[0036] The embodiments of the present disclosure provide a data processing method, user equipment, network equipment, and a communication system.

[0037] In a first aspect, an embodiment of the present disclosure provides a data processing method, applied to a user equipment (UE), the method comprising:

[0038] The MAC entity of the UE obtains trigger parameters of the upper layer PDU; wherein the trigger parameters include: a PSI value of the PDU and / or a remaining time until the data packet is discarded, or a configuration parameter of a discard timer of the PDU and / or a remaining time until the data packet is discarded;

[0039] Determine whether to trigger DSR according to the trigger parameter.

[0040] In the above embodiment, the UE determines whether to trigger DSR based on the trigger parameters; for the case where the PDU Set is relatively less important or the discard timer has a shorter timing period, the DSR is not triggered in the embodiment of the present disclosure, thereby reducing invalid DSR and avoiding invalid DSR occupying wireless resources and aggravating the degree of congestion.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, determining whether to trigger DSR according to the trigger parameter includes at least one of the following:

[0042] Determining whether to trigger DSR based on whether the PSI value of the PDU belongs to a preset PSI set and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold;

[0043] Determining whether to trigger DSR based on whether the PSI value of the PDU is greater than a preset first PSI threshold and / or whether the remaining time before the data packet is discarded is greater than a preset discard time threshold;

[0044] Whether to trigger DSR is determined according to whether the type of the discard timer of the PDU is a target type, and / or whether the remaining time before the data packet is discarded is greater than a preset discard time threshold.

[0045] In the above embodiment, if the PSI value of the PDU belongs to a preset PSI set, the relative importance of the PDU Set to which the PDU belongs in the QoS flow is higher, otherwise it is lower. If the PSI value of the PDU is not greater than the preset first PSI threshold, the relative importance of the PDU Set to which the PDU belongs in the QoS flow is higher, otherwise it is lower. The target type is, for example, a timer with a shorter timing time. Due to the shorter timing time, such a timer will be more likely to time out (expiry) and be discarded. In this way, according to the trigger parameter, it is determined whether to trigger the DSR. For the case where the PDU Set has a relatively low relative importance or the discard timer has a short timing time, the DSR is not triggered in the embodiment of the present disclosure, thereby reducing invalid DSRs and avoiding invalid DSRs occupying wireless resources and increasing the degree of congestion.

[0046] In combination with some embodiments of the first aspect, in some embodiments, determining whether to trigger DSR based on whether the PSI value of the PDU is greater than a preset first PSI threshold and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold includes at least one of the following:

[0047] The PSI value of the PDU belongs to a preset PSI set, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold, determining to trigger DSR;

[0048] The PSI value of the PDU does not belong to the preset PSI set, and it is determined that the DSR is not triggered.

[0049] In the above embodiment, the PSI value of the PDU belongs to a preset PSI set, the PDU Set to which the PDU belongs is relatively important in the QoS flow, and the remaining time before the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, at which point it is necessary to trigger DSR. The PSI value of the PDU does not belong to the preset PSI set, and the PDU Set to which the PDU belongs is relatively less important in the QoS flow. PDU Sets of relatively less importance are more likely to be discarded during congestion, so there is no need to trigger DSR. This reduces invalid DSRs and avoids invalid DSRs occupying wireless resources and aggravating congestion.

[0050] In combination with some embodiments of the first aspect, in some embodiments, determining whether to trigger DSR based on whether the PSI value of the PDU is greater than a preset first PSI threshold and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold includes at least one of the following:

[0051] The PSI value of the PDU is not greater than a preset first PSI threshold, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold, determining to trigger DSR;

[0052] The PSI value of the PDU is greater than a preset first PSI threshold, and it is determined that DSR is not triggered.

[0053] In the above embodiment, if the PSI value of the PDU is not greater than the preset first PSI threshold, the relative importance of the PDU Set to which the PDU belongs is relatively high, and the remaining time before the data packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the data packet is discarded, and it is necessary to trigger DSR at this time; if the PSI value of the PDU is greater than the preset first PSI threshold, the relative importance of the PDU Set to which the PDU belongs in the QoS flow is relatively low, and the PDU Set with relatively low importance is more likely to be discarded during congestion. At this time, there is no need to trigger DSR, thereby reducing invalid DSRs and avoiding invalid DSRs occupying wireless resources and aggravating the degree of congestion.

[0054] In combination with some embodiments of the first aspect, in some embodiments, determining whether to trigger DSR based on whether the type of the discard timer of the PDU is a target type and / or whether the remaining time before the data packet is discarded is greater than a preset discard time threshold includes:

[0055] The configuration parameters of the discard timer of the PDU indicate that the type of the discard timer is not a target type, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold, determining to trigger DSR;

[0056] The configuration parameter of the discard timer of the PDU indicates that the type of the discard timer is a target type, and it is determined that DSR is not triggered.

[0057] In the above embodiment, the PDU's discard timer is not a target type, that is, it is not the aforementioned timer with a shorter timer, and the remaining time before the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, in which case it is necessary to trigger a DSR. The PDU's discard timer is the aforementioned timer with a shorter timer. Due to the shorter timer, such a timer is more likely to time out (expiry) and be discarded. In this case, there is no need to trigger a DSR, thereby reducing invalid DSRs and avoiding invalid DSRs occupying radio resources and aggravating congestion.

[0058] In conjunction with some embodiments of the first aspect, in some embodiments, the preset PSI set is pre-set or obtained from a first signaling of a network device;

[0059] The first signaling includes at least one of the following:

[0060] Radio Resource Control (RRC) signaling, Packet Data Convergence Protocol (PDCP) Control (PDU) signaling, and MAC Control Element (MAC) signaling.

[0061] In combination with some embodiments of the first aspect, in some embodiments, the first signaling includes the RRC signaling, and the preset PSI set and the first PSI threshold include at least one of the following:

[0062] Configuring the MAC entity;

[0063] Configuration for PDCP entities;

[0064] Configured in the logical channel group LCG configuration information;

[0065] Configured in the QoS flow configuration information.

[0066] In combination with some embodiments of the first aspect, in some embodiments, the first PSI threshold multiplexes the second PSI threshold when the UE discards a data packet.

[0067] In the above embodiment, the first PSI threshold can also be associated with the second PSI threshold used when the PSI packet is discarded, and the second PSI threshold when the UE discards the data packet is multiplexed, that is, the first PSI threshold and the second PSI threshold are set to the same value; in this way, when the PSI value of the PDU is greater than the preset first PSI threshold, the PDU will be discarded, so the DSR is not triggered for the PDU.

[0068] In combination with some embodiments of the first aspect, in some embodiments, the target type includes: a timer with a shorter timing time among the discard timers of the PDCP entity of the UE.

[0069] In the above embodiment, the discard timer of the PDU is a timer with a relatively short timing time among the discard timers of the PDCP entity of the UE. Due to the short timing time, such a timer is more likely to time out (expiry) and thus be discarded.

[0070] In a second aspect, an embodiment of the present disclosure provides a data processing method, which is applied to a network device. The method includes:

[0071] receiving a DSR sent by a user equipment UE;

[0072] The DSR obtains the trigger parameters of the upper-layer PDU for the MAC entity of the UE and is triggered according to the trigger parameters; the trigger parameters include: the PSI value of the PDU and / or the remaining time before the data packet is discarded, or the configuration parameters of the discard timer of the PDU and / or the remaining time before the data packet is discarded.

[0073] In the above embodiment, the MAC entity of the UE obtains the trigger parameters of the upper-layer PDU, for example, the PSI value of the PDU and / or the remaining time before the data packet is discarded, or the configuration parameters of the discard timer of the PDU and / or the remaining time before the data packet is discarded; and triggers the DSR according to the trigger parameters. The network device receives the DSR sent by the user equipment UE, and can obtain the delay status of relatively important data in the UL (uplink) data (that is, the remaining time before the data packet is discarded).

[0074] In conjunction with some embodiments of the second aspect, in some embodiments, the PSI value of the PDU belongs to a preset PSI set, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold;

[0075] The PSI value of the PDU is not greater than a preset first PSI threshold, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold;

[0076] or

[0077] The configuration parameter of the discard timer of the PDU indicates that the type of the discard timer is not a target type.

[0078] In the above embodiment, if the PSI value of the PDU belongs to a preset PSI set, the PDU Set to which the PDU belongs is relatively important in the QoS flow, and the remaining time until the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, and it is necessary to trigger DSR at this time; if the PSI value of the PDU is not greater than the preset first PSI threshold, the PDU Set to which the PDU belongs is relatively important, and the remaining time until the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, and it is necessary to trigger DSR at this time; if the discard timer of the PDU is not a target type, that is, it is not the aforementioned timer with a shorter timing time, and the remaining time until the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, it is necessary to trigger DSR at this time.

[0079] In a third aspect, an embodiment of the present disclosure further provides a user device, which includes at least one of an acquisition module and a determination module; wherein the user device is used to execute the optional implementation method of the first aspect.

[0080] In a fourth aspect, an embodiment of the present disclosure further provides a network device, comprising: a receiving module; wherein the above-mentioned network device is used to execute the optional implementation method of the second aspect.

[0088] In an eighth aspect, an embodiment of the present disclosure further provides a storage medium storing instructions, which, when executed on a communication device, enables the communication device to execute the optional implementation methods described in the first and second aspects.

[0120] FIG2 is an interactive diagram of a data processing method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0121] In step 201, the MAC entity of the user equipment UE101 obtains the trigger parameters of the upper layer PDU; wherein, the trigger parameters include: the PDU set importance PSI value of the PDU and / or the remaining time before the data packet is discarded, or the configuration parameters of the discard timer of the PDU and / or the remaining time before the data packet is discarded.

[0122] In a mobile communication system, the Media Access Control (MAC) entity is a MAC layer functional module operating at Layer 2 (data link layer L2). The MAC entity provides services to its higher layers, such as the Radio Link Control (RLC) layer, via logical channels.

[0123] To prevent transmit buffer congestion, the Packet Data Convergence Protocol (PDCP) layer defines a packet discard mechanism. In this mechanism, when a transmitting PDCP entity receives a PDCP Service Data Unit (SDU) from a higher layer, it starts a corresponding discard timer for that PDCP SDU. If the discard timer for a PDCP SDU expires, the transmitting PDCP entity discards the PDCP SDU and the corresponding PDCP Data Protocol Data Unit (PDU).

[0124] In the embodiment of the present disclosure, the MAC entity obtains the trigger parameters of the upper layer PDU; the PDU sent by the upper layer is such as RLC PDU or PDCP PDU. The trigger parameters of PDU can include two cases: case 1 and case 2; specifically,

[0125] Case 1: the PDU set importance (PSI) value of the PDU and / or the remaining time until the data packet is discarded;

[0126] The PDU Set Importance (PSI) parameter indicates the relative importance of a PDU Set relative to other PDU Sets in the same Quality of Service (QoS) flow. Generally, a larger PSI value indicates a lower PDU Set importance, and a smaller PSI value indicates a higher PDU Set importance. For example, a PSI value of 0 indicates the highest importance PDU Set, and a PSI value of 15 indicates the lowest importance PDU Set. In the event of congestion, the PSI can be used to determine whether the PDU Set should be discarded. For example, the UE can discard data packets with lower importance indicated by the PSI value when congested.

[0127] The remaining time until the data packet is discarded is the time until the PDCP entity or the RLC entity discards the PDU; wherein the remaining time until the data packet is discarded can be determined according to the remaining time of the discard timer.

[0128] Case 2: configuration parameters of the PDU discard timer and / or the remaining time before the data packet is discarded.

[0129] The configuration parameter of the discard timer is used to indicate whether the type of the discard timer is a target timer; optionally, the type of the target timer is, for example, a timer with a shorter timing time among the discard timers of the PDCP entity of the UE.

[0130] Step 202: Determine whether to trigger a Delay Status Report (DSR) based on the triggering parameters. If it is determined that the DSR is to be triggered, execute step 206.

[0131] UE 101 determines, based on the trigger parameters, whether the MAC entity triggers a Delay Status Report (DSR). In a mobile communication system, when some data packets have not been scheduled for a long time, the UE may send a DSR to notify the network. For example, the UE sends the DSR via the MAC entity, such as by carrying it in a MAC Control Element (MAC CE). If the remaining time before the data packet is discarded is less than a threshold configured by the network, a DSR report may be triggered.

[0132] Optionally, the DSR includes information about the remaining time and the corresponding data volume; the granularity of the DSR report is the Logical Channel Group (LCG).

[0133] In the embodiment of the present disclosure, whether to trigger DSR is determined based on the trigger parameters; for situations where DSR does not need to be triggered, DSR is not triggered in the embodiment of the present disclosure. For example, the PSI value of the PDU indicates that the PDU Set to which the PDU belongs is relatively less important (for example, the PSI value is larger). In the QoS flow, the PDU Set of relatively less important is more likely to be discarded during congestion; or, the discard timer of the PDU is the aforementioned timer with a shorter timing time. Due to the shorter timing time, such a timer is more likely to time out (expiry) and thus be discarded. On the one hand, in the case of congestion, if the PDU Set of these PDUs still triggers DSR, the DSR has no meaning to be reported, and the network side is likely to not allocate resources for the PDU Set of relatively less important. On the other hand, such an invalid DSR occupies wireless resources and will aggravate the degree of congestion. Therefore, in the embodiment of the present disclosure, whether to trigger the delay status report DSR is determined based on the trigger parameters. For the case where the PDU Set is relatively less important or the timing time of the discard timer is short, the DSR is not triggered in the embodiment of the present disclosure, thereby reducing invalid DSRs and avoiding invalid DSRs occupying wireless resources and aggravating the degree of congestion.

[0134] In some embodiments, as shown in FIG2 , step 202 includes at least one of step 203 , step 204 , and step 205 .

[0135] Step 203: Determine whether to trigger DSR based on whether the PSI value of the PDU belongs to a preset PSI set and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold.

[0136] Among them, the conditions for the MAC entity to trigger DSR include not only whether the remaining time before the PDU packet is discarded is less than the discard time threshold configured by the network, but also when the PDU belongs to a PDU Set and has a corresponding PSI value, the PSI needs to meet certain conditions, that is, the PSI belongs to a specific set.

[0137] Among them, the PSI value in the preset PSI set may include a value of relatively high importance of the PDU Set, for example, the preset PSI set is PSI{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}; if the PSI value of the PDU belongs to the preset PSI set, the PDU Set to which the PDU belongs in the QoS flow has a higher relative importance, otherwise it is lower.

[0138] In some embodiments, as shown in FIG. 2 , step 203 further includes step 2031 and step 2032 .

[0139] In step 2031 , the PSI value of the PDU belongs to a preset PSI set, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold, and a DSR is determined to be triggered; subsequently, step 206 is executed.

[0140] Among them, the PSI value of the PDU belongs to a preset PSI set, the PDU Set to which the PDU belongs has a high relative importance in the QoS flow, and the remaining time before the packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the packet is discarded, and it is necessary to trigger DSR at this time.

[0141] Step 2032: The PSI value of the PDU does not belong to the preset PSI set, and it is determined that DSR is not triggered.

[0142] Among them, the PSI value of the PDU does not belong to the preset PSI set, and the PDU Set to which the PDU belongs has a relatively low importance in the QoS flow. The PDU Set with relatively low importance is more likely to be discarded during congestion. At this time, there is no need to trigger DSR, reduce invalid DSR, and avoid invalid DSR occupying wireless resources and aggravating the degree of congestion.

[0143] Step 204: Determine whether to trigger DSR based on whether the PSI value of the PDU is greater than a preset first PSI threshold and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold.

[0144] The first PSI threshold may be a preset value. For example, if the PSI value is greater than the preset first PSI threshold, the corresponding PDU Set has a lower relative importance in the QoS flow. For example, the first PSI threshold is set to 13. If the PSI value of the PDU is not greater than the preset first PSI threshold, the PDU Set to which the PDU belongs has a higher relative importance in the QoS flow; otherwise, it has a lower relative importance.

[0145] In some embodiments, as shown in FIG. 2 , step 204 further includes step 2041 and step 2042 .

[0146] Step 2041: If the PSI value of the PDU is not greater than a preset first PSI threshold, and the remaining time until the data packet is discarded is not greater than a preset discard time threshold, it is determined that DSR is triggered; then step 206 is executed.

[0147] Among them, the PSI value of the PDU is not greater than the preset first PSI threshold, the PDU Set to which the PDU belongs is relatively important in the QoS flow, and the remaining time before the data packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the data packet is discarded, and it is necessary to trigger DSR at this time.

[0148] Step 2042: The PSI value of the PDU is greater than a preset first PSI threshold, and it is determined that DSR is not triggered.

[0149] Among them, the PSI value of the PDU is greater than the preset first PSI threshold, and the PDU Set to which the PDU belongs has a relatively low importance in the QoS flow. The PDU Set with relatively low importance is more likely to be discarded during congestion. At this time, there is no need to trigger DSR, reduce invalid DSR, and avoid invalid DSR occupying wireless resources and aggravating the degree of congestion.

[0150] In some embodiments, the first PSI threshold multiplexes the second PSI threshold when the UE discards a data packet.

[0151] The first PSI threshold may also be associated with the second threshold used when a PSI packet is discarded, and the second PSI threshold used when the UE discards a data packet may be reused. That is, the first PSI threshold is not configured separately and has the same value as the second PSI threshold, for example, 13. In this way, when the PSI value of the PDU is greater than the preset first PSI threshold, the PDU is discarded, and thus a DSR is not triggered for the PDU.

[0152] Step 205: Determine whether to trigger DSR based on whether the type of the discard timer of the PDU is a target type and / or whether the remaining time until the data packet is discarded is greater than a preset discard time threshold.

[0153] The MAC entity triggers DSR based on whether the remaining time until the PDU is discarded is less than the discard time threshold configured by the network. It also includes whether the PDU's discard timer is of a target type. For example, a target type timer with a short timer is more likely to expire and be discarded due to its short timer.

[0154] In some embodiments, as shown in FIG. 2 , step 205 further includes step 2051 and step 2052 .

[0155] Step 2051: The configuration parameters of the discard timer of the PDU indicate that the type of the discard timer is not the target type, and the remaining time until the data packet is discarded is not greater than the preset discard time threshold, and it is determined that DSR is triggered; then step 206 is executed.

[0156] The discard timer of the PDU is not a target type, that is, it is not the aforementioned timer with a shorter timing time, and the remaining time before the data packet is discarded is not greater than the preset discard time threshold, that is, there is still some time before the data packet is discarded, and it is necessary to trigger DSR at this time.

[0157] Step 2052: The configuration parameters of the discard timer of the PDU indicate that the type of the discard timer is a target type, and it is determined not to trigger DSR.

[0158] The discard timer of the PDU is the aforementioned timer with a shorter timing time. Due to the shorter timing time, such a timer will be more likely to time out (expiry) and be discarded. At this time, there is no need to trigger DSR, reduce invalid DSR, and avoid invalid DSR occupying wireless resources and aggravating the degree of congestion.

[0159] Optionally, taking the first PSI threshold set to 13 as an example, the DSR triggering condition may be: when the remaining time of a PDU in an LCG (if configured for DSR) becomes shorter than its associated remaining time threshold, and if the PDU belongs to a PDU set, the PSI of the PDU is less than or equal to 13, the MAC entity triggers a DSR (The MAC entity triggers a DSR when: the remaining time of a PDU in an LCG, if configured for DSR, becomes shorter than its associated remainingTimeThreshold, and the PSI of the PDU is less than or equal to 13, if the PDU belongs to a PDU set).

[0160] In some embodiments, the preset PSI set is pre-set or obtained from a first signaling of a network device;

[0161] The first signaling includes at least one of the following:

[0162] Radio Resource Control (RRC) signaling, Packet Data Convergence Protocol (PDCP) Control (PDU) signaling, and MAC Control Element (MAC) signaling.

[0163] Among them, the preset PSI set is pre-set, such as specified by the protocol; the preset PSI set can also be obtained from the first signaling of the network device, and the first signaling includes at least one of RRC signaling, PDCP Control PDU signaling and MAC CE signaling (such as signaling including MAC CE).

[0164] In some embodiments, the first signaling includes the RRC signaling, and the preset PSI set and the first PSI threshold include at least one of the following:

[0165] The preset PSI set is configured for the MAC entity;

[0166] The preset PSI set is configured for the PDCP entity;

[0167] The preset PSI set is configured in the logical channel group LCG configuration information;

[0168] The preset PSI set is configured in the quality of service QoS flow configuration information.

[0169] Among them, when RRC signaling is used for configuration, the two parameters of the preset PSI set and the first PSI threshold can be configured in the MAC entity, for example, in the IE MAC-CellGroupConfig. Specifically, for example, the following configuration is added in the RRC signaling: "psi DSR threshold: the threshold on PSI value for triggering DSR for an LCG"; and the following configuration is added to the MAC entity DSR triggering condition: "If the PDU belongs to a PDU set, the PSI of the PDU is less than or equal to the PSI DSR threshold (the PSI of the PDU is less than or equal to psi-DSR-Threshold, if the PDU belongs to a PDU set)", where the PSI DSR threshold is the first PSI threshold.

[0170] It can also be configured in the PDCP entity, for example, in PDCP (ie, in IE PDCP-Config); it can also be LCG configuration, configured in the logical channel group LCG configuration information; or it can be QoS flow configuration, configured in the QoS flow configuration information.

[0171] In some embodiments, the target type includes: a timer with a shorter timing time among the discard timers of the PDCP entity of the UE.

[0172] The discard timer of the PDU is a timer with a relatively short timing time among the discard timers of the PDCP entity of the UE. Due to the short timing time, such a timer is more likely to time out (expiry) and thus be discarded.

[0173] Optionally, as an example, the shorter discard timer used by the less important PDU Set in the PSI packet discard scheme is called the congestion discard timer. Then RRC controls the DSR operation by configuring the following parameters:

[0174] remainingTimeThreshold: The threshold on remaining time of UL data configured for triggering DSR for an LCG; The MAC entity triggers a DSR when the remaining time of a PDU in an LCG, if configured for DSR, becomes shorter than its associated remainingTimeThreshold, and the discard timer associated with the PDU is not congestionDiscard Timer.

[0175] Step 206, UE 101 sends a DSR to network device 102;

[0176] At the same time, the network device 102 receives the DSR sent by the user equipment UE101.

[0177] Optionally, when UE 101 determines not to trigger a Delay Status Report DSR, the network device 102 does not receive the DSR.

[0178] In this way, for the case where the PDU Set is relatively less important or the discard timer is shorter, the DSR is not triggered in the embodiment of the present disclosure, thereby reducing invalid DSRs and avoiding invalid DSRs occupying wireless resources and increasing the degree of congestion.

[0219] As shown in FIG4 , the above method may be applied to a network device 102, and the above method includes:

[0220] Step 401: When UE 101 determines to trigger a Delay Status Report (DSR), the network device 102 receives the DSR sent by the user equipment UE.
