Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a method, device, apparatus, and storage medium for information reporting. Background Art

[0002] Self-Organizing Network (SON) and / or Minimization of Drive Test (MDT) related reports are various record contents sent by a terminal (or user equipment, UE) to the network side, including Radio Link Failure (RLF) or Handover Failure (HOF) reports, Connection Establishment Failure (CEF) reports, Mobility History Information (MHI) reports, Random Access Channel (RACH) reports, Successful Handover Report (SHR), Successful PSCell change or addition Report (SPR), Logged MDT reports, Immediate MDT reports, etc. These SON and / or MDT related reports can be used to optimize the parameters or configuration information of each node on the access network side, or to collect big data for analysis by operators.

[0003] In SON and / or MDT related reports, the terminal needs to carry information about the unique Tracking Area (TA) where the terminal is located when the relevant report content is recorded. However, for a Non-Terrestrial Network (NTN) cell that broadcasts multiple TAs, the terminal cannot determine its unique TA. In this case, there is no clear solution on how the terminal reports TA information. Summary of the Invention

[0150] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0151] In the embodiments of the present application, the term "a plurality of" means two or more, and other quantifiers are similar thereto.

[0152] In the embodiments of the present application, terms such as "first" and "second" are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple.

[0153] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0154] To facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical content related to the embodiments of the present application will be introduced first.

[0155] In the traditional way of updating the Tracking Area Identity (TAI) (hard TAI update: which means each cell broadcasts only one registration area identity), when the cell moves with the satellite across the registration area boundary, it may cause the border UEs to update the registration area back and forth. Figure 1 The following is an example diagram of the traditional TAI update provided by the related art, as Figure 1 shown. Due to the movement of the satellite, the terminal is in the areas corresponding to different Tracking Area Codes (TACs) at different times. For example, at time T1, the terminal is in the area corresponding to TAC2; at time T2, the terminal is in the area corresponding to TAC1; at time T3, the terminal is in the area corresponding to TAC2. This will cause the terminal to frequently update the registration area, increasing unnecessary signaling overhead.

[0156] To reduce the paging overhead of frequent registration area updates caused when the cell crosses the registration area boundary, a soft TAI update solution is introduced for scenarios such as non-terrestrial network (NTN) Earth moving: each cell can broadcast more than one TA list for each Public Land Mobile Network (PLMN), and the TA area is bound to the terrestrial fixed area. When the UE moves within the TA list, the registration area update process caused by changing the TA will not be triggered. Only when the UE moves out of the TA list broadcast by the network, the UE will trigger the registration area update process. Figure 2 The following is an example diagram of the soft TAI update provided by the related art, as Figure 2 shown. For the cells in the boundary area between TA1 and TA2, the network broadcasts the TAIs of TA1 and TA2, that is, TAI1 and TAI2. Thus, when the UE moves within the TA1 and TA2 areas, the registration area update process caused by changing the TA will not be triggered.

[0157] In the case of network broadcast with multiple TAs, the base station node needs to report all broadcast TAI to the core network node (such as the Access and Mobility Management Function (AMF)), and (if available) the TAI mapped according to the UE geographical location. For this purpose, two parts of optional information are added to the NG interface message of the related technology: an additional TAI list for transmitting multiple broadcast TAIs (consistent with the TAI list broadcast on the air interface), and a single TAI mapped according to the possible UE geographical location.

[0158] Regarding the TA information used to identify the location area of the backhaul cell, the related technology requires reporting a unique TA identifier in the SON and / or MDT related reports. However, in the NTN network, multiple TAs may be broadcast in one cell, and it is not clear how to report the TA information in this case.

[0159] Figure 3 One of the flow diagrams of the information reporting method provided by the embodiments of this application, this method is applied to a terminal, such as Figure 3 As shown, this method includes the following steps:

[0160] Step 300, in the case of multiple Tracking Areas (TAs) being broadcast in a Non-Terrestrial Network (NTN) cell, send a Self-Organizing Network (SON) and / or Minimization of Drive Tests (MDT) related report for the NTN cell to the network device, and the SON and / or MDT related report contains the information of a first TA or the information of multiple second TAs.

[0161] Specifically, in this application, for an NTN cell that broadcasts multiple TAs, when the terminal reports the SON and / or MDT related report related to the NTN cell, it can carry the information of a first TA or the information of multiple second TAs in the SON and / or MDT related report. The first TA or the multiple second TAs are used to indicate the TA range where the terminal is located. The network side can determine the single TA where the terminal is located based on the information of the first TA or the information of the multiple second TAs, or narrow the TA range as much as possible when determining the TA where the terminal is located.

[0162] Among them, broadcasting multiple TAs means broadcasting multiple TAs for one cell (corresponding to one cell identity).

[0163] In some embodiments, broadcasting multiple TAs can be broadcasting a TA list, and the TA list contains multiple TAs.

[0164] In this application, the SON and / or MDT-related reports may include various reports related to SON and / or MDT, and this application does not make specific limitations thereon. For example, the SON and / or MDT-related reports may include: RLF or HOF reports, CEF reports, MHI reports, RACH reports, SHR, SPR, Logged MDT reports, Immediate MDT reports, etc.

[0165] This application does not limit the specific TAs referred to by the first TA and the second TA, as long as they can be used to indicate the TA range where the terminal is located to the network side.

[0166] For the scenario of NTN cell broadcasting multiple TAs, in the information reporting method provided by the embodiments of this application, the terminal may carry the information of a first TA or the information of multiple second TAs when reporting SON and / or MDT-related reports, so that the network side can determine the single TA where the terminal is located based on the information of the first TA or the information of the multiple second TAs, or can narrow down the TA range as much as possible when determining the TA where the terminal is located, thereby contributing to subsequent network optimization or big data analysis.

[0167] In some embodiments, the first TA is any one of the following:

[0168] (1) The TA where the terminal is located derived by the terminal based on the geographical location of the terminal.

[0169] For example, if the terminal can derive the single TA where it is located based on its own geographical location, the terminal may report the information of this TA, such as TAI, in the SON and / or MDT-related report. The network side can determine the TA where the terminal is located according to the information of this TA.

[0170] It can be understood that the TA where the terminal is located derived by the terminal based on its own geographical location is one of the multiple TAs broadcast by the NTN cell.

[0171] In some embodiments, the terminal may report the geographical location information of the terminal to the network side, and the network side may map according to the geographical location information of the terminal to obtain the TA where the terminal is actually located when executing the record report content.

[0172] (2) A specific TA in the TA list broadcast by the NTN cell. This application does not limit which TA in the TA list the specific TA is, as long as the terminal and the network side have a consistent understanding of this specific TA.

[0173] For example, the specific TA may be the first TA, the last TA, or the TA in the middle in the TA list, etc.

[0174] The network side can determine which TA list the specific TA belongs to based on the specific TA, and then determine the single TA where the terminal is located from the TA list based on other information, or further narrow down the TA range based on the TA list.

[0175] (3) The specific TA among multiple TAs that the terminal can access. This application does not limit which specific TA among the TAs that the terminal can access, as long as the terminal and the network side have a consistent understanding of the specific TA. For example, the specific TA can be the first TA in the TA list that the terminal can access.

[0176] The network side can determine which terminal-accessible TA list the specific TA belongs to based on the specific TA, and then determine the single TA where the terminal is located from the terminal-accessible TA list based on other information, or further narrow down the TA range based on the terminal-accessible TA list. The terminal and the network side can determine the terminal-accessible TA list in the same way to ensure a consistent understanding of the terminal-accessible TA list.

[0177] For example, the terminal can determine the intersection of the TA list broadcast by the network received by the Access Stratum (AS) of the terminal and the TAI list received by the Non-Access Stratum (NAS) of the terminal during processes such as mobile registration update, and use the TAs in this intersection as the TAs that the terminal can access.

[0178] Alternatively, the terminal can exclude the TAs that are prohibited for the terminal to access from the list of Forbidden Tracking Areas obtained from the NAS layer of the terminal in the TA list broadcast by the network received by the AS layer of the terminal, and use the remaining TAs after excluding the prohibited access TAs as the TAs that the terminal can access.

[0179] Alternatively, the terminal can use both the TAs in the above intersection and the remaining TAs after excluding the prohibited access TAs as the TAs that the terminal can access.

[0180] In some embodiments, the list of forbidden tracking areas includes: 5GS forbidden tracking areas for roaming in the 5G network, and / or, 5GS forbidden tracking areas for regional provision of service in the 5G network.

[0181] (4) The only one TA that the terminal can access.

[0182] For example, if there is only one TA accessible to the terminal, the terminal may report information about the one TA accessible to the terminal in a SON and / or MDT related report, and the network side may determine the TA where the terminal is located based on the information about the TA.

[0183] By reporting the information of a single TA, signaling overhead can be saved, and the multiple optional solutions for the first TA also improve the flexibility of TA information reporting.

[0184] In some embodiments, the plurality of second TAs are any of the following:

[0185] (1) All TAs in the TA list broadcast by the NTN cell.

[0186] In this case, the network side may determine a single TA where the terminal is located from the TAs reported by the terminal based on other information, or further narrow the TA range based on the TAs reported by the terminal.

[0187] (2) Multiple TAs that a terminal can access.

[0188] For the multiple TAs accessible to the terminal, please refer to the above description of the TA accessible to the terminal (or the list of TAs accessible to the terminal), which will not be repeated here.

[0189] In some embodiments, the TAs accessible to the terminal include:

[0190] The intersection of the TA list broadcast by the NTN cell and the TA list received by the NAS layer of the terminal; and / or other TAs in the TA list broadcast by the NTN cell except the TAs prohibited from accessing by the terminal.

[0191] For example, the terminal can determine the intersection of the TA list broadcast by the network received by the terminal's AS layer and the TAI list received by the terminal's NAS layer from processes such as mobile registration update, and use the TA in the intersection as the terminal-accessible TA; or, the terminal can exclude the TAs prohibited from terminal access in the prohibited tracking area list obtained from the terminal's NAS layer from the TA list broadcast by the network received by the terminal's AS layer, and use the TAs remaining after excluding the prohibited access TAs as the terminal-accessible TAs; or, the terminal can use the TA in the above-mentioned intersection and the TA remaining after excluding the prohibited access TAs as the terminal-accessible TAs.

[0192] By reporting multiple second TAs instead of a specific TA, subsequent processing operations on the network side can be reduced, the complexity of network side processing is reduced, and it helps the network side to more accurately determine the TA range of the terminal, thereby improving the accuracy of subsequent network optimization or big data analysis.

[0193] In some embodiments, the SON and / or MDT related reports further include the quantity information of multiple TAs broadcast by the NTN cell, that is, the terminal also reports the quantity of TAs broadcast by the NTN cell, which provides more auxiliary information for the network side to judge the TA range where the terminal is located, enabling the network side to more accurately judge the TA range where the terminal is located.

[0194] In some embodiments, when the terminal reports a specific TA in the TA list broadcast by the NTN cell, it can simultaneously report the quantity of TAs in the TA list to help the network side more accurately determine which TA list the specific TA belongs to.

[0195] In some embodiments, sending the SON and / or MDT related reports for the NTN cell to the network device includes:

[0196] Sending the SON and / or MDT related reports for the NTN cell to the network device through a first message, where the first message includes the time information of the time when the terminal records the report content of the SON and / or MDT related reports.

[0197] For example, the terminal can carry the time information of the time when the terminal records the report content of the SON and / or MDT related reports in the SON and / or MDT related reports, or the terminal can report the time information and the SON and / or MDT related reports together through the first message outside the SON and / or MDT related reports.

[0198] When the terminal reports the time information of the time when it records the report content of the SON and / or MDT related reports, it can assist the subsequent network side nodes to specifically analyze the information corresponding to the corresponding moment when they receive the SON and / or MDT related reports of the terminal. For example, using the ephemeris information corresponding to the recording moment generated by the terminal, the geographical location information reported by the terminal, etc., to determine the cell where the terminal is located at that time, the location within the cell, the actual TA, the location within the actual TA, etc.

[0199] By reporting the time information of the time when the terminal records the report content of the SON and / or MDT related reports, the network side can know the accurate moment when the terminal records the report content of the SON and / or MDT related reports, so that it can conduct a more comprehensive analysis in combination with other information corresponding to the corresponding moment, improving the accuracy of the network side's judgment of the TA range where the terminal is located.

[0200] In some embodiments, the time information includes:

[0201] (1) Absolute time information, which is the absolute time at which the terminal records the report content of the SON and / or MDT-related report. The specific time format of the absolute time information is not limited in this application. For example, it can be an absolute time in the Global Positioning System (GPS) time format, an absolute time in the Coordinated Universal Time (UTC) time format, etc.

[0202] Reporting the time information of the terminal recording the report content of the SON and / or MDT related report in the form of absolute time information can reduce subsequent processing operations on the network side and reduce the complexity of network side processing.

[0203] (2) Relative time information, which is information about the time when the terminal records the report content of the SON and / or MDT-related report relative to a reference time. The reference time is the time when the configuration information corresponding to the SON and / or MDT-related report is received, or the time indicated by the absolute time information carried in the configuration information corresponding to the SON and / or MDT-related report, or the time when the SON and / or MDT-related report is sent.

[0204] Reporting the time information of the terminal recording the report content of the SON and / or MDT related report in the form of relative time information is beneficial to saving signaling overhead.

[0205] In some implementations, for SON and / or MDT related reports configured by the network, such as SHR or SPR, the terminal may use the time when the terminal receives the configuration information as a reference time and report the relative time information between the time(s) at which the report content is recorded and the reference time.

[0206] In some implementations, the configuration information for SON and / or MDT-related reports may carry absolute time information. The time indicated by the absolute time information is a reference time, and the terminal reports the relative time information between the time(s) at which the report content is recorded and the reference time. The terminal may also simultaneously report the absolute time information delivered in the configuration information.

[0207] In some implementations, when a terminal reports a SON and / or MDT-related report, the signaling reported by the terminal includes the relative time between the time(s) at which the terminal records the report content and the time at which the SON and / or MDT-related report is sent. The time at which the SON and / or MDT-related report is sent serves as a reference time. Upon receiving the relative time information reported by the terminal, the network can reversely infer the absolute time of the time(s) at which the terminal records the report content.

[0208] The flexibility of time information reporting is improved through multiple optional reporting methods of time information.

[0209] Figure 4 The second flow chart of the information reporting method provided in the embodiment of the present application is applied to a network device (eg, a base station), such as Figure 4 As shown, the method includes the following steps:

[0210] Step 400: When a non-terrestrial network (NTN) cell broadcasts multiple tracking areas (TAs), a self-organizing network and / or minimization of drive tests (SON) and / or MDT related report for the NTN cell sent by a terminal is received, where the SON and / or MDT related report includes information of a first TA or information of multiple second TAs.

[0211] Specifically, in the present application, for an NTN cell that broadcasts multiple TAs, when the terminal reports the SON and / or MDT-related report related to the NTN cell, the information of a first TA or information of multiple second TAs may be carried in the SON and / or MDT-related report. The first TA or multiple second TAs are used to indicate the TA range where the terminal is located. The network side may determine the single TA where the terminal is located based on the information of the first TA or the information of the multiple second TAs, or narrow the TA range as much as possible when determining the TA where the terminal is located.

[0212] Broadcasting multiple TAs refers to broadcasting multiple TAs for one cell (corresponding to one cell identity).

[0213] In some implementations, broadcasting multiple TAs may be broadcasting a TA list, where the TA list includes multiple TAs.

[0214] In this application, SON and / or MDT-related reports may include various reports related to SON and / or MDT, which are not specifically limited in this application. For example, SON and / or MDT-related reports may include: RLF or HOF reports, CEF reports, MHI reports, RACH reports, SHR, SPR, Logged MDT reports, Immediate MDT reports, etc.

[0215] This application does not limit the specific TAs referred to by the first TA and the second TA, as long as they can be used to indicate the TA range where the terminal is located to the network side.

[0216] The information reporting method provided by the embodiments of this application is applicable to the scenario where an NTN cell broadcasts multiple TAs. When reporting SON and / or MDT-related reports, the terminal can carry the information of a first TA or the information of multiple second TAs, enabling the network side to determine the single TA where the terminal is located based on the information of the first TA or multiple second TAs, or to narrow down the TA range as much as possible when determining the TA where the terminal is located, thereby facilitating subsequent network optimization or big data analysis.

[0217] In some embodiments, the first TA can be any one of the following:

[0218] (1) The TA where the terminal is located derived by the terminal based on the terminal's geographical location.

[0219] For example, if the terminal can derive the single TA where it is located based on its own geographical location, the terminal can report the information of this TA, such as TAI, in the SON and / or MDT-related report. The network side can determine the TA where the terminal is located according to the information of this TA.

[0220] It can be understood that the TA where the terminal is located derived by the terminal based on its own geographical location is one of the multiple TAs broadcast by the NTN cell.

[0221] In some embodiments, the terminal can report the geographical location information of the terminal to the network side, and the network side can map the geographical location information of the terminal to obtain the TA where the terminal is actually located when executing the record report content.

[0222] (2) A specific TA in the TA list broadcast by the NTN cell. Which specific TA in the TA list is not limited in this application, as long as the terminal and the network side have a consistent understanding of this specific TA.

[0223] For example, the specific TA can be the first TA, the last TA, or the TA in the middle in the TA list, etc.

[0224] The network side can determine which TA list the specific TA belongs to based on this specific TA, and then determine the single TA where the terminal is located from this TA list based on other information, or further narrow down the TA range based on this TA list.

[0225] (3) A specific TA among the multiple TAs that the terminal can access. Which specific TA among the TAs that the terminal can access is not limited in this application, as long as the terminal and the network side have a consistent understanding of this specific TA. For example, the specific TA can be the first TA in the TA list that the terminal can access.

[0226] The network side can determine which terminal - accessible TA list the specific TA belongs to based on the specific TA, and then determine the single TA where the terminal is located from the terminal - accessible TA list based on other information, or further narrow down the TA scope based on the terminal - accessible TA list. The terminal and the network side can determine the terminal - accessible TA list in the same way to ensure consistent understanding of the terminal - accessible TA list.

[0227] For example, the terminal can determine the intersection of the TA list broadcast by the network received by the AS layer of the terminal and the TAI list received by the NAS layer of the terminal from processes such as mobile registration update, and use the TAs in this intersection as the terminal - accessible TAs.

[0228] Alternatively, the terminal can exclude the TAs prohibited for the terminal to access from the list of Forbidden Tracking Areas obtained from the NAS layer of the terminal in the TA list broadcast by the network received by the AS layer of the terminal, and use the remaining TAs after excluding the prohibited - access TAs as the terminal - accessible TAs.

[0229] Alternatively, the terminal can use both the TAs in the above - mentioned intersection and the remaining TAs after excluding the prohibited - access TAs as the terminal - accessible TAs.

[0230] In some embodiments, the list of forbidden tracking areas includes: 5GS forbidden tracking areas for roaming in the 5G network, and / or 5GS forbidden tracking areas for regional provision of service in the 5G network.

[0231] (4) The only TA accessible to the terminal.

[0232] For example, for the case where there is only one terminal - accessible TA, the terminal can report the information of this one terminal - accessible TA in the SON - and / or MDT - related reports, and the network side can determine the TA where the terminal is located based on the information of this TA.

[0233] By reporting the information of a single TA, signaling overhead can be saved, and at the same time, the multiple alternative schemes of the first TA also improve the flexibility of TA information reporting.

[0234] In some embodiments, the multiple second TAs are any one of the following:

[0235] (1) All TAs in the TA list broadcast by the NTN cell.

[0236] In this case, the network side can determine a single TA where the terminal is located from these TAs reported by the terminal based on other information, or further narrow down the TA range based on these TAs reported by the terminal.

[0237] (2) Multiple TAs that the terminal can access.

[0238] For the multiple TAs that the terminal can access, refer to the previous description of the TAs that the terminal can access (or the list of TAs that the terminal can access), which will not be elaborated here.

[0239] In some embodiments, the TAs that the terminal can access include:

[0240] The intersection of the TA list broadcast by the NTN cell and the TA list received by the NAS layer of the terminal; and / or, other TAs in the TA list broadcast by the NTN cell except for the TAs that prohibit the terminal from accessing.

[0241] For example, the terminal can determine the intersection of the TA list broadcast by the network received by the AS layer of the terminal and the TAI list received by the NAS layer of the terminal from processes such as mobile registration update, and use the TAs in this intersection as the TAs that the terminal can access; or, the terminal can exclude the TAs that prohibit the terminal from accessing in the prohibited tracking area list obtained from the NAS layer of the terminal from the TA list broadcast by the network received by the AS layer of the terminal, and use the remaining TAs after excluding the prohibited access TAs as the TAs that the terminal can access; or, the terminal can use the TAs in the above intersection and the remaining TAs after excluding the prohibited access TAs as the TAs that the terminal can access together.

[0242] By reporting multiple second TAs instead of a specific TA, the subsequent processing operations on the network side can be reduced, the complexity of the network side processing is lowered, and it helps the network side to more accurately determine the TA range where the terminal is located, improving the accuracy of subsequent network optimization or big data analysis.

[0243] In some embodiments, the SON and / or MDT-related reports also contain the quantity information of multiple TAs broadcast by the NTN cell, that is, the terminal also reports the quantity of TAs broadcast by the NTN cell, which provides more auxiliary information for the network side to judge the TA range where the terminal is located, enabling the network side to more accurately judge the TA range where the terminal is located.

[0244] In some embodiments, when the terminal reports a specific TA in the TA list broadcast by the NTN cell, it can also report the quantity of TAs in this TA list to help the network side more accurately determine which TA list this specific TA belongs to.

[0245] In some embodiments, receiving the SON and / or MDT-related reports sent by the terminal for the NTN cell includes:

[0246] A SON and / or MDT related report for an NTN cell is received from a terminal through a first message, where the first message includes time information when the terminal records the report content of the SON and / or MDT related report.

[0247] For example, the terminal may carry the time information in which the terminal records the report content of the SON and / or MDT related report in the SON and / or MDT related report, or the terminal may report the time information together with the SON and / or MDT related report through the first message in addition to the SON and / or MDT related report.

[0248] The time information of the terminal's reporting of the contents of the SON and / or MDT-related reports can assist subsequent network-side nodes in performing specific analysis of the information at the corresponding time when receiving the terminal's SON and / or MDT-related reports. For example, the terminal can use the ephemeris information corresponding to the recorded time and the geographical location information reported by the terminal to determine the cell in which the terminal was located at that time, its position within the cell, its actual TA, and its position within the actual TA.

[0249] By reporting the time information of the terminal recording the report content of the SON and / or MDT-related report, the network side can understand the exact time when the terminal records the report content of the SON and / or MDT-related report, so that a more comprehensive analysis can be performed in combination with other information at the corresponding time, thereby improving the accuracy of the network side in determining the TA range where the terminal is located.

[0250] In some embodiments, the time information includes:

[0251] (1) Absolute time information, which is the absolute time when the terminal records the report content of the SON and / or MDT related report. The specific time format of the absolute time information is not limited in this application. For example, it can be an absolute time in GPS time format, an absolute time in UTC time format, etc.

[0252] Reporting the time information of the terminal recording the report content of the SON and / or MDT related report in the form of absolute time information can reduce subsequent processing operations on the network side and reduce the complexity of network side processing.

[0253] (2) Relative time information, which is information about the time when the terminal records the report content of the SON and / or MDT-related report relative to a reference time. The reference time is the time when the configuration information corresponding to the SON and / or MDT-related report is received, or the time indicated by the absolute time information carried in the configuration information corresponding to the SON and / or MDT-related report, or the time when the SON and / or MDT-related report is sent.

[0254] Reporting the time information of the report content of the terminal-recorded SON and / or MDT-related reports in the form of relative time information helps save signaling overhead.

[0255] In some embodiments, for SON and / or MDT-related reports with network configuration, such as SHR or SPR, etc., the terminal may use the moment when the terminal receives the configuration information as the reference moment, and report the relative time information between the (each) moment when the report content is recorded and this reference moment.

[0256] In some embodiments, an absolute time information may be carried in the configuration information of the SON and / or MDT-related reports. The moment indicated by this absolute time information is the reference moment, and the terminal reports the relative time information between the (each) moment when the report content is recorded and this reference moment. The terminal may also report the absolute time information sent in the configuration information at the same time.

[0257] In some embodiments, when the terminal reports SON and / or MDT-related reports, in the signaling reported by the terminal, the relative time between the (each) moment when the terminal records the report content and the moment when the SON and / or MDT-related reports are sent is carried, and the moment when the SON and / or MDT-related reports are sent is used as the reference moment. After the network side receives the relative time information reported by the terminal subsequently, it can inversely infer the absolute time of the (each) moment when the terminal records the report content.

[0258] Through various optional reporting methods of time information, the flexibility of time information reporting is improved.

[0259] In some embodiments, the method further includes:

[0260] Determining TA enhancement information based on one or more of SON and / or MDT-related reports, the time information of the report content of the terminal-recorded SON and / or MDT-related reports, the geographical location information of the terminal, and ephemeris information;

[0261] Sending any one of the following to other network devices or data collection nodes:

[0262] SON and / or MDT-related reports for NTN cells modified based on TA enhancement information; or,

[0263] SON and / or MDT-related reports, and TA enhancement information.

[0264] In some embodiments, other network devices may be other network-side nodes that perform parameter or configuration information optimization.

[0265] In some embodiments, the data collection node may be the operator's Trace Collection Entity (TCE).

[0266] After the network device receives the SON and / or MDT related report reported by the terminal, it can enhance the TA information based on the TA information carried in the SON and / or MDT related report, in combination with the time information of the report content recorded by the terminal for the SON and / or MDT related report, the geographical location information of the terminal, the ephemeris information, etc., to obtain TA enhanced information. This TA enhanced information is also used to indicate the TA range where the terminal is located, but after enhancement, it is more accurate than the TA information carried in the SON and / or MDT related report or further narrows the TA range.

[0267] In some embodiments, for the case where the terminal carries the geographical location information of the terminal in the SON and / or MDT related report, the network device can map the TA where the terminal is actually located when the report is recorded according to the geographical location information of the terminal, and use the information of this TA as the TA enhanced information.

[0268] In some embodiments, when the terminal does not carry the geographical location information of the terminal in the SON and / or MDT related report, or the network device does not support the function of calculating TA according to the geographical location information, the network device cannot directly map the TA where the terminal is actually located when the report is recorded according to the geographical location information of the terminal. Then, it can narrow the TA range or determine a single TA according to the time information of the reported record report content in combination with the ephemeris information known on the network side, etc., and use the TA information with the narrowed range or the information of this single TA as the TA enhanced information.

[0269] Then, there are two different ways to send the enhanced SON and / or MDT related report to other network devices or data collection nodes:

[0270] Method 1: Directly modify the TA related content in the "SON and / or MDT related report reported by the terminal" based on the TA enhanced information, and send the modified SON and / or MDT related report to other network devices or data collection nodes. This method can reduce the processing complexity of other network devices or data collection nodes after receiving the SON and / or MDT related report and reduce the signaling overhead.

[0271] Method 2: Do not modify the "SON and / or MDT related report reported by the terminal", but send the "SON and / or MDT related report reported by the terminal" and the TA enhanced information to other network devices or data collection nodes together. This method can reduce the processing complexity of the network device that sends the SON and / or MDT related report.

[0272] Enhancing TA information for SON and / or MDT related reports reported by the terminal and then sending it to other network devices or data collection nodes helps improve the accuracy of subsequent network optimization or big data analysis.

[0273] The methods provided in the embodiments of the present application are based on the same inventive concept. Therefore, the implementation of each method can be referred to each other, and the repeated parts will not be elaborated.

[0274] The following uses examples of specific application scenarios to illustrate the methods provided in the above embodiments of the present application.

[0275] Example 1: Enhancing TA for cell records reported over the air interface for SON or MDT purposes.

[0276] Due to satellite movement, the cells and TAs covering different geographical locations at different times may be different. At different times, the ground areas covered by NTN cells are also different. Therefore, for different times, NTN cells may broadcast different TAs or a list of multiple TAs.

[0277] If the NTN cell broadcasts a single TA (trackingAreaCode), the UE's processing method is the same as that for TN cells, that is, when the UE reports SON and / or MDT related reports, in the new radio (NR) cell information of the CGI-Info-Logging (Cell Global Identity Information Record) structure carried therein, the unique TAC information corresponding to the cell identity in the System Information Block (SIB) 1 broadcast is carried.

[0278] If the NTN cell broadcasts a TA list (trackingAreaList), the UE needs to enhance the SON / MDT reporting for this content. The enhancement methods can be:

[0279] (1) Directly report all the broadcast TAs (TA list corresponding to the cell identity).

[0280] In this method, the UE directly records the TA list in the SIB1 broadcast of the cell information corresponding to the moment when the UE records the report content. After the network side receives this TA list, it can analyze the ground location area covered by the satellite at the moment when the report content is recorded based on this. Or in combination with the possible geographical location information reported by the UE, determine the actual TA where the UE is located.

[0281] (2) Multiple TAs, which can be "UE accessible TAs":

[0282] a. The UE determines based on the intersection of the TA list broadcast by the network received by the UE AS layer and the TAI list received by the UE NAS layer during processes such as mobile registration updates; and / or,

[0283] b. Among the TA list broadcast by the network received by the UE AS layer, exclude the TAs that the UE is prohibited from accessing in the Forbidden Tracking Area list obtained from the UE NAS layer. The final TA information that the UE can access is obtained. The Forbidden Tracking Area list may include "5GS forbidden tracking areas for roaming" and / or "5GS forbidden tracking areas for regional provision of service".

[0284] In this method, the UE can further use the saved NAS information to narrow down the range of accessible TAs.

[0285] (3) A single TA, which can be:

[0286] a. The TA derived by the UE based on its own geographical location, and this TA is within the range of the TA list broadcast by the cell.

[0287] b. A specific TA in the TA list broadcast by the cell, such as the first TA, the last TA, or the TA in the middle. For example, in the case of fixed TA clustering, the first TA can be used as an index. The UE can also report the number of TAs broadcast by the cell.

[0288] c. The first TA that the UE can access, and this TA is the first TA in the above (2);

[0289] d. In the case where there is only a single TA among the TAs that the UE can access in the above (2), that is, a single accessible TA.

[0290] Example 2: Enhance the cell record time information reported over the air interface for SON or MDT purposes.

[0291] Due to satellite movement, the cells and TAs covering different geographical locations at different times may be different. Therefore, for the report content recorded by the UE, it is necessary to record the corresponding time information simultaneously, which can assist the subsequent network-side nodes in specifically analyzing the information corresponding to the corresponding time when receiving the SON and / or MDT-related reports from the UE. For example, using the ephemeris information corresponding to the time when the UE records the report content, the geographical location information reported by the UE, etc., to determine the cell where the UE is located at that time, the location within the cell, the actual TA, the location within the actual TA, etc.

[0292] The moments when the UE records the report content may include (exemplarily):

[0293] a. The moment when the UE records the HOF report or the RLF report.

[0294] b. The moment when the UE records the CEF report (each entry).

[0295] c. The moment when the UE records the RACH report (each entry).

[0296] d. The moment when the UE records the SHR or SPR.

[0297] e. The moment when the UE records the MHI report (each entry).

[0298] In the SON and / or MDT related reports of the UE, the way to carry time information can be:

[0299] (1) Absolute time information.

[0300] The absolute time information of the moment when the UE records the report content, such as GPS time information, UTC time information, etc.

[0301] (2) Relative time information.

[0302] Method 1: For SON and / or MDT related reports with network configuration, such as SHR or SPR, etc., taking the moment when the UE receives the configuration information as the reference moment, the configuration information may or may not carry absolute time information (this time information can be in the format of year / month / day / hour / minute / second). In the UE report, the relative time of the moment when the UE records the report content (each) relative to the reference moment is reported, or the absolute time information sent in the possible configuration information is also reported simultaneously.

[0303] Method 2: In the signaling of the UE reporting SON and / or MDT related reports, the relative time information of the moment when the UE records the report content (each) relative to the time when the UE sends the report is carried. After the network side receives the relative time information reported by the UE, the absolute time of the moment when the UE records the report content (each) can be inferred reversely.

[0304] Example 3: The interface transfers enhanced cell records for SON or MDT purposes.

[0305] In the UE reporting information of SON or MDT, it may or may not include the UE geographical location information. In the information reported by the base station of the NTN system itself to the core network, a separate TAI mapped according to the UE geographical location information can be reported.

[0306] After each UE report for SON or MDT purpose is sent from the UE to the base station, the base station will send the content reported by the UE to the node performing optimization according to the cell information in the report information.

[0307] In the case where the UE carries the UE geographic location information in the SON and / or MDT related reports, the base station can map the UE geographic location information to obtain the TA where the UE is actually located when the record is executed. If the UE does not carry the UE geographic location information in the SON and / or MDT related reports, or the base station does not support the function of calculating the TA based on the geographic location information, the base station cannot directly obtain the TA where the UE is actually located when the record is executed based on the UE geographic location information mapping. The TA range can be narrowed down or a single TA can be determined based on the time information carried in the UE reporting information combined with the ephemeris information known to the network side, and the TA enhancement information of the narrowed range can be sent to the node performing the optimization. The optimized sending method can be:

[0308] a. Directly modify the TA-related content in the "SON and / or MDT-related reports reported by the UE" based on the TA enhancement information and carry it on the inter-node interface signaling. This method only affects the organization behavior of inter-node messages and does not enhance the signaling itself.
