[0002] In non-terrestrial networks (NTNs), when a terminal initiates random access, it has not established a connection with the network or is in a state of temporary connection interruption.

Moreover, to help the terminal use appropriate parameters to send or receive two-step or four-step random access related messages, NTN cells may broadcast some parameters, but the initial settings of these parameters may not be accurate or reasonable.

[0236] The present invention will now be described in conjunction with specific scenario examples.

[0237] This embodiment proposes a method for optimizing relevant parameters on the network side based on information recorded and reported by the terminal regarding random access. For example... Figure 5 As shown, the method includes:

[0238] Step 501: The network side (network management or TCE (Trace Collection Entity) or base station) configures NTN UE to record random access related information; it should be noted that this step is optional.

[0239] Specifically, the network-side configuration may include one or more of the following:

[0240] Does the terminal have location capabilities, that is, can the UE obtain its own location information?

[0241] For UEs without location capabilities, the UE records and reports the extended length or the extended multiple of the ra-ContentionResolutionTimer configured on the network side, and / or the length or the extended multiple of the ra-ResponsWindow, and / or the reference TA value of the common broadcast by the base station, or information related to the extension of the TA offset broadcast in the system information.

[0242] If the UE uses a four-step RA, the network side configures NTN UE record random access related information including one or more of the following: record the RO opportunities used by the UE (especially time domain information), the preamble code, the time offset of the ra-ResponseWindow configured by the base station (i.e., how long after the UE sends the preamble does it start listening for RAR (msg 2)), whether the UE receives RAR after sending the preamble, or how long it takes to receive RAR, or the time difference from starting to listen for RAR to receiving RAR;

[0243] If the UE uses a two-step RA, the network side configures NTN to record random access related information for the UE, including one or more of the following: record the time window offset and length extension configured by the base station for receiving msgB, whether the UE receives msgB, and the time difference between receiving msgB and msgA;

[0244] Configure the random access mechanism (two-step, four-step, RACH-less) or random access resources (preamble code or preamble code packet information, RO time-frequency resources) used by the UE on the network side;

[0245] The TA threshold value (i.e., the UE can only initiate a two-step RA if its TA value exceeds this threshold value) and / or RSRP threshold value (i.e., the UE can only initiate a two-step RA if its RSRP value exceeds this threshold value), and / or the actual values ​​of TA and / or RSRP when the UE initiates a two-step or four-step RA.

[0246] The threshold of the trigger condition reported by TA (i.e., the TA is reported when the change value exceeds the threshold) and / or the hysteresis time, and / or the period of TA reporting, and / or the success rate of data reception or transmission (so that the network can determine whether to update the threshold and hysteresis of the trigger condition reported by TA based on the effect of UE uplink synchronization, thereby better reducing signaling overhead and power consumption).

[0247] The UE records and reports the number of times the UE selects a two-step RA and / or a four-step RA;

[0248] The UE records and reports whether a two-step RA fallback to a four-step RA has occurred, or the number of times a two-step RA fallback to a four-step RA has occurred, such as the number of times a fallback RAR has been received (this information can be used to determine whether the network has experienced random access resource congestion).

[0249] The UE records and reports the number of successes and / or failures corresponding to two-step RA or four-step RA;

[0250] The UE records and reports the access delay corresponding to the two-step RA or four-step RA and / or the corresponding UE-to-satellite transmission delay, and / or the corresponding recorded statistical duration.

[0251] Step 502: The UE records the relevant information of the above random access;

[0252] Here, this information may be configured by the network management system, TCE, or base station, or it may be specified in the protocol.

[0253] Step 503: The UE reports the relevant information of the random access through a newly configured message or in the random access report while in connected state, during the transition to connected state, or in idle / inactive state;

[0254] Here, the reporting includes any of the following situations:

[0255] Reporting is based on network-side requests;

[0256] The UE proactively reports the information.

[0257] After the UE informs the network side of the relevant log information, it sends the logs at the network side's request.

[0258] Step 504: The network side performs corresponding network coverage and parameter optimization based on the random access information reported by the terminal; specifically, the optimization process includes, but is not limited to, one or more of the following:

[0259] The network side can determine whether the TA value broadcast by the base station is reasonable for UEs without location information (e.g., many UEs still cannot achieve uplink synchronization or the uplink synchronization is not accurate after using this reference TA value), or whether the extension setting of the TA offset broadcast in the system information is reasonable, or whether the length of ra-ResponseWindow (e.g., if a large number of UEs do not receive RAR, it may be configured too short) or ra-ContentionResolutionTimer after extension (e.g., if a large number of UEs do not receive msg4, it may be configured too short). If a large number of UEs report that the aforementioned problems or even RA failures occur after using these parameters, adjustments need to be made according to the failure situation.

[0260] For a four-step RA, the network side can determine whether the time offset and extension length of the ra-ResponseWindow configured by the base station are reasonable. If a large number of UEs receive RAR a long time after the RAR reception window is opened, or even do not receive RAR at all (because the actual RAR arrives later), the network side should increase the offset and / or length; conversely, if a large number of UEs receive RAR quickly after the RAR reception window is opened, or do not receive RAR at all (because the actual RAR arrives too early), the network side should decrease the offset and / or length. For a two-step RA, the network side can determine whether the time window length or offset configured for receiving msgB for the UE is appropriate; the determination and adjustment mechanism is similar to that of the four-step RA.

[0261] By combining the probability of successful RA, the network side can determine whether RO overlap and confusion has occurred, and thus adjust the preamble and / or RO grouping or allocation;

[0262] Based on the threshold and hysteresis of the triggering conditions reported by the TA, or the reporting period of the TA, and the success rate of data reception or transmission, the network can determine whether it is necessary to update the threshold and hysteresis of the triggering conditions reported by the TA based on the uplink synchronization effect of the UE, thereby better reducing signaling overhead and power consumption.

[0263] The network side can determine whether the network has experienced random access resource congestion, whether the TA threshold and RSRP threshold are properly configured, and whether adjustments are needed, based on the number of successful RACH steps and / or failed RACH steps reported by the UE, the number of times the RACH steps were back to the four-step RACH, the corresponding access latency, and / or the corresponding UE-to-satellite transmission latency, and / or the statistical duration of the corresponding records.

[0264] If the number of two-step RACH failures or the number of two-step fallbacks to four-step RACH reported by the UE is found to be greater than a certain value, it indicates that the two-step RA UL is congested. In this case, the TA threshold is increased to reduce the chance of two-step RA occurring. On the other hand, if the number of two-step RA failures or the number of two-step fallbacks to four-step RACH reported by the UE is found to be less than a certain value, but the average access delay of random access reported by the UE is greater than a certain value, the TA threshold is decreased to increase the chance of two-step random access.

[0265] The random access information recorded and reported by the terminal in this embodiment of the invention can help the network side configure reasonable NTN random access parameters, thereby reducing signaling overhead and power consumption.

[0266] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
