Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a network access method, apparatus, device, and storage medium. Background Technology

[0002] Currently, most Stations (STAs) connect to Access Points (APs) through a process involving scanning, authentication, and association. During the association process, STAs utilize the highest supported capabilities, including: Wireless Fidelity (WiFi) version, Maximum Modulation and Coding Scheme (MCS) modulation level, bandwidth, Aggregate-Management Protocol DataUnit (A-MPDU) aggregation depth, and number of spatial streams. Furthermore, STAs and APs can negotiate these parameters, aiming to utilize the most efficient MCS modulation level, higher bandwidth, larger A-MPDU aggregation depth, and a greater number of spatial streams to achieve the highest uplink and downlink bidirectional transmission rates.

[0003] However, the highest uplink and downlink bidirectional transmission rate comes at the cost of reduced anti-interference capability, which can easily lead to transmission failure. As a result, the STA will attempt to retransmit, which reduces available bandwidth and increases transmission latency. For cloud video applications that are sensitive to bandwidth and latency jitter, this has already resulted in a poor user experience, such as stuttering and unsmooth operation. Summary of the Invention

[0004] This application provides a network access method, apparatus, device, and storage medium to select a suitable network access parameter set under a certain level of interference, thereby ensuring the picture quality of cloud video applications and the smoothness of user operation.

[0005] In a first aspect, embodiments of this application provide a network access method, comprising: determining interference information of a target channel, wherein the target channel is a channel between a STA and a currently connected AP; determining a target network access parameter group corresponding to the interference information; disconnecting the connection between the STA and the AP; and accessing the AP according to the target network access parameter group.

[0006] Secondly, embodiments of this application provide a network access device, including: a determining module, a disconnecting module, and an accessing module, wherein the determining module is used to determine interference information of a target channel, the target channel being the channel between a STA and a currently connected access point AP; and to determine a target network access parameter group corresponding to the interference information; the disconnecting module is used to disconnect the connection between the STA and the AP; and the accessing module is used to access the AP according to the target network access parameter group.

[0007] Thirdly, embodiments of this application provide an electronic device, including: a processor and a memory, the memory being used to store a computer program, and the processor being used to call and run the computer program stored in the memory to perform the methods as described in the first aspect or its various implementations.

[0008] Fourthly, embodiments of this application provide a computer-readable storage medium for storing a computer program that causes a computer to perform the methods described in the first aspect or its various implementations.

[0009] Fifthly, embodiments of this application provide a computer program product including computer program instructions that cause a computer to perform the methods as described in the first aspect or its various implementations.

[0010] Sixthly, embodiments of this application provide a computer program that causes a computer to perform the methods as described in the first aspect or its various implementations.

[0011] Through the technical solution of this application, the STA can first determine the interference information of the target channel between itself and the currently connected AP, and then determine the target network access parameter group corresponding to the interference information. After disconnecting the connection between the STA and the AP, the STA can reconnect to the AP according to the aforementioned target network access parameter group. In other words, under a certain level of interference, the STA can select an appropriate network access parameter group, thereby ensuring the picture quality of cloud video applications and the smoothness of user operation.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0020] In this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or solution described as "exemplary" or "for example" in this application should not be construed as being better or more advantageous than other embodiments or solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0021] As mentioned above, currently, when the STA uses the highest capabilities it can support, it can achieve the highest uplink and downlink bidirectional transmission rates. However, this maximum bidirectional transmission rate comes at the cost of reduced interference resistance, which can easily lead to transmission failures. As a result, the STA will attempt to retransmit, resulting in a reduction in available bandwidth and an increase in transmission latency. For cloud video applications that are sensitive to bandwidth and latency jitter, this has already caused a poor user experience, such as stuttering and unresponsive operation.

[0022] To address the aforementioned technical issues, the proposed solution is as follows: Under certain interference conditions, the STA should select an appropriate network access parameter set to ensure the picture quality of cloud video applications and the smoothness of user operation.

[0023] It should be understood that the technical solution of this application can be applied to the following scenarios, but is not limited to:

[0024] For example, Figure 1An application scenario diagram provided for an embodiment of this application, such as... Figure 1 As shown, this application scenario may include STA110, AP120, and server 130. STA110 and AP120 can communicate through an Application Programming Interface (API), and AP120 and server 130 can communicate with each other.

[0025] The connection establishment between a STA and an AP can be divided into three steps: scanning, authentication, and association. When a STA enters the coverage area of ​​an AP, it can scan for APs within that area. Specifically, the STA can actively scan different channels; alternatively, the STA can listen to beacon frames periodically sent by APs on each of its supported channels to identify nearby APs. Each AP is located on a channel, and different APs can be on different channels or the same channel. After scanning, the STA needs to authenticate the scanned APs. For example, the STA can authenticate using Open Systems Authentication (OSA), shared key authentication, or pre-authentication. After authentication, the STA can associate with the AP and negotiate network access parameters. Specifically, the STA can send an association request frame to the AP, including network access parameters, various STA parameters, and parameters selected according to the service configuration. Upon receiving the association request frame, the AP can determine whether the STA needs to perform access authentication and respond to the STA accordingly. Once association is complete, it indicates that a wireless link has been established between the STA and the AP.

[0026] In some possible implementations, the STA can be a mobile phone, tablet, desktop, laptop, handheld computer, notebook computer, in-vehicle device, Ultra-Mobile Personal Computer (UMPC), netbook, as well as cellular phone, Personal Digital Assistant (PDA), Augmented Reality (AR) / Virtual Reality (VR) device, etc., but is not limited to these.

[0027] An Access Point (AP) is a hub in a traditional wired network and is the most commonly used device for building small wireless local area networks (WLANs). An AP acts as a bridge between the wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to the Ethernet. Most wireless APs support multi-user access, data encryption, and multi-rate transmission; some also have wireless network management functions. For small-scale wireless WLANs such as those in homes or offices, generally only one AP is needed to enable wireless access for all computers. The indoor coverage range of an AP is typically 30m to 100m.

[0028] It should be understood that the server can be a server that supports cloud video applications on the STA. This server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, or a cloud server that provides cloud computing services.

[0029] also, Figure 1 An exemplary setup is shown, comprising one STA, one AP, and one server. In practice, other numbers of STAs, APs, and servers may be included, and this application is not limited thereto.

[0030] After introducing the application scenarios of the embodiments of this application, the technical solution of this application will be described in detail below:

[0031] Figure 2 A flowchart illustrating a network access method provided in this application embodiment, the method can be performed by, for example... Figure 1 The STA110 shown is executed, but is not limited to this, such as Figure 2 As shown, the method may include:

[0032] S201: STA determines the interference information of the target channel;

[0033] S202: STA determines the target network access parameter group corresponding to the interference information;

[0034] S203: The STA disconnects from the AP;

[0035] S204: The STA accesses the AP according to the target network access parameter group.

[0036] The target channel is the channel between the STA and the AP currently connected to the STA. It should be understood that the target channel is the channel on which the AP is located.

[0037] In some implementations, the STA can determine interference information of the target channel before data transmission with the server begins. For example, the STA can determine the interference information of the target channel when the user has just started the cloud video application, but before cloud video data transmission has begun.

[0038] In other possible implementations, the STA can determine the interference information of the target channel upon receiving a pause operation. The pause operation can be a double-click on the page where the cloud video is playing, or a click on the pause button on the page where the cloud video is playing, but is not limited to these.

[0039] In some other implementations, the STA can determine the interference information of the target channel upon receiving a refresh operation. The refresh operation can be a user's pull-down action on the currently viewed cloud video playlist page or webpage, or a user's click on the refresh button on the currently viewed cloud video playlist page or webpage, but is not limited to these.

[0040] In other possible implementations, the STA can determine interference information for the target channel when it detects that the current network environment is experiencing lag. For example, when a user opens a cloud video application or webpage, the STA can proactively detect the current network environment and, after determining that the strength of the currently connected Wi-Fi signal is below a first threshold, determine the interference information for the target channel. Alternatively, the STA can determine the interference information for the target channel when it detects information such as "buffering" or "loading" displayed on the current cloud video playback page or webpage.

[0041] It should be understood that this application does not impose a time limit on the STA's determination of interference information for the target channel.

[0042] In some feasible implementations, the STA can obtain scanning results by scanning the entire frequency band or a portion of the frequency band, and then determine the interference information based on the scanning results.

[0043] For example, the full frequency band can be a 2.4 GHz band or a 5 GHz band; this application does not limit this.

[0044] For example, a portion of the frequency band may include the first frequency band where the target channel is located and the adjacent frequency bands of the first frequency band. For instance, if the target channel is channel 1 in the 2.4 GHz frequency band, then the STA can scan channels 1-13 in the 2.4 GHz frequency band, and this application does not impose any restrictions on this.

[0045] In some implementations, the STA can scan according to a preset scanning order. For example, the STA can scan according to a preset channel scanning order. For instance, assuming each channel has a unique index, the STA can scan the channels in ascending order of channel index, or in descending order of channel index, or the STA can scan the target channel first, and then scan the other channels in ascending or descending order of channel index. In short, this application does not limit the preset channel scanning order.

[0046] In some possible implementations, the above scanning results may include at least one of the following, but are not limited to: the signal strength of the AP, the WiFi interference strength of the target channel, the WiFi interference strength of the adjacent frequency band of the target channel, the non-WiFi interference strength of the target channel frequency band, i.e., the first frequency band, and the number of other STAs connected to the AP besides the STA.

[0047] In some possible implementations, the WiFi interference intensity of a target channel can be measured by at least one of the number of other APs on the target channel and the signal strength of each of the other APs, but is not limited to this. For example, the more APs on the target channel, the greater the WiFi interference intensity of the target channel; the greater the signal strength of the other APs on the target channel, the greater the WiFi interference intensity of the target channel.

[0048] In some possible implementations, the WiFi interference intensity of the adjacent frequency band can be measured by at least one of the number of other APs on the adjacent frequency band and the signal strength of each of the other APs, but is not limited thereto. For example, the more APs on the adjacent frequency band, the greater the WiFi interference intensity of the adjacent frequency band; the greater the signal strength of the other APs on the adjacent frequency band, the greater the WiFi interference intensity of the adjacent frequency band.

[0049] In some implementations, the non-WiFi interference intensity of the first frequency band may include at least one of the interference intensity of Bluetooth signals and cellular signals in the first frequency band.

[0050] It should be understood that the STA can determine the interference information of the target channel in any of the following possible ways, but is not limited to:

[0051] In one possible approach, the STA determines the score corresponding to each item in the above scanning results. The STA can then perform a weighted average of these scores to obtain the interference score and determine the interference score interval in which the interference score falls.

[0052] In the second possible method, the STA determines the priority of each item in the above scanning results, selects items whose priority is greater than the priority threshold, and further, the STA scores the selected items respectively. The STA can perform a weighted average of these scores to obtain the interference score and determine the interference score interval in which the interference score is located.

[0053] The following explains the two possible implementation methods:

[0054] In some implementations, the STA can pre-establish mapping relationships between signal strength ranges of multiple APs and multiple scores, mapping relationships between WiFi interference strength ranges of the target channel and multiple scores, mapping relationships between WiFi interference strength ranges of adjacent frequency bands of the target channel and multiple scores, mapping relationships between non-WiFi interference strength ranges of the first frequency band and multiple scores, and mapping relationships between the number ranges of other STAs connected to the AP (excluding the STA itself) and multiple scores. Based on this, the STA can obtain the scores corresponding to each or some items in the scan results according to the above scanning results and these mapping relationships.

[0055] In some possible implementations, the weights corresponding to each or some items in the scan results can be preset or dynamically set, and this application does not impose any restrictions on this.

[0056] For example, suppose the scan results include the AP signal strength score as s1, the WiFi interference strength of the target channel score as s2, the WiFi interference strength of the adjacent frequency bands of the target channel score as s3, the non-WiFi interference strength of the first frequency band score as s4, and the number of STAs other than STAs connected to the AP score as s5. Set the weights of each item in the above scan results to 0.3, 0.15, 0.15, 0.1, and 0.3 respectively, and then perform a weighted average of these items to obtain the interference score as (0.3*s1+0.15*s2+0.15*s3+0.1*s4+0.3*s5) / 5.

[0057] The second feasible method will be explained as follows:

[0058] In some possible implementations, the priority of each item in the above scan results can be preset or dynamically set, and this application does not impose any restrictions on this.

[0059] In some possible implementations, the aforementioned priority threshold can be preset or dynamically set, and this application does not impose any restrictions on this.

[0060] For example, a STA can set the priority of the AP's signal strength to 5, the priority of the WiFi interference intensity of the target channel to 4, the priority of the WiFi interference intensity of the adjacent frequency band of the target channel to 3, the priority of the non-WiFi interference intensity of the first frequency band to 2, and the priority of the number of other STAs connected to the AP (excluding the STA itself) to 1. The STA can set a priority threshold of 3. In this case, the STA determines the items with a priority higher than this priority threshold as: the AP's signal strength and the WiFi interference intensity of the target channel. Furthermore, the STA can score these two items according to the above scoring rules and perform a weighted average of the scores to obtain the final interference score and determine the interference score range in which this interference score falls.

[0061] In some feasible implementations, the STA can determine the level of interference based on the interference score range.

[0062] In some implementations, the STA can divide the total interference score interval to obtain multiple interference score intervals, each of which can correspond to a level of interference. Based on this, the STA can determine the level of interference according to the interference score.

[0063] For example, assuming the total interference score range is [0, 100], STA can divide this range into five interference score ranges: [80, 100], [60, 80], [40, 60], [20, 40], and [0, 20]. These correspond to interference levels of 1, 2, 3, 4, and 5, respectively. The correspondence between interference levels and interference score ranges can be shown in Table 1, but is not limited to this.

[0064] Table 1

[0065] Interference score range Interference level [80,100] Level 1 [60,80) Level 2 [40,60) Level 3 [20,40) Level 4 [0,20) Level 5

[0066] It should be understood that this application does not restrict how the interference score intervals are divided, nor does it restrict the correspondence between the degree of interference and the interference score intervals.

[0067] In some possible implementations, the aforementioned interference information may include at least one of the following, but is not limited to: interference level and interference score range.

[0068] In some feasible methods, the target network access parameter set corresponding to the interference information can be obtained through experiments. For example, given the interference information, for multiple sets of network access parameter sets, the application indicators on the application side are measured to obtain the optimal or suitable network access parameter set, which is then used as the target network access parameter set. In other words, through experiments, the STA can establish a mapping relationship between the interference information and the target network access parameter set.

[0069] In some possible implementations, any set of network access parameters provided in the embodiments of this application may include at least one of the following, but is not limited to: supporting maximum bandwidth, supporting maximum MCS modulation levels, supporting maximum A-MPDU aggregation degree, and other access parameters. These other access parameters may be relevant parameters that the STA and AP need to negotiate.

[0070] In some possible implementations, some parameters in any network access parameter group provided in the embodiments of this application may be used in Associate Request frames, and some parameters may be used in other Action frames, but are not limited thereto.

[0071] It should be understood that any of the above network access parameter sets can be used for uplink or downlink data transmission, and this application does not impose any restrictions on this.

[0072] In some implementations, after S204, the STA can negotiate the target network access parameter set with the AP, and can then transmit data with the server based on the negotiated target network access parameter set.

[0073] For example, suppose the target network access parameter set determined by the STA includes the following: maximum supported bandwidth of 40MHz, maximum supported MCS of 5, maximum supported A-MPDU aggregation degree of 16, other access parameter A is Y, and other access parameter B is ZX. The STA can include this target network access parameter set in an association request frame and send it to the AP. After receiving the association request frame, the AP can respond according to its own capabilities. Suppose the AP can support a maximum bandwidth of 20MHz, a maximum supported MCS of 5, and a maximum supported A-MPDU aggregation degree of 8. Then the AP can send its supported network access parameter set to the STA. After receiving these parameters, the STA selects the smaller network access parameter from the two network access parameter sets as the negotiated target network access parameter set, that is, the negotiated target network access parameter set includes: maximum supported bandwidth of 20MHz, maximum supported MCS of 5, and maximum supported A-MPDU aggregation degree of 8. Then the STA can transmit data with the server according to the negotiated target network access parameter set.

[0074] In some implementations, after the data transmission with the server is completed, the STA can disconnect from the AP, obtain the original network access parameter set, and reconnect to the AP based on the original network access parameter set. This application does not impose any restrictions on this.

[0075] It should be noted that the above-mentioned original network access parameter set is the network access parameter set used by the STA when connecting to the AP before reconnecting to the AP according to the target network access parameter set.

[0076] In other possible implementations, the STA can continue to use the target network access parameter set to maintain the connection with the AP after the data transmission with the server is completed, and this application does not limit this.

[0077] In summary, the technical solution provided by the embodiments of this application brings at least the following beneficial effects: when the interference level is certain, the STA can select a suitable network access parameter group, thereby ensuring the picture quality of cloud video applications and the smoothness of user operation.

[0078] Furthermore, since the STA can directly determine the target network access parameter group corresponding to the interference information based on the mapping relationship between the interference information and the target network access parameters, the STA can quickly determine the target network access parameter group, thereby efficiently ensuring the picture quality of cloud video applications and the smoothness of user operation.

[0079] As mentioned above, the target network access parameter set corresponding to the interference information can be obtained experimentally to establish the mapping relationship between the interference information and the target network access parameter set. This will be explained in detail below:

[0080] In some possible ways, Figure 3 A flowchart illustrating a method for establishing a mapping relationship between interference information and target network access parameter groups, as provided in this application embodiment, is shown below. Figure 3 As shown, the method may include:

[0081] S301: STA obtains multiple network access parameter groups;

[0082] S302: Under the interference conditions corresponding to the interference information, the STA accesses the AP according to each network access parameter group, negotiates with the AP for each network access parameter group, transmits data with the server, and measures the application indicators corresponding to the server.

[0083] S303: The STA sorts the application metrics corresponding to multiple network access parameter groups to determine the best application metrics;

[0084] S304: STA establishes a mapping relationship between interference information and the target network access parameter group corresponding to the best application indicators.

[0085] It should be understood that multiple network access parameter groups include a target network access parameter group. For example, multiple network access parameter groups can be as shown in Table 2:

[0086] Table 2

[0087]

[0088] It should be understood that S302 can be interpreted as an experimental phase for each network access parameter group. Before the STA's experimental phase for each network access parameter group, the STA can first disconnect its current connection with the AP. Then, under the interference environment corresponding to the aforementioned interference information, the STA connects to the AP according to the network access parameter group, negotiates the network access parameter group with the AP, and transmits data to the server using the negotiated network access parameter group to measure the corresponding application metrics of the server.

[0089] For example, a STA can send an association request frame containing a set of network access parameters to an AP. Upon receiving this frame, the AP can send its own set of network access parameters, including its maximum supported bandwidth, maximum supported MCS, and maximum supported A-MPDU aggregation degree, back to the STA. The STA can then use these two sets of network access parameters to establish a connection with the AP. For instance, the STA can choose the smaller of the two sets of network access parameters (maximum supported bandwidth, maximum supported MCS, and maximum supported A-MPDU aggregation degree) to establish a connection with the AP.

[0090] In the embodiments of this application, the STA can measure application metrics in the following scenarios, but is not limited to them: the STA can open a live streaming page in a cloud video application software and then measure the application metrics corresponding to the server at this time. This application does not limit this.

[0091] In some possible implementations, the application metrics include at least one of the following, but are not limited to: bandwidth jitter, latency jitter, and frame-by-frame stuttering rate.

[0092] In some feasible implementations, under the interference conditions corresponding to the above interference information, after the STA measures the application indicators based on different network access parameter groups, it can normalize the application indicators measured based on each network access parameter group, and perform a weighted average on the normalization results to obtain the weighted average value corresponding to these application indicators. The STA can determine the application indicator corresponding to the smallest weighted average value as the optimal application indicator.

[0093] For example, under interference level 1, the STA reconnects to the same AP using five different network access parameter groups: combination A, combination B, combination C, combination D, and combination E, respectively, and transmits data with the server. Five application metrics are measured, all including bandwidth jitter b1, latency jitter t1, and frame-by-frame stuttering rate s1. The weights of these metrics can be set to 0.3, 0.4, and 0.3, respectively. These five metrics are then normalized, resulting in bandwidth jitter b2, latency jitter t2, and frame-by-frame stuttering rate s2. A weighted average of these normalized results yields (0.3*b2 + 0.4*t2 + 0.3*s2) / 3. Since smaller values ​​indicate smaller bandwidth jitter, latency jitter, and frame-by-frame stuttering rate, signifying more stable channel transmission, the metric with the smallest calculated value is considered the optimal application metric.

[0094] In other possible implementations, under the interference conditions corresponding to the aforementioned interference information, after the STA measures the application metrics based on different network access parameter groups, for each application metric measured based on the network access parameter group, the STS can select application metrics with a priority greater than a priority threshold from the application metrics measured in each network access parameter group. These selected application metrics can be normalized, and the normalization results can be weighted and averaged to obtain the weighted average value corresponding to these application metrics. The STA can determine the application metric corresponding to the smallest weighted average value as the optimal application metric.

[0095] In some possible implementations, the aforementioned priority threshold can be preset or dynamically set, and this application does not impose any restrictions on this.

[0096] For example, the STA can set the priority of bandwidth jitter to 5, latency jitter to 4, and frame-by-frame stuttering rate to 3. The STA can also set a priority threshold of 3. In this case, the STA determines that the application metrics with a priority higher than this threshold are bandwidth jitter and latency jitter. Furthermore, the STA can normalize these two application metrics and perform a weighted average on the normalization result to obtain the weighted average value corresponding to these application metrics. The STA can then determine the application metric corresponding to the smallest weighted average value as the optimal application metric.

[0097] It should be understood that this application does not restrict the method of determining the optimal application metrics based on application metrics.

[0098] It should be understood that, under the interference environment corresponding to the above interference information, the network access parameter set corresponding to the best application index is the target network access parameter set.

[0099] It should be understood that the above process is the process by which the STA establishes a mapping relationship between the interference information and the target network access parameter group under the same interference environment. In fact, the STA can also establish mapping relationships between more interference information and the target network access parameter group.

[0100] For example, when the interference information includes the interference level, the STA can establish multiple mapping relationships between interference levels and multiple target network access parameter groups, as shown in Table 3. Table 3 only lists some of the mapping relationships between interference levels and target network access parameter groups, but is not limited to these.

[0101] Table 3

[0102] Interference level Target network access parameter group Level 1 Combination E Level 2 Combination A Level 3 Combination B Level 4 Combination D Level 5 Combination C

[0103] For example, as shown in the second row of Table 3, when the interference level is level 1, the STA determines that the optimal application metric is the application metric corresponding to the server when the STA reconnects to the AP based on combination E and transmits data with the server. Therefore, the STA can determine that when the interference level is level 1, the target network access parameter group is combination E.

[0104] For example, when the interference information includes interference score intervals, the STA can score these intervals to establish a mapping relationship between multiple interference score intervals and multiple target network access parameter groups, as shown in Table 4. Table 4 only lists some of the mapping relationships between interference score intervals and target network access parameter groups, but is not limited to these.

[0105] Table 4

[0106] Interference score range Target network access parameter group [80,100] Combination E [60,80) Combination A [40,60) Combination B [20,40) Combination D [0,20) Combination C

[0107] For example, as shown in the second row of Table 4, when the interference score range is [80, 100], the STA determines that the best application index is the application index corresponding to the server when the STA reconnects to the AP according to combination E and transmits data with the server. Then the STA can determine that when the interference score range is [80, 100], the target network access parameter group is combination E.

[0108] In other possible implementations, when the interference information includes interference level and interference score range, the STA can establish mapping relationships between multiple interference information sets and multiple target network access parameter sets, as shown in Table 5. Table 5 only lists some of the mapping relationships between interference information sets and target network access parameter sets, but is not limited to these.

[0109] Table 5

[0110] Interference level Interference score range Target network access parameter group Level 1 [80,100] Combination E Level 2 [60,80) Combination A Level 3 [40,60) Combination B Level 4 [20,40) Combination D Level 5 [0,20) Combination C

[0111] For example, as shown in the second row of Table 5, when the interference level is level 1 and the interference score range is [80, 100], the STA determines that the best application indicator is the application indicator corresponding to the server when the STA reconnects to the AP according to combination E and transmits data with the server. Then the STA can determine that when the interference level is level 1 and the interference score range is [80, 100], the target network access parameter group is combination E.

[0112] In some possible implementations, the STA can record the above mapping relationship in a local or cloud database, and this application does not impose any restrictions on this.

[0113] In some possible implementations, the STA can look up the corresponding target network access parameter group based on the interference information of the target channel in the above-mentioned mapping relationship between interference information and target network access parameter group. This application does not impose any restrictions on this.

[0115] Furthermore, since the measurement of application metrics such as bandwidth jitter, latency jitter, and frame-by-frame stuttering rate is relatively simple, the process of establishing the above mapping relationship can be improved.
