[0078] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 , wherein the network device includes at least one of the following: an access network device and a core network device.

[0079] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0080] In some embodiments, the access network device is, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0081] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0082] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0083] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0084] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0085] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0086] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0087] In some embodiments, when the terminal successfully performs a handover operation (eg, switching cells), it may send a successful handover report to the network device so that the network device can properly understand the network environment of the terminal and make appropriate configurations for the terminal.

[0088] In some embodiments, the SHR can record the measurement results of the terminal on the cell, but the measurement results do not include Layer 1 or Layer 2 triggered mobility (L1 / L2-Triggered Mobility, LTM) related information. For some scenarios, the SHR that does not record LTM related information is insufficient for the network equipment, and it is difficult to ensure that the network equipment properly understands the network environment of the terminal.

[0089] For example, in an LTM scenario, the network device can configure LTM configuration information for the terminal. The LTM configuration information includes LTM candidate cells (which can be a single cell or a cell group consisting of multiple cells) and related information used for communication in the candidate cells.

[0090] The network device can subsequently perform LTM cell switching on the terminal. For example, the network device can instruct the terminal to change the cell through layer 1 (for example, through downlink control information (DCI)) or layer 2 (for example, through a media access control layer control unit (MAC CE)), for example, instruct the terminal to change the cell from candidate cell #1 to candidate cell #2.

[0091] Since the relevant information used for communication in the candidate cell is pre-configured to the terminal by the network device through LTM configuration, after the terminal switches to candidate cell #2, the network device does not need to configure the relevant information used for communication in candidate cell #2 for the terminal, which is conducive to the terminal completing cell switching and communication as soon as possible.

[0092] L3-triggered mobility cell switching, such as traditional handover (HO) and conditional handover (CHO), is triggered by radio resource control (RRC) signaling. Compared with LTM cell switching, this takes longer and is not conducive to the terminal completing cell switching and communication as quickly as possible.

[0093] In the related art, the terminal can perform LTM cell switching based on the LTM configuration information configured by the network device and the switching command sent by the network device. However, the SHR in the related art does not include LTM-related information, and thus cannot be accurately used by the network device to determine the terminal's LTM-related situation. Therefore, it is necessary to improve the SHR sent by the terminal to the network device.

[0094] FIG2 is an interactive schematic diagram illustrating an information recording method according to an embodiment of the present disclosure.

[0095] In step S201, the terminal records LTM related information in the SHR.

[0096] In step S202, the terminal sends the SHR to the network device.

[0097] In some embodiments, the terminal receives request information sent by the network device, wherein the request information is used to request the terminal to send the SHR to the network device.

[0098] For example, the terminal may send the SHR containing LTM-related information to the network device only after receiving a request message from the network device. The request message may reuse a conventional request message (e.g., a request for obtaining an SHR), or may be a newly defined request message specifically for requesting the terminal to send the SHR containing LTM-related information.

[0099] It should be noted that, in some embodiments, the terminal may send LTM-related information to the network device not based on the request information of the network device. For example, the terminal may record the time t1 for determining the LTM-related information. When no request information from the network device is received within the time range from t1 to T1, the terminal may automatically send the LTM-related information (for example, on pre-configured resources) to the network device. This helps to avoid the terminal's LTM-related information being deleted during the storage time, resulting in waste of measurement operation overhead.

[0100] In an embodiment of the present disclosure, the terminal records LTM-related information in the SHR so that it can be sent to the network device later as needed or requested by the network device. Compared with the terminal only recording traditional switching mode related information in the SHR, the SHR recording LTM-related information can be used by the network device to accurately determine the terminal's LTM-related situation, which is beneficial to ensure that the network device can promptly and accurately determine whether to perform LTM based on the SHR reported by the terminal.

[0101] It should be noted that in some embodiments, the terminal may also record LTM-related information in a Radio Link Failure (RLF) report. For example, if LTM recovery is successful (RLF occurs during LTM handover, and another access attempt based on the LTM configuration is successful), the terminal may not perform the operation of recording LTM-related information in the SHR, but may record the LTM-related information in the RLF report. The RLF report can be subsequently sent to the network device as needed or upon receiving a request from the network device for the RLF report.

[0102] In some embodiments, the terminal records the LTM-related information in the SHR when a first condition is met, wherein the first condition includes at least one of the following:

[0103] The terminal stores LTM configuration information;

[0104] The terminal successfully performs a handover operation;

[0105] The second condition is met.

[0106] For example, the switching operation includes at least one of the following: an LTM switching operation, a traditional switching operation, a conditional switching operation, and a dual active protocol stack (DAPS) switching.

[0107] For example, if the terminal has stored LTM configuration information, meaning that the network device has configured the LTM configuration information for the terminal, and therefore the terminal has the potential to switch to LTM, it is necessary to send LTM-related information to the network device so that the network device can promptly and accurately determine whether to switch to LTM for the terminal. Therefore, in this case, the terminal can record the LTM-related information in the SHR so that when sending the SHR, the LTM-related information can also be sent to the network device.

[0108] For example, if the terminal has stored LTM configuration information, meaning that the network device has configured the LTM configuration information for the terminal and the terminal has executed an LTM switch, it is necessary to send LTM-related information to the network device so that the network device can promptly and accurately determine whether the LTM configuration and switch command are reasonable. Therefore, in this case, the terminal can record the LTM-related information in the SHR so that when sending the SHR, the LTM-related information can also be sent to the network device.

[0109] For example, if a terminal has stored LTM configuration information (that is, the network device has configured LTM for the terminal), and the terminal performs other types of handovers, such as traditional handovers, conditional handovers, or dual-active protocol stack handovers, it is also necessary to send LTM-related information to the network device so that the network device can promptly and accurately determine whether the current handover decision and handover configuration are reasonable. Therefore, in this case, the terminal can record LTM-related information in the SHR so that when sending the SHR, the LTM-related information can also be sent to the network device.

[0110] In some embodiments, the second condition includes a first timer satisfying a threshold condition, wherein the first timer includes at least one of the following:

[0111] T304 timer;

[0112] T310 timer;

[0113] T312 timer.

[0114] In some embodiments, the second condition may also be referred to as an SHR recording trigger condition.

[0115] For example, the T304 timer can be used to detect handover success or failure. When the UE receives a handover command, the T304 timer is started. If the handover is successful, the T304 timer is terminated. If the T304 timer times out, it indicates that the handover has failed.

[0116] For the T304 timer, the threshold corresponding to the T304 timer may be indicated to the terminal by the target cell during the handover process (e.g., the target cell during the LTM handover process). For example, the T304 timer meeting the threshold condition may include: a ratio of the timing value of the T304 timer to the configuration value of the T304 timer is greater than a T304 threshold percentage, wherein the T304 threshold percentage may be included in a successful handover configuration received before the last synchronous reconfiguration is performed, the configuration value of the T304 timer may be included in the last applied RRC reconfiguration message, and the RRC reconfiguration message may include the synchronous reconfiguration.

[0117] That is, the ratio between the value of the elapsed time of the timer T304 and the configured value of the T304 timer, included in the last applied RRCReconfiguration message including the reconfiguration With Sync, is greater than thresholdPercentageT304 if included in the successHO-Config received before executing the last reconfiguration with sync.

[0118] For example, the T310 timer can be used to monitor radio link failures. When a terminal detects a physical layer failure, it can start the T310 timer. Before the T310 timer expires, if the terminal detects that the physical layer failure has recovered, or triggers a handover process, or the terminal initiates a connection reestablishment process, the T310 timer is stopped. After the T310 timer expires, if the security mode is not activated, the terminal enters the RRC_IDLE state; otherwise, the RRC connection reestablishment process is triggered.

[0119] For the T310 timer, the threshold corresponding to the T310 timer may be indicated to the terminal by the source cell during the handover process (e.g., the source cell during the LTM handover process). For example, the T310 timer meeting the threshold condition may include: a ratio of the timing value of the T310 timer to the configuration value of the T310 timer is greater than a T310 threshold percentage, wherein the T310 threshold percentage may be included in the configuration of the source primary cell before the last synchronization reconfiguration is performed, and the configuration value of the T310 timer may be configured when the terminal is connected to the source primary cell before the last synchronization reconfiguration is performed.

[0120] That is, the ratio between the value of the elapsed time of the timer T310 and the configured value of the timer T310, configured while the UE was connected to the source PCell before executing the last reconfiguration with sync, is greater than thresholdPercentageT310 included in the successHO-Config if configured by the source PCell before executing the last reconfiguration with sync.

[0121] For example, the function of the T312 timer is similar to that of the T310 timer, but the timeout duration of the timer can be different, so that when the T312 timer is used, the reestablishment process can be triggered faster than when the T310 timer is used, thereby accelerating the RLF recovery process.

[0122] For the T312 timer, the threshold corresponding to the T312 timer may be indicated to the terminal by the source cell during the handover process (e.g., the source cell during the LTM handover process). For example, the T312 timer meeting the threshold condition may include: a ratio of the timing value of the T312 timer to the configured value of the T312 timer is greater than a T312 threshold percentage, wherein the T312 threshold percentage may be configured by the source primary cell before performing the last synchronization reconfiguration, and the configuration value of the T312 timer may be configured when the terminal is connected to the source primary cell before performing the last synchronization reconfiguration.

[0123] That is, the ratio between the value of the elapsed time of the timer T312 and the configured value of the timer T312, configured while the UE was connected to the source PCell before executing the last reconfiguration with sync, is greater than thresholdPercentageT312 included in the successHO-Config if configured by the source PCell before executing the last reconfiguration with sync.

[0124] It should be noted that the first timer can be a traditional timer, such as T304, T310, or T312 described above, or a newly defined timer. The newly defined timer can be dedicated to the LTM handover type and targeted at one or more specific LTM candidate cells. The logic for satisfying the threshold condition for the newly defined timer can be similar to that of the traditional timer, and the threshold percentages involved can be the same or different, which will not be further described in this disclosure.

[0125] It should be noted that the first timer meeting the threshold condition can be judged based on a common threshold condition, that is, without distinguishing the type of switching performed by the terminal, or it can be dedicated to the terminal recording LTM related information in the SHR to determine whether the second condition is met. It can be a configuration for one or more LTM candidate cells, or it can be a common configuration for all LTM candidate cells. This disclosure will not go into details about this.

[0126] In some embodiments, the LTM-related information includes at least one of the following:

[0127] Information of at least one cell;

[0128] Time information, wherein the time information is used to indicate the time interval from the terminal receiving the LTM configuration information to performing the LTM switching operation (for example, timeSinceLTM-Reconfig-r18).

[0129] In some embodiments, the information of the at least one cell includes at least one of the following:

[0130] Cell identification information (e.g., cell ID);

[0131] Measurement results corresponding to the cell;

[0132] Indication information corresponding to the cell, wherein the indication information is used to indicate whether the corresponding cell is an LTM candidate cell.

[0133] In some embodiments, the cell includes at least one of the following: a source cell, a target cell, a serving cell, a neighbor cell, or one or more LTM candidate cells.

[0134] There may be an association between the identification information of the cell and the measurement result of the cell. Accordingly, the terminal may determine the measurement result of the terminal in at least one cell according to the LTM related information in the SHR.

[0135] In some embodiments, the indication information corresponding to the cell may be 1-bit LTM indication information, used to indicate whether the cell recorded in the SHR is an LTM candidate cell. For example, 0 indicates that the cell is not an LTM candidate cell, and 1 indicates that the cell is an LTM candidate cell. Alternatively, 1 indicates that the cell is not an LTM candidate cell, and 0 indicates that the cell is an LTM candidate cell. Alternatively, the presence of the LTM indication information indicates that the cell is an LTM candidate cell, and the absence of the LTM indication information indicates that the cell is not an LTM candidate cell.

[0136] It should be noted that the present disclosure may also indicate whether the corresponding cell is an LTM candidate cell in other ways, not limited to the above-mentioned indication through LTM indication information. The specific indication method can be determined as needed, and the present disclosure does not limit this.

[0137] In some embodiments, the terminal may record identification information and corresponding measurement results of one or more neighboring cells in the SHR, wherein each neighboring cell corresponds to LTM indication information, and the LTM indication information is used to indicate whether the corresponding neighboring cell is an LTM candidate cell.

[0138] In some embodiments, the indication information corresponding to the cell may be a specific list, which includes at least one of the identification information of the cell and the measurement result corresponding to the cell. The list may indicate that the cell corresponding to the information in the list is an LTM candidate cell.

[0139] In some embodiments, the operation performed by the terminal on the cell includes at least one of the following: Minimization Drive Test (MDT) and Self-Organizing Network (SON).

[0140] In some embodiments, the terminal can measure the signal in the beam of the network device, for example, it can measure the synchronization broadcast signal block (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB) in the beam. Of course, the measured signal is not limited to measuring SSB, and other signals can also be measured, such as channel state information (Channel State Information Reference Signal, CSI-RS), etc. The embodiments of the present disclosure are not limited to this.

[0141] In some embodiments, the measurement result corresponding to the cell may include measurement results corresponding to one or more SSBs of the candidate cell of the LTM configuration information.

[0142] After the network device sends the LTM configuration information to the terminal, it needs to reserve some resources for the terminal so that when the terminal is triggered to perform LTM switching, the terminal can smoothly switch among the LTM candidate cells.

[0143] However, if resources are reserved for a terminal for a long time, the resources will not be available to other terminals for a long time, which, to a certain extent, causes a waste of resources.

[0144] According to this embodiment, the network device can determine whether the time interval from the terminal receiving the LTM configuration information to executing the LTM switching operation is too long based on the time information (for example, if the time interval is greater than the interval threshold, it can be determined that the time interval is too long), and then if the time interval is too long, the LTM configuration information can be adjusted.

[0145] For example, if the time interval between the terminal receiving the LTM configuration information and executing the LTM switching operation is greater than the interval threshold, the network device can adjust the LTM configuration information subsequently sent to the terminal, such as reducing the LTM candidate cells, which helps avoid resource waste caused by reserving resources for the terminal for a long time.

[0146] It should be noted that whether the network device adjusts the LTM configuration information according to the time information, and how to adjust the LTM configuration information, can be implemented based on the network device's own policy, or based on protocol agreement, or can be instructed by the core network function module (such as Access and Mobility Management Function (AMF)) or Operation Administration and Maintenance (OAM).

[0147] In some embodiments, the measurement result includes at least one of the following: a layer 1 (L1) measurement result; and a layer 3 measurement result. The measurement result may reuse existing resources or be a newly introduced independent field, which is not limited by the present disclosure.

[0148] For example, when a terminal measures a signal in a cell, the signal may first pass through a layer 1 filter to obtain a layer 1 measurement result, and then the layer 1 measurement result may be input into a layer 3 filter to obtain a layer 3 filtering result.

[0149] For example, the relevant parameters of the layer 1 filter may be determined based on the UE implementation specifics.

[0150] For example, relevant parameters of the layer 3 filter may be determined based on Radio Resource Control (RRC) configures parameters.

[0151] For example, the measurement result corresponding to the cell may include only the measurement result of L1; for example, the measurement result corresponding to the cell may include the measurement result of L1 and the measurement result of L3. For example, the measurement result corresponding to the cell may include only the measurement result of L3.

[0152] In some embodiments, when the measurement results corresponding to the cell only include L1 measurement results, the measurement results corresponding to the cell can be used by the network device to decide at least one of the following: whether to perform LTM, how to perform LTM (for example, on which time-frequency resources).

[0153] In some embodiments, when the measurement results corresponding to the cell include L1 measurement results and L3 measurement results, the measurement results corresponding to the cell can be used by the network device to decide at least one of the following: whether to perform LTM or to perform switching based on the L3 measurement results (for example, traditional HO, CHO, etc.), how to perform LTM (for example, on which time-frequency resources), and how to perform switching based on the L3 measurement results (for example, on which time-frequency resources).

[0154] In some embodiments, when the measurement results corresponding to the cell only include L3 measurement results, the measurement results corresponding to the cell can be used by the network device to decide at least one of the following: whether switching based on the L3 measurement results is reasonable, and whether LTM is still required.

[0155] As for whether the measurement result corresponding to the cell specifically includes the measurement result of L1, or includes the measurement result of L3, or includes the measurement result of L1 and the measurement result of L3, it can be indicated by the network device or agreed upon by the protocol.

[0156] In some embodiments, the layer 1 measurement result and the layer 3 measurement result may be measurement results for the same cell (eg, the layer 1 measurement result is the layer 1 measurement result for cell #1, and the layer 3 measurement result is the layer 3 measurement result for cell #1).

[0157] In some embodiments, the layer 1 measurement result and the layer 3 measurement result may be measurement results for different cells (for example, the layer 1 measurement result is the layer 1 measurement result for cell 1, and the layer 3 measurement result is the layer 3 measurement result for cell #2).

[0158] As to whether the layer 1 measurement result and the layer 3 measurement result are measurement results for the same cell or measurement results for different cells, the terminal may determine based on network device instructions or protocol agreements, and this disclosure does not limit this.

[0159] In some embodiments, since the layer 1 measurement results include physical layer measurement results, when the terminal sends an SHR to a network device through RRC signaling, the terminal may first perform internal interaction, for example, obtaining the layer 1 measurement results from the physical layer through the RRC layer, and then sending the SHR including the layer 1 measurement results to the network device through RRC signaling.

[0160] In some embodiments, the terminal sends capability information to the network device, wherein the capability information is used to indicate at least one of the following:

[0161] Whether the terminal supports recording the LTM related information in the SHR;

[0162] Whether the terminal supports sending the SHR to the network device.

[0163] In some embodiments, the terminal will inform the network device of its support for recording LTM-related information, recording LTM-related information in SHR, and sending SHR recorded with LTM-related information to the network device, so as to facilitate the network device to perform appropriate operations subsequently and avoid waste of resources.

[0164] For example, if the terminal supports recording the LTM related information in the SHR and supports sending the SHR to the network device, then the capability information sent by the terminal to the network device may indicate that the terminal supports recording the LTM related information in the SHR and supports sending the SHR to the network device.

[0165] In this case, when the network device needs LTM-related information, it may choose to send a request message to the terminal to request the terminal to send an SHR containing LTM-related information to the network device.

[0166] For example, the terminal supports recording the LTM related information in the SHR, but does not support sending the SHR to the network device. Then the capability information sent by the terminal to the network device can indicate that the terminal supports recording the LTM related information in the SHR, but does not support sending the SHR to the network device.

[0167] In this case, when the network device needs LTM-related information, it can choose to send a request message to other devices that can communicate with the terminal to request other devices to obtain SHR containing LTM-related information from the terminal, and then obtain SHR containing LTM-related information from other devices.

[0168] For example, the terminal does not support recording the LTM related information in the SHR, but supports sending the SHR to the network device. Then the capability information sent by the terminal to the network device can indicate that the terminal does not support recording the LTM related information in the SHR, but supports sending the SHR to the network device.

[0169] In this case, since the terminal does not record the LTM related information in the SHR, the network device does not need to attempt to obtain the LTM related information recorded by the terminal by requesting the SHR from the terminal.

[0170] In some embodiments, before recording the LTM related information in the SHR, the terminal may choose to first record the LTM related information in an SHR related report variable, for example, in a report variable VarSuccessHO-Report.

[0171] Of course, before the terminal records the LTM related information in the SHR, it is not limited to recording the LTM related information through reporting variables, and the LTM related information can also be recorded in other ways, which is not limited by the present disclosure.

[0172] In some embodiments, the SHR used to record LTM-related information can reuse the existing SHR, or a new SHR can be defined specifically for recording LTM-related information; in some embodiments, the SHR-related report variables used to record LTM-related information can reuse the existing SHR-related report variables (such as VarSuccessHO-Report), or a new SHR-related report variable can be defined specifically for recording LTM-related information.

[0173] In some embodiments, when the terminal sends the SHR recording LTM-related information to the network device, it can also indicate the identifier of the LTM candidate cell (for example, the identifier of the available LTM candidate cell) to the network device. The network device can determine the LTM candidate cell based on the identifier of the LTM candidate cell, and then forward the SHR sent by the terminal to the LTM candidate cell.

[0174] In some embodiments, the terminal may further send availability indication information to the network device, where the availability indication information is used to indicate at least one of the following: available LTM-related information stored in the terminal, and available LTM candidate cells (e.g., identifiers indicating LTM candidate cells). Based on this, the network device determines which LTM candidate cell is available and / or determines whether available LTM-related information is stored in the terminal.

[0175] In some embodiments, the availability indication information may reuse traditional availability indication information; or it may be newly defined availability indication information, which may be specifically used to indicate that available LTM-related measurement results and / or available LTM candidate cells are stored in the terminal.

[0176] In addition, in some embodiments, the report used to record LTM-related information is not limited to SHR (such as traditional SHR or newly defined SHR). For example, LTM-related information can also be recorded through other reports. Other reports can be traditional reports, such as traditional SON reports (such as traditional RLF reports, traditional CEF reports, etc.), traditional MDT reports, etc.; they can also be newly defined reports, such as newly defined SON reports (such as newly defined RLF reports, newly defined CEF reports, etc.), such as newly defined MDT reports.

[0177] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0178] In some embodiments, step S201 may be performed in a swapped order or simultaneously.

[0179] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0180] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
