An intent-driven cloud access network system and method

Abstract

The invention belongs to the technical field of wireless communication networks, and discloses an intention-driven cloud-based access network system and method. The service application layer obtains mobile network core applications and service demands oriented to vertical industry applications, and completes translation through an intention northbound interface; The enabling layer relies on the cloud-based network service plane to build a control system for global dynamic management and orchestration based on intent to achieve unified planning of business intent and unified scheduling of resources; the infrastructure layer uses resource virtualization technology to form a resource pool, which is based on The three major application scenarios of 5G provide ubiquitous connectivity. The present invention realizes network collaboration, resource sharing, open interface and intelligent management through intention-driven cloud-based ubiquitous extremely intelligent access network, and constructs a reconfigurable resource management architecture. The invention also discloses an intention-driven cloud-based access network implementation method, which can coordinately schedule network resources and provide end-to-end service assurance.

Description

technical field [0001] The invention belongs to the technical field of wireless communication networks, and in particular relates to an intent-driven cloud access network system and method. Background technique [0002] The future wireless communication network should have the characteristics of high functional modularization, resource sharing, open interface, intelligent management, and open capabilities, and support business-to-resource customization on demand through a powerful converged network. Software-defined network (SDN) is a new type of network architecture. Its design concept is to separate the control plane of the network from the data forwarding plane, so as to realize the programmable control of the underlying hardware through the software platform in the centralized controller. Realize flexible on-demand deployment of network resources. In an SDN network, network devices are only responsible for simple data forwarding, and general-purpose hardware can be used...

Problems solved by technology

The disadvantage of this method is that this method uses the policy string to express the business intention in the application network driver model, but only considers the representation of the intention, and does not consider whether the expressed intention is distributed in a single or multiple forms , which leads to the problem of consistency verification of intent. When multiple business intents are issued, logical consistency problems are prone to occur, which in turn leads to problems such as network configuration errors.

The shortcomings of this technology are: this method enhances user interaction with computing devices by modifying the layout of content based on user feedback, but the feedback mechanism is based on the language, methods and transformation actions of specific computer structural features. Robustness and scalability are not enough

The disadvantage of this method is that the management control role of the intent-driven controller in this method is not aimed at 5G RAN. On the one hand, this is because the controller is not integrated with the management and orchestration system; The environment is still focused on the fixed network, and has not yet migrated to the wireless communication network. Facing the diversified task requirements of the 5G era, it cannot provide efficient, flexible, and flexible management capabilities.

[0010] The continuous growth of the scale and complexity of wireless networks, as well as the diversified development of user needs and services, the rigid network architecture is closed and inflexible, and the key network technologies are divided and lack of pioneering, which cannot meet the requirements of next-generation network intelligence, simplicity, agility, Requirements for scalability, flexibility, and integration
