Description

Targeting methods and platforms

technical field

The invention belongs to the technical field of wireless communication, and in particular relates to a positioning method and a platform.

Background technique

With the rapid development of mobile Internet and smart terminals, the application range of positioning services has become more and more extensive. From the perspective of technical principles, current positioning technologies can be divided into two types: active positioning and passive positioning.

Active positioning, in simple terms, is a user's initiative to initiate a positioning request for the terminal device held by the user to obtain the current location information of the user. Active positioning is currently mainly based on the mature Global Positioning System (Global Positioning System, hereinafter referred to as GPS) positioning technology. The GPS positioning technology has the advantage of high positioning accuracy, so the GPS-based positioning technology is referred to as the precise positioning method for short. However, limited by the coverage of GPS signals, GPS signals cannot be found in signal blind areas or indoors, so GPS-based positioning cannot be realized.

Passive positioning is simply a positioning request initiated by others to the terminal device held by the user. At present, it is mainly based on the wireless positioning technology of the mobile network. The basic principle of this technology is that the positioning platform on the operator's side initiates signaling interaction with the signaling gateway on the operator's network side to obtain the ID of the cell that provides services for the target mobile terminal, and maps the cell ID information into longitude and latitude information. The location of the target mobile terminal is determined. Although passive positioning can avoid the coverage problem of wireless network signals through mobile network wireless positioning technology, the positioning accuracy is very low. Therefore, the passive positioning method based on mobile network wireless positioning technology is referred to as the coarse positioning method.

With the continuous development of application services such as location-based services, applications such as monitoring and dispatching of vehicles such as taxis, buses, long-distance vehicles, and special vehicles are not uncommon. These applications are all based on passive positioning, that is, rough positioning. However, although simple coarse positioning can achieve better coverage of wireless signals, the positioning accuracy is low, and the signaling interaction between the positioning platform and the operator's network-side equipment during the positioning process will cause an excessive load on the operator's signaling network pressure.

Contents of the invention

In view of the above existing problems, the present invention provides a positioning method and platform to overcome the defects of low positioning accuracy and large signaling overhead in the existing coarse positioning technology.

The invention provides a positioning method, including:

receiving a location query request sent by the inquirer, the location query request including the identification information of the queried person, and the location query request is used to query the current location information of the queried person;

determining user terminal state information corresponding to the identification information from a local user terminal state database, the user terminal being a terminal corresponding to the queried person;

determining a positioning mode corresponding to the state information of the user terminal, where the positioning mode includes a precise positioning mode and a coarse positioning mode;

Obtain the location information of the user terminal according to the determined positioning method.

The invention provides a positioning platform, comprising:

A receiving module, configured to receive a location query request sent by an inquirer, the location query request includes identification information of the queried person, and the location query request is used to query the current location information of the queried person;

In the passive positioning scenario, based on the status information of the user terminal of the queried user, when the status information of the user terminal meets certain conditions, the location information can be obtained by means of precise positioning, instead of relying entirely on the coarse positioning method. Therefore, the positioning accuracy is improved to a certain extent, and the signaling overhead for signaling interaction between the positioning platform and the wireless network side device is also greatly reduced.

Detailed ways

FIG. 1 is a flow chart of Embodiment 1 of the positioning method of the present invention. The method provided in this embodiment can be executed by a positioning platform on the operator side. This embodiment is mainly applicable to passive positioning scenarios, that is, the queryer queries the location information of the queried person through the positioning platform. As shown in Figure 1, the method includes:

Step 101. Receive a location query request sent by the inquirer, the location query request includes identification information of the queried person, and the location query request is used to query the current location information of the queried person;

Step 102. Determine user terminal state information corresponding to the identification information from a local user terminal state database, where the user terminal is a terminal corresponding to the queried person;

Step 103: Determine a positioning method corresponding to the user terminal state information, the positioning method includes a precise positioning method and a coarse positioning method;

Step 104. Obtain the location information of the user terminal according to the determined positioning method.

In the existing passive positioning method, after receiving the location query request from the inquirer, the positioning platform determines the network-side device corresponding to the queried person, interacts with the network-side device, and passes the existing coarse positioning based on mobile wireless network positioning. The location of the user terminal of the queried user is not only low in location accuracy, but also often leads to heavy signaling overhead in the mobile wireless network.

For this reason, in this embodiment, when the positioning platform receives the location query request from the queryer for querying the location information of the queried person, first, according to the identification information of the queried person contained in the location query request, the user terminal stored locally The user terminal state information corresponding to the identification information is determined in the state database, that is, the state information of the user terminal of the inquired person. Wherein, the identification information of the queried person may be, for example, a name identification of the queried person, a terminal identification such as a telephone number, and other identification information.

In the positioning platform, a user terminal state database is pre-established and maintained, in which the correspondence between the identification information of the owner of each user terminal and its state information is stored. Wherein, the state information of the user terminal includes whether the positioning client is installed in the user terminal and whether the client is online. Wherein, the positioning client is a client for obtaining the location information of the user terminal in a precise positioning manner. With the popularization of smart terminals, most of the current smart terminals can support the installation of the positioning client. For example, the positioning client can have location information for locating the user terminal through the GPS positioning technology. The positioning platform can obtain the information of whether the user terminal is installed with the positioning client in the form of registering with the positioning platform when the user terminal installs the positioning client. Whether the positioning client is online or not describes the network connection between the user terminal where the client is located and the positioning platform. Simply put, if the positioning client is online on the corresponding user terminal, it means that the user terminal is connected to the positioning platform The network connection between platforms is in good condition, and the user terminal is in an area that can be covered by GPS signals. Whether the positioning client is online can be determined by the positioning platform, for example, when it receives a query positioning request or periodically sends a detection message to the user terminal. If the client feeds back a confirmation response message, it means that it is online.

Therefore, after the positioning platform obtains the status information of the user terminal of the queryee according to the identification information of the queryee included in the positioning query request, it determines which positioning method to use to obtain the location information of the queryee according to the obtained user terminal status information .

Specifically, FIG. 2 is a flow chart of Embodiment 2 of the positioning method of the present invention. As shown in FIG. 2, on the basis of the embodiment shown in FIG. , the positioning method includes a precise positioning method and a coarse positioning method, which can be specifically implemented in the following ways:

Step 201, if the user terminal state information indicates that the user terminal has not installed the positioning client, or the user terminal state information indicates that the user terminal has the positioning client installed, but the positioning client is not installed online, determining that the positioning mode corresponding to the user terminal status information is the coarse positioning mode;

Step 202. Obtain the location information of the user terminal according to the coarse positioning method.

Specifically, if the positioning platform determines that the user terminal of the queried does not have a positioning client installed according to the status information of the user terminal of the queried, or the positioning client is not online although the positioning client is installed, it means that the user of the queried The terminal either does not support precise positioning, or the current network status is not good, and the location information of the queried party cannot be obtained through precise positioning. At this time, the positioning platform determines to obtain the location information of the queried person in a coarse positioning manner, that is, obtains the location information of the user terminal of the queried person. Specifically, the process of obtaining the location information of the user terminal of the inquirer in the coarse positioning method is similar to the coarse positioning method in the prior art, and will not be repeated here.

Step 203: If the user terminal state information indicates that the user terminal is installed with the positioning client and the positioning client is online, then determine that the positioning method corresponding to the user terminal state information is the precise positioning method ;

Step 204. Obtain the location information of the user terminal according to the precise positioning method.

On the contrary, if the positioning platform determines that the user terminal of the queried user has installed the positioning client according to the status information of the user terminal of the queried person, and the positioning client is online, it means that the user terminal of the queried person does not support precise positioning methods, and the current The network status of is good. At this time, the positioning platform determines to obtain the location information of the queried person in a precise positioning manner, that is, obtains the location information of the user terminal of the queried person.

Specifically, obtaining the location information of the queried user terminal in a precise positioning manner can be achieved in the following manner:

The positioning platform sends a query command to the positioning client of the queried user terminal to query the current location information of the user terminal. After receiving the query command, the positioning client immediately starts the precise positioning function, that is, the GPS positioning function, The location information of the GPS positioning is obtained, and the location information is fed back to the positioning platform.

In addition, it is worth noting that there is another special case, that is, although the positioning platform determines to obtain the position information of the queried person by means of precise positioning according to the state information of the user terminal of the queried person. However, in practical applications, it is possible that the user temporarily turns off the GPS device or prohibits the positioning client from obtaining the location information through security software, so that the positioning client cannot obtain the location information through the GPS. At this time, the positioning platform cannot obtain the location information fed back by the positioning client, and will soon receive a positioning failure response from the positioning client. At this time, the positioning platform will further determine to use a coarse positioning method to obtain the location information of the queried person.

In another optional embodiment, the location inquiry request sent by the inquirer can also be used to inquire about the movement trajectory of the inquired person, that is, to inquire about the movement trajectory of the inquired person within a certain time period. At this time, it is only an example to obtain different location information of the queried person in the way of precise positioning:

After the positioning platform determines to adopt the precise positioning method according to the status information of the user terminal of the queried person, it periodically obtains various location information of the user terminal of the queried person according to the precise positioning method, and determines its trajectory according to the various location information. That is, the positioning platform periodically sends query commands to the positioning client at preset time intervals, so that the positioning client periodically obtains its own location information and feeds it back to the positioning platform. The positioning platform records the location information in chronological order, Thus depicting the trajectory of the person being queried. Therefore, the accurate tracking of the movement track of the inquired person can be realized through the periodic precise positioning method.

In this embodiment, when the positioning platform receives the location query request sent by the queryer for querying the location information of the queried person, it first searches the locally stored user terminal status database according to the identification information of the queried person included in the location query request. Determine the state information of the user terminal corresponding to the queried person, and then select and determine the corresponding positioning method according to the determined user terminal state information, and obtain the position of the queried user terminal in the determined positioning method, that is, the precise positioning method or the coarse positioning method information to obtain the location information of the person being queried. In the scenario of passive positioning, based on the state information of the user terminal of the queried user, when the state information of the user terminal meets certain conditions, the location information can be obtained by means of precise positioning, instead of relying entirely on the rough positioning method. Therefore, the positioning accuracy is improved to a certain extent, and the signaling overhead for signaling interaction between the positioning platform and the wireless network side device is also greatly reduced.
