- Embodiment 2 is a diagram of a method for analyzing a link failure reason according to Embodiment 2 of the present invention.
- This embodiment takes the problem of the physical link as an example for description. As shown in Figure 2, the method includes:
- Step 201 The user equipment UE determines that the link failure belongs to the downlink physical link.
- the link failure is determined to be a problem of the downlink physical link.
- Step 202 determining whether the measurement report is triggered; performing step 203 if the measurement report is triggered, otherwise performing step 205;
- any existing method can be used to determine whether to trigger a measurement report, such as by judging Whether an event triggering the measurement report occurs is determined, for example, when the signal strength/quality of the neighbor cell is greater than the signal strength/quality threshold of the serving cell, the measurement report is triggered.
- Step 203 When it is determined in step 202 that the measurement report is triggered, the UE may determine that the cause of the link failure is a handover configuration problem;
- the handover configuration problem may be that the UE's handover parameter for the target cell (eg, cell-specific offset CelllndividualOffset, see TS36.331) is set too small, resulting in the UE's signal in the received serving cell. When it is weak, the UE has not completed the handover.
- the target cell eg, cell-specific offset CelllndividualOffset, see TS36.331
- Step 204 The UE records the analysis result.
- the UE may record the analysis result "switching configuration problem" in this case in the link failure report, and transmit the report to the network side through the report, but the present invention is not limited to this case.
- the analysis results are recorded separately and transmitted to the network side for the network side to analyze the cause of the link failure or to optimize the network.
- the analysis result may be recorded as follows: “switching configuration problem (physical link problem; measurement report triggered)”; or “switching configuration problem (T310 timeout; measurement report) Triggered) "etc;
- measurement report trigger is optional information, and may not be recorded.
- Step 205 When it is determined in step 202 that the measurement report is not triggered, the UE may further determine whether there is a neighbor cell with better signal quality; if the determination result is yes, step 206 is performed, otherwise step 208 is performed.
- Step 206 When the result of the determination in step 205 is YES, the UE may determine that the cause of the link failure is a handover configuration problem;
- the handover configuration problem may be that the UE's handover parameter for the target cell (eg, cell-specific offset CelllndividmlOffset, see TS36.331) is set too small, resulting in the UE's signal in the received serving cell. When it is weak, the UE has not completed the handover.
- the target cell eg, cell-specific offset CelllndividmlOffset, see TS36.331
- Step 207 The UE records the analysis result.
- the UE may record the analysis result "switching configuration problem" in this case in the link failure report, and transmit the report to the network side through the report, but the present invention is not limited to this case.
- the analysis results are recorded separately and transmitted to the network side for the network side to analyze the cause of the link failure or to optimize the network.
- the analysis result may be recorded as follows: “switching configuration problem (physical link problem; measurement report not triggered; neighboring cell with good signal quality)”; or “ Switching configuration problems (T310 timeout; measurement report not triggered; neighboring cells with better signal quality)” Among them, the recorded information "measurement report is not triggered; there is a neighboring cell with better signal quality” is optional information, and may not be recorded.
- Step 208 When the result of the determination in step 205 is no, the UE may further determine whether there is a recent successful UL transimi ssion before the link fails; in the case that there is a recent successful uplink transmission, the execution is performed. Step 209, otherwise step 211 is performed;
- the recent successful uplink transmission refers to: A successful uplink transmission occurs before a downlink problem occurs (such as receiving consecutive N310 out-of-sync indications from the bottom layer).
- Step 209 If the result of the determination in step 208 is that there is a recent successful uplink transmission, determine that the cause of the link failure is "covering the hole";
- the coverage hole refers to that the user equipment UE cannot successfully transmit the data packet in the uplink direction, and/or receives the data packet in the downlink direction;
- Step 210 The UE records the analysis result.
- the UE may record the analysis result "coverage hole" in this case in the link failure report, and transmit the report to the network side through the report, but the present invention is not limited to this case, and the analysis may be performed. The results are recorded separately and transmitted to the network side for the network side to analyze the cause of the link failure or to optimize the network.
- the analysis result may be recorded as follows: coverage hole (physical link problem; measurement report is not triggered; there is no neighbor cell with better signal quality; there is recent successful uplink “Transmission” "; or "covering the hole (T310 timeout; measurement report not triggered; there is no neighboring cell with good signal quality; there is recent successful uplink transmission)” and other methods;
- the "there is no neighboring cell with better signal quality; there is a recent successful uplink transmission" is optional information, and may not be recorded.
- Step 211 If the result of the determination in step 208 is that there is no recent successful uplink transmission, determine that the cause of the link failure is "covering the hole";
- Step 212 The UE records the analysis result.
- the UE may record the analysis result "coverage hole” in this case in the link failure report, and transmit the report to the network side through the report, but the present invention is not limited to this case, and the analysis may be performed.
- the results are recorded separately and transmitted to the network side for the network side to analyze the cause of the link failure or to optimize the network.
- the analysis result may be recorded as follows: coverage hole (physical link problem; measurement report not triggered; no neighboring cell with good signal quality; no recent successful uplink) "Transmission”"; or “covering holes (T310 timeout; measurement report not triggered; no neighboring cell with good signal quality; no recent successful uplink transmission)” etc.
- the "measurement report is not triggered; there is no neighboring cell with better signal quality; there is no recent successful uplink transmission" as optional information, and may not be recorded.
- Steps 213, 214, 215, and 216 the UE sends the analysis result to the network side;
- the analysis result may be sent to the network side in the link failure report, or may be sent separately; in addition, the analysis result may be sent when the network side requests to send.
- steps 204, 207, 210, and 212 are optional steps.
- the process shown in FIG. 2 is only an embodiment of the present invention, and may be used by those skilled in the art. Set the steps as required. As long as the following is true: When the measurement report is triggered, the cause of the link failure is determined as the handover configuration problem. When the measurement report is not triggered and there is a neighboring cell with good signal quality, determine the link failure. The reason is that the configuration problem is switched.
- the reason for determining the link failure is only the downlink coverage hole;

- Step 301 The user equipment UE determines that the link failure belongs to the RLC layer transmission problem.
- the UE when the UE transmits data to the base station, if the base station does not correctly receive the data, the base station notifies the UE to retransmit the data, and the UE determines whether the maximum number of retransmissions of the RLC layer is reached, if When the maximum number of times is reached, it can be determined that the link failure belongs to the uplink RLC layer transmission problem.
- Step 302 determining whether the measurement report is triggered; performing step 303 if the measurement report is triggered, otherwise performing step 307;
- Step 303 when it is determined in step 302 that the measurement report is triggered, the UE may further determine whether the measurement report is successfully sent. If the sending is successful, step 304 is performed, otherwise step 311 is performed;
- the UE after the UE sends the measurement report, it receives an acknowledgement message (acknowledgement) returned from the network side, and can determine that the measurement report is successfully sent.
- acknowledgement acknowledgement
- Step 304 in step 303, determining that the measurement report is successfully sent, further determining whether the handover complete message is successfully sent, and performing step 305 if the handover complete message is not successfully sent, otherwise returning to step 302;
- the handover complete message is the last message completed by the handover process, and is sent from the UE to the target base station, for example, may be an RRC connection reconfiguration complete message.
- Step 305 in step 304, in the case that it is determined that the handover complete message is not successfully sent, it may be determined that the cause of the link failure is a handover configuration problem;
- the handover configuration problem may be determined; specifically, the handover parameter problem may be the handover parameter of the UE for the target cell (eg, cell-specific offset CelllndividualOffset, see TS36) 331) If the setting is too large, the signal of the target cell is weak when the UE switches to the target cell, and the link failure may not be completed after the handover or the handover is completed.
- the handover parameter problem may be the handover parameter of the UE for the target cell (eg, cell-specific offset CelllndividualOffset, see TS36) 331) If the setting is too large, the signal of the target cell is weak when the UE switches to the target cell, and the link failure may not be completed after the handover or the handover is completed.
- Step 306 The UE records the analysis result.
- the UE may record the analysis result "switching configuration problem" in this case in the link failure report, and transmit the report to the network side through the report, but the present invention is not limited to this case, and the analysis may be performed.

- Step 307 In step 302, if it is determined that the measurement report is not triggered, the UE further determines whether there is a neighboring cell with better signal quality. If the determination result is yes, step 315 is performed; otherwise, step 308 is performed.
- Step 308 in step 307, when the determination result is no, the UE further determines whether there is a recent successful downlink transmission, if the determination result is yes, then step 309 is performed, otherwise step 313 is performed;
- the recent successful downlink transmission refers to: A successful downlink transmission occurs before it is determined that the link failure is an RLC transmission problem.
- Step 310 The UE records the analysis result.

- the analysis result may be recorded as follows: coverage hole (uplink RLC transmission problem; untriggered measurement report; no neighboring cell with good signal quality; recently successful downlink transmission) ) ";
- untriggered measurement report; no neighboring cell with good signal quality; there is a recent successful downlink transmission is optional information, and may not be recorded.
- Step 311 in step 303, when the determination result is no, the UE determines that the cause of the link failure is a handover configuration problem;
- the handover parameter problem may be that the handover parameter of the UE for the target cell (such as the cell-specific offset CelllndividualOffset, see TS36.331) is set too small, resulting in the UE receiving the service.
- the handover parameter of the UE for the target cell such as the cell-specific offset CelllndividualOffset, see TS36.331

- Step 314 the UE records the analysis result
- the UE may record the analysis result "coverage hole” in this case in the link failure report, and transmit the report to the network side through the report, but is not limited to this case, and the analysis result may also be Recorded separately and transmitted to the network side, for the network side to analyze the cause of the link failure or to optimize the network;
- the analysis result may be recorded as follows: coverage hole (uplink RLC transmission problem; untriggered measurement report; no good neighboring cell; no recent successful downlink transmission) ) ";
- no trigger measurement report is optional information, and may not be recorded.
- Step 315 in step 307, when the determination result is yes, the UE determines that the cause of the link failure is a handover configuration problem
- the handover configuration problem may be that the handover parameter of the UE for the target cell (such as the cell-specific offset Cel l lndividualOffset, see TS36.331) is set too small, so that the UE is in the received serving cell. When the signal is weak, the UE has not completed the handover.
