[0002] 5G (5th generation mobile networks) Release 16 (R16) introduces various terminal positioning technologies, all of which can achieve terminal location.

[0104] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0105] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones, and computers with IoT user equipment capabilities. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device.

Alternatively, user equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0106] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system; or it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network).

[0107] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack.

[0108] Base station 120 and user equipment 110 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0110] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.

[0111] In some embodiments, the wireless communication system described above may further include a network management device 130.

[0112] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0113] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0114] To better understand the technical solutions disclosed in the embodiments of this disclosure, the application scenarios of terminal positioning are described below:

[0115] In one embodiment, when the positioning server requests the terminal to perform location-related measurements (e.g., Reference Signal Time Difference (RSTD) measurement), if the terminal needs a measurement gap to complete the measurement, the terminal needs to report the positioning measurement configuration information of the measurement gap to the serving cell, and then the serving cell configures the measurement gap according to the reported positioning measurement configuration information.

[0116] In one embodiment, see Figure 2 The positioning and measurement process includes:

[0117] Step 1a: The positioning server sends an LTE Positioning Protocol (LPP) request capability message to the terminal;

[0118] Step 2a: The terminal sends an LPP Provide Capabilities message to the positioning server;

[0119] Step 3a: The positioning server sends an LPP (Provide Assistance Data) message to the terminal;

[0120] Step 4a: The location server sends an LPP request location information message to the terminal;

[0121] Step 5a: The terminal performs RSTD measurement within the response time;

[0122] Step 6a: The terminal sends an LPP (Provide Location Information) message to the location server.

[0123] In one embodiment, see Figure 3 The process by which the terminal reports the positioning measurement configuration information of the measurement gap to the cell includes:

[0124] Step 1b: The terminal sends an RSTD measurement indication (InterFreqRSTDMeasurementIndication) to the base station. Here, the RSTD measurement indication may include positioning measurement configuration information.

[0125] The above process has a relatively long measurement delay. In order to improve the efficiency and performance of positioning measurement, it is necessary to study a process that reduces the positioning measurement delay.

[0126] like Figure 4 As shown, this embodiment provides a positioning measurement method, wherein the method is executed by a positioning server, and the method includes:

[0127] Step 41: Send measurement assistance information to the terminal's serving base station, wherein the measurement assistance information is used by the serving base station to determine the measurement gap for the terminal to perform positioning measurements using a predetermined method.

[0128] Here, the location server can be a core network device. It can be a Location Management Function (LMF) within the core network. It should be noted that the location server can also be other functional entities within the core network.

[0129] Here, the terminal can be a device with wireless transceiver capabilities. The terminal can be, but is not limited to, a mobile phone, tablet computer, wearable device, vehicle terminal, roadside unit (RSU), smart home terminal, industrial sensing device, and / or medical device. The terminal can be deployed on land, at sea (e.g., on a ship), or in the air (e.g., on an airplane, balloon, or satellite).

[0130] Here, the serving base station and the base station involved in this application are interface devices for terminal access to the network. The base station can be of various types, such as a base station for a third-generation mobile communication (3G) network, a base station for a fourth-generation mobile communication (4G) network, a base station for a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0131] In one embodiment, positioning measurement can involve the terminal measuring Positioning Reference Signals (PRS) transmitted by different base stations to obtain the Time of Arrival (TOA) or Time Difference of Arrival (TDOA) of the PRS transmitted by different base stations. Combined with the location coordinates of each base station, the terminal's coordinates are calculated. It should be noted that the terminal needs to measure the PRS within the time period indicated by the measurement interval.

[0132] In one embodiment, see Figure 5 The diagram illustrates a terminal performing positioning measurements. The terminal calculates the relative difference in transmission delay between each base station and the terminal based on the difference between the time it receives positioning reference signals from three or more base stations (e.g., three base stations: base station 1, base station 2, and base station 3) and the time it receives the positioning reference signals from those base stations. The terminal's position is then calculated using this relative difference in transmission delay and the location coordinates of the base stations. Here, the positioning reference signals sent by each base station to the terminal can be downlink positioning reference signals (PRS).

[0133] In one embodiment, the measurement assistance information may be configuration information for configuring the terminal to perform positioning measurements. This can be a New Radio Positioning Protocol (NRPPa) message sent by the positioning server to the serving base station of the terminal. The NRPPa message is a wireless communication message based on NRPPa. The NRPPa message may carry measurement assistance information. This information includes information indicating a predetermined method and information about the measurement interval. Upon receiving the measurement assistance information, the serving base station can determine the measurement interval for the terminal to perform positioning measurements using the predetermined method indicated by the predetermined method information. Here, the positioning method may be an RSTD-based positioning method. The measurement interval may include a start point and an end point. For example, the start point may be the 1st second, and the end point may be the 3rd second. In another embodiment, the measurement interval may include a start point and a duration. For example, the start point may be the 1st second, and the duration may be 5ms, 5.5ms, 6ms, 6.5ms, and 7ms, etc. In one embodiment, the serving base station sends the measurement interval information to the terminal. After determining the measurement interval, the terminal performs positioning measurements within that interval.

[0134] In one embodiment, the New Radio Positioning Protocol (NRPPa) message sent by the positioning server to the serving base station of the terminal includes measurement assistance information. Upon receiving the NRPPa message, the serving base station determines a Radio Resource Control (RRC) message based on the NRPPa message and sends the RRC message to the terminal. Here, the RRC message includes measurement gaps. These measurement gaps in the RRC message are determined based on the measurement assistance information in the NRPPa message.

[0135] In one embodiment, the positioning server sends measurement assistance information to the terminal simultaneously with sending the measurement assistance information to the terminal's serving base station. This measurement assistance information can be sent to the terminal using an LPP message.

[0136] In one embodiment, the measurement assistance information includes measurement reference cell configuration information and / or neighboring cell configuration information. Here, the reference cell and / or neighboring cell can be cells used for positioning. The measurement assistance information can also indicate the accuracy information of the PRS transmitted by the base station, the altitude information of the transmission point of the PRS transmitted by the base station, and the coordinate information of the location of the base station, etc. The terminal can combine the positioning assistance information to more accurately determine the signal strength and / or reception time information of the received positioning reference signal, thereby obtaining a more accurate positioning result. In one embodiment, the measurement assistance information can also indicate the configuration information of multiple positioning methods for the terminal to perform positioning measurements. After receiving the positioning assistance information, the terminal selects one positioning method from multiple positioning methods and performs positioning according to the configuration information corresponding to the selected positioning method indicated by the positioning assistance information. In one embodiment, the measurement assistance information can also indicate the time-frequency domain position of the positioning reference signal transmitted by the base station. In this way, the terminal can receive the positioning reference signal at the corresponding time-frequency domain position according to the indication of the positioning assistance information.

[0137] In one embodiment, when the positioning server receives a request to perform positioning measurements on the terminal, it sends measurement assistance information to the terminal's serving base station. For example, when the positioning server receives a request to perform positioning and tracking on the terminal, it sends measurement assistance information to the terminal's serving base station in response to the positioning and tracking request.

[0138] In one embodiment, when the positioning server receives a request from the terminal via the access network to perform positioning measurements on the terminal, it sends measurement assistance information to the terminal's serving base station. For example, if the terminal needs to know the coordinates of its location, it sends a positioning measurement request to the positioning server via the access network. After receiving the positioning measurement request, the core network element sends measurement assistance information to the terminal's serving base station.

[0139] In one embodiment, before sending measurement assistance information to the terminal's serving base station, the positioning server also sends a positioning measurement capability request to the terminal. This capability request requests whether the terminal supports or does not support positioning measurement using a predetermined method. The positioning server receives feedback information from the terminal in response to the capability request, indicating whether the terminal supports or does not support positioning measurement using the predetermined method. If the feedback indicates that the terminal supports positioning measurement using the predetermined method, the positioning server sends measurement assistance information to the terminal's serving base station. If the feedback indicates that the terminal does not support positioning measurement using the predetermined method, the positioning server does not send measurement assistance information to the terminal's serving base station. It should be noted that if the feedback indicates that the terminal does not support positioning measurement using the predetermined method, the positioning server will not send measurement assistance information to the terminal either.

[0140] In one embodiment, the feedback information sent by the terminal to the positioning server includes the cell identifier indicating the serving base station. In this way, the positioning server can send measurement assistance information to the base station indicated by the cell identifier.

[0141] In one embodiment, the feedback information may also include at least one of the following:

[0142] Information on the supported reservation methods;

[0143] Supported frequency band information;

[0144] Information indicating whether the reservation method is supported or not.

[0145] In one embodiment, after sending measurement assistance information to the terminal's serving base station, the positioning server also sends a location information request message to the terminal for positioning measurement. This location information request message triggers the terminal to perform positioning measurement using a predetermined method. Upon receiving the location information request message, the terminal performs the positioning measurement.

[0146] In this embodiment, measurement assistance information is sent to the serving base station of the terminal. This measurement assistance information is used by the serving base station to determine the measurement interval for the terminal to perform positioning measurements using a predetermined method. Here, the positioning server can directly send the measurement assistance information to the terminal's serving base station. After receiving the measurement assistance information, the terminal's serving base station can determine the measurement interval for the terminal to perform positioning measurements using the predetermined method. Compared to the method where the positioning server needs to send the measurement assistance information to the terminal and then the terminal sends it to the serving base station, this reduces the latency of the measurement assistance information transmission. Thus, the latency of the terminal positioning technology can be reduced, improving the user experience.

[0147] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0148] like Figure 6 As shown, this embodiment provides a positioning measurement method, wherein the method is executed by a positioning server, and the method includes:

[0149] Step 61: Send measurement assistance information to the serving base station using the auxiliary data message.

[0150] In one embodiment, NRPPa is used to provide auxiliary data messages to send measurement assistance information to the serving base station.

[0151] In one embodiment, the NRPPa message sent by the positioning server to the serving base station of the terminal includes measurement assistance information. Upon receiving the NRPPa message, the serving base station determines an RRC message based on the NRPPa message and sends the RRC message to the terminal. Here, the RRC message includes a measurement gap. The measurement gap in the RRC message is determined based on the measurement assistance information in the NRPPa message.

[0152] In one embodiment, when the positioning server receives a request to perform positioning measurements on the terminal, it may use NRPPa to provide auxiliary data messages and send measurement assistance information to the serving base station. In another embodiment, when the positioning server receives a request from the terminal via the access network to perform positioning measurements on the terminal, it may use NRPPa to provide auxiliary data messages and send measurement assistance information to the serving base station.

[0153] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0154] like Figure 7 As shown, this embodiment provides a positioning measurement method, wherein the method is executed by a positioning server, and the method includes:

[0155] Step 71: Send a positioning measurement capability request information to the terminal, wherein the capability request information is used to request the terminal to support or not support the capability of positioning measurement using a predetermined method.

[0156] In one embodiment, the positioning server may send a positioning measurement capability request to the terminal when it receives a request to perform positioning measurements on the terminal. In another embodiment, the positioning server may send the positioning measurement capability request to the terminal when it receives a request from the terminal via the access network to perform positioning measurements on the terminal.

[0157] In one embodiment, after sending a location measurement capability request to the terminal, the location server receives feedback information from the terminal in response to the capability request. This feedback information indicates whether the terminal supports or does not support location measurement using a predetermined method. If the feedback information indicates that the terminal supports location measurement using the predetermined method, the location server sends measurement assistance information to the terminal's serving base station. If the feedback information indicates that the terminal does not support location measurement using the predetermined method, the location server does not send measurement assistance information to the terminal's serving base station.

[0158] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0159] like Figure 8 As shown, this embodiment provides a positioning measurement method, wherein the method is executed by a positioning server, and the method includes:

[0160] Step 81: Send a capability request message for positioning measurement to the terminal using the capability request message.

[0161] In one embodiment, a location measurement capability request message may be sent to the terminal using an LPP capability request message.

[0191] Step 131: Receive measurement assistance information sent by the positioning server, wherein the measurement assistance information is used by the base station to determine the measurement gap for the terminal to perform positioning measurement in a predetermined manner.

[0192] Here, the location server can be a core network device. The location server can be a Location Management Function (LMF) within the core network. It should be noted that the location server can also be other functional entities within the core network.

The base station can be of various types, such as a base station for a third-generation mobile communication (3G) network, a base station for a fourth-generation mobile communication (4G) network, a base station for a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0195] In one embodiment, positioning measurement can involve the terminal measuring Positioning Reference Signals (PRS) transmitted by different base stations to obtain the Time of Arrival (TOA) or Time Difference of Arrival (TDOA) of the PRS transmitted by different base stations. Combined with the location coordinates of each base station, the terminal's coordinates are calculated. It should be noted that the terminal needs to measure the PRS within the time period indicated by the measurement interval.

[0196] In one embodiment, see Figure 5 The diagram illustrates a terminal performing positioning measurements. The terminal calculates the relative difference in transmission delay between each base station and the terminal based on the difference between the time it receives positioning reference signals from three or more base stations (e.g., three base stations: base station 1, base station 2, and base station 3) and the time it receives the positioning reference signals from those base stations. The terminal's position is then calculated using this relative difference in transmission delay and the location coordinates of the base stations.

In one embodiment, the measurement assistance information can also indicate the configuration information of multiple positioning methods for the terminal to perform positioning measurements. After receiving the positioning assistance information, the terminal selects one positioning method from multiple positioning methods and performs positioning according to the configuration information corresponding to the selected positioning method indicated by the positioning assistance information. In one embodiment, the measurement assistance information can also indicate the time-frequency domain position of the positioning reference signal transmitted by the base station. In this way, the terminal can receive the positioning reference signal at the corresponding time-frequency domain position according to the indication of the positioning assistance information.

[0202] In one embodiment, when the positioning server receives a request from the terminal via the access network to perform positioning measurements on the terminal, it sends measurement assistance information to the terminal's serving base station. For example, if the terminal needs to know the coordinates of its location, it sends a positioning measurement request to the positioning server via the access network. After receiving the positioning measurement request, the core network element sends measurement assistance information to the terminal's serving base station.

[0203] In one embodiment, before sending measurement assistance information to the terminal's serving base station, the positioning server also sends a positioning measurement capability request to the terminal. This capability request requests whether the terminal supports or does not support positioning measurement using a predetermined method. The positioning server receives feedback information from the terminal in response to the capability request, indicating whether the terminal supports or does not support positioning measurement using the predetermined method. If the feedback indicates that the terminal supports positioning measurement using the predetermined method, the positioning server sends measurement assistance information to the terminal's serving base station. If the feedback indicates that the terminal does not support positioning measurement using the predetermined method, the positioning server does not send measurement assistance information to the terminal's serving base station.
