[0118] In some embodiments, NTN technology can be as shown in Figure 1B, where the gateway communicates with the satellite via a feeder link, and the satellite communicates with the terminal via a service link.

[0119] Based on the different ways satellites process signals, they can be divided into pass-through mode and regeneration mode.

[0120] In one example, the pass-through mode can be as shown in Figure 1C, where the NTN ground station sends the signal of the TN network device, such as the base station gNB, to the satellite. The satellite converts the signal to the satellite frequency band and then transmits it to the terminal through the satellite frequency band. Apart from frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, similar to a repeater.

[0121] In one example, the regeneration mode can be as shown in Figure 1D. After the NTN ground station sends the gNB signal to the satellite, the satellite first demodulates and decodes the signal and then re-encodes and modulates it (this process is called regeneration) and sends the regenerated signal through the satellite frequency band.

[0122] In a TN network, terminals can perform Radio Resource Management (RRM) measurements on neighboring cells using the Synchronization Signal Block Measurement Timing Configuration (SMTC) information configured by the network equipment. SMTC primarily configures the measurement time window so that the terminal can detect the reference signal of the neighboring cell within that window. For RRM measurements in the idle or inactive state, SMTC can be broadcast via system messages. For RRM measurements in the connected state, SMTC can be configured via dedicated Radio Resource Control (RRC) signaling.

[0123] In NTN networks, the increased propagation delay caused by the high-speed motion of low-Earth orbit (LEO) satellites poses a challenge to the use of SMTC on the terminal side. Specifically, the high-speed motion of LEO satellites results in significant and rapidly changing propagation delays between the terminal and the NTN serving cell, as well as between the terminal and neighboring NTN cells. SMTC needs to be adjusted accordingly to adapt to the propagation delays of the reference signals from the serving cell and neighboring cells.

[0124] In some embodiments, SMTC adjustments in an NTN network may include, but are not limited to, the following two:

[0125] In IDLE or INACTIVE state, the terminal adjusts SMTC based on its own location information and auxiliary information broadcast in system messages such as System Information Blocks 19 (SIB19). Auxiliary information may include ephemeris information, common timing advance (TA) parameters, and an offset k configured to accommodate larger round-trip times.mac Parameters, etc.

[0126] In CONNECTED state, the terminal can report the Propagation Delay Difference (PDD) auxiliary information between the serving cell and neighboring cells to the network device. The network device adjusts the SMTC configuration based on the PDD auxiliary information reported by the terminal. PDD reporting requires terminal location information and auxiliary information provided by the network device. Auxiliary information can include, for example, ephemeris information, common TA parameters, and k. mac Parameters, etc.

[0127] In some embodiments, the conditions for initiating RRM measurements in neighboring cells are as follows:

[0128] In IDLE or INACTIVE state:

[0129] Co-frequency neighboring cell measurement start condition: Srxlev <= SIntraSearchP or Squal <= SIntraSearchQ;

[0130] Inter-frequency / inter-system neighbor cell measurement initiation condition: Srxlev <= SnonIntraSearchP or Squal <= SnonIntraSearchQ.

[0131] Wherein, Srxlev is the serving cell signal received strength, SIntraSearchP is the reference signal received power (RSRP) threshold for co-frequency measurement, Squal is the serving cell signal quality, SIntraSearchQ is the co-frequency measurement trigger threshold for cell reselection, SnonIntraSearchP is the RSRP threshold for inter-frequency measurement, and SnonIntraSearchQ is the inter-frequency measurement trigger threshold for cell reselection.

[0132] In CONNECTED state:

[0133] When the RSRP value of the serving cell is lower than the measurement parameter, the terminal needs to enable the measurement of neighboring cells in the same frequency, the measurement of neighboring cells in different frequencies, or the measurement of neighboring cells in different systems.

[0134] In some embodiments, when the terminal is in a TN cell, the positioning function does not need to be constantly enabled for energy saving. However, the measurement of neighboring NTN cells requires the terminal's location information. In order to assist in TN-NTN mobility management, such as cell reselection (from TN cell to NTN cell) or handover from TN cell to NTN cell, keeping the positioning function constantly enabled in a TN cell is detrimental to the terminal's energy saving.

[0135] In order to balance terminal energy saving and ensure TN-NTN mobility, this disclosure provides the following communication methods, terminals, network devices, systems and storage media.

[0136] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0137] In step S2101, network device 102 sends instruction information to terminal 101.

[0138] In some embodiments, terminal 101 receives the instruction information.

[0139] In some embodiments, the indication information is used to indicate that terminal 101 is allowed to send first information to network device 102.

[0140] In some embodiments, the first information is used to assist the network device 102 in determining configuration information.

[0141] In some embodiments, the configuration information is used to configure a first parameter. The first parameter is a parameter related to a first condition, which is the condition for activating the location function. The specific content of the first parameter will be received in step S2104, and will not be described here.

[0142] In some embodiments, the name of the instruction information is not limited and can be interchanged with "permission to report instruction information", "permission information", etc.

[0143] In some embodiments, network device 102 sends indication information to terminal 101 when terminal 101 is allowed to send first information.

[0144] In some embodiments, network device 102 sends instruction information to terminal 101 when the load is low and / or computing resources are plentiful.

[0145] In some embodiments, network device 102 sends instruction information to terminal 101 when it is necessary to improve the reliability of configuration information.

[0146] In some embodiments, network device 102 may send instruction information to terminal 101 via system messages.

[0147] In some embodiments, network device 102 may send indication information to terminal 101 via signaling, wherein the signaling may include, but is not limited to, at least one of RRC signaling, Media Access Control-Control Element (MAC CE), and Downlink Control Information (DCI).

[0148] In some embodiments, step S2101 is an optional execution step. For example, when terminal 101 determines that it can send the first information based on a predefined method or when terminal 101 obtains instruction information from other execution entities, step S2101 may not be executed.

[0149] In step S2102, terminal 101 sends first information to network device 102.

[0150] In some embodiments, network device 102 receives the first information.

[0151] In some embodiments, the first information is used to assist the network device 102 in determining configuration information.

[0152] In some embodiments, the name of the first information is not limited and can be interchanged with "auxiliary information", "terminal auxiliary information", etc.

[0153] In some embodiments, the first information may include, but is not limited to, at least one of the following: a first mode; a first duration; and the first stabilization time (TTFF).

[0154] In one example, the first mode is the activation mode of the location function on terminal 101.

[0155] For example, the first mode can be any one of cold start mode, hot start mode, or warm start mode.

[0156] The cold start mode refers to a situation where the receiver for positioning does not save valid ephemeris data, valid time, and valid location information.

[0157] Among them, the warm start mode refers to the positioning function receiver storing historical ephemeris data, historical time information and historical location information, but the historical ephemeris data is invalid, so it is necessary to update the ephemeris data, which is faster than the cold start mode.

[0158] Among them, the hot start mode means that the receiver of the positioning function has stored valid ephemeris data, time and location information, and can locate immediately without updating the ephemeris data. The positioning speed of the hot start mode is the fastest.

[0159] In one example, the first duration is the startup duration of the location function.

[0160] For example, terminal 101 can estimate the duration for which the positioning function is activated in the first mode and obtain the first duration.

[0161] In one example, TTFF refers to the time between enabling location services and the time between enabling location services to output a valid navigation solution.

[0162] The above is merely an illustrative example, and this disclosure does not limit the content of the first information.

[0163] In some embodiments, when the terminal 101 is in a connected state, it can send the first information to the network device 102.

[0164] For example, terminal 101 can send the first information to network device 102 via RRC signaling.

[0165] In some embodiments, if the terminal 101 needs to disable the location function, it can send the first information to the network device 102.

[0166] In some embodiments, if the terminal 101 needs to enter a power-saving mode or energy-saving mode, it can send the first information to the network device 102.

[0167] In some embodiments, when terminal 101 receives instruction information, it may send the first information to network device 102.

[0168] In some embodiments, step S2103 is an optional execution step. For example, if network device 102 does not allow terminal 101 to send the first information or network device 102 obtains the first information from other execution entities, step S2102 may not be executed.

[0169] In step S2103, terminal 101 sends the modified first information to network device 102.

[0170] In some embodiments, network device 102 receives the modified first information.

[0171] In some embodiments, if the first information changes, the terminal 101 sends the modified first information to the network device.

[0172] In some embodiments, when the terminal 101 is in a connected state and the first information changes, it can send the changed first information to the network device 102.

[0173] In some embodiments, if the terminal 101 receives an instruction and the first information changes, it can send the changed first information to the network device 102.

[0174] In some embodiments, step S2103 is an optional step. For example, if the first information has not changed or the network device 102 does not allow the terminal 101 to send the first information, step S2103 may not be executed.

[0175] In step S2104, network device 102 sends configuration information to terminal 101.

[0176] In one example, the positioning function can be implemented using a Global Navigation Satellite System (GNSS) module.

[0177] In some embodiments, network device 102 is a network device in a terrestrial network.

[0178] In some embodiments, network device 102 may send configuration information to terminal 101 if the current area is within satellite coverage.

[0179] In some embodiments, network device 102 may send configuration information to terminal 101 if terminal 101 supports satellite communication.

[0180] In some embodiments, network device 102 may send configuration information to terminal 101 when it is necessary to obtain the location information of terminal 101.

[0181] In some embodiments, network device 102 may send a system message to terminal 101, which carries the configuration information.

[0182] In one example, when terminal 101 is in an inactive or idle state, network device 102 can send a system message to terminal 101, which carries the configuration information.

[0183] In one example, system messages may include, but are not limited to, SIBn, where n is a positive integer.

[0184] For example, the system message may be SIB19, or SIB3 or other SIBs, and this disclosure does not limit it.

[0185] In some embodiments, network device 102 may send a first signaling message to terminal 101, the first signaling message carrying the configuration information.

[0186] In one example, terminal 101 is in a connected state, and network device 102 can send a first signaling message to terminal 101, which carries the configuration information.

[0187] In one example, the first signaling may include, but is not limited to, at least one of RRC signaling, Media Access Control-Control Element (MAC CE), and Downlink Control Information (DCI).

[0188] For example, RRC signaling may include, but is not limited to, RRC reconfiguration messages.

[0189] In some embodiments, terminal 101 receives the configuration information.

[0190] In some embodiments, the terminal 101 receives the configuration information when the positioning function is not enabled.

[0191] In some embodiments, when the terminal 101 needs to obtain its own location information, it receives the configuration information.

[0192] In some embodiments, the terminal 101 may receive the configuration information when it is in power saving mode or energy-saving mode.

[0193] In some embodiments, the configuration information is used to configure a first parameter, which is a parameter related to a first condition, and the first condition is a condition for activating the positioning function. It can be understood that the first parameter being a parameter related to the first condition means that the first parameter can be used to determine whether the first condition is met, and thus, if the first condition is met, the positioning function is activated.

[0194] In some embodiments, the first parameter may include, but is not limited to, at least one of the following threshold values: a first threshold value; a second threshold value; a third threshold value; and a fourth threshold value.

[0195] In one example, the first threshold is the signal strength threshold or signal quality threshold of the serving cell.

[0196] For example, the signal strength threshold can be a threshold for Reference Signal Received Power (RSRP), and the signal quality threshold can be a threshold for Reference Signal Received Quality (RSRQ).

[0197] Accordingly, the first threshold value can be at least one of the following: the threshold value of RSRP; the threshold value of RSRQ.

[0198] For example, the first threshold value may be at least one of the following: an absolute threshold value of RSRP; a relative threshold value of RSRP; an absolute threshold value of RSRQ; a relative threshold value of RSRQ; a relative threshold value of RSRP for same-frequency measurement; a relative threshold value of RSRQ for same-frequency measurement; a relative threshold value of RSRP for different-frequency measurement; a relative threshold value of RSRQ for different-frequency measurement; or a relative value of a measurement configuration parameter.

[0199] Among them, the absolute threshold value can refer to the specific numerical value of the threshold, while the relative threshold value can refer to the relative numerical value of the absolute threshold value relative to a reference value.

[0200] Among them, the relative threshold value of RSRP for same-frequency measurement can refer to the relative threshold value of SIntraSearchP, the relative threshold value of RSRQ for same-frequency measurement can refer to the relative threshold value of SIntraSearchQ, the relative threshold value of RSRP for different-frequency measurement can refer to the relative threshold value of SnonIntraSearchP, and the relative threshold value of RSRQ for different-frequency measurement can refer to the relative threshold value of SnonIntraSearchQ.

[0201] The first threshold value may also be at least one of the following: the absolute threshold value of RSRP measured at the same frequency; the absolute threshold value of RSRQ measured at the same frequency; the absolute threshold value of RSRP measured at different frequencies; and the absolute threshold value of RSRQ measured at different frequencies.

[0202] The measurement configuration includes, but is not limited to, the measurement initiation s-measure parameter.

[0203] The first threshold value can also be the absolute value of the s-measure parameter.

[0204] It is understood that network device 102 can directly send an absolute threshold value, providing the specific threshold value to terminal 101. In order to save signaling resources, network device 102 can send a relative threshold value to terminal 101. This disclosure does not limit whether the first threshold value sent by network device 102 is an absolute value or a relative value.

[0205] In one example, the second threshold is the signal strength threshold or signal quality threshold of the first type of neighboring cell, where the first type of neighboring cell can be an NTN cell.

[0206] For example, the second threshold value may be at least one of the following: the RSRP threshold value of the first type of neighboring cell; the RSRQ threshold value of the first type of neighboring cell.

[0207] The second threshold value can also be an absolute threshold value or a relative threshold value, and this disclosure does not limit it.

[0208] In one example, the third threshold is the distance threshold between the first reference position and the second reference position.

[0209] The first reference location is situated within the serving cell, which is a TN cell. For example, the first reference location could be the center location of the serving cell where the terminal is currently located.

[0210] The second reference location is situated within a neighboring cell of the first type, which is a non-terrestrial communication (NTN) cell. For example, the second reference location could be the center location of an NTN neighboring cell of the currently serving cell.

[0211] In one example, the fourth threshold value is the time threshold value associated with the first time point.

[0212] The first time point is the time when the first type of neighboring cell begins to provide services. The first type of neighboring cell is the NTN cell.

[0213] For example, the fourth threshold value can indicate the absolute time of the first time point.

[0214] For example, the fourth threshold value can indicate the relative time from the current time point to the first time point, such as the time difference between the current time point and the first time point.

[0215] For example, the fourth threshold value can be other time threshold values ​​related to the first time point.

[0216] In some embodiments, network device 102 may determine configuration information based on a predefined method.

[0217] In some embodiments, network device 102 may determine configuration information based on first information sent by terminal 101.

[0218] In some embodiments, network device 102 may determine configuration information based on the modified first information sent by terminal 101.

[0219] In some embodiments, step S2104 is an optional execution step. For example, when terminal 101 determines the first parameter based on a predefined method, step S2104 may not be executed.

[0220] Step S2105: Terminal 101 starts the positioning function.

[0221] In some embodiments, if the terminal 101 determines that a first condition is met, it activates the positioning function, for example, by activating the GNSS module.

[0222] In some embodiments, the first parameter includes a threshold value. If the threshold value is met, the terminal 101 can determine that the first condition is met, and the positioning function can be activated at this time.

[0223] In one example, the first parameter includes a first threshold value. If the first threshold value is met, the terminal 101 determines that the first threshold value is met, that is, the first condition is met, and the positioning function can be started at this time.

[0224] For example, terminal 101 can determine a first value, and if the first value is less than a first threshold value, determine that the first threshold value is met. Here, the first value is the signal strength or signal quality value of the current serving cell measured by terminal 101.

[0225] For example, the first parameter includes a first threshold value, which is the absolute threshold value of RSRP, assuming it is RSRP#1. The signal strength value of the current serving cell measured by the terminal 101 is assumed to be RSRP#2. If RSRP#2 is less than RSRP#1, it means that the signal strength of the current serving cell is low, and the terminal 101 may trigger cell reselection or cell handover. At this time, the terminal 101 can determine that the first condition is met and start the GNSS module.

[0226] For example, the first parameter includes a first threshold value, which is the absolute threshold value of RSRQ, denoted as RSRQ#1. The signal quality value of the current serving cell measured by terminal 101 is denoted as RSRQ#2. If RSRQ#2 is less than RSRQ#1, it indicates that the signal quality of the current serving cell is poor, and terminal 101 may trigger cell reselection or cell handover. In this case, terminal 101 can determine that the first condition is met and activate the GNSS module. Of course, the first threshold value can also be a signal strength threshold value and a signal quality threshold value. Terminal 101 can determine that the first threshold value is met if the measured signal strength value of the current serving cell is less than the signal strength threshold value, and / or if the measured signal quality value of the current serving cell is less than the signal quality threshold value.

[0227] In one example, the first parameter includes a second threshold value. If the second threshold value is met, the terminal 101 determines that the second threshold value is met, that is, the first condition is met, and the positioning function can be started at this time.

[0228] For example, terminal 101 can determine a second value, and if the second value is greater than or equal to a second threshold value, determine that the second threshold value is met. Here, the second value is the signal strength or signal quality value of a first type of neighboring cell measured by terminal 101, and the first type of neighboring cell is an NTN cell.

[0229] For example, the first parameter includes a second threshold value, which is a relative threshold value of the signal quality RSRQ, assuming it is RSRQ#1. The terminal 101 measures the RSRQ value of the NTN neighboring cell of the current serving cell, assuming it is RSRQ#2. If RSRQ#2 is greater than or equal to RSRQ#1, it means that the signal quality of the NTN neighboring cell of the current serving cell is good. The terminal 101 may trigger cell reselection or cell handover. At this time, the terminal 101 can determine that the first condition is met and start the GNSS module.

[0230] Of course, the second threshold can also be a signal strength threshold and a signal quality threshold. Terminal 101 can determine that the second threshold is met if the measured signal strength value of the first type of neighboring cell is less than the signal strength threshold, and / or the measured signal quality value of the first type of neighboring cell is less than the signal quality threshold.

[0231] It is understandable that terminal 101 can measure the signal strength or signal quality value of the NTN neighboring cells of the current serving cell, i.e., the second value, without enabling the positioning function and / or without using SMTC adjustment.

[0232] In one example, the first parameter includes a third threshold value. If the third threshold value is met, the terminal 101 determines that the first condition is met, and the positioning function can be activated at this time.

[0233] For example, terminal 101 can determine a third value. If the third value is less than a third threshold value, it is determined that the third threshold value is met, i.e., the first condition is met, and the positioning function can be activated at this time. Here, the third value is the distance between the first reference position and the second reference position.

[0234] For example, the first parameter includes a third threshold value, which is d1. The terminal 101 measures the distance between the first reference position of the current serving cell and the second reference position of the NTN neighbor cell of the current serving cell, which is assumed to be d2. If d2 is less than d1, it means that the terminal 101 is close to the NTN cell and may trigger cell reselection or cell handover. At this time, the terminal 101 can determine that the first condition is met and start the GNSS module.

[0235] In one example, the first parameter includes a fourth threshold value. If the fourth threshold value is met, the terminal 101 determines that the first condition is met, and the positioning function can be activated at this time.

[0236] For example, if the fourth threshold value is reached, the terminal 101 can determine that the fourth threshold value is met, that is, the first condition is met, and at this time the positioning function can be activated.

[0237] For example, the first parameter includes a fourth threshold value. When the terminal 101 reaches the fourth threshold value, it can determine that the NTN neighboring cell has started to provide services. At this time, it can be determined that the first condition is met and the positioning function is started.

[0238] The above is merely an illustrative example, and this disclosure does not limit the scheme by which terminal 101 determines that the first condition is met.

[0239] In some embodiments, the first parameter includes multiple threshold values. If any one of the threshold values ​​is met, the terminal 101 can determine that the first condition is met, and the positioning function can be activated at this time.

[0240] The scheme for terminal 101 to determine that any one of the first threshold value, the second threshold value, the third threshold value, and the fourth threshold value is satisfied has been described in the foregoing embodiments and will not be repeated here.

[0241] For example, the first parameter includes a first threshold value and a fourth threshold value. If the first threshold value is met, the terminal 101 can determine that the first condition is met, and at this time, the positioning function can be activated. Alternatively, if the fourth threshold value is met, the terminal 101 can determine that the first condition is met, and at this time, the positioning function can be activated.

[0242] In some embodiments, the first parameter includes multiple threshold values. The terminal 101 can determine that the first condition is met if each of the multiple threshold values ​​is satisfied, and the positioning function can be activated at this time.

[0243] The scheme for terminal 101 to determine that any one of the first threshold value, the second threshold value, the third threshold value, and the fourth threshold value is satisfied has been described in the foregoing embodiments and will not be repeated here.

[0244] For example, the first parameter includes a first threshold value and a fourth threshold value. If the first threshold value and the fourth threshold value are satisfied, the terminal 101 can determine that the first condition is met, and the positioning function can be activated at this time.

[0245] In some embodiments, after the terminal 101 activates the positioning function, it can obtain its own location information and adjust the SMTC configuration based on the location information and auxiliary information broadcast by the network device, such as ephemeris information.

[0246] In some embodiments, after the terminal 101 activates the positioning function, it can obtain its own location information and, based on this location information and auxiliary information provided by the network device, such as ephemeris information, report PDD auxiliary information to the network device 102. The network device 102 can adjust the SMTC configuration according to the PDD auxiliary information.

[0255] Figure 3A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3A, the present disclosure relates to a communication method, which can be executed by terminal 101, and includes the following steps:

[0256] Step S3101: Obtain configuration information.

[0257] In some embodiments, terminal 101 receives configuration information sent by access network device 102, but is not limited thereto. Terminal 101 may also receive configuration information sent by other execution entities, such as relay devices or other terminals. In this case, step S3101 can be omitted.

[0258] In some embodiments, terminal 101 obtains configuration information specified by the protocol, in which case step S3101 is omitted.

[0266] In some embodiments, the execution order of steps S3101 to S3102 is not limited.

[0267] In the above embodiments, the terminal can activate the positioning function based on the configuration information sent by the network device, provided that the first condition for activating the positioning function is met. This can balance terminal energy saving and ensure TN-NTN mobility, thereby improving the availability and reliability of NTN technology.

[0268] Figure 3B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3B, the present disclosure relates to a communication method, which can be executed by a network device 102, and includes the following steps:

[0269] Step S3201: Send configuration information.

[0270] In some embodiments, network device 102 sends configuration information to terminal 101.

[0271] In some embodiments, terminal 101 receives configuration information.

[0272] In the above embodiments, the network device can send configuration information so that the terminal can activate the positioning function when the first condition for activating the positioning function is met. This can balance terminal energy saving and ensure TN-NTN mobility, thereby improving the availability and reliability of NTN technology.

[0273] The above process is further illustrated with examples below.

[0274] This disclosure provides a method for controlling a terminal to enable GNSS function to assist in the measurement of neighboring cells in an NTN cell under TN cell control, thereby achieving a balance between terminal energy saving and ensuring TN-NTN mobility.

[0275] 1. The terminal receives network configuration information, which includes conditional parameters for the auxiliary terminal to start the GNSS function. The terminal starts the GNSS function when the conditions are met.

[0276] 2. Based on 1, the condition parameters include the serving cell signal strength threshold or the signal quality threshold. The terminal meets the condition that the serving cell signal strength is less than the signal strength threshold or the serving cell signal quality is less than the signal quality threshold.

[0277] 3. Based on 2, the signal strength threshold can be the RSRP threshold, and the signal quality threshold can be the RSRQ threshold.

[0278] 4. Based on 1, condition parameters can be configured via system messages (such as SIB19 or SIB3 or other SIBs) or via RRC-specific signaling (such as RRC reconfiguration messages).

[0279] 5. Based on 3 and 4, when the conditional parameters are configured via system messages, the parameters can be absolute values ​​of RSRP and / or relative values ​​of RSRQ, or relative values ​​of parameters such as SIntraSearchP, SIntraSearchQ, SnonIntraSearchP, and SnonIntraSearchQ configured in SIB3.

[0280] 6. Based on 3 and 4, when the conditional parameters are configured via RRC dedicated signaling, the parameters can be absolute values ​​of RSRP or relative values ​​of the s-measure parameter in the measurement configuration.

[0281] 7. Based on 4, for connected terminals, the terminal can report GNSS auxiliary information to the network, such as the currently used GNSS module startup mode (e.g., cold start, warm start, or hot start) and / or GNSS module startup time and / or first settling time (TTFF). The network configures the corresponding GNSS function startup condition parameters according to the GNSS auxiliary information reported by the terminal.

[0282] 8. Based on 7, when the aforementioned GNSS auxiliary information changes on the terminal side (e.g., the GNSS module startup mode changes), the terminal reports the updated auxiliary information to the network.

[0283] 9. Based on 7, when the network configuration allows the terminal to report GNSS auxiliary information, the terminal reports GNSS auxiliary information to the network.

[0284] 10. Based on 1, the condition parameters also include a signal strength threshold or signal quality threshold for NTN neighboring cells. The terminal satisfies the condition if: the signal strength of the NTN neighboring cell is higher than the signal strength threshold, or the signal quality of the NTN neighboring cell is higher than the signal quality threshold. The signal quality of the NTN neighboring cell can be the signal quality of any currently measurable NTN neighboring cell (e.g., measured without GNSS functionality enabled and / or without SMTC adjustment).

[0285] 11. Based on 1, the condition parameter further includes an NTN neighbor cell distance threshold, such as a distance threshold between the serving cell reference point and the NTN neighbor cell (e.g., earth moving cell) reference point, wherein the condition is satisfied that the distance between the serving cell reference point and the NTN neighbor cell reference point is less than the threshold.

[0286] 12. Based on 1, the condition parameter further includes an NTN neighbor cell time threshold, such as a time threshold related to the service time of the NTN neighbor cells (e.g., before or after). The condition is satisfied when the time threshold is reached.

[0287] 13. Based on 2, 10, 11 and 12, when the network is configured with two or more of these thresholds, the terminal satisfies the condition by satisfying any one of these thresholds.

[0288] 14. Based on 2, 10, 11 and 12, when the network is configured with two or more of these thresholds, the terminal satisfies the following conditions: satisfies all configured thresholds.

[0289] 15. Based on 4, for terminals in IDLE or INACTIVE state, the TN network can also indicate the GNSS module startup mode of the terminal through system messages, such as one of cold start, warm start, or hot start.

[0290] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0291] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0292] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
