[0002] With the continuous development and popularization of wireless network technology, users' demand for wireless networks is also increasing. In various scenarios such as home, office environment and public places, the coverage, stability and efficiency of wireless networks have become particularly important. Especially in applications such as smart home, high-definition video transmission, online games and real-time live broadcast, users' demand for high bandwidth, low latency and stable connection of the network is becoming more and more urgent.

However, with the increase in the number of users and the diversification of network applications, a single AP often cannot meet the needs of users, and problems such as network congestion and insufficient signal coverage are prone to occur. In order to solve these problems, solutions for multi-AP collaboration have been proposed in recent years, such as the FTTR (Fiber To The Room) network environment. The FTTR network is a new type of home network solution that introduces optical fiber into each room and combines multiple wireless access point devices to achieve a high-bandwidth, low-latency, and seamless coverage wireless network environment. The FTTR network can significantly improve the network coverage and signal quality, meeting users' needs for high-quality network connections.

DETAILED DESCRIPTION

[0019] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0020] The embodiment of the present invention provides a method and device for roaming switching in an FTTR network environment to solve the technical problem that the traditional roaming switching method usually only relies on signal strength for selection, which easily leads to network interruption and increased delay during the switching process.

[0021] First, the present invention provides a method for roaming switching in an FTTR network environment, and the method for roaming switching in an FTTR network environment is applied to a terminal device. The method for roaming switching in an FTTR network environment can be based on an FTTR system, an FTTR-B system, or a broadband converged terminal. Figure 1 , Figure 1 FIG. 2 is a schematic flow chart showing a method for roaming switching in an FTTR network environment provided by the present invention. Figure 1 As shown, the method for roaming switching in the FTTR network environment may include the following steps: Step 101: When the first signal strength of the current access point device is lower than the first threshold, the terminal device sends a traffic type to other access point devices; the traffic type includes a video traffic type, an online game traffic type, a web page traffic type, and a real-time live broadcast traffic type; When the terminal device detects that the first signal strength of the current access point device is lower than the preset first threshold, the terminal device prepares for roaming switching. The first threshold is a set signal strength critical value. When the signal strength is lower than this value, it indicates that the signal quality of the current access point has deteriorated, which may affect network performance.

[0022] The terminal device sends the information of the traffic type currently in use to other access point devices. Traffic types include but are not limited to different categories such as video traffic, online game traffic, web traffic and real-time live broadcast traffic. These traffic types are sent to let other access point devices understand the needs of the terminal device and provide more matching network services.

[0023] Step 102: receiving a roaming priority returned by the other access point device according to the traffic type; wherein the roaming priority is calculated based on the traffic type and network parameters, and the network parameters include bandwidth margin, current number of connections, delay, and packet loss rate of the other access point device; Other access point devices return corresponding roaming priorities based on the received traffic type information. These priorities are calculated based on the traffic type and the network parameters of each access point device. Network parameters include but are not limited to bandwidth margin, current number of connections, latency, and packet loss rate.

[0024] Bandwidth margin refers to the available bandwidth of the current access point device. Current number of connections refers to the number of terminals currently connected to the access point device. Latency refers to the network delay of the access point device. Packet loss rate refers to the packet loss rate of the access point device. These parameters together determine the quality of service that each access point can provide, thereby forming the roaming priority.

[0025] Step 103: Filtering a target access point device from a plurality of other access point devices according to the roaming priorities corresponding to each of the plurality of other access point devices and the second signal strengths corresponding to each of the plurality of other access point devices; The terminal device selects the most suitable target access point device from the multiple access point devices according to the roaming priorities and the corresponding second signal strengths returned by the multiple other access point devices. The second signal strength refers to the current signal strength of the other access point devices. The screening process comprehensively considers the roaming priority (i.e., network service quality) and signal strength to select the best access point device for switching.

[0026] Specifically, step 103 specifically includes step 1031 to step 1032: Step 1031: Calculate a roaming score according to the roaming priority corresponding to other access point devices and the second signal strength corresponding to other access point devices; Specifically, step 1031 specifically includes: substituting the roaming priority corresponding to other access point devices and the second signal strength corresponding to other access point devices into function one to obtain a roaming score; The function 1 is: in, represents the roaming score of the i-th other access point device, represents the roaming priority of the i-th other access point device, Indicates the maximum roaming priority of all other access point devices. represents the signal strength of the i-th other access point device, Indicates the minimum signal strength among all other access point devices. Indicates the maximum signal strength among all other access point devices. represents the first weight parameter, represents the second weight parameter, represents the first adjustment index, Represents the second adjustment index.

[0027] This part combines roaming priority and signal strength through normalization and nonlinear adjustment to give a comprehensive score. and The relative influence of priority and signal strength can be adjusted.

[0028] This section combines signal strength and priority to ensure that a high-priority access point is not scored too high when its signal strength is weak, nor is it scored too low when a low-priority access point is strong.

[0029] Final Rating It is the sum of the above two parts, taking into account the roaming priority and signal strength of the access point, ensuring that the device can make better decisions when switching between different access points. , , and The value of can be used to optimize function 1 to adapt to the specific network environment and requirements.

[0030] Step 1032: Use other access point devices corresponding to the maximum roaming score as the target access point devices.

[0031] In the embodiment corresponding to step 1031 to step 1032, by calculating the roaming score, the two key factors of roaming priority and signal strength are comprehensively considered to ensure that the selected access point not only has a high signal strength but also can provide good network service quality. This method avoids potential problems caused by relying only on signal strength or network parameters.

[0032] Step 104: Switch the current access point device currently connected to the terminal device to the target access point device.

[0033] The terminal device switches the access point device it is currently connected to to the selected target access point device, thus achieving seamless roaming. This process ensures that the terminal device can quickly switch to a suitable access point when the signal strength is insufficient, reducing network interruption and delay.

[0034] As an optional embodiment of the present application, after step 104, it also includes: taking the target access point device as the current access point device, and looping the step of sending the traffic type by the terminal device to other access point devices when the first signal strength of the current access point device is lower than the first threshold and subsequent steps (i.e., looping steps 101 to 104).

[0035] In the embodiments corresponding to steps 101 to 104, the traditional roaming switching method mainly relies on signal strength for selection, which is prone to network interruption and increased delay during the switching process. In this method, when the first signal strength of the current access point device is lower than the first threshold, the terminal device sends traffic type information to other access point devices, so that the access point can respond according to the actual needs of the terminal device, thereby effectively reducing network interruption and delay during the switching process. Different traffic types (such as video traffic, online game traffic, web traffic and real-time live broadcast traffic) have different requirements for parameters such as network bandwidth, delay and packet loss rate. In this method, by calculating the roaming priority according to the traffic type and network parameters (including bandwidth margin, current number of connections, delay and packet loss rate), network resources can be allocated and utilized more efficiently to ensure that network requirements in different application scenarios are met. In the switching decision process, not only the signal strength of other access point devices is considered, but also the roaming priority calculated by each access point device according to the traffic type is combined. After considering multiple factors, the terminal device can screen out the best target access point device to ensure the accuracy and stability of the switching. For applications that have high requirements for network quality, such as video streaming, online games, and real-time live broadcasts, this method significantly reduces problems such as lag and delay caused by network switching by optimizing the switching process, thereby enhancing the user experience.

[0036] Secondly, the present invention provides a method for roaming switching in a FTTR network environment, and the method for roaming switching in a FTTR network environment is applied to other access point devices. The method for roaming switching in a FTTR network environment can be based on a FTTR system, a FTTR-B system or a broadband converged terminal. The method for roaming switching in a FTTR network environment may include the following steps: Step 201: receiving a traffic type sent by a terminal device; Step 202: Match multiple preset weight coefficients corresponding to the traffic type; the multiple preset weight coefficients include a first weight coefficient corresponding to the bandwidth margin, a second weight coefficient corresponding to the current number of connections, a third weight coefficient corresponding to the delay, and a fourth weight coefficient corresponding to the packet loss rate; Depending on the type of traffic sent by the terminal device, the system will match the corresponding preset weight coefficients. These weight coefficients represent the importance of different network parameters under the traffic type. For example, for video calls, the weight coefficient of latency may be relatively large, while for file downloads, the weight coefficient of bandwidth margin may be larger. The weight coefficients can be set based on the actual application scenario.

[0037] Step 203: Calculate the roaming priority according to the bandwidth margin, the current number of connections, the delay, the packet loss rate, the first weight coefficient corresponding to the bandwidth margin, the second weight coefficient corresponding to the current number of connections, the third weight coefficient corresponding to the delay, and the fourth weight coefficient corresponding to the packet loss rate; Specifically, step 203 specifically includes: substituting the bandwidth margin, the current number of connections, the delay, the packet loss rate, the first weight coefficient corresponding to the bandwidth margin, the second weight coefficient corresponding to the current number of connections, the third weight coefficient corresponding to the delay, and the fourth weight coefficient corresponding to the packet loss rate into function 2 to obtain the roaming priority; The second function is: in, Indicates roaming priority. Indicates the bandwidth margin, Indicates the current number of connections. Indicates delay, Indicates the packet loss rate, represents the first weight coefficient corresponding to the bandwidth margin, Indicates the second weight coefficient corresponding to the current number of connections, represents the third weight coefficient corresponding to the delay, Indicates the fourth weight coefficient corresponding to the packet loss rate, Indicates the preset threshold value, Indicates milliseconds, Indicates the judgment condition. It means the relationship between the two is and.

[0038] Among them, function 2 uses a piecewise function to adjust the priority calculation method according to different network conditions: ①Low latency conditions ( ): In the case of low latency, priority is mainly determined by bandwidth margin and the number of current connections. Bandwidth margin is given a higher weight, and the current number of connections The effect of is to prevent the denominator from being zero by adding 1.

[0039] ② Medium delay condition ( ): When the delay is between 50 and 100 milliseconds, in addition to the influence of bandwidth margin and current number of connections, a value proportional to the delay needs to be deducted. This proportional value is calculated by and Expressed, reflecting the negative impact of delays on priorities.

[0040] ③ High latency and high packet loss rate conditions ( ): When the delay exceeds 100 milliseconds and the packet loss rate is higher than 1, the priority is further deducted by a value proportional to the packet loss rate based on the medium delay. This proportional value is calculated by and It is expressed,reflecting the negative impact of packet loss rate on priority.

[0041] ④High latency but low packet loss rate conditions ( ): ,When the delay exceeds 100 ms but the packet loss ratio is not high (less than or equal to 1), only the negative impact of the delay is considered.

[0042] Function 2 can flexibly adjust the priority under different network conditions: bandwidth margin and current number of connections are considered in all conditions, reflecting the network resource usage. The impact of latency begins to be significant when the latency exceeds 50 milliseconds and reaches its maximum when the latency exceeds 100 milliseconds. The impact of packet loss rate is only considered when the latency exceeds 100 milliseconds and the packet loss rate is higher than 1, to reflect network stability issues in extreme cases. This piecewise function design allows roaming priority to be dynamically adjusted according to actual network conditions, thereby optimizing the network performance experience.

[0043] Step 204: Send the roaming priority to the terminal device; the roaming priority is used to screen a target access point, and switch the current access point device currently connected to the terminal device to the target access point device.

[0044] In the embodiment corresponding to step 201 to step 204, by receiving the traffic type information sent by the terminal device, personalized processing can be performed according to different traffic requirements (such as video streaming, audio streaming, data transmission, etc.), thereby improving the utilization efficiency of network resources and user experience. Four key indicators, namely bandwidth margin, current number of connections, delay and packet loss rate, are introduced, and a preset weight coefficient is matched for each indicator, and the influence of multiple factors on roaming switching is comprehensively considered, thereby avoiding the one-sidedness of single signal strength selection, thereby achieving more accurate and intelligent roaming decisions. By combining actual network status information such as bandwidth margin, current number of connections, delay and packet loss rate, the roaming priority is calculated to ensure that when the user terminal device switches, the optimal target access point device is preferentially selected, thereby reducing network interruption and delay during the switching process. The calculated roaming priority is sent to the terminal device in a timely manner, so that the terminal device can screen the target access point according to the real-time network status and priority, thereby ensuring a smooth and efficient switching process. By reasonably allocating and utilizing network resources, the packet loss rate and delay during the switching process are reduced, and the performance and stability of the overall network are improved, which is particularly suitable for high-density user scenarios and application environments with high bandwidth requirements. By reducing network interruptions and delays during roaming switching, users can continue to enjoy high-quality network services during mobility, thereby improving user satisfaction. In summary, the roaming switching method under the FTTR network environment of the present invention realizes more intelligent, stable and efficient roaming switching through multi-dimensional weight matching and dynamic priority calculation, significantly improving network performance and user experience.

[0045] like Figure 2 The present invention provides a roaming switching device 2 in a FTTR network environment, see Figure 2 , Figure 2 A schematic diagram of a roaming switching device in a FTTR network environment provided by the present invention is shown. Figure 2 A roaming switching device in a FTTR network environment includes: The judging unit 21 is configured to, when the first signal strength of the current access point device is lower than the first threshold, cause the terminal device to send a traffic type to other access point devices; the traffic type includes a video traffic type, an online game traffic type, a web page traffic type, and a real-time live broadcast traffic type; A first receiving unit 22 is used to receive the roaming priority returned by the other access point device according to the traffic type; wherein the roaming priority is calculated based on the traffic type and network parameters, and the network parameters include bandwidth margin, current number of connections, delay and packet loss rate of other access point devices; A screening unit 23, configured to screen a target access point device from a plurality of other access point devices according to the roaming priorities corresponding to each of the plurality of other access point devices and the second signal strengths corresponding to each of the plurality of other access point devices; The roaming unit 24 is used to switch the current access point device currently connected to the terminal device to the target access point device.

[0046] The present invention provides a device for roaming switching in an FTTR network environment. The traditional roaming switching method mainly relies on signal strength for selection, which is prone to network interruption and increased delay during the switching process. In this method, when the first signal strength of the current access point device is lower than the first threshold, the terminal device sends traffic type information to other access point devices, so that the access point can respond according to the actual needs of the terminal device, thereby effectively reducing network interruption and delay during the switching process. Different traffic types (such as video traffic, online game traffic, web traffic and real-time live broadcast traffic) have different requirements for parameters such as network bandwidth, delay and packet loss rate. In this method, by calculating the roaming priority according to the traffic type and network parameters (including bandwidth margin, current number of connections, delay and packet loss rate), network resources can be allocated and utilized more efficiently, ensuring that network requirements in different application scenarios are met. In the switching decision process, not only the signal strength of other access point devices is considered, but also the roaming priority calculated by each access point device according to the traffic type is combined. After considering multiple factors, the terminal device can screen out the best target access point device to ensure the accuracy and stability of the switching. For applications that have high requirements for network quality, such as video streaming, online games, and real-time live broadcasts, this method significantly reduces problems such as lag and delay caused by network switching by optimizing the switching process, thereby enhancing the user experience.
