[0097] Before introducing the technical solutions of the embodiments of the present application, the related technologies are first introduced.

[0098] At present, in the digital era of the Internet of Everything, computing and communication have become the core basic capabilities that enable the digital and intelligent transformation of the industry. Operators have proposed the concept of cloud-network integration and further evolved towards computing-network integration to achieve a new information service system of "connection + computing power + capability" based on basic connection services, promote the realization of ubiquitous networks, ubiquitous computing power, and all-encompassing intelligence, prosper the digital economy, and create a smart computing future. The amount of data brought by emerging technologies, applications, and scenarios continues to grow, and all walks of life have put forward more urgent demands on computing power and networks. In terms of computing power demand, my country's total computing power in 2020 has reached 135EFLOPS (EFLOPS refers to 100 billion floating-point operations per second), a year-on-year increase of 55%, exceeding the global growth rate by about 16 percentage points. In terms of network demand, business upgrades have put forward higher speed, lower latency, and wider coverage requirements for the network. Taking the unmanned driving scenario as an example, from 2018 to 2030, the demand for computing power for unmanned driving will increase 390 times. In the future, the demand for network bandwidth at the L4 and L5 levels will be greater than 100Mbps, and the latency requirement will reach 5-10 milliseconds. In the digital currency scenario, the computing power demand in 2030 will increase by about 2,000 times compared with 2018; the computing power demand for VR games will increase by about 300 times, and the end-to-end latency must be at least less than 20 milliseconds. In the above scenarios, business scenarios such as unmanned driving and VR have very high requirements for computing and networks. Considering the requirements of low latency, large bandwidth and large computing power, it is necessary to consider the full utilization of wireless edge computing power networks and the efficient coordination and computing power flow of cloud, edge and end computing power and networks to meet the business's demand for on-demand use of computing power. At the same time, with the extreme requirements of industry applications for end-to-end network quality, the network needs to evolve from best efforts to end-to-end deterministic guarantee, and network protocols also need to be innovatively developed.

[0099] With the gradual integration of wireless communication technology (CT) and Internet technology (IT), 5G wireless is also gradually evolving towards cloud computing, and traditional dedicated hardware is evolving towards general-purpose servers. The hardware resources of traditional wireless dedicated base stations will also gradually evolve towards the cloud platform on the wireless side by adding accelerator boards, supporting the deployment of wireless data plane and control plane functions, and agilely deploying local field-level or edge business applications. Based on the cloud base on the wireless side, the wireless side also has the ability to support diversified computing resources and the ability to support unified computing power orchestration and scheduling.

[0100] With the continuous development of new businesses such as smart services, XR, metaverse immersive services, Internet of Vehicles and Internet of Things, smart terminals are not only more diversified in product form (such as wearable devices, smart homes, IoT and vehicle-mounted equipment, etc.), but also benefit from the continuous maturity of semiconductor technology and the introduction of AI chips. The computing power of terminals has also developed rapidly. In a network with deep integration of communication and computing, edge-end collaboration has been further extended from the usual collaboration between terminals and edge clouds to the collaboration between terminals and base stations. In addition to providing connection services, base stations further provide computing services. Smart terminals have characteristics such as resource constraints (such as computing power is limited by the size of battery capacity) and computing power differences (the same type of terminals have different computing power due to different chips). Using edge computing to offload terminal computing tasks has become a major research direction in the industry.

[0101] Edge computing (MEC) is one of the effective methods to reduce the service access latency of terminals. From the perspective of service latency, the latency of terminal access to MEC includes not only the air interface latency but also the transmission latency of the backhaul network. In URLLC service scenarios, such as the Internet of Vehicles service, the latency constraints are extremely strict. If MEC cannot meet the service latency requirements, it is necessary to reselect the MEC site or increase MEC deployment, which will greatly increase the network construction and MEC room operation and maintenance costs. Compared with MEC, since base stations are more widely distributed, the use of base stations to share computing resources to offload terminal computing requirements can support widely distributed terminals; from the perspective of latency, the air interface latency of the terminal accessing the base station is less than the time for the terminal to access the MEC (adding the backhaul latency of accessing the core network and MEC on the basis of the air interface latency). The base station can share computing resources for deploying service applications, which has a greater service latency advantage than MEC. Base station computing resources are shared. On the wireless network side, base stations have the characteristics of wide coverage and deep connection, providing low-latency connection services for terminals. Base stations have been regarded as a form of edge computing.

[0102] However, there is no corresponding mechanism for how base stations provide computing services and enable terminals to perceive the computing service capabilities of base stations and complete computing service access. In 5G networks, the service application function (AF) is the interaction medium between business applications and 5G networks. AF can obtain data in the network through NEF (such as QoS information of a certain application call, UE location information, TSN information, flow control information, multicast information, etc.) and provide operations (update service parameters, create flow control actions, etc.). AF actively makes adjustments for business applications to obtain better connections. In the case where base station computing power can be shared as a service, there is no research in the relevant technology on how the computing power on the wireless side can provide services to business applications.

[0103] Based on this, in an embodiment of the present application, the network device sends first information and / or second information to the application function; wherein the first information represents computing resource information, and the computing resource information is used to provide the computing service to the application function; the second information represents interface information of the computing function deployed on the network device, and the interface information is used to provide the computing service to the application function by providing the computing function to the application function.

[0104] See also Figure 1 , Figure 1 Schematic diagram of the implementation flow of the information transmission method of the embodiment of the present application, which is applied to network devices such as Figure 1 As shown, the method comprises step 101:

[0105] Step 101: Sending first information and / or second information to an application function;

[0106] Among them, the first information represents computing resource information, and the computing resource information is used to provide the computing service to the application function; the second information represents interface information of the computing function deployed on the network device, and the interface information is used to provide the computing service to the application function by providing the computing function to the application function.

[0107] As an example, the network device may include a base station or the like.

[0108] As an example, the computing resources mainly come from:

[0109] The computing resources not used by the wireless protocol stack when the macro station service is idle;

[0110] Computing resources for macro site expansion, such as computing boards;

[0111] Shared computing resources for cloud-based base station infrastructure.

[0112] As an example, taking the network device as a base station, the manner in which the base station provides computing services to the AF may include the following two manners:

[0113] The first method is to provide computing resource services, which means that the base station can provide computing services in the form of computing resources.

[0114] For example, the base station provides shared computing resource information, such as the number of CPUs, main frequency, storage capacity, GPU capacity, and other computing resource information, and AF uses it on demand. The base station encapsulates computing resources into computing units with certain hardware specifications, such as virtual machines and containers, and AF selects the computing units provided by the base station on demand.

[0115] Considering the reuse of computing resources of base stations and wireless protocol stacks, computing resources can be provided at the same time: available time, geographic location and other information to assist AF in selecting computing services.

[0116] The second method, providing computing task-based services, means that the base station has completed the deployment of computing functions, and the AF uses the computing functions on demand.

[0117] For example, if the base station has deployed an AIML model, AF can use the deployed intelligent application for training and reasoning. At this time, the base station computing service can provide corresponding network interfaces or APIs for training data and reasoning data, so that AF can specify the input parameters of the model and obtain the output parameters. In this scenario, the base station provides parameters such as model type, model accuracy, and computing latency for the AIML service provided.

[0118] The base station deploys a graphics rendering application and provides an API interface to the AF, which can use the image rendering service on demand. For example, if the AF senses that the UE's battery power is decreasing, it continues to render images locally to reduce the battery power faster. The AF uses the image rendering application provided by the base station and notifies the UE to access the base station's rendering service to achieve end-to-end computing collaboration.

[0119] The following is a detailed description of the implementation process of the network device sending the first information and / or the second information to the application function.

[0120] In the first case, the network device provides computing-related information to the outside through the core network.

[0121] In some embodiments, sending the first information and / or the second information to the application function includes:

[0122] The first information and / or the second information is sent to a first network function, and the first network function sends the first information and / or the second information to the application function via a second network function.

[0123] In some embodiments, sending the first information and / or the second information to the first network function includes:

[0124] Encapsulating the first information and / or the second information into a first message between the network device and the first network function; the first message is an NG interface application protocol NGAP message, or a message obtained by extending the NGAP message;

[0125] The first message is sent to the first network function.

[0126] See also Figure 2 , Figure 2 Schematic diagram of the implementation process of the network device providing computing services to the AF in the embodiment of the present application, such as Figure 2 As shown, taking the network device as a base station, the first network device as an AMF, and the second network device as an NEF as an example, the process of the base station providing a computing service to the AF may include:

[0127] Step 1: The base station encapsulates the computing resource information, i.e., the first information, and / or the computing task service information, i.e., the second information, into a first message, and sends the first message to the AMF.

[0128] Here, the first message may be an existing NGAP message or a newly defined NGAP message.

[0129] Here, the base station has the ability to share computing resources. The base station connects to the AMF through the N2 interface, and the AMF provides the base station computing related information to the AF through the NEF. Therefore, the NG interface signaling between the base station and the AMF needs to be extended accordingly so that the base station and the AMF can transmit computing related information, that is, the existing NGAP message can be used for transmission, and the new NGAP message can also be used to transmit the base station computing information.

[0130] Step 2: After receiving the first message sent by the base station, the AMF obtains the calculation-related information of the base station carried in the first message, namely, the first information and / or the second information, encapsulates the calculation-related information of the base station, namely, the first information and / or the second information, into a second message between the AMF and the NEF, and transmits the second message to the NEF.

[0131] Here, NEF adds computing information services and / or computing task services.

[0132] Step 3: NEF sends the second message to AF, and AF obtains the first information and / or the second information through the second message sent by NEF, and obtains the computing service provided by the base station according to the first information and / or the second information.

[0133] In some embodiments, sending the first information and / or the second information to the application function includes:

[0134] receiving, through the second network function, a first request sent by the application function, wherein the first request is used to request first information and / or second information that satisfies a subscription constraint condition;

[0135] The second network function responds to the first request and sends the first information and / or the second information that meets the subscription constraint condition to the application function.

[0136] In some embodiments, sending the first information and / or the second information satisfying the subscription constraint condition to the application function through the second network function includes:

[0137] In a case where the second network function stores the first information and / or the second information satisfying the subscription constraint condition, sending the first information and / or the second information satisfying the subscription constraint condition to the application function through the second network function;

[0138] or,

[0139] In a case where the second network function does not store the first information and / or the second information satisfying the subscription constraint condition, the second network function interacts with the network device to send the first information and / or the second information satisfying the subscription constraint condition to the application function.

[0140] In some embodiments, the first network function is AMF and the second network function is NEF.

[0141] See also Figure 3 , Figure 3 Schematic diagram of the implementation process of the network device providing computing services to the AF in the embodiment of the present application, such as Figure 3 As shown, taking the network device as a base station, the first network device as an AMF, and the second network device as an NEF as an example, the process of the base station providing a computing service to the AF may include:

[0142] Step 1: AF subscribes to computing services through NEF.

[0143] Specifically, the AF sends a first request to the NEF; the first request is used to request to obtain computing resource information that meets the subscription constraint condition, namely the first information and / or computing task service information, namely the second information.

[0144] Here, the AF can subscribe to the computing service of the base station according to the location area and the available duration. The subscription can set subscription constraints, for example, subscribing to the computing information of the base station in a certain location area, the computing service that can be provided for a certain duration, and so on.

[0145] Step 2: The NEF provides the first information and / or the second information to the AF.

[0146] Specifically, after the NEF receives the subscription request from the AF to obtain the first information and / or the second information, if the NEF already has relevant calculation information locally, the NEF can provide it to the AF. If the NEF does not have the calculation information requested by the AF, the NEF obtains the calculation information of a certain area and a certain available duration requested by the AF through the interaction within the core network and the interaction between the core network AMF and the base station.

[0147] Optionally, the base station actively provides it to AMF and NEF, or AMF and NEF query whether the base station has computing capacity to provide, and if so, instruct the base station to report; or, based on AF subscription, AMF and NEF subscribe to computing information from the base station.

[0148] At the same time, when the computing resources and status of the base station change, it is necessary to report to AMF and NEF to update the computing information and computing service status in a timely manner.

[0149] In the second case, the network device provides computing-related information to the outside through the orchestration system.

[0150] In some embodiments, sending the first information and / or the second information to the application function includes:

[0151] Sending the first information and / or the second information to an orchestration system of the network device;

[0152] A first service is provided to a third network function through the orchestration system of the network device, so that the third network function sends the first information and / or the second information to the application function.

[0153] In some embodiments, the first service includes:

[0154] acquiring the first information and / or the second information;

[0155] and / or,

[0156] subscription to the first information and / or the second information;

[0157] and / or,

[0158] Use of Computing Services.

[0159] See also Figure 4 , Figure 4 Schematic diagram of the implementation process of the network device providing computing services to the AF in the embodiment of the present application, such as Figure 4 As shown, taking the network device as a base station and the third network device as an NEF as an example, the process of the base station providing computing services to the AF may include:

[0160] Step 1: The orchestration system of the base station is connected to the core network bus or an interface is added between the orchestration system of the base station and the NEF. The orchestration system of the base station provides the first service to the NEF, and the NEF consumes the service.

[0161] The first service includes but is not limited to:

[0162] subscription to the first information and / or the second information;

[0163] Acquisition of the first information and / or the second information;

[0164] Use of computing services;

[0165] Here, the use of computing services may refer to deploying applications on a certain base station computing resource, or using services provided by a certain computing task.

[0166] Here, the base station interacts with the NEF through the orchestration system to provide the base station calculation information, namely the first information and / or the second information. In this way, an interface needs to be established between the base station orchestration system and the NEF, and the NEF obtains the base station calculation information from the base station orchestration system and further provides it to the AF.

[0167] Here, the base station orchestration system provides a service interface to the outside world as a service provider. NEF, as a service consumer, connects to the base station orchestration system and consumes the computing services provided by the base station. The computing-related services provided by the base station orchestration system include but are not limited to: providing consumers with computing-related information acquisition, providing consumers with computing-related information subscription, providing consumers with computing service usage, etc.

[0168] Step 2: The NEF provides the AF with the calculation information of the base station, that is, the first information and / or the second information.

[0169] In some embodiments, sending the first information and / or the second information to the application function includes:

[0228] Step 0: The terminal accesses the service application provided by AF.

[0229] Step 1: AF subscribes to the Nnef_AF_request_for_QoS service provided by NEF to monitor the service quality of the terminal.

[0230] Step 2: AF believes that the QoS quality of the terminal service has deteriorated, and can deploy the application by sinking the application to a computing node closer to the terminal.

[0245] Step 13: The base station deploys the computing task according to the computing service request of the AF. For example, the AF carries the service application image and the image address, and the base station obtains the image to complete the deployment.
