Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 is to be understood that the terminology used in the embodiments of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

For the understanding of the scheme, the network architecture to which the scheme of the embodiments of the present application is applied will be first described below by way of example with reference to the accompanying drawings. Referring to fig. 1, fig. 1 is a schematic structural diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, a network architecture to which the embodiment of the present application is applied includes a gateway 110, an Access Point (AP)120, and a plurality of stations (stations) 130. The network architecture of the invention is suitable for networking modes such as Wireless Local Area Networks (WLAN), Bluetooth (bluetooth) Wireless personal Area Networks, zigbee networking, Internet of things (IoT) and the like. The Internet of things may be any one of Internet of Vehicles (Internet of Vehicles), Body Area Network (BAN), and M2M (machine-to-machine) Network.

It should be noted that gateway 110 may communicate with access point 120 via a downlink and an uplink. The downlink (or forward link) refers to the communication link from gateway 110 to access point 120, and the uplink (or reverse link) refers to the communication link from access point 120 to gateway 110. The rate when gateway 110 transmits data to access point 120 is an uplink network transmission rate, and the rate when access point 120 transmits data to gateway 110 is a downlink network transmission rate.

An access point may also be referred to as a "hot spot," and the access point may be used to establish a wireless lan and provide access services to a plurality of stations, and is a bridge connecting a wireless network and a wired network. The access point may be an access device dedicated to providing access services, such as a wireless router, or may be a terminal device temporarily providing access services, such as a smart phone, a tablet computer, a notebook computer, or the like capable of providing access services, and the present invention is not limited in particular.

The gateway is connected with a line network which is an upper layer device of the wireless access point 120, the gateway is directly connected with the line network through broadband dialing, and one gateway governs a plurality of wireless access points.

The website may be various terminal devices, for example, a mobile terminal such as a smart phone, a tablet computer, and a notebook computer, a wearable device such as smart glasses, a smart watch, and a smart necklace, a smart home device such as a smart microwave oven, a smart air conditioner, and a smart refrigerator, or an internet of things device such as a smart water meter, a smart electricity meter, and a smart gas meter, which is not limited in the present invention.

It is understood that the actual product names of the access point and the station mentioned in the embodiments of the present application may be different from each other in different vendors, for example, in a bluetooth wireless personal area network, the access point may be referred to as a master device, the station may be referred to as a slave device, and so on, although the change of the product name does not affect the essence of the access point and the station.

It can be understood that, in the prior art, the terminal 130 under the control of the access point 120 can only access the network through the access point 120, and the data uploaded by the terminal 130 under the control of the access point 120 is cached in the access point 120, so that, once the access point 120 fails, the terminal 130 under the control of the access point 120 cannot access the network, and the data uploaded to the access point 120 by the terminal 130 under the control of the access point 120 is lost.

In order to solve the above problem, an embodiment of the present invention provides a method for randomly backing up a wireless access point, and as shown in fig. 2, fig. 2 is a flowchart of the method for randomly backing up a wireless access point, which is provided in the embodiment of the present invention, in which data of a target access point and an internet of things terminal accessing the target access point are respectively migrated to a data backup access point and a terminal backup access point, so that the fault resistance of the target access point is enhanced. The method is described from the perspective of a gateway, and comprises the following steps:

s201: the gateway judges whether the data transmission rate of the target access point is smaller than a preset threshold value.

Specifically, the target access point is any one of the wireless access points governed by the gateway, and the gateway may monitor the data transmission rate of all the wireless access points governed by the gateway regularly, or may monitor the data transmission rate of the wireless access point through the report information of the wireless access point.

In the embodiment of the invention, the data transmission rate is an important index for judging whether a target access point works normally, and when the data transmission rate is at a normal level, the target access point is in a normal working state; when the data transmission rate of the target access point is smaller than a preset threshold value, the target access point is likely to be about to fail. Specifically, for example, when the number of terminals of the internet of things accessed by the target access point is too many, the signal frequency channel used by the target access point is covered by the signal frequency channels of other access points, or the hardware of the target access point is overheated, the data transmission rate of the target access point is significantly reduced.

In the embodiment of the present invention, the preset threshold may be set according to a data transmission rate of the target access point during normal operation, for example, the data transmission rate of the wireless access point during normal operation may reach 10Mbps, and the preset threshold may be set to 10%, that is, 1Mbps, of the data transmission rate of the wireless access point during normal operation, that is, when the gateway detects that the data transmission rate of the wireless access point is less than the preset threshold 1Mbps, it may be determined that the wireless access point has a fault sign.

S202: and if the access point is smaller than the preset threshold value, the gateway randomly selects a data backup access point and a terminal backup access point from the access points to be selected.

S203: and the gateway receives the backup data sent by the target access point and sends the backup data to the data backup access point for backup.

In the embodiment of the present invention, the data backup access point may include the following two cases: (1) the data backup access point may not carry any access service at ordinary times, and only serves as a backup node of the target access point, and when the target access point fails, the backup data is hot backed up to the data backup access point, that is, the data backup access point is only used for backing up the backup data of the target access point. (2) The data backup access point also processes access services of other terminals at ordinary times, and when the target access point fails, the backup data is hot backed up to the data backup access point, namely, the data backup access point simultaneously undertakes backup of the backup data of the target access point and processes the access services of other terminals.

In the embodiment of the present invention, the backup data includes data reported to the target access point by the internet of things terminal under the control of the target access point, and the gateway issues configuration information to the target access point, related information of a channel used by the target access point, and the like. The data reported to the target access point by the internet of things terminal governed by the target access point may include collected external data sent to the target access point by the internet of things terminal, a network request sent to the target access point, and the like.

It is understood that the gateway performs step S203 when the target node is in a normal operating state, that is, the gateway performs a hot backup on the backup data.

S204: and the gateway sends switching information to the target access point, wherein the switching information is used for indicating that the Internet of things terminal governed by the target access point is switched to a terminal backup access point.

In the embodiment of the present invention, the terminal backing up the access point may include the following two cases: (1) the terminal backup access point can not bear any access service at ordinary times and only serves as a backup node of the target access point, and when the target access point fails, the terminal under the control of the target access point is switched to the terminal backup access point, namely, the terminal backup access point is only used for processing the access service of the terminal switched from the target access point. (2) The terminal backup access point also processes the access service of other terminals at ordinary times, and when the target access point fails, the terminal backup access point processes the access service of the terminal switched from the target access point, that is, the data backup access point simultaneously processes the access service of the terminal switched from the target access point and processes the access service of other terminals.

In the embodiment of the present invention, the switching information is used to instruct the terminal of the internet of things under the control of the target access point to switch to the terminal backup access point. In a possible implementation manner, the target access point receives the switching information, and then sends the switching information to the internet of things terminal under the jurisdiction of the target access point, the internet of things terminal passes through the switching information is automatically switched to the terminal backup access point, namely, the internet of things terminal sends the terminal backup access point application corresponding resource and sends self-related state information to the terminal backup access point, the terminal backup access point is that the internet of things terminal distributes resources and carries out authentication according to the state information, and then the internet of things terminal is switched to the terminal backup access point. In another embodiment, the gateway directly disconnects the internet of things terminal from the target access point, connects the internet of things terminal to the terminal backup access point, and switches the internet of things terminal to the terminal backup access point under the unknown condition, so that the operation of the internet of things terminal is avoided, and the power consumption of the internet of things terminal is reduced.

It is understood that the number of the data backup access points may be one or more; likewise, the number of terminal backup access points may be one or more. If the number of the data backup access points and/or the number of the terminal backup access points are multiple, the switching information further comprises the identification of the data backup access points and/or the terminal backup access points. In the embodiment of the present invention, the identifiers of the data backup access point and the terminal backup access point may be Radio Network Temporary Identifiers (RNTI), MAC addresses, or other identifier information that enables the data backup access point and the terminal backup access point to be identified, which is not limited herein.

It should be noted that the gateway is configured to govern the target access point, the data backup access point, and the terminal backup access point, and the data backup access point and the terminal backup access point are different access points. Generally, all wireless access points governed by a gateway form a wireless communication area, for example, an internet of things system of an intelligent parking lot, an intelligent agricultural greenhouse and an intelligent agricultural field respectively has their own wireless communication area, and the wireless communication area includes a plurality of wireless access points, so that management and communication are facilitated.

In order to better understand and implement the above-mentioned solution of the embodiment of the present invention, the following description is made in combination with a specific application scenario, assuming that a bluetooth connection technology is adopted in a wireless network part in the current internet of things, an optical fiber connection is adopted in a wired network part, a network structure diagram of the internet of things is shown in fig. 3-a, an upper management device of a wireless access point is a gateway, the wireless access point and a terminal of the internet of things are wirelessly connected, and the gateway and the wired network are directly connected in a wired manner. The gateway manages three wireless access points, wherein the three wireless access points comprise a target access point A, a data backup access point B and a terminal backup access point C, the target access point A manages the terminals 1, 2 and 3 of the Internet of things, the service data a is cached in the target access point A, the data backup access point B manages the terminals 4 and 5 of the Internet of things, the service data B is cached in the data backup access point B, the terminal backup access point C manages the terminal 6 of the Internet of things, and the service data C is cached in the terminal backup access point C.

Assuming that the data transmission rate of the wireless access point a is less than the preset threshold and a fault occurs, the devices in the internet of things interact by using the method shown in fig. 2, and after the steps in the method shown in fig. 2 are executed, the network structure diagram of the internet of things is shown in fig. 3-B, the service data (i.e., backup data) in the target access point a is backed up in the data backup access point B, and the terminals 1, 2, and 3 of the internet of things governed by the target access point a are connected to the terminal backup access point C.

Referring to fig. 4, fig. 4 is a flowchart of another method for random backup of a wireless access point according to an embodiment of the present invention, where the method is described from the perspective of a gateway. It can be understood that steps S201 to S204 in the method embodiment shown in fig. 2 may also be applied to steps S403 to S406 in this embodiment, which is not described herein again, and the method for randomly backing up a wireless access point in this embodiment includes:

s401: and the gateway detects the uplink network transmission rate and the downlink network transmission rate of the target access point respectively.

Specifically, the uplink network transmission rate is a data transmission rate when the target access point sends information to the gateway, and the downlink network transmission rate is a transmission rate when the gateway sends information to the target access point.

S402: and the gateway determines the data transmission rate between the gateway and the target access point according to the uplink network transmission rate and the downlink network transmission rate.

Specifically, in this embodiment, the uplink network transmission rate and the downlink network transmission rate directly reflect a data transmission rate between the gateway and the target access point, the data transmission rate between the gateway and the target access point can reflect whether the target access point is in a normal working state, and if the data transmission rate between the gateway and the target access point is lower than a preset threshold, the target access point may malfunction.

In other embodiments, the gateway may further determine the data transmission rate between the target access point and the terminal of the internet of things by detecting an uplink network transmission rate and a downlink network transmission rate between the target access point and the terminal of the internet of things under the control of the target access point, respectively.
