Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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.
The network connection method provided by the present invention is further explained with specific embodiments in the following with reference to the drawings, and the embodiments do not limit the embodiments of the present invention.
Referring to fig. 1, a flowchart of an embodiment of a network connection method according to an embodiment of the present invention is provided. As shown in fig. 1, the process may include the following steps:
step 101, detecting a distance between a target terminal currently accessed to a first AP device and the first AP device.
And 102, when the distance is detected to meet the set condition, determining a second AP device closest to the target terminal from the Mesh network.
The following describes steps 101 and 102 collectively:
the execution main body of the embodiment of the present invention may be a first AP device, where the first AP device may be any AP device in a Mesh network. Correspondingly, the target terminal refers to a terminal currently accessed to the first AP device.
In an embodiment, the first AP device may detect a distance between the target terminal and the first AP device in real time, and detect whether the distance satisfies a set condition. Optionally, the setting condition includes that the distance between the target terminal and the first AP device is greater than or equal to a preset distance threshold. Here, the preset distance threshold may be a radius of a network coverage area of the first AP device.
When detecting that the distance between the target terminal and the first AP device satisfies the set condition, it means that the target terminal has moved out of the network coverage area of the first AP device, or is located at the boundary of the network coverage area of the first AP device, at this time, since the target terminal is far away from the first AP device, it is likely that the network connection state is unstable, and the target terminal is not suitable for continuing to access the first AP device.
Based on this, the first AP device determines a second AP device closest to the target terminal from the Mesh network, and specifically, how to determine the second AP device closest to the target terminal is described in detail in fig. 4 below.
And 103, switching the network access point of the target terminal from the first AP equipment to the second AP equipment.
In an embodiment, switching the network access point of the target terminal from the first AP device to the second AP device may be implemented by the flowchart of the embodiment shown in fig. 2. As shown in fig. 2, a flowchart of an embodiment of switching a network access point of a target terminal from a first AP device to a second AP device according to the embodiment of the present invention may include the following steps:
step 201, sending an access request to a second AP device, where the access request carries access information of a target terminal, so that the second AP device accesses the target terminal to the second AP device based on the access information.
Step 202, receiving a response message from the second AP device, where the response message is used to characterize that the target terminal has accessed the second AP device.
And step 203, disconnecting the target terminal from the first AP equipment.
The following describes steps 201 to 203 collectively:
for convenience of understanding, fig. 3 is shown below, which is a schematic diagram of handover of an access point of a target terminal according to an embodiment of the present invention. The above steps 201 to 203 will be described with reference to fig. 3.
In an embodiment, as shown in fig. 3, after a target terminal accesses a first AP device, when the first AP device determines that a network access point of the target terminal is to be switched from the first AP device to a second AP device, the first AP device sends an access request to the second AP device, where the access request carries access information of the target terminal, and the second AP device accesses the target terminal to the second AP device according to the access information of the target terminal carried in the access request.
After that, the second AP device may further send a response message to the first AP device, where the response message is used to characterize that the target terminal has accessed the second AP device. When the first AP device receives the response message from the second AP device, it may determine that the target terminal has accessed the second AP device, and at this time, disconnect the target terminal from the first AP device.
To this end, the first AP device successfully switches the network access point of the target terminal from the first AP device to the second AP device.
In the embodiment of the invention, by detecting the distance between a target terminal which is accessed to a first AP device and the first AP device, when the distance is detected to meet a set condition, a second AP device which is closest to the target terminal is determined from the Mesh network, and a network access point of the target terminal is switched from the first AP device to the second AP device. In the process of switching the network access point of the target terminal, the first AP equipment determines the second AP equipment closest to the target terminal and then directly switches the network access point of the target terminal from the first AP equipment to the second AP equipment, and the process does not involve any operation of the target terminal, so that the network access point of the target terminal is seamlessly switched under the condition of not disconnecting the network connection of the target terminal, the stability of a target terminal network is improved, and the user experience is improved.
In an embodiment, when detecting that any terminal enters a network coverage area of a first AP device, a first AP device (that is, any AP device in a Mesh network) sends a notification message to other AP devices in the Mesh network, where the notification message at least carries device information of any terminal. In this way, when the other AP devices receive the notification message, the device information of the terminal may be analyzed from the notification message, and it is determined that the terminal has currently accessed the first AP device.
On this basis, the flow shown in fig. 4 is shown, and the flow shown in fig. 4 focuses on how to determine the second AP device closest to the target terminal on the basis of the flow shown in fig. 1, and includes the following steps:
step 401, the first AP device detects a distance between a target terminal currently accessed to the first AP device and the first AP device.
Step 401 is described in detail in step 101, and is not described herein again.
Step 402, the first AP device receives a notification message from at least one third AP device.
In an embodiment, the third AP device may be an AP device that the target terminal enters into its network coverage area.
Step 403, when the first AP device detects that the distance satisfies the setting condition, parsing the device information of the target terminal from the received at least one notification message.
Step 404, when the first AP device determines that the target terminal has accessed the first AP device according to the analyzed device information of the target terminal, determining a second AP device closest to the target terminal from at least one third AP device.
The following takes the Mesh network architecture diagram shown in fig. 6 as an example to collectively describe steps 403 and 404:
as shown in fig. 6, an architecture diagram of a Mesh network system provided in an embodiment of the present invention is shown in fig. 6 as an example, and includes: AP device 61, AP device 62, AP device 63, and target terminal 64.
The current access point of the target terminal 64 is the AP device 61 (that is, the AP device 61 is a first AP device, hereinafter referred to as a first AP device 61), the network coverage area of the first AP device 61 is 611, the network coverage area of the AP device 62 is 621, the network coverage area of the AP device 63 is 631, the intersection of the network coverage area 611, the network coverage area 621, and the network coverage area 631 is an area 651.
The target terminal 64 may be a hardware device or software that supports network connectivity to provide various network services. When the target terminal 64 is hardware, it may be a device supporting various electronic devices with a display screen, including but not limited to a smart phone, a tablet computer, a laptop computer, etc., and the smart phone is only used as an example in fig. 6. When the target terminal 64 is software, it can be installed in the electronic devices listed above.
When the target terminal 64 moves to the position point a shown in fig. 6, the position of the point a is in the area 651 and is at the boundary of the first AP device 61, at this time, the AP device 62 and the AP device 63 detect that the target terminal 64 has entered the network coverage area 621 and the network coverage area 631, respectively, and simultaneously send the notification message to the other AP devices, that is, the AP device 62 simultaneously sends the notification message to the first AP device 61 and the AP device 63, and the AP device 63 simultaneously sends the notification message to the AP device 62 and the first AP device 61, that is, both the AP device 62 and the AP device 63 serve as a third AP device to send the notification message to the first AP device 61. The notification message carries at least the device information of the target terminal 64.
Then, the first AP device 61 parses the device information of the target terminal 64 from the received at least one notification message, and determines, according to the device information of the target terminal 64, that the target terminal 64 has accessed the first AP device 61, a second AP device closest to the target terminal 64 from at least one third AP device, that is, a second AP device closest to the target terminal 64 from the AP devices 62 and 63.
Specifically, the notification message also carries the distance between the target terminal 64 and the AP device, that is, the notification message sent by the AP device 62 carries the distance L1 between the AP device 62 and the target terminal 64, and the notification message sent by the AP device 63 carries the distance L2 between the AP device 63 and the target terminal 64. When L1 is smaller than L2, it indicates that the distance between the AP device 62 and the target terminal 64 is closest, and the AP device 62 is regarded as the second AP device.
Optionally, the notification message may also carry the signal strength of the AP device relative to the target terminal 64, that is, the notification message sent by the AP device 62 carries the signal strength Q1 of the AP device 62 relative to the target terminal 64, and the notification message sent by the AP device 63 carries the signal strength Q2 of the AP device 63 relative to the target terminal 64. When Q1 is greater than Q2, since the closer the AP device is to the target terminal 64, the stronger the signal, based on which, the closer the AP device 62 is to the target terminal 64, the AP device 62 is considered as the second AP device. It can be understood that the notification message may also carry other information, and the present invention is not limited thereto.
As an embodiment, when the target terminal 64 enters the location B point shown in fig. 6, which is in the network coverage area 631 of the AP device 63, at this time, the AP device 63 transmits the notification message to the first AP device 61 when detecting that the target terminal 64 enters the area 631. After receiving the notification message, the first AP device 61 directly determines the AP device 63 as the second AP device when determining that the target terminal 64 has accessed the first AP device according to the device information carried in the analyzed notification message.
Step 405, switching the network access point of the target terminal from the first AP device to the second AP device.
Step 405 is described in detail in step 103, and is not described in detail here.
In the embodiment of the present invention, when determining the second AP device closest to the target terminal, and when the target terminal enters the network coverage area of the third AP device, the first AP device receives the notification message from at least one third AP device, and analyzes the device information of the target terminal from the notification message. Determining second AP equipment closest to the target terminal according to the number of third AP equipment after the target terminal is determined to be accessed to the first AP equipment according to the equipment information, and determining the third AP equipment as the second AP equipment closest to the target terminal when the number of the third AP equipment is 1; and when the number of the third AP devices is multiple, determining the third AP device corresponding to the minimum distance in the distances between the target device and the first AP device, which are carried in the notification message sent by the third AP device, as the second AP device closest to the target terminal. When the first AP equipment determines the second AP equipment, the third AP equipment closest to the target terminal is determined as the second AP equipment according to the received notification message of the third AP equipment, so that the stability of the network when the first AP equipment switches the network access point of the target terminal into the second AP equipment is ensured, the stability of the network of the target terminal is improved, and the user experience is improved.
Referring to fig. 5, a flowchart of another embodiment of a network connection method according to an embodiment of the present invention is provided. As shown in fig. 5, the process may include the following steps:
step 501, detecting the number of terminals currently accessed to the first AP device.
Step 502, when it is detected that the number of the terminals is greater than or equal to a preset number threshold, sending an alarm message to a Mesh router in the Mesh network, so that the Mesh router reallocates channels to a subnet where the plurality of AP devices are located after receiving the alarm message from the plurality of AP devices.
Step 501 and step 502 are explained below in a unified manner:
in an embodiment, as shown in fig. 7, a Mesh network structure includes multiple subnets, each subnet includes multiple AP devices, and each AP device has access to a different number of terminals. In order to avoid network congestion caused when a large number of terminals access the AP device, the first AP device may periodically detect the number of terminals currently accessing the first AP device. When detecting that the number of the terminals is greater than or equal to the preset number threshold, the first AP device may send an alarm message to a Mesh router in the Mesh network, so that the Mesh router receives the alarm message from the multiple AP devices and reallocates a channel for a subnet where the multiple AP devices are located. It should be noted that the preset number threshold may be 50 or 100, and the present invention is not limited to this.
In the embodiment of the invention, the number of terminals which are currently accessed to the first AP equipment is detected by the first AP equipment, and when the number of the terminals is detected to be larger than or equal to the preset number threshold, the first AP equipment sends the alarm message to the Mesh router in the Mesh network, so that the Mesh router receives the alarm messages from the plurality of AP equipment and then reallocates channels for the subnets where the plurality of AP equipment are located. By detecting the number of currently accessed terminals and sending out warning messages when the number of the terminals exceeds a preset number threshold, network congestion caused when a large number of terminals are accessed into the AP equipment is avoided, and therefore the stability of a target terminal network is improved, and user experience is improved.
