Description

Technical Field

[0001] Embodiments of the present application relate to the field of communications, and in particular, to a communication method, a communication device, and a communication network. Background Art

[0002] With the increasing development of communication technologies, wireless transmission technologies have been applied in all walks of life and become one of the mainstream transmission technologies. Among them, Wi-Fi (wireless fidelity) technology has gradually become one of the most widely used wireless transmission technologies. In scenarios adopting Wi-Fi technology, there are usually multiple corresponding devices for implementing wireless communication.

[0003] For example, in scenarios such as fiber to the home (FTTH) and fiber to the room (FTTR), there are usually multiple devices such as an optical line terminal (OLT) and an optical network terminal (commonly known as an "optical modem", ONT). Further, in the above scenarios adopting Wi-Fi technology, there are also a router and other possible wireless communication devices (also referred to as access point (AP) devices or access devices). Among them, for operators, the number of users may reach hundreds of millions, and the number of corresponding AP devices (such as ONTs) is also very large. There will be very serious interference problems among a large number of AP devices, resulting in a very poor user experience. Therefore, there is an urgent need for a solution to improve the interference problem of AP devices.

[0004] Based on the above problems, usually, operation and maintenance personnel input corresponding information, and configure a certain AP device through a network management platform (or other devices such as a router), that is, manually plan the configuration of a single AP device to improve the interference problem faced by the AP device. However, with this solution, centralized configuration of multiple AP devices cannot be achieved. If the number of AP devices is large, operation and maintenance personnel will face a huge workload. In addition, since it is impossible for humans to timely determine the interference situation between AP devices and it is difficult to specifically calculate the optimal configuration parameters of AP devices, real-time configuration of AP devices cannot be achieved relying on manual planning. Summary of the Invention

[0005] The present application provides a communication method, a communication device, and a communication network. Through this communication method, configuration information can be generated in response to interference information determined by an AP device, and centralized configuration of the AP device can be achieved through the generated configuration information.

[0006] In a first aspect, a communication method is provided. The communication method includes: a network device receiving interference information sent by a first access AP device, where the interference information is used to indicate the interference of a wireless signal sent by a second access AP device on the first access AP device; generating configuration information in response to the interference information; where the configuration information is used to indicate parameter configuration for the first access AP device; and sending the configuration information to the first access AP device. Optionally, the parameters for configuring the first access AP device include one or more of the following: power, channel adjustment, bandwidth, air interface, traffic control, channel state information (CSI), scheduling weight, and uplink and downlink modulation and coding scheme (MCS).

[0007] Then, the network device in the above solution can receive and respond to the interference information sent by the AP device, generate configuration information and send it to the AP device. Among them, the network device can be an upper-layer network device in a communication network. For example, the network device located on the OLT side can receive the interference information determined by the AP device through the optical network between the ONT and the OLT, and then generate configuration information in response to the interference information, and configure the AP device by sending the configuration information to the AP device, so that the interference received by the AP device is reduced. Usually, in an actual application scenario, a communication network often includes multiple AP devices, and there is interference between the devices. Therefore, through the above solution, based on the multiple interference information sent by multiple AP devices, configuration information including the configuration parameters of multiple AP devices can be generated, and then the parameter configuration of multiple AP devices can be centrally implemented through the configuration information (that is, multiple AP devices are configured by one network device). It is not difficult to understand that the configuration information can indicate the configuration of one or more parameters of the AP device, and this application does not limit the number and type of parameters for parameter configuration. Further, multiple AP devices perform parameter configuration based on the configuration information, which can reduce interference and ensure their communication effects. Then, the above solution can implement the configuration of the AP device through the generated configuration information, thereby reducing the interference of the AP device and improving the user experience. In addition, multiple AP devices can be centrally configured in real time through the above solution, with higher efficiency.

[0008] In a possible implementation manner, the interference information includes: the device identifier of the second access AP device, the signal strength of the wireless signal received by the first access AP device, and the service information of the first access AP device; where the service information includes one or more of the following: air interface, delay, packet loss rate, application type, number of applications, application name, number of users, and bandwidth.

[0009] Then, through the above solution, the network device can generate configuration information in response to interference information including the signal strength of the wireless signal received by the AP device and the device identifiers of other AP devices except the AP device; and / or, the network device can generate configuration information in response to interference information including the service information of the AP device. Optionally, the service information of the AP device includes one or more of air interface, latency, packet loss rate, application type, number of applications, application name, number of users, and bandwidth. Of course, in some other instances, the service information of the AP device may also include other parameters, which are not limited in this application. Then, through the above solution, the network device can generate corresponding configuration information in response to interference information including different parameters, so the compatibility of the solution is higher. Further, by configuring the parameters of the AP device with this configuration information, the accuracy is also higher.

[0010] In a possible implementation, before generating configuration information in response to interference information, it includes: determining that the interference information meets one or more of the following conditions: the service information of the first access AP device meets the first target condition, the device identifier of the second access AP device meets the second target condition, and the signal strength of the wireless signal received by the first access AP device meets the third target condition.

[0011] Then, in the above solution, the network device first determines whether the interference information of the AP device (including the service information of the AP device, the signal strength of the received wireless signal, and the device identifiers of other AP devices except the AP device) meets one or more corresponding target conditions, and then generates configuration information in response to the interference information. Specifically, taking the first target condition as exceeding the latency threshold of the AP device as an example, when the network device determines that the service information (i.e., latency) of the AP device exceeds the latency threshold of the AP device, it will generate configuration information in response to the interference information. In this way, the network device can first determine (whether it changes) the interference information based on the corresponding target conditions, and then generate the corresponding configuration information. For example, when the network device determines that the service information of the AP device has changed (i.e., the first target condition is not equal to the service information of the AP device at the previous moment), it generates new configuration information. In a possible implementation, if the interference information of the AP device is the same at different times, the network device determines that the interference information does not meet the corresponding conditions and does not need to regenerate the configuration information in response to the interference information. Then, through the above solution, the network device can selectively generate configuration information by determining the received interference information, thereby effectively improving efficiency and reducing energy consumption.

[0012] In a possible implementation, generating configuration information in response to interference information includes: generating large network data according to the interference information, where the large network data includes interference information reported by a second access AP device; and generating configuration information based on the large network data, where the configuration information is used to indicate parameter configuration for a first access AP device.

[0013] Then, the network device in the above solution can generate large network data based on the received interference information, and then generate configuration information for indicating parameter configuration of the AP device based on the generated large network data. Among them, the large network data includes interference information reported by the second access AP device. Of course, the large network data can also include interference information reported by other AP devices. Then, the network device can obtain the interference of other AP devices (such as the second access AP device) on one of the AP devices (such as the first access AP device) according to the interference information sent by multiple AP devices (such as the first access AP device and the second access AP device). Then, the above solution can generate large network data including interference information of multiple AP devices according to the interference information, and then generate configuration information based on the interference relationship between the AP devices, so as to realize parameter configuration for any AP device, and the accuracy is higher.

[0014] In a possible implementation, generating configuration information based on the large network data includes: generating configuration information according to interference conditions based on the large network data; the interference conditions include one or more of the following: the data of the first access AP device affected by interference satisfies a first condition, the data of the designated user of the first access AP device affected by interference satisfies a second condition, and the data of the designated service of the first access AP device affected by interference satisfies a third condition.

[0015] Then, in the above solution, based on the large network data, configuration information can be generated according to one or more interference conditions. Among them, the interference conditions may include any one of the data of the AP device being interfered with satisfying the first condition, the data of the specified user of the AP device being interfered with satisfying the second condition, and the data of the specified service of the AP device being interfered with satisfying the third condition, or may include multiple items. Exemplarily, the first condition may be not exceeding the minimum threshold of the data of the AP device being interfered with, that is, the data of the AP device being interfered with does not exceed its minimum threshold. Among them, the minimum threshold may be the minimum value of the number of AP devices being interfered with by the AP device. For another example, the second condition may also be not exceeding the minimum threshold of the data of the specified user being interfered with, that is, the data of the specified user of the AP device being interfered with does not exceed its minimum threshold, and this minimum threshold may be the minimum value of the interference parameter indicating the degree of interference of the specified user of the AP device being interfered with. Among them, the specified user may be a very important person (VIP) user of the AP device. Optionally, the third condition includes not exceeding the minimum threshold of the data of the specified service of the AP device being interfered with, that is, the data of the specified service of the AP device being interfered with does not exceed its minimum threshold. Among them, the minimum threshold may be the minimum value of the wireless signal strength indicating the interference of the specified service of the AP device. Among them, the specified service may be the corresponding service that the AP device needs to ensure the network usage experience. Taking the live broadcast scenario as an example, it is necessary to ensure that the data of the live broadcast service of the AP device being interfered with is low to ensure the network usage experience of the live broadcast service. Of course, the first condition, the second condition, and the third condition may also include other possible corresponding parameters or conditions, and the present application does not limit this. In this way, in the process of the network device generating configuration information according to the interference conditions, corresponding configuration information can be generated correspondingly according to one or more interference conditions. In a possible implementation manner, the above solution can be implemented through a corresponding algorithm. For example, an artificial intelligence (AI) graph segmentation algorithm. Specifically, the network device can generate corresponding configuration information correspondingly through the AI graph segmentation algorithm according to one or more interference conditions. It is not difficult to understand that the present application does not limit the position, name, etc. of the AP device (i.e., the first access AP device). Then, through the above solution, the network device can adaptively generate corresponding configuration information according to the interference conditions, thereby improving the user's network usage experience and having higher compatibility.

[0016] In a possible implementation manner, the network device receives interference information sent by the first AP device, including: the network device periodically receives the interference information sent by the first access AP device at a predetermined period.

[0017] Then, in the above solution, the network device can periodically receive the interference information sent by the AP device, and then generate configuration information. Usually, the interference information of the same AP device at different times is different. Specifically, by receiving the interference information periodically sent by the AP device, the network device can generate corresponding configuration information based on the interference information at different times, and then can perform parameter configuration on the AP device in real time through the configuration information. Then, through the above solution, the network device can realize real-time configuration of the AP device by periodically receiving interference information.

[0018] In a possible implementation manner, the above communication method further includes: receiving device information sent by a first access AP device, where the device information includes one or more of the following: the device identifier of the first access AP device, the location of the first access AP device; mapping the device information to the large network data to generate a large network data map.

[0019] Then, in the above solution, the network device can receive the device information sent by the AP device, obtain device information such as the device identifier of the AP device and the location of the AP device, and generate a large network data map by mapping the device information to the large network data. Wherein, the device identifier includes the device serial number (sequence number, SN) of the AP device. Specifically, based on the interference information, the network device can generate large network data. By mapping the device information of the AP device to the large network data, the device identifier, location and other device information of the AP device can be corresponding to the interference information of the AP device, so as to generate a large network data map including the device information of the AP device. By generating the large network data map, the large network data can be visually presented to the user, and the user can intuitively understand the interference suffered by the AP device in the communication network. Then, the above solution makes the large network data visual by mapping the device information to the large network data, which is convenient for the user to make corresponding adjustments to the AP device in time based on the interference situation of the AP device. For example, according to the large network data map, the user can understand the device information and interference information of any AP device, and then perform parameter configuration on the AP device in real time through the generated configuration information, effectively reducing the interference suffered by the AP device and ensuring the communication quality of the AP device.

[0020] In a possible implementation manner, the network device includes any one of the following: optical line terminal OLT, network management platform, broadband controller, element management system (EMS).

[0021] Then, in the above solution, the network device may be an optical line terminal (OLT), a network management platform or an element management system (EMS) located on the OLT side, or an independent device or apparatus located on the OLT side, such as a broadband controller. In a possible implementation, the network device may also be implemented by other possible communication devices included in the FTTR scenario. For another example, the network device may also be a possible communication device or communication apparatus in the upper-layer network (relative to the AP device). Then, the above communication method can be presented by products in various forms, reducing the deployment difficulty of the communication network and having higher compatibility.

[0022] In a second aspect, a communication method is provided. The communication method includes: a first access AP device acquiring a wireless signal sent by a second access AP device; determining interference information of the first access AP device based on the wireless signal, where the interference information is used to indicate the interference of the wireless signal sent by the second access AP device on the first access AP device; sending the interference information to a network device; and receiving configuration information generated by the network device in response to the interference information, where the configuration information is used to indicate parameter configuration for the first access AP device.

[0023] Then, in the above solution, the AP device can determine interference information based on the wireless signal and send the interference information to the network device. Further, the AP device receives the configuration information generated by the network device in response to the interference information. Although, generally, the operation and maintenance personnel can adjust the configuration parameters of the AP device by inputting corresponding information (such as configuration parameters) based on the communication status of a certain AP device. For example, the operation and maintenance personnel can input the corresponding configuration parameters through the network management platform to manually plan the configuration of a single AP device, which can, to a certain extent, improve the interference problem faced by the AP device. However, a communication network usually includes multiple AP devices, and there may be interference between any two AP devices, and the interference received by any AP device at different times is often different. Therefore, relying solely on manual operation cannot timely determine the interference between different AP devices, nor can it calculate the optimal configuration parameters of any AP device, and it is impossible to achieve centralized configuration of multiple AP devices. Through the above solution, the AP device can determine other AP devices that cause interference to it based on the acquired wireless signal, thereby determining the interference information and sending the interference information to the network device. Further, according to the received configuration information, the AP device can perform parameter configuration. Optionally, the parameters for which the AP device can perform parameter configuration include one or more of the following: power, channel adjustment, bandwidth, air interface, traffic control, channel state information CSI, scheduling weight, and uplink and downlink modulation and coding scheme MCS. Of course, the AP device may also configure other types of parameters or a larger number of parameters based on the configuration information, and this application does not limit this. Then, the above solution can determine the interference information of the AP device, and then instruct the AP device to perform corresponding parameter configuration through the generated configuration information.

[0024] In a possible implementation manner, the interference information includes: the device identifier of the second access AP device and the signal strength of the wireless signal received by the first access AP device, and / or, the service information of the first access AP device; wherein, the service information includes one or more of the following: air interface, delay, packet loss rate, application type, number of applications, application name, number of users, bandwidth.

[0025] Then, in the above solution, the AP device (such as the first AP device) can determine the signal strength of the wireless signal received by the AP device (the first AP device) and the device identifier of other AP devices (such as the second AP device) that send the wireless signal, and / or the service information of the AP device (such as the first AP device), so as to determine its own interference information. Among them, the service information includes one or more of the following: air interface, latency, packet loss rate, application type, number of applications, application name, number of users, bandwidth. In a possible implementation, the device identifier of other AP devices includes a service set identifier (SSID). In this way, the AP device can determine other AP devices that cause interference to itself according to the SSID. Of course, the above solution also includes other device identifiers that can distinguish AP devices. For example, the AP device can also use the device name to determine other AP devices that cause interference to itself. In addition, the wireless signals sent by other AP devices usually interfere with the AP device, affecting the service state of the AP device, and thus affecting the service information of the AP device (such as latency, packet loss rate). Through the above solution, the AP device can determine its own service information according to the obtained wireless signal, where the service information can represent the service state of the AP device. In this way, through the service information, the AP device can determine its own interference information, and the interference information can be used to generate configuration information. Then, through the above solution, the AP device can determine the signal strength of the received wireless signal and the device identifier of other AP devices, and / or its own service information according to the wireless signal, and then determine the interference information. Further, the AP device can adaptively perform parameter configuration through the configuration information generated in response to the interference information. In this way, more optimal configuration of the AP device can be achieved, thus ensuring the communication quality of the AP device. Of course, after the parameter configuration of the AP device, or the device identifier of other AP devices that send wireless signals or the service information of the AP device may be different at different times, that is, the interference information of the AP device may change. Then, through the communication method provided in this application, configuration information can also be regenerated based on the changed interference information to ensure real-time configuration of the AP device.

[0026] In a possible implementation, before sending the interference information to the network device, it includes: determining that the interference information satisfies one or more of the following conditions: the service information of the first access AP device satisfies the first target condition, the device identifier of the second access AP device satisfies the second target condition, and the signal strength of the wireless signal received by the first access AP device satisfies the third target condition.

[0027] Then, the AP device can first determine whether the interference information (including the service information of the AP device, the signal strength of the received wireless signal, and the device identifiers of other AP devices except this AP device) meets one or more corresponding target conditions, and then selectively send the interference information to the network device. Taking the first target condition being exceeding the time delay threshold as an example, when the AP device determines that its own service information (i.e., the time delay) exceeds the time delay threshold, it will send the interference information to the network device. In a possible implementation manner, the interference information of a certain AP device at different times is the same, but the signal strength of the received wireless signal and the device identifiers of other AP devices are the same. In this way, the AP device can first determine the interference information based on the corresponding target conditions (such as confirming whether the service information changes), and then selectively send the interference information to the network device. For example, after the AP device determines that its own service information has changed (i.e., the first target condition is that the service information at the current moment is not equal to the service information at the previous moment), it sends the interference information to the network device. Then, through the above solution, the AP device can first determine the interference information and then selectively send the interference information to the network device, thereby effectively improving efficiency, reducing energy consumption, and reducing costs.

[0028] In a possible implementation manner, the first access AP device acquires the wireless signal sent by the second access AP device, including: the first access AP device periodically acquires the wireless signal sent by the second access AP device at a predetermined period.

[0029] Then, in the above solution, the AP device (such as the first access AP device) can periodically acquire the wireless signal sent by other AP devices (such as the second access AP device), and then determine the interference information based on the wireless signal. Optionally, the AP device can send the determined interference information to the network device. In a possible implementation manner, the communication status or configuration information of the AP device is different at different times. In this way, through the above solution, the AP device can acquire the wireless signal at a predetermined period, that is, at fixed time intervals, and then determine the interference information based on the wireless signal. Further, by reporting the interference information to the network device, the network device can timely determine the interference situation of this AP device at the current moment and correspondingly generate the corresponding configuration information, so as to perform parameter configuration on the AP device in real time. Then, the AP device in the above solution can periodically acquire the interference information, and then can perform parameter configuration in real time through the received corresponding configuration information.

[0030] In a possible implementation manner, the above communication method further includes: sending device information to the network device, where the device information includes one or more of the following: the device identifier of the first access AP device, the location of the first access AP device.

[0031] Then, in the above solution, the AP device can send device information including one or more of the device identifier of the AP device and the location of the AP device to the network device. In a possible implementation, the device identifier of the AP device may be the serial number SN of the AP device. Of course, the device identifier of the AP device may also be a name or other device information that can achieve similar functions. Optionally, the network device can map the device information to the backbone network data to generate a backbone network data graph. It is not difficult to understand that, based on other method examples of this application, the network device can generate backbone network data based on the interference information sent by the AP device. In this way, based on the above solution, the network device can also map the received device information to the generated backbone network data, so that device information such as the device identifier and location of the AP device can correspond to the interference information of the AP device, thereby generating a backbone network data graph including the device information of the AP device and the interference information of the AP device. Through the backbone network data graph, the backbone network data can be visually presented to the user, and the user can intuitively understand the interference received by any AP device. Then, the above solution can visualize the backbone network data by sending the device information of the AP device to the network device, and the user can clearly and intuitively understand the interference received by the AP devices in the communication network.

[0032] In a third aspect, a communication device is provided. The communication device includes a processor and an interface circuit, wherein the processor is coupled to the interface circuit; the processor is configured to execute computer programs or instructions stored in a memory and control the interface circuit to execute the communication method according to any one of the first aspects.

[0033] In a fourth aspect, a communication device is provided. The communication device includes a processor and an interface circuit, wherein the processor is coupled to the interface circuit; the processor is configured to execute computer programs or instructions stored in a memory and control the interface circuit to execute the communication method according to any one of the second aspects.

[0034] In a fifth aspect, a communication device is provided. The communication device includes: a transceiver unit: configured to receive interference information sent by a first access AP device, where the interference information is used to indicate the interference of the wireless signal sent by a second access AP device on the first access AP device; a processing unit: configured to generate configuration information in response to the interference information received by the transceiver unit, where the configuration information is used to indicate parameter configuration for the first access AP device; the transceiver unit: further configured to send the configuration information generated by the processing unit to the first access AP device.

[0035] In a sixth aspect, a communication device is provided. The communication device includes: a transceiver unit configured to obtain a wireless signal sent by a second access AP device; a processing unit configured to determine interference information based on the wireless signal obtained by the transceiver unit, where the interference information is used to indicate the interference of the wireless signal sent by the second access AP device on a first access AP device; the transceiver unit is further configured to send the interference information to a network device and receive configuration information generated by the network device in response to the interference information, where the configuration information is used to indicate parameter configuration for the first access AP device.

[0037] It should be noted that the technical effects brought by any of the design manners in the above third aspect to the seventh aspect can be referred to the technical effects brought by different design manners in the above first aspect and the second aspect, and will not be elaborated herein.

[0045] Aspects, embodiments or features of the present application will be presented in the context of a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in connection with the figures. In addition, combinations of these solutions may also be used. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings.

[0047] With the increasing development of communication technologies, wireless transmission technologies have been applied in various industries and have become one of the mainstream transmission technologies. Among them, Wi-Fi technology has gradually become one of the most widely used wireless transmission technologies.

[0048] In a fiber to the x (FTTx) scenario using Wi-Fi technology, it usually includes multiple communication devices for wireless transmission. For example, in scenarios such as FTTH and FTTR, it usually includes multiple devices such as an optical line terminal (OLT) and an optical network terminal (ONT). Exemplarily, referring to Figure 1 As shown, an embodiment of the present application provides a schematic diagram of a fiber access network. The fiber access network is also referred to as an optical access network (OAN). For ease of explanation, the Figure 1 fiber access network shown is denoted as OAN 10.

[0049] Specifically, as shown in Figure 1 , OAN 10 includes: an optical line terminal OLT ( Figure 1 101 in Figure 1 ), an optical distribution network (ODN) ( Figure 1 102 in Figure 1 ), and an optical network terminal ONT ( Figure 1 103 in Figure 1 ). Among them, the OLT is usually set at the central office end (for example, it can be a central control station). Optionally, the OAN may also include an optical network unit (ONU) set on the user side (which can also be referred to as the terminal side). Among them, the ONT or ONU is usually set at different positions on the user side and realizes similar functions. It is not difficult to understand that the ONT and ONU realize similar functions and are usually regarded as components of the ONU. Therefore, for ease of explanation,Figure 1 In the OAN 10 shown, only the ONT 103 is taken as an example on the user side, and the types and quantities of devices included in the OAN should not be limited thereby. Among them, Figure 1 two ONTs are shown, namely ONT 103-a and ONT 103-b.

[0050] Optionally, the OAN 10 further includes an optical distribution network ODN (refer to the ODN 102 in Figure 1 ) that connects the OLT and the ONT. In a possible implementation, as shown in Figure 1 , the ODN 102 includes a splitter 102-1. The splitter 102-1 includes an input end, an output end a, and an output end b. Among them, the input end of the splitter 102-1 is connected to the OLT 101 through an optical fiber, the output end a of the splitter 102-1 is connected to the ONT 103-a through an optical fiber, and the output end b of the splitter 102-1 is connected to the ONT 103-b through an optical fiber.

[0051] Optionally, the ODN may further include a multi-stage splitter, that is, multiple splitters are provided to achieve multi-stage splitting of optical signals. In other examples, the splitter may also include more or fewer output ends. For example, as shown in Figure 1 , the ODN 102 may only include a first-stage splitter (such as the splitter 102-1), or the ODN 102 may include multiple splitters with two or more stages. Specifically, the function of the ODN 102 is to transmit the downstream optical signal of the OLT 101 to any one of the ONTs 103, and to transmit the upstream optical signal of any one of the ONTs 103 to the OLT 101. The embodiments of the present application do not limit the number of splitters included in the ODN, nor do they limit the number of output ports of each splitter, etc.

[0052] Specifically, taking the downstream direction as an example: when the OAN 10 operates, the OLT 101 transmits the downstream optical signal to the ODN 102. Among them, the input end of the splitter 102-1 in the ODN 102 receives the downstream optical signal, and transmits the downstream optical signal from the output end a to the ONT 103-a and from the output end b to the ONT 103-b. The ONT 103-a and the ONT 103-b receive the downstream optical signal and process the received downstream optical signal to obtain the data therein. It is not difficult to understand that only the transmission process of the optical signal in the downstream direction in the OAN 10 shown in Figure 1 is taken as an example here, and the specific signal transmission process in the OAN should not be limited thereby.

[0053] Of course, in some other embodiments, the ONT 103 can also generate an upstream optical signal to be sent to the OLT 101. For example, when the ONT 103-a generates an upstream optical signal, the ONT 103-a will transmit the upstream optical signal to the OLT 101 through the output end a of the splitter 102-1 and the input end of the splitter 102-1 in sequence.

[0054] Then, as a fiber access network, the OAN 10 can realize the transmission of signals in the upstream and downstream directions by using optical fibers (optical transmission media) as the connection media. Refer to Figure 1 In the shown OAN 10, the OLT 101, the ODN 102, and the ONT 103 are all connected by optical fibers, and both upstream optical signals and downstream optical signals can be transmitted in these optical fibers. Of course, there may be other types of communication networks deployed between the ONT on the user side and the user, such as Ethernet. Among them, the connection media between the ONT and other types of communication networks include optical transmission media such as optical fibers, and also include other non-optical fiber connection media that may realize the corresponding functions to ensure that the ONT can be connected to other types of communication networks. The embodiments of the present application do not limit this.

[0055] It should be noted that only Figure 1 the shown fiber access network OAN 10 is taken as an example to illustrate the possible application scenarios of the wireless transmission technology. It is not difficult to understand that there are other possible application scenarios for the wireless transmission technology, and the types of scenarios applicable to the wireless transmission technology and the network architectures applied should not be limited thereby. For example, in some other examples, the OLT located at the central office can also be used to connect to a network management platform (also called network management).

[0056] Generally, in a scenario where the Wi-Fi technology is adopted, there may also be wireless communication devices such as routers (also called AP devices or access devices). For example, in combination with Figure 1 the shown OAN 10, the ONT 103 on the user side can also be implemented by an ONT integrated with the function of an AP device. Generally speaking, the number of users faced by an operator is often extremely large, and even the number of users may reach hundreds of millions. Correspondingly, the number of AP devices that the operator needs to face will also be extremely large. This will cause any AP device in the communication network to possibly face interference from different AP devices.

[0057] Based on the above, exemplarily, refer to Figure 2 the shown figure, and the embodiments of the present application provide a schematic diagram of an application scenario of the Wi-Fi technology. In combination with Figure 2As shown in the figure, this scenario includes: an unknown network, which is connected to an AP device; a network management platform, which is connected to OLT 11 and OLT 12. Among them, OLT 11 is connected to ONT, and OLT 12 is connected to the main gateway, and the main gateway is connected to slave gateway 21 and slave gateway 22. This scenario also includes: other network management platforms. Among them, the above-mentioned main gateway and slave gateways can be implemented by various possible devices or apparatuses, for example, they can be AP devices.

[0058] Optionally, referring to Figure 2 As shown in the figure, the architecture in which the network management platform is connected to ONT or the corresponding slave gateway can also be used to implement FTTR. The embodiments of the present application do not make any limitations in this regard. It is not difficult to understand that, for the sake of convenience of description, only the Figure 2 scenario shown in the figure is taken as an example here, and it should not be used to limit the architecture of the application scenario of Wi-Fi technology.

[0059] Specifically, in combination with Figure 2 the scenario shown in the figure, the AP device connected to the unknown network will interfere with other nearby AP devices (refer to the circular shaded area on the AP device). Multiple OLTs (refer to OLT 11 and OLT 12) connected to the same network management will all interfere with other nearby AP devices, and it is difficult for the network management to determine the interference between the communication devices (refer to ONT and gateway) connected to the OLT. Multiple communication devices (refer to slave gateway 21 and slave gateway 22) connected to the same OLT (such as OLT 12) will all interfere with other nearby AP devices, and it is also difficult for the network management to accurately obtain the corresponding interference situation in real time.

[0060] Based on the above, the AP device may be interfered by different devices and it is difficult to accurately determine, which will lead to a very poor user experience. Even for the interference between AP devices within the same FTTR network (refer to the network architecture in which the network management platform is connected to ONT and the slave gateway), it is difficult for the network management to obtain. For example, taking the home network scenario as an example, it is usually difficult to determine the interference generated by AP devices in neighboring households and other unknown networks. Therefore, it is difficult to reasonably plan the configuration of AP devices in the home network, resulting in frequent interference problems and seriously affecting the user experience.

[0061] Exemplarily, referring to Figure 3 as shown in the figure, the embodiments of the present application provide a schematic diagram of the distribution of interference in a communication network. Among them, in combination with Figure 3 as shown in the figure, this communication network includes nine AP devices ( Figure 3 uses a rectangular box to represent the space where the AP devices are arranged, for example, it can be different rooms in a home or a company), labeled as Room 1 -Room 9 . Specifically, in combination withFigure 3 As shown, any AP device in this communication network will be interfered by other AP devices to varying degrees. Among them, the circular shaded areas in the figure represent the wireless signal coverage areas of each AP device, labeled as Area A - Area I, and the overlapping areas of the two wireless signal coverage areas represent the interference between AP devices. Taking a room 1 as an example, the wireless signal coverage area A of its AP device overlaps with the wireless signal coverage area B of room 2 , the wireless signal coverage area F of room 6 , and the wireless signal coverage area G of room 7 . That is, the AP device in room 1 is interfered by at least three other AP devices. Of course, the AP device in room 1 will also interfere with the AP devices in other rooms.

[0062] Generally, in the actual network usage scenario, the number of AP devices included is extremely large, that is, the number of AP devices in the communication network is very huge. For any AP device in the communication network, it may be interfered by a huge number of other AP devices. Therefore, it is difficult to accurately determine the interference received by a certain AP device only by manual means. In this way, there are very serious interference problems between AP devices and they occur frequently, resulting in a poor user experience.

[0063] Based on the above problems, the usual approach is for maintenance personnel to manually plan the interference situation between devices. Specifically, maintenance personnel manually input the corresponding information, and through a network management platform (or other devices such as routers), the configuration of a certain AP device is realized, that is, the configuration of a certain AP device is manually planned to improve the interference faced by this AP device. Or, maintenance personnel can also configure a certain AP device through the network (web) page of a certain AP device (such as an AP device in an ONT, FTTR network, or router).

[0064] However, the above solutions are difficult to apply in many scenarios. For example, user families and neighbor families may use different operators for home network deployment, which will make it difficult to determine the interference received by any AP device in the user's home network. On the other hand, since it is impossible for humans to determine the interference situation between each AP device in real time, real-time configuration of AP devices cannot be achieved through manual planning. In addition, the above solutions cannot centrally configure all AP devices in the home network through a corresponding control system. Then, if this solution is adopted, it will be difficult to specifically calculate the optimal configuration parameters of any AP device, and maintenance personnel cannot centrally configure multiple AP devices, which will make maintenance personnel face a huge workload.

[0065] Then, there is an urgent need for a solution that can centrally configure AP devices in real time based on the interference received by the AP devices, thereby improving the interference problem of the AP devices and enhancing the user experience.

[0066] Based on the above problems, exemplarily, referring to Figure 4 shown, an embodiment of the present application provides a schematic diagram of a communication method. The following will be combined with Figure 4 shown to elaborate on the communication method provided by the embodiment of the present application. It should be noted that, here, the control device and the AP device are taken as examples for illustration, and the communication method provided by the embodiment of the present application should not be limited thereby. This communication method includes steps 401 - step 407, which are specifically described as follows.

[0067] It should be noted that, based on Figure 1 and Figure 2 shown architecture, the network device in the embodiment of the present application can be an OLT (such as Figure 1 OLT 101 in Figure 2 ) or a network management platform (such as Figure 1 the network management platform in

[0068] ), or a broadband controller. Of course, the network device can also be other devices or apparatuses capable of realizing its functions, and the embodiment of the present application does not limit this. For example, the network device can also be a network element management system EMS. It is not difficult to understand that the AP device in the embodiment of the present application can be an ONT (such as Figure 2 ONT 103 - a in Figure 1 ). Of course, the AP device can also be other devices or apparatuses capable of realizing its functions, and the embodiment of the present application does not limit this.

[0069] Step 401: The AP device acquires the wireless signals sent by other AP devices.

[0070] Combined with Figure 4 shown, the AP device acquires the wireless signals sent by other AP devices. Specifically, combined with Figure 2 shown, the ONT acquires the wireless signals sent by other AP devices (such as from the gateway 21).

[0071] In a possible implementation, the AP device periodically obtains wireless signals sent by other AP devices at a predetermined period. Optionally, the number of other AP devices can be one or more (greater than or equal to two), and the embodiments of the present application do not limit this.

[0072] Step 402: The AP device determines interference information.

[0073] Combined with Figure 4 As shown, the AP device determines interference information. Specifically, combined with Figure 2 As shown, the ONT determines interference information based on the obtained wireless signals.

[0074] Optionally, the interference information of the AP device includes the signal strength of the wireless signals received by the AP device, the device identifiers of other AP devices except the AP device, and / or the service information of the AP device; wherein, the service information includes one or more of the following: air interface, latency, packet loss rate, application type, number of applications, application name, number of users, bandwidth. Optionally, the device identifier of other AP devices can be the service set identifier SSID.

[0075] In a possible implementation, the AP device determining interference information includes: the AP device determines the service set identifier SSID of other AP devices that send wireless signals and the signal strength of the received wireless signals based on the obtained wireless signals; and determines interference information according to the service set identifier SSID of other AP devices and the signal strength of the wireless signals received by itself. In some other examples, the AP device determining interference information includes: the AP device detects its own service information based on the obtained wireless signals; and determines interference information according to the service information. For the convenience of description, the above two methods are only two possible implementation manners for the AP device to determine interference information, and should not limit the method embodiments of the present application. Among them, the AP device can selectively determine interference information through any one of the above methods, or can also determine interference information in parallel through multiple (two) of the above methods. For example, based on the obtained wireless signals, the AP device can determine the service set identifier SSID of other AP devices that send wireless signals, the signal strength of the received wireless signals, and detect its own service information, so as to determine the interference information.

[0076] Step 403: The AP device sends the interference information to the network device.

[0077] Combined with Figure 4 As shown, the AP device sends the interference information to the network device. Specifically, combined with Figure 2 As shown, the ONT sends the interference information to the OLT11. Optionally, the ONT passes through the optical network (refer to Figure 1The OAN 10) shown reports the determined interference information to the OLT 11.

[0078] In a possible implementation, the AP device sends device information to the network device, wherein the device information includes one or more of the following: a device identifier of the AP device and a location of the AP device. Optionally, the device identifier may be a device serial number SN or other device identifiers capable of implementing similar functions.

[0079] Step 404: The network device receives interference information.

[0080] Combination Figure 4 As shown, the network device receives interference information. Specifically, Figure 2 As shown, OLT 11 receives interference information reported by ONT.

[0081] In combination with step 401, the AP device periodically obtains the wireless signal sent by other AP devices at a predetermined period. Optionally, the network device periodically receives the interference information sent by the AP device at a predetermined period.

[0082] Step 405: The network device generates configuration information.

[0083] Combination Figure 4 As shown, the network device generates configuration information. Specifically, Figure 2 As shown, OLT 11 generates configuration information in response to the interference information sent by the ONT, wherein the configuration information is used to instruct parameter configuration of the AP device.

[0084] In a possible implementation, the network device generates configuration information in response to interference information, including: the network device generates large network data according to the interference information; and generates configuration information based on the large network data, wherein the large network data includes interference information reported by other AP devices.

[0085] Optionally, the network device generates configuration information based on the large network data and the interference condition. Correspondingly, the interference condition includes one or more of the following: the data interfered with by the AP device meets the first condition, the data interfered with by the AP device's designated user meets the second condition, and the data interfered with by the AP device's designated service meets the third condition.

[0086] Then, illustratively, the network device generates configuration information based on the big network data and the interference conditions, including the following three methods:

[0087] Method (1): The network device determines the data on which the AP device is interfered based on the large network data; determines that the data on which the AP device is interfered meets the first condition, and generates configuration information.

[0088] Method (2): The network device determines the data of the specified user of the AP device that is interfered with based on the large network data; determines that the data of the specified user of the AP device that is interfered with meets the second condition, and generates configuration information.

[0089] Method (3): The network device determines the data of the specified service of the AP device that is interfered with based on the large network data; determines that the data of the specified service of the AP device that is interfered with meets the third condition, and generates configuration information. Among them, the expected user can be an important VIP user.

[0090] Exemplarily, the first condition can be not exceeding the minimum threshold of the data of the AP device that is interfered with, that is, the data of the AP device that is interfered with does not exceed its minimum threshold. Among them, the minimum threshold can be the minimum value of the number of AP devices that are interfered with by the AP device. Also, for example, the second condition can also be not exceeding the minimum threshold of the data of the specified user of the AP device that is interfered with, that is, the data of the specified user of the AP device that is interfered with does not exceed its minimum threshold, and this minimum threshold can be the minimum value of the interference parameter indicating the degree of interference of the specified user of the AP device. Optionally, the third condition includes not exceeding the minimum threshold of the data of the specified service of the AP device that is interfered with, that is, the data of the specified service of the AP device that is interfered with does not exceed its minimum threshold. Among them, the minimum threshold can be the minimum value of the wireless signal strength indicating the interference of the specified service of the AP device. Optionally, the above first condition, second condition, and third condition can also include other possible corresponding parameters or conditions, and the present application does not limit this.

[0091] Based on the above three methods, the communication method provided by the embodiments of the present application can realize the automatic control of the interference of the AP device based on the large network data, that is, according to various targets (such as interference conditions), corresponding configuration information can be generated through the set corresponding algorithms to realize the above process. For example, the above solution can be implemented through the AI graph segmentation algorithm, that is, according to the interference conditions, the corresponding configuration information is generated correspondingly through the AI graph segmentation algorithm.

[0092] Among them, the network device can selectively generate configuration information through any one of the above methods, or can also generate configuration information in parallel through multiple (two or three) of the above methods. Of course, only several possible examples of the network device generating configuration information are provided here. In other examples, the network device can also generate configuration information through other methods, and the embodiments of the present application do not limit this.

[0093] Optionally, as described in combination with step 403, if the AP device sends device information to the network device, the network device receives the device information sent by the AP device, maps the device information to the large network data, and generates a large network data graph.

[0094] Step 406: The network device sends the generated configuration information to the AP device.

[0095] Combined with Figure 4 As shown, the network device sends the generated configuration information to the AP device. Specifically, combined with Figure 2 As shown, OLT 11 sends the generated configuration information to the ONT.

[0096] Step 407: The AP device receives the configuration information generated by the network device.

[0097] Combined with Figure 4 As shown, the AP device receives the configuration information generated by the network device. Specifically, combined with Figure 2 As shown, the ONT receives the configuration information generated by OLT 11 in response to the interference information.

[0098] In a possible implementation, the AP device receives the configuration information generated by the network device and performs parameter configuration according to the configuration information.

[0099] Then, based on steps 401 - 407, the network device can automatically generate large network data in response to the interference information determined by one or more AP devices, generate configuration information according to the large network data, and realize real-time configuration of any AP device through the configuration information. Then, the above method can enable the terminal side of the optical network (such as the AP device on the ONT side) to automatically cooperate with the central office side of the optical network (such as the network device of the OLT), and realize automatic optimization of the AP device based on the virtual large network data. In a possible implementation, the large network data may be virtual data, that is, it does not include specific interference values and other related specific numerical values.

[0100] In a possible implementation, there are usually multiple sets of FTTR devices in an enterprise park, where the FTTR device can be implemented by an AP device. Then, based on the above method, automatic debugging of multiple sets of FTTR devices can be realized (such as adjusting and testing the Wi-Fi parameters of the FTTR device), thereby effectively reducing interference and improving the service certainty of the device. Another example is that for ordinary families, based on the above method, centralized configuration of the AP device (interference) in the home network can be realized, reducing interference and improving the user experience. In addition, based on the above solution, between AP devices produced by different manufacturers (multiple AP devices) or communication networks of different operators (multiple operators), centralized control of the interoperability of the AP device can be realized, improving device compatibility.

[0101] Among them, as described in step 402, the AP device can determine interference information based on the device identifier of other AP devices and the signal strength of the received wireless signal (and / or its own service information). Generally, the interference received by the AP device is different at different times, so the interference information of the AP device may change, that is, the SSID of other AP devices, the signal strength of the received wireless signal, and its own service information may all change. Optionally, before the AP device sends the interference information to the network device, it includes: determining that the interference information meets one or more of the following conditions: the service information of the AP device meets the first target condition, the device identifier of other AP devices meets the second target condition, and the signal strength of the wireless signal received by the AP device meets the third target condition. In a possible implementation, the AP device periodically acquires wireless signals; based on the acquired wireless signals, it determines interference information. At a certain moment, it determines that the service set identifier SSID of the other AP device sending the wireless signal has changed, and sends the interference information to the network device. Of course, the AP device can also determine based on the signal strength of the received wireless signal and / or its own service information, and then send the interference information to the network device. In this way, the AP device can determine the interference information and selectively send the interference information to the network device, thereby effectively reducing power consumption.

[0102] In a possible implementation, as described in step 404, the network device periodically receives the interference information sent by the AP device. Exemplarily, as described in step 407, if the AP device configures parameters according to the configuration information, its communication state may change, so the interference information of the AP device may change. For example, it may be that the service information changes. Then, optionally, before the network device generates configuration information in response to the interference information, it includes: determining that the interference information meets one or more of the following conditions: the service information of the AP device meets the first target condition, the device identifier of other AP devices meets the second target condition, and the signal strength of the received wireless signal of the AP device meets the third target condition. For example, the first target condition is different from the interference information at the previous moment. If the network device determines that the service information of the AP device is different from the interference information at the previous moment, it will generate configuration information in response to the interference information. In this way, the network device can first determine the received interference information and then selectively generate corresponding configuration information in response to the interference information, so as to be able to dynamically perform real-time configuration on the AP device.

[0103] It should be noted that, in combination with the above step 403, the AP device can send interference information to the network device through the corresponding communication protocol. Correspondingly, the network device analyzes the received interference information through the corresponding communication protocol. In combination with the above step 406, the network device can send the generated configuration information to the AP device through the corresponding communication protocol. Correspondingly, the AP device analyzes the received configuration information through the corresponding communication protocol.

[0104] Specifically, the sending and receiving of signals (including interference information and configuration information) in the above method can be implemented through the corresponding communication protocol. In a possible implementation manner, the communication protocol can be the optical network unit management and control Interface (OMCI) protocol. However, the communication protocol is not limited to the OMCI protocol. Optionally, the functions of the communication protocol can also be implemented through other possible protocols or methods such as the message queuing telemetry transport (MQTT) protocol, the (network configuration protocol, NETCONF) / (yet another next generation, YANG) data modeling language protocol, the technical report–069 (TR069) protocol for user terminal device wide area network management, and the extensible markup language (XML) configuration file method.

[0105] Generally, the network device on the OLT side can support the control of the virtual large network (such as large network data) of the AP device through the OMCI protocol, and at the same time, can configure parameters for the AP device based on the large network data. Of course, the network device can also implement the above functions through the MQTT protocol or other corresponding protocols, and the embodiments of the present application do not limit this. Since the network device includes any one of the OLT, the network management platform, and the broadband controller network element management system EMS, the network device in the above process can also be other devices or apparatuses capable of implementing its functions, and the embodiments of the present application do not limit this. For example, the broadband controller or EMS can support the control of the virtual large network (such as large network data) of the AP device through the corresponding protocol, and at the same time, can configure Wi-Fi parameters for the AP device based on the large network data to achieve Wi-Fi optimization. In addition, in a possible implementation manner, if the interference information of the AP device changes, the network device can generate new configuration information based on the changed interference information and send the refreshed configuration information (i.e., the new configuration information) to the AP device in real time through the OMCI protocol or the MQTT protocol.

[0106] In addition, based on step 405, the network device can visually present the generated large network data to the user through the large network data graph. Exemplarily, referring to Figure 5 as shown, an embodiment of the present application provides a schematic diagram of a possible large network data graph.

[0107] Combined with Figure 5 as shown in (1) of Figure 5 , User 1 uses three sets of communication networks, namely Network 1, Network 2, and Network 3. Among them, Network 1 includes a main gateway and two slave gateways connected to the main gateway. Optionally, the AP device includes the above-mentioned main gateway and slave gateways. The number of devices and the connection relationship inside Network 2 and Network 3 are similar to those of Network 1, which will not be elaborated here. Optionally, this scenario can be a communication network architecture corresponding to an FTTR scenario. Specifically, Network 1, Network 2, and Network 3 are respectively communication networks deployed in different rooms. In this way, since the slave gateways of Network 1 and Network 2 are relatively close to each other, the interference between the two slave gateways is relatively large (refer to the dotted circle shown in (1) of Figure 5 ), resulting in a relatively large latency or even stuttering when the communication device (such as a terminal device) connected to the slave gateway of Network 1 roams across rooms (switches to connect to the slave gateway of Network 2), seriously affecting the user's network experience.

[0108] Combined with Figure 5 as shown in (2) of

[0109] , based on the embodiment of the present application, large network data can be generated. Further, by mapping the device information (such as device serial number, location) of the AP device to the generated large network data, a large network data graph can be generated. Optionally, the AP device here includes a main gateway and slave gateways. Figure 5 as shown in (3) of Figure 5 , each of the three sets of communication networks used by User 2 includes a main gateway and two slave gateways connected to the main gateway. The communication network used by User 3 includes a main gateway and two slave gateways connected to the main gateway. Among them, based on the above method embodiment of the present application, configuration information can be generated based on the large network data according to the interference conditions. Specifically, combined with the method (2) in step 405, by determining the data of the specified user (such as the VIP user in (3) of Figure 5 ) of the AP device that is interfered, configuration information can be generated to ensure the communication effect of the VIP user using the AP device. Combined with the method (3) in step 405, by determining the data of the specified service (such as the live broadcast application in (3) of Figure 5 ) of the AP device that is interfered, configuration information can be generated to ensure the communication effect of the live broadcast application using the AP device.

[0110] Exemplarily, referring to Figure 6As shown in the figure, an embodiment of the present application provides a schematic diagram of a communication device. The communication device includes: a transceiver unit 601 and a processing unit 602; the transceiver unit 601 is configured to receive interference information sent by a first access AP device, where the interference information is used to indicate the interference of a wireless signal sent by a second access AP device on the first access AP device; the processing unit 602 is configured to generate configuration information according to the interference information received by the transceiver unit 601, where the configuration information is used to indicate parameter configuration for the first access AP device; the transceiver unit 601 is further configured to send the configuration information generated by the processing unit to the first access AP device.
