Description

Communication method, communication device and communication network

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 27, 2023, with application number 202311611259.5 and application name “A communication method, communication device and communication network”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The 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

[0003] With the rapid development of communications technology, wireless transmission has been applied to various industries and has become one of the mainstream transmission technologies. Among them, Wi-Fi (wireless fidelity) technology has gradually become the most widely used wireless transmission technology. In scenarios where Wi-Fi technology is used, multiple devices are usually included to achieve wireless communication.

[0004] For example, scenarios such as fiber to the home (FTTH) and fiber to the room (FTTR) usually include multiple devices such as optical line terminals (OLTs) and optical network terminals (commonly known as "optical cats" or optical network terminals (ONTs). Furthermore, in the above-mentioned scenarios using Wi-Fi technology, routers and other possible wireless communication devices (also known as wireless access point (AP) devices or access devices) are also included. Among them, for operators, the number of users they face may be hundreds of millions, and the number of corresponding AP devices (such as ONTs) is also very large. Serious interference problems will arise between the massive AP devices, resulting in a poor user experience. Therefore, there is an urgent need for a solution that can improve the interference problem of AP devices.

[0005] To address these issues, operations and maintenance personnel typically input the relevant information and configure a specific AP through a network management platform (which can also be a router or other device). This manually plans the configuration of a single AP to mitigate interference issues faced by the AP. However, this solution cannot centrally configure multiple APs, which creates a massive workload for operations and maintenance personnel if there are a large number of APs. Furthermore, manual planning cannot promptly determine interference between APs and is difficult to calculate the optimal configuration parameters for each AP.

[0006] Summary of the Invention

[0007] The present application provides a communication method, a communication device, and a communication network. Through the 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.

[0008] 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, wherein the interference information is used to indicate 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; wherein the configuration information is used to indicate parameter configuration of the first access AP device; and sending the configuration information to the first access AP device. Optionally, the parameters configured for the first access AP device include one or more of the following: power, channel adjustment, bandwidth, air interface, flow control, channel state information (CSI), scheduling weight, and uplink and downlink modulation and coding scheme (MCS).

[0009] 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. The network device can be an upper-layer network device in the communication network. For example, the network device 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. By sending the configuration information to the AP device, the AP device is configured, so that the interference experienced by the AP device is reduced. Typically, in actual application scenarios, a communication network often includes multiple AP devices, and interference exists between the devices. Therefore, through the above solution, based on the multiple interference information sent by multiple AP devices, configuration information including configuration parameters of multiple AP devices can be generated, and parameter configuration of multiple AP devices can be centralized through the configuration information (i.e., multiple AP devices can be configured through 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 of parameters to be configured, the type of parameters, etc. Furthermore, multiple AP devices can be configured based on the configuration information, reducing interference and ensuring effective communication. The above solution uses the generated configuration information to configure AP devices, thereby reducing AP interference and improving the user experience. Furthermore, the above solution allows for centralized configuration of multiple AP devices in real time, achieving greater efficiency.

[0010] In one possible implementation, 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 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, and bandwidth.

[0011] Then, through the above scheme, 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 identification of other AP devices other than 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 the air interface, latency, packet loss rate, application type, number of applications, application name, number of users, and bandwidth. Of course, in other instances, the service information of the AP device may also include other parameters, which is not limited in this application. Then, through the above scheme, the network device can generate corresponding configuration information in response to interference information including different parameters, so the scheme has higher compatibility. Furthermore, the parameter configuration of the AP device through the configuration information is also more accurate.

[0012] In one 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.

[0013] In the above solution, the network device first determines whether the interference information of the AP device (including the AP device's service information, the signal strength of the received wireless signal, and the device identifiers of other AP devices other than 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 being exceeding the AP device's latency threshold as an example, when the network device determines that the AP device's service information (i.e., latency) exceeds the AP device's latency threshold, it generates configuration information in response to the interference information. In this way, the network device can first determine whether the interference information has changed based on the corresponding target conditions and then generate the corresponding configuration information. For example, if the network device determines that the AP device's service information has changed (i.e., the first target condition is not equal to the AP device's service information at a previous moment), it generates new configuration information. In one possible implementation, if the interference information of the AP devices at different moments is the same, the network device determines that the interference information does not meet the corresponding conditions, and there is no need to regenerate configuration information in response to the interference information. Therefore, through the above solution, the network device can selectively generate configuration information by determining received interference information, thereby effectively improving efficiency and reducing energy consumption.

[0014] In one possible implementation, generating configuration information in response to interference information includes: generating large network data based on the interference information, the large network data including interference information reported by the second access AP device; and generating configuration information based on the large network data, the configuration information being used to instruct parameter configuration of the first access AP device.

[0015] Then, the network device in the above scheme can generate large network data based on the received interference information, and then generate configuration information for instructing parameter configuration of the AP device based on the generated large network data. Among them, the large network data includes the 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) to one of the AP devices (such as the first access AP device) based on the interference information sent by multiple AP devices (such as the first access AP device and the second access AP device). Then, the above scheme can generate large network data including interference information of multiple AP devices based on the interference information, and then generate configuration information based on the interference relationship between the AP devices, so as to realize parameter configuration of any AP device with higher accuracy.

[0016] In one possible implementation, configuration information is generated based on large network data, including: generating configuration information based on interference conditions based on large network data; the interference conditions include one or more of the following: data of the first access AP device that is interfered with meets the first condition, data of the first access AP device's designated user that is interfered with meets the second condition, and data of the first access AP device's designated service that is interfered with meets the third condition.

[0017] In the above solution, based on the macro-network data, configuration information can be generated according to one or more interference conditions. The interference conditions may include any one of the following: data on the AP device receiving interference satisfies a first condition; data on the AP device's designated user receiving interference satisfies a second condition; and data on the AP device's designated service receiving interference satisfies a third condition. Multiple conditions may also be included. For example, the first condition may be that the data on the AP device receiving interference does not exceed a minimum threshold, i.e., the data on the AP device receiving interference does not exceed its minimum threshold. The minimum threshold may be the minimum number of AP devices receiving interference. For another example, the second condition may be that the data on the AP device receiving interference does not exceed a minimum threshold, i.e., the data on the AP device receiving interference does not exceed its minimum threshold. The minimum threshold may be the minimum value of an interference parameter indicating the degree of interference to the AP device's designated user. The designated user may be a very important person (VIP) user of the AP device. Optionally, the third condition may include that the data on the AP device's designated service receiving interference does not exceed a minimum threshold, i.e., the data on the AP device receiving interference does not exceed its minimum threshold. The minimum threshold may be the minimum value of the wireless signal strength indicating interference to the AP device's designated service. Among them, the designated service can be the corresponding service that the AP device needs to ensure the network experience. Taking the live broadcast scenario as an example, it is necessary to ensure that the data of the AP device's live broadcast service is less interfered with to ensure the network 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, which are not limited in this application. In this way, in the process of generating configuration information based on the interference condition, the network device can generate corresponding configuration information according to one or more interference conditions. In one possible implementation, the above scheme can be implemented by a corresponding algorithm. For example, an artificial intelligence (AI) graph segmentation algorithm. Specifically, the network device can generate corresponding configuration information according to one or more interference conditions through the AI ​​graph segmentation algorithm. It is not difficult to understand that the present application does not limit the location, name, etc. of the AP device (i.e., the first access AP device). Then, through the above scheme, the network device can adaptively generate corresponding configuration information according to the interference condition, thereby improving the user's network experience and having higher compatibility.

[0018] In a possible implementation, the network device receives the 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.

[0019] In the above solution, the network device can periodically receive interference information sent by the AP device and generate configuration information. Typically, the interference information for the same AP device varies at different times. 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. This configuration information can then be used to configure parameters for the AP device in real time. Therefore, through the above solution, the network device can achieve real-time configuration of the AP device by periodically receiving interference information.

[0020] In one possible implementation, the above-mentioned communication method also includes: receiving device information sent by the first access AP device, wherein the device information includes one or more of the following: a device identifier of the first access AP device, a location of the first access AP device; mapping the device information to large network data to generate a large network data map.

[0021] In the above solution, the network device can receive device information sent by the AP device, obtain device information such as the AP device's device identification and location, and generate a large network data graph by mapping the device information to the large network data. The device identification includes the AP device's device sequence number (SN). Specifically, the network device can generate the large network data based on the interference information. By mapping the AP device's device information to the large network data, the AP device's device identification, location, and other device information can be aligned with the AP device's interference information, thereby generating a large network data graph that includes the AP device information. By generating the large network data graph, the large network data can be visualized for the user, allowing the user to intuitively understand the interference experienced by the AP devices in the communication network. By mapping the device information to the large network data, the large network data can be visualized, facilitating timely adjustments to the AP devices based on the interference experienced by the AP devices. For example, based on the large network data graph, the user can understand the device information and interference information of any AP device, and thus configure the parameters of the AP device in real time using the generated configuration information, effectively reducing the interference experienced by the AP device and ensuring the communication quality of the AP device.

[0022] In a possible implementation, the network device includes any one of the following: an optical line terminal OLT, a network management platform, a broadband controller, and an element management system (EMS).

[0023] In the above solution, the network device can be an optical line terminal (OLT), a network management platform or element management system (EMS) located on the OLT, or a standalone device or apparatus located on the OLT, such as a broadband controller. In one possible implementation, the network device can also be implemented by other possible communication devices included in FTTR scenarios. For another example, the network device can also be a possible communication device or apparatus in the upper-layer network (as opposed to an AP device). The above communication method can be implemented in a variety of product forms, reducing the deployment difficulty of the communication network and enhancing compatibility.

[0024] 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, wherein the interference information indicates interference of the wireless signal sent by the second access AP device on the first access AP device; transmitting the interference information to a network device; and receiving configuration information generated by the network device in response to the interference information, wherein the configuration information indicates parameter configuration of the first access AP device.

[0025] In the above solution, the AP device can determine interference information based on wireless signals and send this information to the network device. Furthermore, the AP device receives configuration information generated by the network device in response to the interference information. While operations and maintenance personnel can typically adjust the configuration parameters of an AP device by inputting relevant information (e.g., configuration parameters) based on the communication status of a particular AP device, for example, by manually inputting the relevant configuration parameters through a network management platform, they can manually plan the configuration of a single AP device, which can alleviate the interference issues faced by the AP device to a certain extent. However, a communication network typically includes multiple AP devices, and interference may exist between AP devices. The interference experienced by any AP device often varies at different times. Therefore, relying solely on manual intervention is not sufficient to promptly determine interference between different AP devices, nor is it easy to calculate the optimal configuration parameters for any AP device, making centralized configuration of multiple AP devices impossible. With the above solution, the AP device can determine other AP devices causing interference based on acquired wireless signals, thereby determining interference information and sending this interference information to the network device. Furthermore, based on the received configuration information, the AP device can configure its parameters. Optionally, the AP device may configure parameters including one or more of the following: power, channel adjustment, bandwidth, air interface, flow 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 greater number of parameters based on the configuration information, which is not limited in this application. The above scheme can determine the interference information of the AP device and, through the generated configuration information, instruct the AP device to configure the corresponding parameters.

[0026] In one possible implementation, 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, and bandwidth.

[0027] In the above solution, an AP device (e.g., a first AP device) can determine the signal strength of the wireless signal received by the AP device (the first AP device), the device identifier of another AP device (e.g., a second AP device) that transmits the wireless signal, and / or service information of the AP device (e.g., the first AP device) based on the acquired wireless signal, thereby determining its own interference information. 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, and bandwidth. In one possible implementation, the device identifier of the other AP device includes a service set identifier (SSID). Thus, the AP device can determine other AP devices that are causing interference to itself based on 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 are causing interference to itself. Furthermore, wireless signals transmitted by other AP devices often interfere with the AP device, affecting the AP device's service status and, consequently, its service information (e.g., latency, packet loss rate). Through the above solution, the AP device can determine its own service information based on the acquired wireless signal, where the service information can represent the service status of the AP device. Thus, based on the service information, the AP device can determine its own interference information, which can be used to generate configuration information. Thus, through the above solution, the AP device can determine the signal strength of the received wireless signal, the device identification of other AP devices, and / or its own service information based on the wireless signal, and thus determine the interference information. Furthermore, the AP device can adaptively configure parameters based on the received configuration information generated in response to the interference information. This enables more optimal configuration of the AP device, thereby ensuring the communication quality of the AP device. Of course, after the AP device is configured, the device identification of other AP devices sending wireless signals or the service information of the AP device may vary at different times, that is, the interference information of the AP device may change. Therefore, 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.

[0028] In one possible implementation, before sending 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 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.

[0029] The AP device can then first determine whether the interference information (including the AP device's service information, the signal strength of the received wireless signal, and the device identifiers of other AP devices other than the AP device) meets one or more corresponding target conditions, and then selectively transmit the interference information to the network device. Taking the first target condition of exceeding a latency threshold as an example, when the AP device determines that its service information (i.e., latency) exceeds the latency threshold, it transmits the interference information to the network device. In one possible implementation, the interference information of an AP device is the same at different times, 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 (e.g., confirm whether the service information has changed) and then selectively transmit the interference information to the network device. For example, after the AP device determines that its 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 transmits the interference information to the network device. Through the above solution, the AP device can first determine the interference information and then selectively transmit the interference information to the network device, thereby effectively improving efficiency, reducing energy consumption, and lowering costs.

[0030] In a possible implementation, 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.

[0031] Then, in the above scheme, the AP device (e.g., the first access AP device) can periodically obtain wireless signals sent by other AP devices (e.g., the second access AP device), and then determine interference information based on the wireless signals. Optionally, the AP device can send the determined interference information to the network device. In one possible implementation, the communication status or configuration information of the AP device is different at different times. In this way, through the above scheme, the AP device can obtain wireless signals at a predetermined period, that is, at fixed intervals, and then determine interference information based on the wireless signals. Furthermore, by reporting the interference information to the network device, the network device can promptly determine the interference situation of the AP device at the current moment, and correspondingly generate corresponding configuration information, thereby configuring the parameters of the AP device in real time. Then, the AP device in the above scheme can periodically obtain interference information, and then perform parameter configuration in real time through the corresponding configuration information received.

[0032] In a possible implementation, the communication method further includes: sending device information to the network device, where the device information includes one or more of the following: a device identifier of the first access AP device and a location of the first access AP device.

[0033] In the above solution, the AP device can send device information including one or more of the following: the device identifier of the AP device and the location of the AP device to the network device. In one possible implementation, the device identifier of the AP device can be the serial number (SN) of the AP device. Of course, the device identifier of the AP device can also be a name or other device information capable of performing similar functions. Optionally, the network device can map this device information to macro-network data to generate a macro-network data graph. It will be readily understood that, based on other method examples of the present application, the network device can generate macro-network data based on interference information sent by the AP device. Thus, based on the above solution, the network device can also map the received device information to the generated macro-network data, such that device information such as the device identifier and location of the AP device corresponds to the interference information of the AP device, thereby generating a macro-network data graph including the device information of the AP device and the interference information of the AP device. The macro-network data graph can visualize the macro-network data to the user, allowing the user to intuitively understand the interference experienced by any AP device. Therefore, by sending the device information of the AP device to the network device, the above solution can visualize the macro-network data, allowing the user to clearly and intuitively understand the interference experienced by AP devices in the communication network.

[0034] 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 a computer program or instruction stored in a memory and control the interface circuit to perform the communication method described in any one of the first aspects.

[0035] 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 a computer program or instruction stored in a memory to control the interface circuit to perform the communication method according to any one of the second aspects.

[0036] 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, wherein the interference information indicates interference of a 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, wherein the configuration information indicates parameter configuration for the first access AP device; and the transceiver unit further configured to send the configuration information generated by the processing unit to the first access AP device.

[0037] 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, wherein the interference information indicates interference caused by the wireless signal sent by the second access AP device to the 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, wherein the configuration information indicates parameter configuration for the first access AP device.

[0039] Among them, the technical effects brought about by any design method in the third to seventh aspects mentioned above can refer to the technical effects brought about by different design methods in the first and second aspects mentioned above, and will not be repeated here.

[0047] This application will present various aspects, embodiments or features around 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 the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. In addition, a combination of these schemes 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 descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.

[0048] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0049] With the rapid development of communication technology, wireless transmission technology has been applied to various industries and has become one of the mainstream transmission technologies. Among them, Wi-Fi technology has gradually become the most widely used wireless transmission technology.

[0050] Fiber-to-the-x (FTTx) scenarios using Wi-Fi technology typically include multiple communication devices for wireless transmission. For example, scenarios such as FTTH and FTTR typically include multiple devices such as optical line terminals (OLTs) and optical network terminals (ONTs). For example, with reference to FIG1 , an embodiment of the present application provides a schematic diagram of a fiber-optic access network. A fiber-optic access network is also known as an optical access network (OAN). For ease of explanation, the fiber-optic access network shown in FIG1 is represented as OAN 10.

[0051] Specifically, as shown in Figure 1 , the OAN 10 includes an optical line terminal (OLT) (101 in Figure 1 ), an optical distribution network (ODN) (102 in Figure 1 ), and an optical network terminal (ONT) (103 in Figure 1 ). The OLT is typically located at the central office (e.g., a central control station). Optionally, the OAN may also include an optical network unit (ONU) located at the user side (also referred to as the terminal side). The ONT or ONU is typically located at different locations on the user side and performs similar functions. It is readily understood that the ONT and ONU perform similar functions and are generally considered components of the ONU. Therefore, for ease of explanation, in the OAN 10 shown in Figure 1 , only ONT 103 is used as an example on the user side, and this should not limit the types and number of devices included in the OAN. Figure 1 shows two ONTs: ONT 103-a and ONT 103-b.

[0052] Optionally, OAN 10 also includes an optical distribution network (ODN) connecting the OLT and the ONTs (see ODN 102 in FIG. 1 ). In one possible implementation, as shown in FIG. 1 , ODN 102 includes an optical splitter 102-1, which includes an input end, an output end a, and an output end b. The input end of optical splitter 102-1 is connected to OLT 101 via an optical fiber, the output end a of optical splitter 102-1 is connected to ONT 103-a via an optical fiber, and the output end b of optical splitter 102-1 is connected to ONT 103-b via an optical fiber.

[0053] Optionally, the ODN may further include a multi-stage optical splitter, that is, multiple optical splitters are provided to achieve multi-stage splitting of the optical signal. In other examples, the optical splitter may further include more or fewer output ports. For example, in conjunction with Figure 1, the ODN 102 may include only a single-stage optical splitter (e.g., optical splitter 102-1), or the ODN 102 may include two or more stages of optical splitters. Specifically, the function of the ODN 102 is to transmit the downstream optical signal of the OLT 101 to any ONT 103, and to transmit the upstream optical signal of any ONT 103 to the OLT 101. The embodiments of the present application do not limit the number of optical splitters included in the ODN, nor do they limit the number of output ports of each optical splitter.

[0054] Specifically, taking the downstream direction as an example, when OAN 10 is operating, OLT 101 transmits a downstream optical signal to ODN 102. The input port of optical splitter 102-1 in ODN 102 receives the downstream optical signal and transmits the downstream optical signal from output port a to ONT 103-a and from output port b to ONT 103-b. ONT 103-a and ONT 103-b receive the downstream optical signal and process it to obtain data. It should be understood that the transmission process of an optical signal in the downstream direction within OAN 10 shown in Figure 1 is used as an example only and should not limit the specific signal transmission process within the OAN.

[0055] Of course, in other embodiments, ONT 103 may also generate an upstream optical signal that needs to be sent to OLT 101. For example, when ONT 103-a generates an upstream optical signal, ONT 103-a will transmit the upstream optical signal to OLT 101 through the output end a of optical splitter 102-1 and the input end of optical splitter 102-1 in sequence.

[0056] As a fiber-optic access network, OAN 10 uses optical fiber (optical transmission medium) as a connection medium to enable signal transmission in both upstream and downstream directions. Referring to the OAN 10 shown in FIG1 , OLT 101, ODN 102, and ONT 103 are all connected via optical fibers, and these optical fibers can transmit both upstream and downstream optical signals. Of course, other types of communication networks, such as Ethernet, may also be deployed between the ONT on the user side and the user. The connection medium between the ONT and other types of communication networks includes optical transmission media such as optical fiber, as well as other non-fiber connection media that may implement corresponding functions to ensure that the ONT can connect to other types of communication networks. The embodiments of the present application do not limit this.

[0057] It should be noted that the optical fiber access network (OAN) 10 shown in Figure 1 is used as an example to illustrate possible application scenarios of wireless transmission technology. It is readily understood that wireless transmission technology has other possible application scenarios, and this should not limit the types of scenarios in which wireless transmission technology can be applied, or the network architecture in which it is applied. For example, in other examples, the OLT at the central office can also be used to connect to a network management platform (also known as a network management platform).

[0058] Typically, scenarios employing Wi-Fi technology may also include wireless communication devices such as routers (also known as AP devices or access devices). For example, referring to the OAN 10 shown in Figure 1, the user-side ONT 103 can also be implemented as an ONT with integrated AP device functionality. Generally speaking, operators often face a very large number of users, potentially even in the hundreds of millions. Correspondingly, the number of AP devices they need to handle is also very large. This means that any AP device in the communication network may face interference from different AP devices.

[0059] Based on the above, and with reference to FIG2 , an embodiment of the present application provides a schematic diagram of an application scenario for Wi-Fi technology. As shown in FIG2 , this scenario includes: an unknown network connected to an AP device; a network management platform connected to an OLT 11 and an OLT 12, wherein OLT 11 is connected to an ONT, and OLT 12 is connected to a master gateway, which is connected to slave gateways 21 and 22. This scenario also includes: other network management platforms. The master and slave gateways can be implemented using a variety of devices or apparatuses, such as AP devices.

[0060] Optionally, as shown in FIG2 , the architecture corresponding to the network management platform connected to the ONT or slave gateway can also be used to implement FTTR, and the embodiments of this application are not limited to this. It is understood that for ease of explanation, the scenario shown in FIG2 is used as an example only, and should not be used to limit the architecture of Wi-Fi technology application scenarios.

[0061] Specifically, in conjunction with the scenario shown in Figure 2, the AP device connected to the unknown network will interfere with other nearby AP devices (see the circular shaded area on the AP device). Multiple OLTs connected to the same network manager (see OLT 11 and OLT 12) will interfere with other nearby AP devices, and it is difficult for the network manager to determine the interference between the communication devices connected to the OLT (see ONTs and gateways). Multiple communication devices connected to the same OLT (such as OLT 12) (see slave gateway 21 and slave gateway 22) will interfere with other nearby AP devices, and it is difficult for the network manager to accurately obtain the corresponding interference situation in real time.

[0062] Based on the above, AP devices may be subject to interference from various devices, and it is difficult to accurately determine this, resulting in a poor user experience. Even interference between AP devices within the same FTTR network (referring to the network architecture where the network management platform is connected to the ONT and slave gateway) is difficult for network management to detect. For example, in the case of home networks, it is often difficult to determine the interference generated by AP devices in neighboring homes and other unknown networks. Therefore, it is difficult to properly plan the configuration of AP devices in the home network, resulting in frequent interference issues and a serious impact on the user experience.

[0063] For example, with reference to FIG3 , an embodiment of the present application provides a schematic diagram illustrating the distribution of interference in a communication network. As shown in FIG3 , the communication network includes nine AP devices (the rectangular boxes in FIG3 represent the spaces where the AP devices are deployed, which could be different rooms in a home or office, for example), labeled Rooms 1 through 9. Specifically, as shown in FIG3 , each AP device in the communication network will be subject to varying degrees of interference from other AP devices. The circular shaded areas in the figure represent the wireless signal coverage areas of each AP device, labeled Area A through Area I. The overlapping areas between two wireless signal coverage areas represent interference between AP devices. Taking Room 1 as an example, its AP device's wireless signal coverage area A overlaps with Room 2's wireless signal coverage area B, Room 6's wireless signal coverage area F, and Room 7's wireless signal coverage area G. This means that the AP device in Room 1 is subject to interference from at least three other AP devices. Of course, the AP device in Room 1 will also interfere with the AP devices in other rooms.

[0064] Typically, real-world network scenarios involve a vast number of APs. This means that the number of APs in a communication network is enormous. Any AP in the network may be subject to interference from numerous other APs, making it difficult to accurately determine the interference exposure of a specific AP. Consequently, interference between APs can be severe and frequent, resulting in a poor user experience.

[0065] To address these issues, the common practice is for operations personnel to manually plan interference between devices. Specifically, they manually input the relevant information and configure a specific AP through a network management platform (which can also be a router or other device). This manually plans the configuration of a specific AP to mitigate the interference faced by that AP. Alternatively, operations personnel can configure the AP through the AP's web interface (e.g., an ONT, an AP in an FTTR network, or a router).

[0066] However, the above solution is difficult to apply in many scenarios. For example, a user's home and a neighbor's home may use different operators for their home network deployment, making it difficult to determine the interference experienced by any AP device in the user's home network. Furthermore, since it's impossible to manually determine the interference between APs in real time, manual planning cannot achieve real-time configuration of AP devices. Furthermore, the above solution cannot centrally configure all AP devices in a home network through a corresponding control system. Therefore, if this solution is adopted, it will be difficult to specifically calculate the optimal configuration parameters for any AP device, and operations and maintenance personnel will be unable to centrally configure multiple AP devices, which will result in a huge workload for operations and maintenance personnel.

[0067] Therefore, there is an urgent need for a solution that can centrally configure AP devices in real time based on the interference they are experiencing, thereby improving the interference problem of AP devices and enhancing user experience.

[0068] Based on the above issues, an embodiment of the present application provides a schematic diagram of a communication method, as shown in Figure 4. The communication method provided in the embodiment of the present application will be described in detail below with reference to Figure 4. It should be noted that the control device and AP device are used as examples for description herein, and this should not limit the communication method provided in the embodiment of the present application. The communication method includes steps 401 to 407, which are described in detail as follows.

[0069] It should be noted that, based on the architecture shown in Figures 1 and 2, the network device in the embodiments of the present application may be an OLT (e.g., OLT 101 in Figure 1) or a network management platform (e.g., the network management platform in Figure 2), or a broadband controller. Of course, the network device may also be other devices or equipment capable of achieving its functions, and the embodiments of the present application do not limit this. For example, the network device may also be an element management system (EMS). It is not difficult to understand that the AP device in the embodiments of the present application may be an ONT (e.g., ONT 103-a in Figure 1). Of course, the AP device may also be other devices or equipment capable of achieving its functions, and the embodiments of the present application do not limit this.

[0070] For ease of explanation, in conjunction with FIG2 , the following embodiments of the present application use an OLT 11 as the control device and an ONT as the AP device. This should not limit the communication methods provided in the embodiments of the present application. It is readily understood that the OLT 11 and the ONT can achieve signal transmission via an optical network between them (see OAN 10 shown in FIG1 ).

[0071] Step 401: An AP device obtains wireless signals sent by other AP devices.

[0072] 4 , an AP device acquires wireless signals sent by other AP devices. Specifically, as shown in FIG2 , an ONT acquires wireless signals sent by other AP devices (eg, from a gateway 21 ).

[0073] In one possible implementation, the AP device periodically acquires wireless signals sent by other AP devices at a predetermined period. Optionally, the number of other AP devices may be one or more (greater than or equal to two), which is not limited in the embodiments of the present application.

[0074] Step 402: The AP device determines interference information.

[0075] 4 , the AP device determines interference information. Specifically, as shown in FIG2 , the ONT determines interference information based on the acquired wireless signal.

[0076] Optionally, the interference information of an AP device includes the signal strength of the wireless signal received by the AP device, the device identifiers of other AP devices other than 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, and bandwidth. Optionally, the device identifiers of other AP devices may be service set identifiers (SSIDs).

[0077] In one possible implementation, the AP device determines interference information including: 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 acquired wireless signals; and determines the interference information based on the service set identifier SSID of the other AP devices and the signal strength of the wireless signals received by itself. In other examples, the AP device determines interference information including: the AP device detects its own service information based on the acquired wireless signals; and determines the interference information based on the service information. For ease of explanation, the above two methods are merely two possible implementation methods for the AP device to determine interference information, and should not constitute a limitation on the method embodiments of the present application. The AP device can selectively determine the interference information through any one of the above methods, or can determine the interference information through multiple (two) of the above methods in parallel. For example, based on the acquired wireless signals, the AP device can determine the service set identifier SSID of other AP devices that send wireless signals and the signal strength of the received wireless signals and detect its own service information, thereby determining the interference information.

[0078] Step 403: The AP device sends interference information to the network device.

[0079] 4 , the AP device sends interference information to the network device. Specifically, as shown in FIG2 , the ONT sends interference information to the OLT 11. Optionally, the ONT reports the determined interference information to the OLT 11 via the optical network (see the OAN 10 shown in FIG1 ).

[0080] In one possible implementation, the AP device sends device information to the network device, where 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 another device identifier capable of implementing similar functions.

[0081] Step 404: The network device receives interference information.

[0082] 4 , the network device receives interference information. Specifically, as shown in FIG2 , the OLT 11 receives interference information reported by the ONT.

[0083] In conjunction with step 401, the AP device periodically obtains wireless signals sent by other AP devices at a predetermined period. Optionally, the network device periodically receives interference information sent by the AP device at a predetermined period.

[0084] Step 405: The network device generates configuration information.

[0085] As shown in Figure 4 , the network device generates configuration information. Specifically, as shown in Figure 2 , the OLT 11 generates configuration information in response to the interference information sent by the ONT. The configuration information is used to instruct parameter configuration of the AP device.

[0086] In one 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.

[0087] Optionally, the network device generates configuration information based on the interference condition based on the large network data. Correspondingly, the interference condition includes one or more of the following: data on the AP device affected by interference meets a first condition, data on a designated user of the AP device affected by interference meets a second condition, and data on a designated service of the AP device affected by interference meets a third condition.

[0088] Then, illustratively, the network device generates configuration information based on the large network data and interference conditions, including the following three methods:

[0089] Method (1): The network device determines the data on which the AP device is interfered with based on the large network data; determines that the data on which the AP device is interfered with meets the first condition, and generates configuration information.

[0090] Method (2): The network device determines the data of interference to the designated user of the AP device based on the large network data; determines that the data of interference to the designated user of the AP device meets the second condition, and generates configuration information.

[0091] Method (3): The network device determines the data of the AP device's designated service being interfered with based on the large network data; determines that the data of the AP device's designated service being interfered with meets the third condition, and generates configuration information. The expected user may be an important VIP user.

[0092] Exemplarily, the first condition may be that the data on the AP device being interfered with does not exceed the minimum threshold, that is, the data on the AP device being interfered with does not exceed its minimum threshold. The minimum threshold may be the minimum number of AP devices on which the AP device is interfered with. For another example, the second condition may be that the data on the designated user being interfered with does not exceed the minimum threshold, that is, the data on the designated user being interfered with does not exceed its minimum threshold. The minimum threshold may be the minimum value of an interference parameter indicating the degree of interference to the designated user of the AP device. Optionally, the third condition includes that the data on the AP device's designated service being interfered with does not exceed the minimum threshold, that is, the data on the AP device's designated service being interfered with does not exceed its minimum threshold. The minimum threshold may be the minimum value of the wireless signal strength indicating that the AP device's designated service is interfered with. Optionally, the above-mentioned first, second, and third conditions may also include other possible corresponding parameters or conditions, which are not limited in this application.

[0093] Based on the above three methods, the communication method provided in the embodiments of the present application can realize automatic control of interference to AP devices based on large network data, that is, it can generate configuration information according to various objectives (such as interference conditions) through the corresponding algorithm set to achieve the above process. For example, the above solution can be implemented by an AI graph segmentation algorithm, that is, according to the interference conditions, the corresponding configuration information is correspondingly generated by the AI ​​graph segmentation algorithm.

[0094] The network device can selectively generate configuration information through any of the above-mentioned methods, or can generate configuration information through multiple (two or three) of the above-mentioned methods in parallel. Of course, only a few 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.

[0095] Optionally, 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 map.

[0096] Step 406: The network device sends the generated configuration information to the AP device.

[0097] 4 , the network device sends the generated configuration information to the AP device. Specifically, as shown in FIG2 , the OLT 11 sends the generated configuration information to the ONT.

[0098] Step 407: The AP device receives the configuration information generated by the network device.

[0099] 4 , the AP device receives configuration information generated by the network device. Specifically, as shown in FIG2 , the ONT receives configuration information generated by the OLT 11 in response to interference information.

[0100] In a possible implementation, the AP device receives configuration information generated by the network device and performs parameter configuration according to the configuration information.

[0101] Then, based on steps 401-407, the network device can automatically generate large-scale network data in response to the interference information determined by one or more AP devices, generate configuration information based on the large-scale network data, and implement real-time configuration of any AP device through the configuration information. The above method can then enable the terminal side of the optical network (e.g., the AP device on the ONT side) and the central office side of the optical network (e.g., the network device on the OLT side) to automatically coordinate and implement automated tuning of AP devices based on virtual large-scale network data. In one possible implementation, the large-scale network data may be virtual data, that is, it does not include specific interference values ​​and other related specific numerical values.

[0102] In one possible implementation, an enterprise campus typically has multiple sets of FTTR equipment, where the FTTR equipment can be implemented by AP devices. Based on the above method, automated commissioning of multiple sets of FTTR equipment (for example, adjusting and testing the Wi-Fi parameters of the FTTR equipment) can be achieved, thereby effectively reducing interference and improving the service certainty of the equipment. For another example, for ordinary families, the above method can be used to centrally configure (interference from) AP devices in the home network, reducing interference and improving user experience. In addition, based on the above solution, centralized control of the interoperability of AP devices produced by different manufacturers (multiple AP devices) or communication networks of different operators (multiple operators) can be achieved, thereby improving device compatibility.

[0103] In conjunction with step 402, the AP device can determine interference information based on the device identifiers of other AP devices and the signal strength of received wireless signals (and / or its own service information). Typically, the interference experienced by an AP device varies at different times, so the AP device's interference information may change. Specifically, the SSIDs of other AP devices, the signal strength of received wireless signals, and its own service information may all change. Optionally, before sending the interference information to the network device, the AP device may determine that the interference information satisfies one or more of the following conditions: the service information of the AP device satisfies a first target condition, the device identifiers of other AP devices satisfy a second target condition, and the signal strength of the wireless signals received by the AP device satisfies a third target condition. In one possible implementation, the AP device periodically acquires wireless signals and determines interference information based on the acquired wireless signals. At a certain moment, if it determines that the service set identifier (SSID) of another AP device transmitting a wireless signal has changed, the AP device transmits the interference information to the network device. Alternatively, the AP device may determine the signal strength of the received wireless signal and / or its own service information before transmitting the interference information to the network device. In this way, the AP device can determine the interference information and then selectively send the interference information to the network device, thereby effectively reducing energy consumption.

[0104] In one possible implementation, in conjunction with step 404, the network device periodically receives interference information sent by the AP device. Exemplarily, in conjunction with step 407, if the AP device performs parameter configuration according to the configuration information, its communication state may change, and thus the interference information of the AP device may change. For example, this may be a change in the transmission of service information. Optionally, before generating configuration information in response to the interference information, the network device may determine that the interference information satisfies one or more of the following conditions: the service information of the AP device satisfies a first target condition, the device identifiers of other AP devices satisfy a second target condition, and the signal strength of the wireless signal received by the AP device satisfies a third target condition. For example, the first target condition is that the interference information is different from the interference information at a previous moment. If the network device determines that the service information of the AP device is different from the interference information at a previous moment, the configuration information is generated 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, thereby dynamically configuring the AP device in real time.

[0105] It should be noted that, in conjunction with step 403 above, the AP device can transmit interference information to the network device via a corresponding communication protocol. Accordingly, the network device can parse the received interference information via the corresponding communication protocol. In conjunction with step 406 above, the network device can transmit the generated configuration information to the AP device via a corresponding communication protocol. Accordingly, the AP device can parse the received configuration information via the corresponding communication protocol.

[0106] Specifically, the sending and receiving of signals (including interference information and configuration information) in the above method can be implemented through corresponding communication protocols. In one possible implementation, the communication protocol may be an 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 may 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 user terminal equipment wide area network management (technical report–069, TR069) protocol, and the extensible markup language (XML) configuration file method.

[0107] Typically, the network equipment 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 the parameters of the AP device based on the large network data. Of course, the network equipment can also implement the above functions through the MQTT protocol or other corresponding protocols, and the embodiments of the present application are not limited to this. Since the network equipment includes any of: OLT, network management platform, broadband controller network element management system EMS, the network equipment in the above process can also be other devices or equipment that can implement its functions, and the embodiments of the present application are not limited to 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 the Wi-Fi parameters of the AP device based on the large network data to achieve Wi-Fi tuning. In addition, in one possible implementation, 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., new configuration information) to the AP device in real time through the OMCI protocol or MQTT protocol.

[0108] In addition, based on step 405, the network device can visually present the generated large network data to the user through a large network data graph. For example, referring to FIG5 , an embodiment of the present application provides a schematic diagram of a possible large network data graph.

[0109] As shown in (1) in FIG5 , user 1 uses three communication networks, namely network 1, network 2 and network 3, wherein network 1 includes a master gateway and two slave gateways connected to the master gateway. Optionally, the AP device includes the above-mentioned master gateway and slave gateway. The number of devices and the connection relationship within network 2 and network 3 are similar to those in network 1 and will not be repeated 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 deployed in communication networks in different rooms. In this way, since the slave gateway of network 1 is close to the slave gateway of network 2, the interference between the two slave gateways is large (as shown by the dotted circle in (1) in FIG5 ), resulting in a large delay or even freeze in the cross-room roaming (switching to the slave gateway of network 2) of the communication device (for example, a terminal device) connected to the slave gateway of network 1 for communication, which seriously affects the user's network experience.

[0110] In conjunction with (2) in FIG. 5 , based on the embodiment of the present application, macro-network data can be generated. Furthermore, by mapping device information (e.g., device serial number, location) of the AP device to the generated macro-network data, a macro-network data graph can be generated. Optionally, the AP device herein includes a master gateway and a slave gateway.

[0111] As shown in (3) in FIG5 , the three communication networks used by user 2 all include a master gateway and two slave gateways connected to the master gateway. The communication network used by user 3 includes a master gateway and two slave gateways connected to the master gateway. Among them, based on the above-mentioned method embodiment of the present application, configuration information can be generated based on the interference conditions based on the large network data. Specifically, in combination with the method (2) in step 405, by determining the data of the interference to the designated user of the AP device (such as the VIP user in (3) in FIG5 ), configuration information can be generated to ensure the communication effect of the VIP user using the AP device. In combination with the method (3) in step 405, by determining the data of the interference to the designated service of the AP device (such as the live broadcast application in (3) in FIG5 ), configuration information can be generated to ensure the communication effect of the live broadcast application using the AP device.

[0112] For example, with reference to FIG6 , 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, wherein the interference information is used to indicate 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 based on the interference information received by the transceiver unit 601, wherein the configuration information is used to indicate parameter configuration for the first access AP device; and the transceiver unit 601 is further configured to send the configuration information generated by the processing unit to the first access AP device.

It is understood that the communication device can directly refer to the description of the functions and effects of steps 404 to 406 in the communication method shown in FIG. 4 , and will not be further elaborated here.
