Description

Positioning measurement method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a positioning measurement method and apparatus.

Background

In the satellite communication scene, because the signal transmission distance is longer, the data transmission time is longer, and for the transmission with uplink and downlink relation, parameters for compensating the transmission delay are introduced. The terminal equipment needs to acquire own position information so as to facilitate uplink synchronization compensation.

In the related art, the terminal device may acquire its own location information by global navigation satellite system (global navigation satellite system, GNSS) measurement and report the location information to the network side, but the location information may be false or may be tampered with, which is unreliable for the network side. The network side may acquire location information of the terminal device through multi-station Round Trip Time (multi-RTT). However, in the scenario of satellite movement (earth moving), the service time within one serving cell may not meet the requirement of multiple RTT measurements, and thus RTT measurements between multiple serving cells may be required to determine the location of the terminal device.

In order to better understand a positioning measurement method disclosed in the embodiments of the present application, a description is first given below of a communication system to which the embodiments of the present application are applicable.

Referring to fig. 1a, fig. 1a is a schematic architecture diagram of a communication system according to an embodiment of the present application. The communication system may include, but is not limited to, one network device and one terminal device, and the number and form of devices shown in fig. 1a are only used as examples and not limiting to the embodiments of the present application, and in practical applications, two or more network devices and two or more terminal devices may be included. The communication system shown in fig. 1a comprises, for example, a network device 101, a terminal device 102 and a satellite 103.

It should be noted that the technical solution of the embodiment of the present application may be applied to various communication systems. For example: a long term evolution (Long Term Evolution, LTE) system, a fifth generation mobile communication system, a 5G new air interface system, or other future new mobile communication systems, etc.

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 and may be an Evolved NodeB (eNB), a transmission point (Transmission Reception 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 (Wireless Fidelity, wiFi) system, etc. The embodiment of the application does not limit the specific technology and the specific device form adopted by the network device. The network device provided in this embodiment of the present application may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a Control Unit (Control Unit), and the structure of the CU-DU may be used to split the protocol layers of the network device, for example, a base station, where functions of part of the protocol layers are placed in the CU for centralized Control, and functions of part or all of the protocol layers are Distributed in the DU for centralized Control of the DU by the CU.

The Terminal device may also be referred to as a Terminal device (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal device (MT), etc. The terminal device may be an automobile with communication function, a Smart car, a Mobile Phone (Mobile Phone), an internet of things (Internet of Things, ioT) terminal, a wearable device, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal device, an augmented Reality (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 teleoperation (Remote Medical Surgery), a wireless terminal device in Smart Grid (Smart Grid), a wireless terminal device in transportation security (Transportation Safety), a wireless terminal device in Smart City (Smart City), a wireless terminal device in Smart Home (Smart Home), and the like. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the terminal equipment.

With the continuous development of wireless communication technology, satellite communication is considered as an important aspect of future development of wireless communication technology. In the satellite communication scenario, the data transmission has a larger delay due to a longer signal transmission distance between the transmitting end and the receiving end. For transmissions with uplink and downlink relationships, the current standardization discussion determines parameters that introduce an offset Koffset to compensate for the transmission delay. As shown in fig. 1b and fig. 1c, fig. 1b is a schematic diagram of uplink and downlink timing alignment transmission modes at the network device side, and fig. 1c is a schematic diagram of uplink and downlink timing misalignment transmission modes at the network device side.

The terminal device may compensate for the transmission delay by means of ephemeris information and information about the common timing advance (common timing advance, common TA). The ephemeris information and common TA information are notified to the terminal device through the system information.

In the related art, the terminal device may obtain its own position information by GNSS measurement and report the position information to the network side, but the position information may be false or may be tampered with, which is unreliable for the network side. The network side can acquire the position information of the terminal equipment through multi-station round trip time delay multi-RTT so as to verify the position information based on GNSS measurement and reported by the terminal equipment. However, in the satellite mobile scenario, the serving cell in which the terminal device is located may change, and the service time of the terminal device in one serving cell may not meet the requirement of multiple RTT measurements, so that RTT measurements between multiple serving cells may be required to determine the location of the terminal device.

As an example of a satellite moving scenario, as shown in fig. 1d, fig. 1d is a schematic view of a satellite moving scenario provided in an embodiment of the present application, and a serving cell in which a terminal device is located changes from serving cell 1 to serving cell 2 due to movement of a satellite.

It may be understood that, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and is not limited to the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

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

Referring to fig. 2, fig. 2 is a flow chart of a positioning measurement method according to an embodiment of the present application. It should be noted that, the positioning measurement method in the embodiment of the present application is executed by the core network device. The method may be performed independently or in combination with any of the other embodiments of the present application. As shown in fig. 2, the method may include the steps of:

step 201, satellite ephemeris information corresponding to at least one service cell sent by an access network device is received.

In the embodiment of the application, the core network device can receive satellite ephemeris information corresponding to at least one service cell reported by the access network device.

In some embodiments, a satellite may serve multiple service cells, and the core network device may be capable of receiving ephemeris information of the satellite corresponding to the multiple service cells sent by the access network device, where the ephemeris information of the satellite corresponding to different service cells may be the same or different.

In some embodiments, the core network device may be configured to receive ephemeris information of a plurality of satellites corresponding to a plurality of service cells sent by the access network device, where the core network device may be configured to determine the ephemeris information of the satellites corresponding to each service cell.

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

In the embodiment of the application, when the core network device needs to determine the position information of the terminal device, the first indication information can be sent to the terminal device through the access network device, and the first indication information is used for indicating the terminal device to execute positioning measurement.

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

And 203, receiving, by the access network device, a positioning measurement result sent by the terminal device, where the positioning measurement result includes a serving cell identifier where the terminal device performs positioning measurement.

In the embodiment of the 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 comprises the identifier of the serving cell where the terminal device is located when performing positioning measurement.

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

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

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

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

In some embodiments, the core network device is further capable of sending second indication information to the terminal device through the access network device, where the second indication information is used to indicate a time-frequency domain location where the terminal device sends the positioning measurement result.

In an embodiment of the present application, optionally, the downlink pilot signal may be a positioning reference signal (Positioning Reference Signal, PRS), and the uplink pilot signal may be a channel sounding reference signal (Sounding Reference Signal, SRS). It will be appreciated that other suitable uplink pilot signals and downlink pilot signals may be selected to perform positioning measurements according to practical application requirements.

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

It will be appreciated that in embodiments of the present application, the interaction between the core network device and the terminal device is accomplished 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 a terminal device by the access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement, and receiving, by the access network device, a positioning measurement result sent by the terminal device, where the positioning measurement result includes a service cell identifier where the terminal device is located when performing positioning measurement, positioning of the terminal device can be implemented under a condition that one satellite supports multiple service cells or is a terminal device served by multiple satellites in relay, so that a network side can accurately obtain position information of the terminal device, thereby verifying whether the terminal device is reliable or not, and effectively guaranteeing stability of a communication system.

Referring to fig. 3, fig. 3 is a flow chart of a positioning measurement method according to an embodiment of the present application. It should be noted that, the positioning measurement method in the embodiment of the present application is executed by the core network device. The method may be performed independently or in combination with any of the other embodiments of the present application. As shown in fig. 3, the method may include the steps of:

step 301, satellite ephemeris information corresponding to at least one service cell sent by an access network device is received.

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

Step 302, sending, by an access network device, first indication information to a terminal device, where the first indication information is used to instruct the terminal device to perform positioning measurement.

It should be noted that, the terminal device performing positioning measurement based on multi-RTT includes: 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 the 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.

In addition, the transmission of signals between the terminal device and the access network device is satellite-based, that is, the pilot signals are received or transmitted via the satellite corresponding to the serving cell.

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

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

In the embodiment of the application, the core network device can receive a positioning measurement result sent by the terminal device through the access network device, wherein the positioning measurement result comprises an identifier of a serving cell where the terminal device is located when performing positioning measurement and first time information.

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

As an example, as shown in fig. 4a, the serving cell where the terminal device is located when receiving the downlink pilot signal sent by the access network device is serving cell 1, and the serving cell where the terminal device is located when sending the uplink pilot signal to the access network device is serving 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: cell ID1, uplink pilot signal: cell ID 2}. The first time information is a time interval between the terminal device receiving the downlink pilot signal and transmitting the uplink pilot signal.

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

As an example, as shown in fig. 4b, the serving cell where the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the serving cell where the terminal device is located when sending the uplink pilot signal to the access network device are both serving cell 1. The positioning measurement result sent by the terminal device to the core network device includes: { first time information (Rx-Tx time), cell ID 1}. The first time information is a time interval between the terminal device receiving the downlink pilot signal and transmitting the uplink pilot signal. Or as shown in fig. 4c, the serving cell where the terminal device is located when receiving the downlink pilot signal sent by the access network device, and the serving cell where the terminal device is located when sending the uplink pilot signal to the access network device are both serving cell 2. The positioning measurement result sent by the terminal device to the core network device includes: { first time information (Rx-Tx time), cell ID 2}. The first time information is a time interval between the terminal device receiving the downlink pilot signal and transmitting the uplink pilot signal.

In this 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 will be appreciated that other suitable uplink pilot signals and downlink pilot signals may be selected to perform positioning measurements according to practical application requirements.

Step 304, determining the location information of the terminal device according to the location measurement result.

In some embodiments, the serving cell where the terminal device receives the downlink pilot signal sent by the access network device is different from the serving cell where the terminal device sends the uplink pilot signal to the access network device, and the core network device can determine, according to the serving cell identifier for receiving the downlink pilot signal and the serving cell identifier for sending the uplink pilot signal included in the positioning measurement result, satellite ephemeris information corresponding to the serving cell where the downlink pilot signal is received and satellite ephemeris information corresponding to the serving cell where the uplink pilot signal is sent, determine a movement track of a satellite according to the obtained satellite ephemeris information corresponding to the two serving cells, and further determine location information of the terminal device according to round trip delay information and first time information.

In some embodiments, the serving cell where the terminal device receives the downlink pilot signal sent by the access network device is the same as the serving cell where the terminal device sends the uplink pilot signal to the access network device, and the core network device can determine satellite ephemeris information corresponding to the serving cell where the terminal device receives the downlink pilot signal and sends the uplink pilot signal according to the serving cell identifier included in the positioning measurement result, determine a movement track of a satellite according to the obtained satellite ephemeris information, and further determine location information of the terminal device according to round trip delay information and first time information.

In summary, by receiving satellite ephemeris information corresponding to at least one serving cell sent by an access network device, sending first indication information to a terminal device by the access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement, receiving, by the access network device, a positioning measurement result sent by the terminal device, where the positioning measurement result includes a serving cell identifier where the terminal device performs positioning measurement, and first time information, and determining, according to the positioning measurement result, location information of the terminal device, where one satellite supports multiple serving cells or is multiple satellite relay services for one terminal device, location of the terminal device can be implemented, so that a network side can accurately obtain location information of the terminal device, thereby verifying whether the terminal device is reliable, and effectively guaranteeing stability of a communication system.

In the embodiment of the present application, the serving cell identifier is used for determining, by the core network device, location information of the terminal device based on satellite ephemeris information corresponding to the serving cell.

In some embodiments, the terminal device is further capable of receiving, through the access network device, second indication information sent by the core network device, where the second indication information is used to indicate a time-frequency domain location where the terminal device sends the positioning measurement result. And the terminal equipment sends the positioning measurement result at the time-frequency domain position indicated by the second indication information.

In summary, the first indication information sent by the core network device is received through the access network device, where the first indication information is used to instruct the terminal device to perform positioning measurement, and the positioning measurement result is sent to the core network device through the access network device, where the positioning measurement result includes a service cell identifier where the terminal device performs positioning measurement, so that positioning of the terminal device can be implemented under the condition that one satellite supports multiple service cells or one terminal device is served by multiple satellites in relay, and the network side can accurately obtain the position information of the terminal device, thereby verifying whether the terminal device is reliable or not, and effectively guaranteeing the stability of the communication system.
