Mobile Terminal Mobility Management in Cellular Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile radio networks face inefficiencies due to restricted mobility requirements not being considered, leading to unused resources when mobile terminals are in preferred areas, resulting in unnecessary capacity usage and potential need for network expansion.
Innovation Solution
Implementing a method that restricts mobility management functionality by excluding radio cell handover in mobile terminals, using identifiers to signal and differentiate between full and reduced mobility management, allowing for direct forwarding of communication links and optimizing resource usage in preferred areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If full mobility management with radio cell handover is implemented for all mobile terminals, then terminal mobility and communication continuity are improved, but network resource utilization deteriorates in preferred areas
Solution Approach 1:
The patent applies local quality by differentiating mobility management based on terminal location. Terminals in preferred areas receive reduced mobility management (no handover), while terminals in other areas receive full mobility management. This localized differentiation optimizes network resources in specific regions without compromising overall system functionality.
Solution Approach 2:
The patent segments the mobile network into preferred areas and non-preferred areas, applying different mobility management policies to each segment. This segmentation allows the network to treat different regions differently, reducing handover operations in preferred areas while maintaining full mobility management elsewhere.
2Loss of energy
If mobility management functionality is restricted for terminals in preferred areas, then network resource utilization is improved, but terminal mobility and communication continuity deteriorate
Solution Approach 1:
The patent implements local quality by providing reduced mobility management specifically for terminals located in preferred areas, while maintaining full mobility management for terminals in other areas. This localized approach ensures that mobility restrictions only apply where appropriate, preserving terminal mobility where needed.
Solution Approach 2:
The patent applies dynamics by making mobility management policies adaptable to terminal location. The network dynamically adjusts the level of mobility management based on whether the terminal is in a preferred area or not, allowing flexible adaptation to different operational scenarios.
3Reliability
If complete mobility management is provided to all terminals, then communication continuity is improved, but system performance requirements and investment costs increase
Solution Approach 1:
The patent applies local quality by providing complete mobility management only where necessary (non-preferred areas) and reduced mobility management in preferred areas. This differentiation maintains communication continuity where needed while reducing system performance requirements and investment costs in preferred areas.
Solution Approach 2:
The patent segments the network into areas requiring full mobility management and areas where reduced management is sufficient. This segmentation allows the system to meet reliability requirements in critical areas while reducing overall system complexity and investment costs in preferred areas.

AI summary
The method involves dividing a service area for a mobile terminal into a priority area and a remaining area, where the service area has a cellular network structure that is formed from radio cells. The usage of a service is enabled during detention of the mobile terminal in the priority area. A communication connection of the mobile terminal is carried out under elimination of radio cell transfer functionalities of a mobility management of the mobile telephone network during detention of the mobile terminal in the priority area. An independent claim is also included for a mobile telephone system comprising devices for forming a cellular mobile telephone network.
