Description

Technical Field

[0001] This application relates to the fields of computer and communication technologies, and in particular, to a positioning processing method, apparatus, computer-readable medium, and electronic device. Background Art

[0002] The basic principle of a high-precision positioning mechanism based on GNSS (Global Navigation Satellite System)-RTK (Real-time kinematic) is that an RTK server generates RTK assistance information suitable for the approximate location of a terminal device and then sends it to the terminal for positioning. As the number of terminals in the network increases, the load on high-precision positioning network facilities also increases, which also affects the real-time performance of positioning, making it difficult for the GNSS-RTK positioning mechanism to adapt to real-time positioning scenarios, such as autonomous driving / unmanned driving.

For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to the actual situation.

[0033] Figure 1 A schematic diagram of an exemplary system architecture to which the technical solutions of the embodiments of this application can be applied is shown.

[0034] As Figure 1 shown, the system architecture may include a terminal device 101 (the terminal device 101 can be one or more of a smart phone, a tablet computer, and a portable computer, and of course can also be a desktop computer, etc.), a network 102, a positioning server 103, and an LCS (Location Service) client 104. The network 102 is used to provide a medium for a communication link between the terminal device 101 and the positioning server 103. The LCS client 104 can be deployed on the terminal device 101, or on the positioning server 103, and of course can also be independent of the terminal device 101 and the positioning server 103.

[0035] It should be understood that Figure 1The numbers of the terminal devices, positioning servers, and LCS clients therein are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, positioning servers, and LCS clients.

[0036] In an embodiment of the present application, the LCS client 104 may send a positioning request message to the positioning server 103. The positioning request message includes indication information of a variable positioning interval, and the indication information is used to indicate that positioning processing is performed in a manner of variable positioning interval. For example, it indicates that the positioning server 103 reports positioning results in a manner of variable positioning interval. After receiving the positioning request message, the positioning server 103 may determine a target positioning interval for positioning processing based on the indication information of the variable positioning interval included in the positioning request message. For example, it may select a positioning interval from the multiple positioning intervals indicated in the indication information as the target positioning interval, and then report the positioning result based on the determined target positioning interval.

[0037] In an embodiment of the present application, the LCS client 104 may also send a positioning request message to the terminal device 101. Similarly, the positioning request message includes indication information of a variable positioning interval, and the indication information is used to indicate that positioning processing is performed in a manner of variable positioning interval. For example, it indicates that the terminal device 101 reports measurement results of positioning signals in a manner of variable positioning interval. After receiving the positioning request message, the terminal device 101 may determine a target positioning interval for positioning processing based on the indication information of the variable positioning interval included in the positioning request message. For example, it may select a positioning interval from the multiple positioning intervals indicated in the indication information as the target positioning interval, and then report the measurement results of the positioning signals to the positioning server 103 based on the determined target positioning interval. After receiving the measurement results, the positioning server 103 performs positioning calculation processing on the measurement results to obtain the positioning location of the terminal device 101, and then feeds it back to the LCS client 104.

[0038] In an embodiment of the present application, the positioning server 103 or the terminal device 101 may also dynamically adjust the positioning interval according to information such as the positioning tracking accuracy of the terminal, the accuracy of redundant positioning devices in the terminal, the network latency between the terminal and the network side, the network load between the terminal and the network side, the geographical location of the terminal, and the environment where the terminal is located, so as to dynamically adjust the positioning interval to reduce network overhead on the premise of ensuring the positioning accuracy requirements, which is beneficial to improving the real-time performance of positioning, and further ensuring that high-precision positioning better adapts to the service requirements of the terminal.

[0039] The implementation details of the technical solutions of the embodiments of the present application are elaborated in detail below:

[0040] Figure 2The flowchart of a positioning processing method according to an embodiment of the present application is shown. This positioning processing method can be executed by a terminal device or by a positioning server. Referring to Figure 2 As shown, this positioning processing method at least includes steps S210 to S240, which are introduced in detail as follows:

[0041] In step S210, a positioning request message is received. The positioning request message contains indication information of a variable positioning interval, and the indication information is used to indicate that positioning processing is performed in a manner of variable positioning interval.

[0042] In an embodiment of the present application, this positioning request message may be sent by an LCS client. Optionally, the indication information may contain a time range of the positioning interval, and the time range is used to represent the value range interval of the positioning interval. For example, the indication information may indicate a time range of 100 ms - 200 ms, and then a certain / some value(s) can be selected from this time range as the positioning interval.

[0043] In an embodiment of the present application, the indication information may further contain multiple optional values of the positioning interval. For example, it may contain 100 ms, 120 ms, 140 ms, 160 ms, 180 ms, 200 ms, etc., and then the positioning interval can be selected from these multiple optional values.

[0044] In an embodiment of the present application, in order to save the data volume during information transmission, the variable positioning interval indicated in the indication information can be transmitted in the way of bitmap or only transmitting the index. In this case, if the indication information contains bitmap information corresponding to the positioning interval value, the variable positioning interval indicated by the indication information can be determined according to the corresponding relationship between the bitmap information and the pre-stored positioning interval values; if the indication information contains index information corresponding to the positioning interval value, the variable positioning interval indicated by the indication information can be determined according to the corresponding relationship between the index information and the pre-stored positioning interval values.

[0045] In step S220, based on the indication information of the variable positioning interval, the target positioning interval for performing positioning processing is determined.

[0046] In an embodiment of the present application, when determining the target positioning interval for performing positioning processing, positioning parameters associated with the positioning processing can be obtained. The positioning parameters include at least one of the following: the positioning tracking accuracy of the terminal device, the accuracy of redundant positioning devices in the terminal device, the network latency between the terminal device and the network side, the network load between the terminal device and the network side, the geographical location of the terminal device, and the environment where the terminal device is located; then the target positioning interval is determined according to this / these positioning parameters.

[0047] In an embodiment of the present application, when determining a target positioning interval according to positioning parameters, the target positioning interval may be selected from the variable positioning intervals indicated by the indication information according to the positioning parameters; alternatively, the target positioning interval may also be directly determined according to the correspondence between the positioning parameters and the positioning interval.

[0048] In an embodiment of the present application, if the positioning parameter includes positioning tracking accuracy, the size of the determined target positioning interval is positively correlated with the positioning tracking accuracy, that is, the higher the positioning tracking accuracy of the terminal device, the larger the determined target positioning interval can be. In this way, under the premise of ensuring positioning accuracy, the network overhead caused by transmitting positioning data (such as reducing the network from sending high-precision positioning results to the terminal device) can be reduced.

[0049] In an embodiment of the present application, if the positioning parameter includes the accuracy of redundant positioning devices, the size of the determined target positioning interval is positively correlated with the accuracy of the redundant positioning devices, that is, the higher the accuracy of the redundant positioning devices in the terminal device, the larger the determined target positioning interval can be. In this way, under the premise of ensuring positioning accuracy, the network overhead caused by transmitting positioning data (such as reducing the network from sending high-precision positioning results to the terminal device) can be reduced.

[0050] In an embodiment of the present application, if the positioning parameter includes network delay information, the size of the determined target positioning interval is positively correlated with the network delay, that is, the larger the network delay, the larger the determined target positioning interval can be. This is because when the network delay is large, continuing to use the positioning data fed back by the network side will affect the positioning real-time performance and also the accuracy of the positioning result. Therefore, the positioning interval can be increased to increase the interval at which the network feeds back positioning data to the terminal device, and at the same time, other positioning methods that do not rely on the network can be used to ensure the accuracy of the terminal device's positioning result.

[0051] In an embodiment of the present application, if the positioning parameter includes network load information, the size of the determined target positioning interval is positively correlated with the network load, that is, the larger the network load, the larger the determined target positioning interval can be. This is because when the network load is large, continuing to use the positioning data fed back by the network side will increase the burden on the network, which may further lead to transmission delay and affect the accuracy of the positioning result. Therefore, the positioning interval can be increased to reduce the network burden by increasing the interval at which the network feeds back positioning data to the terminal device, and other positioning methods that do not rely on the network can also be used to ensure the accuracy of the terminal device's positioning result.

[0052] In an embodiment of the present application, if the positioning parameter includes the geographical location of the terminal device, then when it is determined that the network latency is large based on the geographical location of the terminal device (for example, it is determined that the terminal device is located in a location with high network load or in a location with poor network such as a tunnel, etc.), a larger target positioning interval can be selected. Similarly, if the positioning parameter includes the environment where the terminal device is located, then when it is determined that the network latency is large based on the environment where the terminal device is located (for example, the network quality of the environment where the terminal is located is poor, etc.), a larger target positioning interval can be selected.

[0053] In an embodiment of the present application, when determining the target positioning interval for positioning processing based on the indication information of the variable positioning interval, a target positioning interval can be selected from the variable positioning intervals indicated by the indication information based on a received positioning request message, and then a positioning process can be performed once based on the selected target positioning interval. That is, in this embodiment, a positioning request message triggers a positioning reporting process once.

[0054] In an embodiment of the present application, when determining the target positioning interval for positioning processing based on the indication information of the variable positioning interval, if at least two positioning processes need to be performed based on a received positioning request message, then when performing each positioning process, a target positioning interval is selected from the variable positioning intervals indicated by the indication information. That is, in this embodiment, a positioning request message can trigger at least two positioning reporting processes, and a positioning interval can be flexibly selected each time a positioning report is made.

[0055] In an embodiment of the present application, when determining the target positioning interval for positioning processing based on the indication information of the variable positioning interval, if at least two positioning processes need to be performed based on a received positioning request message, then a target positioning interval is selected from the variable positioning intervals indicated by the indication information and at least two positioning processes are performed. That is, in this embodiment, a positioning request message triggers at least two positioning reporting processes, and the same selected positioning interval is used for these at least two positioning reports.

[0056] In step S230, positioning processing is performed according to the determined target positioning interval.

[0057] In an embodiment of the present application, if the positioning processing method is executed by a positioning server, the process of performing positioning processing according to the determined target positioning interval can be to send the target positioning interval and differential assistance information to the terminal device, so that the terminal device can perform positioning measurement processing based on the differential assistance information and report the positioning measurement results based on the target positioning interval.

[0058] In an embodiment of the present application, after the positioning server sends the target positioning interval and differential assistance information to the terminal device, it can also receive the positioning measurement results reported by the terminal device, and then determine the positioning location of the terminal device based on the positioning measurement results. Furthermore, it can feedback the positioning location to the sender of the positioning request message (such as the LCS client) according to the target positioning interval. Of course, in an embodiment of the present application, after the positioning server sends the target positioning interval and differential assistance information to the terminal device, in addition to performing positioning measurement, the terminal device itself can also perform positioning calculation processing, and then feedback the obtained positioning location to the sender of the positioning request message according to the target positioning interval.

[0059] In an embodiment of the present application, if the positioning processing method is executed by the terminal device, the process of performing positioning processing according to the determined target positioning interval may be to obtain the differential assistance information sent by the positioning server, perform positioning measurement processing according to the differential assistance information to obtain positioning measurement results, and send the positioning measurement values to the positioning server according to the target positioning interval, so that the positioning server determines the positioning location of the terminal device based on the positioning measurement values. After the positioning server determines the positioning location of the terminal device, it can feedback the positioning location to the sender of the positioning request message (such as the LCS client) according to the target positioning interval. Of course, in an embodiment of the present application, the terminal device itself can also perform positioning calculation processing, and then feedback the obtained positioning location to the sender of the positioning request message.

[0060] In an embodiment of the present application, during the process of performing positioning processing by the terminal device or the positioning server, it can also determine whether it is necessary to update the target positioning interval according to the positioning parameters associated with the positioning processing. If it is determined that the target positioning interval needs to be updated, the positioning processing is performed according to the updated target positioning interval. The positioning parameters associated with the positioning processing include at least one of the following: the positioning tracking accuracy of the terminal device, the accuracy of the redundant positioning devices in the terminal device, the network latency between the terminal device and the network side, the network load between the terminal device and the network side, the geographical location of the terminal device, and the environment where the terminal device is located.

[0061] Figure 2 The technical solution of the illustrated embodiment enables the positioning interval to be flexibly and dynamically adjusted during positioning processing, so as to dynamically adjust the positioning interval to reduce network overhead on the premise of ensuring the positioning accuracy requirement, which is beneficial to improving the real-time performance of positioning, and further ensures that high-precision positioning better adapts to the service requirements of the terminal.

[0062] The following combines Figure 3 and Figure 4 to detail the implementation details of the technical solution of the embodiment of the present application:

[0063] As Figure 3 shown, in the positioning processing method according to an embodiment of the present application, after the terminal device establishes a PDU (Protocol Data Unit) session with the core network, the interaction process between entities includes the following steps:

[0064] Step S301, the LCS client sends a positioning request to the positioning server, and the positioning request carries indication information of a variable positioning interval. Of course, the positioning request may also carry a UE (User Equipment) identifier, which is the identifier of the terminal device to be positioned. For a 5G system, this identifier may be a GPSI (Generic Public Subscription Identifier).

[0065] In an embodiment of the present application, the indication information of the variable positioning interval may give the range of the positioning interval, such as giving a positioning interval range of 100 ms - 200 ms; or the indication information of the variable positioning interval may give several optional intervals, such as 100 ms, 120 ms, 140 ms, 160 ms, 180 ms, 200 ms, etc.

[0066] In an embodiment of the present application, in order to save information, especially in the case where the indication information needs to be transmitted over the air interface, an enumerated type value of the variable interval may be defined, and the indication information may be transmitted by bitmap or only transmitting the index.

[0067] In an embodiment of the present application, the LCS client may be deployed on the terminal device, or may be deployed on the positioning server, and may also be independent of the terminal device and the positioning server.

[0068] In an embodiment of the present application, the positioning server and the network RTK server may be independent entities, or may be deployed in one entity. As an embodiment, the positioning server may serve as an AF (Application Function).

[0069] Step S302, the positioning server generates differential assistance information.

[0070] In an embodiment of the present application, the positioning server may obtain the rough location information of the device to be positioned. For example, the positioning server interacts with the terminal device to obtain the rough location information, or the positioning server may also obtain the rough location information of the terminal device from the core network, and then obtain accurate differential assistance information based on the rough location information.

[0071] Step S303: The positioning server sends differential assistance information to the terminal device and indicates a variable positioning interval, which is used by the terminal device for positioning measurement reports.

[0072] Step S304: The terminal device performs GNSS-RTK measurements based on the differential assistance information sent by the positioning server and conducts adaptive positioning measurement reports at variable intervals.

[0073] In an embodiment of the present application, during the driving of a vehicle or the movement of a terminal, it may enter different network coverages (such as 4G network or 5G network), and the network coverage and network load may change. Therefore, when the available network bandwidth or the provided latency between the terminal device and the positioning server is limited, the terminal device can actively trigger an increase in the positioning measurement report interval to avoid further deterioration of the network environment.

[0074] Step S305: The terminal device reports the RTK measurement value to the positioning server.

[0075] Step S306: The positioning server performs positioning calculation processing based on the RTK measurement value reported by the terminal device to obtain a positioning result, and then conducts a positioning report at a variable positioning interval, that is, sends the positioning result to the LCS client.

[0076] In an embodiment of the present application, the positioning report interval can be dynamically adjusted according to factors such as the positioning tracking accuracy of the terminal device, the geographical location / travel environment of the terminal device, redundant backup positioning devices, and the current network load and latency.

[0077] Specifically, in an embodiment of the present application, the positioning tracking accuracy is related to the geographical location of the terminal device and the network environment (such as network load, network latency, etc.). For example, a vehicle equipped with an inertial navigation system is driving at a constant speed on a straight section of the road, and the accuracy of its inertial navigation system is very high. Then, if the positioning server needs to send a positioning report to the terminal device, the reporting interval of the positioning report can be increased, that is, the frequency at which the terminal device obtains a high-precision positioning report from the positioning server can be reduced (this embodiment is described by taking the positioning server for positioning calculation as an example). In other embodiments of the present application, if the terminal device performs positioning calculation, then the terminal device can reduce the measurement and calculation frequency of high-precision positioning.

[0078] In an embodiment of the present application, the redundant backup positioning device in the terminal device can also affect the positioning report interval. Specifically, after the terminal device obtains high-precision positioning, its redundant positioning device (which can be an inertial navigation system, etc.) can perform delta tracking based on the high-precision positioning. Therefore, if the accuracy of this delta tracking is higher, the positioning server can increase the interval for reporting the positioning report to the terminal device, that is, the frequency at which the terminal device obtains the high-precision positioning report from the positioning server can be lower.

[0079] In an embodiment of the present application, during the driving of the vehicle or the movement of the terminal, it may enter different network coverages (such as 4G network or 5G network), and the network coverage and network load will change. Therefore, when the available bandwidth or the provided latency between the terminal device and the positioning server is limited, the positioning server can actively trigger an increase in the positioning report interval, and the terminal device can preferentially use other positioning methods that do not rely on the network.

[0080] In an embodiment of the present application, the terminal device can also report positioning parameters to the positioning server. These positioning parameters include, but are not limited to, other positioning mechanisms in addition to 4G / 5G cellular positioning, including inertial navigation devices, motion sensors, etc. The purpose of doing this is to hand over the decision algorithm process of the positioning interval to the positioning server for implementation. The specific process is as Figure 4 shown and includes the following steps:

[0081] Step S401, the LCS client sends a positioning request to the positioning server, and the positioning request carries the requirement for a variable positioning interval. Of course, the positioning request can also carry a UE identifier, which is the identifier of the terminal device to be positioned. For a 5G system, this identifier can be a GPSI.

[0082] In an embodiment of the present application, the LCS client can be deployed on the terminal device, can also be deployed on the positioning server, and can of course be independent of the terminal device and the positioning server.

[0083] In an embodiment of the present application, the positioning server and the network RTK server can be independent entities, or can be deployed in one entity. As an embodiment, the positioning server can be used as an AF.

[0084] Step S402, the terminal device reports parameters such as positioning tracking accuracy and redundant backup positioning ability to the positioning server.

[0085] Step S403, the positioning server determines the range of the variable positioning interval according to the information reported by the terminal device and the network service status, and generates differential assistance information.

[0086] In an embodiment of the present application, the positioning server may obtain the rough location information of the device to be located. For example, the positioning server interacts with the terminal device to obtain the rough location information, or the positioning server may also obtain the rough location information of the terminal device from the core network, and then obtain accurate differential assistance information based on the rough location information.

[0087] Step S404, the positioning server sends the differential assistance information and the variable positioning interval to the terminal device. The variable positioning interval is used when the terminal device makes a positioning measurement report.

[0088] Step S405, the terminal device performs GNSS-RTK measurement according to the differential assistance information sent by the positioning server, and makes an adaptive positioning measurement report at variable intervals.

[0089] Step S406, the terminal device reports the RTK measurement value to the positioning server.
