Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
First, an application scenario of the present disclosure is described, and the present disclosure may be applied to find a target terminal, where the target terminal may be a mobile phone (such as an Android mobile phone, an iOS mobile phone, etc.), a tablet computer, a shared bicycle, a Mobile Internet Device (MID), an intelligent water meter, and the like, and when the target terminal is found, it may be difficult to find the target terminal because of a large number of target terminals, poor network connection, or no Global Positioning System (GPS) module or the like. For example, when a user searches for a mobile phone, the position of the mobile phone is determined according to GPS positioning, which is based on positioning by combining a satellite in space with a triangulation principle, but if the environment where the mobile phone is located has too many shielding objects or exists indoors, the GPS positioning will be inaccurate, so that the user cannot search for the mobile phone.
In the prior art, a near field communication module is generally mounted on a target terminal, and the distance between the target terminal to be detected and a search terminal is determined according to the strength of a transmission signal.
For example, when a user searches for a shared bicycle to be used, the user opens a client or third-party software of the shared bicycle required to be used on a mobile phone, determines the position of the user by using a GPS positioning function, and establishes a short-range communication connection with the shared bicycle through short-range Wireless communication technologies such as Bluetooth (Bluetooth) or Wireless Fidelity (WIFI for short), wherein the closer the mobile phone is to the shared bicycle, the stronger the strength of the received short-range communication signal is; the farther the mobile phone is away from the shared bicycle, the weaker the intensity of the received close-range communication signal is, so that the position of the shared bicycle is judged. However, when there is an urban obstruction, the obstruction of the urban obstruction affects the transmission of electromagnetic waves, thereby affecting the transmission of transmission signals and causing poor distance judgment accuracy; secondly, the distance obtained through the signal strength is single-dimensional, direction information cannot be provided, a target terminal cannot be accurately searched, and the cost is high.
In order to solve the above problems, the present application provides a method, an apparatus, a storage medium, and an electronic device for finding a terminal. The method comprises the steps that a beacon signal which is received by a searching terminal and is sent by a target terminal according to a beacon request message is searched, wherein the beacon signal comprises the transmitting power of the target terminal for transmitting signals; the position of the target terminal is determined according to the transmitting power, so that the searching terminal obtains the distance and the direction of the target terminal by receiving and resolving the beacon signal transmitted by the target terminal, the position information of the target terminal can be obtained under the condition of not depending on network connection and positioning, the position information comprises the information of two dimensions of the distance and the direction, and the target terminal can be searched more accurately.
The present disclosure is described below with reference to specific examples.
Fig. 1 is a flowchart of a method for finding a terminal according to an embodiment of the present disclosure, as shown in fig. 1, and the method is applied to find a terminal, and includes:
s101, sending a beacon request message.
In this embodiment, the beacon request message may be transmitted in consideration of a network connection state with the target terminal by the following two implementation manners:
in a first mode, for the case that the network connection is normal, the beacon request message may include a beacon signal request instruction for requesting the target terminal to transmit the beacon signal, and the beacon signal request instruction may be periodically transmitted to the target terminal in the case that the network connection with the target terminal is normal, so that the beacon signal request instruction is directly transmitted to the target terminal in the case that the network connection is normal.
In a second mode, for the case of abnormal network connection, the beacon request message may include a beacon trigger signal, where the beacon trigger signal is used to trigger the target terminal to broadcast the beacon signal, and the beacon trigger signal may be periodically broadcast in the case of abnormal network connection with the target terminal, so that the beacon trigger signal is sent in a broadcast manner in the case of abnormal network connection.
Wherein, whether the network connection is normal can be determined by: the method comprises the steps that a search terminal sends a network connection test signal to a target terminal, the target terminal sends a connection response signal to the search terminal after receiving the network connection test signal, the search terminal determines that the network connection is normal after receiving the connection response signal sent by the target terminal in a preset time period, a beacon signal request instruction can be sent, if the preset time period is reached and the search terminal does not receive the connection response signal, the network connection is determined to be abnormal, and the beacon trigger signal can be broadcast periodically.
However, considering that the above manner needs to increase signaling interaction between the target terminal and the searching terminal, in another embodiment of the present disclosure, the searching terminal may first periodically send a beacon signal request instruction to the target terminal, and determine whether a request response message sent by the target terminal according to the beacon signal request instruction is received within a first preset time period, when the first preset time period is reached, if a receive response message sent by the terminal according to the beacon signal request message is not received, it indicates that a network connection is abnormal, at this time, a beacon trigger signal may be periodically broadcast, and if a receive response message sent by the terminal according to the beacon signal request message is received within the first preset time period, it indicates that the network connection between the searching terminal and the target terminal is normal, and the target terminal receives the beacon signal request instruction, at this time, a beacon signal broadcasted by the target terminal according to the beacon request message may be received. Therefore, whether the network connection state is normal can be determined by trying to send a beacon signal request instruction, and the beacon trigger signal is periodically broadcast under the condition that the network connection state is abnormal, so that a beacon request message can be flexibly sent according to the state of the network connection, and whether the network connection is normal does not need to be determined through an additionally sent network connection test signal, and the signaling overhead is reduced.
S102, receiving a beacon signal broadcasted by the target terminal according to the beacon request message when the target terminal receives the beacon request message.
In this embodiment, the target terminal may broadcast the beacon signal periodically when receiving the beacon request message, where the beacon signal may include a terminal identifier of the target terminal, so that the searching terminal knows the terminal that transmits the beacon signal according to the terminal identifier.
And S103, after receiving the beacon signal broadcast by the target terminal, determining the position of the target terminal according to the beacon signal.
The location of the target terminal may include a direction of the target terminal and a distance between the target terminal and the search terminal.
In a possible implementation manner, a direction-finding antenna array is arranged on a search terminal, the direction-finding antenna array may include at least two direction-finding antennas, when the search terminal receives a beacon signal transmitted by a target terminal, a receiving time difference existing when the beacon signal passes through any two direction-finding antennas is obtained, the receiving time difference may be a function of an incoming wave direction angle of beacon signal transmission, the receiving time difference is resolved to obtain the incoming wave direction angle of the beacon signal, so as to obtain a direction of the target terminal, and a distance between the target terminal and the search terminal is calculated by a multi-antenna triangular positioning method, so as to obtain a position of the target terminal according to the direction and the distance.
It should be noted that, the above-mentioned method for obtaining the direction of the target terminal through the beacon signal and the multi-antenna triangular positioning method may refer to implementation manners in related technologies, and are not described herein again.
By the method, the searching terminal obtains the distance and the direction of the target terminal by receiving and calculating the beacon signal sent by the target terminal, so that the position information of the target terminal can be obtained without depending on network connection and positioning, and the position information comprises information of two dimensions of the distance and the direction, so that the target terminal can be searched more accurately.
Fig. 2 is a flowchart of another method for finding a terminal according to an embodiment of the present disclosure, and as shown in fig. 2, the method is applied to a target terminal, and includes:
s201, receiving a beacon request message sent by a searching terminal.
In this step, the beacon request message may include a beacon signal request instruction, where the target terminal periodically receives the beacon signal request instruction sent by the querying terminal in case of successful network camping, and the beacon request message may further include a beacon trigger signal, and the target terminal may periodically detect the beacon trigger signal broadcast by the querying terminal in case of failed network camping.
It should be noted that, after the target terminal is powered on, a communication network for communication needs to be searched first, for example, the communication network may be an NBIoT network, and in the case that the communication network is searched, the target terminal registers in the communication network, so as to complete network camping, where a specific process of the target terminal performing network camping may refer to a process of the terminal performing network camping in the related art, and is not described herein again.
S202, broadcasting the beacon signal according to the beacon request message, so that the searching terminal determines the location of the target terminal according to the beacon signal after receiving the beacon signal.
The beacon signal may include a terminal identifier of a target terminal, and after the search terminal detects the beacon signal, the search terminal determines, through the terminal identifier, that the beacon signal is received, so as to determine the location of the target terminal according to the beacon signal.
According to the method, after the target terminal receives the beacon request message, the beacon signal is sent in a broadcast mode, the searching terminal obtains the distance and the direction of the target terminal by receiving and calculating the beacon signal sent by the target terminal, and therefore the position information of the target terminal can be obtained under the condition that network connection and positioning are not relied on, and the position information comprises information of two dimensions of the distance and the direction, so that the target terminal can be searched more accurately.
Fig. 3 is a flowchart of another method for finding a terminal according to an embodiment of the present disclosure, and as shown in fig. 3, the method includes:
s301, the searching terminal periodically sends a beacon signal request instruction to the target terminal.
The searching terminal may send a beacon signal request instruction to the target terminal at a first preset time interval.
S302, the searching terminal determines whether a request response message sent by the target terminal according to the beacon signal request instruction is received.
In this step, the target terminal periodically receives the beacon signal request instruction sent by the search terminal under the condition that the network residence is successful, if the beacon request instruction sent by the search terminal is received, a request response message responding to the beacon signal request instruction is sent to the search terminal, and the target terminal does not send the request response message under the condition that the network residence is failed.
Executing steps S303 and S306 when a reception response message sent by the terminal according to the beacon signal request instruction is received within a first preset time period;
and executing the steps S304 to S306 when the first preset time period is reached and a reception response message sent by the terminal according to the beacon signal request instruction is not received.
Here, since the connection state of the network may affect the transmission of the signal, that is, in the case that the network connection is normal, the signal sent by the signal sending end can be normally transmitted to the signal receiving end, therefore, in this step, it may be determined whether the network connection is normal by whether a response message to the beacon signal request instruction is received within a first preset time.
S303, searching the beacon signal broadcast by the terminal detection target terminal.
In this step, after sending the request response message to the search terminal, the target terminal may periodically broadcast a beacon signal, where the beacon signal includes a terminal identifier of the target terminal, so that the search terminal knows the terminal sending the beacon signal according to the terminal identifier.
S304, the searching terminal broadcasts the beacon trigger signal periodically.
The target terminal can periodically detect the beacon trigger signal broadcast by the search terminal under the condition of network residence failure, wherein the search terminal cannot receive a request response message sent by the target terminal under the condition of network residence failure of the target terminal, and at the moment, the search terminal sends the beacon trigger signal to the target terminal so as to trigger the target terminal to broadcast the beacon signal.
S305, the target terminal broadcasts the beacon signal according to the beacon trigger signal when receiving the beacon trigger signal.
It should be noted that the beacon signal request instruction or the beacon trigger signal may include a terminal identifier of the target terminal, a transmission period of the beacon trigger signal, a signal transmission power indicating that the target terminal broadcasts the beacon signal, and a time interval indicating that the target terminal broadcasts the beacon signal, so that the target terminal may continue to detect the beacon trigger signal sent by the target terminal according to a specified period after receiving the beacon trigger signal broadcasted by the target terminal, where the specified period may be an integral multiple of the transmission period of the beacon trigger signal, so that the beacon trigger signal does not need to be detected in real time, and the purpose of saving power is achieved.
Further, if the beacon trigger signal periodically broadcast by the search terminal is not received within a second preset time period, the broadcast of the beacon signal is stopped, here, after the beacon signal is broadcast, if the beacon signal periodically broadcast by the search terminal is not received within the second preset time period, it may be determined that the target terminal has exceeded the search range of the search terminal, or the process of searching for the target terminal is stopped, the target terminal may stop broadcasting the beacon signal, thereby saving the electric quantity of the target terminal.
In addition, the beacon trigger signal and the beacon signal may include the same frame structure, for example, an NPSS signal for time synchronization and acquisition and an NPBCH signal for transmitting a 36-bit payload may be included, which is only for illustration and is not limited herein.
S306, after the searching terminal receives the beacon signal broadcast by the target terminal, the position of the target terminal is determined according to the beacon signal.
In this embodiment, after the position of the target terminal is determined, the guidance information may be displayed, so as to guide the user to move to the position of the target terminal, and assist the user in quickly finding the target terminal.
For example, the guidance information may be voice prompt information, so as to guide the user to move to the target terminal through voice prompt, and the guidance information may also be marking information on a map, so as to mark the position of the target terminal on the map for finding a terminal exhibition, so as to facilitate the user to move to the target terminal.
It should be noted that, for the case that the target terminal receives the reception response message sent by the terminal according to the beacon signal request instruction within the first preset time period, considering that the target terminal periodically broadcasts the beacon signal and therefore needs to consume a large amount of power, and after the target terminal receives the beacon signal, the position of the target terminal can be determined according to the beacon signal, at this time, the target terminal consumes power if the target terminal continues to periodically broadcast the signal, in order to solve the problem, in another embodiment of the present disclosure, after the target terminal receives the beacon signal broadcast by the target terminal according to the beacon signal request instruction at the current period, the signal transmission power and/or the time interval can be adjusted, so as to reduce the power consumption of the target terminal and achieve the purpose of saving power.
Illustratively, the signal transmission power and/or the time interval may be adjusted by two implementations:
the first method is as follows: sending a parameter adjusting instruction to the target terminal, wherein the parameter adjusting instruction is used for instructing to reduce the signal transmission power of the beacon signal broadcast by the target terminal; and/or increasing the time interval of the beacon signal broadcast by the target terminal, so that the target terminal adjusts the signal transmission power and/or the time interval according to the parameter adjusting instruction.
Therefore, after the searching terminal sends the parameter adjusting instruction to the target terminal, the target terminal can broadcast the beacon signal according to the reduced signal transmitting power indicated in the parameter adjusting instruction and/or the increased time interval, and the aim of saving the electric quantity is fulfilled.
The second method comprises the following steps: in addition, in the mode, the signal transmission power and/or the time interval can be adjusted through multiplexing the beacon signal request instruction, extra signaling overhead is not needed to be added, and system resources are saved.
It should be noted that, the adjustment of the signal transmission power and/or the time interval may be adjusted according to a preset adjustment value, that is, the signal transmission power and/or the time interval may be increased or decreased by the preset adjustment value each time the signal transmission power and/or the time interval is adjusted.
In addition, in the process of the search terminal moving, the real-time distance between the search terminal and the target terminal can be detected, and the signal transmitting power and/or the time interval can be adjusted according to the change direction of the real-time distance relative to the terminal distance.
Illustratively, the direction of change may include an increase or a decrease, and in the case where the real-time distance increases relative to the target terminal distance, the signal transmission power may be increased; and/or, decreasing the time interval; reducing the signal transmission power under the condition that the real-time distance is reduced relative to the target terminal distance; and/or increasing the time interval. Therefore, the signal transmitting power and/or the time interval can be flexibly adjusted according to the real-time distance between the searching terminal and the target terminal, so that the electric quantity of the target terminal is saved when the searching terminal is closer to the target terminal, and the position information of the target terminal can be more accurately acquired when the searching terminal is farther away from the target terminal.
The above steps are described below in connection with an exemplary embodiment.
The search terminal may include a signal transmission module, a signal receiving and processing module, and a first communication module, the target terminal may include a second communication module, a detection module, and a beacon signal transmission module, the search terminal may periodically send a beacon signal request instruction to the target terminal through the first communication module, the target terminal searches for a target network through the second communication module, and after the target network is searched, the target terminal performs network camping.
Under the condition that the target terminal successfully camps on the network, a beacon signal request instruction sent by the searching terminal is periodically received through the second communication module, under the condition that the beacon signal request instruction sent by the searching terminal is received through the second communication module, a receiving response message is sent to the searching terminal through the second communication module, the beacon signal is periodically broadcasted, whether the searching terminal receives the receiving response message sent by the target terminal in a first preset time period or not is determined through the first communication module, after the first communication module receives the receiving response message, a signal receiving processing module of the searching terminal detects the beacon signal broadcasted by the second communication module of the target terminal, and after the beacon signal is detected, the position of the target terminal is determined according to the beacon signal.
