Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for estimating a mobility state, a method for sending a parameter, a terminal, and a network device.
Background
When the existing mobile terminal reselects or passes through a cell, the mobile state estimation method comprises the following steps: the terminal counts the number of reselected cells in a certain time and judges that the moving state of the terminal is high speed, medium speed and low speed.
The disadvantages of this mobility state estimation method are:
1) the speed estimation error is caused by different reselections of the UE (User Equipment or terminal) or different routes passing through the cell. The UE may only pass through the cell edge, or the cell edge may reselect completely from the cell center to the cell edge, or pass through the entire cell. Existing solutions do not distinguish between these two routes, both consider reselecting or crossing 1 cell; resulting in a speed estimation error of the UE.
2) In the high frequency band, the base station no longer transmits in the form of cell sectors, but transmits in the form of narrow beams, as shown in fig. 1, there may be 8 beams in a cell, and of course there may be 32 beams. The statistics of the number of cells for different beams, such as terminal reselection or sector beams passing through a high frequency band and cell numbers passing through a narrow beam, are the same, so that the estimation error of the mobile speed is large.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The embodiment of the invention provides a method for estimating the mobile state of a terminal aiming at the problem that the mobile state estimation of the terminal is inaccurate in the prior art, and considers the situation of beams passed by a mobile track while considering the mobile track, so that the mobile state of the mobile terminal can be estimated more accurately.
As shown in fig. 2, an embodiment of the present invention provides a method for estimating a mobility state of a terminal, where the method includes:
and step 23, estimating the moving state of the terminal according to the equivalent cell number and the first threshold.
For example, if the motion state decision threshold includes only one motion state decision threshold, such as the first motion state decision threshold; in this step, the method may specifically include:
if the number of the equivalent cells is greater than the first moving state decision threshold, estimating that the moving state of the terminal is a state moving at a first moving speed, otherwise estimating that the moving state of the terminal is a state moving at a second moving speed, wherein the first moving speed is greater than the second moving speed, for example, the first moving speed may be a high-speed state, and the second moving speed is a low-speed state; and vice versa.
If the moving state decision threshold comprises: when the second moving state decision threshold is greater than the third moving state decision threshold, if the number of the equivalent cells exceeds the second moving state decision threshold, estimating the moving state of the terminal to be a state moving at a third moving speed;
if the equivalent cell number exceeds a third moving state judgment threshold and does not exceed a second moving state judgment threshold, estimating the moving state of the terminal to be a state moving at a fourth moving speed;
and if the equivalent cell number does not exceed the third moving state judgment threshold, estimating the moving state of the terminal to be a state moving at a fifth moving speed.
Wherein the third moving speed is greater than the fourth moving speed, and the fourth moving speed is greater than the fifth moving speed. That is, at this time, it can be determined that the third moving speed is in the high speed state, the fourth moving speed is in the medium speed state, and the fifth moving speed is in the low speed state.
Of course, in the embodiment of the present invention, the first threshold may further include 3 or more motion state decision thresholds, and the more the motion state decision thresholds are, the higher the accuracy of estimating the motion state is for the terminal.
In the above embodiment of the present invention, step 22 may specifically include:
step 221, receiving a second threshold and at least one weight value sent by the network device;
the second threshold here includes at least one moving trajectory decision threshold, and in general, the moving trajectory of the terminal when reselecting or passing through a cell can be roughly divided into two types no matter the cell of several beams:
the first is to traverse the beam, i.e. the terminal follows the shortest path, perpendicular to the beam radius, as shown in figure 3.
The second is a longitudinal beam, as shown in fig. 4, where the terminal follows the longest path, along the beam radius.
Of course, it is also possible to slant through the beam as shown in fig. 5.
When the beam is fan-shaped or circular, as shown in fig. 6, the trajectory of the terminal's reselection or movement through the cell may include various paths traversing the beam.
In fig. 3 to fig. 6, each trajectory passing through a beam needs to use the moving trajectory decision threshold to determine that the weight is determined by the network device according to the number of beams included in a cell; the width of the beam may vary in different frequency bands. For example, in the middle frequency band, a base station may need to cover a region with 8 beams. Whereas in the high frequency band it is necessary to cover a field with 32 beams. The beams of the 8-beam cell are slightly wider and the beams of the 32-beam cell are slightly narrower. The weight of each beam will be different. When a cell includes 8 beams, the equivalent cell number of each beam is 1/8 cells (1 in 8), i.e. each time the UE crosses one beam in an 8-beam cell, it is recorded as 1/8, and it crosses two as 2/8. When a cell includes 32 beams, the equivalent cell number of each beam is 1/32 cells, i.e. each time the UE crosses one beam in a 32-beam cell, it is recorded as 1/32, and the crossing of two is recorded as 2/32.
Here, when the "weight" of each beam is a numerical value obtained according to the number of beams included in one cell, the specific value may be the reciprocal of the number of beams included in one cell.
Step 221, obtaining the number of equivalent cells reselected or passed by the terminal within a preset time period according to the second threshold and the at least one weight.
Specifically, the step 221 may include:
step 2211, obtaining the measured value of the terminal in the cell or the beam;
step 2212, determining a weight corresponding to the movement track of the terminal in the cell or the beam according to the measurement value and the second threshold;
and 2213, obtaining the equivalent cell number reselected or passed by the terminal in a preset time period according to the weight value corresponding to the movement track of the terminal in the cell or the wave beam.
For example, if the weight value adopted when traversing the beam is 1/8 cells, the number of equivalent cells traversed by the terminal within a preset time period is: and counting the number of equivalent cells which are crossed according to the distance of each beam occupying 1/8 cells.
In this embodiment, the measured values may be: a first measurement value obtained from Reference Signal ReceivingPower (Reference Signal received power) of a serving cell; or, a second measurement value obtained according to the RSRQ (reference signal Receiving Quality) of the serving cell; or, a third measurement value obtained from a SINR (Signal to Interference plus Noise Ratio) of the serving cell; or a fourth measurement value obtained from Srxlev (cell selection reception level value) of the serving cell.
Wherein the first measurement value is a difference between a maximum value and a minimum value of the RSRP or a maximum value of the RSRP; the second measurement value is a difference value between a maximum value and a minimum value of the RSRQ or a maximum value of the RSRQ; the third measurement value is the difference value between the maximum value and the minimum value of the SINR or the maximum value of the SINR; the fourth measurement is a difference between a maximum value and a minimum value of the Srxlev or a maximum value of the Srxlev.
In this embodiment, the moving track decision threshold may be multiple moving track decision thresholds, and when the moving track decision threshold includes only: when the first movement track decision threshold is reached, the movement track of the terminal in the cell or the beam includes: a first movement trajectory when the measured value is greater than the first movement trajectory decision threshold, or a second movement trajectory when the measured value is less than or equal to the first movement trajectory decision threshold. The first movement track is a movement track crossing a cell or a beam; the second moving track is a moving track of a vertical cell or a beam. And vice versa.
When the moving track judgment threshold comprises the following steps: a first moving track judgment threshold and a second moving track judgment threshold, and when the first moving track judgment threshold is larger than the second moving track judgment threshold
The moving track of the terminal in the cell or the beam comprises: a third movement trajectory when the measured value is greater than a second movement trajectory decision threshold; or a fourth movement track when the measured value is greater than a third movement track judgment threshold and less than the second movement track judgment threshold; or a fifth movement trajectory when the measured value is less than the fourth movement trajectory decision threshold. The third movement track is a movement track crossing a cell or a beam; the fourth moving track is a moving track of a vertical cell or a beam; the fifth moving track is a moving track of a cross cell or a beam. Of course, when the beam is circular or fan-shaped, the weight of each beam is 1.
In the embodiment of the present invention, the moving track decision threshold may further include 3 or more moving track decision thresholds, and the more the moving track decision thresholds are, the more the types of beams passed by the terminal are determined, and the more accurate the estimation of the moving state is.
The following describes a specific implementation process of the above embodiment with reference to fig. 3 to 6:
in fig. 3 is the movement trajectory across the beam, i.e. the terminal follows the shortest path, perpendicular to the beam radius.
Fig. 4 is a trajectory of movement of a traversing beam, i.e., the terminal traverses along the longest path, along the beam radius.
Fig. 5 illustrates a moving trajectory of the slant-through beam.
The network device needs to broadcast three parameters, namely a weight of a transverse beam, a weight of a longitudinal beam, a weight of an oblique beam, and a moving track judgment threshold for judging whether the terminal is transverse beam, longitudinal beam or oblique beam.
The threshold can be RSRP, RSRQ, SINR, or Srxlev. Taking the RSRP threshold as an example, the terminal obtains a first measurement value according to a difference between a maximum RSRP and a minimum RSRP of a serving cell measured on a current SSB (Synchronization Signal Block) of a current cell, which may be the maximum RSRP at this time, where the minimum RSRP is 0.
Comparing the first measured value with a moving track judgment threshold, and if the first measured value is greater than the moving track judgment threshold, adopting the weight crossing the beam as the count of the cell or the SSB ID or the beam; and if the first measurement value is smaller than the moving track judgment threshold, adopting the weight of the longitudinal beam as the count of the cell or the SSB ID or the beam.
If for higher accuracy the threshold and weight can be increased. If two thresholds and three weights are used, the transverse, oblique and longitudinal beams of the terminal can be judged.
Such as: if the difference between the maximum value and the minimum value of the RSRP is larger than a first movement track judgment threshold, using the weight value of the crossed beam as the count of the cell or the SSB ID or the beam;
if the difference between the maximum value and the minimum value of the RSRP is larger than the second movement track judgment threshold and smaller than the first movement track judgment threshold, using the weight of the longitudinal beam as the count of the local cell or the local SSB ID or the local beam;
and if the difference between the maximum value and the minimum value of the RSRP is smaller than a second movement track judgment threshold, using the weight of the obliquely-penetrated beam as the count of the cell or the SSB ID or the beam.
As shown in fig. 6, for a low-frequency sector or circular cell (non-beam), it may also be determined whether to cross the cell or to cut the edge of the cell by comparing the difference between the maximum value and the minimum value of RSRP received by the UE in the cell with the movement trajectory decision threshold. And different weights are set for different cell-through methods.
For example, the network broadcasts the following parameters: the first weight, the second weight, the third weight, the first moving track decision threshold and the second moving track decision threshold; here, the first weight corresponds to the weight of path 1, the second weight corresponds to the weight of path 2, and the third weight corresponds to the weight of path 3:
if the difference between the maximum value and the minimum value of the RSRP is larger than a first movement track judgment threshold, using a first weight as the count of the cell or the SSB ID or the beam;
if the difference between the maximum value and the minimum value of the RSRP is larger than the second movement track judgment threshold and smaller than the first movement track judgment threshold, using a second weight as the count of the local cell or the local SSB ID or the local beam;
and if the difference between the maximum value and the minimum value of the RSRP is smaller than a second movement track judgment threshold, using the third weight as the count of the cell or the SSB ID or the beam.
In the embodiments of the present invention, the determination threshold of the moving trajectory and the corresponding weight are not limited. The more the judgment threshold of the moving track is, the more the type of the wave beam which is passed by the terminal is determined, and the more accurate the estimation is; the more the motion state decision threshold, the more accurate the estimation is.
In the above embodiments of the present invention, the first, second, and nth are not used to indicate the related order, but are merely used for illustration and are not used to limit the protection scope of the present invention. The scheme of the embodiment of the invention can be applied to a multi-beam scene, and the terminal moving state can be judged with higher precision by considering the terminal moving track.
