DETAILED DESCRIPTION

[0018] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] See attached Figure 1 , attached Figure 1This is a schematic diagram of the structure of an electronic device of the hardware operating environment involved in the embodiment of the present application. The electronic device may include: a processor 101, such as a central processing unit (CPU), a communication bus 102, a user interface 104, a network interface 103, and a memory 105. Among them, the communication bus 102 is used to realize the connection and communication between these components. The user interface 104 may include a display (Display), an input unit such as a keyboard (Keyboard), and the user interface 104 may also include a standard wired interface and a wireless interface. The network interface 103 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 105 may optionally be a storage device independent of the aforementioned processor 101. The memory 105 may be a high-speed random access memory (RAM) memory, or it may be a stable non-volatile memory (NVM), such as at least one disk storage. The processor 101 may be a general-purpose processor, including a central processing unit, a network processor, etc., or it may be a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component.

[0020] Those skilled in the art will appreciate that Figure 1 The structure shown in the figure does not constitute a limitation on the electronic device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0021] As attached Figure 1 As shown, the memory 105 as a storage medium may include an operating system, a network communication module, a user interface module, and a data transmission device based on FTTR-B.

[0022] In the attached Figure 1 In the electronic device shown, the network interface 103 is mainly used for data communication with the network server; the user interface 104 is mainly used for data interaction with the user; the processor 101 and the memory 105 in the present application can be set in the electronic device, and the electronic device calls the FTTR-B based data transmission device stored in the memory 105 through the processor 101, and executes the FTTR-B based data transmission method provided in the embodiment of the present application.

[0023] See attached Figure 2 Based on the hardware device of the foregoing embodiment, the embodiment of the present application provides a data transmission method based on FTTR-B, comprising the following steps: S10: In the data transmission process based on FTTR-B, in response to a network performance optimization instruction, a router used for data transmission is migrated from a current router to a non-target router.

[0024] In the specific implementation process, the network performance optimization instruction can be initiated by the user. For example, when a user uses a terminal device such as a computer or a mobile phone to access the network and receives transmitted data, and there is an interruption, lag, slow receiving speed, etc. during the transmission process, the method of the present application is started by issuing a network performance optimization instruction. Since the instruction initiated by the user is for the router currently used by the user, the network performance optimization instruction is performed on the router currently used.

[0025] The non-target router is equivalent to a backup router, which can be in two forms. One is a router that completely replaces the current router in terms of function and location. This router is not usually used as a backup router. It is only used when the current router needs to be disconnected. All data transmission can be directly carried out through this router. Of course, other devices connected to the current router also need to be migrated together. Another way is to use an existing working router, and the migration method is the same as the above method. This migration will not affect the user's work, because in the scenario of FTTR-B technology application, there are multiple routers. Each office and conference room of the enterprise will be equipped with a router. In larger offices, multiple routers will be set up. The devices are grouped and connected to different routers to ensure that a single router will not have too many accesses, so this temporary and short-term device migration access will not have a major impact.

[0026] S20: Determine the target channel according to the wireless channel information available to the current router.

[0027] In the specific implementation process, before restarting the router, some related parameters are reset, and the first is to re-determine the connected wireless channel. The network performance problem may be caused by the mismatch or inappropriateness of the applied wireless channel, so the channel can be re-determined within the available wireless channel range. The wireless channel information can be obtained by scanning, that is, according to the wireless channel information available to the current router, before determining the target channel, the method also includes: Scan the usage of wireless channels within the target range of the current router to obtain the scanning results; According to the scanning results, the wireless channel information available for the current router is obtained.

[0028] You can use the router's management interface or professional tools to scan nearby wireless channels, sort out the scan results, and filter out the parts that are available to the router. Furthermore, in order to reduce interference and improve signal quality, select the idle or least interfered channel among the available wireless channels as the target channel for connection, that is, determine the target channel based on the wireless channel information available to the current router, including: According to the wireless channel information available to the current router, determine the target channel with the least interference.

[0029] In one embodiment, after determining that the channel with the least interference is the target channel according to the wireless channel information available to the current router, the method further includes: Get the supported frequency bands of the current router. If the supported frequency bands include the 5 GHz band and the target channel is the 2.4 GHz band, enable the 5 GHz band.

[0030] In the specific implementation process, for the 2.4GHz frequency band, the commonly used non-overlapping channels are 1, 6, and 11, and these channels should be given priority. If the router supports the 5GHz frequency band, since this frequency band has less interference and a large number of channels, the 5GHz frequency band can be turned on to reduce interference in the 2.4GHz frequency band and further improve transmission quality.

[0031] S30: Determine the target transmission power of the current router according to the actual coverage requirement of the current router.

[0032] In the specific implementation process, according to the actual coverage requirements, the router transmission power is reset and appropriately adjusted to reduce interference with other devices and improve signal quality. The reset transmission power is the target transmission power. Since the application scenarios of FTTR-B technology are relatively complex, with many floor changes, walls, corners, etc., and some office areas are also relatively large, in order to ensure that the signal coverage does not affect the network performance, wireless access points can be added, that is, according to the actual coverage requirements of the current router, before determining the target transmission power of the current router, the method also includes: Add wireless access points to ensure that the signal coverage of the current router fully meets the actual coverage requirements.

[0033] In the specific implementation process, a wireless access point is also called an AP, which is an access point of a wireless network, commonly known as a "hotspot". There are mainly integrated routing, switching and access devices and pure access point devices. The integrated device performs access and routing work, and the pure access device is only responsible for the access of wireless clients. Pure access devices are usually used as wireless network extensions, connected to other APs or main APs to expand the wireless coverage, and the integrated device is generally the core of the wireless network. Add wireless access points such as repeaters and extenders in large houses or complex environments to expand the signal coverage and reduce signal blind spots, at least to ensure that the expanded signal coverage can meet the actual coverage requirements.

[0034] When adding wireless access points, you need to comprehensively consider the use environment structure, such as office area, wall material, user density, signal interference and other factors, and reasonably plan the number and location of wireless access points to ensure signal coverage and network performance. That is, before adding wireless access points to ensure that the signal coverage of the current router fully meets the actual coverage requirements, the method also includes: Determine the number and location of wireless access points based on the environment in which you are using them.

[0035] For example, microwave ovens and Bluetooth devices may generate interference signals, so their locations need to be planned reasonably; complex layouts, such as multiple rooms or compartments, may require more access points to bypass obstacles.

[0036] S40: Restart the current router, connect with the target channel and operate with the target transmission power to obtain the target router.

[0037] In the specific implementation process, after completing the reset of the above parameters, restart the router to clean up the cache and restore it to a better state, thereby improving network performance. In subsequent use, a regular autonomous restart cycle can be set according to historical error reports. Restarting can be done through the restart switch on the router or through remote control of a control device connected to the router. The current router after the reset and restart is the target router.

[0038] S50: Migrate the router used for data transmission from the non-target router to the target router to continue data transmission based on FTTR-B.

[0039] In the specific implementation process, after the current router is reset and restarted, the network performance problem is improved, and the data transmission needs to be migrated back to the original router, that is, the target router. The migration is similar to the first step of migration, and the device is migrated out and connected back to the original router. At the migrated node, data loss may occur, so a retransmission time period needs to be set, that is: the router used for data transmission is migrated from the current router to the non-target router, and before the router used for data transmission is migrated from the non-target router to the target router, the method also includes: Determine the retransmission time period before and after migration; Migrating a router used for data transmission from a current router to a non-target router, and migrating a router used for data transmission from a non-target router to a target router, including: According to the retransmission time period, the router used for data transmission is migrated from the current router to the non-target router, and the router used for data transmission is migrated from the non-target router to the target router.

[0040] In the specific implementation process, the retransmission time period, that is, the data transmission after the migration needs to be repeated for a period of time, and the data transmitted in a period of time before the migration time point is transmitted again, or the transmission continues from a time point before the migration time point. The time between the migration time point and this time point is the retransmission time period. The size of this time period can be adjusted according to the amount of transmitted data and the transmission rate.

[0041] In this embodiment, during the process of data transmission based on the FTTR-B technology, processing is performed only when a network performance optimization instruction is obtained. First, the router currently being used for data transmission is migrated to other routers to keep data transmission uninterrupted and not affect the normal work of users. Then, the causes of the network performance problem are not checked one by one, but the transmission channel and the transmission power of the router are re-determined through a complete reset to avoid interference and improve signal quality. Finally, the current router is restarted to eliminate the cache to improve network performance. After completion, the data transmission is migrated back to the original router to continue to maintain the original FTTR-B solution, thereby improving the data transmission effect based on FTTR-B.

[0042] See attached Figure 3 Based on the same inventive concept as in the above-mentioned embodiment, the embodiment of the present application further provides a data transmission device based on FTTR-B, including: A first migration module, the first migration module is used to migrate the router used for data transmission from the current router to the non-target router in response to the network performance optimization instruction during the data transmission process based on FTTR-B; A first determination module, the first determination module is used to determine a target channel according to wireless channel information available to the current router; A second determination module, the second determination module is used to determine the target transmission power of the current router according to the actual coverage range requirement of the current router; The restart module is used to restart the current router, connect with the target channel and operate with the target transmission power to obtain the target router; The second migration module is used to migrate the router used for data transmission from the non-target router to the target router to continue the data transmission based on FTTR-B.
