[0106] The term "and / or" in the embodiments of the present disclosure describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the front and rear associated objects. The term "multiple" in the embodiments of the present disclosure means two or more, and other quantifiers are similar.

[0107] With reference to the drawings of the embodiments of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present disclosure.

[0108] With the continuous development of communication technology, 6G network faces the double driving force of business scenarios and technology development. The architecture of 6G network needs to consider distributed architecture, and the control plane is gradually evolving towards distribution. With the distribution of intelligence and the distributed development of cloud computing, new connections and new networks will also move towards distribution.

[0109] The sixth generation mobile communication technology (6th generation mobile networks, 6G) will face the multi-scene and network demand of air, sky, land and sea. The centralized network architecture cannot meet all scenarios. To meet this challenge, the 6G network architecture needs to go beyond centralized control and gradually evolve towards distributed architecture, expand more network functions (such as authentication and authorization) to the network edge, and establish distributed isomorphic micro cloud units with different function levels. Each micro cloud unit is self-contained and has complete control and data forwarding functions. Multiple micro cloud units can form an autonomous micro network according to business needs, and provide network services according to specific business scenarios, user scale, geographical environment, etc. Among them, the above micro cloud units are also called distributed network nodes, representing a customized or fully functional core network on demand.

[0110] However, the inventors have found that in addition to user connection data, 6G networks also derive other new types of data, such as perception data, artificial intelligence (AI) data, computing power data, etc. These new types of data have changed in quality and quantity compared to the current user equipment (UE) connection data, such as data type, data size, topology relationship between data sources, and data consumption objects, etc. The current method of establishing an end-to-end user plane channel for UE through a protocol data unit (PDU) session is used to transmit UE single, point-to-point, end-to-end data. Based on the current data transmission mechanism and the capability of the user plane function (UPF) network element itself, it cannot meet the on-the-fly computing, multi-modal data transmission, and arbitrary topology transmission of 6G new data (perception, AI, computing, etc.). Therefore, how to transmit new types of data or process related services of new types of data based on the UPF network element is a problem that needs to be solved urgently.

[0111] FIG. 1 is an architecture diagram of a protocol stack and interfaces of a UPF network element provided by an embodiment of the present disclosure. As shown in FIG. 1, the architecture includes a UE, a network device, and a UPF network element.

[0112] The UE is configured to send service data to the network device, and the network device is configured to forward the service data sent by the UE to the UPF network element through an N3 interface.

[0113] The N3 interface is an interface between an NG RAN and the UPF network element, and the UPF network element uses a GTP-U protocol for tunneling transmission of user data.

[0114] The UPF network element is configured to forward service data sent by the network device to a data network (DN) through an N6 interface.

[0115] In some scenarios, multiple UPF network elements are connected to each other through an N9 interface.

[0116] It should be noted that the UPF network element is an important component of the 3GPP 5G core network architecture, and is mainly responsible for functions related to routing and forwarding of 5G core network user plane data packets. The UPF network element plays an important role in 5G edge computing and network slicing technologies that are oriented towards low latency and large bandwidth.

[0117] The UPF network element mainly supports routing and forwarding of UE service data, data and service identification, action and policy execution, and the like. The UPF network element interacts with a session management function (SMF network element) SMF network element through an N4 interface, directly receives control and management of the SMF network element, and performs processing of service flows according to various policies issued by the SMF network element.

[0118] The main functions of the UPF network element include, but are not limited to, the following:

[0119] 1) an interconnection point between a wireless access network and a data network, used for encapsulation and decapsulation of a GTP tunneling protocol (GPRS Tunneling Protocol for User Plane, GTP-U) for a user plane;

[0120] 2) a protocol data unit session anchor point (PDU Session Anchor, PSA), used for providing mobility during wireless access;

[0121] 3) Routing and local breakout of 5G standalone (SA) packets, acting as an intermediate UPF network element (I-UPF network element) as an uplink classifier (UL-CL) or a branching point UPF network element.

[0122] 4) In addition to the above functions, the UPF network element also has application monitoring, data flow quality of service (QoS) processing, traffic usage reporting, Internet Protocol (IP) management, mobility adaptation, policy control, and charging functions. In addition to network functionality requirements, the UPF network element also considers data security, physical environment requirements, and deployment power consumption indicators.

[0123] The UPF network element is a connection point between the mobile network and the data network, and the important interfaces include N3, N4, N6, N9, N19, etc. The N3 interface is the interface between the next generation radio access network (NG-RAN) and the UPF network element, and uses the GTP-U protocol for tunneling of user data.

[0124] The N4 interface is the interface between the SMF network element and the UPF network element, and the control plane is used to transmit node messages and session messages, using the Packet Forwarding Control Protocol (PFCP) protocol, and the user plane is used to transmit messages that the SMF network element needs to receive or send through the UPF network element, using the GTP-U protocol.

[0125] The N6 interface is the interface between the UPF network element and the external DN, and in specific scenarios (such as enterprise private multi-access edge computing (MEC) access), the N6 interface requires support for dedicated lines or L2 / L3 layer tunnels, and can communicate with the DN network based on IP.

[0126] The N9 interface is the interface between UPF network elements, and in mobile scenarios, an I-UPF network element is inserted between the UE and the PSA UPF network element for traffic forwarding, and the GTP-U protocol is used for transmission of user plane messages between the two UPF network elements.

[0127] The N19 interface is a user plane interface between two PDU Session Anchor (PSA) UPF network elements when using 5G Local Area Network (LAN) services, and directly routes traffic between different PDU sessions without using the N6 interface.

[0128] As can be seen, the protocol stack function of the user plane UPF is fixed (GTP-U), which can only meet the routing and forwarding of UE service or connection data. In the 6G era, with the increase of service types and the generation of new types of data, the current single protocol stack function and its capabilities of the UPF will not be able to meet the on-path processing, routing, forwarding and arbitrary topology transmission of 6G new types of data. The enhancement scheme of the UPF network element after the introduction of new types of data (such as AI data, sensing data, computing data, etc.) in 6G has not been deeply researched.

[0129] Based on the above problems, the present disclosure provides a service processing channel establishment method and device, equipment and storage medium.

[0134] FIG. 2a is an interaction diagram I of a service processing channel establishment method provided by an embodiment of the present disclosure. As shown in FIG. 2a, the service processing channel establishment method includes the following steps:

[0135] S201, the terminal device sends a third request message to the first network element.

[0136] In some embodiments, the terminal device can access a radio access network function network element, and send the third request message to the first network element through the radio access network function network element.

[0137] The third request message is used to request establishment or update of a service processing channel between the terminal device and the UPF network element.

[0138] It should be noted that when the service processing channel has been established between the terminal device and the UPF network element, but the service type or the data type changes, the first request message is used to instruct to update the service processing channel of the terminal device and the UPF network element. When the service processing channel has not been established between the terminal device and the UPF network element, the first request message is used to instruct to establish the service processing channel of the terminal device and the UPF network element.

[0139] In some embodiments, the third request message includes a first parameter, and the first parameter includes at least one of a service type parameter or a data type parameter; wherein the service type parameter is used to indicate the service type, and the data type parameter is used to indicate the data type.

[0140] In some embodiments, the service type includes but is not limited to at least one of a communication service, a sensing service, a computing service or an AI service; and the data type includes but is not limited to at least one of communication data, sensing data, computing data or AI data.

[0141] In some embodiments, the third request message further includes but is not limited to any one of a data amount size or a data delay requirement.

[0142] In some embodiments, the third request message further includes a second parameter, and the second parameter includes at least one of a packet detection rule (PDR), a forwarding action rule (FAR) or a channel identifier.

[0143] In some embodiments, the first network element includes at least one of an SMF network element or a DMF network element.

[0144] In some embodiments, the first network element can be determined according to the service type or the data type corresponding to the first parameter. For example, when the service type is a communication service, or when the data type is communication data, the first network element is an SMF network element, that is, step S201 is to send the third request message to the SMF network element. Or, when the service type is a sensing service, a computing service or an AI service, or the data type is sensing data, computing data or AI data, the first network element is a DMF network element, that is, step S201 is to send the third request message to the DMF network element.

[0145] In some embodiments, when the service type is a communication service, or when the data type is communication data; the terminal device can first send the third request message to the DMF network element, and the DMF network element determines the SMF network element for processing the communication service or the communication data based on the third request message.

[0146] S202, the first network element determines the UPF network element according to the third request message of the terminal device.

[0147] In some embodiments, the first network element, upon receiving the third request message sent by the terminal, selects a UPF network element according to a service type parameter or a data type parameter carried by the third request message.

[0148] In some embodiments, when the first network element is an SMF network element, the SMF network element can select a UPF network element according to DNN, slice, and the like information, wherein the third request message includes network slice identification (Single Network Slice Selection Assistance Information, S-NSSAI) and the like information.

[0149] In some embodiments, when the first network element is a DMF network element, the UPF network element needs to be enhanced, for example, the service interface of the UPF network element is enhanced, or a service interface of a data service is added, so that the DMF network element can communicate with the enhanced UPF network element through the service interface.

[0150] S203. The first network element sends a first request message to the UPF network element.

[0151] The first request message is used to request the UPF network element to enable a first protocol stack corresponding to the third request message, and the first protocol stack is used to establish a service processing channel of the terminal device and the UPF network element.

[0152] In some embodiments, the first request message includes the first parameter described above.

[0153] In some embodiments, the first request message further includes a data processing rule. It should be noted that the content of the data processing rule is not limited in the present disclosure. For example, the data processing rule can include but is not limited to any one or more of fusion, cleaning, and denoising.

[0154] In some embodiments, the first request message further includes a second parameter, and the second parameter includes at least one of a PDR, a FAR, or a channel identifier.

[0155] In some embodiments, the first request message further includes a configuration parameter of the first protocol stack, and the terminal device is configured to configure the first protocol stack based on the configuration parameter.

[0156] In an implementation, if the first network element determines that the UPF network element has configured a corresponding first protocol stack, the first request message includes enabling information, and the enabling information is used to instruct the UPF network element to activate the corresponding first protocol stack.

[0157] In an embodiment, if the first network element determines that the UPF network element has not configured the corresponding first protocol stack, the first request message includes indication information indicating that the UPF network element configures the corresponding first protocol stack.

[0158] In an embodiment, if the first network element does not determine whether the UPF network element has configured the corresponding first protocol stack, the first network element can send the first request message including indication information, and accordingly, when the UPF network element receives the first request message, if the UPF network element determines that the first protocol stack has been configured, the UPF network element directly activates the first protocol stack, and if the UPF network element determines that the first protocol stack has not been configured, the UPF network element configures and activates the first protocol stack.

[0159] S204, the UPF network element enables the first protocol stack corresponding to the first request message based on the first request message.

[0160] The first protocol stack is used to establish a service processing channel.

[0161] In some embodiments, if the first request message carries enabling information, the UPF network element activates the configured first protocol stack corresponding to the first request message based on the first request message.

[0162] In some embodiments, if the first request message carries indication information, the UPF network element configures the first protocol stack corresponding to the first request message based on the first request message and activates the corresponding first protocol stack.

[0163] In some embodiments, when the UPF network element configures the corresponding first protocol stack based on the first request message, the following two cases are included:

[0164] Case 1: The UPF network element configures the corresponding first protocol stack in addition to the second protocol stack and activates the corresponding first protocol stack. The second protocol stack is a protocol stack that the UPF has configured.

[0165] For example, referring to FIG. 2b, FIG. 2b is a schematic diagram of a protocol stack configuration method according to an embodiment of the present disclosure. As shown in FIG. 2b, the UPF network element can add the first protocol stack based on the configured second protocol stack (the second protocol stack in the figure is exemplified by the GTP-U protocol stack).

[0166] It should be understood that the embodiments of the present disclosure are not limited to the type of the newly added first protocol stack. For example, the newly added protocol stack in the figure is exemplified by the "Quick UDP Internet Connections Protocol Stack (QUIC) protocol", the "Segment Routing over IPv6 (SRv6) protocol", the "File Transfer Protocol (FTP) protocol", the "Routing Information Protocol (RIP) protocol", and the "Karaf protocol", and the underlying protocol stack is exemplified by the "Layer 1 Protocol (L1) protocol", the "Layer 2 Protocol (L2) protocol", the IP protocol, and the "User Datagram Protocol (UDP) protocol", but all are not limited thereto.

[0167] The QUIC protocol stack is used to transmit data such as sensing data, intelligent data, and computing data of the terminal device, that is, when the first parameter carried in the third request message is data such as sensing data, AI data, and computing data, or the service type parameter is a service such as a sensing service, an AI service, and a computing service, the first protocol stack can be the QUIC protocol stack.

[0168] When the service data of the terminal device is transmitted, any one of the GTP-U protocol stack or the SRv6 protocol stack can be selected.

[0169] Case 2: The UPF network element configures the protocol header of the first protocol stack in the second protocol stack and activates the corresponding first protocol stack. The second protocol stack is the protocol stack currently configured by the UPF. For example, the GTP-U protocol stack in the second protocol is modified, and the protocol stack is enhanced to support the transmission of multiple data types. It should be understood that in this case, the UPF network element after configuring the first protocol stack is still a single protocol stack.

[0170] For example, referring to FIG. 2c, FIG. 2c is a schematic diagram of a second principle of a protocol stack configuration method according to an embodiment of the present disclosure. As shown in FIG. 2c, for example, the second protocol stack is the GTP-U protocol stack, and on the basis of the GTP-U protocol stack configured by the UPF network element, a new protocol header (the first protocol stack is exemplified by the QUIC protocol) is added, the newly added QUIC protocol carries the GTP-U protocol stack,

[0171] The type of the added protocol stack is not limited in the embodiments of the present disclosure. It should be understood that the added protocol stack is exemplified by QUIC, SRv6, FTP, RIP, and Karaf, and the underlying protocol stack is exemplified by L1, L2, IP, and UDP, but is not limited thereto.

[0172] The QUIC protocol stack is used to transmit data such as sensing data, intelligent data, and computing data of the terminal device, that is, when the first parameter carried in the third request message is data such as sensing data, AI data, and computing data, or the service type parameter is a service such as a sensing service, an AI service, and a computing service, the first protocol stack can be a QUIC protocol stack.

[0173] When the service data of the terminal device is transmitted, at least one of the GTP-U protocol stack or the SRv6 protocol stack can be selected.

[0174] In some embodiments, after enabling the first protocol stack, the UPF network element can further send a first response message to the first network element, where the first response message is used to respond to the first request message, and the first response message is used to indicate that the UPF network element has enabled the first protocol stack.

[0175] Correspondingly, after receiving the first response message, the first network element can further send a second response message to the terminal device, where the second response message is used to respond to the third request message, and the second response message is used to indicate that the UPF network element has established or updated the service processing channel of the terminal device and the UPF network element.

[0176] In the embodiments of the present disclosure, the UPF network element can enable a corresponding protocol stack based on the data type or the service type, and then establish a corresponding service processing channel to process data of each data type or service type through the service processing channel. That is, through the method provided by the embodiments of the present disclosure, the UPF network element can configure multiple sets of protocol stacks, and use different protocol stacks to transmit data of the same data type or different service types.

[0177] Secondly, the UPF network element can design a new protocol stack based on the configured GTP-U protocol stack, so that it can meet the transmission of new data or the processing of new services.

[0178] In addition, by enhancing the UPF network element, for example, by enhancing the service interface of the UPF network element, or by adding a service interface of a data service, the service interface of the UPF data service can be increased, so that the DMF network element can communicate with the enhanced UPF network element through the service interface.

[0179] Through the method provided by the embodiments of the present disclosure, the following beneficial effects can be achieved:

[0180] 1. Protocol stack capability enhancement, from a single protocol stack to multiple protocol stacks, different protocol stacks can meet the same type of data transmission or different types of data transmission.

[0181] 2. Service capability enhancement of UPF network element, increase the service interface between DMF, make DMF call the service interface between UPF and directly interact with it, and then complete the establishment of data channel.

[0182] 3. Enhancement of data sensing and processing capability of UPF network element, which can sense the type of data and its processing capability for data, such as data aggregation, deduplication, denoising, etc.

[0183] 4. Further enhancement of UPF shunting capability, that is, to identify the type of data and shunt different types of data to different destinations.
