Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE networks face challenges in seamlessly transitioning mobile data sessions to unlicensed Wi-Fi access points due to compatibility issues, leading to disruptions in mobile streaming services and inefficient use of radio spectrum.
Innovation Solution
Implementing a system that facilitates secure and seamless handoff of LTE sessions to registered Wi-Fi access points by creating a mutually beneficial interoperable bridge between LTE and Wi-Fi networks, using a content handoff processor to manage session continuity and prioritize access points based on quality of service and security requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile data sessions are transitioned to unlicensed Wi-Fi access points, then LTE network congestion is reduced and bandwidth availability is improved, but compatibility issues cause session disruptions and service continuity problems
Solution Approach 1:
The patent introduces a Wi-Fi access point as an intermediary network element that bridges the licensed LTE network and unlicensed Wi-Fi network. The access point establishes separate connections with both the LTE base station and mobile device, acting as a mediator that enables seamless session transition without direct incompatibility conflicts between LTE and Wi-Fi protocols.
Solution Approach 2:
The patent segments the network connection into distinct layers: the LTE connection between base station and access point, and the Wi-Fi connection between access point and mobile device. This segmentation allows each connection to operate independently with its own protocol stack, resolving compatibility issues while maintaining end-to-end session continuity.
2Loss of energy
If LTE sessions are handed off to Wi-Fi access points, then spectrum efficiency is improved and cellular network load is reduced, but compatibility barriers prevent seamless transition
Solution Approach 1:
The Wi-Fi access point is designed with multi-functionality, serving both as a standard Wi-Fi access point for wireless devices and as an LTE network element that can establish connections with the LTE base station. This universal design enables the same device to operate in both unlicensed and licensed spectrum domains.
Solution Approach 2:
The access point serves as an intermediary that translates and bridges between LTE and Wi-Fi network protocols. It receives LTE sessions from the base station and forwards them appropriately over Wi-Fi to mobile devices, enabling seamless interoperability between the two different network types.
3Reliability
If seamless session continuity is implemented across LTE and Wi-Fi networks, then user experience is improved and service disruption is minimized, but system complexity increases due to interoperability requirements
Solution Approach 1:
The patent places the complexity management function in the Wi-Fi access point, which acts as an intermediary between the simple LTE base station and the mobile device. The access point handles all protocol translation, session management, and network coordination, keeping the overall system architecture manageable despite the interoperability requirements.

AI summary
Internet protocol session continuity can be achieved via an access point registration process. Mobile devices near an access point device that has registered with a base station device can offload wireless communication from the base station device to the access point device. The access point device can be a known access point device that can be secured and subject to session continuity policies of a service provider. The session continuity policies can be stored at a content handover processor, which can oversee the handover processes between the base station device and the mobile device.
