Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information recording and reporting method, device, apparatus and storage medium. Background Technology

[0002] To enable access to a primary cell (PCell) with good signal quality during Conditional Handover (CHO), while simultaneously accessing a primary cell (PSCell) within a secondary cell group (SCG), the 3rd Generation Partnership Project (3GPP) introduced Conditional Handover with Candidate SCG(s). This involves configuring one or more Conditional PSCell Addition / Change (CPAC) candidate cells (PSCells) for each CHO candidate cell (PCell), and configuring execution conditions for each PCell and PSCell. When the terminal (or User Equipment, UE) evaluates that both the CHO execution conditions and the CPAC execution conditions are met, the UE will execute CHO with candidate SCG(s).

[0003] There is no clear technical solution for how to record and report information in the event of a failure or critical failure for a UE configured with CHO with candidate SCG(s), which makes it impossible for the network to optimize the CHO with candidate SCG(s) configuration.

[0096] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0097] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0098] In the embodiments of this application, the terms "first," "second," etc., are used to distinguish similar objects, and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, and the number of objects is not limited; for example, the first object can be one or more.

[0099] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0100] Figure 1 This is one of the flowcharts illustrating the information recording and reporting method provided in the embodiments of this application. The method is applied to a terminal, such as... Figure 1 As shown, the method includes the following steps 101 and 102.

[0101] Step 101: If the terminal stores the conditional handover configuration with conditional secondary cell group and a failure or critical failure occurs, record the first information in the first report and / or the first message.

[0102] Step 102: Send the first report and / or first message to the network device.

[0103] The first report includes one or more of the following: radio link failure report, successful handover report, and successful addition or change of primary cell in secondary cell group. The first message includes secondary cell group failure information message. The first message includes one or more of the following: CHO information; CPAC information; Information regarding the relationship between CHO information and CPAC information; Information on the fulfillment of execution conditions in the conditional handover configuration of conditional secondary cell groups; Identification information for conditional handover configuration of conditional auxiliary cell groups.

[0104] Specifically, the network can configure CHO with candidate SCG(s) configuration for the UE. In order to better assist the network in optimizing the CHO with candidate SCG(s) configuration, the UE that stores the CHO with candidate SCG(s) configuration can record information related to CHO with candidate SCG(s) in the first report and / or the first message when a failure or critical failure occurs, i.e., the first information.

[0105] The following is a brief introduction to the first report and the first message that record the first information.

[0106] Radio Link Failure (RLF) report: This report is used to record information related to radio link failure or handover failure on the Master Cell Group (MCG) side. This report is not reported immediately, and the UE can store it for 48 hours.

[0107] Successful Handover Report (SHR): This report records information related to successful handover (but critical failure) on the MCG side. This report is not reported immediately; the UE can store it for 48 hours.

[0108] Successful PSCell Addition or Change Report (SPR): This report records information related to successful PSCell additions or changes on the SCG side (but critical failures). This report is not submitted immediately; the UE can store it for 48 hours.

[0109] SCG Failure Information Message: This message is used to report information related to SCG-side radio link failures or PSCell addition or modification failures. This message is reported immediately.

[0110] For RLF report, SHR, and SPR, these three types of reports are not reported in real time. The UE can send an available indication message to the network device (e.g., the base station) when it has stored the report. For example, the UE can send an RLF report available indication message, an SHR available indication message, or an SPR available indication message to the network device. After receiving the available indication message from the UE, if the network device wants to obtain the report information, it can send a UE information request message to the UE. After receiving the UE information request message from the network device, the UE sends a UE information response message to the network device. The UE information response message carries the first information recorded by the UE.

[0111] For the secondary cell group failure information message, this message is reported immediately. The UE does not need to send an indication of availability to the network device. Instead, it sends this message directly to the network device when an SCG failure occurs. This message carries the first information recorded by the UE.

[0112] After receiving the first report and / or the first message mentioned above, the network device can obtain the first information recorded therein, thereby optimizing the CHO with candidate SCG(s) configuration in a targeted manner.

[0113] It should be noted that the aforementioned failures can refer to handover failures, radio link failures, etc. A critical failure refers to the successful execution of a CHO with candidate SCG(s), but a critical failure occurs. This critical failure could be, for example, T310 exceeding a configured threshold, T312 exceeding a configured threshold, T304 exceeding a configured threshold, or the time interval between the execution conditions of candidate PCell and candidate PSCell exceeding a configured threshold. T310, T312, and T304 are timers with different functions; for details, please refer to existing technical documentation, which will not be elaborated upon here.

[0114] In this application, CHO information may refer to information related to CHO candidate cells (or candidate PCells), and CPAC information may refer to information related to CPAC candidate cells (or candidate PSCells). For specific examples, please refer to the embodiments below.

[0115] The correlation information between CHO and CPAC information can include the relationship between CHO candidate cells and CPAC candidate cells. This correlation refers to the relationship between CHO candidate cells and CPAC candidate cells in the CHO with candidate SCG(s) configuration. For example, in CHO with candidate SCG(s), PCell 1 is configured with three candidate cells: PSCell 1, PSCell 2, and PSCell 3, as well as the execution conditions corresponding to each group of CHO candidate cells and CPAC candidate cells. In the CHO with candidate SCG(s) configuration, the CHO configuration and CPAC configuration are correlated. Therefore, to better assist the network in optimizing the CHO with candidate SCG(s) configuration, the UE can report the correlation information between CHO information and CPAC information to the network when reporting information.

[0116] The execution conditions in the CHO with candidate SCG(s) configuration include CHO execution conditions and CPAC execution conditions. The information on the fulfillment of the execution conditions in the CHO with candidate SCG(s) configuration refers to the relevant information on the fulfillment of the CHO execution conditions and CPAC execution conditions. For specific examples, please refer to the embodiments below.

[0117] A CHO with candidate SCG(s) configuration can contain multiple candidate configurations. Each candidate configuration includes an associated CHO configuration and a CPAC configuration. Each candidate configuration is assigned a configuration identifier (ID), which can also be called a configuration index. The identifier information of the CHO with candidate SCG(s) configuration in this application can refer to the configuration ID or configuration index of each candidate configuration in the CHO with candidate SCG(s) configuration.

[0118] The information recording and reporting method provided in this application embodiment allows the terminal to record information related to CHO with candidate SCG(s) (i.e., first information) in reports and / or messages such as RLF report, SHR, SPR, and SCGFailureInformation message when a failure or critical failure occurs, and send it to the network device. This allows the network device to better optimize the CHO with candidate SCG(s) configuration based on the first information reported by the UE, which is beneficial to improving the success rate of CHO with candidate SCG(s) and user experience.

[0119] In some embodiments, CHO information includes one or more of the following: (1) The community identifier of the CHO candidate community.

[0120] For example, the cell identifier can be a combination of frequency point and physical cell identifier (PCI), or a cell global identifier (CGI).

[0121] (2) Indication information used to indicate whether a cell is a candidate cell for CHO.

[0122] For example, the indication information can be 1 bit. For instance, if the indication information associated with a cell is 1, it means that the cell is a CHO candidate cell, and if the indication information is 0, it means that the cell is not a CHO candidate cell. Alternatively, if the indication information associated with a cell is 0, it means that the cell is a CHO candidate cell, and if the indication information is 1, it means that the cell is not a CHO candidate cell. This indication information can be carried in the measurement results of each neighboring cell.

[0123] (3) Measurement results of CHO candidate cells.

[0124] For example, the measurement results may include Layer 3 (L3) measurement results and / or Layer 1 (L1) measurement results.

[0125] For example, the measurement result can be a measurement result obtained based on a measurement configuration configured on the master node (MN) and / or a measurement result obtained based on a measurement configuration configured on the secondary node (SN).

[0126] For example, the measurement result can correspond to the reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), L1-RSRP, etc.

[0127] (4) Index of CHO candidate cells.

[0128] For example, the index may be the cell number (or index) in the CHO candidate cells configured in CHO with candidate SCG(s).

[0129] (5) CHO implementation conditions.

[0130] The CHO execution condition refers to the execution condition of the candidate PCell in the CHO with candidate SCG(s) configuration.

[0131] (6) The first event to be satisfied in the CHO execution conditions.

[0132] This event, which can be called a CHO event or CHO execution condition, can be used to determine whether a candidate PCell meets the CHO execution condition.

[0133] It should be noted that this information can be recorded separately for each CHO execution condition.

[0134] For example, if the network configures one event for a candidate PCell, then the event that is satisfied first is that event. If the network configures two events for a candidate PCell, then the event that is satisfied first among the two events is the event that is satisfied first.

[0135] (7) When the CHO execution condition includes two events, the time interval between the two events is satisfied.

[0136] This event, which can be called a CHO event or CHO execution condition, can be used to determine whether a candidate PCell meets the CHO execution condition.

[0137] It should be noted that this information can be recorded separately for each CHO execution condition.

[0138] For example, if the network configures two events for a candidate PCell, then the time interval refers to the time interval between the two events, and the unit of the time interval can be granular such as ms (milliseconds), s (seconds), min (minutes), h (hours).

[0139] By recording one or more of the above CHO information in the first report and / or the first message, the network can better optimize the CHO with candidate SCG(s) configuration, and the information reporting can also be more flexible.

[0140] In some embodiments, CPAC information includes one or more of the following: (1) Cell identifier of CPAC candidate cell.

[0141] For example, the cell identifier can be a combination of frequency point and PCI, or it can be CGI.

[0142] (2) Indication information used to indicate whether a cell is a CPAC candidate cell.

[0143] For example, the indication information can be 1 bit. For instance, if the indication information associated with a cell is 1, it means that the cell is a CPAC candidate cell, and if the indication information is 0, it means that the cell is not a CPAC candidate cell. Alternatively, if the indication information associated with a cell is 0, it means that the cell is a CPAC candidate cell, and if the indication information is 1, it means that the cell is not a CPAC candidate cell. This indication information can be carried in the measurement results of each neighboring cell.

[0144] (3) Measurement results of CPAC candidate cells.

[0145] For example, the measurement results may include L3 measurement results and / or L1 measurement results.

[0146] For example, the measurement result can be the measurement result obtained by the measurement configuration based on the MN configuration and / or the measurement result obtained by the measurement configuration based on the SN configuration.

[0147] For example, the measurement quantity corresponding to the measurement result can be RSRP, RSRQ, SINR, L1-RSRP, etc.

[0148] (4) Index of CPAC candidate cells.

[0149] For example, the index may be the cell number (or index) in the CPAC candidate cells configured in CHO with candidate SCG(s).

[0150] (5) CPAC execution conditions.

[0151] The CPAC execution condition refers to the execution condition of each candidate PSCell in the CHO with candidate SCG(s) configuration.

[0152] (6) The first event to be satisfied in the CPAC execution conditions.

[0153] This event, also known as the CPAC event or CPAC execution condition, can be used to determine whether a candidate PSCell meets the CPAC execution condition.

[0154] It should be noted that this information can be recorded separately for each CPAC execution condition.

[0155] For example, if the network configures one event for a candidate PSCell, then the event that is satisfied first is that event. If the network configures two events for a candidate PSCell, then the event that is satisfied first among the two events is the event that is satisfied first.

[0156] (7) When the CPAC execution conditions include two events, the time interval between the two events.

[0157] This event, also known as the CPAC event or CPAC execution condition, can be used to determine whether a candidate PSCell meets the CPAC execution condition.

[0158] It should be noted that this information can be recorded separately for each CPAC execution condition.

[0159] For example, if the network is configured with two events for a candidate PSCell, then the time interval refers to the time interval between the two events, and the unit of the time interval can be granular such as ms, s, min, h, etc.

[0160] By recording one or more of the above CPAC information in the first report and / or the first message, the network can better optimize the CHO with candidate SCG(s) configuration and the information reporting can be more flexible.

[0161] In some embodiments, the fulfillment information of the execution conditions in the conditional handover configuration of the conditional secondary cell group includes one or more of the following: (1) In the conditional handover configuration of the conditional auxiliary cell group, the first execution condition to be met is the CHO execution condition or the CPAC execution condition.

[0162] It should be noted that this information can be recorded separately for each group of candidate configurations in the CHO with candidate SCG(s) configuration (or each group of CHO configuration and CPAC configuration, each group of candidate PCell and candidate PSCell, or each entry).

[0163] For example, for a certain set of candidate configurations, the CHO execution conditions and CPAC execution conditions may be satisfied in a certain order. The UE can report the execution condition that is satisfied first to the network.

[0164] In some implementations, the execution condition that must be satisfied first can be represented by an enumeration type, such as ENUMERATED{CHO, CPAC}.

[0165] (2) The time interval between the CHO execution condition being met and the CPAC execution condition being met in the conditional handover configuration of the conditional auxiliary cell group.

[0166] The time interval between the CHO execution condition being met and the CPAC execution condition being met in the conditional handover configuration of the conditional secondary cell group.

[0167] It should be noted that this information can be recorded separately for each candidate configuration in the CHO with candidate SCG(s) configuration (or each CHO configuration and CPAC configuration, each candidate PCell and candidate PSCell, or each Entry).

[0168] For example, for a certain set of candidate configurations, the time interval can be the time interval from when the CHO execution condition is met to when the CPAC execution condition is met, or the time interval from when the CPAC execution condition is met to when the CHO execution condition is met. The unit of the time interval can be granularity such as ms, s, min, h, etc.

[0169] By recording the fulfillment of one or more of the above execution conditions in the first report and / or the first message, the network can better optimize the CHO with candidate SCG(s) configuration, and the information reporting can also be more flexible.

[0170] In some embodiments, the method of recording association information includes: The relationship information is recorded in a list in the first report and / or the first message; or,

[0171] In the first report and / or the first message, record the correlation information based on the measurement results of neighboring cells.

[0172] Specifically, there are various ways to record the above-mentioned relationship information. In some embodiments, a list can be introduced in the first report and / or the first message to record the relationship information.

[0173] In some embodiments, the association information can be recorded using the neighboring cell measurement results in the first report and / or the first message, that is, the existing neighboring cell measurement results are reused to record the association information.

[0174] The neighbor cell measurement results in this application can be measurement results obtained by measurement configuration based on MN configuration and / or measurement results obtained by measurement configuration based on SN configuration.

[0175] Recording the above-mentioned relationship information in multiple different ways can improve the flexibility of information recording.

[0176] In some embodiments, the association information is recorded in a list in the first report and / or the first message, including: The association information is recorded in the first report and / or first message using any of the following first lists: The first list contains multiple first entries, each containing a set of CHO information and CPAC information; or...

[0177] The first list contains multiple second entries, each containing multiple sets of CHO and CPAC information, with the multiple sets of CHO and CPAC information corresponding to the same CHO candidate cell; or...

[0178] The first list contains multiple third entries, each containing multiple sets of CHO information and CPAC information, with the multiple sets of CHO information and CPAC information corresponding to the same CPAC candidate cell.

[0179] Specifically, the first list can take many different forms. In some embodiments, the first list can contain multiple first entries, each first entry recording a set of CHO information and CPAC information. Each set of CHO information and CPAC information refers to an interrelated set of CHO information and a set of CPAC information. Therefore, the network device can determine the association between the CHO information and CPAC information based on the set of CHO information and CPAC information contained in each first entry.

[0180] Figure 2 One of the example diagrams of the first list provided for embodiments of this application, such as Figure 2As shown, the first list contains Entry1, Entry2 and Entry3. Each Entry contains a configuration identifier (ID), candidate PCell information (i.e. CHO information) and candidate PSCell information (i.e. CPAC information), indicating that the candidate PCell and candidate PSCell in the Entry are related to each other. The configuration identifier indicates the configuration identifier of the candidate PCell and candidate PSCell in the CHO withcandidate SCG(s) configuration corresponding to the related set of candidate PCells and candidate PSCells.

[0181] In some embodiments, the first list may contain multiple second entries. Each second entry can be used to record multiple sets of CHO information and CPAC information, which correspond to the same CHO candidate cell. That is, one entry contains information about one CHO candidate cell and information about multiple CPAC candidate cells associated with that CHO candidate cell. The network device can determine the association between the CHO information and the CPAC information based on the multiple sets of CHO information and CPAC information contained in each second entry.

[0182] Figure 3 The second example of the first list provided for embodiments of this application, as shown in Figure 2. Figure 3 As shown, the first list contains Entry1 and Entry2. Each Entry contains information about a candidate PCell (i.e., CHO information) and one or more sub-Entries. Each sub-Entry contains a configuration identifier and information about a candidate PSCell (i.e., CPAC information), indicating that the candidate PSCell in each sub-Entry is associated with the candidate PCell. The configuration identifier in each sub-Entry indicates the configuration identifier corresponding to the candidate PSCell in the sub-Entry and the candidate PCell in the CHO with candidate SCG(s) configuration.

[0183] In some embodiments, the first list may contain multiple third entries. Each third entry records multiple sets of CHO information and CPAC information, which correspond to the same CPAC candidate cell. That is, one entry contains information about one CPAC candidate cell and information about multiple CHO candidate cells associated with that CPAC candidate cell. The network device can determine the association between the CHO information and the CPAC information based on the multiple sets of CHO information and CPAC information contained in each third entry.

[0184] Figure 4 The third example of the first list provided for embodiments of this application, such as Figure 4As shown, the first list contains Entry1 and Entry2. Each Entry contains information about a candidate PSCell (i.e., CPAC information) and one or more sub-Entries. Each sub-Entry contains a configuration identifier and information about a candidate PCell (i.e., CHO information), indicating that the candidate PCell in each sub-Entry is associated with the candidate PSCell. The configuration identifier in each sub-Entry indicates the configuration identifier corresponding to the candidate PCell in the sub-Entry and the candidate PSCell in the CHO with candidate SCG(s) configuration.

[0185] By recording one or more sets of related CHO and CPAC information for each entry in the first list, the relationship between CHO and CPAC information is implicitly indicated, thus saving signaling overhead.

[0186] In some embodiments, correlation information is recorded in the first report and / or first message based on neighboring cell measurement results, including: In the measurement results of each neighboring cell, record the CHO information of the neighboring cell as a CHO candidate cell, and at least one set of CPAC information associated with the CHO information; or,

[0187] In the measurement results of each neighboring cell, record the CPAC information of the neighboring cell as a CPAC candidate cell, as well as at least one set of CHO information associated with the CPAC information.

[0188] Specifically, there are several different ways to record the aforementioned correlation information in the neighboring cell measurement results. In some embodiments, the CHO information of each neighboring cell as a CHO candidate cell can be recorded in the measurement results of each neighboring cell, and at least one set of CPAC information associated with that CHO information can be recorded accordingly, such as... Figure 5 The diagram shown is an example of the neighbor cell measurement results. The neighbor cell measurement results include the measurement results of neighbor cell 1 and neighbor cell 2. Taking the measurement results of neighbor cell 1 as an example, the measurement results record the information of neighbor cell 1 (as a candidate PCell) and multiple sub-entries. Each sub-entry contains a configuration identifier and the information of the candidate PSCell (i.e., CPAC information), indicating that the candidate PSCell in each sub-entry is associated with the candidate PCell. The configuration identifier in each sub-entry indicates the configuration identifier corresponding to the candidate PSCell and the candidate PCell in the CHO with candidate SCG(s) configuration.

[0189] In some embodiments, the CPAC information of each neighboring cell as a CPAC candidate cell can be recorded in the measurement results of each neighboring cell, and at least one set of CHO information associated with the CPAC information can be recorded accordingly, such as... Figure 6 The diagram shown is an example of the neighbor cell measurement results. The neighbor cell measurement results include the measurement results of neighbor cell 1 and neighbor cell 2. Taking the measurement results of neighbor cell 2 as an example, the measurement results record the information of neighbor cell 2 (as a candidate PSCell) and multiple sub-entries. Each sub-entry contains a configuration identifier and the information of the candidate PCell (i.e., CHO information), indicating that the candidate PCell in each sub-entry is associated with the candidate PSCell. The configuration identifier in each sub-entry indicates the configuration identifier corresponding to the candidate PCell in the sub-entry and the candidate PSCell in the CHO with candidate SCG(s) configuration.

[0190] By recording the correlation information between CHO information and CPAC information through the above scheme, not only is the information recording method more flexible, but the reuse of existing neighbor cell measurement results can also reduce the complexity of signaling design.

[0191] In some embodiments, the association information is recorded in a list in the first report and / or the first message, including: Record the number association between CHO candidate cells and CPAC candidate cells in the second list of the first report and / or the first message, and record CHO information and / or CPAC information in the neighboring cell measurement results.

[0192] Specifically, the above-mentioned relationship information is recorded in a list in the first report and / or the first message. Alternatively, the relationship between the numbers of CHO candidate cells and CPAC candidate cells can be recorded in a second list. That is, the relationship between CHO candidate cells and CPAC candidate cells is represented by the relationship between cell numbers. The cell number can be represented by an introduced number value, or it can be represented by an existing cell index or cell identifier (such as PCI). There are no limitations on this.

[0193] When the number association between CHO candidate cells and CPAC candidate cells is recorded in the second list, CHO information and / or CPAC information can be recorded in the neighboring cell measurement results, which may include cell number information.

[0194] Figure 7 This is the third example diagram of the neighboring cell measurement results provided in the embodiments of this application, as shown in Figure 3. Figure 7As shown, the neighbor cell measurement results include the measurement results of neighbor cell 1, neighbor cell 2 and neighbor cell 3. The measurement results of each neighbor cell record the information of the neighbor cell as a candidate PCell (i.e., CHO information) and the information of the neighbor cell as a candidate PSCell (i.e., CPAC information).

[0195] Figure 8 Example diagram of the second list provided for embodiments of this application, such as Figure 8 As shown, the second list contains multiple Entries, each containing an index of a candidate PCell and an index of a candidate PSCell, indicating that the candidate PCell and the candidate PSCell are related. In addition, each Entry in the second list may also contain the respective execution conditions of the candidate PCell and the candidate PSCell.

[0196] The second list records the numbering relationship between CHO candidate cells and CPAC candidate cells, making the relationship between CHO information and CPAC information clearer and improving the flexibility of information reporting.

[0197] Figure 9 This is a second flowchart illustrating the information recording and reporting method provided in this application embodiment. The method is applied to network devices (e.g., base stations). Figure 9 As shown, the method includes the following steps: Step 901: Receive a first report and / or a first message sent by the terminal, wherein the first report and / or the first message contains first information.

The first message includes secondary cell group failure information message. The first message includes one or more of the following: CHO information; CPAC information; Information regarding the relationship between CHO information and CPAC information; Information on the fulfillment of execution conditions in the conditional handover configuration of conditional secondary cell groups; Identification information for conditional handover configuration of conditional auxiliary cell groups.

[0201] In some embodiments, the fulfillment information of the execution conditions in the conditional handover configuration of the conditional secondary cell group includes one or more of the following: In the conditional handover configuration of the conditional secondary cell group, the first execution condition to be met is either the CHO execution condition or the CPAC execution condition; The time interval between the fulfillment of the CHO execution condition and the fulfillment of the CPAC execution condition in the conditional handover configuration of the conditional secondary cell group.

[0202] In some embodiments, the first report and / or the first message includes first information, including: The first report and / or the first message includes a list for recording relationship information; or...

[0203] The neighboring cell measurement results in the first report and / or the first message contain correlation information.

[0204] In some embodiments, the list includes any of the following first lists: The first list contains multiple first entries, each containing a set of CHO information and CPAC information; or...

[0205] The first list contains multiple second entries, each containing multiple sets of CHO and CPAC information, with the multiple sets of CHO and CPAC information corresponding to the same CHO candidate cell; or...

[0206] The first list contains multiple third entries, each containing multiple sets of CHO information and CPAC information, with the multiple sets of CHO information and CPAC information corresponding to the same CPAC candidate cell.

[0207] In some embodiments, the neighboring cell measurement results in the first report and / or the first message include correlation information, including: The measurement results for each neighboring cell include CHO information for the neighboring cell as a CHO candidate cell, and at least one set of CPAC information associated with the CHO information; or,

[0208] The measurement results for each neighboring cell include CPAC information for the neighboring cell as a CPAC candidate cell, and at least one set of CHO information associated with the CPAC information.

[0209] In some embodiments, the list includes a second list for recording the number association between CHO candidate cells and CPAC candidate cells, and the neighbor cell measurement results in the first report and / or the first message include CHO information and / or CPAC information.

[0210] The methods provided in the various embodiments of this application are based on the same technical concept, so the implementation of each method can be referred to each other, and repeated parts will not be described again.

[0211] The methods provided in the above embodiments of this application are illustrated by specific examples below.

[0212] Example 1: Introduce a first list to record the relationship between CHO information and CPAC information.

[0213] Step 1-1: The network configures the UE with CHO with candidate SCG(s). When the UE fails or is on the verge of failure, the UE records the first information.

[0214] Taking the CHO with candidate SCG(s) configuration configured by the network for the UE as an example, which includes three sets of candidate configurations (each set of candidate configurations includes interrelated CHO configurations and CPAC configurations), the candidate PCells of the first and second sets of candidate configurations are the same, while the candidate PSCells are different. The candidate PSCells of the second and third sets of candidate configurations are the same, while the candidate PCells are different. The specific recording method can be any of the following: Option 1 (1): Introduce a first list to record the relationship between CHO information and CPAC information. This list includes multiple entries, each of which can record a set of CHO information and CPAC information. Each set of CHO information and CPAC information is a set of CHO information and a set of CPAC information that are mutually related, such as... Figure 2 As shown.

[0215] Option 1 (2): Introduce a first list to record the association information between CHO information and CPAC information. This list includes multiple entries, each of which can record multiple sets of CHO information and CPAC information. These multiple sets of CHO information and CPAC information correspond to the same candidate PCell, such as... Figure 3 As shown.

[0216] Option 1 (3): Introduce a first list to record the association information between CHO information and CPAC information. This list includes multiple entries, and each entry can record multiple sets of CHO information and CPAC information. These multiple sets of CHO information and CPAC information correspond to the same candidate PSCell, such as... Figure 4 As shown.

[0217] Steps 1-2: The UE reports available indication information to the network, such as sending an RLF report, an SHR report, or an SPR report to the network.

[0218] Steps 1-3: After receiving the available indication information from the UE, if the network wants to obtain report information for MRO, the network sends a UE information request message to the UE.

[0219] Steps 1-4: After receiving the UE information request message sent by the network, the UE sends a UE information response message to the network, which carries the first information recorded by the UE.

[0220] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the availability indication information to the network, but directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.

[0221] Example 2: Record the correlation information between CHO information and CPAC information in the measurement results of neighboring cells.

[0222] Step 2-1: The network configures the UE with CHO with candidate SCG(s) configuration. When the UE fails or is on the verge of failure, the UE records the first information.

[0223] Taking the CHO with candidate SCG(s) configuration configured by the network for the UE as an example, which includes three sets of candidate configurations (each set of candidate configurations includes interrelated CHO configurations and CPAC configurations), the candidate PCells of the first and second sets of candidate configurations are the same, while the candidate PSCells are different. The candidate PSCells of the second and third sets of candidate configurations are the same, while the candidate PCells are different. The specific recording method can be any of the following: Option 2 (1): Record the CHO information of each neighboring cell as a CHO candidate cell in the measurement results of each neighboring cell, and record at least one set of CPAC information associated with the CHO information, such as Figure 5 As shown.

[0224] Option 2 (2): Record the CPAC information of each neighboring cell as a CPAC candidate cell in the measurement results of each neighboring cell, and record at least one set of CHO information associated with the CPAC information, such as Figure 6 As shown.

[0225] Step 2-2: The UE reports the information that it can obtain to the network. For example, the UE can send an RLF report, an SHR report, or an SPR report to the network.

[0226] Steps 2-3: After receiving the available indication information from the UE, if the network wants to obtain report information for MRO, the network sends a UE information request message to the UE.

[0227] Steps 2-4: After receiving the UE information request message from the network, the UE sends a UE information response message to the network, which carries the first information recorded by the UE.

[0228] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the availability indication information to the network, but directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.

[0229] Recording CHO and CPAC information in the neighboring cell measurement results can refer to the legacy mechanism, which will not be elaborated here.

[0230] Example 3: Record CHO information and CPAC information in the measurement results of neighboring cells, and introduce a second list to record the correlation information between CHO information and CPAC information.

[0231] Step 3-1: The network configures the UE with CHO with candidate SCG(s) configuration. When the UE fails or is on the verge of failure, the UE records the first information.

[0232] Taking the CHO with candidate SCG(s) configuration configured by the network for the UE as an example, which includes three candidate configurations (each candidate configuration includes interrelated CHO configurations and CPAC configurations), the candidate PCells of the first and second candidate configurations are the same (index=0), but the candidate PSCells are different (the candidate PSCell of the first candidate configuration is index=0, and the candidate PSCell of the second candidate configuration is index=1). The candidate PSCells of the second and third candidate configurations are the same (index=1), but the candidate PCells are different (the candidate PCell of the second candidate configuration is index=0, and the candidate PCell of the third candidate configuration is index=1). The specific recording method is as follows: Option 3: Record CHO and CPAC information in the neighboring cell measurement results, number each candidate PCell and each candidate PSCell, and record the correspondence between the PCell and PSCell numbers in the imported second list, such as... Figure 7 and Figure 8 As shown.

[0233] Step 3-2: The UE reports the information that it can obtain to the network, such as sending an RLF report, an SHR report, or an SPR report.

[0234] Step 3-3: After receiving the available indication information from the UE, if the network wants to obtain report information for MRO, the network sends a UE information request message to the UE.

[0235] Steps 3-4: After receiving the UE information request message from the network, the UE sends a UE information response message to the network, which carries the first information recorded by the UE.

[0236] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the availability indication information to the network, but directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.
