Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic flow chart illustrating an implementation of a method for determining a DRX offset parameter according to an embodiment of the present invention;
fig. 2 is a schematic structural diagram of a network-side device in an embodiment of the present invention.
Detailed Description
The inventor notices in the process of invention that:
the DRX offset parameter determines a period position of the MAC active state under the DRX on condition, and if there is a measurement GAP (GAP) measurement period conflict with a measurement GAP (GAP) measurement period and a candidate DRX offset parameter set element cannot be found, it may cause a DRX parameter configuration failure.
When the DRX parameter configuration fails, the terminal cannot enter the DRX state, so that the probability that the terminal is in the DRX state is reduced, and the power saving performance of the terminal is reduced; the configuration of the DRX offset parameter is one of the important factors of DRX performance.
Based on this, the embodiment of the present invention provides a technical solution for determining a candidate set of DRX offset parameters based on the above factors, and the following describes a specific embodiment of the present invention with reference to the drawings.
Fig. 1 is a schematic flowchart of an implementation of a method for determining a DRX offset parameter, as shown in the figure, the method may include:
step 101, determining a DRX offset parameter candidate set;
step 102, adjusting a DRX offset parameter candidate set according to a threshold value of a DRX parameter DRX-onduration timer and/or an initial value of the DRX parameter DRX-onduration timer, where the threshold value of the DRX parameter DRX-onduration timer is set according to a power saving requirement of a terminal, and the initial value of the DRX parameter DRX-onduration timer is set according to a transmission requirement of a guaranteed service;
step 103, selecting DRX offset parameters from the DRX offset parameter candidate set.
In implementation, the DRX offset parameter selected from the DRX offset parameter candidate set is a DRX offset parameter that is less than or equal to a threshold value of the DRX parameter DRX-onDurationTimer; or the like, or, alternatively,
is a DRX offset parameter that is greater than the initial value of the DRX parameter DRX-onDurationTimer when it is greater than the threshold value of the DRX parameter DRX-onDurationTimer.
Specifically, in the solution, under the condition that the DRX offset parameter candidate set is determined to be failed, the selection range of the DRX parameter DRX-onDurationTimer may be increased based on the threshold value of the DRX parameter DRX-onDurationTimer, and whether an available DRX offset parameter exists is determined; if no available DRX Offset parameter exists, further judging whether the initial time length of the DRX-on duration timer can be ensured, and judging whether available DRX Offset value exists under the condition that the service transmission can be ensured even if the time conflicts with the GAP measurement time and the service transmission can be ensured, thereby improving the probability of the terminal entering the DRX under the condition of ensuring the service transmission performance; under the condition that an available DRX offset parameter set exists, the DRX offset parameter is selected based on the SRS sending interval condition, and the accuracy of channel quality evaluation is improved.
The following is a description of the specific implementation in the form of steps.
First, set the threshold value of DRX parameter DRX-onDurationTimer.
Specifically, the threshold value of the DRX parameter DRX-onDurationTimer is set to
Figure BDA0002283469460000071
The values mean: if the value of DRX parameter DRX-onDuration timer is larger than the set threshold value of DRX-onDuration timer
Figure BDA0002283469460000072
The significance of DRX power saving is artificially lost.
Therefore, the threshold value of the DRX parameter DRX-onDurationTimer in implementation may be set according to the power saving requirement of the terminal.
And secondly, acquiring an initial value of a DRX parameter DRX-onDurationTimer.
Specifically, the initial value of the DRX parameter DRX-onDurationTimer is set as
Figure BDA0002283469460000073
In implementation, the determination scheme of the initial value of the DRX parameter DRX-onDurationTimer is not limited, for example, the initial value of the DRX parameter DRX-onDurationTimer is determined based on the traffic characteristics
Figure BDA0002283469460000074
To ensure efficient transmission of traffic.
Since the initial value of the DRX parameter DRX-onDurationTimer is to ensure effective transmission of the service, the value may be set according to the transmission requirement of the guaranteed service.
And thirdly, determining a DRX offset parameter candidate set.

otherwise, go to four.
Fourthly, when the DRX offset parameter candidate set is adjusted according to the threshold value of the DRX parameter DRX-onDuration timer, the method comprises the following steps:
if the DRX offset parameter candidate set does not have selectable DRX offset parameters, selecting the value of the DRX parameter DRX-onDuration timer configuration which is greater than and closest to the last time within the value range of the DRX parameter DRX-onDuration timer, and taking the value as the value of the current DRX parameter DRX-onDuration timer.
Specifically, the specific manner of increasing the selection range of the DRX parameter DRX-onDurationTimer and determining whether the available DRX Offset value exists may be as follows:

Figure BDA0002283469460000081
The specific determination method of the DRX offset parameter candidate set is not limited in implementation, and one possible method is, for example, setting based on factors such as avoiding conflict between DRX MAC Active state time and measurement time of the GAP.
If DRX Offset candidate set
Figure BDA0002283469460000082
The number of the elements in (1) is 0, go to step B), otherwise, go to six.
And fifthly, in implementation, adjusting the DRX offset parameter candidate set according to the initial value of the DRX parameter DRX-onDurationTimer:
and if the value of the current DRX parameter DRX-onDuration timer exceeds the threshold value of the DRX parameter DRX-onDuration timer, selecting the value of the DRX parameter DRX-onDuration timer configuration which is larger than and closest to the last ACTIVE state time configuration within the value range of the DRX parameter DRX-onDuration timer as the value of the ACTIVE state time configuration.
Specifically, it may further determine whether there is a value of available DRX Offset by determining whether the initial time length of the DRX on duration timer can be guaranteed. The method comprises the following specific steps:
A) obtaining the initial value of DRX parameter DRX-onDurationTimer, and setting the value as
Figure BDA0002283469460000093
j＝0。
In practice, the determination method of the initial value of the DRX parameter DRX-onDurationTimer is not limited, but one feasible method is, for example, determining the initial value of the DRX parameter DRX-onDurationTimer based on the traffic characteristics

Sixthly, when the DRX offset parameter is selected from the DRX offset parameter candidate set, the method further comprises the following steps:
and selecting the DRX offset parameter from the DRX offset parameter candidate set according to the SRS (Sounding Reference Signal) period.
In specific implementation, selecting a DRX offset parameter from a DRX offset parameter candidate set according to an SRS period includes:
