Description

Technical Field

[0001] This invention relates to the field of roaming technology, and in particular to a network scheduling method, apparatus, device, and storage medium based on a PON network. Background Technology

[0002] With the widespread adoption of wireless networks, users are increasingly demanding smooth roaming, leading to the widespread application of PON-based network scheduling technology in scenarios such as Fiber to the Room (FTTR), enterprise-level Fiber to the Room-Business (FTTR-B), and broadband converged terminals.

[0003] In existing PON-based network scheduling processes, the Received Signal Strength Indicator (RSSI) is typically used to directly select a suitable wireless node as the terminal's working node, or node switching is performed for the terminal. In other words, current network scheduling technologies usually use node busy levels as a benchmark to achieve network scheduling and ensure terminal communication quality. This can lead to a situation where multiple wireless nodes are routed by the same routing module, potentially causing the routing module to become overloaded and resulting in poor communication quality for the corresponding wireless nodes, thus impacting user experience. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] The network scheduling method based on PON network provided in this embodiment of the invention can be applied to the main gateway of a roaming network. The main gateway has the function of a wireless control node (Access Controller, AC) in the network, or is linked with an AC. This disclosure does not limit this, so that the main gateway can be responsible for the configuration, routing management and forwarding of wireless access points (APs).

[0019] The roaming network can be a wireless mesh network or an improved wireless mesh network, but is not limited thereto. This disclosure does not limit the applicable equipment for the networking scheduling method based on PON networks.

[0020] In one embodiment, such as Figure 1 As shown, a network scheduling method based on a PON network is provided. Taking the application of this method in the main gateway as an example, the method includes the following steps: S101: In response to the routing assignment request from the wireless node, obtain the number of terminals and traffic parameters corresponding to multiple candidate routing modules.

[0021] S102: Determine the target routing module from multiple candidate routing modules based on the number of terminals and traffic parameters.

[0022] S103: Based on the target routing module, it provides service support for wireless nodes.

[0023] Among them, wireless nodes usually refer to the aforementioned wireless access nodes (APs).

[0024] The route allocation request is used by the wireless node to request the main gateway to allocate a route module, so as to allocate a network address for the wireless node and / or to forward packets for the wireless node.

[0025] The wireless allocation request may be sent when the wireless node first accesses the network, or when the wireless node detects that the packet forwarding is slow, or when the wireless node is reconfigured; this disclosure does not limit the scope of the request.

[0026] The traffic parameter can indicate the number of packets processed by the candidate routing module per unit time, or it can indicate the average bandwidth of the candidate routing module per unit time. This disclosure does not limit the specific parameters indicated by the traffic parameter.

[0027] As an example, in step S101, in response to the routing allocation request sent by the wireless node, the main gateway can obtain the number of terminals and traffic parameters corresponding to multiple candidate routing modules through network protocols, device interfaces, data collection, etc., where the candidate routing modules can be any routing module managed by the main gateway.

[0028] As an example, in step S102, the main gateway can determine the busy level of each candidate routing module based on the number of terminals and traffic parameters obtained, and then determine the target routing module from each candidate routing module based on the busy level of each candidate routing module.

[0029] As an example, in step S103, the main gateway can use the determined target routing module to provide network address configuration, routing forwarding and other service support to the wireless node that sends the route allocation request, so that the wireless node can provide network services to the corresponding terminal.

[0030] In summary, in this example, by responding to a routing allocation request from a wireless node, the number of terminals and traffic parameters corresponding to multiple candidate routing modules are obtained; based on the number of terminals and the traffic parameters, a target routing module is determined from the multiple candidate routing modules; and based on the target routing module, service support is provided to the wireless node. This method determines the busy level of each candidate routing module by obtaining terminal and traffic data supported by the candidate routing modules, thereby balancing the load among the various routing modules in the network and improving the network quality of each wireless node and terminal in the network.

[0031] As an example, in step S103, when a wireless node joins the network for the first time, or when a wireless node needs to be reconfigured with a network address, the main gateway can use a determined target routing module to assign a network address to the wireless node.

[0032] As an example, in step S103, when the wireless node is in a working state, the main gateway can use the determined target routing module to route and forward the received packets for the wireless node, so as to provide service support for the wireless node.

[0033] like Figure 2As shown, step S102, which involves determining the target routing module from multiple candidate routing modules based on the number of terminals and traffic parameters, includes: S201: Determine the busy parameters of multiple candidate routing modules based on the ratio of traffic parameters to the number of terminals.

[0034] S202: Determine the target routing module from multiple selected modules based on the busyness parameter.

[0035] As an example, in step S201, the main gateway can determine the busyness parameter of each candidate routing module by the ratio between the traffic parameter and the number of terminals corresponding to each candidate routing module.

[0036] For example, let t represent the traffic parameter and n represent the number of terminals, then the busyness parameter y of the candidate routing module can be expressed as: .

[0037] It should be understood that the higher the determined busyness parameter, the busier and more loaded the candidate routing module is.

[0038] As an example, in step S201, the busy level of each candidate routing module can be determined based on the busy parameter, and the candidate routing module with a lower busy level can be selected as the target routing module of the wireless node to provide corresponding service support for the wireless node.

[0039] Optionally, in step S202, the candidate routing module with the smallest busyness parameter can be determined as the target routing module to provide corresponding service support for the wireless node.

[0040] Optionally, in step S202, when there are multiple candidate routing modules with a busyness parameter less than a preset busyness threshold, it indicates that the load of the multiple candidate routing modules is low. Therefore, any candidate routing module can be selected from the multiple candidate routing modules with a busyness parameter less than the preset busyness threshold as the target routing module.

[0041] Optionally, in step S203, when there are multiple candidate routing modules with busyness parameters less than a preset busyness threshold, the number of terminals of the candidate routing modules with busyness parameters less than the preset busyness threshold can be further compared, so as to determine the candidate routing module with the smallest number of terminals as the target routing module, thereby further improving the service quality of the wireless node.

[0042] In summary, in this example, the busyness parameters of multiple candidate routing modules are determined based on the ratio of traffic parameters to the number of terminals; based on the busyness parameters, the target routing module is selected from the multiple selected modules. This application evaluates the busyness of each candidate routing module from multiple dimensions according to the number of terminals and traffic parameters corresponding to each candidate routing module, thereby selecting the candidate routing module with lower busyness (i.e., lower load) as the target routing module to provide service support for wireless nodes. This effectively avoids the situation where poor network service of wireless nodes is caused by high load of routing modules, and improves network quality and stability.

[0043] like Figure 3 As shown, before step S101 or in step S103, the PON-based network scheduling method further includes: S301: Obtain the received signal strength parameters of the terminal at multiple times, including the current time and multiple historical times; S302: Based on the preset initial received signal strength threshold and the received signal strength parameters at each time moment, determine the fused received signal strength parameters of the terminal at each time moment; S303: Based on multiple fused received signal strength parameters, determine the updated received signal strength threshold of the terminal at the current moment; S304: If the received signal strength parameter of the terminal at the current moment is less than or equal to the updated received signal strength threshold, then the wireless node of the terminal shall be switched.

[0044] As an example, in step S301, the main gateway can periodically detect the signal strength of the terminal, or only detect the signal strength of the terminal at a specific time point (i.e., non-periodic), thereby obtaining the received signal strength parameters of the terminal at multiple times. The received signal strength parameter is the Received Signal Strength Indicator (RSSI), and the multiple times may include the current time and multiple historical times.

[0045] As an example, in step S302, the main gateway can process the received signal strength parameters detected at multiple times and the preset initial received signal strength threshold to determine the deviation between the received signal strength parameters at multiple times and the preset initial received signal strength threshold, thereby determining the fused received signal strength parameters of the terminal at each time. The fused received signal strength parameters can be used to indicate the deviation between the received signal strength parameters of the terminal and the preset initial received signal strength threshold under the premise of superimposing multiple times.

[0046] Specifically, referring to Figure 4, step S302 may include: S401: Based on the difference between the received signal strength parameter and the preset initial received signal strength threshold, determine the signal strength indication information of the terminal at multiple times; S402: Perform a weighted summation of the signal strength indication information corresponding to each time moment and the time moment preceding each time moment to determine the fused received signal strength parameters for multiple time moments.

[0047] As an example, in step S401, the main gateway can determine the terminal's signal strength indication information at each moment based on the difference between the received signal strength parameter at each moment and the preset initial received signal strength threshold. In other words, the signal strength indication information is the difference between the received signal strength parameter at each moment and the preset initial received signal strength threshold.

[0048] As an example, in step S402, the fused received signal strength parameters can be determined using the following formula: new_DRSSI=α×DRSSI+(1-α)×previous_DRSSI Wherein, new_DRSSI represents the fused received signal strength parameter at a certain moment, α represents the preset weight (i.e., attenuation factor), DRSSI represents the signal strength indication information corresponding to a certain moment, and previous_DRSSI represents the signal strength indication information corresponding to the moment before a certain moment.

[0049] As an example, in step S303, the main gateway can determine the deviation between the terminal's signal reception strength and the preset initial signal reception strength threshold at different times based on multiple fused received signal strength parameters. Then, through clustering processing, it can determine the fused received signal strength parameter located at the cluster center among the fused received signal strength parameters. The fused received signal strength parameter located at the cluster center can be determined as the average deviation between the received signal strength parameters at multiple times and the preset initial received signal strength threshold. Thus, the fused received signal strength parameter located at the cluster center can be combined with the preset initial received signal strength threshold to determine the updated received signal strength threshold of the terminal at the current time.

[0050] For specific details, please refer to Figure 5 Step S303 may include: S501: Perform clustering processing on multiple fused received signal strength parameters to obtain clusters of multiple fused received signal strength parameters; S502: Summing the fused received signal strength parameter located at the center of the cluster and the preset initial received signal strength threshold to determine the updated received signal strength threshold of the terminal at the current moment.

[0051] As an example, in step S501, a clustering algorithm can be used to cluster multiple fused received signal strength parameters to obtain a cluster composed of fused received signal strength parameters. The specific clustering algorithm used in this disclosure is not limited. Any clustering algorithm that can cluster data of the same type into a cluster can be used in this disclosure.

[0052] As an example, since the fused received signal strength parameter located at the cluster center can effectively indicate the parameter characteristics of multiple fused received signal strength parameters, the fused received signal strength parameter located at the cluster center can be summed with the preset initial received signal strength threshold to determine the updated received signal strength threshold of the terminal at the current moment. This can effectively eliminate the influence of short-term fluctuations on the updated received signal strength threshold, further improve the rationality and scientific nature of the updated received signal strength threshold, and realize the dynamic determination of the updated new received signal strength threshold.

[0053] As an example, in step S304, if the received signal strength parameter of the terminal at the current moment is less than or equal to the updated received signal strength threshold, it indicates that the signal quality of the terminal at the current moment is poor. At this time, the main gateway can switch the wireless node corresponding to the terminal to improve the communication quality of the terminal.

[0054] In summary, this example includes: obtaining the received signal strength parameters of the terminal at multiple times, including the current time and multiple historical times; determining the fused received signal strength parameters of the terminal at each time based on a preset initial received signal strength threshold and the received signal strength parameters at each time; determining the updated received signal strength threshold of the terminal at the current time based on multiple fused received signal strength parameters; and switching the terminal's wireless node if the received signal strength parameter of the terminal at the current time is less than or equal to the updated received signal strength threshold. This application determines the fused received signal strength parameters at each time point by utilizing received signal strength parameters at multiple times and a preset initial received signal strength threshold. By combining historical information with current information, it can effectively avoid the situation where the determined updated received signal strength threshold is inaccurate due to signal mutations. Furthermore, by clustering multiple fused received signal strength parameters, the fused received signal strength parameters located at the center of the clusters are summed with the preset initial received signal strength threshold to determine the updated received signal strength threshold of the terminal at the current time. This enables dynamic determination of the updated received signal strength threshold. Moreover, through clustering, the influence of short-term fluctuations on the updated received signal strength threshold can be effectively eliminated, further improving the rationality and scientific nature of the updated received signal strength threshold.
