[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0040] The wireless link quality monitoring method provided in the embodiment of the present application can be applied in the application environment shown in FIG1. The terminal 102 communicates with the network device 104 through the network. The terminal (TE) 102 can also be referred to as the user equipment (UE), and the terminal 102 can be various mobile devices, for example, a mobile phone (or a "cellular" phone), a computer with a mobile terminal, etc., or a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device. The network device 104 may be a device for communicating with the terminal 102, for example, it may be a base station (Base TransceiverStation, referred to as "BTS") in a GSM (Global System for Mobile Communications) system or a CDMA (Code Division Multiple Access) system, or a base station (NodeB, referred to as "NB") in a WCDMA (Wideband Code Division Multiple Access) system, or an evolved base station (Evolutional Node B, referred to as "eNB" or "eNodeB") in an LTE (Long Term Evolution) system. The present application does not limit the terminal 102 and the network device 104.
[0041] In an exemplary embodiment, Figure 2 As shown, a wireless line quality monitoring method is provided, which is described by taking the method applied to the terminal 102 in FIG. 1 as an example, and includes the following steps 202 to 204. Among them:
[0042] Step 202: When the terminal is in a synchronous state and the current radio link measurement mode of the terminal is a normal measurement mode, a measurement mode corresponding to an evaluation period after the current evaluation time is determined based on a plurality of monitoring measurement values corresponding to the current evaluation time.
[0043] Among them, the synchronization state refers to the block error rate of the demodulated received signal at the receiving end being lower than a certain block error rate threshold, which can ensure that the terminal can reliably receive the data sent by the transmitting end. The out-of-sync state refers to the block error rate of the demodulated received signal at the receiving end being higher than a certain block error rate threshold, which can no longer ensure that the terminal can reliably receive the data sent by the transmitting end. The out-of-sync state may be caused by signal attenuation, delay variation, frequency offset, phase distortion, etc. during signal transmission, resulting in weak signal strength at the receiving end or signal interference by noise, thereby affecting the stability and reliability of the communication link. In wireless link quality monitoring, the synchronization state of the receiving end is usually monitored and evaluated to ensure that the communication link is in a good synchronization state, thereby ensuring reliable data transmission. When the receiving end is in an out-of-sync state, the terminal RRC (Radio Resource Control) layer needs to initiate a re-establishment process.
[0044] Among them, the wireless link measurement mode includes the wireless link quality monitoring measurement frequency, the historical monitoring cycle duration corresponding to the link quality evaluation and the monitoring measurement value data set size; among them, exemplarily, the monitoring measurement value data set is implemented using a data buffer area.
[0045] In this embodiment, the wireless link measurement mode includes at least a normal measurement mode and a fast measurement mode. The normal measurement mode refers to setting the wireless link quality monitoring frequency of the terminal and the historical monitoring cycle duration corresponding to the link quality evaluation in accordance with the design method specified in the 3GPP (3rd Generation Partnership Project) standard protocol. Among them, the monitoring measurement to the data set size is fixed, and when the wireless link quality monitoring measurement frequency is increased, the historical monitoring cycle duration is shortened.
[0046] The monitoring measurement value refers to the measurement obtained by the terminal performing radio link monitoring (Radio Link Monitor, RLM) based on reference signals such as the Cell Reference Signal (CRS), the Synchronization Signal and PBCH Block (SSB), or the Channel State Information Reference Signal (CSI-RS). In some other embodiments of the present application, the monitoring measurement value is also referred to as the RLM measurement value.
[0047] The terminal can determine the quality evaluation value corresponding to the current evaluation time based on multiple monitoring measurement values within the previous historical monitoring cycle at the current evaluation time. In the implementation of this application, the wireless link quality evaluation value is referred to as the quality evaluation value.
[0048] In this embodiment, a data set Buffer is set to store monitoring measurement values, and the size of the Buffer can be determined according to the length of the historical monitoring cycle and the frequency of wireless link quality monitoring. The monitoring measurement values are written into the Buffer in a loop. For example, assuming that the size of the Buffer is N, the first monitoring measurement value is written into the first element of the Buffer; the second monitoring measurement value is written into the second element of the Buffer; ...; the Nth monitoring measurement value is written into the Nth element of the Buffer; the (N+1)th monitoring measurement value is written into the first element of the Buffer; the (N+2)th monitoring measurement value is written into the second element of the Buffer; the monitoring measurement values are stored in a regular loop in sequence; at the current evaluation moment, the quality evaluation value of the current evaluation moment is determined based on the data stored in the Buffer at the current evaluation moment. Exemplarily, the process of determining the quality evaluation value is shown in the following formula:
[0049] ;
[0050] in, is the quality assessment value, It is the nth monitored measurement value in the Buffer.
[0051] In a possible implementation, the terminal performs the first link quality assessment when the buffer is filled for the first time. After the terminal establishes the RRC connection for the first time, the initial state of the buffer is empty; after the terminal returns to the synchronization state from the pre-loss state, the buffer is cleared and the monitoring measurement value is recorded again. When the buffer is filled again, the first link quality assessment after returning to the synchronization state is performed.
[0052] In a possible implementation manner, the terminal performs the first link quality evaluation according to the evaluation period, and if the buffer is not full, calculates the quality evaluation value based on the monitoring measurement value currently stored in the buffer.
[0053] The terminal determines whether to maintain a synchronization state or enter a pre-out-of-step state based on the relationship between the quality evaluation value and the out-of-step threshold.
[0054] In the related art, during the wireless link quality monitoring process, the receiving end performs monitoring measurement according to a fixed wireless link measurement mode, that is, in the related art, the receiving end uses the same monitoring measurement frequency and the same historical monitoring cycle duration to obtain the monitoring measurement value and calculate the quality evaluation value in each evaluation period; and in this embodiment, at the current evaluation moment, the evaluation quality value corresponding to the current evaluation moment is determined based on the monitoring measurement value in the previous historical monitoring period, or the evaluation quality value corresponding to the current evaluation moment is determined based on all the monitoring measurement values in the Buffer corresponding to the current evaluation moment; and then the measurement mode corresponding to the next evaluation period is determined based on the monitoring measurement value in the previous historical monitoring period, or the measurement mode corresponding to the next evaluation period is determined based on all the monitoring measurement values in the Buffer. Among them, the evaluation period can also be called the link evaluation indication interval, that is, the interval at which the terminal performs link quality evaluation each time. In the continuous reception (non-Discontinuous Reception, referred to as non-DRX) mode, the link evaluation indication interval is 10ms or a multiple of 10ms; in the discontinuous reception (Discontinuous Reception, referred to as DRX) mode, the link evaluation indication interval is the DRX cycle or a multiple of the DRX cycle. In the embodiment of the present application, the link assessment indication interval can be designed according to the 3GPP standard protocol.
[0055] In this embodiment, the evaluation cycle durations corresponding to the normal measurement mode and the fast measurement mode are the same.
[0056] Step 204, when multiple monitoring measurement values meet the first preset condition, the monitoring measurement values are acquired in the fast measurement mode in the evaluation period after the current evaluation time until the terminal enters the pre-loss state or the terminal meets the second preset condition and the monitoring measurement values are acquired again in the normal measurement mode.
[0057] The measurement frequency corresponding to the fast measurement mode is greater than or equal to the measurement frequency corresponding to the normal measurement mode.
[0058] Please refer to Table 1, which is an example of parameter values corresponding to the normal measurement mode and the fast measurement mode in an implementation mode when the downlink receiving mode of the terminal is in the non-DRX mode. For ease of description, the normal measurement mode is referred to as the normal mode in each table of this embodiment, and the fast measurement mode is referred to as the fast mode.
[0059] Table 1
[0060]
[0061] Exemplarily, the evaluation period of the terminal is 20ms. Combined with Figure 1, in the normal measurement mode, the terminal performs a wireless link quality monitoring measurement every 10ms, performs a wireless link quality assessment every 20ms, and selects the 20 most recently acquired monitoring measurement values when evaluating the wireless link quality; if the recent multiple evaluation cycles all adopt the normal mode, it can be understood as selecting the monitoring measurement value within the last 200ms to calculate the quality assessment value. In the fast measurement mode, the terminal performs a wireless link quality monitoring measurement every 5ms, performs a wireless link quality assessment every 20ms, and selects the 20 most recently acquired monitoring measurement values when evaluating the wireless link quality; if the recent multiple evaluation cycles all adopt the fast measurement mode, it can be understood as selecting the monitoring measurement value within the last 100ms to calculate the quality assessment value.
[0062] Please refer to Table 2, which is an example of the numerical values of various parameters corresponding to the normal measurement mode and the fast measurement mode in an implementation mode, when the downlink receiving mode of the terminal is the DRX mode. In a possible implementation, when the receiving cycle duration corresponding to the DRX mode is less than the preset cycle duration, the normal measurement mode and the fast measurement mode are the same. In conjunction with Table 2, the preset cycle duration is 5ms, that is, when the DRX cycle duration is less than or equal to 5ms, the normal measurement mode and the fast measurement mode include the same measurement frequency, that is, 1 measurement per DRX cycle; in this way, this implementation method can not increase the measurement frequency of the fast measurement mode when the receiving cycle duration corresponding to the discontinuous reception mode is short, so as to avoid the measurement frequency being too high and occupying more computing resources. This implementation method can relatively reduce the occupation of computing resources on the basis of ensuring the measurement frequency. On the other hand, in this implementation, please refer to Table 2. When the receiving cycle duration corresponding to the DRX mode is less than the preset cycle duration, although the historical monitoring cycle duration corresponding to the normal measurement mode is greater than the historical monitoring cycle duration corresponding to the fast measurement mode, the Buffer size is the same, that is, when the DRX cycle is 2ms, only 50 monitoring measurement values close to the current evaluation time are selected in the normal measurement mode to determine the quality evaluation value and the measurement mode of the next evaluation cycle, thereby reducing data storage space and calculation amount while ensuring the measurement frequency and calculation accuracy.
[0063] Table 2
[0064]
[0065] The first preset condition includes that a proportion of the monitored measurement values that are smaller than the out-of-step threshold among the multiple monitored measurement values is greater than or equal to a first proportion.
[0066] If multiple monitoring measurement values meet the first preset condition, it is considered that the communication environment of the terminal at the current evaluation moment may be changing from good to bad. By increasing the measurement frequency to accelerate link quality monitoring, the wireless link quality evaluation can quickly track the link quality changes when the communication environment changes.
[0067] Exemplarily, the value range of the first ratio is 45% to 55%. Optionally, the first ratio is 50%, that is, the first preset condition includes: half or more of the link monitoring measurement values of the multiple monitoring measurement values are less than the out-of-step threshold.
[0068] Among them, in the 3GPP communication standard protocol, pre-out-of-sync refers to a temporary state before the terminal enters the out-of-sync state from the synchronization state. In this temporary state, if the terminal can meet the conditions for returning to the synchronization state within a preset time, the terminal returns to the synchronization state without triggering the RRC re-establishment process. Otherwise, the terminal enters the out-of-sync state and the RRC layer initiates the re-establishment process.
[0069] The terminal sets the out-of-step counter oos_counter to record the number of out-of-step times of the terminal. If the number of out-of-step times is greater than the pre-configured value, the terminal will enter the pre-out-of-step state. If the quality assessment value corresponding to the current assessment time is less than the out-of-step threshold, the out-of-step counter is incremented by 1. If the quality assessment value corresponding to the current assessment time is greater than the synchronization threshold, the out-of-step counter is cleared. If the quality assessment value corresponding to the current assessment time is less than or equal to the synchronization threshold and greater than or equal to the out-of-step threshold, the out-of-step counter is neither incremented nor cleared and remains unchanged.
[0070] In this embodiment, if multiple monitoring measurement values corresponding to the current evaluation time meet the first preset condition, it is considered that the current communication environment has deteriorated, and the terminal performs wireless link quality monitoring measurement in a fast measurement mode to quickly reflect changes in the wireless communication environment.
[0071] The second preset condition includes that a proportion of quality assessment values greater than the synchronization threshold among a plurality of consecutive quality assessment values after the current assessment moment is greater than or equal to a second proportion.
[0072] If during the continuous fast mode measurement, if the proportion of quality assessment values greater than the synchronization threshold in multiple consecutive quality assessment values is greater than or equal to the second proportion, it is considered that the communication environment of the terminal has recovered to a better state, and the monitoring measurement value can be obtained again according to the normal measurement mode.
[0073] Exemplarily, the value range of the second ratio is 70% to 80%. Optionally, the second ratio is 75%, that is, the second preset condition includes: in the process of the terminal monitoring the measurement value acquisition in the fast measurement mode, more than three quarters of the quality assessment values of multiple consecutive quality assessment values are greater than the synchronization threshold.
[0074] The wireless link quality monitoring method provided by the above embodiment includes: when the terminal is in a synchronous state and the current wireless link measurement mode of the terminal is a normal measurement mode, determining the measurement mode corresponding to the evaluation period after the current evaluation moment based on multiple monitoring measurement values corresponding to the current evaluation moment; when multiple monitoring measurement values meet a first preset condition, the monitoring measurement values are acquired in accordance with the fast measurement mode in the evaluation period after the current evaluation moment until the terminal enters a pre-out-of-step state or the terminal meets a second preset condition and acquires the monitoring measurement values in accordance with the normal measurement mode again, wherein the measurement frequency corresponding to the fast measurement mode is greater than or equal to the measurement frequency corresponding to the normal measurement mode, the first preset condition includes that the proportion of monitoring measurement values less than the out-of-step threshold in the multiple monitoring measurement values is greater than or equal to the first proportion, and the second preset condition includes that the proportion of quality evaluation values greater than the synchronization threshold in the multiple continuous quality evaluation values after the current evaluation moment is greater than or equal to the second proportion; in this way, when the terminal is in a synchronous state and the current wireless link measurement mode is the normal measurement mode, according to the current The relationship between the multiple monitoring measurement values corresponding to the pre-evaluation moment and the desynchronization threshold can identify the link quality deterioration at the first time, switch the wireless link measurement mode to the fast measurement mode, and speed up the link quality monitoring by increasing the number of terminal RLM measurements, so as to achieve the goal of quickly tracking the change of link quality, and continue to use the fast measurement mode until the communication environment continues to deteriorate so that the terminal enters the pre-desynchronization state or the communication environment improves and returns to the normal measurement mode; that is, in this embodiment, when the link quality is good, the terminal adopts the "long monitoring period + sparse RLM measurement opportunity" mode for monitoring, and when the link quality is poor, the terminal adopts the "short monitoring period + tight RLM measurement opportunity" mode for monitoring, avoiding the problem that the fixed monitoring period duration and measurement frequency used in the related technology lead to the link quality evaluation value being unable to quickly reflect the change of the wireless link quality, resulting in a large lag in the terminal's judgment on the current communication quality. The wireless link quality monitoring method provided by this embodiment can reduce the delay in the terminal's judgment on the current communication quality and improve the real-time judgment on the current communication quality.
[0075] In an exemplary embodiment, based on Figure 2In the illustrated embodiment, the wireless link quality monitoring method provided also includes: when multiple monitoring measurement values do not meet the first preset condition, acquiring monitoring measurement values according to the normal measurement mode in the next evaluation period corresponding to the current evaluation time.
[0076] If the plurality of monitoring measurement values do not satisfy the first preset condition, it is considered that the current communication environment of the terminal is good, and the monitoring measurement values are acquired in the next evaluation period in the normal measurement mode.
[0077] In an exemplary embodiment, based on Figure 2 In the illustrated embodiment, the provided wireless link quality monitoring method also includes: when multiple monitoring measurement values do not meet the first preset condition, if the multiple monitoring measurement values meet the third preset condition, then in the next evaluation period corresponding to the current evaluation moment, the monitoring measurement values are acquired according to the normal measurement mode; if the multiple monitoring measurement values do not meet the third preset condition, then in the next evaluation period corresponding to the current evaluation moment, the monitoring measurement values can be acquired according to the normal measurement mode or the fast measurement mode. The specific selection of which measurement mode is related to the hardware setting of the terminal, that is, the measurement mode corresponding to the next evaluation period when multiple monitoring measurement values do not meet the first preset condition or the third preset condition is set in advance according to the hardware situation of the terminal.
[0078] The third preset condition includes that the multiple monitored measurement values are all greater than the out-of-step threshold and the proportion of the monitored measurement values greater than or equal to the synchronization threshold among the multiple monitored measurement values is greater than or equal to the first proportion.
[0079] Exemplarily, if multiple monitoring measurement values do not meet the third preset condition, the terminal obtains the monitoring measurement values in the next evaluation period of the current evaluation moment according to the fast measurement mode, then the next evaluation moment of the current evaluation moment continues to select the measurement mode of the next evaluation period according to whether the multiple monitoring measurement values meet the first preset condition, which is different from the loop branch in which multiple evaluation periods are entered according to the fast measurement mode after the multiple monitoring measurement values meet the first preset condition.
[0080] In an exemplary embodiment, based on Figure 2 For the examples shown, please refer to Figure 3 This embodiment involves a process in which the monitoring measurement value is acquired in accordance with the fast measurement mode in the evaluation period after the current evaluation moment until the terminal enters the pre-loss state or the terminal meets the second preset condition and then acquires the monitoring measurement value in accordance with the normal measurement mode again. Figure 3 As shown, the process includes steps 302 to 306, wherein:
[0081] Step 302: Obtain monitoring measurement values in a fast measurement mode in a first number of evaluation periods after the current evaluation time.
[0082] The first number is a threshold value of the number of cumulative out-of-step times corresponding to the terminal entering the pre-out-of-step state. For the convenience of description, the first number is recorded as M.
[0083] Exemplarily, the cumulative out-of-sync threshold configured by the terminal is 6, that is, when switching from the normal measurement mode to the fast measurement mode, the fast measurement mode is used for monitoring measurement value acquisition for 6 consecutive evaluation cycles.
[0084] Step 304: If the terminal does not enter the pre-loss state and the proportion of quality evaluation values greater than the synchronization threshold in the first number of quality evaluation values is greater than or equal to a second proportion, acquire monitoring measurement values in the next evaluation period according to the normal measurement mode.
[0085] Wherein, no matter whether the normal measurement mode or the fast measurement mode is adopted to perform the wireless link quality monitoring measurement, if the cumulative number of out-of-sync times counted by the terminal reaches a pre-configured threshold, the terminal enters a pre-out-of-sync state.
[0086] When the terminal does not enter the pre-loss state, the terminal completes M consecutive quality assessments in the fast measurement mode, and counts the relationship between the M quality assessment values and the synchronization threshold. If the quality assessment value greater than the synchronization threshold among the M quality assessment values is greater than or equal to the second ratio, it is considered that the communication environment of the terminal has recovered to a better state, and the monitoring measurement value is obtained in the next evaluation period according to the normal measurement mode.
[0087] Step 306: When the terminal does not enter the pre-loss state and the proportion of quality evaluation values greater than the synchronization threshold in the first number of quality evaluation values is less than a second proportion, monitoring measurement values are continuously acquired in the fast measurement mode in the next first number of evaluation periods.
[0088] If the proportion of the quality evaluation values greater than the synchronization threshold in the M quality evaluation values is less than the second proportion, it is considered that the communication environment of the terminal has not been restored, and the fast measurement mode of M evaluation cycles is maintained.
[0089] In this embodiment, after the terminal adopts the fast measurement mode, a fast measurement time period is determined based on the cumulative desynchronization threshold of the terminal entering the pre-desynchronization state, and the fast measurement mode is used in the fast measurement time period to quickly track changes in the current communication environment.
[0090] In an exemplary embodiment, based on Figure 2In the illustrated embodiment, the wireless link quality monitoring method provided also includes: when the terminal is in a pre-out-of-step state, monitoring measurement values are acquired in a fast measurement mode until the terminal is in a synchronization state or an out-of-step state.
[0091] Among them, when the terminal enters the pre-desynchronization state, it can be considered that the quality of the wireless link has been preliminarily judged to be poor and has reached the edge of desynchronization. At this time, the wireless link measurement mode only uses the fast measurement mode to quickly and closely track the changes in link quality.
[0092] Exemplarily, after entering the pre-loss state, the terminal uses the configured T310 timer and N311 counter, wherein the T310 timer is used to limit the preset duration of the terminal in the pre-loss state, and the N311 counter is used to record the number of times that the current link quality value of the terminal in the pre-loss state is continuously greater than the synchronization threshold; wherein, in the pre-loss state, the terminal always uses the fast mode to monitor the wireless link quality, and before the T310 timer times out, records the quality assessment value corresponding to each assessment moment, and as long as there is one time when the quality assessment value corresponding to a certain assessment moment is less than the desynchronization threshold, the N311 counter is cleared; when the T310 timer times out, the N311 counter has not reached the configured preset number of synchronizations, at which time the terminal will enter the desynchronization state, and the terminal needs to execute the RRC re-establishment process; before the T310 timer times out, the N311 counter reaches the configured preset number of synchronizations, at which time the terminal returns to the synchronization state.
[0093] In a possible implementation of this embodiment, when the downlink receiving mode of the terminal is a continuous receiving mode, the fast measurement mode includes a first fast measurement mode and a second fast measurement mode, wherein the historical monitoring cycle duration of the second fast measurement mode is less than the historical monitoring cycle duration of the first fast measurement mode. Exemplarily, the fast measurement mode in Table 1 is the first fast measurement mode, and correspondingly, the second fast measurement mode includes a historical monitoring cycle duration of 50ms, a measurement frequency of once every 5ms, and a corresponding Buffer size of 10 monitoring measurement values. In this example, when the terminal is in a synchronous state, the fast measurement mode is the first fast measurement mode, and when the terminal is in a pre-loss state, the fast measurement mode is the second fast measurement mode, that is, the historical monitoring cycle duration is shortened, and the 10 monitoring measurement values closest to the current evaluation time are used to determine the quality evaluation value, and the link quality changes are tracked more closely.
[0094] In a possible implementation manner of this embodiment, when the terminal is in the pre-loss state, the terminal obtains the monitoring measurement value according to the same fast measurement mode as that in the synchronization state.
[0095] In an exemplary embodiment, Figure 4As shown, a wireless line quality monitoring method is provided, which is described by taking the method applied to the terminal 102 in FIG. 1 as an example, and includes the following steps 402 to 404. Among them:
[0096] Step S402: When the terminal is in a synchronous state and the current radio link measurement mode of the terminal is a normal measurement mode, it is determined whether multiple monitoring measurement values corresponding to the current evaluation time meet a first preset condition. The first preset condition includes that the proportion of the monitoring measurement values less than the desynchronization threshold in the multiple monitoring measurement values is greater than or equal to a first proportion.
[0097] Step S404: If multiple monitoring measurement values meet the first preset condition, monitoring measurement values are acquired in a first number of evaluation periods after the current evaluation time according to the fast measurement mode, wherein the first number is the cumulative out-of-step count threshold corresponding to the terminal entering the pre-out-of-step gait.
[0098] Among them, the measurement frequency corresponding to the fast measurement mode is greater than or equal to the measurement frequency corresponding to the normal measurement mode. Optionally, when the downlink reception mode of the terminal is a discontinuous reception mode and the reception cycle duration corresponding to the discontinuous reception mode is less than the preset cycle duration, the measurement frequency of the normal measurement mode is the same as the measurement frequency of the fast measurement mode.
[0099] Step S406: If the terminal does not enter the pre-loss state, determine whether the terminal meets a second preset condition, wherein the second preset condition includes that the proportion of quality evaluation values greater than the synchronization threshold in the first number of quality evaluation values is greater than or equal to a second proportion.
[0100] Step S408: If the terminal meets the second preset condition when the terminal does not enter the pre-loss gait, the monitoring measurement value is acquired according to the normal measurement mode in the next evaluation cycle, and the process returns to step 402 to continue execution.
[0101] If the terminal does not meet the second preset condition when the terminal does not enter the pre-loss gait, the process jumps back to step 404 to continue to acquire monitoring measurement values in the fast measurement mode in the next first number of evaluation cycles.
[0102] Step S410: When the terminal is in a pre-gait loss state, monitoring measurement values are acquired in a fast measurement mode until the terminal is in a synchronization state or a gait loss state.
[0103] Optionally, when the downlink receiving mode of the terminal is a continuous receiving mode, the fast measurement mode includes a first fast measurement mode and a second fast measurement mode, and the historical monitoring cycle length of the second fast measurement mode is shorter than the historical monitoring cycle length of the first fast measurement mode; wherein, when the terminal is in a synchronous state, the fast measurement mode is the first fast measurement mode; when the terminal is in a pre-loss state, the fast measurement mode is the second fast measurement mode.
[0104] Step 412: When the plurality of monitored measurement values do not satisfy the first preset condition, the monitored measurement values are acquired in a normal measurement mode in a next evaluation period corresponding to the current evaluation time.
[0105] Exemplarily, for an LTE wireless communication system, a cell reference signal (CRS) is used for downlink radio link monitoring (RLM). In the case of continuous reception mode, it is assumed that the terminal physical layer RLM measurement frequency in normal measurement mode is 1 RLM measurement every 10 ms, the historical monitoring cycle duration is 200 ms, and the size of the corresponding monitoring measurement value data set Buffer is N=20; wherein,
[0106] Step A1, when the terminal is just in synchronization, the buffer is empty. When the buffer is filled with 20 monitoring measurement values for the first time, the first link quality assessment is performed: the quality assessment value Qc corresponding to the current assessment time is calculated first, and then Qc is compared with the synchronization and desynchronization threshold.
[0107] If Qc is less than the out-of-step threshold, the out-of-step counter oos_counter is incremented by 1; if Qc is greater than the synchronization threshold, the out-of-step counter oos_counter is cleared to 0; if Qc is between the out-of-step threshold and the synchronization threshold, the out-of-step counter oos_counter is neither incremented nor cleared to 0 and remains unchanged. When the out-of-step counter oos_counter reaches the pre-configured threshold (M=6 in this example), the terminal enters the pre-out-of-step state.
[0108] After the terminal completes the first link quality assessment, it then performs periodic link quality assessments according to the link assessment indication interval P as a step size. In this example, P=20ms is used as an example to illustrate the implementation process of this example. Each subsequent link quality assessment requires a measurement mode switching judgment before performing link quality assessment.
[0109] Step A2, taking the first ratio of 50% as an example, when more than half of all the monitored measurement values in the buffer are less than the desynchronization threshold, switch to the fast measurement mode; wherein the RLM measurement frequency corresponding to the fast measurement mode is to perform an RLM measurement every 5ms, and write the RLM measurement value of each RLM measurement opportunity into the buffer. When the link evaluation indication interval reaches 20ms, a link quality evaluation is performed, and the link quality evaluation process is the same as the first link quality evaluation process in step 1.
[0110] Among them, for the normal measurement mode and the fast measurement mode, the monitoring measurement values obtained at each RLM measurement time are written into the buffer in a loop. If the buffer size is 20, then the first monitoring measurement value is written into the first element of the buffer; the second monitoring measurement value is written into the second element of the buffer; ...; the 20th monitoring measurement value is written into the 20th element of the buffer; the 21st monitoring measurement value is written into the first element of the buffer; the 22nd monitoring measurement value is written into the second element of the buffer; and so on and so forth.
[0111] Step A3, when just switching to fast measurement mode, the terminal will remain in fast measurement mode for a period of time, that is, keep using fast measurement mode for measurement (M*link assessment indication interval P) ms = 6*20ms=120ms. Within 120ms, the terminal will perform a maximum of 6 link quality assessments, that is, compare with the synchronization loss threshold at most 6 times. If the out-of-step counter oos_counter has reached 6 times during the execution of 6 link quality assessments, the terminal will directly enter the pre-out-of-step state; otherwise, 6 comparisons will be completed, and then the measurement mode needs to be switched based on the results of these 6 comparisons. At this time, the measurement mode switching criteria are: if the number of comparison results greater than the synchronization threshold accounts for 3 / 4 or more of the 6 times, then switch to normal measurement mode; otherwise, continue to maintain fast measurement mode.
[0112] If the fast measurement mode is maintained, the link quality assessment will continue for the next 120ms. That is, in the next 120ms, the fast measurement mode will be used for measurement. During this 120ms period, the terminal will perform a maximum of 6 link quality assessments. If the out-of-step counter oos_counter has reached 6 times during the 6 assessments, the terminal will directly enter the pre-out-of-step state; otherwise, 6 comparisons will be completed, and then the need to switch the measurement mode will be determined based on the results of the 6 comparisons. If the fast measurement mode is selected again at this time, the above process will be repeated, that is, the fast measurement mode will be used for link quality assessment in the next 120ms; if the normal measurement mode is selected at this time, the link measurement will be performed in the normal measurement mode. After completing one link quality assessment, the need to switch the measurement mode will be determined according to the first preset condition.
