Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a service access method, apparatus, device, storage medium, and computer program product. Background Technology

[0002] In related technologies, network management and orchestration systems typically utilize the computing power of the radio access network (RAN) through interface procedures such as the Management and Orchestration (MANO) system defined by the European Telecommunications Standards Institute (ETSI) and the O2 interface procedure of the Open Radio Access Network (O-RAN) system. When RAN computing power is shared and open, orchestration systems such as MANO and O-RAN can be used to deploy computing tasks. However, considering the fluctuation of base station computing power and the fact that latency-sensitive service terminals are often in motion, using the MANO resource orchestration method will lead to increased backhaul latency between computing tasks during terminal cross-site movement, resulting in poor real-time performance.

[0136] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0137] To make the embodiments of this application clearer, the relevant technical knowledge involved in the embodiments of this application will be introduced as follows:

[0138] With the gradual convergence of Communication Technology (CT) and Internet Technology (IT), 5G is also evolving towards cloudification. Traditional dedicated hardware is evolving towards general-purpose servers, and traditional dedicated wireless base station hardware resources will gradually evolve towards wireless-side cloud platforms by adding accelerator cards. This allows for the agile deployment of local field-level or edge service applications while supporting wireless data plane and control plane functions. Based on the wireless-side cloud infrastructure, the wireless side also possesses the ability to support diverse computing resources and unified computing power orchestration and scheduling. The challenge now is how to fully utilize the remaining computing resources of base stations to maximize their value. Considering the distributed nature of base stations, it is necessary to uniformly manage and control these dispersed computing resources to achieve a synergistic effect while meeting the requirements of latency-sensitive services such as Extended Reality (XR) and Vehicle-to-Everything (V2X) communication.

[0139] With the continuous development of new businesses such as intelligent services, XR, metaverse-like immersive services, connected vehicles, and the Internet of Things (IoT), intelligent terminals are not only becoming more diversified in product form (such as wearable devices, smart homes, IoT devices, and in-vehicle devices), but also benefiting from the continuous maturation of semiconductor technology and the introduction of artificial intelligence (AI) chips, their computing capabilities have also developed rapidly. Considering the limitations of terminal-side computing capabilities due to factors such as computing power, battery capacity, and heat dissipation, as well as the sensitivity of immersive services to experimentation, it is necessary to research technical solutions that provide computing services to terminals from the base station perspective, assisting terminals in completing computing tasks in real time.

[0140] In related technologies, the use of wireless access network computing power is typically achieved by network management and orchestration systems through interface procedures such as the MANO system defined by ETSI and the O2 interface procedures of the O-RAN system, which instantiate computing tasks on wireless computing power. Typically, this resource orchestration of network infrastructure is static or semi-static. Static or semi-static means that, for example, after the MANO system deploys virtualized network functions based on Network Service Descriptors (NSDs) or Virtual Network Function Descriptors (VNFDs), it does not require dynamic near-real-time / real-time adjustments to infrastructure resources. Lifecycle management of VNFs / CNFs is usually only performed after certain preset events occur (e.g., a Virtualized Network Function (VNF) / Cloud-native Network Function (CNF) exceeds a set threshold, etc.).

[0141] When base station computing power sharing is opened up, computing tasks are deployed through orchestration systems such as MANO and O-RAN. Considering the volatility of base station computing and the mobile status of terminals providing latency-sensitive services such as V2X, UAV, and XR, the MANO system cannot perceive the communication status. This can lead to increased backhaul latency between terminals and computing tasks due to terminal movement across base stations, impacting the end-to-end service experience. For scenarios with open and shared wireless computing power, the MANO resource orchestration method is ill-suited to ensuring service experience during the movement of latency-sensitive services. Furthermore, while the network management system can interact with the MANO system, it cannot perceive terminal service quality status information in real time; for example, PM reports typically take 15 minutes, resulting in poor real-time performance.

[0142] In the technical fields related to 6G (6th Generation Mobile Communication Technology) networks, there is a vision to add network functions that integrate communication and computing at the core network or service layer, achieving dual-dimensional resource utilization of communication and computing. However, the distributed computing power of radio access network base stations, frequent terminal mobility, and strong fluctuations in radio computing power present the following problems for optimizing the use of radio computing power in the core network: First, it increases the frequency of information interaction between the base station and the core network; second, with the core network maintaining massive radio computing power, increasing the burden on the core network, real-time performance cannot be guaranteed. For example, in a handover process involving computing dimensions, the base station considers not only time-frequency resources but also computing resources (whether computing tasks need to be migrated, etc.) when making handover decisions. If the handover process increases interaction with the core network, backhaul latency, core network processing, and signaling interaction overhead will increase handover latency, and the Xn interface will lose its advantage of fast handover.

[0143] Based on the above, this application proposes a service access method, apparatus, device, storage medium, and computer program product, which can deploy decision computing task instances through a first network unit and allocate access addresses to the computing task instances in real time.

[0144] In this embodiment of the application, the first network unit in the wireless access network can receive computing tasks from the core network and complete the deployment of computing tasks on the wireless computing power. At the same time, the first network unit can schedule computing tasks in real time or near real time, complete the access of computing tasks according to the access address, ensure the end-to-end experience of services, and enhance real-time performance.

[0145] The following description, in conjunction with the accompanying drawings, details a service access method, apparatus, device, storage medium, and computer program product provided in this application through specific embodiments and application scenarios.

[0146] See Figure 1 , Figure 1 This is a flowchart of a service access method applied to a first network unit according to an embodiment of this application. The method specifically includes the following steps:

[0147] S101. Receive a first request sent by a second network unit, wherein the second network unit is a network unit in the core network.

[0148] It should be noted that, as Figure 2 As shown in the embodiments of this application, the first network unit and the second network unit can be set in the wireless network logical architecture. The second network unit is a network unit in the core network. The second network unit can be a newly added network unit with computing functions in the core network, or it can be an existing network unit in the core network. The first network unit introduces computing functions on the basis of its original functions. Because the first network unit introduces computing functions, the core network can publish computing tasks to the wireless access network for computing task deployment.

[0149] Therefore, the first network unit, as a network unit in the access network, can receive computing tasks from the core network and deploy these tasks to base station computing power, terminal computing power, etc. The second network unit can possess a RAN enhancement function within the Radio Access Network (RAN).

[0150] In the specific implementation of this application, the core network notifies the first network unit of the computing task deployment requirements through the interface between the first network unit and the second network unit, that is, the second network unit can send a first request to the first network unit.

[0151] It is worth noting that in this application embodiment, the first network unit is an access network device, and the second network unit is a core network device. The access network device can also be referred to as a radio access network device, radio access network (RAN), radio access network function, or radio access network unit. The access network device may include a next-generation base station (gNB), a wireless local area network (WLAN) access point, or a WiFi node, etc. The base station may be referred to as a node B, evolved Node B (eNB), access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), home B node, home evolved B node, transmission reception point (TRP), or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0152] Core network equipment may include, but is not limited to, at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support. Function (BSF), Application Function (AF), etc.

[0153] It should be noted that the embodiments in this application only use the core network equipment in the NR system as an example for introduction, and do not limit the specific type of core network equipment.

[0154] S102. Based on the first request, determine to deploy a computing task instance in the first network unit, the third network unit, or the terminal, wherein the third network unit is a network unit in the access network.

[0155] It should be understood that, such as Figure 3As shown, after receiving the first request, the first network unit can decide to deploy the computing task. The first network unit can deploy the computing task directly within itself, or it can deploy it to a third network unit in the access network, or it can deploy it to the terminal. It is worth noting that the third network unit is a network unit within the access network, and it can be a computing device on the base station side.

[0156] In some embodiments, the second network unit can send a first request carrying a computing task to the first network unit through the interface between the first network unit and the second network unit. The first network unit then decides on the deployment of the computing task and deploys it within the first network unit.

[0157] In some embodiments, if the first network unit decides that the computation task can be deployed on the third network unit through the first request, then instructs the third network unit to instantiate the computation task instance. In other embodiments, if the first network unit decides that the computation task can be deployed on the terminal, then the first network unit instructs the third network unit to deploy the computation task instance to the terminal, or the third network unit autonomously decides to deploy the computation task instance to the terminal.

[0158] S103. If the first request carries the first access address, instruct the access address corresponding to the computing task instance to be the first access address; or, if the first request does not carry the first access address, perform the first operation.

[0159] The first operation includes assigning a second access address to the computing task instance, or instructing the third network unit to assign a third access address to the computing task instance.

[0160] In some embodiments of this application, the access address allocated to the computing task may be carried in a first request, and the first network unit may directly use the first access address carried in the first request for the computing task instance. When the computing task is deployed on a third network unit, the first access address may be sent from the first network unit to the third network unit, and the third network unit may use the first access address specified by the first network unit. When the computing task is deployed on a terminal, the first access address may be sent from the first network unit to the third network unit, and then from the third network unit to the terminal, so that the terminal may use the first access address specified by the first network unit.

[0161] It is understood that the first access address in this application embodiment can be modified by session signaling and passed from the second network unit to the first network unit. In the 3rd Generation Partnership Project (3GPP), signaling interactions between the second and third network units are involved. For example, when the second network unit is the AMF in the core network and the third network unit acts as a base station, the following situations exist:

[0162] Session Resource Setup Request Transfer (PDU); this element is transparent to the AMF.

[0163] As can be understood, as shown in Table 1, Table 1 contains the content of the interactive signaling between the second network unit and the third network unit, specifically as follows:

[0164] Table 1

[0165]

[0166] Therefore, the following settings can be configured in the Uplink Transport Layer Information:

[0167] This cell provides transport layer information for the NG user plane, and this transport layer information is associated with a PDU session that matches an NG-RAN node–UPF pair. In this release, the cell indicates an IP address and a GTP Tunnel EndpointIdentifier.

[0168] As can be seen, in the embodiments of this application, a first access address for the computing task can be added to the signaling sent by the second network unit to the first network unit. The first access address can be used in the form of an IP address or in a service manner.

[0169] As shown in Table 2, Table 2 represents the content of the signaling sent by the second network unit to the first network unit, specifically as follows:

[0170] Table 2

[0171]

[0172] In some embodiments of this application, the access address allocated to the computing task can be directly allocated by either the first network unit or the third network unit. Specifically, the first network unit can allocate an access address to the computing task instance while deploying the computing task itself. When the computing task is deployed on the third network unit, the third network unit can allocate the access address, notify the first network unit of the access address, and finally, the first network unit notifies the second network unit of the access address of the computing task. When the computing task is deployed on a terminal, the first network unit can allocate an access address to the computing task instance and notify the second network unit of the access address.

[0173] In this way, the first network unit in the wireless access network can receive computing tasks from the core network and complete the deployment of computing tasks on the wireless computing power. At the same time, the first network unit can schedule computing tasks in real time or near real time, complete the access of computing tasks according to the access address, ensure the end-to-end experience of services, and enhance real-time performance.

[0174] Optionally, performing the first operation when the first request does not carry the first access address includes any one of the following:

[0175] When the computing task instance is deployed by the first network unit or the terminal, the second access address is allocated to the computing task instance;

[0176] In the case where the computing task instance is deployed by the third network unit, the third network unit is instructed to allocate the third access address to the computing task instance.

[0177] In some embodiments of this application, for cases where the first request does not carry a first access address, i.e., the core network has not allocated an access address for the computing task instance, the first network unit can decide on the deployment of the computing task, deploying the computing task to the first network unit or a terminal. In this case, the first network unit directly allocates its designated second access address. Alternatively, the first network unit can instruct a third network unit to deploy the computing task instance, or the third network unit can independently decide on the deployment of the computing task instance. In this case, the third access address of the computing task instance can be allocated and determined by the third network unit.

[0178] In this way, the first network unit in this embodiment can independently decide on the deployment of computing tasks based on task performance requirements such as communication needs and computing task requirements, thereby improving the flexibility of the computing task deployment process and service access process, and enabling the use of dynamically changing network environments. By allowing different network units to deploy computing tasks, network load can be better balanced, resource waste can be avoided, and optimal allocation of computing resources can be achieved.

[0179] Optionally, if the first request does not carry the first access address, the first request includes a first communication requirement and a first computing requirement, wherein the first computing requirement includes any one of a first indication information, a second indication information, and the first access address;

[0180] Wherein, the first indication information is used to instruct the first network unit to allocate the second access address to the computing task instance, and the second indication information is used to instruct the third network unit to allocate the third access address to the computing task instance.

[0181] In a specific embodiment of this application, the first network unit can decide on the deployment of computing tasks based on the first communication requirement and the first computing requirement in the first request. The first communication request can be described in a way that relates to a Service Level Agreement (SLA) or a way that maps to Quality of Service (QoS) requirements. The first computing requirement can be described in a way that describes computing resource requirements, or it can be described in terms such as Floating Point Operations Per Second (FLOPS) / TeraOperations Per Second (TOPS).

[0182] The first computing requirement can include any one of the following: first indication information, second indication information, and a first access address. The first computing requirement can indicate the allocation method of the access address for the computing task; for example, it can indicate that the access address is allocated by the first network unit. The first network unit can independently allocate a second access address. The allocated second access address is unique and unique within the RAN enhancement function to avoid address conflicts. The allocated second access address can be defined as a service, using service mapping for access addresses. The mapped address is unique within the first network unit, also avoiding address conflicts. The first computing requirement can include second indication information, which can be sent by the first network unit to the third network unit to indicate that the third network unit can independently allocate a third access address. The third access address is unique and can be displayed as an address or exist as a service.

[0183] In addition, the first computing requirement may also include a first access address. The first access address is an access address directly assigned by the second network unit or other network units in the core network. It can be displayed as an address or exist as a service. The first access address is unique to avoid address conflicts when instantiating computing tasks.

[0184] Optionally, the second access address is one of the first access address sets pre-configured in the first network unit, and the third access address is one of the second access address sets pre-configured in the third network unit.

[0185] In some alternative embodiments, the second access address assigned by the first network unit can be selected autonomously by the first network unit. The first network unit can select an access address from a pre-configured set of first access addresses as the first access address. Similarly, the third network unit can also select an access address from a pre-configured set of second access addresses as the third access address.

[0186] It is worth mentioning that the access addresses in the first and second access address sets are all unique addresses and do not conflict with each other, so as to optimize the allocation of computing resources and provide users with a better service experience.

[0187] Optionally, the first request includes a first address update pool or a second address update pool, wherein the first address update pool is used to update the access addresses in the first access address set, and the second address update pool is used to update the access addresses in the second access address set.

[0188] In other embodiments, due to the continuous dynamic changes in the network, the access addresses of computing task instances can also be updated in a timely manner. Therefore, the access addresses in the first access address set can be updated according to the first address update pool in the first request, or the access addresses in the second access address set can be updated in a timely manner according to the second address update pool in the first request. This improves the adaptability of each computing task instance and its access address in the embodiments of this application, and enhances the flexibility of service access.

[0189] Optionally, determining to deploy a computing task instance in the third network unit based on the first request includes: sending a first decision instruction to the third network unit based on the first request, wherein the first decision instruction is used to instruct the third network unit to deploy the computing task instance.

[0190] In some alternative embodiments, during the deployment of computing tasks and access, such as Figure 4 As shown, it includes the following steps:

[0191] S201, The second network unit sends a first request to the first network unit. The first request includes a first communication requirement and a first computing requirement. The first request does not carry a first access address.

[0192] In the above steps, by parsing the first communication requirement and the first computing requirement, it can be determined how to allocate computing resources. The computing task can be deployed in the third network unit and a corresponding access address can be assigned to it.

[0193] S302. Based on the first request, the first network unit determines that the third network unit will deploy the computing task instance and allocates a fifth access address to the third network unit.

[0194] S303, The first network unit sends a first decision instruction to the third network unit. The first decision instruction carries a fifth access address and is used to instruct the third network unit to deploy computing tasks.

[0195] S304, The third network unit sends a first response message to the first network unit;

[0196] The first response information is used to inform the first network unit that the third network unit has completed the deployment of the computing task.

[0197] S305, The first network unit sends a second response message to the second network unit;

[0198] The second response information is used to inform the second network unit that the computing task has been deployed on the third network unit.

[0199] S306. The terminal sends a session establishment request (PDU Session EstablishRequest) to the second network unit;

[0200] In this step, the terminal sends a PDU SessionEstablish Request to the second network element in the core network to request the establishment of a data session between the terminal and the core network. This enables the terminal to send and receive data. Simultaneously, the terminal can also request the core network to allocate necessary network resources to support data transmission. Furthermore, the PDU SessionEstablish Request can include parameters used to configure network services, such as QoS (Quality of Service) requirements and IP address allocation, to help the core network understand the terminal's connection status and ensure that the network can effectively manage and maintain the connection with the terminal.

[0201] S307, The second network unit sends a session resource setup request (PDU Resource Setup Request) to the terminal;

[0202] Based on the PDU Session Establish Request sent by the terminal, the second network unit can allocate session resources for the terminal by sending a PDU Resource Setup Request to the terminal. The PDU Resource Setup Request carries first extended information, which may include the following: a list of network units (a list of base stations that can access the computation task), identification information of at least one third network unit (i.e., identification information of at least one base station), and a second or third access address corresponding to the computation task instance.

[0203] As shown in Table 3 below, first extended information can be added to the session signaling between the terminal and the first network unit. This includes a gNB list (i.e., a network unit list), a gNB identifier (identification information of at least one third network unit, which may include identification information of all base stations in the gNB list), and a computing task access address. In this way, the terminal can use the first extended information provided by the first network unit, along with the gNB list and gNB identifier, to switch between multiple different network units and base stations. Simultaneously, providing the computing task access address enables the terminal to quickly locate and access the required computing resources, reducing latency and improving task processing efficiency. Furthermore, the transmitted first extended information can reduce the amount of information that needs to be transmitted in subsequent interactions, improving signaling efficiency.

[0204] Specifically, between the terminal and the second network unit, such as between the terminal and the AMF in the core network, it includes:

[0205] PDU session establishment accept;

[0206] Signaling definition.

[0207] The PDU session establishment acceptance message is sent by the SMF to the UE in response to the PDU session establishment request message, indicating successful establishment of a PDU session.

[0208] Signaling type: PDU SESSION ESTABLISHMENT ACCEPT

[0209] Significance: Dual

[0210] Direction: Network connection to User Equipment (UE)

[0211] Specifically, Table 3 shows the message content received during PDU session establishment. The content shown in Table 3 is as follows:

[0212] Table 3

[0213]

[0214] S308. The terminal sends a session resource setup response (PDU Session Setup response) to the second network unit; wherein, the session resource setup response includes extended information including a list of network units, identification information of at least one base station, and the access address corresponding to the computing task instance, and the list of network units includes at least one base station;

[0215] S309. The second network unit sends a session establishment response (PDU Session EstablishAccept) to the terminal;

[0216] It is understandable that when the terminal and the second network unit interact through the aforementioned PDU Resource Setup Request, PDU Session Setup response, and PDU Session Establish Accept, they can carry the first extended information. The first extended information can be updated in real time by the terminal or the first network unit and quickly transmitted between the terminal and the second network unit to maintain the flexibility of service access, reduce latency, and improve real-time performance.

[0217] S310, the terminal completes the access to the computing task.

[0218] In the above embodiments, the second network unit can trigger the first network unit to deploy computing tasks through the first request. After the first network unit deploys the computing tasks to the third network unit, the terminal can establish a session with the second network unit and transmit extended information. As a result, the terminal can access computing tasks and improve the flexibility of terminal service access.

[0219] Optionally, determining to deploy a computing task instance on the terminal based on the first request includes any one of the following:

[0220] Based on the first request, a decision is made to deploy the computing task instance on the terminal;

[0221] Based on the first request, a second decision instruction is sent to the third network unit, the second decision instruction being used to instruct the third network unit to decide to deploy the computing task instance on the terminal.

[0222] In optional embodiments of this application, the computing task can be deployed in any one of the first network unit, the third network unit, and the terminal. The first network unit can directly determine that the terminal will deploy the computing task based on the communication and computing requirements in the first request, or the third network unit can then decide on the deployment of the computing task. For details, please refer to the relevant descriptions in the above embodiments; to avoid repetition, this application will not repeat them.

[0223] Optionally, the method further includes:

[0224] The system receives a second request sent by the third network unit. The second request is used to request a mobile handover. The second request carries a fourth access address, a first identification information of the fourth network unit, and a second identification information of the computing task. The fourth network unit is a network unit of the same type as the third network unit. The fourth access address is an access address assigned by the third network unit to the computing task instance.

[0225] Based on the first identification information, a third decision instruction is sent to the fourth network unit, the third decision instruction being used to instruct the fourth network unit to deploy the computing task instance;

[0226] The system receives a first response sent by the fourth network unit, the first response carrying third identification information and terminal identification of the fourth network unit deploying the computing task instance.

[0227] In some optional embodiments, since the terminal is in a mobile access scenario, to ensure end-to-end service experience, computing task migration is required when the terminal switches base stations. The first network unit allocates the access address for the computing task, and the terminal can undergo a mobile connection handover across the first network unit, switching from accessing the third network unit to accessing the fourth network unit. The third and fourth network units can be different base stations. If the third network unit does not deploy the computing task instance, it can be instantiated in the fourth network unit. Thus, because the network unit deploying the computing task migrates, the access address of the computing task also changes. At this time, the second network unit can promptly notify the terminal of the change in the computing task access address through subordinate messages or other signaling. This effectively reduces latency and ensures the continuity of terminal service access.

[0228] Therefore, this application provides a service access method, which specifically includes the following steps:

[0229] S401. The terminal sends a measurement report to the third network unit. The measurement report includes the second identification information of the terminal's computing task.

[0230] S402. Based on the measurement report, determine the fourth network unit corresponding to the terminal and allocate a fourth access address to the computing task;

[0231] It should be noted that when a terminal moves within a network, it needs to switch from one base station to another to maintain connectivity, especially when the mobile device enters a new coverage area. While the terminal is preparing for handover, the mobile device or the network can prepare for the upcoming base station handover. When the terminal switches access networks, it can send a measurement report to the original access network, which is then transmitted by the third network unit to the first network unit, providing the identification information of the target base station to be handed over. This identification information can be used to identify the base station the terminal will soon connect to (i.e., the fourth network unit) to ensure a correct handover operation.

[0232] S403. Send a second request to the first network unit, the second request carrying a fourth access address, first identification information and second identification information of the fourth network unit;

[0233] S404. Based on the first identification information, a third decision instruction is sent to the fourth network unit. The third decision instruction is used to instruct the fourth network unit to deploy computing task instances.

[0234] It should be noted that after the first network unit receives the second request sent by the third network unit, the first network unit can send a third decision instruction to the fourth network unit based on the first identifier information of the fourth network unit determined by the third network unit. After receiving the fourth decision instruction, the fourth network unit can deploy the computing task, that is, complete the transfer of the computing task deployment, transferring the computing task deployment from the third network unit to the fourth network unit to which the terminal will switch, thus ensuring the continuity of terminal service access.

[0235] Furthermore, the third network unit allocates an access address for the computing task, and the terminal performs a handover across base stations. If the fourth network unit does not deploy an instance of the computing task, the first network unit can instantiate the computing task in the fourth network unit. Due to the change in the access address of the computing task, the first network unit needs to promptly notify the second network unit, informing it that the access address of the terminal's computing task has changed to the fourth access address.

[0236] S405. The first network unit receives a first response sent by the fourth network unit, the first response carrying third identification information and terminal identification of the fourth network unit deploying the computing task instance;

[0237] Specifically, after completing the deployment of the computing task and the allocation of the access address, the fourth network unit sends a first response to the first network unit to notify the first network unit that the deployment of the computing task is complete. The first response may also carry the fourth access address allocated by the fourth network unit for the computing task, so that the first network unit can promptly pass the fourth access address to the core network after receiving it, thus ensuring the flexibility of terminal service access.

[0238] S406. The first network unit sends a first notification message to the second network unit, the first notification message carrying the fourth access address, the second identification information, the third identification information and the terminal identifier;

[0239] It is understandable that after the fourth network unit completes the transfer and deployment of the computing task, the first network unit can send the information related to the transferred and deployed computing task to the second network unit. The first notification message sent may include the fourth access address of the computing task, the second identification information of the terminal's computing task (e.g., computing task identifier (identity, ID)), the third identification information of the computing task instance, and the terminal identifier (e.g., NGAP-UE-UL / DL-ID, etc.).

[0240] S407, The first network unit receives the second response sent by the second network unit;

[0241] S408. Send a Session Resource Setup Request (PDU) to the fourth network unit;

[0242] S409. Receive the Session Resource Setup Request (PDU) sent by the fourth network unit;

[0243] Specifically, the second network unit in the core network can interact with the fourth network unit that has deployed computing tasks by sending signaling messages. The second network unit can notify the fourth network unit of the fourth access address of the computing task through extended signaling. The second network unit sends a PDU Resource Setup Request to the fourth network unit, carrying second extended information, including the fourth access address, second identification information, a list of network units, and identification information of at least one base station. The list of network units includes at least one base station. After receiving the second extended information, the fourth network unit reduces latency, improves task processing efficiency, and effectively enhances service access continuity and flexibility in the interaction between the terminal, the second network unit, and the fourth network unit. Understandably, the signaling content specifically includes: a PDU sessionmodification command and a message definition.

[0244] The PDU session modification command is sent by the SMF to the UE to indicate a change in the PDU session.

[0245] Message type:PDU ESSION MODIFICATION COMMAND

[0246] Significance: dual

[0247] Direction: network to UE.

[0248] Specifically, as shown in Table 4, which contains the PDU session communication message content, can be represented as follows:

[0249] Table 4

[0250]

[0251] S410, the first network unit sends a response to the second request to the third network unit;

[0252] S411, The second network unit sends a session modification command (PDU Session ModificationCommand) to the terminal;

[0253] S412, Receive the session modification response (PDU Session Modification Response) sent by the terminal;

[0254] In the above steps, after the second network unit completes the signaling interaction with the fourth network unit, the second network unit can send a PDU Session Modification Command to the terminal. After the terminal completes the session modification, it sends a PDU Session Modification Response to the first network unit. This completes the update of the data transmission channel between the terminal and the second network unit, improving the flexibility of the service access process, enabling rapid information exchange, and effectively reducing latency.

[0255] S413, The terminal switches from a mobile connection with the third network unit to a mobile connection with the fourth network unit;

[0256] S414, Terminal access for executing computing tasks.

[0257] In the above embodiment, terminal movement triggers computing task migration. The third network unit allocates an access address for the computing task, which is then passed by the second network unit to the fourth network unit to which the terminal is to be migrated. The first network unit triggers the fourth network unit to deploy the computing task. Subsequently, the first network unit notifies the second network unit of relevant messages about the computing task. The second network unit completes the establishment of a session resource with the fourth network unit, and during the session resource establishment process, this relevant information is carried as second extended information and passed to the fourth network unit. Thus, the computing task migration of the terminal across the third, first, and second network units is realized, and the computing task is deployed to the fourth network unit, realizing the migration of computing task deployment during the terminal network migration process. Among these, the aforementioned second extended information can maintain the continuity of terminal service access.

[0258] Optionally, after receiving the first response sent by the fourth network unit, the method further includes:

[0259] Send a first notification message to the second network unit, the first notification message carrying the fourth access address, the second identification information, the third identification information and the terminal identifier;

[0260] Receive the second response sent by the second network unit;

[0261] Send the response information of the second request to the third network unit.

[0262] It is understood that this embodiment of the present application is specifically described in the relevant descriptions in the above embodiments of the present application, and will not be repeated here to avoid repetition.

[0263] Optionally, after performing the first operation when the first request does not carry the first access address, the method further includes:

[0264] Send the second access address or the third access address to the second network unit.

[0265] It is understood that this embodiment of the present application is specifically described in the relevant descriptions in the above embodiments of the present application, and will not be repeated here to avoid repetition.

[0266] Optionally, after performing the first operation when the first request does not carry the first access address, the method further includes:

[0267] Send the second access address or the third access address to the second network unit.

[0268] It should be noted that when the second network unit in the core network does not assign a first access address to a computing task, the access address for the computing task can be assigned by either the first or third network unit. After assigning the access address to a specific computing task, the first network unit can notify the second network unit of the specific second access address. If the access address is a third access address assigned by the third network unit, the third network unit first sends the third access address to the first network unit, and then the first network unit sends it to the second network unit. In this way, the second network unit can allocate computing resources based on the received second or third access address, providing flexibility in service access.

[0281] Send a second response to the first network unit.

[0282] Optionally, after sending the second response to the first network unit, the method further includes:

[0288] It is understood that the specific implementation of this embodiment can be found in the foregoing. Figure 1 , Figure 4 and Figure 5 The relevant descriptions in the embodiments shown in the Chinese method are not repeated here to avoid repetition.

[0289] Please see Figure 7 , Figure 7 This is a flowchart illustrating a service access method applied to a third network unit in an embodiment of this application. The third network unit is a network unit in an access network. The method includes:

[0290] S501, Perform a second operation or a third operation; wherein, the second operation includes receiving a first decision instruction sent by a first network unit, and deploying a computing task instance based on the first decision instruction, the first network unit being a network unit in the access network; the third operation includes receiving a second decision instruction sent by the first network unit, and determining that the computing task instance is deployed by the terminal;
