It should be noted that the information obtaining method provided in the embodiment of the present application may be executed by the

intelligent terminals

101 and 102, or may be executed by the server 103.

The server 103 may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as a plurality of software or software modules (for example, to provide distributed services), or may be implemented as a single software or software module, and is not limited specifically herein.

It should be understood that the number of intelligent terminals, networks, and servers in fig. 1 is illustrative only. There may be any suitable number of intelligent terminals, networks, and servers, as desired for implementation.

With continued reference to fig. 2, a flow 200 of one embodiment of an information acquisition method for a first user equipment according to the present application is shown. The information acquisition method for the first user equipment comprises the following steps:

Step 201, receiving an instruction sent by the server, where the instruction includes a location information obtaining request, and the location information obtaining request includes identification information of the second user equipment.

In this embodiment, the first user device (i.e., a lost device, which may be, for example, the

smart terminal

101 or 102 shown in fig. 1) may set/store an identification information set of the trusted user device in advance (for example, before the first user device is lost), where the identification information set of the trusted user device includes identification information of at least one trusted user device. And the identification information in the identification information set is used for identifying the credit granting user equipment. The Identification information may be a device Identification (for example, IMSI (International Mobile Subscriber identity) of the user Equipment itself, IMEI (International Mobile Equipment identity), or may be a SIM card Identification (for example, a telephone Number) of a SIM card installed in the user Equipment.

Here, the trusted user equipment may refer to a device trusted by the first user equipment. For example, the first user device may only respond to requests from the trusted user device (or requests containing identification information of the trusted user device), thereby ensuring that instructions are only responded to when necessary (e.g., when the first user device is lost), avoiding information leakage or increasing system expense.

The first user equipment (for example, the

intelligent terminal

101 or 102 shown in fig. 1) may receive an instruction sent by a server (for example, the server 103 shown in fig. 1), where the instruction includes a location information obtaining request. The location information obtaining request may include identification information of a second user equipment (an intelligent terminal different from the first user equipment). Here, the instruction may be received by the server from the second user equipment, or the instruction may be generated by the server based on a request of the second user equipment (for example, a device search request for searching the first user equipment).

Step 202, it is determined whether the identification information of the second user equipment matches with the identification information in the identification information set.

In this embodiment, the first user equipment (for example, the

smart terminal

101 or 102 shown in fig. 1) may match the identification information of the second user equipment included in the location information request with the identification information in the identification information set of the trusted user equipment stored in the first user equipment, and determine whether the identification information of the second user equipment matches the identification information in the identification information set.

Here, that the identification information of the second user equipment matches with the identification information in the identification information set may mean that the identification information set includes identification information that is the same as the identification information of the second user equipment, or may mean that the identification information set includes identification information that is substantially the same as the identification information of the second user equipment (e.g., the same key information). For example, if the identification information of the second user equipment is 008613800000000 and 13800000000 identification information exists in the set of identification information, it may be determined that the identification information of the second user equipment matches the identification information in the set of identification information.

Step 203, in response to determining that the identification information of the second user equipment matches the identification information in the identification information set, sending the location information of the first user equipment to the server.

In this embodiment, the first user device (for example, the

smart terminal

101 or 102 shown in fig. 1) may send the location information of the first user device to the server if the identification information of the second user device matches the identification information in the identification information set (further, the location information of the first user device may be sent to the second user device by the server). Here, the location information of the first user equipment is used to determine a specific location of the first user equipment in order to retrieve the first user equipment.

Here, the location information may be a geographical coordinate value, for example, (48 ° 51'40 "N, 2 ° 20' 09" E). The location information may also be a detailed address, for example, XX street XX building 1 unit 301 room.

In the embodiment, the server performs data communication with the first user equipment to acquire the position information of the first user equipment, and the call or short message function of the first user equipment is not relied on. Therefore, when the lost device (i.e. the first user device) cannot perform communication services such as conversation or short messages (for example, when the SIM card is not installed), the position of the lost device can also be determined, so that the probability of acquiring the position information of the lost device is improved, and the lost device can be found back more easily.

In some optional implementations of this embodiment, the location information of the first user equipment may include outdoor location information of the first user equipment.

In some optional implementations of this embodiment, the location information of the first user equipment may be obtained by the first user equipment periodically (e.g., every predetermined period of time). For example, in step 203, the first user equipment directly transmits the periodically acquired location information of the first user equipment to the server without acquiring the location information of the first user equipment.

In some optional implementation manners of this embodiment, before sending the location information of the first user equipment to the server, the first user equipment may first obtain the location information of the first user equipment. Since the position of the first user equipment may change, the position information is acquired before the position information is sent, and the real-time performance and the accuracy of the position information of the first user equipment can be ensured.

The outdoor location information of the first user equipment may be acquired in various ways. For example, in a state where the location information service is turned on, the location information of the first user equipment is acquired through the GPS. Or, in a state that the location information service is not turned on, the location information of the first user equipment is acquired through the base station or the Wi-Fi.

In addition, in a state that the location information service is turned on, the first user equipment may also turn on the location information service first, and then acquire the location information of the first user equipment through the GPS.

It should be noted that the various manners of acquiring the outdoor location information are well-known technologies that are widely researched and applied at present, and are not described herein again.

In some optional implementations of this embodiment, the location information of the first user equipment may include outdoor location information of the first user equipment and indoor location information of the first user equipment.

In some optional implementations of this embodiment, before sending the location information of the first user equipment to the server, the first user equipment may first obtain indoor location information and outdoor location information of the first user equipment. By obtaining the indoor location information of the first user device, the location of the first user device may be able to be determined more accurately, thereby making it easier to find and find the first user device when the first user device is closer to the second user device (e.g., in the same room or in the same car, etc.).

The indoor location information of the first user equipment may also be obtained in various ways. For example, the indoor location information of the first user equipment is acquired through bluetooth (e.g., iBeacon technology), infrared ray, RFID (Radio Frequency Identification), ZigBee technology, ultrasonic wave, or the like.

It should be understood that the obtaining order of the indoor location information of the first user equipment and the outdoor location information of the first user equipment may be set according to the needs of an actual application scenario, and this is not specifically limited in this application. For example, the indoor location information of the first user equipment and the outdoor location information of the first user equipment may be sequentially acquired, or the indoor location information of the first user equipment and the outdoor location information of the first user equipment may be simultaneously acquired.

In some optional implementations of this embodiment, the instruction further includes an early warning instruction. The information acquisition method for the first user equipment further comprises the following steps: in response to determining that the identification information of the second user equipment is matched with the identification information in the identification information set, executing the early warning instruction, where the early warning instruction includes at least one of the following early warning operations: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

In practice, the intelligent terminal is light and thin in size, can be conveniently placed in a pocket or a bag, and is not easy to find. In addition, when the first user equipment is determined to be located in a public place with dense people flow, certain difficulty is brought to searching for the first user equipment. The early warning operations such as ringing, vibrating, flashing and the like with the maximum volume are executed, so that the user can be helped to quickly determine the specific position of the first user equipment, and the first user equipment can be retrieved conveniently.

In addition, due to the needs of the user in work and life, the smart terminal is not usually set to sound with the maximum volume, for example, the smart terminal may be in a vibration mode or a mute mode. Or the intelligent terminal does not turn on a flash lamp and the like. Therefore, in order to perform the above-described warning operation, it is necessary to set the first user equipment to the maximum volume, turn on the vibration, turn on the flash, and the like.

In some optional implementation manners of this embodiment, before executing the warning instruction, the information obtaining method for the first user equipment may further include: in response to determining that the ring volume of the first user device is not the maximum volume, setting the ring volume of the first user device to the maximum volume.

In some optional implementation manners of this embodiment, before executing the warning instruction, the information obtaining method for the first user equipment may further include: and in response to determining that the first user equipment does not turn on vibration, setting the first user equipment to a turn on vibration state.

In some optional implementation manners of this embodiment, before executing the warning instruction, the information obtaining method for the first user equipment may further include: and in response to determining that the flash of the first user equipment is not turned on, setting the flash of the first user equipment to an on state.

It should be noted that although the present embodiment describes that the warning instruction is executed in a manner of ringing, vibrating, and flashing a flash at the maximum sound volume, the present application is not limited thereto. It should be understood that the warning instruction may be performed in other manners as long as it can attract the attention of the user (to facilitate finding the first user equipment), and those skilled in the art can set the warning instruction according to the needs of the actual application scenario.

In some optional implementations of this embodiment, the set of identification information includes at least one phone number. The information acquisition method for the first user equipment further comprises the following steps: determining whether an incoming call number is included in at least one phone number in response to receiving the incoming call; in response to determining that the incoming call number is included in the at least one telephone number, determining whether the incoming call meets a preset condition; in response to determining that the incoming call meets the preset condition, performing at least one of the following early warning operations: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

Referring specifically to FIG. 3, a timing diagram of an alternative implementation of the embodiment shown in FIG. 2 is shown.

In fig. 3, the first user equipment is equipped with a SIM card (i.e., capable of performing communication services such as conversation and short message), and the set of identification information of the credit granting user equipment stored in the first user equipment includes at least one phone number.

In step 301, a first user device receives an incoming call (e.g., an incoming call from a second user device).

In step 302, the first user equipment determines whether the incoming call number is included in the at least one telephone number. If the incoming call number is contained in the at least one telephone number, the calling device (for example, the second user device) is the credit granting user device of the first user device. And if the incoming call number is not contained in the at least one telephone number, the incoming call is indicated to be from the non-trusted user equipment.

In step 303, in response to determining that the incoming call number is included in the at least one phone number, the first user equipment determines whether the incoming call satisfies a preset condition (e.g., a ringing duration, a ringing number, etc.). If the incoming call meets the preset condition, it indicates that the incoming call can instruct the first user equipment to perform the operation of step 304 (i.e., the first user equipment may be in a lost state).

Here, the preset condition is to identify whether the incoming call is an incoming call instructing the first user equipment to perform an early warning operation, to be distinguished from an incoming call for a call. For example, in the case of a normal incoming call (incoming call for a call), the answering is usually performed within four rings, or hung up by the caller when there is no answering while ringing four times. Therefore, the preset condition may be set to ring five times or more. That is, when the trusted user equipment (e.g., the second user equipment) normally calls the first user equipment, the ringing frequency is controlled within four times (answering or actively hanging up); and when the trusted user equipment (for example, the second user equipment) searches for the first user equipment, controlling the ringing frequency to be five times or more. In this way, the first user equipment can recognize an incoming call from the trusted user equipment (e.g., the second user equipment), so that corresponding subsequent operations can be performed.

Although it is described in the present embodiment that an incoming call is identified by the number of rings, the present application is not limited thereto. It should be understood that the incoming call may also be identified by other suitable means (e.g., waiting time, etc.), as long as the incoming call for finding the first user equipment can be distinguished from the incoming call for talking, and those skilled in the art can set the incoming call according to the needs of the actual application scenario.

In step 304, in response to determining that the incoming call meets a preset condition (e.g., rings five times), at least one of the following alerting operations is performed: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

Optionally, in response to determining that the incoming call meets a preset condition (e.g., rings five times), the location information of the first user equipment is sent to the trusted user equipment (e.g., sent to the second user equipment in a short message manner). The location information of the first user equipment may be acquired in a manner referring to the foregoing description about the outdoor location information and/or the indoor location information of the first user equipment.

In this implementation manner, the first user equipment (or the lost device) performs the early warning operation by judging whether the incoming call meets the preset condition and executing the early warning operation when the incoming call meets the preset condition, without depending on the communication connection between the first user equipment and the server, so that the early warning operation (or returning the location information of the first user equipment) can still be performed when the communication connection between the first user equipment and the server fails, thereby facilitating the retrieval of the first user equipment.

In some optional implementations of this embodiment, the set of identification information includes at least one phone number. The information acquisition method for the first user equipment further comprises the following steps: determining whether a short message transmission number is included in at least one phone number in response to receiving the short message; in response to determining that the short message sending number is contained in at least one telephone number, determining whether the short message contains a preset instruction; in response to determining that the short message contains the preset instruction, executing at least one of the following early warning operations: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

This implementation is described in detail below with reference to fig. 4. Fig. 4 shows a timing diagram of another alternative implementation of the embodiment shown in fig. 2.

In fig. 4, the first user equipment is equipped with a SIM card (i.e., capable of performing communication services such as conversation and short message), and the set of identification information of the credit granting user equipment stored in the first user equipment includes at least one phone number.

In step 401, a first user equipment receives a short message (e.g., a short message from a second user equipment).

In step 402, the first user equipment determines whether the sms sending number is included in the at least one phone number. If the short message sending number is contained in the at least one telephone number, the short message sending equipment (for example, the second user equipment) is the credit granting user equipment of the first user equipment. If the short message sending number is not contained in the at least one telephone number, the short message is from the non-credit user equipment.

In step 403, in response to determining that the short message sending number is included in the at least one phone number, the first user equipment determines whether the short message includes a preset instruction (e.g., an early warning instruction, etc.). If the short message contains a preset instruction, it indicates that the short message may instruct the first user equipment to perform the operation of step 404 (i.e., the first user equipment may be in a lost state). Here, the preset instruction is used to identify whether the short message is a short message instructing the first user equipment to perform an early warning operation, so as to distinguish the short message from a normal short message.

In step 404, in response to determining that the short message includes a preset instruction (e.g., an early warning instruction), at least one of the following early warning operations is performed: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

Optionally, in response to determining that the short message includes a preset instruction (e.g., an early warning instruction), the location information of the first user equipment is sent to the credit granting user equipment (e.g., sent to the second user equipment in a short message manner). The location information of the first user equipment may be acquired in a manner referring to the foregoing description about the outdoor location information and/or the indoor location information of the first user equipment.

In this implementation manner, the first user equipment (or the lost device) performs the early warning operation by judging whether the short message includes the preset instruction or not and executing the early warning operation when the short message includes the preset instruction, without depending on the communication connection between the first user equipment and the server, so that the early warning operation (or returning the location information of the first user equipment) can still be performed when the communication connection between the first user equipment and the server fails, thereby facilitating the retrieval of the first user equipment.

With continued reference to fig. 5, an application scenario of the information acquisition method for the first user equipment according to the present application is shown. In the application scenario 500 of fig. 5, the handset 501 is a lost device, the phone number of the handset 501 is 13800000005, and the handset 501 stores identification information thereon: {13800000001, 13800000002, 13800000003}. The user 504 sends an instruction including a device-finding request to the server 503 through the handset 502 (phone number 13800000002) to find the handset 501 (e.g., the phone number 13800000005 of the handset 501 is included in the device-finding request). After receiving the device search request, the server 503 transmits a location information acquisition request to the mobile phone 501, where the location information acquisition request includes the phone number 13800000002 of the mobile phone 502. After receiving the location information acquisition request, the mobile phone 501 first determines that the phone number 13800000002 in the location information acquisition request is included in the identification information set stored in the mobile phone 501, and then returns the geographic coordinate value (48 ° 51'40 "N, 2 ° 20' 09" E) of the mobile phone 501 to the server 503. The server 503 transmits the geographic coordinate value of the mobile phone 501 to the mobile phone 502, thereby implementing the determination of the specific location of the mobile phone 501.

In the information obtaining method for the first user equipment provided in the above embodiment of the present application, by receiving an instruction of a location information obtaining request including identification information of the second user equipment sent by the server, then determining whether the identification information of the second user equipment matches with identification information in an identification information set of the credit granting user equipment, and then sending the location information of the first user equipment to the server when matching, the location of the first user equipment can be determined, which is beneficial to finding back the first user equipment.

With further reference to FIG. 6, a flow 600 of one embodiment of an information acquisition method for a server is shown. The process 600 of the information obtaining method for the server includes the following steps:

step 601, receiving a device search request from the second user equipment, where the device search request includes the identification information of the second user equipment and the identification information of the first user equipment.

In this embodiment, a server (e.g., server 103 shown in fig. 1) may receive a device-finding request for finding a first user device from a second user device. The device search request comprises identification information of the first user device and identification information of the second user device.

Here, the Identification information may be a device Identification (for example, IMSI (International Mobile Subscriber identity Number), IMEI (International Mobile Equipment identity) or the like) of the user Equipment itself, or may be a SIM card Identification (for example, a telephone Number) of a SIM card installed in the user Equipment.

Step 602, based on the identification information of the first user equipment, sending an instruction including a location information obtaining request to the first user equipment, where the location information obtaining request includes identification information of the second user equipment.

In this embodiment, a server (e.g., the server 103 shown in fig. 1) may send an instruction including a location information obtaining request to the first user equipment indicated by the identification information of the first user equipment, so as to obtain the location information of the first user equipment. The instruction may be generated by the server in response to a device search request sent by the second user equipment, where the location information acquisition request includes identification information of the second user equipment.

In some optional implementations of this embodiment, step 602 may include: the server may first look up (to establish a communication connection with) the first user device based on the identification information of the first user device; and then transmits a location information acquisition request to the first user equipment.

In some optional implementations of this embodiment, step 602 may include: the server searches the first user equipment based on the identification information of the first user equipment, and acquires an identification information set which is backed up on the server and is the same as the identification information set of the credit granting user equipment stored on the first user equipment; determining whether the identification information of the second user equipment is matched with the identification information in the acquired identification information set; in response to determining that the identification information of the second user equipment matches the identification information in the acquired set of identification information, an instruction comprising a location information acquisition request is sent to the first user equipment.

Here, the fact that the identification information of the second user equipment matches the identification information in the identification information set may mean that the identification information same as the identification information of the second user equipment exists in the identification information set, or may mean that the identification information substantially the same as the identification information of the second user equipment (for example, the same key information) exists in the identification information set. For example, if the identification information of the second user equipment is 008613800000000 and 13800000000 identification information exists in the identification information set, it may be determined that the identification information of the second user equipment matches the identification information in the identification information set.

This implementation has the advantage that by the server determining that the identification information of the second user equipment matches the identification information of the acquired set of identification information and sending an instruction comprising a location information acquisition request to the first user equipment upon matching, the matching process can be moved from the first user equipment to the server, thereby reducing the number of times the first user equipment is requested and also reducing the number of interactions of the server with the first user equipment.

Step 603, receiving location information of the first user equipment from the first user equipment, where the location information of the first user equipment is sent by the first user equipment under the condition that the identification information of the second user equipment matches with the identification information in the identification information set of the credit granting user equipment stored on the first user equipment.

In this embodiment, a server (e.g., server 103 shown in fig. 1) may receive location information of a first user device from the first user device. The location information of the first user equipment may be sent to the server by the first user equipment when it is determined that the identification information of the second user equipment in the location information acquisition request matches an identification information set in an identification information set of the credit granting user equipment stored in the first user equipment. The identification information set comprises identification information of at least one trusted user equipment. Here, the location information of the first user device may be used to determine a specific location of the first user device in order to retrieve the first user device.

The above position information may be a geographical coordinate value, for example, (48 ° 51'40 "N, 2 ° 20' 09" E). The location information may also be a detailed address, for example XX street XX building 1 unit 301 room.

The outdoor location information of the first user equipment may be acquired by the first user equipment in various ways. For example, in a state where the location information service is turned on, the first user equipment acquires location information of the first user equipment through a GPS. Or, in a state that the location information service is not turned on, the first user equipment acquires the location information of the first user equipment through the base station or the Wi-Fi.

In addition, in a state where the location information service of the first user equipment is turned on, the outdoor location information of the first user equipment may also be acquired by the first user equipment through a GPS after the location service information is turned on.

The indoor location information of the first user equipment may also be obtained by the first user equipment in various ways. For example, the first user equipment obtains the indoor location information of the first user equipment through bluetooth (for example, iBeacon technology), infrared rays, RFID (Radio Frequency Identification), ZigBee technology, ultrasonic waves, and the like.

By receiving the indoor location information of the first user device, the location of the first user device can be determined more accurately, thereby making it easier to find and find the first user device when the first user device is closer to the second user device (e.g., in the same room or in the same car, etc.).

In some optional implementation manners of this embodiment, the information obtaining method for the server further includes: and transmitting the position information of the first user equipment to the second user equipment.

In the information obtaining method for the server according to the above embodiment of the present application, a device search request for finding the first user device is received from the second user device, where the device search request includes the identification information of the first user device and the identification information of the second user device, then an instruction including the location information acquisition request is sent to the first user device, and finally the location information of the first user device, which is sent by the first user device when the identification information of the second user device matches the identification information in the identification information set stored in the first user device, is received, so that the location of the first user device can be determined, and it is beneficial to finding back the first user device.

With further reference to fig. 7, a flow 700 of one embodiment of an information acquisition method for a second user equipment is shown. The process 700 of the information obtaining method for the second user equipment includes the following steps:

step 701, sending a device search request to a server, where the device search request includes identification information of a second user device and identification information of a first user device.

In this embodiment, the second user equipment (e.g., the

smart terminal

101 or 102 shown in fig. 1) may send a device finding request to the server (e.g., the server 103 shown in fig. 1). The device search request comprises identification information of the first user device and identification information of the second user device.

Here, the Identification information may be a device Identification (for example, an IMSI (International Mobile Subscriber identity Number), an IMEI (International Mobile Equipment identity Number), or the like) of the user Equipment itself, or may be a SIM card Identification (for example, a telephone Number) of a SIM card installed in the user Equipment.

Wherein the server is configured to:

responding to a received equipment searching request, and sending an instruction to first user equipment, wherein the instruction comprises a position information acquisition request which comprises identification information of second user equipment;

and receiving position information of the first user equipment returned by the first user equipment, wherein the position information of the first user equipment is sent by the first user equipment under the condition that the identification information of the second user equipment is matched with the identification information in an identification information set of the credit granting user equipment stored on the first user equipment, and the identification information set comprises the identification information of at least one credit granting user equipment.

The specific implementation step of the server receiving the location information of the first device may refer to the description of the embodiment in fig. 6, and is not described herein again.

Step 702, receiving the location information of the first user equipment returned by the server.

In this embodiment, the second user equipment (for example, the

smart terminal

101 or 102 shown in fig. 1) may receive the location information of the first user equipment returned by the server.

In some optional implementations of the present application, the method further comprises: initiating a call to first user equipment according to a preset rule; and/or sending a short message to the first user equipment, wherein the short message comprises a preset instruction.

Optionally, when the identification information set of the trusted user equipment stored in the first user equipment includes at least one phone number (for example, a phone number of the second user equipment), the second user equipment may initiate a call to the first user equipment according to a preset rule (for example, ringing five times or more). When the first user equipment receives the incoming call, firstly, whether the incoming call number is contained in the at least one telephone number is determined, and if the incoming call number is contained, the calling equipment (namely, the second user equipment) is the credit granting user equipment of the first user equipment; the first user device then determines whether the incoming call meets preset conditions (e.g., ringing duration, ringing times, etc.), and if so, it indicates that the first user device may be in a lost state and needs to perform an early warning operation (e.g., ring at maximum volume, vibrate, flash a flash).

Optionally, when the identification information set of the credit granting user equipment stored in the first user equipment includes at least one phone number (for example, a phone number of a second user equipment), the second user equipment may send a short message to the first user equipment, where the short message may include a preset instruction (for example, the foregoing early warning instruction). When the first user equipment receives the short message, firstly, whether the short message sending number is contained in the at least one telephone number is determined, and if the short message sending number is contained, the short message sending equipment (namely, the second user equipment) is the credit granting user equipment of the first user equipment; then, the first user equipment determines whether the short message contains a preset instruction (for example, the above-mentioned warning instruction), and if so, it indicates that the first user equipment may be in a lost state and needs to perform a warning operation (for example, ringing at the maximum volume, vibrating, flashing a flash lamp).

In the information obtaining method for the second user terminal provided in the above embodiment of the present application, the device search request for searching the first user device is sent to the server, where the device search request includes the identification information of the first user device and the identification information of the second user device, and then the location information of the first user device returned by the server is received, so that the location of the first user device can be determined, and it is beneficial to finding back the first user device.

With continued reference to FIG. 8, a timing sequence 800 for one embodiment of an information acquisition system according to the present application is shown.

The information acquisition system of this embodiment may include a first user device, a second user device, and a server. The first user equipment is to-be-found user equipment, and an identification information set of the trusted user equipment is set/stored in the first user equipment in advance (for example, before the first user equipment is lost).

As shown in fig. 8, in step 801, the second user equipment sends a device finding request to the server.

In this embodiment, the second user device (e.g., the

smart terminal

101 or 102 shown in fig. 1) may send a device search request for searching the first user device (e.g., a lost device, a smart terminal different from the second user device) to the server (e.g., the server 103 shown in fig. 1). The device search request comprises identification information of the first user device and identification information of the second user device.

In step 802, the server sends an instruction to the first user device.

In this embodiment, a server (e.g., the server 103 shown in fig. 1) may send, in response to receiving the device finding request, an instruction including a location information obtaining request to a first user device (e.g., the

smart terminal

101 or 102 shown in fig. 1) for obtaining location information of the first user device. The instruction may be generated by the server in response to a device search request sent by the second user equipment, and the location information obtaining request includes identification information of the second user equipment.

In step 803, the first user equipment determines that the second user equipment is a trusted user equipment.

In this embodiment, a first user device (for example, the

intelligent terminal

101 or 102 shown in fig. 1) may match identification information of a second user device included in a location information request with identification information in an identification information set of a trusted user device stored on the first user device, determine whether the identification information of the second user device matches with identification information in the identification information set, and if so, may determine that the second user device is the trusted user device.

In step 804, the first user device sends location information of the first device to a server.

In this embodiment, a first user device (for example, the

smart terminal

101 or 102 shown in fig. 1) may send location information of the first user device to a server when a second user device is a trusted user device. Here, the location information of the first user equipment is used to determine a specific location of the first user equipment.

In some optional implementations of this embodiment, the location information of the first user equipment may be obtained by the first user equipment periodically (e.g., every predetermined period of time).

In some optional implementation manners of this embodiment, before sending the location information of the first user equipment to the server, the first user equipment may first obtain the location information of the first user equipment. The outdoor location information of the first user equipment may be acquired in various ways. For example, in a state where the location information service is turned on, the location information of the first user equipment is acquired through the GPS. Or, in a state that the location information service is not turned on, the location information of the first user equipment is acquired through the base station or the Wi-Fi.

In some optional implementations of this embodiment, the instruction further includes an early warning instruction. The first user equipment may further execute the early warning instruction in response to determining that the identification information of the second user equipment matches the identification information in the identification information set, where the early warning instruction includes at least one of the following early warning operations: ringing, vibrating and flashing the flash lamp at the maximum sound volume.

In step 805, the server transmits the location information of the first device to the second user equipment.

In this embodiment, a server (e.g., server 103 shown in fig. 1) may transmit location information of a first user equipment received from a first device to a second user equipment.

In this embodiment, the server performs data communication with the first user equipment to obtain the location information of the first user equipment, without depending on the call or short message function of the first user equipment. Therefore, when the lost device (namely the first user device) cannot perform communication services such as conversation or short messages (for example, when the SIM card is not installed), the position of the lost device can be determined, so that the probability of acquiring the position information of the lost device is improved, and the lost device can be found back more conveniently.

In some optional implementations of this embodiment, the set of identification information includes at least one telephone number.

Optionally, the second user equipment may initiate a call to the first user equipment according to a preset rule (for example, ringing five times or more). The first user equipment may first determine whether the incoming call number is included in the at least one phone number after receiving the incoming call, and if so, it indicates that the calling equipment (i.e., the second user equipment) is a trusted user equipment of the first user equipment; it is then determined whether the incoming call meets preset conditions (e.g., duration of ringing, number of rings, etc.), and if so, it indicates that the first user device may be in a lost state and that an early warning operation needs to be performed (e.g., ringing at maximum volume, vibrating, flashing a flash).

Optionally, the second user equipment may send a short message to the first user equipment, where the short message may include a preset instruction (for example, the foregoing early warning instruction). When the first user equipment receives the short message, firstly, determining whether the short message sending number is contained in the at least one telephone number, and if so, indicating that the short message sending equipment (namely, the second user equipment) is credit granting user equipment of the first user equipment; and then determining whether the short message contains a preset instruction (for example, the above warning instruction), and if so, indicating that the first user equipment may be in a lost state and needs to perform a warning operation (for example, ringing at the maximum volume, vibrating, flashing a flash lamp).

In some optional implementations of this embodiment, before sending the instruction to the first user equipment, the server may: firstly, searching first user equipment based on identification information of the first user equipment, and acquiring an identification information set which is backed up on a server and is the same as an identification information set of credit granting user equipment stored on the first user equipment; determining whether the identification information of the second user equipment is matched with the identification information in the acquired identification information set; in response to determining that the identification information of the second user equipment matches the identification information in the acquired set of identification information, an instruction comprising a location information acquisition request is sent to the first user equipment.

In the information acquisition system provided in the above embodiment of the present application, first, a device search request for searching for the first user device is sent to the server through the second user device, then, the server sends an instruction including the location information acquisition request to the first user device, and then, in a case where the second user device is a trusted user device of the first user device, the first user device returns the location information of the first user device to the server and then to the second user device, so that the location of the first user device can be determined, which is beneficial to finding back the first user device.
