Description

Data preprocessing method, user equipment and computer storage medium

Technical Field

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

Background

In LTE, the upper layer data stays in a PDCP layer after reaching, and when MCG or SCG has uplink resource authorization to reach UE, the UE sends the data downwards to an RLC layer of the MCG or SCG so as to finally send the data to a base station end. Such a processing method is bad in that the UE will send data from the PDCP to the RLC only when the uplink resource grant reaches the UE, and generate RLC PDU, and further generate MAC PDU, which is too high for the instantaneous processing capability of the UE. In NR, the problem is further improved by allowing the UE to send data from PDCP to RLC before the uplink resource grant reaches the UE, generating RLC PDU, and waiting until the uplink resource grant reaches, further generating MAC PDU, thereby alleviating the instantaneous throughput requirement for the UE.

In the NR, the UE is allowed to transmit data from the PDCP to the RLC before the uplink resource authorization reaches the UE, and an RLC PDU is generated, and after the uplink resource authorization reaches, an MAC PDU is further generated, so that the requirement of the instantaneous processing capability of the UE is relieved by data preprocessing. However, a cell that may pre-process data (especially in the case of dual connectivity), is not a cell that is about to receive the uplink resource grant, or actually does not need data pre-processing, which may cause unnecessary data pre-processing, thereby affecting the processing efficiency of the UE.

Detailed Description

So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.

The first embodiment,

An embodiment of the present application provides a data preprocessing method, which is applied to User Equipment (UE), and as shown in fig. 1, includes:

step 101: when data preprocessing is carried out, the data quantity is compared with a threshold value to obtain a comparison result;

step 102: and determining whether to perform data preprocessing on the target cell group based on the comparison result.

The UE in this embodiment is mainly applied to a dual connectivity scenario, and regarding a dual connectivity architecture, see fig. 2, in the dual connectivity scenario, when a split bearer protocol architecture is adopted for data bearer, for uplink and downlink, a PDCP is located in a certain Cell Group (CG) (a primary cell group (MCG) or a Secondary Cell Group (SCG)), and then the CG is used as an anchor CG (anchor CG)). The PDCP layer transmits PDCP PDUs to the RLC of the MCG and/or SCG, thereby enabling data transmission using two connections. The data passes through RLC and MAC of different CG, then reaches corresponding MAC and RLC layers of a terminal (downlink) or a base station (uplink) through an air interface, finally converges to PDCP, and finally delivers the data to a high layer.

This one Bearer, in which the PDCP is connected to the two RLC and MAC respectively, is called Split Bearer, if the PDCP is located in the MCG, the MCG Split Bearer, and if the PDCP is located in the SCG, the SCG Split Bearer.

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

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

in a first way,

Triggering time; 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.

The second way,

Triggering an event;

for example, it may be the upper layer data arrival, the lower layer data transmission is completed, or the UE preprocessing capability changes.

Further, in the foregoing step 101, the threshold may be issued to the User Equipment (UE) by the network side.

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

specifically, for the case where there is no threshold, it may be equivalent to the case where the threshold is 0 or the threshold is infinite;

for the case of threshold values, the threshold values for the at least part of bearers are all the same; or, the corresponding threshold value for each of the at least some bearers is the same or different.

It is noted that at least part of the bearers may be 1 bearer or may be 2 or more bearers.

For example, only one threshold may be set, where one threshold may be valid for a part of all bearers corresponding to the UE, and the remaining part of bearers do not need to be set with the threshold;

alternatively, the threshold value of each bearer in the partial bearers may be different.

Further, in step 101, the comparing the data amount with the threshold to obtain a comparison result includes:

comparing the data quantity with a threshold value to obtain a first comparison result or a second comparison result; the first comparison result represents that the data quantity is smaller than a threshold value, and the second comparison result represents that the data quantity is not smaller than the threshold value;

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

processing the first condition, and determining to allow only a default cell group to perform data preprocessing when the comparison result is a first comparison result;

processing the second situation, and when the comparison result is the first comparison result, determining not to perform data preprocessing on the target cell group;

and processing the third case, and determining that the data preprocessing is allowed to be simultaneously performed on the two cell groups when the comparison result is the second comparison result.

Namely, when the data volume is smaller than the threshold value, the UE only allows to carry out data preprocessing to the default CG; it is also possible that when the data amount is smaller than the threshold value, the UE does not perform data preprocessing, that is, does not select any target cell for data preprocessing;

when the data amount is larger than the threshold value (or equal to the threshold value), the UE allows data preprocessing to be performed to the two CGs at the same time.

The following description is made for two scenarios, in which the default CG performs preprocessing alone (scenario one) and the two CGs perform data preprocessing simultaneously (scenario two), respectively:

scene one,

The determining allows data pre-processing only for a default cell group, the method further comprising:

determining a pre-processed data amount for the default cell group;

correspondingly, the method further comprises the following steps:

and acquiring an upper limit value of the preprocessed data volume configured for the UE by the network side.

That is, the network side configures the upper limit of the amount of data to be preprocessed for the UE in advance.

Wherein the determining the pre-processed data amount comprises one of:

determining, by the UE, an amount of data to preprocess; i.e. may be decided by the UE itself;

determining that the preprocessed data volume is smaller than an upper limit value configured on the network side; that is, the network may configure an upper limit value, and then the UE only needs to determine that the amount of the preprocessed data is lower than the upper limit value;

and determining the data volume of each preprocessing based on the upper limit value configured on the network side until the data needing to be processed is completely processed or the data volume of the data needing to be preprocessed reaches the upper limit value. That is, the network may configure an upper limit value, and then the UE needs to perform data preprocessing as much as possible until all data in the PDCP are processed or the upper limit value is reached.

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

Scene two,

The determination allows data pre-processing to two cell groups simultaneously, the method further comprising:

determining a pre-processed data volume corresponding to each cell group aiming at each cell group in the two cell groups;

correspondingly, the method further comprises the following steps:

and acquiring an upper limit value of the preprocessed data volume of each cell group in the two cell groups, which is configured for the UE by the network side.

Namely, the network side configures the upper limit values of the preprocessed data volumes for the MCG and the SCG for the UE respectively; the two upper limit values may be the same or different.

Wherein the determining of the pre-processed data amount corresponding to each cell group includes one of:

determining the preprocessed data volume corresponding to each cell group by the UE;

determining that the preprocessed data volume corresponding to each cell group is smaller than the corresponding upper limit value based on the upper limit value configured by the network side for each cell group;

and determining the data volume preprocessed each time based on the upper limit value configured by the network side for each cell group until the data to be processed is completely processed or the data volume preprocessed is up to the upper limit value configured by each cell group.

That is, in this scenario, the upper limit values of the preprocessed data amounts for different cell groups may all be determined by the UE itself;

alternatively, the network may also configure an upper limit value for each of the two cell groups, such as MCG and SCG, and then the UE only needs to determine that the amount of preprocessed data is lower than the upper limit value, and there is no other requirement for the amount of preprocessed data of MCG and SCG;

in addition, there may be a processing case:

acquiring an upper limit value configured by a network side for each cell group in two cell groups;

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

judging whether the data volume preprocessed in the default cell group reaches the upper limit value of the default cell group, if so, determining the data volume preprocessed in each non-default cell group based on the upper limit value of the non-default cell group;

until all data needing to be processed is processed or until the amount of the data which are preprocessed in the non-default cell group reaches the upper limit value of the non-default cell group.

That is, the network may configure the upper limit value for the MCG and the SCG, and then the UE needs to perform data preprocessing as much as possible, and make non-default CGs from the default CG until all data in the PDCP are processed, or the upper limit values of the MCG and the SCG are reached.

Therefore, by adopting the scheme, when the UE needs to perform data preprocessing, the data amount can be compared with the threshold value, and whether the data preprocessing is performed through the target cell group is determined based on the comparison result. Therefore, whether data preprocessing is needed or not is judged according to the data quantity of the UE, and the data processing efficiency under the data preprocessing scene is guaranteed.

wherein the threshold values for the at least partial bearers are all the same; or, the corresponding threshold value for each of the at least some bearers is the same or different.

Further, the comparing unit 31 is configured to compare the data amount with a threshold value to obtain a first comparison result or a second comparison result; the first comparison result represents that the data quantity is smaller than a threshold value, and the second comparison result represents that the data quantity is not smaller than the threshold value;

accordingly, 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 cases:

Namely, when the data volume is smaller than the threshold value, the UE only allows to carry out data preprocessing to the default CG;

it is also possible that when the data amount is smaller than the threshold value, the UE does not perform data preprocessing, that is, does not select any target cell for data preprocessing;

scene one,

A processing unit 32, configured to obtain an upper limit value of the pre-processed data amount configured for the UE by the network side; that is, the network side configures the upper limit of the amount of data to be preprocessed for the UE in advance.

Wherein the determining the pre-processed data amount comprises one of:

Scene two,

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

determining the preprocessed data volume corresponding to each cell group by the self; (for example, the pre-processed data amount may be determined by the processing unit according to the setting of the user, or the pre-processed data amount for each cell group may be originally stored in the processing unit).

in addition, there may be a processing case:

a processing unit 32, configured to obtain an upper limit value configured by the network side for each of the two cell groups;

Therefore, by adopting the scheme, when the data preprocessing is needed for the UE which is simultaneously connected with the two cell groups, the data quantity is compared with the threshold value, and whether the data preprocessing is carried out through the target cell group is determined based on the comparison result. Therefore, whether data preprocessing is needed or not is judged according to the data quantity of the UE, and the data processing efficiency under the data preprocessing scene is guaranteed.
