Dynamic Mobility Anchor Allocation for Home Network Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network systems face challenges in efficiently allocating mobility anchors, leading to increased hardware requirements and costs due to uneven load distribution and communication disruptions when mobile nodes change home agents, especially with a large number of mobile devices.
Innovation Solution
A home network system that dynamically allocates mobility anchors based on predicted communication load data from both mobile nodes and anchors, ensuring that each node is assigned an anchor with a load within predetermined limits and minimizing maximum load, thereby optimizing load distribution over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mobility anchor is used to transfer packets, then the system is simple to manage, but the load is concentrated on the mobility anchor causing performance degradation
Solution Approach 1:
The patent divides the single mobility anchor function into multiple mobility anchors (HA1, HA2, HA3). Each mobility anchor handles a portion of the mobile nodes, segmenting the load distribution. This is achieved by introducing a mobility anchor allocation function that assigns different mobile nodes to different mobility anchors based on load conditions, thereby resolving the contradiction between simple management and high productivity.
2Productivity
If multiple mobility anchors are provided to distribute load, then the packet transfer capability increases, but the system complexity and hardware requirements increase
Solution Approach 1:
The patent introduces a mobility anchor allocation function as an intermediary between mobile nodes and multiple mobility anchors. This allocation function manages the assignment of mobile nodes to appropriate mobility anchors based on load conditions, simplifying the overall system management while enabling efficient load distribution across multiple anchors. The intermediary handles the complexity of coordinating multiple anchors, allowing them to work together seamlessly.
3Device complexity
If mobility anchors are allocated statically, then the system is easy to manage, but communication disruptions occur when mobile nodes change home agents
Solution Approach 1:
The patent implements dynamic mobility anchor allocation where the assignment of mobile nodes to mobility anchors changes based on real-time load conditions. The mobility anchor allocation function continuously monitors the load status of each mobility anchor and reassigns mobile nodes dynamically to maintain optimal load distribution. This dynamic approach ensures communication continuity even when mobile nodes change home agents, as the allocation function can redirect traffic to appropriate anchors without disruption.
4Quantity of substance
If the number of mobility anchors is increased to accommodate more mobile nodes, then the system capacity increases, but the hardware costs and management overhead increase
Solution Approach 1:
The patent combines the functions of multiple mobility anchors into a coordinated system managed by a mobility anchor allocation function. Instead of requiring separate, independently managed anchors, the system merges their operations under a unified allocation mechanism that optimizes load distribution. This allows the system to accommodate more mobile nodes using existing mobility anchor resources more efficiently, reducing the need for additional hardware while increasing capacity.

AI summary
Provided is a home network system in which an appropriate mobility anchor is allocated for a mobile node and the number of mobility anchors can be reduced. A subscriber information accumulation server (14) accumulates first communication load prediction data for each time of a mobile node (32). An anchor information accumulation server (15) accumulates second communication load prediction load for each time of each mobility anchor (11). When “a mobility anchor allocation request” is transmitted from the mobile node (32) to an anchor allocation server (13), the anchor allocation server (13) adds the first communication load prediction data and the second communication load prediction load data so as to obtain third communication load prediction data. Among a plurality of mobility anchors (11), a mobility anchor in which the third communication load prediction data is not greater than the load upper limit value at all the times and the maximum value of the second communication load prediction data is minimum is selected and allocated.
