Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

Embodiment one

Figure 1 is a flow chart of a method for connecting to a WiFi hotspot provided by Embodiment 1 of the present invention. This embodiment is applicable to the case where a mobile terminal reconnects to a WiFi hotspot that has been successfully connected. The device can be implemented by software and/or hardware, and generally can be integrated into a mobile terminal such as a mobile phone or a tablet computer. The method specifically includes the following steps:

Step 110, obtaining the name and password of the WiFi hotspot, and obtaining the corresponding current geographic location.

When detecting that the user turns on the WLAN (Wireless Local Area Networks, wireless local area network) switch or detecting that the searched WiFi hotspot changes, obtain the name of the WiFi hotspot that can be searched, and obtain and save based on the name of the searched WiFi hotspot corresponding password. And obtain the current geographic location based on the positioning technology. Wherein, the WiFi hotspot may not have a password when it belongs to a public WiFi hotspot, and the obtained password at this time is empty. The current geographic location may be expressed in latitude and longitude coordinates.

Among them, WLAN is a system that uses radio frequency technology for data transmission. The emergence of this technology makes up for the shortcomings of wired local area networks and achieves the purpose of network extension. Realize a smooth network without network cables and without distance restrictions. WiFi technology is a brand of wireless network communication technology based on IEEE 802.11 series standards, the purpose is to improve the interoperability between wireless network products based on IEEE 802.11 standards, held by Wi-Fi Alliance (Wi-FiAlliance), Simply put, WiFi is a wireless networking technology. WiFi is a trademark of WLANA (Wireless Local Area Networks, Wireless Local Area Network Alliance). This trademark only guarantees that products using this trademark can cooperate with each other, and has nothing to do with the standard itself. It is customary to use WiFi to call the 802.11b protocol. In terms of inclusion, WiFi is a standard of WLAN, and WiFi is included in WLAN, which is a new technology using WLAN protocol.

Among them, to obtain the corresponding current geographic location, options include:

The current geographic location of the WiFi hotspot is determined by GPS (Global Positioning System, Global Positioning System) positioning or base station positioning.

Wherein, the current geographic location of the WiFi hotspot is the current geographic location of the mobile terminal when the WiFi hotspot is obtained.

GPS is a satellite navigation and positioning system established by the United States. With this system, users can realize all-weather, continuous, real-time three-dimensional navigation, positioning and speed measurement around the world; precision positioning. The whole system of GPS is composed of space part, ground control part and user part. The space part of GPS is composed of 24 GPS working satellites. These GPS working satellites together form a GPS satellite constellation, of which 21 are satellites that can be used for navigation, and 3 are active backup satellites. These 24 satellites are distributed in 6 Each GPS working satellite sends out signals for navigation and positioning. The control part of GPS is composed of a monitoring system composed of several tracking stations distributed all over the world. According to their different functions, these tracking stations are divided into master control station, monitoring station and injection station. There is one master control station, which is located at the Falcon Air Force Base in Colorado, USA. Its function is to calculate the satellite ephemeris and satellite clock correction parameters based on the observation data of GPS from each monitoring station. etc., and inject these data into the satellite through the injection station; at the same time, it also controls the satellite, issues instructions to the satellite, and dispatches a backup satellite to replace the failed working satellite when the working satellite fails; in addition, the main The control station also has the function of a monitoring station. There are five monitoring stations. Except for the main control station, the other four are located in Hawaii, Ascension, Diego Garcia, and Kwajalein. The function is to receive satellite signals and monitor the working status of the satellite; there are three injection stations, which are located in Ascension, Diego Garcia, and Kwajalein. The satellite ephemeris and satellite clock corrections calculated by the master control station are injected into the satellite. The user part of GPS is composed of GPS receiver, data processing software and corresponding user equipment such as computer meteorological instruments, etc. Its function is to receive the signals sent by GPS satellites and use these signals for navigation and positioning.

Base station positioning is generally applied to mobile phone users. The mobile phone base station positioning service is also called location based service (Location Based Service, LBS). , a value-added service that provides users with corresponding services with the support of the electronic map platform. The general principle of base station positioning is: the mobile phone measures the downlink pilot signals of different base stations, and obtains the TOA (Time of Arrival, time of arrival) or TDOA (Time Difference of Arrival, time difference of arrival) of the downlink pilot signals of different base stations. Combined with the coordinates of the base station, the location of the mobile phone can be calculated by generally using the triangular formula estimation algorithm. The actual location estimation algorithm needs to consider the positioning of multiple base stations (3 or more), so the algorithm is much more complicated. Generally speaking, the more the number of base stations measured by the mobile station, the higher the measurement accuracy and the more obvious the improvement of positioning performance.

Step 120, according to the name of the WiFi hotspot, obtain the historical geographic location of the WiFi hotspot.

Wherein, after each successful connection to the WiFi hotspot, the mobile terminal also saves the current geographic location correspondingly when saving the name and password of the WiFi hotspot, and this geographic location becomes the historical geographic location when subsequently connecting to the WiFi hotspot. A WiFi hotspot may correspond to multiple historical geographic locations, that is, when WiFi hotspots located in different places have the same name, the WiFi hotspot will correspond to multiple historical geographic locations, and the distance between these multiple historical geographic locations is greater than the preset distance. Set the distance threshold.

In the saved correspondence between the WiFi hotspot and the historical geographic location, query the name of the WiFi hotspot, and obtain the historical geographic location corresponding to the queried name of the WiFi hotspot. Wherein, the historical geographic location is the geographic location where the WiFi hotspot was connected before, and the representation form of the historical geographic location is the same as that of the current geographic location, that is, it can also be represented by latitude and longitude coordinates.

Step 130, determining the distance between the current geographic location and the historical geographic location.

Calculate the distance between the current geographic location and the historical geographic location. When the current WiFi hotspot corresponds to multiple historical geographic locations, the distances between the current geographic location and each historical geographic location are calculated respectively.

Step 140, when the distance is less than or equal to a preset distance threshold, connect to the WiFi hotspot according to the password.

When the distance between the current geographic location and the historical geographic location is less than or equal to the preset distance threshold, it means that the current geographic location and the historical geographic location are in the same place, and the WiFi hotspot is connected according to the corresponding password. When the current WiFi hotspot corresponds to multiple historical geographic locations, as long as the distance between the current geographic location and one of the multiple historical geographic locations is less than or equal to a preset distance threshold, the WiFi hotspot is connected.

In the technical solution of this embodiment, when obtaining the name and password of the WiFi hotspot, the corresponding current geographic location is also obtained, and the distance between the current geographic location and the historical geographic location of the WiFi hotspot is determined. When the distance threshold is set, the WiFi hotspot is connected according to the corresponding password, and the distance between the current geographic location and the historical geographic location is less than or equal to the preset distance threshold, indicating that the current location and history of the mobile terminal are successfully connected to the WiFi hotspot The location is the same, thereby avoiding the leakage of user information caused by the direct connection of the mobile terminal searching for a WiFi hotspot with the same name and password when it is in a different geographical location, and improving the security of user information.

On the basis of the above technical solution, obtain the name and password of the WiFi hotspot, including:

When searching for a WiFi hotspot, match the name of the searched WiFi hotspot with the name of the saved WiFi hotspot;

If the name of the searched WiFi hotspot is the same as the name of the saved WiFi hotspot, the corresponding password is obtained according to the saved name of the WiFi hotspot.

Wherein, each time the mobile terminal successfully connects to a WiFi hotspot, it will save the name of the WiFi hotspot and the corresponding password.

When a WiFi hotspot is found, the name of the WiFi hotspot will be obtained directly, and the name of the WiFi hotspot will be matched with the name of the saved WiFi hotspot. If they are the same, the password corresponding to the name of the saved WiFi hotspot will be obtained. The password for the WiFi hotspot.

Step 210, obtaining the name and password of the WiFi hotspot, and obtaining the corresponding current geographic location.

Step 220, according to the name of the WiFi hotspot, obtain the historical geographic location of the WiFi hotspot.

Step 230, determining the distance between the current geographic location and the historical geographic location.

Step 240, when the distance is less than or equal to a preset distance threshold, connect to the WiFi hotspot according to the password.

Step 250, prompting the user when the distance is greater than the preset distance threshold.

When the current WiFi hotspot corresponds to a historical geographic location, if the distance between the current geographic location and the historical geographic location is greater than the preset distance threshold, it is determined that the current geographic location and the historical geographic location are in different places, that is, WiFi with the same name and the same password The hotspots are in different locations, and at this time, the user is prompted, and the user determines the security of the current WiFi hotspot. When the current WiFi hotspot corresponds to multiple historical geographic locations, and the distance between the current geographic location and all historical geographic locations among the multiple historical geographic locations is greater than the preset distance threshold, a prompt is given to the user, and the user determines the current WiFi hotspot security. Exemplarily, the content of the specific prompt may be: the current geographic location of the current WiFi hotspot does not match the historical geographic location, please confirm whether to connect. Of course, this is only an example, and the content of the prompt may also be other content.

Step 260, if an instruction from the user to confirm the connection is received, connect to the WiFi hotspot according to the password.

When the user confirms that the WiFi hotspot can be connected, he can click Confirm. If an instruction from the user to confirm the connection is received, the WiFi hotspot is connected according to the password of the WiFi hotspot.

Among them, after prompting the user, you can also optionally include:

If an instruction to cancel the connection from the user is received, the connection to the WiFi hotspot is canceled, and the current geographic location corresponding to the name of the WiFi hotspot is added to the blacklist.

If an instruction to cancel the connection from the user is received, it indicates that the user thinks that the WiFi hotspot is not safe in the current geographic location, and the current geographic location corresponding to the name of the WiFi hotspot can be added to the blacklist, and subsequently the WiFi hotspot is in the current geographic location. When the WiFi hotspot with the name of the WiFi hotspot is found again, the WiFi hotspot is no longer connected to avoid leakage of user information.

In the technical solution of this embodiment, when the distance between the current geographic location of the WiFi hotspot and the historical geographic location of the WiFi hotspot is greater than the preset distance threshold, the user is prompted, and if an instruction from the user to confirm the connection is received, the The password is connected to the WiFi hotspot, which realizes prompting the user to the WiFi hotspot with the same name and password in different geographical locations, and improves the security of user information.

On the basis of the above technical solution, after receiving an instruction from the user to confirm the connection, after connecting to the WiFi hotspot according to the password, it may also optionally include:

Adding the corresponding relationship between the name of the WiFi hotspot and the current geographic location, and saving the corresponding relationship.

If the instruction of the user confirming the connection is received, it is determined that the WiFi hotspot is safe at the current geographic location, and the current geographic location is correspondingly added to the name of the WiFi hotspot, and saved, so that the searched location can be found later. When describing the name of the WiFi hotspot, it is used as the historical geographic location and as a reference for subsequent connections.
