Description

Control method, device and system

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a control method, apparatus, and system.

Background

Establishment of Carrier Aggregation (CA) or Dual Connectivity (DC) is achieved by a base station configuring a secondary cell (SCell) or a primary cell (PSCell) to a User Equipment (UE). Generally, before configuring an SCell or a PSCell, a base station configures the UE to measure a Reference Signal Received Power (RSRP) or a Reference Signal Received Quality (RSRQ) value of a frequency point where the potential SCell or PSCell is located, and then determines whether to configure the SCell or PSCell for the UE or which cell is configured as the SCell or PSCell according to a measurement result.

For New Radio (NR), NR supports fast establishment of CA or DC through early measurement (early measurement) of the UE. The basic idea is that the UE measures a frequency point of a potential secondary cell (SCell) or primary secondary cell (PSCell) in an idle (idle) or inactive (inactive) state, and after obtaining a measurement result, when the UE enters a connected state, the measurement result may be directly reported to the base station, so that the base station can rapidly configure the SCell or PSCell for the UE (for convenience of subsequent description, this measurement mode is defined as "advanced measurement").

Normally, in idle or inactive state, the UE needs to reselect a primary cell (PCell) for performing neighbor cell measurement, so as to determine the PCell serving the UE as the best cell (for convenience of subsequent description, such measurement is defined as "reselection measurement").

The target frequency point configured by the network and measured in advance may be the same as or different from the target frequency point measured by reselection, and the measurement in advance is divided into:

-overlaying carrier: the frequency point measured in advance is also the frequency point for reselecting and measuring the UE is measuring

-Non-overlapping carrier: the frequency point measured in advance is not the reselective measurement frequency point measured by the UE

Because the resource of the UE for measuring the frequency points is limited, the time required by the UE for measuring one frequency point is related to the number of the frequency points to be measured. For example, the time requirement for the UE to measure a single frequency point is 1s, and when the UE configures 3 measurement target frequency points, the measurement time requirement for each frequency point is 3 s.

If the channel condition of the service cell of the UE is better, the probability of reselection is lower, and from the power saving perspective, the terminal only performs reselection measurement on a high-priority target frequency point; if the channel condition of the serving cell is poor, the probability of reselection is high, and from the viewpoint of mobility, the terminal can normally perform reselection measurement on all target frequency points.

In the prior art, considering the influence of advanced measurement on reselection measurement, an example of controlling UE advanced measurement based on serving cell channel condition is given in documents R4-1915842 of Radio Access Network (RAN) 4# 93: when the channel condition of the serving cell is higher than a certain threshold, the UE performs normal advanced measurement on the frequency points measured in advance; when the channel condition of the serving cell is lower than the threshold, the UE does not perform advanced measurement or only performs partial advanced measurement on the frequency points measured in advance.

Furthermore, it is defined in Long Term Evolution (LTE) that the behavior of UE measurement in advance is also related to the channel condition of the serving cell: when the channel condition of the serving cell is good, the UE only performs advanced measurement on 1 frequency point which is measured in advance (wherein, 0-1 non-overlapping frequency point exists), and only performs one-time measurement; when the channel condition of a serving cell is poor, the UE performs advanced measurement on 3 frequency points measured in advance (0-1 of the frequency points are non-overlapping frequency points), wherein the overlapping frequency points are periodically measured, and the non-overlapping frequency points are measured at one time.

Although R4-1915842 and LTE both disclose that the number of frequency points measured in advance is controlled according to the conditions of a serving cell, how UE selects the frequency points measured in advance is not defined, and the frequency points measured in advance in the LTE are determined by the UE at present, so that the frequency points selected and measured by the UE are not the CA/DC frequency points which are most preferentially configured by a base station.

In addition, in NR, the base station may turn on a power saving function of the UE. The UE judges whether the UE is in any one or two states of low mobility and no cell edge according to the conditions configured by the base station. If so, relaxing the requirement of reselection measurement, for example, performing reselection measurement at longer time interval or not performing reselection measurement; if not, the requirement for reselection measurements is not relaxed.

In documents R4-1915295 of RAN4#93, it is proposed that advance measurement and power saving behavior need to be coordinated when a base station turns on UE power saving function, and 3 examples are given:

1) the UE does not enter a relaxation mode of the advance measurement under the condition that the advance measurement is configured;

2) when the UE is not at the edge of the cell, the UE is allowed to measure in advance, but the requirement of measurement in advance is relaxed;

3) when the early measurement related T331 timer is running, the UE does not enter the early measurement relaxation mode.

It can be seen that the prior art prioritizes only the advance measurements, sacrificing the possibility of UE power saving, and does not take into account the mobility state of the UE. However, if the UE is in a low mobility state, it is not necessary at all for the UE to drop power saving when measuring in advance.

Disclosure of Invention

The embodiment of the application provides a control method, a control device and a control system, and communication equipment performs relaxation measurement on a frequency point configured by a base station and measured in advance in order to ensure the performance of reselection measurement, so that the influence of the advance measurement on the reselection measurement is reduced.

In a first aspect, an embodiment of the present application provides a control method, executed by a communication device, where when the communication device is in an idle or inactive state, the method includes: receiving N frequency points which are configured by a base station and measured in advance and a set threshold value of Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ) which enters a relaxation mode which is measured in advance by each frequency point which is configured by the base station and measured in advance in at least one of normal measurement, relaxation measurement and non-periodic measurement, wherein N is a positive integer which is greater than zero; when the value of RSRP or RSRQ of a serving cell is smaller than the set threshold, determining the measurement behavior of each frequency point in the N frequency points measured in advance; and measuring each frequency point measured in advance according to the measuring behavior corresponding to each frequency point measured in advance.

In the invention, the UE can select different measurement behaviors for different frequency points according to the modes of different frequency points, such as measurement capability, priority sequencing and the like, by relaxing the advanced measurement, so that the aim of relaxing all the frequency points which are measured in advance is achieved, and the advanced measurement is ensured to be rapidly completed on the premise of not influencing the performance of reselection measurement.

In one embodiment, the determining the measurement behavior of each of the N frequency points measured in advance includes: and determining M frequency points measured in advance to perform the normal measurement, R frequency points measured in advance to perform the relaxation measurement and S frequency points measured in advance to perform the non-periodic measurement, wherein M, R and S are positive integers larger than zero.

In one embodiment, the determining the measurement behavior of each of the N frequency points measured in advance includes: and determining a first type of frequency point measured in advance to perform normal measurement, a second type of frequency point measured in advance to perform relaxation measurement and a third type of frequency point measured in advance to perform non-periodic measurement according to the type of each frequency point measured in advance, wherein the type of each frequency point measured in advance comprises the first type, the second type and the third type.

In the invention, the UE can select different measurement behaviors for different frequency points according to the measurement capability and the priority sequence of the frequency points, thereby achieving different measurement performances and ensuring that the high-priority frequency points can finish measurement quickly. Since the high-priority frequency point corresponds to the PSCell or SCell that the UE is more likely to add, the UE is more likely to be added with CA and DC quickly when entering a connected state.

In one embodiment, the determining the measurement behavior of each of the N frequency points measured in advance includes: determining the number M of the frequency points measured in advance through normal measurement, the number R of the frequency points measured in advance through relaxation and the number S of the frequency points measured in advance through non-periodic measurement, wherein M, R and S are positive integers larger than zero; determining the priority of each frequency point of the N frequency points measured in advance according to the type of each frequency point measured in advance; and performing the normal measurement on the first M frequency points with the highest priority and measured in advance, performing the relaxation measurement on the first R frequency points with the highest priority and measured in advance except the frequency points with the highest priority and measured in advance, and performing the non-periodic measurement on the first S frequency points with the highest priority and measured in advance except the frequency points with the highest priority and measured in advance.

In the invention, the UE can normally measure the frequency points with high priority, make the frequency points with next high priority loose and make the frequency points with poor priority not make periodic measurement according to the number of various measurement actions and the priority sequence of the frequency points, thereby ensuring the advanced measurement of the important frequency points without influencing the reselection measurement.

and K is a relaxation factor, M is the number of the frequency points measured in advance for the normal measurement, and L is the number of the reselection measurement.

In one embodiment, the relaxation factor N2 that determines the measurement time requirement for the relaxation measurement is:

In the invention, the reason that the UE does not immediately enter the advanced measurement immediately after entering the idle state or the inactive state or after finishing the reselection measurement is that the UE is ensured not to enter the relaxed mode of the advanced measurement and not to influence the reselection measurement.

In the invention, when the UE is in a node mode and in a low mobility state, the potential PSCell and SCell of the UE are generally not changed, and in this case, the advance measurement can realize power saving without influencing the rapid establishment of CA and DC. When the UE performs reselection measurement (is not in low mobility and/or in a cell edge state), potential PSCell and SCell may also change due to a change in a serving cell, and at this time, measurement results of the potential PSCell and SCell are quickly obtained, so that it can be ensured that the UE enters a connected state soon after the reselection measurement, and CA and DC are quickly established.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Fig. 1 is a flowchart of a control method according to an embodiment of the present disclosure. As shown in fig. 1, when the UE is in idle or inactive state, the UE performs the following steps:

step S103, receiving N frequency points which are configured by the base station and measured in advance and a set threshold value of Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ) which enters a relaxation mode of measurement in advance.

Before configuring the measurement frequency point for the UE in advance, the base station needs to determine whether the UE is in the power saving mode. The UE therefore also needs to perform the following steps:

step S101, receiving first parameter information sent by the base station.

The first parameter information is for the UE to determine whether the UE is in the node mode. When receiving the first parameter information, the UE determines whether it is in the power saving mode, and if it is in the node mode, then performs step S103.

In order to enable the UE to be in a connected state, the base station can rapidly configure the SCell or the PSCell for the UE, and when the UE is in an idle state or an inactive state, the base station configures N frequency points where the potential SCell or the PSCell is located for the UE, so that the UE can measure the N frequency points in advance.

Because the resource of the UE for performing the frequency point measurement is limited, and the total number of the frequency points to be measured may be increased by performing the measurement in advance, it is necessary to determine whether the measurement in advance affects the reselection measurement before performing the measurement in advance, thereby affecting the mobility. The base station configures an RSRP or RSRQ threshold of a serving cell for the UE, and when the value of the RSRP or RSRQ of the serving cell is smaller than a set threshold, the base station enters a relaxation mode of advanced measurement, so that the influence of the advanced measurement on reselection measurement is reduced.

For reselection measurements, the following are specified in the standard: when the channel condition of the serving cell is better (RSRP or RSRQ is higher than SnonIntraSearch), the UE only measures the pilot frequency point with high priority; when the channel condition of the serving cell is poor (RSRP or RSRQ is lower than SnonIntraSearch), the UE measures all configured pilot frequency points.

In one possible embodiment, the threshold for entering the early measurement relaxation mode is determined to be a threshold for inter-frequency reselection measurement (snonIntraSearch). In another possible embodiment, the threshold for entering the early measurement relaxation mode is determined to be a threshold for inter-frequency reselection measurement that is not too high.

Step S105, when the value of the RSRP or the RSRQ of the service cell is smaller than a set threshold value, the measurement behavior of each frequency point in the N frequency points measured in advance is determined.

After the UE receives the RSRP or RSRQ threshold value of the serving cell for controlling the early measurement relaxation mode, the RSRP or RSRQ value of the current serving cell where the UE is located is obtained, and then whether the RSRP or RSRQ value of the current serving cell is larger than the RSRP or RSRQ threshold value received from the base station or not is judged.

If the RSRP or RSRQ value of the current serving cell is greater than the RSRP or RSRQ threshold value received from the base station, it indicates that the channel condition of the serving cell where the UE is currently located is better, and the UE can normally perform advance measurement on the frequency point where the potential SCell or PSCell is located.

If the value of the RSRP or the RSRQ of the frequency point where the current serving cell is located is smaller than the threshold value of the RSRP or the RSRQ received from the base station, it indicates that the channel condition of the serving cell where the UE is located is poor, and therefore the number of target frequency points which the UE may reselect to measure is large. At this time, due to the resource of the UE for performing the frequency point measurement, if the UE still performs the advanced measurement on the frequency point where the potential SCell or PSCell is located, the UE needs to perform the relaxation processing on the frequency point where the potential SCell or PSCell is located, so that the influence on the reselection measurement is minimized while the advanced measurement is performed on the frequency point where the potential SCell or PSCell is located.

Generally, the measurement behavior of the UE on the advanced frequency point includes normal measurement, relaxation measurement and no periodic measurement. The normal measurement is that the UE carries out periodic measurement on the frequency point according to the set requirement; the relaxation measurement is that the UE relaxes and sets a requirement for periodic measurement on the frequency point, for example, the time interval for periodic measurement on the frequency point is prolonged; the non-periodic measurement is one-time measurement or non-measurement of the frequency point.

In the embodiment of the present application, the UE sets a relaxation mode for measurement in advance, that is, a part of frequency points in frequency points where a potential SCell or PSCell is located are measured with a normal measurement behavior, a part of frequency points are measured with a relaxation measurement behavior, and another part of frequency points are measured with a measurement behavior that is not measured periodically. When the UE performs reselection measurement, a relaxation mode of advanced measurement is entered to perform advanced measurement on all or part of frequency points where the potential SCell or PSCell is located.

In the embodiment of the present application, the measurement behavior manner for determining each frequency point (frequency point measured in advance) where a potential SCell or PSCell is located to perform measurement is as follows:

1. the UE directly sets M frequency points measured in advance to carry out normal measurement, R frequency points measured in advance carry out relaxation measurement, and S frequency points measured in advance do not carry out periodic measurement. The minimum value of M, R and S is 0, and the maximum value can be determined according to factors such as predefinition in international standards, base station configuration, or the number of frequency points for reselection measurement.

Illustratively, the UE performs relaxation measurement on a maximum of 3 frequency points measured in advance, and does not perform periodic measurement on other frequency points measured in advance, so that Mmax is 0 and Rmax is 3.

Exemplarily, when the number of frequency points for reselection measurement is less than or equal to 3, the UE performs normal measurement on at most 2 frequency points measured in advance, and performs relaxation measurement on other frequency points measured in advance, where Mmax is 2 and Rmax is N-1; when the frequency point number of reselection measurement is greater than 3, the UE performs relaxation measurement on at most 3 frequency points measured in advance, and other frequency points measured in advance do not perform periodic measurement, so that Mmax is 0, and Rmax is 3.

2. The UE divides the frequency points measured in advance into a plurality of types according to the types of the frequency points measured in advance, then the frequency points measured in advance of the first type are subjected to normal measurement, the frequency points measured in advance of the second type are subjected to relaxation measurement, and the frequency points measured in advance of the third type are not subjected to periodic measurement.

If the frequency points measured in advance are less than three types, the frequency points measured in advance can be measured by one of normal measurement, relaxation measurement or periodic measurement; if the frequency points measured in advance exceed three types, the frequency points measured in advance of several types can be measured by the same measuring action.

Illustratively, the UE specifies different types of frequency points measured in advance to have different priorities according to the types of the frequency points measured in advance, so that the frequency point measured in advance with a high priority is subjected to normal measurement, the frequency point measured in advance with a second highest priority is subjected to relaxation measurement, and the frequency point measured in advance with a low priority is not subjected to periodic measurement. The priority mode of the frequency points which are specified to be measured in advance comprises the following steps:

(1) the frequency point of the cross-system is more than the frequency point of the cross-Frequency Range (FR) is more than the frequency point of the cross-frequency band (band);

(2) the frequency point where the potential PSCell is located is greater than the frequency point where the potential SCell is located;

(3) and the base station specifies the priority of the frequency points measured in advance.

For example, the UE determines that all the across-system frequency points perform normal measurement, all the across-frequency points perform relaxed measurement, and other frequency points do not perform periodic measurement.

3. The UE may determine, according to the specified number and priority, a measurement behavior for performing measurement on each frequency point measured in advance.

Illustratively, the UE specifies the first M frequency points with high priority to be measured in advance for normal measurement, the first R frequency points with high priority to be measured in advance except the frequency points with normal measurement to be measured in advance for relaxation measurement, and the first S frequency points with high priority to be measured in advance except the frequency points with normal measurement and relaxation measurement to be measured for non-periodic measurement.

And S107, measuring each frequency point measured in advance according to the measuring behavior corresponding to each frequency point measured in advance.

After the UE enters a relaxation mode of measurement in advance, after the measurement behavior corresponding to each frequency point in the frequency points measured in advance is determined, the corresponding measurement behavior is adopted for each frequency point measured in advance to carry out measurement.

Illustratively, if it is determined that the measurement behavior of the frequency point measured in advance is measured normally, the measurement time requires a relaxation factor N1, and N1 is:

k is a relaxation factor, and the value of K can be determined according to the relationship of frequency point number and the like predefined in international standards or configured by a base station or measured by reselection; m is the number of the frequency points measured in advance for normal measurement, and L is the number of reselection measurement.

Illustratively, if the measurement behavior of the frequency point measured in advance is relaxation measurement, the measurement time requires a relaxation factor of N2, N2 is:

N2＝K·R

wherein K is a relaxation factor, and R is the number of frequency points measured in advance for relaxation measurement.

Illustratively, if the measurement behavior of the frequency point measured in advance is determined not to be periodic measurement, the frequency point makes one-time measurement or has no measurement requirement.

In the embodiment of the present application, in order to ensure the performance of reselection measurement, it is necessary to relax the advance measurement, that is, enter a relaxation mode of advance measurement.

By defining the frequency point priorities of a plurality of frequency points measured in advance, and the number of the frequency points passing through the same measurement behavior, UE can select different measurement behaviors for different frequency points according to the measurement capability and the priority sequence of the frequency points, so that different measurement performances are achieved, and the high-priority frequency points are ensured to finish measurement quickly. Since the high-priority frequency point corresponds to the PSCell or SCell that the UE is more likely to add, the UE is more likely to be added with CA and DC quickly when entering a connected state.

Meanwhile, when the UE enters the early measurement relaxation mode, an intermediate scheme is introduced between normal measurement and no periodic measurement, namely the periodic measurement is carried out at K times of measurement intervals, so that the influence on the reselection measurement is reduced to the minimum, and the early measurement is ensured to a certain extent.

In addition, the UE does not enter a relaxation mode of advanced measurement within an idle state, an inactive state or a period of time after finishing reselection measurement; or after the UE enters idle state, inactive state or completes reselection measurement, restarting the T331 timer, and before the T331 timer expires, not entering a relaxation mode of advanced measurement. After the UE reselects, the potential PSCell and SCell may change due to the change of the serving cell, and at this time, the measurement results of the potential PSCell and SCell are quickly obtained, so that it can be ensured that the UE can quickly establish CA and DC when entering a connected state soon after reselection.

The frequency point configured for advance measurement by the base station may be the same as or different from the frequency point reselected and measured by the UE, so that the frequency point configured for advance measurement may be divided into an overlapping frequency point (overlapping carrier) and a non-overlapping frequency point (non-

overlapping carrier). Wherein, the overlapping carrier indicates that the frequency point measured in advance is also the frequency point of reselection measurement being measured by the UE; the non-overlapping carrier indicates that the frequency point measured in advance is not the frequency point of reselection measurement being measured by the UE. In the above embodiment, the "frequency point measured in advance" may refer to both overlapping carrier and non-overlapping carrier, and may also refer to non-overlapping carrier, which is not limited herein.

If the UE determines that it is in the power saving mode in step S101, the UE further needs to perform the following steps when the UE is in idle or inactive state in the power saving mode:

step S109, when determining to be in the power saving mode, receiving second parameter information configured by the base station.

When the UE is in the power saving mode, the UE may reduce reselection measurement to achieve the purpose of saving power, and in order to enable the UE to determine whether the UE can enter a relaxation mode of reselection measurement, the base station may configure a threshold parameter for the UE to determine whether the UE is in one or both of a low mobility state and a cell edge state.

And step S111, determining the measurement behavior of each frequency point in the N frequency points measured in advance according to the second parameter information, and measuring.

The following explains, according to table one, a specific manner in which the UE determines the measurement behavior for each frequency point measured in advance in the power saving mode is as follows:

TABLE 1 UE DETERMINATION OF MEASUREMENT BEHAVIOR IN N PRE-MEASUREMENT FREQUENCY POINTS IN DIFFERENT STATES

In the first case, when the UE is not in low mobility and not in a cell edge state, the UE may or may not need to perform reselection measurements. However, for the advanced measurement, if the UE performs reselection measurement, all the frequency points measured in advance (including the frequency points measured in advance by overlapping and the frequency points measured in advance by non-overlapping) perform the same measurement behavior as the reselection measurement. If the UE does not perform reselection measurement, all the frequency points measured in advance are measured according to the measurement behaviors of the relaxation mode of measurement in advance described in steps S101 to S107 in fig. 1 and the corresponding embodiments.

In the second case, when the UE is in low mobility but not in cell edge state, the UE does not need to make reselection measurements at this time. However, for the advance measurement, all the frequency points measured in advance are measured according to the measurement behavior of the relaxation mode of the advance measurement described in steps S101 to S107 in fig. 1 and the corresponding embodiment.

In a third case, when the UE is not in low mobility but in a cell edge state, the UE performs normal measurements for reselection measurements at this time. At this time, the overlapping carrier and the non-overlapping carrier need to be discussed separately. Measuring the frequency points measured in advance by overlapping by the same measuring behavior as the reselection measurement; the non-overlapping measured frequency points in advance are measured according to the measurement behavior of the relaxation mode of the measurement in advance described in steps S101-S107 in fig. 1 and the corresponding embodiments.

In the fourth case, when the UE is in low mobility and in a cell edge state, the UE may or may not need to perform reselection measurements. However, for the advanced measurement, if the UE performs reselection measurement, all the frequency points measured in advance (including the frequency points measured in advance by overlapping and the frequency points measured in advance by non-overlapping) perform the same measurement behavior as the reselection measurement. Wherein the measurement behavior of the reselection measurement is either a normal measurement or a relaxed measurement. If the UE does not perform reselection measurement, all the frequency points measured in advance are measured according to the measurement behaviors of the relaxation mode of measurement in advance described in steps S101 to S107 in fig. 1 and the corresponding embodiments.

In the embodiment of the application, when the UE is in a node mode and in a low mobility state, the potential PSCell and SCell of the UE generally do not change, and in this case, releasing the advance measurement can achieve power saving without affecting the rapid establishment of CA and DC.

Fig. 2 is a flowchart of a control method according to an embodiment of the present application. As shown in fig. 2, the method is executed by the base station, and specifically includes the following steps:

step S203, sending first configuration information and a set threshold value of Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ) of the communication device entering a relaxation mode measured in advance to the communication device.

When the UE is in idle or inactive state, the base station can rapidly configure the SCell or the PSCell for the UE when the UE is in connected state, and configure N frequency points where the potential SCell or PSCell is located for the UE, so that the UE can measure the N frequency points in advance.

Meanwhile, the base station needs to configure, for the UE, an RSRP or RSRQ threshold of a frequency point where a serving cell for determining whether the UE performs reselection measurement is located.

Step S205, sending the second configuration information to the communication device.

In order to control the UE to enter the measurement behavior of each frequency point measured in advance in the advance measurement relaxation mode, optionally, the base station loosens second configuration information to the UE, where the second configuration information has control parameters for controlling each frequency point measured in advance in the N frequency points measured in advance to perform the measurement behavior. Namely, a part of frequency points of the frequency points where the potential SCell or PSCell is located are measured by normal measurement behaviors, a part of frequency points are measured by relaxation measurement behaviors, and other parts of frequency points are measured by measurement behaviors without periodic measurement.

The measurement behavior mode for determining each frequency point (frequency point measured in advance) where the potential SCell or PSCell is located to measure is as follows:

1. the UE directly sets M frequency points measured in advance to carry out normal measurement, R frequency points measured in advance carry out relaxation measurement, and S frequency points measured in advance do not carry out periodic measurement. The minimum value of M, R and S is 0, and the maximum value may be determined according to factors such as predefinition in international standards, configuration of the base station through the second configuration information, or the number of frequency points for performing reselection measurement.

It should be noted that the making of the relaxation mode of the advance measurement and the determining of the measurement behavior of the frequency points of the advance measurement may be completed by the UE side, or may be completed by the base station side, which is not limited herein.

Before configuring the measurement frequency point for the UE in advance, the base station also needs to determine whether the UE is in the power saving mode for judgment, so that the following steps need to be executed:

step S201, sending the third configuration information to the communication device.

The first parameter information is for the UE to determine whether the UE is in the node mode. When the UE receives the first parameter information, it determines whether it is in the power saving mode, and if it is in the node mode, step S203 is executed again.

Step S207, when determining that the communication device is in the power saving mode, transmitting fourth configuration information to the communication device.

When a base station configures UE to start a power saving mode, the UE can achieve the purpose of saving power by reducing reselection measurement, and in order to enable the UE to judge whether the UE can enter a relaxation mode of reselection measurement, the base station configures a threshold parameter for the UE to judge whether the UE is in one or two states of low mobility and cell edge.

Wherein, the relaxation factor required by the measurement time of the frequency point measured in advance in normal measurement is N1, and N1 is:

The relaxation factor required by the measurement time of the frequency point measured in advance for relaxation measurement is N2, and N2 is:

N2＝K·R

Step S209, receiving fifth configuration information sent by the communication device.

After the UE side determines the measurement behavior corresponding to each frequency point measured in advance, the base station needs to be sent so that the base station determines the measurement behavior of each frequency point where the SCell or PSCell is potentially configured for the UE.

In the first case, when the UE is not in low mobility and is not in a cell edge state, the UE may need to perform reselection measurement or may not perform reselection measurement. However, for the advanced measurement, if the UE performs reselection measurement, all the frequency points measured in advance (including the frequency points measured in advance by overlapping and the frequency points measured in advance by non-overlapping) perform the same measurement behavior as the reselection measurement. If the UE does not perform reselection measurement, all the frequency points measured in advance are measured according to the measurement behaviors of the relaxation mode of measurement in advance described in steps S101 to S107 in fig. 1 and the corresponding embodiments.

In the embodiment of the application, the base station configures the frequency point measured in advance for the UE and the set threshold of the RSRP or the RSRQ entering the relaxation mode of measurement in advance, so that the UE can measure the frequency point measured in advance without influencing reselection measurement according to the set threshold. Meanwhile, the UE is configured with parameter information for starting the power saving mode and judging whether the communication equipment is in a low mobility state and/or a cell edge state, so that the advanced measurement in the power saving mode is realized.
