[0023] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as User Equipment (UE), and can be a mobile phone, tablet computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home devices (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game consoles, personal computers (PCs), ATMs, or self-service machines, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment. Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit. Access network equipment may include base stations, Wireless Local Area Network (WLAN) access points (APs), or Wireless Fidelity (WiFi) nodes, etc.In this context, a base station may be referred to as a Node B (NB), Evolved Node B (eNB), Next Generation Node B (gNB), New Radio Node B (NR Node B), Access Point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B, Transmit / Receive Point (TRP), Non-Terrestrial Network (NTN) equipment (such as a satellite or high altitude platform station), or any other suitable term in the relevant field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that the specific type of base station is not limited in the embodiments of this application.

[0024] It should be noted that, in this embodiment of the application, the objects that are segmented and transmitted through the segmented transmission mechanism of the RRC layer (such as segmented AI data or segmented RRC messages) are collectively referred to as segment objects, and the RRC messages that carry the segments of the segment objects are collectively referred to as RRC segmented transmission messages (such as DLDedicatedMessageSegment messages or ULDedicatedMessageSegment messages).

[0025] In NR systems, the maximum length of a Service Data Unit (SDU) supported by the Packet Data Convergence Protocol (PDCP) layer is 9000 bytes. With the introduction of new features, the maximum length of a (encoded) RRC message can exceed 9000 bytes. Therefore, the 3GPP RAN2 working group introduced an RRC segmentation transmission mechanism. This mechanism first segments the RRC message, assigning each segment a sequence number starting from 0 and incrementing sequentially. Each segment is then placed into an RRC segmented transmission message for transmission, ensuring that the encoded RRC segmented transmission message does not exceed 9000 bytes. The segment number (segmentNumber) and segment type (used for intermediate segments (notlastSegment) or final segments (lastSegment)) within the RRC segmented transmission message instruct the receiver to reassemble the segments.

[0026] In existing segmented transmission mechanisms, the receiver, after receiving and assembling all segments, decodes them as an encoded RRC message and performs corresponding processing. However, the newly introduced AI data transmitted via RRC ranges in size from tens of KB (kilobytes) to hundreds of MB (megabytes), also requiring segmented transmission via the RRC segmented transmission mechanism. However, after assembly by the receiver, it is only AI data, not an encoded RRC message. If the receiver assembles and decodes it according to the existing segmented transmission mechanism, decoding errors will occur, leading to the discarding of AI data (or a portion of it), ultimately resulting in the inability to receive AI data correctly and impacting the end-user experience.

[0027] It should be noted that although this application specification uses NR segmentation objects as an example for illustration, these technologies can also be applied to systems other than NR systems, such as 6G communication systems, or to the processing of other communication entities or protocol layers with similar problems. This application does not impose any restrictions on this.

[0028] The segmented transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0029] In step S101, the Radio Resource Control (RRC) layer receives multiple RRC segment transmission messages corresponding to the first segment object from the sender.

[0030] Each RRC segment transmission message includes a segment of a first segment object, and at least one RRC segment transmission message is associated with first indication information, which is used to directly or indirectly indicate the processing operation associated with the first segment object.

[0031] In the embodiments of this application, the sender can be a base station and the receiver can be a terminal device, or the sender can be a terminal device and the receiver can be a base station.

[0032] The first indication information associated with at least one RRC segment transmission message can be explicit or implicit, and is used to directly or indirectly indicate the processing operation information of the first segment object.

[0033] In some embodiments, the first indication information includes at least one of the following: Processing operation information for the first segment object; The segment object type information of the first segment object; Information on whether the first segment object is an RRC message.

[0034] The segmented object type information includes at least one of the following: RRC message; AI models; AI model parameters; AI data.

[0035] The processing operation includes any one of the following: The segments are assembled at the RRC layer, and the assembled segment objects are then decoded using RRC messages. The segments are assembled at the RRC layer, and the assembled segment objects are submitted to the preset protocol layer above the RRC layer. The segments are then delivered to the preset protocol layer above the RRC layer. Process it as an RRC message; It is processed as an AI model, AI model parameters, or AI data.

[0036] In step S102, a processing operation is performed on the first segment object according to the first instruction information.

[0037] In some embodiments, the receiver may include an RRC layer and an upper layer above the RRC layer, wherein the upper layer above the RRC layer may include at least one preset protocol layer, such as an AI layer, an application layer, an AI model layer, or an AI data layer, etc.

[0038] In some embodiments, the receiver may perform corresponding processing operations based on the processing operation information of the first segment object in the first indication information.

[0039] In some embodiments, the first indication information may be the segment object type information of the first segment object. The receiver can perform corresponding processing operations based on the segment object type of the first segment object and the preset correspondence between the segment object type and the processing operation. For example, if the segment object type of the first segment object is an RRC message, the receiver performs processing operation A (e.g., processing it as an RRC message); if the segment object type of the first segment object is an AI model, the receiver performs processing operation B (e.g., assembling the segments at the RRC layer and submitting the assembled segment object to the preset protocol layer above the RRC layer); if the segment object type of the first segment object is AI data, the receiver performs processing operation C (e.g., submitting the segments to the preset protocol layer above the RRC layer).

[0040] In some embodiments, the first indication information may be information about whether the first segment object is an RRC message, and the receiver can perform preset processing operations based on whether the first segment object is an RRC message. For example, if the first segment object is an RRC message, the receiver can perform processing operation D (assemble the segment at the RRC layer and decode the assembled segment object as an RRC message); otherwise, the receiver can perform processing operation E (assemble the segment at the RRC layer and submit the assembled segment object to the preset protocol layer above the RRC layer).

[0041] Of course, the first indication information can also be any combination of the following: the processing operation information of the first segment object; the segment object type information of the first segment object; and the information of whether the first segment object is an RRC message. For example, the receiver can determine the corresponding processing operation information based on the fact that the first segment object is an RRC message and the segment object type of the first segment object (for example, it can be divided into different segment object types based on the purpose or length of the RRC message) and the preset correspondence between the processing operation.

[0042] It is understandable that the processing operation can be any combination of the above processing operations. For example, the processing operation can be to process the segment as an RRC message while assembling the segment at the RRC layer and submitting the assembled segment object to the preset protocol layer in the upper layer of the RRC layer. This allows the RRC layer and the preset protocol layer in the upper layer of the RRC layer to work together to further improve the flexibility of segment transmission.

[0043] By adopting the above technical solution, the processing operation information of the first segment object can be indicated through the first indication information, which can solve the error processing that may occur when transmitting big data (such as AI data) through the existing segment transmission mechanism in related technologies, avoid the RRC decoding error caused by this, and thus avoid the problem of the segment object being discarded, thereby improving the user experience.

[0044] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: at least one RRC segmentation transmission message includes first indication information.

[0045] Figure 3 An interactive schematic diagram of a segmented transmission method provided in an embodiment of this disclosure is shown, such as... Figure 3 As shown, the sender sends RRC segment transmission messages to the receiver for the segment sequence numbers of the first segment object, which are n+1 segments from 0 to n. Among them, at least one RRC segment transmission message for a segment with a preset segment sequence number or a preset segment type includes the first indication information.

[0046] The specific RRC segment transmission messages that include the first indication information can be flexibly configured as needed. The first indication information can be included in all RRC segment transmission messages, or it can be included only in some RRC segment transmission messages. For example, the first indication information can be included in the RRC segment transmission messages corresponding to segments with one or more preset segment numbers. Figure 3 The first indication information can be included in the RRC segment transmission message corresponding to the segment with segment number 0, or it can be included in the RRC segment transmission message corresponding to the segment with segment type "end segment". Alternatively, both methods can be combined; for example, the first indication information can be included in the RRC segment transmission messages corresponding to both the segment with segment number x and the segment with segment type "end segment".

[0047] In another embodiment, at least one RRC segment transmission message includes first indication information, including: the RRC segment transmission message corresponding to the first segment (segment with segment number 0) or the last segment (segment with segment type "last segment" or "end segment") of the first segment object includes the first indication information. Including this first indication information in the RRC segment transmission message corresponding to the segment with segment number 0 is beneficial for the receiver to obtain information related to the first segment object earlier and perform related processing operations earlier.

[0048] By adopting the above technical solution, the processing operation information of the first segment object can be indicated by the first indication information included in the RRC segment transmission message. This solves the problem of error processing that may occur when transmitting big data (such as AI data) through the existing segment transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded, thereby improving the user experience.

[0049] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: a first signaling radio bearer that transmits the RRC segmentation transmission message is associated with the first indication information, wherein different signaling radio bearers are associated with different processing operations.

[0050] Figure 4 This illustration shows another schematic flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 4 As shown, step S102 may include the following steps.

[0051] In step S1021, the processing operation is determined based on the first signaling radio bearer that transmits the RRC segmented transmission message.

[0052] In step S1022, a processing operation is performed on the first segment object.

[0053] Taking NR as an example, RRC messages are usually transmitted through Signaling Radio Bearer (SRB). In this embodiment, the first indication information can be characterized by associating different signaling radio bearers, that is, different segment objects transmitted by different signaling radio bearers are associated with different first indication information.

[0054] Different signaling radio bearers can have different identifiers. For example, the second signaling radio bearer can be any one of SRB0-3 in the related technology, while the first signaling radio bearer can be a newly defined SRBx (where x is not equal to any one of 0-3).

[0055] The receiver can determine the processing operation based on the preset correspondence between signaling radio bearers and processing operations, and the signaling radio bearer corresponding to the first segment object, and perform the corresponding processing operation on the first segment object according to the processing operation information.

[0056] Figure 5 This illustration shows another interactive diagram of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 5 As shown, the sender transmits RRC segment transmission messages to the receiver for n+1 segments of the first segment object, with segment numbers from 0 to n. Each RRC segment transmission message is carried on a first signaling radio bearer (SRBx), which implicitly represents the first indication information. The receiver can obtain the first indication information based on the preset correspondence between signaling radio bearers and processing operation information, as well as the first signaling radio bearer (SRBx) of the first segment object, thereby determining the processing operation information corresponding to the first signaling radio bearer (SRBx) and performing corresponding processing operations on the first segment object according to the processing operation information.

[0057] By adopting the above technical solution, the processing operation information of the first segment object can be determined by the first indication information implicitly indicated by the signaling radio bearer corresponding to the RRC segmented transmission message. This solves the problem of error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.

[0058] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: the first message type of the RRC segmentation transmission message is associated with the first indication information, wherein RRC segmentation transmission messages of different message types are associated with different processing operations.

[0059] Figure 6 This illustration shows another schematic flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 6 As shown, step S102 may include the following steps.

[0060] In step S1023, the processing operation is determined based on the first message type of the RRC segmented transmission message.

[0061] In step S1024, a processing operation is performed on the first segment object.

[0062] Taking NR downlink as an example (uplink is similar and will not be elaborated upon), in order to solve the problem that the length of RRC messages may exceed the maximum length of PDCP SDU, 3GPP defines DLDedicatedMessageSegment segmented transmission messages to process RRC messages in a segmented manner. This includes assigning a segment number (segmentNumber) to each segment. The segment number of the first segment is 0, and the segment numbers of subsequent segments are incremented by 1 sequentially. DLDedicatedMessageSegment segmented transmission messages include a segment type rrc-MessageSegmentType. The value of rrc-MessageSegmentType is lastSegment, which indicates that the segment in the RRC segmented transmission message is the last segment. The value of rrc-MessageSegmentType is notLastSegment, which indicates that the segment in the RRC segmented transmission message is an intermediate segment. DLDedicatedMessageSegment segmented transmission messages also include the segments of the message transmission, and the specific information element is rrc-MessageSegmentContainer.

[0063] In some possible implementations, an RRC segmented transmission message of a different type than DLDedicatedMessageSegment can be predefined so that the message type of the RRC segmented transmission message implicitly indicates the first indication information. For example, the receiver can determine the processing operation based on the predefined correspondence between the message type and the processing operation, and the first message type corresponding to the first segment object, and perform the corresponding processing operation on the first segment object according to the processing operation information.

[0064] For example, when the message type of the RRC segmented transmission message is DLDedicatedMessageSegment2, it can be determined that the processing operation corresponding to the first segment object is processing operation A, and the corresponding processing operation is performed on the first segment object according to the processing operation information A.

[0065] When the message type of the RRC segmented transmission message is DLDedicatedMessageSegment3, it can be determined that the processing operation corresponding to the first segment object is processing operation B, and the corresponding processing operation is performed on the first segment object according to the processing operation information B.

[0066] Figure 7 This illustration shows another interactive diagram of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 7 As shown, the sender sends the receiver RRC segment transmission messages corresponding to the segment numbers 0-n (n+1 in total) of the first segment object. Each RRC segment transmission message uses the first message type, meaning that different message types implicitly indicate different processing operations. The receiver can determine the processing operation based on the preset correspondence between message types and processing operations, and the first message type corresponding to the first segment object, and then perform the corresponding processing operation on the first segment object according to this processing operation information.

[0067] By adopting the above technical solution, the processing operation information of the first segment object can be determined by the first indication information implicitly indicated by the message type of the RRC segmented transmission message. This solves the error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.

[0068] The maximum length supported by the existing segmentation mechanism does not meet the transmission requirements of AI data. Taking NR downlink as an example (uplink is similar and will not be described in detail), the maximum number of segments defined in DLDedicatedMessageSegment is 5, and the maximum length of each segment is 9000 bytes. That is, the maximum length of the encoded RRC message supported by downlink is 45KB.

[0069] To address this issue, in some embodiments, the encapsulation format of DLDedicatedMessageSegment can be extended in any of the following ways by adding an extended segment sequence number, thereby enabling the extended DLDedicatedMessageSegment to meet the large data volume requirements of AI data. In this case, the information cell with the extended segment sequence number is used to extend the maximum segment sequence number of RRC segment transmission.

[0070] Method 1: Extended segment number is used to represent the segment number of the first segment object when the maximum segment number of the first segment object is greater than the first threshold.

[0071] In some embodiments, the first threshold may be, for example, the maximum segment number under an existing segmentation mechanism.

[0072] For example, a new information element 'x' can be added to the encapsulation format DLDedicatedMessageSegment of the segment object. The value range of this information element can be set to a large value according to the data volume requirements of the AI ​​data. For example, it can support up to 100,000 segments (in this case, the maximum supported data length is 100,000 * 9KBs = 900MBs), so the value range can be 0..99999. If the encapsulation format DLDedicatedMessageSegment includes this information element 'x', the existing information element segmentNumber is ignored, and the value of this information element 'x' is used as the segment number. Otherwise, the existing information element segmentNumber - r16 is used as the segment number.

[0073] Method 2: Extended segment number and basic segment number are used to characterize the segment number of the first segment object when the segment number of the first segment object is greater than the first threshold.

[0074] For example, a new information element y can be added to the encapsulation format DLDedicatedMessageSegment of the segment object. When the encapsulation format DLDedicatedMessageSegment includes this information element y, the bits of information element y and segmentNumber are combined to represent the segment number. For example, the bits of segmentNumber are used as the least significant bits of the segment number, and the bits of information element y are used as the most significant bits of the segment number; or, the bits of segmentNumber are used as the most significant bits of the segment number, and the bits of information element y are used as the least significant bits of the segment number.

[0075] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: the first indication information is associated with a first encapsulation format used by the RRC segmentation transmission message. Specifically, RRC segmentation transmission messages using different encapsulation formats are associated with different processing operations.

[0076] Figure 8 This illustration shows another schematic flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 8 As shown, step S102 may include the following steps.

[0077] In step S1025, the processing operation is determined according to the first encapsulation format adopted by the RRC segmented transmission message.

[0078] In step S1026, a processing operation is performed on the first segment object.

[0079] In some possible implementations, the first encapsulation format includes cells with extended segment numbers, while the second encapsulation format does not include cells with extended segment numbers; or, the second encapsulation format includes cells with extended segment numbers, while the first encapsulation format does not include cells with extended segment numbers. In this embodiment, the extended segment number is either the newly added cell x in method one or the newly added cell y in method two.

[0080] Taking a cell in the first encapsulation format that includes an extended segmentation number and a cell in the second encapsulation format that does not include an extended segmentation number as an example, Figure 9 This illustration shows another interactive diagram of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 9As shown, the sender sends the receiver RRC segment transmission messages corresponding to the segment numbers 0-n (n+1 in total) of the first segment object. Each RRC segment transmission message uses the first encapsulation format, meaning different encapsulation formats implicitly indicate different processing operations. The receiver can determine the processing operation based on the preset correspondence between encapsulation formats and processing operations, and the first encapsulation format corresponding to the first segment object. The receiver then performs the corresponding processing operation on the first segment object based on this processing operation information.

[0081] By adopting the above technical solution, the processing operation information of the first segment object can be determined through the first indication information implicitly indicated by the encapsulation format of the RRC segmented transmission message. This solves the error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.

[0082] Figure 10 This illustration shows a flowchart of a segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 10 As shown, this method can be applied to the sender, and the method may include the following steps.

[0083] In step S201, a corresponding RRC segment transmission message is generated for each first segment of the first segment object at the Radio Resource Control (RRC) layer. The first segment object corresponds to multiple first segments, and the RRC segment transmission message includes the first segment.

[0084] In step S202, the RRC segment transmission message corresponding to each first segment is sent to the receiver.

[0085] In this process, at least one RRC segment transmission message is associated with first indication information, which is used to directly or indirectly indicate the processing operation associated with the first segment object.

[0086] In some embodiments, the first indication information includes at least one of the following: Processing operation information for the first segment object; The segment object type information of the first segment object; Information on whether the first segment object is an RRC message.

[0087] The segmented object type information includes at least one of the following: RRC message; AI models; AI model parameters; AI data.

[0088] The processing operation includes any one of the following: The segments are assembled at the RRC layer, and the assembled segment objects are then decoded using RRC messages. The segments are assembled at the RRC layer, and the assembled segment objects are submitted to the preset protocol layer above the RRC layer. The segments are then delivered to the preset protocol layer above the RRC layer. Process it as an RRC message; It is processed as an AI model, AI model parameters, or AI data.

[0089] The description of the first instruction information and processing operation can be found in the description of the first aspect embodiment, and will not be repeated here.

[0090] By adopting the above technical solution, the processing operation information of the first segment object can be indicated through the first indication information, which can solve the error processing that may occur when transmitting big data (such as AI data) through the existing segment transmission mechanism in related technologies, avoid the RRC decoding error caused by this, and thus avoid the problem of the segment object being discarded, thereby improving the user experience.

[0091] In some embodiments, the receiver may include an RRC layer and an upper layer above the RRC layer, wherein the upper layer above the RRC layer may include at least one preset protocol layer, such as an AI layer, an application layer, an AI model layer, or an AI data layer, etc.

[0092] Figure 11 This illustration shows a flowchart of a segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 11 As shown, this method can be applied to the sender, and the method may also include the following steps.

[0093] In step S203, the first segment object is segmented to generate multiple first segments.

[0094] In some embodiments, the first segment object can be segmented to generate multiple first segments in any of the following ways.

[0095] Method 1: Divide the first segment object into multiple first segments at the RRC layer.

[0096] Method 2: The first segment object is segmented into multiple first segments in the preset protocol layer above the RRC layer, and the multiple first segments are received in the RRC layer.

[0097] For example, the AI ​​layer above the RRC layer can segment the AI ​​data to generate multiple first segments, and send these multiple first segments sequentially to the RRC layer, which then receives the multiple first segments sequentially. Alternatively, the AI ​​layer can segment the AI ​​data to generate multiple first segments, and generate a segment number for each segment sequentially, then send the first segment and its segment number to the RRC layer. This application does not impose any limitations on this.

[0098] In the above method two, the upper layer of the RRC layer can also send at least one of the following information to the RRC layer: information about the first segment object associated with each first segment, or information about the segment type of each first segment (e.g., whether it is the last segment), or information about the total number of segments, or information indicating the end of the segment, so as to better coordinate the segmentation of the first segment object.

[0099] By adopting the above technical solution, the first segment object can be segmented into multiple first segments through the RRC layer, or through the collaboration between the RRC layer and the upper layer of the RRC layer, which can improve the flexibility of segmentation processing of the first segment object.

[0100] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: at least one RRC segmentation transmission message includes first indication information.

[0101] like Figure 3 As shown, the sender sends RRC segment transmission messages to the receiver for the segment sequence numbers of the first segment object, which are n+1 segments from 0 to n. Among them, at least one RRC segment transmission message for a segment with a preset segment sequence number or a preset segment type includes the first indication information.

[0102] The specific RRC segment transmission messages that include the first indication information can be flexibly configured as needed. The first indication information can be included in all RRC segment transmission messages, or it can be included only in some RRC segment transmission messages. For example, the first indication information can be included in the RRC segment transmission messages corresponding to segments with one or more preset segment numbers. Figure 3 The first indication information can be included in the RRC segment transmission message corresponding to the segment with segment number 0, or it can be included in the RRC segment transmission message corresponding to the segment with segment type "end segment". Alternatively, both methods can be combined; for example, the first indication information can be included in the RRC segment transmission messages corresponding to both the segment with segment number x and the segment with segment type "end segment".

[0103] In another embodiment, at least one RRC segment transmission message includes first indication information, including: the RRC segment transmission message corresponding to the first segment (segment with segment number 0) or the last segment (segment with segment type last segment or end segment) of the first segment object includes the first indication information.

[0104] By adopting the above technical solution, the processing operation information of the first segment object can be indicated by the first indication information included in the RRC segment transmission message. This solves the problem of error processing that may occur when transmitting big data (such as AI data) through the existing segment transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded, thereby improving the user experience.

[0105] In some embodiments, at least one RRC segmentation transmission message is associated with first indication information, including: a first signaling radio bearer that transmits the RRC segmentation transmission message is associated with the first indication information, wherein different signaling radio bearers are associated with different processing operations.

[0106] Figure 11 This illustration shows another flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 11 As shown, step S202 may include the following steps.

[0107] In step S2021, the RRC segment transmission message corresponding to each first segment is sent to the receiver through the first signaling radio bearer.

[0108] For example, the sender can determine the corresponding first signaling radio bearer based on the preset correspondence between signaling radio bearers and processing operations, and the processing operation corresponding to the first segment object, and send the RRC segment transmission message corresponding to each first segment to the receiver through the first signaling radio bearer.

[0109] For details regarding the interaction between the sender and receiver when the first signaling radio bearer is associated with the first indication information in the transmission of RRC segmented transmission messages, please refer to the relevant description in the first aspect embodiment, which will not be elaborated here.

[0110] By adopting the above technical solution, the processing operation information of the first segment object can be determined by the first indication information implicitly indicated by the signaling radio bearer corresponding to the RRC segmented transmission message. This solves the problem of error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.

[0111] In another embodiment, at least one RRC segmented transmission message is associated with first indication information, including: the first message type of the RRC segmented transmission message is associated with the first indication information.

[0112] Among them, different message types of RRC segmented transmission messages are associated with different processing operations.

[0113] Figure 12 This illustration shows another schematic flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 12 As shown, step S202 may include the following steps.

[0114] In step S2022, an RRC segment transmission message of the first message type corresponding to each first segment is sent to the receiver.

[0115] For example, the sender can determine the corresponding first message type based on the preset correspondence between message types and processing operations, and the processing operation corresponding to the first segment object, and send an RRC segment transmission message with the first message type corresponding to each first segment to the receiver.

[0116] For details regarding the interaction between the sender and receiver when the first message type of the RRC segmented transmission message is associated with the first indication information, please refer to the relevant description in the first aspect embodiment, which will not be elaborated here.

[0117] By adopting the above technical solution, the processing operation information of the first segment object can be determined by the first indication information implicitly indicated by the message type of the RRC segmented transmission message. This solves the error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.

[0118] In another embodiment, at least one RRC segmentation transmission message is associated with first indication information, including: the first encapsulation format used by the RRC segmentation transmission message is associated with the first indication information.

[0119] Among them, RRC segmented transmission messages with different encapsulation formats are associated with different processing operations.

[0120] Figure 13 This illustration shows another schematic flowchart of the segmented transmission method provided in an embodiment of the present disclosure, such as... Figure 13 As shown, step S202 may include the following steps.

[0121] In step S2023, the RRC segment transmission message corresponding to each first segment, encapsulated in the first encapsulation format, is sent to the receiver.

[0122] In some possible implementations, the first encapsulation format includes cells with extended segment numbers, while the second encapsulation format does not include cells with extended segment numbers; or, the second encapsulation format includes cells with extended segment numbers, while the first encapsulation format does not include cells with extended segment numbers.

[0123] For example, the sender can determine the corresponding first encapsulation format based on the preset correspondence between the encapsulation format and the processing operation, and the processing operation corresponding to the first segment object, and send the RRC segment transmission message encapsulated in the first encapsulation format to the receiver for each first segment.

[0124] For details regarding the interaction between the sender and receiver when the first encapsulation format of the RRC segmented transmission message is associated with the first indication information, please refer to the relevant description in the first aspect embodiment, which will not be elaborated here.

[0125] By adopting the above technical solution, the processing operation information of the first segment object can be determined through the first indication information implicitly indicated by the encapsulation format of the RRC segmented transmission message. This solves the error processing that may occur when transmitting big data (such as AI data) through the existing segmented transmission mechanism in related technologies, avoids the RRC decoding error caused by this, and prevents the segment object from being discarded. While improving the user experience, the implicit indication of the first indication information can also further reduce overhead and improve the efficiency of segmented transmission.
