It will be apparent that the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without the need for inventive faculty, are within the scope of the present disclosure, based on the described embodiments of the present disclosure.
In the present application, each term has its meaning commonly understood in the art, unless specifically indicated otherwise or understood by context. The terms commonly used in the present application are terminals, such as registration terminal, login terminal, first terminal, second terminal, online terminal, terminal of interest, etc., which terms are expressed in the context of the specific claims and the technical solutions as terminal devices. However, in describing some subjective actions or behaviors occurring in connection with the terminal behind the technical solution of the present application, reference to the terminal or the terminal user refers to the user of the terminal, or in a specific context, the terminal will also be understood as the terminal user, or it will be understood by those skilled in the art that "terminal" and "terminal user" may be used interchangeably in a specific case, but in describing specific claims and technical solution, the terminal refers only to the terminal device. The application has no special limitation on the operating system operated by the terminal, and the terminal can operate an Android operating system or an iOS operating system and the like.
In the present application, the term "terminal logged in to a server" includes terminals logged in to a server by various means, including terminals registered in a server, terminals logged in by means of third party authentication, and the like. The term "remote positioning device" in the present application refers to a device capable of acquiring the position of a terminal in a large range (such as in a range of several kilometers, several tens of kilometers, or even more than several hundred kilometers), and generally includes a GPS positioning device and a Beidou positioning device. The term "short-range positioning device" in the present application refers to a device having a positioning function within a short distance, wherein the positioning function generally refers to wireless positioning, such as bluetooth positioning means, infrared positioning means, wifi positioning means, RFID positioning means, which are characterized by a short positioning distance, typically within 20 meters, and positioning between them is different from GPS positioning means or Beidou positioning means using satellites. In practice, a frequently used positioning method also includes positioning a base station, and a mobile phone base station positioning service is called mobile location service (LBS-Location Based Service), which is a value added service for providing corresponding services for users under the support of an electronic map platform, such as a dynamic location query service provided by the current china mobile dynamic zone, etc., by acquiring the location information (latitude and longitude coordinates) of a mobile terminal user through a network (such as a GSM network) of a telecom mobile operator. The term "WLAN hotspot device" in the present application is a device providing wireless access services, such as a router. WLAN is all called: wireless Local Area Networks, chinese is interpreted as: the wireless local area network is a system for data transmission by utilizing the radio frequency (Radio Frequency RF) technology, and the technology is used for replacing the wired local area network in no way, but is used for making up the defects of the wired local area network so as to achieve the purpose of network extension, so that the wireless local area network can utilize a simple access architecture to enable a user to pass through the wireless local area network, and realize a clear network without network wires and distance limitation. WIFI (wireless fidelity) technology is a brand of wireless network communication technology based on IEEE 802.11 series standards, and aims to improve interoperability between wireless network products based on IEEE 802.11 standards, which is held by Wi-Fi alliance (Wi-FI ALLIANCE), simply referred to as WIFI is a technology of wireless networking. WIFI is a standard of WLAN in terms of inclusion, and WIFI is included in WLAN, which belongs to a new technology in WLAN protocol. The term "WLAN connection device" in the present application refers to a device provided on a terminal that can be used to wirelessly connect the terminal with a WLAN hotspot device. When the WLAN connection device on the terminal scans for a WLAN hotspot device available for connection, the information that can be obtained from the WLAN hotspot device even if the password of the WLAN hotspot device is not known includes: signal strength, WLAN hotspot name, corresponding MAC address, etc. The network signal strength of a WLAN is in dBm (milliwatt decibel), typically expressed as a negative number, and normal signal variation ranges from-110 dBm (difference) to-50 dBm (good), typically-70 dBm to-50 dBm being a better signal strength, in which case the terminal is typically within 20 meters, even within 10 meters, of the WLAN hotspot device. WLAN hotspot names and corresponding MAC addresses are two important distinguishing factors for WLAN hotspot devices, which are typically not frequently modified by merchants and companies in a mall or office building. The location of the WLAN hot spot device, once selected, is not changed frequently for a typical user. These features of WLAN hotspot devices have led to the possibility to use the information of the WLAN hotspot device for positioning. Thus, if the information of each WLAN hotspot device and the accurate address are recorded on the server, the server can help the terminal to perform accurate indoor positioning according to the information. The WLAN hotspot device may typically be a router.
As shown in fig. 1, according to a first aspect of the present application, there is provided a method for performing terminal positioning, including the steps of:
S101, a server stores a hot spot information record table containing at least one hot spot information record, wherein each hot spot information record comprises at least one of the following information: "WLAN hotspot name, corresponding mac address, geographical location information of WLAN hotspot", wherein each hotspot information record optionally comprises a record name (merchant name).
S102, the first terminal logged in to the server opens terminal WLAN connection equipment (i.e. wifi connection) to become an online terminal.
S103, the server sends the hot spot information record list to the first terminal, and the first terminal receives the hot spot information record list from the server.
S104, the first terminal acquires current information, wherein the current information comprises at least one of the following information:
Geographical location information of a first terminal, and
At least one of the following information for WLAN hotspot devices in the vicinity of the first terminal with a signal strength above a threshold (greater than-50 dbm, greater than-65 dbm, or greater than-70 dbm): "WLAN hotspot name, corresponding mac address".
S105, the first terminal judges whether WLAN hotspot equipment near the first terminal with the signal intensity higher than a threshold accords with one hotspot information record in the hotspot information record table, wherein the ' accords with one hotspot information record in the hotspot information record table ' refers to the ' WLAN hotspot name ', corresponding mac address ' and at least one of the geographic position information of the first terminal of the WLAN hotspot equipment near the first terminal contained in the current information are the same as the corresponding ' WLAN hotspot name, corresponding mac address and geographic position information of the WLAN hotspot ' in the hotspot information record.
S106, for the nearby WLAN hotspot equipment conforming to one hotspot information record in the hotspot information record table, the first terminal sends prompt information located nearby the hotspot to a server, wherein the prompt information located nearby the hotspot comprises at least one part of current information and/or at least one part of the hotspot information record, the server receives the prompt information located nearby the hotspot sent by the first terminal and sends information of a second terminal to the first terminal, and the second terminal is at least one of other online terminals conforming to the hotspot information record.
And S107, the first terminal receives the information of the second terminal from the server.
It should be noted that, in the present application, unless there is a logical relationship, the order of the steps is not necessarily required, and thus the relationship between the steps should not be considered as being limited in the claims and the specification.
The method of the present application may include one or more of steps S101 to S107, for example, steps S101 to S105 may implement that the first terminal determines whether itself is near a WLAN hot spot, so as to implement positioning.
In step S101, the server stores a hotspot information record table containing at least one hotspot information record, wherein each hotspot information record includes at least one of the following information: "WLAN hotspot name, corresponding mac address, geographical location information of WLAN hotspot", wherein each hotspot information record optionally comprises a record name (merchant name). In order to locate by using WLAN hotspot devices, information of each WLAN hotspot device needs to be stored on a server. In general, one or more of the WLAN hotspot name, the corresponding mac address, and the geographic location information of the WLAN hotspot may be saved in a hotspot information record. In general, WLAN hotspot names may be renamed, but the corresponding mac address is often unique, and the geographic location information of the WLAN hotspot is also often unique. A WLAN hot spot can be more precisely determined by means of a combination of two of these three information, any combination of which is within the intended scope of the application. It is of course also possible to use three kinds of information for the determination at the same time. The specific form of the hot spot information record and the hot spot information record table is not limited as long as it reflects specific substantial contents. In addition, other information, such as a record name, may be optionally included in the hotspot information record, where the record name may be the name information of a merchant, and when the terminal obtains its location and also can be accurate to the name of the merchant, the accurate sharing of the indoor location is more beneficial, because the name information of the merchant often also includes information such as floors. The server assumes the responsibility of updating the hotspot information record in addition to storing the hotspot information record table. And the server newly adds or updates the hot spot information record table according to the modes of reporting by the user and the like.
In step S102, the first terminal logged into the server opens the terminal WLAN connection device (i.e., wifi connection) to become an online terminal. The first terminal is one of the online terminals, which can log in to the server in any way. The WLAN connection device is a functional unit on the first terminal for connecting to the WLAN hotspot device, and the first terminal obtains relevant information of the WLAN hotspot device, such as signal strength, WLAN hotspot name, corresponding MAC address, and the like, through the WLAN connection device.
In step S103, the server sends the hotspot information record table to the first terminal, and the first terminal receives the hotspot information record table from the server. After the first terminal downloads the hotspot information record table from the server, the first terminal can automatically compare according to the scanned information.
In step S104, the first terminal acquires current information including at least one of the following information:
Geographical location information of a first terminal, and
At least one of the following information for a WLAN hotspot device in the vicinity of which the signal strength is above a threshold: "WLAN hotspot name, corresponding mac address". The first terminal acquires current information, and then the current information is used for comparing with information in the hot spot information record table. It should be noted that the WLAN hotspot information that can act on the positioning is only a WLAN hotspot with a higher signal strength, and the lower signal strength means a longer distance, and thus has no meaning for positioning. In general, a signal strength of a WLAN hotspot greater than-70 dbm indicates a stronger signal, e.g., greater than-68 dbm, greater than-65 dbm, or greater than-50 dbm. Thus, in the present application, the threshold may be a number from-70 dbm to-50 dbm, such as-70 dbm or-65 dbm. In the present application, the manner of acquiring the position information of the first terminal is not limited, and may be by GPS positioning, wifi positioning, base station positioning, or a combination of multiple manners.
In step S105, the first terminal determines whether the WLAN hotspot device near the first terminal with the signal strength higher than the threshold accords with one hotspot information record in the hotspot information record table, where the "accords with one hotspot information record in the hotspot information record table" refers to that at least one of the "WLAN hotspot name, the corresponding mac address" and the geographic location information of the first terminal of the nearby WLAN hotspot device included in the current information is the same as the corresponding "WLAN hotspot name, the corresponding mac address and the geographic location information of the WLAN hotspot" in the hotspot information record. It should be noted that, although at least one piece of information is identical, that is, it is considered to be coincident, in the case where two pieces of information are used for the combination comparison, it should be considered that "coincident with one piece of hotspot information record in the hotspot information record table" means that the two pieces of information are identical accordingly. In the case of using three kinds of information for the combination comparison, it should be considered that "conforming to one piece of the hotspot information record in the hotspot information record table" means that the three kinds of information are identical accordingly. It should be noted that the fact that the geographical location information of the first terminal included in the current information is identical to the geographical location information of the corresponding "WLAN hotspot" in the hotspot information record means that the difference in location between the two geographical location information is less than 500 meters, such as less than 300 meters, such as less than 200 meters, such as less than 150 meters, such as less than 100 meters, such as less than 80 meters, such as less than 50 meters, such as less than 20 meters. In this case, the current location of the first terminal may be modified to the location in the hotspot information record in order to directly follow the location of the first terminal to the location of the stronger-signaling WLAN hotspot device. Such positioning accuracy is sufficient in daily life.
The method of the first aspect of the present invention may be implemented in a client side and a server side, respectively, and therefore the first aspect of the present invention also includes a client side method and a server side method for implementing the method, respectively.

The first terminal judges whether the WLAN hotspot equipment near the first terminal with the signal intensity higher than the threshold accords with one hotspot information record in the hotspot information record table, wherein the 'accords with one hotspot information record in the hotspot information record table' refers to that the current information contains 'WLAN hotspot names, corresponding mac addresses' of the WLAN hotspot equipment near the first terminal and at least one of geographic position information of the first terminal is the same as the corresponding 'WLAN hotspot names, corresponding mac addresses and geographic position information of the WLAN hotspots' in the hotspot information record.
In some embodiments, the client method further includes, for a WLAN hotspot device near a first terminal that conforms to one hotspot information record in the hotspot information record table, the first terminal sending a hint information near the hotspot to a server, where the hint information near the hotspot includes "at least a portion of current information" and/or "at least a portion of the one hotspot information record".
In some embodiments, the client method further comprises at least one of the following steps:
For WLAN hotspot equipment near a first terminal which accords with one hotspot information record in the hotspot information record table, the first terminal modifies the current position of the first terminal into the position of 'geographic position information of WLAN hotspot' in the hotspot information record; and
The first terminal enters a map interface, and obtains the distribution condition of the online terminals with the positions in the range shown by the map on the map from a server.
In some embodiments, the client method further comprises the first terminal receiving information of at least one second terminal from the server, the second terminal being another online terminal that also conforms to the piece of hotspot information record.
In some embodiments of the client method, the WLAN hotspot refers to a "wifi hotspot", and the WLAN connection device refers to a wifi connection device provided on the terminal.
In some embodiments of the client method, the current information includes the same geographic location information of the first terminal as the corresponding "geographic location information of the WLAN hotspot" in the hotspot information record, which means that the difference in location between the two geographic location information is less than 500 meters, such as less than 300 meters, such as less than 200 meters, such as less than 100 meters, such as less than 80 meters, such as less than 50 meters, such as less than 20 meters.
In some embodiments of the client method, the WLAN hotspot device near the first terminal with the signal strength higher than the threshold value refers to a WLAN hotspot device near the first terminal, which is scanned by the first terminal through the terminal WLAN connection device, and has a signal strength greater than-50 dbm, such as greater than-65 dbm, or such as greater than-70 dbm.
In some embodiments of the client method, the first terminal sends an instruction to the server that it wants to establish contact with at least one second terminal, the at least one second terminal receives a reminder sent by the server whether to agree to establish contact with the first terminal, and sends a message of agreement or disagreement to the server.
In some embodiments of the client method, when the first terminal closes the WLAN connection device, the first terminal sends a message of "closing the WLAN connection device" to the server.
In some embodiments of the client method, the first terminal sends an instruction to the server to obtain at least one of the invited feature information and at least a portion of the registration information for the at least one second terminal, and obtains at least one of the invited feature information and at least a portion of the registration information for the second terminal from the server.
In some embodiments of the client method, when the first terminal sends an instruction to the server that the first terminal wants to establish contact with the second terminal, the first terminal points horizontally to the second terminal to form a direction vector, the direction vector formed by the first terminal is obtained, that is, the direction vector pointing from the first terminal to the second terminal, the data related to the direction vector is sent to the server,
The second terminal receives the data related to the direction vector from the server and obtains the opposite direction vector, i.e. the direction of the first terminal relative to the second terminal.
The application is not limited to the specific contact mode of the first terminal and the second terminal. In some cases, it is possible that the user of the first terminal has found the user of the second terminal, but the user of the second terminal is not aware. At this time, the method of the present application further provides a manner in which the first terminal contacts the second terminal as follows: after the first terminal is horizontally and positively pointed at the second terminal, a direction vector is formed, i.e. the direction of the second terminal relative to the first terminal (i.e. the direction from the first terminal to the second terminal is obtained by calling the compass tool of the terminal), the data related to the direction vector is sent to the server, the server sends the data related to the direction vector to the second terminal, the second terminal receives the data related to the direction vector, and an opposite direction vector is obtained, i.e. the direction of the first terminal relative to the second terminal (when the second terminal is horizontally and positively pointed at the first terminal along the opposite direction vector, the second terminal is pointed at the first terminal). In this way, the direction vector is added to the invitation of the first terminal, and the second terminal can conveniently and accurately find the first terminal by using the vector information. The compass tool in the application refers to a tool which is carried in terminal equipment and can distinguish the forward direction of the terminal, and comprises hardware equipment and a software interface, wherein the hardware equipment and the software interface are realized by using the principle of geomagnetic field, and the compass tool is also called compass in certain occasions. The application refers to a direction vector, which refers to a direction that one terminal points to another terminal, when the terminal acquires data related to the direction vector, the direction vector is considered to be acquired, and when the terminal transmits the data related to the direction vector, the direction vector is considered to be transmitted. The specific form of the direction vector and the specific form of the transmission direction vector are not limited, and any manner is within the intended scope of the present application as long as the information can be transferred. For example, the terminal acquires various coordinate values, such as the coordinate values r and θ in polar coordinates, or the coordinate values x and y in cartesian coordinates, and can be considered to acquire the direction vector as long as it can reflect the direction vector, and the data transmitted by the terminal can be considered to be data related to the direction vector as long as the data includes data capable of resolving the direction vector (for example, the coordinate value, or a certain transformation of the coordinate value such as the negative number of the coordinate value).
