Description

Positioning measurement method and device Technical Field

The present application relates to the field of communication technology, and in particular to a positioning measurement method and device.

Background technique

In the case of satellite communications, since the signal transmission distance is long and the data transmission time is also long, for transmissions with uplink and downlink relationships, parameters for compensating transmission delay are introduced. The terminal device needs to obtain its own location information to facilitate uplink synchronization compensation.

In related technologies, terminal devices can obtain their own location information through global navigation satellite system (GNSS) measurement and report it to the network side. However, for the network side, the location information may be false or may be tampered with, and is unreliable. The network side can obtain the location information of the terminal device through multi-Round-Trip Time (multi-RTT). However, in the scenario of satellite movement (earth moving), the service time within a service cell may not meet the requirements of multiple RTT measurements, so RTT measurements between multiple service cells may be required to determine the location of the terminal device.

In order to better understand a positioning measurement method disclosed in an embodiment of the present application, the communication system to which the embodiment of the present application is applicable is first described below.

Please refer to Figure 1a, which is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. The communication system may include but is not limited to a network device and a terminal device. The number and form of the devices shown in Figure 1a are only used as examples and do not constitute a limitation on the embodiments of the present application. In actual applications, two or more network devices and two or more terminal devices may be included. The communication system shown in Figure 1a includes a network device 101, a terminal device 102 and a satellite 103 as an example.

It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems. For example: Long Term Evolution (LTE) system, fifth-generation mobile communication system, 5G new air interface system, or other future new mobile communication systems.

The network device 101 in the embodiment of the present application is an entity on the network side for transmitting or receiving signals. For example, the network device 101 may be an evolved NodeB (eNB), a transmission point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present application does not limit the specific technology and specific device form adopted by the network device. The network device provided in the embodiment of the present application may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit (Control Unit). The CU-DU structure may be used to split the protocol layer of a network device, such as a base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

The terminal device may also be referred to as a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be a car with communication function, a smart car, a mobile phone, an Internet of Things (IoT) terminal, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (Industrial Control), a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (Smart Grid), a wireless terminal device in transportation safety (Transportation Safety), a wireless terminal device in smart city (Smart City), a wireless terminal device in smart home (Smart Home), etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

With the continuous development of wireless communication technology, satellite communication is considered to be an important aspect of the future development of wireless communication technology. In the scenario of satellite communication, due to the long signal transmission distance between the transmitter and the receiver, data transmission has a large delay. For transmission with uplink and downlink relationships, the current standardization discussion has determined the introduction of offset Koffset parameters to compensate for transmission delays. As shown in Figures 1b and 1c, Figure 1b is a schematic diagram of the uplink and downlink timing alignment transmission method on the network device side, and Figure 1c is a schematic diagram of the uplink and downlink timing misalignment transmission method on the network device side.

The terminal device can compensate for the transmission delay through the ephemeris information and the common timing advance (common TA) information. The ephemeris information and common TA information are notified to the terminal device through the system information.

In the case of satellite communications, since the signal transmission distance is long and the data transmission time is also long, for transmissions with uplink and downlink relationships, parameters for compensating transmission delay are introduced. The terminal device needs to obtain its own location information to facilitate uplink synchronization compensation.

In related technologies, terminal devices can obtain their own location information through global navigation satellite system GNSS measurements and report it to the network side. However, for the network side, the location information may be false or may be tampered with, and is unreliable. The network side can obtain the location information of the terminal device through multi-station round-trip time delay multi-RTT to verify the location information based on GNSS measurement reported by the terminal device. However, in the scenario of satellite movement, the service cell where the terminal device is located may change, and the service time of the terminal device in a service cell may not meet the requirements of multiple RTT measurements. Therefore, RTT measurements between multiple service cells may be required to determine the location of the terminal device.

As an example of a satellite movement scenario, as shown in Figure 1d, Figure 1d is a schematic diagram of a satellite movement scenario provided in an embodiment of the present application. Due to the movement of the satellite, the service cell where the terminal device is located changes from service cell 1 to service cell 2.

It can be understood that the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application.

The positioning measurement method and device provided by the present application are described in detail below with reference to the accompanying drawings.

Please refer to Figure 2, which is a flow chart of a positioning measurement method provided in an embodiment of the present application. It should be noted that the positioning measurement method in the embodiment of the present application is performed by a core network device. The method can be performed independently or in combination with any other embodiment of the present application. As shown in Figure 2, the method may include the following steps:

Step 201: Receive satellite ephemeris information corresponding to at least one service cell sent by an access network device.

In an embodiment of the present application, the core network device is capable of receiving satellite ephemeris information corresponding to at least one service cell reported by the access network device.

In some implementations, one satellite may serve multiple service cells, and the core network device may receive the ephemeris information of the satellite corresponding to the multiple service cells sent by the access network device. The ephemeris information of the satellite corresponding to different service cells may be the same or different.

In some implementations, multiple satellites may serve multiple service cells, and the core network device can receive the ephemeris information of multiple satellites corresponding to the multiple service cells sent by the access network device, and the core network device can determine the ephemeris information of the satellite corresponding to each service cell.

Step 202: Send first indication information to the terminal device through the access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement.

In an embodiment of the present application, when the core network device needs to determine the location information of the terminal device, it can send first indication information to the terminal device through the access network device, and the first indication information is used to instruct the terminal device to perform positioning measurement.

Optionally, in the embodiment of the present application, the positioning measurement may be a multi-RTT-based positioning measurement.

Step 203: receiving, through the access network device, a positioning measurement result sent by the terminal device, the positioning measurement result including an identifier of a serving cell where the terminal device is located when performing the positioning measurement.

In an embodiment of the present application, the core network device can receive the positioning measurement result sent by the terminal device through the access network device, wherein the positioning measurement result includes the identifier of the service cell where the terminal device is located when performing the positioning measurement.

It can be understood that the positioning measurement result is information obtained after the terminal device performs positioning measurement.

In an embodiment of the present application, the core network device receives the identifier of the service cell and can determine the location information of the terminal device based on the satellite ephemeris information corresponding to the service cell.

In some embodiments, the positioning measurement result also includes first time information, and the first time information is used to indicate the time interval between the terminal device receiving a downlink pilot signal sent by an access network device when performing positioning measurement and sending an uplink pilot signal to the access network device.

In some embodiments, the service cell where the terminal device receives the downlink pilot signal sent by the access network device is different from the service cell where the terminal device sends the uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier when the terminal device receives the downlink pilot signal and the service cell identifier when the terminal device sends the uplink pilot signal.

In some implementations, the core network device can also send second indication information to the terminal device through the access network device, where the second indication information is used to indicate the time-frequency domain position of the terminal device to send the positioning measurement result.

In the embodiment of the present application, optionally, the downlink pilot signal may be a positioning reference signal (PRS), and the uplink pilot signal may be a channel sounding reference signal (SRS). It is understood that other appropriate uplink pilot signals and downlink pilot signals may be selected to complete the positioning measurement according to the actual application requirements.

In an embodiment of the present application, the core network device receives the positioning measurement result sent by the terminal device, and can calculate the location information of the terminal device according to the service cell identifier and the first time information included in the positioning measurement result.

It can be understood that in each embodiment of the present application, the interaction between the core network device and the terminal device is completed through the transit of the access network device.

In summary, by receiving satellite ephemeris information corresponding to at least one service cell sent by an access network device, sending first indication information to the terminal device through the access network device, the first indication information is used to instruct the terminal device to perform positioning measurement, and receiving the positioning measurement result sent by the terminal device through the access network device, the positioning measurement result includes the service cell identifier of the terminal device when the terminal device performs the positioning measurement. When one satellite supports multiple service cells or multiple satellites relay to serve one terminal device, the terminal device can be positioned, so that the network side can accurately obtain the location information of the terminal device, thereby verifying whether the terminal device is reliable, and effectively ensuring the stability of the communication system.

Please refer to Figure 3, which is a flow chart of a positioning measurement method provided in an embodiment of the present application. It should be noted that the positioning measurement method in the embodiment of the present application is performed by a core network device. The method can be performed independently or in combination with any other embodiment of the present application. As shown in Figure 3, the method may include the following steps:

Step 301: Receive satellite ephemeris information corresponding to at least one service cell sent by an access network device.

In an embodiment of the present application, the core network device is capable of receiving satellite ephemeris information corresponding to at least one service cell sent by the access network device, and the satellite ephemeris information may be ephemeris information of one or more satellites.

In some implementations, one satellite may serve multiple service cells, and the core network device may receive the ephemeris information of the satellite corresponding to the multiple service cells sent by the access network device. The ephemeris information of the satellite corresponding to different service cells may be the same or different.

In some implementations, multiple satellites may serve multiple service cells, and the core network device can receive the ephemeris information of multiple satellites corresponding to the multiple service cells sent by the access network device, and the core network device can determine the ephemeris information of the satellite corresponding to each service cell.

Step 302: Send first indication information to the terminal device through the access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement.

In an embodiment of the present application, when the core network device needs to determine the location information of the terminal device, it can send first indication information to the terminal device through the access network device, and the first indication information is used to instruct the terminal device to perform positioning measurement.

Optionally, in the embodiment of the present application, the positioning measurement may be a multi-RTT-based positioning measurement.

It should be noted that the terminal device performs multi-RTT-based positioning measurement including: the terminal device can receive the downlink pilot signal sent by the access network device, and after a period of time, the terminal device can send an uplink pilot signal to the access network device. The access network device can obtain the round-trip delay between the terminal device and the access network device, that is, the sum of the delay of the terminal device receiving the downlink pilot signal sent by the access network device, the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal, and the delay of the access network device receiving the uplink pilot signal sent by the terminal device.

It should also be noted that the transmission of signals between the terminal device and the access network device is based on satellite, that is, the pilot signal is received or sent through the satellite corresponding to the service cell.

It can be understood that the delay of the terminal device in receiving the downlink pilot signal sent by the access network device refers to the delay between the moment when the terminal device receives the downlink pilot signal and the moment when the access network device sends the downlink pilot signal; the delay of the access network device in receiving the uplink pilot signal sent by the terminal device refers to the delay between the moment when the access network device receives the uplink pilot signal and the moment when the terminal device sends the uplink pilot signal.

Step 303: receiving, through the access network device, a positioning measurement result sent by the terminal device, the positioning measurement result including an identifier of a serving cell where the terminal device performs positioning measurement, and first time information.

In an embodiment of the present application, a core network device can receive a positioning measurement result sent by a terminal device through an access network device, wherein the positioning measurement result includes an identifier of a serving cell where the terminal device performs the positioning measurement, and first time information.

The first time information is used to indicate the time interval between the terminal device receiving a downlink pilot signal sent by an access network device when performing positioning measurement and sending an uplink pilot signal to the access network device.

It can be understood that the positioning measurement result is information obtained after the terminal device performs positioning measurement.

In some embodiments, the service cell where the terminal device receives the downlink pilot signal sent by the access network device is different from the service cell where the terminal device sends the uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier when the terminal device receives the downlink pilot signal and the service cell identifier when the terminal device sends the uplink pilot signal.

As an example, as shown in FIG4a, the service cell where the terminal device is located when receiving the downlink pilot signal sent by the access network device is service cell 1, and the service cell where the terminal device is located when sending the uplink pilot signal to the access network device is service cell 2. Therefore, the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), downlink pilot signal: cell ID 1, uplink pilot signal: cell ID 2}. The first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal.

In some implementations, the service cell in which the terminal device receives a downlink pilot signal sent by the access network device is the same as the service cell in which the terminal device sends an uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier.

As an example, as shown in FIG4b, the service cell in which the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the service cell in which the terminal device is located when sending the uplink pilot signal to the access network device are both service cell 1. Therefore, the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), cell ID 1}. Among them, the first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal. Alternatively, as shown in FIG4c, the service cell in which the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the service cell in which the terminal device is located when sending the uplink pilot signal to the access network device are both service cell 2. Therefore, the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), cell ID 2}. Among them, the first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal.

In some implementations, the core network device can also send second indication information to the terminal device through the access network device, where the second indication information is used to indicate the time-frequency domain position of the terminal device to send the positioning measurement result.

In the embodiment of the present application, optionally, the downlink pilot signal may be a positioning reference signal PRS, and the uplink pilot signal may be a channel sounding reference signal SRS. It is understood that other appropriate uplink pilot signals and downlink pilot signals may be selected to complete positioning measurement according to actual application requirements.

It can be understood that in each embodiment of the present application, the interaction between the core network device and the terminal device is completed through the transit of the access network device.

Step 304: Determine the location information of the terminal device according to the positioning measurement result.

In an embodiment of the present application, the core network device receives the positioning measurement result sent by the terminal device, and can calculate the location information of the terminal device according to the service cell identifier and the first time information included in the positioning measurement result.

In some embodiments, the service cell in which the terminal device receives a downlink pilot signal sent by the access network device is different from the service cell in which the terminal device sends an uplink pilot signal to the access network device. The core network device can determine the satellite ephemeris information corresponding to the service cell in which the downlink pilot signal is received and the satellite ephemeris information corresponding to the service cell in which the uplink pilot signal is sent based on the service cell identifier for receiving the downlink pilot signal and the service cell identifier for sending the uplink pilot signal included in the positioning measurement result, and determine the moving trajectory of the satellite based on the acquired satellite ephemeris information corresponding to the two service cells, and further determine the location information of the terminal device based on the round-trip delay information and the first time information.

In some embodiments, the service cell where the terminal device receives the downlink pilot signal sent by the access network device is the same as the service cell where the terminal device sends the uplink pilot signal to the access network device. The core network device can determine the satellite ephemeris information corresponding to the service cell where the terminal device receives the downlink pilot signal and sends the uplink pilot signal based on the service cell identifier included in the positioning measurement result, and determine the moving trajectory of the satellite based on the acquired satellite ephemeris information, and further determine the location information of the terminal device based on the round-trip delay information and the first time information.

In summary, by receiving satellite ephemeris information corresponding to at least one service cell sent by an access network device, a first indication information is sent to a terminal device through the access network device, and the first indication information is used to instruct the terminal device to perform a positioning measurement. The positioning measurement result sent by the terminal device is received through the access network device, and the positioning measurement result includes a service cell identifier where the terminal device is located when the positioning measurement is performed, and the first time information. According to the positioning measurement result, the location information of the terminal device is determined, and the terminal device can be positioned when one satellite supports multiple service cells or multiple satellites relay to serve one terminal device, so that the network side can accurately obtain the location information of the terminal device, thereby verifying whether the terminal device is reliable, and effectively ensuring the stability of the communication system.

In some embodiments, the service cell where the terminal device receives the downlink pilot signal sent by the access network device is different from the service cell where the terminal device sends the uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier when the terminal device receives the downlink pilot signal and the service cell identifier when the terminal device sends the uplink pilot signal.

In some implementations, the terminal device can also receive second indication information sent by the core network device through the access network device, and the second indication information is used to indicate the time-frequency domain position at which the terminal device sends the positioning measurement result.

Please refer to Figure 6, which is a flow chart of a positioning measurement method provided in an embodiment of the present application. It should be noted that the positioning measurement method in the embodiment of the present application is performed by a terminal device. The method can be performed independently or in combination with any other embodiment of the present application. As shown in Figure 6, the method may include the following steps:

Step 601: Receive first indication information sent by a core network device through an access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement.

In an embodiment of the present application, when the core network device needs to determine the location information of the terminal device, it can send first indication information to the terminal device through the access network device. The terminal device can receive the first indication information sent by the core network device through the access network device, and can perform positioning measurement according to the indication of the first indication information.

Optionally, in the embodiment of the present application, the positioning measurement may be a multi-RTT-based positioning measurement.

It should be noted that the terminal device performs multi-RTT-based positioning measurement including: the terminal device can receive the downlink pilot signal sent by the access network device, and after a period of time, the terminal device can send an uplink pilot signal to the access network device. The access network device can obtain the round-trip delay between the terminal device and the access network device, that is, the sum of the delay of the terminal device receiving the downlink pilot signal sent by the access network device, the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal, and the delay of the access network device receiving the uplink pilot signal sent by the terminal device.

It should also be noted that the transmission of signals between the terminal device and the access network device is based on satellite, that is, the pilot signal is received or sent through the satellite corresponding to the service cell.

It can be understood that the delay of the terminal device in receiving the downlink pilot signal sent by the access network device refers to the delay between the moment when the terminal device receives the downlink pilot signal and the moment when the access network device sends the downlink pilot signal; the delay of the access network device in receiving the uplink pilot signal sent by the terminal device refers to the delay between the moment when the access network device receives the uplink pilot signal and the moment when the terminal device sends the uplink pilot signal.

Step 602: Receive a downlink pilot signal sent by the access network device.

In the embodiment of the present application, the terminal device performs positioning measurement and can receive a downlink pilot signal sent by the access network device. It can be understood that the downlink pilot signal is transmitted based on a satellite, that is, the access network device sends the downlink pilot signal to the terminal device via a service satellite.

Step 603: Send an uplink pilot signal to the access network device.

In the embodiment of the present application, the terminal device can send an uplink pilot signal to the access network device after receiving the downlink pilot signal for a period of time. It can be understood that the uplink pilot signal is also transmitted based on the satellite, that is, the terminal device sends the uplink pilot signal to the access network device through the service satellite.

In some implementations, the terminal device may determine the time unit for sending the uplink pilot signal according to the configuration of the access network device or the pre-defined provisions of the protocol, etc.

Step 604: Send the positioning measurement result to the core network device through the access network device, and the positioning measurement result includes the service cell identifier of the terminal device when performing the positioning measurement, and the first time information.

In an embodiment of the present application, after the terminal device performs the positioning measurement, the terminal device can send the positioning measurement result to the core network device through the access network device, wherein the positioning measurement result includes the identifier of the service cell where the terminal device is located when performing the positioning measurement, and the first time information.

The first time information is used to indicate the time interval between the terminal device receiving a downlink pilot signal sent by an access network device when performing positioning measurement and sending an uplink pilot signal to the access network device.

In some embodiments, the service cell where the terminal device receives the downlink pilot signal sent by the access network device is different from the service cell where the terminal device sends the uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier when the terminal device receives the downlink pilot signal and the service cell identifier when the terminal device sends the uplink pilot signal.

As an example, as shown in FIG4a, the service cell where the terminal device is located when receiving the downlink pilot signal sent by the access network device is service cell 1, and the service cell where the terminal device is located when sending the uplink pilot signal to the access network device is service cell 2, so the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), downlink pilot signal: cell ID 1, uplink pilot signal: cell ID 2}. The first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal.

In some implementations, the service cell in which the terminal device receives a downlink pilot signal sent by the access network device is the same as the service cell in which the terminal device sends an uplink pilot signal to the access network device, and the positioning measurement result includes the service cell identifier.

As an example, as shown in FIG4b, the service cell in which the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the service cell in which the terminal device is located when sending the uplink pilot signal to the access network device are both service cell 1. Therefore, the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), cell ID 1}. Among them, the first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal. Alternatively, as shown in FIG4c, the service cell in which the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the service cell in which the terminal device is located when sending the uplink pilot signal to the access network device are both service cell 2. Therefore, the positioning measurement result sent by the terminal device to the core network device includes: {first time information (Rx-Tx time), cell ID 2}. Among them, the first time information is the time interval between the terminal device receiving the downlink pilot signal and sending the uplink pilot signal.

In some implementations, the terminal device can also receive second indication information sent by the core network device through the access network device, and the second indication information is used to indicate the time-frequency domain position at which the terminal device sends the positioning measurement result. The terminal device sends the positioning measurement result at the time-frequency domain position indicated by the second indication information.

In the embodiment of the present application, optionally, the downlink pilot signal may be a positioning reference signal PRS, and the uplink pilot signal may be a channel sounding reference signal SRS. It is understood that other appropriate uplink pilot signals and downlink pilot signals may be selected to complete positioning measurement according to actual application requirements.

It can be understood that in each embodiment of the present application, the interaction between the core network device and the terminal device is completed through the transit of the access network device.

In summary, the first indication information sent by the core network device is received through the access network device, and the first indication information is used to instruct the terminal device to perform positioning measurement, receive the downlink pilot signal sent by the access network device, send an uplink pilot signal to the access network device, and send the positioning measurement result to the core network device through the access network device. The positioning measurement result includes the service cell identifier where the terminal device is located when the positioning measurement is performed, and the first time information. When one satellite supports multiple service cells or multiple satellites relay to serve one terminal device, the terminal device can be positioned, so that the network side can accurately obtain the location information of the terminal device, thereby verifying whether the terminal device is reliable, and effectively ensuring the stability of the communication system.

Step 704: Receive the positioning measurement result sent by the terminal device.

Step 705: Send the positioning measurement result to the core network device, where the positioning measurement result includes the serving cell identifier where the terminal device performs the positioning measurement.

It can be understood that steps 702 to 703 are for the access network device to complete the transfer of the positioning measurement results sent by the terminal device to the core network device.

The positioning measurement result includes the identifier of the service cell where the terminal device is located when performing the positioning measurement.

It can be understood that the positioning measurement result is information obtained after the terminal device performs positioning measurement.
