Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks implement mobility management settings on a network-wide basis, leading to substantial overhead burdens and inefficient resource utilization, as they rely on GTP tunneling which is not necessary for all devices or applications.
Innovation Solution
The solution involves dynamically programming network elements to address mobility management on an individual basis for wireless devices and their applications, allowing for different mobility techniques to be used based on device type, application requirements, and context information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GTP tunneling is used for mobility management, then IP address continuity is preserved during handover, but network overhead and resource consumption increase substantially
Solution Approach 1:
The patent applies local quality by differentiating mobility management approaches based on device characteristics and application requirements. Instead of uniformly applying GTP tunneling to all devices, the system selectively applies tunneling only where needed (for mobile devices requiring IP continuity) while using simpler IP reassignment for stationary devices, thereby reducing overall network overhead while maintaining reliability where required.
Solution Approach 2:
The system dynamically determines whether to apply GTP tunneling or alternative mobility management based on real-time assessment of device mobility patterns, application requirements, and network conditions. This dynamic approach allows the network to adaptively switch between tunneling and non-tunneling modes, optimizing the balance between IP continuity and resource consumption.
2Adaptability or versatility
If GTP tunneling is applied network-wide, then all devices maintain IP address during mobility, but network complexity and processing burden increase
Solution Approach 1:
The patent segments the network into different mobility management domains based on device types and service requirements. It introduces separate mobility management entities that can independently determine whether to apply GTP tunneling or alternative methods, thereby reducing overall network complexity while maintaining versatile mobility support for different device categories.
Solution Approach 2:
The system changes the mobility management parameter (tunneling vs. non-tunneling) based on device characteristics, application requirements, and network conditions. This parameter-based differentiation allows the network to provide adaptable mobility support without imposing uniform complexity across all network elements.
3Reliability
If tunneling is used for all devices, then seamless handover is ensured, but resource efficiency decreases for stationary devices
Solution Approach 1:
The patent enables devices to self-identify their mobility characteristics and service requirements, allowing the network to automatically select the appropriate mobility management method. Stationary devices can opt out of tunneling mechanisms, thereby improving resource efficiency while mobile devices continue to receive seamless handover support through selective tunneling application.
