[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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 full optical network for the home / small micro enterprise. 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 area required by the user 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 of the wireless 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 overlapping of BSSs to form an OBSS is the main problem faced by the industry at present.

[0038] Please refer to Figure 1 , Figure 1 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 the air interface competition of the area served by BSS1 and the area served by BSS2. In this case, the opportunity for STA1 to obtain a transmission time window will be greatly reduced, resulting in a decrease in throughput, an increase in latency, and a significant deterioration in user experience, especially for STA1 that 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 at this time will be even worse.

[0039] Please refer to Figure 2 , Figure 2is another FTTR structure diagram provided by the related art. The current protocol lacks an effective EDCA parameter synchronization mechanism, thereby causing the communication effect of high-priority services, especially delay-sensitive RTA, to be difficult to guarantee. Even if the BSS1 and BSS2 nodes know the existence of each other in the FTTR networking scene, they cannot know that the other party has VIP (Very Important Person) services that need high priority, especially when the VIP services are located on STA1 and STA2, and the OBSS cannot even know the existence thereof.

[0040] Based on this, the embodiment of the present application provides an enhanced distributed channel access (EDCA) parameter configuration method, which aims to dynamically configure the EDCA parameter, thereby avoiding the case that the BSSs may overlap to generate the OBSS when multiple BSSs appear near the same location.

[0041] 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 device. 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 functions of selecting to receive the data sent by the OLT; responding to the management command issued by the OLT and making corresponding adjustments; buffering the Ethernet data of the user and sending it to the uplink in the transmission window allocated by the OLT; and other user management functions.

[0055] It should be noted that the slave device of the embodiment of the present application can obtain the first EDCA parameter configuration frame sent by the master device according to the first report information by sending the first report information to the master device, thereby updating the EDCA parameter of itself according to the first EDCA parameter configuration frame, and further avoiding the OBSS situation that the BSSs may overlap when multiple BSSs appear near the same location.

[0061] It should be noted that the slave device of the present application can send the configuration request frame to the master device through the received first 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.

[0062] Specifically, in a possible embodiment, before the slave device sends the configuration request frame to the master device, the enhanced distributed channel access (EDCA) parameter configuration method further includes step S140:

[0065] Exemplarily, in an embodiment, first, a second configuration trigger frame sent by a station STA is received from the device, the second configuration trigger frame is used to indicate that the slave device sends a configuration request frame to the master device; then, the configuration request frame is sent to the master device; and then, a first EDCA parameter configuration frame sent by the master device according to the configuration request frame is received, wherein the first EDCA parameter configuration frame comprises EDCA update information corresponding to the slave device, and the EDCA update information is used to update the EDCA parameter of the corresponding slave device. 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.

[0066] It should be noted that the slave device of the present application can send the 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 itself according to the first EDCA parameter configuration parameter.

[0068] It should be noted that the slave device of the embodiment of the present application sends the configuration request frame to the master device through the received second report information sent by the station STA, so as to obtain the first EDCA parameter configuration frame sent by the master device according to the configuration request frame, and then update the EDCA parameter of itself according to the first EDCA parameter configuration frame, thereby avoiding the OBSS situation that the BSSs may overlap when multiple BSSs appear near the same location.

[0071] Exemplarily, in an embodiment, first, the second report information sent by the station STA from the device is received, and the second report information is used to indicate that the configuration request frame is sent from the device to the master device; then, the first report information and the second report information are sent to the master device; and then, the first EDCA parameter configuration frame sent by the master device according to the first report information and the second report information is received, wherein the first EDCA parameter configuration frame includes the EDCA update information corresponding to the slave device, and the EDCA update information is used to update the EDCA parameter of the corresponding slave device. 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.

[0074] Specifically, in one possible embodiment, the enhanced distributed channel access EDCA parameter configuration method further includes the following step S150:

[0075] In step S150, the second EDCA parameter configuration frame is sent to the STA, and the second EDCA parameter configuration frame includes the EDCA update information, so that the STA updates the EDCA parameter of itself according to the EDCA update information.

[0076] It should be noted that the STA can update the EDCA parameter of itself according to the EDCA update information included in the second EDCA parameter configuration frame, so as to avoid the OBSS situation that the BSSs may overlap when multiple BSSs appear near the same location.

[0077] 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.

[0078] 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, the slave device can update its own EDCA parameters; in addition, if there is no second validity period information, the slave device can continuously attempt to receive and process expired EDCA update information, which not only occupies the processing resources of the slave device, but also can cause network congestion, therefore, through the second validity period information, the slave device can quickly identify and discard the expired update information, avoiding the waste of resources.

Therefore, each target slave device updates its own EDCA parameters according to the EDCA update information corresponding to the target slave device included in the first EDCA parameter configuration frame, thereby avoiding the situation that when multiple BSSs appear in the same location, the BSSs can overlap to generate OBSS.

[0094] For example, in one embodiment, first, the master device sends a first configuration trigger frame to the slave device, where the first configuration trigger frame is 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, the master device determines, according to the first surrounding AP information and the first RSSI, other slave devices that have an OBSS with the slave device, determines the slave device and the other slave devices that have the OBSS with the slave device as the target slave devices, and determines the EDCA update information corresponding to the target slave devices according to the configuration request frame; and finally, the master device sends a first EDCA parameter configuration frame to each target slave device, where 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 the EDCA parameter of the slave device. Therefore, each target slave device updates the EDCA parameter of the target slave device according to the EDCA update information included in the first EDCA parameter configuration frame, thereby avoiding the situation that the BSSs may overlap to generate an OBSS when multiple BSSs exist in the same location.

[0095] Specifically, in one possible embodiment, regarding the determination of the at least one target slave device according to the configuration request frame in the step S220, the EDCA parameter configuration method further includes a step S260 of:

[0096] Step S260, when it is determined according to the first RTA service mark that 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.

[0097] 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, 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.

[0098] Exemplarily, in an embodiment, first, the master device sends a first configuration trigger frame to the slave device, the first configuration trigger frame is 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 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, the slave device and the other slave devices existing 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 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 case that when multiple BSSs exist in the same location, the BSSs may overlap to generate OBSS.

[0099] It should be noted that the EDCA update information of the present application includes at least one of the following: minimum contention window CWmin update information, maximum contention window CWmax update information, transmission opportunity TXOP update information, arbitration inter-frame space number AIFSN update information, and the content of the EDCA update information is not limited in the embodiment of the present application.

[0100] Specifically, in a possible embodiment, regarding the determination process of the EDCA update information corresponding to the target slave device in the above step S220, the enhanced distributed channel access EDCA parameter configuration method further includes steps S270-S280:

[0101] Step S270, determining the number of slave devices existing RTA service according to the received first RTA service mark;

[0102] Step S280, determining the EDCA update information according to the number of the slave devices.

[0103] It should be noted that the master device in the embodiment of the application can determine the number of the slave devices with the RTA service according to the received first RTA service mark, and determine the EDCA update information according to the number of the slave devices.

[0104] It can be understood that the master device in the embodiment of the application can determine the number of the slave devices with the RTA service according to the first RTA service mark, and determine the EDCA update information according to the number of the slave devices, so that the target slave device can update its own EDCA parameters according to the EDCA update information.

[0105] Specifically, in one possible embodiment, regarding the above-mentioned step S280, the enhanced distributed channel access EDCA parameter configuration method further includes steps S281-S284:

[0106] Step S281, determining a first CWmin value according to the number of the slave devices and a preset first parameter;

[0107] Step S282, determining a second CWmin value according to the first CWmin value and a preset second parameter;

[0108] Step S283, taking the first CWmin value as the CWmin update information of the target slave device with the RTA service;

[0109] Step S284, taking the second CWmin value as the CWmin update information of the target slave device without the RTA service.

[0110] It should be noted that first, the master device in the embodiment of the application can determine the first CWmin value according to the number of the slave devices and the preset first parameter; second, the master device in the embodiment of the application can determine the second CWmin value according to the first CWmin value and the preset second parameter; third, the master device in the embodiment of the application can take the first CWmin value as the CWmin update information of the target slave device with the RTA service; and finally, the master device in the embodiment of the application can take the second CWmin value as the CWmin update information of the target slave device without the RTA service.

[0111] It can be understood that the CWmin update information of the target slave device with the RTA service and the target slave device without the RTA service is different in the embodiment of the application, the CWmin update information of the target slave device with the RTA service is the first CWmin value, and the CWmin update information of the target slave device without the RTA service is the second CWmin value.

[0112] Exemplarily, 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 mark, when the slave device has RTA service, determine the first CWmin value according to the number of slave devices and the preset first parameter, and update the CWmin of the target slave device as the first CWmin value; when the slave device has no RTA service, determine the second CWmin value according to the first CWmin value and the preset second parameter, and update the CWmin of the target slave device as the second CWmin value.

[0113] 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 CW min,non-RTA = min(2*CW min,RTA , d), wherein CW min,RTA is the first CWmin value, N RTA is the number of slave devices, a and b are the first parameter, and d is the second parameter.

[0114] It can be understood that the first parameter and the second parameter described above are preset fixed values, which can be set according to actual needs, and the embodiment of the present application does not specifically limit the specific values of the first parameter and the second parameter.

[0115] Specifically, in one possible embodiment, regarding the step S280 described above, the EDCA parameter configuration method further includes steps S285-S288:

[0116] Step S285, determining the first AIFSN value according to the number of slave devices and the preset third parameter;

[0117] Step S286, determining the second AIFSN value according to the number of slave devices and the preset fourth parameter, wherein the fourth parameter is different from the third parameter;

[0118] Step S287, updating the AIFSN of the target slave device having RTA service as the first AIFSN value;

[0119] Step S288, updating the AIFSN of the target slave device having no RTA service as the second AIFSN value.

[0120] It should be noted that, first, the master device of the embodiment of the present application can determine the first AIFSN value according to the number of slave devices and the preset third parameter; second, the master device of the embodiment of the present application can determine the second AIFSN value according to the number of slave devices and the preset fourth parameter, wherein the fourth parameter is different from the third parameter; third, the master device of the embodiment of the present application updates the AIFSN update information of the target slave device with the first AIFSN value as the target slave device with RTA service; and finally, the master device of the embodiment of the present application updates the AIFSN update information of the target slave device with the second AIFSN value as the target slave device without RTA service.

[0121] It can be understood that the AIFSN update information of the target slave device with RTA service is different from the AIFSN update information of the target slave device without RTA service in the embodiment of the present application, 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.

[0122] 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 mark, determine the first AIFSN value according to the number of slave devices and the preset third parameter when the slave device has RTA service, and update the AIFSN update information of the target slave device with the first AIFSN value; and determine the second AIFSN value according to the number of slave devices and the preset fourth parameter when the slave device does not have RTA service, and update the AIFSN update information of the target slave device with the second AIFSN value.

[0123] It can be understood that the third parameter and the fourth parameter are preset fixed values, which can be set according to actual needs, wherein the fourth parameter is different from the third parameter, and the specific values of the third parameter and the fourth parameter are not limited in the embodiment of the present application.

[0124] 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.

[0125] 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, 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, through the second validity period information, the slave device can quickly identify and discard the expired update information, avoiding the waste of resources.

[0126] It should be noted that the configuration request frame of the present application further comprises second report information, wherein the second report information comprises at least one of the following: second surrounding AP information, used to indicate the surrounding AP detected by the STA; second RSSI, used to indicate the RSSI of the surrounding 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; third validity period information, used to indicate the validity period of the second report information; wherein the STA is a STA associated with a slave device, and the slave device obtains the second report information through the second configuration trigger frame sent by the STA.

[0127] It should be noted that the STA of the embodiment of the present application sends the second report information to the slave device, so that the slave device sends the first report information and the second report 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 report information and the second report information, so that the slave device can update its own EDCA parameter according to the first EDCA parameter configuration frame, thereby avoiding the OBSS situation that multiple BSSs may overlap when multiple BSSs exist in the same location.

[0128] It can be understood that the second report information sent by the STA of the present application to the slave device comprises at least one of the following: second surrounding AP information, second RSSI, second EDCA parameter, second RTA service mark, and third validity period information, and the content of the second report information is not limited in the embodiment of the present application.

[0129] Please refer to Figure 6 , Figure 6 is a flowchart of an enhanced distributed channel access (EDCA) parameter configuration method provided by the embodiment of the present application. The execution subject of the method can be a STA in the implementation environment shown in Figure 3 . As described above, the method can include but is not limited to the following steps S310-S320, which will be introduced one by one as follows: Figure 6

[0130] Step S310, sending a second configuration trigger frame to a slave device, so as to make the slave device send a configuration request frame to a master device;

[0131] Step S320, receiving a first EDCA parameter configuration frame sent by the master device according to the configuration request frame, wherein the first EDCA parameter configuration frame comprises EDCA update information corresponding to the slave device, and the EDCA update information is used to update the EDCA parameter of the corresponding slave device.

[0132] ​It should be noted that, first, the STA of the embodiment of the present application sends a second configuration trigger frame to the slave device, so that the slave device sends a configuration request frame to the master device; then, the STA of the embodiment of the present application receives a first EDCA parameter configuration frame sent by the master device according to the configuration request frame, wherein the first EDCA parameter configuration frame comprises EDCA update information corresponding to the slave device, and the EDCA update information is used for the corresponding slave device to update the EDCA parameter of itself. Therefore, the slave device can update the EDCA parameter of itself through 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.

[0133] 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 surrounding AP information, used to indicate the surrounding AP detected by the STA; second RSSI, used to indicate the RSSI of the surrounding 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 report information.

[0134] It should be noted that the STA of the embodiment of the present application can make the slave device send the 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 further make the slave device update the EDCA parameter of itself according to the first EDCA parameter configuration frame.

[0135] 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 surrounding 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.

[0136] Specifically, 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 the step S320 of:

[0137] 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, and the EDCA update information is used for the STA to update the EDCA parameter of itself.

[0138] It should be noted that the STA of the embodiment of the present application can update the EDCA parameter of itself 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 appear near the same location.

[0139] It should be noted that each EDCA update parameter needs to wait for a random backoff time before transmission, such as Figure 7 The random process experienced by each node is shown.

[0140] It should be noted that the only single-step non-zero transition probability of the Markov process is as follows:

[0141]

[0142] Assuming that s(t) and b(t) are 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 = lim t→∞ P(s(t) = i, b(t) = k).

[0143] The boundary state satisfies the following formula:

[0144] b i，0 = p i b 0，o (0 < i < m)

[0145]

[0146] Generally, the state satisfies:

[0147]

[0148] Using can be obtained:

[0149]

[0150] Using the fact that the probability of being in a finite state is 1, can be obtained:

[0151]

[0152] According to the EDCA mechanism, the countdown of the contention window counter to 0 can be transmitted, so According to b i，0 = p i b 0，0 (0 < i < m) and can be obtained:

[0153]

[0154] For a system consisting of n nodes, the probability of each node transmitting data is independent, so for each transmitting node collision probability p and transmission probability τ there is also the following relationship:

[0155] p = 1 - (1 - τ) n-1

[0156] Therefore, the simultaneous equations and p = 1 - (1 - τ) n-1 are solved to obtain the collision probability of a node sending a frame under the conditions of a known number of competing nodes n, CWmin, and CWmax.

[0157]

[0158] When m = 0, can be simplified as:

[0159]

[0160] The probability of a node sending a frame can be expressed as:

[0161]

[0162] As shown in Figure 8 and Figure 9 , as CWmin increases, the channel access opportunity decreases, and thus the number of sent packets decreases. At the same time, the collision probability decreases, and thus the success rate of sending increases. The actual number of successfully sent packets increases first and then decreases with CWmin, because the increase in CWmin initially effectively reduces the collision probability, and then the increase in CWmin leads to fewer sending opportunities. If the system throughput is expected to increase, CWmin should be adjusted at this time, as shown in Figure 8 , the throughput of the system is the largest when CWmin = 5. If the system delay jitter is expected to be low, the success rate of sending needs to be ensured and the collision needs to be reduced, and at this time CWmin should be adjusted as large as possible.

[0163] 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.

[0164] Example 1:

[0165] As shown in Figure 10As shown, the enhanced distributed channel access, EDCA, parameter configuration method provided by the embodiments of the present application is executed by the slave device.

Finally, the master device sends a first EDCA parameter configuration frame 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 target 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, thereby avoiding the situation that when multiple BSSs appear in the same location, the BSSs may overlap to generate an OBSS.
