Abstract

The present disclosure relates to the field of short-distance wireless communications technologies, and in particular, to a method and system for obtaining location information of a target object, and an apparatus. In a solution of obtaining location information of a target object in the solutions, at least one second user is selected from a user relationship chain of a first user, and the location information of the target object is obtained by using a second terminal related to the second user. In another solution of obtaining location information of a target object, the location information of the target object is obtained by using a second terminal whose distance to a location represented by first location information is less than or equal to a preset distance.

a contact in a contact list, a user relationship chain in a communication application, or a user relationship chain in a social application.

2. The method according to claim 1, wherein the sending, by the first terminal, a search request to the second terminal respectively related to the at least one second user specifically comprises:

sending, by the first terminal, a first search request to a server, wherein the first search request carries the identifier of the target object, information about the at least one second user, and the first location information, and the first search request is used to instruct the server to send the search request to the second terminal respectively related to the at least one second user.

3. The method according to claim 1, after the sending, by the first terminal, the search request, and before the receiving the second location information, further comprising:

sending, by the first terminal, voice information to the second terminal, and receiving voice information fed back by the second terminal.

4. The first terminal according to claim 1, wherein the receiver is further configured to:

receive the second location information that is presented on a map and that is returned by the second terminal.

5. The first terminal according to claim 1, wherein the transmitter is further configured to:

send voice information to the second terminal, and receiving voice information fed back by the second terminal.

6. A method for obtaining location information of a target object, comprising:

receiving, by a second terminal, a search request, wherein the search request carries an identifier of a target object and first location information, and the first location information is a location at which the first terminal is located when a connection between a first terminal and the target object is disrupted;

sending, by the second terminal, a first broadcast message carrying the identifier of the target object when determining that a distance between a location at which the second terminal is located and the location represented by the first location information is less than or equal to a first threshold;

displaying, by the second terminal on a screen in real time, the location at which the second terminal is currently located, the location represented by the first location information, and the distance between the location at which the second terminal is currently located and the location represented by the first location information;

requesting, by the second terminal, to establish a connection to the target object when detecting a second broadcast message sent by the target object; and

returning, by the second terminal, second location information to the first terminal after the connection to the target object is established, wherein the second location information is a location at which the second terminal is located when the connection between the second terminal and the target object is established.

7. The method according to claim 6, wherein the receiving, by the second terminal, the search request specifically comprises:

receiving, by the second terminal, the search request sent by the first terminal or a server.

8. The method according to claim 6, after the displaying, by the second terminal on a screen in real time, the location at which the second terminal is currently located, the location represented by the first location information, and the distance, further comprising:

if the distance between the location at which the second terminal is currently located and the location represented by the first location information is greater than a second threshold, displaying, by the second terminal on the screen, an operational option that triggers sending of the first broadcast message, wherein the first threshold is greater than the second threshold; and

the sending, by the second terminal, a first broadcast message carrying the identifier of the target object specifically comprises;

sending, by the second terminal, the first broadcast message when the second terminal detects that the operational option is triggered.

9. The method according to claim 6, wherein if the distance between the location at which the second terminal is currently located and the location represented by the first location information is less than or equal to a second threshold, wherein the first threshold is greater than the second threshold,

the sending, by the second terminal, a first broadcast message carrying the identifier of the target object specifically comprises:

sending, by the second terminal, the first broadcast message directly.

10. A first terminal, comprising:

a memory comprising instructions;

a processor communication with the memory wherein the processor executes the instructions to;

obtain first location information of a target object, wherein the first location information is a location at which the first terminal is located when a connection between the first terminal and the target object is disrupted;
