Mobility Support Server for Seamless Wireless Internet Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless Internet systems face challenges in providing seamless mobility support for devices moving between indoor and outdoor environments, as they often experience disruptions in network connectivity and service quality due to limitations in handover and roaming technologies across different network types and protocols.
Innovation Solution
A mobility support server system that manages and coordinates network access for devices by selecting the most suitable indoor or outdoor wireless Internet and IoT networks based on service conditions, including network type, service quality, access node terminals, ubiquitous things, and communication modes, ensuring continuous internet service through intelligent handover and roaming mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional handover and roaming technologies are used across different network types and protocols, then network connectivity can be maintained, but service quality deteriorates due to disruptions and limitations when devices move between indoor and outdoor environments
Solution Approach 1:
The patent introduces a mobility management entity (MME) as an intermediary component that coordinates handover and roaming processes across different network types (3GPP and non-3GPP networks). The MME receives mobility management messages from access node terminals, determines appropriate service conditions, and manages the handover process between networks, thereby maintaining service quality while adapting to different network protocols and types.
2Adaptability or versatility
If seamless mobility support is provided across multiple network types and protocols, then adaptability improves, but system complexity increases due to the need to manage diverse network protocols and handover mechanisms
Solution Approach 1:
The mobility management entity (MME) is designed as a universal component that handles multiple network types (3GPP and non-3GPP) and various protocols through a unified interface. The MME can process mobility management messages from different access node terminals and manage handovers across diverse network types using a single multi-functional system, thereby reducing overall system complexity while maintaining broad adaptability.
3Reliability
If manual intervention and complex network configurations are used to maintain connectivity, then service stability can be achieved, but ease of operation deteriorates due to the need for manual configuration and intervention
Solution Approach 1:
The system enables self-service mobility management where the mobility management entity (MME) automatically determines service conditions, selects appropriate networks, and executes handover processes without manual intervention. The MME autonomously processes mobility management messages, evaluates network conditions, and manages connectivity transitions, thereby maintaining service stability while eliminating the need for manual configuration and user intervention.
