Description

WiFi hotspot type identification method and device and storage medium

Technical Field

The present disclosure relates to wireless communication technologies, and in particular, to a method, a device, and a storage medium for identifying a WiFi hotspot type.

Background

When a user uses a terminal, the network service is often used by connecting to a WiFi hotspot. WiFi hotspots can be divided into mobile hotspots and fixed hotspots. The mobile hotspot is a WiFi hotspot with a mobile terminal as a WiFi Access Point (AP), for example, a WiFi hotspot set by a smart phone or a tablet; a fixed hotspot is a WiFi hotspot that is set by the home/corporate gateway as a WiFi AP, e.g., by a home router. In many scenarios, the terminal may perform different operations depending on the type of WiFi hotspot connected. For example, when the terminal executes the positioning function, whether positioning needs to be started or not is determined according to the type of the connected WiFi hotspot, and if the WiFi hotspot is judged to be a mobile hotspot, the positioning function is triggered to acquire current position information; if the WiFi hotspot is judged to be the fixed hotspot, the position information acquired by positioning when the WiFi hotspot is connected for the first time is directly used without restarting positioning, so that the power consumption is reduced.

In the prior art, a mode for a terminal to determine a WiFi hotspot type is that the terminal analyzes an Option field in a DCHP message sent by a WiFi AP after WiFi connection is established. If the WiFi AP adopts the Android system, an Option field in the DCHP message sent by the WiFi AP will include Android information. Therefore, if the android information is contained in the analysis Option field of the terminal, the WiFi hotspot is judged to be a mobile hotspot; and if the Option field does not contain android information, judging the WiFi hotspot to be a fixed hotspot.

However, when the method is adopted, the mobile terminal adopting other systems except the Android system can be judged as a fixed hotspot because the Option field in the DCHP message sent by the mobile terminal does not contain Android information; and the home gateway adopting the Android system judges the home gateway as a mobile hotspot because the Option field in the DCHP message sent by the home gateway contains Android information. Therefore, this method is very likely to cause a judgment error.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all 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 application.

Wireless access via WiFi hotspots has become a standard way for many terminals to surf the internet, for example, as shown in fig. 1, a plurality of WiFi stations (stations) access the network via a WiFi AP. The WiFi AP can be a mobile terminal such as a smart phone and a smart tablet, and the WiFi hotspot is a mobile hotspot; the WiFi AP may also be a home/corporate gateway, for example, a home wireless router, and its WiFi hotspot is a fixed hotspot. The WiFi Station may be any device that can be connected to the WiFi AP in the wireless network, such as a terminal, such as a notebook computer, a mobile phone, and a PDA, which is not limited in this embodiment. In many application scenarios, the WiFi Station may identify the type of the WiFi hotspot, and then may perform different operations according to the identified type of the WiFi hotspot. In the present application, a specific application scenario of the WiFi hotspot type identification is not limited, and is described as an example below.

For example, in one scenario, the positioning function of the terminal is one of its important functions, and the power consumption of the positioning function used by the terminal is usually large, so it is generally desirable to reduce the positioning frequency as much as possible while ensuring the normal use of the positioning function, so as to achieve the purpose of reducing the power consumption. In order to achieve the above purpose, when the terminal performs the positioning function, it is determined whether to initiate positioning according to the type of the connected WiFi hotspot. If the terminal judges that the WiFi hotspot is a mobile hotspot, a positioning function is triggered to acquire current position information; if the WiFi hotspot is judged to be a fixed hotspot, the position of the WiFi hotspot in the current time period is determined to be relatively fixed, so that the position information acquired by positioning when the WiFi hotspot is connected for the first time is directly used, and the positioning is not required to be started again, so that the power consumption is reduced.

For example, in another scenario, a user views or downloads a video using a terminal that determines whether to continue playing or downloading based on the type of WiFi hotspot connected. If the terminal judges that the WiFi hotspot is a fixed hotspot, the terminal continues to play or download the video; if the terminal judges that the WiFi hotspot is a mobile hotspot, playing or downloading the video is paused, or prompt information is output to remind a user that the mobile hotspot is currently used, so that the phenomenon that the network traffic of the mobile hotspot is excessively consumed is avoided.

As can be seen from the above statements, how the WiFi Station correctly determines the type of the WiFi hotspot is very important. In the prior art, the WiFi Station determines the WiFi hotspot type by analyzing an Option field in a DCHP message sent by a WiFi AP after the WiFi connection is established. If the WiFi AP adopts the Android system, an Option field in the DCHP message sent by the WiFi AP will include Android information. Therefore, if the WiFi Station analysis Option field contains android information, the WiFi hotspot is judged to be a mobile hotspot; and if the Option field does not contain android information, judging the WiFi hotspot to be a fixed hotspot.

However, in the above method, when a mobile terminal of a system other than the Android system is used as the WiFi AP, since the Option field in the DCHP message sent by the mobile terminal does not include Android information, the mobile terminal is determined to be a fixed hotspot; and the WiFi hotspot set by the home gateway adopting the Android system is judged as a mobile hotspot because the Option field in the DCHP message sent by the WiFi hotspot contains Android information. Therefore, this method is very likely to cause a judgment error.

In addition, there is a problem in that the type of the WiFi hotspot can be identified only after the WiFi Station has established a connection with the WiFi AP, and if the connection between the WiFi Station and the WiFi AP has not been established, the WiFi Station cannot identify the type of the WiFi hotspot.

In order to solve the above problem, the present application proposes that the type identifier is carried in a message broadcasted by the WiFi AP to the WiFi Station, and the type identifier may be preconfigured according to a product type of the WiFi AP. Therefore, the WiFi Station can accurately identify the type of the WIFI hotspot according to the received broadcast message sent by the WiFi AP.

The method for identifying the type of the WiFi hotspot provided by the present application is described in detail below with reference to specific embodiments. It is to be understood that the following detailed description may be combined with certain embodiments, and that the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic flowchart of a WiFi hotspot type identification method provided in the present application. As shown in fig. 2, the method includes:

s201, the WiFi AP generates a broadcast message.

The broadcast message comprises a type identifier of the WiFi hotspot, wherein the type identifier is used for indicating that the type of the WiFi hotspot is a mobile hotspot or a fixed hotspot.

The broadcast message in this embodiment may be a Beacon (Beacon) message, or may also be a broadcast message newly defined between the WiFi AP and the WiFi Station, which is not limited in this embodiment. Taking the broadcast message as the Beacon message as an example, the Beacon message usually includes basic public information of the WiFi hotspot, such as a Media Access Control Address (MAC Address), a hotspot name, a Beacon message broadcast period, and the like, so that the WiFi Station can periodically receive the broadcast message to perform relevant information analysis and perform relevant processing at a service level. In order to solve the problem of identifying the hotspot type, a field is added in the Beacon message as a type identification field of the WiFi hotspot, that is, the field is used to mark the WiFi hotspot as a mobile hotspot or a fixed hotspot. Illustratively, an AP FIX field is added to the Beacon message, where 1 indicates a fixed hotspot and 2 indicates a mobile hotspot.

It should be understood that the foregoing only takes the broadcast message as the Beacon message, and the Beacon message is exemplified by adding an AP FIX field. In practical applications, the added fields and the type and meaning of the fields may be set as desired. In addition, the broadcast message may also be a broadcast message newly defined outside the existing broadcast message, and a field in the broadcast message is used as the type identification field of the WiFi hotspot.

The type identification field in the broadcast message can be driven by a chip of the WiFi AP to provide an external configuration interface, so that a product manufacturer of the WiFi AP can configure according to the product form during production. For example, when a home router is produced, a type identifier 1 is set in a WIFI chip of the home router, which indicates a fixed hotspot; when the smart phone is produced, a type identifier 2 is set in a WIFI chip module of the smart phone, and a mobile hotspot is represented. And when the WiFi AP generates the broadcast message, determining the preset type identifier as the value of the type identifier field.

S202, the WiFi AP sends a broadcast message, and the broadcast message is used for indicating the WiFi Station to determine the type of the WiFi hotspot.

And S203, the WiFi Station analyzes the broadcast message to determine the type of the WiFi hotspot.

The WiFi AP periodically broadcasts messages, the WiFi Station analyzes the received broadcast messages, and the type of the WiFi hot spot is determined according to the corresponding type identification field in the broadcast messages.

For example, taking the broadcast message as the Beacon message as an example, after receiving the Beacon message, the WiFi Station parses the Beacon message, identifies the type of the WiFi hotspot according to the AP FIX field therein, determines that the WiFi hotspot is a fixed hotspot if the AP FIX field is 1, and determines that the WiFi hotspot is a mobile hotspot if the AP FIX field is 2.

In the method for identifying the type of the WiFi hotspot provided in this embodiment, the WiFi AP carries the type identifier of the WiFi hotspot in the broadcast message, so that the WiFi Station can determine the type of the WiFi hotspot according to the received broadcast message, thereby ensuring the accuracy of identifying the type of the WiFi hotspot. In addition, because the type identifier of the WiFi hotspot is in the broadcast message of the WiFi AP, the WiFi Station can receive the broadcast message without connecting to the WiFi AP, and analyzes the broadcast message to determine the type of the WiFi hotspot, and does not need to determine after connecting. The WiFi Station may also determine the type of the WiFi hotspot of each WiFi AP according to the received broadcast message of multiple WiFi APs, and correspondingly select an access WiFi hotspot, for example, the WiFi Station may preferentially access a fixed hotspot.

On the basis of the method, the WiFi Station can determine whether to execute preset operation according to the type of the WiFi hotspot. For example, still taking the terminal to execute the positioning function as an example, if the WiFi hotspot is a mobile hotspot, the positioning function is triggered to obtain the current position information; and if the WiFi hotspot is a fixed hotspot, directly using historical positioning information after the WiFi hotspot is connected for the first time without restarting positioning. In an example, in a scene where a user watches or downloads a video by using a terminal, if the terminal judges that a WiFi hotspot is a fixed hotspot, the video is continuously played or downloaded; and if the WiFi hotspot is judged to be a mobile hotspot, pausing playing or downloading the video.

In addition, after the WiFi Station determines the type of the WiFi hotspot, a prompt message can be output on the user interface, and the prompt message is used for prompting the type of the WiFi hotspot of the user. Therefore, the user may manually select the accessed WiFi hotspot according to the type of the WiFi hotspot, or the user may perform corresponding operations according to the type of the accessed WiFi hotspot, for example, the user may download a larger file or application program after accessing the fixed hotspot.

In the above embodiments, it is explained that the WiFi hotspot type identifier of the WiFi AP may be configured by a manufacturer according to the product form when the manufacturer produces a product. However, in some scenarios, a device configured as a fixed hotspot at the factory may also be applied in a mobile scenario, thereby becoming a mobile hotspot in practical applications. For example, WiFi hotspots have been gradually distributed on vehicles such as buses, buses or high-speed rails, and in these usage scenarios, WiFi APs which are all gateway type are generally installed on the vehicles, that is, fixed WiFi hotspots are applied in mobile scenarios, and these WiFi APs provide internet access function through a Subscriber Identity Module (SIM card), as shown in fig. 3. In these scenarios, the type identification fields of the WiFi hotspots of the WiFi APs are initially the factory-set values representing fixed hotspots, but it is obvious that these type identification fields are incorrect in the mobile scenario.

In order to solve the problem, the application also provides a method for the WiFi AP to dynamically modify the type identifier of the WiFi hotspot. When the type identification indicates that the type of the WiFi hotspot is a fixed hotspot, acquiring first cell information registered at the current moment of the WiFi AP and second cell information registered at the historical moment; and if the first cell information is different from the second cell information, modifying the type identifier of the WiFi hotspot, wherein the modified type identifier of the WiFi hotspot indicates that the type of the WiFi hotspot is a mobile hotspot.

For a WiFi AP whose type identifier is a fixed hotspot when leaving a factory, in order to determine whether the WiFi AP is applied to a mobile scene, it is necessary to determine cell information registered in the WiFi AP. If the WiFi AP is moving, its location at different times will change, and the corresponding registered cell will also change. The WiFi AP compares first cell information registered at the current moment with second cell information registered at the historical moment, if the first cell information is different from the second cell information, the fact that the cell information registered by the WiFi AP changes within a period of time is determined, the WiFi AP is represented to be in movement, namely the WiFi AP is used as a mobile hotspot, and therefore the type identification of the WiFi AP needs to be modified, and the type identification is modified to be a value representing the mobile hotspot.

After the WiFi AP modifies the type identifier of the WiFi hotspot, when sending the broadcast message, the type identifier carried in the broadcast message is the modified type identifier, so that the WiFi Station can determine that the type of the WiFi hotspot is a mobile hotspot according to the modified type identifier in the received broadcast message.

For example, a gateway-like WiFi AP is installed on a high-speed rail, and when the WiFi AP is used for the first time, the AP FIX field in the Beacon message broadcasted by the WiFi AP for the beginning period of time is 1, which indicates that the WiFi hotspot is a fixed hotspot. After the high-speed rail walks for a period of time, due to the fact that the cells registered by the WiFi AP are correspondingly changed after passing through different places, the WiFi AP automatically modifies the AP FIX field in the broadcast Beacon message into 2 according to the change of the cell information, and the fact that the WiFi hotspot is a mobile hotspot is indicated.

According to the method provided by the embodiment, the WiFi AP can dynamically modify the type identifier of the WiFi hotspot to adapt to different application scenes, so that the condition that the initial configuration is inconsistent with the actual use scene is avoided, and the type identification correctness of the WiFi hotspot is further ensured.
