[0057] The following is a brief introduction to some of the technical aspects involved in this application.

[0058] (1) Non-Terrestrial Network (NTN)

[0059] The 3rd Generation Partnership Project (3GPP) defines NTN as "a network or network segment that uses airborne or space-based vehicles to carry transmission equipment, relay nodes, or base stations." Simply put, it's a general term for any network involving non-terrestrial flying objects, including satellite communication networks and High Altitude Platform (HAP) systems. NTN allows traditional 3GPP terrestrial networks to break through the limitations of the ground and extend into natural spaces such as the air, sea, and land. Since the current focus of 3GPP work is on satellite communication networks, NTN in a narrower sense primarily refers to satellite communication.

[0060] (2) Connected-state GNSS measurements

[0061] In NTN scenarios, terminals need to perform GNSS measurements to obtain GNSS positioning. In R17 Internet of Things NTN (IoT-NTN), simultaneous GNSS measurement and Narrow Band Internet of Things (NB-IoT) / enhanced machine-type communication (eMTC) data transmission are not supported. Terminals can only perform GNSS measurements in RRC_IDLE mode. If the terminal's GNSS positioning is outdated, the terminal must enter RRC_IDLE mode to perform GNSS measurement. To enable terminals in RRC_IDLE mode to perform GNSS measurements, R18 IoT-NTN introduces two mechanisms: network-triggered GNSS measurement and automatic GNSS measurement.

[0062] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application. The wireless communication system includes a terminal 11, a satellite 12, and an NTN gateway 13. The terminal 11 communicates with the satellite 12 via a service link, the satellite 12 communicates with the NTN gateway 13 via a feeder link, and the NTN gateway 13 communicates with a data network. It should be noted that the number of communication devices in the wireless communication system shown in Figure 1 is only for illustrative purposes; the number of communication devices can be multiple, and the connection relationships can be changed according to actual circumstances. The example in Figure 1 is not intended to limit the wireless communication system provided in the embodiments of this application. For example, only one terminal 11 is shown in Figure 1; in some embodiments, the wireless communication system shown in Figure 1 may have more terminals 11 communicating with the satellite 12.

[0063] Terminal 11 can be a mobile phone, tablet computer, laptop computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. The vehicle-mounted equipment can also be referred to as a vehicle-mounted terminal, vehicle-mounted controller, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip, or vehicle-mounted unit, etc. It should be noted that the specific type of terminal 11 is not limited in the embodiments of this application.

[0064] The GNSS measurement method, terminal, network-side equipment, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0065] It should be noted that the various embodiments of this application can be applied to non-terrestrial network (NTN) scenarios, as well as other scenarios that require GNSS measurements, such as terrestrial network scenarios and integrated air-space scenarios.

[0066] Please refer to Figure 2. This embodiment of the application provides a GNSS measurement method, including:

[0067] Step 21: If the first condition is met, the terminal performs GNSS measurements;

[0068] The first condition includes any one of the following:

[0069] The terminal receives a first instruction and a first time information sent by the network-side device;

[0070] The terminal receives a first instruction sent by the network-side device;

[0071] The terminal receives the first real-time information sent by the network-side device;

[0072] Wherein, the first indication is used to instruct the network-side device to enable the GNSS measurement of the terminal, and the first time information is the time information of the terminal performing GNSS measurement.

[0073] In this embodiment of the application, GNSS measurement can also be referred to as GNSS acquisition or GNSS reacquisition, that is, the acquisition or reacquisition of GNSS positioning.

[0074] The terminal performing GNSS measurements can also be understood as the terminal being enabled to perform GNSS measurements.

[0075] Optionally, in this embodiment, the terminal performs GNSS measurements when it is in RRC connected state and meets the first condition. That is, the terminal can be in RRC connected state and has the capability to perform GNSS measurements in connected state. In this embodiment, the GNSS measurement can be a GNSS measurement performed by the terminal in RRC connected state.

[0076] In this application example, optionally, the network-side device can be a network-side device in an NTN network, such as a satellite, drone, aircraft, or a ground base station connected to a satellite.

[0077] In this embodiment of the application, the first instruction can be gnss-AutonomousEnabled.

[0078] Optionally, the first indication can be carried via an RRC message. The RRC message may include at least one of the following: an RRC connection setup message, an RRC connection resume message, an RRC connection re-establishment message, or an RRC connection reconfiguration message.

[0079] In this embodiment of the application, optionally, the first time information is the time required for GNSS measurement reported by the terminal, which is the time information configured by the network-side device for performing GNSS measurement. Optionally, the first time information includes time length information, wherein the time length information in the first time information is greater than or equal to the time required for GNSS measurement reported by the terminal, so as to meet the time requirements for the terminal to perform GNSS measurement. In this embodiment of the application, optionally, the terminal performing GNSS measurement can also be described as the GNSS measurement function being activated.

[0080] Optionally, in this embodiment, the terminal does not perform GNSS measurements, which can also be described as the GNSS measurement function not being activated. It is understood that the terminal not performing GNSS measurements includes not performing automatic GNSS measurements and network-triggered GNSS measurements, not performing automatic GNSS measurements, and not performing network-triggered GNSS measurements.

[0081] In this application embodiment, it is clarified when the terminal can perform GNSS measurement, or when the GNSS measurement function is activated, so that the terminal can perform GNSS measurement in a timely manner and avoid communication failure caused by outdated GNSS positioning.

[0082] In this embodiment of the application, optionally, the first time information is carried via an RRC message or a MAC CE. The MAC CE may include a GNSS Measurement Command MAC CE. The RRC message may include at least one of the following: an RRC connection setup message, an RRC connection recovery message, an RRC connection re-establishment message, or an RRC connection reconfiguration message.

[0083] Optionally, in this embodiment of the application, the first time information includes time length information, that is, the terminal can perform GNSS measurements within the time length.

[0084] In this embodiment of the application, optionally, the first time information is timer information, time interval information, time window information, or period information. When the first time information includes timer information, the timer information may include the length of the timer. The timer is started when the terminal performs GNSS measurement. If the timer does not time out and the terminal completes the GNSS measurement, the timer stops; if the timer times out but the terminal does not complete the GNSS measurement, the GNSS measurement is considered to have failed.

[0085] Optionally, in this embodiment of the application, if the first condition includes the terminal receiving a first instruction and a first time information sent by the network-side device, the method further includes: if the terminal receives the first instruction sent by the network-side device but does not receive the first time information sent by the network-side device, the terminal does not perform the GNSS measurement. In other words, the terminal is not enabled to perform GNSS measurement or the GNSS measurement enablement is not applied. That is, in this embodiment of the application, the terminal does not activate the GNSS measurement function upon receiving only the first instruction, but waits until the first time information is received before activating the GNSS measurement function.

[0086] Therefore, when the terminal can perform GNSS measurements, the embodiments of this application provide a specific scheme for the terminal to acquire time information and perform GNSS measurements based on the time information.

[0087] The process of a terminal performing GNSS measurements is as follows: The terminal receives signals transmitted to the ground by satellites at precise time intervals. The satellite's position can be found in the satellite ephemeris, and the distance from the terminal to the satellite can be obtained by multiplying the time it takes for the signal to travel from the satellite to the user by the speed of light. By combining data from multiple satellites, the terminal's position, i.e., GNSS positioning, can be obtained. Due to the mobility of the terminal and satellites, GNSS positioning usually has a valid time frame; after this time frame, the GNSS positioning is considered invalid or outdated.

[0088] Optionally, in this embodiment of the application, the GNSS measurement method further includes: when the terminal does not perform GNSS measurement and the GNSS positioning of the terminal is out-of-date, the terminal performs at least one of the following operations:

[0089] Leaving the RRC connection state;

[0090] Enter the RRC idle state (RRC_IDLE).

[0091] In this application embodiment, GNSS positioning being outdated can also be described as GNSS positioning being invalid.

[0092] Since GNSS positioning is outdated and the terminal cannot perform GNSS measurements, the terminal needs to leave the RRC connected state and enter the RRC idle state.

[0093] Optionally, in this embodiment of the application, if the first condition includes the terminal receiving a first instruction and first time information sent by the network-side device, the method further includes: the terminal performing GNSS measurement based on the first time information.

[0094] Optionally, the terminal performs GNSS measurements based on the time length information indicated by the first time information. That is, the terminal can perform GNSS measurements using the time length information. It is understood that the terminal can perform GNSS measurements within the time period indicated by the time length information. If the terminal completes the GNSS measurement within the time period indicated by the time length information, the terminal can trigger the process of reporting the valid GNSS duration. If the terminal does not complete the GNSS measurement within the time period indicated by the time length information, the GNSS measurement is considered to have failed.

[0095] Optionally, the method further includes at least one of the following:

[0096] The time for performing GNSS measurements is within the inactive period of the connected mode discontinuous reception (C-DRX) of the terminal (the specific time can be determined by the terminal).

[0097] The start time for performing GNSS measurements is the time when the first time information is received.

[0098] In this embodiment of the application, when the terminal completes GNSS measurement, it can trigger the reporting of the remaining valid duration of GNSS.

[0099] In some embodiments, the first condition includes the terminal receiving a first indication sent by the network-side device; that is, once the terminal receives the first indication, it considers the GNSS measurement function to be activated. However, when the first condition includes the terminal receiving a first indication sent by the network-side device, determining the timing information for the terminal to perform GNSS measurements is a problem that needs to be solved.

[0100] Optionally, in this embodiment of the application, if the first condition includes the terminal receiving a first indication sent by the network-side device, the method further includes:

[0101] If the terminal does not receive the first time information sent by the network-side device, the terminal obtains the second time information, which is the time information when the terminal performs GNSS measurements.

[0102] Optionally, the terminal obtains the second time information through one of the following methods:

[0103] 1) The third time information is used as the second time information, and the third time information is agreed upon by the protocol; the agreed time is, for example, 31 seconds.

[0104] Optionally, in this embodiment of the application, the second time information includes time length information.

[0105] In this embodiment of the application, optionally, the time length information includes timer information, time interval information, time window information, or period information.

[0106] 2) The most recently reported fourth time information is used as the second time information, wherein the fourth time information is the time information required for the terminal to perform GNSS measurements;

[0107] Optionally, in this embodiment, the fourth time information is: the fourth time information reported by the terminal to the currently connected network or the most recently connected network. The most recently connected network can also be referred to as the network that was most recently connected previously.

[0108] 3) The fifth time information is used as the second time information, and the fifth time information is configured by the network-side device.

[0109] Optionally, in this embodiment of the application, the fifth time information is carried via an RRC message.

[0110] Optionally, in this embodiment of the application, when the first indication is carried through a first RRC message, the first RRC message also carries the fifth time information. The first RRC message may include at least one of the following: an RRC connection setup message, an RRC connection resume message, an RRC connection re-establishment message, or an RRC connection reconfiguration message. It is understood that if the first RRC message carries the first indication, the first RRC message must also carry the fifth time information; in other words, if the first indication is included in the first RRC message, the fifth time information must also be included in the first RRC message.

[0111] The method described in this application clarifies when the terminal activates the GNSS measurement function (i.e., when the terminal can perform GNSS measurements); and clarifies how the terminal obtains the duration of GNSS measurement execution when it believes that the GNSS measurement function is activated upon receiving the network-side GNSS measurement enable configuration. This allows the terminal to perform GNSS measurements upon receiving the network-side GNSS measurement enable configuration. It is worth noting that the exact time the terminal performs GNSS measurements is based on the terminal's implementation.

[0112] Optionally, in this embodiment of the application, when obtaining the second time information involves using the fifth time information as the second time information, the method further includes:

[0113] If the fifth time information configured by the network-side device is not received, the terminal performs at least one of the following operations:

[0114] It is assumed that the value of the second time information is 0;

[0115] GNSS measurements are not performed.

[0116] The cell currently hosted or connected is deemed to be prohibited from hosting or connecting;

[0117] Leaving the RRC connection state;

[0118] Enter the RRC idle state (RRC_Idle).

[0119] Optionally, in this embodiment of the application, the GNSS measurement method further includes: after the terminal leaves the RRC connected state or enters the RRC idle state, and the remaining valid time of GNSS positioning is less than or equal to a preset time threshold, not initiating at least one of the following operations: connection establishment, connection recovery, connection reconstruction, or handover. The preset time threshold can be agreed upon by a protocol or configured by the network side. That is, if the remaining valid time of GNSS positioning is less than or equal to the preset time threshold, it indicates that the remaining valid time of GNSS positioning is limited, and it may become invalid after the initial access, connection recovery, connection reconstruction, or handover operation is performed. In this case, there is no need to initiate the initial access, connection recovery, connection reconstruction, or handover operation.

[0120] Optionally, in this embodiment of the application, the GNSS measurement method further includes: the terminal performing GNSS measurement based on the second time information.

[0121] Optionally, the terminal performs GNSS measurements based on the time length information indicated by the second time information. That is, the terminal can perform GNSS measurements using the time length information. It is understood that the terminal can perform GNSS measurements within the time period indicated by the time length information. If the terminal completes the GNSS measurement within the time period indicated by the time length information, the terminal can trigger the process of reporting the effective duration of the GNSS. If the terminal does not complete the GNSS measurement within the time period indicated by the time length information, the GNSS measurement is considered to have failed.

[0122] Optionally, the start time of the GNSS measurement is within the period of inactivity of the discontinuous reception in the connected state of the terminal, and the specific time can be determined based on the terminal. In this embodiment, when the terminal completes the GNSS measurement, it can trigger the reporting of the remaining valid duration of the GNSS.

[0123] Optionally, in this embodiment of the application, the GNSS measurement method further includes: after the terminal acquires the second time information, upon receiving the first time information sent by the network-side device, the terminal performs GNSS measurement based on the first time information. That is, the network-side device can update the duration of the GNSS measurement performed by the terminal. Optionally, the first time information can be carried via a MAC CE.

[0124] Optionally, in this embodiment of the application, the GNSS measurement method further includes: the GNSS measurement includes at least one of the following:

[0125] Automatic GNSS surveying;

[0126] Network-triggered GNSS measurements.

[0127] The process of network-triggered GNSS measurement is as follows:

[0128] 1) During the initial access / connection recovery / connection reconstruction / switching process, the terminal reports GNSS-ValidityDuration (indicating the remaining valid duration of the terminal's GNSS positioning) and GNSS-PositionFixDuration (indicating the time required for the terminal to perform GNSS measurements) via Message5 (Msg5).

[0129] 2) The network side can trigger the terminal to perform GNSS measurements during the GNSS measurement gap by sending a MAC CE, wherein the value of the GNSS measurement gap is indicated by the MAC CE.

[0130] 3) After the terminal successfully performs GNSS measurement, it reports the remaining valid duration of the GNSS positioning via MAC CE.

[0131] The process of automatic GNSS measurement is as follows:

[0132] 1) The terminal can perform automatic GNSS measurements during the inactive state of the connected discontinuous reception (C-DRX) period, and the exact start time of the GNSS measurement is determined based on the implementation.

[0133] 2) After the terminal successfully performs GNSS measurement, it reports the remaining valid duration of the GNSS positioning via MAC CE.

[0134] It should be noted that the terminal in this application embodiment is a terminal with GNSS measurement capability, such as an NB-IoT user equipment (UE) or an eMTC UE.
