Route Optimization for Multi-Access Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route optimization technologies are inadequate for multi-access scenes, where mobile nodes with multiple network interfaces accessing different access points, leading to increased data transmission delays and network bandwidth consumption.
Innovation Solution
A method and apparatus that optimize data transmission paths in multi-access scenes by detecting the current communication scene and sending route optimization indications to the appropriate Mobile Access Gateways (MAGs) to ensure that data is routed directly between MAGs, bypassing the Local Mobility Anchor (LMA), thereby reducing delays and bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If data is routed through LMA in multi-access scenes, then route compatibility is maintained, but data transmission delay increases and bandwidth consumption increases
Solution Approach 1:
The patent implements dynamic route optimization by enabling mobile nodes to dynamically select between direct MAG-to-MAG routing and LMA-mediated routing based on real-time network conditions and access scenarios. The system dynamically adjusts routing paths without requiring complex manual configuration, resolving the contradiction between reducing transmission delay and maintaining route compatibility.
Solution Approach 2:
The patent introduces a route optimization indicator mechanism where the LMA acts as an intelligent intermediary that provides routing guidance to mobile nodes. Instead of the LMA directly forwarding all data (increasing delay), it sends optimization indicators that enable direct routing when appropriate, while maintaining the ability to fallback to LMA-mediated routing when needed, thus balancing speed and compatibility.
2Loss of energy
If direct MAG-to-MAG routing is implemented, then bandwidth consumption is reduced, but compatibility with existing single-access protocols is compromised
Solution Approach 1:
The patent creates a universal routing framework that functions in both single-access and multi-access scenarios. The mobile node and MAGs are designed with multi-functionality to handle both direct routing (for bandwidth efficiency) and LMA-mediated routing (for compatibility), allowing the same system to adapt to different access scenarios without requiring separate protocol implementations.
Solution Approach 2:
The patent utilizes parameter changes in routing headers and protocol fields to enable direct MAG-to-MAG routing while maintaining compatibility with existing single-access protocols. By modifying specific routing parameters rather than the entire protocol structure, the system achieves bandwidth efficiency in multi-access scenes while remaining compatible with legacy single-access infrastructure.
3Productivity
If route optimization is implemented in multi-access scenes, then transmission efficiency is improved, but detection and measurement complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where mobile nodes autonomously detect their own access scenarios and determine whether direct or LMA-mediated routing is appropriate. The nodes perform self-measurement of network conditions and make routing decisions without requiring complex external detection systems, thereby improving transmission efficiency while minimizing detection complexity.
Solution Approach 2:
The patent incorporates feedback mechanisms where mobile nodes and MAGs exchange routing status information and network condition data. This feedback loop enables the system to continuously optimize routing decisions based on actual performance metrics, improving transmission efficiency while using simple, measurable parameters rather than complex detection systems.

AI summary
Disclosed are a route optimizing method and apparatus, and a computer storage medium. The method comprises: a local mobility anchor (LMA) detecting whether a current connnunications scenario is a multi-access scenario in which communications parties each have a network interface and accesses a same mobile access gateway (MAG); if a detection result is yes, the LMA detennining whether an original data MAG of any connnunications party is connected to a network interface of a communications peer end of the connnunications party; if not, the LMA sending a route optimization instruction to the original data MAG and/or a target MAG, the route optimization instruction being used for instructing the original data MAG and/or the target MAG to perform a route optimization operation on a transmission path of a packet; and if yes, the LMA sending a route optimization instruction to a co-connected MAG, the route optimization instruction being used for instructing the co-connected MAG to perform a route optimization operation on a transmission path of a packet. By using the present invention, the problem that there is no proper local route optimization solution in a multi-access scenario is solved.
