[0024] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0025] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0026] In order to enable those skilled in the art to better understand the embodiments of the present application, first, the following description is given.

[0027] In related technologies, non-standalone (NSA) networking has developed rapidly to rapidly deploy 5G networks. NSA is a joint network of Long Term Evolution (LTE) and New Radio (NR). Early NSA networks were primarily based on LTE and 5G dual connectivity (E-UTRA-NR Dual Connectivity, EN-DC), with control plane data carried by LTE and user plane data partially or fully carried by NR. Typically, in Internet services, user plane data interaction far outweighs control plane data interaction.

[0028] When downlink split bear is used, on the network side, data packets from a Packet Data Convergence Protocol (PDCP) entity are numbered and split into an LTE Radio Link Control (RLC) entity and an NR RLC entity for transmission. On the terminal side, data packets received by the LTE RLC entity and the NR RLC entity are aggregated into the same NR PDCP entity. Data from a single PDCP entity is transmitted in parallel over both the LTE and NR paths.

[0029] The NR receiving PDCP entity has the following characteristics:

[0030] 1. Sliding Window-Based Receive Functionality: NR PDCP maintains a fixed-length sliding window. Whenever a new data packet is received whose count is greater than the count of any previously received packet, the sliding window is moved to a position where the upper limit equals the count of the packet (the lower limit of the sliding window is also updated accordingly). Subsequent received packets with counts below the lower limit of the sliding window are discarded.

[0031] 2. Reordering function: NR PDCP maintains a reordering timer with a fixed total duration. When a new data packet is received and the count value of the packet is discontinuous with the count value of the previous PDCP received packet, the packet is temporarily stored in the PDCP layer buffer and the reordering timer is started. Before the timer expires, the PDCP layer waits for the data packet before the packet to arrive at the PDCP layer. If the previous data packet is not received after the timeout, the waiting is stopped and the packet is taken out of the buffer and directly handed over to the upper layer.

[0032] When the data offload ratio on one path in NSA is too high, packet reception on the other path may be delayed. Data packets on both paths are assigned a unified count at the network-side PDCP layer, and on the terminal side, they are also aggregated and reordered based on the count at the PDCP layer. Therefore, in this scenario, the terminal PDCP layer will experience intermittent packet reception on the path with the higher offload ratio, while delayed packet reception on the path with the lower offload ratio. When the delay exceeds a certain threshold, these delayed packets are discarded. For example, if a terminal receives packets with counts 5944-5950 on the NR path but receives packets with counts 5903-5912 on the LTE path much later, the NR path packets will be delivered directly to the upper layer after the reordering timer expires, causing the receive window to shift backward. The subsequent packets received on the LTE path will fall outside the receive window and be discarded.

[0033] Since the PDCP layer does not have a HARQ / ARQ mechanism, even if the terminal side detects the above obvious packet reception intermittent / packet loss phenomenon at the PDCP layer, it cannot directly notify the network side to adjust the downlink transmission strategy.

[0034] The data processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] As shown in FIG1 , an embodiment of the present application provides a data processing method, which is executed by an electronic device, which may be specifically a terminal. The method includes:

[0036] Step 101: Obtain first status information of a first data packet received by the Packet Data Convergence Protocol (PDCP) layer, where the first status information includes first indication information and second indication information. The first indication information is used to indicate a transmission path of the first data packet in a non-standalone network (NSA), and the second indication information is used to indicate whether the first data packet is a reordering timed-out data packet.

[0037] Optionally, the first data packet is a data packet of an NSA service, and the first data packet includes W1 data packets, where W1 is a positive integer.

[0038] In the embodiment of the present application, the terminal records the first status information of each data packet received by the PDCP layer in real time. In order to save data storage, the W1 data packets are the W1 data packets most recently received by the PDCP layer of the terminal.

[0039] For example, the terminal may use a sliding recording window of fixed length to record the first status information of W1 data packets most recently received by the PDCP layer.

[0040] As an example, the above-mentioned first indication information may indicate that the transmission path of the data packet in the non-independent network NSA is an LTE path or an NR path.

[0041] Optionally, in the embodiment of the present application, whether the data packet is a reordering timed-out data packet may be determined in the following manner:

[0042] When a data packet is received and the count value of the packet is discontinuous with the count value of the previous data packet, the packet is temporarily stored in the PDCP layer buffer and the reordering timer is started. Before the timer times out, the process waits for the data packet before the packet to arrive at the PDCP layer. If the previous data packet is not received after the timeout, the process stops waiting, takes the data packet out of the buffer and directly hands it over to the upper layer, and determines the data packet as a reordering timed-out data packet.

[0043] Step 102: Determine whether there is a first transmission path in the transmission path according to the first status information of the first data packet, wherein a data packet with reordering timeout exists in the first data packets transmitted by the first transmission path.

[0044] Here, based on the above-mentioned first state information, it can be determined whether there are reordering timed-out packets in the transmission path of the NSA. If there are reordering timed-out packets in a certain transmission path, it can be determined that the numbering of packets in the transmission path is discontinuous due to the high diversion ratio, which may cause delays in the reception of packets in the path with a low diversion ratio. Therefore, it can be determined that the diversion strategy of the transmission path in the NSA is unreasonable.

[0045] Step 103: When it is determined that a first transmission path exists in the transmission path, the measured channel quality indicator (CQI) value is reduced and the reduced CQI value is reported. The CQI value is used to adjust the data packet transmission rate of the first transmission path.

[0046] Specifically, when it is determined that there is a first transmission path in the transmission path of the NSA, the terminal actively measures the current environment and signal, obtains the corresponding CQI value, and reduces the CQI value so that the network side device can reduce the data packet transmission rate of the above-mentioned first transmission path based on the reduced CQI value.

[0047] In an embodiment of the present application, the measured CQI value can be iteratively reduced or reduced by a preset step value, so that the network side can reduce the data packet transmission rate of the first transmission path based on the reduced CQI value, thereby reducing the number of data packets transmitted in the first transmission path, thereby achieving the purpose of limiting the flow of the first transmission path.

[0048] The above-mentioned scheme of the embodiment of the present application obtains the first status information of the first data packet received by the PDCP layer, and the first status information includes first indication information and second indication information. The first indication information is used to indicate the transmission path of the first data packet in the NSA, and the second indication information is used to indicate whether the first data packet is a data packet with reordering timeout; according to the first status information of the first data packet, it is determined whether there is a first transmission path in the transmission path of the NSA, wherein the first data packet transmitted by the first transmission path contains a data packet with reordering timeout; when it is determined that there is a first transmission path in the transmission path of the NSA, the measured channel quality indication CQI value is reduced, and the reduced CQI value is reported, and the CQI value is used to adjust the data packet transmission rate of the first transmission path, so that the network side can adjust the data packet transmission rate of the NSA transmission path based on the CQI, thereby achieving the purpose of notifying the network side to adjust the transmission path diversion strategy when the terminal detects that the downlink diversion strategy is unreasonable at the PDCP layer.

[0049] Optionally, when it is determined that the first transmission path exists in the transmission path of the NSA, reducing the measured channel quality indicator CQI value and reporting the reduced CQI value includes:

[0050] When it is determined that the first transmission path exists in the transmission path, obtaining second status information of a second data packet received by the PDCP layer through the second transmission path; wherein the second status information includes third indication information, and the third indication information is used to indicate whether the second data packet includes a data packet received outside a target time period;

[0051] When it is determined based on the second state information that the second data packet includes a data packet received outside the target time period, the measured channel quality indication CQI value is adjusted and the adjusted CQI value is reported, and the second transmission path is a transmission path different from the first transmission path.

[0052] Optionally, the second data packet includes W2 data packets, the second data packet is a data packet of the NSA service, and W2 is a positive integer.

[0053] As an implementation manner, the target time period is a time period corresponding to a receiving window of the second data packet.

[0054] Optionally, the second status information further includes a number, and the third indication information is used to indicate whether the second data packet corresponding to the number is included in the data packet received by the fingerprint in the target time period.

[0055] For example, if the first indication information of a data packet received by the PDCP layer indicates that the transmission path is the NR transmission path, and the second indication information of the data packet indicates that the data packet is a reordering timed-out data packet, then the above-mentioned NR transmission path is determined to be the above-mentioned first transmission path.

[0056] In the embodiment of the present application, when it is determined that the first transmission path exists in the transmission path of the NSA, W2 data packets are continuously received, and the second status information of the W2 data packets is recorded.

[0057] As an implementation, W2>W1. Specifically, the length of the sliding recording window is extended so as to record the second state information of the most recently received W2 data packets based on the extended sliding recording window.

[0058] The second status information is used to determine whether the second data packet transmitted by the second transmission path includes data packets received outside the target time period. If so, packet loss or a large accumulation of PDCP packets can be determined, further confirming that the traffic diversion strategy for the transmission path in NSA is unreasonable. The traffic diversion rate for the transmission path where the reordering timed out packets occurred is too high, necessitating traffic limiting for the transmission path where the reordering timed out packets occurred.

[0059] In an embodiment of the present application, after receiving the CQI value reported by the terminal, the network-side device adjusts the transmission rate of the transmission path of the NSA service currently registered by the terminal within a target time period (for example, within time period t). Within the target time period, the terminal detects in real time the packet loss rate of the data packets received by the PDCP layer per unit time or the number of data packets cached in the PDCP layer, so as to determine the CQI value at which the packet loss rate or the number of data packets cached in the PDCP layer meets a preset threshold as the target CQI value corresponding to the first transmission path, and then subsequently based on the target CQI value, it can be ensured that the packet loss rate or the number of data packets cached in the PDCP layer of the first transmission path meets the preset threshold.

[0060] As an optional implementation manner, after reducing the measured channel quality indicator CQI value and reporting the reduced CQI value, the method further includes:

[0061] detecting target parameters of data packets received by the PDCP layer within a target time period, the target parameters including a packet loss rate or a number of data packets buffered in the PDCP layer;

[0062] When the target parameter is less than a preset threshold, determine the reduced CQI value as the target CQI value corresponding to the target transmission path; or, when the target parameter is greater than or equal to the preset threshold, reduce the CQI value and report the reduced CQI value until the target parameter of the data packet received by the PDCP layer within the target time period is less than the preset threshold, and determine the CQI value corresponding to the target parameter less than the preset threshold as the target CQI value corresponding to the target transmission path;

[0063] The target CQI value is used to determine the data packet transmission rate of the first transmission path.

[0064] In this implementation, the CQI value at which the packet loss rate or the number of cached data packets in the PDCP layer is less than a preset threshold is determined as the target CQI value corresponding to the first transmission path. Subsequently, based on the target CQI value, it can be ensured that the packet loss rate or the number of cached data packets in the PDCP layer of the first transmission path is less than the preset threshold, thereby avoiding the problem of PDCP layer data packet disorder and packet loss caused by unreasonable NSA downlink diversion strategy.

[0065] Optionally, the method of the embodiment of the present application further includes:

[0066] Report the target CQI value corresponding to the first transmission path.

[0067] In an embodiment of the present application, after determining the above-mentioned target CQI value, an association relationship between the first transmission path and the target CQI value is established. After establishing the association relationship between the first transmission path and the target CQI value, when the UE terminal performs NSA service again in the same cell environment, it will preferentially report the target CQI value corresponding to the first transmission path to the network in order to obtain a better or suitable diversion rate, thereby helping to improve the network rate and reduce the network packet loss rate.

[0068] Through the solution of the embodiment of the present application, the problem of PDCP layer packet loss on the terminal side caused by unreasonable downlink diversion strategy on the network side under NSA can be effectively improved, and the packet loss rate can be reduced and the Internet access speed can be improved.

[0069] The data processing method provided in the embodiment of the present application can be executed by a data processing device. In the embodiment of the present application, the data processing device provided in the embodiment of the present application is described by taking the data processing method executed by the data processing device as an example.
