Measurement and Connectivity Service Separation in 5G NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G NR technology requires improvements in the separation of connection control and measurement control functions to reduce overhead and enhance overall performance, particularly in cloud-native architectures where these functions are decoupled into separate logical entities.
Innovation Solution
The separation of connection control and measurement control into distinct logical entities within wireless communication systems, allowing for independent management and reduced overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If connection control and measurement control are integrated in a single logical entity, then device complexity is reduced, but state-management overhead increases and flexibility decreases
Solution Approach 1:
The patent divides the integrated connection control and measurement control into separate logical entities (connection service CS and measurement service MS). The CS handles connection establishment, maintenance, and release, while the MS handles measurement configuration and report collection. This segmentation reduces state-management overhead by separating the state tracking responsibilities from the measurement responsibilities, allowing each service to manage only its relevant state information.
2Adaptability or versatility
If connection control and measurement control are separated into distinct logical entities, then state-management overhead is reduced and flexibility is enhanced, but device complexity increases
Solution Approach 1:
The patent introduces a service management and orchestration (SMO) framework as an intermediary that coordinates between the connection service (CS) and measurement service (MS). The SMO handles the complex interactions and state synchronization between the separated services, providing a unified management layer that abstracts the complexity from the individual services while enabling flexible independent optimization of each service.
3Productivity
If measurement control is tightly coupled with connection control, then measurement reporting efficiency is improved, but adaptability to different network scenarios decreases
Solution Approach 1:
The measurement service (MS) is designed as a universal service that can independently serve multiple connection services (CS) and adapt to different network scenarios. The MS maintains measurement state information that is applicable across different connection contexts, allowing the same measurement configuration and reporting mechanisms to be reused across multiple connections and service types, thereby enhancing adaptability while maintaining efficiency through standardized procedures.

AI summary
Method and apparatus for interactions between measurement services and connectivity services. The apparatus establishes a first association with a CS via a first radio channel with a first eDU. The apparatus receives, via the first association, a first configuration for a second radio channel of the first eDU. The apparatus receives, via a second association with a MS, a first measurement configuration via the second radio channel. The apparatus, via the second association, transmits a first measurement report via the second radio channel based on the first measurement configuration. The apparatus is configured to receive, via the first radio channel or the second radio channel, a second configuration for a third radio channel and a fourth radio channel with a second eDU, where the second configuration comprises instructions to switch to the second eDU.
