Abstract

Disclosed are a data preprocessing method, a network device, a user equipment (UE), and a computer storage medium, comprising: determining a preprocessing threshold with respect to a user equipment (UE); and transmitting the preprocessing threshold to the UE.

Description

Data preprocessing method, network device, user equipment, and computer storage medium

Technical field

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

Background technique

In LTE, the upper layer data arrives at the PDCP layer after the arrival of the upper layer data. When the MCG or the SCG has the uplink resource grant to reach the UE, the UE then sends the data down to the RLC layer of the MCG or the SCG, and finally sends the data to the base station. The disadvantage of this type of processing is that the UE will send the data from the PDCP to the RLC, generate the RLC PDU, and generate the MAC PDU, even if the uplink resource grant reaches the UE. The instantaneous processing capability of the UE is too high. In the NR, the problem is further improved, that is, the UE is allowed to send data from the PDCP to the RLC before the uplink resource grant reaches the UE, and the RLC PDU is generated, and then the uplink resource grant is reached, thereby generating the MAC PDU. The transient processing capability requirements for the UE are alleviated.

However, the pre-processing also has a certain negative effect. For example, when the UE pre-processes a part of the data and puts it in the RLC layer of the MCG, there is no uplink resource authorization from the MCG for a long time after the result. Part of the data is stuck in the RLC layer of the MCG. Although the user can perform uplink data transmission through the SCG uplink resource authorization, the data sent by the RLC layer of the MCG is not sent out, and the subsequent data transmission of the PDCP cannot be performed. It may cause the UE to actively discard the data of the RLC layer of the MCG, which affects the continuous transmission of data.

Detailed ways

The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1

The embodiment of the present invention provides a data preprocessing method, which is applied to a network device, as shown in FIG. 1a, and includes:

Step 101: Determine a pre-processing threshold for the user equipment UE.

Step 102: Send the pre-processing threshold to the UE.

The network device in this embodiment may be a device with a management function on the network side, for example, may be a network management device in the network, and may also be a device on the core network side. In this embodiment, the entity of the network device is not limited. .

This application can be processed for the following two scenarios:

scene one,

Before the step 101, that is, before the determining the pre-processing threshold for the UE, the method further comprises: receiving a pre-processing capability related value sent by the UE.

In this scenario, the correlation value of the pre-processing capability sent by the UE is obtained in advance, and the pre-processing threshold is determined based on the correlation value.

The correlation value of the preprocessing capability may include at least one of the following:

This value may be an instantaneous value, that is, the amount of data preprocessed by the user at the current time (instantaneous); wherein the instantaneous time may be composed of the current time and a period of time before it, for example, pre-processing within N ms before the current time The amount of data.

The value may be a threshold value, that is, an upper limit of the amount of data preprocessed by the user; for example, a threshold value that can be set by the UE itself, or a maximum amount of data that the user performs preprocessing within a period of time as an upper limit value.

This value can be a per UE value indicating that this pre-processing capability applies to each bearer or to the sum of all bearers;

It can also be a per bearer value indicating that this preprocessing capability applies to a particular bearer; in this case, not every bearer needs such a value (for example, this value is only needed for split bearers).

There is also a case where the value may be a different value for a different cell group (CG) to be carried. For example, the UE reports a value for each of the MCG and the SCG.

Further, in this scenario, correspondingly, in step 101, the determining a pre-processing threshold for the UE includes: selecting a value lower than a pre-processing capability correlation value of the UE, as a pre-targeting for the UE Handle the threshold.

That is to say, in this scenario, since the value sent by the network may be set after considering the user pre-processing capability, when the pre-processing threshold is allocated to the UE, the selected value must be lower than the capability reported by the user.

Further, based on the foregoing processing, the method may further include:

The determining a pre-processing threshold for the UE includes:

For each of the at least one bearer of the UE, a different pre-processing threshold is set for each bearer. In this case, because different QoS requirements of different bearers are different, the threshold may have different values for different bearers; wherein the pre-processing threshold of each bearer is smaller than the user pre-processing number. The upper limit of the amount of data, or the sum of the pre-processing thresholds corresponding to all the bearers is less than the upper limit of the amount of pre-processed data of the user.

Or, for a part of the at least one bearer of the UE, the pre-processing threshold is not set; since some bearers are not affected by the pre-processing (for example, a single-connection bearer), the threshold is not required to be configured for the bearer. For this kind of bearer, the user can decide the amount of data to be preprocessed.

Or, when at least two cell groups connected by the UE are used, setting a pre-processing threshold value for at least one of the at least two cell groups.

Since the processing for the MCG and the SCG comes from different network nodes in the dual connectivity scenario, the MCG and the SCG can respectively send different threshold values for the connection, thereby limiting the amount of preprocessed data pushed from the PDCP to the MCG RLC and the slave. The amount of preprocessed data that PDCP pushes to the SCG RLC.

The pre-processing threshold corresponding to each cell group may also be smaller than the pre-processing capability related value sent by the UE;

Or the sum of the pre-processing thresholds corresponding to all the cell groups is smaller than the pre-processing capability related value sent by the UE;

Or, the pre-processing threshold corresponding to the partial cell group in the entire cell group is limited, wherein the pre-processing threshold value of the partial cell group is smaller than the pre-processing capability related value sent by the UE, or part of The sum of the pre-processing thresholds of the cell group is smaller than the pre-processing capability related value sent by the UE.

Further, in this scenario, the setting of the pre-processing threshold may also be performed according to the amount of data to be granted to the UE.

The amount of data to be authorized to the UE is determined by the network side; correspondingly, the pre-processing threshold may not exceed the amount of data.

Scene 2,

The difference from the scenario is that the scenario may not acquire the pre-processing capability related value sent by the UE, that is, the pre-processing threshold of the UE is determined only by the network device in the scenario. details as follows:

The determining a pre-processing threshold for the UE includes:

For each of the at least one bearer of the UE, a different pre-processing threshold is set for each bearer. In this case, the threshold may have different values for different bearers due to different QoS requirements of different bearers.

For the dual-connection architecture, see Figure 1b. Under dual connectivity, when the data bearer adopts the split bearer protocol architecture, for uplink and downlink, the PDCP is located in a certain cell group (CG) (main cell group (MCG) or auxiliary. The cell group (SCG)), the CG acts as an anchor CG. The PDCP layer sends the PDCP PDU to the RLC of the MCG and/or SCG, thereby enabling data transmission using two connections. The data passes through the RLC and MAC of different CGs, then reaches the terminal (downlink) through the air interface or the corresponding MAC and RLC layers of the base station (uplink), and finally aggregates to the PDCP, and finally delivers the data to the upper layer.

The one that connects the two RLCs and the MACs respectively under the PDCP is called a split bearer. If the PDCP is located in the MCG, it is the MCG Split Bearer. If the PDCP is located, SCG is SCG Split Bearer.

Further, in this scenario, since the correlation value of the pre-processed data reported by the UE is not required to be acquired, the network device may perform the setting of the pre-processing threshold according to the amount of data that is expected to be granted to the UE by the uplink resource.

The amount of data that is expected to be granted to the UE by the uplink resource is determined by the network side; correspondingly, the pre-processing threshold may not exceed the amount of data.

It can be seen that, by adopting the foregoing solution, the configuration of the pre-processed data amount can be performed by the network side for the UE; thus, the UE can perform subsequent processing according to the pre-configured pre-processed data amount, thereby avoiding the situation between the UE and the network side. The amount of pre-processed data does not match the problem of data retention, which ensures the data processing efficiency of the UE.

Embodiment 2

The embodiment of the present invention provides a data preprocessing method, which is applied to a user equipment (UE), as shown in FIG. 2, and includes:

Step 201: Receive a pre-processing threshold sent by the network side.

Step 202: Determine whether to perform a pre-processing operation based on the pre-processing threshold.

Before the step 201, that is, before receiving the pre-processing threshold sent by the network side, the pre-processing capability related value may also be sent to the network side, or the pre-processing capability related value may not be sent.

In the scenario that the pre-processing capability-related value is sent to the network side, the related value of the pre-processing capability needs to be related, and the correlation value of the pre-processing capability may include at least one of the following:

The upper limit value of the amount of data to be preprocessed by the UE; the value may be an instantaneous value, that is, the amount of data preprocessed by the user at the current time (instantaneously); wherein the instant may be composed of the current time and a period of time before, For example, the amount of preprocessed data within N ms before the current time.

The upper limit value of the amount of data to be preprocessed by the UE; the value may be a threshold value, that is, an upper limit of the amount of data preprocessed by the user; for example, a threshold value that can be set by the UE itself, or may be a period of time The maximum amount of data that the internal user performs preprocessing is taken as the upper limit value.

The sum of the pre-processed data amount applicable to at least one bearer in the UE or the pre-processed data amount of all bearers in the UE; this value may be a per UE value, indicating that this pre-processing capability is applicable to each Bearer, or applicable to the sum of all bearers;

In another case, the pre-processed data volume corresponding to each of the at least two cell groups corresponding to the UE; that is, the value may be a different bearer in the corresponding different cell group (CG). The value, for example, the UE reports a value for each of the MCG and the SCG.

Further, the determining, according to the pre-processing threshold, whether to perform a pre-processing operation includes the following two cases:

Case 1: If the pre-processed data amount equals or exceeds the pre-processing threshold, it is determined that the pre-processing operation is not performed. The pre-processing operation may be performed in a radio link control (RLC) layer function, that is, if the pre-processed data amount in the RLC has equalized or exceeded the threshold value, it is determined that the pre-processing operation is not performed.

Case 2: obtaining the data amount corresponding to the currently preprocessed data packet; summing the data amount of the completed preprocessed data with the data amount corresponding to the currently preprocessed data packet, and obtaining the expected preprocessed data amount; If the expected amount of pre-processed data is equal to or exceeds the pre-processing threshold, it is determined that the pre-processing operation is not performed.

The current processing situation is to estimate the estimated amount of processed data of the UE, and to determine whether to perform pre-processing based on the estimated amount of data, that is, if the UE continues processing for the current data packet, the amount of pre-processed data in the RLC will exceed the threshold. Value, the UE does not perform preprocessing operations.

The following is a description of the general flow of the application for the foregoing embodiment:

Step 1 (optional): The user reports a pre-processing capability related value to the network;

This value can be an instantaneous value, that is, the amount of data preprocessed by the user at the current time;

This value can be a threshold value, that is, an upper limit of the amount of data preprocessed by the user;

It can also be a per bearer value indicating that this preprocessing capability is appropriate for a particular bearer.

In this case, not every bearer needs such a value (for example, this value is only needed for split bearers);

This value may be one value for each CG, that is, the UE reports a value for each of the MCG and the SCG.

- Step 2 (required): The network sends a pre-processing threshold to the UE, thereby limiting the amount of pre-processed data of the UE;

If there is step one, the value sent by the network may be set after considering the user pre-processing capability, that is, the threshold must be lower than the capability reported by the user.

Because different QoS requirements of different bearers are different, the threshold may have different values for different bearers;

Since some bearers are not affected by the pre-processing (for example, a single-connection bearer), there is no need to configure the threshold for these bearers. For such bearers, the user can determine the amount of pre-processed data.

- Step 3 (required): After the UE receives the threshold from the network, if the amount of pre-processed data in the RLC has equaled or exceeded the threshold, or if the UE continues for the current packet The amount of pre-processed data in the RLC will exceed the threshold; then the UE will not perform pre-processing operations.

An embodiment of the present invention provides a network device, as shown in FIG. 3, including:

The first processing unit 31 determines a pre-processing threshold value for the user equipment UE;

The first communication unit 32 sends the pre-processing threshold to the UE.

This application can be processed for the following two scenarios:

scene one,

Before the determining the pre-processing threshold for the UE, the first communications unit 32 receives the pre-processing capability related value sent by the UE.

Further, in this scenario, correspondingly, the first processing unit 31 selects a value lower than the pre-processing capability correlation value of the UE as a pre-processing threshold value for the UE.

Further, based on the foregoing processing, the method may further include:

The first processing unit 31 sets different pre-processing thresholds for each bearer in at least one bearer of the UE. In this case, because the QoS requirements of different bearers are different, the threshold may have different values for different bearers; wherein the pre-processing threshold of each bearer is smaller than the upper limit of the amount of user pre-processed data, or The sum of the pre-processing thresholds corresponding to all bearers is less than the upper limit of the amount of pre-processed data of the user.

Since the processing for MCG and SCG comes from different network nodes in the dual connectivity scenario, Therefore, the MCG and the SCG can respectively transmit different threshold values for the connection, thereby limiting the amount of pre-processed data pushed from the PDCP to the MCG RLC and the amount of pre-processed data pushed from the PDCP to the SCG RLC.

Case 2, the second processing unit 42 acquires the data amount corresponding to the currently preprocessed data packet; and sums the data amount of the completed preprocessed data with the data amount corresponding to the currently preprocessed data packet to obtain the expected preprocessed data. The amount of data; if the expected amount of pre-processed data is equal to or exceeds The pre-processing threshold value determines that no pre-processing operation is performed.
