Terminal Working Area Configuration for Low-Power Mobility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems with a large number of cells, user equipment (UE) frequently performs mobility management operations such as cell selection, reselection, and measurement, leading to high power consumption.
Innovation Solution
A configuration method and apparatus that allows a terminal to receive and perform operations within a defined working area based on configuration information provided by a network side device, reducing operations outside this area to minimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE frequently performs mobility management operations (cell selection, reselection, measurement) to maintain connectivity in a large number of cells, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent divides the service area into multiple working areas, each managed by a different network side device. The terminal performs mobility management operations only within its assigned working area rather than across all cells, segmenting the mobility management task to reduce overall power consumption while maintaining communication reliability within the segmented region
Solution Approach 2:
The patent implements local mobility management by confining cell selection, reselection, and measurement operations to a specific working area rather than the entire network. This local quality approach allows the terminal to maintain reliable communication within its local area without expending energy on global mobility management
2Adaptability or versatility
If terminal performs mobility management operations across all cells to ensure comprehensive coverage, then service availability is improved, but device complexity increases
Solution Approach 1:
The patent segments the network into multiple working areas with dedicated network side devices. Each terminal is assigned to a specific working area, simplifying mobility management by reducing the scope from all cells to only the local working area, thereby reducing device complexity while maintaining service availability within the segmented region
Solution Approach 2:
The patent applies partial action by having terminals perform mobility management operations only in their assigned working area rather than across all cells. This partial coverage approach reduces computational and operational complexity while providing sufficient service availability for terminals within their designated areas
Data Source
AI summary
A configuration method includes: receiving, by a terminal, configuration information of a working area sent by a first network side device, where the working area is used for the terminal to perform a first operation; and performing, by the terminal, the first operation in the working area based on the configuration information.
