[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0028] It should be noted that although the functional modules are divided in the device schematic diagram, and the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a manner different from the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and above-described drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0029] In the embodiments of the present application, the words "further", "exemplarily" or "optionally" are used to represent as an example, illustration or description, and should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. The words "further", "exemplarily" or "optionally" are used to present the related concept in a specific manner.

[0030] Fiber to the Room (FTTR) is composed of a master device, a slave device and an indoor optical fiber distributed network. FTTR is based on a Point to Multiple Point (P2MP) physical topology structure, and a master device is deployed at a home / small micro enterprise access point position and serves as the center to build a home / small micro enterprise all-optical network. The master device is connected to an OLTPON port at the local end and is connected to multiple slave devices indoors. The slave devices can be extended to the areas required by users according to the layout of the home / small micro enterprise to provide network coverage for each area and achieve high-quality network. Each Access Point (AP) has a Basic Service Set (BSS), and there can be multiple BSSs in the same location due to the shared medium, and the BSSs can overlap to form an Overlapping Basic Service Set (OBSS). Therefore, how to solve the problem of multiple BSSs in the same location and the possible overlap of the BSSs to form an OBSS is the main problem faced by the industry at present.

[0031] Please refer to FIG. 1, which is a structural diagram of an FTTR provided by the related art. Station 1 (STA1) is associated with AP1, but since it is at the edge of BSS1 and BSS2 at the same time, it needs to participate in air interface competition of the areas served by BSS1 and BSS2 at the same time. In this case, the opportunity of STA1 to obtain a transmission time window will be greatly reduced, resulting in a decrease in throughput, an increase in latency, and a significant damage to user experience, especially when STA1 is performing a Real Time Application (RTA). In addition, if AP2 uses “aggressive” EDCA parameters under the Enhanced Distributed Channel Access (EDCA) competition mechanism to maximize the air interface to ensure the business on the AP, the communication environment of STA1 will be even worse.

[0032] Please refer to FIG. 2, which is another structural diagram of an FTTR provided by the related art. The current protocol lacks an effective EDCA parameter synchronization mechanism, which makes it difficult to guarantee the communication effect of high-priority business, especially a Real Time Application (RTA). Even if the BSS1 and BSS2 nodes know the existence of each other in the FTTR networking scenario, they cannot know that the other party has a Very Important Person (VIP) business that needs high priority. In particular, when the VIP business is located on STA1 and STA2, the OBSS cannot even know its existence.

[0033] Based on this, the embodiment of the present application provides an enhanced distributed channel access (EDCA) parameter configuration method, which aims to dynamically configure EDCA parameters, so as to avoid the OBSS situation that BSSs may overlap when multiple BSSs appear near the same location.

[0034] Passive optical network (PON): Passive optical network refers to an optical fiber distribution network (ODN) between an optical line terminal (OLT) and an optical network unit (ONU), without any active communication equipment. One end of the OLT is connected to the upper layer network to complete the uplink access of the PON. The upper layer network can be an internet protocol (IP) backbone network or a public switched telephone network (PSTN). The other end of the OLT is connected to the user terminal device through the ODN to complete the downlink transmission of the PON, and realize the functions of control, management and ranging of the user terminal device. The user terminal device can be an ONU. One end of the user terminal device is connected to the OLT through the ODN, and the other end of the user terminal device is connected to other terminal devices, such as computers, fixed phones, etc. The ONU is used in cooperation with the OLT to realize the functions of Ethernet layer 2 and layer 3, and provide voice, data and multimedia services for users. For example, the ONU can realize the following functions: selecting to receive data sent by the OLT; responding to the management command issued by the OLT and making corresponding adjustments; buffering Ethernet data of users and sending to the uplink in the sending window allocated by the OLT; and other user management functions.

Therefore, the slave device can update the EDCA parameter of itself according to the EDCA update information corresponding to the slave device included in the first EDCA parameter configuration frame, so as to avoid the OBSS situation that the BSSs may overlap when multiple BSSs appear near the same location.

[0059] It should be noted that the slave device of the present application can send a configuration request frame to the master device through the received second configuration trigger frame, so as to obtain the first EDCA parameter configuration parameter, and then update the EDCA parameter of the slave device according to the first EDCA parameter configuration parameter.

[0070] It should be noted that the first EDCA parameter configuration frame of the present application further includes second validity period information, and the second validity period information is used to indicate the validity period of the EDCA update information.

[0071] It can be understood that, by the second validity period information, the slave device can update its own EDCA parameters within the validity period. Only within the validity period, the slave device can update its own EDCA parameters. In addition, if there is no second validity period information, the slave device may constantly try to receive and process expired EDCA update information, which not only occupies the processing resources of the slave device, but also may cause network congestion. Therefore, by the second validity period information, the slave device can quickly identify and discard the expired update information, avoiding the waste of resources.

[0087] For example, in an embodiment, first, the master device sends a first configuration trigger frame to the slave device, the first configuration trigger frame being used to instruct the slave device to send a configuration request frame to the master device; second, the master device receives the configuration request frame from the slave device; third, other slave devices existing OBSS with the slave device are determined according to the first peripheral AP information and the first RSSI, and the slave device and the other slave devices existing OBSS with the slave device are determined as target slave devices, and EDCA update information corresponding to the target slave devices is determined according to the configuration request frame; and finally, a first EDCA parameter configuration frame is sent to each target slave device, wherein the first EDCA parameter configuration frame includes the EDCA update information corresponding to the target slave device, and the EDCA update information is used for the corresponding slave device to update its own EDCA parameter. Therefore, each target slave device updates its own EDCA parameter according to the EDCA update information corresponding to the target slave device included in the first EDCA parameter configuration frame, so as to avoid the situation that when multiple BSSs exist in the same location, the BSSs may overlap to generate OBSS.

[0088] In a possible embodiment, regarding the step S220 of determining at least one target slave device according to the configuration request frame, the EDCA parameter configuration method further includes a step S260:

[0089] Step S260, when it is determined that the slave device exists RTA service according to the first RTA service mark, other slave devices existing OBSS with the slave device are determined according to the first peripheral AP information and the first RSSI, and the slave device and the other slave devices existing OBSS with the slave device are determined as target slave devices.

[0090] It should be noted that the master device of the embodiment of the present application can determine whether the slave device exists RTA service according to the first RTA service mark, and when the slave device exists RTA service, other slave devices existing OBSS with the slave device are determined according to the first peripheral AP information and the first RSSI, and the slave device and the other slave devices existing OBSS with the slave device are determined as target slave devices.

[0091] Exemplarily, in an embodiment, first, the master device sends a first configuration trigger frame to the slave device, the first configuration trigger frame being used to instruct the slave device to send a configuration request frame to the master device; second, the master device receives the configuration request frame from the slave device; third, when it is determined according to the first RTA service mark that the slave device has RTA service, and according to the first peripheral AP information and the first RSSI that there is other slave device having OBSS with the slave device, the slave device and the other slave device having OBSS with the slave device are determined as target slave devices, and the EDCA update information corresponding to the target slave devices is determined according to the configuration request frame; and finally, a first EDCA parameter configuration frame is sent to each target slave device, wherein the first EDCA parameter configuration frame comprises the EDCA update information corresponding to the target slave device, and the EDCA update information is used for the corresponding slave device to update its own EDCA parameter. Therefore, each target slave device updates its own EDCA parameter according to the EDCA update information corresponding to the target slave device included in the first EDCA parameter configuration frame, so as to avoid the case that when there are multiple BSSs in the same location, the BSSs may overlap to generate OBSS.

[0092] It should be noted that the EDCA update information of the present application comprises at least one of the following: minimum contention window CWmin update information, maximum contention window CWmax update information, transmission opportunity TXOP update information, and arbitration inter-frame space number AIFSN update information. The content of the EDCA update information is not limited in the embodiments of the present application.

[0093] In a possible embodiment, regarding the determination process of the EDCA update information corresponding to the target slave device in step S220, the enhanced distributed channel access EDCA parameter configuration method further comprises steps S270-S280:

[0094] Step S270, determining the number of slave devices having RTA service according to the received first RTA service mark.

[0095] Step S280, determining the EDCA update information according to the number of slave devices.

[0096] It should be noted that the master device of the embodiments of the present application can determine the number of slave devices having RTA service according to the received first RTA service mark, so as to determine the EDCA update information according to the number of slave devices.

[0097] It can be understood that the master device of the embodiments of the present application can determine the number of slave devices having RTA service according to the first RTA service mark, so as to determine the EDCA update information according to the number of slave devices, and then the target slave device can update its own EDCA parameter according to the EDCA update information.

[0098] In a possible embodiment, in relation to step S280, the EDCA parameter configuration method further comprises steps S281-S284:

[0099] Step S281, determining a first CWmin value according to the number of slave devices and a preset first parameter.

[0100] Step S282, determining a second CWmin value according to the first CWmin value and a preset second parameter.

[0101] Step S283, updating the CWmin of the target slave device with the first CWmin value as the CWmin update information of the target slave device with RTA service.

[0102] Step S284, updating the CWmin of the target slave device with the second CWmin value as the CWmin update information of the target slave device without RTA service.

[0103] It should be noted that, first, the master device of the embodiment of the present application can determine a first CWmin value according to the number of slave devices and a preset first parameter; second, the master device of the embodiment of the present application can determine a second CWmin value according to the first CWmin value and a preset second parameter; third, the master device of the embodiment of the present application can update the CWmin of the target slave device with the first CWmin value as the CWmin update information of the target slave device with RTA service; and finally, the master device of the embodiment of the present application can update the CWmin of the target slave device with the second CWmin value as the CWmin update information of the target slave device without RTA service.

[0104] It can be understood that the CWmin update information of the target slave device with RTA service is different from that of the target slave device without RTA service in the embodiment of the present application, the CWmin update information of the target slave device with RTA service is the first CWmin value, and the CWmin update information of the target slave device without RTA service is the second CWmin value.

[0105] For example, the master device of the embodiment of the present application can determine whether the slave device has RTA service according to the first RTA service flag, when the slave device has RTA service, determine a first CWmin value according to the number of slave devices and a preset first parameter, and update the CWmin of the target slave device with the first CWmin value as the CWmin update information of the target slave device; and when the slave device does not have RTA service, determine a second CWmin value according to the first CWmin value and a preset second parameter, and update the CWmin of the target slave device with the second CWmin value as the CWmin update information of the target slave device.

[0106] It should be noted that the first CWmin value can be calculated by the formula CW min,RTA = min(N RTA +a, b), and the second CWmin value can be calculated by the formula CWmin,non-RTA =min(2*CW min,RTA ,d), where CW min,RTA is the first CWmin value, N RTA is the number of slave devices, a and b are the first parameters, and d is the second parameter.

[0107] It can be understood that the above-mentioned first parameter and second parameter are preset fixed values ​​and can be set according to actual needs. The embodiment of the present application does not specifically limit the specific values ​​of the first parameter and the second parameter.

[0108] In a possible embodiment, regarding the above step S280, the enhanced distributed channel access EDCA parameter configuration method further includes steps S285 to S288:

[0109] Step S285: Determine a first AIFSN value according to the number of slave devices and a preset third parameter.

[0110] Step S286: Determine a second AIFSN value according to the number of slave devices and a preset fourth parameter, where the fourth parameter is different from the third parameter.

[0111] Step S287: Use the first AIFSN value as the AIFSN update information of the target slave device with the RTA service.

[0112] Step S288: Use the second AIFSN value as the AIFSN update information of the target slave device for which the RTA service does not exist.

[0113] It should be noted that, first, the master device of the embodiment of the present application can determine the first AIFSN value based on the number of slave devices and a preset third parameter; second, the master device of the embodiment of the present application can determine the second AIFSN value based on the number of slave devices and a preset fourth parameter, wherein the fourth parameter is different from the third parameter; thirdly, the master device of the embodiment of the present application uses the first AIFSN value as the AIFSN update information of the target slave device with RTA service; finally, the master device of the embodiment of the present application uses the second AIFSN value as the AIFSN update information of the target slave device without RTA service.

[0114] It can be understood that in the embodiment of the present application, the AIFSN update information of the target slave device with RTA service is different from that of the target slave device without RTA service. The AIFSN update information of the target slave device with RTA service is the first AIFSN value, and the AIFSN update information of the target slave device without RTA service is the second AIFSN value.

[0115] Exemplarily, the master device of an embodiment of the present application can determine whether the slave device has RTA service based on the first RTA service mark. When the slave device has RTA service, the first AIFSN value is determined based on the number of slave devices and a preset third parameter, and the first AIFSN value is used as the AIFSN update information of the target slave device; when the slave device does not have RTA service, the second AIFSN value is determined based on the number of slave devices and a preset fourth parameter, and the second AIFSN value is used as the AIFSN update information of the target slave device.

[0116] It can be understood that the above-mentioned third parameter and fourth parameter are preset fixed values ​​and can be set according to actual needs. Among them, the fourth parameter is different from the third parameter. The embodiment of the present application does not specifically limit the specific values ​​of the third parameter and the fourth parameter.

[0117] It should be noted that the first EDCA parameter configuration frame of the present application further includes second validity period information, and the second validity period information is used to indicate the validity period of the EDCA update information.

[0118] It can be understood that, through the second validity period information, the slave device can update its own EDCA parameters within the validity period, and only within the validity period can the slave device update its own EDCA parameters; in addition, if there is no second validity period information, the slave device may continuously attempt to receive and process expired EDCA update information, which will not only occupy the processing resources of the slave device, but also may cause network congestion. Therefore, through the second validity period information, the slave device can quickly identify and discard expired update information, avoiding waste of resources.

[0119] It should be noted that the configuration request frame of the present application also includes second reporting information, wherein the second reporting information includes at least one of the following: second surrounding AP information, used to indicate the surrounding APs detected by the STA; second RSSI, used to indicate the RSSI of the APs surrounding the STA; second EDCA parameters, used to indicate the current EDCA parameters of the STA; second RTA service mark, used to indicate that the STA has RTA service; third validity period information, used to indicate the validity period of the second reporting information; wherein the STA is an STA associated with the slave device, and the slave device obtains the second reporting information through the second configuration trigger frame sent by the STA.

[0120] It should be noted that the STA in the embodiment of the present application sends the second reporting information to the slave device, so that the slave device sends the first reporting information and the second reporting information to the master device, and then the slave device can obtain the first EDCA parameter configuration frame sent by the master device according to the first reporting information and the second reporting information. Therefore, the slave device can update its own EDCA parameters according to the first EDCA parameter configuration frame, thereby avoiding the situation where multiple BSSs appear near the same location and the BSSs may overlap to generate OBSS.

[0121] It can be understood that the second reporting information sent by the STA of the present application to the slave device includes at least one of the following: second surrounding AP information, second RSSI, second EDCA parameters, second RTA service mark, and third validity period information. The embodiment of the present application does not specifically limit the content of the second reporting information.

[0122] Please refer to Figure 6, which is a flowchart of a method for configuring enhanced distributed channel access (EDCA) parameters according to an embodiment of the present application. The method may be performed by an STA in the implementation environment shown in Figure 3. As shown in Figure 6, the method may include, but is not limited to, the following steps S310 to S320. Each step is described in turn below:

[0123] Step S310: Send a second configuration trigger frame to the slave device, so that the slave device sends a configuration request frame to the master device.

[0124] Step S320: Receive a first EDCA parameter configuration frame sent by the master device according to the configuration request frame, wherein the first EDCA parameter configuration frame includes EDCA update information corresponding to the slave device, and the EDCA update information is used for the corresponding slave device to update its own EDCA parameters.

[0125] It should be noted that, first, the STA in the embodiment of the present application sends a second configuration trigger frame to the slave device, causing the slave device to send a configuration request frame to the master device. Next, the STA in the embodiment of the present application receives a first EDCA parameter configuration frame sent by the master device in response to the configuration request frame. The first EDCA parameter configuration frame includes EDCA update information corresponding to the slave device, which is used by the corresponding slave device to update its own EDCA parameters. Therefore, the slave device can update its own EDCA parameters via the first EDCA parameter configuration frame, thereby avoiding the situation where multiple BSSs overlap and form OBSSs when multiple BSSs are located near the same location.

[0126] It should be noted that the second configuration trigger frame of the embodiment of the present application comprises at least one of the following: second peripheral AP information, used to indicate the peripheral AP detected by the STA; second RSSI, used to indicate the RSSI of the peripheral AP of the STA; second EDCA parameter, used to indicate the current EDCA parameter of the STA; second RTA service mark, used to indicate the existence of RTA service of the STA; and third validity period information, used to indicate the validity period of the second reporting information.

[0127] It should be noted that the STA of the embodiment of the present application can make the slave device send a configuration request frame to the master device by sending the second configuration trigger frame to the slave device, so as to obtain the first EDCA parameter configuration frame sent by the master device according to the configuration request frame, and then make the slave device update its own EDCA parameter according to the first EDCA parameter configuration frame.

[0128] It can be understood that the second configuration trigger frame sent by the STA of the embodiment of the present application to the slave device comprises at least one of the following: second peripheral AP information, second RSSI, second EDCA parameter, second RTA service mark, and third validity period information, and the embodiment of the present application does not make specific limitation on the content of the second configuration trigger frame.

[0129] In one possible embodiment, after the step of sending the second configuration trigger frame to the slave device in the step S310, the EDCA parameter configuration method further comprises a step S320 of:

[0130] In the step S320, a second EDCA parameter configuration frame is received from the slave device, and the second EDCA parameter configuration frame comprises EDCA update information, which is used for the STA to update its own EDCA parameter.

[0131] It should be noted that the STA of the embodiment of the present application can update its own EDCA parameter according to the EDCA update information in the second EDCA parameter configuration frame sent by the slave device, so as to avoid the OBSS situation that the BSSs may overlap when multiple BSSs exist in the same location.

[0132] It should be noted that each EDCA update parameter needs to wait for a random backoff time before transmission, and a random process experienced by each node is shown in FIG. 7.

[0133] It should be noted that the only single-step non-zero transition probability of the Markov process is as follows:

[0134] Assuming that s(t) and b(t) are both time-stationary random processes, and the above Markov process can converge, the probability of the node being in a specific state after convergence can be expressed as b i,k = limt→∞ P(s(t) = i, b(t) = k).

[0135] The boundary state satisfies the following equation: b i,0 = p i b 0,0 (0 < i < m)

[0136] The general state satisfies:

[0137] Using We can get:

[0138] Using the probability of being in a finite state is 1, We can get:

[0139] According to the EDCA mechanism, the countdown of the contention window counter to 0 can be sent, so there is According to b i,0 = p i b 0,0 (0 < i < m) and We can get:

[0140] For a system consisting of n nodes, the probability of each node sending data is independent, so for each sending node collision probability p and sending probability τ there is also the following relationship: p = 1 - (1 - τ) n-1

[0141] Therefore, together with And p = 1 - (1 - τ) n-1 Solving this nonlinear equation set can get the collision probability of a node sending a frame under the condition of known number of competing nodes n, CWmin, and CWmax.

[0142] When m = 0, Can be simplified as:

[0143] The probability of a node sending can be represented as:

[0144] As shown in FIG. 8 and FIG. 9, as CWmin increases, the channel access opportunity decreases, and thus the number of transmitted packets decreases. Meanwhile, the collision probability decreases, and thus the success rate of transmission increases. The actual number of successfully transmitted packets increases first and then decreases with CWmin, because the increase of CWmin effectively reduces the collision probability at first, and the increase of CWmin leads to fewer transmission opportunities later. If the system throughput is expected to increase, CWmin should be adjusted appropriately at this time, as shown in FIG. 8, the system throughput is the largest when CWmin = 5 in the embodiment of the application. If the system delay jitter is expected to be lower, the success rate of transmission needs to be ensured and the collision needs to be reduced, and at this time, CWmin should be adjusted as large as possible.

[0145] It can be understood that CWmin should be adjusted according to the number of APs under the same FTTR, and the adjustment direction is that the more APs, the larger CWmin.

Therefore, the slave device can update the EDCA parameter of the slave device according to the EDCA update information corresponding to the slave device included in the first EDCA parameter configuration frame, so as to avoid the case that multiple BSSs may overlap to generate OBSS when multiple BSSs appear near the same location.

Finally, the master device sends a first EDCA parameter configuration frame to each target slave device, wherein the first EDCA parameter configuration frame includes the EDCA update information corresponding to the target slave device, and the EDCA update information is used to update the EDCA parameter of the corresponding slave device. Therefore, each target slave device updates its own EDCA parameter according to the EDCA update information corresponding to the target slave device included in the first EDCA parameter configuration frame, thereby avoiding the OBSS situation that a plurality of BSSs may overlap when a plurality of BSSs exist in the same location.

[0154] It should be noted that the configuration request frame includes first report information, and the first report information includes at least one of the following: first surrounding AP information, which is used to indicate a surrounding AP detected by the slave device; a first received signal strength indication (RSSI), which is used to indicate an RSSI corresponding to a surrounding AP of the slave device; a first EDCA parameter, which is used to indicate a current EDCA parameter of the slave device; a first real-time application (RTA) traffic indication, which is used to indicate that there is RTA traffic in the slave device; and first validity period information, which is used to indicate a validity period of the first report information.
