Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to an auxiliary information receiving and reporting method and device. BACKGROUND

[0002] In related technologies, enhancement schemes for handover and random access processes in non-terrestrial networks (NTN) are discussed, but the effectiveness of the configurations corresponding to different processes configured by the network node to the terminal is rarely involved, and this problem is particularly important in the scenario of high-speed satellite movement, because in this scenario, the replacement speed of the serving satellite will be relatively frequent.

[0003] Because the satellite can move very fast, the effectiveness of some configurations configured by the network node to the terminal, such as configurations required for the handover process and configurations required for the random access process, can be reduced. For example, for the handover process, premature or late handover problems can occur, and for late handover execution, radio link failure (RLF) can occur. For the random access process, the terminal can always fail to access on the current random access resource or the probability of successful access can be very small. SUMMARY

[0446] The technical solutions of the present application will be further described below in combination with the drawings and specific embodiments.

[0447] 1. For the problem of early switching:

[0448] Based on the network side (i.e. network side device), whether to adjust the switching configuration information and / or the sending time of the switching command can be determined:

[0449] Optionally, the terminal periodically reports the network assistance information, and the network side device determines whether the switching configuration information sent to the terminal and / or the time of the switching command needs to be re-adjusted according to the network assistance information.

[0450] Alternatively, the network side device instructs the terminal to report the network assistance information every period of time, so as to determine whether the switching configuration information sent to the terminal and / or the time of the switching command needs to be re-adjusted.

[0451] Or the terminal reports network assistance information to the network based on event triggering, and the event can be at least one of the following:

[0452] The terminal detects that the signal quality (RSRP / RSRQ) of the source serving satellite after several consecutive handover completions is greater than a certain threshold value;

[0453] The terminal detects that the distance from the terminal to the center of the coverage of the source serving satellite after several consecutive handover completions is less than a certain threshold value;

[0454] The terminal detects that the distance from the terminal to the edge of the coverage of the source serving satellite after several consecutive handover completions is greater than a certain threshold value;

[0455] The terminal detects that the distance from the terminal to the source serving satellite after several consecutive handover completions is less than a certain threshold value;

[0456] The terminal detects that the elevation angle of the source serving satellite after several consecutive handover completions is within a certain range.

[0457] The specific number of "several times" of the above different events and the corresponding threshold value and / or range are configured by the network side to the terminal

[0458] Based on the terminal, it can be determined whether to adjust the handover configuration information and / or the sending time of the handover command:

[0459] Optionally, the terminal periodically determines whether to request the network side to adjust the handover configuration information and / or the sending time of the handover command sent to the terminal according to the related threshold value configured by the network side, and if the terminal side determines that it is necessary, it requests the network side to adjust the handover configuration information and / or the sending time of the handover command sent to the terminal;

[0460] Or the terminal determines whether to request the network side to adjust the handover configuration information and / or the sending time of the handover command sent to the terminal according to the related threshold value configured by the network side based on event triggering, and if the terminal side determines that it is necessary, it requests the network side to adjust the handover configuration information and / or the sending time of the handover command sent to the terminal, and the event is described above based on the network side decision.

[0461] Among them, the network assistance information should at least include at least one of the following:

[0462] The duration that the signal quality RSRP / RSRQ of the source serving satellite after several consecutive handover completions is greater than a certain threshold value;

[0463] The duration that the distance from the terminal to the center of the coverage of the source serving satellite after several consecutive handover completions is less than a certain threshold value;

[0464] The duration that the distance from the terminal to the edge of the coverage of the source serving satellite after several consecutive handover completions is greater than a certain threshold value;

[0465] the duration that the distance between the terminal and the source serving satellite is less than a certain threshold after the last completed handover;

[0466] the duration that the elevation angle of the source serving satellite is within a certain range after the last completed handover.

[0467] the number of times and the corresponding threshold in the above different assistance information are configured by the network side

[0468] For example, as shown in the above reporting the elevation angle assistance information and the network side determining, it includes: Figure 1

[0469] Step 1: the terminal reports the duration that the elevation angle of the source serving satellite is within a certain range after the last completed handover;

[0470] Step 2: the network side determines whether the number of times that the duration is greater than a certain threshold 11 exceeds a threshold 12;

[0471] Step 3: the terminal adjusts the handover configuration and / or the sending timing of the handover command backward.

[0472] The elevation angle range in step 1 and the thresholds 11, 12 in step 2 are configured by the network side.

[0473] The determination method of the threshold 11: the network side determines according to the relative moving speed of the satellite service remaining time (calculated by the terminal according to the terminal position information, satellite ephemeris information and terminal moving speed, and reported to the network side by the terminal) and / or satellite moving speed (contained in satellite ephemeris information) and terminal moving speed, the smaller the satellite service remaining time and / or the faster the relative moving speed of the satellite and the terminal, the smaller the value of the threshold 11 should be.

[0474] The determination method of the threshold 12: the network side determines according to the QoS of the main service data type transmitted with the terminal, if the QoS requirement is higher, the value of the threshold 12 should be smaller.

[0475] For example, as shown in the above reporting the elevation angle assistance information and the terminal side determining, it includes: Figure 2

[0476] Step 1: the network side configures the comparison threshold 11 of the duration and the comparison threshold 12 of the number of times that the duration is greater than a certain threshold 11 to the terminal;

[0477] Step 2: the terminal side determines whether the number of times that the duration that the elevation angle of the source serving satellite is within a certain range after the last completed handover is greater than a certain threshold 11 exceeds a threshold 12;

[0478] Step 3: the terminal side requests the network side to adjust the handover configuration and / or the sending timing of the handover command backward.​​

[0479] Step4: The network side receives the request from the terminal side, and executes the sending timing adjustment of the handover configuration and / or handover command.

[0480] 2. For the problem of too late handover:

[0481] Based on the network side (i.e. network side device) can determine whether to adjust the sending timing of the handover configuration information and / or handover command:

[0482] Optionally, the terminal periodically reports the network assistance information to the network, and the network side re-adjusts the sending timing of the handover configuration information and / or handover command to the terminal.

[0483] Or, the network side indicates the terminal to report the network assistance information every period of time, so as to determine whether the sending timing of the handover configuration information and / or handover command to the terminal needs to be re-adjusted.

[0484] Or the terminal reports the network assistance information based on event triggering, and the event can be at least one of the following:

[0485] The terminal detects that the signal quality (RSRP / RSRQ) of the source service satellite is less than a certain threshold value when starting to perform handover to completing handover for several times in succession;

[0486] The terminal detects that the distance from the terminal to the center of the coverage of the source service satellite is greater than a certain threshold value when starting to perform handover to completing handover for several times in succession;

[0487] The terminal detects that the distance from the terminal to the edge of the coverage of the source service satellite is less than a certain threshold value when starting to perform handover to completing handover for several times in succession;

[0488] The terminal detects that the distance from the terminal to the source service satellite is greater than a certain threshold value when starting to perform handover to completing handover for several times in succession;

[0489] The terminal detects that the elevation angle of the source service satellite is outside a certain range when starting to perform handover to completing handover for several times in succession.

[0490] The specific number of times of the above different events "for several times in succession" and the corresponding threshold value and / or range are configured to the terminal by the network side

[0491] Based on the terminal can determine whether to adjust the sending timing of the handover configuration information and / or handover command:

[0492] Optionally, the terminal periodically determines whether the sending timing of the handover configuration information and / or handover command to the terminal needs to be adjusted according to the related threshold value configured by the network side, and if the terminal side determines that it needs to be adjusted, the terminal side requests the network side to adjust the sending timing of the handover configuration information and / or handover command to the terminal.

[0493] Or the terminal determines whether to request the network side to adjust the switching configuration information and / or the switching command based on the event triggered according to the relevant threshold value configured by the network side, and if the terminal side determines that it is necessary, it requests the network side to adjust the switching configuration information and / or the switching command sent to the terminal. The time of the event is based on the description in the network side decision above.

[0494] The network assistance information should at least include the following at least one:

[0495] The duration of the signal quality RSRP / RSRQ of the source service satellite being less than a certain threshold value from the start of the execution of the switching to the completion of the switching in the last few times;

[0496] The duration of the distance from the terminal to the center of the coverage of the source service satellite being greater than a certain threshold value from the start of the execution of the switching to the completion of the switching in the last few times;

[0497] The duration of the distance from the terminal to the edge of the coverage of the source service satellite being less than a certain threshold value from the start of the execution of the switching to the completion of the switching in the last few times;

[0498] The duration of the distance from the terminal to the source service satellite being greater than a certain threshold value from the start of the execution of the switching to the completion of the switching in the last few times;

[0499] The duration of the elevation angle of the source service satellite being outside a certain range from the start of the execution of the switching to the completion of the switching in the last few times.

[0500] The number of statistics and the corresponding threshold value in the above different assistance information are configured by the network side.

[0501] The above reports the distance from the terminal to the source service satellite assistance information and is decided by the network side, as shown in Figure 3 , including:

[0502] Step 1: The terminal reports the duration of the distance from the terminal to the source service satellite being greater than a certain threshold value 8 from the start of the execution of the switching to the completion of the switching in the last few times;

[0503] Step 2: The network side determines whether the number of times that the duration is greater than a certain threshold value 13 exceeds a threshold value 14;

[0504] Step 3: The terminal adjusts the sending time of the switching configuration and / or the switching command.

[0505] Wherein the threshold values 8, 13, and 14 are configured by the network side.

[0506] The determination method of threshold 13: determined by the network side according to the relative moving speed between the satellite service remaining time (calculated by the terminal according to the terminal position information, satellite ephemeris information and terminal moving speed, and reported to the network side by the terminal) and / or satellite moving speed (contained in the satellite ephemeris information) and terminal moving speed. The smaller the satellite service remaining time and / or the faster the relative moving speed between the satellite and the terminal, the smaller the value of threshold 13 should be.

[0507] The determination method of threshold 14: determined by the network side according to the QoS of the main service data type transmitted with the terminal. The higher the QoS requirement, the smaller the value of threshold 14 should be.

[0508] The above reports the terminal to the source service satellite distance auxiliary information and is determined by the terminal side. As shown in Figure 4 , including:

[0509] Step 1: The network side configures the terminal with the duration comparison threshold 13 and the number of times the duration greater than a certain threshold 13 is greater than a certain threshold 14.

[0510] Step 2: The terminal determines whether the number of times the duration greater than a certain threshold 13 from the start of the handover to the completion of the handover is greater than a certain threshold 13 is greater than a certain threshold 14.

[0511] Step 3: The terminal side requests the network side to forward adjust the handover configuration and / or the sending time of the handover command.

[0512] Step 4: After receiving the request from the terminal side, the network side executes the forward adjustment of the handover configuration and / or the sending time of the handover command.

[0513] 3. For the problem that random access always fails or the access success probability is low.

[0514] If the terminal always fails in random access or the probability of successful access is very small within a period of time, the terminal reports the network assistance information to the network node (i.e. the network side device) to request new random access resource configuration.

[0515] The network assistance information should at least include: the total number of attempts to random access within a period of time or the probability or number of failed or successful access without limiting the length of the statistical time;

[0516] Alternatively, without limiting the length of the statistical time, the network side can directly instruct the terminal to report the probability or number of failed or successful access within a certain number of consecutive attempts to random access.

[0517] The network side adjusts according to the assistance information reported by the terminal: the judgment method for the case of limiting the length of the statistical time is as follows:

[0518] 1) The network node determines that the statistical duration of the terminal is too short (such as a scenario where satellite coverage is discontinuous), and indicates a new statistical duration value for the terminal;

[0519] 2) The network node determines that the statistical duration of the terminal is too long (such as a scenario where satellite coverage is relatively dense), and the probability of successful access of the terminal within the time period is less than a certain threshold (or the probability of access failure is greater than a certain threshold), and the network indicates a new statistical duration value for the terminal and reconfigures new random access resources for the terminal;

[0520] 3) Under the premise that the network node determines that the statistical duration of the terminal is reasonable, the network node determines that the probability of successful access of the terminal within a period of time is less than a certain threshold (or the probability of access failure is greater than a certain threshold), and reconfigures new random access resources for the terminal.

[0521] The determination of the reasonableness of the statistical duration in the above 1) to 3) is determined by the network side according to constellation deployment information and / or ephemeris information, such as the more sparse the constellation deployment, the longer the statistical duration should be.

[0522] For the case of not limiting the statistical duration, the network side compares the probability or number of failed or successful access within a certain number of consecutive attempts of random access reported by the terminal with a certain threshold to determine whether to configure new random access resources for the terminal.

[0523] Access success or access failure probability calculation method: the terminal reports Random Access problem to the upper layer after the preamble sending attempt number reaches the maximum value, and counts the access failure probability within a period of time according to the total number of random access executions and the number of Random Access problem reported to the upper layer

[0524] The embodiment of the application also provides an auxiliary information receiving device applied to a network side device, such as Figure 5 as shown, comprising a processor 12 and a transceiver 11,
