[0215] To determine whether and how PDU Set processing can be applied in the uplink, the following issues must be addressed:

[0216] Question 1: When the first QoS flow has corresponding PDU Set parameters, the uplink may not require PDU Set QoS processing. For example, the terminal does not support PDU Set QoS, or the terminal application does not require PDU Set QoS processing. When PDU Set processing is not required, the uplink PDU Error Rate (PER) cannot be replaced by the PDU Set Error Rate (PSER), and the uplink PDU Delay Budget (PDB) cannot be replaced by the PDU Set Delay Budget (PSDB).

[0217] Solution 1: The core network (CN) needs to determine whether to apply PDU Set processing to the uplink based on the user equipment (UE)'s request or UE's capabilities. For example, if the UE does not support PDU Set processing or does not request it, the CN instructs the radio access network (RAN) not to apply PDU Set processing to the uplink.

[0218] Solution 2: The CN needs to determine whether to apply PDU Set processing to the uplink based on the request sent by the RAN. The RAN can initiate a request (such as the first request) to the CN based on the UE's request (such as the second request). The RAN determines whether to apply PDU Set processing to the uplink based on the CN's instruction.

[0219] Solution 3: The CN sends PDU Set parameters (including PDU Set QoS and PDU Set Importance) to the RAN. The RAN determines whether to apply PDU Set processing to the uplink based on the UE's capabilities or request.

[0220] Solution: The CN sends PDU Set parameters (including PDU Set QoS and PDU Set Importance) to the RAN. The RAN determines whether to apply PDU Set processing to the uplink based on the UE's capabilities or request.

[0221] Solution 4: The RAN decides whether to apply the PDU Set parameters based on the UE's indication of "whether it is feasible or infeasible to identify the PDU Set for the first QoS flow or the first radio bearer."

[0222] Solution 5: The SMF decides whether to configure PDU Set parameters for the uplink of the QoS flow based on whether identification of the PDU Set is feasible or infeasible for the first QoS flow. This information can be sent by the RAN or the UE.

[0223] Solution 6: The PCF determines whether to configure PDU Set parameters for the uplink QoS flow based on whether the PDU Set is feasible or infeasible for the first PCC rule or the first service flow. This "feasible or infeasible identification of the PDU Set for the QoS flow" can be sent by the RAN or the UE.

[0224] Issue 1.1: The CN may not have the PDU Set QoS parameters corresponding to the first QoS. This means the UE or RAN request will be rejected. To further improve efficiency, the UE or RAN can send the request if supported by the PDU Set.

[0225] For example, in Method 1, the CN sends information to the RAN indicating that the first QoS flow supports PDU Set processing. The UE sends a second request to the RAN requesting PDU Set processing for the first QoS flow or the first radio bearer. Based on the information sent by the CN indicating that the CN supports PDU Set processing, the RAN sends the first request to the CN requesting PDU Set processing.

[0226] For example, in mode 2, the CN sends a message to the UE indicating that the first QoS flow supports PDU Set processing. Based on the information sent by the CN indicating that the QoS flow supports PDU Set processing, the UE sends a first request to the CN for requesting PDU Set processing.

[0227] For example, in mode 3, the RAN sends a message to the UE indicating that the first QoS flow supports PDU Set processing. Based on the information sent by the RAN indicating that the RAN supports PDU Set processing, the UE sends a second request to the RAN for requesting PDU Set processing.

[0228] Question 2: When the UE requests PDU Set processing for the first QoS flow or the first radio bearer, the first QoS flow may not have corresponding PDU Set parameters (including at least one of the following: PDU Set QoS, the thirteenth information and PDU Set Importance). In this case, how to trigger the CN to configure the PDU Set parameters for the RAN needs to be solved. For example, a service only requires PDU Set processing for the uplink, but not for the downlink. Before the UE request or the RAN request, the CN does not need to send the corresponding PDU Set parameters to the RAN.

[0229] Solution 1: CN sends PDU Set parameters based on UE's request.

[0230] Solution 2: CN sends PDU Set parameters based on RAN's request. RAN's request can be based on UE's request.

[0231] Question 3: Packet loss based on PDU Set importance is a method of PDU Set processing, but it does not belong to PDU Set QoS. Currently, the control plane lacks an indication to inform the RAN whether packet loss processing should be performed based on PDU Set importance.

[0232] Solution: Inform the RAN on the control plane (CP) to process based on the importance of the PDU Set. For example, in the case of congestion, packet loss is based on the importance of the PDU Set.

[0233] Supplementary Note: This does not exclude scenarios where the UE also requests downlink PDU Set processing; the AF also requests uplink PDU Set processing; and the CN triggers bidirectional PDU Set QoS processing based on unidirectional PDU Set.

[0234] Question 4: When receiving the uplink PDU Set QoS for the first QoS flow, the RAN may not know whether it is feasible or not to identify the PDU Set for the first QoS flow or the first radio bearer, and it is also unclear whether to apply the uplink PDU Set QoS.

[0235] One solution is that when “for the first QoS flow or the first radio bearer, identification of whether the PDU Set is feasible or not is not requested”, the RAN does not apply the uplink PDU Set QoS.

[1355] Through the embodiments of the present application, it is clarified how the terminal, RAN, and core network cooperate to implement on-demand PDU Set processing, especially uplink PDU Set processing, and how the communication system as a whole performs PDU Set processing. This enables each communication device in the communication system to clearly define its own PDU Set processing method, cooperate with each other to complete PDU Set processing, solve PDU Set processing problems, and optimize the communication process.

[1356] The information processing method of the embodiment of the present application is described below in conjunction with specific application scenarios.

[1357] Example 1 of the present application

[1358] Referring to FIG6 , the first embodiment of the present application includes the following steps:

[1359] Step 1: The UE sends a first request to the SMF via the AMF (not shown). Optionally, the first request may be a first request corresponding to the first QoS flow.

[1360] Optionally, the first request may be included in a NAS message (such as a PDU session modification request) and sent.

[1361] The first request is used to request PDU Set processing (including requesting PDU Set processing for at least one of uplink and downlink).

[1362] The first request corresponding to the first QoS flow is used to request PDU Set processing for the first QoS flow (including requesting PDU Set processing for at least one of the uplink and downlink of the first object).

[1363] The PDU Set processing is as described in the first communication device embodiment and will not be repeated here.

[1364] Step 2: The SMF executes the first sub-operation of the third operation or the second sub-operation of the third operation according to the first request;

[1371] Sending a requested PDU Set QoS, the first request, at least one of the fifth information and the first capability information to the PCF.

[1372] The first PCC rule is a PCC rule flow bound to the first QoS flow.

[1373] In the embodiment shown in FIG6 , the SMF executes the second sub-operation of the third operation and sends the first request to the PCF.

[1374] In one implementation, the PDU Set QoS is used to implicitly indicate that PDU Set QoS is applied to the downlink, and a process based on the PDU Set QoS is applied to the downlink.

[1375] In one implementation, the application PDU Set importance implicitly indicates the importance of the downlink application PDU Set.

[1376] In one embodiment, the application is implicitly indicated by the processing based on the importance of the PDU Set: processing based on the importance of the PDU Set is applied to the downlink.

[1377] At this point, it is not difficult to understand that the third information may only indicate that PDU Set processing is applied to the uplink.

[1378] At this point, it is not difficult to understand that the fourth information may only indicate that the uplink supports PDU Set processing.

[1379] In one implementation, applying or not applying the PDU Set importance includes: applying or not applying the PDU Set importance to at least one of an uplink and a downlink.

[1380] In one implementation, applying or not applying the processing based on the importance of the PDU Set includes: applying or not applying the processing based on the importance of the PDU Set to at least one of an uplink and a downlink.

[1383] accept the first request or reject the first request;

[1384] Sending first information to the SMF, where the first information includes at least one of the following: PDU Set QoS, thirteenth information, third information, fourth information, and a first response;

[1385] The thirteenth information is used to indicate whether to apply or not apply the PDU Set importance, or to apply or not apply the processing based on the PDU Set importance;

[1386] The third information is used to indicate that PDU Set processing is applied to the uplink (when PDU Set QoS and the third information exist, the downlink indication is the default).

[1387] The fourth information is used to indicate support for uplink PDU Set processing.

[1388] The first response includes information for accepting or rejecting the first request.

[1389] Step 4: SMF sends the first information to RAN through AMF, where the first information includes at least one of the following: PDU Set QoS, thirteenth information, third information, fourth information, and first response.

[1390] Step 5: SMF sends a first response to the UE through AMF, where the first response includes information for accepting the first request.

[1391] In this embodiment, the sending order of steps 4 and 5 is not particular.

[1392] The first information and the first response may be included in the same NG interface message and sent.

[1397] The second request is used to request PDU Set processing (including requesting PDU Set processing for at least one of uplink and downlink).

[1398] The second request corresponding to the first object is used to perform PDU Set processing on the first object (including requesting to perform PDU Set processing on at least one of the uplink and downlink of the first object).

[1399] The PDU Set processing is as described in the first communication device embodiment and will not be repeated here.

[1400] Step 2: Based on the second request, the RAN sends a first request to the CN (e.g., to the SMF via the AMF). Optionally, the first request may be a first request corresponding to a first QoS flow. The first QoS flow is a QoS flow mapped to the first radio bearer.

[1401] Optionally, the first request may be sent to the SMF by a PDU session container included in an NG message (such as a PDU session modification request).

[1402] Optionally, when the third condition is met, the RAN sends a first request to the CN.

[1403] The third condition is as described in the second communication device embodiment and will not be repeated here.

[1404] Optionally, the first request sent by the RAN to the CN may be a first request corresponding to a first QoS flow. The first request corresponding to the first QoS flow is used to request PDU Set processing for the first QoS flow (including requesting PDU Set processing for at least one of an uplink and a downlink of the first QoS flow).

[1405] Optionally, when the twelfth condition is met, the RAN accepts the first request of the UE.

[1406] The twelfth condition is as described in the second communication device embodiment and will not be repeated here.
