Network Attachment Subsystem Automatic Service Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Next Generation Networking (NGN) architectures lack efficient mechanisms to automatically start, stop, or modify default services in response to user events, such as logon, without explicit user request or registration, limiting dynamic service delivery and customization.
Innovation Solution
The implementation of a Network Attachment Subsystem (NASS) that notifies and triggers default services, including security settings, bandwidth profiles, and application functions, based on user events like logon, using expanded e2 reference points for event notification and registration, enabling pre-configured services to be automatically activated or modified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If default services are automatically started in response to user events, then service delivery efficiency and user experience are improved, but system complexity and control overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring default services and their associated parameters (security settings, bandwidth profiles, application functions) before users log on. The NASS stores service templates and configurations in advance, allowing automatic service instantiation upon user authentication without requiring real-time service selection or configuration, thus improving service delivery efficiency while managing system complexity through pre-planning
Solution Approach 2:
The system implements self-service by enabling the NASS to automatically select and activate appropriate default services based on user authentication events and pre-defined policies. The system autonomously configures security settings, bandwidth allocations, and application functions without manual user input or intervention, allowing the network to serve itself in responding to user logon events, thereby improving productivity while reducing operational complexity
2Adaptability or versatility
If multiple default services are pre-configured and automatically activated, then service customization and adaptability are improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the service configuration into distinct modular components: service templates, security settings, bandwidth profiles, and application functions. Each service type is configured as a separate template with its own parameters, allowing the NASS to selectively instantiate and customize services based on user events without managing a monolithic complex configuration, thus achieving service customization while managing complexity through modular design
Solution Approach 2:
The system implements universality by creating multi-functional service templates that can serve multiple purposes and user types. A single service template can be configured with universal parameters (security, bandwidth, application functions) that adapt to different users and scenarios through parameter instantiation rather than creating separate configurations for each case, thereby improving adaptability while reducing management difficulty through reusable templates

AI summary
In one embodiment, a method includes receiving, by an application function (AF) implemented on a service node of a network, notification event information that includes an identification of a user, an Internet protocol (IP) address of user equipment (UE) associated with the user, and an event type, the notification event information being pushed by a network attachment subsystem (NASS) to the AF. Responsive to the notification event information flow, one or more default services specific to the user are enabled.
