Prioritized Load Balancing via Random Number Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face overload issues due to simultaneous high bandwidth requests from multiple access terminals, leading to rejected requests and instability, as they rely solely on signal strength for network selection without effective load balancing.
Innovation Solution
A mobile communication device with a wireless module and controller that generates a random number to determine if it belongs to a restricted priority level, suspending reselection to another service network when it does, thereby controlling the number of access terminals transferring between networks and preventing ping-pong effects by activating prioritized load balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access terminals continuously reselect service networks based on signal strength, then terminal connectivity is maintained, but network overload increases and system stability deteriorates
Solution Approach 1:
The patent introduces a random number generation mechanism that changes the decision parameter from pure signal strength comparison to a probabilistic selection based on signal strength and random factors. This parameter change prevents deterministic flocking behavior and achieves more uniform load distribution across service networks, resolving the contradiction between maintaining connectivity and preventing overload.
Solution Approach 2:
The patent implements a preliminary random number generation step before the reselection decision is made. This preliminary action introduces randomness into the process, preventing terminals from consistently choosing the same network even when signal strength conditions are favorable, thereby avoiding network congestion and maintaining system stability.
2Productivity
If multiple access terminals request high bandwidth simultaneously, then data communication demand is met, but network overload occurs and request rejection increases
Solution Approach 1:
The patent applies preliminary random number generation to the bandwidth request process. Terminals that generate random numbers indicating restricted priority levels are prevented from making high bandwidth requests during network congested periods. This preliminary filtering action reduces the total demand on the network during peak times, preventing overload while maintaining request acceptance for terminals that pass the random number check.
3Adaptability or versatility
If access terminals frequently transfer between service networks, then network selection optimization is achieved, but ping-pong effect occurs and system stability decreases
Solution Approach 1:
The patent changes the reselection parameter by incorporating random number generation alongside signal strength comparison. This parameter modification introduces uncertainty into the reselection process, preventing terminals from oscillating between networks based on minor signal fluctuations. The random element ensures that even if signal conditions are marginal, terminals will not consistently switch networks, thereby eliminating ping-pong effects while maintaining reasonable network selection flexibility.
Data Source
AI summary
A mobile communication device for prioritized load balancing is provided. In the mobile communication device, a wireless module receives data communication services and a broadcast message from a first service network. Also, a controller determines whether the broadcast message has load balancing information for the first service network and a second service network, and in response to the broadcast message having the load balancing information, generates a random number and determines whether the random number belongs to a restricted priority level according to the load balancing information. The controller further suspends a reselection from the first service network to the second service network, in response to the random number belonging to the restricted priority level.
