Using the above wireless link quality monitoring method can reduce the delay of the terminal's judgment of the current communication quality and improve the real-time performance of the terminal's judgment of the current communication quality.

[0039] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to 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 by the embodiments of the present application can be applied to an application environment as Figure 1 shown. Among them, the terminal 102 communicates with the network device 104 through a network. Among them, the terminal (Terminal Equipment, TE) 102 can also be called a user equipment (User Equipment, UE). The terminal 102 can be various mobile devices. For example, it can be a mobile phone (or a "cellular" phone), a computer with a mobile terminal, etc., and can also be a portable, pocket-sized, handheld, computer-integrated or vehicle-mounted mobile device. The network device 104 can be a device for communicating with the terminal 102. For example, it can be a base transceiver station (abbreviated as "BTS") in a GSM (Global System for Mobile Communications) system or a CDMA (Code Division Multiple Access) system, or a base station (NodeB, abbreviated as "NB") in a WCDMA (Wideband Code Division Multiple Access) system, or an evolved base station (Evolutional Node B, abbreviated 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, as Figure 2 shown, a method for monitoring wireless line quality is provided. Taking the terminal 102 in Figure 1 as an example, the method includes the following steps 202 to 204. Among them:

[0042] Step 202: When the terminal is in the synchronized state and the current wireless link measurement mode of the terminal is the normal measurement mode, determine the measurement mode corresponding to the evaluation period after the current evaluation moment based on multiple listening measurement values corresponding to the current evaluation moment.

[0043] Among them, the synchronized state means that the block error rate of the receiving end demodulating the received signal is lower than a certain block error rate threshold, which can ensure that the terminal can receive the data sent by the sending end more reliably. The out-of-synchronized state means that the block error rate of the receiving end demodulating the received signal is higher than a certain block error rate threshold, and it can no longer ensure that the terminal can receive the data sent by the sending end more reliably. The out-of-synchronized state may be caused by signal attenuation, time delay change, frequency offset, phase distortion, etc. in signal transmission, resulting in a weak signal strength at the receiving end or the signal being interfered by noise, etc., thus 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 synchronized state, so as to ensure the reliable transmission of data. When the receiving end is in the out-of-synchronized 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 listening measurement frequency of wireless link quality, the duration of the historical monitoring period corresponding to link quality evaluation, and the size of the listening measurement value data set; among them, exemplarily, the listening measurement value data set is implemented using a data buffer area.

[0045] In this embodiment, the wireless link measurement mode includes at least two types: the normal measurement mode and the fast measurement mode. The normal measurement mode means setting the wireless link quality monitoring frequency and the duration of the historical monitoring period corresponding to link quality evaluation of the terminal in accordance with the design method specified in the 3GPP (3rd Generation Partnership Project) standard protocol. Among them, the size of the listening measurement to data set is fixed. When increasing the listening measurement frequency of wireless link quality, the duration of the historical monitoring period is shortened.

[0046] Among them, the listening measurement value refers to the value obtained by the terminal through radio link monitoring (RLM) measurement based on reference signals such as cell reference signal (CRS for short), synchronization signal block (SSB for short), or channel state information reference signal (CSI-RS for short). In some other embodiments of this application, the listening measurement value is also referred to as the RLM measurement value.

[0047] Among them, the terminal can determine the quality evaluation value corresponding to the current evaluation moment based on multiple listening measurement values within the duration of the previous historical monitoring period at the current evaluation moment. In this application, the wireless link quality evaluation value is simply referred to as the quality evaluation value.

[0048] In this embodiment, a data set Buffer is set up to store the listening measurement values. The size of this Buffer can be determined according to the duration of the historical monitoring period and the wireless link quality monitoring frequency. The listening measurement values are cyclically written into the Buffer. For example, assuming the size of the Buffer is N, then the first listening measurement value is written into the first element of the Buffer; the second listening measurement value is written into the second element of the Buffer;...; the Nth listening measurement value is written into the Nth element of the Buffer; the (N + 1)th listening measurement value is written into the first element of the Buffer; the (N + 2)th listening measurement value is written into the second element of the Buffer; and so on, storing the listening measurement values in a cyclic pattern according to this rule. At the current evaluation moment, the quality evaluation value at 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] Among them, is the quality evaluation value, is the nth listening measurement value in the Buffer.

[0051] In a possible implementation manner, the terminal performs the first link quality evaluation when the Buffer is full 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 synchronized state from the pre-out-of-step situation, the Buffer is cleared and starts recording the listening measurement values again. When the Buffer is full again, the first link quality evaluation after returning to the synchronized state is performed.

[0052] In a possible implementation, the terminal performs the first link quality assessment according to the evaluation period. If the Buffer is not full, the quality assessment value is calculated based on the listening measurement values stored in the current Buffer.

[0053] Based on the relationship between the quality assessment value and the out-of-sync threshold, the terminal determines whether to maintain the synchronous state or enter the pre-out-of-sync state.

[0054] In the related art, during the wireless link quality monitoring process, the receiving end performs listening measurements according to a fixed wireless link measurement mode, that is, in the related art, the receiving end uses the same listening measurement frequency and the same historical monitoring period duration in each evaluation period to obtain the listening measurement values and calculate the quality assessment value; while in this embodiment, at the current evaluation moment, the evaluation quality value corresponding to the current evaluation moment is determined based on the listening measurement values in the previous historical monitoring period or the evaluation quality value corresponding to the current evaluation moment is determined based on all the listening measurement values in the Buffer corresponding to the current evaluation moment; then the measurement mode corresponding to the next evaluation period is determined based on the listening measurement values in the previous historical monitoring period or the measurement mode corresponding to the next evaluation period is determined based on all the listening measurement values in the Buffer. Among them, the evaluation period can also be referred to as the link evaluation indication interval, that is, the interval between each link quality assessment of the terminal. In the continuous reception (non-Discontinuous Reception, abbreviated as non-DRX) mode, the link evaluation indication interval is 10 ms or a multiple of 10 ms; in the discontinuous reception (Discontinuous Reception, abbreviated as DRX) mode, the link evaluation indication interval is the DRX period or a multiple of the DRX period. In the embodiments of the present application, the link evaluation indication interval can be designed according to the 3GPP standard protocol.

[0055] Among them, in this embodiment, the evaluation period durations corresponding to the normal measurement mode and the fast measurement mode are the same.

[0056] Step 204, when multiple listening measurement values meet the first preset condition, listening measurement values are obtained according to the fast measurement mode in the evaluation periods after the current evaluation moment until the terminal enters the pre-out-of-sync state or the terminal meets the second preset condition and resumes obtaining listening measurement values according to the normal measurement mode.

[0057] 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.

[0058] Please refer to Table 1. For an implementation manner, when the downlink receiving mode of the terminal is in the non-DRX mode, the following are numerical examples of the parameters corresponding to the normal measurement mode and the fast measurement mode. For ease of description, in the tables of this embodiment, the normal measurement mode is abbreviated as the normal mode, and the fast measurement mode is abbreviated as the fast mode.

[0059] Table 1

[0060]

[0061] Exemplarily, the evaluation period of the terminal is 20 ms. Combining Figure 1 , where, in the normal measurement mode, the terminal performs wireless link quality listening measurements every 10 ms and wireless link quality evaluations every 20 ms. When performing the wireless link quality evaluation, the 20 most recently obtained listening measurement values are selected; if the normal mode has been used in multiple recent evaluation periods, it can be understood that the listening measurement values within the most recent 200 ms are selected to calculate the quality evaluation value. In the fast measurement mode, the terminal performs wireless link quality listening measurements every 5 ms and wireless link quality evaluations every 20 ms. When performing the wireless link quality evaluation, the 20 most recently obtained listening measurement values are selected; if the fast measurement mode has been used in multiple recent evaluation periods, it can be understood that the listening measurement values within the most recent 100 ms are selected to calculate the quality evaluation value.

[0062] Please refer to Table 2. For an implementation manner, when the downlink receiving mode of the terminal is in the DRX mode, the following are numerical examples of the parameters corresponding to the normal measurement mode and the fast measurement mode. In a possible implementation manner, 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. Combining Table 2, the preset cycle duration is 5 ms, that is, when the DRX cycle duration is less than or equal to 5 ms, the measurement frequencies included in the normal measurement mode and the fast measurement mode are the same, that is, 1 measurement per DRX cycle; thus, this implementation manner can, when the receiving cycle duration corresponding to the discontinuous reception mode is relatively small, not increase the measurement frequency of the fast measurement mode, avoiding too high a measurement frequency occupying more computing resources. This implementation manner can relatively reduce the occupation of computing resources while ensuring the measurement frequency. On the other hand, in this implementation manner, 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 sizes are the same. That is, when the DRX cycle is 2 ms, in the normal measurement mode, only 50 listening measurement values close to the current evaluation moment are selected to determine the quality evaluation value and the measurement mode for the next evaluation cycle, reducing the data storage space and the amount of calculation while ensuring the measurement frequency and calculation accuracy.

[0063] Table 2

[0064]

[0065] Among them, the first preset condition includes that the proportion of the listening measurement values less than the out-of-step threshold among multiple listening measurement values is greater than or equal to the first proportion.

[0066] If multiple listening measurement values meet the first preset condition, it is considered that the communication environment where the terminal is located at the current evaluation moment may be deteriorating from good to bad, and the measurement frequency is increased to accelerate the link quality monitoring, so that the wireless link quality assessment can quickly track the link quality change when the communication environment changes.

[0067] Exemplarily, the value range of the first proportion is 45% to 55%. Optionally, the first proportion is 50%, that is, the first preset condition includes: half or more of the link listening measurement values among multiple listening measurement values are less than the out-of-step threshold.

[0068] Among them, in the 3GPP communication standard protocol, the pre-out-of-step state refers to a temporary state before the terminal enters the out-of-step state from the synchronized state. In this temporary state, if the terminal can meet the condition of returning to the synchronized state within the preset time, the terminal returns to the synchronized state and does not need to trigger the RRC re-establishment process. Otherwise, the terminal enters the out-of-step state and the RRC layer initiates the re-establishment process.

[0069] Among them, the terminal sets an out-of-step counter oos_counter to record the number of times the terminal is out of step. 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. Among them, if the quality assessment value corresponding to the current evaluation moment 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 evaluation moment is greater than the synchronization threshold, the out-of-step counter is cleared. If the quality assessment value corresponding to the current evaluation moment 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 listening measurement values corresponding to the current evaluation moment meet the first preset condition, it is considered that the current communication environment has deteriorated, and the terminal performs wireless link quality listening measurement according to the fast measurement mode to quickly reflect the change of the wireless communication environment.

[0071] Among them, the second preset condition includes that the proportion of the quality assessment values greater than the synchronization threshold among multiple consecutive quality assessment values after the current evaluation moment is greater than or equal to the second proportion.

[0072] If, during the continuous fast mode measurement, the proportion of quality evaluation values greater than the synchronization threshold among multiple consecutive quality evaluation values is greater than or equal to the second proportion, it is considered that the communication environment of the terminal has returned to a better state, and the terminal can resume listening for measurement values according to the normal measurement mode.

[0073] Exemplarily, the value range of the second proportion is from 70% to 80%. Optionally, the second proportion is 75%, that is, the second preset condition includes: during the process of the terminal listening for measurement values according to the fast measurement mode, more than three-quarters of the multiple consecutive quality evaluation 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 the synchronized state and the current wireless link measurement mode of the terminal is the normal measurement mode, determining the measurement mode corresponding to the evaluation period after the current evaluation moment based on multiple listening measurement values corresponding to the current evaluation moment; when the multiple listening measurement values meet the first preset condition, listening for measurement values according to the fast measurement mode in the evaluation period after the current evaluation moment until the terminal enters the pre-out-of-step state or the terminal meets the second preset condition and resumes listening for measurement values according to the normal measurement mode, where 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 listening measurement values less than the out-of-step threshold among the multiple listening 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 among multiple consecutive 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 the synchronized state and the current wireless link measurement mode is the normal measurement mode, according to the relationship between the multiple listening measurement values corresponding to the current evaluation moment and the out-of-step threshold, the terminal can identify that the link quality has deteriorated in a timely manner, 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 the link quality, and always adopt the fast measurement mode until the communication environment continues to deteriorate and the terminal enters the pre-out-of-step 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 uses the "long monitoring period + sparse RLM measurement opportunity" mode for monitoring, and when the link quality is poor, the terminal uses the "short monitoring period + dense RLM measurement opportunity" mode for monitoring, avoiding the problem in the related art that the fixed monitoring period duration and measurement frequency result in the link quality evaluation value being unable to quickly reflect the change of the wireless link quality, leading to a large lag in the terminal's judgment of the current communication quality. Using the wireless link quality monitoring method provided by this embodiment can reduce the delay of the terminal's judgment of the current communication quality and improve the real-time performance of the terminal's judgment of the current communication quality.

[0075] In an exemplary embodiment, based on Figure 2 the embodiment shown, the provided wireless link quality monitoring method further includes: when multiple listening measurement values do not meet the first preset condition, obtaining listening measurement values according to the normal measurement mode in the next evaluation period corresponding to the current evaluation moment.

[0076] Wherein, if multiple listening measurement values do not meet the first preset condition, it is considered that the current communication environment of the terminal is good, and the listening measurement values will continue to be obtained according to the normal measurement mode in the next evaluation period.

[0077] In an exemplary embodiment, based on Figure 2 the embodiment shown, the provided wireless link quality monitoring method further includes: when multiple listening measurement values do not meet the first preset condition, if multiple listening measurement values meet the third preset condition, obtaining listening measurement values according to the normal measurement mode in the next evaluation period corresponding to the current evaluation moment; if multiple listening measurement values do not meet the third preset condition, the listening measurement values can be obtained according to the normal measurement mode or the fast measurement mode in the next evaluation period corresponding to the current evaluation moment. Which measurement mode to specifically select is related to the hardware settings of the terminal, that is, the measurement mode corresponding to the next evaluation period is set in advance according to the hardware situation of the terminal when multiple listening measurement values do not meet the first preset condition and do not meet the third preset condition.

[0078] Wherein, the third preset condition includes that multiple listening measurement values are all greater than the out-of-step threshold and the proportion of listening measurement values greater than or equal to the synchronization threshold among multiple listening measurement values is greater than or equal to the first proportion.

[0079] Exemplarily, if in the case that multiple listening measurement values do not meet the third preset condition, the next evaluation period of the current evaluation moment obtains listening measurement values according to the fast measurement mode on the terminal, then the next evaluation moment of the current evaluation moment continues to select the measurement mode of the next next evaluation period according to whether multiple listening measurement values meet the first preset condition, which is different from the loop branch that enters the fast measurement mode in multiple evaluation periods after multiple listening measurement values meet the first preset condition.

[0080] In an exemplary embodiment, based on Figure 2 the embodiment shown, please refer to Figure 3 , this embodiment relates to the process of obtaining listening measurement values according to the fast measurement mode in the evaluation periods after the current evaluation moment until the terminal enters the pre-out-of-step state or the terminal meets the second preset condition and resumes obtaining listening measurement values according to the normal measurement mode. As Figure 3 shown, this process includes steps 302 to 306, wherein:

[0081] Step 302: Obtain the monitored measurement values according to the fast measurement mode in the first number of evaluation periods after the current evaluation moment.

[0082] Wherein, the first number is the cumulative number of out-of-step times threshold corresponding to the terminal entering the pre-out-of-step gait. For the sake of convenience of description, the first number is denoted as M.

[0083] Exemplarily, the cumulative number of out-of-step times 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 to obtain the monitored measurement values in 6 consecutive evaluation periods.

[0084] Step 304: When the terminal does not enter the pre-out-of-step gait and the proportion of the quality evaluation values greater than the synchronization threshold among the first number of quality evaluation values is greater than or equal to the second proportion, obtain the monitored measurement values according to the normal measurement mode in the next evaluation period.

[0085] Wherein, whether the wireless link quality is monitored and measured according to the normal measurement mode or the fast measurement mode, if the cumulative number of out-of-step times counted by the terminal reaches the pre-configured threshold, the terminal enters the pre-out-of-step gait.

[0086] When the terminal does not enter the pre-out-of-step gait, the terminal completes the quality evaluation according to the fast measurement mode for M consecutive times and counts the relationship between these M quality evaluation values and the synchronization threshold. If the number of quality evaluation values greater than the synchronization threshold among these M quality evaluation 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 monitored measurement values are obtained according to the normal measurement mode in the next evaluation period.

[0087] Step 306: When the terminal does not enter the pre-out-of-step gait and the proportion of the quality evaluation values greater than the synchronization threshold among the first number of quality evaluation values is less than the second proportion, continue to obtain the monitored measurement values according to the fast measurement mode in the subsequent first number of evaluation periods.

[0088] Wherein, if the proportion of the quality evaluation values greater than the synchronization threshold among these M quality evaluation values is less than the second proportion, it is considered that the communication environment of the terminal has not recovered, and the fast measurement mode for M evaluation periods is continued.

[0089] In this embodiment, after the terminal adopts the fast measurement mode, a fast measurement time period will be determined based on the cumulative number of out-of-step times threshold for the terminal to enter the pre-out-of-step gait, and the fast measurement mode is used to quickly track the change of the current communication environment in this fast measurement time period.

[0090] In an exemplary embodiment, based on Figure 2In the embodiment shown, the provided method for monitoring wireless link quality further includes: when the terminal is in a pre-out-of-step state, obtaining listening measurement values according to a fast measurement mode until the terminal is in a synchronized state or an out-of-step state.

[0091] Among them, when the terminal enters the pre-out-of-step state, it can be considered that the wireless link quality has been initially judged to be poor, reaching the edge of out-of-step. At this time, only the fast measurement mode is used for the wireless link measurement mode to quickly and closely track the change of link quality.

[0092] Exemplarily, after the terminal enters the pre-out-of-step state, the terminal uses the configured T310 timer and N311 counter. Among them, the T310 timer is used to define the preset duration for the terminal to be in the pre-out-of-step state, and the N311 counter is used to record the number of times the current link quality value of the terminal in the pre-out-of-step state is continuously greater than the synchronization threshold; among them, in the pre-out-of-step state, the terminal always uses the fast mode to monitor the wireless link quality. Before the T310 timer times out, record the quality evaluation values corresponding to each evaluation moment. As long as there is once that the quality evaluation value corresponding to a certain evaluation moment is less than the out-of-step threshold, the N311 counter is cleared; when the T310 timer times out and the N311 counter has not reached the configured preset synchronization times, at this time the terminal will enter the out-of-step 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 synchronization times, and at this time the terminal returns to the synchronized state.

[0093] In a possible implementation manner of this embodiment, when the downlink reception mode of the terminal is the continuous reception mode, the fast measurement mode includes a first fast measurement mode and a second fast measurement mode, where the historical monitoring period duration of the second fast measurement mode is less than the historical monitoring period duration of the first fast measurement mode. Exemplarily, in Table 1, the fast measurement mode is the first fast measurement mode. Correspondingly, the historical monitoring period duration included in the second fast measurement mode is 50 ms, the measurement frequency is 1 time per 5 ms, and the corresponding Buffer size is 10 listening measurement values. In this example, when the terminal is in the synchronized state, the fast measurement mode is the first fast measurement mode, and when the terminal is in the pre-out-of-step state, the fast measurement mode is the second fast measurement mode, that is, shortening the historical monitoring period duration and using the 10 listening measurement values closest to the current evaluation moment to determine the quality evaluation value to more closely track the change of link quality.

[0094] In a possible implementation manner of this embodiment, when the terminal is in the pre-out-of-step state, it obtains listening measurement values according to the same fast measurement mode as in the synchronized state.

[0095] In an exemplary embodiment, such as Figure 4As shown, a method for monitoring the quality of a wireless line is provided. Taking the terminal 102 in Figure 1 as an example for illustration, it includes the following steps 402 to step 404. Among them:

[0096] Step S402, when the terminal is in the synchronized state and the current wireless link measurement mode of the terminal is the normal measurement mode, determine whether multiple listening measurement values corresponding to the current evaluation moment meet the first preset condition. Among them, the first preset condition includes that the proportion of the listening measurement values less than the out-of-step threshold among the multiple listening measurement values is greater than or equal to the first proportion.

[0097] Step S404, if the multiple listening measurement values meet the first preset condition, then obtain the listening measurement values according to the fast measurement mode in the first number of evaluation cycles after the current evaluation moment, where the first number is the cumulative out-of-step count threshold corresponding to the terminal entering the pre-out-of-step state.

[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 the discontinuous reception mode and the duration of the reception cycle 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, when the terminal has not entered the pre-out-of-step state, determine whether the terminal meets the second preset condition. Among them, the second preset condition includes that the proportion of the quality evaluation values greater than the synchronization threshold among the first number of quality evaluation values is greater than or equal to the second proportion.

[0100] Step S408, if the terminal meets the second preset condition when the terminal has not entered the pre-out-of-step state, obtain the listening measurement values according to the normal measurement mode in the next evaluation cycle, and jump back to step 402 to continue execution.

[0101] Among them, if the terminal does not meet the second preset condition when the terminal has not entered the pre-out-of-step state, jump back to step 404 to continue execution and continue to obtain the listening measurement values according to the fast measurement mode in the subsequent first number of evaluation cycles.

[0102] Step S410, when the terminal is in the pre-out-of-step state, obtain the listening measurement values according to the fast measurement mode until the terminal is in the synchronized state or the out-of-step state.

[0103] Optionally, when the downlink receiving mode of the terminal is the continuous receiving mode, the fast measurement mode includes a first fast measurement mode and a second fast measurement mode, and the historical monitoring period duration of the second fast measurement mode is less than that of the first fast measurement mode; wherein, when the terminal is in the synchronized state, the fast measurement mode is the first fast measurement mode; when the terminal is in the pre-out-of-step state, the fast measurement mode is the second fast measurement mode.

[0104] Step 412, when the multiple listening measurement values do not meet the first preset condition, obtain the listening measurement values according to the normal measurement mode in the next evaluation period corresponding to the current evaluation moment.

[0105] Exemplarily, for an LTE wireless communication system, the cell reference signal (CRS) is used for downlink radio link monitoring (RLM). In the case of the continuous receiving mode, assuming that the RLM measurement frequency of the terminal physical layer in the normal measurement mode is 1 RLM measurement every 10 ms, and the historical monitoring period duration is 200 ms, the size N of the corresponding listening measurement value data set Buffer is 20; wherein,

[0106] Step A1, when the terminal just enters the synchronized state, Buffer is empty. When Buffer is first filled with 20 listening measurement values, the first link quality evaluation is performed: first calculate the quality evaluation value Qc corresponding to the current evaluation moment, and then compare Qc with the out-of-sync threshold.

[0107] Wherein, if Qc is less than the out-of-sync threshold, the out-of-sync counter oos_counter is incremented by 1; if Qc is greater than the synchronization threshold, the out-of-sync counter oos_counter is cleared to 0; if Qc is between the out-of-sync threshold and the synchronization threshold, the out-of-sync counter oos_counter is neither incremented nor cleared and remains unchanged. When the out-of-sync counter oos_counter reaches a 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 evaluation, subsequent periodic link quality evaluations are performed with the link evaluation indication interval P as the step size. In this example, P = 20 ms is used to illustrate the implementation process of this example. Subsequently, each time a link quality evaluation is performed, it is necessary to first perform a measurement mode switching judgment and then perform a link quality evaluation.

[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 out-of-step threshold, switch to the fast measurement mode; among them, the RLM measurement frequency corresponding to the fast measurement mode is to perform an RLM measurement every 5 ms, and write the RLM measurement value at each RLM measurement opportunity into the Buffer. When the link evaluation indication interval of 20 ms is reached, perform a link quality evaluation, 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 monitored measurement values obtained at each RLM measurement opportunity are cyclically written into the Buffer. The size of the Buffer is 20, then the first monitored measurement value is written into the first element of the Buffer; the second monitored measurement value is written into the second element of the Buffer;...; the 20th monitored measurement value is written into the 20th element of the Buffer; the 21st monitored measurement value is written into the first element of the Buffer; the 22nd monitored measurement value is written into the second element of the Buffer; and so on, following this rule and cycling continuously.

[0111] Step A3, when just switched to the fast measurement mode, the terminal will remain in the fast measurement mode for a period of time, that is, keep using the fast measurement mode for measurement (M * link evaluation indication interval P) ms = 6 * 20 ms = 120 ms. Within 120 ms, the terminal will perform at most 6 link quality evaluations, that is, compare with the out-of-step threshold at most 6 times. If during the execution of 6 link quality evaluations, the out-of-step counter oos_counter has reached 6 times, then the terminal will directly enter the pre-out-of-step state; otherwise, after completing 6 comparisons, then judge whether to switch the measurement mode according to the results of these 6 comparisons. At this time, the measurement mode switching criterion is: if the number of times greater than the synchronization threshold in the 6 comparison results accounts for 3 / 4 or more of the 6 times, then switch to the normal measurement mode; otherwise, continue to maintain the fast measurement mode.

[0112] If the fast measurement mode continues to be maintained, then the link quality assessment for the next 120 ms is continued. That is, within the next 120 ms, the fast measurement mode is maintained for measurement. During this 120 ms, the terminal performs at most 6 more link quality assessments. If the out-of-sync counter oos_counter reaches 6 times during the execution of the 6 assessments, then the terminal will directly enter the pre-out-of-sync state; otherwise, 6 comparisons will be completed, and then it will be determined whether to switch the measurement mode based on the results of the 6 comparisons. If the fast measurement mode is selected again at this time, then the above process will continue to be repeated, that is, the link quality assessment will be performed using the fast measurement mode within the next 120 ms; if the normal measurement mode is selected at this time, then the link measurement will be performed according to the normal measurement mode, and after completing one link quality assessment, it will be determined whether to switch the measurement mode according to the first preset condition.
