Detailed ways

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

In the existing technology, when a terminal device uses GNSS (Global Navigation Satellite System, Global Navigation Satellite System) for positioning, it can position normally in an environment with satellite signals. However, when it is in an environment without satellite signals for a long time, every time After the second positioning cycle, GNSS positioning will search for satellite signals for a long time, but the satellite signals cannot be obtained, resulting in positioning failure. This not only affects the positioning efficiency, but also increases the power consumption of the module and reduces the battery life of the terminal device. battery life. Therefore, the technical problem to be solved by this application is: how to improve the positioning efficiency of the terminal device.

In the embodiment of this application, the terminal device can be any form of electronic device that supports GNSS positioning and LBS positioning, such as smartphones, portable notebook computers, desktop computers, wearable devices, head-mounted devices, vehicle-mounted terminals, etc. This application does not place specific restrictions on the implementation form of the terminal device.

Please refer to FIG. 1 , which is a schematic flowchart of a positioning mode control method provided by an embodiment of the present application. This method can be applied to terminal devices. As shown in Figure 1, the method may include steps:

S101: Obtain the positioning status corresponding to the first positioning mode of the terminal device, and determine whether the positioning status is the first positioning status.

In some feasible implementations, the terminal device can obtain the positioning state corresponding to its first positioning mode and determine whether the positioning state is the first positioning state.

The positioning status corresponding to the first positioning mode may be used to indicate whether the terminal device searched for a positioning signal the last time it used the first positioning mode for positioning.

Optionally, the positioning state corresponding to the first positioning mode may include a first positioning state and a second positioning state. The first positioning state may be used to indicate that the terminal device was able to search for a positioning signal the last time it used the first positioning mode for positioning. The second positioning state may be used to indicate that the terminal device failed to search for satellite signals when the first positioning mode was used for positioning last time. For example, the first positioning state can be represented by a first preset value, and the second positioning state can be represented by a second preset value. For example, the first preset value can be 0, and the second preset value can be 1.

Optionally, the first positioning mode may be positioning based on GNSS (Global Navigation Satellite System, Global Navigation Satellite System).

S102. If the positioning state is the first positioning state, positioning is performed through the first positioning mode and a positioning signal is obtained.

In some feasible implementations, if the terminal device determines that the positioning state corresponding to its first positioning mode is the first positioning state, it can perform positioning and obtain the positioning signal through the first positioning mode.

Optionally, when the first positioning mode is GNSS-based positioning, after the terminal device determines that its positioning state is the first positioning state, positioning can be achieved through the GNSS positioning module in the terminal device, and further determines whether it can Obtain positioning signal. Specifically, if the terminal device determines that the GNSS positioning module outputs an indication message, it can be determined that the terminal device can obtain the positioning signal through the GNSS positioning module. If the terminal device determines that the GNSS positioning module does not output an indication message, it can be determined that the terminal device failed to obtain a positioning signal through the GNSS positioning module. The indication message may be used to indicate whether the terminal device can obtain the positioning signal through the GNSS positioning module.

It should be understood that it is more difficult to receive satellite signals in places with weak signal coverage such as indoors and tunnels. Being located in urban areas, high buildings or shelters may also affect satellite signal reception. Or, when there is an electromagnetic interference source in the surroundings, the satellite signal will be masked under other signals, making it impossible to lock the satellite.

S103. If no positioning signal is obtained, save the target identification information and target signal strength information corresponding to the current target service area of the terminal device to a preset signal identification library.

In some feasible implementations, if the terminal device determines that the positioning signal has not been obtained, it can save the target identification information and target signal strength information corresponding to the current target service area of the terminal equipment to a preset signal identification library.

Among them, the signal identification library can be used to store identification information and signal strength information of the corresponding service area when the terminal device cannot search for the positioning signal. It should be noted that the signal identification library can store multiple sets of identification information and signal strength information of service areas. Each set of identification information and signal strength information corresponds to the current service area of the terminal device when the terminal device does not obtain a positioning signal. identification information and signal strength information.

The target identification information refers to the ID of the cell where the terminal device is currently located. The target signal strength information refers to the indication information of the wireless signal quality currently received by the terminal device from the base station.

Optionally, the identification information of the service area may include PCI (Physical Cell Identifier, physical cell identifier) or Cell ID (Cell Identity, cell identification code). The signal strength information may include one of Received Signal Strength Indication (RSSI), Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (RSRQ), or Multiple items.

For example, when the identification information of the service area is Cell ID and the signal strength information is RSSI, it is assumed that three sets of Cell ID and RSSI can be stored in the satellite-free identification database. Among them, the first set of Cell ID and RSSI are 3F and -85dBm respectively. The second set of Cell ID and RSSI are 80 and -60dBm respectively. The third group of Cell ID and RSSI are 0A and -75dBm respectively.

It should be understood that if the terminal device determines that the positioning signal has not been acquired, it means that the terminal device cannot determine the current location of the terminal device through the first positioning mode.

S104. Mark the positioning state as the second positioning state, and perform positioning through the second positioning mode.

In some feasible implementations, after determining that the positioning signal has not been acquired, the terminal device may mark the positioning state of the first positioning mode of the terminal device as the second positioning state, and may perform positioning in the second positioning mode.

Optionally, the second positioning mode may be LBS (Location Based Services) positioning. The embodiment of the present application does not specifically limit the type of the second positioning mode.

It should be noted that LBS positioning can use the distance measured by the base station to the terminal device to determine the current location of the terminal device. Specifically, the terminal device can calculate the distance between it and the surrounding base stations (at least three base stations) through measurement, and then draw a circle with each base station as the center and the measured distance as the radius. The obtained intersection point is the current location of the terminal device.

Optionally, when the second positioning mode is LBS positioning, after the terminal device starts LBS positioning, the instruction information can be sent to the cloud platform LBS positioning system. After the cloud platform LBS positioning system receives the instruction information, it can use the LBS positioning to determine the current location of the terminal device, and save the terminal location of the terminal device to the cloud platform LBS positioning system so that the terminal device can use its current location information when needed. Get and use it when needed.

In an optional implementation, when the second positioning mode is LBS positioning, when the terminal device performs positioning through LBS positioning, the terminal device can also combine wireless communication technology WiFi positioning to determine the current location of the terminal device. Location.

It should be noted that each wireless router has a globally unique MAC address (Media AccessControl Address, Media Access Control Address or LAN address), and generally speaking, wireless routers will not move for a period of time. When WiFi is turned on, the terminal device can scan and collect the surrounding router signals. Regardless of whether it is encrypted, connected, or even the signal strength is not strong enough to be displayed in the wireless signal list, it can obtain the AP (Access Point, wireless access point). entry point) broadcast MAC address. The terminal device sends the data that can identify the AP to the location server. The server retrieves the geographical location of each AP and combines the strength of each signal to calculate the current geographical location of the terminal device.

In the above implementation, after the terminal device is positioned through LBS, it can be combined with WiFi positioning to determine the current location of the terminal device, which can improve the positioning accuracy of the terminal device and enhance the user experience.

In this embodiment of the present application, when the terminal device is positioning in the first positioning mode, if it determines that the positioning signal is not obtained in an area, it can switch the positioning mode and start the second positioning mode to obtain the location information of the terminal device, so that it can It improves the positioning efficiency of the terminal device, reduces the power consumption of the terminal device, increases the battery life of the terminal device, and improves the user experience.

In some feasible implementations, please refer to FIG. 2 , which is a schematic flowchart of yet another positioning mode control method provided by an embodiment of the present application. As shown in Figure 2, the method may also include the following steps:

S105. If the positioning state is not the first positioning state, determine whether the signal identification database contains identification information that matches the target identification information, and whether the difference between the signal strength information corresponding to the identification information and the target signal strength information is less than a predetermined value. Set threshold.

In some feasible implementations, if the positioning state of the terminal device is not the first positioning state, it can determine whether the signal identification library contains identification information that matches the target identification information, and the signal strength information corresponding to the identification information is consistent with the target identification information. Whether the difference in signal strength information is less than the preset threshold.

The preset threshold may be pre-configured, or may be set according to user needs and input by managers. For example, the preset threshold may be 5 (dBm).

In an optional implementation, when the identification information of the service area is Cell ID and the signal strength information is RSSI, after the terminal device determines that the positioning state of the first positioning mode is not the first positioning state, if It is determined that the Cell ID in the signal identification library is equal to the target Cell ID, and the difference between the RSSI existing in the signal identification library and the target RSSI is less than the preset threshold, then it can be determined that the signal identification library contains an identification that matches the target Cell ID. information, and the difference between the RSSI corresponding to the Cell ID and the target RSSI is less than the preset threshold. If the terminal device determines that there is no Cell ID in the signal identification library that is equal to the target Cell ID, and/or, the difference between the RSSI that does not exist in the signal identification library and the target RSSI is less than the preset threshold, it can determine that there is no cell ID stored in the signal identification library. Identification information that matches the target Cell ID, and/or the difference between the RSSI corresponding to the Cell ID and the target RSSI is not less than the preset threshold.

For example, assume that the Cell ID (hexadecimal) saved in the satellite-free identification library is 3F, 80, 0A, and the RSSI saved is -85dBm, -60dBm, -75dBm. Assume the preset threshold is 5dBm. Assume that the target Cell ID is 80 and the target RSSI is -72dBm. Since there is a Cell ID of 80 in the non-satellite signal identification library, the terminal device can determine that there is a Cell ID in the non-satellite signal identification library that matches the target Cell ID 80. Moreover, since the difference between the RSSI with the value of -75dBm and the target RSSI with the value of -72dBm in the non-satellite signal identification library is 3dBm, that is, the difference between the RSSI in the non-satellite signal identification library and the target RSSI is less than the preset value. Threshold 5dBm. Further, the terminal device may determine that the signal identification library stores identification information that matches the target Cell ID, and the difference between the RSSI corresponding to the Cell ID and the target RSSI is less than a preset threshold.

In yet another optional implementation, when the identification information of the service area is Cell ID and the signal strength information is reference signal received power RSRP, the terminal device determines that the positioning state of the first positioning mode is not the first positioning state. After that, if the terminal device determines that the Cell ID in the signal identification library is equal to the target Cell ID, and the difference between the RSRP existing in the signal identification library and the target RSRP is less than the preset threshold, it can determine that the Cell ID stored in the signal identification library is the same as the target Cell ID. Matching identification information, and the difference between the RSRP corresponding to the Cell ID and the target RSRP is less than the preset threshold. If the terminal device determines that there is no Cell ID in the signal identification library that is equal to the target Cell ID, and/or, the difference between the RSRP that does not exist in the signal identification library and the target RSRP is less than the preset threshold, it can determine that there is no cell ID stored in the signal identification library. Identification information that matches the target Cell ID, and/or the difference between the RSRP corresponding to the Cell ID and the target RSRP is not less than the preset threshold.

In yet another optional implementation, when the identification information of the service area is Cell ID and the signal strength information is reference signal reception quality RSRQ, the terminal device determines that the positioning state of the first positioning mode is not the first positioning state. After that, if the terminal device determines that the Cell ID in the signal identification library is equal to the target Cell ID, and the difference between the RSRQ existing in the signal identification library and the target RSRQ is less than the preset threshold, it can determine that the Cell ID stored in the signal identification library is the same as the target Cell ID. Matching identification information, and the difference between the RSRQ corresponding to the Cell ID and the target RSRQ is less than the preset threshold. If the terminal device determines that there is no Cell ID in the signal identification library that is equal to the target Cell ID, and/or, the difference between the RSRQ that does not exist in the signal identification library and the target RSRQ is less than the preset threshold, it can determine that there is no cell ID stored in the signal identification library. Identification information that matches the target Cell ID, and/or the difference between the RSRQ corresponding to the Cell ID and the target RSRQ is not less than the preset threshold.

S106, if it is determined to be yes, positioning is performed through the second positioning mode.

In some feasible implementations, if the terminal device determines that there is no identification information matching the target identification information stored in the satellite signal identification library, and the difference between the signal strength information corresponding to the identification information and the target signal strength information is less than the preset threshold , then positioning can be performed through the second positioning mode to obtain the current location information of the terminal device.

S107, if the determination is no, positioning is performed through the first positioning mode.

In some feasible implementations, the terminal device determines that no identification information matching the target identification information is stored in the satellite-free identification database, and/or the difference between the signal strength information corresponding to the identification information and the target signal strength information is is not less than the preset threshold, positioning can be performed through the first positioning mode to obtain the current location information of the terminal device.

In the above implementation, in an area where the positioning signal cannot be searched, after the first positioning fails through the first positioning mode, the terminal device will no longer use the first positioning mode for positioning, but directly use the second positioning mode for positioning, so that it can Effectively improve the positioning efficiency of terminal equipment, reduce the power consumption of terminal equipment, and improve the battery life of terminal equipment.

In some feasible implementations, please refer to FIG. 3 , which is a schematic flowchart of yet another positioning mode control method provided by an embodiment of the present application. As shown in Figure 3, the method may also include steps:

S108, if the positioning signal is obtained, mark the positioning state as the first positioning state, and wait for the expiration of the positioning period corresponding to the first positioning mode.

In some feasible implementations, if the terminal device obtains the positioning signal, it can mark the positioning state of the first positioning mode as the first positioning state and wait for the expiration of the positioning period corresponding to the first positioning mode.

It should be understood that if the terminal device can obtain the positioning signal, it means that the terminal device can determine its current position through the first positioning mode and mark its positioning state in the first positioning mode as the first positioning state.

In the above implementation, after it is determined that the terminal device can obtain the positioning signal, its positioning status is marked and waits for the expiration of its positioning period, which can improve the subsequent positioning efficiency of the terminal device and reduce its power consumption.

In some feasible implementations, please refer to FIG. 4 , which is a schematic flowchart of yet another positioning mode control method provided by an embodiment of the present application. It should be understood that step S109 should be performed before step S101. As shown in Figure 4, the method may also include steps:

S109: Determine whether the positioning period corresponding to the first positioning mode has expired.

In some feasible implementations, before the terminal device obtains the positioning status corresponding to its first positioning mode, the terminal device may determine whether the positioning period corresponding to its first positioning mode has expired.

S110, if it expires, obtain the target identification information and target signal strength information corresponding to the current target service area of the terminal device, and the positioning status corresponding to the first positioning mode of the terminal device.
