Abstract
Description
Technical Field
[0001] The present application relates to the field of computer technology, and in particular to a configuration method, device, equipment and storage medium for a roaming threshold. Background Art
[0002] In the field of computer technology, a terminal device (Station, STA) accesses a wireless network through a wireless access point (Access Point, AP). When the terminal location changes, from the wireless signal coverage area of one AP to the wireless signal coverage area of another AP, a change in the access AP will occur. This process is called wireless roaming. Wireless roaming includes active roaming and passive roaming.
[0003] In the passive roaming context, when the received signal strength (RSSI) of the terminal is lower than the roaming threshold, the AP first requests the terminal to return the signal quality of the same ESS AP near the current terminal through the 802.11k protocol message. After receiving the measurement report from the STA, the AP selects the best AP from among them and requests the terminal to switch to the best AP through the 802.11v protocol message. The terminal replies to the AP through the 802.11v protocol message whether to accept the roaming guidance.
[0004] However, in the prior art, there are unreasonable situations in the setting of roaming thresholds. In some cases, the roaming threshold is set too high, and the terminal will frequently switch APs, causing the terminal to be in a roaming state before switching to access the AP, resulting in a certain amount of time waste; if the roaming threshold is set too low, the terminal cannot switch APs, resulting in poor signal quality or even signal interruption.

DETAILED DESCRIPTION
[0023] The terms "first", "second", "third", etc. in the specification of this application and the accompanying drawings are used to distinguish different objects rather than to limit a specific order.
[0024] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0025] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given: Terminals are mobile devices connected to a wireless network, such as mobile phones, tablets, and laptops. STAs usually act as clients in a wireless network and communicate with APs (Access Points) through wireless signals to access the network and obtain Internet access.
[0026] AP is the most commonly used device when building a small wireless LAN. AP is equivalent to a bridge connecting wired network and wireless network. Its main function is to connect various wireless network clients together, and then connect the wireless network to Ethernet, so as to achieve the purpose of network wireless coverage. AP is also responsible for collecting neighbor AP information and reporting neighbor AP information to AC.
[0027] AC (Access Controller) is a network device used to centrally control controllable wireless APs in a local area network. AC is the core of a wireless network and is responsible for managing all wireless APs in the wireless network. AP management includes: storing AP data information, calculating path loss, calculating roaming thresholds, and issuing roaming thresholds to APs.
[0028] At present, there are unreasonable situations in the setting of roaming thresholds. In some cases, if the roaming threshold is set high, the terminal will frequently switch APs, causing the terminal to be in a roaming state before switching to the access AP, resulting in a certain amount of time waste; if the roaming threshold is set low, the terminal cannot switch APs, resulting in poor signal quality or even signal interruption. In view of this, an embodiment of the present application provides a method for configuring a roaming threshold, in which the AC obtains data information of a target AP and data information of a first neighbor AP of the target AP, calculates the path loss between the target AP and the first neighbor AP of the target AP according to the RSSI value of the target AP and the transmit power of the first neighbor AP of the target AP, and then calculates the roaming threshold of the target AP according to the path loss between the target AP and the first neighbor AP of the target AP, and the AC sends the roaming threshold of the target AP to the target AP to configure the roaming threshold of the target AP, obtains the neighbor AP of the first neighbor AP by the same method, and calculates the roaming threshold of the first neighbor AP to configure the roaming threshold of the first neighbor AP. It can be seen that the present application dynamically calculates the state of the target AP to obtain a reasonable roaming threshold, so that the terminal can reduce the number of AP switching and roaming states, maintain a good and uninterrupted signal state, and improve the user experience.
[0029] In order to make the technical solution of the present application clearer and easier to understand, a method for configuring a roaming threshold provided by an embodiment of the present application is introduced below in conjunction with a flow chart. Figure 1 As shown, the figure is a flowchart of a method for configuring a roaming threshold provided in an embodiment of the present application.
[0030] In the embodiment of the present application, the target AP may be one or more, and the target AP and the neighboring APs of the target AP are calculated according to the state of the target AP to obtain a reasonable roaming threshold. The configuration method of the roaming threshold includes: S101. An AC obtains data information of a target AP and data information of a first neighbor AP.
[0031] The AP collects data information of the first neighbor AP and reports the data information of the first neighbor AP to the AC. The AC receives the data information of the first neighbor AP and stores it in a database. The data information includes a MAC address, an RSSI value, and a transmission power.
[0032] Among them, the target AP can represent one or more APs, and the target AP represents some APs whose status changes among all APs. The first neighbor AP represents the AP whose data information such as transmission power changes due to the change of the target AP status, that is, the neighbor AP affected by the target AP, which can be several APs or all APs.
[0033] The MAC address of an AP refers to the media access control address of the AP, also known as the hardware address. The MAC address is used to uniquely identify a device in the network to ensure that data packets can be accurately sent to the target device; the RSSI (Received Signal Strength Indicator) of an AP is the received signal strength indicator, which is used to measure the signal strength of a location within the coverage of a wireless network. The larger the RSSI value, the better the received signal quality. Generally speaking, an RSSI value between -50dBm and -70dBm is considered to be good signal quality; the transmit power refers to the power of the radio frequency transmitted by the AP, which is used to measure the ability of the AP to send signals. The transmit power is usually measured in dBm. The larger the transmit power value of the AP, the wider the coverage range of the AP, and the stronger the signal that the wireless device can receive.
[0034] When the state of the target AP switches from offline to online, the AC needs to calculate the data information of the first neighbor AP, which is the neighbor AP of the target AP, obtain the RSSI value of the target AP and the transmission power of the first neighbor AP, and update the neighbor AP table of the target AP, that is, the first neighbor AP table, and the neighbor AP table of the neighbor AP of the target AP, that is, the second neighbor AP table.
[0035] When the state of the target AP switches from the online state to the offline state, the AC obtains the data information of the first neighbor AP and the data information of the second neighbor AP, and the second neighbor AP is the neighbor AP of the first neighbor AP. The RSSI value of the first neighbor AP and the transmit power of the second neighbor AP are obtained, and the neighbor AP table of the target AP, i.e., the first neighbor AP table, and the neighbor AP table of the neighbor AP of the target AP, i.e., the second neighbor AP table, are updated.
[0036] When the state of the target AP is converted to the offline state, the first neighbor AP is affected because the data information of the first neighbor AP is affected, which in turn affects the neighbor AP of the first neighbor AP, that is, the second neighbor AP.
[0037] Since the state of the target AP may change from online to offline and from offline to online, the data information of the surrounding neighbor APs will change. Therefore, after the target AP is online, it is necessary to calculate the RSSI value of the target AP and the transmit power of the first neighbor AP, and update the first neighbor AP table and the second neighbor AP table; after the target AP is offline, calculate the RSSI value of the first neighbor AP and the transmit power of the second neighbor AP, and update the first neighbor AP table and the second neighbor AP table.
[0038] S102: The AC calculates a path loss between the target AP and the first neighbor AP according to the RSSI value of the target AP and the transmit power of the first neighbor AP.
[0039] Based on the RSSI value of the target AP and the transmit power of the first neighbor AP, the path loss between the target AP and the first neighbor AP can be calculated. The path loss between the target AP and the first neighbor AP refers to the loss of the signal on the wireless propagation path between the two. This loss is affected by many factors, including the radiation diffusion of the transmit power, the propagation characteristics of the channel, the propagation distance, the atmospheric conditions, the terrain, and obstacles such as buildings. Path loss is an important indicator that reflects the change in the mean value of the received signal power in a macroscopic range.
[0040] The calculation formula of the path loss between the target AP and the first neighbor AP is as follows:
[0041] in, is the path loss between the target AP and the first neighbor AP, is the RSSI value of the target AP, is the transmit power of the first neighbor AP.
[0042] Similarly, according to the RSSI value of the first neighbor AP and the transmit power of the second neighbor AP, the path loss between the first neighbor AP and the second neighbor AP can be obtained.
[0043] S103 . The AC calculates a roaming threshold of the target AP according to a path loss between the target AP and the first neighbor AP.
[0044] The roaming threshold of the target AP refers to a critical value of the wireless signal strength. When the signal strength of the current AP received by the wireless client is lower than this threshold, the client will start to find and switch to another AP with a stronger signal. Setting the roaming threshold too high or too low may lead to frequent roaming, which not only affects network performance, but also may increase the power consumption of the wireless client.
[0045] In this application, according to the state transition of the target AP, the data information of the neighboring APs of the target AP is obtained in real time through the AP, and then the roaming threshold of each AP is calculated, so that the terminal can freely choose whether to switch to the access AP when accessing the AP, without being unable to switch or frequently switching due to the roaming threshold. The setting of the roaming threshold is intended to ensure that the wireless client can automatically and smoothly switch to another AP when the signal is weak, reduce the situation where the terminal is in roaming, and thus maintain the continuity and stability of the network.
[0046] According to the path loss between the target AP and the first neighbor AP, the roaming threshold of the target AP is calculated by the following calculation method:
[0047] in, is the roaming threshold of the target AP, is the transmit power of the terminal, is the path loss between the target AP and the first neighbor AP, is a fixed adjustment value, which is determined according to the density of APs.
[0048] When APs are densely populated, the fixed adjustment value A is increased accordingly according to the density. The number of APs is set to 7. Since one new AP is put online, the current number of APs becomes 8, so the fixed adjustment value A value of 2dB is added to the formula. Since two new APs are put online, the current number of APs becomes 9, so the fixed adjustment value A value of 4dB is added to the formula. In the embodiment of the present application, the value of the fixed adjustment value A is only used as an example, and the specific value of the fixed adjustment value A may vary in different situations.
[0049] Similarly, the roaming threshold of the first neighbor AP can be obtained according to the path loss between the first neighbor AP and the second neighbor AP.
[0050] S104: The AC sends the roaming threshold of the target AP to the target AP.
[0051] The AC sends the roaming threshold of the target AP to the target AP and sends the roaming threshold of the first neighbor AP to the first neighbor AP, so as to configure the roaming threshold of the target AP and the roaming threshold of the first neighbor AP.
[0052] Through the above process, the roaming threshold of each AP can be calculated. After the terminal moves, if the AP detects that the RSSI value of the AP to which the terminal is connected is continuously lower than the roaming threshold, the terminal is triggered to provide feedback to the AP. The AP selects the best AP among all APs, that is, the AP with the best signal quality, and guides the terminal to access the best AP, thereby achieving roaming. The terminal will choose whether to access the best AP based on the current situation.
[0053] Based on the above content, AC obtains the data information of the target AP and the data information of the first neighbor AP of the target AP, calculates the path loss between the target AP and the first neighbor AP of the target AP according to the RSSI value of the target AP and the transmission power of the first neighbor AP of the target AP, and then calculates the roaming threshold of the target AP according to the path loss between the target AP and the first neighbor AP of the target AP. AC sends the roaming threshold of the target AP to the target AP to configure the roaming threshold of the target AP, obtains the neighbor AP of the first neighbor AP by the same method, and calculates the roaming threshold of the first neighbor AP to configure the roaming threshold of the first neighbor AP. It can be seen that the present application dynamically calculates the state of the target AP to obtain a reasonable roaming threshold, so that the terminal can reduce the number of AP switching and the roaming state, keep the signal state good and uninterrupted, and improve the user experience.
[0054] The present application also provides a configuration device for a roaming threshold, such as Figure 2 As shown, the figure is a schematic diagram of a roaming threshold configuration device provided in an embodiment of the present application.

[0055] In some possible implementations, the calculation module 202 is specifically configured to calculate the path loss between the target AP and the first neighbor AP by using the following formula:
[0056] in, is the path loss between the target AP and the first neighbor AP, is the RSSI value of the target AP, is the transmit power of the first neighbor AP.
