Architectural Requirements

AR1

Support 5G slice creation by intent based network

Use intent based network to create 5G slice.

AR2

Support Intent instance LCM operations

provide functions for intent instance create, terminate, and KPI monitoring operations.

Functional Requirements

FR1

User intent idendify

Use NLP module to parse user inputs, identify user intent and extract the key information.

FR2

Intent Translation

Translate high-level of abstraction to a more concrete form in order to be validated and processed.

FR3

Intent Verification

Verify if the intent decision was executed as expected.（At present, there is no simulation verification, simple implementation, non-target solution）

FR4

Intent Decision

Decide which, if any, policies shall be executed in response to a request by another managed entity for a set of governance actions.

FR5

Intent Guarantee

Two-level closed loop and two-level monitoring

Intent-based Network

The list of Actors and System Components that participate in the Use Case

Short overview of the Use Case

The Intent-based Network (IBN) is applied to the configuration and optimization of network functions based on the Intents. The current version of IBN is applied to the opening and closed-loop operation of network slices in the 5G use case.

Component name

Impacted  detail

AAI

Need to add new object definition in AAI schema, including intent instance, intent solution and intent solution parameter.

UUI

A new page is needed in UUI, which user can input network requirement by human-nature language,  then the new page sends the user input to IBN componet and displays the response information to user. This procedure may be repeated multiple times until the conversation is completed and a new intent is formed in IBN component.
