As shown in FIG. 1, the terminal 103 can be sensed or identified by the short-range communication module according to the corresponding communication protocol in the terminal 102 close enough to the short-distance communication module provided therein, when the terminal 102 senses that the terminal 103 is When authenticating a terminal that can communicate with the terminal 102, the terminal 102 can transmit the data processed in the terminal 102 to the terminal 103 via the short-range communication module, so that the user of the terminal 103 can use the data processed in the terminal 102 on the terminal 103.

Based on the terminal 200 as shown in FIG. 2, it can be seen that the terminal can receive satellite signals by configuring the GPS unit therein. In the traditional satellite positioning scheme, the GPS unit of the terminal often polls and collects the satellite signal, so it may need to cover all the satellite parameters, resulting in a long time required to accurately collect the satellite signal of the desired satellite, and the GPS unit of the terminal and The performance requirements of hardware devices such as processing units are also relatively high. In order to overcome the above-mentioned drawbacks in the traditional satellite positioning scheme, the terminal can quickly acquire the satellite data corresponding to the target area in the target time period and improve the user experience. The present application provides a positioning solution.

Specifically, the positioning solution provided by the embodiment of the present application can be applied to a communication system including a terminal and a server, such as the communication system 100 shown in FIG. 1 , and specifically configured on the terminal and the server to implement the present application. The function modules of the positioning scheme provided by the embodiment, the function modules for executing the process may be implemented by hardware, software programming or a combination of software and hardware, for example, the server 101 and the terminal 102 and the terminal 104 in the communication system 100 respectively. The server-side software and the client software configured to implement the positioning solution provided by the embodiment of the present application are configured.

The flow of the positioning method provided by the embodiment of the present application is described below with reference to FIG. 3 based on the communication system architecture shown in FIG.

FIG. 3 is a schematic flowchart diagram of a positioning method provided by an embodiment of the present application. Specifically, the process may be performed by the first terminal, for example, the terminal 102 and the terminal 104 in FIG. 1 may be configured to implement the function module shown in FIG.

As shown in FIG. 3, the process includes the following steps:

Step 301: Divide the map into M partitions according to the setting rule, and the first terminal determines that it is necessary to acquire satellite data corresponding to N partitions in the map in a set time range in the future, where M and N are positive integers, and M is greater than or equal to N.

Specifically, in some actual scenarios, the above-mentioned setting rule for dividing the map into M partitions may be to divide the map according to longitude and/or latitude. For example, the setting rule may be that the latitude and longitude lines for dividing the map are first determined according to the set longitude interval and the latitude interval, and each geographical area separated by the latitude and longitude lines on the map is used as each partition. It can be seen that the partition obtained by the setting rule can conveniently correspond to the orbit data of the satellite, thereby facilitating calculation of satellite data corresponding to each partition for each partition.

In some actual scenarios, the above setting rule may also be to divide the map according to the administrative area. For example, the partition may be each country on the map, or more finely, an administrative area (such as a province, a district, a county, etc.) obtained by administrative division of the jurisdiction of each country. It can be seen that the partition obtained by the setting rule has the advantage that it is more in line with the user's habits and is beneficial to improving the user experience.

It should be understood that there may be other ways to set the rules for dividing the map into a plurality of partitions, and the present application will not be enumerated here.

Specifically, the M partitions that are obtained by dividing the map according to the setting rules may be identified by a number, a label, or a coordinate, etc., which is not limited in this application.

Specifically, the first terminal may determine N partitions from the M partitions obtained by dividing the map, and further determine that it is necessary to acquire satellite data corresponding to the N partitions in a future set time range.

For example, the first terminal may determine one partition from the M partitions in the map, and then N is equal to 1, thereby determining that it is necessary to acquire satellite data corresponding to the partition within a set time range in the future; for example, A terminal may also determine two or more partitions from the M partitions in the map, thereby determining that it is necessary to acquire satellite data corresponding to the plurality of partitions in a future set time range.

As an example, FIG. 4 is a schematic diagram of N partitions in a map in a positioning method provided by some embodiments of the present application. As shown in Figure 4, the map is divided into 5 × 5 total 25 partitions according to the set rules, which is equivalent to the above M = 25, assuming that the 25 partitions are identified by the number 1-25, the first terminal from the 25 partitions In the process, it is determined that it is necessary to acquire satellite data corresponding to the four partitions numbered 7, 8, 17, 25 in a set time range in the future, as shown in FIG. 4, the area filled with the oblique line, that is, Above N=4.

Specifically, in a possible implementation scenario, the first terminal may be configured to receive an instruction for acquiring satellite data, so as to determine, according to the received instruction, that the satellite data corresponding to the N partitions in the map in the set time range needs to be acquired. Wherein, the above instruction for acquiring satellite data may carry information of a set time range and N partitions.

For example, based on the communication system example shown in FIG. 1, a function module configured to perform the process shown in FIG. 3 may be configured on the terminal 102, and provided to the user of the terminal 102 through a user interface (UI) for acquiring a future satellite. The menu of data.

Specifically, the above menu may include a UI control for directly confirming that the user needs to acquire future satellite data, which is equivalent to confirming acquisition of satellite data corresponding to the default partition in the default time range, wherein the default time may be pre-configured, For the purpose of improving the user experience, the default time may be a day or a longer time starting from the current time. The default partition may also be a pre-configured N partitions, such as a user's own preset geographical area. The corresponding partition on the map, or the default partition can also be provided to the user for modification settings, etc.;

Alternatively, the menu may specifically include a UI control for providing a user to select or input (including voice or keying manner, etc.) for a future time range, which is equivalent to confirming the satellite data corresponding to the default partition within the time range required by the user. Or, the menu may also include a UI control for providing a user to select a partition or input the required partition information, which is equivalent to confirming the satellite data corresponding to the N partitions required by the user in the default time range; or, the menu is also The UI control may be specifically included to provide a user to select or input a future time range, and a UI control for providing a user to select a partition or input required partition information, which is equivalent to confirming that the time required by the user is N. Satellite data corresponding to each partition.

Further, the user of the terminal 102 can operate on the above menu according to requirements. For example, the user of the terminal 102 can select the time corresponding to the satellite data that needs to be acquired according to the geographical range that may be located in a future setting range. Range and N partitions, the above user operations are converted into instructions into the processor of the terminal 102, and the processor of the terminal 102 can further determine, according to the instruction, that the N partitions in the set time range need to be acquired. Satellite data.

After the first terminal determines, by step 301, that the satellite data corresponding to the N partitions in the map in the set time range needs to be acquired, the request message for acquiring the satellite data may be generated, and then step 302 in the process shown in FIG. 3 may be performed. .

Step 302: The first terminal sends a request message to the server, where the request message carries the set time range and the indication information of the N partitions.

In particular, the server may be configured to receive and process request messages for acquiring satellite data from any terminal or authenticated terminal, and may be configured to return its requested satellite data to the corresponding terminal.

For example, still based on the communication system example shown in FIG. 1, a functional module for receiving and processing request messages for acquiring satellite data from any terminal or authenticated terminal can be configured on the server 101, and is configurable useful. A functional module that returns its requested satellite data to the corresponding terminal. For example, server 101 can receive a request message sent by terminal 102 with which it has established a communication connection, and can return its requested satellite data to terminal 102.

Specifically, after receiving the request message sent by the first terminal through step 301, the server may parse the request message, and determine a set time range corresponding to the satellite data required by the terminal and N partitions in the map.

In a possible implementation scenario, after determining the set time range and N partitions corresponding to the satellite data required by the terminal, the server may calculate, according to the historical satellite data, the N partitions corresponding to the set time range. The satellite data returns a response message carrying the satellite data corresponding to the N partitions within the set time range to the first terminal.

Specifically, the historical satellite data may be satellite data issued by each satellite in the GPS acquired by the server and stored on the server.

Since each satellite in the GPS usually broadcasts its real-time satellite data according to a fixed period, in some practical scenarios, a GPS unit configured to receive satellite signals can be configured on the server to receive satellite data of the satellite broadcast in real time, and can be received after receiving. Stored in the storage unit of the server, the processing unit of the server performs the above calculation process by reading the historical satellite data stored in the storage unit. The server may also set an expiration date for the satellite data at each moment of the stored history, thereby ensuring the accuracy of the calculation result, for example, the expiration date may be set to one day;

Alternatively, in some practical scenarios, the server may be configured with a communication interface for communicating with a network device for storing satellite data, and the server may directly acquire historical satellite data from the network device through the communication interface. Specifically, the server may acquire historical satellite data within a preset duration from the current time to the endpoint, and the preset duration may be a period of one day or longer; and the like.

Further, after the server acquires the historical satellite data, the satellite data corresponding to the N partitions in the set time range may be calculated according to a preset algorithm. For example, the server may determine the distribution of each satellite from the historical satellite data, and then calculate the satellite data of each satellite passing through the partition in the future set time range for each of the N partitions.

Specifically, the satellite data of each satellite passing through the partition within the set time range may include an identity (Identity, ID), orbit data, and each satellite passing through the partition within the set time range. Star clock data, etc.; it can be seen that these satellite data can be used to indicate that the terminal is searching for satellite signals more efficiently.

In some practical scenarios, in order to improve the user experience, the server may also acquire historical satellite data according to a set period, calculate satellite data corresponding to each partition on the map in the default time range, and store the calculation result in the storage unit of the server. For example, the satellite data corresponding to each partition may be bound and stored in each partition. Further, after receiving the request message sent by the first terminal, if the server determines that the set time range is within the default time range, the server may directly read The stored calculation result is returned to the first terminal to speed up the response.

Specifically, the server may also store map data, and further, return the map data of the partition bound to the satellite data while returning the satellite data required by the first terminal.

Through the above process, the server will be able to return a response message carrying the satellite data corresponding to the N partitions within the set time range to the first terminal. Further, the first terminal may perform step 303 in the flow shown in FIG. 3.

Step 303: The first terminal receives a response message returned by the server.

Specifically, after receiving the response message returned by the server, the first terminal may obtain the satellite data corresponding to the N partitions within the set time range required by the response message.

After the first terminal acquires the satellite data corresponding to the N partitions in the set time range, the acquired satellite data may be stored in the storage unit of the first terminal, and then in the set time range, the first The terminal can read the satellite data corresponding to the N partitions in the set time range stored in the storage unit, and use the satellite data. Searching for satellite signals; it can be seen that, in the above manner, the first terminal can perform satellite search based on the acquired future satellite data pre-inferred by the server, which is more targeted than the current method of polling the search stars, thereby enabling Avoid the defects that the current polling of the search star leads to the search for accurate satellite signals and the long time required to achieve positioning;

In particular, in the case where the first terminal does not have the ability to communicate with the base station or the first terminal is offline, etc., so that the GPS unit of the first terminal cannot obtain the auxiliary positioning information, the traditional polling star search scheme will make the first terminal need to search. Approximately 32 pseudo random noise codes (PRNs) (corresponding to the above-mentioned satellite signals), and by the process shown in FIG. 3, the first terminal can accurately locate by searching for 4 to 5 PRNs. The time is greatly shortened.

Further, after the first terminal stores the satellite data corresponding to the N partitions in the acquired set time range to the storage unit of the first terminal, if it is detected that the second terminal establishes a communication connection with the first terminal, then A terminal may transmit satellite data corresponding to N partitions in the set time range to the second terminal, so that the second terminal can use the satellite data to search for satellite signals within the set time range.

For example, still based on the communication system example shown in FIG. 1, after the terminal 102 acquires satellite data corresponding to N partitions within a set time range by the above communication process with the server 101, since the terminal 103 is detected to have communication with it, Alternatively, the terminal 102 can transmit the satellite data acquired by the terminal 102 to the terminal 103, so that the terminal 103 can also use the satellite data to search for satellite signals within a set time range.

Specifically, after the terminal 103 is connected to the terminal 102, the terminal 102 can first confirm whether the satellite data can be transmitted to the terminal. For example, the terminal 102 can authenticate the validity of the transmission to the terminal 103, which will not be described in detail in this application.

Specifically, the second terminal may be connected to the first terminal by using a short-range wireless communication technology, and the short-range wireless communication technology may be referred to the foregoing description, and may include, for example, Bluetooth, Wi-Fi, infrared data transmission, and the like.

Further, the second terminal may specifically be a terminal having a short-range wireless communication function without a function of communicating with a base station and/or a function of communicating with a server. For example, a Bluetooth wristband with only a GPS unit and a Bluetooth watch, as a wearable device, often do not have the function of communicating with a base station due to the volume. When such a second terminal searches for satellite signals for GPS positioning, since it cannot directly obtain assistance from a base station or an Internet server, searching for satellite signals when working alone often takes a long time to complete positioning (usually more than 30 seconds), and the user experience is poor. In particular, when the second terminal of this type moves to a brand new geographical range, the time required for the GPS unit configured on the satellite unit to search for the satellite signal will be longer;

With the communication process provided by the foregoing embodiment of the present application, the second terminal of the above type can establish a communication connection with the first terminal by using the short-range wireless communication function, and then obtain the communication process between the first terminal and the server. After the satellite data corresponding to the N partitions in the set time range, the satellite data can be indirectly obtained through a communication connection established with the first terminal, so that the obtained satellite data can be used when the first device is separated from the work. The satellite data arrives with a purpose to search for satellite signals to achieve rapid positioning and enhance the user experience.

For example, based on the related descriptions in FIG. 1 and FIG. 2 above, in some actual scenarios, the first terminal may specifically be a mobile phone, a tablet computer, a notebook, etc., and the second terminal may specifically be a smart watch, a smart bracelet, or a smart device. Glasses and so on.

FIG. 5 is a schematic diagram of establishing a Bluetooth connection between a first terminal and a second terminal in a positioning method according to an embodiment of the present application.

As shown in FIG. 5, the first terminal 501 can establish a Bluetooth connection with the second terminal 502 that is also configured with the Bluetooth function module through the Bluetooth function module configured thereon, so that the first terminal 501 is obtained through the process shown in FIG. After the satellite data corresponding to the N partitions in the set time range, the satellite data may be transmitted to the second terminal 502 through the Bluetooth connection, so that the second terminal 502 searches through the GPS unit configured on the second terminal 502 within the set time range. satellite signal.

Specifically, in some scenarios in which the positioning solution provided by the foregoing embodiment of the present application is implemented by software, The function of the server side in the communication process is configured as an application (Application) service program configured on the server, and can provide a first type of application that can be configured to the first terminal of a type such as a mobile phone or a tablet (or Represented as a main App), and a second type of application (or can be represented as an Application) that can be configured to a second terminal of a type such as a Bluetooth bracelet, a Bluetooth watch, or the like;

Further, the first terminal may provide the satellite data corresponding to the N zones in the set time range by using the App service program on the main App trigger server; the second terminal may transmit the primary App to the first terminal by triggering the first terminal from the App. Obtain satellite data corresponding to N partitions within the set time range.

In view of the fact that the satellite data may have a large amount of data, when the software is implemented, the corresponding storage space may be configured for the App service program, the main App, and the App, for example, it may be a storage space of one hundred to two hundred megabytes.

For example, FIG. 6 is a schematic diagram of a communication process in a practical application of a positioning method provided by an embodiment of the present application. As shown in FIG. 6 , an App service program is configured on the server, a mobile phone (corresponding to the first terminal described above) is configured with a main App, and a watch (corresponding to the second terminal described above) is configured with a slave application, and the communication flow is as follows: :

Step 600: The map is divided into a plurality of partitions (corresponding to the above M partitions) according to a set rule in advance.

Alternatively, the map can be pre-downloaded and stored on servers, mobile phones, and watches.

Specifically, the identification information of each partition obtained by the map may be configured to an App service program on the server, a main App on the mobile phone, and a slave application on the watch.

Step 601: The user starts the main App on the mobile phone;

Specifically, after the main App is started, the UI menu may be provided to the user, thereby receiving the user input user for indicating the target time range (corresponding to the set time range mentioned above) and the target area (corresponding to the above N partitions). instruction.

Step 602: The main application on the mobile phone generates a request message for requesting satellite data corresponding to the target area in the target time range according to the user instruction, and sends the request message to the server.

Step 603: After receiving the request message, the App service program on the server parses the request message to determine a target time range and a target area corresponding to the satellite data required by the mobile phone.

Step 604: The App service program on the server initiates the calculation of the satellite data corresponding to the target area within the determined target time range; specifically, the historical satellite data may be acquired to perform the above calculation;

Step 605: After obtaining the estimated result, the App service program on the server generates a response message carrying the estimated result and feeds back to the mobile phone.

Step 606: After receiving the response message, the mobile phone parses the response message, so as to obtain satellite data corresponding to the target area in the target time range and store it; it can be seen that, by using the above steps, the mobile phone can be within the target time range. Searching for satellite signals using the acquired satellite data to complete positioning;

Step 607: the watch is sensed by the Bluetooth module in the mobile phone with the Bluetooth module provided by the watch; and the mobile phone recognizes the watch as a terminal that is authenticated to communicate with the terminal;

Step 608: The mobile phone sends the satellite data corresponding to the target area in the target time range stored by the mobile phone to the watch through a Bluetooth connection established between the watch and the watch;

Step 609: The watch stores the satellite data corresponding to the target area within the received target time range, so that the stored satellite data can be used to search for the satellite signal in the target time range to complete the positioning, thereby overcoming the current wearable terminal requirements such as watches. Polling search satellites takes time, delays in positioning, and poor user experience.

In summary, in the positioning solution provided by the foregoing embodiment of the present application, the map is divided into a plurality of partitions according to a setting rule, so that the first terminal needs to acquire one or more partitions within a set time range in the future. Corresponding Wei The star data may send a request message carrying the set time range and the indication information of the one or more partitions to the server, and receive the satellite data returned by the server and carrying the one or more partitions within the set time range. Response message, thus achieving the purpose of quickly acquiring satellite data corresponding to the target area within the target time period;

It can be seen that, due to the positioning scheme provided by the foregoing embodiment of the present application, the map is divided into several partitions (for example, divided into administrative areas), etc., because each partition has a certain latitude and longitude span, rather than a specific location (a certain latitude and longitude) ), thus reducing the computational complexity and speeding up the search time when extrapolating satellite data;

Further, in the positioning solution provided by the foregoing embodiment of the present application, the server may calculate satellite data corresponding to the target area in a future target time period (such as one day or longer) based on the historical satellite data, and the first terminal may obtain The calculated target is the satellite data corresponding to the target area in the segment. Therefore, when the target time period arrives, if the first terminal is in the target area and needs to search for satellite signals for positioning, it can be based on the pre-obtained target time range. The satellite data corresponding to the target area quickly captures the satellite signals of the satellites located above the target area, avoiding the short-time defects of capturing the satellite signals by polling the search satellites at present, improving the positioning efficiency and improving the user experience, for example, from Theoretically, by using the positioning scheme provided by the present application, as long as searching for 4 to 5 PRNs, the time required to search 32 PRNs compared to the conventional scheme is greatly shortened;

In addition, the positioning solution provided by the foregoing embodiment of the present application may be specifically implemented as an APP solution, and thus may be used by different terminals in the same partition, or may be used by terminals of different partitions at the same time, and the used terminal is not limited, and the used time is not limited. Not limited, it is convenient for the terminal to achieve fast positioning after offline.
