[0079] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0080] In the embodiments of the present disclosure, the term "multiple" means two or more, and other quantifiers are similar.

[0081] The terms "first", "second", etc. in the embodiments of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" are generally a class and do not limit the number of objects, for example, the first object can be one or more.

[0082] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present disclosure.

[0083] FIG. 1 is a flowchart of an information recording and reporting method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 1, the method includes the following steps 101 and 102.

[0084] Step 101: In the case where the terminal stores a conditional handover configuration with a conditional secondary cell group and a failure or critical failure occurs, record first information in a first report and / or a first message.

[0085] Step 102: Send the first report and / or the first message to a network device.

[0086] The first report includes one or more of a radio link failure report, a successful handover report, a successful secondary cell group primary cell addition or change report, and the first message includes a secondary cell group failure information message. The first information includes one or more of the following:

[0087] CHO information;

[0088] CPAC information;

[0089] Association information of the CHO information and the CPAC information;

[0090] Information of execution of a condition in the conditional secondary cell group conditional handover configuration;

[0091] Identification information of the conditional secondary cell group conditional handover configuration.

[0092] In particular, the network can configure the UE with CHO with candidate SCG(s) configuration, in order to better assist the network to optimize the CHO with candidate SCG(s) configuration, the UE storing the CHO with candidate SCG(s) configuration can record the CHO with candidate SCG(s) related information, i.e. the first information, in the first report and / or the first message when failure or critical failure occurs.

[0093] The first report and the first message recording the first information are briefly introduced as follows.

[0094] Radio Link Failure (RLF) report: used to record the related information of Master Cell Group (MCG) side radio link failure or handover failure, this report is not reported immediately, and the UE can store it for 48 hours.

[0095] Successful Handover Report (SHR): used to record the related information of MCG side successful handover (but critical failure), this report is not reported immediately, and the UE can store it for 48 hours.

[0096] Successful PSCell Addition or Change Report (SPR): used to record the related information of SCG side successful PSCell addition or change (but critical failure), this report is not reported immediately, and the UE can store it for 48 hours.

[0097] SCGFailureInformation message: used to report the related information of SCG side radio link failure or PSCell addition or change failure, this message is reported immediately.

[0098] For RLF report, SHR, and SPR, the three reports are non-immediate reporting. The UE can send available indication information to the network device (e.g., base station) in the case of storing the report. For example, the UE can send RLF report available indication information or SHR available indication information or SPR available indication information to the network device. After the network device receives the available indication information sent by the UE, if the network device wants to obtain the report information, the network device can send a UE information request message to the UE. After the UE receives the UE information request message sent by 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.

[0099] For the secondary cell group failure information message, the message is immediate reporting. The UE does not need to send available indication information to the network device, but directly sends the message to the network device when SCG failure occurs. The message carries the first information recorded by the UE.

[0100] After the network device receives the above-mentioned first report and / or first message, the network device can obtain the first information recorded therein, thereby optimizing the CHO with candidate SCG(s) configuration in a targeted manner.

[0101] It should be noted that the above-mentioned failure can refer to handover failure, radio link failure, etc. Critical failure refers to successful execution of CHO with candidate SCG(s), but critical failure occurs. The critical failure may be, for example, that T310 exceeds a configured threshold, T312 exceeds a configured threshold, T304 exceeds a configured threshold, a time interval in which the execution conditions of the candidate PCell and the candidate PSCell are met exceeds a configured threshold, etc. T310, T312, and T304 are timers (Timers) with different functions. For details, please refer to existing technical materials, which will not be described here.

[0102] In the present disclosure, CHO information can refer to CHO candidate cell (or candidate PCell) related information, and CPAC information can refer to CPAC candidate cell (or candidate PSCell) related information. For specific examples, please refer to the embodiments described below.

[0103] The association information of the CHO information and the CPAC information can include an association between the CHO candidate cell and the CPAC candidate cell, and the association refers to an association between the CHO candidate cell and the CPAC candidate cell in the CHO with candidate SCG(s) configuration, for example, in the CHO with candidate SCG(s), the PCell 1 is configured with three candidate cells, i.e., the PSCell 1, the PSCell 2 and the PSCell 3, and each group of the CHO candidate cell and the CPAC candidate cell corresponds to an execution condition. In the CHO with candidate SCG(s) configuration, the CHO configuration and the CPAC configuration are associated, and therefore, in order to better assist the network in optimizing the CHO with candidate SCG(s) configuration, the UE can report the association information of the CHO information and the CPAC information to the network when reporting the information.

[0104] The execution condition in the CHO with candidate SCG(s) configuration includes a CHO execution condition and a CPAC execution condition, and the satisfaction information of the execution condition in the CHO with candidate SCG(s) configuration refers to related information of the satisfaction of the CHO execution condition and the CPAC execution condition, and specific examples can be referred to the embodiments below.

[0105] The CHO with candidate SCG(s) configuration can include multiple groups of candidate configurations, each group of candidate configurations includes an associated CHO configuration and a CPAC configuration, and each group of candidate configurations is assigned a configuration identifier (Identifier, ID), which can also be referred to as a configuration index (index), and the identifier information of the CHO with candidate SCG(s) configuration in the disclosure can refer to the configuration ID or the configuration index of each group of candidate configurations in the CHO with candidate SCG(s) configuration.

[0106] The information recording and reporting method provided by the embodiments of the present disclosure can record the information (i.e., first information) related to the CHO with candidate SCG(s) in the RLF report, SHR, SPR, SCGFailureInformation message, and / or the like and send it to the network device in the case that the terminal has the CHO with candidate SCG(s) configuration stored and failure or critical failure occurs, so that the network device can better optimize the CHO with candidate SCG(s) configuration according to the first information reported by the UE, and help to improve the success rate of the CHO with candidate SCG(s) and user experience.

[0107] In some embodiments, the CHO information includes one or more of the following:

[0108] (1) Cell identity of the CHO candidate cell.

[0109] For example, the cell identity can be a combination of a frequency and a physical cell identifier (PCI), or a cell global identifier (CGI).

[0110] (2) Indication information used to indicate whether a cell is a CHO candidate cell.

[0111] For example, the indication information can be 1-bit indication information, such as: the indication information associated with a certain cell takes a value of 1 to indicate that the cell is a CHO candidate cell, and the indication information takes a value of 0 to indicate that the cell is not a CHO candidate cell; or the indication information associated with a certain cell takes a value of 0 to indicate that the cell is a CHO candidate cell, and the indication information takes a value of 1 to indicate that the cell is not a CHO candidate cell. This indication information can be carried in each neighbor cell measurement result.

[0112] (3) Measurement result of the CHO candidate cell.

[0113] For example, the measurement result can include a Layer 3 (L3) measurement result and / or a Layer 1 (L1) measurement result.

[0114] For example, the measurement result can be a measurement result obtained based on a measurement configuration configured by a master node (MN) and / or a measurement result obtained based on a measurement configuration configured by a secondary node (SN).

[0115] Exemplarily, the measurement result corresponding to the measurement quantity can be Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), L1-RSRP, etc.

[0116] (4) Index of CHO candidate cell.

[0117] Exemplarily, the index can be the number (or index) of the cell in the CHO candidate cell in the CHO with candidate SCG(s) configuration.

[0118] (5) CHO execution condition.

[0119] The CHO execution condition refers to the execution condition of the candidate PCell in the CHO with candidate SCG(s) configuration.

[0120] (6) Event that is first satisfied in the CHO execution condition.

[0121] The event can be referred to as a CHO event or a CHO execution condition, and the event can be used to determine whether the candidate PCell satisfies the CHO execution condition.

[0122] It should be noted that this information can be recorded for each CHO execution condition respectively.

[0123] For example, if the network configures an event for a certain candidate PCell, the first satisfied event is this event, and if the network configures two events for a certain candidate PCell, the first satisfied event is the event that is first satisfied.

[0124] (7) Time interval in which two events are satisfied in the case where the CHO execution condition contains two events.

[0125] The event can be referred to as a CHO event or a CHO execution condition, and the event can be used to determine whether the candidate PCell satisfies the CHO execution condition.

[0126] It should be noted that this information can be recorded for each CHO execution condition respectively.

[0127] For example, if the network configures two events for a certain candidate PCell, the time interval refers to the time interval that the two events satisfy, and the unit of the time interval can be ms (millisecond), s (second), min (minute), h (hour), etc.

[0128] By recording one or more 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 be more flexible.

[0129] In some embodiments, the CPAC information includes one or more of the following:

[0130] (1) Cell identity of the CPAC candidate cell.

[0131] For example, the cell identity can be a combination of a frequency and a PCI, or a CGI.

[0132] (2) Indication information for indicating whether a cell is a CPAC candidate cell.

[0133] For example, the indication information can be 1-bit indication information, e.g., the indication information associated with a certain cell takes a value of 1 to indicate that the cell is a CPAC candidate cell, and the indication information takes a value of 0 to indicate that the cell is not a CPAC candidate cell; or the indication information associated with a certain cell takes a value of 0 to indicate that the cell is a CPAC candidate cell, and the indication information takes a value of 1 to indicate that the cell is not a CPAC candidate cell. This indication information can be carried in each neighbor cell measurement result.

[0134] (3) Measurement result of the CPAC candidate cell.

[0135] For example, the measurement result can include an L3 measurement result and / or an L1 measurement result.

[0136] For example, the measurement result can be a measurement result obtained based on a measurement configuration configured by the MN and / or a measurement result obtained based on a measurement configuration configured by the SN.

[0137] For example, the measurement quantity corresponding to the measurement result can be RSRP, RSRQ, SINR, L1-RSRP, etc.

[0138] (4) Index of the CPAC candidate cell.

[0139] For example, the index can be the number (or index) of the cell in the CPAC candidate cells of the CHO with candidate SCG(s) configuration.

[0140] (5) CPAC execution condition.

[0141] The CPAC execution condition refers to the execution condition of each candidate PSCell in the CHO with candidate SCG(s) configuration.

[0142] (6) The first satisfied event in the CPAC execution condition.

[0143] The event can be referred to as a CPAC event or a CPAC execution condition, and the event can be used to determine whether the candidate PSCell satisfies the CPAC execution condition.

[0144] It should be noted that this information can be recorded separately for each CPAC execution condition.

[0145] For example, if the network configures one event for a certain candidate PSCell, the first satisfied event is this event. If the network configures two events for a certain candidate PSCell, the first satisfied event is the first satisfied event of the two events.

[0146] (7) In the case where the CPAC execution condition contains two events, the time interval in which the two events are satisfied.

[0147] The event can be referred to as a CPAC event or a CPAC execution condition, and the event can be used to determine whether the candidate PSCell satisfies the CPAC execution condition.

[0148] It should be noted that this information can be recorded separately for each CPAC execution condition.

[0149] For example, if the network configures two events for a certain candidate PSCell, the time interval refers to the time interval in which the two events are satisfied, and the unit of the time interval can be ms, s, min, h, etc.

[0150] By recording one or more 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.

[0151] In some embodiments, the satisfaction information of the execution condition in the conditional secondary cell group conditional handover configuration includes one or more of the following:

[0152] (1) The first satisfied execution condition in the conditional secondary cell group conditional handover configuration is a CHO execution condition or a CPAC execution condition.

[0153] 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).

[0154] For example, for a certain candidate configuration, there can be a time sequence in which the CHO execution condition and the CPAC execution condition are met. The UE can report the execution condition that is first met to the network.

[0155] In some embodiments, the first met execution condition can be represented by an enumeration type, such as ENUMERATED{CHO, CPAC}.

[0156] (2) The time interval between the meeting of the CHO execution condition and the meeting of the CPAC execution condition in the conditional handover configuration with conditional secondary cell group.

[0157] The time interval between the meeting of the CHO execution condition and the meeting of the CPAC execution condition in the conditional handover configuration with conditional secondary cell group.

[0158] 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).

[0159] For example, for a certain candidate configuration, the time interval can be the time interval from the meeting of the CHO execution condition to the meeting of the CPAC execution condition, or the time interval from the meeting of the CPAC execution condition to the meeting of the CHO execution condition. The unit of the time interval can be ms, s, min, h, etc.

[0160] By recording the meeting information of one or more 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.

[0161] In some embodiments, the recording method of the association relationship information includes:

[0162] The association relationship information is recorded by a list in the first report and / or the first message; or,

[0163] The association relationship information is recorded by the neighbor cell measurement result in the first report and / or the first message.

[0164] Specifically, for the above-mentioned association relationship information, there can be multiple different recording manners. In some embodiments, a list can be introduced in the first report and / or the first message to record the association relationship information.

[0165] In some embodiments, the association relationship information can be recorded through the neighbor cell measurement result in the first report and / or the first message, i.e., the existing neighbor cell measurement result is reused to record the association relationship information.

[0166] The neighbor cell measurement result in the present disclosure can be a measurement result obtained based on a measurement configuration configured by the MN and / or a measurement result obtained based on a measurement configuration configured by the SN.

[0167] By recording the above-mentioned association relationship information in multiple different manners, the flexibility of information recording can be improved.

[0168] In some embodiments, the association relationship information is recorded in the first report and / or the first message through a list, including:

[0169] The association relationship information is recorded in the first report and / or the first message through any one of the following first lists:

Each set of CHO information and CPAC information refers to a set of CHO information and a set of CPAC information that are associated with each other. Therefore, the network device can determine the association relationship of the CHO information and the CPAC information according to the set of CHO information and CPAC information contained in each first entry.

The network device can determine the association relationship between the CHO information and the CPAC information according to the plurality of groups of CHO information and CPAC information included in each third entry.

[0178] FIG. 4 is a third example diagram of a first list according to an embodiment of the present disclosure. As shown in FIG. 4, the first list includes Entry 1 and Entry 2. Each Entry includes information of a candidate PSCell (i.e., CPAC information) and one or more sub-Entries. Each sub-Entry includes a configuration identifier and information of a candidate PCell (i.e., CHO information), indicating that the candidate PCell in each sub-Entry is associated with the candidate PSCell, and 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.

[0179] The CHO information and the CPAC information in each Entry of the first list are recorded respectively, and the association between the CHO information and the CPAC information is implicitly indicated, thereby saving signaling overhead.

[0180] In some embodiments, the association information is recorded in the first report and / or the first message by the measurement results of the neighbor cells, including:

[0181] The CHO information of the neighbor cell as a CHO candidate cell is recorded in the measurement result of the neighbor cell, and at least one set of CPAC information associated with the CHO information is recorded; or

[0182] The CPAC information of the neighbor cell as a CPAC candidate cell is recorded in the measurement result of the neighbor cell, and at least one set of CHO information associated with the CPAC information is recorded.

[0183] Specifically, the association information can be recorded in the measurement result of the neighbor cell in various ways. In some embodiments, the CHO information of the neighbor cell as a CHO candidate cell is recorded in the measurement result of the neighbor cell, and at least one set of CPAC information associated with the CHO information is recorded. As shown in FIG. 5, the measurement result of the neighbor cell includes the measurement result of neighbor cell 1 and the measurement result of neighbor cell 2. Taking the measurement result of neighbor cell 1 as an example, the measurement result of neighbor cell 1 includes information of the neighbor cell 1 (as a candidate PCell) and a plurality of sub-Entries. Each sub-Entry includes a configuration identifier and information of a candidate PSCell (i.e., CPAC information), indicating that the candidate PSCell in each sub-Entry is associated with the candidate PCell, and 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.

[0184] In some embodiments, the CPAC information of each neighbor cell as a CPAC candidate cell can be recorded in the measurement result of the neighbor cell, and at least one set of CHO information associated with the CPAC information can be recorded correspondingly. As shown in FIG. 6, an example of the measurement result of the neighbor cell is shown, which includes the measurement result of neighbor cell 1 and the measurement result of neighbor cell 2. Taking the measurement result of neighbor cell 2 as an example, the information of the neighbor cell 2 (as a candidate PSCell) and a plurality of sub-entries are recorded in the measurement result, each sub-entry including a configuration identifier and the information of a candidate PCell (i.e., CHO information), indicating that the candidate PCell in each sub-entry is associated with the candidate PSCell, and 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.

[0185] By recording the association relationship information of the CHO information and the CPAC information through the above scheme, the information recording method is more flexible, and the reuse of the existing neighbor cell measurement result can reduce the complexity of signaling design.

[0186] In some embodiments, the association relationship information is recorded in the first report and / or the first message through a list, including:

[0187] The number association relationship of the CHO candidate cell and the CPAC candidate cell is recorded in the second list of the first report and / or the first message, and the CHO information and / or the CPAC information is recorded in the neighbor cell measurement result.

[0188] Specifically, the association relationship information is recorded in the first report and / or the first message through a list, which can be the number association relationship of the CHO candidate cell and the CPAC candidate cell recorded through a second list, i.e., the association relationship of the CHO candidate cell and the CPAC candidate cell is represented by the association relationship of the cell numbers, which can be represented by introducing a number value, or can be represented by using the existing cell index or cell identifier (e.g., PCI), which is not limited here.

[0189] In the case of recording the number association relationship of the CHO candidate cell and the CPAC candidate cell through the second list, the CHO information and / or the CPAC information can be recorded in the neighbor cell measurement result, which can include the information of the cell number.

[0190] FIG. 7 is a third example diagram of neighbor cell measurement results according to an embodiment of the present disclosure. As shown in FIG. 7, the neighbor cell measurement results include measurement results of neighbor cell 1, measurement results of neighbor cell 2, and measurement results of neighbor cell 3. Each of the measurement results of the neighbor cells records information (i.e., CHO information) that the neighbor cell is a candidate PCell and information (i.e., CPAC information) that the neighbor cell is a candidate PSCell.

[0191] FIG. 8 is an example diagram of a second list according to an embodiment of the present disclosure. As shown in FIG. 8, the second list includes a plurality of Entries. Each of the Entries includes an index of a candidate PCell and an index of a candidate PSCell, indicating that the candidate PCell and the candidate PSCell are associated with each other. In addition, each of the Entries of the second list can further include execution conditions of the candidate PCell and the candidate PSCell, respectively.

[0192] By recording the association between the CHO candidate cell and the CPAC candidate cell in the second list, the association between the CHO information and the CPAC information is more explicit, and the flexibility of information reporting can be improved.

[0231] The methods provided by the embodiments of the present disclosure are based on the same technical concept, and therefore the implementation of each method can be referred to each other, and the repeated parts will not be described again.

[0232] The methods provided by the above-mentioned embodiments of the present disclosure are exemplified below through specific examples.

[0233] Example 1: Introducing a first list to record the association information of CHO information and CPAC information.

[0234] Step 1-1, the network configures the UE with CHO with candidate SCG(s) configuration, the UE occurs failure or critical failure, and the UE records the first information.

[0235] Take the network as an example of UE configured CHO with candidate SCG(s) configuration, which includes three groups of candidate configurations (each group of candidate configurations includes interrelated CHO configuration and CPAC configuration), wherein the candidate PCell of the first group of candidate configurations and the second group of candidate configurations is the same, the candidate PSCell is different, the candidate PSCell of the second group of candidate configurations and the third group of candidate configurations is the same, and the candidate PCell is different. The specific recording method can be any one of the following:

[0236] Scheme one (1): Introduce a first list to record the association relationship information of CHO information and CPAC information, which includes multiple entries in the list, and each entry can record a group of CHO information and CPAC information. Each group of CHO information and CPAC information is a set of interrelated CHO information and a set of CPAC information, as shown in FIG. 2.

[0237] Scheme one (2): Introduce a first list to record the association relationship information of CHO information and CPAC information, which includes multiple entries in the list, and each entry can record multiple groups of CHO information and CPAC information. The multiple groups of CHO information and CPAC information correspond to the same candidate PCell, as shown in FIG. 3.

[0238] Scheme one (3): Introduce a first list to record the association relationship information of CHO information and CPAC information, which includes multiple entries in the list, and each entry can record multiple groups of CHO information and CPAC information. The multiple groups of CHO information and CPAC information correspond to the same candidate PSCell, as shown in FIG. 4.

[0239] Step 1-2, the UE reports the available indication information to the network, such as the UE sending the RLF report available indication information or the SHR available indication information or the SPR available indication information to the network.

[0240] Step 1-3, after the network receives the available indication information sent by the UE, if it wants to obtain the report information for MRO, the network sends a UE information request message to the UE.

[0241] Step 1-4, after the UE receives 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.

[0242] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the available indication information to the network, but directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.

[0243] Example 2: record the association information of CHO information and CPAC information in the measurement result of neighbor cell.

[0244] Step 2-1, the network configures CHO with candidate SCG(s) configuration for the UE, the UE occurs failure or critical failure, and the UE records the first information.

[0245] The CHO with candidate SCG(s) configuration configured by the network for the UE includes three groups of candidate configurations (each group of candidate configurations includes associated CHO configuration and CPAC configuration), for example, the candidate PCell of the first group of candidate configurations and the second group of candidate configurations is the same, and the candidate PSCell is different, the candidate PSCell of the second group of candidate configurations and the third group of candidate configurations is the same, and the candidate PCell is different. The specific recording method can be any one of the following:

[0246] Scheme two (1): record the CHO information of the neighbor cell as a CHO candidate cell in the measurement result of each neighbor cell, and correspondingly record at least one set of CPAC information associated with the CHO information, as shown in FIG. 5.

[0247] Scheme two (2): record the CPAC information of the neighbor cell as a CPAC candidate cell in the measurement result of each neighbor cell, and correspondingly record at least one set of CHO information associated with the CPAC information, as shown in FIG. 6.

[0248] Step 2-2, the UE reports the available indication information to the network, such as the UE can send RLF report available indication information or SHR available indication information or SPR available indication information to the network.

[0249] Step 2-3, after the network receives the available indication information sent by the UE, if the network wants to obtain the report information for MRO, the network sends a UE information request message to the UE.

[0250] Step 2-4, after the UE receives 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.

[0251] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the available indication information to the network, and directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.

[0252] The record of CHO information and CPAC information in the measurement result of neighbor cell can refer to the legacy (legacy) mechanism, which will not be described here.

[0253] Example 3: record CHO information and CPAC information in the neighbor cell measurement result, introduce a second list to record the association information of CHO information and CPAC information.

[0254] Step 3-1, the network configures CHO with candidate SCG configuration for the UE, the UE occurs failure or critical failure, and the UE records the first information.

[0255] Take the CHO with candidate SCG configuration configured by the network for the UE as an example, which includes three groups of candidate configurations (each group of candidate configurations includes associated CHO configuration and CPAC configuration), wherein the candidate PCell of the first group of candidate configurations and the second group of candidate configurations is the same (numbered as index = 0), and the candidate PSCell is different (the candidate PSCell of the first group of candidate configurations is numbered as index = 0, and the candidate PSCell of the second group of candidate configurations is numbered as index = 1), the candidate PSCell of the second group of candidate configurations and the third group of candidate configurations is the same (numbered as index = 1), and the candidate PCell is different (the candidate PCell of the second group of candidate configurations is numbered as index = 0, and the candidate PCell of the third group of candidate configurations is numbered as index = 1). The specific recording method is as follows:

[0256] Scheme three: record CHO information and CPAC information in the neighbor cell measurement result, number each candidate PCell and each candidate PSCell, and record the number correspondence of PCell and PSCell in the introduced second list, as shown in FIG. 7 and FIG. 8.

[0257] Step 3-2, the UE reports the obtainable indication information to the network, such as the UE can send RLF report obtainable indication information or SHR obtainable indication information or SPR obtainable indication information to the network.

[0258] Step 3-3, after the network receives the obtainable indication information sent by the UE, if the network wants to obtain the report information for MRO, the network sends a UE information request message to the UE.

[0259] Step 3-4, after the UE receives 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.

[0260] It should be noted that if the UE records the first information in the SCGFailureInformation message, the UE does not need to send the available indication information to the network, but directly sends the SCGFailureInformation message to the network, which carries the first information recorded by the UE.

[0261] The index (or number) of the candidate PCell and the index (or number) of the candidate PSCell can be explicit or implicit, that is, a number value (such as the example above) can be introduced to show the representation, or the identification information (such as PCI) of the PCell and PSCell can be used to implicitly represent, that is, in the introduced second list, the recorded number value can be 0, 1, 2, …, or the cell identification information, which is not limited here.

[0262] Recording CHO information and CPAC information in the neighbor cell measurement result can refer to the legacy (traditional) mechanism, which is not described here.
