Description

Technical Field

[0001] This invention relates to the field of wireless network access, and in particular to a method, apparatus, device, and storage medium for signal strength detection in a PON gateway environment. Background Technology

[0002] As users continue to make new demands on home networks, operators are currently addressing users' internet access needs by providing whole-house Wi-Fi coverage through Fiber to the Room (FTTR). When setting up a Wi-Fi network, the best access point (AP) needs to be selected from multiple Wi-Fi access nodes; and during use, access points may switch as needed, resulting in roaming. When a station (STA) roams, it needs to leave its current access point and connect to a target access point. A key factor in this selection process is the signal strength between the STA and the Wi-Fi access points of different APs.

[0003] The primary implementation of the AP acquiring signal strength information between the STA and different Wi-Fi access nodes is the 802.11k protocol. Through this protocol, the STA can report to the AP, allowing the access AP to know which APs are available near the connected STA and their signal strength. However, this method of acquiring signal strength is highly dependent on the STA, and the signal strength reported by the STA is from the STA's perspective; the units of signal strength are not uniform across different STAs, increasing the difficulty for the AP to process data from different STAs. Therefore, a more convenient method for acquiring STA signal strength is needed. Summary of the Invention

[0004] This invention provides a signal strength detection method, apparatus, device, and storage medium in a PON gateway environment, so as to enable the access node (AP) to actively obtain the STA signal strength, and to improve the applicability and efficiency of the method of obtaining the STA signal strength.

[0005] A signal strength detection method in a PON gateway environment, the method being executed by a first access node, includes: Obtain the signal detection mode of the first access node; Based on the detection mode, a request to send a control frame is sent to the STA device, or the STA device is monitored. Based on receiving or listening to the transmit permission control frame sent by the STA device, the signal strength of the STA device is determined. The transmit permission control frame is generated by the STA device in response to the request transmit control frame.

[0006] Preferably, the detection modes include: independent detection mode, simulated independent detection mode, and detection and eavesdropping mode, wherein, Independent detection mode allows each access node in the network to detect the signal strength of the STA device. In a network simulating independent detection mode, there exists a second access node associated with the STA device. The detection and eavesdropping mode allows the target access point to detect the signal strength of the STA device.

[0007] Preferably, the detection mode is an independent detection mode; Based on the detection mode, a request to send a control frame is sent to the STA device, or the STA device is monitored, including: Send a request control frame to the STA device.

[0010] Preferably, based on the judgment result, a request to send a control frame is sent to the STA device, or the STA device is monitored, including: When the determination result is that the first access node is the target access node, a request to send a control frame is sent to the STA device. The request to send a control frame contains the MAC address of the first access node. When the determination result is that the first access node is not the target access node, the STA device is monitored.

[0011] Preferably, determining the STA device signal strength based on receiving or listening to a transmit permission control frame sent by the STA device includes: Based on the signal power that allows the transmission of control frames, determine the received signal strength indication information and signal-to-noise ratio of the STA device; The signal strength of the STA device is determined based on the signal strength indication information and the signal-to-noise ratio.

The determination module is used to determine the signal strength of the STA device based on the received or listened-to transmit control frame. The transmit control frame is generated by the STA device in response to the request transmit control frame.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In one embodiment, such as Figure 1 As shown, a signal strength detection method in a PON gateway environment is provided, including the following steps: S101, Obtain the signal detection mode of the first access node; S102, based on the detection mode, send a request to the STA device to send a control frame, or listen to the STA device; S103, based on receiving or listening to the transmit permission control frame sent by the STA device, determine the signal strength of the STA device. The transmit permission control frame is generated by the STA device in response to the request transmit control frame.

[0019] The first access node is any AP within the FTTR network.

[0020] Among them, the signal detection mode is the pre-set method of obtaining the STA signal strength within the FTTR network. In other words, the first access node obtains the STA signal strength in different ways under different signal detection modes.

[0021] As an example, in step S101, the first access node can determine the signal detection mode corresponding to the first access node by querying its own configuration information, or by querying the master control device of the FTTR network. This disclosure does not limit the method of obtaining the signal detection mode.

[0022] As an example, in step S102, when it is determined that the first access node can send a Request to Send (RTS) frame to the STA device based on the acquired signal detection mode, the first access node sends an RTS frame to the STA device, thereby requesting the STA device to return a Clear to Send (CTS) frame that can be used to calculate the signal strength of the STA device.

[0023] As an example, in step S102, when it is determined that the first access node cannot send an RTS frame to the STA device based on the acquired signal detection mode, it means that there are other APs in the FTTR network that have the ability to send an RTS frame to the STA device. At this time, the first access node can listen to the STA so that when the STA device sends a CTS frame to other APs in response to the RTS frame sent by other devices, it can capture the CTS frame sent by the STA device.

[0024] As an example, in step S103, since the CTS frame sent by the STA contains parameters that can be used to calculate the signal strength of the STA device, the first access node can determine the signal strength of the STA device based on the parameters in the received or heard CTS frame.

[0025] It should be understood that this disclosure does not limit the specific parameters contained in the CTS frame, such as parameters that can indicate signal strength, such as those used to calculate the Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), and Link Quality Indicator (LQI).

[0026] It should be understood that the CTS frame is generated by the STA device in response to the request to send the RTS frame sent by the access node in the FTTR network.

[0027] In summary, the signal strength detection method proposed in this disclosure for a PON gateway environment can be applied to access nodes. The method includes: acquiring the signal detection mode of a first access node; based on the detection mode, sending a request to transmit control frame to the STA device, or listening to the STA device; and determining the signal strength of the STA device based on receiving or listening to the transmit permission control frame sent by the STA device, wherein the transmit permission control frame is generated by the STA device in response to the request to transmit control frame. This method, under different signal detection modes, enables collaborative acquisition of STA signal strength by different access nodes within the network through the access node actively sending control frames to the STA device, without relying on STA reporting, thus simplifying the signal strength acquisition method and improving signal strength acquisition efficiency.

[0028] As an example, there are three modes: independent detection mode, simulated independent detection mode, and detection and eavesdropping mode. In independent detection mode, each access node in the network can detect the signal strength of the STA device. In simulated independent detection mode, there is a second access node associated with the STA device in the network. In detection and eavesdropping mode, the target access point can detect the signal strength of the STA device.

[0029] Specifically, in the independent detection mode, each access node in the FTTR network, regardless of whether it is associated with the STA device, can send an RTS frame to the STA device to determine the signal strength of the STA device based on the CTS frame sent by the STA device in response to the RTS frame.

[0030] In the simulated standalone detection mode, the FTTR network has at least one access node (i.e., the second access node) associated with the STA. When other nodes in the FTTR network (access nodes other than the second access node) want to obtain the CTS frame sent by the STA device, they can use the relevant information of the second access node to simulate the second access node sending an RTS frame to the STA device, so that the STA device responds to the RTS frame by sending a CTS frame. For the second access node, the signal strength of the STA device can be determined by referring to the method in the standalone detection mode.

[0031] In the probe-and-listen mode, since the FTTR network specifies the access node (i.e., the target access node) for direct probe of the STA device, if the first access node is the target access node, the signal strength of the STA device can be determined by referring to the method in the independent probe mode; if the first access node is not the target access node, the STA device can be listened to in order to obtain the CTS frame when the STA device sends a CTS frame, and the signal strength of the STA device can be determined by using the CTS frame.

[0032] As an example, when the first access node's detection mode is independent detection mode, Figure 2 Taking the FTTR system shown as an example, AP1, AP2, and AP3 are three access nodes in the FTTR network. AP1, AP2, and AP3 can be associated with or not associated with the STA device STA1. When the first access node is AP1, AP1 can send an RTS frame to STA1 to request STA1 to reply with a CTS frame. The RTS frame contains the MAC address of AP1 so that STA1 can know that the AP sending the RTS frame is AP1. When the first access node is AP2, AP2 can send an RTS frame to STA1 to request STA1 to reply with a CTS frame. The RTS frame contains the MAC address of AP2 so that STA1 can know that the AP sending the RTS frame is AP2.

[0033] In other words, in standalone probe mode, the AP sending the RTS frame to the STA needs to include its own MAC address to inform the STA of the AP's identity; that is, in standalone probe mode, the first access node can send a request to send control frame to the STA, and the request to send control frame contains the first access node's MAC address. As an example, when the detection mode is simulated standalone detection mode, with Figure 3 Taking the FTTR system shown as an example, AP1, AP2, and AP3 are three access nodes in the FTTR network. AP1 is associated with the STA device STA1. When the first access node is AP1, AP1 can send an RTS frame to STA1 to request STA1 to reply with a CTS frame. The RTS frame contains the MAC address of AP1 so that STA1 can know that the AP sending the RTS frame is AP1. When the first access node is AP2, AP2 can send an RTS frame to STA1 to request STA1 to reply with a CTS frame. The RTS frame contains the MAC address of AP1 so that AP2 can simulate AP1 to send an RTS frame to STA1.

[0034] In other words, in simulated standalone probe mode, when sending RTS frames to the STA device, the MAC address of the AP associated with the STA must be carried in the RTS frame to deceive the STA device into thinking that the RTS frame is sent by the AP associated with the STA device; that is, in simulated standalone probe mode, the first access node can send a request to send control frame to the STA device, and the request to send control frame contains the MAC address of the second access node.

[0035] As an example, when the detection mode is detection and listening mode, with Figure 4 Taking the FTTR system shown as an example, AP1, AP2, and AP3 are three access nodes in the FTTR network. AP1 is the target AP. When the first access node is AP1, AP1 can send an RTS frame to STA1 to request STA1 to reply with a CTS frame. The RTS frame contains the MAC address of AP1 so that STA1 can know that the AP sending the RTS frame is the target AP. When the first access node is AP2 or AP3, since the first access node is not the target AP, the first access node does not have the ability to send an RTS frame to STA1. In this case, the first access node can only listen to STA1 to obtain STA1's CTS frame when STA1 replies with a CTS frame to AP1.

[0036] In other words, in probe-and-sniff mode, only the target access node can send RTS frames to the STA device to receive the CTS frame sent by the STA device in response to the RTS frame. Other access nodes in the FTTR network, besides the target access node, can only snoop on the STA device to obtain STA frames. That is, other access nodes besides the target access node do not have the ability to trigger the STA device to send CTS frames. In probe-and-sniff mode, the first access node needs to determine whether it is the target access node. Based on the determination result, it sends a request to send a control frame to the STA device or snoops on the STA device. Specifically, when the determination result is that the first access node is the target node, it sends a request to send a control frame to the STA device, which contains the MAC address of the first access node; when the determination result is that the first access node is not the target node, it snoops on the STA device.

[0037] It should be understood that this disclosure does not limit the method of determining whether the first access node is the target access node. For example, it can determine whether it is the target access node by querying its own configuration information to see if its own configuration information meets the configuration information of the target access node (such as whether it is consistent with the device number of the target access node). Alternatively, it can determine whether it is the target access node by querying the master control device of the FTTR network.

[0038] As an example, such as Figure 5 As shown, step S103, which determines the signal strength of the STA device based on receiving or listening to the transmit permission control frame sent by the STA device, includes: S501, based on the signal power that allows the transmission of control frames, determines the received signal strength indication information and signal-to-noise ratio corresponding to the STA device; S502 determines the signal strength of the STA device based on signal strength indication information and signal-to-noise ratio.

[0039] As an example, in step S501, the received signal strength indication information RSSI and signal-to-noise ratio SNR corresponding to the CTS frame can be calculated according to a preset mapping relationship by the signal power corresponding to the CTS frame when receiving or listening to the CTS frame.

[0040] As an example, in step S502, the signal strength indication information RSSI and the signal-to-noise ratio SNR can be fused (e.g., by weighted summation), and the fused result can be determined as the signal strength between the STA devices.

[0041] It should be understood that the above method for determining the signal strength of the STA device is only an example. The CTS frame sent by the STA device may also contain other information so that the first access node can determine the signal strength between the first access node and the STA device based on the information contained in the CTS frame.

[0042] In summary, the method disclosed herein has the following beneficial effects: 1. Low dependence on STA: The AP actively detects the STA signal strength, no longer relying on STA reporting.

[0043] 2. No protocol compatibility issues: It uses the standard 802.11 control protocol for interaction (RTS frames and CTS frames), so there are no complicated protocol compatibility issues.

[0044] 3. No signal strength compatibility issues: All acquired STA signal strengths are from the AP's perspective; the units are naturally uniform and do not require conversion for different STAs.

[0045] 4. AP Cooperative Acquisition: By using different rules in different modes to enable APs to acquire CTS frames, APs within the network can cooperate and avoid data loss caused by signal conflicts.

[0046] In one embodiment, a STA device signal strength detection device is provided, which corresponds one-to-one with the signal strength detection method in the PON gateway environment described in the above embodiments. For example... Figure 6 As shown, the STA equipment signal strength detection device includes an acquisition module 610, a processing module 620, and a determination module 630. Detailed descriptions of each functional module are as follows: The acquisition module 610 is used to acquire the signal detection mode of the first access node; The processing module 620 is used to send a request to the STA device to send a control frame based on the detection mode, or to listen to the STA device. The determination module 630 is used to determine the signal strength of the STA device based on receiving or listening to the transmit permission control frame sent by the STA device. The transmit permission control frame is generated by the STA device in response to the request transmit control frame.

[0047] As an example, signal detection modes include: independent detection mode, simulated independent detection mode, and detection and eavesdropping mode, wherein, Independent detection mode allows each access node in the network to detect the signal strength of the STA device. In a network simulating independent detection mode, there exists a second access node associated with the STA device. The detection and eavesdropping mode allows the target access point to detect the signal strength of the STA device.

[0048] As an example, in the standalone detection mode, the processing module 620 is further configured to send a request to send a control frame to the STA device, the request to send the control frame containing the MAC address of the first access node.

[0049] As an example, in the simulated standalone detection mode, the processing module 620 is further configured to send a request to send a control frame to the STA device, the request to send the control frame containing the MAC address of the second access node.

[0050] As an example, the detection mode is a detection and listening mode, and the processing module 620 is also used to determine whether the first access node is the target access node. Based on the judgment result, a request to send a control frame is sent to the STA device, or the STA device is monitored.

[0051] As an example, the processing module 620 is also used to send a request to send a control frame to the STA device when the determination result is that the first access node is the target node. The request to send a control frame contains the MAC address of the first access node. When the determination result is that the first access node is not the target node, the STA device is monitored.

[0052] As an example, the determining module 630 is also used to determine the received signal strength indication information and signal-to-noise ratio corresponding to the STA device based on the signal power that allows the transmission of control frames; The signal strength of the STA device is determined based on the signal strength indication information and the signal-to-noise ratio.

[0053] In summary, the STA device signal strength detection device proposed in this disclosure includes: an acquisition module for acquiring the signal detection mode of a first access node; a processing module for sending a request transmission control frame to the STA device or listening to the STA device based on the detection mode; and a determination module for determining the signal strength of the STA device based on receiving or listening to a transmission permission control frame sent by the STA device, wherein the transmission permission control frame is generated by the STA device in response to the request transmission control frame. The device of this disclosure, under different signal detection modes, enables collaborative acquisition of STA signal strength by different access nodes within the network by actively sending control frames to the STA device, without relying on STA reporting, thus simplifying the signal strength acquisition method and improving the efficiency of signal strength acquisition.
