Description

A data preprocessing method, user equipment and computer storage medium

technical field

The present application relates to the technical field of information processing, and in particular, to a data preprocessing method, a user equipment (UE) and a computer storage medium.

Background technique

In LTE, the upper layer data stays in the PDCP layer after arrival. When the MCG or SCG has uplink resource authorization to reach the UE, the UE sends the data down to the RLC layer of the MCG or SCG, and finally sends it to the base station. The disadvantage of this processing method is that only when the uplink resource authorization reaches the UE, the UE will send the data from the PDCP to the RLC, generate the RLC PDU, and then generate the MAC PDU, which is too high for the instantaneous processing capability of the UE. In NR, this problem is further improved, that is, the UE is allowed to send data from PDCP to RLC before the uplink resource authorization reaches the UE, and generates RLC PDU, and then generates MAC PDU after the uplink resource authorization is reached. Alleviate the instantaneous processing capability requirement for the UE.

In NR, the UE is allowed to send data from PDCP to RLC before the uplink resource authorization reaches the UE, generate RLC PDU, and wait until the uplink resource authorization is reached, and then generate MAC PDU, so as to reduce the transient time for the UE by performing data preprocessing. processing power requirements. However, the cell that may preprocess data (especially in the case of dual connectivity) is not the cell that is about to receive uplink resource authorization, or it does not actually need data preprocessing, which may lead to unnecessary Data preprocessing occurs, thereby affecting the processing efficiency of the UE.

Detailed ways

In order to have a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Embodiment 1.

An embodiment of the present application provides a data preprocessing method, which is applied to a user equipment (UE), as shown in FIG. 1 , including:

Step 101: when performing data preprocessing, compare the amount of data with a threshold value to obtain a comparison result;

Step 102: Based on the comparison result, determine whether to perform data preprocessing on the target cell group.

The UE in this embodiment is mainly applied in a dual-connection scenario. For the dual-connection architecture, please refer to Figure 2. Under dual-connection, when the data bearer adopts the split bearer protocol architecture, for uplink and downlink, PDCP is located in a certain A cell group (CG) (a primary cell group (MCG) or a secondary cell group (SCG)), the CG is used as an anchor CG (anchor CG). The PDCP layer sends PDCP PDUs to the RLC of the MCG and/or SCG, thereby realizing data transmission using two connections. The data passes through the RLC and MAC of different CGs, and then reaches the corresponding MAC and RLC layers of the terminal (downlink) or base station (uplink) through the air interface, and finally converges to the PDCP, and finally delivers the data to the upper layer.

The bearer that connects the two RLCs and the MAC under the PDCP is called the split bearer. If the PDCP is located in the MCG, it is the MCG Split Bearer, and if the PDCP is located in the SCG, it is the SCG Split Bearer.

Further, based on the foregoing architecture, the data preprocessing described in this embodiment may be understood as performing preprocessing on data at the Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol) layer.

The triggering methods for the UE to perform data preprocessing in the foregoing step 101 may include the following:

method one,

Time-triggered; for example, a data preprocessing period may be set, that is, when the data preprocessing period is reached, it is determined that data preprocessing is required, and then step 101 is performed.

Method two,

event trigger;

For example, it may be that upper layer data arrives, lower layer data transmission is completed, or UE preprocessing capability changes.

Further, in the foregoing step 101, the threshold value may be delivered to the user equipment (UE) by the network side.

The threshold value is for at least part of the bearers corresponding to the UE; in this case, for different bearers, the threshold value may or may not be present;

Specifically, for the case where there is no threshold value, it can be equivalent to the case where the threshold value is 0 or the threshold value is infinite;

In the case of having a threshold value, the threshold values for the at least some of the bearers are all the same; or, the threshold values corresponding to each of the at least some of the bearers are the same or different.

It should be noted that at least part of the bearer may be one bearer, or may be two or more bearers.

For example, only one threshold value may be set, and one threshold value may be valid for some bearers in all bearers corresponding to the UE, while the remaining part bearers do not need to set the threshold value;

Alternatively, the threshold value of each bearer in the partial bearer may be different from each other.

Further, in the aforementioned step 101, the data amount is compared with the threshold value to obtain a comparison result, including:

Comparing the data amount with the threshold value to obtain a first comparison result or a second comparison result; wherein, the first comparison result indicates that the data amount is less than the threshold value, and the second comparison result indicates that the data amount is not less than the threshold value;

Correspondingly, in step 102, determining whether to perform data preprocessing on the target cell group based on the comparison result includes the following three processing situations:

Processing situation 1. When the comparison result is the first comparison result, it is determined that only the default cell group is allowed to perform data preprocessing;

Processing situation 2: When the comparison result is the first comparison result, it is determined not to perform data preprocessing on the target cell group;

Processing Scenario 3: When the comparison result is the second comparison result, it is determined that data preprocessing is allowed to be performed on the two cell groups at the same time.

That is, when the amount of data is less than the threshold, the UE only allows data preprocessing to the default CG; it is also possible that when the amount of data is less than the threshold, the UE does not preprocess the data, that is, no target cell is selected for data preprocessing. deal with;

When the amount of data is greater than the threshold (or equal to the threshold), the UE allows data preprocessing to two CGs at the same time.

The following describes the two scenarios in which the default CG performs preprocessing alone (scene 1) and two CGs perform data preprocessing at the same time (scene 2):

scene one,

The determining allows only the default cell group to perform data preprocessing, and the method further includes:

determining the amount of preprocessed data for the default cell group;

Correspondingly, the method further includes:

Obtain the upper limit value of the amount of preprocessed data configured by the network side for the UE.

That is to say, the network side will pre-configure the UE with an upper limit of the amount of data to be preprocessed.

Wherein, the amount of data to be determined for preprocessing includes one of the following:

The amount of data to be preprocessed is determined by the UE; that is, it can be determined by the UE itself;

Based on the upper limit value configured by the network side, it is determined that the amount of preprocessed data is less than the upper limit value; that is, an upper limit value can be configured by the network, and then the UE only needs to determine that the amount of preprocessed data is lower than the upper limit value;

Based on the upper limit value configured on the network side, the data volume of each preprocessing is determined until all the data to be processed is processed, or, until the data volume for which the preprocessing is completed reaches the upper limit value. That is, an upper limit value may be configured by the network, and then the UE needs to perform data preprocessing as much as possible until all the data in the PDCP is processed, or the upper limit value is reached.

In this scenario, the upper limit value may be the upper limit value for the default cell group, that is, the upper limit value is only set for the default cell group.

scene two,

The determining allows for data preprocessing to be performed on the two cell groups simultaneously, the method further comprising:

For each cell group in the two cell groups, determine the amount of preprocessed data corresponding to each cell group;

Correspondingly, the method further includes:

Obtain the upper limit value of the preprocessed data amount for each of the two cell groups configured by the network side for the UE.

That is, the network side will configure the upper limit value of the preprocessed data amount for the MCG and the SCG for the UE respectively; the two upper limit values may be the same or different.

Wherein, the amount of preprocessed data corresponding to each cell group is determined to include one of the following:

The amount of preprocessed data corresponding to each cell group is determined by the UE;

Based on the upper limit value configured by the network side for each cell group, it is determined that the amount of preprocessed data corresponding to each cell group is less than the corresponding upper limit value;

Based on the upper limit value configured by the network side for each cell group, the amount of data to be preprocessed each time is determined until all the data to be processed is processed, or, until the amount of data preprocessed reaches the amount configured for each cell group. Upper limit.

That is, in this scenario, the upper limit of the amount of preprocessed data for different cell groups can be determined by the UE itself;

Alternatively, the upper limit value can also be configured by the network for the two cell groups, such as MCG and SCG respectively, and then the UE only needs to determine that the amount of preprocessed data is lower than the upper limit value. For the preprocessing of MCG and SCG There are no other requirements for the amount of data;

In addition, there can also be a processing situation:

Obtain the upper limit value configured by the network side for each of the two cell groups;

determining a default cell group and a non-default cell group in the two cell groups, and determining the amount of data to be preprocessed in the default cell group each time based on the upper limit of the default cell group;

Judging whether the amount of data preprocessed in the default cell group reaches the upper limit value of the default cell group, and if it reaches the upper limit value of the non-default cell group, determine whether each data volume in the non-default cell group is determined based on the upper limit value of the non-default cell group The amount of data to be preprocessed;

Until whether the data to be processed is all processed, or until the amount of data that has been preprocessed in the non-default cell group reaches the upper limit of the non-default cell group.

That is, the upper limit of the network configuration can be given to MCG and SCG respectively, and then the UE needs to perform data preprocessing as much as possible, starting from the default CG to the non-default CG, until all the data in the PDCP is processed, or reaches Upper limit of MCG and SCG.

It can be seen that by adopting the above solution, when the UE needs to perform data preprocessing, the amount of data can be compared with the threshold value, and whether to perform data preprocessing through the target cell group is determined based on the comparison result. In this way, whether data preprocessing is required is determined according to the data volume of the UE, thereby ensuring data processing efficiency in the data preprocessing scenario.

Embodiment two,

An embodiment of the present application provides a user equipment (UE), as shown in FIG. 3 , including:

The comparison unit 31 is used to compare the data amount with the threshold value when performing data preprocessing to obtain a comparison result;

The processing unit 32 is configured to determine whether to perform data preprocessing on the target cell group based on the comparison result.

The UE in this embodiment is mainly applied in a dual-connection scenario. For the dual-connection architecture, please refer to Figure 2. Under dual-connection, when the data bearer adopts the split bearer protocol architecture, for uplink and downlink, PDCP is located in a certain A cell group (CG) (a primary cell group (MCG) or a secondary cell group (SCG)), the CG is used as an anchor CG (anchor CG). The PDCP layer sends PDCP PDUs to the RLC of the MCG and/or SCG, thereby realizing data transmission using two connections. The data passes through the RLC and MAC of different CGs, and then reaches the corresponding MAC and RLC layers of the terminal (downlink) or base station (uplink) through the air interface, and finally converges to the PDCP, and finally delivers the data to the upper layer.

The bearer that connects the two RLCs and the MAC under the PDCP is called the split bearer. If the PDCP is located in the MCG, it is the MCG Split Bearer, and if the PDCP is located in the SCG, it is the SCG Split Bearer.

Further, based on the foregoing architecture, the data preprocessing described in this embodiment may be understood as performing preprocessing on data at the Packet Data Convergence Protocol (PDCP, Packet Data Convergence Protocol) layer.

The triggering methods for UE to perform data preprocessing can be as follows:

method one,

Time-triggered; for example, a data preprocessing period may be set, that is, when the data preprocessing period is reached, it is determined that data preprocessing is required, and then step 101 is performed.

Method two,

event trigger;

For example, it may be that upper layer data arrives, lower layer data transmission is completed, or UE preprocessing capability changes.

Further, the threshold value may be delivered to the user equipment (UE) by the network side.

On the basis of FIG. 3 , as shown in FIG. 4 , the UE further includes:

A communication unit 33, configured to acquire the threshold value sent by the network side for at least part of the bearer of the UE;

Wherein, the thresholds for the at least some of the bearers are all the same; or, the thresholds corresponding to each of the at least some of the bearers are the same or different.

The threshold value is for at least part of the bearers corresponding to the UE; in this case, for different bearers, the threshold value may or may not be present;

Specifically, for the case where there is no threshold value, it can be equivalent to the case where the threshold value is 0 or the threshold value is infinite;

In the case of having a threshold value, the threshold values for the at least some of the bearers are all the same; or, the threshold values corresponding to each of the at least some of the bearers are the same or different.

For example, only one threshold value may be set, and one threshold value may be valid for some bearers in all bearers corresponding to the UE, while the remaining part bearers do not need to set the threshold value;

Alternatively, the threshold value of each bearer in the partial bearer may be different from each other.

Further, the comparison unit 31 is configured to compare the amount of data with the threshold value to obtain a first comparison result or a second comparison result; wherein, the first comparison result indicates that the data amount is less than the threshold value, and the second comparison result indicates the data The amount is not less than the threshold value;

Correspondingly, the processing unit 32, based on the comparison result, determines whether to perform data preprocessing on the target cell group, including the following three processing situations:

Processing situation 1. When the comparison result is the first comparison result, it is determined that only the default cell group is allowed to perform data preprocessing;

Processing situation 2: When the comparison result is the first comparison result, it is determined not to perform data preprocessing on the target cell group;

Processing Scenario 3: When the comparison result is the second comparison result, it is determined that data preprocessing is allowed to be performed on the two cell groups at the same time.

That is, when the amount of data is less than the threshold, the UE only allows data preprocessing to the default CG;

It is also possible that when the amount of data is less than the threshold value, the UE does not preprocess the data, that is, does not select any target cell for data preprocessing;

When the amount of data is greater than the threshold (or equal to the threshold), the UE allows data preprocessing to two CGs at the same time.

The following describes the two scenarios in which the default CG performs preprocessing alone (scene 1) and two CGs perform data preprocessing at the same time (scene 2):

scene one,

The processing unit 32 determines the amount of preprocessed data for the default cell group.

The processing unit 32 obtains the upper limit value of the preprocessed data volume configured by the network side for the UE; that is, the network side pre-configures the UE with the upper limit value of the preprocessed data volume.

Wherein, the amount of data to be determined for preprocessing includes one of the following:

The amount of data to be preprocessed is determined by the UE; that is, it can be determined by the UE itself;

Based on the upper limit value configured by the network side, it is determined that the amount of preprocessed data is less than the upper limit value; that is, an upper limit value can be configured by the network, and then the UE only needs to determine that the amount of preprocessed data is lower than the upper limit value;

Based on the upper limit value configured on the network side, the data volume of each preprocessing is determined until all the data to be processed is processed, or, until the data volume for which the preprocessing is completed reaches the upper limit value. That is, an upper limit value may be configured by the network, and then the UE needs to perform data preprocessing as much as possible until all the data in the PDCP is processed, or the upper limit value is reached.

In this scenario, the upper limit value may be the upper limit value for the default cell group, that is, the upper limit value is only set for the default cell group.

scene two,

The processing unit 32, for each cell group in the two cell groups, determines the amount of preprocessed data corresponding to each cell group;

The processing unit 32 further acquires the upper limit value of the preprocessed data amount for each of the two cell groups configured by the network side for the UE.

That is, the network side will configure the upper limit value of the preprocessed data amount for the MCG and the SCG for the UE respectively; the two upper limit values may be the same or different.

Wherein, the amount of preprocessed data corresponding to each cell group is determined to include one of the following:

Determine the amount of preprocessed data corresponding to each cell group by itself; (for example, according to the settings of the user, the processing unit can obtain the settings of the user, and then determine the amount of preprocessed data; it can also save the original data for each cell. The preset preprocessing data volume of the cell group).

Based on the upper limit value configured by the network side for each cell group, it is determined that the amount of preprocessed data corresponding to each cell group is less than the corresponding upper limit value;

Based on the upper limit value configured by the network side for each cell group, the amount of data to be preprocessed each time is determined until all the data to be processed is processed, or, until the amount of data preprocessed reaches the amount configured for each cell group. Upper limit.

That is, in this scenario, the upper limit of the amount of preprocessed data for different cell groups can be determined by the UE itself;

Alternatively, the upper limit value can also be configured by the network for the two cell groups, such as MCG and SCG respectively, and then the UE only needs to determine that the amount of preprocessed data is lower than the upper limit value. For the preprocessing of MCG and SCG There are no other requirements for the amount of data;

In addition, there can also be a processing situation:

The processing unit 32 obtains the upper limit value configured by the network side for each of the two cell groups;

determining a default cell group and a non-default cell group in the two cell groups, and determining the amount of data to be preprocessed in the default cell group each time based on the upper limit of the default cell group;

Judging whether the amount of data preprocessed in the default cell group reaches the upper limit value of the default cell group, and if it reaches the upper limit value of the non-default cell group, determine whether each data volume in the non-default cell group is determined based on the upper limit value of the non-default cell group The amount of data to be preprocessed;

Until whether the data to be processed is all processed, or until the amount of data that has been preprocessed in the non-default cell group reaches the upper limit of the non-default cell group.

That is, the upper limit of the network configuration can be given to MCG and SCG respectively, and then the UE needs to perform data preprocessing as much as possible, starting from the default CG to the non-default CG, until all the data in the PDCP is processed, or reaches Upper limit of MCG and SCG.

It can be seen that by adopting the above solution, when data preprocessing is required for UEs connected to two cell groups at the same time, the amount of data can be compared with the threshold value, and whether to perform data preprocessing through the target cell group is determined based on the comparison result. In this way, whether data preprocessing is required is determined according to the data volume of the UE, thereby ensuring data processing efficiency in the data preprocessing scenario.
