[0102] In one embodiment of this application, the card may include one of the following: a Subscriber Identity Module (SIM card), a Universal Subscriber Identity Module (USIM card), or an Embedded Subscriber Identity Module (eSIM card).

[0103] In one embodiment of this application, the terminal may include at least one of the following: a relay supporting terminal functions and a terminal supporting relay functions. The terminal may also be referred to as a terminal device or user equipment (UE). The terminal may be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device, etc. It should be noted that the specific type of terminal is not limited in the embodiments of this application.

[0104] In this application embodiment, the following problems need to be solved:

[0105] Question 1: After introducing the ratio of PDUs in the PDU Set, it is unclear what information the RAN will respond with, and it is also unclear how the CN will activate the PDU Session Anchor (PSA) UPF to perform PDU Set information identification and PDU Set information marking.

[0106] Question 1.1: PDU Set processing in related technologies relies on the PSA UPF to identify the PDU Set to which a data packet belongs and to mark the PDU Set in the packet header. However, the aforementioned PDU Set information identification and marking depend on the RAN providing instructions to support PDU Set processing. However, in related technologies, instructions to support PDU Set processing are only sent when the RAN receives at least one of the following: PDU Set Delay Budget (PSDB), PDU Set Error Rate (PSER), and PDU Set Integrated Handling Information (PSIHI).

[0107] To address the aforementioned issues, in one embodiment of this application, the CN sends a first ratio to the RAN. If the RAN supports PDU Set processing, the RAN responds with a first indication message, which indicates one of the following: PDU Set processing is supported, or the RAN supports PDU Set processing.

[0108] Question 1.2: Packet loss handling based on the proportion of PDUs in a PDU set requires new RAN capabilities. For example, the PDU set handling supported by the R18 RAN may differ from that supported by the R19 RAN.

[0109] R18's RAN support for PDU Set processing does not include support for processing based on the first ratio.

[0110] R19's RAN-supported PDU Set processing may or may not include processing based on a first ratio.

[0111] Therefore, in another implementation, the CN sends a first ratio to the RAN, and if the RAN supports processing based on the first ratio, the RAN responds with a second indication message, the second indication message indicating one of the following: processing based on the first ratio is supported, or the RAN supports processing based on the first ratio.

[0112] The second instruction information differs from the first instruction information, which can resolve backward compatibility issues. For example, the R18 RAN may ignore the first ratio if it does not recognize it. The R19 RAN, which supports the first ratio, receives and recognizes the first ratio and can return either the first instruction information or the second instruction information.

[0113] From the CN's perspective, the second indication information can be used to identify that the RAN supports the first ratio.

[0114] Question 1.3: In related technologies, a successful PDU set is defined as 100% of the PDUs in the set being successful (e.g., successful PDU set transmission). After introducing this ratio, it's unclear whether the definition of a successful or failed PDU set needs to be reconsidered.

[0115] In one implementation, a PDU set only needs 80% of its components to be decoded. Therefore, it can be considered that the PDU set is successful if only 80% of the PDUs in the PDU set are decoded. If more than or equal to 20% of the PDUs fail to be transmitted or are discarded, the PDU set is considered to have failed to be transmitted.

[0116] Question 2: If PDU Set QoS is not currently available, and PDU Set information identification and / or PDU Set information marking are supported, then an indication message can be sent to the RAN to indicate that PDU Set information identification and / or PDU Set information marking are supported.

[0117] If the first ratio exists, or if the RAN is required to perform processing based on the first ratio, the aforementioned indication information may not need to be sent to the RAN. Therefore, it implicitly indicates support for PDU Set information identification and / or PDU Set information marking.

[0118] Therefore, in one implementation, if PDU Set QoS is absent, or if the first ratio is unclear, then if PDU Set information identification and PDU Set information marking are supported, then indication information indicating that PDU Set information identification and / or PDU Set information marking are supported can be sent to the RAN.

[0119] In one embodiment of this application, the ratio can be understood as a proportion.

[0120] In one embodiment of this application, applying PDU Set importance includes at least one of the following: applying PDU Set importance to uplink and applying PDU Set importance to downlink.

[0121] In one embodiment of this application, not applying PDU Set importance includes at least one of the following: not applying PDU Set importance for uplink and not applying PDU Set importance for downlink.

[0127] In one embodiment of this application, the aforementioned uplink and downlink directions are described from the perspective of the terminal. The data received by the terminal can be understood as downlink data, and the data sent by the terminal can be understood as uplink data.

[0130] In one embodiment of this application, uplink PDU Set processing can be understood as PDU Set processing in the uplink direction.

[0131] In one embodiment of this application, downlink PDU Set processing can be understood as PDU Set processing in the downlink direction. The application of downlink PDU Set processing can be understood as the application of PDU Set QoS processing in the downlink direction (e.g., applying PDU Set QoS processing to downlink data).

[0132] In one embodiment of this application, the PDU Set QoS processing is the PDU Set QoS processing of a first object.

[0160] In one embodiment of this application, the PDU Set size refers to the size of the PDU Set, such as the amount of data, which can be measured in bytes, bits, or the number of data packets.

[0161] In one embodiment of this application, PDU Set end indication information is used to indicate whether the data packet carrying the PDU Set end indication information is or is not the end data packet or the last data packet of the PDU Set. The PDU Set end indication information can be reflected by an indication or can be reflected by encoding together with other information.

[0162] In one embodiment of this application, PDU Set start indication information is used to indicate whether a data packet carrying the PDU Set start indication information is or is not the start data packet or the first data packet of the PDU Set. The PDU Set start indication information can be embodied by a single indication or encoded together with other information.

[0164] In one embodiment of this application, the sequence number of the PDU Set may be 1, 2, or 3, for example, there may be multiple PDU Sets, namely PDU Set 1, PDU Set 2, and PDU Set 3.

[0165] In one embodiment of this application, the duration of the PDU Set can be one of the following: the interval between the reception time of the last received data packet of the PDU Set and the reception time of the first received data packet, or the interval between the transmission time of the last transmitted data packet of the PDU Set and the transmission time of the first transmitted data packet.

[0180] Processing based on the importance of PDU Sets

[0181] Apply the first ratio;

[0182] Processing based on the first ratio.

[0183] In one implementation, requesting PDU Set processing includes requesting PDU Set processing for uplink and / or downlink.

[0184] In one implementation, the first request or the second request corresponding to the first object is used to request PDU Set processing to be applied to the first object (including requesting PDU Set processing for the uplink and / or downlink of the first object).

[0185] In one implementation, the Protocol Description (PD) information is used for one of the following:

[0186] Describes the usage protocol of the data stream;

[0187] Used to identify the PDU Set to which a data packet belongs (e.g., information in the protocol header of the protocol description information can be used to identify the PDU Set to which the data packet belongs).

[0188] Used to mark PDU Set information;

[0189] Used to identify data bursts (for example, information in the protocol header of the protocol description information can be used to identify the PDU Set information to which the data packet belongs);

[0190] Used to mark data burst information.

[0191] In one implementation, the protocol description information is the protocol description information corresponding to the first QoS flow.

[0199] Optionally, protocol description information: indicates the service data stream (such as RTP, SRTP) and the transport protocol used for the information, such as the following:

[0189] and RTP payload formats such as H.264

[0187] or H.265

[0188] .

[0207] Alternatively, by combining the protocol description information option of SRTP with the RTP payload format, the UPF can still obtain some PDU set information from the RTP header.

[0208] When including RTP header extensions for PDU set marking (as defined in TS26.522

[0179] ) or other RTP header extensions as described in RFC 8285

[0189] , the distinction between different RTP header extension types should be supported.

[0209] When including RTP payload formats, the differences between different RTP payload formats should be supported.

[0210] Optionally, the current version does not support multiplexing of different transport protocols and different media traffic to achieve processing based on differentiated PDU sets.

[0211] In one implementation, the protocol description information can be one of the following:

[0212] Protocol description information used only in the uplink direction;

[0233] The following description, in conjunction with the accompanying drawings, details the method, apparatus, communication device, and readable storage medium for PDU Set processing provided in this application, through some embodiments and application scenarios.

[0234] Please refer to Figure 2, which is a flowchart of a PDU Set processing method provided in an embodiment of this application. The method applies a first communication device, which includes an access network device (including the access network device (RAN device) accessed by the terminal or after handover). The method includes the following steps:

[0238] Based on the first rate of packet loss;

[0239] The first condition includes receiving first information, which includes at least one of the following: a first ratio and third indication information, wherein the third indication information is information for requesting the execution of processing based on the first ratio;

[0240] The first indication information is used to indicate one of the following: PDU Set processing is supported, or the first communication device supports PDU Set processing;

[0241] The second indication information is used to indicate one of the following: processing based on the first ratio is supported, or the first communication device supports processing based on the first ratio.

[0242] In one embodiment, the first communication device is an access network device, such as a RAN network element accessed by the terminal, or a target RAN network element after handover.

[0243] In one embodiment, the first communication device sends the first indication information or the second indication information to the second communication device.

[0244] In one embodiment, the first communication device receives the first information sent by the second communication device.

[0245] In one embodiment, the second communication device is a core network device, such as an SMF (Software-Defined Network).

[0246] In one embodiment, the first communication device receives a third indication message sent by the second communication device, the third indication message being information requesting the execution of processing based on the first ratio. Alternatively, the first communication device receives a first ratio sent by the second communication device; receiving the first ratio indicates that it is being requested to execute processing based on the first ratio.

[0248] The success or failure of the PDU Set is determined based on the first ratio;

[0249] Packet loss based on the first ratio.

[0250] In one implementation, PDU Set processing is supported to include one of the following:

[0251] Both the network (such as at least one of a wireless access network and a core network) and the terminal support PDU Set processing;

[0252] The network (such as at least one of the wireless access network and the core network) supports PDU Set processing.

[0255] The network (such as at least one of a radio access network and a core network) supports processing based on the first ratio.

[0256] In one implementation, the first ratio may also be referred to as the PDU Set related ratio.

[0257] In one implementation, since the first ratio is a PDU Set related ratio, processing based on the first ratio can be understood as PDU Set processing based on the first ratio, that is, processing based on the first ratio also belongs to PDU Set processing.

[0268] In one embodiment, when the first condition is met, first indication information is sent; the first condition further includes at least one of the following: the first communication device supports PDU Set processing or supports processing based on a first ratio, wherein PDU Set processing is supported or processing based on the first ratio is supported.

[0269] In one embodiment, if the first condition is met, a second indication message is sent; the first condition further includes at least one of the following: the first communication device supports processing based on a first ratio, and processing based on the first ratio is supported.

[0270] In this embodiment, the second indication information differs from the first indication information, which can solve the backward compatibility problem. For example, the RAN of R18 may ignore the first ratio if it does not recognize it. The RAN of R19, which supports the first ratio, receives and recognizes the first ratio and can return either the first indication information or the second indication information.

[0271] In one implementation, the first ratio satisfies at least one of the following:

[0272] The first ratio is either the second ratio or the third ratio;

[0273] The first ratio is used to determine whether the PDU Set succeeds or fails;

[0274] Wherein, the second ratio satisfies one of the following:

[0275] The second ratio is the maximum percentage of the first type of PDUs in the PDU Set when the PDU Set can be used;

[0276] When the proportion of the first type of PDU is less than or equal to the second ratio, the PDU Set can be used;

[0277] If the proportion of the first type of PDU is greater than or equal to the second ratio, the PDU Set cannot be used;

[0282] In one implementation, the proportion of the first type of PDU refers to the ratio calculated by dividing the PDUs of the first type in the PDU Set by the total number of PDUs in the PDU Set. The PDU Set can be used if the proportion of the first type of PDU is less than or equal to the second ratio (the maximum value of the proportion of the first type of PDU). For example, the PDU Set can be used if the ratio of failed PDUs to all PDUs in the PDU Set is less than or equal to 20%. If it exceeds 20%, for example, 25%, the PDU Set cannot be used.

[0283] The third ratio satisfies one of the following:

[0284] The third ratio is the minimum proportion of the second type of PDUs in the PDU Set when the PDU Set can be used;

[0285] If the proportion of the second type of PDU is greater than or equal to the third ratio, the PDU Set can be used;

[0286] If the proportion of the second type of PDU is less than or equal to the third ratio, the PDU Set cannot be used;

[0287] Wherein, the second type of PDU is the PDU in the PDU Set;

[0288] The second type of PDU includes at least one of the following: acquired PDU, successfully sent PDU, successfully received PDU, successfully transmitted PDU, and successful PDU.

[0289] In one implementation, the third ratio can also be understood as the minimum success rate.

[0290] In one implementation, the second type of PDU percentage refers to the ratio calculated by dividing the PDUs of the second type in the PDU Set by the total number of PDUs in the PDU Set. The PDU Set can be used if the second type of PDU percentage is greater than or equal to the third ratio (the minimum value of the second type of PDU percentage). For example, the PDU Set can be used if the ratio of successfully transmitted PDUs to all PDUs in the PDU Set is greater than or equal to 80%. If it is less than 80%, for example, 75%, the PDU Set cannot be used.

[0291] In one implementation, not acquiring a PDU can be understood as a discarded PDU, a PDU that failed to be transmitted, or a failed PDU.

[0292] PDU Sets can be used, for example, PDU Sets can be decoded.

[0299] If the second condition is met, the PDU Set is confirmed to be successful.

[0300] If the third condition is met, the PDU Set is determined to have failed.

[0301] in,

[0302] The second condition includes at least one of the following:

[0303] The percentage of successful PDUs is greater than or equal to the third ratio;

[0304] The percentage of failed or discarded PDUs is less than or equal to the second ratio;

[0305] The third condition includes at least one of the following:

[0306] The percentage of successful PDUs is less than or equal to the third ratio;

[0307] The percentage of PDUs that fail or are discarded is greater than or equal to the second ratio.

[0308] The term "failed PDU" can be an abbreviation for "PDU that failed to transmit".

[0309] In one implementation, the failed PDUs include discarded PDUs. In another implementation, the failed PDUs do not include discarded PDUs.

[0310] The term "successful PDU" can be an abbreviation for "PDU successfully transmitted".

[0311] In one implementation, the proportion of PDUs (such as first-class PDUs, second-class PDUs, successful PDUs, failed PDUs, discarded PDUs, etc.) can be the ratio of the total number of the PDUs (one or more) to the total number of all PDUs in the PDU Set, or the ratio of the total size of the PDUs (one or more) to the total size of all PDUs in the PDU Set.

[0312] For example, the percentage of discarded PDUs refers to the ratio calculated by using the discarded PDUs in the PDU Set as the numerator and all PDUs in the PDU Set as the denominator.

[0313] The percentage of discarded PDUs can include one of the following:

[0314] The percentage of the total number of discarded PDUs relative to the total number of PDUs in the PDU Set;

[0315] The ratio of the total size of discarded PDUs to the total size of all PDUs in the PDU Set.

[0316] In one implementation, the second or third ratio can be used for one of the following: determining that the PDU Set was successful, or determining that the PDU Set failed.

[0317] In one implementation, determining whether the PDU Set succeeded or failed based on the first ratio includes:

[0318] If the second condition is met, the PDU Set is confirmed to be successful.

[0319] If the third condition is met, the PDU Set is determined to have failed.

[0320] in,

[0325] The percentage of successful PDUs is less than or equal to the first ratio;

[0326] The percentage of failed or discarded PDUs is greater than or equal to the first ratio.

[0327] In one embodiment, the first ratio, the second ratio, or the third ratio is a value between 0 and 1.

[0328] Alternatively, the second ratio is the value obtained by subtracting the third ratio from 1;

[0329] Alternatively, the third ratio is the value obtained by subtracting the second ratio from 1.

[0330] In one implementation, the processing based on the first ratio includes: packet loss based on the first ratio in the event of PDU congestion.

[0331] In one implementation, a first ratio is used to determine whether a PDU Set success or failure falls under PDU Set QoS processing.

[0332] In one implementation, packet loss based on the first ratio may not be part of the PDU Set QoS processing.

[0333] In one embodiment, determining whether the PDU Set is successful or unsuccessful based on a first ratio includes: determining whether the PDU Set is successful or unsuccessful based on a first ratio in the case of received first information, wherein the first information includes the first ratio.

[0334] In one implementation, the first information further includes PSER.

[0336] In one implementation, upon receiving the first information and if the first communication device supports processing based on the first ratio, the success or failure of the PDU Set is determined according to the first ratio.

[0337] In one implementation, if the seventh condition is not met or the eighth condition is met, the first operation includes: not determining whether the PDU Set is successful or failed based on the first ratio;

[0338] The eighth condition includes at least one of the following:

[0339] The first communication device received the first ratio, but did not receive PSER;

[0340] The first communication device received the PSER, but did not receive the first ratio;

[0348] In one implementation, the first ratio or the third indication information implicitly indicates that at least one of PDU Set information identification and PDU Set information marking is supported.

[0349] In one implementation, at least one of PDU Set information identification and PDU Set information marking is supported, including at least one of the following: at least one of PDU Set information identification and PDU Set information marking in the uplink direction is supported, and at least one of PDU Set information identification and PDU Set information marking in the downlink direction is supported.

[0350] In one embodiment, the first ratio includes at least one of the following: a first ratio for the upward direction and a first ratio for the downward direction.

[0351] In this application embodiment, the corresponding processing methods of the radio access network side and the core network side are clarified after introducing the ratio of PDUs in the PDU Set (such as the minimum percentage of successful PDUs and the maximum percentage of failed PDUs). This can improve and enhance the processing of PDU Sets (such as determining whether a PDU Set is successful or failed, how to activate the marking of PDU Set information, and how to provide PDU Set information identification support indication), thereby improving the reliability of the system.

[0352] Please refer to Figure 3, which is a flowchart of a PDU Set processing method provided in an embodiment of this application. The method applies a second communication device, the first communication device including core network equipment (such as SMF), and the method includes the following steps:

[0353] Step 31: The second communication device performs a second operation, which includes at least one of the following:

[0354] Send first information to a first communication device, the first information including at least one of the following: a first ratio and third indication information, the third indication information being information for requesting the execution of processing based on the first ratio;

[0355] If the fourth condition is met, a fourth indication message is sent to the first communication device, the fourth indication message being used to indicate that at least one of PDU Set information identification and PDU Set information marking is supported;

[0356] If the fifth condition is met, a fifth instruction message is sent to the user plane function, the fifth instruction message being used to request the activation of the PDU Set information marker operation;

[0357] The fourth condition includes at least one of the following:

[0358] The first ratio is either nonexistent or unclear.

[0359] Processing based on the first ratio is not permitted or required;

[0360] The fifth condition includes at least one of the following:

[0361] Receive the first instruction information or the second instruction information sent by the first communication device;

[0362] There exists a first ratio or a requirement to perform processing based on the first ratio;

[0363] The first indication information is used to indicate one of the following: PDU Set processing is supported, or the first communication device supports PDU Set processing;

[0364] The second indication information is used to indicate one of the following: processing based on the first ratio is supported, or the first communication device supports processing based on the first ratio.

[0365] In one embodiment, the second communication device is a core network device, such as an SMF (Software-Defined Network).

[0366] In one embodiment, the first communication device is an access network device, such as a RAN network element, or a target RAN network element after handover.

[0367] In one implementation, at least one of PDU Set information identification and PDU Set information marking is supported, including at least one of the following:

[0368] There is protocol description information (e.g., the protocol description information describes a protocol including PDU Set information or information used to identify PDU Set information);

[0369] The user face functionality supports at least one of PDU Set information recognition and PDU Set information tagging.

[0370] In one implementation, the user plane functionality can be a PSA UPF.

[0371] In one embodiment, if the user plane function does not receive the fifth indication information, the PDU Set information marking operation is not activated. If the user plane function receives the fifth indication information, the PDU Set information marking operation is activated.

[0372] In one implementation, the existence of a first ratio means that a policy rule (such as a PCC rule) or a local configuration contains the first ratio.

[0373] In one embodiment, "unclear first ratio" means there is no requirement for a first ratio or the specific value of the first ratio is unclear. For example, if a PDU Set can be used, 100% of the PDUs are not required, but it is unclear what percentage of PDUs are needed. The reason for this uncertainty may be that the application function (such as AF) has not provided a specific value for the first ratio, or the packet header does not carry the value of the first ratio.

[0374] In one embodiment, processing based on a first ratio, such as network processing, is not allowed (e.g., network-based policies do not allow the first ratio to take a value).

[0375] In one embodiment, the execution of a first ratio-based process is not required, for example, if an application function (such as AF) does not request the execution of a first ratio-based process or if a policy rule (such as a PCC rule) does not contain information for requesting the execution of a first ratio-based process.

[0376] In one embodiment, the first ratio implicitly indicates a request to perform processing based on the first ratio.

[0377] In one implementation, PDU Set processing is supported and may include one of the following:

[0382] The network (such as at least one of a radio access network and a core network) supports processing based on the first ratio.

[0383] In one implementation, the first ratio may also be referred to as the PDU Set related ratio.

[0384] In one implementation, since the first ratio is a PDU Set related ratio, processing based on the first ratio can be understood as PDU Set processing based on the first ratio, that is, processing based on the first ratio also belongs to PDU Set processing.

[0385] In one embodiment, the PDU Set processing includes at least one of the following:

[0386] Process data packets at the data packet set granularity;

[0387] Apply PDU Set QoS;

[0393] In one implementation, the first ratio satisfies at least one of the following:

[0396] Wherein, the second ratio satisfies one of the following:

[0397] The second ratio is the maximum percentage of the first type of PDUs in the PDU Set when the PDU Set can be used;

[0398] When the proportion of the first type of PDU is less than or equal to the second ratio, the PDU Set can be used;

[0399] If the proportion of the first type of PDU is greater than or equal to the second ratio, the PDU Set cannot be used;

[0400] Wherein, the first type of PDU is the PDU in the PDU Set;

[0401] The first type of PDU includes at least one of the following: PDU that was not acquired, PDU that was discarded, PDU that failed to be transmitted, and PDU that failed to be transmitted.

[0402] In one implementation, not acquiring a PDU can be understood as a discarded PDU, a PDU that failed to be transmitted, or a failed PDU.

[0403] The third ratio satisfies one of the following:

[0404] The third ratio is the minimum proportion of the second type of PDUs in the PDU Set when the PDU Set can be used;

[0405] If the proportion of the second type of PDU is greater than or equal to the third ratio, the PDU Set can be used;

[0406] If the proportion of the second type of PDU is less than or equal to the third ratio, the PDU Set cannot be used;

[0407] Wherein, the second type of PDU is the PDU in the PDU Set;

[0408] The second type of PDU includes at least one of the following: acquired PDU, successfully sent PDU, successfully received PDU, successfully transmitted PDU, and successful PDU.

[0409] In one implementation, obtaining a PDU, successfully transmitting a PDU, or a successful PDU includes at least one of the following: a successfully received PDU (from the receiver's perspective) or a successfully transmitted PDU (from the sender's perspective).

[0410] In one implementation, the proportion of PDUs (such as first-class PDUs, second-class PDUs, successful PDUs, failed PDUs, discarded PDUs, etc.) can be the ratio of the total number of the PDUs (one or more) to the total number of all PDUs in the PDU Set, or the ratio of the total size of the PDUs (one or more) to the total size of all PDUs in the PDU Set.

[0411] For example, the percentage of discarded PDUs refers to the ratio calculated by using the discarded PDUs in the PDU Set as the numerator and all PDUs in the PDU Set as the denominator.

[0412] The percentage of discarded PDUs can include one of the following:

[0413] The percentage of the total number of discarded PDUs relative to the total number of PDUs in the PDU Set;

[0414] The ratio of the total size of discarded PDUs to the total size of all PDUs in the PDU Set.

[0415] In one implementation, the second or third ratio can be used for one of the following: determining that the PDU Set was successful, or determining that the PDU Set failed.

[0416] In one embodiment, the first ratio, the second ratio, or the third ratio is a value between 0 and 1.

[0417] Alternatively, the second ratio is the value obtained by subtracting the third ratio from 1;

[0418] Alternatively, the third ratio is the value obtained by subtracting the second ratio from 1.

[0419] In one implementation, the processing based on the first ratio includes at least one of the following:

[0420] The success or failure of the PDU Set is determined based on the first ratio;

[0421] Packet loss based on the first ratio.

[0422] In one implementation, the first information further includes: PSER.

[0423] In one implementation, the first ratio and PSER are in the same direction. For example, the first ratio and PSER in the up direction, or the first ratio and PSER in the down direction.

[0424] In one embodiment, sending the first information to the first communication device includes: requesting the first communication device to perform a process of determining whether the PDU Set is successful or failed based on the first ratio, and then sending the first ratio and PSER to the first communication device.

[0425] In one embodiment, sending the first information to the first communication device includes:

[0426] If the sixth condition is met, the first ratio is sent to the first communication device;

[0427] The sixth condition includes:

[0429] The first communication device is required to perform packet loss based on the first ratio;

[0434] Protocol description information exists;

[0435] The user plane function supports at least one of PDU Set information recognition and PDU Set information tagging.

[0436] In one implementation, the user plane function is a PSA UPF.

[0437] In one implementation, the absence of the PDU Set QoS parameter means that the policy rule (such as the PCC rule) or the local configuration does not contain the PDU Set QoS parameter.

[0438] In one implementation, the existence of Protocol Description (PD, which describes the protocol used by the service flow (e.g., the protocol described by the Protocol Description includes PDU Set information or information used to identify PDU Set information)) means that the policy rules or local configuration contain Protocol Description information.

[0439] In one implementation, the first ratio or the third indication information implicitly indicates that at least one of PDU Set information identification and PDU Set information marking is supported.

[0440] In one embodiment, the first ratio includes at least one of the following: a first ratio for the upward direction and a first ratio for the downward direction;

[0442] In this application embodiment, the corresponding processing methods of the radio access network side and the core network side are clarified after introducing the ratio of PDUs in the PDU Set (such as the minimum percentage of successful PDUs and the maximum percentage of failed PDUs). This can improve and enhance the processing of PDU Sets (such as determining whether a PDU Set is successful or failed, how to activate the marking of PDU Set information, and how to provide PDU Set information identification support indication), thereby improving the reliability of the system.

[0443] Implementation method one of this application:

[0444] Step 1: The SMF sends the first ratio to the RAN. The transmission of the first ratio may be independent of at least one of PSDB, PSER, or PSIHI.

[0445] Additionally, the SMF can send a third indication to the RAN, which is information requesting the execution of processing based on the first ratio. Alternatively, the first ratio can implicitly indicate the request for processing based on the first ratio.

[0446] In one implementation, since the first ratio is a PDU Set related ratio, processing based on the first ratio can be understood as PDU Set processing based on the first ratio, that is, processing based on the first ratio also belongs to PDU Set processing.

[0447] In one implementation, the processing based on the first ratio includes at least one of the following:

[0448] The success or failure of the PDU Set is determined based on the first ratio;

[0449] Packet loss based on the first ratio (e.g., in congestion situations).

[0450] In one implementation, "PDU Set successful" can be an abbreviation for "PDU Set transmission successful" or "PDU Set reception successful".

[0451] In one implementation, PDU Set failure can be an abbreviation for PDU Set transmission failure or PDU Set reception failure.

[0452] In one implementation, the SMF can send a first ratio and PSER to the RAN.

[0453] In one implementation, when the first ratio and PSER are sent together to the RAN, it may implicitly indicate a requirement to perform at least one of the following:

[0454] The success or failure of the PDU Set is determined based on the first ratio.

[0455] Packet loss is performed according to a first ratio (e.g., in the case of congestion).

[0456] In one implementation, if the first ratio is not sent to the RAN along with the PSER, the requirement to perform packet drop based on the first ratio can be implicitly indicated (e.g., in the case of congestion).

[0457] Step 2: If the RAN receives the first ratio and supports processing based on the first ratio, the RAN responds to the SMF with either a first indication message or a second indication message. The first indication message indicates one of the following: PDU Set processing is supported, or the RAN supports PDU Set processing; the second indication message indicates one of the following: processing based on the first ratio is supported, or the RAN supports processing based on the first ratio.

[0458] Step 3: The SMF activates the PSA UPF to perform at least one of PDU Set information identification and PDU Set information marking based on at least one of the first ratio, the first indication information, or the second indication information.

[0459] Implementation method two of this application:

[0460] Step 1: If the fourth condition is met, send a fourth indication message to indicate that at least one of PDU Set information identification and PDU Set information marking is supported;

[0461] The fourth condition includes at least one of the following:

[0467] Protocol description information exists;

[0468] The user plane function supports at least one of PDU Set information recognition and PDU Set information tagging.

[0469] In this embodiment of the application, after introducing the PDU Set ratio, in addition to packet loss, the impact on other PDU Set processing is addressed: such as the criteria for PDU Set success and failure, how to change the conditions for SMF to send PDU Set information marking support indication, how to trigger RAN to feed back PDU Set information support indication, and how SMF to trigger PSA UPF to mark PDU Set information.
