Detailed Description
Before describing the embodiments of the present application, the terms referred to in the embodiments of the present application are explained:
RRM measurement: RRM measurement refers to measurement of the current serving cell and the current serving cell by the terminal device. The terminal device may perform handover, selection, or reselection of the cell through RRM measurement.
In a fifth generation (5 th) network, the terminal device may perform downlink measurement on different signals in order to perform RRM measurement. In idle mode, the UE may measure the cell using a cell-specific SSB (synchronization signal block) to obtain the quality of the cell. In the connected mode, the UE may use a channel state information-reference signals (CSI-RS) dedicated to the UE in addition to the SSB for mobility measurement. When the terminal equipment carries out measurement in the same-frequency connection mode, at most 2 measurement window periods can be configured, so that the terminal equipment can conveniently measure different cells.
When performing RRM measurement on a cell, a terminal device typically performs RRM measurement according to a measurement requirement specified by an air interface protocol, and a time period of the RRM measurement is fixed. That is, the terminal device may perform the RRM cycle at a fixed time period. Alternatively, it can also be described that the time interval of two adjacent RRM measurements of the terminal device is fixed.
But in some scenarios, for example, the location of the terminal device changes little, or the terminal device is located at the cell center point. When the terminal device is in a small position change or is located at the center point of the cell, the communication environment of the terminal device is stable. In this case, the terminal device generally does not need to perform RRM measurement, and if the terminal device still performs RRM measurement, power consumption of the terminal device increases.
In order to solve the problem, an embodiment of the present application provides a measurement method, including: the method comprises the steps that network equipment obtains a plurality of signal quality parameters of a first measurement period of terminal equipment and a plurality of signal quality parameters of a current measurement period, wherein the first measurement period is a measurement period before the current measurement period; the network equipment determines the moving speed and the position information of the terminal equipment in the current measurement period; and the network equipment determines the time length of the measurement period after the current measurement period of the terminal equipment according to the plurality of signal quality parameters of the first measurement period, the plurality of signal quality parameters of the current measurement period, the position information of the terminal equipment and the moving speed.
In the method provided by the embodiment of the application, the network device may determine a change condition between the terminal device and the network device based on a plurality of signal quality parameters of the terminal device in a current measurement period and a plurality of signal quality parameters before the current measurement period. Based on the moving speed and the position information of the current measurement period of the terminal equipment and the change condition of the communication network, the network equipment can determine whether to adjust the time length of the measurement period after the current measurement period, and the method is accurate and comprehensive.

Fig. 3 provides a measurement method for an embodiment of the present application, and as shown in fig. 3, the method includes:
step 301, the network device obtains a plurality of first signal quality parameters and a plurality of second signal quality parameters of the terminal device.
The network device may be any one of the network devices in fig. 1, such as network device 110 or network device 120. The terminal device may be the terminal device in fig. 1, such as terminal device 130.
The first signal quality parameter is a signal quality parameter of the terminal device in a first measurement period. The second signal quality parameter is the signal quality parameter of the terminal device in the current measurement period. The first measurement period is a measurement period before the current period. The signal quality parameter may be used to characterize the quality of communication between the terminal device and the network device. For example, the signal quality parameter may include at least one of a Reference Signal Receiving Power (RSRP), a signal to interference plus noise ratio (SINR), a Reference Signal Receiving Quality (RSRQ), a Received Signal Strength Indication (RSSI).
The plurality of first signal quality parameters may refer to a plurality of signal quality parameters acquired by the terminal device at time intervals in the first measurement period, or may be a plurality of signal quality parameters randomly acquired by the terminal device in the first measurement period, which is not limited.
In one possible implementation, the network device may obtain a plurality of first signal quality parameters of the terminal device from a Measurement Report (MR) of the terminal device.
Further, in order to more accurately determine the change condition of the communication quality between the network device and the terminal device, the network device may obtain signal quality parameters of a plurality of measurement periods before the current measurement period, that is, the network device may obtain a plurality of signal quality parameters of each measurement period in the plurality of measurement periods. The plurality of measurement cycles are consecutive measurement cycles before the current measurement cycle, or may be a plurality of measurement cycles within a preset time period before the current measurement cycle, which is not limited.
Step 302, the network device determines the moving speed and the position information of the terminal device in the current measurement period.
The moving speed of the terminal device in the current measurement period may refer to location change information of the terminal device in the current measurement period. The location change information may include a plurality of coordinate information and corresponding times. The coordinate information may be latitude and longitude information. The network device may calculate the moving speed of the terminal device according to the plurality of pieces of coordinate information and the corresponding time.
The location information of the terminal device in the current measurement period may refer to coordinate information of the terminal device in the current measurement period. The location information of the terminal device in the current measurement period may be determined based on a plurality of second signal quality parameters. For example, the network device may determine the location information of the terminal device according to a difference between an average value of the plurality of second signal quality parameters and a signal quality parameter at an edge of a coverage area of the network device.
In one example, the network device may be preconfigured with signal quality parameters for the edge of the coverage area. The network device may calculate a difference between the average of the plurality of second signal qualities and a signal quality parameter at the edge of the coverage area. If the difference is greater than the preset difference, it indicates that the terminal device is located within the preset range, or the distance between the terminal device and the network device is less than the preset distance. And under the condition that the terminal equipment is positioned in the preset range or the distance between the terminal equipment and the network equipment is less than the preset distance, the signal quality of the position where the terminal equipment is positioned is better or the network environment is stable. The preset range and the preset distance can be set according to needs and are not limited.
Step 303, the network device determines the time length of the terminal device in the second measurement period according to the plurality of first signal quality parameters, the plurality of second signal quality parameters, the moving speed of the terminal device, and the location information.
And the second measurement period is a measurement period after the current measurement period. The time length of the second measurement period may refer to a time length of the RRM measurement of the terminal device in the second measurement period, or may refer to a time interval between the RRM measurement of the second measurement period and the RRM measurement of the current measurement period.
In a possible implementation manner, if the change index of the communication network between the terminal device and the network device is smaller than the preset value and the moving speed of the terminal device is smaller than the preset speed, and/or the terminal device is located in the preset area, the network device determines the time length of the second measurement period according to the adjustment coefficient and the current measurement period.
The preset value and the preset speed can be set according to needs and are not limited.
Wherein, the change index of the communication network can be used for representing the change condition of the communication network. For example, the change index of the communication network may be determined based on a plurality of first signal quality parameters of a first measurement period and a plurality of second signal quality parameters of a current measurement period.
In one example, the change index of the communication network may be an absolute value of a difference between a mean value of the plurality of first signal quality parameters and a mean value of the plurality of second signal quality parameters.
For example,
. Wherein the content of the first and second substances,
in order to be an index of change of the communication network,
is the average of a plurality of first signal quality parameters,
is the mean of a plurality of second signal quality parameters.
In yet another example, the change index of the communication network may be an absolute value of a difference between a mean value of the plurality of first signal quality parameters and a mean value of a maximum value and a minimum value of the plurality of second signal quality parameters.
For example,
. Wherein the content of the first and second substances,
in order to be an index of change of the communication network,
is the average of a plurality of first signal quality parameters,
is the maximum of the plurality of second signal quality parameters,
is the minimum of the plurality of second signal quality parameters.
The terminal device is located in the preset area may mean that a distance between the terminal device and the network device is smaller than a preset distance. When the terminal device is located in the preset area, the communication quality between the terminal device and the network device is relatively stable. The more stable the communication quality of the terminal device and the network device, the more uniform the result of the plurality of RRM measurements by the terminal device is, which means that in this case the RRM measurement period of the terminal device may need to be adjusted. For example, the RRM measurement period of the terminal device is extended to reduce the power consumption of the terminal device.
It should be noted that the change index of the communication network is smaller than the preset value and the moving speed of the terminal device is smaller than the preset speed, and/or the terminal device located in the preset area may include the following three cases:
in case 1, the change index of the communication network is smaller than the preset value, and the terminal device is located in the preset area.
And 2, the change index of the communication network is smaller than a preset value, and the moving speed of the terminal equipment is smaller than a preset speed.
And 3, the change index of the communication network is smaller than the preset value, the terminal equipment is located in the preset area, and the moving speed of the terminal equipment is smaller than the preset speed.
That is, when any of the above three conditions is satisfied, the network device needs to determine the time length of the second measurement period according to the adjustment coefficient and the current measurement period. For example, the time length of the second measurement period may be a product of the adjustment coefficient and the time length of the current measurement period.
Wherein the adjustment factor may be determined according to a plurality of second signal quality parameters. The plurality of second signals may include at least one first parameter and at least one second parameter, the first parameter and the second parameter being different signal quality parameters of the plurality of second signal quality parameters. The adjustment factor may be determined based on the indication of a first parameter and the at least one second parameter. For example, the adjustment coefficient may be determined according to equation one.
Wherein the content of the first and second substances,
in order to adjust the coefficients of the coefficients,
and
is a predetermined coefficient and
，
is determined on the basis of at least one first parameter,
based on at least one second parameterAnd ⌈ ⌉ denotes rounding up.
For example, in the case of a liquid,
∆1，
Δ 2. Wherein the content of the first and second substances,
is the mean value of the at least one first parameter,
is the variance of the at least one first parameter.
Is the mean value of the at least one second parameter,
is the variance of the at least one second parameter. The values of Δ 1 and Δ 2 are greater than 0, and the values of Δ 1 and Δ 2 may be set as desired. The size of either or both of Tan 1 and Tan 2 may be the same or not.
In a further aspect of the present invention,
and
or may be determined based on a plurality of second signal quality parameters. For example,
，
。
for example, the first parameter is RSRP, and the second parameter is SINR. Then
。
. The coefficients in the two formulas can refer to the above description, and are not repeated.
The adjustment coefficient M is calculated in combination with specific values.
Take the example that the second signal quality parameter of the terminal device comprises RSRP and SINR.
For example, the RSRP values of the terminal device in the first measurement period are respectively: 89 decibel millimeter (dbm), -90dbm, -86dbm, -94 dbm, -96 dbm, -87 dbm, -86dbm, -81dbm, -97 dbm, -94 dbm. The SINR values are: 14db, 17db, 24db, 19db, 18db, 21db, 18db, 22db, 23 db. Then
=-90dbm，
=20db。
For another example, the RSRP values of the terminal device in the current measurement period are respectively: -85dbm, -92dbm, -84dbm, -90dbm, -95 dbm, -86dbm, -90dbm, -80dbm, -95 dbm, -90 dbm. The SINR values are: 16db, 20db, 18db, 22db, 21db, 15db, 16db, 19db, 23db, 20 db. Then
=-88.7dbm，
=22.4。
=19db，
=6.6。
From the above-mentioned values, it can be obtained,
=0.3, or,
= 7.5. Or =1, or,
=1。
if the threshold corresponding to the change index is 0.1, and the terminal device is located in the preset area and/or the moving speed of the terminal device is less than the preset speed, the adjustment coefficient determined by the network device is as follows:
for example, Δ 1=5, Δ 2=4
=
∆1=22.22，
Δ 2= 3.1. Alternatively, the first and second electrodes may be,
=3.1，
22.22。
to be provided with
