technical field

The present disclosure relates to the field of communication technology, and in particular, to an information processing method, device and readable storage medium.

Background technique

Conditional switching is introduced in the related art. The overall idea of conditional switching is: the network side sends a synchronous reconfiguration message to the terminal in advance, and after the terminal receives the conditional synchronous reconfiguration message, it first stores the configuration in the synchronous reconfiguration message until it meets the conditions configured in the synchronous reconfiguration message The synchronous reconfiguration process is initiated in the target cell. A conditional synchronous reconfiguration message can be used for synchronous reconfiguration of one or more target cells.

In the case where multiple cells are configured for conditional handover, there may be one or more candidate target cells that meet the synchronous reconfiguration triggering condition, and the terminal will select a candidate target cell to initiate the synchronous reconfiguration process. If access to a cell fails, the terminal will trigger cell selection and reselect a target cell to try to access. In conditional handover, since multiple candidate target cells may be configured, if the reselected target cell is the configured candidate target cell, the terminal will trigger the conditional handover recovery process and try to complete the handover process on the target cell again.

In case of handover failure or radio link failure (Radio Link Failure, RLF), the terminal will record the RLF report. And provide the RLF report to the network side. After obtaining the RLF report of the terminal, the network side can perform network optimization analysis according to the RLF report. In the process of network optimization analysis, the network side conducts analysis based on the RLF report obtained each time, and it is found through research that the results of network optimization analysis may be inaccurate.

Detailed ways

The term "and/or" in the embodiments of the present disclosure describes the association relationship of associated objects, indicating that there may be three relationships, for example, A and/or B, which may mean: A exists alone, A and B exist simultaneously, and B exists alone These three situations. The character "/" generally indicates that the contextual objects are an "or" relationship.

The term "plurality" in the embodiments of the present disclosure refers to two or more, and other quantifiers are similar.

The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

In related technologies, when the current condition switching fails, the following three scenarios may occur:

As shown in Figure 1, in Scenario 1, a conditional handover fails from the source base station to the target base station, and the process may include:

Step 101: The user equipment (User Equipment, UE) triggers a conditional handover failure from the source base station to the target base station;

Step 102: UE records the first RLF report;

Step 103: UE performs cell selection, for example, selects a cell under another base station 1, which is one of the conditional handover candidate cells, and the UE performs conditional handover recovery in this cell successfully;

Step 104: other base station 1 acquires the first RLF report recorded by the UE;

Step 105: A radio link failure occurs in a cell under another base station 1; the UE records the second RLF report;

Step 106: The UE sends a radio resource control (Radio Resource Control, RRC) connection re-establishment message, successfully re-establishes and accesses the cell under other base station 2, and triggers other base station 2 to obtain the second RLF report recorded by the UE;

Step 107: other base stations 2 send the second RLF report to the base station where RLF occurs through a failure indication (failure indication) message, that is, to other base stations 1;

Step 108: The other base station 1 analyzes the second RLF report, and sends a message (handover report message or failure indication) to notify the source base station if handover parameters need to be optimized.

The first RLF report and the second RLF report mentioned above both refer to the same type of RLF report.

When the conditional handover recovery is successful in step 103, the other base station 1 receives the RRC connection reconfiguration complete message sent by the UE, in which the UE is notified that the first RLF report is stored. The other base station 2 sends a UE information request message to the UE, and the UE sends the first RLF report to the other base station 2 through a UE information response message. The UE side clears the previously recorded first RLF report. If there is no further wireless link failure within a short period of time, that is, step 105 does not occur, according to the conditional handover failure judgment basis, it should be a conditional handover to the wrong cell failure type, that is, the conditional handover configuration parameters should be optimized to ensure In the second handover, the cell under other base station 1 is preferentially selected instead of the original handover target cell.

If a radio link failure occurs within a short period of time, that is, steps 105 and 106 occur, after receiving the message in step 107, other base stations 1 will continue to analyze the newly received second RLF report. Because in step 104, other base stations 1 obtained the first RLF report of the UE, and the UE cleared the recorded first RLF report, that is, the content of the first RLF report has been cleared, and in the second RLF report received in step 107 It only contains records related to wireless link failure, and the information is incomplete. However, other base stations 1 cannot know the relationship between the two RLF reports. In fact, both the first RLF report and the second RLF report are generated during a condition switching failure process. Therefore, if one report is used alone, analysis errors or incomplete information will result.

After the radio link failure occurs in step 105, there may be multiple possibilities, including UE initiates RRC connection re-establishment to the source base station, UE does not trigger RRC connection re-establishment but initiates RRC connection re-establishment to re-connect to a base station, etc. In any case, after the UE re-accesses the network, the network can obtain the stored second RLF report and send it to other base stations 1 for analysis.

As shown in Figure 2, in Scenario 2, the conditional handover command is sent to the UE, but at the UE side, the conditional handover is not triggered because the conditional handover trigger condition is not met, the base station sends a traditional handover command to the UE, and the UE performs Traditional handover fails to access the target cell. The difference from the process shown in Figure 1 is that in step 201, the conditional handover command is sent to the UE, but at the UE side, the execution of the conditional handover is not triggered because the conditional handover trigger condition is not met, and the base station sends a traditional handover command For the UE, the UE fails to perform traditional handover to access the target cell. Wherein, for steps 202 to 208, reference may be made to the description of steps 102 to 108 above.

As shown in FIG. 3 , in scenario 3, the conditional handover command is sent to the UE, but the UE does not trigger the execution of the conditional handover because the trigger condition of the conditional handover is not met, and RLF occurs at this time. Wherein, for steps 302 to 308, reference may be made to the description of steps 102 to 108 above.

It can be seen from the above that when the network device performs network performance analysis, the network device can only refer to the first RLF report or the second RLF report, but in fact both the first RLF report and the second RLF report fail to There is a certain correlation between the two, so the network performance analysis method of the related technology may lead to inaccurate network performance analysis results.

In order to solve the above problems, the embodiments of the present disclosure provide an information processing method and device, so as to improve the accuracy of network optimization analysis results.

Among them, the method and the device are conceived based on the same application. Since the principle of solving problems of the method and the device is similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

Referring to FIG. 4, FIG. 4 is a flowchart of an information processing method provided by an embodiment of the present disclosure. As shown in FIG. 4, it includes the following steps:

In step 401, if conditional handover failure or radio link failure occurs after conditional handover is triggered, the terminal obtains a first radio link failure RLF report, and performs conditional handover recovery.

Step 402: If the radio link fails after the conditional handover recovery succeeds, the terminal acquires a second RLF report.

Wherein, the implementation principles of step 401 and step 402 may be the same as those in related technologies.

Step 403, the terminal associates the first RLF report with the second RLF report, and obtains an association result.

Step 404, the terminal sends the association result to the network device.

In the embodiment of the present disclosure, in step 403, if the second RLF report is obtained within the first preset time, the terminal associates the first RLF report with the second RLF report, The correlated first RLF report and the second RLF report are obtained. Wherein, the first preset time can be set as required.

If the second RLF report is not obtained within the first preset time, it may be that the terminal has not obtained the second RLF report, or the second RLF report may be obtained after the first preset time. If not obtained, only the first RLF report may be sent to the network device, or other processing may not be performed. If the second RLF report is obtained after the first preset interval, the terminal may send the first RLF report and the second RLF report to the network device separately, or may also send the second RLF report and the first RLF report After association, it is sent to the network device.

Here, the purpose of setting the first preset time is to ensure whether the two RLF reports have a strong correlation, especially the two RLF reports generated before and after the conditional switching recovery operation is performed. In practical applications, the first preset time may not be set, then, after acquiring the second RFL report, the terminal associates it with the first RLF report.

In the first manner, after obtaining the first RLF report, the terminal determines to suspend sending the first RLF report to the network device, and stores the first RLF report. If the second RLF report is not obtained within the first preset time, the terminal sends the first RLF report and the second RLF report to the network device respectively, or, if the If the second RLF report is not obtained within a first preset time, the terminal sends the first RLF report to the network device.

In related technologies, since the network device triggers the information request process of the terminal after the conditional handover recovery is successful, the terminal will clear the first RLF report after sending the first RLF report to the network device, making it impossible to associate the subsequent RLF report. Two RLF reports. Therefore, in the embodiment of the present disclosure, in order to avoid this problem, the terminal can continue to store the first RLF report for a period of time after the conditional handover recovery is successful, so as to be compatible with the second RLF report generated by subsequent radio link failure to associate.

That is, in the embodiment of the application, the terminal does not immediately send the first RLF report to the network device after receiving the trigger, but suspends sending the first RLF report to it. Meanwhile, in order for the network device to determine a subsequent processing manner, the terminal may further send a first indication to the network device, where the first indication is used to instruct the network device to delay obtaining the first RLF report.

In a specific application, the terminal temporarily no longer instructs the network side to acquire the RLF report in the RRC connection reconfiguration complete message sent to the network device after the conditional handover recovery is successful. Afterwards, the terminal starts a timer, delays for a period of time, and then notifies the network device to obtain the first RLF report after the timer expires. In this way, if a radio link failure occurs before the timer expires, the terminal can associate the second RLF report with the first RLF report, for example, record two RLF reports into one RLF report and send it to the network equipment. Wherein, the time length of the timer is the above-mentioned first preset time, which can be set as required. After the timer expires, the terminal may instruct the network device to obtain the first RLF report. For example, the terminal can send a dedicated signaling message to the network device, such as an RRC connection establishment complete message, an RRC connection reconfiguration complete message, an RRC connection re-establishment complete message or an RRC recovery complete message; of course, a newly added signaling message can also be used The network device is instructed to obtain the first RLF report.

In the second manner of the embodiment of the present disclosure, after the terminal obtains the first radio link failure RLF report, the terminal sends the first RLF report to the network device and stores the first RLF report Report. If the second RLF report is not obtained within the first preset time, the terminal deletes the first RLF report.

In this way, the terminal sends the first RLF report to the network device in response to the information request process triggered by the network device after the conditional handover recovery is successful, and at the same time, the terminal stores the first RLF report Report. The terminal may start a timer. If the second RLF report is received before the timer expires, the terminal combines the first RLF report and the second RLF report. In this case, in order to facilitate network equipment to better perform network performance optimization analysis and improve the accuracy of its analysis results, the terminal sends a second indication to the network equipment, and the second indication is used to send the The network device indicates that the first RLF report is the first RLF report that has been sent. Then, when analyzing the network performance, the network device may determine that the first RLF report is an already analyzed RLF report, so as to correct the analysis result.

Wherein, the second indication may be an identification bit added in the combined first RLF report and the second RLF report, to indicate that the first RLF report has been sent to the network device separately. Alternatively, the second indication may also be sent to the network device separately.

In practical applications, the terminal instructs the network device to acquire the first RLF report in the RRC connection reconfiguration complete message sent to the network device after the conditional handover recovery is successful. The terminal starts the timer. Wherein, the time length of the timer is the above-mentioned first preset time, which can be set as required. Before the timer expires, if the terminal receives a request from the network device for obtaining the first RLF report, the terminal sends the first RLF report to the network device. Meanwhile, the terminal continues to store the first RLF report A. If no radio link failure occurs before the timer expires, the terminal cannot obtain the second RLF report, and the terminal will delete the first RLF report; if a radio link failure occurs before the timer expires, the terminal obtains the second RLF report, and The first RLF report and the second RLF report are correlated.

In the above two manners, the manner of associating the first RLF report with the second RLF report is that the terminal combines the first RLF report and the second RLF report to obtain the associated first RLF report and a second RLF report. For example, the two reports may be combined into one RLF report; or, the first RLF report and the second RLF report are still mutually independent reports in content, but are sent to the network side device through a message.

In the third mode of the embodiment of the present disclosure, the terminal includes the first association identifier in the first RLF report and/or includes the second association identifier in the second RLF report, and the first association The identifier and/or the second association identifier is used to indicate that there is an association between the first RLF report and the second RLF report.

That is, the terminal may include an association identifier in one or both of the first RLF report and the second RLF report, to indicate that there is an association between the two. Wherein, the first association identifier or the second association identifier may be implemented in any of the following forms:

A. Time related identifiers, such as time node information. For example, the associated time node information can be added in the first RLF report and the second RLF report to indicate the relevance, such as the acquisition time of the first RLF report, the acquisition time of the second RLF report, and then determine different RLF reports by time connection between.

B. Index class associated identifier. It may also be UE identity related information, such as UE-related index information. For example, a UE-related index may be added to the first RLF report and the second RLF report to indicate the correlation between different RLF reports.

C. Association identifiers in preset forms, such as randomly generated values, etc. For example, other forms of association information are included in the first RLF report and the second RLF report to indicate the association of the two RLF reports.

In addition, the second RLF report may also include first information, and the first information is used to indicate the length of time from the conditional handover recovery success to the radio link failure, so that the network device can better perform network optimization analyze. Wherein, the first information may be added during obtaining the second RLF report, or may be added during the process of associating the first RLF report with the second RLF report.

In step 404, for the first two methods, the terminal may directly send the association result to the network device. In the above-mentioned third way, according to different ways included in the association identifier, the terminal may send the association result to the network device in at least the following ways:

In the embodiment of the present disclosure, when conditional handover failure or wireless link failure occurs after conditional handover is triggered, the terminal associates the first RLF report with the second RLF report, and sends the association result to the network device. Therefore, using the solution of the embodiment of the present disclosure, the network device can perform network optimization analysis in combination with the first RLF report and the second RLF report, thereby improving the accuracy of the network optimization analysis result.

Referring to FIG. 5, FIG. 5 is a flowchart of an information processing method provided by an embodiment of the present disclosure. As shown in FIG. 5, it includes the following steps:

Step 501, the network device acquires the association result sent by the terminal.

Wherein, the first RLF report is recorded by the terminal when a conditional handover failure or radio link failure occurs after the conditional handover is triggered, and the second RLF report is recorded by the terminal when the conditional handover recovery is successful It is logged in the event of a subsequent wireless link failure.

Step 502, the network device performs network performance analysis according to the association result.

Wherein, the association result may be the association result obtained in the first manner and the second manner of step 401 above. Therefore, the network device can respectively obtain the first RLF report and the second RLF report from the association result, and perform network performance analysis according to the first RLF report and the second RLF report, and obtain Analyze the results. In the embodiment of the present disclosure, the network performance analysis may be Mobility Robust Optimization (MRO).

In this embodiment of the present disclosure, if the terminal does not immediately send the first RLF report to the terminal in response to the trigger of the network device, the network device may also receive the first indication sent by the terminal, and the first indication uses and instructing the network device to delay acquiring the first RLF report. Afterwards, if the terminal does not obtain the second RLF report within the first preset time, the terminal will notify the network device to obtain the first RLF report. At this point, the network device may acquire the first RLF report from the terminal.

Wherein, the association result may also be an association result obtained in the third way of step 403 above. That is, the terminal may also include the association identifier in the first RLF report and/or the second RLF report. Correspondingly, the network device receives the first RLF report or the first RLF report including the first association identifier, and receives the second RLF report or the second RLF report including the second association identifier. In this case, when the network device determines that there is an association between the first RLF report and the second RLF report according to the first association identifier and/or the second association identifier, the network device determines that there is an association between the first RLF report and the second RLF report according to The first RLF report and the second RLF report perform network performance analysis to obtain analysis results.

In this embodiment of the present disclosure, if the terminal sends the first RLF report and the association result obtained in the second manner of step 403 above, the network device may obtain the second indication sent by the terminal, and the second indication It is used to indicate to the network device that the first RLF report is the first RLF report that has been sent, and adjust the analysis result according to the second indication.

In addition, on the basis of the above-mentioned embodiments, the second RLF report includes first information, and the first information is used to indicate the time length from when the conditional handover recovers successfully to when the radio link fails. Then, the network device may perform network performance analysis on the first RLF report and the second RLF report according to the first information, and obtain an analysis result. For example, if the first information indicates that the time length is relatively short, it indicates that there is a problem with the success of condition recovery; if the first information indicates that the time length is relatively long, it indicates that the condition recovery is successful, and a wireless link failure occurs subsequently.

Referring to FIG. 6, FIG. 6 is a flowchart of an information processing method provided by an embodiment of the present disclosure. As shown in FIG. 6, it includes the following steps:

Step 601, the first network device acquires the first RLF report and the second RLF report.

Step 602. The first network device associates the first RLF report with the second RLF report to obtain an association result.

In practical applications, if the obtained first RLF report and the second RLF report are carried in the same message, the first network device sends the first RLF report and the second RLF report performing association to obtain an association result; and/or, the first network device associates the first RLF report with the second RLF report by using the association identifier carried in the RLF report to obtain an association result.

That is to say, in this embodiment of the present disclosure, only when it is determined that the first RLF report and the second RLF report are carried in the same message, the first network device sends the first RLF report and the The second RLF report is correlated. The first network device may also determine to associate the first RLF report with the second RLF report by using the association identifier carried in the RLF report. For example, the first network device may determine whether the association identifiers carried in the two RLF reports indicate that the two RLF reports are associated. If there is an association, the first network device associates the first RLF report with the second RLF report.

Time class association identifier;

Index class association identifier;

Association ID in default form.

In this step, the first network device may associate the first RLF report with the second RLF report in at least two ways as follows.

Manner 1: The first network device determines to suspend sending the first RLF report to the second network device, and stores the first RLF report. If the first network device obtains the second RLF report within a second preset time, the first network device associates the first RLF report with the second RLF report to obtain the associated The first RLF report and the second RLF report.

According to related technologies, after the first network device receives the first RLF report, it needs to send a failure indication (failure indication) message to the source base station, and the source base station analyzes the first RLF report for parameter optimization. However, in the embodiment of the present disclosure, in order to perform analysis in conjunction with subsequent RLF reports, the first network device suspends sending the first RLF report to the second network device, and stores the first RLF report. At this time, the first network device may set a timer. Wherein, the time length of the timer is the same as that of the second preset time, which can be set as required. If the first network device obtains the second RLF report before the timer expires, the first network device associates the first RLF report with the second RLF report to obtain the associated first RLF report and second RLF report. If the first network device does not obtain the second RLF report before the timer expires, the first network device sends the first RLF report to the second network device through a failure indication message.

For example, the first network device starts timer one after receiving the RLF report. If a radio link failure occurs before timer one expires, timer one is stopped, the first RLF report is continuously stored, and timer two is started at the same time. Before timer 2 expires, if the first network device receives the second RLF report, stop timer 2, and send a failure indication message to the second network device after combining the first RLF report and the second RLF. In this case, the failure indication message needs to be extended so that it can carry the merged first RLF report and the second RLF report. If the second RLF report is not received before the timer 2 times out, the first network device sends the first RLF report to the second network device through a failure indication message.

In the first way, the way of associating the first RLF report with the second RLF report is that the first RLF report and the second RLF report are combined to obtain the associated first RLF report and the second RLF report Report. For example, the two reports can be combined into one RLF report; or, the first RLF report and the second RLF report are still independent reports in content, but are represented by one RLF report.

Mode 2: The first network device includes the third association identifier in the first RLF report, and stores the third association identifier. If the first network device obtains the second RLF report within a third preset time, the first network device includes the third association identifier in the second RLF report.

After the first network device receives the first RLF report, it needs to send a failure indication message (carrying the first RLF report) to the second network device, and at the same time, include the third association identifier in the first RLF report, and store the first RLF report Three associated logos. At this time, the first network device may set a timer. Wherein, the time length of the timer is the same as that of the third preset time, which can be set as required. If the first network device obtains the second RLF report before the timer expires, include the third association identifier in the second RLF report, for example, in a failure indication message and/or a handover report (HANDOVER REPORT ) message includes the third association identifier, and sends the second RLF report including the third association identifier through a failure indication message and/or HANDOVER REPORT. If the first network device does not obtain the second RLF report before the timer expires, the first network device deletes the third association identifier.

For example, after receiving the RLF report, the first network device sends it to the second network device, and starts timer one. If a radio link failure occurs before timer one expires, stop timer one and continue to store the third association identifier. At the same time, start timer two. Before timer two expires, if the first network device receives the second RLF report, stop timer two, include the third association identifier in the second RLF report, and send it to the second network device. If the second RLF report is not received before the timer two expires, the first network device deletes the third association identifier.

Wherein, the third association identifier can be implemented in any of the following forms:

A. Time class association identification: such as time node information, adding associated time node information in the first RLF report and the second RLF report to indicate association;

B. Index class association identification: it can also be UE identification class association information, such as UE-related index information, and the associated UE index is added in the first RLF report and the second RLF report to indicate association;

C. Association identifier in a preset form: for example, a randomly generated numerical value, etc., adding the same random numerical value to the first RLF report and the second RLF report respectively to indicate association.

Step 603, the first network device sends the association result to the second network device.

In the first manner of step 602, the first network device may directly send the association result to the second network device. In the second method of step 602 above, the first network device sends to the second network device the first RLF report containing the third association identifier, and sends the second network device containing the The second RLF report of the third association identifier.

In the embodiment of the present disclosure, when conditional handover failure or radio link failure occurs after conditional handover is triggered, the first network device associates the first RLF report with the second RLF report, and sends the Associated results. Therefore, using the solutions of the embodiments of the present disclosure, the second network device can perform network optimization analysis in combination with the first RLF report and the second RLF report, thereby improving the accuracy of the network optimization analysis result.

Referring to FIG. 7, FIG. 7 is a flowchart of an information processing method provided by an embodiment of the present disclosure. As shown in FIG. 7, it includes the following steps:

Step 701, the second network device acquires the association result sent by the first network device.

Wherein, the association result is obtained by the first network device associating the first RLF report with the second RLF report; the first RLF report is obtained by the conditional handover failure of the terminal after the conditional handover is triggered or the wireless link It is recorded in the case of a failure, and the second RLF report is recorded by the terminal in the case of a radio link failure after performing conditional handover recovery successfully.

Step 702, the second network device performs network performance analysis according to the association result.

Wherein, the association result includes the first RLF report and the second RLF report. Here, the second network device may separately obtain the first RLF report and the second RLF report from the association result, and perform network performance based on the first RLF report and the second RLF report. Analyze and get the analysis results. In the embodiment of the present disclosure, network performance analysis may be MRO.

Wherein, the association result includes the first RLF report including the third association identifier and the second RLF report including the third association identifier. Here, the second network device respectively acquires the first RLF report including the third association identifier and the second RLF report including the third association identifier.
