Dynamic Mobile Network Load Balancing via Real-Time Gateway Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile network access load balancing methods do not account for the actual temporal load of gateways, leading to over-utilization of high-priority gateways and under-utilization of low-priority ones, resulting in degraded service for mobile terminals.
Innovation Solution
A network access load balancing controller that receives performance status information from mobile network access gateways, calculates dynamic performance scores, and assigns gateways based on weighted rankings to optimize load distribution and maximize network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-determined weights and priorities are assigned to gateways based on fixed characteristics, then gateway selection is simplified and deterministic, but load distribution becomes unbalanced and service quality degrades due to over-utilization of high-priority gateways
Solution Approach 1:
The patent implements dynamic gateway selection by continuously monitoring performance metrics (response time, throughput, load) and adjusting gateway rankings in real-time. The MME queries the DNS system for current performance data and selects gateways based on contemporaneous conditions rather than fixed pre-assigned priorities, resolving the contradiction between operational simplicity and service quality reliability
Solution Approach 2:
The system establishes a feedback loop where the DNS system continuously collects performance status information from gateways, updates performance scores based on current load conditions, and provides this information back to the MME for informed gateway selection. This feedback mechanism ensures that gateway selection adapts to actual network conditions while maintaining automated operation
2Productivity
If fixed priority gateways are over-utilized to maximize their usage, then network capacity is fully leveraged, but service quality degrades due to gateway overload and increased latency
Solution Approach 1:
The DNS system continuously monitors gateway performance metrics including response time, throughput, and current load status. When a high-priority gateway becomes over-utilized, the system detects performance degradation through ongoing measurements and dynamically adjusts gateway rankings to redirect traffic to alternative gateways, thereby maintaining both high capacity utilization and acceptable service quality
Solution Approach 2:
The system changes the operational parameters of gateway selection by transitioning from fixed priority values to dynamic performance-based scoring. The DNS system calculates performance scores based on current gateway conditions (response time, throughput, load) and adjusts the effective priority of each gateway in real-time, allowing the network to fully leverage available capacity while preventing any single gateway from becoming a bottleneck
