[0057] The communication method, apparatus, communication device, and readable storage medium provided by the embodiments of the present disclosure are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0058] Please refer to FIG2 , which is a flowchart of a communication method provided by an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG2 , the method includes the following steps:

[0059] Step 21: The terminal reports first information, where the first information is used to indicate the terminal's ability to support uplink PDU set processing.

[0060] Since the terminal is the core of uplink PDU set handling, the processing of uplink PDU sets between the terminal and the base station depends largely on the terminal implementation. Therefore, based on the terminal's reported ability to support uplink PDU set processing, the network side can generate a corresponding network policy for uplink PDU set processing, that is, generate QoS information for the uplink PDU set, thereby supporting the terminal to provide QoS guarantee for the uplink PDU set and realize QoS processing of the uplink PDU set.

[0061] The capability of the terminal to support uplink PDU set processing may be understood as a property that the terminal supports uplink PDU set processing.

[0062] Optionally, the first information may explicitly or implicitly indicate that the terminal supports the capability of uplink PDU set processing. When explicitly indicating that the terminal supports the capability of uplink PDU set processing, the first information may be a newly added field or may reuse an existing field.

[0063] Optionally, the first information may be sent via a Session Management (SM) message in a PDU session establishment process or a PDU session update process. For example, the first information may be a newly added field in the SM message or an existing field in a multiplexed SM message.

[0064] Optionally, in addition to indicating the terminal's support for uplink PDU set processing capabilities, the first information may also indicate which specific PDU set handling capabilities the terminal supports. For example, the first information may indicate that the terminal supports PDU set importance, i.e., supports determining the priority of data transmission based on PDU set importance; and / or indicates that the terminal supports PDU set integrated handling indication (PSIHI), i.e., supports determining whether to perform integrity protection on or discard data packets based on the indication of PSIHI.

[0065] Optionally, the terminal has the capability to identify a specific QoS flow and can perform uplink PDU set handling for the specific QoS flow.

[0066] Optionally, after the terminal reports its capability of supporting uplink PDU set processing, the communication method in this embodiment may further include:

[0067] The terminal receives the QoS information of the uplink PDU set sent by the first network function, or receives the QoS information of the uplink PDU set sent by the first network function through the base station;

[0068] The terminal performs processing of the uplink PDU set.

[0069] It is understandable that when the terminal performs processing of the uplink PDU set, it can be performed based on the QoS information of the received uplink PDU set. The execution of processing of the uplink PDU set based on the QoS information of the received uplink PDU set can be understood as: the execution of processing of the uplink PDU set is related to the QoS information of the uplink PDU set, or the execution of processing of the uplink PDU set is performed with reference to the QoS information of the uplink PDU set.

[0070] Optionally, the first network function includes but is not limited to AMF, SMF, etc. The QoS information may be generated by a second network function (such as PCF) and sent to the first network function.

[0071] The QoS information includes QoS parameters, such as 5QI, PDU set importance (PDU set importance), PDU set error rate (PDU Set Error Rate, PSER), PDU set delay budget (PDU Set Delay Budget, PSDB), etc.

[0072] Thus, the terminal can implement QoS processing of the uplink PDU set based on the received QoS information of the uplink PDU set.

[0073] Optionally, the terminal may obtain QoS parameters (parameters) of the uplink PDU set and instruction information for performing uplink (UL) PDU set handling on a specific 5-tuple from the core network through a NAS message.

[0074] Optionally, the processing of the uplink PDU set includes but is not limited to at least one of the following: 1) the terminal maps a specific uplink QoS flow to a data radio bearer (DRB) that performs PDU set handling according to the description of the 5QI and the non-access stratum (NAS) indication of the core network; 2) the terminal determines the priority of data transmission or identifies which messages need to be discarded based on the PDU set importance; 3) the terminal determines whether to perform integrity protection or discard the data message based on the indication of the PDU set comprehensive processing indication PSIHI; 4) the terminal identifies which messages need to be quickly scheduled based on the received PSDB; and so on.

[0075] Optionally, the communication method in this embodiment may further include:

[0076] The terminal sends a first request to the first network function via a NAS message, wherein the first request is used to request QoS information of the PDU set. Thus, the terminal can request to obtain QoS information of the uplink PDU set.

[0077] For example, the terminal may send the first request to the first network function through a NAS message before receiving the QoS information of the uplink PDU set sent by the first network function, or before receiving the QoS information of the uplink PDU set sent by the first network function through the base station. Thereafter, the first network function may forward the first request to a second network function (such as a PCF) for assisting in generating a network policy for uplink and / or downlink PDU set processing.

[0078] In the disclosed embodiments, a terminal needs to identify which messages belong to a PDU set based on protocol description information in order to process the uplink PDU set. The protocol description information can be obtained directly from the application layer, service layer, etc., or from the core network, such as through NAS messages.

[0079] Optionally, the communication method in this embodiment may further include at least one of the following:

[0080] (1) The terminal performs processing of the uplink PDU set based on the QoS information of the uplink PDU set. The processing of the uplink PDU set based on the QoS information of the uplink PDU set can be understood as: performing processing of the uplink PDU set in relation to the QoS information of the uplink PDU set, or performing processing of the uplink PDU set with reference to the QoS information of the uplink PDU set.

[0081] (2) The terminal performs processing of the uplink PDU set based on the QoS information and protocol description information of the uplink PDU set;

[0082] (3) The terminal performs processing of the uplink PDU set based on the protocol description information.

[0083] The above (1) can be understood as follows: the terminal performs processing of the uplink PDU set based solely on the QoS information of the uplink PDU set. The protocol description information in (2) and (3) above can be obtained by the terminal from at least one of the following: the terminal itself, the service layer, the application layer, or the upper layer. Combining the protocol description information can help identify the protocol type and service characteristics, thereby selecting the appropriate QoS guarantee to perform processing of the uplink PDU set.

[0084] Based on the above (1) to (3), it can be concluded that the terminal can perform processing of the uplink PDU set based on at least one of the acquired protocol description information and the QoS information of the uplink PDU set.

[0085] For example, as shown in Figure 3, when the terminal UE obtains the QoS parameters of the uplink PDU set from the radio access network (Radio Access Network, RAN), it can also obtain protocol description information (Protocol Description) from the terminal upper layer or application layer to combine the QoS parameters and protocol description information of the PDU set to perform QoS processing of the uplink PDU set.

[0086] Please refer to Figure 4, which is a flow chart of a communication method provided by an embodiment of the present disclosure. The method is applied to a second network function, which can be a PCF or other network function with a policy control function. As shown in Figure 4, the method includes the following steps:

[0087] Step 41: The second network function generates a network policy for uplink and / or downlink PDU set processing based on the local configuration and / or the capability of supporting uplink PDU set processing reported by the terminal;

[0088] Step 42: The second network function sends a network policy for uplink and / or downlink PDU set processing.

[0089] Optionally, the network policy for processing uplink and / or downlink PDU sets can be understood as QoS information (such as QoS parameters) of the uplink and / or downlink PDU sets. The network policy for processing uplink and / or downlink PDU sets includes which flow to perform QoS processing on.

[0090] Optionally, step 42 may include at least one of the following:

[0091] 1) The second network function sends the network policy for uplink PDU set processing to the terminal through the first network function;

[0092] 2) The second network function sends the network policy for uplink PDU set processing to the base station through the first network function, and the base station forwards the network policy for uplink PDU set processing to the terminal.

[0093] Optionally, the first network function includes but is not limited to AMF, SMF, etc.

[0094] Thus, the terminal can implement QoS processing of the uplink PDU set according to the received network policy for processing the uplink PDU set, that is, the QoS information of the uplink PDU set.

[0095] Optionally, when the second network function (such as PCF) / first network function (such as AMF / SMF) learns that the terminal performs UL PDU set handling, it can send the QoS parameters of the UL PDU set to the terminal through a NAS message.

[0096] Optionally, the communication method in this embodiment may further include:

[0097] The second network function receives the second information sent by the third network function, or receives the second information sent by the third network function through the network exposure function NEF; the second information includes but is not limited to at least one of the following:

[0098] The first indication information is used to instruct to perform PDU set processing on uplink and / or downlink;

[0099] Flow description information; for example, the flow description information is QoS flow description information;

[0100] Protocol description information.

[0101] In this way, after receiving the second information, the second network function (such as PCF) can be assisted to generate a network policy for uplink and / or downlink PDU set processing.

[0102] Optionally, the third network function may be an application function AF.

[0103] Optionally, the communication method in this embodiment may further include:

[0104] The second network function receives a first request sent by the terminal through the first network function, where the first request is used to assist the second network function in generating a network policy for uplink and / or downlink PDU set processing.

[0105] Please refer to Figure 5, which is a flow chart of a communication method provided by an embodiment of the present disclosure. The method is applied to a third network function, which can be an AF or other network function with application functions. As shown in Figure 5, the method includes the following steps:

[0106] Step 51: The third network function sends second information to the second network function.

[0107] In this embodiment, the second network function may be a PCF or other network function with a policy control function. The second information includes but is not limited to at least one of the following:

[0108] The first indication information is used to instruct to perform PDU set processing on uplink and / or downlink;

[0109] Flow description information; for example, the flow description information is QoS flow description information;

[0110] Protocol description information.

[0111] In this way, the second network function (such as PCF) can be assisted to generate a network policy for uplink and / or downlink PDU set processing, and then the network policy for uplink PDU set processing can be sent to the terminal, so that the terminal can implement QoS processing of the uplink PDU set.

[0112] Optionally, the third network function (such as AF) may send the second information to the second network function (such as PCF) through the network opening function NEF.

[0113] Please refer to FIG6 , which is a flowchart of a communication method provided by an embodiment of the present disclosure. The method is applied to a base station. As shown in FIG6 , the method includes the following steps:

[0114] Step 61: The base station receives QoS information of the uplink PDU set sent by the second network function;

[0115] Step 62: The base station sends the QoS information of the uplink PDU set to the terminal.

[0116] In this way, the terminal can implement QoS processing of the uplink PDU set according to the received QoS information of the uplink PDU set.

[0117] Optionally, the second network function may be a PCF or other network function with a policy control function, which is not limited.

[0118] Optionally, the QoS information includes QoS parameters, such as 5QI, PDU set error rate PSER, PDU set delay budget PSDB, etc.

[0119] For example, a base station (such as the Next Generation Radio Access Network (NG-RAN)) can obtain the QoS information of the uplink PDU set from the core network during the PDU session establishment or modification process and forward it to the terminal, thereby supporting the terminal to provide specific QoS guarantees for the uplink PDU set.

[0120] The present disclosure is described below with reference to specific embodiments.

[0121] Example 1

[0122] In this embodiment 1, the UL PDU set processing capability is negotiated during the PDU session establishment or modification process. As shown in FIG7 , the specific process includes:

[0123] Step 1. The AF (or through the NEF) sends second information to the PCF. The second information includes at least one of the following: first indication information for instructing to perform PDU set handling for uplink and / or downlink; flow description information; and protocol description information. That is, the AF instructs to perform PDU set handling for UL / DL and provides flow description and / or protocol description.

[0124] Step 2: During the PDU session establishment or PDU session update process, the UE reports to the AMF its ability to support UL PDU set handling, which can be carried in the 5G SM capability, for example.

[0125] Step 3. Optionally, AMF reports UE capabilities to PCF via SMF.

[0126] Step 4: The PCF generates a corresponding network policy for uplink and / or downlink PDU set processing based on the information received from the AF, local configuration and / or UE capabilities, that is, generates QoS information (such as QoS parameters) for the uplink and / or downlink PDU set.

[0127] Step 5: The PCF sends the QoS information of the uplink PDU set to the UE through the AMF and SMF, so that the UE performs QoS processing of the uplink PDU set based on the received QoS information.

[0128] Example 2

[0129] In this embodiment 2, the UL PDU set processing capability is negotiated during the PDU session establishment or modification process, and QoS information is sent down through the base station. As shown in Figure 8, the specific process includes:

[0130] Steps 1-4 are the same as steps 1-4 in the above embodiment 1.

[0131] Step 5: PCF sends the QoS information of the uplink PDU set to the base station through AMF and SMF.

[0132] Step 6: The UE obtains protocol description information (Protocol Description) and / or QoS information of the uplink PDU set from the base station, so as to perform QoS processing of the uplink PDU set.
