[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0054] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0055] Figure 1 is a flow chart of a method for determining configuration parameters according to an exemplary embodiment. In some embodiments, the method may be applied to a terminal; in some embodiments, the method may be applied to a modem, exemplarily, a modem of a mobile terminal; Figure 1 As shown, the method includes the following steps.

[0056] Step S110: In response to data from an application process (AP), a first delay type corresponding to the data is determined.

[0057] The first delay type corresponding to the data is related to the data service to which the data belongs; in some embodiments, the first delay type is related to the delay requirement of the data service.

[0058] In some embodiments, the first delay type may be one of the following: a high delay type, a medium delay type and a low delay type, wherein the high delay type corresponds to data services with low delay requirements, such as web pages and short videos, the medium delay type corresponds to data services with moderate delay requirements, such as live broadcasts, and the low delay type corresponds to data services with high delay requirements, such as games; or, in some embodiments, the first delay type is delay-sensitive or non-delay-sensitive, which correspond to delay-sensitive services and non-delay-sensitive services, respectively.

[0059] Step S120: Determine a first configuration parameter of a packet data convergence protocol layer entity according to the network state parameter and the first delay type.

[0060] The network status parameter is a buffer status report (Buffer Status Report, BSR) parameter or a signal strength parameter.

[0061] Among them, the cache status report is used to apply for uplink resources from the network side and notify the network side of the amount of resources required to transmit the data in the uplink buffer. The value of the cache status report parameter reflects the amount of data in the uplink buffer currently to be transmitted, and the value of the cache status report parameter is positively correlated with the amount of data in the uplink buffer currently to be transmitted.

[0062] In some embodiments, the signal strength parameter may be any one of the following parameters: Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Receiving Quality (RSRQ), and Signal to Interference plus Noise Ratio (SINR), etc.

[0063] The packet data convergence protocol layer is located above the radio link control protocol (Radio Link Control, RLC) sublayer and is responsible for processing the service data of the packet service, such as IP data stream. The packet data convergence protocol layer provides services to the upper layer of the radio resource control protocol (Radio Resource Control, RRC) and the user plane on the terminal side, or to the relay on the base station side, including the transmission of user plane data and the transmission of control plane data; at the same time, the packet data convergence protocol layer can provide services to the lower layer, including: transparent data transmission services, confirmed data transmission services (including indications of successful transmission of protocol data units) and unconfirmed data transmission services (sequential transmission, packet duplication or discard processing), etc.

[0064] In some embodiments, the packet data convergence protocol layer entity includes: at least one of a discard timer (DiscardTimer) and a reordering timer (t-Reordering, also known as t-Reordering Timer). It can be understood that if the packet data convergence protocol layer entity includes a discard timer and a reordering timer, the first configuration parameter is a set of parameters, including a discard timer configuration parameter and a reordering timer configuration parameter.

[0065] Among them, the discard timer is a timer for the Data Radio Bearer (DRB). On the sending side of the packet data convergence protocol layer, a discard timer is started for each service data unit (SDU). After the discard timer times out, the service data unit is discarded to prevent sending buffer congestion; the reordering timer is on the receiving side of the packet data convergence protocol layer. A receiving side entity can only start one reordering timer, which is used to detect packet loss continuously based on whether the sequence number is continuous. After the reordering timer times out, it is similar to the timeout of the reassembly timer in the unreliable (UnacknowledgedMode, UM) mode of the radio link control protocol. The receiving side submits the result to the upper layer, but does not require the other end to retransmit.

[0066] Step S130: Determine the target configuration parameter according to the first configuration parameter and the second configuration parameter of the packet data convergence protocol layer entity that is pre-delivered by the network side.

[0067] The target configuration parameter is determined according to the first configuration parameter determined by the terminal side and the second configuration parameter sent by the network side.

[0068] In some embodiments, the network side sends the second configuration parameter via a radio resource control protocol reconfiguration message.

[0069] In some embodiments, in step S130, after determining the target configuration parameter according to the first configuration parameter and the second configuration parameter of the packet data convergence protocol layer entity pre-issued by the network side, the method further includes: configuring the packet data convergence protocol layer entity according to the target configuration parameter.

[0070] In the related art, the network side sends down configuration parameters to configure the packet data aggregation protocol layer entity to control data transmission. However, the method for determining the configuration parameters on the network side is relatively simple and cannot be dynamically adjusted according to the actual data transmission situation. For example, when configuring the discard timer, the network side generally configures the discard timer to be infinite. This method will make the discard timer unable to control the uplink data delay. For data services with high delay requirements, it will be very easy to experience freezes and an unsmooth data experience.

[0071] The present disclosure provides a configuration parameter determination method, the method comprising: determining a first delay type corresponding to the data in response to data from an application side; determining a first configuration parameter of a packet data convergence protocol layer entity according to a network state parameter and the first delay type, wherein the network state parameter is a cache state report parameter or a signal strength parameter; determining a target configuration parameter according to the first configuration parameter and a second configuration parameter of the packet data convergence protocol layer entity pre-issued by the network side. Thus, compared with the solution in the related art that only relies on the configuration parameter pre-issued by the network side, the solution of the embodiment of the present disclosure determines the first configuration parameter of the packet data convergence protocol layer entity according to the network state parameter and the first delay type, and determines the target configuration parameter according to the determined first configuration parameter and the second configuration parameter issued by the network side, comprehensively considering the actual network state and the delay requirements of the data service when determining the configuration parameter of the packet data convergence protocol layer entity, improving the flexibility of data transmission control, and ensuring the quality of communication services. Moreover, corresponding to the case where the packet data convergence protocol layer entity includes a discard timer and a reordering timer, the solution of the embodiment of the present disclosure can realize targeted flow control and effective reordering of different data services.

[0072] Figure 2 is a flow chart of another configuration parameter determination method according to an exemplary embodiment. In some embodiments, the method can be applied to a terminal; in some embodiments, the method can be applied to a modem, exemplarily, a modem of a mobile terminal; Figure 2 As shown, the method includes the following steps.

[0073] Step S200: Classify data services according to their delay requirements to obtain multiple second delay types.

[0074] The second delay type corresponds to different delay requirements.

[0075] In some embodiments, the second delay type includes a high delay type, a medium delay type, and a low delay type; or, in some embodiments, the second delay type includes a delay sensitive type and a non-delay sensitive type.

[0076] Step S211: Determine a first delay type from multiple second delay types according to the delay type identifier carried in the data.

[0077] Among them, the delay type identifier is configured by the application side after determining the corresponding second delay type according to the data service to which the data belongs; in some embodiments, the value of the delay type identifier corresponds to a second delay type respectively; in some embodiments, the delay type identifier can be embodied as an identifier, a label, a flag bit, etc.

[0078] Step S220: Determine a first configuration parameter of a packet data convergence protocol layer entity according to the network state parameter and the first delay type.

[0079] Step S230: Determine the target configuration parameter according to the first configuration parameter and the second configuration parameter of the packet data convergence protocol layer entity that is pre-delivered by the network side.

[0080] Therefore, multiple second delay types are set according to different delay requirements of data services, the first configuration parameters are determined according to the first delay type determined therefrom, and the target configuration parameters are determined according to the first configuration parameters and the second configuration parameters. The determined target configuration parameters can meet the delay requirements of the current data services.

[0081] Figure 3 FIG. 1 is a flow chart of an implementation method of step S120 in the embodiment of the present disclosure. Figure 3 As shown, step S120, determining a first configuration parameter of a packet data convergence protocol layer entity according to a network state parameter and a first delay type, includes:

[0082] Step S121: In response to a value of a network status parameter being greater than or equal to a first preset threshold, determining one of a plurality of preset third configuration parameters as a first configuration parameter according to a first delay type.

[0083] Step S122: In response to the value of the network status parameter being less than a first preset threshold, determining one of a plurality of preset fourth configuration parameters as a first configuration parameter according to the first delay type.

[0084] Among them, segmented settings are pre-set according to network status parameters, each third configuration parameter corresponds to a second delay type, and each fourth configuration parameter corresponds to a second delay type. Therefore, according to the value of the network status parameter and the first delay type, the first configuration parameter can be selected from the preset third configuration parameter or the preset fourth configuration parameter.

[0085] Figure 4 is a flow chart of another method for determining configuration parameters according to an exemplary embodiment. In some embodiments, the method may be applied to a terminal; in some embodiments, the method may be applied to a modem, exemplarily, a modem of a mobile terminal; Figure 4 As shown, the method includes the following steps.

[0086] Step S310: In response to data from the application side, determine a first delay type corresponding to the data.

[0087] Step S323: Determine a first configuration parameter according to the network state parameter, the first delay type, and the currently used radio access technology (Radio Access Technology, RAT).

[0088] Exemplarily, the wireless access technology may include access technology of the 3rd Generation Partnership Project (3GPP), such as Long Term Evolution (LTE), Standalone (SA) and New Radio (NR).

[0089] Step S330: Determine the target configuration parameter according to the first configuration parameter and the second configuration parameter of the packet data convergence protocol layer entity that is pre-delivered by the network side.

[0090] Figure 5 FIG. 4 is a flow chart of an implementation method of step S323 in the embodiment of the present disclosure. Figure 5 As shown, step S323, determining the first configuration parameter according to the network state parameter, the first delay type and the currently used wireless access technology, includes:

[0091] Step S3231: In response to the value of the network status parameter being greater than or equal to a second preset threshold, one of a plurality of preset fifth configuration parameters is determined as a first configuration parameter according to a first delay type and a wireless access technology.

[0092] Step S3232: In response to the value of the network status parameter being less than a second preset threshold, one of a plurality of preset sixth configuration parameters is determined as a first configuration parameter according to the first delay type and the wireless access technology.

[0093] Among them, for each wireless access technology, segment settings are pre-set according to the network status parameters, each fifth configuration parameter corresponds to a second delay type, and each sixth configuration parameter corresponds to a second delay type. Therefore, according to the value of the network status parameter, the first delay type and the wireless access technology currently used, the first configuration parameter can be selected from the preset fifth configuration parameter or the preset sixth configuration parameter.

[0094] Figure 6 FIG. 1 is a flow chart of an implementation method of step S130 in the embodiment of the present disclosure. Figure 6 As shown, step S130, determining the target configuration parameter according to the first configuration parameter and the second configuration parameter of the packet data convergence protocol layer entity pre-delivered by the network side, includes:

[0095] Step S131: Calculate a parameter difference according to the second configuration parameter and the first configuration parameter.

[0096] In some embodiments, the difference between the value of the second configuration parameter and the value of the first configuration parameter is calculated to obtain the parameter difference value; or, in some embodiments, the absolute value of the difference between the value of the second configuration parameter and the value of the first configuration parameter is calculated to obtain the parameter difference value.

[0097] In some embodiments, the packet data convergence protocol layer entity includes a discard timer and a reordering timer. Correspondingly, the first configuration parameter is a set of parameters, including a discard timer configuration parameter and a reordering timer configuration parameter, and the parameter difference includes the difference corresponding to the discard timer configuration parameter and the difference corresponding to the reordering timer configuration parameter.

[0098] Step S132: In response to the parameter difference being less than or equal to the preset difference, determining the second configuration parameter as the target configuration parameter.

[0099] Step S133: In response to the parameter difference being greater than the preset difference, determining the first configuration parameter as the target configuration parameter.

[0100] In some embodiments, the corresponding parameter differences include differences corresponding to discard timer configuration parameters and differences corresponding to reordering timer configuration parameters, and the size relationship between each difference and a preset difference is determined respectively, and the target configuration parameters are determined accordingly.

[0101] Therefore, when the second configuration parameter sent by the network side can meet the current network status and the delay requirements of the current data service, the second configuration parameter is determined as the target configuration parameter; when the second configuration parameter cannot meet the current network status and the delay requirements of the current data service, the first configuration parameter determined by the terminal side is determined as the target configuration parameter.

[0102] The configuration parameter determination method provided by the present disclosure is described below in combination with practical applications.

[0103] Figure 7 FIG. 1 is a schematic diagram showing a communication scenario according to an exemplary embodiment. Figure 7 As shown, the terminal establishes a communication connection with the base station on the network side, wherein the terminal initiates network registration to the base station after being powered on, and the base station sends the second configuration parameter of the packet data convergence protocol layer entity through a radio resource control protocol reconfiguration message. In some embodiments, the terminal is a multi-card multi-standby terminal; in some embodiments, the terminal is a terminal that supports multiple wireless access technologies.

[0104] Figure 8 FIG. 1 is a flow chart of another method for determining configuration parameters according to an exemplary embodiment. Figure 8 As shown, this method can be applied to Figure 7The terminal in the illustrated scenario, in particular, the method can be applied to a modem of the terminal, the terminal supports multiple wireless access technologies, and the method includes the following steps.

[0105] Step S400: Classify data services according to their delay requirements to obtain multiple second delay types.

[0106] Among them, the second delay type includes a high delay type, a medium delay type and a low delay type.

[0107] Step S401: Establish multiple arrays according to supported wireless access technologies and second delay types.

[0108] Among them, a single array records configuration parameters corresponding to a second delay type under a wireless access technology.

[0109] In some embodiments, after the terminal is powered on, multiple arrays are established according to the supported wireless access technologies and the second delay type.

[0110] Exemplarily, corresponding to the wireless access technology being long term evolution, the array corresponding to the fifth configuration parameter includes: a first high delay type configuration array, a first medium delay type configuration array, and a first low delay type configuration array; wherein the first high delay type configuration array is recorded as HighDelayConfigiration1{PDCP discardTimer=300ms, t-reordering timer=200ms}, the first medium delay type configuration array is recorded as MiddleDelayConfigiration1{PDCPdiscardTimer=1000ms, t-reordering timer=300ms}, and the first low delay type configuration array is LowDelayConfigiration1{PDCP discardTimer=infinity, t-reordering timer=300ms}. The array corresponding to the sixth configuration parameter includes: a second high delay type configuration array, a second medium delay type configuration array, and a second low delay type configuration array; among them, the second high delay type configuration array is recorded as HighDelayConfigiration2{PDCP discardTimer=500ms, t-reordering timer=200ms}, the second medium delay type configuration array is recorded as MiddleDelayConfigiration2{PDCP discardTimer=2000ms, t-reordering timer=300ms}, and the second low delay type configuration array is recorded as LowDelayConfigiration2{PDCP discardTimer=infinity, t-reordering timer=300ms}.

[0111] Step S410: In response to data from the application side, determine a first delay type from multiple second delay types according to a delay type identifier carried in the data.

[0112] Among them, the delay type identifier is configured by the application side after determining the corresponding second delay type according to the data service to which the data belongs. The delay type identifier is in the form of a flag bit, and its three values ​​correspond to one of the high delay type, medium delay type and low delay type respectively.

[0113] Among them, the first delay type corresponding to the data is determined according to the delay type identifier to be one of a high delay type, a medium delay type and a low delay type.

[0114] Step S420: Determine a first configuration parameter of a packet data convergence protocol layer entity according to a network state parameter, a first delay type, and a currently used wireless access technology.

[0115] Among them, the network status parameter is a cache status report parameter.

[0116] In which, in response to the value of the network status parameter being greater than or equal to the second preset threshold, one of the multiple fifth configuration parameters is determined as the first configuration parameter according to the first delay type and the wireless access technology; in response to the value of the network status parameter being less than the second preset threshold, one of the multiple sixth configuration parameters is determined as the first configuration parameter according to the first delay type and the wireless access technology.

[0117] For example, if the value of the network status parameter is greater than the second preset threshold, the first delay type is a high delay type, and the wireless access technology is long term evolution, then the fifth configuration parameter corresponding to the first high delay type configuration array is determined to be the first configuration parameter, and the first high delay type configuration array is read to obtain the first configuration parameter, that is, the discard timer configuration parameter is 300ms, and the reordering timer configuration parameter is 200ms.

[0118] Step S430: Calculate a parameter difference according to the second configuration parameter of the packet data convergence protocol layer entity and the first configuration parameter that are pre-delivered by the network side.

[0119] For the first configuration parameter and the second configuration parameter, the difference between the discard timer configuration parameter and the reordering timer configuration parameter is calculated respectively to obtain the parameter difference.

[0120] Step S431: determine whether the parameter difference is less than or equal to the preset difference.

[0121] The preset difference is 100ms.

[0122] It is determined whether the difference values ​​corresponding to the discard timer configuration parameter and the reordering timer configuration parameter are both less than or equal to the preset difference value. If so, execute step S432; if not, execute step S433.

[0123] Step S432: determine the second configuration parameter as the target configuration parameter.

[0124] Step S433: determine the first configuration parameter as the target configuration parameter.

[0125] Step S440: configure the packet data convergence protocol layer entity according to the target configuration parameters.

[0126] Wherein, the discard timer and the reordering timer are configured according to the target configuration parameters.

[0127] Therefore, the configuration parameters of the packet data convergence protocol layer entity are determined in the above manner, and the configuration is completed accordingly.
