Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data traffic is handled by LTE base stations and gateways, then user throughput is maintained, but network congestion increases and QoS degrades
Solution Approach 1:
The patent extracts data traffic from the LTE network and redirects it to WLAN networks. The gateway detects congested data bearers and establishes corresponding data bearers in WLAN networks, thereby removing excessive traffic load from LTE base stations and gateways to prevent congestion and maintain QoS
Solution Approach 2:
The patent introduces a gateway as an intermediary between LTE and WLAN networks. The gateway performs traffic detection, congestion identification, and intelligent offloading decisions, acting as a mediator that manages data flow between the two networks to optimize overall system performance and prevent congestion
2Productivity
If network capacity is increased to handle more data, then user throughput improves, but hardware wear and power consumption increase
Solution Approach 1:
The patent extracts traffic handling functions from the LTE network infrastructure and transfers them to WLAN networks. By offloading data traffic to WLAN, the system reduces the workload on LTE base stations and gateways, thereby reducing their power consumption and hardware wear while maintaining overall network capacity
Solution Approach 2:
The patent makes the network system multi-functional by enabling it to dynamically switch between LTE and WLAN networks for data transmission. The system can route traffic through different networks based on their respective capabilities and current conditions, optimizing resource utilization and reducing energy consumption across the entire network infrastructure

AI summary
The present disclosure relates to systems, methods, and non-transitory computer-readable media for offloading data packets from a first radio access network to a second radio access network. The method comprises monitoring first values of first performance parameters of the first radio access network at different instants of time prior to a predetermined transmission time interval. Then the second values of the one or more first performance parameters are predicted based on the first values. Further, the second values are compared against corresponding predetermined threshold values of the one or more first performance parameters and based on the comparison offloading of the data packets are triggered.
