Description

Technical Field

[0001] The present invention relates to the field of mobile communications, and in particular to an information processing method and device. Background Art

[0002] Currently, in the Multi-Radio Dual Connectivity (MR-DC) scenario, the terminal can interact with the Master Cell Group (MCG) and the Secondary Cell Group (SCG) at the same time. If a Radio Link Failure (RLF) occurs in the MCG, the terminal (User Equipment, UE) will record the relevant information of the Primary Cell (PCell) (such as the cell ID of the PCell) and the cause of the failure (such as T310 timer timeout, etc.) in the RLF report.

[0003] However, in the DC scenario, no matter whether RLF occurs in MCG or SCG, for the network side equipment, based on the RLF report recorded in the current method, the network side equipment can only determine the cause of the failure of PCell and the related failure information of PCell, but cannot determine the specific cause of the failure of MCG and / or SCG side in the DC scenario, for example, what is the reason for the failure of fast MCG failure recovery or the failure of SCG side, etc., which leads to the network side equipment being unable to accurately locate the cause of the failure, thereby affecting the optimization performance of the network side equipment for network optimization based on the RLF report.

In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0169] To facilitate understanding, the technical background of the embodiments of the present invention is first introduced below.

[0170] In the MR-DC dual-connection architecture, there may be one MN and one or more SNs. Both MN and SN nodes can be LTE / e-LTE / NR nodes. The cell group on the MN side is the primary cell group (MCG), which consists of one primary cell (PCell) and one or more secondary cells (SCell); the cell group on the SN side is the secondary cell group (SCG), which also consists of one primary cell (PSCell) and one or more secondary cells. The UE can interact with the MCG and SCG for data at the same time. When the network decides to add / replace an SN node for the UE or modify the SCG wireless resource configuration for the SN node, it can be done using the RRC reconfiguration message. If the resources of the SN node need to be used, a random access process for the SN node needs to be initiated.

[0171] In the MR-DC dual-connection architecture, there are several situations:

[0172] 1.MCG Failure Recovery (MCG failure discovery) process.

[0173] In MR-DC, a UE can interact with MCG and SCG at the same time. When a radio link failure occurs in the MCG on one side, the connection is disconnected. The UE can start the T316 timer and report the MCG Failure Information message to the network. The MCG Failure Information message includes the failure type and related measurement result information, informing the network that the MCG connection is disconnected and waiting for the network decision. Currently, the UE will only send the MCG Failure Information message to the network in the case of a radio link failure (RLF).

[0174] The MCG Failure Information message is sent by the UE to the network through the SN side. After receiving the MCG Failure Information message, the network can decide to send an RRC reconfiguration message, an RRC release message, or a mobilityFromNRCommand or mobilityFromEutraCommand message that supports inter-rat switching to the UE based on the failure cause and measurement results reported by the UE. When the UE receives the RRC reconfiguration or mobilityFromNRCommand, mobilityFromEutraCommand message, the UE will stop the T316 timer, start the T304 timer and perform the PCell switching process. If the switching is successful, the T304 timer will be stopped, the UE's MCG will restore the connection, and a completion message will be sent to the network. If the switching fails, the UE will initiate the reconstruction process after T304 times out. When receiving the RRC release message sent by the network device, the UE will return to the idle / inactivate state. After receiving the above message, the UE will delete the stored RLF Report.

[0175] When RLF occurs on the MCG side and causes the connection to be disconnected, the following situations may also exist: (1) The network equipment does not configure T316 for the UE; (2) The SCG side is in a suspended state at this time; (3) The SCG can transmit normally, turns on T316, sends a MCG Failure Information message, and RLF occurs on the SCG before receiving the RRC feedback message sent by the network; (4) The SCG can transmit normally, turns on T316, sends a MCG Failure Information message, and T316 times out before receiving the RRC feedback message sent by the network.

[0176] In the above cases, the UE will store the RLF Report and trigger the reestablishment. The UE will send an RLF Report available indication in the uplink completion message, and when the network requests, report the RLF Report to the network for failure analysis and optimization.

[0177] 2. SCG Failure Recovery Process

[0178] In MR-DC, a UE can interact with MCG and SCG at the same time. When the SCG on one side fails due to radio link failure, synchronization reconfiguration failure, SCG configuration failure, or SCG integrity check failure, the UE reports an SCG Failure Information message to the network. The message includes the failure type and related measurement result information, notifying the network that the SCG connection is disconnected and waiting for the network decision. Currently, the UE will only send an SCG Failure Information message when there is a radio link failure, synchronization reconfiguration failure, SCG configuration failure, or SCG integrity check failure.

[0179] The SCG Failure Information message is sent by the UE to the network through the MN side. After receiving the SCGFailure Information message, the network can decide to send an RRC reconfiguration message and an RRC release message to the UE based on the failure cause and measurement results reported by the UE. When the UE receives the RRC reconfiguration message, the UE will start the T304 timer and perform the PSCell switching process. If the switching is successful, the T304 timer will be stopped, the UE's SCG will resume the connection, and a completion message will be sent to the network device. If the PSCell switching fails, the SCGFailure Information will continue to be sent to the network device until the network device suspends / releases the SCG or successfully restores the SCG connection.

[0180] When RLF occurs on the SCG side and causes the connection to be disconnected, UE reestablishment will be triggered in the following two cases: (1) the MCG side is in a suspended state at this time; (2) the MCG can transmit normally and send an SCG Failure Information message, and the MCG has an RLF before receiving the RRC feedback message sent by the network.

[0181] 3. Both MCG and SCG failed.

[0182] When a failure occurs on the MCG side and the MCG Failure Information is sent through the SCG side, it is found that a failure also occurs on the SCG side, or when the MCG Failure Information message is sent but the RRC feedback message sent by the network has not been received, the SCG side has also failed; When a failure occurs on the SCG side and the SCG FailureInformation is sent through the MCG side, it is found that a failure also occurs on the MCG side, or when the SCG Failure Information message is sent but the RRC feedback message sent by the network has not been received, the MCG side has also failed. At this time, the UE will initiate an RRC reconstruction process to restore the connection.

[0183] It can be seen that in the MR-DC dual-connection architecture, the network conditions that lead to MCG failure and SCG failure are relatively complex. According to the existing method, the terminal will only generate an RLF report when an RLF occurs in the MCG, and the RLF report only contains the cause of the PCell failure and related information of the PCell, which will be very unfavorable for network analysis of the specific causes of the MCG failure and SCG failure, thereby resulting in poor network optimization effect.

[0184] For example, when RLF occurs in MCG, if T316 timer is configured and SCG can transmit normally, T316 timer can be started and MCG failure information message can be sent to network device through SCG, or when RLF occurs in SCG, SCG failure information message can be sent to network device through MCG. Rapid recovery or release is performed according to the Radio Resource Control (RRC) feedback information sent by the network device.

[0185] However, in a dual-connection scenario, when RLF occurs in MCG, the terminal can also send an MCG failure information message to the network device through SCG, so that the network device can change the configuration parameters or instruct the network device to release MCG, and send the final decision information to the terminal by sending an RRC feedback message. The terminal updates the configuration parameters based on the feedback message for rapid recovery, or releases MCG. If the recovery or release of MCG is successful, the RLF report will be deleted. If the recovery fails, after entering the connection state again, the indication that the terminal stores the RLF report will be reported in the uplink completion information, and when the network device sends a request for the terminal to report the RLF report, the terminal will send the RLF report to the network device. Therefore, the reason for the wireless link failure may also be that RLF also occurs in SCG. Therefore, in a dual-connection scenario, the RLF report currently reported by the terminal is not perfect enough, and the network device cannot accurately locate the cause of the failure based on the current RLF report.

[0186] In order to make the RLF report reported by the terminal more complete in a dual connection scenario, the present application provides a scheme for an information processing method. In this scheme, when the terminal detects that RLF occurs in SCG and / or MCG, the stored RLF report includes not only relevant information of RLF occurring in MCG, but also relevant information of RLF occurring in SCG, so that the content recorded in the RLF report is more complete, and the network equipment can more accurately locate the cause of failure and determine the optimization plan.

[0187] After introducing the design ideas of the embodiments of the present application, the following briefly introduces the application scenarios to which the technical solutions of the embodiments of the present application can be applied. It should be noted that the application scenarios introduced below are only used to illustrate the embodiments of the present application and are not limited. In specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0188] See also Figure 1 As shown, Figure 1 An application scenario in which the technical solution of the embodiment of the present application can be used. In this application scenario, a master node (Master Node, MN) 11, at least one secondary node (Secondary Node, SN) 12, a network device 13 and a terminal 10 are included. Among them, the MN node 11 and the SN node 12 can both be LTE / e-LTE / NR nodes, the cell group on the MN side is MCG, which is composed of a PCell and at least one secondary cell (Secondary Cell, SCell), and the cell group on the SN side is SCG, which is composed of a primary SCG Cell (PSCell) and at least one SCell. The terminal 10 can interact with MCG and SCG at the same time. The network device 13 can add / replace SN nodes for the terminal 10 through RRC configuration messages, and modify the wireless resource configuration for the MN node and the SN node. When the terminal 10 needs to use the SN node, it can initiate random access according to the RRC configuration information sent by the network device 13. The terminal 10 may be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The network device 13 may be a base station, and the base station may be a commonly used base station, an evolved Node Base station (eNB), or a network side device in a 5G system (e.g., a next generation Node Base station (gNB)).

[0189] In the embodiment of the present application, the terminal 10 detects whether RLF occurs in the MCG and / or SCG, and when it is determined that RLF occurs, stores the RLF report, and sends the generated report to the network device 13 when a preset condition is met.

[0190] The technical solution provided by the embodiments of the present application is introduced below in conjunction with the drawings in the specification.

[0191] See also Figure 2 As shown, Figure 2 A flow chart of an information processing method provided in an embodiment of the present application. Figure 2 The flow chart of the method described is as follows:

[0192] Step 201: The terminal detects whether RLF occurs in MCG and / or SCG.

[0193] Step 202: When the terminal detects that RLF occurs in the MCG and / or SCG, the terminal stores the RLF report.

[0194] In an embodiment of the present application, the RLF report includes first information for indicating that RLF occurs in the MCG, and / or second information for indicating that RLF occurs in the SCG. When the detection results are different, the contents recorded in the RLF report may be different.

[0195] Specifically, the detection results include: RLF occurs in MCG and SCG can transmit data normally, RLF occurs in SCG and MCG can transmit data normally, and RLF occurs in MCG and SCG. Among them, RLF occurs in MCG and SCG includes: first detecting that RLF occurs in MCG and then detecting that RLF occurs in SCG, and first detecting that RLF occurs in SCG and then detecting that RLF occurs in MCG. The following describes the contents of the first information and / or second information in the RLF report corresponding to each result.

[0196] 1. When the detection result is that RLF occurs in MCG and SCG can transmit data normally, the RLF report only contains the first information indicating that RLF occurs in MCG. At this time, the first information includes at least one or more of the relevant information of failure on the MCG side (for example: failure type of MCG, measurement results configured by MN, etc.), relevant information of T316 timer, DC indication and measurement results configured by SN. The failure type may be, for example, RLF or handover failure.

[0197] That is to say, for this situation, compared with the existing technical solutions, the first information contained in the RLF report is also supplemented. The supplemented information includes: T316 timer related information, DC indication and SN configuration measurement results, etc., so that the network equipment can more accurately locate the cause of RLF in MCG based on the content of the RLF report, and then optimize the network in a more targeted manner.

[0198] 2. When the detection result is that RLF occurs in the SCG and the MCG can transmit data normally, the RLF report only contains the second information used to indicate that RLF occurs in the SCG. At this time, the second information includes relevant information on the failure on the SCG side (for example: the failure type of the SCG, the measurement results of the SN configuration, etc.), DC indication and at least one of the measurement results of the MN configuration.

[0199] 3. When the detection result is that RLF occurs in MCG and SCG, the RLF report includes DC indication information, T316 timer related information, RLF report related to MCG side failure, MCG side failure related information, RLF report related to SCG side failure, SCG side failure related information, and time indication information used to indicate the order in which RLF occurs in MCG and SCG, etc. It should be noted that the information contained in the RLF can also be divided into first information used to indicate RLF occurs in MCG, second information used to indicate RLF occurs in SCG, and other information, wherein the first information includes at least one of DC indication information, T316 timer related information, RLF report related to MCG side failure, and MCG side failure related information; the second information includes RLF report related to SCG side failure, and SCG side failure related information; and other information may refer to time indication information used to indicate the order in which RLF occurs in MCG and SCG, etc.

[0200] That is to say, when the detection result is that RLF occurs in MCG and SCG, the RLF report sent may also include two sub-RLF reports, namely, the RLF report related to the failure on the MCG side and the RLF report related to the failure on the SCG side.

[0201] It should be noted that the RLF report related to MCG side failure can be understood as a report generated by recording relevant content when RLF occurs in MCG, and the RLF report related to SCG side failure can be understood as a report generated by recording relevant content when RLF occurs in SCG.

[0202] Among them, the relevant information of the failure on the SCG side includes the failure type of the SCG, the measurement results of the SN configuration, the random access channel (RACH) related information of the SCG, the cell ID of the primary and secondary cell PSCell where the RLF occurs, the cell IDs of the source PSCell and the target PSCell when the PSCell switching fails, the time from the initialization / execution of the PSCell switching to the failure, the time from the failure of the PSCell to the reporting of the RLF report, the time from the failure of the PSCell to the re-entry into the connection state, and at least one of the indication information that the SCG is performing a PSCell switching or a PSCell adding. Among them, if the relevant information about the failure on the SCG side in the RLF report includes the indication information that the SCG is performing a PSCell switching or a PSCell adding, it indicates that the MCG has already had an RLF, the SCG is performing a PSCell addition or a PSCell change process, and data transmission can no longer be performed normally. It should be noted that the above-listed PSCell related information is only a part of it, and other similar related information is also to be protected by this application. What specific information is included will not be repeated here.

[0203] The relevant information about the failure on the MCG side includes the failure type of the MCG, the measurement results configured by the MN, the RACH related information of the MCG, the cell ID of the PCell where the RLF occurs, the cell IDs of the source PCell and the target PCell when the PCell switching fails, the time from the initialization / execution of the PCell switching to the failure, the time from the failure of the PCell to the reporting of the RLF report, the time from the failure of the PCell to the re-entry into the connected state, and at least one of the indication information that the MCG is performing a PCell switching. Among them, if the relevant information about the failure on the MCG side in the RLF report includes the indication information that the MCG is performing a PCell switching, it indicates that the SCG has already experienced a RLF at this time, and the MCG is performing a PCell switching process and cannot perform data transmission normally. It should be noted that the above-listed PCell related information is only a part of it, and other similar related information is also to be protected by this application. What specific information is included will not be repeated here.

[0204] The value of T316 is used to indicate whether the terminal is configured with T316, and when T316 is configured, the recording form of the value of T316 can be indicated by a bit value display, for example, "1" is used to indicate that T316 is configured, or the running time configured by the network device for T316 can be directly recorded, or the running time of T316 can be directly recorded, or a second identifier can be used to indicate whether T316 has timed out. When T316 is not configured, the value of T316 can be implicitly indicated by a bit value, for example, "0" is used to indicate that T316 is not configured.

[0205] In a possible implementation, the recording format of the order in which RLF occurs in MCG and SCG may be indicated by a first identifier, for example, 1 bit explicitly indicates that RLF occurs in MCG before SCG, and implicitly indicates that RLF occurs in SCG before MCG, or 1 bit implicitly indicates that RLF occurs in MCG before SCG, and explicitly indicates that RLF occurs in SCG before MCG; or directly records the absolute time or relative time when RLF occurs in MCG, and the absolute time or relative time when RLF occurs in SCG; or directly records the time difference, for example, when the difference result is negative, it indicates that RLF occurs in SCG first, and when the difference result is positive, it indicates that RLF occurs in MCG first. Among them, absolute time refers to a moment. For example, the recorded time when RLF occurred in MCG is 2021 / 5 / 3 22:45:03, which means that RLF occurred in MCG at 22:45:03 on May 3, 2021. Relative time refers to the time with a certain moment as a reference. For example, the time when the terminal is turned on is used as the reference time. The recorded time when RLF occurred in MCG is 00:30:45, which means that RLF occurred in MCG 30 minutes and 45 seconds after the terminal was turned on.

[0206] In a specific implementation process, when a network device receives an RLF report reported by a terminal, it can be known based on the content included in the report whether it is the MCG or the SCG where the RLF occurs, or whether the MCG or the SCG experiences the RLF first.

[0207] For example, the content of the RLF report includes the type of MCG failure, the measurement results configured by the MN, the T316 timer related information, the DC indication, and the measurement results configured by the SN. Based on this content, the network device can know that the MCG has an RLF and that the SCG can transmit data normally. At this time, the network device can also determine whether the cause of the RLF is the non-configuration of the T316 timer or other reasons based on the T316 timer related information.

[0208] For example, the content of the RLF report includes the failure type of the SCG, the measurement results of the SN configuration, the DC indication, and the measurement results of the MN configuration. Based on the content, the network device can know that the SCG has an RLF and the MCG can transmit data normally.

[0209] For example, the content of the RLF report includes DC indication, T316 timer related information, time indication information, MCG failure related information and SCG failure related information. Based on the content, the network device can know whether RLF has occurred in MCG and SCG, and whether RLF occurs first in MCG or SCG.

[0210] In a possible implementation, when the terminal determines that RLF occurs in MCG and SCG, the RLF report may further include time indication information, which is used to indicate whether the terminal first detects that RLF occurs in MCG or SCG. At this time, the network device can determine based on the time indication information whether SCG has been suspended by the network device when RLF occurs in MCG or RLF occurs after SCG sends an MCG failure information message, or whether MCG has been suspended by the network device when RLF occurs in SCG or RLF occurs after MCG sends an SCG failure information message.

[0211] Assume that the time indication information includes the first time indication information and the second time indication information. For example, the first time indication information is used to indicate that the terminal first detects that the MCG has RLF, and then detects that the SCG has also RFL, and the second time indication information indicates that the SCG has RLF first. The network device can determine that the SCG has been suspended by the network device before the MCG has RLF based on the first time indication information and the second time indication information.

[0212] For another example, the first time indication information is used to indicate that the terminal first detects that RLF occurs in MCG and then detects that RFL also occurs in SCG. The second time indication information indicates that RLF occurs first in MCG. The network device can determine, based on the first time indication information and the second time indication information, that RLF occurs in SCG after SCG sends the MCG failure information message and before MCG receives the RRC feedback information sent by the network device.

[0213] In the specific implementation process, compared with the content of the existing RLF report, the RLF report of this application can enable the network equipment to know more and more specific reasons for the RLF occurrence of MCG and / or SCG, thereby more accurately locating the cause of failure and determining the corresponding optimization plan.

[0214] Step 203: When a preset condition is met, the terminal sends an RLF report to the network device.

[0215] In an embodiment of the present application, when the terminal detects that RLF occurs in the MCG and the SCG is able to perform data transmission, if it is detected that T316 is configured, the terminal can also send MCG failure indication information to the network device through the SCG. The network device can change the wireless resource configuration of the MN based on the MCG failure indication information to enable the MCG to quickly restore the connection, and then send the RRC configuration information to the terminal. The terminal is updated according to the RRC configuration information. At this time, if the MCG is successfully recovered, the terminal sends a successful recovery message to the network device and deletes the recorded RLF report. If the MCG recovery fails, the terminal stores the RLF report for reporting the report to the network device when the preset conditions are met. If it is detected that T316 is not configured, the terminal saves the RLF report and reports the report to the network device when the preset conditions are met.

[0216] The preset condition is, for example, that the terminal receives a request message sent by the network device to request the terminal to report the RLF report.

[0217] In one possible implementation, when MCG recovery fails or T316 is not configured, the terminal needs to send a reconstruction request to the network device when saving the RLF report; or if the reconstruction is not successful within the preset time, the terminal will send a connection establishment request to the network device; or when the connection is restored, the terminal sends a connection recovery request to the network device, or when the connection is reconfigured, the terminal sends a connection reconfiguration request to the network device, and when the reconstruction is successful or the connection is successfully established or the connection is successfully restored or the connection is reconfigured, an uplink completion message will be sent to the network device, and the uplink completion message will carry an available indication of the stored RLF report. After receiving the available indication, the network device determines whether the terminal needs to report the RLF report. If it is determined that the report is required, the network device will send a request message for the RLF report to the terminal.

[0218] In some embodiments, when the terminal detects that RLF occurs in the SCG and the MCG can transmit data normally, the terminal sends SCG failure indication information to the network device through the MCG. The network device can change the RRC configuration information of the SN according to the SCG failure indication information and send the RRC configuration information to the terminal. The terminal can switch the PSCell according to the configuration information or update the configuration information for fast connection recovery. If the recovery fails, the SCG failure indication information is sent again through the MCG until the connection is restored, or the network device suspends the SCG, or releases the SCG, or the MCG also has RLF.

[0219] Step 204: The network device sends the RLF report to the MN node and / or the SN node.

[0220] In the embodiment of the present application, when the network device receives the RLF report sent by the terminal, the RLF report can be sent to the source MN and the source SN according to the cell ID of the source PCell and the cell ID of the source PSCell, wherein the source MN includes the MCG and the source SN includes the SCG;

[0221] Alternatively, an RLF report is sent to the source MN according to the cell ID of the source PCell, or an RLF report and first indication information instructing the source MN to send the RLF report to the source SN according to the cell ID of the source PSCell, so that the source MN and the source SN can know the cause of the RLF and optimize the MCG and SCG respectively.

[0222] In order to better understand the technical solution of the present application, the information processing method provided by the present application will be explained below in conjunction with specific embodiments.

[0223] Example 1: When RLF occurs in MCG, SCG is in suspended state.

[0224] Step 1: The network configures DC for the UE.

[0225] Step 2: RLF occurs in the SCG and the SCG Failure Information message is sent to the network through the MCG.

[0226] Step 3: RLF occurs in MCG before the UE receives the RRC feedback message sent by the network device.

[0227] Step 4: The UE stores the radio link failure report (RLF) and records in the radio link failure report the time indication information used to indicate that the radio link failure occurred in the MCG and the radio link failure occurred in the SCG, the relevant information of the radio link failure occurred in the MCG, the correlation information of the radio link failure occurred in the SCG, the T316 timer related information and the DC indication information.

[0228] The relevant information of the radio link failure of the MCG includes the measurement result of the SN configuration. The measurement result of the SN configuration here can be understood as the measurement result measured by the UE according to the measurement configuration configured by the SN when the radio link failure occurs in the MCG.

[0229] The correlation information of radio link failure of SCG includes the measurement result configured by MN. Here, the measurement result configured by MN can be understood as the measurement result measured by UE according to the measurement configuration configured by MN when radio link failure occurs in SCG.

[0230] Step 5: UE initiates the reestablishment process.

[0231] Step 6: After the UE enters the connected state, it reports a radio link failure report in the uplink completion message to obtain an indication.

[0232] Step 7: The network sends a UE information request message to request the UE to report a radio link failure report.

[0233] Step 8: The UE reports a radio link failure report in a UE information request response message.

[0234] Step 9: The network analyzes the reasons for the wireless link failure and the fast MCG failure recovery failure and finds that the fast MCG failure recovery failure is caused by SCG suspension. The network is optimized accordingly.

[0235] Example 2: When RLF occurs in MCG, UE is not configured with T316

[0236] Step 1: The network configures DC for the UE.

[0237] Step 2: RLF occurs in MCG.

[0238] Step 3: The UE records the radio link failure report and records the following information in the radio link failure report: 1 bit indicates that T316 and MCG are not configured and related information about the radio link failure occurs.

[0239] The relevant information of the radio link failure of the MCG includes the measurement result of the SN configuration. The measurement result of the SN configuration here can be understood as the measurement result measured by the UE according to the measurement configuration configured by the SN when the radio link failure occurs in the MCG.

[0240] Step 4: UE initiates the reestablishment process.

[0241] Step 5: After the UE enters the connected state, it reports a radio link failure report in the uplink completion message to obtain an indication.

[0242] Step 6: The network sends a UE information request message to request the UE to report a radio link failure report.

[0243] Step 7: The UE reports a radio link failure report in the UE information request response message.

[0244] Step 8: The network analyzed the reasons for the wireless link failure and the fast MCG failure recovery failure and found that the fast MCG failure recovery failure was caused by the failure to configure T316. The network was optimized accordingly.

[0245] Example 3: MCG fails, SCG fails when T316 is running

[0246] Step 1: The network configures DC for the UE.

[0247] Step 2: RLF occurs in MCG and MCG Failure Information message is sent to the network through SCG.

[0248] Step 3: Before the UE receives the RRC feedback message sent by the network device, RLF occurs in the SCG.

[0249] Step 4: The UE records the wireless link failure report and records in the wireless link failure report the time indication information used to indicate that the wireless link failure occurred in the MCG and the SCG, the relevant information of the wireless link failure occurred in the MCG, the correlation information of the wireless link failure occurred in the SCG, the T316 timer related information and the DC indication information.

[0250] The relevant information of the radio link failure of the MCG includes the measurement result of the SN configuration. The measurement result of the SN configuration here can be understood as the measurement result measured by the UE according to the measurement configuration configured by the SN when the radio link failure occurs in the MCG.

[0251] The correlation information of radio link failure of SCG includes the measurement result configured by MN. Here, the measurement result configured by MN can be understood as the measurement result measured by UE according to the measurement configuration configured by MN when radio link failure occurs in SCG.

[0252] Step 5: UE initiates the reestablishment process.

[0253] Step 6: After the UE enters the connected state, it reports a radio link failure report in the uplink completion message to obtain an indication.

[0254] Step 7: The network sends a UE information request message to request the UE to report a radio link failure report.

[0255] Step 8: The UE reports a radio link failure report in a UE information request response message.

[0256] Step 9: The network analyzes the reasons for the failure of the wireless link and the failure of fast MCG failure recovery. It is found that the failure of fast MCG failure recovery is caused by the failure of SCG during the operation of T316. The network is optimized accordingly.

[0257] Example 4: MCG fails and T316 times out

[0258] Step 1: The network configures DC for the UE.

[0259] Step 2: RLF occurs in MCG and MCG Failure Information message is sent to the network through SCG.

[0260] Step 3: When the UE has not received the RRC feedback message sent by the network device, T316 times out;

[0261] Step 4: The UE records the radio link failure report and records the value of T316 in the radio link failure report, and related information about the radio link failure of the MCG.

[0262] The relevant information of the radio link failure of the MCG includes the measurement result of the SN configuration. The measurement result of the SN configuration here can be understood as the measurement result measured by the UE according to the measurement configuration configured by the SN when the radio link failure occurs in the MCG.

[0263] Step 5: UE initiates the reestablishment process;

[0264] Step 6: After the UE enters the connected state, it reports a radio link failure report in the uplink completion message to obtain an indication;

[0265] Step 7: The network sends a UE information request message to request the UE to report a radio link failure report;

[0266] Step 8: The UE reports a radio link failure report in a UE information request response message;

[0267] Step 9: The network analyzes the reasons for the wireless link failure and the fast MCG failure recovery failure and finds that the fast MCG failure recovery failure is caused by T316 timeout. The network is optimized accordingly.

[0268] Example 5: Radio link failure occurs on the SN side, and the radio link failure report of the PSCell is recorded

[0269] When a wireless link failure occurs on the SN side and the wireless link failure report of the PSCell is recorded, and SCGFailure Information is sent through the MCG side, it is found that a failure also occurs on the MCG side, or when the SCG FailureInformation message is sent and the RRC feedback message sent by the network has not been received, a failure also occurs on the MCG side. At this time, the time indication information for indicating that a wireless link failure occurs on the MCG and the SCG, related information on the wireless link failure of the MCG, correlation information on the wireless link failure of the SCG, related information on the T316 timer and DC indication information can be recorded.

[0270] The relevant information of the radio link failure of the MCG includes the measurement result of the SN configuration. The measurement result of the SN configuration here can be understood as the measurement result measured by the UE according to the measurement configuration configured by the SN when the radio link failure occurs in the MCG.

[0271] The correlation information of radio link failure of SCG includes the measurement result configured by MN. Here, the measurement result configured by MN can be understood as the measurement result measured by UE according to the measurement configuration configured by MN when radio link failure occurs in SCG.
