Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1A is a diagram illustrating an example of a scenario in which the location determining method of the present disclosure is applied, which includes: a first terminal 110 and a second terminal 120; the first terminal 110 and the second terminal 120 are connected to communicate the relevant information in the location determination method of the present disclosure. The communication method between the first terminal 110 and the second terminal 120 is not limited, and may be, for example, communication via the internet, a local area network, or the like.

In a possible implementation manner, the disclosed location determining method may be more specifically applied to instant messaging tools of the first terminal 110 and the second terminal 120, such as chat, wechat, and the like, and at this time, the first terminal 110 and the second terminal 120 may communicate the relevant information in the disclosed location determining method through the instant messaging tools in the terminals. At this time, referring to fig. 1B, the first terminal 110 and the second terminal 120 may be connected to the server 130 of the instant messenger through the internet, and the information to be transmitted between the two terminals may be forwarded through the server 130 of the instant messenger.

In the present disclosure, a user using a first terminal is referred to as a first user, and a user using a second terminal is referred to as a second user, that is, the first user is a user to which the first terminal belongs, and the second user is a user to which the second terminal belongs. The first user and the second user in the present disclosure may be represented by a user identification. When the embodiment is applied to an instant messaging tool of a terminal, the user identifier may be implemented by a user name of a user in the instant messaging tool, for example, a user name of a first user in a chat of the instant messaging tool is: juli1, the first user identification may be: juli 1; the user name of the second user in the instant messaging tool is as follows: juli2, the second subscriber identity may be: juli 2.

In conjunction with the above-mentioned scene diagrams, the implementation of the location determination method of the present disclosure is further explained by the embodiments shown in fig. 2 to fig. 3.

Fig. 2 is a flow chart illustrating a method of position determination according to an exemplary embodiment, which may be applied to a first terminal side, as shown in fig. 2, and which includes the following steps.

In step S201, the first terminal acquires altitude information of the first terminal.

The first terminal obtains altitude information of the first terminal in various implementations, which are exemplified as follows:

in a possible implementation manner, a sensor capable of measuring the altitude information of the first terminal may be arranged in the first terminal in advance, and then the first terminal may directly acquire the actual altitude information of the first terminal through the arranged sensor. In this implementation manner, the first terminal may send the real location information of the first terminal to the second terminal, so that the second terminal can accurately determine the location of the first user.

In a second possible implementation manner, the first user may set a fixed value in the first terminal in advance as the altitude information of the first terminal, for example, 10m or 20m, and so on, and then the first terminal may locally acquire the preset altitude information of the first terminal from the first terminal. In this implementation, the location information of the second user determined by the first terminal is obtained according to the fixed value, that is, the location information of the first user determined by the first terminal is the location information that the first user wants the other users to obtain, and may not be the true location information of the first user, and when the first user does not want the other users to obtain the true location information of the first user, the implementation can protect the privacy of the first user.

In a third possible implementation manner, the first user may set, in the first terminal, altitude information corresponding to each authorized object in advance, where the altitude information corresponding to different authorized objects may be the same or different, for example, it is assumed that the authorized objects include: user 1 to user 5, the first user setting: the altitude information corresponding to the users 1-2 is real altitude information, the altitude information corresponding to the users 3 and 4 is 10m, and the altitude information corresponding to the user 5 is 0 m; then, in this step, the second terminal may locally obtain preset altitude information corresponding to the first user from the second terminal, for example, the second user is user 1, in this step, the first terminal obtains the actual altitude information of the first terminal, the second user is user 3, in this step, the first terminal obtains the altitude information 10m corresponding to user 3, and so on. The third implementation mode combines the first implementation mode and the second implementation mode, so that each user can obtain the position information of the first user according to the intention of the first user, and only part of users can obtain the real position information of the first user, thereby protecting the privacy of the first user.

The first terminal may acquire altitude information of the first terminal according to a variety of triggering conditions, for example, the triggering may be triggered when the first terminal receives a request about location information sent by the second terminal, or may be automatically triggered periodically by the first terminal. And, the implementation method of the trigger condition is various, for example, if the trigger condition is triggered when the first terminal receives a request about the location information sent by the second terminal, a trigger button may be preset in the second terminal, the trigger button may be implemented by software, and when the second user clicks the trigger button, the second terminal sends the request about the location information to the first terminal, thereby triggering the first terminal to acquire the altitude information of the first terminal. In a possible implementation manner, when the embodiment is applied to an instant messaging tool of a terminal, the trigger button may be specifically disposed in the instant messaging tool, and the disclosure is not limited to the specific position of the setting. For example, if the triggering condition is that the first terminal periodically and automatically triggers, a triggering period for acquiring the altitude information may be set in the first terminal in advance, and accordingly, the first terminal may periodically acquire the altitude information of the first terminal according to the triggering period.

In step S202, the first terminal determines the location information of the first user according to the altitude information.

The implementation manner of the position information of the first user is various. For example, the location information of the first user may include altitude information of the first user; or, the position information of the first user may include the number of floors where the first user is located; alternatively, the location information of the first user may include: the location of the first user and the altitude information of the first user; alternatively, the location information of the first user may include: the location of the first user and the number of floors the first user is located on; and so on.

In combination with the implementation possibility of the above location information, the possible implementation of this step is as follows:

in a first possible implementation, if the location information of the first user includes altitude information of the first user; this step may include:

the first terminal determines altitude information of the first terminal itself as altitude information of the first user.

In a second possible implementation manner, if the location information of the first user includes the number of floors where the first user is located; this step may include:

the method comprises the steps that a first terminal obtains the floor height of a building where a first user is located;

Wherein the floor height may be used to indicate the floor height of each floor of the building in which the first user is located.

The floor height may be input into the first terminal by the first user, and in this case, the obtaining, by the first terminal, the floor height of the building where the first user is located may include: the first terminal acquires the floor height input by the first user as the floor height of a building where the first user is located;

alternatively, the floor height may be obtained by the first terminal from a server. At this time, the server may preset information of floor heights of different buildings, and the acquiring, by the first terminal, the floor height of the building where the first user is located may include: the first terminal acquires information of a building where the first user is located, the information of the building where the first user is located is sent to the server, the floor height sent by the server is received, and the floor height sent by the server is searched and obtained according to the information of the building where the first user is located. The information about the building in which the first user is located may be input into the first terminal by the first user, and the obtaining, by the first terminal, the information about the building in which the first user is located may include: the first terminal acquires the building information input by the first user as the information of the building where the first user is located.

In a third possible implementation manner, the location information of the first user may include a location and altitude information of the first user, and then in step S201, the first terminal obtains longitude and latitude information of the first terminal in addition to the altitude information, where this step may include:

the first terminal determines the location of the first user according to the latitude and longitude information of the first terminal;

The determining, by the first terminal, the location of the first user according to the longitude and latitude information of the first terminal may include:

and the first terminal sends the longitude and latitude information to a server and receives a place corresponding to the longitude and latitude information sent by the server. At this time, the server receives the longitude and latitude information, can search a place corresponding to the received longitude and latitude information, and sends the searched place to the first terminal.

Or, the latitude and longitude information of different locations may be set in the first terminal in advance, and the first terminal may directly find the location corresponding to the latitude and longitude information of the first terminal according to the information set in advance in the first terminal itself as the location where the first user is located.

In a fourth possible implementation manner, the location information of the first user may include a location where the first user is located and a floor number, and then in step S201, the first terminal obtains the longitude and latitude information of the first terminal in addition to the altitude information, where this step may include:

the first terminal acquires the floor height corresponding to the place;

and the first terminal determines the floor number of the first user according to the altitude information of the first terminal and the floor height corresponding to the place.

The implementation of determining, by the first terminal, the location of the first user according to the latitude and longitude information may refer to the related description in the third possible implementation manner, which is not described herein again.

The step of setting the floor height corresponding to the different location in the server in advance may include the step of the first terminal acquiring the floor height corresponding to the location:

Or, the layer heights corresponding to the different locations may be set in the first terminal in advance, and the first terminal may search for the layer height corresponding to the location of the first user according to information set in the first terminal itself in advance.

The location may be a building, a position on a street, etc. When the place is a building, the corresponding floor height can be the floor height of each floor of the building; when the place is a certain position on a certain street, the corresponding floor height can be default, and correspondingly, the determined floor number of the first user can be 1 or default and the like.

In step S203, the first terminal sends the location information of the first user to the second terminal when determining that the second user is an authorized object.

The authorization object refers to a user authorized to obtain the location information of the first user from the first terminal. The authorization object may be preset in the first terminal, specifically, all users may be set as the authorization object by default by the system, or a user that can be the authorization object may be set autonomously by the first user. Specifically, when the location determining method of the present disclosure is applied to an instant messenger, all users in the instant messenger of the first user who contact the first user may be set as authorized objects, or a part of all users in the instant messenger who contact the first user may be designated as authorized objects by the first user, for example, it is assumed that the instant messenger has user 1, user 2, …, and user 6 in michat; then, users 1 to 6 may all be set as authorization objects by default, or some users, such as user 1, user 3, and user 5, may be designated as authorization objects by the first user.

When the authorization object is preset, the user identifier of each authorized user may be stored in the first terminal in advance, and in this step, the first terminal may search whether the pre-stored user identifier includes the second user identifier, if the second user identifier is included, the first terminal determines that the second user is the authorization object, and if the second user identifier is not included, the first terminal determines that the second user is not the authorization object.

In this disclosure, if the first terminal determines that the second user is not an authorized object, the first terminal may not send the location information of the first user to the second terminal.

In this step, the first terminal may further set different authorization time periods for different authorization objects besides determining that the second user is an authorization object, and this step may further include: and the second terminal judges that the current time is in the authorization time period corresponding to the first user. For example, assume that the authorization period set for the second user is: 10 to 12 points, if the current time is 10: and 30, the current time is in the authorization time period corresponding to the second user, and if the current time is 9 points, the current time is not in the authorization time period corresponding to the second user. At this time, if the first terminal determines that the current time is not within the authorization time period corresponding to the second user, the first terminal may not send the location information of the first user to the second terminal.

In this embodiment, the first terminal acquires altitude information of the first terminal, determines position information of the first user according to the altitude information, and sends the position information of the first user to the second terminal when the second user is determined to be an authorized object, so that the position of the first user in a building is determined.

Fig. 3 is a flow chart illustrating another position determination method according to an exemplary embodiment, which may be applied to a second terminal side, as shown in fig. 3, and which includes the following steps.

In step S301, the second terminal receives the location information of the first user sent by the first terminal, where the location information is sent when the first terminal determines that the second user is an authorized object.

If the position information that the second terminal wants to display is the number of floors where the first user is located, and the position information of the first user received by the second terminal includes the altitude information of the first user, or the location and the altitude information of the first user, an implementation step may further be included between step S301 and step S302, where the second terminal determines the number of floors where the first user is located according to the altitude information of the first user, and updates the altitude information of the first user in the position information of the first user by using the number of floors where the first user is located, for example, in a possible implementation manner, step S301 and step S302 may include:

the second terminal calculates the number of floors where the first user is located according to the altitude information of the first user and the floor height;

The second terminal acquiring the floor height of the building where the first user is located may include:

the second terminal locally acquires the floor height of a building where the first user is located from the second terminal; or,

the second terminal acquires the altitude information of the second terminal and the number of floors where the second user is located, and calculates the floor height of the building where the first user is located according to the altitude information of the second terminal and the number of floors where the second user is located, specifically, the floor height can be equal to the altitude information of the second terminal/the number of floors where the second user is located.

The above is only one implementation method for the second terminal to determine the floor number of the first user according to the altitude information of the first user, and the specific implementation for the second terminal to determine the floor number of the first user according to the altitude information of the first user may also be implemented by referring to the method for the first terminal to determine the floor number of the first user according to the altitude information of the first user, which is described in step S202, and is not described in detail here.

In step S302, the second terminal displays the location information of the first user.

In this embodiment, the second terminal receives and displays the location information of the first user sent by the first terminal, so that the second terminal cooperates with the first terminal to determine the location information of the first user.

Fig. 4A is a flow diagram illustrating another location determination method in accordance with an example embodiment in which location information of a first user may include: the number of floors where the first user is located; the method is particularly suitable for the situation that the second user knows the building where the first user is located but does not know the specific position of the first user in the building, and the first terminal indicates the real position information of the first user to the second terminal.

Wherein, the step is an optional step.

In step S404, the first terminal receives a request of the second terminal for altitude information, determines whether the second user is an authorized object according to a second user identifier included in the request, and if it is determined that the second user is not the authorized object, performs step S405, and if it is determined that the second user is the authorized object, performs step S406.

Here, the implementation of this step may refer to the related description in step S203, which is not described herein again.

In step S405, the first terminal sends a request failure response to the second terminal, and the second terminal prompts to the second user that the request for altitude information fails according to the request failure response; the flow branches to end.

Wherein, the second terminal may prompt the second user that the request for altitude information fails, and the disclosure is not limited thereto. For example, the second user may be prompted by a prompt box or the like that the request for altitude information failed.

In step S406, the first terminal transmits the location information of the first user to the second terminal.

In step S407, the second terminal receives the location information of the first user.

Here, the implementation of this step may refer to the related description in step S301, and is not described here again.

In step S408, the second terminal displays the location information of the first user.

The second terminal specifically displays the location information of the first user, and the disclosure is not limited thereto.

In this embodiment, for example, the location information of the first user includes the number of floors where the first user is located, if the location information of the first user includes the altitude information of the first user, an implementation step of determining, by the second terminal, the number of floors where the first user is located according to the altitude information of the first user and updating the altitude information of the first user in the location information of the first user by using the number of floors where the first user is located may also be included between step S407 and step S408, and for concrete implementation, reference is made to the relevant description in step S301, which is not repeated herein.

In this embodiment, the first terminal obtains the altitude information of the first terminal, determines the location information of the first user according to the altitude information, and sends the location information of the first user to the second terminal when the second user is determined to be an authorized object, thereby determining the location of the first user in the building.

As shown in fig. 5A, the method includes the following steps.

In step S501, the first terminal acquires altitude information and latitude and longitude information of the first terminal itself.

In this embodiment, the first terminal may obtain the altitude information of the first terminal itself through the first implementation manner described in step S201.

Similar to the implementation of the first terminal in acquiring altitude information, when acquiring the longitude and latitude information of the first terminal, the first terminal may acquire the actual longitude and latitude information of the second terminal in a GPS or other manner. In this implementation manner, the second terminal may send the real location information of the second terminal to the second terminal, so that the second terminal can accurately determine the location where the first user is located.

In step S502, the first terminal determines the location information of the first user according to the altitude information and the latitude and longitude information of the first terminal.

In step S503, the second terminal sends a request for location information to the first terminal, the request including the second subscriber identity.

Wherein, the step is an optional step.

In step S504, the first terminal receives a request of the second terminal regarding altitude information and latitude and longitude information, determines whether the second user is an authorized object according to a second user identifier included in the request, and if it is determined that the second user is not the authorized object, performs step S505, and if it is determined that the second user is the authorized object, performs step S506.

In step S505, the first terminal sends a request failure response to the second terminal, and the second terminal prompts the second user that the request for altitude information fails according to the request failure response; the flow branches to end.

In step S506, the first terminal transmits the location information of the first user to the second terminal.

In step S507, the second terminal receives the location information of the first user.

In step S508, the second terminal obtains the floor height of the building where the first user is located, calculates the number of floors where the first user is located according to the altitude information of the first user and the floor height, and updates the altitude information of the first user in the position information of the first user using the number of floors where the first user is located.

In step S509, the second terminal displays the location information of the first user.

In this embodiment, the first terminal obtains the altitude information and the latitude and longitude information of the first terminal, determines the location information of the first user according to the altitude information and the latitude and longitude information, and sends the location information of the first user to the second terminal when the second user is determined to be an authorized object, so that the determination of the location of the first user in the building is realized.

Fig. 5B is a flow diagram illustrating another location determination method in accordance with an example embodiment in which location information of a first user may include: the location of the first user and the number of floors; the method is particularly suitable for the situation that the second user does not know the position of the first user at all, and the first terminal indicates the position information of the first user to the second terminal according to the preset information of the first user.

As shown in fig. 5B, the method includes the following steps.

In step S511, the second terminal sends a request for location information to the first terminal, the request including the second subscriber identity.

Wherein, the step is an optional step.

In step S512, the first terminal receives a request of the second terminal for altitude information and latitude and longitude information, determines whether the second user is an authorized object according to a second user identifier included in the request, and if the second user is not determined to be an authorized object, performs step S513, and if the second user is determined to be an authorized object, performs step S514.

In step S513, the first terminal sends a request failure response to the second terminal, and the second terminal prompts to the second user that the request for altitude information fails according to the request failure response; the flow branches to end.

In step S514, the first terminal obtains the altitude information and the latitude and longitude information of the first terminal according to the second user identifier.

In this embodiment, the first terminal obtaining the altitude information of the first terminal according to the second user identifier may be implemented by the second and third possible implementation manners described in step S201.

Similar to the altitude information obtained by the first terminal, the implementation of the first terminal obtaining the latitude and longitude information in this step is as follows:

in a first possible implementation manner, the first user may set longitude and latitude information of a certain specified building in the first terminal in advance as the longitude and latitude information of the first terminal, and then the first terminal may locally acquire the preset longitude and latitude information directly from the first terminal. In this implementation, the location information acquired by the first terminal and sent to the second terminal is determined according to the longitude and latitude information preset by the first user, that is, the location where the first user is located and acquired by the second terminal is a location where the first user wishes to indicate to other users, but may not be the actual location of the first user, and when the first user does not wish to acquire the actual location information of the first user, the implementation can protect the privacy of the first user.

In a second possible implementation manner, the first user may set, in the first terminal, longitude and latitude information corresponding to each authorized object in advance, where the longitude and latitude information corresponding to different authorized objects may be the same or different, for example, it is assumed that the authorized objects include: user 1 to user 5, the first user setting: the longitude and latitude information corresponding to the users 1-2 is real altitude information, the longitude and latitude information corresponding to the users 3 and 4 is longitude and latitude information of the building 1, and the longitude and latitude information corresponding to the user 5 is longitude and latitude information of the building 2; then, in this step, the first terminal may locally obtain, from the first terminal, the preset longitude and latitude information corresponding to the second user, for example, the second user is user 1, in this step, the first terminal obtains the true longitude and latitude information of the first terminal, the second user is user 3, in this step, the first terminal obtains the longitude and latitude information of the building 1, and the like. The second implementation manner enables each user to obtain the location of the first user according to the intention of the first user, and only part of the users can obtain the real position information of the first user, so that the privacy of the first user can be protected.

In step S515, the first terminal determines location information of the first user according to altitude information and longitude and latitude information of the first terminal.

In step S516, the first terminal sends the location information of the first user to the second terminal.

In step S517, the second terminal receives the location information of the first user.

In step S518, the second terminal displays the location information of the first user.

In this embodiment, taking the location information of the first user as an example, where the first user is located and the number of floors, if the location information of the first user includes the location and the altitude information of the first user, an implementation step may also be included between step S517 and step S518, where the second terminal determines the number of floors where the first user is located according to the altitude information of the first user, and updates the altitude information of the first user in the location information of the first user by using the number of floors where the first user is located, for concrete implementation, refer to the relevant descriptions in step S508 and step S301, which is not described herein again.

In this embodiment, when the first terminal determines that the second user is an authorized object, the altitude information and the latitude and longitude information corresponding to the second user are obtained, the position information of the first user is determined according to the altitude information and the latitude and longitude information, and the position information of the first user is sent to the second terminal, so that the determination of the position of the first user in a building is realized.
