[0057] The following is a brief introduction to some of the technical contents 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 encompasses any network involving non-terrestrial aircraft, including satellite communication networks and high-altitude platform systems (HAPs). NTN enables traditional 3GPP terrestrial networks to transcend the limitations of the Earth's surface and expand into natural spaces such as air, sea, and land. Because 3GPP's current focus has been on satellite communication networks, the narrow definition of NTN primarily refers to satellite communications.

[0060] (2) Connected GNSS measurement

[0061] In NTN scenarios, terminals need to perform GNSS measurements to obtain GNSS positioning. In Release 17 of the Internet of Things NTN (IoT-NTN), simultaneous GNSS measurements and narrowband IoT (NB-IoT) / enhancement machine type communication (eMTC) data transmission operations are not supported. Terminals can only perform GNSS measurements in the RRC idle state (RRC_IDLE). If the terminal's GNSS positioning is outdated, the terminal must switch to the RRC idle state to perform GNSS measurements. To enable terminals in the RRC connected state to perform GNSS measurements, Release 18 of the IoT-NTN introduces two mechanisms: network-triggered GNSS measurement and automatic GNSS measurement.

[0062] FIG1 shows a block diagram of a wireless communication system applicable to embodiments of the present 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 the data network. It should be noted that the number of communication devices in the wireless communication system shown in FIG1 is only used as an example. The number of communication devices may also be multiple, and the connection relationship may also be changed according to actual conditions. The example in FIG1 does not limit the wireless communication system provided in embodiments of the present application. For example, FIG1 shows only one terminal 11. In some embodiments, the wireless communication system shown in FIG1 may have more terminals 11 and communicate with the satellite 12.

[0063] The terminal 11 may be a mobile phone, tablet computer, laptop computer, notebook 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), shipborne equipment, pedestrian user equipment (PUE), smart home (home appliances with wireless communication functions, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM or self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. The vehicle-mounted device may also be referred to as a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip, or a vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0064] The following, in conjunction with the accompanying drawings, describes in detail the GNSS measurement method, terminal, network-side device, and readable storage medium provided in the embodiments of the present application through some embodiments and their application scenarios.

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

[0066] Referring to FIG. 2 , an embodiment of the present application provides a GNSS measurement method, including:

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

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

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

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

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

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

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

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

[0075] In the embodiment of the present application, optionally, the terminal is in an RRC connected state and, if the first condition is met, the terminal performs GNSS measurement. That is, the terminal may be a terminal in an RRC connected state, and the terminal has the ability to perform GNSS measurement in the connected state. The GNSS measurement in the embodiment of the present application may be a GNSS measurement performed by the terminal in the RRC connected state.

[0076] In the example of the present application, optionally, the network side device may be a network side device in an NTN network, for example, a satellite, a drone or an airplane, or a ground base station connected to a satellite.

[0077] In an embodiment of the present application, the first indication may be gnss-AutonomousEnabled.

[0078] Optionally, the first indication may be carried by 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 Reestablishment message, or an RRC Connection Reconfiguration message.

[0079] In an embodiment of the present application, optionally, the first time information is time information configured by a network-side device for the terminal to perform GNSS measurement based on the time required for GNSS measurement reported by the terminal. Optionally, the first time information includes time length information, and 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 requirement for the terminal to perform GNSS measurement. In an embodiment of the present application, optionally, the terminal performing GNSS measurement can also be described as the GNSS measurement function being activated.

[0080] In the embodiment of the present application, optionally, the terminal not performing GNSS measurement can also be described as the GNSS measurement function not being activated. It is understandable that the terminal not performing GNSS measurement includes not performing any one of automatic GNSS measurement and network-triggered GNSS measurement, or not performing automatic GNSS measurement and not performing network-triggered GNSS measurement.

[0081] In the embodiments of the present application, it is clarified when the terminal can perform GNSS measurement, or when to activate the GNSS measurement function, so that the terminal can perform GNSS measurement in a timely manner and avoid communication failures caused by outdated GNSS positioning.

[0082] In the embodiment of the present application, optionally, the first time information is carried by 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 Resume message, an RRC Connection Reestablishment message, or an RRC Connection Reconfiguration message.

[0083] In an embodiment of the present application, optionally, the first time information includes time length information, that is, the terminal can perform GNSS measurement within the time length.

[0084] In an embodiment of the present application, optionally, the first time information is timer information, time interval (gap) information, time window (Windows) information, or period (period) information. When the first time information includes timer information, the timer information may include a timer length. The timer is started when the terminal performs a GNSS measurement. If the timer does not time out and the terminal completes the GNSS measurement, the timer is stopped. If the timer times out but the terminal does not complete the GNSS measurement, the GNSS measurement is considered to have failed.

[0085] In an embodiment of the present application, optionally, when the first condition includes the terminal receiving a first indication and first time information sent by a network-side device, the method further includes: when the terminal receives the first indication 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 enablement of GNSS measurement is not applicable. That is, in the embodiment of the present application, upon receiving only the first indication, the terminal does not activate the GNSS measurement function, but waits until the first time information is received before activating the GNSS measurement function.

[0086] Therefore, when the terminal can perform GNSS measurement, the embodiment of the present application provides a specific solution for the terminal to obtain time information and perform GNSS measurement based on the time information.

[0087] The process of performing GNSS measurements on a terminal is as follows: the terminal receives signals transmitted by satellites at precise intervals. The satellite's position can be found in the satellite's ephemeris. The distance from the terminal to the satellite is calculated by multiplying the time it takes for the signal to travel from the satellite to the user by the speed of light. Combining data from multiple satellites yields the terminal's position, known as the GNSS position. Due to the mobility of both the terminal and satellites, GNSS positioning typically has a validity period; after this period, the GNSS position is considered invalid or outdated.

[0088] In the embodiment of the present application, optionally, 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] Leave the RRC connected state;

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

[0091] In the embodiment of the present application, the GNSS positioning is outdated, which can also be described as the GNSS positioning is invalid.

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

[0093] In an embodiment of the present application, optionally, when the first condition includes the terminal receiving a first indication and first time information sent by a network-side device, the method further includes: the terminal performing GNSS measurement based on the first time information.

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

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

[0096] The time for performing the GNSS measurement is within a period of inactivity of a connected mode discontinuous reception (C-DRX) of the terminal (the specific time may be determined by the terminal implementation);

[0097] The start time of executing the GNSS measurement is the time when the first time information is received.

[0098] In the embodiment of the present application, when the terminal completes the GNSS measurement, it can trigger the reporting of the remaining effective time of the GNSS.

[0099] In some embodiments, the first condition includes the terminal receiving a first indication sent by a network-side device, i.e., upon receiving the first indication, the terminal deems the GNSS measurement function to be activated. However, when the first condition includes the terminal receiving the first indication sent by the network-side device, determining the time information at which the terminal performs the GNSS measurement is a problem that needs to be solved.

[0100] In the embodiment of the present application, optionally, when the first condition includes that the terminal receives a first indication sent by a network-side device, the method further includes:

[0101] In a case where the first time information sent by the network-side device is not received, the terminal acquires second time information, where the second time information is time information for the terminal to perform GNSS measurement.

[0102] Optionally, the terminal obtains the second time information in one of the following ways:

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

[0104] In an embodiment of the present application, optionally, the second time information includes time length information.

[0105] In an embodiment of the present application, optionally, the time length information includes timer information, time interval information, time window information or cycle information.

[0106] 2) using the most recently reported fourth time information as the second time information, where the fourth time information is the time information required for the terminal to perform GNSS measurement;

[0107] In the embodiment of the present application, optionally, 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 may also be referred to as the most recently connected network.

[0108] 3) Using fifth time information as the second time information, wherein the fifth time information is configured by the network side device.

[0109] In an embodiment of the present application, optionally, the fifth time information is carried through an RRC message.

[0110] In an embodiment of the present application, optionally, when the first indication is carried by 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 establishment (RRCConnectionSetup) message, an RRC connection recovery (RRCConnectionResume) message, an RRC connection reconstruction (RRCConnectionReestablishment) message, and an RRC connection reconfiguration (RRCConnectionReconfiguration) message. It can be understood that when the first RRC message carries the first indication, the first RRC message must carry the fifth time information. In other words, if the first indication is included in the first RRC message, the fifth time information must be included in the first RRC message.

[0111] The method of the embodiment of the present application clarifies when the terminal activates the GNSS measurement function (i.e., the terminal can perform GNSS measurements). Furthermore, when the terminal believes that the GNSS measurement function is activated upon receipt of a network-side configuration enabling GNSS measurement, it clarifies how the terminal obtains the length of time to perform GNSS measurements. This allows the terminal to perform GNSS measurements upon receipt of a network-side configuration enabling GNSS measurement. It is worth noting that the exact time at which the terminal performs GNSS measurements is based on the terminal's implementation.

[0112] In the embodiment of the present application, optionally, when obtaining the second time information is to use the fifth time information as the second time information, the method further includes:

[0113] In a case where 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 considered that the value of the second time information is 0;

[0115] No GNSS measurements are performed;

[0116] It is considered that the cell currently camped on or connected to is prohibited from camping on or connecting to;

[0117] Leave the RRC connected state;

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

[0119] In an embodiment of the present application, optionally, the GNSS measurement method further includes: after the terminal leaves the RRC connected state or enters the RRC idle state, and when the remaining effective time of the GNSS positioning is less than or equal to the preset time threshold, at least one of the operations of connection establishment, connection recovery, connection reconstruction, and switching is not initiated. The preset time threshold may be agreed upon by the protocol or configured by the network side. That is to say, if the remaining effective time of the GNSS positioning is less than or equal to the preset time threshold, it means that the remaining effective time of the GNSS positioning is not much, and it is possible that the initial access or connection recovery or connection reconstruction or switching operation will fail. At this time, there is no need to initiate the initial access or connection recovery or connection reconstruction or switching operation.

[0120] In the embodiment of the present application, optionally, the GNSS measurement method further includes: the terminal performing GNSS measurement based on the second time information.

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

[0122] Optionally, the start time of executing GNSS measurement is within the period of the inactive state of discontinuous reception in the connected state of the terminal, and the specific time can be determined based on the terminal implementation. In the embodiment of the present application, when the terminal completes the GNSS measurement, it can trigger reporting of the remaining effective time of GNSS.

[0123] In an embodiment of the present application, optionally, 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. In other words, the network-side device may update the length of time the terminal performs GNSS measurement. Optionally, the first time information may be carried in a MAC CE.

[0124] In an embodiment of the present application, optionally, the GNSS measurement method further includes: the GNSS measurement includes at least one of the following:

[0125] Automatic GNSS measurement;

[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 re-establishment / handover process, the terminal reports GNSS-ValidityDuration (used to indicate the remaining valid duration of the terminal's GNSS positioning) and GNSS-PositionFixDuration (used to indicate the time required for the terminal to perform GNSS measurement) through Message 5 (Msg5).

[0129] 2) The network side may trigger the terminal to perform GNSS measurement during a 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 effective time of the terminal's GNSS positioning through MAC CE.

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

[0132] 1) The terminal may perform automatic GNSS measurements during the inactive state of C-DRX in connected state. The exact start time of the GNSS measurements is determined by the implementation.

[0133] 2) After the terminal successfully performs GNSS measurement, it reports the remaining effective time of the terminal's GNSS positioning through MAC CE.

[0134] It should be noted that the terminal in the embodiment of the present application is a terminal with GNSS measurement capability, for example, it can be an NB-IoT user equipment (UE) or an eMTC UE.

[0135] Referring to FIG3 , an embodiment of the present application further provides a GNSS measurement method, including:

[0136] Step 31: The network-side device sends at least one of a first indication and first time information to the terminal;

[0137] The first indication is used to instruct the network-side device to enable GNSS measurement of the terminal, and the first time information is time information of the terminal performing GNSS measurement;

[0138] Among them, receiving the first indication is the first condition for the terminal to perform GNSS measurement, or receiving the first indication and first time information is the first condition for the terminal to perform GNSS measurement, or receiving the first time information is the first condition for the terminal to perform GNSS measurement.

[0139] In an embodiment of the present application, optionally, the first time information is time information for the terminal to perform GNSS measurement, which is configured for the terminal by the network side device based on the time required for the GNSS measurement reported by the terminal.
