Access Control Entity for Hybrid Network Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where mobile users and hybrid users compete for radio resources, existing home gateways fail to efficiently manage bandwidth, leading to resource shortages and potential packet loss, especially when LTE access has a low Quality of Service (QoS) class, causing fluctuations in bundled access and reduced bandwidth.
Innovation Solution
An access control entity is introduced to monitor radio cell overload and reduce data load via hybrid network access entities, allowing mobile users to maintain radio resources by reducing bandwidth for hybrid users, with the option to switch to alternative access points, thereby preventing packet loss and maintaining network stability.

Engineering Contradiction Analysis
1Quantity of substance
If home gateways bundle multiple access technologies (LTE and xDSL) to increase bandwidth, then user bandwidth is improved, but radio resources become scarce and mobile users compete with hybrid users leading to resource shortages
Solution Approach 1:
The system dynamically changes the data load parameter for hybrid network access entities based on radio cell overload conditions. When overload is detected, the access control entity requests hybrid gateways to reduce their data load towards the overloaded radio cell, thereby adjusting resource consumption parameters to maintain system reliability
Solution Approach 2:
The system implements a feedback mechanism where the access control entity receives overload information from radio cells and sends requests to hybrid network access entities to adjust their data load. This closed-loop feedback ensures that radio resource availability is maintained by continuously monitoring and responding to overload conditions
2Adaptability or versatility
If LTE access in home gateway has low QoS class to allow flexible bandwidth usage, then adaptability is improved, but traffic may be dropped and packets retransmitted leading to connection instability
Solution Approach 1:
The system takes preliminary action by proactively detecting radio cell overload conditions before they lead to packet loss. The access control entity receives overload information and requests data load reduction in advance, preventing the need for packet retransmission and maintaining connection stability
Solution Approach 2:
The system applies preliminary anti-action by preventing packet loss through proactive load management. When overload is detected, the system reduces data load before critical resource exhaustion occurs, thereby preventing the harmful effect of packet drops and connection instability
3Reliability
If access control entity monitors and reduces data load on overloaded radio cells, then radio resource availability for mobile users is improved, but bandwidth for hybrid users is reduced
Solution Approach 1:
The system applies local quality by differentiating treatment between mobile network access entities and hybrid network access entities. Mobile users maintain their data load while hybrid users are requested to reduce their data load towards overloaded radio cells, creating localized quality adjustments that protect mobile resource availability while managing hybrid user bandwidth
