] For example, when the 5 GHz band is fully connected, the AP in the 5 GHz band does not send Probe Response messages; when the 2.4 GHz band is not fully connected, the AP in the 2.4 GHz band can send Probe Response messages.

[0020] Based on the above solution, after receiving the request message from the terminal, the routing device does not send the Probe Response message through the AP whose number of access terminals has reached the maximum number, but can send the Probe Response message through the AP whose number of access terminals has not reached the maximum number, so that after the terminal receives the Probe Response message sent by the AP whose number of access terminals has not reached the maximum number, it can initiate a connection to the AP whose number of access terminals has not reached the maximum number, thereby increasing the possibility of the terminal successfully accessing the routing device and ensuring a good network experience for users.

[0021] In combination with the second aspect, in certain implementations of the second aspect, before sending the first message, the method also includes: adding a first field in the first message, the first field in the first message being used to indicate that the number of access terminals in the first frequency band has not reached a first threshold.

[0022] Exemplarily, the first field is an IE field. The routing device may add an IE field to the Probe Response message to indicate whether the AP sending the Probe Response message can be connected.

[0023] Based on the above solution, the routing device can add a field in the Probe Response message to indicate whether the AP sending the message is connectable, and guide the terminal to connect to the AP whose number of access terminals does not reach the maximum number, thereby ensuring a good network experience for users.

[0024] In combination with the second aspect, in some implementations of the second aspect, the request message is a broadcast message, and the first message is a unicast message.

[0025] In combination with the second aspect, in some implementations of the second aspect, the network name SSID of the first frequency band is the same as the network name SSID of the second frequency band.

[0028] It should be noted that the first threshold is the maximum number of access terminals of the access point in the first frequency band; the second threshold is the maximum number of access terminals of the access point in the second frequency band.

[0029] Exemplarily, the terminal receives a Beacon message from a routing device. The Beacon message includes an IE field. The terminal receives a first message sent from an AP of a first frequency band of the routing device, and receives a second message sent from an AP of a second frequency band of the routing device.

[0030] Based on the above solution, the terminal receives messages sent by APs of multiple frequency bands from the routing device, determines the frequency band where a connection can be initiated based on the messages, and initiates a connection to the frequency band, ensuring that the terminal can successfully access the routing device and ensuring a good network experience for the user.

[0031] In combination with the third aspect, in certain implementations of the third aspect, a signal quality of the second message is lower than a signal quality of the first message.

[0032] Based on the above scheme, the signal quality of the messages received by the terminal from different frequency bands of the routing device may also be different. The terminal can not only determine whether the AP sending the message is connectable based on the fields in the message, but also determine whether to initiate a connection to the AP based on the signal quality of the message.

[0033] In combination with the third aspect, in certain implementations of the third aspect, a sending period of the second message is greater than a sending period of the first message.

[0034] Based on the above scheme, the terminal can also determine whether to initiate a connection to the AP according to the message sending period. That is, the terminal can select an AP whose number of access terminals does not reach the maximum number according to the fields in the message, the signal quality of the message and / or the message sending period, and initiate a connection to the AP, thereby increasing the possibility of successfully accessing the routing device and ensuring a good network experience for users.

[0035] In combination with the third aspect, in certain implementations of the third aspect, when the terminal supports parsing the first field, before initiating a connection to the first frequency band based on the at least two messages, the method also includes: parsing the at least two messages, determining that the number of access point access terminals in the first frequency band has not reached a first threshold, and the number of access point access terminals in the second frequency band has reached a second threshold.

[0036] Based on the above solution, when the terminal supports IE parsing, it can parse the message received from the routing device, and determine the accessible AP according to the parsing result, so as to initiate a connection to the AP, thereby improving the user's network experience.

[0037] In combination with the third aspect, in certain implementations of the third aspect, the network name SSID of the first frequency band is the same as the network name SSID of the second frequency band.

[0038] In combination with the third aspect, in some implementations of the third aspect, the message is a Beacon message.

[0040] It should be noted that the first threshold is the maximum number of access points and access terminals in the first frequency band; the second threshold is the maximum number of access points and access terminals in the second frequency band.

[0041] Exemplarily, the request message is a Probe Request message, and the first message and the second message are Probe Response messages. The terminal receives a first message sent by an AP of a first frequency band from a routing device.

[0042] Based on the above solution, after the terminal sends a request message to the routing device, it will only receive a response message from the AP whose number of terminals connected to the routing device has not reached the maximum number. Based on the response message, the terminal can initiate a connection to the AP of the frequency band that sent the response message, thereby increasing the possibility of the terminal successfully accessing the routing device and ensuring a good network experience for users.

[0107] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element converts the optical signal into an electrical signal, which is then transmitted to the ISP for conversion into a digital image signal.

The layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer. The application layer can include a series of application packages.

[0133] Before introducing the technical solution of the present application, some professional terms that may be involved in the present application are briefly introduced.

[0134] Routing Devices

[0135] A hardware device used to perform "routing". "Routing" refers to the action or behavior of data transmission. Routing devices act as gateways between networks and can determine the best path for network communications to pass through. Routing devices can understand different protocols, such as Ethernet protocol and transmission control protocol / internet protocol (TCP / IP) protocol. Routing devices can store and forward packets between different networks. It should be understood that routing devices in this article include routers (e.g., home routers, enterprise routers) and customer premise equipment (CPE). The following description takes the routing device as a router and the terminal as a mobile phone as an example.

[0136] Service set identifier (SSID)

[0137] The SSID of the router is the network name of the wireless network. SSID technology can divide a wireless LAN into multiple sub-networks that require different authentications. Each sub-network requires independent authentication. Only users who pass the authentication can enter the corresponding sub-network, preventing unauthorized users from entering the network.

[0138] Beacon message

[0139] The router can broadcast Beacon messages at a certain period. The Beacon messages include SSID and can be discovered by the terminal. The terminal can be understood as having Figure 1 As shown or Figure 2 Devices with the structure shown, for example, mobile phones, smart watches, etc.

[0140] like Figure 3 , a schematic diagram showing an applicable scenario of a communication method provided by an embodiment of the present application is shown. The method is applicable to the access process between a terminal and a router.

[0141] Currently, routers include 2.4GHz band, 5GHz band and even more bands. The Wi-Fi signal of the 2.4GHz band has strong wall penetration ability, but it is easily interfered with, resulting in unstable Internet access experience. It is suitable for terminals such as mobile phones and tablets that need to move frequently between rooms. Frequently moving terminals can take advantage of the strong wall penetration ability of the 2.4GHz band to ensure that mobile terminals such as mobile phones and tablets can access the Internet normally in every room. The Wi-Fi signal of the 5GHz band has a fast transmission speed and is not easily interfered with, but it has weak wall penetration ability. Generally, the Wi-Fi signal of the 5GHz band will become weak after passing through a wall. It is suitable for devices that are in the same room as the router and do not require high wall penetration ability. Take advantage of the fast speed and strong anti-interference ability of the Wi-Fi signal of the 5GHz band to ensure that the device has a faster and more stable user experience.

[0142] The router can support 5GHz band preference. In the scenario of 5GHz band preference, the SSID of 2.4GHz band and 5GHz band are the same by default, and the terminal is preferentially connected to the router of 5GHz band. Generally speaking, the number of devices that can be accessed by each band of the router is limited. For example, the maximum number of access terminals of the access point (AP) of the 2.4GHz band is 32 devices, and the maximum number of access terminals of the AP of the 5GHz band is 32 devices. For a dual-band router that supports 5GHz band preference, the maximum number of access terminals is 64 devices, and in the Wi-Fi configuration interface of the device, the SSID of 2.4GHz band and 5GHz band is the same. When a user establishes a connection with a certain band of the router through the Wi-Fi configuration interface, since it is unclear whether the number of access terminals of the AP of the band has reached the maximum number of access terminals, there may be access failures, thereby affecting the user experience.

[0143] For ease of understanding, Figure 4 As shown, a set of graphical user interfaces (GUIs) is shown, and a mobile phone is taken as an example to introduce the main process of a user sending an access request to a router through the user interface.

[0144] like Figure 4 As shown in (a) of FIG. 4 , the setting interface of the mobile phone is shown. The setting interface displays multiple options, wherein the multiple options include wireless LAN, Bluetooth, display and sound options. In response to the user's operation on the wireless LAN option 401, the mobile phone displays the following Figure 4 GUI shown in (b).

[0145] like Figure 4As shown in (b), in response to the user's operation on the wireless LAN option 401, the mobile phone displays the wireless LAN interface. The wireless LAN displays a wireless LAN control 402. Among them, the control is a visual graphical interface element presented to the user. It is a software component included in the application, which controls the data processed by the application and the interactive operations on these data. The user can interact with the control through touch, slide and other operations to read and edit the relevant information of the application. In general, the control may include icons, buttons, menus, tabs, text boxes, status bars and other visual interface elements. In response to the user's operation on different controls (for example: touch operation, or click operation), different interfaces may be displayed on the screen of the device or different functions may be triggered. In response to the user clicking the wireless LAN control 402, the mobile phone can turn on the function of connecting to the wireless LAN. The wireless LAN interface also includes the network names of each wireless LAN within the communication range of the mobile phone. Figure 4 The wireless LAN interface shown in (b) also includes a network name option, wherein the network name option includes an "ID123" option 403. It can be seen that the mobile phone user cannot determine the specific frequency band of the router corresponding to the network name from the network name displayed on the wireless LAN interface. In other words, from the user's perspective, the APs corresponding to multiple frequency bands of the router that supports the 5GHz frequency band preference only display the same network name on the user interface, and the user cannot distinguish them. In response to the user's operation on the "ID123" option 403, the mobile phone displays something like Figure 4 GUI shown in (c) in FIG.

[0146] like Figure 4 As shown in (c) of FIG. 1 , in response to the user's operation on the "ID123" option 403, the wireless LAN interface of the mobile phone displays a prompt message 404. The prompt message 404 is used to prompt the user to enter the password of "ID123". When the user completes the input of the "ID123" password, the mobile phone may display the following Figure 4 GUI shown in (d).

[0147] like Figure 4 As shown in (d) in FIG. 1 , in response to the user completing the input of the "ID123" password, the wireless LAN interface of the mobile phone displays a prompt message 405. The prompt message 405 is used to prompt that the mobile phone fails to connect to the "ID123" wireless LAN.

[0148] It should be noted that the wireless LAN interface of a mobile phone can be understood as the Wi-Fi configuration interface.

[0149] Exemplarily, the "ID123" option 403 corresponds to multiple frequency bands of a router that supports 5GHz frequency band preference, and the multiple frequency bands can be 5GHz frequency bands or 2.4GHz frequency bands. The user cannot distinguish which frequency band is to be accessed through the user interface, but because the router supports 5GHz frequency band preference, the number of AP access terminals in the 5GHz frequency band of the router has reached the second threshold. Even if the user enters the password correctly, it is obviously possible that the terminal fails to access the router. Alternatively, the mobile phone has successfully accessed the 5GHz frequency band and the 2.4GHz frequency band of the router. When the mobile phone needs to access the router again, it is not necessary to enter the password. The router sets the mobile phone to give priority to accessing the 5GHz frequency band. When the number of 5GHz AP access terminals has reached the second threshold, access failure may also occur. The user's failure to access the router will affect the user's subsequent network experience. Among them, the second threshold can be understood as the maximum number of AP access terminals in the 5GHz frequency band of the router.

[0150] Based on this, the embodiment of the present application provides a communication method, a routing device, a terminal and a medium. The method is applicable to a routing device supporting multiple frequency bands. When the number of AP access terminals of a certain frequency band of the routing device has reached the maximum number, the routing device can guide the terminal to access other APs whose number of access terminals has not reached the maximum number, so that the terminal can smoothly establish a communication connection with the router, which is convenient for users to use the network.

[0151] It should be noted that in the process of establishing a communication connection through Wi-Fi, the terminal needs to discover the existence of wireless fidelity (Wi-Fi) (or router). Among them, the process of the terminal discovering the existence of the router can be understood as scanning, and the scanning can include active scanning and passive scanning. It can be understood that the communication method provided in the embodiment of the present application can be applied to the scanning stage between the terminal and the router.

[0152] For example, during passive scanning, the terminal is in a receiving state, scanning available wireless channels. The terminal can receive Beacon messages sent by different APs. It is understandable that a router can include multiple APs, for example, one AP for each frequency band, and each AP has an identifier for user identification, such as SSID. For a multi-band router that supports the preferred 5GHz frequency band, the AP identifiers corresponding to multiple frequency bands of the router are the same, and the Beacon message can carry the SSID.

[0153] For another example, during active scanning, the terminal actively sends a Probe Request message and waits for an AP within the communication range of the terminal to respond with a Probe Response message.

[0154] Based on this, the communication method provided by the embodiments of the present application in passive scanning and active scanning scenarios are introduced below respectively.

[0155] like Figure 5 As shown, a communication method provided in an embodiment of the present application is shown. The method can be applicable to a communication system in a passive scanning scenario. The following takes the communication system including a router and a mobile phone as an example to introduce the communication method provided in the present application.

[0156] S501: The router determines the Beacon message.

[0157] It should be noted that the Beacon message may include the SSIDs of APs corresponding to multiple frequency bands of the router. It is understandable that the SSIDs of APs corresponding to multiple frequency bands of the router are the same.

[0158] In one implementation, an information element (IE) field may be added to the Beacon message, and the IE field is used to indicate whether the AP that sends the Beacon message can be connected.

[0159] For example, a multi-band router includes a 2.4GHz band and a 5GHz band. The AP corresponding to the 2.4GHz band sends Beacon message 1, in which an IE field can be added, and the IE field in Beacon message 1 is used to indicate whether the 2.4GHz band can be connected; the AP corresponding to the 5GHz band sends Beacon message 2, in which an IE field can be added, and the IE field in Beacon message 2 is used to indicate whether the 5GHz band can be connected.

[0160] It can be understood that if the current AP can be connected, it means that the number of access terminals in the frequency band corresponding to the current AP has not reached the maximum access number; if the current AP cannot be connected, it means that the number of access terminals in the frequency band corresponding to the current AP has reached the maximum number. For example, when the number of AP access terminals in the 5GHz band has reached the second threshold, the IE field in Beacon message 2 indicates that the AP corresponding to the 5GHz band cannot be connected; when the number of AP access terminals in the 2.4GHz band has not reached the first threshold, the IE field in Beacon message 1 indicates that the AP corresponding to the 2.4GHz band can be connected. It should be understood that the first threshold and the second threshold can be the same or different. The first threshold is the maximum number of AP access terminals in the 2.4GHz band, and the second threshold is the maximum number of AP access terminals in the 5GHz band. It should be noted that when the number of AP access terminals has reached the maximum number, it means that the frequency band corresponding to the AP is fully connected; when the number of AP access terminals has not yet reached the maximum number, it means that the frequency band corresponding to the AP is not fully connected.

[0161] In one implementation, when the number of terminals accessing a certain AP has reached the maximum number of access terminals, the signal quality of the AP's Beacon message can be reduced. The Beacon message with reduced signal quality will reduce the possibility of the terminal scanning (or discovering) the AP. At this time, the possibility of the terminal initiating a connection to other APs (with the same SSID as the current AP) increases.

[0162] In one implementation, Beacon messages are sent by broadcasting. Therefore, when the number of terminals accessing a certain AP has reached the maximum number of access terminals, the period of sending Beacon messages for the AP can be increased. Increasing the period of sending Beacon messages will reduce the possibility of terminals scanning (or discovering) the AP. At this time, the possibility of the terminal initiating a connection to other APs (with the same SSID as the current AP) increases.

[0163] S502: The router sends a Beacon message, and correspondingly, the mobile phone receives the Beacon message.

[0164] Exemplarily, the router sends Beacon messages at a certain period, wherein the Beacon messages may be sent in a broadcasting manner. The mobile phone may be one of a plurality of terminals within the communication range of the router.

[0165] According to the introduction of step S501 above, the router can adjust the sending period of Beacon messages according to whether the number of terminals accessing the AP has reached the maximum number of accesses. When the number of terminals accessing the current AP has reached the maximum number of accesses, the period of the AP broadcast message can be increased to reduce the possibility of the terminal scanning the AP. At this time, the possibility of the terminal initiating a connection to other APs, especially to the AP with the same SSID as the current AP, increases.

[0166] For example, when the number of AP access terminals in the 5 GHz band has reached the second threshold, the AP can increase the period of broadcasting Beacon message 2. Of course, when the number of AP access terminals in the 2.4 GHz band has reached the first threshold, the AP can increase the period of broadcasting Beacon message 1.

[0167] It is understandable that in the above step S501, an IE field can be added to the Beacon broadcast message of the router. The terminal can determine whether the AP that sends the Beacon message broadcast message can be connected through the IE field in the Beacon message broadcast message, but not all terminals can support IE parsing. Based on this, the communication method provided in the embodiment of the present application can be applied to the following scenarios:

[0168] Scenario 1: The mobile phone supports IE parsing.

[0169] S503, the mobile phone parses the Beacon message.

[0170] It should be noted that the mobile phone can receive Beacon messages broadcast from APs in multiple frequency bands of the router. When the mobile phone supports IE parsing, it can parse the IE field in the Beacon message to determine whether the AP that sent the message can be connected.

[0171] For example, a router that supports multiple frequencies includes the 2.4GHz band and the 5GHz band. The mobile phone determines that the number of AP access terminals in the 5GHz band has reached the second threshold by parsing Beacon message 2 broadcast by the AP in the 5GHz band, indicating that the AP in the 5GHz band cannot be connected; or, the mobile phone determines that the 2.4GHz band is not fully connected by parsing Beacon message 1 broadcast by the AP in the 2.4GHz band, indicating that the AP in the 2.4GHz band can be connected.

[0172] S504, the mobile phone initiates a connection according to the parsed Beacon message.

[0173] Exemplarily, when the mobile phone parses the IE field in the message and determines that the number of AP access terminals in the 5 GHz band has reached the second threshold and the number of AP access terminals in the 2.4 GHz band has not reached the first threshold, the mobile phone can initiate a connection to the AP in the 2.4 GHz band.

[0174] It should be noted that when the mobile phone determines that a certain AP can be connected by parsing the Beacon message, it will further initiate a connection with the AP. The mobile phone can complete the access process through the authentication and association process with the AP.

[0175] For example, when the mobile phone parses the Beacon message and determines that the AP in the 2.4 GHz frequency band can be connected, the mobile phone can send an authentication request, an association request, etc. to the AP corresponding to the 2.4 GHz frequency band to complete the access process of the mobile phone and the AP.

[0176] Scenario 2: The mobile phone does not support IE parsing.

[0177] S505, the mobile phone initiates a connection according to the Beacon message.

[0178] It should be noted that for mobile phones that do not support IE parsing, it is impossible to determine whether the number of AP access terminals in a certain frequency band has reached the maximum number of access terminals based on the Beacon message broadcast by the router. However, the mobile phone can initiate a connection based on other information in the Beacon message.

[0179] In one implementation, the mobile phone initiates a connection according to a Beacon message sending cycle.

[0180] For example, the router increases the sending period of Beacon messages sent by APs in the 5 GHz band, and the possibility that the mobile phone discovers or scans Beacon messages sent by APs in the 5 GHz band decreases. Correspondingly, the possibility that the mobile phone discovers or scans Beacon messages sent by APs in the 2.4 GHz band increases. Therefore, the mobile phone selects the AP in the 2.4 GHz band to initiate a connection.

[0181] In one implementation, the mobile phone initiates a connection based on the signal quality of the Beacon message.

[0182] For example, the router reduces the signal quality of the Beacon message sent by the AP in the 5 GHz band, and the possibility of the mobile phone discovering or scanning the Beacon message sent by the AP in the 5 GHz band decreases. Correspondingly, the possibility of the mobile phone discovering or scanning the Beacon message sent by the AP in the 2.4 GHz band increases. Therefore, the mobile phone selects the AP in the 2.4 GHz band to initiate a connection.

[0183] It should be noted that the mobile phone can initiate a connection based on the Beacon message sending cycle and signal quality.

[0184] In other words, the sending period and signal quality of Beacon messages affect the possibility of mobile phones discovering or scanning APs. By adjusting the sending period and signal quality of Beacon messages, the mobile phone is guided to select an AP whose number of access terminals has not reached the maximum number, thereby guiding the mobile phone to access the AP.

[0185] like Figure 6 As shown, a communication method provided in an embodiment of the present application is shown. The method can be applicable to a communication system in an active scanning scenario. The communication method provided in the present application is introduced below by taking the communication system including a router and a mobile phone as an example.

[0186] S601: The mobile phone sends a Probe Request message, and correspondingly, the router receives the Probe Request message.

[0187] It should be noted that the mobile phone can send the Probe Request message in broadcast mode.

[0188] S602: The router confirms the Probe Response message.

[0189] In one implementation, an IE field may be added to the Probe Response message, and the IE field is used to indicate whether the AP that sends the Beacon message can be connected.

[0190] For example, a multi-band router includes a 2.4 GHz band and a 5 GHz band. The AP corresponding to the 2.4 GHz band sends a ProbeResponse message 1, in which an IE field can be added, and the IE field in the ProbeResponse message 1 is used to indicate whether the 2.4 GHz band can be connected; the AP corresponding to the 5 GHz band sends a ProbeResponse message 2, in which an IE field can be added, and the IE field in the ProbeResponse message 2 is used to indicate whether the 5 GHz band can be connected.

[0191] It is understandable that if the current AP can be connected, it means that the number of access terminals in the frequency band corresponding to the current AP has not reached the maximum access number; if the current AP cannot be connected, it means that the number of access terminals in the frequency band corresponding to the current AP has reached the maximum access number. For example, when the number of AP access terminals in the 5GHz frequency band has reached the second threshold, the IE field in Probe Response message 2 indicates that the AP corresponding to the 5GHz frequency band cannot be connected; when the number of AP access terminals in the 2.4GHz frequency band has not reached the first threshold, the IE field in Probe Response message 1 indicates that the AP corresponding to the 2.4GHz frequency band can be connected.

[0192] S603: The router sends a Probe Response message, and correspondingly, the mobile phone receives the Probe Response message.

[0193] It is understandable that the AP of the frequency band in which the number of router access terminals has reached the maximum access number does not send the Probe Response message, and the AP of the frequency band in which the number of router access terminals has not reached the maximum access number can send the Probe Response message.

[0194] Exemplarily, when the number of AP access terminals in the 5 GHz band has reached the second threshold, the AP in the 5 GHz band does not send a Probe Response message; when the number of AP access terminals in the 2.4 GHz band has not reached the first threshold, the AP in the 2.4 GHz band may send a Probe Response message.

[0195] Similar to the above method 500, the method 600 may also be applicable to the following scenarios:

[0196] Scenario 1: The mobile phone supports IE parsing.

[0197] S604: The mobile phone parses the Probe Response message.

[0198] It should be noted that the mobile phone receives a Probe Response message sent from an AP in a frequency band where the number of access terminals does not reach the maximum access number, and further, the mobile phone parses the IE field in the Probe Response message to determine that the AP that sent the message can be connected.

[0199] It is understandable that, for a mobile phone that supports IE parsing, step S604 is optional.

[0200] For example, a router that supports multiple frequencies includes a 2.4 GHz band and a 5 GHz band. The number of AP access terminals in the 5 GHz band has reached the second threshold, and the number of AP access terminals in the 2.4 GHz band has not reached the first threshold. The mobile phone only receives Probe Response messages from APs in the 2.4 GHz band, based on which the mobile phone determines that the APs in the 2.4 GHz band can be connected. Alternatively, when the mobile phone receives a Probe Response message from an AP in the 2.4 GHz band, for greater security, the Probe Response message can be further parsed to determine that the APs in the 2.4 GHz band can be connected.

[0201] S605: The mobile phone initiates a connection according to the parsed Probe Response message.

[0202] It should be noted that when the mobile phone determines that a certain AP can be connected by parsing the Probe Response message, it will further initiate a connection with the AP. The mobile phone can complete the access process through the authentication and association process with the AP.

[0203] It is understandable that, when the mobile phone does not execute the above step S604, it can directly initiate a connection to the AP that sends the Probe Response message.

[0204] Scenario 2: The mobile phone does not support IE parsing.

[0205] S606: The mobile phone initiates a connection according to the Probe Response message.

[0206] It should be noted that for mobile phones that do not support IE parsing, they can directly initiate a connection to the AP that sends the Probe Response message.

[0207] Based on the above scheme, the communication method provided in the embodiment of the present application can be applicable to the scenario where the terminal accesses a multi-band router that supports the 5 GHz frequency band preference. When the number of AP access terminals of a certain frequency band of the router has reached the maximum access number, by modifying the router broadcast message (for example, adding an IE field, adjusting the signal quality of the broadcast message, or modifying the broadcast period of the message), or providing feedback on the router side based on whether the number of frequency band access terminals has reached the maximum access number, the terminal can successfully access other frequency bands when the number of terminals that have accessed a certain frequency band of the router has reached the maximum access number, thereby improving the user's network experience.

[0208] like Figure 7 As shown, a communication method provided by an embodiment of the present application is shown, and the method can be applied to Figure 3 In the scenario shown, the method is described in detail below. It should be noted that the execution order of the steps of the communication method provided in the embodiment of the present application is not limited to Figure 7 The order shown is limited.

[0209] It should be noted that the message sent by the routing device to the terminal may be a Beacon message or a ProbeResponse message. Depending on the message type, the communication method 700 provided in the embodiment of the present application may be different.

[0210] It should be noted that the communication method provided in the embodiment of the present application can be applied to a routing device including at least two frequency bands, the at least two frequency bands include a first frequency band and a second frequency band, and the routing device supports the terminal to prefer a certain frequency band.

[0211] Exemplarily, the routing device is a multi-band router that supports the 5 GHz frequency band, wherein the first frequency band is the 2.4 GHz frequency band and the second frequency band is the 5 GHz frequency band.

[0212] In one implementation, when the message sent by the routing device to the terminal is a Beacon message, the method 700 may include step S702 and step S704.

[0213] S702: The routing device sends at least two messages, and correspondingly, the terminal receives at least two messages.

[0214] Specifically, at least two messages are used for the terminal to discover the routing device. The at least two messages include a first message and a second message, the first message corresponds to the first frequency band, and the second message corresponds to the second frequency band.

[0215] It should be noted that APs of multiple frequency bands of the routing device can send messages. The first message is sent through the AP of the first frequency band of the routing device, and the second message is sent through the AP of the second frequency band of the routing device. Exemplarily, the AP of the 2.4GHz frequency band sends the first message, and the AP of the 5GHz frequency band sends the second message. Both the first message and the second message can be sent by broadcasting.

[0216] In one implementation, at least two messages include a first field, the first field of the first message is used to indicate that the number of access point access terminals in the first frequency band has not reached a first threshold, and the first field of the second message is used to indicate that the number of access point access terminals in the second frequency band has reached a second threshold.

[0217] That is, the first frequency band is a non-fully connected frequency band, and the second frequency band is a fully connected frequency band. It should be understood that the first threshold and the second threshold can be the same or different. The first threshold is the maximum number of access terminals of the access point of the first frequency band, and the second threshold is the maximum number of access terminals of the access point of the second frequency band.

[0218] Exemplarily, the first field is an IE field. The routing device may add an IE field to the Beacon message to indicate whether the AP that sends the Beacon message can be connected.

[0219] In one implementation, the routing device may reduce the signal quality of the second message before sending the at least two messages.

[0220] It should be noted that the number of access terminals of the second frequency band corresponding to the second message has reached the second threshold, and reducing the signal quality of the second message can reduce the possibility of the terminal discovering the AP of the second frequency band.

[0221] In one implementation, before sending at least two messages, the routing device may increase the period of the second message. The routing device sends the first message at a first period and sends the second message at a second period, and the second period is greater than the first period.

[0222] It should be noted that increasing the sending period of the second message for an AP whose maximum number of access terminals has been reached can reduce the possibility of the terminal discovering the AP in the second frequency band, thereby increasing the possibility of the terminal discovering the AP in the first frequency band, and helping to guide the terminal to access the AP in the first frequency band.

[0223] It should be noted that the SSID of the first frequency band is the same as the SSID of the second frequency band. Figure 4 As shown in (b) in the figure, in the user interface, the SSIDs of multiple frequency band APs supporting 5 GHz frequency band preference are only displayed as one "ID123".

[0224] S704: The terminal initiates a connection to an access point of the first frequency band.

[0225] It should be noted that when the terminal supports parsing the first field, before the terminal initiates a connection, it can first parse at least two received messages, and determine based on the first field in the at least two messages that the number of access point access terminals in the first frequency band has not reached the first threshold, and the number of access point access terminals in the second frequency band has reached the second threshold.

[0226] When the terminal supports parsing the first field, the terminal can determine to initiate a connection to the access point of the first frequency band by parsing the first field. Of course, the terminal can also determine to initiate a connection to the access point of the first frequency band based on the message sending period and / or the signal quality of the message.

[0227] When the terminal does not support parsing the first field, the terminal cannot directly determine to initiate a connection to the access point of the first frequency band by parsing the first field. At this time, the terminal needs to determine to initiate a connection to the access point of the first frequency band by the message sending period and / or the signal quality of the message.

[0228] In an implementation manner, when the message sent by the routing device to the terminal is a Probe Response message, the method 700 may include steps S701, S703, and S704.

[0229] S701, the terminal sends a request message, and correspondingly, the routing device receives the request message.

[0230] It should be noted that the request message can be sent by broadcasting.

[0231] S703: The routing device sends a first message, and correspondingly, the terminal receives the first message.

[0232] It should be noted that the routing device sends the first message and does not send the second message. The routing device sends the first message in a unicast manner.

[0233] It should be noted that when the request message is a Probe Request message, the first message and the second message are response messages to the request message, and the first message and the second message are Probe Response messages. The first message is a message sent by the routing device through the AP of the first frequency band, and the second message is a message sent by the routing device through the AP of the second frequency band.

[0234] That is, after receiving the request message from the terminal, the routing device does not send the Probe Response message through the AP to which the number of access terminals has reached the maximum number, but can send the Probe Response message through the AP to which the number of access terminals has not reached the maximum number.

[0235] Exemplarily, when the 5 GHz band is fully connected, the AP in the 5 GHz band does not send a Probe Response message; when the 2.4 GHz band is not fully connected, the AP in the 2.4 GHz band may send a Probe Response message.

[0236] In one implementation, before sending the first message, the routing device may add a first field in the first message, where the first field in the first message is used to indicate that the number of access point access terminals in the first frequency band does not reach a first threshold.

[0237] S704: The terminal initiates a connection to an access point of the first frequency band.

[0238] Based on step S703, the routing device sends the first message through the first frequency band and does not send the second message through the second frequency band. The terminal will also receive the first message but not the second message. The terminal can initiate a connection to the access point of the first frequency band according to the received first message.

[0239] The communication method provided in the embodiment of the present application can be applied to a multi-band router that supports a preferred 5GHz frequency band. When the 5GHz frequency band of the router is fully connected, the possibility of the terminal discovering (or scanning) the 5GHz frequency band AP is reduced by increasing the sending period of the 5GHz frequency band AP sending the message, reducing the signal quality of the 5GHz frequency band AP sending the message, or adding a field for indicating whether the AP can be connected in the message sent by the router, thereby reducing the possibility of the terminal discovering (or scanning) the 5GHz frequency band AP, and guiding the terminal to select an AP whose number of other access terminals has not reached the maximum number, thereby ensuring a good network experience for users.
