Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to communication methods and devices. Background Art

[0002] The sixth generation (6G) network needs to support the scheduling of artificial intelligence (AI) resources and the processing of large amounts of data to reduce the computing power and energy consumption of terminal devices to meet the requirements of lighter, more immersive and smarter terminal devices. As a result, the 6G network architecture will change from "connection-centric" to "task-centric". Among them, the traditional "connection-centric" network architecture aims to provide the connection channels required for data communication between terminal devices and terminal devices, and between terminal devices and application servers, as well as the corresponding life cycle management mechanism and communication service quality (QoS), while the "task-centric" network architecture requires not only the network to provide connection services, but also the network to coordinate and allocate the computing power, connection, algorithm and data resources of network nodes to jointly achieve a specific goal. However, how to enable network element nodes (such as access network devices) within the network to provide data or computing services to terminal devices has become an urgent problem to be solved.

In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each piece of information agreed in advance (for example, stipulated by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each piece of information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0125] In addition, the specific indication method may also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can refer to the relevant descriptions in the existing implementation methods, which will not be repeated herein. As can be seen from the above, for example, when it is necessary to indicate multiple information of the same type, different indication methods may be used for different information. In the specific implementation process, the desired indication method can be selected according to specific needs. The embodiment of the present application does not limit the selected indication method. In this way, the indication method involved in the embodiment of the present application should be understood to cover various methods that can enable the party to be indicated to obtain the information to be indicated.

[0126] The information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. Among them, the sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting device by sending configuration information to the receiving device. Among them, the configuration information can include, for example, but not limited to, one or a combination of at least two of radio resource control (RRC) signaling, medium access control (MAC) layer signaling and physical layer signaling. Among them, MAC layer signaling, for example, includes MAC-control element (CE); physical (PHY) layer signaling, for example, includes downlink control information (DCI).

[0127] Second, in the embodiments of the present application, the first, second and various digital numbers are only used for the convenience of description and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different indication information. For another example, the first network area and the second network area are only used to distinguish different areas, and their order is not limited. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0128] Third, in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that under certain objective circumstances, the device (such as a terminal device or a network device) will make corresponding processing. It does not limit the time, nor does it require the device (such as a terminal device or a network device) to have a judgment action when implementing it, nor does it mean that there are other limitations.

[0129] Fourth, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way for easy understanding.

[0130] Fifth, in the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of multiple items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0131] Introduction to communication systems and applicable network elements, as well as related terminology.

[0132] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as wireless fidelity (Wi-Fi) systems, vehicle to everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Vehicles communication systems, world-wide interoperability for microwave access (WiMAX) communication systems, fourth-generation (4G) mobile communication systems, such as long-term evolution (LTE) systems, world-wide interoperability for microwave access (WiMAX) communication systems, fifth-generation (5G) mobile communication systems, such as new radio (NR) systems, and future communication systems, such as 6G mobile communication systems.

[0133] As many industries such as healthcare, factories, ports, coal mines, government and enterprises accelerate their digital transformation, computing and communications are becoming the core basic capabilities that enable the digital transformation of industries. Therefore, operators have proposed the concept of computing power network and organized standardization discussions in 3GPP. The meaning of computing power network is to perceive ubiquitous computing and services through the network, dispatch computing tasks to appropriate computing nodes for processing, improve the utilization efficiency of network resources and computing resources, and provide users with low-latency and highly reliable business services to ensure user experience.

[0134] In view of 6G network and future business needs, such as the low latency requirements of immersive services such as extended reality (XR) and holographic, and the real-time processing requirements of massive data for intelligent services such as robots, intelligent bodies and AI generated content (AIGC) large models, the IMT-2030 (6G) Promotion Group believes that 6G services will be immersive and intelligent. 6G networks need to support the scheduling of AI resources and the processing of very large amounts of data to reduce the computing power and energy consumption of terminal devices to meet the requirements of lighter, more immersive and smarter terminal devices. Therefore, it is proposed that Figure 1 The X as a service (XaaS) architecture shown in the figure, under which communication equipment has capability exposure, collaborative control, orchestration management and security functions, so that the 6G network architecture will change from "connection-centric" to "task-centric".

[0135] The traditional "connection-centric" network architecture aims to provide the connection channels required for data communication between terminal devices and terminal devices, and between terminal devices and application servers, as well as the corresponding lifecycle management mechanism (e.g., creation, modification, deletion, anchor migration, etc. of end-to-end communication tunnels) and communication QoS guarantee. For example, the connection establishment method of the 5G network, namely the protocol data unit (PDU) session establishment process, is to provide a transmission channel for data transmission between the terminal device and the application server (application server) located in the data network (DN), including the establishment of the data radio bearer (DRB) between the terminal device and the radio access network (RAN) and the NG interface user plane channel (NG-U Tunnel) between the RAN and the user plane function (UPF) of the core network, and provide corresponding QoS guarantee.

[0136] The "task-centric" network architecture requires not only the network to provide connection services, but also to coordinate and allocate the computing power, connections, algorithms, and data resources of network nodes to jointly achieve a specific goal. The 6G network provides computing services by introducing computing power, storage resources, and a mechanism for the coordination of computing power, algorithms, and data among multiple nodes.

[0137] like Figure 2 As shown, a computing network architecture that can be used to schedule computing tasks is shown. It uses the connection capabilities of wireless networks and the computing power that is widely available in the network to provide high-performance computing power, low-latency transmission, and intelligent business assurance services for a variety of computing services. Figure 2 In the architecture shown, the computing management function (CMF) is deployed on the RAN side to perform computing power awareness, computing service awareness, network status awareness, and computing task scheduling. CMF can schedule services initiated by network elements, external networks, or third-party applications to computing nodes such as terminal devices, mobile edge computing (MEC) platforms, cloud servers, and RAN devices for execution.

[0138] However, the current 5G network provides a transmission channel for data transmission between terminal devices and application servers located in the DN by establishing PDU sessions, and the QoS of the session is also for the services provided by the application server, which is not suitable for network element nodes inside the network to provide data or computing services to terminal devices. Therefore, how to enable network element nodes inside the network (such as access network devices) to provide data or computing services to terminal devices has become an urgent problem to be solved.

[0139] To this end, an embodiment of the present application provides a communication method that can enable access network equipment and / or user-plane network elements to provide data or computing services to terminal devices.

[0140] For example, Figure 3 The following is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Figure 3 As shown, the communication system includes: terminal equipment, access network equipment, user plane network elements and session management network elements, and each of them can communicate with each other.

[0141] 1. Terminal equipment

[0142] The terminal device may be one or more, such as a first terminal device, a second terminal device, a third terminal device, etc. The terminal device may be a terminal device with a transceiver function, or may be a chip or a chip system provided in the terminal device. The terminal device may also be referred to as user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device.

[0143] The embodiments of the present application do not limit the device form of the terminal. The device for realizing the function of the terminal device can be a terminal device; it can also be a device that can support the terminal device to realize the function, such as a chip system. The device can be installed in the terminal device or used in combination with the terminal device. In the embodiments of the present application, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0144] 2. Access network equipment

[0145] In the embodiment of the present application, the access network device can provide services locally for the terminal device. The service can also be called a local service, a local computing service, a local data service, etc., such as an AI reasoning service, an AI training service, an AI service or a data service, such as a perception data service or a positioning data service.

[0146] In the embodiment of the present application, local service may refer to a service provided locally to a terminal device by a network internal node (such as an access network device or a user plane network element) as a service provider, that is, the starting point for providing the service is a network internal node, such as a service provided by an application (APP) deployed therein. In other words, for a service provided by network node 1 to a terminal device via network node 2, the service is a local service provided by network node 1, and is not a local service provided by network node 2.

[0147] The access network device may be multiple, such as a first access network device, a second access network device, a third access network device, etc. The access network device may also be referred to as an access network node, a RAN node, a RAN entity or an access node, etc., located on the network side of the above-mentioned communication system, to help the terminal device achieve wireless access, and a device with a wireless transceiver function or a chip or chip system that can be set in the device. The access network device includes but is not limited to: a base station, an evolved base station (evolved NodeB, eNodeB), an access point (access point, AP), a transmission reception point (transmission reception point, TRP or transmission point, TP), a next generation base station (next generation NodeB, gNB), a next generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system, etc. The access network device may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, an open radio access network (open radio access network, ORAN) or a wireless controller in a centralized radio access network (centralized radio access network, CRAN) scenario. The access network device may also be one or a group of antenna panels (including multiple antenna panels) of a base station in 5G, or it may also be a network node constituting a gNB, TRP or TP or a transmission measurement function (TMF), such as a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), a road side unit (RSU) with a base station function. Optionally, the access network device may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in V2X technology may be an RSU. All or part of the functions of the network device in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, a logical module or software that can implement all or part of the functions of the access network device.

[0148] Among them, CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH). It can be understood that the access network device can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, CU can be divided into a network device in the access network RAN, and CU can also be divided into a network device in the CN, which is not limited here.

[0149] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0150] In the embodiments of the present application, the form of the access network device is not limited. The device for realizing the function of the access network device may be the access network device; or it may be a device capable of supporting the access network device to realize the function, such as a chip system. The device may be installed in the access network device or used in conjunction with the access network device.

[0151] 3. User plane network element

[0152] In the embodiment of the present application, the user plane network element can also locally provide services for the terminal device, for packet routing and forwarding, and QoS processing of user plane data. The user plane network element can perform user data packet forwarding according to the routing rules of the session management network element, such as sending uplink data to the data network or other user plane network elements, and forwarding downlink data to other user plane network elements or access network devices. The user plane network element can be a UPF in 5G communication.

[0153] 4. Session Management Element

[0154] The session management network element is used to implement session management of terminal devices, which can trigger the user plane device to provide local computing services to the terminal device to establish a data channel, and allocate resources and release resources for the session of the terminal device. Among them, the resources include resource preset parameters QoS, session path, forwarding rules, etc. The session management network element can be a session management function (SMF) network element in the 5G system.

[0155] The communication system provided in the embodiment of the present application may introduce a computing management function entity to implement some or all operations related to the computing management function. The computing management function entity may also be referred to as a computing management function, a computing management function network element, a computing management function node, a computing management function device, a computing management function module, a computing management function model, or a computing management function unit, etc. As described above, the computing management function entity may be a network element built into the communication system. For example, the computing management function entity may be a computing management function module built into: a terminal device, an access network device, a core network network element, a cloud server, or an operation, administration and maintenance (OAM) (which may be referred to as a network management) to implement functions related to the computing management function. The OAM may be a network management as a core network network element and / or as a network management as an access network device. Alternatively, the computing management function entity may also be a network element independently set up in the communication system. Optionally, the terminal device or the chip built into the terminal device may also include a computing management function entity to implement functions related to the computing management function. Optionally, the computing management function may be referred to as CMF, or other names, which are not limited in this application. The computing management functional entity has one or more of the following functions: computing power awareness, computing business awareness, network status awareness or computing task scheduling, which can realize the orchestration and management of computing power resources.

[0156] It should be understood that Figure 3 The communication system shown may also include other core network elements, other terminal devices or other access network devices, such as access and mobility management elements, data management elements, policy control elements, etc., without limitation. Among them, the access and mobility management element may be an access and mobility management function (AMF) in a 5G system, the data management element may be a unified data management (UDM) in a 5G system, and the policy control element may be a policy control function (PCF) in a 5G system.

[0157] In addition, the embodiment of the present application also provides a protocol stack architecture suitable for completing computing services between a terminal device and an access network device. In the embodiment of the present application, the computing service process mainly involves the following two types of information or signaling or messages:

[0158] (1) Control: information on computing resource perception, management, computing task request, scheduling, and allocation;

[0159] (2) Data type: information on data types such as computing task data (such as rendering data), algorithms or models (such as AI models), etc.

[0160] like Figure 4 As shown, terminal devices and access network devices are deployed with APP to provide computing services. For computing services, two types of protocol stack architectures are mainly provided. One type is a shared control plane protocol stack architecture, such as Figure 4 The architectures shown in (a) and (b) are that both control information and data information are transmitted using the control plane protocol stack, and the other is a user plane-control plane separated protocol stack architecture, that is, data information is transmitted through the user plane protocol stack, and control information is transmitted through the control plane protocol stack.

[0161] For the first type of protocol stack architecture, based on the CMF deployment method, there are Figure 4 The two architectures shown in (a) and (b) are as follows. Figure 4 As shown in (a), CMF is independently deployed on the terminal device and the access network device. It can be understood that the terminal device and the access network device include a CMF module, and the control plane protocol stack of the terminal device and the access network device. The computing resource control (CRC) layer is introduced on the basis of the existing control plane protocol stack architecture. For the sending end, the control information related to CMF and the data information provided by the APP can be sent after being encapsulated and processed by the CRC layer, RRC layer, layer (layer, L) 2, and L1 in sequence; for the receiving end, the received data is decapsulated and processed by the L1, L2, RRC layer, and CRC layer in sequence to obtain the CMF-related control information and the data provided by the APP. Among them, the data provided by the APP can be carried in the information element (IE) of the container type contained in the CRC message and sent.

[0162] like Figure 4 As shown in (b), CMF is embedded in the RRC layer, and the RRC layer is enhanced to generate CMF-related control information. A new IE can be introduced into the RRC message to carry CMF-related control information and data provided by the APP.

[0163] Based on the above Figure 4 The shared control plane protocol stack architecture shown in (a) and (b) can realize the mapping of CMF-related control information and data provided by APP to specific signaling radio bearers (SRBs), as well as addressing the App of the access network device and the App of the terminal device through the control plane protocol message of the access network device, that is, discovering the App. This control plane transmission method can reuse the same mechanism as the current RAN AI (RAN AI refers to the use of AI to optimize the RAN's own communication services, such as cell switching, cell traffic prediction, user mobility prediction, etc., which can be regarded as RAN local APP) transmission, and use control plane signaling to transmit APP data and control signaling.

[0164] The mapping of CMF-related control information and data provided by the APP to specific SRBs can adopt the following rules:

[0165] (1) All CMF-related control information, such as computing task requests, scheduling, computing resource perception and management, is carried out through the common SRB.

[0166] (2) Use specific SRBs (such as SRB 1 to N) to carry messages of APP data with different QoS requirements, such as input and output data of computing (sub)tasks, algorithm and model data related to the App program, calculation result return data, etc.

[0167] The above-mentioned public SRB and specific SRB may reuse existing SRB resources, or define new computing radio bearers (CRBs) based on existing DRB and SRB resources, and there is no limitation on this.

[0168] For the second type of protocol stack architecture, similar to the first type of architecture, there are deployment methods based on CMF such as Figure 4 The two architectures shown in (c) and (d) are as follows. Figure 4 As shown in (c), CMF is independently deployed on terminal devices and access network devices, or CMF is independently deployed on terminal devices and access network devices as a sinking core network function. The CRC layer is introduced on the basis of the existing control plane protocol stack architecture to carry CMF-related control information. The data provided by the APP is transmitted through the existing user plane protocol stack.

[0169] like Figure 4 As shown in (d), CMF is embedded in the RRC layer to enhance the RRC layer. The RRC message carries CMF-related control information, and the data provided by the APP is transmitted through the existing user plane protocol stack.

[0170] Based on the above Figure 4 In the protocol stack architecture with user plane-control plane separation shown in (c) and (d), the data provided by the APP is transmitted through the existing user plane protocol stack, and the control information related to the CMF is transmitted through the control plane protocol stack. Under this architecture, the access network equipment locally deploys core network functions such as local UPF (local UPF), and the transmission of computing service data passes through the Local UPF. The existing 5G NR protocol process can be reused, and corresponding session management and other processes are introduced for computing services. The mapping of the data provided by the APP to the DRB can refer to the existing implementation method, and the mapping of the control information related to the CMF to the SRB can refer to the mapping rules of the above-mentioned type of protocol stack architecture.

[0171] Figure 4 In the illustrated protocol layer architecture, the protocol layers specifically involved in L1 and L2 are not drawn. It should be understood that, from bottom to top, the protocol layers included in L1 are the PHY layer, the protocol layers included in L2 are the MAC layer, the RLC layer and the PDCP layer, and the RRC layer belongs to L3. In addition, the newly added CRC layer can be divided into L3 or higher layers, which is not limited.

[0172] It should be noted that Figure 4 The protocol layer architecture shown is that the CRC layer is deployed above the RRC layer, and it can also be deployed below the RRC layer, without limitation. CRC as a computing resource control entity can be deployed as a protocol layer or as a functional module, without limitation.

[0173] For the above communication system, exemplarily, Figure 5 A schematic diagram of the structure of an access network device based on a CU-DU separation architecture provided in an embodiment of the present application. Figure 5 As shown, by dividing the protocol stack, the access network device includes CU-CP, CU-UP and DU, and the CU-CP and DU can communicate through interface 1, and the CU-UP and DU can communicate through interface 2. Optionally, the access network device may be a gNB, in which case interface 1 may be an F1-C interface, and interface 2 may be an F1-U interface.

[0174] Among them, CU-CP includes the RRC layer and the packet data convergence protocol (PDCP) layer, CU-UP includes the service data adaptation protocol (SDAP) layer and the PDCP layer, and DU includes the radio link control (RLC) layer, the MAC layer and the PHY layer. It can be seen that both CU-CP and CU-UP include the PDCP layer, the RRC layer is located above the PDCP layer in CU-CP, and the RRC message is encapsulated into a PDCP data packet data unit (PDU) after being processed by the PDCP layer. The PDCP data PDU can be sent by CU-CP and CU-UP respectively.

[0175] In such Figure 4 In the protocol stack architecture of the access network device shown in (a) or (c), a CRC layer is added. When CU-DU division is performed, the CRC layer can be located in the CU.

[0176] The PDCP control PDU is generated by the PDCP layer and is used to transmit robust header compression (ROHC) context information, etc., and is usually sent by the PDCP layer of the CU-UP.

[0177] In an embodiment of the present application, the computing management function may be integrated into the CU or DU, or may be integrated into a CU-CP or CU-UP further separated from the CU.

[0178] In the scenario of access network equipment based on CU-DU separation architecture, in one possible implementation method, the generation of control information such as indication information, configuration information, scheduling information, and data processing involved in the embodiments of the present application can be performed by the CU, and a CMF can be deployed on the CU. During uplink transmission, after the DU receives the indication information and / or data from the terminal device, the CU needs to send it to the DU for processing; during downlink transmission, the CU sends the generated control information or data to the DU, and then the DU sends it to the terminal device. At this time, the control information / data can be carried in the DCI or MAC CE for transmission.

[0179] In one possible implementation, the generation of control information such as indication information, configuration information, scheduling information, and data processing involved in the embodiments of the present application can be performed by the DU, and a CMF can be deployed on the DU. After determining the control information or data, the DU can submit the control information or data to the CU, and the CU carries the control information or data in an RRC message or PDCPcontrol PDU and sends it to the terminal device.

[0180] Another example, Figure 6 The present invention provides a schematic diagram of the structure of an access network device based on the O-RAN architecture. Figure 6 As shown, the access network device includes an intelligent controller (RAN intelligent controller, RIC), for example, the RIC can be an AI module for implementing AI-related functions. The RIC can include a near real-time RIC (near real-time RIC, NRT-RIC) and a non-real-time RIC (non-real-time RIC, Non-RT RIC).

[0181] NRT-RIC is used for model training and reasoning. For example, it is used to train an AI model and use the AI ​​model for reasoning. NRT-RIC can obtain information on the network side and / or the terminal device side from access network equipment (such as CU, CU-CP, CU-UP, DU and / or RU) and / or terminal equipment. This information can be used as training data or reasoning data. Optionally, NRT-RIC can submit the reasoning results to the access network equipment and / or terminal equipment. Optionally, the reasoning results can be exchanged between the CU and DU, and / or between the DU and RU. For example, NRT-RIC submits the reasoning results to the DU, and the DU sends it to the RU.

[0182] Non-RT RIC is used for model training and reasoning. For example, it is used to train an AI model and use the AI ​​model for reasoning. Non-RT RIC can obtain information on the network side and / or the terminal device side from access network equipment (such as CU, CU-CP, CU-UP, DU and / or RU) and / or terminal equipment. The information can be used as training data or reasoning data, and the reasoning result can be submitted to the access network equipment and / or terminal equipment. Optionally, the reasoning results can be exchanged between the CU and the DU, and / or between the DU and the RU. For example, the Non-RT RIC submits the reasoning result to the DU, and the DU sends it to the RU.

[0183] NRT-RIC and Non-RT RIC can also be set up as a network element separately. Optionally, NRT-RIC and Non-RT RIC can also be part of other devices. For example, NRT-RIC is set up in the access network device (for example, in the CU or DU), while Non-RT RIC is set up in the OAM, the cloud server, the core network element, or other network devices.

[0184] like Figure 6 As shown in (a), the access network device includes NRT-RIC, CU and DU. NRT-RIC integrates a computing management functional entity and runs a third-party application. NRT-RIC communicates with DU through interface 3, NRT-RIC communicates with CU through interface 4, and CU and DU communicate through interface 5. Optionally, the access network device may be a gNB, interface 3 and interface 4 may be E2 interfaces, and interface 5 may be an F1 interface.

[0185] Under this architecture, the generation of control information such as indication information, configuration information, scheduling information, and data processing involved in the embodiments of the present application are performed by NRT-RIC. During downlink transmission, NRT-RIC can send control information or data to DU through interface 2, and then DU sends it to the terminal device. At this time, the control information or data can be carried in DCI or MAC CE for transmission. Alternatively, NRT-RIC can send control information or data to CU through interface 4, and then CU sends it to DU through interface 5, and then DU sends it to the terminal device. At this time, the control information or data can be carried in RRC message or PDCPcontrol PDU for transmission. Similarly, during uplink transmission, after DU receives indication information or data from the terminal device, it can be sent to NRT-RIC through CU or directly to NRT-RIC.

[0186] Another example Figure 6 As shown in (b), the access network device includes a computing management function entity (which may also be referred to as a computing management function module), a CU and a DU. The computing management function entity integrates NRT-RIC and runs a third-party application. The computing management function entity communicates with the DU through interface 6, the computing management function entity communicates with the CU through interface 7, and the CU and the DU communicate through interface 8. Optionally, the access network device may be a gNB, interface 6 and interface 7 may be E2 interfaces, and interface 8 may be an F1 interface.

[0187] Under this architecture, the generation of control information such as indication information, configuration information, scheduling information, and data processing involved in the embodiments of the present application are performed by the computing management function. During downlink transmission, the computing management function can send the control information or data to the DU through interface 2, and then the DU sends it to the terminal device. At this time, the control information or data can be carried in the DCI or MAC CE for transmission. Alternatively, the computing management function can send the control information or data to the CU through interface 4, and then the CU sends it to the DU through interface 5, and then the DU sends it to the terminal device. At this time, the control information or data can be carried in the RRC message or PDCP control PDU for transmission. Similarly, during uplink transmission, after the DU receives the indication information or data from the terminal device, it can be sent to the computing management function through the CU or directly to the computing management function.

[0188] A possible implementation is Figure 6 The NRT-RIC can also be replaced by non-NRT RIC. The non-NRT RIC can integrate computing management functional entities and third-party applications, or the computing management functional entity can integrate non-NRTRIC functions and third-party applications. There is no limitation on this.

[0189] The embodiments of the present application combine local service provision with the existing O-RAN architecture, with minimal changes to the architecture and interfaces of O-RAN. In addition, third-party applications run in an open RIC module, which does not cause security concerns and facilitates local service provision by access network devices.

[0190] It should be understood that the names of nodes, modules, devices or network elements in different scenarios, architectures or systems, as well as the names of communication interfaces between nodes, modules, devices or network elements are given by way of example in the embodiments of the present application, and the possibility of name changes in future communication systems, scenarios or architectures is not excluded.

[0191] The following will be combined Figure 7-10 The communication method provided in the embodiment of the present application is specifically described. The communication method can be applied to Figure 3The communication between the terminal device, access network device, user plane device and session management network element shown. Among them, the subject that executes the session management network element action in the method can also be a device / module in the session management network element, such as a chip, processor, processing unit, etc. in the session management network element, and the embodiment of the present application does not make specific limitations on this. The subject that executes the access network device action in the method can also be a device / module in the access network device, such as a chip, processor, processing unit, etc. in the access network device, and the embodiment of the present application does not make specific limitations on this. The subject that executes the user plane network element action in the method can also be a device / module in the user plane network element, such as a chip, processor, processing unit, etc. in the user plane network element, and the embodiment of the present application does not make specific limitations on this. The subject that executes the terminal device action in the method can also be a device / module in the terminal device, such as a chip, processor, processing unit, etc. in the terminal device, and the embodiment of the present application does not make specific limitations on this.

[0192] For example, Figure 7 A flow chart of a communication method provided in an embodiment of the present application. Figure 7 As shown, the communication method includes the following steps:

[0193] S701. The session management network element obtains first indication information.

[0194] Among them, the first indication information is used to indicate the service provided by the access network device and / or the user plane network element to the terminal device, and the first indication information may include information such as the provider of the service, the type of service (type) or the identity (ID) of the service. Among them, the session management network element may be the SMF in the 5G system, the access network device may be the gNB in ​​the 5G system, and the user plane network element may be the UPF in the 5G system. In the embodiment of the present application, the service provided by the access network device and / or the user plane network element to the terminal device may also be referred to as a local service, that is, the provider or source of the service is the access network device and / or the user plane network element, and the access network device and / or the user plane network element may also be referred to as the user plane device of the terminal device.

[0195] It should be understood that the access network equipment can provide services to the terminal equipment independently, the user plane network element can also provide services to the terminal equipment independently, and the access network equipment and the user plane network element can provide services to the terminal equipment at the same time. The services provided can be the same or different, and there is no limitation on this.

[0196] The services in the embodiments of the present application may include two major types. One type is computing services, which may include: the access network device and / or the user-side network element performs the computing task requested by the terminal device, and sends the result of the computing task to the terminal device, where the computing task may be such as AI reasoning tasks, AI training tasks, AR rendering tasks, etc.; the other type is data services, which may include: the access network device and / or the user-side network element obtains the data or AI model requested by the terminal device, and sends the data or AI model to the terminal device, where the data may be such as perception data, positioning data, measurement data, etc. It should be understood that in addition to the above two types of services, the embodiments of the present application may also include other types of services, which are not limited to this.

[0197] In a possible design scheme, the terminal device sends a first indication message to the session management network element. Accordingly, the session management network element receives the first indication message from the terminal device. Under this design scheme, in a possible implementation, the terminal device sends a session establishment request message to the session management network element. Accordingly, the session management network element receives a session establishment request message from the terminal device. Among them, the session establishment request message carries the first indication information. The session establishment request message includes the first indication information. The session establishment request message is used by the terminal device to request to establish a session for the service. That is, the terminal device can request the access network device and / or the user plane network element to provide a service through the session establishment request message.

[0198] At this time, the first indication information can be implicitly represented by a special assignment or a combination of multiple assignments of any one of the information elements such as the PDU session identifier (PDU Session ID), the terminal device identifier (UE ID), the internet protocol (IP) or MAC address (UE IP / MAC address) of the terminal device, the data network name (DNN) (UE Requested DNN) identifier requested by the terminal device, the single network slice selection assistance information (S-NSSAI) identifier and the request type (Request Type) in the session establishment request message. For example, a new value is set for the S-NSSAI identifier, the UE Requested DNN identifier, the PDU Session ID, or the Request type to indicate the service provided by the access network device and / or the user plane network element to the terminal device. For another example, a new service type field, such as a "local PDU session" or "computing PDU session" field, can be added to the reserved field (Reserve Field) of the Request Type to indicate the service provided by the access network device and / or the user plane network element to the terminal device. For example, a new value is set for the Requested PDU Session Type carried in the N1 SMcontainer in the session establishment request message, or a new field is added to indicate the services provided by the access network device and / or the user plane network element to the terminal device.

[0199] It should be understood that the first indication information or session establishment request message can be sent by the terminal device to the session management network element through the access network device, the mobile and access management network element. Among them, the mobile and access management network element can be the AMF in the 5G system. In addition, the terminal device can also carry the first indication information in other defined or newly defined messages, such as computing service request messages or data service request messages, etc., without limitation.

[0200] In another possible design, the operation management network element sends the first indication information to the session management network element. Correspondingly, the session management network element receives the first indication information from the operation management network element. The operation management network element may be an OAM in a 5G system, as an execution of a network management trigger service.

[0201] S702. The session management network element obtains QoS information corresponding to the service according to the first indication information.

[0202] In an embodiment of the present application, after receiving the first indication information, the session management network element may negotiate with the data management network element to obtain the user contract session information, and initiate a request to the policy control network element to obtain the session policy information of the terminal device, so as to obtain the session policy information of the terminal device, and the session policy information includes QoS information corresponding to the service. Among them, the data management network element may be the UDM in the 5G system, and the policy control network element may be the PCF in the 5G system. The QoS information corresponding to the service may include computing power requirement information for executing the service and / or data transmission requirement information for executing the service. The QoS information may be QoS for a service, or may refer to QoS for a class of services, without limitation.

[0203] Among them, the computing power requirement information for executing the service (also referred to as computing power QoS information) may include at least one of the following: the type of computing task, input data rate, output data rate, computing delay requirement, computing load requirement, computing accuracy requirement, or computing energy consumption requirement, etc.

[0204] The type of computing task may refer to the computing power type of the physical hardware required to execute the computing task corresponding to the service, such as a central processing unit (CPU), a graphics processing unit (GPU), a neural network processing unit (NPU), or a tensor processing unit (TPU); or, the type of computing task may refer to the business type corresponding to the computing task, such as image / video recognition, compression, graphics rendering, AI training, AI reasoning, perception processing, high-performance computing, or big data offline analysis.

[0205] The input / output data rate requirement (or demand) may indicate (or reflect, or represent) the input / output data volume requirement to characterize the communication QoS requirement of the computing task. The computing task requirement includes the communication QoS requirement of the computing task, and the communication QoS requirement of the computing task may also include the communication QoS parameters defined by 5G NR, such as uplink / downlink packet delay budget (packet delay budget uplink / downlink, UL / DL PDB), guaranteed bit rate (guarantee bitrate, GBR), maximum data burst volume (maximum data burst volume, MDBV) and other 5G QoS parameters, which may be represented by a 5G QoS identifier (5G QoS identifier, 5QI).

[0206] The computing load requirement may indicate (or reflect, or indicate) the requirement for computing power to perform computing tasks, and may be expressed as the requirement for the computing power of the processor. The computing power of the processor may include the number of operations (operations per second, OPS) that the processor can perform per second (s) or the number of floating-point operations (floating-point operations per second, FLOPS), the model of the processor, the memory capacity, the I / O speed, or the main frequency, etc. For example, the computing load requirement includes how many hertz (Hz) or gigahertz (GHz) the main frequency needs to reach, how many gigabits per second (Gbits / s) the number of read / write operations per second (IOPS) needs to reach, and how many bytes of memory capacity are required, etc.

[0207] The requirement for computing latency may indicate (or reflect, or represent) the time requirement for completing a computing task, such as how long it takes to complete the computing task.

[0208] The demand for computing energy consumption may also indicate (or reflect, or represent) computing power consumption demand, which may refer to the demand for power or energy consumed by a device that performs a computing task. For example, the computing task may be performed by a terminal device, and the demand for computing power consumption may include the computing power consumption requirement for the terminal device. The computing power consumption requirement for the terminal device may be the requirement for the average computing power consumption of the terminal device to perform tasks over a period of time, and the duration for calculating the average computing power consumption may be predefined or preconfigured. Alternatively, the computing power consumption requirement may also be the requirement for the computing power consumption of the terminal device after completing a processing or in a short period of time (such as processing a video frame or a task). Among them, the computing power consumption may also be converted into a corresponding computing energy consumption indicator, and the unit may be a convertible unit such as watts or joules.

[0209] The computational accuracy requirement can indicate (or reflect, or express) the error requirement between the computational result and the actual result, such as the error not exceeding 5%. Alternatively, the computational accuracy requirement can also refer to the accuracy requirement of the inference / training result obtained by inference or training using the AI ​​model / algorithm.

[0210] The data transmission requirement information for executing the service (also referred to as data transmission QoS information) may include at least one of the following: data transmission delay requirement, data transmission reliability requirement, or priority information, etc. Among them, the data transmission delay requirement may refer to the delay requirement required for the access network device and the terminal device to complete the data transmission related to the service, or it may be the delay requirement required for the terminal device to receive data related to the service provided by the access network device and / or the user plane network element. The data transmission reliability requirement may refer to the reliability requirement for data related to the transmission service, for example, the requirements for the bit error rate, jitter, packet loss rate, etc. of the transmission. The priority information is used to indicate the execution priority of the service, and when there are multiple services, it is used for the access network device and / or the user plane network element to determine the order in which multiple services are executed.

[0211] In a possible design scheme, the session management network element may also issue a configuration that satisfies the QoS requirements contained in the QoS information to the access network device and / or the user plane network element based on the QoS information. It should be understood that in the embodiment of the present application, when the user plane network element provides a service for the terminal device, the QoS information corresponding to the service includes the QoS information between the access network device and the terminal device and the QoS information between the access network device and the user plane network element, and the QoS information between the user plane network element and the access network device, and may also include configuration information related to NG-tunnel such as routing priority and congestion avoidance.

[0212] Therefore, after the session management network element obtains the QoS information corresponding to the service, it sends the QoS information corresponding to the service to the service provider, that is, the access network device and / or the user plane network element, so that the access network device and / or the user plane network element establishes service-related data channels according to the QoS information corresponding to the service.

[0213] In a possible scenario, only the access network device provides services for the terminal device. In this case, the method provided in the embodiment of the present application further includes the following S703a:

[0214] S703a: The session management network element sends QoS information corresponding to the service to the access network device. Correspondingly, the access network device receives the QoS information corresponding to the service from the session management network element.

[0215] In this scenario, the session management network element may carry the QoS information corresponding to the service in the session resource establishment request and send it to the access network device.

[0216] In another possible scenario, only the user plane network element provides services for the terminal device. In this case, the method provided in the embodiment of the present application further includes the following S703b:

[0217] S703b: The session management network element sends the QoS information corresponding to the service to the user plane network element. Correspondingly, the user plane network element receives the QoS information corresponding to the service from the session management network element.

[0218] In this scenario, the session management network element may carry the QoS information corresponding to the service in the tunnel establishment request and send it to the user plane network element. In this scenario, since the data related to the service provided by the user plane network element needs to be forwarded by the access network device to the terminal device, the session management network element may also send the QoS information corresponding to the service to the access network device, or only send the QoS information used between the access network device and the terminal device, or the user plane network element may send the corresponding QoS information to the access network device, and there is no limitation on this.

[0219] In another possible scenario, the access network device and the user plane network element provide services to the terminal device at the same time. In this case, the method provided in the embodiment of the present application also includes the above-mentioned S703a and S703b.

[0220] In this scenario, the services provided by the access network device and the services provided by the user plane network element can be the same or different. That is, the session management network element will obtain the QoS information corresponding to the services provided by the access network device and the QoS information corresponding to the services provided by the user plane network element, and send them to the access network device and the user plane network element respectively.

[0221] S704: The access network device sends the first configuration to the terminal device. Correspondingly, the terminal device receives the first configuration from the access network device.

[0222] Among them, the first configuration is used to configure the terminal device to establish a first wireless bearer for service between the terminal device and the access network device. The first wireless bearer for service may include a wireless bearer for services provided by user-plane network elements and / or a wireless bearer for services provided by the access network device.

[0223] In a scenario where only the access network device provides services to the terminal device, such as S703a above, the first wireless bearer is used to transmit data related to the service provided by the access network device. In one possible implementation, after receiving the QoS information, the access network device can perceive the local computing power status based on the computing management function, and determine whether the local computing power status meets the computing power QoS requirements in the QoS information. If the computing power QoS requirements are met, it is determined that the requested service can be executed, and the relevant configuration of the first wireless bearer used to carry the service-related data is determined according to the data transmission requirements in the QoS information, that is, the first configuration, such as completing the mapping between the data transmission QoS requirements and the resource configuration of the wireless bearer, and different wireless bearers are used to transmit data with different data transmission QoS requirements. Among them, the access network device locally configures the mapping relationship between the data transmission QoS requirement information and the wireless bearer configuration parameters.

[0224] In another possible implementation, after receiving the QoS information, the access network device can perceive the local computing power state based on the computing management function, and determine whether the local computing power state meets the computing power QoS requirements in the QoS information. If the computing power QoS requirements are met, it is determined that the requested service can be executed, and further determines the relevant configuration of the first wireless bearer used to carry service-related data based on the computing power QoS requirements, that is, the first configuration, such as completing the mapping between the computing power QoS requirements and the wireless bearer configuration, and different wireless bearers are used to transmit data with different computing power QoS requirements. Among them, the access network device locally configures the mapping relationship between the computing power QoS requirement information and the wireless bearer configuration parameters, for example, the mapping relationship between the computing delay, computing load or computing accuracy and the wireless bearer configuration parameters.

[0225] In another possible implementation, after receiving the QoS information, the access network device can perceive the local computing power state based on the computing management function, determine whether the local computing power state meets the computing power QoS requirements in the QoS information, and determine whether the requested service can be executed if the computing power QoS requirements are met, and determine the relevant configuration of the first wireless bearer used to carry service-related data based on the computing power QoS requirements and the data transmission QoS requirements in the QoS information, that is, the first configuration, such as completing the mapping between the QoS information and the wireless bearer configuration, and different wireless bearers are used to transmit data with different QoS requirements. Among them, the access network device locally configures the mapping relationship between the QoS information and the wireless bearer configuration parameters.

[0226] The first radio bearer may include at least one of the following: a data radio bearer (DRB), a signaling radio bearer (SRB), or a computing radio bearer (CRB). The DRB is used to transmit service-related data information, and the SRB is used to transmit service-related control information. Figure 4Under the protocol stack architecture shown in (a) and (b), SRB and CRB can be used to transmit service-related control information and / or data information. That is, the access network device can establish a DRB to transmit service-related data, and establish an SRB and / or CRB to transmit service-related control information, or the access network device may not establish a DRB to transmit service-related data information, and both data information and control information are transmitted by establishing an SRB and / or CRB. It should be understood that the first wireless bearer is mainly used to transmit service-related data information, but it does not exclude the transmission of other control information during the data transmission process.

[0227] Exemplarily, the QoS information corresponding to the service includes the requirements for the calculation accuracy of the access network device and the data transmission delay requirements. The access network device determines whether the calculation accuracy it has meets the requirements. If it does, it further establishes a wireless bearer according to the data transmission delay requirements and allocates resources for bearer transmission. If the data transmission delay requirement is shorter, more resources are allocated to the established wireless bearer for data transmission; if the data transmission delay requirement is longer, fewer resources are allocated to the established wireless bearer for data transmission.

[0228] As another example, the QoS information corresponding to the service includes the requirement for the calculation accuracy of the access network device. The access network device determines whether the calculation accuracy it possesses meets the requirement. If it does, it further establishes a wireless bearer according to the calculation accuracy requirement and allocates resources for bearer transmission. If the calculation accuracy requirement is high (implicitly indicating that the data is of high importance, or the calculation delay is large), more resources are allocated to the established wireless bearer for data transmission; if the calculation accuracy requirement is low (implicitly indicating that the data is of low importance, or the calculation delay is small), fewer resources are allocated to the established wireless bearer for data transmission. In this example, the calculation accuracy requirement can also be replaced by the calculation load requirement.

[0229] In another exemplary embodiment, the QoS information corresponding to the service includes the calculation delay requirement for the access network device. The access network device determines whether the calculation delay it has meets the requirement. If it does, it further establishes a wireless bearer according to the calculation delay requirement and allocates resources for bearer transmission. If the calculation delay requirement is shorter (implicitly indicating that the data transmission delay requirement is longer), fewer resources are allocated to the established wireless bearer for data transmission; if the calculation delay requirement is longer (implicitly indicating that the data transmission delay requirement is shorter), more resources are allocated to the established wireless bearer for data transmission.

[0230] As another example, the QoS information corresponding to the service includes the computing load requirements and data transmission delay requirements for the access network device. The access network device determines whether the computing load capacity it possesses meets the requirements. If it does, it further establishes a wireless bearer based on the computing load requirements and data transmission delay requirements, and allocates resources for bearer transmission. If the computing load requirement is large and the data transmission delay requirement is short, more resources are allocated to the established wireless bearer for data transmission; if the computing load requirement is small and the data transmission delay requirement is long, fewer resources are allocated to the established wireless bearer for data transmission.

[0231] In the scenario where only the user plane network element provides services for the terminal device, such as S703b above, the first radio bearer is used to transmit data related to the service provided by the user plane network element. At this time, the access network device can establish a radio bearer according to the QoS of the service provided by the user plane network element to the terminal device. Different from the scenario shown in S703a above, the QoS information used by the access network device to determine the configuration of the radio bearer is to ensure the service provided by the user plane network element.

[0232] In the scenario where both the user plane network element and the access network device provide services for the terminal device, such as including the above S703a and S703b, the first radio bearer includes a radio bearer for the service provided by the user plane network element and a radio bearer for the service provided by the access network device. At this time, the access network device will obtain the QoS information to ensure the services it provides and the QoS information to ensure the services provided by the user plane network element. The access network device can establish different radio bearers according to the QoS information of different services to transmit the relevant data of the service provided locally by the user plane network element to the terminal device, and transmit the relevant data of the service provided locally by the access network device to the terminal device.

[0233] In one possible design, the first configuration may be carried in an RRC message, such as an RRC setup message or an RRC reconfiguration message. In a scenario where the first radio bearer is a DRB, the first configuration may be carried in a DRB new modification list (drb-ToAddModList) information element in the RRC reconfiguration message.

[0234] In a possible design scheme, the access network device may send a second indication message to the session management network element, and accordingly, the session management network element receives the second indication message from the access network device. The second indication message is used to indicate that the first radio bearer for the service between the access network device and the terminal device is successfully established, and the second indication message may be carried in a PDU session resource establishment response message. Under this scheme, in a possible scenario, the second indication message may also be used to indicate that the first radio bearer for the service between the access network device and the terminal device fails to be established, such as due to limited or insufficient resources.

[0235] It should be understood that before the first radio bearer is established, a radio bearer for communication is also established between the terminal device and the access network device. Exemplarily, the first configuration is transmitted through the second radio bearer, and the second radio bearer is different from the first radio bearer. Before the first radio bearer is established, the transmission of control information such as indication information and configuration information between the terminal device and the access network device can be realized. The second radio bearer can be at least one of the following: a signaling radio bearer or a computing radio bearer.

[0236] In a possible design scheme, the second radio bearer may be a common signaling radio bearer or a common computing radio bearer, which is used to transmit all service-related control information, such as the first indication information sent by the terminal device, the first configuration sent by the access network device, etc. For example, the first configuration is carried in the RRC setup message (Msg4) and sent, and the common signaling radio bearer may be SRB 0 in NR. For another example, the first configuration is carried in the RRC reconfiguration message and sent, and the common signaling radio bearer may be SRB 1 in NR.

[0237] In one possible scenario, when the computing power status of the access network device does not meet the computing power QoS requirements, the access network device can sense the computing power status of other access network devices or user-plane network elements, and assign services to access network devices or user-plane network elements that meet the computing power QoS requirements, or negotiate with access network devices or user-plane network elements that meet the QoS requirements to allow them to provide services to terminal devices.

[0238] Exemplarily, if access network device #1 determines that its computing power status does not meet the computing power QoS requirement, and perceives that the computing power status of access network device #2 meets the computing power QoS requirement, it can send QoS information corresponding to the service and indication information #1 to access network device #2, and the indication information #1 is used to indicate that access network device #2 provides services for the terminal device. Optionally, indication information #1 may include the reason why access network device #1 cannot perform the service. Indication information #1 and indication information #2 can be carried in the Xn-C message.

[0239] Further, the access network device #1 may send indication information #2 to the terminal device to inform the terminal device that the access network device #2 provides services for it. And / or, the access network device #1 may send indication information #3 to the session management network element to inform that the access network device #2 provides services for the terminal device. The indication information #2 and / or the indication information #3 may also include the reason why the access network device #1 cannot perform the service.

[0240] It should be understood that no matter whether the user plane network element provides services for the terminal device or the access network device provides services for the terminal device, the access network device needs to determine the first configuration based on the QoS information and send the first configuration to the terminal device.

[0241] S705: The user plane network element sends the second configuration to the access network device. Correspondingly, the access network device receives the second configuration from the session management network element.

[0242] In the scenario where both the user plane network element and the access network device provide services for the terminal device, or in the scenario where only the user plane network element provides services for the terminal device, that is, when the user plane network element provides services for the terminal device, the user plane network element needs to establish a tunnel for the service with the access network device, such as a general packet radio service (GPRS) tunneling protocol user plane part protocol (GTP-U) tunnel, so the user plane network element can determine the second configuration according to the QoS information corresponding to the service, and send the second configuration to the access network device, the second configuration is used to configure the access network device to establish a tunnel for the service between the access network device and the user plane network element. The second configuration may include relevant configuration information such as routing priority, congestion avoidance, packet filtering, uplink or downlink rate control, etc.

[0243] It should be understood that S705 can be considered as an optional step, and S705 is not executed when the user plane network element does not provide services for the terminal device.

[0244] S706: The access network device sends service-related data information to the terminal device via the first radio bearer. Correspondingly, the terminal device receives service-related data information from the access network device via the first radio bearer.

[0245] In the case where the user plane network element locally provides services to the terminal device, the access network device can forward the relevant data information of the service provided by the user plane network element to the terminal device through the first wireless bearer, and the user plane network element can carry the relevant data information of the service in the GTP-U message and send it to the access network device. For example, if the user plane network element provides the rendering result of AR rendering to the terminal device, the user plane network element can send the rendering result to the access network device through the GTP-U message, and the access network device can parse the GTP-U message to obtain the rendering result of AR rendering, and send the rendering result to the terminal device through the first wireless bearer.

[0246] In the case where the access network device locally provides services for the terminal device, the access network device directly sends service-related data to the terminal device through the first radio bearer.

[0247] In the case where both the local access network device and the local user plane network element provide services to the terminal device, data related to the two services may also be sent to the terminal device via the first radio bearer.

[0248] It should be understood that in the embodiment of the present application, the terminal device may also send relevant data for the user plane network element or access network device to complete the service to the user plane network element or access network device. For example, if the service is that the access network device sends an AI training model to the terminal device, the terminal device may send sample data for AI model training to the access network device.

[0249] It should also be understood that, when both S703a and S703b exist, the embodiment of the present application does not limit the execution order of S703a and S703b, and the execution order of S704 and S705.

[0250] based on Figure 7 In the communication method shown, the session management network element obtains QoS information corresponding to the service provided by the access network device and / or the user plane network element to the terminal device according to the first indication information, and sends the QoS information to the access network device and / or the user plane network element, so that the access network device establishes a wireless bearer for the service between the access network device and the terminal device, and / or the user plane network element establishes a tunnel for the service between the access network device and the access network device. The demand for the access network device and / or the user plane network element to provide local services for the terminal device can be realized. Compared with the data network providing data services, the signaling interaction process is reduced, the service efficiency can be improved, and the node providing the service is closer to the user, which can reduce the transmission delay, improve the reliability and ensure the service quality.

[0251] Next, we will combine the 5G system Figure 7 The communication method shown is described in detail. Among them, the terminal device is UE, the access network device is gNB, the user plane network element is UPF, and the session management network element is SMF. The example in which both UPF and gNB provide services to UE is used for explanation.

[0252] For example, Figure 8 A flow chart of a communication method provided in an embodiment of the present application. Figure 8 As shown, the method comprises the following steps:

[0253] S801, UE sends a PDU Session Establishment Request message to SMF. Correspondingly, SMF receives the PDU Session Establishment Request message from UE.

[0254] The PDU session establishment request message carries the first indication information to instruct the gNB and UPF to provide services for the terminal device, such as the gNB providing the AI ​​reasoning model for the UE and the UPF providing the AR rendering result for the UE. For the relevant description of the first indication information, please refer to the relevant description in S701 above, which will not be repeated here.

[0255] After SMF obtains the first indication information, it negotiates with UDM to obtain the user subscription data information of the UE according to the service indicated by the first indication information, and obtains the QoS information corresponding to the service from PCF, such as the QoS information corresponding to the AI ​​reasoning model provided by gNB to the UE, including the requirements for the computing power of gNB to obtain the AI ​​reasoning model, and the latency requirements for transmitting the AI ​​reasoning model, and the QoS information corresponding to the AR rendering result provided by UPF to the UE, including the requirements for the computing accuracy of UPF to perform AR rendering, and the latency requirements for transmitting the AR rendering result.

[0256] Among them, the requirement for the computing power of gNB to obtain the AI ​​inference model may be the computing power requirement for gNB to calculate the AI ​​inference model, the delay requirement required to transmit the AI ​​inference model may be the delay requirement from gNB sending the AI ​​inference model to UE receiving the AI ​​inference model, the requirement for the computational accuracy of UPF performing AR rendering may refer to the accuracy requirement or precision requirement for the AR rendering result, and the delay requirement for transmitting the AR rendering result may refer to the delay requirement from UPF sending the AR rendering result to UE receiving the AR rendering result, that is, including the transmission delay requirement between UPF and gNB and the transmission delay requirement between gNB and UE.

[0257] Therefore, after SMF obtains the QoS information corresponding to the AI ​​reasoning model provided by gNB to the UE, and the QoS information corresponding to the AR rendering result provided by UPF to the UE, it sends them to gNB and UPF respectively, such as executing S802 and S803 below.

[0258] S802, SMF sends an N3 Tunnel Setup Request message to UPF. Correspondingly, UPF receives the N3 Tunnel Setup Request message from SMF.

[0259] Among them, the N3 tunnel establishment request message carries the QoS information corresponding to the result of AR rendering provided by UPF to UE. Therefore, UPF can judge whether its calculation accuracy meets the requirements according to the calculation accuracy requirements in the QoS information. If the calculation accuracy meets the requirements, it determines the configuration information such as routing rules and congestion avoidance according to the latency requirements in the QoS information.

[0260] S803. SMF sends a PDU Session Resource Setup Request message to gNB. Correspondingly, gNB receives the session resource setup request message from SMF.

[0261] Among them, the PDU session resource establishment request message includes the QoS information corresponding to the AI ​​reasoning model provided by the gNB to the UE. Since the UPF needs to provide services to the UE, the message may also carry the QoS information corresponding to the result of the AR rendering provided by the UPF to the UE. Therefore, the gNB can establish different radio bearers according to the QoS information of different services to complete the data transmission of different services.

[0262] S804. UPF and gNB establish N3 tunnel.

[0263] Exemplarily, the UPF may send relevant configuration information for tunnel establishment determined according to QoS information to the gNB to complete the establishment of the N3 tunnel for transmission of AR rendering results between the gNB and the UPF.

[0264] S805. The gNB sends an RRC Reconfiguration message to the UE. Correspondingly, the UE receives the RRC Reconfiguration message from the gNB.

[0265] The RRC reconfiguration message includes the radio bearer configuration for transmitting the result of AR rendering and the radio bearer configuration for transmitting the AI ​​reasoning model. After receiving the radio bearer configuration, the UE can complete the establishment of the radio bearer for transmitting the result of AR rendering and the radio bearer for transmitting the AI ​​reasoning model with the gNB based on the radio bearer configuration.

[0266] S806. The UE sends an RRC Reconfiguration Complete message to the gNB. Correspondingly, the gNB receives the RRC Reconfiguration Complete message from the UE.

[0267] Among them, the RRC reconfiguration completion message includes indication information #1 and indication information #2, indication information #1 is used to instruct the UE to complete the establishment of a wireless bearer for the transmission of AR rendering results, and indication information #2 is used to instruct the UE to complete the establishment of a wireless bearer for the transmission of AI reasoning models.

[0268] S807. gNB sends a PDU Session Resource Setup Response message to SMF. Correspondingly, SMF receives the PDU Session Resource Setup Response message from gNB.

[0269] Among them, the PDU session resource establishment response message carries indication information #3 and indication information #4. Indication information #3 is used to indicate that the wireless bearer for transmission of AR rendering results between the gNB and the UE is successfully established, and indication information #4 is used to indicate that the wireless bearer for transmission of AI reasoning models between the gNB and the UE is successfully established.

[0270] That is to say, after the gNB completes the establishment of the radio bearer for the transmission of AR rendering results and the AI ​​reasoning model, it can inform the SMF that it has completed the establishment of the radio bearer for the service.

[0271] Therefore, after gNB and UPF complete the establishment of wireless bearer and tunnel, they can send the AR rendering results and AI reasoning model to the UE.

[0272] It should be understood that the embodiment of the present application does not limit the execution order of the above S802 and S803, and the execution order of S804 and S805.

[0273] Above Figure 8 The figure shows the interaction process in which the UE triggers the SMF to obtain QoS information based on the PDU session request to instruct the gNB and UPF to provide local services. In addition, the UE can also directly trigger the gNB and / or UPF to provide local services.

[0274] For example, Fig. 9 A flow chart of a communication method provided in an embodiment of the present application. Fig. 9 As shown, the method comprises the following steps:

[0275] S901. The terminal device sends first indication information.

[0276] In a possible design scheme, the terminal device sends the first indication information to the session management network element. Correspondingly, the session management network element receives the first indication information from the terminal device. Under this design scheme, the specific description of the first indication information and the process of the access network device and / or the user plane network element providing local services can be referred to the relevant description in S701 to S706 above, which will not be repeated here.

[0277] In another possible design, the terminal device sends the first indication information to the access network device. Correspondingly, the access network device receives the first indication information from the terminal device. In this design, the terminal device directly triggers the access network device to provide local services. Fig. 9 The communication process shown is mainly for the process in which the terminal device directly triggers the access network device to provide services.

[0278] Under this design, the first indication information can be carried in an RRC message. For example, during the initial random access process of the terminal device, the terminal device carries the first indication information in an RRC Setup Request message (initial access Msg3). For another example, after the terminal device performs random access, the first indication information is carried in an RRC Setup Complete message (Msg5).

[0279] Under this design scheme, the terminal device can also send QoS information corresponding to the service to the access network device. Correspondingly, the access network device receives the QoS information corresponding to the service from the terminal device. In other words, the terminal device can configure the QoS information of the required service to instruct the access network device to establish a wireless bearer for the service. The specific description of the QoS information corresponding to the service can be found in the relevant description in S702 above, which will not be repeated here.

[0280] In a possible implementation, the first indication information and the QoS information may be carried in the same message, such as the first indication information and the QoS information are carried in an RRC establishment request and sent to reduce signaling overhead.

[0281] In a possible implementation, the access network device and the terminal device may include a computing resource control entity, such as Figure 4 In the CRC layer of the protocol stack architecture shown in (a) or (c), the computing resource control entity is used to process control information and / or data information related to the service. At this time, the first indication information can be carried in the CRC message and sent.

[0282] Similarly, the terminal device may also send first indication information to the user plane network element to instruct the user plane network element to provide local services for it. It should be understood that when the terminal device sends the first indication information to the user plane network element, the first indication information may be forwarded to the user plane network element through the access network device.

[0283] S902: The access network device sends a first configuration to the terminal device. Correspondingly, the terminal device receives the first configuration from the access network device.

[0284] The access network device determines the first configuration according to the QoS information corresponding to the service. For the specific description of S902, reference may be made to the relevant description in the above S704, which will not be repeated here.

[0285] When the terminal device sends the first indication information to the session management network element, the access network device receives the QoS information corresponding to the service from the session management network element, and determines the first configuration according to the QoS information. The specific implementation process of the access network device obtaining the QoS information from the session management network element can refer to the relevant description in S702 and S703 above, which will not be repeated here.

[0286] When the terminal device sends the first indication information to the access network device, the access network device receives QoS information corresponding to the service from the terminal device and determines the first configuration according to the QoS information.

[0287] S903: The access network device sends service-related data information to the terminal device via the first radio bearer. Correspondingly, the terminal device receives service-related data information from the access network device via the first radio bearer.

[0288] Among them, the specific description of S903 can refer to the relevant description in the above S706, which will not be repeated here.

[0289] based on Fig. 9 In the communication method shown, the terminal device can directly or indirectly trigger the access network device and / or the user-side network element to provide local services by sending a first indication message. The node providing the service is closer to the user, which can reduce transmission delay, improve reliability and ensure service quality.

[0290] Next, we will combine the 5G system Fig. 9 The communication method shown is described in detail. Among them, the terminal device is UE, the access network device is gNB, and the result of AI rendering provided by gNB locally to UE is described as an example.

[0291] For example, Fig.10 A flow chart of a communication method provided in an embodiment of the present application. Fig.10 As shown, the method comprises the following steps:

[0292] S1001. The UE sends a computing service request to the gNB. Correspondingly, the gNB receives the computing service request from the UE.

[0293] The computing service request includes first indication information and QoS information corresponding to the service, the first indication information is used to indicate the service provided by the gNB to the UE, such as the result of AI rendering provided by the gNB to the UE, and the QoS information corresponding to the service includes the requirements for the calculation accuracy of the UPF performing AR rendering and the latency requirements for transmitting the result of AR rendering. For example, the computing service request may be an RRC Setup Request (Msg3) message, transmitted via SRB0, or the computing service request may be an RRC Setup Complete (Msg5) message, transmitted via SRB1.

[0294] S1002. The gNB sends a computing service response to the UE. Correspondingly, the UE receives the computing service response from the gNB.

[0295] The computing service response includes a first configuration, and the first configuration is used for the UE to establish a first radio bearer, such as an SRB, a DRB, or a CRB, between the UE and the gNB for transmitting the result of AR rendering. For example, the computing service response may be an RRC Setup message, which is transmitted via SRB0, or the computing service response may be an RRC Reconfiguration message, which is transmitted via SRB1.

[0296] For a detailed description of the first configuration in S1002, reference may be made to the related description in S704 above, which will not be repeated here.

[0297] S1003, gNB and UE transmit service-related data information through the first radio bearer.

[0298] Exemplarily, after the first radio bearer is established between the gNB and the UE, the gNB may send the AR rendering result to the UE through the first radio bearer.

[0299] based on Fig.10 In the communication method shown, the UE sends a first indication message to the gNB to trigger the gNB to provide local services for the terminal device.
