For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0044] Currently, mainstream applications usually collect network information through the application layer of the client installed on the terminal, which can perceive the network environment around the terminal carrying the application to a certain extent, but lack the understanding of the overall network environment, such as the system capacity of the cell where the terminal is located, the remaining resources, and the surrounding interference information. The information related to the overall surrounding network environment can potentially provide a more accurate description of the network status for the application.

[0045] Therefore, a new network information opening method, device, electronic device and computer-readable medium are needed.

[0046] Figure 1 A schematic diagram showing an exemplary system architecture to which the network information disclosure method or device according to an embodiment of the present disclosure can be applied.

[0047] like Figure 1 As shown, the system architecture 100 may include one or more of the first terminal devices 101, 102, 103, a network 104 and an access point (AP) 105. The access point 105 refers to a device for the first user terminal of a wireless local area network user to access the network. The first terminal devices 101, 102 and 103 belong to the terminals (STA) in the wireless local area network. The network 104 may be a wireless communication link.

[0048] It should be understood that Figure 1The number of first terminal devices, networks and access points in the embodiment is only for illustration. Any number of first terminal devices, networks and access points may be provided according to implementation requirements.

[0049] The user can use the first terminal devices 101, 102, 103 to interact with the access point 105 through the network 104 to receive or send messages, etc. The first terminal devices 101, 102, 103 can be various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, portable computers, desktop computers, wearable devices, virtual reality devices, smart homes, etc.

[0050] For example, the first terminal device 103 (or the terminal device 101 or 102) can obtain the network information opening related information sent by the access point 105; the network information opening related information includes one or more of the following: wireless resource occupation related information, wireless resource use related information; wherein the wireless resource occupation related information at least includes: duty cycle, the corresponding frequency band of the duty cycle, and the competition information of the adjacent cells, and the competition information of the adjacent cells indicates that the cell where the access point is located is interfered by the adjacent cells; the wireless resource use related information at least includes: the cell-level wireless resource use information where the access point is located. In this way, the network information opening in the wireless local area network is realized, so that the first terminal device can make better decisions on wireless network changes.

[0051] Figure 2 A flowchart of a network information opening method according to an embodiment of the present disclosure is schematically shown. The method provided by the embodiment of the present disclosure can be Figure 1 In the embodiment, the first terminal devices 101, 102, and 103 in the wireless local area network are processed. In the following embodiment, the first terminal device 101 is used as an execution subject for illustration, but the present disclosure is not limited to this.

[0052] like Figure 2 As shown, the network information opening method provided by the embodiment of the present disclosure may include the following steps.

[0053] In step S210, network information opening related information sent by the access point is obtained.

[0054] In the embodiment of the present disclosure, the access point may send network information opening related information in a broadcast or unicast manner. The access point is a device in a wireless local area network for a mobile device to access the network. The mobile device is, for example, the first terminal device in the embodiment of the present disclosure. An access point may be wirelessly connected to other access points to extend the coverage of the network.

[0055] The first terminal device in the embodiment of the present disclosure may be associated with an access point.

[0056] In the embodiment of the present disclosure, the network information disclosure related information includes one or more of the following:

[0057] Information related to wireless resource occupation and wireless resource usage;

[0058] The wireless resource occupation related information includes at least: a duty cycle, a frequency band corresponding to the duty cycle, and contention information of adjacent cells. The contention information of adjacent cells indicates the interference situation of the cell where the access point is located by the adjacent cells.

[0059] The duty cycle refers to the ratio of the duration of wireless resource occupation to the total duration of statistics in the corresponding frequency band (such as 2.4GHz, 5GHz, etc.) within the sensing range of the access point in a unit of time. The higher the duty cycle, the longer or more frequently the access point and the surrounding wireless resources are occupied. The duty cycle is directly related to the working frequency band of the access point, and the duty cycle of different working frequency bands of the access point may be different.

[0060] The contention information of the neighboring cells may include: the number of the neighboring cells, the duty cycle of the neighboring cells, etc.

[0061] The wireless resource usage related information at least includes: wireless resource usage information at the cell level where the access point is located. The wireless resource usage information at the cell level is, for example, the cell level network rate, that is, the overall rate of the MAC layer.

[0062] It should be noted that the network information opening related information can be a specific value, such as the actual percentage of the duty cycle, the sum of the cell-level network rate (such as Mbps). In order to save the amount of data consumed by network transmission and improve transmission efficiency, the network information opening related information can also be normalized to multiple gears, such as duty cycle>=75%, 50%<=duty cycle<75%, 25%<=duty cycle<50%, duty cycle<25%. In this way, only two bits are needed to indicate the network information opening related information.

[0063] The network information opening method provided in the embodiment of the present disclosure can realize network information opening in a wireless local area network by receiving network information opening related information sent to it by an access point by a first terminal device. The network information opening related information sent by the access point can facilitate the first terminal device to grasp the real-time changes of the network according to the wireless resource occupation related information and the wireless resource use related information, and avoid the network freeze caused by the first terminal device being unable to know the real-time status of the network.

[0064] In step S220, the network status of the first terminal device is determined according to the network information opening related information.

[0065] In the disclosed embodiment, the network state of the first terminal device may be determined according to the network information opening related information. The network state may include network state parameters, such as rate, delay, modulation and coding strategy, etc.

[0066] In step S230, according to the network status parameters in the network status, an adaptive mechanism is triggered to adjust the network transmission parameters of the first terminal device.

[0067] In the embodiments of the present disclosure, the network status parameters may be, for example, delay, rate, and bit rate. The adaptive mechanism is, for example, a bit rate adaptive mechanism. Taking the video on demand application as an example, when the network status parameters meet the preset conditions, the video transmission bit rate as a network transmission parameter can be automatically adjusted according to the bit rate adaptive mechanism to reduce the video transmission bit rate, so as to reduce the network resources consumed by the video transmission, thereby avoiding the probability of video freeze. Among them, the preset conditions include, for example, the rate drop value is greater than the rate drop threshold, the delay is greater than the delay threshold, and the modulation and coding strategy drop value is greater than the modulation and coding strategy drop threshold.

[0068] In the network information opening method provided by the embodiment of the present disclosure, the first terminal device receives the network information opening related information sent to it by the access point, which can realize the network information opening in the wireless local area network. At the same time, the first terminal device determines the network status of the first terminal device based on the network information opening related information, can understand the change of the network status in real time according to the network status parameters in the network status, and triggers the adaptive mechanism based on the network status parameters to adjust the network transmission parameters of the first terminal device to adapt to the change of the network status, which can realize the network optimization of the first terminal, and then realize the first terminal device to make adaptive network decisions for the changes of the wireless network, avoiding the network delay caused by the mismatch between the network and the demand.

[0081] In an exemplary embodiment, when the first message is a data frame, the network information opening related information is carried in a MAC frame header or a physical frame header in the data frame.

[0082] In step S330, the time domain characteristics of the network information opening related information are determined according to the time domain information in the multiple segments of network information opening related information, so as to determine the network status of the first terminal device according to the time domain characteristics.

[0083] In the embodiment of the present disclosure, the first message may include multiple segments of network information opening related information, and each segment of network information opening related information includes time domain information in each sending cycle. Among them, the time domain information is used to indicate the sending frequency and characteristics of network information opening related information in the time domain. The time domain information is, for example, the network information opening related information in the past multiple statistical periods, such as the past 100ms, the past 100 to 200ms, etc., relative time, or absolute time.

[0084] In step S340, according to the network status parameters in the network status, an adaptive mechanism is triggered to adjust the network transmission parameters of the first terminal device.

[0087] In step S410, a second message is sent to the access point, where the second message is used to request to obtain network information opening related information; the second message carries a field identifier of the required network information opening related information.

[0088] In the embodiment of the present disclosure, the field identifier of the required network information opening related information is the field in the aforementioned wireless resource occupation related information and wireless resource use related information.

The sending period is used to negotiate the time domain information involved in the subsequent sending of the third message, for example, it can indicate that the subsequent third message is sent periodically and its sending frequency. For another example, the third message can also be sent only once (i.e., triggered sending, the access point will send the third message only after successfully receiving the second message).

[0108] In step S520, the third message returned by the access point according to the sending cycle is received.

[0109] In step S530, the time domain characteristics of the network information opening related information are determined according to the time domain information in the multiple segments of network information opening related information, so as to determine the network status of the first terminal device according to the time domain characteristics.
