Technical Field

[0001] The present disclosure relates to the field of communication technologies, and more particularly, to a method for sending positioning information, a method for receiving positioning information, a device for sending positioning information, a device for receiving positioning information, a communication device, and a computer-readable storage medium. Background Art

[0002] In 5G technology, a variety of positioning technologies are introduced to enable positioning of terminals. Among them, some positioning technologies require the core network's LMF (Location Management Function) to provide positioning assistance information to the terminal. Specifically, the core network first sends the positioning assistance information to the base station, and the base station sends the positioning assistance information to the terminal through the downlink information transfer signaling DLInformationTransfer.

[0003] Accordingly, it is possible to configure positioning assistance information for connected terminals. That is, based on the current protocol, after the terminal receives the downlink information transfer signaling, the positioning assistance information obtained therefrom is used to determine the position in the connected state.

[0004] However, with the development of communication technologies, there is a positioning requirement not only for connected terminals but also for non-connected terminals. Summary of the Invention

[0005] In view of this, embodiments of the present disclosure propose a method for sending positioning information, a method for receiving positioning information, a device for sending positioning information, a device for receiving positioning information, a communication device, and a computer-readable storage medium to solve the technical problems in the related art.

[0006] According to a first aspect of an embodiment of the present disclosure, a method for sending positioning information is proposed, which is applicable to a base station. The method includes:

[0007] Receiving positioning information sent by the core network;

[0008] In response to receiving the first indication information sent by the core network, sending the positioning information to the terminal through a signaling for instructing the terminal to enter the non-connected state, where the first indication information indicates that the positioning information is for the terminal to use in the non-connected state.

[0009] According to a second aspect of an embodiment of the present disclosure, a method for sending positioning information is proposed, which is applicable to the core network. The method includes:

[0010] Sending positioning information to the base station, where the positioning information is for the terminal to perform positioning;

[0011] Sending first indication information to the base station for instructing the base station that the positioning information is for the terminal to use in the non-connected state.

[0012] According to a third aspect of the embodiments of the present disclosure, a method for receiving positioning information is provided, which is applicable to a terminal. The method includes:

[0013] Receiving a signaling for instructing the terminal to enter a disconnected state from a base station;

[0014] Obtaining positioning information from the signaling.

[0015] According to a fourth aspect of the embodiments of the present disclosure, a device for transmitting positioning information is provided, which is applicable to a base station. The device includes:

[0016] An information receiving module, configured to receive positioning information sent by a core network;

[0017] An information transmitting module, configured to, in response to receiving first indication information sent by the core network, carry the positioning information through a signaling for instructing the terminal to enter a disconnected state and send it to the terminal, where the first indication information indicates that the positioning information is for the terminal to use in the disconnected state.

[0018] According to a fifth aspect of the embodiments of the present disclosure, a device for transmitting positioning information is provided, which is applicable to a core network. The device includes:

[0019] An information transmitting module, configured to send positioning information to a base station, where the positioning information is for the terminal to perform positioning;

[0020] An indication transmitting module, configured to send first indication information to the base station, for instructing the base station that the positioning information is for the terminal to use in the disconnected state.

[0021] According to a sixth aspect of the embodiments of the present disclosure, a device for receiving positioning information is provided, which is applicable to a terminal. The device includes:

[0022] A signaling receiving module, configured to receive a signaling for instructing the terminal to enter a disconnected state from a base station;

[0023] An information obtaining module, configured to obtain positioning information from the signaling.

[0024] According to a seventh aspect of the embodiments of the present disclosure, a communication device is provided, including:

[0025] A processor;

[0026] A memory for storing executable instructions of the processor;

[0027] Wherein, the processor is configured to execute the above-mentioned positioning information transmitting method and / or positioning information receiving method.

[0028] According to an eighth aspect of the embodiments of the present disclosure, a computer-readable storage medium is provided for storing a computer program, and when the program is executed by a processor, the steps in the above-mentioned positioning information sending method and / or positioning information receiving method are implemented.

[0029] According to the embodiments of the present disclosure, the core network can not only send positioning information to the base station, but also send first indication information to the base station, so that the base station can determine the positioning information for the terminal to use in the non-connected state instead of the connected state according to the first indication information. Thus, the positioning information can be sent to the terminal by carrying it in the signaling that instructs the terminal to enter the non-connected state, rather than using the downlink information transmission signaling to carry the positioning information.

[0030] Accordingly, it enables the base station to clearly determine whether to use the signaling that instructs the terminal to enter the non-connected state to carry and send the received positioning information to the terminal, avoiding the situation where the base station cannot determine whether to send the positioning information to the terminal by carrying it in the downlink information transmission signaling or by carrying it in the signaling that instructs the terminal to enter the non-connected state, and avoiding problems in sending the positioning information.

[0060] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0061] In order to achieve the positioning of non-connected state terminals, a feasible solution is to send positioning assistance information to the terminals by carrying it in a Radio Resource Control Release (RRC release) signaling.

[0062] However, the problem is that if positioning assistance information can be sent to the terminals by carrying it in the Radio Resource Control Release signaling, then for the base station, the base station can both send positioning assistance information to the terminals by carrying it in downlink information transmission signaling and send positioning assistance information to the terminals by carrying it in the Radio Resource Control Release signaling.

[0063] In this case, after receiving the positioning assistance information sent by the core network, the base station does not know whether to carry the positioning assistance information and send it to the terminal through the downlink information transmission signaling or carry the positioning assistance information and send it to the terminal through the radio resource control release signaling, which easily leads to problems in sending the positioning assistance information.

[0064] Figure 1 FIG. 4 is a schematic flowchart of a positioning information sending method shown according to an embodiment of the present disclosure. The positioning information sending method shown in this embodiment can be applied to a base station, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station. The base station can communicate with the core network and a terminal serving as a user equipment, and the terminal includes but is not limited to communication devices such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device.

[0065] In one embodiment, the terminal can be the terminal applicable to the positioning information receiving method described in any subsequent embodiment. The core network can be the core network applicable to the positioning information sending method described in any subsequent embodiment.

[0066] As Figure 1 shown, the positioning information sending method can include the following steps:

[0067] In step S101, receive the positioning information sent by the core network;

[0068] In step S102, in response to receiving the first indication information sent by the core network, send the positioning information to the terminal through the signaling for instructing the terminal to enter the disconnected state, where the first indication information indicates that the positioning information is for the terminal to use in the disconnected state.

[0069] In one embodiment, the core network can send positioning information to the base station, where the positioning information includes but is not limited to at least one of the following:

[0070] Positioning assistance information, positioning request information.

[0071] Among them, the content carried in the positioning assistance information includes but is not limited to the configuration information of the positioning reference signal, and the terminal can receive the positioning reference signal according to the configuration information; the content carried in the positioning request information includes but is not limited to a positioning request for requesting location information, measurement results of the positioning reference signal, etc. from the terminal.

[0072] In one embodiment, the signaling includes at least one of the following:

[0073] Radio resource control release signaling, radio resource control suspend signaling.

[0074] In one embodiment, the disconnected state includes at least one of the following:

[0075] Idle state, inactive state.

[0076] Based on the differences in the signaling, the disconnected state can also be different. For example, if the signaling is a Radio Resource Control Release (RRC release) signaling, then the first indication information indicates that the positioning information is for the terminal to use in the idle state; for example, if the signaling is a Radio Resource Control Suspend (RRC suspend) signaling, then the first indication information indicates that the positioning information is for the terminal to use in the inactive state.

[0077] According to an embodiment of the present disclosure, the core network can not only send the positioning information to the base station, but also send the first indication information to the base station, so that the base station can determine, according to the first indication information, that the positioning information is for the terminal to use in the disconnected state rather than in the connected state. Thus, the positioning information can be carried by the signaling that instructs the terminal to enter the disconnected state and sent to the terminal, instead of using the downlink information transmission signaling to carry the positioning information.

[0078] Accordingly, it enables the base station to clearly determine whether to use the signaling that instructs the terminal to enter the disconnected state to carry and send the received positioning information to the terminal, avoiding the situation where the base station cannot determine whether to send the positioning information to the terminal by using the downlink information transmission signaling or by using the signaling that instructs the terminal to enter the disconnected state to carry the positioning information, and avoiding problems in sending the positioning information.

[0079] In one embodiment, when the positioning information is for the terminal in the connected state, the core network may not send additional indication information and only send the positioning information to the terminal, and the base station can then determine that the positioning information is for the terminal in the connected state, and further carry the positioning information by using the downlink information transmission signaling and send it to the terminal; or when the positioning information is for the terminal in the connected state, the core network may also send additional indication information to indicate that the positioning information sent to the base station is for the terminal in the connected state, and then the base station can carry the positioning information by using the downlink information transmission signaling and send it to the terminal.

[0080] It should be noted that the terminal can agree with the network side or it is stipulated by the protocol that the terminal will use the positioning information carried in the signaling for the positioning process only after entering the disconnected state, and in the connected state, even if the terminal receives the signaling, it will not use the positioning information carried in the signaling for the positioning process.

[0081] For example, if the signaling is a Radio Resource Control Release signaling, then the terminal will use the positioning information for the positioning process after entering the idle state; for example, if the signaling is a Radio Resource Control Suspend signaling, then the terminal will use the positioning information for the positioning process after entering the disconnected state.

[0082] In addition, the positioning information sent by the core network to the base station can be newly defined positioning information, so as to be distinguished from the existing positioning information for connected terminals. For example, the existing positioning information for connected terminals includes LPP provide assistance data and LPP request location information. Then the newly defined positioning information can include LPP provide assistance data1 and LPP request location information1.

[0083] In one embodiment, the first indication information may be carried in an NR positioning protocol message.

[0084] During the positioning process, the core network can mainly send two types of information to the base station. One is the LPP PDU, and the other is the NR positioning protocol message. Since the LPP PDU is non-access stratum information, the base station generally cannot parse the content therein. For the NR positioning protocol message, the base station can parse the content therein. Therefore, by carrying the first indication information in the NR positioning protocol message, it can be ensured that the base station can parse the NR positioning protocol message to obtain the first indication information therein.

[0085] Figure 2 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 2 shown, in some embodiments, the receiving the positioning information sent by the core network includes:

[0086] In step S201, receive the protocol data unit LPP PDU of the LTE (Long Term Evolution) positioning protocol sent by the core network, and the positioning information is carried in the LPP PDU;

[0087] Wherein, the first indication information is used to indicate that the LPP PDU is for the terminal to use in the non-connected state.

[0088] In one embodiment, the core network can send the positioning information to the base station by carrying it in the LPP PDU. In this case, since the LPP PDU is non-access (NAS) layer information, the base station will not parse the content therein. That is, generally, the base station only knows that it has received the LPP PDU sent by the core network, but does not know that the positioning information is carried in the LPP PDU. Therefore, the core network can use the first indication information to indicate that the sent LPP PDU is for the terminal to use in the non-connected state. Then the base station can carry the LPP PDU containing the positioning information in the signaling and send it to the terminal.

[0089] Figure 3 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 3 shown, in some embodiments, sending the positioning information to the terminal by carrying it in a signaling for instructing the terminal to enter the non-connected state includes:

[0090] In step S301, an LPP PDU is sent to the terminal by carrying it in the signaling, and the positioning information is carried in the LPP PDU carried in the signaling.

[0091] In one embodiment, since the LPP PDU is non-access stratum information, after receiving the LPP PDU, the base station can transparently transmit the LPP PDU to the terminal. That is, generally, the base station does not parse the LPP PDU to obtain the positioning information therein, but directly sends the received LPP PDU carried in the signaling to the terminal.

[0092] Figure 4 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 4 shown, in some embodiments, receiving the positioning information sent by the core network includes:

[0093] In step S401, an NR (New Radio) positioning protocol message (such as an NRPPa message) sent by the core network is received;

[0094] In step S402, the positioning information is obtained from the NR positioning protocol message;

[0095] wherein, the first indication information indicates that the positioning information is for the terminal to use in the non-connected state.

[0096] In one embodiment, the core network can send the positioning information to the base station by carrying it in an NR positioning protocol message. In this case, since the base station can parse the content of the NR positioning protocol message to obtain the positioning information, the core network can use the first indication information to indicate that the positioning information is for the terminal to use in the non-connected state, and then the base station can carry the positioning information obtained from the NR positioning protocol message in the signaling and send it to the terminal.

[0097] Figure 5 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 5 shown, in some embodiments, sending the positioning information to the terminal by carrying it in a signaling for instructing the terminal to enter the non-connected state includes:

[0098] In step S501, the positioning information is sent to the terminal by carrying it in the signaling.

[0099] In one embodiment, after receiving the NR positioning protocol message, the base station may parse the NR positioning protocol message to obtain the positioning information therein, and then carry the positioning information obtained from the NR positioning protocol message in the signaling and send it to the terminal.

[0100] It should be noted that the NR positioning protocol message carrying the positioning information sent by the core network to the base station may be specific to a designated terminal. For example, the identifier of the designated terminal may be carried in the NR positioning protocol message, so that the base station can determine to send the positioning information to the designated terminal according to the identifier.

[0101] Figure 6 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 6 shown, in some embodiments, the method further includes:

[0102] In step S601, in response to the terminal not entering the non-connected state, send second indication information to the terminal, which is used to indicate that the sending of the positioning information to the terminal fails.

[0103] In one embodiment, although the base station can carry the positioning information in the signaling indicating that the terminal enters the non-connected state and send it to the terminal, the signaling is sent to the terminal when the terminal is about to enter the non-connected state. If the terminal does not enter the non-connected state, then the base station cannot send the signaling to the terminal, and thus cannot carry the positioning information in the signaling and send it to the terminal.

[0104] In this case, the base station can send second indication information to the terminal to indicate that the sending of the positioning information to the terminal fails, so that the terminal can determine that the base station originally intended to send the positioning information to the terminal, but for some reason the sending of the positioning information fails. Furthermore, when the terminal needs to obtain the positioning information, it can communicate with network-side devices such as the base station and the core network to re-obtain the positioning information.

[0105] Figure 7 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 7 shown, in some embodiments, the sending of the second indication information to the terminal includes:

[0106] In step S701, in response to the terminal switching to another cell, send second indication information to the terminal.

[0107] In one embodiment, the base station may send second indication information to the terminal when it determines that the terminal has switched to another cell. Among them, the terminal switching to another cell may mean that the terminal has initiated a process of switching to another cell, but still camps on the base station.

[0108] When it is determined that the terminal switches to another cell, it indicates that the terminal leaves the cell of the base station and camps on the cell of another base station. Then, the base station cannot send the positioning information to the terminal through the signaling. Therefore, in this case, the base station can completely determine that the positioning information sending to the terminal fails and indicates to the terminal that the positioning information sending fails through the second indication information.

[0109] In the case where the terminal does not switch to another cell, even if the terminal does not enter the non-connected state, since the terminal still camps on the cell of the base station, the base station still has the opportunity to send the signaling to the terminal subsequently. Therefore, it cannot be determined that the positioning information sending fails, and thus the second indication information is not sent to the terminal.

[0110] In one embodiment, the positioning information is carried in the LPP PDU, and the second indication information is used to indicate the failure of sending the LPP PDU to the terminal or the failure of sending the positioning information to the terminal.

[0111] When the positioning information is carried in the LPP PDU, the base station sending the positioning information to the terminal means that the base station sends the LPP PDU containing the positioning information to the terminal. Therefore, through the second indication information, it can indicate both the failure of sending the LPP PDU to the terminal and the failure of sending the positioning information to the terminal.

[0112] In one embodiment, the positioning information is carried in the NR positioning protocol message, and the second indication information is used to indicate the failure of sending the positioning information to the terminal.

[0113] When the positioning information is carried in the NR positioning protocol message, the base station sending the positioning information to the terminal means that the base station sends the positioning information obtained from the NR positioning protocol message to the terminal. Therefore, through the second indication information, it can indicate the failure of sending the positioning information to the terminal.

[0114] Figure 8 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 8 shown, in some embodiments, the method further includes:

[0115] In step S801, in response to the terminal not entering the non-connected state, a third indication information is sent to the core network, which is used to indicate the failure of sending the positioning information that needs to be sent to the terminal.

[0116] In one embodiment, although the base station can send the positioning information to the terminal through the signaling indicating that the terminal enters the disconnected state, the signaling is sent to the terminal only when the terminal is about to enter the disconnected state. If the terminal does not enter the disconnected state, the base station cannot send the signaling to the terminal, nor can it send the positioning information to the terminal through the signaling.

[0117] In this case, the base station can send third indication information to the core network to indicate that the positioning information that needs to be sent to the terminal by the core network fails, so that the core network determines that the base station originally intended to send positioning information to the terminal, but fails to send the positioning information for some reason. Furthermore, the core network can re-send the positioning information to the terminal as needed. For example, it can instruct the terminal to change the way of sending the positioning information so as to successfully send the positioning information to the terminal.

[0118] Figure 9 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 9 shown, in some embodiments, the sending of the third indication information to the core network includes:

[0119] In step S901, in response to the terminal switching to another cell, send third indication information to the core network.

[0120] In one embodiment, the base station can send third indication information to the core network when it determines that the terminal has switched to another cell. Among them, the terminal switching to another cell may mean that the terminal has initiated a process of switching to another cell, but still camps on the base station.

[0121] When it is determined that the terminal has switched to another cell, it means that the terminal has left the cell of the base station and camped on the cell of another base station. Then the base station cannot send the positioning information to the terminal through the signaling. Therefore, in this case, the base station can fully determine that the sending of the positioning information to the terminal fails and indicate to the core network through the third indication information that the positioning information that needs to be sent to the terminal fails.

[0122] In the case where the terminal does not switch to another cell, even if the terminal does not enter the disconnected state, since the terminal still camps on the cell of the base station, the base station still has an opportunity to send the signaling to the terminal later. Therefore, it cannot be determined that the sending of the positioning information fails, and thus the third indication information is not sent to the core network.

[0123] It should be noted that in all embodiments of the present disclosure, the terminal does not enter the disconnected state, which may mean that the terminal is in the serving cell corresponding to the base station and does not enter the disconnected state in this serving cell. This situation can be predicted by the base station. For example, the base station can predict whether the terminal will enter the disconnected state within a subsequent preset time period according to the situation of the service being carried out by the terminal and / or the communication history record. If it is predicted that the terminal will not enter the disconnected state, it is determined that the terminal does not enter the disconnected state; otherwise, it is determined that the terminal will enter the disconnected state.

[0124] In one embodiment, the positioning information is carried in the LPP PDU, and the third indication information is used to indicate that the LPP PDU to be sent to the terminal fails to be sent, or to indicate that the positioning information to be sent to the terminal fails to be sent.

[0125] When the positioning information is carried in the LPP PDU, the base station sending the positioning information to the terminal means that the base station sends the LPP PDU containing the positioning information to the terminal. Therefore, through the third indication information, it can be indicated that the core network fails to send the positioning information to the terminal that needs to be sent, or it can be indicated that the positioning information that the core network needs to send to the terminal fails to be sent.

[0126] In one embodiment, the positioning information is carried in the NR positioning protocol message, and the third indication information is used to indicate that the positioning information to be sent to the terminal fails to be sent.

[0127] When the positioning information is carried in the NR positioning protocol message, the base station sending the positioning information to the terminal means that the base station sends the positioning information obtained from the NR positioning protocol message to the terminal. Therefore, through the third indication information, it can be indicated that the positioning information that the core network needs to send to the terminal fails to be sent.

[0128] In one embodiment, the third indication information is further used to indicate the reason for the sending failure.

[0129] The base station can also inform the core network of the reason for the sending failure through the third indication information, so that the core network can determine why the positioning information to be sent to the terminal fails to be sent, and then can select to re-send the positioning information to the terminal as needed.

[0130] For example, if the reason is that the terminal switches to another cell, then the core network can determine the other base station corresponding to the other cell to which the terminal will switch. For example, it can be determined according to the identifier of the other base station carried in the third indication information, and then the positioning information and the first indication information are sent to the other base station, so that after the terminal accesses the other base station, it can obtain the positioning information sent by the core network from the other base station.

[0131] Figure 10It is a schematic flowchart of a method for sending positioning information shown according to an embodiment of the present disclosure. The method for sending positioning information shown in this embodiment can be applied to a core network, and the core network can communicate with a base station and a terminal serving as a user equipment. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations.

[0132] In one embodiment, the base station can be the base station applicable to the method for sending positioning information described in any of the above embodiments. The terminal can be the terminal applicable to the method for receiving positioning information described in any subsequent embodiment.

[0133] As Figure 10 shown, the method for sending positioning information may include the following steps:

[0134] In step S1001, send positioning information to the base station, where the positioning information is for the terminal to perform positioning;

[0135] In step S1002, send first indication information to the base station, which is used to indicate to the base station that the positioning information is for the terminal to use in a non-connected state.

[0136] It should be noted that the positioning information and the first indication information can be sent to the base station in the same sending step or in different sending steps, and can be specifically set according to needs.

[0137] In one embodiment, the core network can send positioning information to the base station, where the positioning information includes, but is not limited to, at least one of the following:

[0138] Positioning assistance information, positioning request information.

[0139] Among them, the content carried in the positioning assistance information includes, but is not limited to, configuration information of positioning reference signals, and the terminal can receive positioning reference signals according to this configuration information; the content carried in the positioning request information includes, but is not limited to, a positioning request, which is used to request location information, measurement results of positioning reference signals, etc. from the terminal.

[0140] In one embodiment, the signaling includes at least one of the following:

[0141] Radio resource control release signaling, radio resource control suspension signaling.

[0142] In one embodiment, the non-connected state includes at least one of the following:

[0143] Idle state, inactive state.

[0144] Based on the differences in the signaling, the non-connected state can also be different. For example, if the signaling is a Radio Resource Control Release (RRC release) signaling, then the first indication information indicates that the positioning information is for the terminal to use in the idle state; for example, if the signaling is a Radio Resource Control Suspend (RRC suspend) signaling, then the first indication information indicates that the positioning information is for the terminal to use in the inactive state.

[0145] According to an embodiment of the present disclosure, the core network can not only send the positioning information to the base station, but also send the first indication information to the base station, so that the base station can determine, based on the first indication information, that the positioning information is for the terminal to use in the non-connected state rather than in the connected state. Thus, the positioning information can be carried by the signaling indicating the terminal to enter the non-connected state and sent to the terminal, instead of using the downlink information transmission signaling to carry the positioning information.

[0146] Thereby, it enables the base station to clearly determine whether to use the signaling indicating the terminal to enter the non-connected state to carry and send the received positioning information to the terminal, avoiding the situation where the base station cannot determine whether to send the positioning information to the terminal by using the downlink information transmission signaling or by using the signaling indicating the terminal to enter the non-connected state, and avoiding problems in sending the positioning information.

[0147] In one embodiment, when the positioning information is for the terminal in the connected state, the core network may not send additional indication information and only send the positioning information to the terminal, and the base station can then determine that the positioning information is for the terminal in the connected state, and further carry the positioning information by using the downlink information transmission signaling and send it to the terminal; or when the positioning information is for the terminal in the connected state, the core network may also send additional indication information indicating that the positioning information sent to the base station is for the terminal in the connected state, and then the base station can carry the positioning information by using the downlink information transmission signaling and send it to the terminal.

[0148] It should be noted that the terminal can agree with the network side or it is stipulated by the protocol that the terminal will use the positioning information carried in the signaling for the positioning process only after entering the non-connected state, and in the connected state, even if the terminal receives the signaling, it will not use the positioning information carried in the signaling for the positioning process.

[0149] For example, if the signaling is a Radio Resource Control Release signaling, then the terminal will use the positioning information for the positioning process after entering the idle state; for example, if the signaling is a Radio Resource Control Suspend signaling, then the terminal will use the positioning information for the positioning process after entering the non-connected state.

[0150] In addition, the positioning information sent by the core network to the base station can be newly defined positioning information, so as to be distinguished from the existing positioning information for connected terminals. For example, the existing positioning information for connected terminals includes LPP provide assistance data and LPP request location information, then the newly defined positioning information can include LPP provide assistance data1 and LPP request location information1.

[0151] In one embodiment, the first indication information may be carried in the NR positioning protocol message.

[0152] During the positioning process, the core network can mainly send two types of information to the base station. One is the LPP PDU, and the other is the NR positioning protocol message. Since the LPP PDU is non-access stratum information, the base station generally cannot parse the content therein. For the NR positioning protocol message, the base station can parse the content therein. Therefore, by carrying the first indication information in the NR positioning protocol message, it can be ensured that the base station can parse the NR positioning protocol message to obtain the first indication information therein.

[0153] Figure 11 It is a schematic flowchart of another positioning information sending method shown according to an embodiment of the present disclosure. As Figure 11 shown, in some embodiments, the sending of the positioning information to the base station includes:

[0154] In step S1101, a protocol data unit LPP PDU of the LTE positioning protocol is sent to the base station, and the positioning information is carried in the LPP PDU;

[0155] Wherein, the first indication information is used to indicate that the LPP PDU is for the terminal to use in the non-connected state.

[0156] In one embodiment, the core network can send the positioning information to the base station by carrying it in the LPP PDU. In this case, since the LPP PDU is non-access (NAS) layer information, the base station will not parse the content therein. That is, generally, the base station only knows that it has received the LPP PDU sent by the core network, and does not know that the positioning information is carried in the LPP PDU. Therefore, the core network can use the first indication information to indicate that the sent LPP PDU is for the terminal to use in the non-connected state, then the base station can carry the LPP PDU containing the positioning information in the signaling and send it to the terminal.

[0157] Figure 12It is a schematic flowchart of another method for sending positioning information shown according to an embodiment of the present disclosure. As Figure 12 shown, in some embodiments, the sending of the positioning information to the base station includes:

[0158] In step S1201, an NR positioning protocol message is sent to the base station, and the positioning information is carried in the NR positioning protocol message;

[0159] wherein, the first indication information indicates that the positioning information is for the terminal to use in the non-connected state.

[0160] In one embodiment, the core network can send the positioning information to the base station by carrying it in the NR positioning protocol message. In this case, the base station can parse the content in the NR positioning protocol message to obtain the positioning information. Then, the core network can indicate by the first indication information that the positioning information is for the terminal to use in the non-connected state. Then, the base station can carry the positioning information obtained from the NR positioning protocol message in the signaling and send it to the terminal.

[0161] Figure 13 It is a schematic flowchart of another method for sending positioning information shown according to an embodiment of the present disclosure. As Figure 13 shown, in some embodiments, the method further includes:

[0162] In step S1301, a third indication information sent by the base station is received;

[0163] In step S1302, it is determined according to the third indication information that the sending of the positioning information that the base station needs to send to the terminal fails.

[0164] In one embodiment, although the base station can carry the positioning information in the signaling indicating that the terminal enters the non-connected state and send it to the terminal, the signaling is sent to the terminal when the terminal is about to enter the non-connected state. If the terminal does not enter the non-connected state, then the base station cannot send the signaling to the terminal, and thus cannot carry the positioning information in the signaling and send it to the terminal.

[0165] In this case, the base station can send the third indication information to the core network to indicate that the sending of the positioning information that the core network needs to send to the terminal fails, so that the core network determines that the base station originally intended to send the positioning information to the terminal, but for some reason the sending of the positioning information fails. Furthermore, the core network can re-send the positioning information to the terminal as needed. For example, it can indicate to the terminal to change the way of sending the positioning information so as to be able to successfully send the positioning information to the terminal.

[0166] Figure 14 It is a schematic flowchart of another method for sending positioning information shown according to an embodiment of the present disclosure. As Figure 14As shown, in some embodiments, the method further includes:

[0167] In step S1401, determine the reason for the transmission failure according to the third indication information.

[0168] The base station can also inform the core network of the reason for the transmission failure through the third indication information, so that the core network can determine why the positioning information to be sent to the terminal fails to be sent, and then can choose to re-send the positioning information to the terminal as needed.

[0169] For example, if the reason is that the terminal has switched to another cell, then the core network can determine the other base station corresponding to the other cell to which the terminal is about to switch, and then send the positioning information and the first indication information to the other base station, so that after the terminal accesses the other base station, it can obtain the positioning information sent by the core network from the other base station.

[0170] Figure 15 FIG. is a schematic flowchart of a method for receiving positioning information according to an embodiment of the present disclosure. The method for receiving positioning information shown in this embodiment can be applied to a terminal, and the terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with the core network and the base station as a user equipment, and the base station includes, but is not limited to, 4G base stations, 5G base stations, and 6G base stations.

[0171] In one embodiment, the base station can be the base station applicable to the positioning information sending method in any of the above embodiments. The core network can be the core network applicable to the positioning information sending method in any of the above embodiments.

[0172] As Figure 15 shown, the method for receiving positioning information may include the following steps:

[0173] In step S1501, receive a signaling for instructing the terminal to enter the non-connected state from the base station;

[0174] In step S1502, obtain the positioning information from the signaling.

[0175] In one embodiment, the core network can send positioning information to the base station, and the base station sends the positioning information to the terminal. Among them, the positioning information includes, but is not limited to, at least one of the following:

[0176] Positioning assistance information, positioning request information.

[0177] Among them, the content carried in the positioning assistance information includes, but is not limited to, the configuration information of the positioning reference signal, and the terminal can receive the positioning reference signal according to this configuration information; the content carried in the positioning request information includes, but is not limited to, a positioning request, which is used to request location information, measurement results of the positioning reference signal, etc. from the terminal.

[0178] In one embodiment, the signaling includes at least one of the following:

[0179] Radio Resource Control (RRC) release signaling, Radio Resource Control (RRC) suspend signaling.

[0180] In one embodiment, the non-connected state includes at least one of the following:

[0181] Idle state, inactive state.

[0182] Based on the difference in the signaling, the non-connected state may also be different. For example, if the signaling is Radio Resource Control (RRC) release signaling, then the first indication information indicates that the positioning information is for the terminal to use in the idle state; for example, if the signaling is Radio Resource Control (RRC) suspend signaling, then the first indication information indicates that the positioning information is for the terminal to use in the inactive state.

[0183] According to an embodiment of the present disclosure, the terminal can enter the non-connected state after receiving the signaling, and perform positioning according to the positioning information obtained from the signaling in the non-connected state, realizing the positioning of the terminal in the non-connected state. After the terminal completes the positioning, it can send the positioning result to the core network via the base station, and the core network can then obtain the positioning result of the terminal in the non-connected state.

[0184] In addition, the core network can not only send the positioning information to the base station, but also send the first indication information to the base station, so that the base station can determine according to the first indication information that the positioning information is for the terminal to use in the non-connected state rather than in the connected state, so that the positioning information can be carried by the signaling indicating the terminal to enter the non-connected state and sent to the terminal, instead of using the downlink information transmission signaling to carry the positioning information.

[0185] Accordingly, it enables the base station to clearly determine whether to use the signaling indicating the terminal to enter the non-connected state to carry and send the received positioning information to the terminal, avoiding the situation where the base station cannot determine whether to send the positioning information to the terminal by using the downlink information transmission signaling or by using the signaling indicating the terminal to enter the non-connected state, and avoiding problems in sending the positioning information.

[0186] In one embodiment, when the core network provides positioning information for a connected terminal, it may not send additional indication information, but only send the positioning information to the terminal. Then the base station can determine that the positioning information is for the connected terminal, and then carry the positioning information through downlink information transmission signaling and send it to the terminal; or when the core network provides positioning information for a connected terminal, it may also send additional indication information indicating that the positioning information sent to the base station is for the connected terminal. Then the base station can carry the positioning information through downlink information transmission signaling and send it to the terminal.

[0187] It should be noted that the terminal can agree with the network side or it is stipulated by the protocol that the terminal will use the positioning information carried in the signaling for the positioning process only after entering the non-connected state. In the connected state, even if the terminal receives the signaling, it will not use the positioning information carried in the signaling for the positioning process.

[0188] For example, if the signaling is a radio resource control release signaling, then the terminal will use the positioning information for the positioning process after entering the idle state; for example, if the signaling is a radio resource control suspend signaling, then the terminal will use the positioning information for the positioning process after entering the non-connected state.

[0189] In addition, the positioning information sent by the core network to the base station can be newly defined positioning information to distinguish it from the existing positioning information for connected terminals. For example, the existing positioning information for connected terminals includes LPP provide assistance data and LPP request location information, then the newly defined positioning information can include LPP provide assistance data1 and LPP request location information1.

[0190] Figure 16 It is a schematic flowchart of another positioning information receiving method shown according to an embodiment of the present disclosure. As Figure 16 shown, in some embodiments, the positioning information is carried in the LPP PDU carried by the signaling. The obtaining of the positioning information from the signaling includes:

[0191] In step S1601, obtain the positioning information from the LPP PDU.

[0192] In one embodiment, the core network may send positioning information to the base station through an LPP PDU. In this case, since the LPP PDU is non-access stratum (NAS) information, the base station does not parse the content therein. That is, generally, the base station only knows that it has received the LPP PDU sent by the core network, but does not know that the LPP PDU carries positioning information. Therefore, the core network may use first indication information to indicate that the sent LPP PDU is for the terminal to use in the non-connected state. Then, the base station may carry the LPP PDU containing the positioning information in the signaling and send it to the terminal.

[0193] In one embodiment, since the LPP PDU is non-access stratum information, after receiving the LPP PDU, the base station may transparently transmit the LPP PDU to the terminal. That is, generally, the base station does not parse the LPP PDU to obtain the positioning information therein, but directly carries the received LPP PDU in the signaling and sends it to the terminal. Then, the terminal may obtain the positioning information from the received LPP PDU.

[0194] In some embodiments, the signaling carries the positioning information.

[0195] In one embodiment, the core network may send positioning information to the base station through an NR positioning protocol message. In this case, the base station may parse the content in the NR positioning protocol message to obtain the positioning information. Then, the core network may use first indication information to indicate that the positioning information is for the terminal to use in the non-connected state. Then, the base station may carry the positioning information obtained from the NR positioning protocol message in the signaling and send it to the terminal.

[0196] In one embodiment, after receiving the NR positioning protocol message, the base station may parse the NR positioning protocol message to obtain the positioning information therein, and then carry the positioning information obtained from the NR positioning protocol message in the signaling and send it to the terminal. Then, the terminal may directly obtain the positioning information from the signaling.

[0197] It should be noted that the NR positioning protocol message carrying positioning information sent by the core network to the base station may be specific to a designated terminal. For example, the identifier of the designated terminal may be carried in the NR positioning protocol message, so that the base station can determine to send the positioning information to the designated terminal according to the identifier.

[0198] Figure 17 is a schematic flowchart of another positioning information receiving method shown according to an embodiment of the present disclosure. As Figure 17 shown, in some embodiments, the method further includes:

[0199] In step S1701, in response to not entering the non-connected state, receive second indication information sent by the base station;

[0200] In step S1702, it is determined that the base station fails to send positioning information to the terminal according to the second indication information.

[0201] In one embodiment, although the base station can send the positioning information to the terminal through the signaling that instructs the terminal to enter the disconnected state, the signaling is sent to the terminal when the terminal is about to enter the disconnected state. If the terminal does not enter the disconnected state, the base station cannot send the signaling to the terminal, nor can it send the positioning information to the terminal through the signaling.

[0202] In this case, the base station can send second indication information to the terminal to indicate that the base station fails to send positioning information to the terminal, so that the terminal can determine that the base station originally intended to send positioning information to the terminal, but failed to send the positioning information for some reason. Furthermore, when the terminal needs to obtain positioning information, it can communicate with network-side devices such as the base station and the core network to re-obtain the positioning information.

[0203] Figure 18 It is a schematic flowchart of another positioning information receiving method shown according to an embodiment of the present disclosure. As Figure 18 shown, in some embodiments, the receiving the second indication information sent by the base station includes:

[0204] In step S1801, in response to switching to another cell, receive the second indication information sent by the base station.

[0205] In one embodiment, the base station can send second indication information to the terminal when it determines that the terminal switches to another cell. Correspondingly, the terminal can receive the second indication information sent by the base station only when it determines that it needs to switch to another cell. Herein, the terminal switching to another cell may mean that the terminal initiates a process of switching to another cell but still camps on the base station.

[0206] When it is determined that the terminal switches to another cell, it indicates that the terminal leaves the cell of the base station and camps on the cell of another base station. Then the base station cannot send the positioning information to the terminal through the signaling. Therefore, in this case, the base station can fully determine that it fails to send the positioning information to the terminal and indicates to the terminal that it fails to send the positioning information through the second indication information.

[0207] In the case where the terminal does not switch to another cell, even if the terminal does not enter the disconnected state, since the terminal still camps on the cell of the base station, the base station still has an opportunity to send the signaling to the terminal later. Therefore, it cannot be determined that the positioning information sending fails, and thus the second indication information is not sent to the terminal.
