Wireless Mobility Gateway Packet Routing Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional Mobile Core Network architecture is inefficient in forwarding IP packets, leading to suboptimal data routing, increased bandwidth usage, and higher latency due to the need for packets to traverse long distances through national, regional, or metropolitan IP networks, and lacks information for advanced services like location-based services.
Innovation Solution
The Wireless Mobility Gateway (MOGW) system determines wireless connections, authenticates users, and directly routes packets to the Internet and Corporate Networks, using a special tunnel identifier to efficiently forward packets and enable mobility between geographical areas, thereby simplifying network management and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If packets are forwarded through the conventional GGSN architecture, then network coverage and connectivity are maintained, but routing efficiency deteriorates and latency increases
Solution Approach 1:
The patent segments the network functionality by introducing a Mobility Gateway that separates mobility management from packet routing. The Mobility Gateway handles authentication and connection management, while packet routing is optimized through direct peering connections, dividing the network into functional segments that operate independently to improve overall efficiency.
Solution Approach 2:
The Mobility Gateway acts as an intermediary between mobile terminals and external IP networks. It performs authentication, authorisation, and accounting functions while enabling direct optimized routing paths, serving as a mediator that improves packet forwarding efficiency without requiring changes to the core network architecture.
2Area of stationary object
If GGSN is placed far from mobile users to provide wide coverage, then network coverage is improved, but traffic latency increases
Solution Approach 1:
The patent introduces a new dimensional approach by implementing direct peering connections between Mobility Gateways and external networks at multiple geographical locations. This creates parallel routing dimensions, allowing traffic to be routed through the nearest available gateway rather than forcing all traffic through a centralized distant GGSN, thereby reducing latency while maintaining wide coverage.
3Loss of energy
If direct routing between mobile terminals is implemented, then bandwidth efficiency is improved, but network architecture complexity increases
Solution Approach 1:
The Mobility Gateway is designed as a universal node that performs multiple functions: authentication, authorisation, accounting, and direct packet routing. This multi-functionality allows direct routing between mobile terminals without requiring separate specialized devices for each function, thereby improving bandwidth efficiency while limiting the increase in overall system complexity.
4Reliability
If conventional GGSN architecture is used, then network stability is maintained, but location-based services cannot be deployed
Solution Approach 1:
The patent introduces dynamic capabilities to the network architecture through the Mobility Gateway, which can adaptively manage connections and routing based on real-time requirements. The gateway maintains stable core functions while dynamically enabling new services like location-based services through its direct network access and mobile terminal information awareness, allowing the network to evolve without sacrificing stability.

AI summary
A Wireless Mobility Gateway (MOGW) creates a wireless connection to allow a mobile terminal to perform IP packet transmission and reception and make use of mobile data services. The MOGW is able to directly route packets to the Internet and Corporate Networks, thus rendering the whole mobile network more efficient and simpler to construct and manage. The MOGW generates a special tunnel identifier to identify the wireless connection that must be contained in all packets received from the RAN. The MOGW generates such a tunnel identifier by concatenating a number of values that characterize the connection. Therefore, simply by reading this tunnel identifier, the MOGW can more efficiently forward packets appropriately. The Mobility protocol and function between MOGWs allows Mobile terminals to easily move between geographical areas served by different MOGWs.
