[0050] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0051] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0052] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.
[0053] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.
[0054] A new research project on 5G technical standards was approved at the RAN#80 plenary meeting of the 3rd Generation Partnership Project (3GPP). One of the research objectives of this project is to find a solution to meet one of the mobility requirements in the New Radio (NR): seamless switching, that is, being able to meet a switching interruption time of 0 milliseconds during the cell switching process. Among the solutions being studied to reduce the switching interruption time, there is a solution called Fast Handover Failure Recovery, which is to quickly recover the wireless link connection between the user equipment (UE) and the network-side base station from a failed or predicted failed handover during the handover process.
[0055] Among them, the fast switching failure recovery solution in the NR system will be studied based on the fast switching failure recovery solution in the Long Term Evolution (LTE) system.
[0056] The current fast switching failure recovery solution can be implemented by configuring the T312 timer (Timer 312). The configuration and startup process of the T312 timer in the related art is as follows:
[0057] 1. After the UE enters the connected state, the network will configure the T312 timer for event-triggered measurements. The start conditions of the T312 timer are as follows:
[0058] (a) The UE detects a radio link failure (RLF) and starts the T310 timer (Timer310).
[0059] (b) The measurement configured with the T312 timer triggers the measurement report. The triggering modes are as follows:
[0060] (1) The first cell triggers the event, that is, the corresponding measurement identifier (measId) is not yet a measurement report entry in the measurement report list (VarMeasReportList), that is, the first time a cell meets the entry conditions applied to the event within the trigger time (time to Trigger).
[0061] (2) A new trigger (a subsequent cell triggers the event) means that the corresponding measurement identifier (measId) is already a measurement report entry in the measurement report list (VarMeasReportList), and a cell meets the entry conditions applied to the event within the trigger time, and the information of the cell is not recorded in the cell trigger list. In other words, a new cell (not the first cell) meets the entry conditions applied to the event within the trigger time.
[0062] (c) If the T310 timer is running, start the T312 timer.
[0063] 2. Due to the reasons of the radio link, the uplink measurement report or the downlink reconfiguration message may not reach the destination smoothly, so the T312 timer times out, and the UE will trigger RRC (Radio Resource Control) reconstruction. Usually, the duration of the T312 timer is shorter than the T310 timer, so as to achieve the purpose of rapid recovery of the radio link.
[0064] Further, Figure 1 FIG. 1 is a flow chart of a rapid recovery process of a wireless link in the related art. Figure 1 As shown, the UE receives measurement configuration information, including configuration information of the T312 timer (S1), the UE detects RLF and starts the T310 timer (S2), and the measurement configured with the T312 timer triggers a measurement report (the first trigger or a new trigger), that is, the measurement report of the first cell corresponding to the event configured with the T312 timer is triggered (S3), the T312 timer is started (S4), the T312 timer times out (S5), and the RRC connection reestablishment is triggered (S6).
[0065] Accordingly, Figure 2 FIG. 1 is another flow chart of wireless link rapid recovery in the related art. Figure 2 As shown, after configuring the T312 timer, if the UE detects RLF, the T310 timer is started. When the measurement configured with the T312 timer triggers a measurement report, if the T310 timer is running, the T312 timer can be started. When the T312 timer expires, the RRC connection reestablishment is triggered.
[0066] Figure 3 FIG. 1 is a schematic diagram of a cell switching in the related art. Figure 3As shown, the UE can configure the T312 timer through the received measurement configuration information, and can start the T310 timer after detecting the radio link failure RLF. When the T310 timer is running, if the measurement configured to start the T312 timer triggers the measurement report, the T312 timer is started. If the T312 timer times out, the switching failure is declared, and the reconstruction speed is accelerated before the T310 timer times out, the RRC connection reconstruction is triggered, and the reconstruction and configuration of the RRC are completed.
[0067] It can be seen that, on the one hand, when starting the T312 timer, only the case where the T310 timer is started first and the event-type measurement configured with the T312 timer is triggered is considered, while the case where the event-type measurement report configured with the T312 timer is triggered first and the T310 timer is started is not considered, that is, the execution order of the two steps S2 and S3 in the above figure cannot be exchanged. However, in actual processes, the following scenarios are often encountered:
[0068] When cell 1, as the first cell or a new cell, meets the entry conditions for event 1 within the trigger time (time to Trigger), if the T310 timer is not started, the T312 timer cannot be started when the T312 timer is configured for event 1. However, since cell 1 will send a measurement report to the network side, the information of cell 1 needs to be recorded in the cell trigger list. Afterwards, if the number of measurement report transmissions of cell 1 does not reach the preset number threshold, cell 1 may trigger the measurement report of event 1 again. At this time, if the T310 timer is already running, but since cell 1 is an old cell, that is, it has been recorded in the cell trigger list, it does not meet the above-mentioned conditions for triggering the T312 timer, so the T312 timer cannot be started. In other words, the measurement configured with the T312 timer first meets the trigger condition, and the configured number of reports (reportAmount) is not 1, and then the T310 timer is started. Even if the measurement report is triggered again by the old cell later, the T312 timer cannot be started.
[0069] In the above situation where the T312 timer cannot be started, the RRC connection cannot be quickly restored, which prolongs the interruption time and reduces the communication performance of the UE.
[0070] In response to the above problems, an embodiment of the present application provides a method for rapid recovery of a wireless link, which specifically comprises: configuring a first timer according to measurement configuration information; if the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, when the measurement report of the first cell is triggered while the second timer is running, the first timer is started; wherein the second timer is a timer that is started when a wireless link failure is detected; if the first timer times out, RRC connection reconstruction is triggered. In this way, in an embodiment of the present application, when the first timer of the first cell is not started, even if the information of the first cell has been recorded in the cell trigger list, the first timer can still be started when the measurement report of the first cell is triggered when the second timer is running, thereby overcoming the defect that the wireless link cannot be quickly recovered in certain scenarios, shortening the time of wireless link interruption, and improving the communication performance of the user equipment. The following is a detailed description.
[0071] It should be noted that the wireless link rapid recovery method provided in the embodiment of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), LTE system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system or 5G system, etc.
[0072] For example, in the embodiments of the present application, Figure 4 is a schematic diagram of a communication system, such as Figure 4As shown, the communication system 100 may include a network device 110, which may be a device that communicates with a user equipment UE100 (or referred to as a communication terminal, terminal, or terminal device).

[0080] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0081] See also Figure 5 , is a flow chart of a method for rapid recovery of a wireless link provided in an embodiment of the present application. Figure 5 As shown, the method includes:
[0082] Step S501: configure a first timer according to measurement configuration information.
[0083] The measurement configuration information records configuration information of the first timer, for example, the timing duration of the first timer.
[0084] In this embodiment of the present application, the user equipment may configure the first timer according to the received measurement configuration information.
[0085] As a possible implementation manner, the first timer may be a T312 timer.
[0086] It should be noted that in the embodiment of the present application, the measurement configuration information may be sent by the network device to the user equipment. The network device may correspond to the serving cell. The serving cell may be a PCell in an LTE system, a PCell in an NR system, a PSCell in an LTE system, or a PSCell in an NR system.
[0087] Step S502: If the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, when the measurement report of the first cell is triggered while the second timer is running, the first timer is started.
[0088] The second timer is a timer started when a radio link failure is detected.
[0089] In an embodiment of the present application, after the user equipment configures the first timer according to the measurement configuration information, if the first cell is the first cell that satisfies the entry condition applied to a certain event within the trigger time (time to Trigger), or the first cell is a new cell that satisfies the entry condition applied to a certain event within the trigger time (time to Trigger), because the second timer is not started, when the first timer is used in the event, the user equipment cannot start the first timer. Since the measurement report of the first cell has been triggered, that is, the user equipment needs to send the measurement report of the first cell to the network side, the user equipment needs to record the first cell in the cell trigger list. In other words, if the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, it means that the measurement report of the first cell has been triggered and the first timer was not started when the measurement report was triggered, that is, the first cell is an old cell where the measurement report is triggered, and the first timer of the first cell has not been started. When the user equipment detects that the measurement report of the first cell is triggered again while the second timer is running, the user equipment can start the first timer to shorten the wireless link interruption time of the user equipment and achieve the purpose of rapid recovery of the wireless link.
[0090] In some embodiments, after configuring the first timer according to the measurement configuration information, the user equipment may start the second timer if a radio link failure is detected.
[0091] In some embodiments, the second timer comprises a T310 timer.
[0092] As a possible implementation manner, the duration of the second timer is greater than the duration of the first timer, so as to shorten the radio link interruption time of the user equipment and achieve the purpose of rapid recovery of the radio link.
[0093] Step S503: If the first timer times out, RRC connection reestablishment is triggered.
[0094] In the embodiment of the present application, after the user equipment starts the first timer, since the duration of the first timer is less than the duration of the second timer, generally, the first timer may have timed out while the second timer is running. When the first timer times out, the user equipment may re-trigger the RRC connection reestablishment.
[0095] In this way, for the case where the measurement report corresponding to the event configured with the first timer is triggered first and the second timer is started later, in an embodiment of the present application, the first timer can also be started, which can trigger the RRC reconstruction process in advance, shorten the wireless link interruption time of the user equipment, and achieve the purpose of rapid recovery of the wireless link.
[0096] For example, Figure 6 FIG. 1 is a schematic diagram of a scenario in which a wireless link cannot be quickly restored in the related art. Figure 6 As shown, assuming that the first timer is a T312 timer and the second timer is a T310 timer, the relevant technology requires that when the measurement report of the first cell or new cell corresponding to the event configured with the T312 timer is triggered after the T310 timer runs, that is, when the measurement configured with the T312 timer triggers the measurement report, the T312 timer is started. Therefore, before the T310 timer is started, if the measurement report of the first cell or new cell corresponding to the event configured with the T312 timer is triggered first, the T312 timer of the cell cannot be started after the T310 timer runs, and the radio link cannot be quickly recovered through the T312 timer. The user equipment can re-trigger the RRC connection reconstruction until the T310 timer times out.
[0097] Figure 7 FIG. 1 is a schematic diagram of a scenario of rapid recovery of a wireless link in an embodiment of the present application. Figure 7 As shown, before the T310 timer is started, if the measurement report of the first cell corresponding to the event configured with the T312 timer has been triggered, that is, the measurement configured with the T312 timer has triggered the measurement report, that is, the information of the first cell has been recorded in the cell trigger list and the first timer corresponding to the first cell has not been started, after the wireless link failure is detected, if the measurement report of the first cell is triggered again, the T312 timer can be started. After the T312 timer expires, the user equipment triggers RRC reconstruction, and the wireless link can be quickly restored through the T312 timer.
[0098] In contrast, the wireless link rapid recovery method proposed in the embodiment of the present application, even if the information of the first cell has been recorded in the cell trigger list, as long as the first timer has not been started, when the measurement report of the first cell is triggered again if the T310 timer is running, the first timer can still be started, thereby realizing the early triggering of the RRC connection reconstruction process.
[0099] As a possible implementation method, Figure 8 As shown, the method also includes:
[0100] Step S504: If the information of the first cell is not recorded in the cell trigger list and the measurement report of the first cell is triggered, Sure Whether the second timer is turned on.
[0101] In an embodiment of the present application, if the information of the first cell is not recorded in the cell trigger list, it means that the measurement report of the first cell has not been triggered. When the measurement report of the first cell is triggered, it means that the first cell is the first cell or a new cell that meets the entry condition of a certain event within the trigger time. At this time, before starting the first timer corresponding to the event, it is necessary to determine whether the second timer is turned on. The user equipment can detect whether the second timer is running.
[0102] The user equipment performs different steps according to different determination results: When it is determined that the second timer is not started, the user equipment performs step S505a; when it is determined that the second timer is started, the user equipment performs step S505b.
[0103] Step S505a: If the second timer is not started, the information of the first cell is recorded in the cell trigger list and the first timer is not started, and the measurement report of the first cell is sent to the network side.
[0104] In the embodiment of the present application, when the user equipment determines that the second timer is not started, it indicates that the first timer cannot be started. At this time, the user equipment can record the information of the first cell in the cell trigger list, so as to send the obtained measurement report of the first cell to the network side according to the cell trigger list. And, since the second timer is not started, the user equipment does not start the first timer.
[0105] At this time, in the above step S502, if the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, when the second timer is running and the measurement report of the first cell is triggered, then starting the first timer includes: if the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, when the second timer is running and the measurement report of the first cell is triggered again, then starting the first timer.
[0106] That is, in the above step S504, the measurement report of the first cell has been triggered, but the first timer has not been started because the second timer is not running, and the user equipment has recorded the information of the first cell in the cell trigger list. In the subsequent process, if the measurement report of the first cell is triggered again and the second timer is running, the user equipment can start the first timer.
[0107] Step S505b: If the second timer is started, the user equipment starts the first timer.
[0108] That is, after the user determines that the second timer is started, when the measurement report of the first cell is triggered, the first timer associated with the measurement report can be started, and the user equipment starts the first timer.
[0109] As a possible implementation, Fig. 9 As shown, the above method also includes:
[0110] Step S506: Receive report configuration information and measurement configuration information.
[0111] The report configuration information includes entry condition information of the event at the first frequency point, identification information of the event, and timer information for indicating whether to use the first timer in the event; the measurement configuration information includes information of configuration parameters of the first timer. The first cell is located in the first frequency point.
[0112] In an embodiment of the present application, the network side may configure the entry condition information of the event that triggers the measurement report, the identification information of the event, and the timer information for indicating whether the event uses the first timer for different frequency points, and send the entry condition information of the event that configures the measurement report for different frequency points, the identification information of the event, and the timer information for indicating whether the event uses the first timer as the content of the report configuration information to the user equipment. The user equipment may receive the report configuration information sent by the network side, and the report configuration information includes the entry condition information of the event at the first frequency point, the identification information of the event, and the timer information for indicating whether the first timer is used in the event. In some embodiments, the event may be an A3 event.
[0113] It should be understood that the network side sets different entry condition information for events that trigger measurement reports for different frequency points. When each cell in the frequency point meets the entry condition of the event at the frequency point, the cell will be triggered to perform signal measurement and send a measurement report to the network side. Since the report configuration information includes timer information, the user equipment can know whether the event uses the first timer according to the timer information. When the event uses the first timer, when the cell meets the entry condition of the event at the frequency point, if the second timer is running, the first timer can be started.
[0114] The network side can set configuration parameters such as the timing duration of the first timer according to actual needs, and send the configuration parameter information as measurement configuration information to the user equipment. The user equipment receives the measurement configuration information and can configure the first timer according to the measurement configuration information.
[0115] Step S507: Based on the report configuration information, measure the cells within the first frequency point.
[0116] In an embodiment of the present application, after receiving the report configuration information, the user equipment can determine the entry condition information of the event of each frequency point, the identification information of the event, and the timer information used to indicate whether to use the first timer in the event by parsing the report configuration information. In this way, the user equipment can measure the cells within the first frequency point and detect whether the measurement results of each cell within the first frequency point meet the entry conditions of the event of the first frequency point. That is, the user equipment can measure each cell within the first frequency point and obtain the measurement results of each cell within the first frequency point.
[0117] At this time, the measurement report of the first cell is triggered, including: the measurement result of the first cell meets the entry condition of the event.
[0118] That is, after receiving the report configuration information, the user equipment can detect the signal quality of the cell in the first frequency point according to the report configuration information, and match the measurement of the signal quality of the cell with the event entry condition information of the first frequency point. For example, the user equipment can match the measurement result of the first cell with the entry condition information of the event of the first frequency point. If the measurement result of the first cell matches the entry condition information of the event of the first frequency point, it means that the measurement result of the first cell meets the entry condition of the event, and the measurement report of the first cell can be reported to the network side. That is, the user equipment can determine that the measurement result of the first cell is triggered.
[0119] When the measurement report of the first cell is triggered and the second timer is running, if the first timer corresponding to the event is not started, the first timer may be started.
[0120] As a possible implementation, when starting the first timer, the timer information of the configuration information needs to be reported to indicate that the first timer is used in the event. If the timer information indicates that the first timer is not used in the event, when the measurement report of the first cell is triggered and the second timer is running, the user equipment cannot start the first timer. That is, in the above step S502, if the information of the first cell has been recorded in the cell trigger list and the first timer is not started, when the measurement report of the first cell is triggered while the second timer is running, starting the first timer includes:
[0121] If the information of the first cell has been recorded in the cell trigger list and the first timer has not been started, when the measurement report of the first cell is triggered while the second timer is running, and the timer information indicates to use the first timer in the event, the first timer is started.
[0122] That is, the first cell is not the first cell to meet the entry conditions of the event of the first frequency point and the first cell is not a new cell to meet the entry conditions of the event of the first frequency point, but is an old cell that meets the entry conditions of the event of the first frequency point again, that is, the information of the first cell has been recorded in the cell trigger list, and the first timer corresponding to the first cell has not been started, if it is detected that the second timer is running, the measurement report of the first cell is triggered again, that is, if it is detected that the second timer is running, the measurement result of the first cell matches the event entry condition information of the first frequency point again, at this time, when the user equipment determines that the timer information in the report configuration information indicates that the first timer is used in the event, the user equipment can start the first timer.
[0123] In some embodiments, if the information of the first cell is not recorded in the cell trigger list, it includes: the identification information of the event is not recorded in the measurement report list.
[0124] It should be noted that the measurement report list is used to record identification information of events for which measurement reports need to be sent to the network side.
[0125] In an embodiment of the present application, the first cell is the first cell in the first frequency point that meets the entry conditions of the event. Since no cell in the first frequency point has met the entry conditions of the event before, the measurement report corresponding to the event does not need to be sent to the network side, so the identification information of the event is not recorded in the measurement report list. Therefore, it is possible to determine whether the cell is the first cell in the first frequency point that meets the entry conditions of the event by detecting whether the identification information of the event is recorded in the measurement report list. When the first cell is the first cell in the first frequency point that meets the entry conditions of the event, the information of the cell is not recorded in the corresponding cell trigger list. In other words, it is possible to determine whether the information of the first cell is not recorded in the cell trigger list by determining whether the first cell is the first cell in the first frequency point that meets the entry conditions of the event. If it is determined that the identification information of the event is not recorded in the measurement report list, it means that the information of the first cell is not recorded in the cell trigger list.
[0126] It should be understood that if the identification information of the event has been recorded in the measurement report list, it does not mean that the information of the first cell has been recorded in the cell trigger list. This is because other cells at the first frequency point may meet the entry conditions of the event, so that the user equipment records the identification information of the event in the measurement report list, but the first cell has not met the entry conditions of the event before, so the information of the first cell is not recorded in the cell trigger list. The cell trigger list records the information of other cells that meet the entry conditions of the event. At this time, the user equipment needs to determine whether the information of the first cell is recorded in the cell trigger list by detecting the information recorded in the cell trigger list.
[0127] As a possible implementation, Fig.10 As shown, the above method also includes:
[0128] Step S508: Determine whether the number of times the measurement report is sent reaches a preset number.
[0129] In an embodiment of the present application, the number of times each cell sends a measurement report can be pre-set to reduce the load on the user equipment and the network side. When the measurement report of the first cell is triggered, the user equipment needs to first detect whether the number of times the measurement report is sent has reached a preset number before sending the measurement report to the network side. When the preset number is reached, the network side no longer receives the measurement report, so the user equipment does not need to send the measurement report again. Before the user equipment measures the cell in the first frequency point, it needs to first determine whether the number of times the measurement report of each cell in the first frequency point has reached a preset number. That is, the user equipment can detect whether the number of times the measurement report of the first cell has reached a preset number. The user equipment can update the number of times the measurement report is sent each time the measurement report is sent to the network side, so that the recorded number of times the measurement report is sent can be compared with the preset number to determine whether the number of times the measurement report is sent has reached the preset number.
[0130] The above-mentioned step S507 of measuring the cells in the first frequency point based on the report configuration information includes: when the number of times the measurement report is sent does not reach a preset number of times, measuring the cells in the first frequency point based on the report configuration information.
[0131] That is, during detection, the user equipment can measure the cell whose number of measurement reports sent within the first frequency point has not reached the preset number of times based on the report configuration information. When the user equipment determines that the number of measurement reports sent for the first cell has not reached the preset number of times, the first cell can be measured based on the report configuration information.
[0132] Exemplarily, the user equipment receives the report configuration information and the measurement configuration information sent by the network side. Assume that the report configuration information includes the entry condition information of event 1 in frequency point 1, the identification information of event 1 and the timer information for indicating the use of the first timer in event 1. The duration of the first timer corresponding to event 1 is recorded in the measurement configuration information. The user equipment can configure the first timer of event 1 according to the measurement configuration information. Assume that cell 1 and cell 2 are both located in the first frequency point. After the user equipment receives the report configuration information, it detects that the number of measurement report transmissions of cell 1 and cell 2 in the first frequency point is 0, which does not reach the preset number. At this time, the user equipment can measure the signal quality of cell 1 and cell 2 based on the report configuration information. The user equipment obtains the measurement result of cell 1, matches the measurement result of cell 1 with the entry condition information of event 1, and assumes that the measurement result of cell 1 matches the entry condition information of event 1. The user equipment can determine that cell 1 is the first cell in the first frequency point that meets the entry condition of event 1 by detecting that the identification information of event 1 is not recorded in the measurement report list. Assuming that the wireless link of the user equipment has not failed and the second timer has not been started, the user equipment cannot start the first timer corresponding to cell 1. The user equipment can record cell 1 in the cell trigger list and record the identification information of event 1 in the measurement report list. The user equipment sends the measurement result of cell 1 to the network side. Similarly, assuming that the measurement result of cell 2 matches the entry condition information of event 1, the user equipment can determine that cell 2 is a new cell that meets the entry condition of event 1 within the first frequency point by detecting that the identification information of event 1 has been recorded in the measurement report list and the information of cell 2 has not been recorded in the cell trigger list. Assuming that the wireless link of the user equipment has not failed and the second timer has not been started, the user equipment cannot start the first timer corresponding to cell 2. The user equipment can record cell 2 in the cell trigger list. The user equipment sends the measurement result of cell 2 to the network side.
[0133] The user equipment may periodically perform signal instruction measurements on cell 1 and cell 2. When the measurement result of cell 1 matches the entry condition information of event 1 again, the user equipment can determine that cell 1 is an old cell in the first frequency point that meets the entry condition of event 1 by detecting that the information of cell 1 has been recorded in the cell trigger list. Assuming that the radio link of the user equipment fails and the second timer has been started and is running, the user equipment can determine that the measurement report of cell 1 is triggered, and the user equipment can start the first timer corresponding to cell 1.
[0134] Similarly, when the measurement result of cell 2 matches the entry condition information of event 1 again, the user equipment can determine that cell 2 is an old cell in the first frequency point that meets the entry condition of event 1 by detecting that the information of cell 2 has been recorded in the cell trigger list. Assuming that the radio link of the user equipment fails and the second timer has been started and is running, the user equipment can determine that the measurement report of cell 2 is triggered, and the user equipment can start the first timer corresponding to cell 2.
