Network Slice State Vector for Geographical Area Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slice management technologies cannot efficiently adjust the administrative, operational, and availability states of network slices within specific geographical areas, leading to incomplete control over resource allocation and service provisioning, especially in multi-vendor environments where fine-granular control is necessary.
Innovation Solution
The implementation of a mechanism that allows for the adjustment of network slice states, including administrative, operational, and availability states, within a limited geographical area by using a slice-specific state vector associated with each network resource, enabling granular control over network slices supported by radio access and core network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slice states are adjusted globally across the entire network, then comprehensive control is achieved, but fine-granular control in specific geographical areas is lost
Solution Approach 1:
The patent segments the network slice state management by introducing a slice-specific state vector for each network resource (cell, tracking area, core network resource). This allows the network to be divided into manageable geographical units, each with its own state control, enabling fine-granular adjustment without managing the entire network as a single complex entity
Solution Approach 2:
The patent implements local quality by allowing different state attributes (administrative state, operational state, availability status) to be independently configured for each network resource within a geographical area. This enables tailored state management for specific regions while maintaining overall network coherence, resolving the contradiction between global control and local granularity
2Productivity
If network slice states are adjusted in limited geographical areas, then resource allocation efficiency is improved, but control coverage is reduced
Solution Approach 1:
The patent implements dynamic state adjustment by allowing the network slice states to be flexibly modified in specific geographical areas based on local requirements. The state vector can be dynamically updated for individual cells, tracking areas, or core network resources, enabling efficient resource allocation where needed while maintaining coverage elsewhere through the hierarchical state management structure
3Adaptability or versatility
If multi-vendor environment support is implemented, then system versatility is improved, but coordination complexity increases
Solution Approach 1:
The patent implements universality through a standardized state vector structure that can represent network slice states across different vendors and network resource types. The common state attributes (administrative state, operational state, availability status) provide a universal interface for managing network slices in multi-vendor environments, reducing coordination complexity by establishing consistent state representation across diverse systems
