Unified Location ID Namespace for Fixed-Mobile Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a unified trusted location identification system complicates fixed-mobile convergence, making it impossible to use a single interface for both fixed and mobile access, especially in 5G Core Network access scenarios, even when managed by the same operator.
Innovation Solution
A communication system and method that determine trusted location identification within a communication cell using a common location ID namespace, enabling unified N2 interface for both fixed and mobile access, and integrating mobile and fixed location IDs to facilitate seamless connection management and policy management across converged networks.

Engineering Contradiction Analysis
1Reliability
If separate location identification systems are used for fixed and mobile networks, then each network can maintain its own trusted location ID, but fixed-mobile convergence becomes complicated and unified interface usage is impossible
Solution Approach 1:
The patent merges the previously separate fixed network location ID system and mobile network Cell-ID system into a unified location ID namespace. This unified namespace allows both fixed and mobile access networks to use the same location identification format, enabling fixed-mobile convergence while maintaining trusted location identification through operator-controlled assignment.
Solution Approach 2:
The unified location ID namespace is designed to serve multiple functions simultaneously: it works for both fixed and mobile access networks, supports both NGA framework and 3GPP framework, and enables both separate and converged network operations. This universal design eliminates the need for separate location ID systems while maintaining all required functionalities.
2Adaptability or versatility
If a unified location ID namespace is introduced for fixed-mobile convergence, then interface unification becomes possible, but the complexity of managing both fixed and mobile location IDs increases
Solution Approach 1:
The patent applies local quality by allowing the location ID format to adapt to different network contexts. Within the unified namespace, the structure can represent either fixed network locations or mobile network locations depending on the specific assignment, enabling interface unification without requiring complex format switching or conversion mechanisms.
