All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
In a preferred embodiment of the present invention, based on the above problems in the prior art, a networking system of a wireless local area network is provided, as shown in fig. 1, the networking system includes a plurality of access devices, the plurality of access devices includes a plurality of root node devices 1 and a plurality of child node devices 2, each root node device 1 is respectively provided with a 5G communication module 11, and can communicate with an external 5G base station 3 through the 5G communication module 11.
Then, as shown in fig. 2, each root node device 1 includes:
the first detection unit 12 is configured to send a detection request frame on each channel in a first preset period after the root node device is powered on and started, and obtain a monitoring result of the detection request frame;
the first access unit 13 is connected to the first detection unit 12, and configured to add the node network to the node network according to the network service set identifier when the monitoring result indicates that there is an available network service set identifier in a first preset period;
the creating unit 14 is connected to the first detecting unit 12, and configured to create an available network service set identifier and join the available network service set identifier into a corresponding node network when the monitoring result indicates that the available network service set identifier does not exist in the first preset period;
a first connection unit 15 for accessing an external wireless client device 4;
after joining the node network, the root node device 1 performs data communication with the 5G base station 3 through the 5G communication module 11.
As shown in fig. 3, each child node device 2 includes:
the second detection unit 21 is configured to send a detection request frame on each channel in a second preset period after the child node device is powered on and started, and obtain a monitoring result of the detection request frame;
the second access unit 22 is connected to the second detection unit 21, and configured to add the node network to the node network according to the network service set identifier when the monitoring result indicates that there is an available network service set identifier in a second preset period;
the second detecting unit 21 is further configured to, when the monitoring result indicates that there is no available network service set identifier monitored in the second preset period, sleep and then continue to send a detection request frame on each channel in the second preset period;
a second connection unit 23 for accessing an external wireless client device 4;
after the child node device 2 joins the node network, data communication is performed with the 5G base station 3 through at least one root node device 1 in the same node network.
Specifically, the network service Set identifier (ssid) in the prior art is widely provided for devices to discover the established wlan. The wireless network that has been created can also be discovered based on the SSID in this embodiment.
In this embodiment, the access device is first divided into the root node device 1 and the child node device 2, and only the root node device 1 is allowed to create the node network, and the child node device 2 is only allowed to join the node network, and is not allowed to create the node network.
The triggering condition for each root node device 1 to create the node network is that it cannot detect the node network which exists and can join after power-on, that is, the first detection unit 12 is adopted to send the detection request frame on each channel within a first preset time period, and monitor whether feedback information related to the detection request frame exists. If the feedback can be monitored, it indicates that at least a node network capable of joining exists on a certain channel, and at this time, the root node device 1 does not need to create a node network by itself, but only needs to access the node network created by other root node devices 1. Of course, if the root node device 1 is disconnected due to some failure reasons (for example, the node network that has already joined is disconnected due to a failure), the root node device 1 may resend the probe request frame and retry to join the existing node network.
Further, if a certain root node device 1 does not monitor the feedback information of the probe request frame within the first time period, it is determined that no node network capable of joining exists on the channel available to the root node device 1 at present, and at this time, the root node device 1 may create a node network by itself and wait for other root node devices 1/child node devices 2 to join.
Accordingly, each child node device 2 has no function of creating a node network by itself, and therefore can only select to join a certain node network that has already been created. Specifically, after each child node device 2 is powered on, it first sends a probe request frame in a second preset period, and similarly checks whether there is a corresponding monitoring result. If yes, accessing to a corresponding node network; if not, the child node device 2 sleeps for a period of time and then sends the probe request frame again until finding and joining the corresponding node network.
In addition, in order to prevent the child node device 2 from falling into an endless loop at the stage of inquiring the node network, an upper limit of the number of times of repeatedly attempting to transmit the probe request frame may be set in advance. When the number of times that the child node device 2 attempts to repeatedly send the probe request frame reaches the preset upper limit of times, the child node device 2 outputs a prompt that the network cannot be connected, and exits from the sending process of the probe request frame, and then stands by or is shut down to wait for the user to check.
In this embodiment, the first preset period may be set to 120s or another suitable time period, that is, the first detecting unit 12 sends the probe request frame in the time period of 120s and continuously monitors the feedback result of the probe request frame, so as to obtain the corresponding monitoring result.
And
the second preset period may be set to 30s or another suitable time period, that is, the second detection unit 21 sends the detection request frame in the time period of 30s and continues to monitor the feedback result of the detection request frame, so as to obtain the corresponding monitoring result.
Specifically, after the root node device 1 is powered on, the first probing unit 12 sends a probing request within 120s, and if there is an available network service set SSID in the network, joins the node network; if no available network service set SSID is detected, the connection creation unit 14 creates an SSID and responds to probe requests of other root node devices 1 or child node devices 2.
And
after the child node device 2 is powered on, the second detection unit 21 sends a detection request within 30s, and if the network has an available network service set SSID, the node device joins the node network; if no available network service set SSID is detected, the system sleeps for a period of time before sending the probe request frame. And the cycle is repeated until the available network service set SSID is detected, or the sub-node device 2 fails, or the sending times of the sent detection request frames reach the upper limit.
In this embodiment, the sleep duration of the detecting unit 21 may be set to 30s or other suitable time period, that is, when the second detecting unit 21 does not respond to the detection request, the second detecting unit continues to send the detection request frame and continuously monitors the feedback result of the detection request frame after sleeping for 30s, and obtains the corresponding monitoring result.
Specifically, after the sub-node device 2 is powered on, the second probe unit 21 sends the probe request in the second time period, and if no response of the available network service set SSID is received in the network, the probe request frame is sent every 30 s. If no available network service set SSID has been detected yet, probe request frames continue to be sent every 30 s. And the cycle is repeated until the available network service set SSID is detected, or the sub-node device 2 fails, or the sending times of the sent detection request frames reach the upper limit.
In this embodiment, the first connection unit 14 of the root node device 1 and the second connection unit 23 of the child node device 2 are connected to an external wireless client device by a way of embedding a 2.4G radio frequency chip and/or a 5G radio frequency chip, so as to provide a data transmission service of a wireless network for the wireless client.
In this embodiment, although there is only one "creator" for a node network, that is, the root node device 2 that creates the SSID corresponding to the node network, there may be a plurality of root node devices 2 in a node network, including the root node device 2 that creates the SSID and the root node devices 2 that subsequently join in the node network. Therefore, there may be a plurality of access devices performing a network management function for the node network, i.e., all root node devices 2 in the node network.
It should be noted that, the connection relationship between the devices is simplified in fig. 1, and actually, the child node devices 2 located in the same node network may communicate with each other, the child node device 2 and the root node device 1 may communicate with each other, and the root node device 1 may also communicate with each other. In addition, each root node device 1 and each child node device 2 can access the wireless client device 4, which is not described herein again.
In a preferred embodiment of the present invention, as shown in fig. 2, in the networking system, each root node device 1 further includes:
and the third access unit 16, configured to connect to the creating unit 15, and configured to continuously monitor a probe request frame in a network channel corresponding to the node network and feed back corresponding response information after the root node device 1 creates an available network service set identifier by itself and joins the node network, so as to join the root node device and/or the child node device into the node network.
Specifically, in this embodiment, after the root node device 1 needs to create an available SSID by itself and join the corresponding node network, the third access unit 16 may continuously monitor probe request frames of other access devices after creating and joining the node network, and allow the access device to access the node network by feeding back the probe request frames.
In a preferred embodiment of the present invention, when the monitoring result indicates that there are a plurality of available network service set identifiers monitored in the first preset period, the first access unit 13 selects one of the network service set identifiers according to the quality of the network signal and adds the selected network service set identifier to the corresponding node network;
and
when the monitoring result indicates that a plurality of available network service set identifiers exist in the second preset period, the second access unit 22 selects one of the network service set identifiers according to the network signal quality and adds the selected network service set identifier to the corresponding node network.
Specifically, in this embodiment, when the monitoring result indicates that only one SSID is currently available, the access device may directly access the node network corresponding to the SSID. When the monitoring result indicates that a plurality of SSIDs are currently available, the problem of selecting which SSID to access is involved. The selection logic is the same for the root node device 1 and the child node devices 2, i.e. it can be determined by the quality of the network signal detected on each SSID which node network corresponds to which SSID is accessed. The network signal quality may be evaluated by using common signal reference values such as RSSI, RSRP, RSRQ, or SNR, or obtained by performing comprehensive evaluation according to the common signal reference values, which is not described herein again.
In a preferred embodiment of the present invention, in the networking system, each access device further includes:
the monitoring unit is used for continuously monitoring whether the access equipment sending the response information has faults or not and outputting a corresponding monitoring result;
when the monitoring result indicates that the access device sending the response information fails, the access device retransmits the probe request frame and retries to join the node network.
Specifically, in this embodiment, as shown in fig. 2, the root node device 1 includes a monitoring unit 17, configured to continuously monitor whether the root node device 1 that sends the response information fails, and output a corresponding monitoring result; when the monitoring result indicates that the root node apparatus 1 which has sent the response information has failed, the root node apparatus 1 retransmits the probe request frame by its probe request unit 12 and retries joining the node network.
In particular, if a root node device 1 is in the role of creating a node network, rather than in the role of joining a node network, the monitoring unit 17 in the root node device 1 is not functional while in the node network.
As shown in fig. 3, the child node device 2 further includes a monitoring unit 24, configured to continuously monitor whether the child node device 2 that sends the response information fails, and output a corresponding monitoring result; when the monitoring result indicates that the child node device 2 that has sent the response information has failed, the child node device 2 retransmits the probe request frame by its probe request unit 21 and retries to join the node network.
In a preferred embodiment of the present invention, in the networking system, each root node device 1 can communicate with external 5G base stations 3 belonging to different operators through a 5G communication module 11;
deploying a plurality of root node devices at each deployment position point in advance respectively;
each root node device 1 includes a signal measurement unit (not shown in the figure) for measuring and outputting signal strength values of different 5G base stations;
the networking system further includes a signal deployment device (not shown in the figure), which is respectively connected to each root node device 1, and configured to synthesize signal strength values output by all the root node devices at the deployment location points for each deployment location point, and select a corresponding 5G base station of an operator as the 5G base station associated with the deployment location point.
Specifically, in this embodiment, different root node devices 1 may be deployed at different geographical locations in advance, and then the deployed root node devices 1 may receive signals from different base stations of different operators, and at this time, the signal measurement unit in each root node device 1 may be respectively adopted to measure and output the signal strength values of the 5G base stations connected to different operators on each root node device 1. The signal strength value may be represented by an absolute value of RSSI, and will not be described herein.
In this embodiment, in the process of deploying the root node device 1 in advance, a plurality of root node devices 1 may be deployed at the same deployment point, and the selection logic of the 5G base station of the deployment point is as follows:
the signal deployment equipment is used for comprehensively calculating the signal strength values of all the root node equipment 1 positioned at the same deployment point (or within a certain range near the deployment point), and selecting a corresponding 5G base station of an operator as a 5G base station of the deployment point (or within a certain range near the deployment point) and designated for connection according to the calculation result.
The above-mentioned comprehensive calculation method may be:
the signal strength values of the 5G base stations corresponding to different operators collected from all the root node devices 1 are averaged to calculate an average signal level of the signal strength values of the 5G base stations of each operator, and then the 5G base station with the highest average signal level is selected as the 5G base station of the deployment point (or within a certain range near the deployment point) which is designated to be connected.
In the preferred embodiment of the present invention, as still shown in fig. 3, in the networking system, each child node device 2 further includes:
an acquisition unit 24 configured to periodically acquire resource usage data of each root node device when a plurality of root node devices exist in the node network;
the load balancing unit 25 is connected with the acquisition unit 24 and is used for respectively processing the resource use data to obtain load balancing performance values of each root node device;
and a selecting unit 26, connected to the load balancing unit 25, for selecting at least one root node device 1 according to the load balancing performance value, and performing data communication with the external 5G base station 3 through the selected root node device 1.
Specifically, in this embodiment, the acquiring unit 24 acquires resource usage data of all root node devices 1 in the node network, where the resource usage data includes a CPU utilization (cur _ p1), a packet loss rate (cur _ p2), a throughput (cur _ p3), and a base station signal strength value (cur _ p4) of the root node device 1.
The load balancing unit 25 sets the Threshold values of the root node device, including the CPU utilization Threshold (Threshold _ p1), the packet loss Threshold (Threshold _ p2), the throughput Threshold (Threshold _ p3), and the base station signal strength Threshold (Threshold _ p4) of the root node device 1. The load balancing unit 25 is configured to obtain a load balancing performance value of each root node device by processing according to the resource usage data of each root node device 1.
Specifically, the way of processing to obtain the load balancing performance value of the root node device 1 includes: firstly, according to the resource usage data and the threshold corresponding to each resource usage data, a load difference Δ p1 (corresponding to the CPU utilization rate), Δ p2 (corresponding to the packet loss rate), Δ p3 (corresponding to the throughput), and Δ p4 (corresponding to the base station signal strength value) of each resource usage data are calculated. Wherein, the Δ p1, the Δ p2 and the Δ p3 are all the set threshold value minus the acquired value, and the Δ p4 is the acquired value minus the set threshold value. Then, the above load difference values are calculated to obtain a comprehensive load balancing performance value of the root node device 1.
Furthermore, the resource use data comprises a plurality of sub-data of different types, and a weight value is set in advance according to each sub-data;
the load balancing unit 25 obtains the load balancing performance value of each root node device according to the following formula:
P(Ri)＝w_p1*Δp1+w_p2*Δp2+......+w_pn*Δpn；
wherein the content of the first and second substances,
p (ri) is used to represent load balancing performance values;
w _ pn (n is more than or equal to 1 and n is a natural number) is used for representing the weight value corresponding to each seed data;
Δ pn is used to represent the difference between the actual acquisition value of each seed data from the corresponding and pre-set threshold (i.e., the load difference described above).
In this embodiment, the selecting unit 26 selects the root node device 1 with the smallest load balancing performance value as a channel for communicating with the external 5G base station 3 according to the load balancing performance value of each root node device 1 in the node network in which the corresponding child node device 2 is located.
In addition, the child node device 25 may also provide a comprehensive load performance table of all the relevant root node devices 1 according to the above calculation result.
When the child node device 2 performs data forwarding for the wireless client device, the selection unit 26 selects the root node device 1 with the largest load balancing performance value to perform data forwarding upwards according to the comprehensive load performance table of the root node device 1 provided by the load balancing unit 25.
