Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive labor.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.
The terms "first" and "second," and the like, in the description and in the claims of embodiments of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first specific time and the second specific time, etc. are for distinguishing different specific times, and are not for describing 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 examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the embodiments of the present invention, "a plurality" means two or more unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; a plurality of systems refers to two or more systems.
Several technical points are introduced below:
in the third Generation Partnership project (3 rd Generation Partnership project,3 gpp) standard, long Term Evolution (LTE) provides three mechanisms for triggering measurement report reporting for the connected state: event triggering, periodic triggering, and time periodic triggering. Several examples of event triggers are listed below,
a1: the serving cell measurement result is better than the threshold;
a2: the serving cell measurement is worse than a threshold;
a3: the bias measurement result of the adjacent cell is superior to that of the main service cell;
a4: the neighbor cell measurement result is superior to the threshold;
a5: the measurement result of the main service cell/the main second cell is worse than the threshold 1 and the measurement result of the adjacent cell is better than the threshold 2;
a6: the bias measurement result of the adjacent cell is better than that of the second cell;
b1: the measurement result of the inter-RAT (inter-system) neighbor cell is superior to a threshold;
b2: the measurement result of the main service cell is worse than a threshold 1 and the inter-RAT adjacent cell is better than a threshold 2;
in the 3GPP standard, a trigger condition for cell reselection by an idle UE is given:
when the serving cell satisfies the cell selection receiving power value S rxlev >Measuring threshold value S IntraSearchP And a cell selection quality value S qual >Measuring threshold value S IntraSearchQ The UE may choose not to trigger the neighbor cell measurement for cell reselection, otherwise, the UE may trigger the neighbor cell measurement for cell reselection.
As described above, in the existing scheme, the UE reports the measurement information without including poster height information of the terminal, and the altitude is not considered in the threshold of the trigger event reported by the measurement. If the original measurement trigger event, trigger threshold and cell reselection measurement threshold are used, when a UE (e.g. a drone terminal) flies above an antenna, there may be problems including: the measurement parameter threshold frequently conforms to the existing trigger threshold (mainly in a connected state) with a high probability, so that unnecessary measurement and reporting are frequently triggered, the electric quantity of the UE is consumed, and the working time is further influenced; although the neighbor cell signal is stronger, since the serving cell related parameter is not lower than the threshold, the measurement cannot be triggered in time (mainly in an idle state), resulting in stronger interference and degradation of service performance.
Embodiments of the present invention are described below with reference to the accompanying drawings. The method for selecting the core network, the user terminal and the network side equipment provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a system adopting a fifth generation mobile communication (5 th generation, 5G) technology (hereinafter, both are referred to as a 5G system), and referring to fig. 3, it is a schematic structural diagram of a wireless communication system according to an embodiment of the present invention. As shown in fig. 3, the wireless communication system may include a network side device 30 and a terminal, for example, denoted as UE31, where the UE31 may communicate with the network side device 30. In practical applications, the connections between the above devices may be wireless connections, and fig. 3 illustrates solid lines for convenience and intuition of the connection relationships between the devices.
It should be noted that the communication system may include a plurality of UEs, and the network side device may communicate (transmit signaling or transmit data) with the plurality of UEs.
The network side device provided in the embodiment of the present invention may be a base station, and the network side device may be a commonly used base station, an evolved node base station (eNB), or a network side device in a 5G system (for example, a next generation base station (gNB) or a Transmission and Reception Point (TRP)).
The terminal provided by the embodiment of the invention can be an unmanned aerial vehicle terminal, a Mobile phone, a tablet Computer, a notebook Computer, a super Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA) and the like.
Referring to fig. 4, a flow of a measurement method is shown, where an execution subject of the method may be a terminal, and the method includes the following specific steps:
it should be noted that, in the embodiment of the present invention, the terminal may determine the measurement configuration information in an existing manner, for example: the terminal acquires the measurement configuration information configured by the network side equipment through a System Information Block (SIB).
The configuration information of the measurement serving cell may be used to configure the terminal to perform measurement for triggering measurement report reporting, or to configure the terminal to perform cell reselection measurement, and the configuration information of the measurement serving cell may adopt existing configuration information, which is not described herein again.
The configuration information for measuring the altitude of the terminal is used for configuring the terminal to measure the altitude.
the measurement result of the serving cell may be a measurement result obtained by the terminal performing measurement for triggering reporting of a measurement report, or may be a measurement result obtained by the terminal performing measurement for cell reselection, and includes, for example: the cell selection reception power value and/or the cell selection quality value, and the measurement result of the serving cell may be an existing measurement result, which will not be described herein.
The above-mentioned terminal altitude information may be an absolute altitude value of the UE, or may also be an altitude relative value between the UE and a network side device (e.g. a base station), which is not limited to this.
Thus, in the embodiment of the present invention, when reporting a trigger measurement report or performing processing of triggering cell reselection, the influence of the altitude information of the terminal on the trigger condition or the trigger threshold is considered, so as to avoid the problem that the terminal frequently or too late triggers measurement and reporting.
Referring to fig. 5, a flow of a measurement method is shown, where an execution subject of the method may be a terminal, and the method includes the following specific steps:
it should be noted that, in the embodiment of the present invention, the terminal may determine the measurement configuration information in an existing manner, for example: the terminal acquires the measurement configuration information configured by the network side equipment through a System Information Block (SIB).
The configuration information of the measurement serving cell may be measurement for configuring the terminal to trigger reporting of a measurement report, or measurement for configuring the terminal to perform cell reselection, and the configuration information of the measurement serving cell may adopt existing configuration information, which is not described herein again.
The configuration information for measuring the altitude of the terminal is used for configuring the terminal to measure the altitude.
the measurement result of the serving cell may be a measurement result obtained by the terminal performing measurement for triggering the measurement report, and is not described herein.
The terminal altitude information may be an absolute value of the altitude of the UE or may also be a relative value of the altitude of the UE and a network-side device (e.g., a base station).
in the embodiment of the present invention, the altitude information of different terminals may correspond to one or more altitude factors, such as 0-100 m for altitude factor a,100-200 m for altitude factor b, and so on. It should be noted that the altitude information and the altitude factor of the terminal may be in a linear relationship, or may also be in a non-linear relationship.
for example, for event A1, reporting a measurement report is triggered when the serving cell measurement result satisfies the following condition:
Ms-Hys > Thresh equation 1
Wherein, ms: the measurement result of the cell does not include any offset;
hys: and (3) a hysteresis parameter between entering and leaving the event, and when the measurement result of the serving cell meets the following conditions, stopping reporting the measurement report:
ms + Hys < Thresh equation 2
In step 504, the above equations 1 and 2 are adjusted to obtain the following equations:
Ms-Hys > Thresh +/-Delta adjusted equation 1
Adjusted equation 2 for Ms + Hys < Thresh +/- δ
The above δ represents an altitude factor.
And 505, when the measurement result of the serving cell meets the threshold value of the adjusted trigger measurement report event, performing processing of triggering the report of the measurement report.
In this embodiment of the present invention, optionally, in step 505, when the waiting time reaches a first specific time, the reporting of the measurement report is triggered, where the first specific time corresponds to the altitude information of the terminal, that is, different first specific times may be determined according to the altitude information of different terminals, and a corresponding relationship between the altitude information of the terminal and the first specific time may be determined by a protocol convention, a network side configuration, or the terminal, which is not limited thereto.
In the embodiment of the present invention, optionally, the method further includes:
determining a time lag factor (Thresh _ right) according to the altitude information of the terminal and the corresponding relation between the time lag factor (T _ right) and an altitude threshold value (or called an altitude threshold value grade sequence) of the terminal; determining a time delay factor initial value (timeToTrigger _ basic) according to the altitude information of the terminal and the corresponding relation between the time delay factor initial value and the altitude threshold value of the terminal; and determining a first specific time (timeToTrigger) according to the time lag factor and the initial value of the time lag factor. For example: timeToTrigger = Thresh _ right × timeToTrigger _ basic, i.e. the first specific time is equal to the time lag factor multiplied by the time lag factor initial value.
Therefore, in the embodiment of the invention, when the report of the triggered measurement report is reported, the influence of the altitude information of the terminal on the trigger threshold is considered, and the problem that the terminal triggers measurement and reporting frequently or too late is avoided.
Referring to fig. 6, a flow of a measurement method is shown, where an execution subject of the method may be a terminal, and the method includes the following specific steps:
in step 604, the above equations 1 and 2 are adjusted to obtain the following equations:
equation 1 after Ms-Hys +/-delta > Thresh adjustment
Ms + Hys +/-delta < Thresh adjusted equation 2
In this embodiment of the present invention, optionally, in step 605, when the waiting time reaches a first specific time, triggering measurement report reporting is performed, where the first specific time corresponds to altitude information of the terminal, that is, different first specific times may be determined according to altitude information of different terminals, and a corresponding relationship between the altitude information of the terminal and the first specific time may be determined by a protocol convention, a network side configuration, or the terminal, which is not limited thereto.
In this embodiment of the present invention, optionally, the method further includes:
determining a time lag factor (Thresh _ right) according to the altitude information of the terminal and the corresponding relation between the time lag factor (T _ right) and an altitude threshold value of the terminal (or called an altitude threshold value grade sequence of the terminal); determining a time delay factor initial value (timeToTrigger _ basic) according to the altitude information of the terminal and the corresponding relation between the time delay factor initial value and the altitude threshold value of the terminal; and determining a first specific time (timeToTrigger) according to the time lag factor and the initial value of the time lag factor. For example: timeToTrigger = Thresh _ right × timeToTrigger _ basic, i.e. the first specific time is equal to the time lag factor multiplied by the time lag factor initial value.
Thus, in the embodiment of the invention, when the report of the triggered measurement report is reported, the influence of the altitude information of the terminal on the triggering condition is considered, and the problem that the terminal triggers measurement and reporting frequently or too late is avoided.
Referring to fig. 7, a flow of a measurement method is shown in the figure, where an execution subject of the method may be a terminal, and the specific steps are as follows:
703, determining an altitude factor according to the altitude information of the terminal;
for example: in the standard TS 36.304, for an idle terminal, S needs to be satisfied without triggering cell reselection rxlev >S IntraSearchP And S qual >S IntraSearch The measurement threshold value S is determined according to the altitude factor IntraSearchP And measuringThreshold value S IntraSearchQ Adjustments are made, for example, extending from the original (0.. 31) to (0.. N), where N is greater than 31.
In this embodiment of the present invention, optionally, in step 705, when the waiting time reaches a second specific time, triggering cell reselection is performed, where the second specific time corresponds to the altitude information of the terminal.
In this embodiment of the present invention, optionally, the method further includes: determining a time lag factor according to the altitude information of the terminal and the corresponding relation between the time lag factor and the altitude threshold value of the terminal; determining an initial value of a time lag factor according to altitude information of the terminal and a corresponding relation between the initial value of the time lag factor and an altitude threshold value of the terminal; and determining a second specific time according to the time lag factor and the initial value of the time lag factor.
Thus, in the embodiment of the present invention, when the cell reselection is triggered, the influence of the altitude information of the terminal on the trigger threshold is considered, so as to avoid the problem that the terminal frequently or too late triggers measurement and reporting.
Referring to fig. 8, a flow of a measurement method is shown, where an execution subject of the method may be a terminal, and the method includes the following specific steps:
for example, in the standard TS 36.304, for an idle terminal, S needs to be satisfied without triggering cell reselection rxlev >S IntraSearchP And S qual >S IntraSearch Wherein
S rxlev ＝Q rxlevmeas (measured serving cell reception level measurement) - (Q) rxlevmin (minimum received level value in cell) + Q rxlevminoffset (minimum reception level of cell camping configured in SIB)) -P compensation (offset value) -Q offsettemp (punitive bias after failure of UE to access a cell);
S qual ＝Q qualmeas (measured cell pilot channel quality) - (Q) qualmin (minimum cell signal quality)) + Q qualminoffset (minimum received signal received quality offset value)) -Q offsettemp (punitive bias after failure of UE to access the cell).
Two approaches can be considered for implementation:
at the above-mentioned S rxlev And S qual Increasing the altitude factor Q in the formula offsetaerial 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, the triggering cell reselection is performed, 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 a time lag factor according to the altitude information of the terminal and the corresponding relation between the time lag factor and the altitude threshold value of the terminal; determining an initial value of a time lag factor according to altitude information of the terminal and a corresponding relation between the initial value of the time lag factor and an altitude threshold value of the terminal; and determining a second specific time according to the time lag factor and the initial value of the time lag factor.
