The mobile terminal 100 may include a wireless communication unit 110, an a/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, and a power supply unit 190, etc. Fig. 1 illustrates a mobile terminal having various components, but it is to be understood that not all illustrated components are required to be implemented. More or fewer components may alternatively be implemented. Elements of the mobile terminal will be described in detail below.

The wireless communication unit 110 typically includes one or more components that allow radio communication between the mobile terminal 100 and a wireless communication system or network. For example, the wireless communication unit may include at least one of a mobile communication module 111, a wireless internet module 112, a short-range wireless communication module 113, and a location information module 114.

The mobile communication module 111 transmits and/or receives radio signals to and/or from at least one of a base station (e.g., access point, node B, etc.), an external terminal, and a server. Such radio signals may include voice call signals, video call signals, or various types of data transmitted and/or received according to text and/or multimedia messages.

The wireless internet module 112 supports wireless internet access of the mobile terminal. The module may be internally or externally coupled to the terminal. The wireless internet access technology to which the module relates may include Wibro (wireless broadband), Wimax (worldwide interoperability for microwave access), HSDPA (high speed downlink packet access), and the like.

The short range wireless communication module 113 is a module for supporting short range communication. Some examples of short-range communication technologies include WLAN (Wireless LAN) (Wi-Fi), Bluetooth^TMRadio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), zigbee^TMAnd Near Field Communication (NFC), among others.

The location information module 114 is a module for checking or acquiring location information of the mobile terminal. A typical example of the location information module 114 is a GPS (global positioning system), and according to the current technology, the location information module 114 calculates distance information and accurate time information from three or more satellites and applies triangulation to the calculated information, thereby accurately calculating three-dimensional current location information according to longitude, latitude, and altitude. Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the position information module 114 can calculate the speed information by continuously calculating the current position information in real time.

The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 122, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode. The processed image frames may be displayed on the display unit 151. The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone 122 may receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication module 112 in case of a phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.

The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal. The user input unit 130 allows a user to input various types of information, and may include a keyboard, dome sheet, touch pad (e.g., a touch-sensitive member that detects changes in resistance, pressure, capacitance, and the like due to being touched), scroll wheel, joystick, and the like. In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

The sensing unit 140 detects a current state of the mobile terminal 100 (e.g., an open or closed state of the mobile terminal 100), a position of the mobile terminal 100, presence or absence of contact (i.e., touch input) by a user with the mobile terminal 100, an orientation of the mobile terminal 100, acceleration or deceleration movement and direction of the mobile terminal 100, and the like, and generates a command or signal for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device.

The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The identification module may store various information for authenticating a user using the mobile terminal 100 and may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and the like. In addition, a device having an identification module (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.

In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal. Various command signals or power input from the cradle may be used as signals for recognizing whether the mobile terminal is accurately mounted on the cradle. The output unit 150 is configured to provide output signals (e.g., audio signals, video signals, alarm signals, vibration signals, etc.) in a visual, audio, and/or tactile manner. The output unit 150 may include a display unit 151, an audio output module 152, and the like.

The display unit 151 may display information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphical User Interface (GUI) related to a call or other communication (e.g., text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display unit 151 may display a captured image and/or a received image, a UI or GUI displaying a video or an image and related functions, and the like.

Meanwhile, when the display unit 151 and the touch pad are overlapped with each other in the form of a layer to form a touch screen, the display unit 151 may serve as an input device and an output device. The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a thin film transistor LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and the like. Some of these displays may be configured to be transparent to allow a user to view from the outside, which may be referred to as transparent displays, and a typical transparent display may be, for example, a TOLED (transparent organic light emitting diode) display or the like. Depending on the particular desired implementation, the mobile terminal 100 may include two or more display units (or other display devices), for example, the mobile terminal may include an external display unit (not shown) and an internal display unit (not shown). The touch screen may be used to detect a touch input pressure as well as a touch input position and a touch input area.

The audio output module 152 may convert audio data received by the wireless communication unit 110 or stored in the memory 160 into an audio signal and output as sound when the mobile terminal is in a call signal reception mode, a call mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Also, the audio output module 152 may provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and the like.

The memory 160 may store software programs and the like for processing and controlling operations performed by the controller 180, for example, may store software programs implementing the navigation method of the present invention, or may temporarily store data (e.g., a phonebook, messages, still images, videos, and the like) that has been output or is to be output.

Based on the above mobile terminal hardware structure, various embodiments of the navigation device of the present invention are provided.

With combined reference to fig. 1 and 2, in a first embodiment of the navigation device of the present invention, the navigation device includes:

the first obtaining module 10 is configured to send a first mobile network search request to a searched wireless hotspot in a short-distance wireless communication manner when detecting that the mobile terminal is located in a base station coverage blind area, and receive mobile network signal strength and position information of each other terminal connected to the wireless hotspot, which are returned by the wireless hotspot;

a first determining module 20, configured to determine, based on the received signal strength of each mobile network and corresponding location information, that the signal strength of the mobile network is located in a location within a first preset strength interval, where a location closest to the mobile terminal is a target location of a coverage area of the base station, or determine that the location closest to the mobile terminal is located in a location within a preset distance interval, where a location with the largest signal strength of the mobile network is a target location of a coverage area of the base station;

a navigation module 30, configured to calculate a navigation path for the mobile terminal to reach the target location, and output the calculated navigation path at the mobile terminal;

when the wireless hotspot receives the first mobile network search request, the received first mobile network search request is forwarded to other terminals connected to the wireless hotspot, so that the other terminals can return the signal intensity and the position information of the mobile network to the wireless hotspot.

It should be noted that the main idea of the present invention is to help a mobile terminal user in a coverage blind area of a base station to find a coverage area of the base station, and the main scheme is as follows: when the mobile terminal is detected to be positioned in the base station coverage blind area, a mobile network searching request is sent to the searched wireless hotspot, and the mobile network signal strength and the position information which are returned by the wireless hotspot and are connected to the wireless hotspot are received, so that the target position of the base station coverage area is determined based on the received mobile network signal strength and the corresponding position information, the navigation path of the mobile terminal reaching the target position is further calculated, output is carried out, the mobile terminal user is guided to find the base station coverage area, and normal use of the mobile terminal is ensured.

In the embodiment of the present invention, the first obtaining module 10 first detects whether the mobile terminal is located in the coverage blind area of the base station, and in the specific implementation, as shown in fig. 3, a function control "mobile network signal search control" for triggering and searching for the coverage area of the base station may be set in a setting interface of the mobile terminal, and when the mobile network signal search control is triggered, the first obtaining module 10 detects that the mobile terminal is located in the coverage blind area of the base station.

Or, the first obtaining module 10 detects the mobile network signal strength of the mobile terminal, specifically, the first obtaining module 10 detects the mobile network signal strength of the mobile terminal through the mobile communication module 111 of the mobile terminal; after the mobile network signal strength of the mobile terminal is detected, comparing the mobile network signal strength with a preset mobile network signal strength, wherein the preset mobile network signal strength is the minimum mobile network signal strength of the mobile terminal capable of obtaining the mobile network service and is stored in the memory 160 of the mobile terminal in advance; when the mobile network signal intensity of the mobile terminal is identified to be smaller than the preset mobile network signal intensity, it is determined that the mobile terminal cannot normally obtain the mobile network service, and the mobile terminal is detected to be located in a coverage blind area of the base station.

When detecting that the mobile terminal is in a base station coverage blind area, the first obtaining module 10 starts a short-range wireless function of the mobile terminal through the short-range wireless communication module 113 of the mobile terminal, searches nearby wireless hotspots, and the wireless hotspots which can be searched corresponding to the type of the short-range wireless communication module 113 include Wi-Fi hotspots, bluetooth hotspots, and the like. Meanwhile, a first mobile network search request is constructed, and the first mobile network search request carries the MAC address of the mobile terminal.

After the wireless hotspot is searched, the first obtaining module 10 instructs the short-range wireless communication module 113 of the mobile terminal to establish a short-range wireless communication connection with the searched wireless hotspot, so as to send the constructed first mobile network search request to the searched wireless hotspot through the established short-range wireless communication connection, and request the wireless hotspot to search for a coverage area of a base station.

After receiving the first mobile network search request sent by the first obtaining module 10, the wireless hotspot identifies that the mobile terminal where the first obtaining module 10 is located in a coverage blind area of the base station, and needs to search for a coverage area of the base station, and at this time, forwards the received first mobile network search request to other terminals connected to the wireless hotspot, except for the mobile terminal.

After receiving a first mobile network searching request sent by the wireless hotspot, other terminals acquire the signal strength and the position information of the mobile network and return the acquired mobile network signal request and the corresponding position information to the wireless hotspot.

After receiving the mobile network signal strength and the corresponding location information returned by the other terminals, the wireless hotspot returns the mobile network signal strength and the corresponding location information of each other terminal to the first obtaining module 10 through the established short-distance wireless communication connection. In specific implementation, the wireless hotspot directly sends the mobile network signal strength and the corresponding location information of each other terminal to the mobile terminal in a unicast manner by using the MAC address of the mobile terminal as a destination MAC address, and the mobile network signal strength and the corresponding location information are processed by the first obtaining module 10; or, the wireless hotspot broadcasts the mobile network signal strength and the corresponding location information of each other terminal into the local area network by using the MAC address of the mobile terminal as a destination MAC address in a broadcast manner, and each terminal in the local area recognizes whether the destination MAC address is the same as its own MAC address, if so, receives the signal strength and the corresponding location information of each other terminal that receives the wireless hotspot broadcast, otherwise, the mobile terminal does not receive the signal strength and the corresponding location information, which is easy to understand, and the mobile terminal processes the mobile network signal strength and the corresponding location information of each other terminal that receives the wireless hotspot broadcast by the first obtaining module 10.

Correspondingly, the first obtaining module 10 receives the mobile network signal strength and the corresponding location information of each other terminal connected to the wireless hotspot, which are returned by the wireless hotspot, and transmits the received mobile network signal strength and the corresponding location information to the first determining module 20 for processing.

For example, as shown in fig. 4, the first obtaining module 10 obtains the mobile network signal strength and the corresponding location information of each of the terminals 1 to 3 through the searched wireless hotspot.

After receiving the signal strength of each mobile network and the corresponding location information transmitted by the first obtaining module 10, the first determining module 20 performs sorting according to the strength or the distance from the mobile terminal, and determines that the signal strength of the mobile network is located in a first preset strength interval, where the location closest to the mobile terminal is a target location of a coverage area of the base station, or determines that the distance from the mobile terminal is located in a preset distance interval, where the location with the largest signal strength of the mobile network is a target location of a coverage area of the base station.

The first preset strength interval is a rising strength interval with a preset mobile network signal strength (i.e. the minimum mobile network signal strength at which the mobile terminal can obtain the mobile network service) as a starting point, and the preset distance interval is a rising distance interval with a preset distance value (the preset distance value can be set by the user as required, for example, if the user is willing to walk at most 1 km to find the coverage area of the base station, the preset distance value can be set to 1 km) as an end point.

Optionally, in an embodiment, the first determining module 20 determines, by default, based on the received signal strength of each mobile network and the corresponding location information, that the signal strength of the mobile network is located in a location within a first preset strength interval, where a location closest to the mobile terminal is a target location of a coverage area of the base station. In another embodiment, the first determining module 20 may determine the target location of the coverage area of the base station according to a determination manner set by a user.

After determining the target location of the coverage area of the base station, the first determination module 20 transmits the determined target location to the navigation module 30 for processing.

After receiving the target position transmitted by the first determining module 20, the navigation module 30 locates the mobile terminal through the position information module 114 of the mobile terminal to obtain the current position information of the mobile terminal, and after obtaining the current position information of the mobile terminal, calculates a navigation path of the mobile terminal to the target position by using a preset navigation algorithm based on the current position information of the mobile terminal. The navigation algorithm used in the present invention is not specifically limited, and can be selected by those skilled in the art according to actual needs.

After calculating the navigation path for the mobile terminal to reach the target position, the navigation module 30 outputs the calculated navigation path at the mobile terminal.

It should be noted that, in the embodiment of the present invention, a situation that a plurality of wireless hotspots may be searched in an actual application scenario is considered, and a scheme for acquiring the mobile network signal strength and the location information of the plurality of wireless hotspots is further provided.

In this embodiment of the present invention, after searching for a nearby wireless hotspot through the short-range wireless communication module 113 of the mobile terminal, if a plurality of wireless hotspots are searched, the first obtaining module 10 may perform sorting according to the hotspot names of the plurality of searched wireless hotspots, or perform sorting according to the short-range wireless signal strengths of the plurality of searched wireless hotspots (for example, sort according to the order of the short-range wireless signal strengths from large to small), or perform other sorting manners, which is not limited in this embodiment of the present invention.

After finishing sorting the searched wireless hotspots, the first obtaining module 10 selects one wireless hotspot of the searched wireless hotspots according to the sorting order, and when the wireless hotspot is selected, sends a first mobile network searching request to the selected wireless hotspot, and receives mobile network signal strength and position information of other terminals, which are returned by the selected wireless hotspot and connected to the selected wireless hotspot. The manner in which the first obtaining module 10 obtains the mobile network signal strength and the location information of the other terminal based on the wireless hotspot may refer to the related description of the first embodiment, and is not described herein again.

And after receiving the mobile network signal strength and the position information of each other terminal connected to the selected wireless hotspot, which are returned by the selected wireless hotspot, continuously selecting one wireless hotspot in the plurality of searched wireless hotspots until the plurality of searched wireless hotspots are all selected, so as to obtain the mobile network signal strength and the corresponding position information of each other terminal connected to each wireless hotspot, which are returned by each searched wireless hotspot.

For the processing performed by the first determining module 20, reference may be made to the related description of the first embodiment, and details are not repeated here.

For example, as shown in fig. 5, 5 wireless hotspots, from the wireless hotspot 1 to the wireless hotspot 5, are searched, and the first obtaining module 10 sequentially passes through the wireless hotspots 1 to the wireless hotspot 5 to obtain the mobile network signal strength and the corresponding location information of each of the terminals B to K.

Further, based on the first embodiment, a third embodiment of the navigation device of the present invention is proposed, in this embodiment, the navigation module 30 is further configured to obtain location information of the mobile terminal, and calculate a shortest path for the mobile terminal to reach the target location based on the location information; and the mobile terminal is also used for displaying a map interface on the mobile terminal and superposing the calculated shortest path on the map of the map interface to be displayed as a navigation path.

It should be noted that, in this embodiment, a manner of calculating a navigation path is further described on the basis of the first embodiment, and other references may be made to the first embodiment, which is not described herein again.

In the embodiment of the present invention, after receiving the target position transmitted by the first determining module 20, the navigation module 30 locates the mobile terminal through the position information module 114 of the mobile terminal, obtains the current position information of the mobile terminal, and after obtaining the current position information of the mobile terminal, based on the current position information of the mobile terminal, calculates a navigation path of the mobile terminal to the target position by using a preset navigation algorithm, determines a shortest path among the calculated navigation paths, and uses the shortest path as an output navigation path.

When the mobile network signal intensity of the mobile terminal is determined to be within a second preset intensity interval, the identification module sends indication information to the first sending module; and when the mobile network signal intensity of the mobile terminal is determined to be outside the second preset intensity interval, no processing is carried out.

After the first sending module receives the indication information sent by the identification module, the first sending module locates the mobile terminal through the location information module 114 of the mobile terminal to obtain the current location information of the mobile terminal, and after obtaining the current location information of the mobile terminal, the first sending module packages the location information of the mobile terminal and the mobile network signal strength together and returns the location information of the mobile terminal and the mobile network signal strength to the wireless hotspot, and the wireless hotspot forwards the location information to other terminals needing to be navigated to the coverage area of the base station.
