Background technique

Many existing mobile terminals use WIFI chips to achieve terminal positioning. At the same time, existing mobile terminals have already widely supported Long Term Evolution (LTE) or higher-order communication modes.

Detailed ways

The purpose of the embodiments of the present application is to provide a terminal positioning method, device, electronic device and storage medium, so as to enable radio frequency resources to be used more efficiently and avoid waste of radio frequency resources, while ensuring to the greatest extent that the WIFI scanning process can obtain radio frequency resources for positioning the terminal.

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it can be understood by those skilled in the art that in the present application, Many technical details are provided to help readers better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in the present application can be implemented.

An embodiment of the present application relates to a terminal positioning method.

In this embodiment, the LTE communication process and the WIFI scanning process in the terminal are performed through the same radio frequency module, and the method includes: scheduling the WIFI scanning process to be performed in the idle time slot of the radio frequency module not occupied by the LTE communication process; the WIFI scanning process is stopped when the LTE communication process needs to use the radio frequency module; wherein the idle time slot includes one of the following or any combination thereof: the measurement interval time slot in the LTE communication process in the connected state; when performing the system information scheduling step in the LTE communication process, the remaining time of completing the system information scheduling step in advance in each preset system information receiving window; if the LTE communication process is performed under the discontinuous reception DRX mechanism, the remaining time after the LTE communication process is completed in each discontinuous reception cycle; and determining the location of the terminal according to the result of the WIFI scanning process.

In this embodiment, the LTE communication process and the WIFI scanning process in the terminal are performed through the same radio frequency module. Compared with the solution of deploying radio frequency modules for the LTE communication process and the WIFI scanning process respectively, the cost and power consumption can be effectively reduced. In the idle time slot of the radio frequency module not occupied by the LTE communication process, the WIFI scanning process is scheduled to be performed, which can avoid the conflict between the LTE communication process and the WIFI scanning process. In addition, compared with the resource allocation method in which both the traditional WIFI scanning process and the LTE communication process apply for the use of radio frequency resources in advance, which may cause waste of resources or fail to meet the resource requirements of the process, the method of scheduling the LTE communication process and the WIFI scanning process to use radio frequency resources respectively provided by the present application is more efficient, which can make radio frequency resources more effectively utilized and avoid waste of radio frequency resources.

Among them, the idle time slot includes one of the following or any combination thereof: the measurement interval time slot in the LTE communication process in the connected state; when performing the system information scheduling step in the LTE communication process, the remaining time to complete the system information scheduling step in advance in each preset system information receiving window; if the LTE communication process is performed under the discontinuous reception DRX mechanism, the remaining time after the LTE communication process is completed in each discontinuous reception cycle. Using the above time as an idle time slot for the WIFI scanning process to use radio frequency resources can effectively avoid the waste of radio frequency resources. In addition, the terminal positioning method provided in this embodiment provides a plurality of idle time slots in which the WIFI scanning process can obtain radio frequency resources, which can ensure to the greatest extent that the WIFI scanning process can obtain radio frequency resources and avoid the terminal being unable to be positioned for a long time. Finally, the position of the terminal can be determined according to the result of the WIFI scanning process, and the terminal positioning is completed.

The following is a detailed description of the implementation details of the terminal positioning method in this embodiment. The following content is only for the convenience of understanding the implementation details of this solution and is not necessary for implementing this solution. The specific process is shown in Figure 1 and may include the following steps:

Step 101, in the idle time slot of the LTE communication process that does not occupy the radio frequency module, the WIFI scanning process is scheduled to be performed; the WIFI scanning process is stopped when the LTE communication process needs to use the radio frequency module; wherein the idle time slot includes one of the following or any combination thereof: the measurement interval time slot in the LTE communication process in the connected state; the system information time slot in the LTE communication process; When the system information scheduling step is completed, the remaining time of each preset system information receiving window is used to complete the system information scheduling step in advance; if the LTE communication process is performed under the discontinuous reception DRX mechanism, the remaining time after the LTE communication process is completed in each discontinuous reception cycle.

Generally speaking, when LTE is in connected mode and not running in DRX mechanism, the measurement interval time slot in LTE communication process is used for neighbor measurement. In this case, WIFI scanning cannot obtain radio frequency resources for positioning, which will prolong the positioning time or cause positioning failure.

In the example where the idle time slot is included in the measurement interval time slot in the LTE communication process in the connected state, the WIFI scanning process is scheduled to be performed when the LTE communication process does not occupy the idle time slot of the RF module, which may specifically include: when the measurement interval time slot is greater than the minimum time required for the neighboring area measurement step in the LTE communication process, the neighboring area measurement step is performed using the minimum time in the measurement interval time slot, and at the end of the neighboring area measurement step, the WIFI scanning process is scheduled to be performed during the remaining time in the measurement interval time slot.

The schematic diagram of the timeline for scheduling the WIFI scanning process in the measurement interval time slot in the LTE communication process can refer to Figure 2. It can be understood that the time slots shown in Figure 2 all belong to the LTE communication process, and the RF module performs the LTE communication process in the time slot corresponding to the "LTE communication" shown in Figure 2, and schedules the WIFI scanning process in the measurement interval time slot (see the "interval time slot GAP" shown in Figure 2). In addition, it can be understood that the time slot shown in Figure 2 is the period in which the measurement interval time slot appears (see the "measurement interval time slot occurrence period" shown in Figure 2).

In the terminal positioning method provided in this example, if the measurement interval time slot can meet the minimum requirements of neighboring area measurement, the remaining time in the measurement interval time slot will be used for WIFI scanning to avoid long-term difficulty in terminal positioning, which affects the delay and accuracy of terminal positioning.

When performing the system information scheduling step in the LTE communication process, the system information (SI) scheduling step may be completed in advance, that is, the system information may be decoded in advance without occupying the entire preset system information receiving window time.

In order to release the radio frequency resources during this period of time, the remaining time of completing the system information scheduling step in advance within the preset system information receiving window can be used as an idle time slot to schedule the WIFI scanning process. The timeline diagram of scheduling the WIFI scanning process for the remaining time of completing the system information scheduling step in advance within the preset system information receiving window can refer to Figure 3. The remaining time of completing the system information scheduling step in advance within the preset system information receiving window (refer to the SI window shown in Figure 3) can refer to the idle time slot 1 or the idle time slot 2 shown in Figure 3.

In an example where the scheduling period of a system message is 640ms, the preset system message receiving window is 160ms, and the number of retransmissions of the added system message is 16, the first millisecond from the start of the preset system message receiving window may complete the matching. In this example, the remaining 159ms in the preset system message receiving window can be used to schedule the WIFI scanning process.

In the conventional scheme, when the system information is decoded in advance, a cancellation step and a step of applying for time to use radio frequency resources for the WIFI scanning process are required. Compared with the conventional scheme, this example can save time for the above steps and avoid waste of radio frequency resources.

When the idle time slot is included in the system information scheduling step in the LTE communication process, and the remaining time of the system information scheduling step is completed in advance in each preset system information receiving window, in order to ensure that the idle time slot can meet the demand of the WIFI scanning step for using radio frequency resources, the LTE communication process does not occupy the idle time slot of the radio frequency module, and schedules the WIFI scanning process to be performed. It can specifically include: when the system information scheduling step is completed in advance, detecting the remaining time in the current preset system information receiving window; when the remaining time is greater than the minimum time required for the WIFI scanning process, scheduling the WIFI scanning process to be performed.

In addition, it is worth noting that if there is remaining time for completing the system information scheduling step in advance between the preset system information receiving cycle (refer to the SI cycle shown in Figure 3) (refer to the idle time slot 3 shown in Figure 3), this time can also be used as an idle time slot to schedule the WIFI scanning process, so that the radio frequency resources can be fully utilized.

In addition, if the LTE communication process is performed under the discontinuous reception DRX mechanism, the idle time slot is the remaining time after the LTE communication process is completed in each discontinuous reception cycle, and reference can be made to Figure 4. As shown in Figure 4, in each discontinuous reception DRX cycle, the radio frequency resources are first used for the LTE communication process to perform paging and neighbor detection, and the remaining time can be used as an idle time slot to schedule the WIFI scanning process (see "WIFI Scan 1", "WIFI Scan 2" and "WIFI Scan n" shown in Figure 4).

In one example, the above-mentioned scheduling of the WIFI scanning process to be performed when the LTE communication process does not occupy the idle time slot of the radio frequency module can also be achieved by adding both the LTE communication process and the WIFI scanning process to the scheduling table and setting priorities for the LTE communication process and the WIFI scanning process respectively. In this example, scheduling the WIFI scanning process to be performed when the LTE communication process does not occupy the idle time slot of the radio frequency module can specifically include: scheduling the WIFI scanning process to be performed when the LTE communication process does not occupy the idle time slot of the radio frequency module according to the priorities of the LTE communication process and the WIFI scanning process in the scheduling table; wherein the priority of the LTE communication process in the scheduling table is higher than that of the WIFI scanning process.

Adding both the LTE communication process and the WIFI scanning process to the scheduling table can conveniently and flexibly schedule the above processes and improve the speed of scheduling the two processes. Compared with the solution of two processes applying for the use of radio frequency resources separately, it can greatly save time and avoid conflicts between the two processes. In this example, the WIFI scanning process can be understood as an inter-system measurement of the LTE communication process. Accordingly, the scheduling of the WIFI scanning process involved in this example can be understood as an inter-frequency measurement scheduling of LTE.

In addition, since the LTE communication process is generally a more basic function for the terminal device, in this example, the priority of the LTE communication process in the scheduling table is set higher than the WIFI scanning process. And according to the priorities of the LTE communication process and the WIFI scanning process in the scheduling table, the WIFI scanning process is scheduled when the LTE communication process does not occupy the idle time slot of the RF module. The process is carried out. It can ensure that the WIFI scanning process is carried out on the basis of meeting the resources required for the LTE communication process, ensuring the normal progress of the more basic LTE communication process.

In the case where the time for suspending the LTE communication process is preset to perform the WIFI scanning process, if the service cell is detected to be lost during the LTE communication process, it is necessary to apply for another time for the network search process. Since it takes a certain amount of time to apply for the network search process, it is generally necessary to terminate the ongoing WIFI scanning process while the network search process is in progress. In addition, this method requires arranging a protection interval for the network search process, which will prolong the time for terminating the WIFI scanning process, resulting in time delay and waste of radio frequency resources.

In order to solve the above problems, in one example, the network search process can also be added to the scheduling table, and the priority of the network search process in the scheduling table can be set higher than the WIFI scanning process. In this example, the terminal positioning method can also include: in the case of detecting that the service cell is lost through the LTE communication process, scheduling the network search process to be performed when the LTE communication process stops, and scheduling the WIFI scanning process to be performed after the network search process is completed. In the terminal positioning method provided in this example, if the service cell is lost when the LTE communication process is performed, since the priority of the network search process is higher than the WIFI scanning process, the network search process can be directly scheduled, saving the waiting time of the WIFI scanning process and avoiding the waste of radio frequency resources. The timeline schematic diagram of scheduling the network search process when the LTE communication process stops and scheduling the WIFI scanning process after the network search process is completed in this example can refer to Figure 5. It can be understood that the meanings represented by the remaining identifiers in Figure 5 are the same as those in Figure 4. In order to reduce repetition, they are not repeated here.

Step 102, determining the location of the terminal according to the result of the WIFI scanning process.

In this step, the location of the terminal can be finally obtained according to the result of the WIFI scanning process.

In addition, it is worth mentioning that if there is no interval time slot and the LTE communication process is not running in the DRX mechanism, the WIFI scanning process may not be able to proceed for a long time, and the terminal cannot be positioned. In order to avoid the WIFI scanning process from failing to obtain radio frequency resources for a long time, resulting in a long terminal positioning time or positioning failure, an interval time slot can be set within a certain period to enable the WIFI scanning process to obtain radio frequency resources. In an example, the positioning method of the terminal may also include: in the case where there is no idle time slot in the LTE communication process, if the LTE communication process performs downlink transmission in frequency division duplex mode, the LTE communication process is periodically suspended and the WIFI scanning process is scheduled to be performed within a preset time length. Therefore, in the case where there is no measurement interval time slot in the LTE communication process, the LTE communication process for downlink transmission in frequency division duplex mode is periodically suspended, and the WIFI scanning process is scheduled to be performed within a preset time length. It can avoid affecting the positioning delay and accuracy due to the inability to perform the WIFI scanning process for a long time. The timeline schematic diagram involved in this example can refer to Figure 6. In this example, it can be understood that the interval time slot is manually set so that the WIFI scanning process can obtain radio frequency resources, and the manually set interval time slot is shown as the interval time slot in Figure 6. In addition, the measurement interval time slot may be set to have the interval time slot occurrence period shown in FIG. 6 as a period.

When the LTE communication process performs uplink transmission in time division duplex mode, the LTE communication process only occupies the RF resources corresponding to the uplink transmission. In order to avoid wasting the RF resources used by the WiFi scanning process for downlink transmission, in another example In the case where the LTE communication process does not occupy the idle time slot of the radio frequency module, the WIFI scanning process is scheduled to be performed, and it may also include: when the LTE communication process performs uplink transmission in time division duplex mode, the WIFI scanning process is scheduled to be performed in the time slot preset in the LTE communication process for uplink transmission (such as the LTE communication preset uplink time slot shown in Figure 7); wherein, the resources of the radio frequency module used by the WIFI scanning process are the resources used by the LTE communication process for downlink transmission. It can avoid that the radio frequency resources corresponding to the downlink transmission are wasted when the LTE communication process performs uplink transmission in time division duplex mode. In addition, since the LTE communication process only occupies the resources required for uplink transmission, scheduling the WIFI scanning process to use the resources required for downlink transmission will not affect the LTE communication process. The timeline schematic diagram involved in this example can refer to Figure 7.

In the terminal device that uses the radio frequency module for the LTE communication process and the WIFI scanning process, the LTE communication process and the WIFI scanning process need to apply in advance for a fixed radio frequency resource usage duration starting from a certain point in the future. This may result in the application of a usage duration that exceeds the actual requirement, resulting in a waste of radio frequency resources. In addition, the application of a usage duration that is insufficient may result in the termination of the process, and the next application for a usage duration may not be authorized, resulting in the failure of the LTE communication process or the WIFI scanning process.

In this embodiment, the LTE communication process and the WIFI scanning process in the terminal are performed through the same radio frequency module. Compared with the solution of deploying radio frequency modules for the LTE communication process and the WIFI scanning process respectively, the cost and power consumption can be effectively reduced. In the idle time slot of the radio frequency module not occupied by the LTE communication process, the WIFI scanning process is scheduled to be performed, which can avoid the conflict between the LTE communication process and the WIFI scanning process. In addition, compared with the resource allocation method in which both the traditional WIFI scanning process and the LTE communication process apply for the use of radio frequency resources in advance, which may cause resource waste or fail to meet the resource requirements of the process, the method of scheduling the LTE communication process and the WIFI scanning process to use radio frequency resources respectively provided by the present application is more efficient, which can make radio frequency resources more effectively utilized and avoid waste of radio frequency resources. Furthermore, the method of applying for the use of radio frequency resources in advance needs to reserve protection time slots between different processes, and the present application can save the radio frequency resources corresponding to the protection time slot.

An embodiment of the present application relates to a terminal positioning device, wherein the LTE communication process and the WIFI scanning process in the terminal to be positioned are performed by the same radio frequency module. The structural schematic diagram of the terminal positioning device is shown in FIG8, including:

The resource scheduling module 801 is used to schedule the WIFI scanning process to proceed when the LTE communication process does not occupy the idle time slot of the RF module; the WIFI scanning process stops when the LTE communication process needs to use the RF module;

The idle time slot includes one of the following or any combination thereof: a measurement interval time slot in the LTE communication process in the connected state; when performing the system information scheduling step in the LTE communication process, the remaining time in each preset system information receiving window after the system information scheduling step is completed in advance; if the LTE communication process is performed under the discontinuous reception DRX mechanism, the remaining time after the LTE communication process is completed in each discontinuous reception cycle;

The location determination module 802 is used to determine the location of the terminal according to the result of the WIFI scanning process.

In one example, the resource scheduling module 801 can also be used to schedule the WIFI scanning process to be performed when the LTE communication process does not occupy the idle time slot of the RF module according to the priorities of the LTE communication process and the WIFI scanning process in the scheduling table; wherein the priority of the LTE communication process in the scheduling table is higher than that of the WIFI scanning process.

In an example in which a network search process is also included in a scheduling table and the network search process has a higher priority than a WIFI scanning process in the scheduling table, the resource scheduling module 801 can also be used to schedule the network search process to be performed when the LTE communication process stops when a service cell loss is detected through the LTE communication process, and to schedule the WIFI scanning process to be performed after the network search process is completed.

In one example, the resource scheduling module 801 can also be used to schedule the WIFI scanning process to perform uplink transmission in the time slot preset in the LTE communication process when the LTE communication process performs uplink transmission in time division duplex mode; wherein the resources of the radio frequency module used by the WIFI scanning process are the resources used by the LTE communication process for downlink transmission.

In one example, the resource scheduling module 801 can also be used to periodically suspend the LTE communication process and schedule the WIFI scanning process to be performed within a preset time period if there is no idle time slot in the LTE communication process and the LTE communication process performs downlink transmission in frequency division duplex mode.

In an example where an idle time slot is a measurement interval time slot in an LTE communication process in a connected state, the resource scheduling module 801 can also be used to use the minimum time in the measurement interval time slot to perform the neighbor measurement step when the measurement interval time slot is greater than the minimum time required for the neighbor measurement step in the LTE communication process, and schedule the WIFI scanning process to be performed during the remaining time in the measurement interval time slot when the neighbor measurement step ends.

In an example where an idle time slot is the remaining time for completing the system information scheduling step in advance within each preset system information receiving window when the system information scheduling step is completed in advance; when the remaining time is greater than the minimum time required for the WIFI scanning process, the WIFI scanning process is scheduled to proceed.

The terminal positioning device provided in this embodiment schedules the WIFI scanning process to be performed during the idle time slot of the RF module not occupied by the LTE communication process, thereby avoiding the conflict between the LTE communication process and the WIFI scanning process. In addition, compared with the traditional resource allocation method in which both the WIFI scanning process and the LTE communication process apply for the use of RF resources in advance, it may cause resource waste or The method provided in the present application for scheduling the LTE communication process and the WIFI scanning process to use radio frequency resources respectively is more efficient, and can make more effective use of radio frequency resources and avoid waste of radio frequency resources.
