Technical Field

[0002] This application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Technology

[0003] With the standardization of computing devices and algorithm models, and the maturation of software technologies such as artificial intelligence and cloud computing, the amount of data has exploded, leading to a surge in computing power demand and consequently, uneven distribution of computing resources. To address this issue, utilizing networks to schedule and allocate computing resources has become a current trend. In the current technological context, computing-first networking (CFN) can be used to schedule and / or allocate computing resources, routing computing tasks requested by terminal devices to the most suitable computing nodes through computing power routing.

[0004] In future communication systems, cloud edge nodes may be further moved down to or close to the access network, allowing access nodes to take on additional computing functions. After the computing function nodes are moved down, a star topology is typically used, meaning access nodes can connect to different computing function nodes and provide access services to multiple terminal devices. In this network structure, the discovery of computing nodes is a crucial consideration. Summary of the Invention

In future communication systems, the session management network element can still be an SMF network element, or it can have other names; this application does not limit this.

[0098] Slice selection network element 180: Used to select a set of network slice instances for the service terminal device, and to determine a set of access management network elements for the service terminal device.

[0099] In 5G communication systems, this open network element can be a network slice selection function (NSSF) element. In future communication systems, the open network element can still be an NSSF element, or it can have other names; this application does not limit its scope.

[0100] Network Exposure Element 190: Used to expose network capabilities to third-party applications, enabling a friendly connection between network capabilities and business needs.

[0101] In 5G communication systems, this network open element can be a network exposure function (NEF) element. In future communication systems, the network open element can still be a NEF element, or it can have other names; this application does not limit this.

[0102] Network repository (Network element 1100): Used to maintain real-time information for all network function services in the network.

[0103] In 5G communication systems, this network storage element can be a network repository function (NRF) element. In future communication systems, the network storage element can still be an NRF element, or it can have other names; this application does not limit its scope.

[0104] Policy control network element 1110: A unified policy framework used to guide network behavior, providing policy rule information to control plane functional network elements (such as AMF, SMF, etc.).

[0105] In 4G communication systems, this policy control network element can be a policy and charging rules function (PCRF) network element. In 5G communication systems, this policy control network element can be a policy control function (PCF) network element. In future communication systems, the policy control network element can still be a PCF network element, or it can have other names; this application does not limit this.

[0106] Data management network element 1120: Used to handle terminal device identification, access authentication, registration and mobility management, etc.

[0107] In 5G communication systems, this data management network element can be a unified data management (UDM) network element. In future communication systems, the unified data management network element can still be a UDM network element, or it can have other names; this application does not limit this.

[0108] Application network element 1130: Used for data routing affected by applications, network access, and policy control through interaction with the policy framework.

[0109] In 5G communication systems, this application network element can be an application function (AF) network element. In future communication systems, the application network element can still be an AF network element, or it can have other names; this application does not limit this.

[0110] The network architecture described above may also include authentication credential repository and processing (ARPF) network elements and security anchor function (SEAF) network elements (not shown in the figure). ARPF is primarily used to store the user's root key and related authentication subscription data, and to calculate authentication and authorization vectors. SEAF is mainly used to deduce the lower-level non-access stratum (NAS) and access stratum (AS) keys based on the anchor key, and to compare authentication results.

[0111] In the above network architecture, N1, N2, N3, N4, N6, Nnssf, Nnef, Nnrf, Npcf, Nudm, Naf, Nausf, Namf, and Nsmf are interface sequence numbers. The meanings of these interface sequence numbers can be found in the definitions provided in the 3GPP standard protocols; this application does not impose any limitations on the meanings of these interface sequence numbers.

[0112] For example, the N2 interface is the interface between the RAN and the access management network element, used for transmitting radio parameters, NAS signaling, etc.; the N3 interface is the interface between the RAN and the user plane function network element, used for transmitting user plane data, etc.; the N4 interface is the interface between the session management function network element and the user plane function network element, used for transmitting information such as service policies, tunnel identification information for N3 connections, data buffer indication information, and downlink data notification messages, etc.; the N6 interface is the interface between the DN and the user plane function network element, used for transmitting user plane data, etc.

[0113] Nnssf, Nnef, Nnrf, Npcf, Nudm, Naf, Nausf, Namf, and Nsmf are service interfaces, through which network elements can exchange information.

[0114] It should be understood that the interface names between the various network functions in the diagram are merely examples. In a specific implementation, the interface names of this system architecture may be other names, and this application does not limit them. Furthermore, the names of the messages (or signaling) transmitted between the aforementioned network elements are also merely examples and do not constitute any limitation on the function of the messages themselves.

[0115] It should also be understood that the network architecture described above in the embodiments of this application is merely an example of a network architecture described from the perspective of a traditional point-to-point architecture and a service-oriented architecture. The network architecture applicable to the embodiments of this application is not limited to this, and any network architecture that can realize the functions of the above-mentioned network elements is applicable to the embodiments of this application.

[0116] It should also be understood that the names of the various network elements and interfaces in this application are merely examples, and this application does not preclude the possibility of using other names for the various network elements in the future, or the possibility of merging the functions of various network elements. As communication systems evolve, any device or network element capable of implementing the functions of the aforementioned network elements is within the protection scope of this application.

[0117] It is understood that the aforementioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). These network elements or functions can be divided into one or more services; furthermore, services that exist independently of network functions may also emerge.

[0118] To facilitate understanding of the technical solutions of the embodiments of this application, some terms or concepts that may be involved in the embodiments of this application are briefly described.

[0119] 1. Computing Power Functions: A method of running code snippets (functions) as services without requiring the developer to manage servers and infrastructure. Developers only need to write business logic code, upload it to the function computing platform provided by a cloud service provider, and can quickly deploy and run applications. It is a serverless computing model, typically consisting of a series of configurations and a series of executable code / packages. The business logic code is the software program code written to support the computational processing of input data or events according to a specified algorithm. For example, the aforementioned computational processing may include: video stream transcoding, image rendering, image detection, artificial intelligence (AI) computation, etc.

[0120] 2. Computing Power Service: Also known as a computing service, this refers to an independent application process that implements a set of or a specific computing function. Computing power services can communicate using a lightweight application programming interface (API) through a well-defined interface. Generally, the functionality implemented by a computing power function can be encapsulated as a service and provided to external entities for invocation via the API. One computing power service can correspond to one or more computing power functions providing the same functionality; that is, multiple different computing power functions implement the same function and provide the same computing power service. The computing power (or computing function) of a computing node or computing unit can be understood as its ability to provide computing resources to a computing service.

[0121] 3. Computing Power Service Instance: A service instance can be understood as an entity that can provide computing power services. For example, it can be hosted by a container. This container has the runtime environment for the computing power service, can process the input of the computing power service, execute code logic, and obtain output results. A computing power service instance can also be called a computing power function instance or a computing service instance.

[0122] 4. Computation Task: Also known as a computing power task, this refers to executing a computing power function call (invoke) or obtaining a result from a computing power service to complete a business logic transaction. For example, in the case of video transcoding of specified data, for a video clip or video chip, a computing power service call can be executed, using that video clip or video chip as input to the computing power service, until the computing power service runs and obtains the transcoded clip or chip, which constitutes executing one computation task.

[0123] 5. Service Level Agreement (SLA) Requirements for Computing Power Services: These requirements indicate the computing performance that the computing power service needs to provide. For example, SLA requirements can indicate the latency required for a function instance to execute a computing task. If the computing task is an image rendering task, the latency required to execute the computing task can be the time required to render one frame. Alternatively, SLA requirements can also indicate the computing and communication performance that the computing power service needs to provide. For example, SLA requirements can indicate the total latency from when the terminal device sends a computing task request to when the terminal device receives the computing task execution result. If the computing task is an image rendering task, the total latency can be the total time from when the terminal device sends an image rendering request to when the terminal device receives the image rendering result.

[0124] 6. Computing Function Node: Also known as a computing power node or computing node, it is a device or functional unit that has computing capabilities or can provide computing power services.

[0125] 7. Service-Oriented Interface: This interface is specific to a single functional entity. This functional entity interacts with other functional entities through the service-oriented interface exposed by the functional entity. Other functional entities interact with this functional entity through the service-oriented interface exposed by the functional entity. The functional entity can be a functional module within a network entity, such as a terminal device, an access node (more specifically, a RU, DU, or CU within the access node), an AMF, an NRF, or an entity that provides (or carries) function instances.

[0126] 8. Reference point: refers to the interface agreed upon between two functional entities for mutual access. The reference point between two functional entities can generally be replaced by one or more service interfaces (or interfaces).

[0127] In future communication systems, cloud edge nodes may be further moved down to the network access network (i.e., the RAN side). Therefore, the access network can also take on some computing functions. These computing functions can be internal functions of the RAN node or external independent functions that are separate from the logical functions of the RAN node.

[0128] Figure 2 shows a schematic block diagram of a system architecture applicable to this application. As shown in Figure 2, the system includes an access node 20, a computing unit 30, and a core network 40. Optionally, the system also includes a terminal device 10 and / or a management module 50.

[0129] Access node 20 provides access services to terminal device 10 and has the ability to schedule computing services and / or allocate computing resources for terminal device 10. Terminal device 10 and access node 20 can be referenced respectively to the descriptions of terminal device 110 and RAN node 120 in the above network architecture.

[0130] The computing unit 30 can be used to provide specific computing services or computing power services, such as providing low-latency, short-connection services to the terminal device 10. The computing unit 30 can have a reference point with one or more computing services requested by the terminal device 10, and can provide computing resources to the terminal device 10 through this reference point. The computing unit 30 can also have data storage capabilities. The computing unit 30 may only have the ability to perform calculations and send and receive computing service-related information with the access node 20, without the ability to provide access services to the terminal device; alternatively, the computing unit 30 may also have both computing and communication capabilities. The computing unit 30 can be one of the aforementioned computing function nodes.

[0131] In some implementations, a communication connection may exist between the computing unit 30 and the access node 20. This communication connection can be a direct connection, such as a zero-hop direct connection, meaning that no other network devices participate in data forwarding along the communication path between the computing unit 30 and the access node 20, and the two belong to the same local area network, or the same virtual local area network, or have a direct connection at the same protocol layer.

[0132] Alternatively, the communication connection may be an indirect connection, that is, the computing unit 30 and the access node 20 may be connected through other network devices (denoted as network device #1), or the computing unit 30 may be directly connected to the network device #1, and the access node 20 may be connected to the computing unit 30 through the network device #1.

[0133] In the case of an indirect communication connection, since the computing unit 30 is directly connected to the network device #1, the solution provided in this application embodiment can be applied to the network device #1. In other words, the access node mentioned in the solution of this application embodiment can refer to a node that provides access services to the terminal device (e.g., a RAN node), or the access node can refer to a node (network device, functional entity, or network element) that is directly connected to the computing unit, such as network device #1.

[0134] As an example, network device #1 is a user plane network element, such as a UPF. This user plane network element and access node 20 can be separate functional entities (network elements), or the user plane network element and access node 20 can be co-located (i.e., the same functional entity / network element). It should be understood that when the user plane network element and access node 20 are co-located, the communication connection can also be regarded as a direct connection without limitation.

[0135] As another example, network device #1 is a gateway. That is, the gateway can forward data between access node 20 and computing unit 30 based on the destination address and routing information.

[0136] Furthermore, the existence of a communication connection between the computing unit 30 and the access node 20 can also be understood as the communication latency between the computing unit 30 and the access node 20 meeting the latency requirements, for example, the communication latency between the computing unit 30 and the access node 20 being less than or equal to the latency threshold.

[0137] The core network 40 may include core network elements and computing unit control nodes. For example, core network elements include session management network elements (such as SMF), access management network elements (such as AMF), and control plane function network elements (such as XCF, which can be implemented by one or more of the existing AMF, SMF, and PCF). In addition, the core network 40 may also include Network Exposure Function (NEF) network elements for exposing core network 40 data to the outside world. See Figure 1 for details. The computing unit control nodes can be used to manage computing units, such as receiving computing unit registrations, address (e.g., Internet Protocol (IP) address) allocations, QoS, and configuring computing services to access nodes. The computing unit control node can be a single entity or multiple entities distributed across different geographical locations. In some implementations, the computing unit control node can be co-located with core network elements (such as SMF).

[0138] The communication methods between the computing unit control node and the access node 20 and computing unit 30 may include the following:

[0139] 1) The computing unit control node and the access node 20 can communicate through a direct reference point; the computing unit control node and the computing unit 30 can communicate through a direct reference point.

[0140] 2) The computing unit control node can communicate with the access node 20 through the AMF, and the AMF and the access node 20 can communicate with each other through a direct reference point; the computing unit control node and the computing unit 30 can communicate with each other through a direct reference point.

[0141] 3) The computing unit control node can also communicate with the access node 20 and the computing unit 30 based on a service-based architecture (SBA), that is, the computing unit control node communicates with the access node 20 and the computing unit 30 through the SBA bus mechanism. Optionally, the computing unit control node and the access node 20 can also communicate through a direct connection reference point.

[0142] 4) The computing unit control node can also be set in the access node 20, and there is a direct connection reference point between the access node 20 and the computing unit 30. The computing unit control node communicates with the computing unit 30 through the above-mentioned direct connection reference point.

[0143] For example, the aforementioned direct connection reference point can be a reference point based on the next generation application protocol (NG-AP), or a reference point based on a non-access stratum (NAS) protocol, or a service interface protocol based on Hypertext Transfer Protocol (HTTP) 1 / 2 / 3.

[0144] The aforementioned reference point can also be understood as an interface. The existence of a direct connection reference point or direct connection interface between two nodes can be understood as a zero-hop direct connection between the two nodes, meaning that the information between them does not need to be converted and forwarded through a third party.

[0145] The core network 40 can communicate with at least one access node, which may include access node 20; access node 20 can be connected to at least one computing unit, which includes computing unit 30. Access node 20 can also be connected to at least one terminal device, which includes terminal device 10. That is, at least one terminal device can be connected to a computing unit through one access node, or can be connected to multiple computing units through one access node.

[0146] Management module 50 can be a management module for computing services. Management module 50 can be an independent computing service management module in the operator's network, a functional module integrated into an existing network management system, or a functional module in a third-party computing service management system. Management module 50 may include a RAN management platform and a computing unit management platform. The computing unit management platform can be used to manage the computing services provided by computing unit 30, or to deploy function instances to computing unit 30 so that the computing resources provided by computing unit 30 can meet the SLA requirements of the corresponding computing services.

[0147] When computing function nodes are moved down the network, the network topology between computing units and access nodes typically adopts a star topology. This means that access nodes can connect to different computing units (see the description above for specific connection methods), and each access node can provide access services to multiple terminal devices. In this network topology, a key consideration is how to discover the computing function nodes that provide services for the computing tasks requested by terminal devices; in other words, how to rationally allocate computing function nodes for the computing tasks requested by terminal devices.

[0148] Figure 3 shows a schematic diagram of a network structure. As shown in Figure 3, RAN node #1 (i.e., an example of an access node) is connected to computing function nodes #1, #2, and #3, which can provide computing power services a, b, and c, respectively. RAN node #2 is connected to computing power nodes #4, #5, and #6, which can provide computing power services d, e, and f, respectively.

[0149] Taking the network structure shown in Figure 3 as an example, assuming that UE#1 (an example of a terminal device) is currently connected to RAN node #1, the discovery of computing power nodes (or computing power services) needs to be considered in the following two scenarios.

[0150] Scenario 1: UE#1 needs to call the computing power service e.

[0151] Scenario 2: UE#1 needs to call computing power service d. The computing power node connected to RAN node #1 that can provide computing power service d is experiencing one or more of the following situations: computing resources are scarce, the number of users served has reached the limit, the number of connections has reached the limit, the number of remaining cores has reached the limit, and resource availability is limited.

[0152] In view of this, this application provides a communication method and a communication device, which are beneficial to solving or improving the above problems.

[0153] Figure 4 shows a schematic flowchart of a communication method 400 provided in an embodiment of this application. Method 400 may include some or all of the following steps.

[0154] S410, Access node #1 (an example of the first access node) obtains (perceives) the computational information of the adjacent access nodes.

[0155] In this context, access node #1 can be the access node that the terminal device is currently accessing, or in other words, access node #1 is the access node that is currently providing services to the terminal device; or, access node #1 can be a node connected to a computing function node, such as a user plane network element.

[0156] For example, access nodes can be configured to be aware of the computation information of neighboring access nodes by default; alternatively, access nodes can obtain the computation information of neighboring access nodes based on local configuration or local policies; or, access nodes can obtain the computation information of neighboring access nodes based on instructions from core network elements (e.g., policy control function elements). This application does not restrict the triggering conditions for access nodes to obtain the computation information of neighboring access nodes.

[0157] In this application, "computing information" can also be replaced with "computing power information", "computing power service related information", etc., and the name of the information is not limited.

[0158] The computing information of the access node can indicate the computing services that the computing nodes connected to the access node can provide, or in other words, the computing services that the access node can provide.

[0159] For example, the calculation information includes at least one of the following:

[0160] Information about the compute nodes and the computing services they provide.

[0161] The information of the computing node may include at least one of the following:

[0162] The identifier of the computing node (such as at least one of the computing node's ID, name, and communication address (such as the IP address assigned to the computing node), the location information of the computing node, the regional information of the computing node, and the information on the computing services that the computing node can provide.

[0163] For example, the location information of a computing node can indicate the geographical location of the computing node. For instance, the geographical location can be an administrative region such as a province, city, county, town, or street. The location information can be an identifier of the geographical location, such as the code corresponding to the province, city, county, town, or street. Location information can also have other representations, without limitation.

[0164] The regional information of a computing node indicates the area where it can provide computing services. For example, the granularity of the region can be cell, tracking area (TA), geographic location area, or access node ID. This regional information can include the location area code (LAC), tracking area identifier (TAI), cell ID, geographic area identifier (GAI), network code (NC), country code (CC), city code, and county code of the service area provided by the computing node.

[0165] Information about the computing services that a computing node can provide can also be referred to as the computing node's capability information. For example, this capability information includes the type and name of the computing services that the computing node can provide.

[0166] The above-mentioned access node corresponding to (connecting to) the computing node can be understood as follows: the access node can communicate and connect with the computing node, or the access node includes the computing node (such as the computing node being a functional module in the access node used to provide computing services); the computing services provided by the computing node can also be referred to as the computing services supported by the computing node, and when the access node corresponds to (connects to) the computing node, it can also be referred to as the access node supporting the computing services provided by the computing node. The following omits the description of the same or similar situations.

[0167] For example, when access node #1 corresponds to computing node #1 and computing node #2, and computing node #1 supports computing services a and b, and computing node #2 supports computing services c and d, it can also be said that access node #1 supports computing services a to d.

[0168] Optionally, for an access node that corresponds to (connects to) at least one computing node, the computing services provided by each computing node can be the same or different. For example, access node #1 corresponds to computing node #1 and computing node #2. Computing node #1 can support computing services a and b, and computing node #2 can support computing services c and d, or computing node #2 can support computing service b.

[0169] The information provided by the computing services of the computing node includes at least one of the following:

[0170] The communication address of each computing service provided by the computing node, the identifier of each computing service, or the attribute (attribute or profile) information of each computing service.

[0171] The communication address of a computing service may include its entry point address or interface address, and / or port number. The identifier of a computing service may be its ID or name. The attribute information of a computing service, also known as its characteristics, may include its performance requirements. For example, this includes requirements for service quality and latency, such as QoS information and latency information. The latency information may include the total latency required from the time a terminal device sends a scheduling request for the computing service to the time it receives the execution result. In practice, the performance requirements may include SLA (Service Level Agreement) requirements. Furthermore, the attribute information of each computing service may also include the number of users or connections it supports, indicating how many terminal devices the computing service can simultaneously serve.

[0172] Taking the acquisition of computing information corresponding to access node #2 by access node #1 as an example, access node #2 is connected to computing node #2, and computing node #2 provides computing services 1 to 3. The computing information may include the following:

[0173] {<ID-1,name-1,URL-1,entrypoint-1 / interface-1,SLA-1> ,<ID-2,name-2,URL-2,entrypoint-2 / interface-2,SLA-2> ,<ID-3,name-3,URL-3,entrypoint-3 / interface-3,SLA-3>}

[0174] Wherein, ID-n represents the identifier of computing service n, name-n represents the name of computing service n, URL-n represents the calling path of computing service n, entrypoint-n represents the entry point address of computing service n, interface-n represents the interface address of computing service n, and SLA-n represents the SLA of computing service n, where n is 1, 2, or 3.

[0175] Optionally, the computation information includes information about the computation nodes. For example, access node #1 obtains computation information corresponding to access node #2, which connects computation node a and computation node b. Computation node a and computation node b each provide a set or a single computation service. This computation information can be represented in any of the following forms:

[0176] 1) {<compute node a - communication address, [compute service list] - a>, <compute node b - communication address, [compute service list] - b};

[0177] 2) {<compute node a-communication address, compute node a-ID, [compute service list]-a>, <compute node b-communication address, compute node b-ID, [compute service list]-b>}; or,

[0178] 3) {<Compute node a-communication address, compute node a-ID, compute node a-name, [compute service list]-a>, <Compute node b-communication address, compute node b-ID, compute node b-name, [compute service list]-b>}.

[0179] Wherein, the above-mentioned computing node m-ID, computing node m-name, and computing node m-communication address are the identifier, name, and communication address of computing node m, respectively, and m is either a or b.

[0180] For example, the above [computing service list] includes at least one of the following information that each computing node can provide: the identifier of the computing service, the communication address of the computing service, and the attribute information of the computing service. For example, [computing service list]-a includes at least one of the following: the identifier, communication address, SLA, and the number of supported users / connections of the computing services supported by computing node a.

[0181] It should be understood that the form and content of the above-mentioned computing information are merely illustrative examples. In actual implementation, the computing information may include more or less content. For example, the computing information may not include the identifier or name of the computing service, or it may not include SLA information. For another example, the computing information may also include the number of users or connections supported by each computing service.

[0182] Optionally, the method further includes: S420, access node #1 establishes a connection with an adjacent access node.

[0183] That is, after the access node # obtains the calculation information of the adjacent access nodes, it establishes connections with each of the adjacent access nodes respectively.

[0184] For example, access node #1 can send a connection establishment request to a neighboring access node. This connection establishment request message can be used to request the establishment of a connection between access node #1 and a neighboring access node (e.g., access node #2).

[0185] The connection can be at the service level or the node level.

[0186] For example, when the connection is a service-level connection, it can be used to carry messages for a specific computing service. For instance, the connection can be used to carry messages for computing service a supported by access node #2. The messages for computing service a can be specific to different UEs.

[0187] Optionally, access node #1 stores a mapping #1 between the computing services that the connection can support and the connection (an example of a first mapping), or in other words, access node #1 stores a mapping #1 between the identifier of the connection and the identifier of the computing service, where the computing service is the computing service that the connection can support. The mapping #1 may also include the computing services that the connection can support and / or the mapping between the connection and the access node.

[0188] For example, connection #1 between access node #1 and access node #2 is used to carry messages for computing service a. Access node #1 can store the correspondence between the identifier of connection #1 and the identifier of computing service a. Access node #1 can also store the correspondence between the identifier of connection #1 and / or the identifier of computing service a and access node #2.

[0189] When the connection is at the node level, it can carry messages for at least one computing service supported by the computing node. These messages for the at least one computing service can be specific to different UEs.

[0190] For example, if access node #2 is connected to computing node #1, and computing node #1 supports computing service a and computing service b, then this connection can be used to carry messages of the computing services supported by computing node #1, namely, messages of computing service a and computing service b.

[0191] Optionally, access node #1 may store a mapping #2 between at least one computing service and the connection (an example of a first mapping). The mapping #2 may also include the mapping between the at least one computing service and / or the connection and the access node.

[0192] For example, access node #2 connects to computing node #1, and computing node #1 supports computing service a and computing service b. Connection #2 between access node #1 and access node #2 is used to carry the computing services supported by computing node #1. Therefore, access node #1 can store the correspondence between the identifier of connection #2 and the identifiers of computing services a and b. Access node #1 can also store the correspondence between the identifier of connection #2 and / or the identifiers of computing services a and b and access node #2.

[0193] Optionally, when an adjacent access node corresponds to multiple computing nodes, the connection can be used to carry messages of computing services supported by at least one of the multiple computing nodes.

[0194] For example, if access node #2 connects to compute node #1 and compute node #2, and compute node #1 supports compute service a and compute service b, and compute node #2 supports compute service c, then this connection can be used to carry messages of the compute services supported by compute node #1, i.e., messages of compute service a and compute service b; or, this connection can be used to carry messages of the compute services supported by compute node #2, i.e., messages of compute service c; or, this connection can be used to carry messages of the compute services supported by compute node #1 and compute node #2, i.e., messages from compute service a to compute service c.

[0195] Optionally, when the connection is used to carry messages for computing services supported by all computing nodes connected to an adjacent access node, the connection can be understood as an access node-level connection.

[0196] For example, if access node #2 is only connected to compute node #1, and compute node #1 supports compute service a and compute service b, then this connection can be used to carry messages of the compute services supported by access node #2, namely, messages of compute service a and compute service b.

[0197] For example, a direct or indirect connection is established between access node #1 and its neighboring access nodes.

[0198] Taking adjacent access nodes, including access node #2, as an example, access node #1 can establish a direct connection with access node #2 through the interface between access node #1 and access node #2; alternatively, access node #1 can establish an indirect connection with access node #2 through a core network element (such as a UPF located in the edge area); or, access node #1 can establish an indirect connection with access node #2 through an intermediate node (such as access node #3). This application does not limit the method by which access node #1 establishes a connection with adjacent access nodes.

[0199] Furthermore, this application does not restrict the triggering conditions for connection establishment. For example, the connection establishment request sent by access node #1 to a neighboring access node can be triggered when the access node senses the computational information of the neighboring access node. Optionally, the connection establishment is triggered in the following process:

[0200] 1) During the process of the terminal device initiating a computing power connection establishment request (see the description in S460 for details).

[0201] 2) During the discovery process of computing services, such as during a DNS query request.

[0202] For example, after the terminal device initiates a computing power connection establishment request, the terminal device queries the IP address corresponding to the computing service through the Domain Name System (DNS) server. That is, the terminal device can send a DNS Query request to the DNS server through access node #1. After receiving the DNS Query request, access node #1 triggers the sending of a connection establishment request to the adjacent access node based on the queried computing service and the information of the adjacent access nodes corresponding to the computing service.

[0203] The aforementioned connections can be distinguished by connection identifiers. For example, a connection can be implemented using tunnels, in which case the connection identifier can be the identifier of the tunnel of access node #1 and / or adjacent access nodes. For instance, if the connection uses a General Packet Radio Service (GPRS) tunneling protocol user plane (GTPU) tunnel, the connection identifier can be the tunnel information of the GTPU tunnel; as another example, if the connection uses a Generic Routing Encapsulation (GRE) tunnel, the connection identifier can be a key identifier. This application does not limit the specific method of establishing the connection or the specific identifier of the connection.

[0204] S430, the terminal device sends the first information to access node #1. Correspondingly, access node #1 receives the first information.

[0205] The first information can be used to request the establishment of a connection with computing node 1. Computing node 1 can provide computing services associated with computing task 1 (an example of the first computing task), such as computing service 1, an example of the first computing service. The first information includes the identifier of computing service 1. Computing task 1 is a computing task initiated by a terminal device. The computing service associated with computing task 1 can be understood as computing task 1 being provided by computing service 1.

[0206] In one example, the first message is a scheduling request message for computing task 1. This scheduling request message can be used to request that computing services be scheduled for computing task 1 and / or computing resources be allocated. The scheduling request may carry an identifier of computing service 1. For example, the scheduling request message carries an identifier of computing task 1, which may include the identifier of computing service 1 and / or its communication address.

[0207] For example, when a user triggers computing task 1 (such as triggering an application (APP)), the terminal device sends a scheduling request message for computing task 1 to access node #1.

[0208] For example, the scheduling request message can be air interface control signaling. This air interface control signaling can be access stratum (AS) signaling, such as radio resource control (RRC) signaling, or it can be non-access stratum (NAS) signaling. NAS signaling can refer to the terminal device sending a scheduling request message to a control plane function element (such as XCF), which then establishes a connection between the terminal device and the computing node.

[0209] In this example, access node #1 can be a node that provides access services to terminal devices, such as a RAN node.

[0210] In another example, the first information is the data of computing task 1, such as the first data packet of computing task 1. This data packet may carry the identifier of computing service 1, such as the communication address of computing service 1 (e.g., the IP address of computing service #1, the identifier of the computing service, the port number, and the protocol type, etc.).

[0211] In this example, access node #1 can be a node that provides access services to the terminal device, such as a RAN node. Access node #1 can also be a node connected to a computing service, such as a user plane network element. In this case, access node #1 can receive the first information through the node that provides access services to the terminal device.

[0212] S440, Access node #1 determines access node #2 (an example of a second access node) based on the calculation information of the adjacent access nodes and the identifier of the first calculation service.

[0213] Among them, access node #2 is the access node that supports computing service 1, and access node #2 is one of the adjacent access nodes.

[0214] In other words, by executing S410, access node #1 obtains the computing services that each adjacent access node can provide. By executing S420, access node #1 obtains the identifier of computing service 1 associated with the computing task requested by the terminal device. Thus, access node #1 can determine which of the adjacent access nodes can provide computing service 1. That is, the computing services provided by each adjacent access node include computing service 1, and the access node corresponding to computing service 1 is the second access node.

[0215] In one possible implementation, if access node #1 stores a first correspondence, the second access node is determined based on the first correspondence and the identifier of computing service 1. Optionally, access node #1 determines the connection established with the second access node. That is, it determines the connection corresponding to the identifier of computing service 1 from the first correspondence, and determines the access node corresponding to the connection. The first correspondence refers to correspondence #1 and correspondence #2 in S420.

[0216] In another possible implementation, if access node #1 does not store the first correspondence, then access node #2 is determined based on the computation information of adjacent access nodes and the identifier of computation service 1. That is, the supported computation services include the adjacent access nodes of computation service 1 as access node #2. Optionally, if the connection between access node #1 and access node #2 is not established, access node #1 triggers the establishment of a first connection with access node #2 based on the first information. This first connection can be used to carry the data of computation task 1.

[0217] Optionally, in the above implementation, if the supported computing service includes multiple adjacent access nodes for computing service 1, the access node can also determine access node #2 from among these multiple adjacent access nodes. For example, access node #2 can be determined based on the load conditions and SLA requirement information of these multiple adjacent access nodes.

[0218] S450, Access node #1 sends data for computing task 1 to access node #2.

[0219] After determining access node #2, access node #1 sends the data for computation task 1 to access node #2 through the connection between them. For example, if there is no connection between access node #1 and access node #2, access node #1 establishes a connection with access node #2 and sends the data for computation task 1 to access node #2 through this connection; if there is a connection between access node #1 and access node #2, access node #1 directly sends the data for computation task 1 to access node #2 through this connection. Alternatively, access node #1 sends the data for the computation task to access node #2 through interface #1, which is the interface between access node #1 and access node #2.

[0220] For example, if the connection between access node #1 and access node #2 is a service-level connection, then the data sent by access node #1 may carry a connection identifier. Optionally, the sent data may carry a terminal device identifier.

[0221] If the connection between access node #1 and access node #2 is a node-level connection, then the data sent by access node #1 may carry a connection identifier. Optionally, the sent data may carry at least one of the identifier of the terminal device and the identifier of the computing service.

[0222] Furthermore, the method also includes:

[0223] S460, Access node #2 sends the data of computing task 1 to computing node #1.

[0224] Among them, computing node 1 is the computing node that can provide computing service 1 among the computing nodes supported by access node #2.

[0225] For example, if access node #2 is directly connected to computing node 1 or indirectly connected. Indirect connection can mean that access node #2 and computing node 1 are connected through another network device (denoted as network device #1), or access node #2 is directly connected to network device #1, and access node #2 is connected to computing node 1 through network device #1.

[0226] As an example, network device #1 is a user plane network element, such as a UPF. That is, access node #2 sends the data for computing task 1 to the user plane network element, which then sends it to computing node 1. The user plane network element and access node #2 can be configured independently, or they can be shared.

[0227] As another example, network device #1 is a gateway. That is, access node #2 sends the data of computing task 1 to the gateway, and then the gateway sends the data to computing node 1 according to the destination address and routing information.

[0228] Figure 5 shows a schematic flowchart of a communication method 500 provided in an embodiment of this application. Method 500 may include the following steps.

[0229] S510, Access Node #1 (an example of the first access node) obtains the calculation information of the adjacent access nodes.

[0230] In this context, access node #1 can be the access node that the UE is currently accessing, or in other words, access node #1 is the access node that is currently providing services to the UE.

[0231] The computing information of an access node can indicate the computing services that the computing nodes connected to the access node can provide, or in other words, the computing services that the access node can provide. The specific content of this computing information, and the method of obtaining it, can be found in the description in S410.

[0232] Understandably, this step is optional.

[0233] S520, the terminal device sends the first information to access node #1. Correspondingly, access node #1 receives the first information.

[0234] The first information can be used to request the establishment of a connection with computing node 1. Computing node 1 can provide computing services associated with computing task 1 (an example of the first computing task), such as computing service 1, an example of the first computing service. The first information includes the identifier of computing service 1. Computing task 1 is a computing task initiated by a terminal device. The computing service associated with computing task 1 can be understood as computing task 1 being provided by computing service 1.

[0235] In one example, the first message is a scheduling request message for computing task 1. This scheduling request message can be used to request that computing services be scheduled for computing task 1 and / or computing resources be allocated. The scheduling request may carry an identifier for computing service 1.

[0236] For example, the scheduling request message can be air interface control signaling. This air interface control signaling can be AS signaling or NAS signaling.

[0237] In another example, the first information is the data for computing task 1, such as the first data packet of computing task 1, which may carry the identifier of computing service 1.

[0238] Optionally, when the first information is NAS signaling, the method further includes: the access node #1 sending the first information to the control plane function network element.

[0239] For details on this step, please refer to S430.

[0240] S530, Access node #1 determines access node #2 (an example of a second access node) based on the computing information of adjacent access nodes and the terminal device's access to the first computing service.

[0241] Access node #1 can determine the terminal device's access to the first computing service based on the identifier of computing service 1 contained in the AS signaling in S520, or based on the destination address of the data packet of computing task 1 or the identifier of computing service 1 carried in the data packet.

[0242] It is understandable that if the first information in S520 is NAS signaling, then S530 can be replaced by the control plane function network element determining access node #2 based on the terminal device's access to the first computing service and the computing information of adjacent access nodes.

[0243] Among them, access node #2 is the access node that supports computing service 1, and access node #2 is one of the adjacent access nodes.

[0244] In other words, by executing S510, access node #1 obtains the computing services that each adjacent access node can provide, and by executing S520, access node #1 obtains the identifier of computing service 1 associated with the computing task requested by the terminal device. Thus, access node #1 can determine which of the adjacent access nodes can provide computing service 1.

[0245] For details on this step, please refer to S440.

[0246] S540, Access node #1 redirects or switches the terminal device to access node #2.

[0247] That is, the terminal device switches from access node #1 to access node #2, or in other words, the terminal device connects to access node #2, and subsequently, access node #2 provides services to the terminal device.

[0248] For example, after determining that access node #2 can provide the requested computing service to the terminal device, access node #1 sends an instruction message to the terminal device, instructing the terminal device to switch to access node #2.

[0249] The specific implementation of the terminal device switching from access node #1 to access node #2 can refer to existing related solutions and is not limited. For example, the terminal device can switch from access node #1 to access node #2 (N2 switching) based on the N2 interface (an example of the interface between access node #1 and access node #2).

[0250] It is understandable that if the first information in S520 is NAS signaling, then S540 can be replaced with: the control plane function network element redirects or switches the terminal device to access node #2.

[0251] S550, the terminal device sends the first information to access node #2.

[0252] The first information can be used to request the establishment of a connection with computing node 1. Computing node 1 can provide computing services associated with computing task 1 (an example of the first computing task), such as computing service 1, an example of the first computing service. The first information includes the identifier of computing service 1. Computing task 1 is a computing task initiated by a terminal device.

[0253] In one example, the first message is a scheduling request message for computing task 1. This scheduling request message can be used to request that computing services be scheduled for computing task 1 and / or computing resources be allocated. The scheduling request may carry an identifier for computing service 1.

[0254] For example, the scheduling request message can be air interface control signaling. This air interface control signaling can be AS signaling or NAS signaling.

[0255] In another example, the first information is the data for computing task 1, such as the first data packet of computing task 1, which may carry the identifier of computing service 1.

[0256] Optionally, when the first information is NAS signaling, the method further includes: the access node #2 sending the first information to the policy control network element.

[0257] For more details, please refer to the description in S430.

[0258] That is, after redirecting the terminal device to access node #2, the terminal device initiates a scheduling request for computing task 1 to access node #2, or sends the data for computing task 1.

[0259] Optionally, access node #2 identifies the computing power service requested by the terminal device and allocates air interface resources to the terminal device based on computing power information (such as SLA and / or QoS description) so that the terminal device can transmit data from computing service 1.

[0260] In S560, the terminal device transmits data to the computing node 1 through access node #2.

[0261] Among them, computing node 1 is the computing node that can provide computing service 1 among the computing nodes supported by access node #2.

[0262] For example, the terminal device can send data of computing task 1 to computing node 1 through access node #2, and computing node 1 can send data of computing service 1 to the terminal device through access node #2.

[0263] Access node #2 is directly or indirectly connected to compute node 1. An indirect connection can mean that access node #2 and compute node 1 are connected through another network device (denoted as network device #1), or that access node #2 is directly connected to network device #1, and access node #2 is connected to compute node 1 through network device #1.

[0264] As an example, network device #1 is a user plane network element, such as a UPF. That is, access node #2 sends the data of computing task 1 to the user plane network element, and then the user plane network element sends it to computing node 1. For details, please refer to the description in S460.

[0265] As another example, network device #1 is a gateway. That is, access node #2 sends the data of computing task 1 to the gateway, and then the gateway sends the data to computing node 1 according to the destination address and routing information. For details, please refer to the description in S460.

[0266] Figure 6 shows a schematic flowchart of a communication method 600 provided in an embodiment of this application. Method 600 may include the following steps.

[0267] S610, the terminal device obtains the first information.

[0268] The first information may include computing information for each of the at least one access node. This computing information indicates the computing services supported by each access node. The at least one access node may include the access node currently accessed by the terminal device, and / or the adjacent access nodes of the currently accessed access node.

[0269] It is understandable that the computing services supported by an access node can be represented by an index indicator. For example, an index indicator of 1 indicates that the computing service supported by the access node is x. In this case, the terminal device can also configure the mapping relationship between computing services and index indicators. This mapping relationship can be obtained from the network side, for example, in the registration process initiated by the terminal device, the control plane function network element configures this mapping relationship on the terminal device.

[0270] In one example, the terminal device obtains the computation information of each access node. For instance, during the network initialization phase of the terminal device, the terminal device receives a broadcast message from each of the at least one access node, which may include the access node's computation information in addition to necessary system information.

[0271] In another example, the terminal device obtains this first information from access node #1 (an example of the first access node). That is, the terminal device obtains this first information from the access node it is currently connected to.

[0272] The terminal device may obtain this first information during the connection establishment process with access node #1, the registration process, or other processes of interaction with access node #1, without limitation. For example, during the RRC connection establishment process of the terminal device, the terminal device receives the first information from access node #1. If the random access procedure is successful, an RRC connection will be established between the terminal device and access node #1, and the terminal device will send an RRC connection establishment request to access node #1. After receiving the request, access node #1 will authenticate the terminal device and finally send an RRC connection establishment completion message to the terminal device. The RRC connection establishment completion message may carry the first information.

[0273] In this example, the first information includes the calculation information of access node #1 and / or the calculation information of the neighboring access nodes of access node #1. That is, the at least one access node may include access node #1 and / or the neighboring access node. Optionally, before sending the first information to the terminal device, access node #1 may also obtain the calculation information of the neighboring access nodes, as described in S410.

[0274] In another example, the network side configures this first information for the terminal device.

[0275] For example, in the registration process or connection establishment process of a terminal device, the network side sends the first information to the terminal device. For example, during the registration process of the terminal device, the terminal device can obtain the first information from the policy control network element through access node #1. The first information can be carried by NAS signaling; or, the application server side sends the first information to the terminal device through the application layer; or, the first information can also be configured in the terminal device.

[0276] The computing information of the aforementioned access node can indicate the computing services that the computing nodes connected to the access node can provide, or in other words, it indicates the computing services that the access node can provide. The specific content of this computing information can be found in the description in S410.

[0277] S620, the terminal device determines access node #2 (an example of the access node to be accessed) based on the identifier of the first information and computing service 1 (an example of the first computing service).

[0278] Access node #2 is one of the at least one access node, and access node #2 supports computing service 1. Computing service 1 is the computing service associated with the computing task requested by the terminal device.

[0279] In other words, the terminal device obtains the computing services that each adjacent access node can provide, as well as the identifier of computing service 1 associated with the computing task that the terminal device knows to request, so that the terminal device can determine the access node among the adjacent access nodes that can provide computing service 1.

[0280] Optionally, in step S630, the terminal device sends a second message to access node #2. Correspondingly, access node #2 receives the second message.

[0281] The second information can be used to request the establishment of a connection with computing node 1. Computing node 1 can provide computing services associated with computing task 1 (an example of the first computing task), such as computing service 1, an example of the first computing service. The first information includes the identifier of computing service 1. Computing task 1 is a computing task initiated by a terminal device.

[0282] In one example, the second piece of information is a scheduling request message for computing task 1. This scheduling request message can be used to request that computing services be scheduled for computing task 1 and / or computing resources be allocated. The scheduling request may carry an identifier for computing service 1.

[0283] For example, the scheduling request message can be air interface control signaling. This air interface control signaling can be AS signaling or NAS signaling.

[0284] In another example, the second information is the data for computing task 1, such as the first data packet of computing task 1, which may carry the identifier of computing service 1.

[0285] For details of the second information, please refer to the description of the first information in S430.

[0286] That is, after redirecting the terminal device to access node #2, the terminal device initiates a scheduling request for computing task 1 to access node #2, or sends the data for computing task 1.

[0287] Optionally, access node #2 identifies the computing power service requested by the terminal device and allocates air interface transmission resources to the terminal device based on computing power information (such as SLA and / or QoS description) so that the terminal device can transmit data from computing service 1.

[0288] S640, the terminal device transmits data with the computing node 1 through access node #2.

[0289] Among them, computing node 1 is the computing node that can provide computing service 1 among the computing nodes supported by access node #2.

[0290] For example, the terminal device can send data of computing task 1 to computing node 1 through access node #2, and computing node 1 can send data of computing service 1 to the terminal device through access node #2.

[0291] Access node #2 is directly or indirectly connected to computing node 1. An indirect connection can mean that access node #2 and computing node 1 are connected through another network device (denoted as network device #1), or that access node #2 is directly connected to network device #1, and access node #2 is connected to computing node 1 through network device #1.

[0292] As an example, network device #1 is a user plane network element, such as a UPF. That is, access node #2 sends the data of computing task 1 to the user plane network element, and then the user plane network element sends it to computing node 1. For details, please refer to the description in S460.

[0293] As another example, network device #1 is a gateway. That is, access node #2 sends the data of computing task 1 to the gateway, and then the gateway sends the data to computing node 1 according to the destination address and routing information. For details, please refer to the description in S460.
