[0080] For ease of understanding the embodiments of the present application, the transmission schemes of the User Plane (UP) and Control Plane (CP) related to the present application are described.

[0081] The User Plane is the part of a communication system that connects user equipment and applications, including the radio access network and the core network. The goal of the User Plane is to provide faster data transfer speeds, better network coverage, lower latency, and higher security. The protocol responsible for transmitting and processing user data streams is called the User Plane. The nodes of the User Plane include UE, gNB, UPF, and the Data Analysis Function (DAF) for analyzing User Plane data.

[0082] The Control Plane is one of the core parts of a communication system, mainly responsible for network management and protocol control, and determining the transmission paths and quality of service of all information in the network. The protocol responsible for transmitting and processing system protocol signaling is called the Control Plane. The nodes of the Control Plane include UE, gNB, AMF, and the Data Control Function (DCF).

[0084] Physical Layer (abbreviated as PHY);

[0085] Media Access Control (MAC) layer;

[0086] Radio Link Control (RLC) layer;

[0087] Packet Data Convergence Protocol (PDCP) layer;

[0088] Service Data Adaptation Protocol (SDAP) layer.

[0089] Figure 3 It is a schematic diagram of a Control Plane protocol architecture.

[0090] Among them, the Control Plane of UE may include the following protocol layers:

[0091] PHY layer;

[0092] MAC layer;

[0093] RLC layer;

[0094] PDCP layer;

[0095] Radio Resource Control (RRC) layer;

[0096] Non-Access Stratum (NAS).

[0097] Among them, the control plane of an access network device (such as a gNB) may include the following protocol layers:

[0098] PHY layer;

[0099] MAC layer;

[0100] RLC layer;

[0101] PDCP layer;

[0102] Radio Resource Control (RRC) layer.

[0103] Among them, the control plane of the core network function (such as AMF) includes the NAS layer. The NAS layer of the UE and the NAS layer of the core network function can communicate directly.

[0104] To facilitate the understanding of the embodiments of this application, the LTE positioning protocol (LPP) solution related to this application is described.

[0105] Figure 4 is a structural diagram of the positioning protocol stack between a UE and an LMF. As Figure 4 shown, the protocol stack on the UE side may include the following protocol layers: Layer 1 (L1), MAC, RLC, PDCP, RRC, NAS, LPP.

[0106] The protocol stack on the access network device side (such as Next Generation (NG) RAN) for communicating with the UE side may include the following protocol layers: L1, MAC, RLC, PDCP, RRC, relay layer.

[0107] The protocol stack for communication between the access network device side (e.g., Next Generation (NG) RAN) and the AMP side may include the following protocol layers: L1, Layer 2 (L2), Internet Protocol (IP), Stream Control Transmission Protocol (SCTP), Protocol for NG Interface (NGAP), and relay layer. Among them, the relay layer used by the access network device side to communicate with the UE and the AMF may be common.

[0108] Among them, the access network device and the UE may communicate through the NR-Uu interface or the LTE-Uu interface, or, with the evolution of the standard, may also communicate through other interfaces. This application is not limited thereto.

[0109] The protocol stack for communication between the AMF side and the access network device may include the following protocol layers: L1, L2, IP, SCTP, NGAP. The AMF side also includes the NAS layer for communicating with the UE.

[0110] Among them, the AMF and the access network device may communicate through the NG-C interface, or, with the evolution of the standard, the name of this interface may also be replaced by other names, or may also communicate through other interfaces. This application is not limited thereto.

[0111] The protocol stack for communication between the AMF side and the LMF may include the following protocol layers: L1, L2, IP, Transmission Control Protocol (TCP), Transport Layer Security (TLS), Hypertext Transfer Protocol / 2 (HTTP / 2).

[0112] The protocol stack on the LMF side may include the following protocol layers: L1, L2, IP, TCP, TLS, HTTP / 2, for communicating with the AMF. The LMF side also includes the LPP layer for communicating with the UE.

[0113] Among them, the AMF and the LMF may communicate through the NL1 interface, or, with the evolution of the standard, the name of this interface may also be replaced by other names, or may also communicate through other interfaces. This application is not limited thereto.

[0114] In this LPP solution, data is transmitted through the control plane via the LPP layer. Taking the direction from the UE to the core network as an example, and vice versa, the data first undergoes encoding in the LPP layer, then encoding in the NAS layer, encryption and integrity protection in the NAS layer, then Abstract Syntax Notation One (ASN.1) encoding in the RRC layer, then integrity protection and encryption in the PDCP layer, then passes through the Acknowledged Mode (AM) of the RLC layer, passes through the MAC layer, and is transmitted through the L1 air interface. On the base station side, through the AM mode, integrity protection verification, decryption, and RRC decoding of the PDCP layer, the base station transmits the payload of the NAS layer data to the NAS layer of the peer, i.e., the AMF. Then the NAS layer of the AMF transparently passes the payload to the LPP layer of the LMF. Finally, the LPP layer of the LMF decodes to obtain the data. In this process, encoding and decoding operations are performed on the LPP layer, RRC layer, and NAS layer, and encryption / decryption and integrity protection operations are performed on the NAS layer and PDCP layer, which improves data security but also increases data complexity and transmission delay.

[0115] Figure 5 It is a structural diagram of the positioning protocol stack between an access network device (such as NG RAN) and the LMF.

[0116] As Figure 5 shown, the protocol stack on the access network device side (such as NG RAN) can include the following protocol layers: L1, L2, IP, SCTP, NGAP, and NR Positioning Protocol a (NRPPa).

[0117] The protocol stack for the AMF to communicate with the access network device side (such as NG RAN) can include the following protocol layers: L1, L2, IP, SCTP, NGAP.

[0118] The protocol stack for the AMF to communicate with the LMF side can include the following protocol layers: L1, L2, IP, TCP, TLS, HTTP / 2.

[0119] The protocol stack on the LMF side can include the following protocol layers: L1, L2, IP, TCP, TLS, HTTP / 2, for communicating with the AMF. The LMF side also includes the NRPPa layer for communicating with the access network device.

[0120] In some scenarios, it is considered to introduce a data plane for data transmission and data processing in a communication system. For example, it includes network devices and traffic processing mechanisms. The goal of the data plane is to provide more efficient and stable data transmission and processing capabilities. This data plane can be a data plane architecture independent of the traditional user plane, capable of systematically addressing the challenges of non-user plane data management and value monetization in the communication system.

[0121] For example, the data plane can be composed of a data plane function on the core network side, a data plane function on the radio access network side, and a data plane function on the UE side, with end-to-end connectivity. For example, the data plane is responsible for data control, including but not limited to data collection coordination, data collection configuration, and data transmission configuration, etc. The data plane is also responsible for functions such as data acquisition, data transmission, data preprocessing, data privacy and security, data analysis, data storage, and data services. Figure 6 A schematic diagram of a data plane is shown.

[0122] As Figure 6 shown, the data plane function on the UE side can include at least one of the following functions:

[0123] Terminal data control, data security and trust, data transmission, specified data services, data consumption / provision.

[0124] The data plane function on the radio access network side can include at least one of the following functions:

[0125] Wireless data control, data security and trust, data warehouse, data transmission, wireless data services, data provision / consumption.

[0126] The data plane function on the core network side can include at least one of the following functions:

[0127] Data control, data security and trust, data warehouse, data analysis, data preprocessing, data transmission, data services, data provision / consumption.

[0128] The network external function can include at least one of the following functions:

[0129] Data provision, data consumption.

[0130] Figure 7 It is a data plane protocol structure diagram between a UE and an access network device provided by an embodiment of the present application.

[0131] As Figure 7 shown, above the PDCP layer of the UE and the access network device, a first sub-layer (or Data Service Application Protocol (DSAP) layer) can be included to implement the data plane function.

[0132] In some scenarios, a first data plane function may be introduced on the core network side to implement the data plane function on the core network side. Optionally, the name of the first data plane function is only an example and may also be replaced with other names. For example, Data Control Function (DCF), Data Plane Adaptation Protocol (DPAP) function, etc. This application does not make any limitations in this regard.

[0133] It should be understood that the first data plane function may be a newly added functional entity, or it may also be a data plane processing module added to an existing core network functional entity to implement the data plane function. This application does not make any limitations in this regard.

[0134] Figure 8 It is a data plane protocol structure diagram between a UE and a first data plane function provided by an embodiment of this application.

[0135] As Figure 8 shown, above the PDCP layer of the UE and the access network device, there may be a first sublayer for implementing the data plane function. The first data plane function includes a first data plane function protocol layer. Adding a first data plane function protocol layer above the first sublayer of the UE is used to implement the data plane function between the UE and the first data plane function.

[0136] It should be understood that the name of the first data plane function protocol layer is only an example and may also be replaced with other names. For example, DCF layer, DPAP layer, etc. This application does not make any limitations in this regard.

[0137] In the related art, there are various services in the communication system. For example, traditional services (such as video services, short message services, etc.) and data plane services related to Artificial Intelligence (AI), communication sensing services, Long Term Evolution (LTE) Positioning Protocol (LPP) services, etc. Therefore, how to achieve efficient transmission of services is an urgent problem to be solved.

[0138] For example, when the collection, aggregation, and preprocessing of data are performed on the core network, when the data reaches the core network, affected by the network architecture, the data may undergo multiple encryption, integrity protection, encoding, and compression processes. Since the data does not need to be parsed and processed on the access network side and is only transparently transmitted, the core network can reduce the number of encryption, integrity protection, encoding, and decoding operations through configuration, thereby achieving efficient transmission of data.

[0139] The following will, with reference to the accompanying drawings, describe in detail the method for transmitting a target service provided by the embodiments of the present application through some embodiments and their application scenarios.

[0140] Figure 9 It is a schematic diagram of a method for transmitting a target service provided by an embodiment of the present application. As Figure 9 shown, the method 900 includes at least the following parts:

[0141] S910, the core network function sends first configuration information to the access network device, where the first configuration information is used to indicate the transmission channel configuration of the target service.

[0142] Correspondingly, the access network device receives the first configuration information from the core network function.

[0143] In some embodiments, the target service may be a service to be transmitted in a communication system. For example, it is a service requested to be collected by an Application Function (AF).

[0144] Exemplarily, the target service may include but is not limited to at least one of the following services:

[0145] Traditional services, such as File Transfer Protocol (FTP) downloads, video services, short messages, instant messaging services, etc.;

[0146] Traditional positioning services;

[0147] Data plane services.

[0148] In some embodiments, data plane services (or data plane data) may refer to data generated or consumed by intelligence, perception, or network operation, etc. Such data needs to be collected, preprocessed, stored, and analyzed in a distributed manner.

[0149] Exemplarily, the data plane service may include but is not limited to at least one of the following:

[0150] Services related to AI, communication and sensing services (or perception services), data plane services related to positioning (such as LPP services), network adaptive optimization services, Self-Organizing Network (SON) services, Minimization of Drive Test (MDT) services.

[0151] For the convenience of distinction and description, the core network function that sends the first configuration information is denoted as the first core network function.

[0152] Exemplarily, the first core network function may be the AMF, or it may also be other core network functions. In the following specific examples, the first core network function is taken as the AMF as an example, but the present application is not limited thereto.

[0153] In the embodiments of the present application, the processing of data plane services can be implemented through the first network node.

[0154] In some embodiments, the first network node may be deployed on the core network side.

[0155] For example, the first network node may be an independent core network function entity, or a Data Control Function (DCF), a Data Plane Adaptation Protocol (DPAP) function, a data plane processing function, a data plane function, etc. The present application does not limit this. Or, a data plane processing module may also be added to the existing core network function to implement the processing of data plane services. For example, the processing of data plane services is implemented through the SMF. The present application does not limit this.

[0156] Again, for example, the first network node may also be deployed on the access network side.

[0157] Specifically, for example, a data plane processing module is added to the access network device to implement the processing of data services, or the first network node may also be a direct connection node of the access network device. In this way, direct communication can be carried out between the first network node and the access network device, without being limited to the participation of the core network function.

[0158] Hereinafter, the first network node is taken as the DCF as an example for description, but the present application is not limited thereto.

[0159] In some embodiments, the first network node includes a first data plane function protocol layer for implementing the processing and / or transmission of data plane data.

[0160] It should be understood that the name of the first data plane function protocol layer is only an example and may also be replaced by other names, such as the DCF layer, the DPAP layer, etc. The present application does not limit this.

[0161] In some embodiments, the transmission channel configuration of the target service can be used to configure the routing nodes (or, the transmission mode) included in the transmission channel of the target service, and the processing mode of the target service in the transmission channel, for example, whether to perform transparent transmission or whether to process the target service. Specifically, for example, whether encryption is required, whether integrity protection is performed, whether encoding is performed, etc.

[0162] In some embodiments, the transmission channel configuration of the target service is used to indicate but is not limited to at least one of the following:

[0163] Whether the access network device needs to process the target service;

[0164] Whether to encrypt the target service;

[0165] Whether to perform integrity protection on the target service;

[0166] Whether to encode the target service;

[0167] The encryption algorithm used to encrypt the target service;

[0168] The encoding algorithm used to encode the target service;

[0169] The transmission mode of the target service, or rather, the routing nodes included in the transmission channel of the target service.

[0170] In some embodiments, whether the access network device needs to process the target service may include whether the access network device needs to perform encryption, integrity protection, and encoding processing on the target service.

[0171] In some embodiments, the transmission mode of the target service is used to indicate at least one of the following:

[0172] Transmission through the control plane, denoted as transmission mode 1;

[0173] Transmission through the user plane, denoted as transmission mode 2;

[0174] Only transmission through the control plane between the core network function and the access network device, denoted as transmission mode 3;

[0175] Only transmission through the data plane between the core network function and the access network device, denoted as transmission mode 4;

[0176] Only transmission through the control plane between the terminal and the access network device, denoted as transmission mode 5;

[0177] Only transmission through the data plane between the terminal and the access network device, denoted as transmission mode 6.

[0178] In some embodiments, for transmission mode 1, it can be considered that the routing nodes included in the transmission path of the target service are the terminal, the access network device, and the AMF.

[0179] In some embodiments, for transmission mode 2, it can be considered that the routing nodes included in the transmission path of the target service are the terminal, the access network device, and the UPF.

[0180] In some embodiments, for transmission mode 3, it can be considered that the routing nodes included in the transmission path of the target service are the access network device and the AMF.

[0181] In some embodiments, for transmission mode 4, it can be considered that the routing nodes included in the transmission path of the target service are the access network device and the first network node, such as the DCF. For example, the target service can be transmitted through the first data plane function protocol layer of the access network device and the first network node.

[0182] In some embodiments, for transmission mode 5, it can be considered that the routing nodes included in the transmission path of the target service are the terminal and the access network device.

[0183] In some embodiments, for transmission mode 6, it can be considered that the routing nodes included in the transmission path of the target service are the terminal and the access network device. For example, the target service is a data plane service, and the target service is transmitted through the first sublayer of the access network device and the first sublayer of the terminal.

[0184] In some embodiments, the access network device can process and / or transmit the target service according to the first configuration information.

[0185] For example, when the first configuration information indicates that the target service is not to be processed, the access network device can consider that the target service is not encrypted and integrity protected. Therefore, the access network device can not decrypt the target service and verify its integrity, that is, perform transparent transmission of the target service, which is beneficial to improving the processing efficiency of the target service.

[0186] Again, for example, when the first configuration information indicates that the target service is not to be encrypted, the access network device can consider that the target service is not encrypted but integrity protected. Therefore, the access network device can not decrypt the target service but verify its integrity, which is beneficial to improving the processing efficiency of the target service.

[0187] Once again, for example, when the first configuration information indicates that the target service is not to be integrity protected, the access network device can consider that the target service is not integrity protected but encrypted. Therefore, the access network device can not verify the integrity of the target service but decrypt the target service, which is beneficial to improving the processing efficiency of the target service.

[0188] Another example is that when the first configuration information indicates that the target service is to be transmitted through the user plane, the access network device can transmit the target service to the AMF. Or, when the first configuration information indicates that the target service is to be transmitted through the control plane, the access network device can transmit the target service to the UPF. Or, when the first configuration information indicates that the target service is to be transmitted through the data plane between the core network function and the access network device, the access network device can transmit the target service to the DCF.

[0189] In some embodiments, if the first configuration information does not indicate whether to encrypt the target service, it is default to encrypt the target service, or, alternatively, it may be default not to encrypt the target service; or, if the first configuration information does not indicate whether to perform integrity protection on the target service, it is default to perform integrity protection on the target service, or, alternatively, it may be default not to perform integrity protection on the target service; or, if the first configuration information does not indicate whether to encode the target service, it is default to encode the target service, or, alternatively, it may be default not to encode the target service; or, if the first configuration information does not indicate the encoding algorithm used to encode the target service, a default encoding algorithm may be adopted.

[0190] Therefore, in the embodiments of the present application, the core network function configures the transmission channel of the target service by instructing the access network device, so that the access network device can process and / or transmit the target service according to the transmission channel configuration, which is beneficial to realizing the efficient transmission of the target service.

[0191] In some embodiments, the first configuration information is determined according to the characteristics of the target service.

[0192] Exemplarily, the characteristics of the target service include at least one of the following:

[0193] The size (or, data length) of the target service;

[0194] The reporting period of the target service;

[0195] The service type of the target service;

[0196] The data security sensitivity of the target service;

[0197] The processing method indication of the target service, and the processing method indication is used to indicate whether the access network device needs to process the target service.

[0198] Therefore, in the embodiments of the present application, by indicating a suitable transmission channel configuration for the target service according to the characteristics of the target service, and then processing and / or transmitting the target service based on the transmission channel configuration, it is beneficial to balance the transmission reliability and transmission efficiency of the target service.

[0199] In some embodiments, the data security sensitivity of the target service may include sensitive and insensitive, or, alternatively, it may be divided into more sensitivity levels, such as not requiring confidentiality (i.e., insensitive), partially confidential, and fully confidential, etc.

[0200] Exemplarily, if the data security sensitivity of the target service is insensitive, the first configuration information may indicate that encryption and integrity protection are not required (or, in other words, no processing is required), or, if the data security sensitivity of the target service is sensitive, the first configuration information may indicate that encryption and integrity protection are required.

[0201] In some embodiments, the data length of the target service may be divided into multiple ranges, such as a first range and a second range. The data length in the first range is shorter, and the data length in the second range is longer. If the data length of the target service falls within the first range, the target service may not be compressed. In this case, the first configuration information may indicate an encoding algorithm that does not compress and has a fast processing time. Or, if the data length of the target service falls within the second range, the first configuration information may be used to indicate that compression encoding is required, and may also indicate a specific compression encoding algorithm.

[0202] In some embodiments, if the processing mode of the target service indicates that the access network device needs to process the target service, the first configuration information may indicate that encryption and integrity protection are required. Or, if it is indicated that the access network device does not need to process the target service, the first configuration information may indicate that encryption and integrity protection are not required.

[0203] In some embodiments, the transmission mode of the target service and / or the bearer used to transmit the target service may be determined according to the reporting period of the target service. For example, whether to use the user plane transmission or the control plane transmission, and whether to use a dedicated bearer or a general bearer for transmitting the target service. Exemplarily, if the reporting period of the target service is short, indicating that the target service is reported frequently, user plane transmission may be used, or a dedicated bearer transmission may also be used. Exemplarily, if the reporting period of the target service is long, indicating that the data plane reporting is not frequent, and if the data volume of the target service is small, in this case, control plane transmission may be used, or it may be transmitted through the Small Data Transmission (SDT) process.

[0204] In some embodiments, the characteristics of the target service may be obtained by the first core network function from the second core network function.

[0205] In some embodiments, before S910, the method 900 further includes:

[0206] The first core network function receives the characteristics of the target service from the second core network function.

[0207] In some embodiments, the second core network function may be SMF, DCF, LMF, etc.

[0208] For example, if the target service is a traditional service or a traditional positioning service, the second core network function may be the SMF.

[0209] For another example, if the target service is a data plane service not related to positioning, the second core network function may be the DCF.

[0210] For still another example, if the target service is a data plane service related to positioning, the second core network function may be the LMF.

[0211] In some embodiments, the second core network function may send the characteristics of the target service to the first core network function based on a first request, where the first request is used to request the transmission of the target service, and the characteristics of the target service to be transmitted are included in the first request.

[0212] For example, the second core network function receives the first request from the AF, where the characteristics of the target service to be transmitted are included in the first request. After receiving the first request, the second core network function may send the characteristics of the requested target service to the first core network function. The first core network function may determine the first configuration information based on the characteristics of the data plane data.

[0213] Exemplarily, the AF may send a first request to the SMF for requesting the transmission of a traditional service or a traditional positioning service, where the characteristics of the requested service are included in the first request, and the SMF may send the characteristics of the requested service to the first core network function.

[0214] Exemplarily, the AF may send a first request to the DCF for requesting the transmission of a data plane service, where the characteristics of the requested data plane service are included in the first request, and the DCF may send the characteristics of the requested data plane service to the first core network function.

[0215] Exemplarily, the AF may send a first request to the LMF for requesting the transmission of a data plane service related to positioning, where the characteristics of the requested data plane service related to positioning are included in the first request, and the LMF may send the characteristics of the requested data plane service related to positioning to the first core network function.

[0216] In the embodiments of the present application, the first request, also known as a service request or a service request, when the requested service is a data plane service, the first request, also known as a data plane service request or a data plane service request.

[0217] In some embodiments, a service request may correspond to a Protocol Data Unit (PDU) session identifier (PDU Session ID). For example, a PDU session is established based on a service request for transmitting the target service of the request. Alternatively, an existing PDU session may be modified to meet the requirements of the target service.

[0218] In some embodiments, the first core network function may establish an association relationship between the second core network function (such as SMF, DCF, or LMF, etc.) and the PDU Session ID, for example, establish an association relationship between the PDU Session ID and the IP address or ID of the second core network function.

[0219] In some embodiments of the present application, the first configuration information further includes but is not limited to at least one of the following:

[0220] PDU Session ID;

[0221] PDU address (PDUAddress);

[0222] PDU session type (PDU Session Type), or NAS PDU Session Type;

[0223] Quality of Service (QoS) flow identifier (QoS Flow Identifier);

[0224] QoS profile;

[0225] Additional QoS characteristics;

[0226] The IP address of the target network node for processing the target service;

[0227] The identification information (ID) of the target network node;

[0228] The tunnel endpoint identifier (TEID) of the target service;

[0229] The transaction identifier (TI) of the target service;

[0230] The maximum number of bearers supported by the target service;

[0231] The service type of the target service.

[0232] In some embodiments, if the target service is a data plane service, the target network node may be the aforementioned first network node, such as a DCF. Alternatively, if the target service is not a data plane service, the target network node may be an AMF or a UPF, etc.

[0233] In some embodiments, the PDU session identified by the PDU Session ID in the first configuration information may be a PDU session available for transmitting the target service, or in other words, a PDU session that meets the transmission requirements of the target service. Therefore, the target service can be transmitted based on the PDU session corresponding to the PDU Session ID, which is beneficial to meeting the transmission requirements of the target service.

[0234] In some embodiments, the PDU Address can be used to determine the PDU session available for transmitting the target service, or in other words, the PDU session that meets the transmission requirements of the target service. Therefore, transmitting the target service based on the PDU session corresponding to the PDU Address is beneficial to meeting the transmission requirements of the target service.

[0235] In some embodiments, the PDU Session Type may be the type of PDU session available for transmitting the target service. Therefore, the target service can be transmitted based on the PDU session of the PDU Session Type, which is beneficial to meeting the transmission requirements of the target service;

[0236] In some embodiments, the QoS Flow Identifier can be used to indicate the QoS Flow available for transmitting the target service. Therefore, transmitting the target service based on the QoS Flow identified by the QoS Flow Identifier is beneficial to meeting the QoS requirements of the target service.

[0237] In some embodiments, the QoS profile can be used to determine the QoS Flow available for transmitting the target service. Therefore, an appropriate QoS Flow can be selected based on the QoS profile for transmitting the target service, which is beneficial to meeting the QoS requirements of the target service.

[0238] In some embodiments, the additional QoS features may include, but are not limited to, at least one of the following:

[0239] Bandwidth management: Provide different bandwidth allocations for different applications or data streams to ensure higher priority for data transmission of important applications;

[0240] Latency guarantee: Minimize the latency time of data transmission to ensure accurate and smooth transmission of real-time data;

[0241] Bandwidth guarantee: Provide sufficient bandwidth for important applications or data streams to ensure their normal operation without interference from other applications in the network;

[0242] Traffic control: Control the amount of traffic entering the network to avoid network overload, thereby improving network performance and reliability;

[0243] Congestion control: Detect network congestion in a timely manner and take measures to avoid or alleviate congestion, thereby ensuring network communication quality;

[0244] Priority sorting: Set priority sorting to ensure that more important data transmissions in the network receive higher priorities, thereby realizing intelligent management of the network;

[0245] Fault recovery: Detect and repair network faults in a timely manner to ensure network reliability and uninterruptibility.

[0246] In some embodiments, an appropriate QoS Flow can be selected based on this additional QoS feature for transmitting the target service, which is beneficial to meeting the additional QoS feature of the target service.

[0247] In some embodiments, the IP address of the target network node can determine which network node to forward the target service to, so as to facilitate the target network node to process the target service. For example, if the target service is a data plane service, the IP address of the target network node can be the IP address of the first network node (such as DCF).

[0248] In some embodiments, the ID of the target network node can determine which network node to forward the target service to, so as to facilitate the network node to process the target service. For example, if the target service is a data plane service, the identification information of the target network node can be the identification information of the first network node (such as DCF).

[0249] In some embodiments, the TEID of the target service can also be used to determine which network node to forward the data plane service to, so as to facilitate the target network node to process the target service.

[0250] For example, if there is an association relationship between the TEID of the target service and the IP address or ID of the target network node, then which network node to forward the target service to can be determined according to the TEID of the target service and this association relationship.

[0251] In some embodiments, the maximum number of bearers supported by the target service can be understood as the maximum number of bearers through which the target service can be transmitted at most.

[0252] In some embodiments, the service type of the target service can include, for example, but is not limited to at least one of the following:

[0253] Traditional services (such as video services, short message services, instant messaging services, etc.), traditional positioning services, data plane services. For example, it can further indicate the type of specific data plane services, such as services related to AI, communication sensing services, positioning-related data plane services (such as LPP services), network self-adaptive optimization services, SON services, MDT services, etc.

[0254] Optionally, an appropriate PDU session, QoS flow, bearer, etc. can be selected according to the service type of the target service to meet the transmission requirements of this type of service.

[0255] In the embodiments of the present application, the first configuration information can be used to determine at least one of the following:

[0256] The PDU session, QoS flow, bearer configuration for transmitting the target service, and the target receiving device (i.e., the target network node) of the target service.

[0257] It should be understood that the first configuration information can be sent through the existing signaling between the first core network function and the access network device, or alternatively, new signaling can be dedicated to sending the first configuration information. The present application does not make any limitations in this regard.

[0258] It should also be understood that the transmission channel configuration of the target service and other configuration information in the first configuration information can be sent through one signaling, or alternatively, through different signaling. The present application does not make any limitations in this regard.

[0259] In some embodiments, the first configuration information can be sent through NAS signaling, such as NAS PDU signaling.

[0260] Exemplarily, the first configuration information can be sent through at least one of the following signaling:

[0261] PDU session resource establishment request (PDU SESSION RESOURCE SETUP REQUEST);

[0262] PDU session resource modification request (PDU SESSION RESOURCE MODIFICATION REQUEST);

[0263] The first transmission request for requesting the transmission of the target service.

[0264] In some embodiments, the first transmission request can be a newly added message, or rather, a newly added interface for requesting the transmission of the target service. For example, the first transmission request can be a newly added control plane interface, or a newly added user plane interface, etc.

[0265] Optionally, when the first transmission request is used to request the transmission of the target service through the data plane, the first transmission request, or the data plane data transfer request (DATA PLANE DATA TRANSFER REQUEST), or, it can also have other names, and this application does not make any limitations in this regard.

[0266] Optionally, when the first transmission request is used to request the transmission of the target service through the control plane, the first transmission request, or the control plane data transfer request (CONTROL PLANE DATA TRANSFER REQUEST), or, it can also have other names, and this application does not make any limitations in this regard.

[0267] Optionally, when the first transmission request is used to request the transmission of the target service through the user plane, the first transmission request, or the user plane data transfer request (USER PLANE DATA TRANSFER REQUEST), or, it can also have other names, and this application does not make any limitations in this regard.

[0268] It should be noted that in the embodiments of this application, the first core network function can explicitly indicate the transmission channel configuration of the target service to the access network device, or, it can also implicitly indicate the transmission channel configuration of the target service, and this application does not make any limitations in this regard.

[0269] In some implementation manners, the first configuration information includes a configuration identifier (or configuration index), and this configuration identifier is used to identify the transmission channel configuration of the target service.

[0270] For example, the configuration identifier corresponds to a group of transmission channel configurations in the transmission channel configuration table, where the transmission channel configuration table includes at least one group of transmission channel configurations.

[0271] Optionally, the transmission channel configuration table is predefined (i.e., stipulated by the protocol), or pre-configured. For example, the transmission channel configuration table is pre-configured on the access network device and the first core network function. When it is necessary to indicate the transmission channel configuration to the access network device, the first core network function determines the configuration identifier corresponding to the target transmission channel configuration that needs to be indicated to the access network device in the transmission channel configuration table, and further sends this configuration identifier to the access network device.

[0272] In other implementation manners, the first configuration information explicitly includes the specific transmission channel configuration.

[0273] In some embodiments of this application, as Figure 9 shown, the method 900 further includes:

[0274] S920, the core network function sends second configuration information to the terminal, and the second configuration information is used to indicate the non-access stratum (NAS) layer configuration of the target service.

[0275] Correspondingly, the terminal receives the second configuration information from the core network function.

[0276] In some embodiments, the second configuration information may be sent through the existing signaling between the first core network function and the terminal, or alternatively, new signaling may be dedicated to sending the second configuration information, and the present application does not make any limitation in this regard.

[0277] Exemplarily, the second configuration information may be sent through NAS signaling.

[0278] In some embodiments, the second configuration information is used to indicate but is not limited to at least one of the following:

[0279] Whether to process the target service at the NAS layer;

[0280] Whether to encrypt the target service at the NAS layer;

[0281] Whether to perform integrity protection on the target service at the NAS layer;

[0282] Whether to encode the target service at the NAS layer;

[0283] The encryption algorithm used to encrypt the target service at the NAS layer;

[0284] The encoding algorithm used to encode the target service at the NAS layer.

[0285] In some embodiments, the terminal may process the target service according to the second configuration information. For example, if the second configuration information indicates that the terminal does not process the target service at the NAS layer, or if the second configuration information indicates that the terminal does not encrypt the target service at the NAS layer, the terminal may not encrypt the target service, or if the second configuration information indicates that the terminal does not perform integrity protection on the target service at the NAS layer, the terminal may not perform integrity protection on the target service.

[0286] In some embodiments, if the second configuration information does not indicate whether to encrypt the target service at the NAS layer, by default, the target service is encrypted at the NAS layer, or by default, the target service is not encrypted at the NAS layer; or, if the second configuration information does not indicate whether to perform integrity protection on the target service at the NAS layer, by default, integrity protection is performed on the target service at the NAS layer, or by default, integrity protection is not performed on the target service at the NAS layer at the NAS layer; or, if the second configuration information does not indicate whether to encode the target service at the NAS layer, by default, the target service is encoded at the NAS layer, or by default, the target service is not encoded at the NAS layer; or, if the first configuration information does not indicate the encoding algorithm used to encode the target service, a default encoding algorithm may be used, or if the first configuration information does not indicate the encryption algorithm used to encrypt the target service, a default encryption algorithm may be used.

[0287] In some embodiments, the second configuration information may be configured for each terminal, that is, the same NAS layer configuration is adopted for all services of the terminal, or it may also be configured for each service. For example, different services may correspond to different NAS layer configurations.

[0288] In some embodiments, the access network device may determine whether to establish a new bearer for transmitting the target service according to the first configuration information, or reconfigure an existing bearer to meet the transmission channel configuration of the target service.

[0289] For example, if the first configuration information indicates that the access network device does not need to process the target service, and the configuration of the existing bearer is to process the target service, the access network device may establish a new bearer, or it may also modify the bearer configuration of the existing bearer to not process the target service.

[0290] In some embodiments of the present application, as Figure 9 shown, the method 900 further includes:

[0291] S930, the access network device sends the third configuration information to the terminal, and the third configuration information is used to indicate the bearer configuration of the target service.

[0292] Correspondingly, the terminal receives the third configuration information from the access network device.

[0293] Optionally, when the target service is only transmitted between the core network function and the access network device (such as the aforementioned transmission modes 3 and 4), the method 900 may not include this step S930. Or, when the access network device determines to use the existing bearer to transmit the target service, the method 900 may also not include S930.

[0294] In some embodiments, the third configuration information includes at least one of the following:

[0295] The first indication information, which is used to indicate the establishment of a target signaling radio bearer (SRB);

[0296] The configuration information of the target SRB;

[0297] The second indication information, which is used to indicate the establishment of a target data radio bearer (DRB);

[0298] The configuration information of the target DRB;

[0299] The third indication information, which is used to indicate the establishment of a target radio bearer (RB) for carrying target services;

[0300] The configuration information of the target RB.

[0301] In some embodiments, the target service is a data-plane service. The target SRB can be an SRB dedicated to the data-plane service, and the target DRB is a DRB dedicated to the data-plane service.

[0302] In some embodiments, the target service is a data-plane service. The target RB can be a dedicated RB for the data-plane service. For example, the target RB can be a special DRB, or it can also be a new RB type dedicated to the transmission of the target service, such as a DPRB.

[0303] In some embodiments, the target SRB is associated with (or mapped to) a first PDU session, and the first PDU session is the first PDU session indicated in the first configuration information. For example, the target SRB is the only SRB associated with the first PDU session.

[0304] In some embodiments, the target DRB is associated with (or mapped to) a first PDU session, and the first PDU session is the first PDU session indicated in the first configuration information. For example, the target DRB is the only DRB associated with the first PDU session.

[0305] In some embodiments, the target RB is associated with (or mapped to) a first PDU session, and the first PDU session is the first PDU session indicated in the first configuration information. For example, the target RB is the only RB associated with the first PDU session.

[0306] It should be understood that the third configuration information can be sent through existing signaling between the access network device and the terminal, or new signaling can be added specifically for sending the third configuration information. This application does not make any limitations in this regard.

[0307] Exemplarily, the third configuration information is sent via RRC signaling, such as RRC Setup signaling or RRC Reconfiguration signaling, etc.

[0308] For example, when the access network device determines to establish a new bearer to transmit the target service, the third configuration information can be carried by the RRC Setup signaling. Or, when the access network device determines to reconfigure an existing bearer to transmit the target service, the third configuration information can be carried by the RRC Reconfiguration signaling.

[0309] It should be understood that in the embodiments of the present application, the access network device can explicitly indicate the bearer configuration to the terminal, or can also implicitly indicate the bearer configuration, and the present application does not make a limitation thereon.

[0310] In some implementation manners, the third configuration information includes a configuration identifier (or referred to as a configuration index), and this configuration identifier is used to identify the bearer configuration.

[0311] For example, the configuration identifier corresponds to a group of bearer configurations in the bearer configuration table, where the bearer configuration table includes at least one group of bearer configurations.

[0312] Optionally, the bearer configuration table is predefined (i.e., stipulated by the protocol), or pre-configured. For example, the bearer configuration table is pre-configured on the access network device and the terminal. When it is necessary to indicate the bearer configuration to the terminal, the access network device determines the configuration identifier corresponding to the target bearer configuration that needs to be indicated to the terminal in the bearer configuration table, and further sends this configuration identifier to the terminal.

[0313] In some other implementation manners, the third configuration information explicitly includes specific bearer configurations.

[0314] In some embodiments, the configuration information of the target SRB is used to indicate the processing manner of the target service at at least one layer of the target SRB. For example, the configuration information of the target SRB is used to indicate at least one of the following:

[0315] The identification information of the target SRB, such as the SRB ID;

[0316] Whether to encrypt the target service at the PDCP layer of the target SRB;

[0317] Whether to perform integrity protection on the target service at the PDCP layer of the target SRB;

[0318] The encryption algorithm used to encrypt the target service at the PDCP layer of the target SRB;

[0319] Whether to encode the target service at the RRC layer of the target SRB;

[0320] Whether to encode the target service.

[0321] Exemplarily, when using an existing SRB to transmit the target service, that is, when neither a new SRB needs to be established nor the existing SRB needs to be reconfigured, the configuration information of the target SRB may only include the identification information of the target SRB, which is used to indicate the SRB for transmitting the target service. In this case, there is no need to modify the configuration of the target SRB.

[0322] Exemplarily, when modifying an existing SRB to transmit the target service, the existing SRB can be reconfigured. In this case, the configuration information of the target SRB may include the identification information of the target SRB and the SRB configuration that needs to be modified. For example, if the PDCP layer of the target SRB encrypts the target service and it is determined according to the first configuration information that it needs to be modified to not encrypt the target service in the PDCP layer, the configuration information of the target SRB can indicate that the target service does not need to be encrypted in the PDCP layer of the target SRB.

[0323] Exemplarily, when establishing a new SRB to transmit the target service, the configuration information of the target SRB may include the identification information of the target SRB and the configuration information of the new SRB, which is used to indicate the processing method of the target service in each layer of the SRB.

[0324] In some embodiments, the configuration information of the target DRB is used to indicate the processing method of the target service in at least one layer of the target DRB. For example, the configuration information of the target DRB is used to indicate at least one of the following:

[0325] The identification information of the target DRB, such as DRB ID;

[0326] Whether to encrypt the target service in the PDCP layer of the target DRB;

[0327] Whether to perform integrity protection on the target service in the PDCP layer of the target DRB;

[0328] The encryption algorithm used to encrypt the target service in the PDCP layer of the target DRB;

[0329] Whether to encode the target service in the RRC layer of the target DRB;

[0330] Whether to encode the target service.

[0331] Exemplarily, when using an existing DRB to transmit a target service, that is, when neither a new DRB needs to be established nor the existing DRB needs to be reconfigured, the configuration information of the target DRB may only include the identification information of the target DRB, which is used to indicate the DRB for transmitting the target service. In this case, no modification to the configuration of the target DRB is required.

[0332] Exemplarily, when modifying an existing DRB to transmit a target service, the existing DRB can be reconfigured. In this case, the configuration information of the target DRB may include the identification information of the target DRB and the DRB configuration that needs to be modified. For example, if the PDCP layer of the target DRB encrypts the target service and it is determined according to the first configuration information that the encryption should be modified to not encrypt the target service at the PDCP layer, the configuration information of the target DRB can indicate that the target service does not need to be encrypted at the PDCP layer of the target DRB.

[0333] Exemplarily, when establishing a new DRB to transmit a target service, the configuration information of the target DRB may include the identification information of the target DRB and the configuration information of the new DRB, which is used to indicate the processing method of the target service at each layer of the DRB.

[0334] In some embodiments, the configuration information of the target RB is used to indicate the processing method of the target service at at least one layer of the target RB. For example, the configuration information of the target RB is used to indicate at least one of the following:

[0335] The identification information of the target RB, such as the RB ID, specifically, for example, the DPRB ID;

[0336] Whether to encrypt the target service at the PDCP layer of the target RB;

[0337] Whether to perform integrity protection on the target service at the PDCP layer of the target RB;

[0338] The encryption algorithm used to encrypt the target service at the PDCP layer of the target RB;

[0339] Whether to encode the target service at the RRC layer of the target RB;

[0340] Whether to encode the target service.

[0341] Exemplarily, when using an existing RB to transmit a target service, that is, when neither a new RB needs to be established nor the existing RB needs to be reconfigured, the configuration information of the target RB may only include the identification information of the target RB, which is used to indicate the RB for transmitting the target service. In this case, no modification to the configuration of the target RB is required.

[0342] Exemplarily, when modifying the existing RB to transmit the target service, the existing RB can be reconfigured. In this case, the configuration information of the target RB can include the identification information of the target RB and the RB configuration to be modified. For example, if the PDCP layer of the target RB encrypts the target service and it is determined according to the first configuration information that the encryption of the target service in the PDCP layer needs to be modified, the configuration information of the target RB can indicate that the target service does not need to be encrypted in the PDCP layer of the target RB.

[0343] Exemplarily, when establishing a new RB (such as DPRB) to transmit the target service, the configuration information of the target RB can include the identification information of the target RB and the configuration information of the new RB, which is used to indicate the processing method of the target service in each layer of the RB.

[0344] In some embodiments, after obtaining the third configuration information, the access network device and the terminal can establish the target SRB according to the third configuration information, or modify the established SRB to meet the configuration indicated in the configuration information of the target SRB; or establish the target DRB, or modify the established DRB to meet the configuration indicated in the configuration information of the target DRB; or establish the target RB, or modify the established RB to meet the configuration indicated in the configuration information of the target RB.

[0345] In some embodiments, the access network device and the terminal can perform data transmission between the SDAP, PDCP, RLC, MAC, and PHY entities of the access network device and the terminal based on the target SRB, target DRB, or target RB, such as transmitting data plane services.

[0346] In some embodiments of the present application, for the terminal, one first request (indicated by the service ID) corresponds to one PDU Session ID, one PDU session ID can correspond to multiple RBs, and each RB corresponds to different QoS.

[0347] For the target network node, one first request corresponds to a unique IP address, and this IP address can be bound to multiple TEIDs. The services carrying different TEIDs come from different terminals, and the services of different TEIDs carried by different terminals are finally aggregated to the target network node.

[0348] In some embodiments of the present application, the method 900 further includes:

[0349] The terminal sends a second message to the access network device, and the second message includes the target service. Wherein, the target service is the service requested based on the first request.

[0350] Correspondingly, the access network device receives a second message from the terminal.

[0351] In some embodiments, the second message may be transmitted through the foregoing target SRB or target DRB or target RB.

[0352] In some embodiments, the access network device may determine the processing method and / or transmission method for the target service according to the first configuration information. For example, if the first configuration information indicates that the target service is not to be processed, the access network device may not perform decryption and integrity protection verification on the target service. Another example is that if the first configuration information indicates that the target service is to be transmitted through the user plane, the access network device may send the target service to the UPF. Or, if the first configuration information indicates that the target service is to be transmitted through the control plane, the access network device may send the target service to the AMF. Or, if the first configuration information is configured to transmit the target service through the data plane, the access network device may send the target service to the DCF.

[0353] In some embodiments, the access network device forwards the target service to a target network node according to the message type in the second message or the TEID in the second message, and the target network node is used for processing the target service.

[0354] In some embodiments, the target service is a data plane service, and the target network node may be the DCF, that is, the access network device may send the data plane service to the DCF. Optionally, if the data plane service is a positioning-related data plane service (for example, LPP service), the DCF may further send the data plane service to the LMF, and the LMF may decode the data plane service and send the decoded data plane service to the DCF.

[0355] In some embodiments, the DCF may obtain the identification information of the LMF from the first core network function.

[0356] For example, when the target service is a positioning-related data plane service, the first core network function may request the LMF to obtain the identification information of the LMF (for example, LMF ID), the LMF may send the identification information of the LMF (for example, LMF ID) to the first core network function, and the first core network function may send the identification information of the LMF (for example, LMF ID) to the DCF. In this way, when the DCF receives a positioning-related data plane service, it may forward the data plane service to the LMF, the LMF may decode the data plane service, and then receive the decoded data plane service from the LMF.

[0357] In some embodiments, the target service is a data plane service. The second message may be a message dedicated to transmitting data plane services, or alternatively, a message for transmitting user plane data or control plane data may be reused to transmit data plane services.

[0358] Exemplarily, the second message may be a GTP message. When the data plane service is transmitted through the user plane, the second message may be a GTP-U message.

[0359] In some embodiments, the message type in the second message may include at least one of the following:

[0360] Echo Request, Echo Response, data plane type (or, forwarding type), Error Indication, Supported Extension Headers Notification, Tunnel Status, End Marker, GTP-PDU (abbreviated as G-PDU).

[0361] In some embodiments, when the message type of the second message is the data plane type, the data plane service is forwarded to the target network node. For example, the target network node may be a DCF.

[0362] In other embodiments, when a second TEID is included in the second message and the second TEID is associated with the IP address or ID of the target network node, it is determined to forward the target service to the target network node. The association relationship between the TEID and the IP address or ID of the target network node may be pre-configured, for example, configured in a transmission channel configuration table, or alternatively, may be specified by a protocol.

[0363] In still other embodiments, the second message may also include the identification information or IP address of the target network node. Therefore, the access network device may also determine to forward the target service to the target network node based on the identification information or IP address of the target network node.

[0364] It should be understood that this application does not limit the execution order of the first configuration information and the second configuration information, and the second configuration information and the third configuration information. For example, the first configuration information and the second configuration information can be executed simultaneously, or the first configuration information can be sent first and then the second configuration information, or the second configuration information can be sent first and then the first configuration information. Another example is that the second configuration information and the third configuration information can be executed simultaneously, or the second configuration information can be sent first and then the third configuration information, or the third configuration information can be sent first and then the second configuration information.

[0365] In some embodiments of this application, the method 900 further includes:

[0366] The access network device sends a first message to the core network function (denoted as the third core network function), where the first message includes the target service. The target service is the service requested based on the first request.

[0367] Correspondingly, the third core network function receives the first message from the access network device.

[0368] In some embodiments, the third core network function forwards the target service to the target network node according to the message type (messagetype) in the first message or the TEID in the first message, where the target network node is used for processing the target service.

[0369] In some embodiments, the third core network function can be a core network node on the transmission channel of the target service. For example, if the target service is transmitted through the user plane, the third core network function can be a UPF; or if the target service is transmitted through the control plane, the third core network function can be an AMF; or if the target service is transmitted through the data plane, the third core network function can be a DCF.

[0370] For example, if the target service is a data plane service, the target network node can be a first network node, such as a DCF. That is, the third core network function can send the data plane service received from the access network device to the DCF. If the data plane service is a positioning-related data plane service (LPP service), the DCF can further send the data plane service to the LMF, and the LMF can decode the data plane service and send the decoded data plane service to the DCF.

[0371] In some embodiments, when the target service is a data plane service, the first message can be a message dedicated to transmitting the data plane service, or a message for transmitting user plane data or control plane data can be reused to transmit the data plane service.

[0372] Exemplarily, the first message may be a GTP message. When the data plane service is transmitted through the user plane, the first message may be a GTP-U message.

[0373] In some embodiments, the message type in the first message may include at least one of the following:

[0374] Echo Request, Echo Response, data plane type (or, forwarding type), Error Indication, Supported Extension Headers Notification, Tunnel Status, End Marker, GTP-PDU (abbreviated as G-PDU).

[0375] In some embodiments, when the message type of the first message is the data plane type, forward the data plane service to the target network node. For example, the target network node may be a DCF.

[0376] In some other embodiments, when a first TEID is included in the first message and the first TEID is associated with the IP address or ID of the target network node, it is determined to forward the target service to the target network node. Among them, the association relationship between the TEID and the IP address or ID of the target network node may be pre-configured, such as configured in a transmission channel configuration table, or may also be stipulated by the protocol.

[0377] In still some other embodiments, the identification information or IP address of the target network node may also be included in the first message. Therefore, the third core network function may determine to forward the target service to the target network node according to the identification information or IP address of the target network node.

[0378] In some embodiments, when the target service is a data plane service and the access network device supports processing the data plane service (for example, a data plane processing module is deployed in the access network device), the access network device may not forward the data plane service and directly process the data plane service.

[0379] In some embodiments, when the target service is a data plane service and the first network node (such as a DCF) is deployed on the access network side, for example, when the first network node is directly connected to the access network device, the access network device may directly send the data plane service to the first network node without the participation of the core network function.

[0380] Next, in combination with specific embodiments, the transmission scheme of the target service will be described.

[0381] Embodiment 1: User plane transmission solution, corresponding to the aforementioned transmission method 1

[0382] In this Embodiment 1, the target service is transmitted through the user plane, taking the first core network function as the AMF and the second core network function as the SMF as an example.

[0383] As Figure 10 shown, this user plane transmission solution may include the following steps:

[0384] S1001. The AF sends a first request to the SMF to request the target service. The first request may include the characteristics of the requested target service.

[0385] For example, the target service may be FTP download, video service, data plane service, etc.

[0386] In some embodiments, the characteristics of the requested target service include at least one of the following:

[0387] The size of the target service;

[0388] The reporting period of the target service;

[0389] The target service type;

[0390] The data security sensitivity of the target service;

[0391] The processing method indication of the target service, used to indicate whether the access network device needs to process the target service.

[0392] S1002. The SMF notifies the AMF to establish a PDU session according to the first request.

[0393] A PDU session 1 is established between the AMF and the terminal (for easy distinction, denoted as UE1) for transmitting the requested target service, and a PDUSession ID 1 is configured for this PDU session.

[0394] S1003. The AMF sends the first configuration information to the access network device according to the characteristics of the target service, for indicating the transmission channel configuration of the requested target service.

[0395] For example, the first configuration information is sent to the access network device through a PDU session resource establishment request (PDU SESSION RESOURCE SETUP REQUEST), or the first configuration information may also be sent through other messages in the foregoing embodiments, and this application is not limited thereto.

[0396] In this embodiment, the first configuration information is used to indicate the following configuration:

[0397] PDUSession ID 1;

[0398] The access network device does not need to process the target service;

[0399] The target service does not need to be encrypted;

[0400] TEID1;

[0401] Transmit the target service through the user plane.

[0402] S1004. The access network device sends the third configuration information to UE1 according to the first configuration information.

[0403] For example, send the third configuration information through an RRC reconfiguration message.

[0404] In this embodiment, the third configuration information is used to indicate the following configuration:

[0405] Transmit the service through DRB1, and DRB1 is associated with PDUSession ID 1;

[0406] Integrity protection is not required for the target service at the PDCP layer of DRB1;

[0407] Encryption is not required for the target service at the PDCP layer of DRB1.

[0408] S1005. UE1 generates the target service and processes the target service according to the third configuration information.

[0409] For example, UE1 delivers the target service to the SDAP layer of UE1. The SDAP layer of UE1 delivers the target service to the corresponding PDCP entity according to the PDU SessionID1. The PDCP entity of UE1 does not perform integrity protection and encryption on the target service and directly sends the target service to the RLC layer of UE1; the RLC layer of UE1 uses the transparent mode (TransparentMode, TM) to transmit the target service.

[0410] S1005. The access network device receives the target service sent by UE1 and processes the target service according to the third configuration information. For example, since the PDCP layer of UE1 does not perform integrity protection and encryption on the target service, the PDCP layer of the access network device does not perform integrity protection verification and decryption on the target service and directly forwards it to the UPF.

[0411] S1006. The UPF determines to forward the target service to the target network node according to the TEID in the message carrying the target service (corresponding to the first message in the foregoing text). For example, if the TEID in the first message is associated with the IP address or ID of the DCF, the target service is forwarded to the DCF.

[0412] In some embodiments, the AMF may establish multiple PDU sessions with multiple UEs and establish multiple GTP-U. When the service type is a data plane service, the target network node aggregates the service data of the data plane services collected from different UEs and sends it to the data requester, that is, the AF.

[0413] Embodiment 2: Control plane transmission scheme, corresponding to the foregoing transmission method 2

[0414] In this Embodiment 2, the target service is transmitted through the control plane, taking the first core network function as the AMF and the second core network function as the DCF or LMF as an example.

[0415] Such as Figure 11 As shown, this control plane transmission scheme may include the following steps:

[0416] S1101. The AF sends a first request to the DCF or LMF to request a data plane service. The first request may include the characteristics of the requested data plane service.

[0417] In some embodiments, the characteristics of the requested data plane service include at least one of the following:

[0418] The size of the data plane service;

[0419] The reporting period of the data plane service;

[0420] The data plane service type;

[0421] The data security sensitivity of the data plane service;

[0422] The processing method indication of the data plane service, which is used to indicate whether the access network device needs to process the data plane service.

[0423] In some embodiments, the data plane service requested by the AF from the LMF may be a positioning-related data plane service.

[0424] In some embodiments, the data plane service requested by the AF from the DCF may be a non-positioning-related data plane service, such as an AI-related service, a communication sensing service, a SON service, an MDT service, etc., or it may also be a positioning-related data plane service.

[0425] S1102. The DCF or LMF sends the characteristics of the data plane service to the AMF.

[0426] S1103. The AMF sends first configuration information to the access network device according to the characteristics of the data plane service, for indicating the transmission channel configuration of the requested data plane service.

[0427] For example, the first configuration information is sent by using an existing control plane message, or the existing control plane message is modified (such as modifying parameters) to send the first configuration information, or a new control plane message can also be added to send the first configuration information. For example, a new control plane data transfer request (CONTROL PLANE DATA TRANSFER REQUEST) is defined to carry the first configuration information. It should be understood that the name of this message is only an example and can also be replaced with other names, and this application is not limited thereto.

[0428] In this embodiment, the first configuration information is used to indicate the following configurations:

[0429] The access network device does not need to process the data plane service;

[0430] The data plane service does not need to be encrypted;

[0431] The data plane service is transmitted through the control plane.

[0432] S1104. The AMF sends second configuration information to the terminal, for indicating the NAS layer configuration of the data plane service.

[0433] For example, the second configuration information is used to indicate the following configurations:

[0434] The data plane service does not need to be encrypted at the NAS layer;

[0435] The data plane service does not need integrity protection at the NAS layer.

[0436] Exemplarily, the second configuration information is transmitted through NAS signaling.

[0437] Optionally, the second configuration information can be configured for the data plane service, that is, the second configuration information only applies to the data plane service, or configured for the terminal, that is, the second configuration information applies to all services of the terminal. For example, when the data plane service of this terminal is transmitted at the NAS layer, it does not need integrity protection and encryption, while when the data plane services of other terminals are transmitted at the NAS layer, integrity protection and encryption are still required.

[0438] S1105. The access network device sends third configuration information to the terminal according to the first configuration information.

[0439] For example, the third configuration information is sent through an RRC reconfiguration message.

[0440] In this embodiment, the third configuration information is used to indicate the following configuration:

[0441] Transmit data plane services through the target SRB (e.g., SRB2);

[0442] Integrity protection and encryption of the target service are not required for each layer of the target SRB.

[0443] S1106, UE1 generates data plane services and processes the data plane services according to the second configuration information and / or the third configuration information.

[0444] For example, the data plane service is an LPP service. The terminal can perform positioning measurements, and the generated LPP service can be transmitted through the LPP layer. For example, after being encoded (e.g., ASN.1 encoding) by the LPP layer of the terminal, it is delivered to the NAS layer of the terminal. The LPP service is not encrypted at the NAS layer of the terminal, and after being encoded, the LPP service is transmitted to the RRC layer of the terminal.

[0445] Another example is that the data plane service is not an LPP service. The terminal can perform data collection, generate the data plane service, then encode the data plane service (e.g., using PROTOBUF), and then deliver the encoded data plane service to the NAS layer of the terminal. The data plane service is not encrypted at the NAS layer of the terminal, and after being encoded at the NAS layer, it is delivered to the RRC layer of the terminal.

[0446] Further, the RRC layer of the terminal encodes the data plane service and delivers it to the PDCP layer. The PDCP layer does not perform integrity protection and encryption on the data plane service and directly sends it to the RLC layer of the terminal. Optionally, at the RLC layer, the terminal uses the TM mode for transmission.

[0447] S1107, the RLC layer of the terminal sends a second message to the access network device, and the second message includes the data plane service.

[0448] S1108, the access network device receives the second message and processes the data plane service according to the configuration indicated by the first configuration information. For example, the access network device does not perform integrity protection verification and decryption on the data plane service at the PDCP layer and transparently transmits the data plane service to the AMF.

[0449] S1109, the AMF receives a first message from the access network device, the first message includes the data plane service, and forwards the data plane service to the target network node.

[0450] In some embodiments, the AMP may determine which network node to forward the data plane service to according to the payload type in the first message. For example, the AMF parses the first message directly without decrypting it according to the first configuration information to obtain the payload type in the first message.

[0451] In some embodiments, the payload type in the first message may include at least one of the following:

[0452] N1 Session Management (SM) message;

[0453] Short Messaging Service (SMS)

[0454] LPP message container;

[0455] Support Optimal Route (SOR) transparent container;

[0456] UE policy container;

[0457] UE parameters update transparent container;

[0458] Location services message container

[0459] Cellular Internet of Things (CIoT) user data container;

[0460] Service-level-AA container;

[0461] Event notification;

[0462] Data transfer type or forwarding type;

[0463] Multiple payloads.

[0464] For example, when the paload type is an LPP message container, the paload in the first message is an LPP service.

[0465] For another example, when the paload type is a data plane service, the paload in the first message is a data plane service.

[0466] In this embodiment, the AMF sends the LPP service to the LMF, or the AMF sends the data plane service to the DCF.

[0467] It should be understood that the naming of the above paload type is only an example, and with the evolution of the standard, it can also be replaced by other names, and this application is not limited thereto.

[0468] In some embodiments, the AMP can determine which network node to forward the data plane service to according to the message type or TEID in the first message. The specific determination method refers to the relevant descriptions mentioned above. For the sake of brevity, it will not be elaborated here.

[0469] Embodiment 3: Through data plane transmission, corresponding to the foregoing transmission method 4

[0470] In this Embodiment 3, the first core network function may be the AMF, and the second core network function may be the DPAP entity.

[0471] Figure 12 Shows a protocol architecture diagram of a data plane provided by an embodiment of the present application, as Figure 12 shown, for data transmission on the data plane, a new protocol layer can be introduced, called the DPAP layer, or it can also be replaced by other names. This application does not make a limit thereto. The DPAP layer can be used to transmit data plane services (such as positioning services, sensing services, AI services, SON / MDT services, etc.), or it can also be used to generate data plane services. Such as signaling data on the data plane.

[0472] Next, in combination with Figure 13 , the data plane transmission solution provided by the embodiment of the present application will be described.

[0473] S1301, the AF sends a first request to the DPAP to request to collect data plane services, where the first request includes the characteristics of the data plane service. For example, the service type of the data plane service is positioning, the data period is fixed, the period is short, the data length is large, and the security sensitivity is that encryption is not required.

[0474] S1302, the DPAP notifies the AMF to start collecting positioning-related data plane services.

[0475] For example, the DPAP indicates at least one of the following to the AMF:

[0476] Features of the data plane service;

[0477] Service identifier of the data plane service, such as service ID 1;

[0478] Identification information of DPAP, such as DPAP ID1.

[0479] AMF establishes the first GTP connection, identified as: TEID1.

[0480] AMP can notify the access network device to establish the first PDU session, identified as: PDU session id 1.

[0481] S1303, AMF sends the first configuration information to the access network device.

[0482] For example, send the first configuration information through PDU SESSION RESOURCE SETUP REQUEST.

[0483] Exemplarily, the first configuration information can be used to indicate the following configurations:

[0484] PDU session id 1;

[0485] Configuration identification ID, corresponding to a set of transmission channel configurations in the transmission channel configuration list, where the transmission channel configuration indicates that integrity protection and encryption are not required;

[0486] DPAP ID 1, corresponding to the ID of the aforementioned target network node;

[0487] TEID1, which is associated with DPAP ID1 or the IP address of the DPAP entity;

[0488] Transmitted through the data plane.

[0489] S1304, the access network device sends the third configuration information to the terminal according to the first configuration information.

[0490] For example, send the third configuration information through the RRC reconfiguration message.

[0491] Exemplarily, the third configuration information is used to indicate the following configurations:

[0492] Establish DRB;

[0493] No integrity protection and encryption are performed at the PDCP layer of the DRB.

[0494] S1305, the terminal generates a positioning service and processes the positioning service according to the third configuration information.

[0495] For example, the terminal can perform positioning measurements to generate a positioning service, and further transmit it to the access network device through the SDAP layer, PDCP layer, RLC layer, MAC layer, and PHY layer. Among them, at the PDCP layer, the terminal does not perform integrity protection and encryption on the positioning service.

[0496] S1306. The access network device receives a message carrying the positioning service (corresponding to the second message in the previous text), and does not perform integrity protection verification and decryption on the second message according to the third configuration information.

[0497] In some embodiments, the access network device can determine which network node to forward the positioning service to according to the message type of the second message or the TEID in the second message.

[0498] For example, the second message can be a GPT-U message. When the message type in the message header of the GPT-U message is a data plane type or a positioning-related type, the access network device can send the positioning service to the DPAP entity according to the DPAP ID1 in the first configuration information.

[0499] S1307. The access network device sends the positioning service to the DPAP entity.

[0500] In some embodiments, the DPAP can also indicate at least one of the following to the AMF based on the second request of the AF, where the second request is used to request the transmission of a data plane service:

[0501] The characteristics of the data plane service;

[0502] The service identifier of the data plane service, such as service ID 1;

[0503] The identification information of the DPAP, such as DPAP ID1.

[0504] Based on the above information, the AMF can also establish a second GTP connection, identified as TEID2, and establish a second PDU session, identified as: PDU sessionID2. And notify the TEID2 and PDU sessionID2 to the access network device.
