Paging Area Determination Using User Equipment Moving Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communications systems face inefficiencies in paging processes, leading to waste of air interface and inter-network interface resources, particularly due to the large tracking areas used for paging, which can result in lower connection speeds or failures, especially with the increasing use of intelligent applications.
Innovation Solution
User equipment provides reference paging information based on its moving speed to the network device, allowing the network to determine a more targeted paging area, reducing resource consumption and improving efficiency and stability by minimizing the number of cells involved in the paging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging is performed in all cells of a tracking area, then the user equipment can be reached reliably, but air interface resources and inter-network interface resources are severely wasted
Solution Approach 1:
The tracking area is segmented into multiple paging areas based on user equipment movement characteristics. Instead of paging all cells in a large tracking area, the system divides it into smaller paging areas and selects appropriate paging areas for message delivery, reducing redundant paging operations while maintaining reliability
Solution Approach 2:
Different paging areas are assigned different quality levels or priorities based on user equipment movement patterns. The system applies local quality differentiation by selecting specific paging areas rather than uniformly paging all areas, optimizing resource allocation according to actual user location probability
2Device complexity
If the tracking area size is increased to cover larger geographic regions, then fewer base stations need to be monitored, but the paging message delivery efficiency decreases and resource waste increases
Solution Approach 1:
The system dynamically determines paging areas based on user equipment movement characteristics such as moving speed. When users are stationary or moving slowly, smaller paging areas are used. When users are moving quickly, larger paging areas are selected, making the paging strategy adaptive rather than static
3Reliability
If paging is performed in a large tracking area to ensure user equipment is reached, then connection reliability is improved, but connection speed decreases due to processing overhead
Solution Approach 1:
The system performs preliminary actions by determining user equipment movement characteristics and pre-selecting appropriate paging areas before actual paging is needed. This preparation reduces processing time during actual paging operations, improving connection speed without sacrificing reliability
