NSA Cell Migration Using NR Neighbor Access Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks with NSA and SA hybrid networking, frequent cell handovers due to reduced cell radius of 5G base stations lead to complex mobility management and difficulty in maintaining high-speed service quality, especially when NR neighbor cells do not support dual connection, causing co-channel interference and reduced user experience.
Innovation Solution
A method involving co-channel interference measurement and determination of NR neighbor cell access capabilities is implemented by NR and LTE-side base stations and mixed-mode terminals to facilitate seamless migration to NR neighbor cells with reduced signaling overhead, using methods like SnChange and Inter-RAT handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data migration is performed between storage systems with different data structures and protocols, then storage system compatibility is improved, but data migration complexity increases
Solution Approach 1:
The patent introduces a data migration apparatus as an intermediary component that mediates between different storage systems. The apparatus includes a data migration module that handles protocol conversion and data structure transformation, acting as a bridge that enables compatibility between heterogeneous storage systems without requiring direct complex integration between them.
Solution Approach 2:
The data migration process is segmented into distinct functional modules: a data migration module for handling the core migration logic, a data structure conversion module for transforming data formats, and protocol conversion capabilities. This segmentation allows each component to be optimized independently and simplifies the overall system architecture.
2Adaptability or versatility
If data migration is performed between storage systems with different data structures, then storage system versatility is improved, but migration time increases
Solution Approach 1:
The patent implements a data structure conversion module that performs preliminary conversion of data structures before the actual migration process. By pre-converting data to the target format and preparing migration templates in advance, the system reduces the time required during the actual data transfer phase, as conversion operations are performed more efficiently when done beforehand.
3Adaptability or versatility
If heterogeneous storage protocols are supported, then system adaptability is improved, but protocol conversion complexity increases
Solution Approach 1:
The data migration apparatus is designed with universal protocol conversion capabilities that can handle multiple storage protocols through a unified architecture. The system implements a standardized interface layer that can adapt to different protocols (such as NAS, SAN, object storage) without requiring separate dedicated conversion mechanisms for each protocol, thereby reducing overall system complexity.

AI summary
A migration method under hybrid networking applied to an NR-side base station in non-standalone networking (NSA)comprising: delivering co-frequency interference measurement to a mixed-mode terminal according to a configuration fora co-frequency interference measurement parameter (S101); determining, on the basis of NR neighbor cell measurement information reported by the mixed-mode terminal, whether a corresponding NR neighbor cell supports NSA access (S 102); and sending, to an LTE-side base station in the NSA, the determination result of whether the NR neighbor cell supports NSA access (S103). A migration method under hybrid networking, applied to an LTE-side base station in NSA, comprising: receiving a list of NR neighbor cells that support NSA access, wherein the list of NR neighbor cells is sent by an NR-side base station in NSA(201); detecting a signal state of each NR neighbor cell in the list of NR neighbor cells, and comparing the signal state with a handover condition (202); and after the handover condition is satisfied, triggering a mixed-mode terminal to disconnect the current connection to migrate to a corresponding NR neighbor cell (203).
