Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.
[0052] The terms "first", "second", etc. of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of one type, and the number of objects is not limited, for example, the first object can be one or more.

The character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0053] The term "indication" in this application can be a direct indication (or explicit indication) or an indirect indication (or implicit indication). A direct indication can be understood as the sender explicitly informing the receiver of specific information, operations to be performed, or request results in the sent indication; an indirect indication can be understood as the receiver determining the corresponding information according to the indication sent by the sender, or making a judgment and determining the operation to be performed or the request result according to the judgment result.
[0054] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA) or other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the above-mentioned systems and radio technologies as well as other systems and radio technologies. The following description describes a new radio (NR) system for example purposes, and NR terms are used in most of the following descriptions, but these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.
[0055] The following is a brief introduction to some technical contents involved in this application.
[0056] (1) Non-Terrestrial Network (NTN)
[0057] The standard definition given by 3GPP for NTN is "a network or network segment that uses airborne or space vehicles to carry transmission equipment relay nodes or base stations." In short, it is a general term for any network involving non-ground flying objects, including satellite communication networks and high altitude platform systems (HAPs). NTN enables traditional 3GPP ground networks to break through the limitations of the surface and expand to natural spaces such as air, sea, and land. Since the current focus of 3GPP work has always been on satellite communication networks, the narrow sense of NTN mainly refers to satellite communications.
[0058] (2) Connected GNSS measurement
[0059] In the NTN scenario, the terminal needs to perform GNSS measurement to obtain GNSS positioning. In R17 IoT-NTN, simultaneous GNSS measurement and Narrow Band Internet of Things (NB-IoT) / enhancement machine type of communication (eMTC) data transmission operations are not supported. The terminal can only perform GNSS measurement in the RRC idle state (RRC_IDLE). If the terminal GNSS positioning is outdated, the terminal must go to the RRC idle state to perform GNSS measurement operations. In order to allow the terminal in the RRC connected state to perform GNSS measurement, R18 IoT-NTN introduces two mechanisms: network-triggered GNSS measurement and automatic GNSS measurement.
[0060] Figure 1 The block diagram of a wireless communication system applicable to the embodiment of the present application is shown. 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 Figure 1 The number of communication devices in the wireless communication system shown is only used as an example. The number of communication devices may be multiple, and the connection relationship may also be changed according to actual conditions. Figure 1 The example is not intended to limit the wireless communication system provided in the embodiments of the present application. For example, Figure 1 Only one terminal 11 is shown in FIG. 1 . In some embodiments, Figure 1 More terminals 11 may exist in the wireless communication system shown and communicate with the satellite 12 .
[0061] Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device (Wearable Device), a flight vehicle, a vehicle user equipment (VUE), a shipborne equipment, a pedestrian terminal (Pedestrian User Equipment, PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, televisions, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine and other terminal side devices.

[0062] The GNSS measurement method, terminal, network-side device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.
[0063] 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, air-space integration scenarios, etc.
[0064] Please refer to Figure 2 , an embodiment of the present application provides a GNSS measurement method, comprising:
[0065] Step 21: When the first condition is met, the terminal performs GNSS measurement;
[0066] The first condition includes any one of the following:
[0067] The terminal receives a first instruction and first time information sent by a network side device;
[0068] The terminal receives a first instruction sent by a network side device;
[0069] The terminal receives first time information sent by the network side device;
[0070] 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 for the terminal to perform GNSS measurement.
[0071] In the embodiment of the present application, GNSS measurement may also be referred to as GNSS acquisition or GNSS re-acquisition, that is, acquisition or re-acquisition of GNSS positioning.
[0072] The terminal performing GNSS measurement may also be understood as the terminal being enabled to perform GNSS measurement.
[0073] In the embodiment of the present application, optionally, the terminal is in an RRC connected state, and when 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.
[0074] 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.
[0075] In this embodiment of the present application, the first indication may be gnss-AutonomousEnabled.
[0076] 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 establishment (RRCConnectionSetup) message, an RRC connection recovery (RRCConnectionResume) message, an RRC connection reconstruction (RRCConnectionReestablishment) message, and an RRC connection reconfiguration (RRCConnectionReconfiguration) message.
[0077] In an embodiment of the present application, optionally, the first time information is time information for the terminal to perform GNSS measurement configured by the network side device based on the time required for the 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 the GNSS measurement reported by the terminal 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.
[0078] In the embodiment of the present application, optionally, the terminal does not perform GNSS measurement, which can also be described as the GNSS measurement function is not activated. It can be understood that the terminal does not perform GNSS measurement, including not performing any one of automatic GNSS measurement and network-triggered GNSS measurement, not performing automatic GNSS measurement, and not performing network-triggered GNSS measurement.
[0079] 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 time and avoid communication failures caused by outdated GNSS positioning.
[0080] 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 (GNSS Measurement Command MAC CE). The 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.
[0081] 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.
[0082] In the 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 the length of the timer, which is started when the terminal performs GNSS measurement, and 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, it is considered that the GNSS measurement has failed.
[0083] In the embodiment of the present application, optionally, in the case where the first condition includes that the terminal receives the first indication and the first time information sent by the network side device, the method further includes: in the case where the first indication sent by the network side device is received but the first time information sent by the network side device is not received, 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 to say, in the embodiment of the present application, the terminal does not activate the GNSS measurement function after only receiving the first indication, but waits until the first time information is received before activating the GNSS measurement function.
[0084] Therefore, in the case where 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.
[0085] The process of terminal performing GNSS measurement is as follows: the terminal receives the signal transmitted by the satellite to the ground at precise time intervals. The position of the satellite 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 transmitted by the satellite to propagate to the user by the speed of light. The position of the terminal can be obtained by integrating the data of multiple satellites, that is, GNSS positioning. Due to the mobility of the terminal and the satellite, GNSS positioning usually has a valid time. If the valid time is exceeded, the GNSS positioning is considered invalid or outdated.
[0086] 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:
[0087] Leave the RRC connected state;
[0088] Enter the RRC idle state (RRC_IDLE).
[0089] In the embodiment of the present application, the GNSS positioning is outdated can also be described as the GNSS positioning is invalid.
[0090] 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.
[0091] In an embodiment of the present application, optionally, when the first condition includes that the terminal receives a first indication and first time information sent by a network side device, the method further includes: the terminal performs GNSS measurement based on the first time information.
[0092] Optionally, the terminal performs GNSS measurement based on the time length information indicated by the first time information. That is, the terminal can perform GNSS measurement using the time length information. It can be understood that the terminal can 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 can trigger a process of reporting the GNSS effective duration. If the terminal does not complete the GNSS measurement within the time indicated by the time length information, it is considered that the GNSS measurement has failed.
[0093] Optionally, the method further comprises at least one of the following:
[0094] The time for performing the GNSS measurement is within a period of time when the C-DRX (discontinuous reception in connected state) of the terminal is in an inactive state (the specific time may be determined by the terminal implementation);
[0095] The start time of executing the GNSS measurement is the time when the first time information is received.
[0096] In the embodiment of the present application, when the terminal completes the GNSS measurement, it can trigger reporting of the remaining effective time of the GNSS.
[0097] In some embodiments, the first condition includes the terminal receiving a first indication sent by a network side device, that is, once the terminal receives the first indication, the GNSS measurement function is considered to be activated. However, in the case where the first condition includes the terminal receiving the first indication sent by the network side device, how to determine the time information of the terminal performing the GNSS measurement is a problem that needs to be solved.
[0098] 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:
[0099] In the 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 the time information for the terminal to perform GNSS measurement.
[0100] Optionally, the terminal obtains the second time information in one of the following ways:
[0101] 1) Using the third time information as the second time information, the third time information is agreed upon by a protocol; the time agreed upon by the protocol is, for example, 31 seconds.
[0102] In an embodiment of the present application, optionally, the second time information includes time length information.
[0103] In an embodiment of the present application, optionally, the time length information includes timer information, time interval information, time window information or cycle information.
[0104] 2) using the fourth time information reported most recently as the second time information, where the fourth time information is the time information required for the terminal to perform GNSS measurement;
[0105] 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.
[0106] 3) Using fifth time information as the second time information, wherein the fifth time information is configured by a network side device.
[0107] In an embodiment of the present application, optionally, the fifth time information is carried via an RRC message.
[0108] In an embodiment of the present application, optionally, in the case where 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, in the case where 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.
[0109] Through the method of the embodiment of the present application, it is clarified when the terminal activates the GNSS measurement function (that is, the terminal can perform GNSS measurement); when the terminal believes that the GNSS measurement function is activated when the network side enables the GNSS measurement configuration, it is clarified how the terminal obtains the time length for performing the GNSS measurement. The terminal can perform the GNSS measurement when the network side enables the GNSS measurement configuration. It is worth noting that the exact time when the terminal performs the GNSS measurement is based on the terminal implementation.
[0110] 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:
[0111] In the 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:
[0112] It is considered that the value of the second time information is 0;
[0113] No GNSS measurements are performed;
[0114] It is considered that the cell currently camped or connected is prohibited from camping or connecting;
[0115] Leave the RRC connected state;
[0116] Enter the RRC idle state (RRC_Idle).
[0117] 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 the remaining effective time of the GNSS positioning is less than or equal to a 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. In other words, if the remaining effective time of the GNSS positioning is less than or equal to the preset time threshold, it means that there is not much time left for the remaining effective time of the GNSS positioning, 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.
[0118] 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.
[0119] Optionally, the terminal performs GNSS measurement based on the time length information indicated by the second time information. That is, the terminal can perform GNSS measurement using the time length information. It can be understood that the terminal can 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 can 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, it is considered that the GNSS measurement has failed.
[0120] 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.
[0121] In the 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. That is, the network side device can update the time length for the terminal to perform GNSS measurement. Optionally, the first time information can be carried by MAC CE.
[0122] In the embodiment of the present application, optionally, the GNSS measurement method further includes: the GNSS measurement includes at least one of the following:
[0123] Automatic GNSS measurement;
[0124] Network triggered GNSS measurements.
[0125] The process of network-triggered GNSS measurement is as follows:
[0126] 1) During the initial access / connection recovery / connection reestablishment / switching 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 Msg5.
[0127] 2) The network side can trigger the terminal to perform GNSS measurement during the GNSS measurement gap by sending a MAC CE, where the value of the GNSS measurement gap is indicated by the MAC CE.
[0128] 3) After the terminal successfully performs GNSS measurement, the remaining effective time of the terminal's GNSS positioning is reported through MAC CE.
[0129] The process of automatic GNSS measurement is as follows:
[0130] 1) The terminal may perform automatic GNSS measurement during the period of the inactive state of the discontinuous reception (C-DRX) in the connected state. The exact start time of the GNSS measurement is determined based on the implementation.
[0131] 2) After the terminal successfully performs GNSS measurement, the remaining effective time of the terminal's GNSS positioning is reported through MAC CE.
[0132] It should be noted that the terminal in the embodiment of the present application is a terminal with GNSS measurement capability, for example, it may be a NB-IoT UE or an eMTC UE.
[0133] Please refer to Figure 3 , the embodiment of the present application also provides a GNSS measurement method, including:
