Description
Technical Field

Background

In order to reduce the influence on the terminal device using the old standard, the new standard may generally be compatible with the old standard, but such compatibility may result in a wireless Access Point (AP) using the new standard, and after accessing the terminal device using the old standard, the total transmission capability of the AP is affected, and the transmission performance is greatly reduced. To reduce this effect, a common solution is that when a terminal device using an old standard attempts to access an AP using a new standard, the AP will deny the terminal device access by sending an error code to the terminal device during the association phase of the connection.
However, since the error code is introduced based on the new WIFI standard, the terminal device using the old standard cannot correctly understand and process the error code, which may cause the terminal device to repeatedly try to reconnect to the AP, which may result in a poor use experience for the user, and may also cause additional packet loss if the terminal device happens to be in the process of roaming while repeatedly trying to connect to the AP.

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.
In a current WIFI network, a user may perform wireless communication in a manner of accessing various terminal devices to a wireless Access Point (AP), where the terminal device includes: electronic equipment such as a mobile phone, a tablet computer and a notebook computer which can be connected with a WIFI network; an AP is a device, such as a wireless router or the like, that provides access to a WIFI network.
Before accessing to an AP, a terminal device of a user generally scans in a local area to discover APs existing around, and then provides the discovered APs to the user in a form of a wireless network list, where the wireless network list includes information such as wireless network identifiers and signal strengths corresponding to the scanned APs, and the wireless network identifiers may be represented by Service Set Identifiers (SSIDs) corresponding to the APs. And the user selects an AP which the current terminal equipment wants to access according to the information contained in the wireless network list.
Fig. 1 is a schematic diagram of an access process between a terminal device and an AP according to an embodiment of the present invention. As shown in fig. 1, in response to a selection operation triggered by a user in a wireless network list, for example, clicking an SSID corresponding to the AP, a terminal device starts to attempt to access the AP, where an access process specifically includes three stages of scanning, authentication, and association, and a specific processing procedure is as follows:
a scanning stage: the method comprises the steps that terminal equipment sends a Probe Request (Probe Request) to an AP through active scanning, wherein the Probe Request comprises an SSID of the AP and a Supported rate (Supported Rates) of the terminal equipment; after receiving the Probe request, the AP analyzes the supported rate of the terminal device, and sends a Probe Response (Probe Response) to the terminal device in combination with the actual situation of the AP, where the Probe Response includes whether the AP allows the terminal device to access and the supported rate of the AP.
And an authentication stage: the terminal equipment receives the detection response, analyzes the detection response, and sends an Authentication Request (Authentication Request) to the AP if the AP is allowed to be accessed by the terminal equipment and the terminal equipment determines to join the AP, wherein the Authentication Request comprises the type of an Authentication algorithm; after receiving the Authentication request, the AP performs identity Authentication on the terminal device according to the type of the Authentication algorithm, and sends an Authentication Response (Authentication Response) to the terminal device to feed back an Authentication result.
And a correlation stage: the terminal equipment receives the authentication response, if the authentication is successful and the terminal equipment decides to join the AP, an Association Request (Association Request) is sent to the AP, and the Association Request indicates the network type to be joined, the listening Interval (Listen Interval) of the terminal equipment and the like; after receiving the Association request, the AP determines whether each requirement in the Association request can be accepted, and if so, sends an Association Response (Association Response) carrying Association ID (AID for short) and success information to the terminal device, indicating that the Association is successful, and the terminal device accesses the AP and can perform wireless communication; otherwise, sending a correlation response carrying the failed information to the terminal equipment to indicate that the correlation fails.
In practical applications, WIFI communication standards (hereinafter referred to as standards) undergo a continuous upgrade process from 802.11 to 802.11b, 802.11g (WIFI-3), 802.11n (WIFI-4), 802.11ac (WIFI-5), 802.11ax (WIFI-6), etc. with the development of communication technology, in order to reduce the influence on terminal devices using the old standards, the new standards are usually compatible with the old standards, however, such compatibility may cause an AP using the new standards, after accessing the terminal devices using the old standards, the total transmission capability of the AP is affected, and the transmission performance is greatly reduced. The first wireless communication standard and the second wireless communication standard mentioned in the embodiments of the present invention described below may be different WIFI communication standards.
In order to reduce the impact of terminal device access using the old standard on the transmission performance of the AP using the new standard, the AP may prohibit access by terminal devices using the old standard. As shown in fig. 1, when a terminal device using an old standard attempts to access an AP using a new standard, the AP generally confirms the standard used by the terminal device at an association stage, and if the standard used by the terminal device is not consistent with the standard used by the AP itself, sends an association response including an error code to the terminal device to deny the access of the terminal device, and informs the terminal device of a reason for denying the access through the error code; if yes, executing the processing procedure after receiving the association request as described in the association stage, and sending an association response to the terminal device.
For example, assume that the terminal device of the user uses WIFI-4 and the AP uses WIFI-6, and the administrator sets in advance in the AP management software: only allowing the terminal equipment using WIFI-6 to access; after the terminal device completes the scanning stage and the authentication stage as shown in fig. 1, in the association stage, after the AP receives the association request, it is determined that the WIFI-4 used by the terminal device is inconsistent with the WIFI-6 used by the AP, and an association response including the error code 104 is sent to the terminal device to reject the access of the terminal device.
However, since the error code 104 is introduced based on the new WIFI-6, the terminal device using WIFI-4 cannot correctly understand and process the error code 104, after receiving the association response containing the error code 104, the terminal device confirms that the access to the AP is unsuccessful, and will re-send the probe request to the AP, re-attempt to access the AP, repeatedly attempt to reconnect the AP by the terminal device, and the connection is unsuccessful, which may result in a poor use experience for the user, and may also cause additional packet loss if the terminal device happens to be in the roaming process when repeatedly attempting to connect to the AP.
In view of this, an embodiment of the present invention provides a wireless access method, so as to solve the problem that a terminal device cannot quickly access a suitable AP.
In the embodiment of the present invention, one AP has multiple wireless frequency bands to which terminal devices can access, where each frequency band has a wireless network identifier (SSID) corresponding to each frequency band, an AP administrator can configure standards supported by each wireless frequency band in AP management software, and if the standards supported by the terminal devices are matched with the standards configured by the wireless frequency bands, the terminal devices are allowed to access the wireless frequency bands corresponding to the AP.
In order to ensure that the terminal device of the user can normally access the AP, in practical applications, at least one radio frequency band exists among a plurality of radio frequency bands of one AP, and is configured to support multiple standards, for example, one radio frequency band exists and is configured to support all existing standards.
In this embodiment, it is assumed that the first wireless communication standard supported by the terminal device currently used by the user is WIFI-5, in an environment where the user is located, there is only one wireless access point AP1, and the AP1 has two wireless frequency bands, where the first wireless frequency band is 5GHz, the corresponding first wireless network identifier is a first SSID, and the supported second wireless communication standard is configured as WIFI-6; the second wireless frequency band is 2.4GHz, the corresponding second wireless network is identified as a second SSID, and the second wireless communication standard supported by the second SSID is configured to support at least WIFI-5, for example, may be configured to support common WIFI-4, WIFI-5 and WIFI-6.
Based on the above assumption, it is easily understood that, since the current environment in which the user is located is only the AP1, only the first SSID and the second SSID are in the wireless network list displayed on the terminal device of the user. When the user wants the terminal device to access the AP1, the terminal device and the AP1 need to perform the steps in the embodiment shown in fig. 2 in response to the selection operation triggered by the user in the wireless network list, and fig. 2 is an interaction flowchart of a wireless access method provided by the embodiment of the present invention.
In response to the user's selection operation of the first SSID in the wireless network list, the terminal device determines to access the 5GHz band of the AP1, and the terminal device and the AP1 perform the following steps:
201. the terminal device sends a first probe request to the AP1 corresponding to the selected first SSID, where the first probe request includes a first wireless communication standard WIFI-5 and the first SSID supported by the terminal device.
202. The AP1 receiving the first probe request; and judging whether the second wireless communication standard supported by the 5GHz frequency band of the AP1 is consistent with the first wireless communication standard supported by the terminal equipment contained in the first detection request, and if the fact that the WIFI-6 corresponding to the 5GHz frequency band is inconsistent with the WIFI-5 supported by the terminal equipment contained in the first detection request is determined, not responding to the first detection request, namely, not sending the first detection response to the terminal equipment.
203. And if the terminal equipment does not receive the first detection response, deleting the first SSID in the wireless network list.
Based on the assumed conditions in this embodiment, the AP1 does not send the first probe response to the terminal device, and after the terminal device deletes the first SSID in the wireless list, the user knows that the 5GHz band of the AP1 corresponding to the first SSID is not accessed, and then the user tries to access the terminal device to the wireless band corresponding to the remaining wireless network identifier in the wireless network list, that is, the 2.4GHz band of the AP1 corresponding to the second SSID.
In response to the user's selection operation of the second SSID in the updated wireless network list, the terminal device determines to access the 2.4GHz band corresponding to the AP1, and the terminal device and the AP1 perform the following steps:
204. and the terminal sends a second probe request to the AP1 corresponding to the selected second SSID, where the second probe request includes the first wireless communication standard WIFI-5 and the second SSID supported by the terminal device.
205. The AP1 receives the second probe request; and determining that the second wireless communication standard supported by the 2.4GHz frequency band corresponding to the AP1 is matched with the WIFI-5 supported by the terminal equipment contained in the second detection request.
206. The AP1 sends a second probe response to the terminal device.
207. And the terminal equipment receives the second probe response and accesses the 2.4GHz frequency band of the AP 1.
In step 205, the second wireless communication standard supported by the 2.4GHz band corresponding to the AP1 is matched with the WIFI-5 supported by the terminal device included in the second probe request, which may be understood that the second wireless communication standard includes WIFI-5; in step 207, after receiving the probe response, the terminal device accesses the wireless frequency band of the AP corresponding to the SSID, which may refer to the authentication stage and the association stage in the access process shown in fig. 1, which is not described in this embodiment and subsequent embodiments.
In the embodiment shown in fig. 2, it is illustrated that the terminal device of the user accesses different frequency bands of the same AP (AP1), and it is easily understood that, in an actual application scenario, an environment in which the user is located includes more than one AP, but in practice, no matter there are several APs, based on an SSID selected by the user in a wireless network list each time, the terminal device and the AP corresponding to the SSID will perform the same determination process as that shown in fig. 2, and finally access a certain frequency band of one AP after authentication and association are successful.
In order to better understand the wireless access method when multiple APs exist, in another embodiment of the present invention, it is assumed that the first wireless communication standard supported by the terminal device currently used by the user is WIFI-5, and there are 2 wireless access points around the user, which are AP1 and AP2, respectively, where the AP1 has two wireless frequency bands, the first wireless frequency band is 5GHz, the corresponding wireless network is identified as SSID-a, and the supported second wireless communication standard is configured as WIFI-6; the second wireless frequency band is 2.4GHz, the corresponding wireless network identifier is SSID-b, and the second wireless communication standard supported by the second wireless frequency band is configured to support at least WIFI-5, such as common WIFI-4, WIFI-5 and WIFI-6; the AP2 also has two wireless frequency bands, wherein the first wireless frequency band is 5GHz, the corresponding wireless network identifier is SSID-c, and the supported second wireless communication standard is WIFI-6; the second wireless frequency band is 2.4GHz, the corresponding wireless network identifier is SSID-d, and the supported second wireless communication standard is configured to support at least WIFI-5, for example, common WIFI-4, WIFI-5, and WIFI-6 may be supported.

Optionally, in response to a user-triggered wireless network list display operation, such as: and clicking a wireless network list display button, and sequentially displaying wireless network identifications corresponding to the APs which exist around according to the high-low sequence of the wireless communication standard supported by the APs which exist around when the plurality of APs scanned by the terminal equipment are displayed in the wireless network list. Corresponding to the above assumption, in the wireless network list, the wireless network identifiers are sequentially displayed in the order of SSID-a, SSID-c, SSID-b, SSID-d. The user can sequentially select the wireless network identifications corresponding to the wireless frequency bands of the APs to be accessed from top to bottom according to the display sequence in the wireless network list.
Optionally, in response to a user-triggered wireless network list display operation, such as: when a wireless network list display button is clicked and a plurality of APs scanned by the terminal device are displayed in the wireless network list, a first wireless access point of default access set by the user may also be highlighted in the wireless network list, for example: adding a special mark to the first wireless access point to realize highlighting; the first wireless access point accessed by default can be a wireless access point frequently used by a user or a wireless access point with priority for access; the first wireless access point of the default access set by the user is highlighted in the wireless network list, so that the user can quickly discover and select to access the first wireless access point.
Optionally, when the first wireless access point is replaced with the second wireless access point due to device replacement or the like, in response to the first wireless access point being replaced with the second wireless access point, the terminal device outputs prompt information for prompting the user to set the second wireless access point as the default-access wireless access point, so as to highlight the second wireless access point in the wireless network list after the user sets the second wireless access point as the default-access wireless access point.

406. and the terminal equipment simultaneously sends second probe requests to the AP1 corresponding to the selected SSID-b and the AP2 corresponding to the SSID-d, wherein each second probe request comprises the first wireless communication standard WIFI-5 and the SSID supported by the terminal equipment.
407. The AP1 receives a second probe request, wherein the probe request comprises SSID-b; and determining that the second wireless communication standard supported by the 2.4GHz frequency band of the AP1 is matched with the WIFI-5 supported by the terminal equipment contained in the second detection request.
408. The AP1 sends a second probe response to the terminal device.
409. The AP1 receives a second probe request, wherein the probe request comprises SSID-d; and determining that the second wireless communication standard supported by the 2.4GHz frequency band of the AP2 is matched with the WIFI-5 supported by the terminal equipment contained in the second detection request.
410. The AP2 sends a second probe response to the terminal device.
411. The terminal device receives second probe responses sent by the AP1 and the AP2, and determines the AP1 with stronger signal strength as a target AP to be accessed according to the respective signal strengths corresponding to the AP1 and the AP 2; and accessing the 2.4GHz frequency band of the AP1 according to the second probe response of the AP 1.
In the assumed conditions of the foregoing embodiments, the first wireless communication standard supported by the terminal device is WIFI-5, and no matter the 5GHz band of the AP1 or the 5GHz band of the AP2, due to the fact that the WIFI-5 supported by the terminal device is not consistent with the second wireless communication standard WIFI-6 supported by the 5GHz bands of the AP1 and the AP2, the AP1 and the AP2 do not respond to the probe request sent by the terminal device, so as to achieve the fact that the 5GHz bands of the AP1 and the AP2 are hidden by the terminal device, and the terminal device does not try to access the 5GHz bands hidden by the AP1 and the AP2 any more.
If the first wireless communication standard supported by the terminal device is not WIFI-5 but WIFI-6, based on the assumption of the specific situation of the AP in the environment where the user is located in the embodiments, when the AP receives a probe request which is sent by the terminal device and includes an SSID corresponding to the 5GHz band of the AP, it is determined whether the second wireless communication standard supported by the 5GHz band of the AP is consistent with the first wireless communication standard WIFI-6 supported by the terminal device included in the probe request, and since the second wireless communication standards supported by the 5GHz bands of the terminal device and the AP are both WIFI-6 and are consistent, the AP sends a probe response to the terminal device, so that the terminal device performs subsequent authentication and association processes with the AP according to the probe response.
When the user selects multiple SSIDs in the wireless network list at the same time, the probe response received by the terminal device may be more than one, for example, after determining that the first wireless communication standard and the second wireless communication standard supported by the terminal device and the 5GHz band of the AP are both WIFI-6, the AP1 and the AP2 both send probe responses to the terminal device, at this time, the terminal device may compare the signal strengths of the AP1 and the AP2, and if it is determined that the signal strength of the AP1 is higher than the signal strength of the AP2, select the 5GHz band to be accessed to the AP1, and perform subsequent authentication and association with the AP 1.
In the solution provided in the embodiment of the present invention, when a terminal device attempts to access a wireless access point, first, in response to a selection operation triggered by a user in a wireless network list, the terminal device sends a first probe request to a wireless access point corresponding to a selected first wireless network identifier, where the first probe request includes a first wireless communication standard and a first wireless network identifier supported by the terminal device, and the first wireless network identifier corresponds to a first wireless frequency band of the wireless access point; then, the wireless access point corresponding to the first network identifier receives the first detection request, judges whether the first wireless communication standard is consistent with a second wireless communication standard corresponding to the first wireless frequency band, if so, sends a detection response to the terminal equipment, and the terminal equipment accesses the first wireless frequency band of the wireless access point after receiving the detection response; and if the first detection request is not consistent with the second detection request, the terminal equipment does not respond to the first detection request, and if the terminal equipment does not receive the first detection response corresponding to the first detection request, the first wireless network identifier is deleted from the wireless network list.
After the terminal device deletes the first wireless network identifier in the wireless network list, the user may reselect the corresponding wireless frequency band of the wireless access point corresponding to the other wireless network identifier according to the updated wireless network list, and finally access the wireless frequency band of one wireless access point.
In the scheme provided by the embodiment of the invention, after receiving a detection request, a wireless access point judges whether a first wireless communication standard supported by a terminal device is consistent with a second wireless communication standard corresponding to a wireless frequency band of the wireless access point which the terminal device wants to access currently, if not, the detection request is not responded, and the terminal device tries to access the frequency band of the wireless access point corresponding to other wireless network identifiers; compared with the traditional scheme that the judgment is carried out only in the association stage and the error code is returned when the judgment is inconsistent, the scheme can save the time for the terminal equipment to access the wireless access point, and can not generate the problem of repeatedly trying to access the wireless frequency band of the wireless access point corresponding to the same wireless network identifier, and the terminal equipment of the user can access the proper wireless access point at a higher speed.
