Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile computing power network, in particular to a real-time perception method of endogenous computing power resources in a mobile computing power network. BACKGROUND

[0002] Computing power network is a network data forwarding method that introduces computing power information. Through information perception of user service demand, computing power resources and network resources, it dynamically selects a "forwarding path + destination service node" that meets the service demand, and dispatches the service along the specified path to the service node, thereby realizing global optimization of computing power and network resources. The computing task scheduling of the computing power network considers the availability, computing capacity, load condition of each computing power node, as well as the priority and resource demand of the task, and allocates the computing task to the appropriate computing power node. According to the computing power node and network topology information, the optimal network forwarding path between the computing task and the computing power node is constructed to ensure that the task can be processed at the fastest speed. The computing task scheduling algorithm of the computing power network is based on the computing power information of the computing power nodes in the computing power network, which includes computing power types (such as CPU, GPU, NPU, etc.), computing power computing capacity (such as TOPS, TFLOPS, etc.), and computing power node load (such as CPU load, GPU load, etc.).

[0003] In the schematic diagram of network communication architecture, mobile communication network is designed to connect mobile users and fixed point users (or between mobile users) to realize voice and data communication. The network is composed of three main parts: wireless devices, transmission devices and core network devices. Wireless devices, including user terminals (such as smartphones, tablets) and base stations, are responsible for managing and scheduling wireless channel resources to ensure efficient forwarding of data through wireless channels while meeting mobility requirements, which means that users can maintain continuous network connection wherever they are. Transmission equipment is responsible for transmitting fixed network data between wireless base stations and core network equipment to ensure that data can flow stably and reliably between different network nodes, thereby supporting large-scale data transmission requirements. The core network equipment is the brain of the mobile communication network, responsible for managing the connection of wireless base stations, access control, registration, session establishment and mobility management of user terminals, and other key control functions; in addition, the core network equipment also handles data forwarding between user data of user terminals and external data networks (such as the Internet) to ensure that users can seamlessly access network resources and services.

[0004] Mobile computing network (Mobile Computing Network) is based on mobile communication network providing connection service, combined with ubiquitous endogenous computing power (terminal computing power, base station computing power, core network edge computing power and other computing power resources) in mobile communication network, and through management and control mechanism to coordinate connection resources and computing power resources, so as to realize on-demand computing service. Mobile computing network is the double infrastructure of connection + calculation, which is the evolution and development of computing power network in mobile communication network.

[0005] The precise and real-time scheduling of computing tasks in mobile computing network needs to perceive the change of computing power in real time. The polling query or subscription notification event acquisition mechanism in the existing mobile communication network has the defects of time-consuming connection establishment, complicated interactive message and point-to-point communication, which cannot achieve real-time perception of the computing power resources of the whole network for mobile computing network scheduling. SUMMARY

[0006] The present application provides a real-time perception method of endogenous computing power resources in mobile computing network, aiming at the problem that the polling query or subscription notification event acquisition mechanism in the existing mobile communication network cannot achieve real-time perception of the computing power resources of the whole network for mobile computing network scheduling.

[0007] The technical scheme adopted by the real-time perception method of endogenous computing power resources in mobile computing network to solve the above technical problems is as follows:

[0008] A real-time perception method of endogenous computing power resources in mobile computing network, which depends on computing power perception bus and perception data notification, wherein:

[0009] The computing power perception bus is responsible for managing and distributing the information of computing power nodes in the mobile communication network. The computing power perception bus provides two services of computing power information subscription and computing power information unsubscription for service providers. The computing power information subscription service allows service providers or management nodes in the network to subscribe to specified computing power node information. The computing power information unsubscription service allows nodes that have subscribed to computing power information to actively stop receiving data and state information related to specified computing power nodes.

[0010] The perception data notification is responsible for distributing computing power perception data. The perception data notification is transmitted in a connectionless manner, supports a mixed mode of unicast, multicast and broadcast, and is sent with low delay characteristics to ensure fast and efficient processing of data.

[0011] Optionally, the involved computing power perception bus itself adopts service SBA or message queue to realize.

[0012] Optionally, the involved computing power perception bus includes three parts of computing power registration center, computing power information provider and computing power information consumer, wherein:

[0013] The computing power registration center is a computing power registration management hub node of the mobile computing power network. In the mobile computing power network, all computing power nodes need to be initially registered in the computing power registration center, and the computing power registration center maintains a database or directory to record the current state and capability of all registered nodes.

[0014] The computing power information provider is a node providing computing power resources in the mobile computing power network. The computing power information provider registers its resources through the computing power registration center and updates the state information of the resources in real time.

[0015] The computing power information consumer is a node needing to use computing power resources. The computing power information consumer queries available computing power resources through the computing power registration center, finds a computing power information provider that can meet its demand, and subscribes to a computing power information change request from the computing power information provider to obtain the latest state and changes of the computing power resources in real time.

[0016] Further optionally, the computing power subscription process based on the computing power perception bus is described as follows:

[0017] (A1) Computing power information provider registration: the computing power information provider, i.e., the mobile computing power network computing power node, notifies the computing power registration center of its initial computing power information, including the computing power node identifier, the computing power node type, the computing power node network address, the computing power node service port number, the computing power announcement multicast address, the computing power announcement multicast port, the computing power announcement broadcast address, and the computing power announcement broadcast port.

[0018] (A2) Computing power information query: the computing power information consumer queries the computing power information provider's information from the computing power registration center, including the computing power node identifier, the computing power node type, the computing power node network address, and the computing power node service port number.

[0019] (A3) Computing power information change subscription: the computing power message consumer sends a computing power information change subscription message to the computing power information provider, and the computing power information provider stores the computing power information change subscription list locally. The computing power information change subscription message includes the notification mode, the notification times, the notification period, the announcement range, the unicast notification address, and the unicast notification port number. The notification mode is divided into single notification, multiple notification, and periodic notification. (a1) When the notification mode is single notification or multiple notification, the notification times represent the number of times of notification after the computing power information changes. (a2) When the notification mode is periodic notification, the notification period represents the periodic time of notification, with the unit of seconds. The announcement range is divided into unicast, multicast, and broadcast. (b1) Unicast means that the announcement range is unique to the computing power subscriber. (b2) Multicast means that the announcement range is multiple computing power subscribers with the same multicast IP address. (b3) Broadcast means that the announcement range is multiple computing power subscribers with the same network domain broadcast IP address.

[0020] Further optionally, the computing power unsubscription process based on the computing power perception bus is described as follows:

[0021] (B1) Initiate unsubscription request: when the computing power information consumer decides not to receive information from a certain computing power node or certain computing power nodes, it initiates an unsubscription request to the computing power registration center, which indicates the computing power node identifier and related information that needs to be unsubscribed;

[0022] (B2) Process unsubscription request: after receiving the unsubscription request, the computing power registration center updates the information of the computing power information consumer in its database or directory, and removes the subscription relationship with the specified computing power node;

[0023] (B3) Notify computing power information provider: once the unsubscription request is processed, the computing power registration center will notify the relevant computing power information provider that the computing power information consumer no longer needs to receive its computing power information updates;

[0024] (B4) After receiving the unsubscription notification, the computing power information provider updates its local storage of the computing power information change subscription list to ensure that it no longer sends information to the computing power information consumer that has canceled the subscription;

[0025] (B5) Confirmation and feedback: after the entire unsubscription process is completed, the computing power registration center sends a confirmation message to the computing power information consumer, indicating that the unsubscription operation has been successfully executed.

[0026] Further optionally, the computing power perception data notification process based on the perception data notification is described as follows:

[0027] (C1) Triggering condition:

[0028] (C1.a) If the computing power information provider receives a notification mode of periodic notification in the computing power information change subscription message: when the periodic clock arrives, the computing power information provider triggers the computing power notification;

[0029] (C1.b) If the computing power information provider receives a notification mode of single notification or multiple notifications in the computing power information change subscription message: when the computing power information of the computing power information provider changes, the computing power information provider performs computing power notification;

[0030] (C2) Notification sending: the computing power information provider sends computing power information in UDP message format according to the local storage of the computing power information change subscription list;

[0031] (C3) Notification range:

[0032] (C3.a) If the notification range in the subscription information is unicast, the computing power information provider sends a UDP unicast computing power notification message to the specified computing power information consumer;

[0033] (C3.b) If the notification scope in the subscription information is multicast, the computing power information provider sends a UDP multicast computing power information notification to a group of computing power information consumers;

[0034] (C3.c) If the notification scope in the subscription information is broadcast, the computing power information provider sends a UDP broadcast computing power information notification to the computing power information consumer in the same network domain;

[0035] (C4) The computing power information provider determines its subsequent actions based on the notification patterns in its local computing power information change subscription list:

[0036] (C4.a) If the notification mode is single notification, the computing power information provider will no longer send subsequent notifications after the number of notifications for computing power information reaches the upper limit.

[0037] (C4.b) If the notification mode is multiple notifications, when the number of notifications for computing power information has not reached the upper limit and the computing power information changes again, the computing power information provider shall issue a notification in accordance with the set notification conditions.

[0038] (C4.c) If the notification mode is periodic notification, then continue to notify according to the set period.

[0039] The real-time sensing method for intrinsic computing resources in mobile computing networks of the present invention has the following advantages compared with the prior art:

[0040] This invention utilizes two mechanisms—a computing power awareness bus and a sensing data notification—to enable mobile computing networks to perceive and adapt to changes in endogenous computing resources in real time. This makes the network more intelligent and adaptive, optimizes resource utilization, and improves overall performance and efficiency. It solves the problem that existing polling or subscription notification event acquisition mechanisms in mobile communication networks cannot achieve real-time perception of the entire network's computing resources in mobile computing network scheduling. Real-time computing power awareness is crucial for supporting computationally intensive tasks and services, especially in dynamically changing network environments. Attached Figure Description

[0041] Appendix Figure 1 This is a flowchart of the computing power subscription process based on the computing power sensing bus in Embodiment 1 of the present invention;

[0042] Appendix Figure 2 This is a flowchart of the computing power unsubscription process based on the computing power sensing bus in Embodiment 1 of the present invention. Detailed Implementation

[0043] To make the technical solution, the technical problem solved, and the technical effect of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments.

[0044] Example 1:

[0045] This embodiment proposes a real-time sensing method for the intrinsic computing power resources of a mobile computing power network. This method relies on a computing power sensing bus and sensing data announcements, wherein:

[0046] The computing power awareness bus is responsible for managing and distributing information of computing power nodes in the mobile communication network. The computing power awareness bus provides two services to service providers: computing power information subscription and computing power information unsubscription. The computing power information subscription service allows service providers or management nodes in the network to subscribe to information of specified computing power nodes, while the computing power information unsubscription service allows nodes that have subscribed to computing power information to actively stop receiving data and status information related to specified computing power nodes.

[0047] The perception data announcement is responsible for distributing computing power perception data. The perception data announcement is transmitted in a connectionless manner, supports a mixed mode of unicast, multicast and broadcast, and is sent with low latency to ensure fast and efficient data processing.

[0048] In this embodiment, the computing power awareness bus itself is implemented using Service-Based Architecture (SBA) or message queues.

[0049] The computing power awareness bus consists of three parts: a computing power registration center, computing power information providers, and computing power information consumers.

[0050] The computing power registry is the central node for the registration and management of computing power in mobile computing power networks. In mobile computing power networks, all computing power nodes (such as core network functions, base stations, terminals, etc.) need to be initially registered with the computing power registry. This process is similar to a node introducing itself to the network and providing detailed information about its computing power resources, such as processing power, storage capacity, and network bandwidth. The computing power registry maintains a database or directory that records the current status and capabilities of all registered nodes.

[0051] A computing power information provider is a node that provides computing power resources in a mobile computing power network. The computing power information provider registers its resources through the computing power registration center and updates the status information of the resources in real time.

[0052] The computing power information consumer is a node that needs to use computing power resources. The computing power information consumer queries the computing power registration center for available computing power resources and finds a computing power information provider that can meet its needs. Once a computing power information provider that meets its needs is found, the computing power information consumer subscribes to the computing power information change request to obtain the latest status and changes of computing power resources in real time.

[0053] (A) Combined with appendix Figure 1 The computing power subscription process based on the computing power awareness bus is described as follows:

[0054] (A1) Registration of computing power information providers: The computing power information provider, namely the computing power node of the mobile computing power network, announces its initial computing power information to the computing power registration center, including the computing power node identifier, computing power node type (e.g., CPU, GPU, etc.), computing power node network address, computing power node service port number, computing power announcement multicast address, computing power announcement multicast port, computing power announcement broadcast address and computing power announcement broadcast port;

[0055] (A2) Computing power information query: The computing power information consumer queries the computing power registration center for information on the computing power information provider, including computing power node identifier, computing power node type (e.g., CPU, GPU, etc.), computing power node network address, and computing power node service port number;

[0056] (A3) Computing power information change subscription: The computing power message consumer sends a computing power information change subscription message to the computing power information provider, and the computing power information provider stores the computing power information change subscription list locally; among them, the computing power information change subscription message includes notification mode, notification number, notification period, announcement scope, unicast notification address and unicast notification port number: the notification mode is divided into three types: single notification, multiple notification and periodic notification. (a1) When the notification mode is single notification or multiple notification, the notification number indicates the number of times to notify after the computing power information changes. (a2) When the notification mode is periodic notification, the notification period indicates the periodic time of the notification, in seconds. The announcement scope is divided into unicast, multicast and broadcast. (b1) Unicast indicates that the announcement scope is a single computing power subscriber. (b2) Multicast indicates that the announcement scope is multiple computing power subscribers with the same multicast IP address. (b3) Broadcast indicates that the announcement scope is multiple computing power subscribers with the same network domain broadcast IP address.

[0057] (B) Combined with Appendix Figure 2 The computing power subscription process based on the computing power awareness bus is described as follows:

[0058] (B1) Initiating an unsubscribe request: When a computing power information consumer (i.e. subscriber) decides to no longer receive information from one or more computing power nodes, it initiates an unsubscribe request to the computing power registration center. This request will specify the identifier of the computing power node to be unsubscribed and related information.

[0059] (B2) Handling unsubscribe requests: After receiving an unsubscribe request, the computing power registry updates the information of the computing power information consumer (i.e., subscriber) in its database or directory and removes the subscription relationship with the specified computing power node. This may include deleting the identifier of the computing power information consumer (i.e. subscriber), canceling the previous subscription settings, etc.

[0060] (B3) Notify computing power information providers: Once the unsubscribe request is processed, the computing power registry will notify the relevant computing power information providers (i.e., the subscribed computing power nodes) to inform their computing power information consumers (i.e., subscribers) that they no longer need to receive their computing power information updates.

[0061] (B4) After receiving the unsubscribe notification, the computing power information provider (i.e. the subscribed computing power node) updates its locally stored list of computing power information change subscriptions to ensure that it no longer sends information to computing power information consumers who have unsubscribed.

[0062] (B5) Confirmation and Feedback: After the entire unsubscribe process is completed, the computing power registration center sends a confirmation message to the computing power information consumer to inform them that the unsubscribe operation has been successfully executed; at the same time, if any problems are encountered during the unsubscribe process, the subscriber will be notified in a timely manner through the feedback mechanism.

[0063] (C) The computing power perception data notification process based on perception data notification is described as follows:

[0064] (C1) Triggering condition:

[0065] (C1.a) If the computing power information provider receives a computing power information change subscription message with the notification mode set to periodic notification: when the periodic clock arrives and a computing power announcement is triggered, the computing power information provider will issue a computing power announcement.

[0066] (C1.b) If the computing power information provider receives a notification mode of single notification or multiple notification in the computing power information change subscription message: When the computing power information provider’s computing power information changes (e.g., CPU utilization, GPU utilization, number of computing power tasks, etc.), the computing power information provider will issue a computing power notification.

[0067] (C2) Notification Sending: The computing power information provider subscribes to the list of changes in computing power information stored locally and sends computing power information using UDP message format. The computing power information adopts UDP message format and includes computing power node identifier, computing power node type (e.g., CPU, GPU, etc.), computing power load and computing power value (e.g., FLOPS floating-point operations per second, TOPS trillion operations per second, etc.).

[0068] (C3) Scope of Announcement:

[0069] (C3.a) If the notification scope in the subscription information is unicast, the computing power information provider shall send a UDP unicast computing power notification message to the designated computing power information consumer according to the unicast notification address and unicast notification port number in the subscription computing power information change notification.

[0070] (C3.b) If the notification scope in the subscription information is multicast, the computing power information provider shall send a UDP multicast computing power information notification to a group of computing power information consumers according to the computing power notification multicast address and computing power notification multicast port in the initial computing power information of the notification.

[0071] (C3.c) If the notification scope in the subscription information is broadcast, the computing power information provider shall send a UDP broadcast computing power information notification to the computing power information consumer in the same network domain according to the computing power notification broadcast address and computing power notification broadcast port in the initial computing power information of the notification.

[0072] (C4) The computing power information provider determines its subsequent actions based on the notification patterns in its local computing power information change subscription list:

[0073] (C4.a) If the notification mode is single notification, the computing power information provider will no longer send subsequent notifications after the number of notifications for computing power information reaches the upper limit.

[0074] (C4.b) If the notification mode is multiple notifications, when the number of notifications for computing power information has not reached the upper limit and the computing power information changes again, the computing power information provider shall issue a notification in accordance with the set notification conditions.

[0075] (C4.c) If the notification mode is periodic notification, then continue to notify according to the set period.

[0076] In summary, the real-time perception method for intrinsic computing resources in a mobile computing network according to the present invention can perceive and adapt to changes in intrinsic computing resources in real time, solving the problem that the polling query or subscription notification event acquisition mechanism in existing mobile communication networks cannot achieve real-time perception of the computing resources of the entire network by the mobile computing network scheduling.
