[0047] It can be understood that the above-mentioned functional devices can be network elements in hardware devices, or software functions running on special hardware, or virtualized functions instantiated on a platform (for example, a cloud platform).

[0048] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0049] The positioning method and device provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0050] Please refer to Figure 2 The flow chart of a positioning method provided by the embodiments of the present disclosure.

[0051] As Figure 2 indicated, the method is executed by a terminal device, including but not limited to the following steps:

[0052] S1: receiving preconfigured first positioning assistance information.

[0053] In the NR (New Radio) system of 5G (The 5th Generation), multiple positioning technologies are introduced to position the terminal device.

[0054] Among some positioning technologies, the terminal device receives preconfigured first positioning assistance information, and when the terminal device needs to be positioned, the terminal device no longer needs to receive the positioning assistance information, and can directly use the preconfigured first positioning assistance information.

[0055] It can be understood that the terminal device can receive the preconfigured first positioning assistance information in multiple ways, for example: receiving the first positioning assistance information sent by the LMF device through the LPP (long term evolution positioning protocol) message; or receiving the first positioning assistance information provided by the LMF device broadcasted by the network side device.

[0056] S2: determining whether the first positioning assistance information is available.

[0057] Among them, the preconfigured first positioning assistance information contains a timeliness indication, and has timeliness, for example: valid in a specific area or a specific time period.

[0058] It can be understood that the first positioning assistance information of the terminal device is pre-configured, for example, pre-configured at T1 moment, and the terminal device uses the first positioning assistance information when positioning the terminal device is performed at T2 moment. There is a time difference between T1 moment and T2 moment, which may cause the pre-configured first positioning assistance information to be invalid when the terminal device is positioned, thereby causing inaccurate positioning of the terminal device.

[0059] In the embodiments of the present disclosure, whether the first positioning assistance information is available is identified, specifically, whether the terminal device exceeds a specific area of the validity of the first positioning assistance information can be detected, or whether the time of using the first positioning assistance information exceeds a specific time period of the validity of the first positioning assistance information can be judged, or the terminal device cannot measure the PRS (position reference single, PRS) according to the first positioning assistance information, and the like.

[0060] It should be noted that the above-mentioned manner is only illustrative, and is intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. The way of determining whether the first positioning assistance information is available is not enumerated one by one here. As can be known by those skilled in the art, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0061] S3: In the case that the first positioning assistance information is available, the first positioning assistance information is used.

[0062] In the embodiments of the present disclosure, whether the first positioning assistance information is available is judged, and in the case that the first positioning assistance information is available, the first positioning assistance information is used, so that the terminal device can be accurately positioned using the pre-configured first positioning assistance information, and a more accurate terminal device position can be obtained.

[0063] Through the embodiments of the present disclosure, the terminal device receives the pre-configured first positioning assistance information, determines whether the first positioning assistance information is available, and in the case that the first positioning assistance information is available, uses the first positioning assistance information. In actual positioning, whether the first positioning assistance information is available is judged when the pre-configured first positioning assistance information is used, and in the case that the first positioning assistance information is available, the terminal device is positioned using the first positioning assistance information. In this way, the problem of inaccurate positioning of the terminal device caused by using the first positioning assistance information in the case that the pre-configured first positioning assistance information is unavailable can be avoided, and a more accurate terminal device position can be obtained.

[0064] In some embodiments, the positioning method provided in the embodiments of the present disclosure, in the case that the first positioning assistance information is unavailable, a positioning assistance information request message is sent to a location management function (LMF) device.

[0065] In the embodiments of the present disclosure, in the case that the first positioning assistance information is unavailable, a positioning assistance information request message is sent to a location management function (LMF) device, for example, by sending a long term evolution positioning protocol (LPP) request assistance data, the LMF device is requested to reconfigure the positioning assistance information for the terminal device, so that the preconfigured first positioning assistance information is no longer used when the terminal device is positioned, and the reconfigured positioning assistance information requested by the terminal device is applied, thereby avoiding the problem of inaccurate positioning of the terminal device.

[0066] In some embodiments, the LMF device reconfigures the positioning assistance information for the terminal device in the embodiments of the present disclosure, which can be achieved by reconfiguring the positioning assistance information for the terminal device through a long term evolution positioning protocol (LPP) message, or re-providing the positioning assistance information to a network side device, and reconfiguring the positioning assistance information for the terminal device through the network side device.

[0067] In some embodiments, in the case that the first positioning assistance information is unavailable, an error indication message is sent to the LMF device to indicate that the first positioning assistance information is unavailable.

[0068] In the exemplary embodiments, in the case that the first positioning assistance information is unavailable, the terminal device sends an LPP error message (LPP error) to the LMF device, and the error cause is positioning assistance information error, so that the preconfigured first positioning assistance information is not used when the terminal device is positioned, thereby avoiding the problem of inaccurate positioning of the terminal device.

[0069] In some embodiments, in the case that the first positioning assistance information is unavailable, a location providing information message is sent to the LMF device; wherein the location providing information message contains error indication information indicating that the first positioning assistance information is unavailable.

[0070] In the example embodiment, in the case that the first positioning assistance information is unavailable, the terminal device sends a location provide information message to the LMF device, and the message contains error indication information indicating that the first positioning assistance information is unavailable, so that the preconfigured first positioning assistance information is not used when the terminal device is positioned, thereby avoiding the problem of inaccurate positioning of the terminal device.

[0071] In some embodiments, in the example embodiment of the present disclosure, the first positioning assistance information is unavailable, including: in the case that a message triggering the terminal device to use the first positioning assistance information is received, the terminal device is unable to measure the positioning reference signal PRS (Positioning Reference Signal) according to the first positioning assistance information.

[0072] In the example embodiment, the terminal device receives a location information request message, and the terminal device is unable to measure the positioning reference signal PRS according to the first positioning assistance information, at this time, it is indicated that the preconfigured first positioning assistance information is unavailable.

[0073] In the example embodiment of the present disclosure, in the case that the terminal device is unable to measure the positioning reference signal PRS according to the first positioning assistance information, it is determined that the first positioning assistance information is invalid, so that it can be determined that the first positioning assistance information is unavailable. On this basis, the terminal device sends a positioning assistance information request message to the LMF device, or sends an error indication message to the LMF device indicating that the first positioning assistance information is unavailable, or sends a location provide information message to the LMF device; wherein the location provide information message contains error indication information indicating that the first positioning assistance information is unavailable.

[0074] In some embodiments, in the example embodiment of the present disclosure, the first positioning assistance information is unavailable, including: in the case that the first positioning assistance information has a time limit, it is determined that the first positioning assistance information is invalid.

[0075] Specifically, the first positioning assistance information has a time limit, which can be that the first positioning assistance information is valid within a specific area and / or a specific time period.

[0076] It can be understood that the preconfigured first positioning assistance information is valid in a specific area, the preconfigured first positioning assistance information of different cells can be different, the preconfigured first positioning assistance information is valid when the terminal device is in a cell, and the first positioning assistance information can have been invalid when the terminal device moves from one cell to another cell. The first positioning assistance information is valid in a specific time period, and the preconfigured first positioning assistance information can be preconfigured to be valid in a specific time period. After the specific time period is exceeded, the preconfigured first positioning assistance information can have been invalid.

[0077] In the positioning of the terminal device, the first positioning assistance information is used without the terminal device exceeding the specific area and / or the terminal device exceeding the specific time period, indicating that the preconfigured first positioning assistance information is valid. At this time, the terminal device can be accurately positioned.

[0078] In the case where the first positioning assistance information has a time limit, the first positioning assistance information is determined to be invalid in the embodiment of the present disclosure, so that the first positioning assistance information can be determined to be unusable. On this basis, the terminal device sends a positioning assistance information request message to the LMF device, or sends an error indication message to the LMF device indicating that the first positioning assistance message is unusable, or sends a location provision information message to the LMF device; wherein the location provision information message contains error indication information indicating that the first positioning assistance information is unusable.

[0079] Please refer to Figure 3 The flow chart of another positioning method provided by the embodiment of the present disclosure.

[0080] As Figure 3 indicated, the method is executed by the terminal device and includes but is not limited to the following steps:

[0081] S11: receiving preconfigured first positioning assistance information.

[0082] Wherein, S11 has the same or similar technical effects as S1 in the above-mentioned embodiments. For the specific implementation of the S11 method, please refer to the description of the specific implementation of S1 in the above-mentioned embodiments, which will not be repeated here.

[0083] S12: determining whether the first positioning assistance information is invalid in the case where the first positioning assistance information has a time limit.

[0084] Specifically, the first positioning assistance information has a time limit, which can be that the first positioning assistance information is valid in a specific area and / or a specific time period.

[0085] It can be understood that the preconfigured first positioning assistance information is valid in a specific area, the preconfigured first positioning assistance information of different cells can be different, the preconfigured first positioning assistance information is valid when the terminal device is in a certain cell, and the first positioning assistance information can have been invalidated when the terminal device moves from one cell to another. The first positioning assistance information is valid within a specific time period, and the preconfigured first positioning assistance information can be pre-set to be valid within a specific time period. After the specific time period is exceeded, the preconfigured first positioning assistance information can have been invalidated.

[0086] In the case that the first positioning assistance information has a time limit, that is, the first positioning assistance information is valid in a specific area and / or within a specific time period, the time when the terminal device is located and / or the time when the terminal device is positioned is detected, and it can be determined whether the first positioning assistance information is invalidated.

[0087] It should be noted that the time limit of the first positioning assistance information is not only valid in a specific area and / or within a specific time period, but also valid under other conditions. It can be set as needed, and the present disclosure does not make specific limitations.

[0088] S13: In the case that the first positioning assistance information is not invalidated, the first positioning assistance information is used.

[0089] Specifically, in the case that the first positioning assistance information is not invalidated, the first positioning assistance information used for positioning the terminal device does not exceed a specific area and / or the time difference between the time when the terminal device uses the first positioning assistance information and the time when the first positioning assistance information is preconfigured does not exceed a specific time period.

[0090] Based on this, in the case that the first positioning assistance information is not invalidated, the first positioning assistance information can be directly used when positioning the terminal device, and the terminal device can be accurately positioned. S14: In the case that the first positioning assistance information is invalidated, a positioning assistance information request message is sent to the LMF device.

[0091] Specifically, in the case that the first positioning assistance information is invalidated, the first positioning assistance information used for positioning the terminal device has exceeded a specific area and / or the time difference between the time when the terminal device uses the first positioning assistance information and the time when the first positioning assistance information is preconfigured has exceeded a specific time period.

[0092] In the case that the first positioning assistance information has a time limit in the embodiment of the present disclosure, it is determined that the first positioning assistance information is invalidated, so that it can be determined that the first positioning assistance information is not available. Based on this, the terminal device sends a positioning assistance information request message to the LMF device,

[0093] In the embodiments of the present disclosure, when the first positioning assistance information exists and is time-limited, it is determined that the first positioning assistance information is invalid, and the first positioning assistance information is unavailable, a positioning assistance information request message is sent to a location management function (LMF) device, for example, by sending a long term evolution positioning protocol (LPP) request assistance data, the LMF device is requested to reconfigure the positioning assistance information for the terminal device, so that the preconfigured first positioning assistance information is no longer used when the terminal device is positioned, and the reconfigured positioning assistance information requested by the terminal device is applied, to avoid the problem of inaccurate positioning of the terminal device.

[0094] In the embodiments of the present disclosure, the LMF device reconfigures the positioning assistance information for the terminal device, which can be achieved by reconfiguring the positioning assistance information for the terminal device through a long term evolution positioning protocol (LPP) message, or re-providing the positioning assistance information to a network side device, and reconfiguring the positioning assistance information for the terminal device through the network side device.

[0095] In the exemplary embodiments, in the embodiments of the present disclosure, when the first positioning assistance information exists and is time-limited, it is determined that the first positioning assistance information is invalid, and the first positioning assistance information is unavailable, the terminal device can wait for the network side device to send an indication to trigger the use of the preconfigured first positioning assistance information, and in the case that the network side device sends the indication to trigger the use of the preconfigured first positioning assistance information, the corresponding steps are executed again. For details, refer to the steps in some embodiments of the present disclosure described above, which will not be repeated here.

[0096] Please refer to Figure 4 The flowchart of another positioning method provided by the embodiments of the present disclosure.

[0097] As Figure 4 shown, the method is executed by a terminal device, including but not limited to the following steps:

[0100] S112: In the case that a message triggering the terminal device to use the first positioning assistance information is received, it is determined whether the network side device has sent the second positioning assistance information required by the current positioning technology.

[0101] In the example embodiment, the terminal device receives a message triggering it to use the first positioning assistance information configured by the network through the LPP message, for example, the terminal device receives a location information request message, determines whether the network side device sends the second positioning assistance information required by the current positioning technology, for example, determines whether the base station broadcasts the NR DL-TDOA / DL-AoD Assistance Data message, i.e., the posSibType6-1, posSibType6-2, or posSibType6-3 message.

[0102] S113: In the case where the network side device sends the second positioning assistance information, it is determined whether the first positioning assistance information and the second positioning assistance information are consistent.

[0103] In the case where the base station sends the second positioning assistance information required by the current positioning technology, it is determined whether the first positioning assistance information and the second positioning assistance information are consistent.

[0104] It can be understood that, in the case where the first positioning assistance information and the second positioning assistance information are consistent, it indicates that the preconfigured first positioning assistance information can be applied to the current positioning technology, and the terminal device can be accurately positioned to obtain a more accurate terminal device position; however, if the first positioning assistance information and the second positioning assistance information are inconsistent, it indicates that the preconfigured first positioning assistance information is not suitable for the current positioning technology, and the first positioning assistance information may not be able to obtain a more accurate terminal device position.

[0105] S114: In the case where the first positioning assistance information and the second positioning assistance information are consistent, the first positioning assistance information or the second positioning assistance information is used.

[0106] In the example embodiment of the present disclosure, in the case where the first positioning assistance information and the second positioning assistance information are consistent, the first positioning assistance information or the second positioning assistance information can be directly used, which can be applied to the current positioning technology, i.e., can meet the needs of the current positioning technology, so as to accurately position the terminal device to obtain a more accurate terminal device position.

[0107] Please refer to Figure 4 In some embodiments, the positioning method provided in the example embodiment of the present disclosure further includes: S115: In the case where the first positioning assistance information and the second positioning assistance information are inconsistent, the second positioning assistance information is used.

[0108] In the embodiments of the present disclosure, in the case that the first positioning assistance information and the second positioning assistance information are inconsistent, the second positioning assistance information is used, and is applied to the current positioning technology, so that the requirements of the current positioning technology can be met, and the terminal device can be accurately positioned, and a more accurate terminal device position can be obtained.

[0109] In some embodiments, in the case that the first positioning assistance information and the second positioning assistance information are inconsistent, a positioning assistance information request message is sent to the LMF device.

[0110] In the embodiments of the present disclosure, in the case that the first positioning assistance information and the second positioning assistance information are inconsistent, it is determined that the first positioning assistance information is unavailable, a positioning assistance information request message is sent to the location management function (LMF) device, for example, a long term evolution positioning protocol (LPP) request assistance data is sent, so that the LMF device reconfigures the positioning assistance information for the terminal device, so that the preconfigured first positioning assistance information is no longer used when the terminal device is positioned, and the reconfigured positioning assistance information is applied, so that the problem of inaccurate positioning of the terminal device can be avoided.

[0111] In some embodiments, the LMF device reconfigures the positioning assistance information for the terminal device in the embodiments of the present disclosure, which can be achieved by reconfiguring the positioning assistance information for the terminal device through a long term evolution positioning protocol (LPP) message, or re-providing the positioning assistance information to a network side device, and reconfiguring the positioning assistance information for the terminal device through the network side device.

[0112] In some embodiments, the preconfigured first positioning assistance information is received, including receiving the first positioning assistance information sent by the LMF device through a long term evolution positioning protocol (LPP) message, or receiving the first positioning assistance information provided by the LMF device sent by the network side device through a positioning system message.

[0113] The first positioning assistance information sent by the LMF device through the long term evolution positioning protocol (LPP) message is exemplary, and the network side device transmits the first positioning assistance information sent by the LMF device to the terminal device, and the network side device can be a base station.

[0114] The first positioning assistance information provided by the LMF device sent by the network side device is received, for example, the LMF device provides the positioning assistance information to the network side device, the network side device sends the positioning assistance information to the terminal device through broadcasting, and the network side device can be a base station.

[0115] It should be noted that in the case where the network side device sends the second positioning assistance information required by the current positioning technology, the terminal device receives the preconfigured first positioning assistance information, and the first positioning assistance information and the second positioning assistance information exist at the same time. In this case, the sending mode of the first positioning assistance information and the second positioning assistance information cannot be consistent. It can be understood that in the case where the first positioning assistance information is sent by the LMF device through the long term evolution positioning protocol LPP message, the second positioning assistance information is the second positioning assistance information provided by the LMF device and sent by the network side device. In the case where the first positioning assistance information is the first positioning assistance information provided by the LMF device and sent by the network side device, the second positioning assistance information is sent by the LMF device through the long term evolution positioning protocol LPP message.

[0116] By implementing the embodiments of the present disclosure, whether the preconfigured first positioning assistance information is available can be determined in advance when the terminal device is positioned, so that the terminal device is positioned using the first positioning assistance information in the case where the first positioning assistance information is available. In this way, it can be avoided that the terminal device is not accurately positioned due to the invalidation of the first positioning assistance information, so that a more accurate terminal device position is obtained.

[0117] In some embodiments, the terminal device receives the preconfigured first positioning assistance information, and can also receive the second positioning assistance information required by the current positioning technology and sent by the network side device.

[0118] Among them, the first positioning assistance information can be the information sent by the LMF device to the terminal device through the long term evolution positioning protocol LPP message, and the second positioning assistance information is the information provided by the LMF device to the network side device and sent to the terminal device by the network side device through the positioning system message broadcast. Alternatively, the first positioning assistance information can be the information provided by the LMF device to the network side device and sent to the terminal device by the network side device through the broadcast, and the second positioning assistance information is the information sent by the LMF device to the terminal device through the long term evolution positioning protocol LPP message.

[0119] In the example embodiment, the terminal device receives the pre-configured first positioning assistance information from the LMF device through a long term evolution positioning protocol (LPP) message, and receives the second positioning assistance information required for the current positioning technology from the network side device when positioning the terminal device. The LMF device provides the second positioning assistance information to the network side device, and the network side device broadcasts the second positioning assistance information to the terminal device through a system message. In this case, the terminal device receives the LPP message and the system message, and needs to determine whether to use the LPP message or the system message.

[0120] The LPP message and the system message are determined to be consistent, and it is determined whether the LPP message is available. It is determined whether the terminal device uses the LPP message or the system message. In the case where the LPP message and the system message are consistent, the terminal device uses the LPP message or the system message. In the case where the LPP message and the system message are inconsistent, the terminal device uses the system message. In the case where the LPP message and the system message are inconsistent, a positioning assistance information request message is sent to the LMF device.

[0121] In the example embodiment, the terminal device receives the pre-configured first positioning assistance information from the LMF device through a long term evolution positioning protocol (LPP) message, and receives the second positioning assistance information required for the current positioning technology from the network side device when positioning the terminal device. The LMF device provides the second positioning assistance information to the network side device, and the network side device broadcasts the second positioning assistance information to the terminal device through a system message. In this case, the terminal device receives the LPP message and the system message, and needs to determine whether to use the LPP message or the system message.

[0122] The LPP message and the system message are determined to be consistent, and it is determined whether the LPP message is available. It is determined whether the terminal device uses the LPP message or the system message. In the case where the LPP message and the system message are consistent, the terminal device uses the LPP message or the system message. In the case where the LPP message and the system message are inconsistent, the terminal device uses the system message. In the case where the LPP message and the system message are inconsistent, a positioning assistance information request message is sent to the LMF device.
