Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication load balancing, and particularly relates to a multi-band load balancing method and device, network equipment and a computer program product. BACKGROUND

[0002] With the vigorous development of Internet of Things technology, there is a general demand for multi-STA (Station) access in users' homes. In this scenario, a single AP needs to handle network connection and data transmission of multiple devices at the same time, which puts extremely high requirements on the performance and stability of the AP. Under the traditional WLAN management mode, a single AP cannot implement load balancing strategy, which leads to the situation that some frequency bands may be overloaded at some moments, while other frequency bands may be in an idle state, which undoubtedly reduces the overall efficiency of the network and user experience. Therefore, on the basis of cost saving, how to implement a dual-frequency load balancing strategy in a single AP to meet the growing network needs of users has become an important problem to be solved in the current WLAN technical field. By introducing the intra-band load balancing technology, we can more intelligently allocate network resources, improve the stability and throughput of the network, and provide better network services for users.

[0054] The embodiments of the present application provide a multi-band load balancing method for realizing load balancing of multiple target frequency bands of a target AP (Wireless Access Point, wireless network access point), improving the communication performance and communication quality of the target AP. The multi-band load balancing method provided by the present application, by respectively acquiring the total flow of each target frequency band in the multiple target frequency bands of the target AP; then acquiring the total flow and average flow of all clients connected on the first target frequency band in the multiple target frequency bands; completing the load balancing of the first target frequency band based on the total flow and average flow of all clients connected on the first target frequency band; acquiring the total flow and average flow of all clients connected on the second target frequency band in the multiple target frequency bands; completing the load balancing of the second target frequency band based on the total flow and average flow of all clients connected on the second target frequency band, realizing the load balancing of the multiple frequency bands of the target AP, improving the communication performance and communication quality of the target AP.

[0055] The multi-band load balancing method provided by the embodiments of the present application can be applied to network devices such as routers with APs, mobile phones, tablet computers, vehicle-mounted devices, notebook computers, ultra-mobile personal computers (UMPC), and the like. The embodiments of the present application do not limit the specific type of network devices.

[0056] As shown in Figure 1 The embodiments of the present application provide a multi-band load balancing method, which includes the following steps:

[0057] In step S11, the total flow of each target frequency band in the plurality of target frequency bands of the target AP is obtained respectively.

[0058] In application, the target frequency bands include 2G, 5G and 6G. The total flow of the target frequency band is the actual bandwidth of the communication interface of the target frequency band, which is smaller than the maximum supported bandwidth of the communication interface of the target frequency band and is determined by the actual environment.

[0059] In step S12, the total flow and the average flow of all clients connected on the first target frequency band in the plurality of target frequency bands are obtained.

[0060] In step S13, the load balancing of the first target frequency band is completed based on the total flow and the average flow of all clients connected on the first target frequency band.

[0061] In application, the total flow and the average flow of all clients connected on the first target frequency band meet the preset load balancing condition of the first target frequency band, and the load balancing is performed; otherwise, the existing communication connection state is maintained.

[0062] In step S14, the total flow and the average flow of all clients connected on the second target frequency band in the plurality of target frequency bands are obtained.

[0063] In application, after the load balancing of the first target frequency band is completed, the total flow and the average flow of all clients connected on the second target frequency band are obtained, so that the latest total flow and average flow of all clients connected on the second target frequency band are obtained along with the load balancing of the first target frequency band.

[0064] In step S15, the load balancing of the second target frequency band is completed based on the total flow and the average flow of all clients connected on the second target frequency band.

[0065] In the application, the total traffic and the average traffic of all clients connected on the second target frequency band meet the preset load balancing condition of the second target frequency band, and the load balancing is performed; in the case that the total traffic and the average traffic of all clients connected on the first target frequency band do not meet the preset load balancing condition of the first target frequency band, the existing communication connection state is maintained.

[0066] In the application, the target frequency band includes 2G, 5G and 6G, the first target frequency band is 5G, and the second target frequency band is 2G. According to different use scenarios, the first target frequency band and the second target frequency band can be configured. For example, in an indoor scenario (such as a bedroom or a living room), the first target frequency band is set to 5G, and the second target frequency band is set to 2G; in an outdoor scenario, the first target frequency band is set to 2G, and the second target frequency band is set to 5G.

[0067] In one embodiment, the step S13, based on the total traffic and the average traffic of all clients connected on the first target frequency band, completes the load balancing of the first target frequency band, comprising:

[0068] Step S131, in the case that the total traffic of the first target frequency band minus the total traffic of all clients connected on the first target frequency band is greater than the preset traffic threshold of the first target frequency band, the average traffic of all clients connected on the first target frequency band is calculated.

[0069] In the application, the total traffic of the first target frequency band minus the total traffic of all clients connected on the first target frequency band is greater than the preset traffic threshold of the first target frequency band, and the load balancing of the first target frequency band is triggered. The average traffic of all clients connected on the first target frequency band = the total traffic of all clients connected on the first target frequency band ÷ the number of all clients connected on the first target frequency band; the total traffic of all clients connected on the first target frequency band is obtained by adding the traffic of each client connected on the target frequency band.

[0070] Step S132, for each target client in all clients connected on the first target frequency band, if the traffic of the target client is greater than the average traffic of all clients connected on the first target frequency band, the connection frequency band of the target client is switched to the second target frequency band of the target AP.

[0071] In the application, the traffic of the target client is greater than the average traffic of all clients connected on the first target frequency band, which means that the load of the target client on the first target frequency band is greater than the average level of the load of all clients on the first target frequency band.

[0072] In an application, for each target client in all clients connected on the first target frequency band, if the traffic of the target client is in the top pre-set number (e.g. top three) of all clients connected on the first target frequency band, the connection frequency band of the target client is switched to the second target frequency band of the target AP.

[0073] In an application, the connection frequency band of the target client is switched to the second target frequency band of the target AP according to the communication protocol (802.11k / v / r protocol) supported by the target client device, and the priority is 802.11v>802.11r>802.11k when all the three protocols are supported.

[0074] In an embodiment, the step S15, the load balancing of the second target frequency band is completed based on the total traffic and the average traffic of all clients connected on the second target frequency band, including:

[0075] Step S151, in the case that the total traffic of the second target frequency band minus the total traffic of all clients connected on the second target frequency band is greater than the pre-set traffic threshold of the second target frequency band, the average value of the traffic of all clients connected on the second target frequency band is calculated.

[0076] In an application, the total traffic of the second target frequency band minus the total traffic of all clients connected on the second target frequency band is greater than the pre-set traffic threshold of the second target frequency band, and the load balancing of the second target frequency band is triggered. The average value of the traffic of all clients connected on the second target frequency band = the total traffic of all clients connected on the second target frequency band ÷ the number of all clients connected on the second target frequency band; the total traffic of all clients connected on the second target frequency band is obtained by adding the traffic of each client in all clients connected on the second target frequency band.

[0077] Step S152, for each target multi-frequency client in all clients connected on the second target frequency band, if the traffic of the target multi-frequency client is greater than the average value of the traffic of all clients connected on the second target frequency band, the connection frequency band of the target multi-frequency client is switched to the first target frequency band of the target AP. In an application, if the traffic of the target client is greater than the average value of the traffic of all clients connected on the second target frequency band, it means that the load brought by the target client to the second target frequency band is greater than the average level of the load brought by all clients on the second target frequency band to the second target frequency band.

[0078] In an application, for each target client in all clients connected on the second target frequency band, if the traffic of the target client is in the top pre-set number (e.g. top three) of all clients connected on the second target frequency band, the connection frequency band of the target client is switched to the second target frequency band of the target AP.

[0079] In an embodiment, the method further comprises:

[0080] Step S161, different load priorities are assigned to clients connected to the AP.

[0081] Step S162, if the load priority of the client is higher than a pre-set priority, the frequency band switching operation of the client in the load balancing process is cancelled.

[0082] In an application, different load priorities of clients on target frequency bands are assigned to clients according to the communication requirements of the clients, and the communication requirements include communication rate priority and communication distance priority. For example, in the case that the first target frequency band is 5G and the second target frequency band is 2G, the communication type of a television is communication rate priority, and the communication type of a robot is communication distance priority. The load priority of the television on the first target frequency band > the first pre-set priority of the first target frequency band > the load priority of the robot on the first target frequency band; the load priority of the robot on the first target frequency band > the first pre-set priority of the first target frequency band > the load priority of the television on the first target frequency band.

[0083] As shown in FIG. 1, Figure 2 In an embodiment, the method further comprises:

[0084] Step S171, a connection request of a terminal device is detected, and the connection request includes a target AP requested to be connected by the terminal device and frequency band support information of the terminal device.

[0085] In an application, when a terminal device connects to a target AP for the first time, a connection request is sent.

[0086] Step S172, if the connection request of the terminal device is detected and the frequency band support information of the terminal device includes the first target frequency band and the second target frequency band, the number of all clients connected on the target AP is obtained.

[0087] In an application, a device such as a mobile phone or a computer supports multiple frequency bands.

[0088] Step S173, if the number of all clients connected on the target AP is less than a total client threshold of the target AP, the number of all clients connected on the first target frequency band of the target AP is obtained.

[0089] In application, the total client threshold of the target AP is the maximum number of clients supported by the target AP to connect, which is the sum of the maximum number of clients supported by each target frequency band in the target AP to connect. If the number of all clients connected on the target AP is not less than the total client threshold of the target AP, it means that the target AP no longer supports access to new devices.

[0090] In step S174, if the number of all clients connected on the first target frequency band is less than the first client threshold of the first target frequency band, the terminal device is connected to the first target frequency band as a client.

[0091] In step S175, if the number of all clients connected on the first target frequency band is not less than the first client threshold of the first target frequency band, the number of all clients connected on the second target frequency band of the target AP is obtained.

[0092] In step S176, if the number of all clients connected on the second target frequency band is less than the second client threshold of the second target frequency band, the terminal device is connected to the second target frequency band as a client.

[0093] In application, the terminal device initially connected to the target AP is preferentially connected to the first target frequency band of the target AP. When the number of clients connected on the first target frequency band reaches the first client threshold, the terminal device is connected to the second target frequency band.

[0094] In one embodiment, the method further comprises:

[0095] In step S181, in the case that the connection request of the terminal device is detected and the frequency band support information of the terminal device only includes the second target frequency band, the number of all clients connected on the second target frequency band is obtained.

[0096] In application, some older models of terminal devices only support one target frequency band, for example, only support the second target frequency band, and therefore need to be connected to the second target frequency band.

[0097] In step S182, if the number of all clients connected on the second target frequency band is less than the second client threshold of the second target frequency band, the terminal device is connected to the second target frequency band as a client.

[0098] In step S183, if the number of all clients connected on the second target frequency band is not less than the second client threshold of the second target frequency band, a connectable AP is selected for the terminal device based on inter-AP load balancing.

[0099] In the application, for a terminal device only supporting the second target frequency band, if the number of clients connected to the target AP on the second target frequency band of the target AP reaches the second client threshold, the AP with the minimum load in the other APs and the minimum load on the second target frequency band can be selected as the connectable AP for the terminal device.

[0100] In one embodiment, the method further comprises:

[0101] In step S191, if the number of all clients connected to the target AP is not less than the total client threshold of the target AP, a substitute AP is selected for the terminal device based on inter-AP load balancing.

[0102] In the application, if the number of all clients connected to the target AP reaches the total client threshold of the target AP, it means that all target frequency bands of the target AP have reached the maximum number of supported connected clients, and the AP with the minimum load in the other APs is selected as the substitute AP for the terminal device.

[0103] In step S192, based on the frequency band support information of the terminal device, the terminal device is accessed to the optimal target frequency band in the multiple target frequency bands of the substitute AP as a client.

[0104] In the application, based on the frequency band support information of the terminal device, the terminal device is accessed to the optimal target frequency band in the multiple target frequency bands of the substitute AP as a client, which can be performed according to the steps S11 to S15.

[0105] It should be understood that the size of the serial number of each step in the above embodiments does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
