UE Information Segmentation for Wireless Mobility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE, face challenges in distinguishing between different types of user equipment (UEs) based on their location and traffic load, which affects mobility management and resource allocation, leading to inefficiencies in handover processes and traffic balancing.
Innovation Solution
A method and apparatus for categorizing UEs based on their geographical distribution and traffic load, where information about UEs located at cell borders and within cell coverage is transmitted between eNodeBs, enabling more precise mobility setting changes and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE information is transmitted without categorization, then the transmission process is simple, but mobility management and resource allocation efficiency are poor
Solution Approach 1:
The patent segments UE information into different categories (first type UEs at cell borders and second type UEs within cell coverage) and transmits them separately. This segmentation enables the network to apply different management strategies for different UE types, improving mobility management efficiency and resource allocation while maintaining manageable transmission complexity through structured categorization.
2Productivity
If all UE information is transmitted uniformly, then the transmission mechanism is simple, but traffic load balancing is inefficient
Solution Approach 1:
The patent applies local quality by transmitting different UE information with different levels of detail based on their location and type. Cell border UEs receive specialized information for handover optimization, while intra-cell UEs receive different information for traffic load management. This differentiated approach improves traffic load balancing efficiency by tailoring information transmission to local network conditions and UE requirements.
3Measurement precision
If detailed UE location information is transmitted, then mobility management precision is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the necessary UE information based on UE type and location. For cell border UEs, it transmits handover-related parameters, while for intra-cell UEs, it transmits traffic load parameters. This extraction approach maintains high measurement precision for mobility management by selecting relevant parameters rather than transmitting all possible UE data, thereby reducing information transmission overhead.

AI summary
A method and apparatus for transmitting information on user equipments (UEs) in a wireless communication system is provided. A first eNodeB (eNB) transmits information on a first type of UEs and information on a second type of UEs to a second eNB. The first type of UEs is UEs located around a cell border between a first cell, controlled by the first eNB, and a second cell, controlled by the second eNB. The second type of UEs is UEs located at the other part of coverage of the first cell and the second cell.
