Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an information processing method, apparatus, device, and readable storage medium. Background Art

[0002] During the transmission of New Radio (NR) user-plane data packets, if there are some lost data packets, the time (Treordering) that the Packet Data Convergence Protocol (PDCP) layer waits for the Radio Link Control (RLC) to recover and deliver the lost data packets can be referred to as the duration of the reordering timer.

[0003] In the prior art, there are multiple optional values for the PDCP reordering timer, and the specific configuration value is statically configured by Radio Resource Control (RRC) signaling. However, if the duration of the reordering timer is set too high, it may cause more data packets to be delayed, affecting the performance of higher layers; if the reordering timer is set too low, it may cause the PDCP receive window to slide too fast, resulting in too many data packets being discarded, and there may also be many loopholes or gaps when delivering data packets to higher layers, causing higher layers to require more costs to complete data transmission.

[0004] It can be seen from this that the existing technology method cannot guarantee the data transmission efficiency and accuracy of the user plane of the radio access network. Summary of the Invention

[0130] In the embodiment of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0131] In the embodiment of the present application, the term "a plurality of" refers to two or more, and other quantifiers are similar.

[0132] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0133] See Figure 1 , Figure 1 It is the flowchart of the information processing method provided by the embodiment of the present application, which is applied to the receiving end. As Figure 1 shown, it includes the following steps:

[0134] Step 101, obtain the channel quality parameter and the service QoS parameter.

[0135] As Figure 2As shown in the figure, in the embodiment of the present application, the receiving end may include: a first protocol layer (L2), a second protocol layer (L1), and a third protocol layer (L3). Among them, the first protocol layer has a reordering function; the second protocol layer is the lower layer (or called the lower layer) of the first protocol layer, and is used to provide channel quality parameters; the third protocol layer is the upper layer (or called the upper layer) of the first protocol layer, and is used to provide service QoS parameters.

[0136] In this step, the first protocol layer obtains the channel quality parameters from the second protocol layer and obtains the service QoS parameters from the third protocol layer.

[0137] Specifically, in the embodiment of the present application, the third protocol layer (higher layer) has the function of obtaining service QoS requirements. After obtaining the service QoS parameters (or called service QoS requirement information), it notifies the first protocol layer of the service QoS parameters through the inter-layer primitive L3_L2_QOS_REQ message. The second protocol layer (lower layer) has the function of measuring and obtaining the channel quality. After measuring and obtaining the channel quality situation, it notifies the first protocol layer of the channel quality parameters through the inter-layer primitive L1_L2_CQI_IND message. The first protocol layer has the function of receiving relevant messages of service QoS parameters and channel quality parameters.

[0138] Step 102: Determine the duration of the first reordering timer according to the channel quality parameters and the service QoS parameters.

[0139] Facing different service QoS requirements, the duration of the reordering timer needs to adapt to the corresponding service QoS requirements, and a reasonable duration of the reordering timer is set according to different service QoS requirements. At the same time, when the channel quality changes, the situation of data packet loss and retransmission also changes at any time. When the channel quality is very good, the reliability of lower-layer data transmission is high and the reordering requirement is low. At this time, the duration of the reordering timer can be shortened; when the channel quality is medium, the time for waiting for the lower layer to retransmit lost packets can be extended within a reasonable range; when the channel quality continues to deteriorate, it is very likely that waiting will not improve the retransmission success rate. At this time, the duration of the reordering timer may not be extended. In the embodiment of the present application, the service QoS parameters and the channel quality parameters are calculated by a weighted method to adaptively adjust the duration of the reordering timer.

[0140] It should be noted that, in the embodiment of the present application, the channel quality parameters and the service QoS parameters respectively refer to the current channel quality parameters and the current service quality of service QoS parameters. For example, the channel quality parameters and the service quality of service QoS parameters obtained when implementing the embodiment of the present application. Here, let the channel quality parameter be C, and the service QoS parameter be represented as Q.

[0141] This step may include the following process:

[0142] S1. Determine a first channel quality value based on the channel quality parameter.

[0143] Here, compare the channel quality parameter C with a first channel quality threshold (C1) and a second channel quality threshold (C2) respectively, where the first channel quality threshold is greater than the second channel quality threshold.

[0144] If the channel quality parameter is greater than or equal to the first channel quality threshold, the value of the first channel quality value is a first value; or, if the channel quality parameter is less than the first channel quality threshold and greater than the second channel quality threshold, the value of the first channel quality value is a second value; or, if the channel quality parameter is less than or equal to the second channel quality threshold, the value of the first channel quality value is a third value.

[0145] Among them, the first value, the second value and the third value can be set through Operations Maintenance (OM).

[0146] For example, when C≥C1, it means that the current channel quality is good; when C1>C>C2, it means that the current channel quality is medium; when C2≥C, it means that the current channel quality is poor. The channel quality thresholds C1 and C2 can be set through OM or directly use empirical values. For example, when the channel quality is higher than 10, the channel quality is better; when it is lower than 6, the channel quality is worse.

[0147] When the channel quality is good, the data transmission efficiency is high, and there is no need to wait for a long time for reordering and the data can be delivered to the upper layer as soon as possible. Therefore, the duration of the reordering timer can be reduced. Therefore, when C≥C1, the first channel quality value (i.e., the channel quality value of the reordering timer) c = -1; when the channel quality is medium, there may be a certain degree of retransmission, and the reliability of data transmission can be ensured by increasing the waiting duration of reordering. Therefore, when C1>C>C2, the first channel quality value (i.e., the channel quality value of the reordering timer) c = 1; when the channel quality is poor, there are a large number of retransmissions of data packets, and there may still be packet losses even after multiple retransmissions. A too long waiting duration for reordering will only increase the data transmission delay and will not bring obvious benefits to the on-demand delivery of data. Therefore, when C2≥C, the first channel quality value (i.e., the channel quality value of the reordering timer) c = -1.

[0148] S2. Determine a first service QoS requirement value according to the service QoS parameter.

[0149] Here, the service QoS parameter Q is compared with a first service QoS threshold (Q1) and a second service QoS threshold (Q2) respectively, where the first service QoS threshold is less than the second service QoS threshold;

[0150] If the service QoS parameter is less than or equal to the first service QoS threshold, the value of the first service QoS requirement is a fourth value; alternatively, if the service QoS parameter is greater than the first service QoS threshold and less than the second service QoS threshold, the value of the first service QoS requirement is a fifth value; or, if the service QoS parameter is greater than or equal to the second service QoS threshold, the value of the first service QoS requirement is a sixth value.

[0151] Among them, the fourth value, the fifth value and the sixth value can be set through OM.

[0152] For example, when Q ≤ Q1, it indicates that the current service QoS has a high requirement for real-time performance. When Q1 < Q < Q2, it means that the current service QoS has a medium requirement for real-time performance. When Q2 ≤ Q, it means that the current service QoS has a low requirement for real-time performance. The service QoS delay thresholds Q1 and Q2 can be set through OM.

[0153] When the service QoS has a high requirement for real-time performance, in order to meet the requirement of shorter delay, the duration of the reordering timer should be set as short as possible. Therefore, when Q ≤ Q1, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = -1; when the service QoS has a medium requirement for real-time performance, the duration of the reordering timer can remain unchanged. Therefore, when Q1 < Q < Q2, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = 0; when the service QoS has a low requirement for real-time performance, the allowed delay for data transmission may be longer, and the duration of the reordering timer can be appropriately increased. Therefore, when Q2 ≤ Q, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = 1.

[0154] S3. Determine the duration of the second reordering timer according to the first channel quality value and the first service QoS requirement value.

[0155] Here, determine the product of the first channel quality value and the first weight to obtain a first numerical value; determine the product of the first service QoS requirement value and the second weight to obtain a second numerical value; according to the first numerical value, the second numerical value, the retransmission timer adjustment step size and the current duration of the reordering timer, obtain the duration of the second reordering timer.

[0156] Among them, the weight c% of the first channel quality value and the weight q% of the first service QoS requirement value are set by the OM respectively, c% + q% = 100%, and the default value is 50% each.

[0157] For example, the duration of the second reordering timer can be obtained in the following manner:

[0158] Treordering = T + Δt × (c% × c + q% × q)

[0159] Among them, Treordering represents the duration of the second reordering timer, T represents the duration of the current reordering timer, Δt represents the retransmission timer adjustment step, c% × c is the first value, q% × q is the second value, c% represents the first weight, c represents the first channel quality value, q% represents the second weight, and q represents the first service QoS requirement value.

[0160] Among them, Δt is set by the OM, and the default value is 1 ms. The OM can configure Δt through the RRC message.

[0161] S4. Determine the duration of the first reordering timer according to the duration of the second reordering timer.

[0162] Here, if the duration of the second reordering timer is within the preset duration range of the reordering timer, use the second reordering timer as the duration of the first reordering timer. Among them, this duration range can be set as needed or set by the OM. If the duration of the second reordering timer is not within the preset duration range of the reordering timer, the reordering timer duration is not updated. Among them, this duration range can be determined according to the reasonable minimum and maximum values of the reordering timer, and these minimum and maximum values can be set as needed or set by the OM.

[0163] In practical applications, it can be determined whether to adjust the duration of the reordering timer at a certain period. For example, the adjustment period of the duration of the reordering timer is determined according to the service QoS parameter acquisition period and the channel quality parameter acquisition period, and the larger period between the two can be taken as the adjustment period of the duration of the reordering timer.

[0164] Step 103. Send the duration of the first reordering timer to the sending end.

[0165] Optionally, in this step, the receiving end can send the duration of the first reordering timer to the sending end in one or more of the following ways:

[0166] RRC message;

[0167] PDU.

[0168] In the embodiment of the present application, the receiving end determines the duration of the first reordering timer according to the channel quality parameter and the service QoS parameter, so that the duration of the reordering timer can be adapted to the channel quality parameter and the service QoS parameter, and the data transmission efficiency and accuracy of the user plane of the radio access network can be ensured.

[0169] See Figure 3 , Figure 3 which is a flowchart of the information processing method provided by the embodiment of the present application, applied to the sending end. As Figure 3 shown, it includes the following steps:

[0170] Step 301, receive the duration of the first reordering timer sent by the receiving end.

[0171] Wherein, the duration of the first reordering timer is determined by the receiving end according to the channel quality parameter and the service QoS parameter. The specific determination method can refer to the description of the foregoing method embodiment.

[0172] Step 302, adjust data transmission according to the duration of the first reordering timer.

[0173] Optionally, here, the sending end can adjust the data transmission volume and / or transmission priority according to the duration of the first reordering timer and the current channel quality. The current channel quality can be the channel quality when executing the embodiment of the present application.

[0174] For example, when the duration of the reordering timer becomes shorter and the channel quality is particularly good, it means that the data transmission efficiency is very good, and the data transmission volume can be increased; when the duration of the reordering timer becomes shorter but the channel quality is not good, it means that the transmission effect is poor and there are many packet losses, and the data transmission volume can be reduced; when the duration of the reordering timer becomes longer and the channel quality is good, it means that the QoS requirement of the transmitted data is not high, and the transmission priority of the transmitted data can be appropriately reduced; when the duration of the reordering timer becomes longer and the channel quality is medium, it means that the transmission efficiency is not high, and the data transmission volume can be appropriately reduced.

[0175] Among them, the determination of the above "particularly good", "not good", "good" and other standards can be set according to needs.

[0176] In the embodiment of the present application, the receiving end determines the duration of the first reordering timer according to the channel quality parameter and the service QoS parameter, so that the duration of the reordering timer can be adapted to the channel quality parameter and the service QoS parameter, and the data transmission efficiency and accuracy of the user plane of the radio access network can be ensured.

[0177] See Figure 4 , Figure 4 which is a flowchart of the information processing method provided by the embodiment of the present application, and may include:

[0178] Step 401: Obtain the channel quality parameter C, service QoS parameter Q, c%, and q%.

[0179] Step 402: Determine the duration of the second reordering timer.

[0180] When C ≥ C1, the first channel quality value (i.e., the channel quality value of the reordering timer) c = -1; when C1 > C > C2, the first channel quality value (i.e., the channel quality value of the reordering timer) c = 1; when C2 ≥ C, the first channel quality value (i.e., the channel quality value of the reordering timer) c = -1.

[0181] When Q ≤ Q1, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = -1; when Q1 < Q < Q2, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = 0; when Q2 ≤ Q, the first service QoS requirement value (i.e., the service QoS requirement value of the reordering timer) q = 1.

[0182] Obtain the duration of the second reordering timer in the following manner:

[0183] Treordering = T + Δt × (c% × c + q% × q)

[0184] where Treordering represents the duration of the second reordering timer, T represents the duration of the current reordering timer, Δt represents the retransmission timer adjustment step, c% × c is the first value, q% × q is the second value, c% represents the first weight, c represents the first channel quality value, q% represents the second weight, and q represents the first service QoS requirement value.

[0185] Step 403: Determine the duration of the first reordering timer.

[0186] Here, if the duration of the second reordering timer is within the preset duration range of the reordering timer (the range determined by the reasonable minimum and maximum values of the reordering timer duration, and the minimum or maximum value can be set as needed), use the second reordering timer as the duration of the first reordering timer. If the duration of the second reordering timer is not within the preset duration range of the reordering timer, do not update the reordering timer duration and end the process.

[0187] As can be seen from the above description, in the embodiments of this application, the reordering scheme can more accurately adapt to both higher-layer services and lower-layer channel quality, which can improve the data transmission efficiency and accuracy of the user plane in the radio access network. At the same time, the scheme of synchronizing the reordering timer at the sending end and the receiving end can achieve closed-loop self-adaptation of data transmission.
