Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] Figure 1 It is a schematic diagram of an application scenario of an embodiment of the present application.

[0031] like Figure 1 As shown, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0032] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems.

[0033] exist Figure 1In the communication system 100 shown, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (eg, UE) located within the coverage area.

[0035] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.

[0036] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.

[0037] The terminal device 110 can be used for device-to-device (D2D) communication.

[0038] The wireless communication system 100 may further include a core network device 130 for communicating with the base station. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

[0039] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.

[0040] For example, the terminal device establishes an air interface connection with the access network device through the NR interface for transmitting user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (referred to as N1); the access network device, such as the next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (referred to as N3); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (referred to as N2); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (referred to as N4); the UPF can exchange user plane data with the data network through the NG interface 6 (referred to as N6); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (referred to as N11); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (referred to as N7).

Optionally, the wireless communication system 100 may include multiple base station devices and the coverage area of ​​each base station may include other numbers of terminal devices, which is not limited in the embodiments of the present application.

[0042] 3GPP is researching Non-Terrestrial Network (NTN) technology. NTN generally uses satellite communications to provide communications services to users on the ground. Compared to terrestrial cellular networks, satellite communications offer many unique advantages. First, satellite communications are not restricted by user location. For example, conventional terrestrial communications cannot cover areas such as oceans, high mountains, and deserts where communications equipment cannot be deployed or where there is a sparse population. However, satellite communications, because a single satellite can cover a large area and satellites orbit the Earth, theoretically every corner of the globe can be covered. Second, satellite communications have significant social value. Satellite communications can provide low-cost coverage in remote mountainous areas and poor, underdeveloped countries and regions, enabling people in these areas to enjoy advanced voice communications and mobile internet technologies, helping to narrow the digital divide with developed regions and promoting their development. Third, satellite communications offer long range, and the cost of communications does not increase significantly with increasing distance. Finally, satellite communications are highly stable and unaffected by natural disasters.

[0043] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with the NR system to form an NR-NTN system. Another example is that NTN technology can be combined with the Internet of Things (IoT) system to form an IoT-NTN system. IoT-NTN systems can include NB-IoT-NTN systems and eMTC-NTN systems.

[0044] Figure 2 This is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0045] like Figure 2 As shown, it includes a terminal device 1101 and a satellite 1102, and wireless communication can be performed between the terminal device 1101 and the satellite 1102. The network formed between the terminal device 1101 and the satellite 1102 can also be called NTN. Figure 2In the illustrated communication system architecture, satellite 1102 can function as a base station, enabling direct communication between terminal device 1101 and satellite 1102. In this system architecture, satellite 1102 can be referred to as a network device. In some embodiments of the present application, the communication system may include multiple network devices 1102, and each network device 1102 may include a different number of terminal devices within its coverage area, although this is not a limitation in the present embodiment.

[0046] Figure 3 This is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application.

[0047] like Figure 3 As shown, it includes terminal equipment 1201, satellite 1202 and base station 1203. Wireless communication can be carried out between terminal equipment 1201 and satellite 1202, and communication can be carried out between satellite 1202 and base station 1203. The network formed by terminal equipment 1201, satellite 1202 and base station 1203 can also be called NTN. Figure 3 In the architecture of the communication system shown, the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be transferred through the satellite 1202. In this system architecture, the base station 1203 can be called a network device. In some embodiments of the present application, the communication system may include multiple network devices 1203, and each network device 1203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application. The network device 1203 may be Figure 1 The network device 120 in.

[0048] It should be understood that the satellites 1102 or 1202 include but are not limited to:

[0049] Satellites in Low-Earth Orbit (LEO), Medium-Earth Orbit (MEO), Geostationary Earth Orbit (GEO), and High Elliptical Orbit (HEO) orbits, among others, can use multiple beams to cover the ground. For example, a single satellite can form dozens or even hundreds of beams to cover the ground. In other words, a single satellite beam can cover a ground area tens to hundreds of kilometers in diameter, ensuring satellite coverage and increasing the capacity of the entire satellite communication system.

[0050] For example, LEO satellites can have an altitude range of 500 km to 1500 km, with an orbital period of approximately 1.5 to 2 hours. The signal propagation delay for single-hop communication between users is generally less than 20 milliseconds, and the maximum satellite visibility time is 20 minutes. LEO satellites have short signal propagation distances and low link loss, requiring low transmit power from user terminals. GEO satellites can have an orbital altitude of 35,786 km and a period of 24 hours around the Earth. The signal propagation delay for single-hop communication between users is generally 250 milliseconds.

[0051] In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0052] It should be noted that Figures 1 to 3 The systems to which this application applies are merely illustrative examples. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" in this application simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this application generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit its specific implementation method. For example, predefined can refer to a definition in a protocol. It should also be understood that in the embodiments of the present application, the “protocol” can refer to a standard protocol in the field of communications, such as an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.

[0053] Satellites can be categorized as either transparent payload or regenerative payload based on their functionality. Transparent payload satellites only provide radio frequency filtering, frequency conversion, and amplification, transparently forwarding signals without altering the waveform of the signal being forwarded. Regenerative payload satellites, in addition to providing radio frequency filtering, frequency conversion, and amplification, can also offer demodulation / decoding, routing / conversion, and encoding / modulation, embodying some or all of the functions of a base station.

[0054] In the NTN, one or more gateways may be included for communication between satellites and terminals.

[0055] Figure 4 and Figure 5 Schematic diagrams of NTN scenarios based on transparent forwarding satellites and regenerative forwarding satellites are shown respectively.

[0056] like Figure 4 As shown in the figure, for the NTN scenario based on transparent forwarding satellite, the gateway and satellite communicate through the feeder link, and the satellite and terminal can communicate through the service link. Figure 5 As shown in the figure, for the NTN scenario based on regenerative forwarding satellites, satellites communicate with each other through interstar links, gateways and satellites communicate with each other through feeder links, and satellites and terminals can communicate with each other through service links.

[0057] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0058] In the NTN system, the terminal needs to use its own location information to perform timing advance (TA) adjustment, conditional switching, etc., which are described below.

[0059] TA adjustment: TA adjustment can also be understood as TA pre-compensation. The terminal calculates the propagation delay of the service link based on its own location information and the ephemeris information sent by the network side, that is, N TA,UE-specific The terminal uses the formula T according to the calculated propagation delay and other TA adjustment values ​​issued by the network. TA =(N TA +N TA,UE-specific +N TA,common +NTA,offset ) calculates the total timing advance and applies it to uplink transmission. TA It is the TA value indicated by the network side through the Random Access Response (RAR) or the timing advance command MAC CE, N TA,UE-specific is the TA value estimated by the terminal itself, N TA,offset It is determined based on the network frequency band and LTE or NR coexistence conditions or is predefined or indicated by the network equipment or set to 0, N TA,common It is determined based on timing information and / or timing change information.

[0060] Conditional switching: When the network configures the terminal's conditional switching as follows: the distance between the terminal and the reference point is greater than / less than a certain threshold and the reference signal receiving power (RSRP) is higher than / lower than a certain threshold, the terminal calculates the distance between the terminal and the reference point based on its own location information and the location information of the reference point sent by the network, and uses this distance and RSRP to trigger the conditional switching.

[0061] There are various ways for a terminal to obtain its own location information. Typically, a terminal can obtain its location information through its own Global Navigation Satellite System (GNSS) capabilities. However, this is not limited to this method and a terminal can also obtain its own location information through other methods such as 5G positioning. Furthermore, the terminal can determine the accuracy of the obtained location information (referred to as positioning accuracy) by calculating the received signal strength and the number of effective paths during the positioning process.

[0062] In an NTN system, the accuracy of a terminal's location information is highly correlated with system performance. For example, if a terminal transmits an uplink signal with a 60kHz subcarrier spacing (SCS) configuration, and the terminal's positioning error reaches 50m, the terminal will perform TA pre-compensation based on its acquired location information. This will cause the timing error of the uplink information reaching the base station to exceed the CP / 2 length, causing inter-symbol interference (ISI), affecting the transmission of other uplink signals within the system and degrading system performance. For another example, if the terminal's positioning error is large during conditional handover, the conditional handover may be triggered too early or too late, resulting in performance loss for the terminal's transmission.

[0063] Since the positioning accuracy of the terminal is affected by factors such as the terminal's positioning capability, the environment in which it is located, the positioning system, and the number of service satellites, the terminal cannot guarantee the accuracy of the position information it measures. TA,UE-specific The accuracy of the terminal's location information is transparent to the network. Inaccurate location information can have negative consequences, such as interference with the NTN system's uplink signal and terminal handover errors.

[0064] In order to solve the problem that inaccurate location information affects the system performance of uplink transmission, terminal switching behavior, etc., the following technical solutions of the embodiments of the present application are proposed. In the technical solution of the embodiments of the present application, the terminal records and reports the positioning accuracy information. The network side can clarify the accuracy of the terminal's positioning information through the positioning accuracy information, thereby assisting the network side in determining the reliability of the terminal's uplink transmission and switching behavior, and further assisting the network side in performing some optimizations, such as assisting the network side in uplink resource scheduling, changing the switching configuration, configuring a specific TA value, etc., thereby improving network performance.

[0065] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0066] It should be noted that the following technical solutions of the embodiments of the present application can be applied to, but are not limited to, NR-NTN systems and IoT-NTN systems.

[0067] It should be noted that the "positioning accuracy information" in the following technical solutions of the embodiments of this application is used to indicate the first accuracy or the second accuracy, where the first accuracy is higher than the second accuracy. The first accuracy can also be understood as high accuracy, and the second accuracy can also be understood as low accuracy. In some optional implementations, a positioning accuracy greater than or equal to the first positioning accuracy threshold can be referred to as high accuracy, and a positioning accuracy less than or equal to the second positioning accuracy threshold can be referred to as low accuracy. The first positioning accuracy threshold and the second positioning accuracy threshold can be equal or different.

[0168] It should be noted that the “positioning accuracy threshold” described in the embodiments of the present application can also be described as a “positioning distance error threshold”.

[0169] The technical solutions of the embodiments of the present application are illustrated below with reference to specific application examples.

[0170] Application Example 1

[0171] When the terminal is in idle or inactive state, it needs to perform TA pre-compensation when sending random access messages (such as PRACH, MSG1, MSGA, etc.) during the random access process. The terminal in the NTN system needs to calculate the propagation delay of the service link based on the location information obtained by its own positioning, that is, the UE-specific TA value (N TA,UE-specific If the terminal's location information obtained through positioning is inaccurate, the network may not be able to correctly receive the random access message. To optimize this issue, the network can configure the terminal to perform logged MDT. The terminal uses logged MDT to record and report positioning accuracy information, assisting the network in adjusting the transmission configuration related to the random access message.

[0172] 1) The network side performs positioning-related configuration on the terminal. Specifically, the network side performs at least one of the following configurations:

[0173] a) The network side configures the terminal to record and report at least one of the following information: the location information of the terminal positioning, the terminal positioning accuracy information (used to indicate high accuracy or low accuracy), the positioning system used by the terminal positioning, and the timestamp of the terminal positioning behavior.

[0174] b) The network side configures the terminal to determine the positioning accuracy criteria, wherein the positioning accuracy criteria include at least one of the following: a first positioning accuracy threshold corresponding to high accuracy, and a second positioning accuracy threshold corresponding to low accuracy.

[0175] c) Terminal recording duration: The maximum duration of valid recording before the terminal enters the connected state.

[0176] d) Number of terminal records: The maximum number of valid records before the terminal enters the connected state.

[0177] 2) The terminal records and reports at least one of the following information based on the configuration of the network side or the terminal's own choice: the location information of the terminal positioning, the terminal's positioning accuracy information (used to indicate high accuracy or low accuracy), the positioning system used by the terminal, and the timestamp of the terminal positioning behavior.

[0178] 3) The network side can make at least one of the following adjustments based on the information reported by the terminal:

[0179] a) The network prohibits terminals in specific locations from accessing.

[0180] Specifically, the network issues a prohibition signaling and a geographic location area, thereby prohibiting access by terminals in a specific location. Optionally, the geographic location area can be determined by N location coordinates (N is a positive integer), or by one location coordinate and a radius distance.

[0181] b) The network extends the time window for receiving the preamble for the terminal at a specific location.

[0182] c) The network broadcasts a geographic location area and the area TA value (TA-area) corresponding to the geographic location area. Optionally, the TA margin may also be broadcast.

[0183] 4) If the terminal receives the geographic location area broadcast by the network side and the TA-area corresponding to the geographic location area, the terminal (optionally, it can judge the current positioning accuracy according to the positioning accuracy judgment criteria issued by the network side); if the current positioning accuracy is low, the terminal uses TA-area instead of TA-UE-specific (i.e., UE-specific TA value: N TA,UE-specific ) for uplink transmission.

[0184] 5) If the terminal receives the access prohibition signaling and a geographic location area broadcast by the network side, the terminal determines the current positioning accuracy (optionally, according to the positioning accuracy judgment criteria issued by the network side); if the current positioning accuracy is low, the terminal exits the random access process.

[0185] In the technical solution of the embodiments of this application, a terminal in a non-connected state (i.e., idle or inactive) notifies the network of its positioning accuracy via loggedMDT reporting. Positioning-related information from a large number of terminals is used to assist the network in determining the status of the terminal's positioning module and the terminal's positioning capabilities in conjunction with its geographic location. This further assists the network in adjusting the terminal's uplink resource configuration and optimizing the network.

[0186] Application Example 2

[0187] When the terminal is in the connected state, TA pre-compensation is required when the terminal sends the uplink signal. The terminal in the NTN system needs to calculate the propagation delay of the service link based on the location information obtained by its own positioning, that is, the UE-specific TA value (N TA,UE-specific If the terminal's location information obtained through positioning is inaccurate, the network may not be able to correctly receive uplink signals. This can even cause intersymbol interference (ISI) with other uplink signals, affecting the reception of other uplink signals and reducing overall system throughput. To address this issue, the network can configure immediate MDT. Terminals use this technology to record and report positioning accuracy information, assisting the network in adjusting resource allocation and other factors.

[0188] 1) The network side performs positioning-related configuration on the terminal. Specifically, the network side performs at least one of the following configurations:

[0189] a) The network side configures the terminal to record and report at least one of the following information: the terminal's positioning accuracy information (used to indicate high accuracy or low accuracy), the positioning system used by the terminal for positioning, and the timestamp of the terminal's positioning behavior.

[0190] b) The network side configures the terminal to determine the positioning accuracy criteria, wherein the positioning accuracy criteria include at least one of the following: a first positioning accuracy threshold corresponding to high accuracy, and a second positioning accuracy threshold corresponding to low accuracy.

[0191] c) Configure the terminal report on the network as follows:

[0193] ii: Event-triggered reporting; specifically, the network side configures reporting when the terminal positioning accuracy is low; and / or reporting when the terminal positioning accuracy is high.

[0194] 2) The terminal records and reports at least one of the following information according to the configuration on the network side or the terminal itself: the location information of the terminal positioning, the positioning accuracy information of the terminal (used to indicate high accuracy or low accuracy), the positioning system used by the terminal, and the timestamp of the terminal positioning behavior.

[0195] 3) The network side can make at least one of the following adjustments based on the information reported by the terminal:

[0196] a) The terminal is prohibited from accessing the network.

[0197] b) The network configures dedicated uplink resources for the terminal.

[0198] c) The network adjusts the conditional configuration of the conditional switching of the terminal.

[0199] d) The network adjusts the conditional configuration of terminal condition switching in a specific location.

[0200] Specifically, the network sends a conditional switching configuration and a geographic location area, thereby adjusting the conditional configuration of the terminal conditional switching in a specific location. Here, optionally, the geographic location area can be determined by N location coordinates (N is a positive integer), or it can also be determined by a location coordinate and a radius distance.

[0201] e) The network prohibits terminals in specific locations from accessing.

[0202] Specifically, the network issues a prohibition signaling and a geographic location area, thereby prohibiting access by terminals in a specific location. Optionally, the geographic location area can be determined by N location coordinates (N is a positive integer), or by one location coordinate and a radius distance.

[0203] f) The network configures dedicated uplink resources for terminals in specific locations.

[0204] g) The network broadcasts or unicasts a geographic location area and the TA-area corresponding to the geographic location area. Optionally, the TAmargin may also be broadcast or unicast.

[0205] h) The network sends a location suggestion to the terminal, such as direction and distance.

[0206] 4) If the terminal receives the geographic location area broadcast or unicast by the network side, and the TA-area corresponding to the geographic location area, the terminal (optionally, it can judge the current positioning accuracy according to the positioning accuracy judgment criteria issued by the network side); if the current positioning accuracy is low, the terminal uses TA-area instead of TA-UE-specific (i.e., UE-specific TA value: N TA,UE-specific ) for uplink transmission.

[0207] 5) If the terminal receives the access prohibition signaling and a geographic location area broadcast by the network side, the terminal determines the current positioning accuracy (optionally, according to the positioning accuracy judgment criteria issued by the network side); if the current positioning accuracy is low, the terminal exits the random access process.

[0208] 6) If the terminal receives the conditional switching configuration and a geographical location area sent by the network side, the terminal determines whether it is in the geographical location area. If so, the terminal applies the conditional switching configuration sent by the network side.

[0209] In the technical solution of the embodiments of this application, the terminal connection status informs the network side of the terminal's positioning accuracy information through MDT, RRC reporting, and other methods. Positioning-related information from a large number of terminals is used to assist the network side in determining the status of the terminal's positioning module and the terminal's positioning capabilities combined with its geographic location. This further assists the network side in adjusting the terminal's uplink resource configuration and assisting in network optimization.

[0210] Application Example 3

[0211] The base station receives the uplink signal and at a certain moment a demodulation failure occurs, and detects that there is inter-symbol interference between the uplink signals from terminal 1 to terminal N.

[0212] The base station sends at least one of the following configurations to terminals 1 to N:

[0213] 1) Configure the terminal to report positioning accuracy information;

[0214] 2) Configure the terminal's criteria for determining positioning accuracy. Specifically, configure a positioning accuracy threshold corresponding to high accuracy.

[0215] 3) Configure event-triggered reporting. Specifically, configure the reporting condition to report when the terminal is in high accuracy.

[0216] Each terminal from terminal 1 to terminal N measures the latest positioning accuracy according to the configuration sent by the base station, and reports its positioning accuracy information to the base station for the terminal with the latest positioning accuracy being high.

[0217] The base station monitors the reports from terminal 1 to terminal N, finds the terminal that has not reported, and adjusts the resource allocation of the terminal.

[0218] Application Example 4

[0219] The base station configures the terminal in the non-connected state to record and report. Specifically, the base station sends at least one of the following configurations:

[0220] 1) Configure the terminal to record and report the following information: terminal positioning location information, terminal positioning accuracy information, and the timestamp of the terminal positioning behavior.

[0221] 2) Configuring the terminal to determine the positioning accuracy criteria, wherein the positioning accuracy criteria include at least one of the following: a first positioning accuracy threshold corresponding to high accuracy, and a second positioning accuracy threshold corresponding to low accuracy.

[0222] 3) Configure the terminal recording duration: the maximum duration T1 of valid recording before the terminal enters the connected state.

[0223] The terminal reports at least one of the following information according to the configuration sent by the base station: location information of the terminal, positioning accuracy information of the terminal, and timestamp of the terminal positioning behavior.

[0224] The base station / network receives the information recorded and reported by the terminal and performs data analysis. By analyzing the massive amount of data, it is possible to find the geographical location area where the current / recent positioning signal (such as GNSS signal) is unreliable, and adjust the terminal behavior in the geographical location area. As an example, Figure 8 As shown, one way to implement data analysis on the network is as follows: the network can find coverage holes (i.e. Figure 8 The network makes at least one of the following adjustments for unreliable geographic locations:

[0225] 1) The network broadcasts a geographic location area and the TA-area corresponding to the geographic location area. Optionally, it can also broadcast TAmargin.

[0226] For example, the network broadcasts a location center point and a radius (typically with redundancy) around the center point. This center point and radius determine a circular geographic location area. Terminals within this geographic location area use the TA-area. Specifically, when a non-connected terminal initially accesses, it determines whether it is within the geographic location area. If so, the terminal uses the TA-area issued by the network instead of the TA-UE-specific for uplink transmission.

[0227] The technical solution of the embodiments of the present application designs a method for terminals in an NTN system to report the accuracy of their measured location information (i.e., positioning accuracy) to assist the network in network optimization. The network can configure / trigger terminals to report their positioning accuracy, or terminals can autonomously record and report their positioning accuracy. Terminals reporting positioning accuracy assists the network in determining whether terminals are using low-accuracy location information, resulting in degraded system performance. Based on the information reported by the terminals, the network can perform actions such as resource reallocation or access denial for low-accuracy terminals to optimize the network.
