Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a communication method and device. BACKGROUND

[0002] Positioning is one of the indispensable needs in current life, and the requirements for the delay and accuracy of positioning are becoming more and more stringent. In many positioning applications, accurate positioning is usually achieved through the combination of multiple technologies. For example, position information in an outdoor scene can be provided based on a global navigation satellite system (GNSS), various options can be provided through a radio technology network (such as a long-term evolution network) to locate a user, a wireless network, a ground beacon system, etc., and an inertial measurement unit (IMU) or a sensor (an accelerometer, a gyroscope, a magnetometer, or an atmospheric pressure sensor, etc.) can be used to determine position information.

[0003] In the related art, the enhanced positioning capability of the 3rd Generation Partnership Project (3GPP) New Radio (NR) brings additional gains, the operation of low frequency bands (FR1) and high frequency bands (FR2) and the use of a large number of antenna arrays provide additional degrees of freedom, which greatly improve the positioning accuracy. Therefore, time measurement using a large bandwidth (low frequency bands and high frequency bands) can bring better performance for user positioning, and by combining time measurement and the spatial and angular domains of the propagation channel, a more accurate user position can be achieved using a massive MIMO.

[0004] However, there is no definition of corresponding positioning integrity related information in the current 5G NR, so that the positioning integrity of the positioning system cannot be verified, resulting in that the positioning service client cannot determine whether the positioning result is reliable based on the positioning integrity of the positioning system.

Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and all other embodiments obtained by those of ordinary skill in the art without creative effort based on the embodiments in the present application shall fall into the protection scope of the present application.

[0098] It should be understood that the terms "system" and "network" are often used interchangeably in this document.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0099] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0100] In related technologies, the enhanced positioning capabilities of the 3rd Generation Partnership Project (3GPP) New Radio (NR) bring additional gains. Operation in the low-frequency band (FR1) and high-frequency band (FR2) and the use of large antenna arrays provide additional degrees of freedom, which significantly improves positioning accuracy. Therefore, utilizing large bandwidths (low-frequency and high-frequency bands) for time measurement can bring better performance to user positioning. Furthermore, by combining time measurement with the spatial and angular domains of the propagation channel using massive MIMO systems, more accurate user location can be achieved.

[0101] However, the current 5G NR does not have the definition of corresponding location integrity information, so it is impossible to verify the location integrity of the location system, which makes it impossible for the location service client to determine whether the location result is reliable based on the location integrity of the location system.

[0102] To solve the above problems, the embodiment of the present application provides a communication method and device, information for determining whether the protection level of a positioning system is greater than the warning level of the positioning system is sent by a network device to a terminal device, so that the terminal device checks whether the positioning system meets the integrity requirement according to the information, so that it can be determined in real time whether the positioning result of the positioning system is reliable.

If the terminal device 11 determines that the positioning system does not meet the integrity requirement, the terminal device 11 can record second information indicating that the positioning system is unavailable, and send the second information to the network device 12 containing the positioning service client.

[0108] The technical solutions of the embodiments of the present application will be described in detail below with examples of terminal devices and network devices. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments.

[0109] Figure 2 A flowchart of a communication method provided by the embodiments of the present application is shown. The execution subject of the embodiments of the present application is a terminal device and a network device, and the specific process of how the terminal device determines whether the positioning system meets the integrity requirement is involved. As shown in Figure 2 The method comprises:

[0110] S201, the network device sends first information to the terminal device, and the first information is used to determine whether the protection level of the positioning system is greater than the warning level of the positioning system.

[0111] In the present application, the network device can send the first information to the terminal device to perform integrity verification of the positioning system, so that the positioning service client can determine whether to rely on the positioning result of the positioning system according to whether the positioning system meets the integrity requirement.

[0112] First, the protection level of the positioning system and the warning level of the positioning system will be described below.

[0113] In this application, the protection level (PL) of a positioning system is the statistical upper limit of the positioning error (PE) of the positioning system. The alert level (AL) of the positioning system is the maximum allowed positioning error of the positioning system. The target integrity rate (TIR) is the possibility that the PE exceeds the AL and the user is not warned within the required time to alarm (TTA).

[0114] In the positioning system, it is required that the PE per unit time is greater than the AL, and the probability that the PL is less than or equal to the AL for a duration greater than the specified duration is less than the required TIR. When the PL is less than or equal to the AL, the positioning system can be used for the intended application. If the PL exceeds the AL, it should be declared that the positioning system is not suitable for the intended application to prevent loss of positioning integrity.

[0115] It should be noted that the AL, TIR and specified duration described above are key performance indicators (KPIs) autonomously specified by the positioning system. The PL described above is calculated based on a series of feared events that the positioning system may face.

[0116] Among them, the feared event includes a feared event caused by a fault and a feared event caused by a non-fault. The feared event caused by a fault is an event inherent to the positioning system, which is usually triggered by a fault of a certain element of the positioning system (such as satellite network or ground network failure). The feared event caused by a non-fault can be caused by an input error of the positioning system. For example, in a GNSS environment, the causes of the feared event caused by a non-fault can include regular time experienced every day, poor satellite geographic distribution, strong atmospheric gradient and signal interruption. The feared event caused by a non-fault reduces the positioning performance but does not cause system failure.

[0117] The first information related to the embodiments of the present application is described below.

[0118] It should be understood that the embodiments of the present application do not limit the type of the first information, as long as the terminal device can determine whether the protection level of the positioning system is greater than the alert level of the positioning system.

[0119] In some embodiments, if the network device compares the protection level of the positioning system and the alert level of the positioning system and determines the comparison result, the first information can include first indication information, and the first indication information is used to indicate the comparison result of the protection level of the positioning system and the alert level of the positioning system.

[0120] In some embodiments, if the network device does not compare the protection level of the positioning system and the warning level of the positioning system, the first information comprises second indication information, and the second indication information is used to update the protection level of the positioning system, so that the terminal device compares the protection level of the positioning system and the warning level of the positioning system after updating the protection level of the positioning system.

[0121] It should be understood that the embodiments of the present application do not limit how the network device sends the first information to the terminal device. In some embodiments, the first information can be carried in dedicated signaling or system broadcast.

[0122] S201, the terminal device determines whether the positioning system meets the integrity requirement according to the first information.

[0123] In this step, if the terminal device receives the first information sent by the network device, the terminal device can determine whether the positioning system meets the integrity requirement according to the first information.

[0124] It should be understood that whether the positioning system meets the integrity requirement can be represented in various ways, and the embodiments of the present application do not limit this.

[0125] In some embodiments, whether the positioning system meets the integrity requirement can be determined by whether the duration that the protection level of the positioning system is greater than the warning level of the positioning system exceeds a specified duration. Accordingly, after receiving the first information, the terminal device can determine whether the duration that the protection level of the positioning system is greater than the warning level of the positioning system exceeds a specified duration according to the first information. If the duration that the protection level of the positioning system is greater than the warning level of the positioning system exceeds the specified duration, the terminal device determines that the positioning system does not meet the integrity requirement. If the duration that the protection level of the positioning system is greater than the warning level of the positioning system does not exceed the specified duration, the terminal device determines that the positioning system meets the integrity requirement.

[0126] The specified duration can be a time-to-alert (TTA), and the TTA is a KPI autonomously defined by the positioning system.

[0127] It should be noted that the embodiments of the present application do not limit how to determine the duration that the protection level of the positioning system is greater than the warning level of the positioning system. In some embodiments, a target timer can be used, and the timing duration of the target timer can be the duration that the protection level of the positioning system is greater than the warning level of the positioning system.

[0128] The following describes how to use the target timer to determine the duration that the protection level of the positioning system is greater than the warning level of the positioning system for different types of first information.

[0129] In the first case, the first information comprises first indication information, and the first indication information is used to indicate a comparison result of the protection level of the positioning system and the warning level of the positioning system. Accordingly, after receiving the first information, the terminal device can start or stop running of the target timer according to the comparison result indicated by the first indication information. Subsequently, the terminal device determines whether the duration that the protection level of the positioning system is greater than the warning level of the positioning system exceeds a specified duration according to the timing duration of the target timer.

[0130] The network device can be an external network device and / or other protocol stack.

[0131] In the second case, the first information comprises second indication information, and the second indication information is used to update the protection level of the positioning system. Accordingly, after receiving the first information, the terminal device can update the protection level of the positioning system according to the second indication information. Subsequently, the terminal determines a comparison result of the protection level of the positioning system and the warning level of the positioning system, and starts or stops running of the target timer according to the comparison result of the protection level of the positioning system and the warning level of the positioning system. Finally, the terminal device determines whether the duration that the protection level of the positioning system is greater than the warning level of the positioning system exceeds a specified duration according to the timing duration of the target timer.

[0132] The second indication information is related information of positioning integrity. The embodiments of the present application do not limit how to update the protection level of the positioning system based on the second indication information, and can be specifically set according to actual conditions.

[0133] It should be understood that the embodiments of the present application do not limit how the target timer runs. In some embodiments, the target timer can start timing from zero after being started, and determine that the positioning system does not meet the integrity requirement when the timing time exceeds the specified duration. In other embodiments, the target timer can start counting down from the specified duration after being started, and determine that the positioning system does not meet the integrity requirement when the target timer counts down to zero and the timing duration of the target timer exceeds the specified duration.

[0134] It should be noted that in the first and second cases, the target timer is started when the protection level of the positioning system is greater than the warning level of the positioning system, and is stopped when the protection level of the positioning system is less than or equal to the warning level of the positioning system.

[0135] It should be noted that after the target timer is closed, if the first information received again indicates that the protection level of the positioning system is greater than the warning level of the positioning system, the target timer will clear the last timing time and start timing from zero again when restarted, or reset the timing time of the target timer to the specified duration and start counting down from the specified duration.

[0136] Optionally, in the embodiment of the present application, if the target timer expires, the terminal device can determine that the positioning system does not meet the integrity requirement, and at least one of the following processes can be performed.

[0137] In the first mode, if the terminal device initiates the positioning request, i.e., the positioning service client is on the terminal device, the terminal device can record the second information after determining that the positioning system does not meet the integrity requirement, and the second information is used to indicate that the positioning system is unavailable.
