Compared with the prior art, the technical scheme of the embodiment of the invention has the following beneficial effects:
the embodiment of the invention provides a method for controlling an idle mode of a terminal, which comprises the following steps: in an idle mode, determining the mobility state of each frequency point according to the change of the signal quality of each frequency point in a first time period; determining an initial detection period of each frequency point; and updating the initial detection period of each frequency point according to the mobility state of the frequency point to obtain the current detection period of the frequency point, so as to detect and measure the neighbor cell of the frequency point according to the current detection period. Compared with the prior art, the scheme of the embodiment of the invention can determine the initial detection period of each frequency point according to the historical motion condition of the terminal and the motion condition of each frequency point when the method is started. And then monitoring the mobility state of each frequency point in each first time period in real time so as to update the initial detection period according to the change of the mobility state of each frequency point. The specific updating can be that for the frequency point with weak mobility, the adjacent cell detection and measurement are not needed to be carried out frequently, the period of carrying out the adjacent cell detection and measurement on the frequency point can be prolonged, and the power consumption can be effectively reduced. And for the frequency point with stronger mobility, the period for detecting and measuring the adjacent cell can be shortened. Thus, the mobility and power consumption requirements of the terminal can be balanced.
Further, if the resolving capability of the terminal in the current service cell does not meet the resolving requirement, triggering neighbor cell detection and measurement of all frequency points to perform cell reselection, so as to avoid that the terminal cannot perform cell reselection in time and influence communication of the terminal because the current detection period time of each frequency point is long when the terminal is in an Idle state.
Further, after triggering the cell reselection evaluation, the detection period of the frequency point is updated, the update condition of the detection period is related to various factors (such as the mobility of the current serving cell, the mobility of each frequency point, etc.), and the update mode of the detection period of the frequency point is different (such as expanding or reducing the current detection period). Therefore, the frequency of the terminal for detecting and measuring the adjacent cells of each frequency point can be controlled, so that the mobility and the power consumption of the terminal can be flexibly balanced, and the signal quality of the terminal is not affected.
Further, the terminal may determine whether to reach a time point when each frequency point performs neighbor cell detection and measurement by counting the experienced DRX cycles by converting the current detection cycle of each frequency point into a positive integer multiple of the DRX cycle.

Detailed Description
As described in the background art, in the prior art, reasonable choice of mobility and power consumption of a terminal in different application scenarios cannot be guaranteed.
Specifically, the terminal mainly performs two types of tasks in the idle mode: 1. receiving paging information; 2. and ensuring mobility (such as neighbor detection and measurement, etc.). In addition to handling both tasks, the terminal will enter a sleep mode. Thus, the longer the processing time of the above two tasks, the greater the power consumption of the terminal.
Referring to fig. 1, fig. 1 is a schematic diagram of state switching of a terminal in a DRX cycle in the prior art, where each DRX cycle includes a sleep period (also referred to as a sleep state) and an active period, and the terminal performs operations such as paging message (paging) reception, neighbor cell detection, and measurement in the active period.
For task 1, the reception of paging information needs to be based on better reception quality of the camping cell signal, the higher the signal quality, the higher the paging reception reliability. For the task 2, the guarantee of the signal quality of the resident cell needs better terminal mobility, the better the cell mobility is, the more frequent neighbor cell detection and measurement are needed to be used as the guarantee, so that the terminal can quickly reflect the change of the surrounding environment, and the cell with the best signal quality in the current coverage area can be selected as the resident cell at the first time, thereby more effectively guaranteeing the analysis and reception of paging. However, the more frequent neighbor detection and measurement is performed, the more the terminal power consumption increases dramatically.
In summary, the two indexes of mobility and power consumption exist in contradiction in idle mode. Along with increasingly obvious difference of application demands of consumers, the mobile terminal modes are more and more different, and the application scene of the mobile terminal is more and more complex. The contradiction between mobility and power consumption of the terminal in the idle mode can specifically distinguish the terminal according to application scenes: the main stream application scene of the first type of terminal is in a low-speed or static state, the quality change of peripheral signals of the terminal in unit time is small, the terminal has low requirements on mobility, but has high requirements on power consumption indexes of the terminal; the conventional application scene of the second type of terminal is a complex high-speed motion state or a state with relatively large motion speed change, the quality change of peripheral signals of the terminal in unit time is relatively large, and the terminal has high requirements on mobility but is relatively insensitive to the power consumption requirement of the terminal. It is apparent that these two types of terminals should be somewhat targeted for differences in the underlying design.
Conventionally, existing terminals reduce the task interval for mobility security by detecting and measuring neighbor cells according to protocol advice values. Obviously, if the application scene of the terminal is in the low-speed or static state described above, the change speed of the surrounding neighbor cells is very slow, and if the terminal is controlled according to the fixed period, the terminal has no great significance on mobility, and the power consumption burden of the terminal is increased to a certain extent; if the application scenario of the terminal is the complex high-speed motion state described above, the change speed of the surrounding neighbor cells is particularly fast, especially as the complexity of the existing network networking environment increases, if mobility control is performed according to the fixed period, the signal change speed may exceed the expectation, so that the paging reception is seriously affected, which is reflected in the decrease of the user perception.
Taking LTE as an example, a series of protocols of 3gpp 36.133, which specify serving cell measurements (Measurement of serving cell), intra-frequency measurements of evolved universal terrestrial radio access network (evolved universal terrestrial radio access network, E-UTRAN) cells, inter-frequency measurements of E-UTRAN cells, etc., describe idle mode terminal mobility scheduling control.
In general, the existing terminal detects and measures the neighbor cell according to the recommended value of the protocol, or reduces the interval of tasks executed by the terminal in idle mode for mobility guarantee. Obviously, if the application scene of the terminal is in the low-speed or static state described above, since the change speed of the surrounding neighbor cells is very slow, if the terminal is controlled according to the fixed period, the terminal has no great significance on mobility, and the power consumption burden of the terminal is increased to a certain extent. If the application scenario of the terminal is the complex high-speed motion state described above, the change speed of the surrounding neighbor cells is particularly fast, especially as the complexity of the existing network networking environment increases, if mobility control is performed according to the fixed period, the signal change speed may exceed the expectation, so that the paging reception is seriously affected, which is reflected in the decrease of the user perception.
In order to solve the above problems, an embodiment of the present invention provides a method for controlling an idle mode of a terminal, including: in an idle mode, determining the mobility state of each frequency point according to the change of the signal quality of each frequency point in a first time period; determining an initial detection period of each frequency point; and updating the initial detection period of each frequency point according to the mobility state of the frequency point to obtain the current detection period of the frequency point, so as to detect and measure the neighbor cell of the frequency point according to the current detection period.
Thus, the mobility and power consumption requirements of the terminal can be balanced.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 2, fig. 2 is a flow chart of an idle mode control method of a terminal according to an embodiment of the present invention, where the idle mode control method of the terminal may be executed by a terminal side, and the terminal side may refer to terminal devices such as a computer, a mobile phone, a smart watch, etc., and the method includes:
step S201, in an idle mode, determining the mobility state of each frequency point according to the change of the signal quality of each frequency point in a first time period;
the method of the embodiment of the invention aims at improving the neighbor cell detection and measurement of the terminal in Idle mode in the prior art. The method detects the mobility state of each frequency point where a plurality of adjacent cells of the terminal are located in the Idle mode. A frequency bin may correspond to one or more neighbors.
The mobility state of a frequency point is used for describing the mobility strength of the frequency point, and the mobility state of a certain frequency point can be represented by the movement speed of the frequency point.
Optionally, a maximum value and a minimum value of the signal quality of each frequency point in the first time period are obtained, and the change of the signal quality of each frequency point is determined through the difference value between the maximum value and the minimum value.
The first period (the time length may be referred to as the ObserveTimer 1) is a preset detection time. The first period may include one or more DRX cycles, and the maximum value and the minimum value of the signal quality of each frequency point in the first period are obtained through neighbor cell detection and measurement, so as to determine the change of the signal quality of each frequency point.
Optionally, the obtaining the maximum value and the minimum value of the signal quality of each frequency point in the first period, and determining the change of the signal quality of each frequency point according to the difference between the maximum value and the minimum value includes: obtaining the maximum value and the minimum value of the signal quality of each adjacent cell in the first time period, and calculating the difference value between the maximum value and the minimum value of the signal quality of each adjacent cell to determine the change of the signal quality of each adjacent cell; and determining the change of the signal quality of each frequency point according to the change of the signal quality of a plurality of adjacent cells corresponding to each frequency point.
In each DRX period, signals of each adjacent cell can be received through adjacent cell detection and measurement, so that the signal quality of each adjacent cell can be obtained.
And counting the past length of each adjacent cell from the current judging moment as the maximum value and the minimum value of the signal quality of each cell in the first time period of the ObserveTimer 1. The signal quality of each cell may be characterized by a signal strength indicator, such as reference signal received power (Reference Signal Receiving Power, RSRP for short), reference signal received quality (Reference Signal Receiving Quality, RSRQ for short), etc., or other parameters for indicating the signal quality of each neighbor cell may be used.
When the signal quality of each cell is characterized by RSRP, the maximum RSRP and the minimum RSRP of a cell in a first period of time may be denoted as MaxRSRP, minRSRP, respectively.
Although neighbor cell detection and measurement are performed with respect to a cell, in practice, the monitoring of a moving state is performed with respect to a frequency point, so that signal qualities of different cells in the same frequency point need to be combined to obtain a change in signal quality of the frequency point.
Alternatively, the difference between the maximum value and the minimum value of the signal quality of each neighboring cell may be calculated, the mobility state of each neighboring cell is represented by the difference, and the mobility state of the neighboring cell with the largest absolute value of the difference of the neighboring cells of the same frequency point is used as the mobility state of the frequency point.
Optionally, the first period includes a plurality of second periods, and the obtaining a maximum value and a minimum value of signal quality of each neighboring cell in the first period includes: and obtaining the maximum value and the minimum value of the signal quality of each adjacent cell in a plurality of continuous second time periods to obtain the maximum value and the minimum value of the signal quality of each adjacent cell in the first time period.
Because the number of the measured neighbor cells is large, and the measured value samples corresponding to each cell are also large in the observation period ObserveTimer1, if each measured value corresponding to each cell is stored, and evaluation is performed after the observation of the first period is completed, a large storage space is required to store the detected signal quality (such as RSRP value) of each neighbor cell. In order to save the storage space, a simplified processing can be performed, that is, a sliding window processing mode can be adopted, that is, only the signal quality detected by each neighboring cell in a smaller second time period (denoted as an ObserveTimer 2) is stored each time, and then the maximum value and the minimum value of the signal quality are taken and stored after the observation of the second time period is completed. The first period of time ObserveTimer1 includes a number (denoted as a) of second periods of time ObserveTimer2, where a=observetimer 1/ObserveTimer2. And then, counting the maximum value and the minimum value of the signal quality of each adjacent cell in the A second time periods in the first time period to obtain the maximum value and the minimum value of the signal quality of each adjacent cell in the first time period. Alternatively, the value of the ObserveTimer2 may be set based on the memory space available to the terminal.
Referring to fig. 3, fig. 3 is a schematic diagram of a method for obtaining a maximum value and a minimum value of signal quality of a neighboring cell in a first period of time; the maximum value of the signal quality of a certain neighboring cell corresponding to each of the first time periods ofoservetimer 1 is respectively Max1, max2, max3 and Max4, and the minimum value of the signal quality of a certain neighboring cell corresponding to each of the oservetimer 2 is respectively Min1, min2, min3 and Min4, and the maximum value Max of the signal quality and the minimum value Min of the signal quality of the neighboring cell in the first time period ofoservetimer 1 are obtained according to the maximum value and the minimum value of the signal quality of the 4 oservetimer 2 in fig. 3.
Optionally, the mobility state of each frequency point includes that the mobility of the frequency point is low-level, medium-level or high-level, wherein if the difference between the maximum value and the minimum value of the signal quality of a frequency point is greater than the first signal threshold in the first time period, the mobility of the frequency point is high-level; if the difference between the maximum value and the minimum value of the signal quality of a frequency point is smaller than the second signal threshold value in the first time period, the mobility of the frequency point is low; if the difference between the maximum value and the minimum value of the signal quality of a frequency point in the first time period is greater than the second signal threshold and less than the first signal threshold, the mobility of the frequency point is a medium level.
The first signal threshold and the second signal threshold are preset thresholds for judging the mobility state of the frequency point based on the difference value, and specific values of the preset thresholds can be set according to requirements. When the signal quality is characterized by RSRP, the first signal threshold may be denoted RSRPChangeTh1 and the second signal threshold may be denoted RSRPChangeTh2.
When MaxRSRP-MinRSRP > RSRPChangeTh1, the mobility of the frequency point is High; when MaxRSRP-MinRSRP < RSRPChangeTh2, the mobility of the frequency point is high (Low); in other cases, the mobility of the frequency point is Medium.
Further, with continued reference to fig. 2, the method of this embodiment further includes: step S202, determining an initial detection period of each frequency point;
the initial detection period is a detection period for starting to detect and measure the neighboring cells set for the neighboring cells of each frequency point, and the initial detection periods of the neighboring cells of each frequency point can be the same or different.
Alternatively, the determination of the initial detection period of each frequency point is only performed at the beginning of the idle mode control method of the terminal according to the embodiment of the present invention, for example, may be performed in the first DRX cycle after the terminal is powered on. After the initial detection period of each frequency point is determined, the determined initial detection period can be stored at the terminal side.
Optionally, the initial detection period of each frequency point may be determined according to the following steps: calculating estimated residence time in the current service cell according to residence time of one or more service cells in history residence; and determining the initial detection period of each frequency point according to the estimated residence time.
Wherein, the number of cells resided in the last preset time period (recorded as the ObserveTimer 3) of the terminal is obtained and recorded as M, and the residence time of the M residence cell terminals is obtained and respectively recorded as [ cell duration ] M ,CellDuration M-1 ,...,CellDuraotin 2 ,CellDuration 1 ]The method comprises the steps of carrying out a first treatment on the surface of the Wherein, cellduration 1 For the residence time of the first cell in the ObserveTimer3 of the terminal, the cell duration 2 For the residence time of the terminal in the second cell in the ObserveTimer3, and so on, the cell duration M The residence time of the Mth cell in the ObserveTimer3 is the residence time of the terminal.
The residence time curve fitting the historical residence time curves of the cells can be used for fitting, then the estimated residence time of the latest residence cell is obtained and is recorded as the cell duration 0 。
The estimated residence time can predict how long the terminal will reselect to the new cell, and the initial detection period of the detection and measurement of the neighbor cell can control the terminal to detect and measure the neighbor cell at a lower frequency before reselecting to the new cell.
By setting the initial detection period of each frequency point by estimating the residence time, the conventional motion condition of the terminal and the movement condition of each cell can be considered when the initial detection period of each frequency point is set.
Optionally, the initial detection period of each frequency point is determined according to the estimated residence time according to the following formula (1):
wherein T is measure For the initial detection period, N2 represents the mapping relation between a cell detection and the cell measurement, and the value of the mapping relation is a preset constant, T detect Can be calculated according to the following formula (2):
wherein t_reselection is a preconfigured Reselection evaluation duration of a frequency point/cell, N1 is a detection number in a period of residing a cell, and the detection number is a preset constant, and the value is Cellduration 0 For the estimated residence time length, T detect Th1 is the minimum period, T detect Th2 is the maximum period, T detect _Th1、T detect The value of Th2 is a preset constant. Max () is the maximum value of the bracketed content, and min () is the minimum value of the bracketed content.
By the algorithm of the above formula (2), by T detect Th1 and T detect Th2 defines T detect And T measure The lower limit and the upper limit of the value of the number of times of detecting and measuring the neighbor cell by the terminal in the residence period of the current cell are not too high or too low, so that the situation that the power consumption of the terminal is too high due to too many detection times can be avoided, and the situation that the terminal cannot update the detection and measurement results of the neighbor cell in time due to too few detection times can be avoided, and the communication of the terminal is affected.
Further, with continued reference to fig. 2, the method of this embodiment further includes: step S203, for each frequency point, updating the initial detection period according to the mobility state of the frequency point to obtain the current detection period of the frequency point, so as to perform neighbor detection and measurement on the frequency point according to the current detection period.
After the mobility state of each frequency point is obtained in step S201, the detection period of neighbor cell detection and measurement of the cell of each frequency point may be updated according to the change of the mobility state of each frequency point in each first time period, and the updated detection period is the current detection period.
By the idle mode control method of the terminal of fig. 2, when the method is executed, the initial detection period of each frequency point can be determined according to the historical motion condition of the terminal and the motion condition of each frequency point. And then monitoring the mobility state of each frequency point in each first time period in real time so as to update the initial detection period according to the change of the mobility state of each frequency point. The specific updating can be that for the frequency point with weak mobility, the adjacent cell detection and measurement are not needed to be carried out frequently, the period of carrying out the adjacent cell detection and measurement on the frequency point can be prolonged, and the power consumption can be effectively reduced. And for the frequency point with stronger mobility, the period for detecting and measuring the adjacent cell can be shortened. Thus, the mobility and power consumption requirements of the terminal can be balanced.
In one embodiment, the idle mode control method of the terminal may further include: monitoring the resolving power of the current service cell according to the received paging message; when the analysis capability of the current service cell is detected to not meet the analysis requirement, triggering neighbor cell detection and measurement of all frequency points to reselect the cell.
The current serving cell is the cell in which the terminal currently resides. In each DRX cycle, the terminal receives reception of a paging message (paging) to monitor the resolution capability of the current serving cell. Optionally, when the signal quality of the current serving cell is smaller than a preset threshold, the parsing capability of the current serving cell may be considered to not meet the parsing requirement. At this time, the terminal communication may be affected by the continued stay in the current serving cell, and the terminal needs to perform cell reselection.
Alternatively, if the signal quality of the current serving cell has made it difficult to ensure the reliability of the paging message reception, the parsing capability of the current serving cell is considered to be insufficient for the parsing requirement.
As can be seen from the foregoing steps, the terminal performs two neighbor cell detection and measurement on the cells of each frequency point, and must be separated by a certain period of time, that is, the current detection period, where the period of time may have a span of several or even tens of DRX cycles, and although the mobility performance is ensured as much as possible by the initial detection period determined in step S202 in fig. 2 according to the estimated residence time of the cells, the initial detection period determined by this method is still macroscopic and is based on statistics, and cannot cover all the scenes of the terminal movement. For example, if a terminal is in a complex mobile environment at a certain moment, a valid cell may exist in a certain time gap from the occurrence to the completion of reselection. In this period, the signal of the current serving cell just fades fast, so that the signal quality of the current serving cell in this period cannot be guaranteed, if the paging message is received in this period, the reception omission of the paging message will be necessarily caused, and the communication experience of the user in this period is affected. Based on this, it is necessary to determine the receiving condition of the paging message of the current serving cell in this scenario, so as to trigger the emergency blind detection measurement of the cell at the edge position where the resolving capability of the current serving cell cannot meet the receiving requirement of the paging message, so as to trigger the detection and measurement of the neighboring cells of all the frequency points.
Optionally, the time interval for triggering neighbor cell detection and measurement of all frequency points twice is greater than or equal to the triggering time threshold.
In one embodiment, when it is detected that the resolution capability of the current serving cell does not meet the resolution requirement, the neighbor cell detection and measurement of all the frequency points are triggered if the following conditions are simultaneously met: the maximum value of the signal quality of all the frequency points is smaller than a reselection signal threshold, the mobility of the current service cell is high-grade or medium-grade, and the time length from the detection and measurement of the neighbor cell of all the frequency points triggered last time is greater than or equal to the triggering time threshold; wherein, the mobility of the current service cell includes high, medium and low levels according to the speed of the current service cell.
Alternatively, the moving speed of the current serving cell may be determined according to paging messages received in each DRX cycle. In mobility of the current serving cell, a relationship between the moving speed of the current serving cell may be expressed as: high level > medium level > low level.
When the resolving capability of the current service cell is considered to not meet the resolving requirement, and meanwhile, the cells meeting the reselection condition are not detected by carrying out neighbor cell detection and measurement on the cells of all the frequency points, so that the emergency cell blind detection measurement on the cells of all the frequency points is necessarily triggered, better cell residence is quickly found, and the reliable receiving of the subsequent paging message is ensured. However, to avoid frequent false triggering of the mechanism, which leads to an unnecessary increase in power consumption, a silence timer needs to be added, so that the interval between two triggers of the mechanism must be greater than a certain duration, i.e. the trigger time threshold.
When the following 4 conditions are satisfied at the same time, triggering the emergency cell detection and cell measurement of all the frequency points:
1. in the continuous bserveCounterTh DRX periods, the maximum value (MaxSinr) of the signal quality detected by the terminal for neighbor detection and measurement of all frequency points is smaller than a preset reselection signal threshold (marked as SinrTh 1), or the maximum value (MaxSinr) of the signal quality detected by the last time of triggering the cell emergency blind detection is smaller than the preset reselection signal threshold (marked as SinrTh 1). The preset reselection signal threshold SinrTh1 may be a signal-to-noise ratio threshold where reliability of paging information reception is difficult to ensure, and the value of SinrTh1 may be determined based on a simulated paging manner, for example, sinrTh1 may be set to 95% of signal quality capable of reliably receiving paging information. The observeCounterTh is the number of observation periods of which the reliability of paging message reception is difficult to guarantee, and the value of the observeCounterTh is a preset value, wherein the value is set to be related to the DRX number of one-time paging configuration of the UI.
2. The mobility of the current serving cell is higher than Low, i.e. the mobility of the current serving cell is either High or Medium.
3. The time interval from the last triggering of the cell emergency blind detection measurement is greater than or equal to a triggering time threshold (silntwin), and the value of the silntwin is preset based on balancing the mobility and the power consumption of the terminal.
4. The signal quality (ServSinr) of the current serving cell is less than the threshold of the preset signal quality (SinrTh 2) or the signal quality (ServSinr) of the current serving cell in this DRX cycle is less than the signal quality (servsinhis) of the current serving cell in the last DRX cycle. The threshold of the preset signal quality (SinrTh 2) is determined according to the edge position of the terminal for receiving the paging message, where SinrTh2 may be a signal-to-noise ratio threshold where the reliability of receiving the paging message is difficult to ensure, and the value setting of SinrTh2 may be determined based on the simulated paging mode, for example, sinrTh2 may be set to be 50% of the signal quality capable of reliably receiving the paging message.
In this embodiment, if the resolving capability of the terminal in the current serving cell does not meet the resolving requirement, the neighbor cell detection and measurement of all the frequency points are triggered to perform cell reselection, so as to avoid that the terminal cannot perform cell reselection in time and influence the communication of the terminal because the current detection period time of each frequency point is long when the terminal is in the Idle state.
In one embodiment, please refer to fig. 4, fig. 4 is a partial flow chart of an idle mode control method of a terminal; after triggering the neighbor detection and measurement of all the frequency points, executing step S401, and detecting whether each frequency point meets the reselection evaluation condition of network configuration;
If the detection result in step S401 is yes, step S402 is executed to enter a cell reselection evaluation period, and the current detection period of the frequency point satisfying the reselection evaluation condition of the network configuration is modified to be a DRX period.
If the detection result in step S401 is no, the detection is continued. Whether neighbor detection and measurement of all frequency points are triggered again can be judged according to the conditions.
If a frequency point is detected to meet the Reselection evaluation condition of network configuration in a DRX period, entering a Reselection evaluation period t_Reselection, and carrying out initial detection period T of the frequency point measure And modifying the frequency point to be a DRX period, namely, the current detection period of the frequency point is the DRX period, so as to evaluate whether the frequency point meets the cell reselection condition according to the DRX period. In the prior art, the cell reselection comprises four steps: measuring, evaluating, triggeringThe initial detection period and the current detection period in the embodiment of the present invention are both for the first step of cell reselection, i.e. measurement, and the cell reselection evaluation mentioned in the embodiment is the second step, i.e. evaluation, and the evaluation conditions and the execution steps can be according to the scheme related to cell reselection evaluation in the prior art.
In one embodiment, after entering the cell reselection evaluation period, further comprising: step S403, judging whether to execute cell reselection with respect to the frequency point;
if the determination result in step S403 is yes, cell reselection is performed.
If the judgment result in the step S403 is no, executing the step S404, recording the frequency point as a frequency point to be updated, and determining an initial detection period of the frequency point to be updated; referring to fig. 2 again, the initial detection period of the frequency point to be updated is determined again according to the operation of step S202.
And continuing to execute step S405, to determine whether the frequency point to be updated is a high priority frequency point;
the priority of each frequency point is configured by a network, the frequency point with high priority is selected in the cell reselection priority, and the information of the network configuration can be queried to determine whether the frequency point to be updated is the frequency point with high priority.
And when the frequency point to be updated is a high-priority frequency point, continuing to execute the step S406, judging whether the mobility of the current service cell is low and the mobility of the frequency point to be updated is low, and when the judgment result of the step S406 is yes, continuing to execute the step S407, and not performing the detection and measurement of the starting neighbor cell of the frequency point to be updated.
If the frequency point to be updated is a high priority frequency point, although the protocol suggests that each DRX cycle performs neighbor cell detection and measurement on the cell corresponding to the frequency point, it is obviously unnecessary for the targeted selection in the application scenario, since mobility control is not further continued as long as the current serving cell can continue to camp.
If the mobility of the current serving cell and the frequency point to be detected is low, the signal quality of the terminal is relatively stable in a short period, and the starting of the neighbor cell detection and measurement on the frequency point to be updated is stopped.
If the judgment result in the step S406 is no, the step S408 is executed, the neighbor cell detection and measurement are performed on the cell to be updated with the frequency point according to the initial detection period of the frequency point to be updated, and the mobility of the current serving cell is continuously monitored;
step S409, when the mobility of the current service cell is monitored to be low, the detection period of the frequency point to be updated is increased. At this time, the detection period of the frequency point to be updated is the initial detection period of the frequency point, and optionally, the current detection period of the frequency point can be enlarged to 2 times of the initial detection period.
Step S410, when the mobility of the current service cell is high, the detection period of the frequency point to be updated is reduced. At this time, the detection period of the frequency point to be updated is the initial detection period of the frequency point, and optionally, the current detection period of the frequency point can be reduced to half of the initial detection period. Alternatively, a minimum detection period threshold (Timer 1) may be set, and the minimum value thereof is limited to be not smaller than the detection period threshold Timer1 when the detection period of the frequency point to be updated is reduced.
In addition, when the mobility of the current serving cell is monitored to be medium, the detection period of the frequency point to be updated is kept unchanged as the initial detection period.
In one embodiment, after determining whether the frequency point to be updated is a high priority frequency point in step S405, the method further includes: when the frequency point to be updated is a frequency point with a non-high priority, executing step S411, and judging whether the mobility of the current serving cell is low;
if the determination result in step S411 is yes, step S412 is executed, and the neighbor detection and measurement are not performed for the frequency point to be updated.
If the judgment result in the step S411 is no, the step S413 is executed, the neighbor cell detection and measurement are carried out on the cell of the frequency point to be updated according to the initial detection period of the frequency point to be updated, and the mobility of the current service cell is monitored again;
step S414, when the mobility of the current service cell is monitored to be medium, the detection period of the frequency point to be updated is increased.
At this time, the detection period of the frequency point to be updated is the initial detection period of the frequency point, and optionally, the current detection period of the frequency point can be enlarged to 2 times of the initial detection period.
In step S415, when the mobility of the current serving cell is high, the detection period of the frequency point to be updated is reduced.
At this time, the detection period of the frequency point to be updated is the initial detection period of the frequency point, and optionally, the current detection period of the frequency point can be reduced to half of the initial detection period. Alternatively, a minimum detection period threshold (Timer 1) may be set, and the minimum value thereof is limited to be not smaller than the detection period threshold Timer1 when the detection period of the frequency point to be updated is reduced.
In addition, when the mobility of the current serving cell is monitored to be low, the detection period of the frequency point to be updated is kept unchanged as the initial detection period.
By the idle mode control method of the terminal described in fig. 4, after triggering the cell reselection evaluation, the detection period of the frequency point is updated, where the update condition is related to various factors (such as mobility of the current serving cell, mobility of each frequency point, etc.), and the update manner of the detection period of the frequency point is different (such as expanding or reducing the current detection period). Therefore, the frequency of the terminal for detecting and measuring the adjacent cells of each frequency point can be controlled, so that the mobility and the power consumption of the terminal can be flexibly balanced, and the signal quality of the terminal is not affected.
In one embodiment, the current detection period includes M DRX periods, where M is a positive integer.
Optionally, the detecting and measuring the neighboring cell of each frequency point according to the current detection period includes: every time a DRX period of a frequency point passes, the counter value corresponding to the frequency point is increased by 1; and when the counter value is greater than or equal to M, performing neighbor detection and measurement on the frequency point, and emptying a counter corresponding to the frequency point.
The initial detection period and the current detection period of a frequency point are positive integer times of DRX, namely M times. The terminal may count the DRX cycles that are experienced by the terminal for the calculation of the current detection cycle of a frequency point, and when the counter value > =m, trigger neighbor detection and measurement of the cell of the frequency point. And (5) emptying the counter of the frequency point and continuing counting of the next detection period.
Optionally, referring to fig. 4 again, when step S407 and step S412 in fig. 4 do not perform detection and measurement of the frequency point start neighbor to be updated, the counter corresponding to the frequency point is paused at the same time, and when the condition of starting in step S407 or step S412 is not satisfied, the counter corresponding to the frequency point is started again.
In addition, when the step S408 and the step S413 perform neighbor detection and measurement on the cell of the frequency point to be updated according to the initial detection period of the frequency point to be updated, when the counter value > =m of the frequency point to be updated is detected, the neighbor detection and measurement on the cell of the frequency point is triggered, and the counter is cleared. And if the counter value < M of the frequency point to be updated is detected, continuing to count the counter +1 according to the DRX cycle.
Optionally, the detection and measurement of each frequency point can be performed separately, and the period of the detection of each frequency point and the period of the measurement of each frequency point are the same, i.e. the current detection period.
In this embodiment, the current detection period of each frequency point is converted into a positive integer multiple of the DRX period, and the terminal may determine whether to reach a time point when each frequency point performs neighbor cell detection and measurement by counting the experienced DRX periods.
Referring to fig. 5, fig. 5 is a timing chart of terminal state switching, in which a detection period for performing neighbor detection and measurement by each frequency point is determined according to characteristics of each frequency point, so that time periods for performing neighbor detection and measurement in each DRX period are different, and three DRX periods (DRX 1, DRX2, and DRX3 are illustrated as an example). With the terminal in Idle mode, cell reselection may be performed during neighbor Cell detection and measurement (Cell reselection by the history resident Cell0 in fig. 5 to access the new resident Cell 1).
