Detailed ways

In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the following briefly introduces the accompanying drawings that need to be used in the embodiments of the present invention. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can also be obtained from these drawings without any creative effort.

The term "and/or" in this article is only an association relationship to describe the associated objects, indicating that there can be three kinds of relationships, for example, A and/or B, it can mean that A exists alone, A and B exist at the same time, and A and B exist independently B these three cases.

The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific order of the objects. For example, the first specific time, the second specific time, etc. are used to distinguish different specific times, and are not used to describe a specific order of the specific times.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as an example, illustration or illustration. Any embodiments or designs described as "exemplary" or "such as" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "plurality" refers to two or more. For example, multiple processing units refers to two or more processing units; multiple systems refers to two or more systems.

Here are a few technical points:

In the 3rd Generation Partnership Project (3GPP) standard, Long Term Evolution (LTE) provides three mechanisms for triggering measurement report reporting for the connected state: event trigger, periodic trigger and time period Sexually triggered. Several examples of event triggering are listed below,

A1: The measurement result of the serving cell is better than the threshold;

A2: The measurement result of the serving cell is worse than the threshold;

A3: The offset measurement result of the neighboring cell is better than that of the primary serving cell;

A4: The measurement result of the neighboring cell is better than the threshold;

A5: The measurement result of the primary serving cell/main second cell is worse than the threshold 1 and the measurement result of the neighboring cell is better than the threshold 2;

A6: The offset measurement result of the neighboring cell is better than that of the second cell;

B1: The inter-RAT (different system) neighbor measurement result is better than the threshold;

B2: The measurement result of the primary serving cell is worse than the threshold 1 and the inter-RAT neighbor cell is better than the threshold 2;

In the 3GPP standard, the triggering conditions for the UE in the idle state to perform cell reselection are given:

When the serving cell satisfies the cell selection received power value S _rxlev > the measurement threshold value S _IntraSearchP and the cell selection quality value S _qual > the measurement threshold value S _IntraSearchQ , the UE may choose not to trigger the neighbor cell measurement for cell reselection, otherwise , the UE will trigger neighbor cell measurement for cell reselection.

As mentioned above, in the existing solution, the measurement information reported by the UE does not include the poster height information of the terminal, and the altitude is not considered in the threshold of the triggering event for measurement reporting. If the original measurement trigger events, trigger thresholds, and cell reselection measurement thresholds are used, when the UE (such as a UAV terminal) flies above the antenna, the possible problems include: the measurement parameter thresholds are likely to frequently meet the existing trigger thresholds. (mainly in the connected state), resulting in frequent triggering of unnecessary measurement and reporting, consuming UE power, and affecting working time; although the signal in the neighboring cell is stronger, the measurement cannot be triggered in time because the relevant parameters of the serving cell are not lower than the threshold ( Mainly in idle state), resulting in strong interference and service performance degradation, etc.

Step 402: Measure according to the measurement configuration information to obtain measurement information, where the measurement information includes: the measurement result of the serving cell and the altitude information of the terminal;

The measurement result of the serving cell may be the measurement result obtained by the terminal performing the measurement triggering the measurement report reporting, or may be the measurement result obtained by the terminal performing the cell reselection measurement, for example, including: cell selection received power value and/or cell selection quality value, the measurement result of the serving cell may be the existing measurement result, which will not be described here.

The above-mentioned terminal altitude information may be an absolute value of altitude of the UE, or may also be a relative value of altitude between the UE and a network side device (eg, a base station), which is of course not limited to this.

Step 503: Determine the altitude factor according to the altitude information of the terminal;

In this embodiment of the present invention, altitude information of different terminals may correspond to one or more altitude factors, for example, 0-100 meters corresponds to altitude factor a, 100-200 meters corresponds to altitude factor b, and so on. It should be noted that, the altitude information of the terminal and the altitude factor may have a linear relationship, or may also have a nonlinear relationship.

Step 504: Adjust the threshold value of the triggering measurement reporting event according to the altitude factor, and obtain the adjusted threshold value of the triggering measurement reporting event;

For example, for event A1, when the measurement result of the serving cell meets the following conditions, the reporting of the measurement report is triggered:

Ms-Hys>Thresh Formula 1

Among them, Ms: the measurement result of this cell, excluding any offset;

Hys: The hysteresis parameter between entering and leaving the event. When the measurement result of the serving cell meets the following conditions, stop reporting the measurement report:

For example: timeToTrigger=Thresh_hight×timeToTrigger_basic, that is, the first specific time is equal to the time lag factor multiplied by the initial value of the time lag factor.

In this embodiment of the present invention, optionally, the method further includes:

Determine the time lag factor (Thresh_hight) according to the altitude information of the terminal and the corresponding relationship between the time lag factor (T_hight) and the altitude threshold value of the terminal (or called the terminal altitude threshold level sequence); The altitude information and the corresponding relationship between the initial value of the time lag factor and the altitude threshold value of the terminal, determine the initial value of the time lag factor (timeToTrigger_basic); according to the time lag factor and the initial value of the time lag factor, determine the first specific time ( timeToTrigger). For example: timeToTrigger=Thresh_hight×timeToTrigger_basic, that is, the first specific time is equal to the time lag factor multiplied by the initial value of the time lag factor.

Step 803: Determine an altitude factor according to the altitude information of the terminal;

Step 804: Adjust the measurement result of the serving cell according to the altitude factor to obtain the adjusted measurement result of the serving cell;

For example, in the standard TS 36.304, for an idle state terminal, S _rxlev >S _IntraSearchP and S _qual >S _IntraSearch should be satisfied without triggering cell reselection, where,

S _rxlev = Q _rxlevmeas (measured value of reception level of the serving cell under test) – (Q _rxlevmin (minimum reception level value in the cell) + Q _{rxlevminoffset} (minimum reception level of cell camping configured in the SIB)) – P _compensation (compensation value) – Q _offsettemp (the penalty offset after the UE fails to access the cell);

S _qual = Q _qualmeas (measured cell pilot channel quality) – (Q _qualmin (minimum cell signal quality)) + Q _{qualminoffset} (minimum received signal reception quality offset value)) – Q _offsettemp (after the UE fails to access the cell punitive bias).

You can consider using the following two methods:

Add the altitude factor Q _offsetaerial to the above formulas for S _rxlev and S _qual , for example:

S _rxlev =Q _rxlevmeas –(Q _rxlevmin +Q _{rxlevminoffset} ) – P _compensation –Q _offsettemp –Q _offsetaerial ;

S _qual =Q _qualmeas −(Q _qualmin +Q _{qualminoffset} )−Q _offsettemp −Q _offsetaerial .

In this embodiment of the present invention, optionally, in step 805, when the waiting time reaches a second specific time, trigger cell reselection, where the second specific time corresponds to the altitude information of the terminal.

In the embodiment of the present invention, optionally, the method further includes: determining the time lag factor according to the altitude information of the terminal and the corresponding relationship between the time lag factor and the altitude threshold value of the terminal; according to the altitude information of the terminal and the time The corresponding relationship between the initial value of the lag factor and the altitude threshold value of the terminal determines the initial value of the time lag factor; the second specific time is determined according to the time lag factor and the initial value of the time lag factor.
