Idle Mode Handoff Transfer of Non-LTE Network Access Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Providing network access information for non-LTE communication services to wireless devices over LTE wireless links can consume excessive bandwidth and resources, especially when broadcast without regard to actual device demand.
Innovation Solution
A communication system that detects handoffs of wireless communication devices from one LTE access node to another and transfers necessary network access information for non-LTE networks, optimizing the transfer process to conserve resources by directing it only to devices in need.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network access information is broadcast to all wireless devices over LTE links, then all devices can potentially access non-LTE networks, but bandwidth and wireless resources are excessively consumed
Solution Approach 1:
The patent segments the target audience for network access information by identifying specific subsets of devices (those in idle mode undergoing handoff) rather than broadcasting to all devices. This segmentation allows selective delivery of information only to devices that need it, reducing overall bandwidth consumption while maintaining access capability for relevant devices.
Solution Approach 2:
Devices in idle mode perform self-identification through handoff events, allowing the network to automatically recognize which devices need non-LTE network access information. The system uses the devices' own handoff behavior as a trigger mechanism, eliminating the need for continuous broadcasting to all devices.
2Adaptability or versatility
If network access information is continuously provided to all devices, then devices can access non-LTE networks at any time, but wireless resources are wasted on devices without actual demand
Solution Approach 1:
Instead of continuous information provision, the system uses periodic triggers based on handoff events. Network access information is transferred only at specific moments when devices transition between access nodes in idle mode, providing availability on-demand rather than continuous broadcasting, thus reducing resource consumption.
Solution Approach 2:
The system uses handoff detection as feedback to determine when and to which devices to transfer network access information. The network monitors device behavior (handoff events) and uses this feedback to selectively provide information only to devices that are actively moving between nodes, matching resource provision to actual demand.
3Loss of energy
If network access information is transferred only during handoff events, then bandwidth consumption is reduced, but devices not undergoing handoff cannot access non-LTE networks
Solution Approach 1:
Devices that need non-LTE network access information self-identify through their handoff behavior. The handoff event serves as an automatic trigger that reveals which devices need the information, eliminating the need for continuous probing or broadcasting to determine device needs.
Solution Approach 2:
The system performs preliminary information transfer during handoff events, preparing devices with non-LTE network access information before they actually need to access those networks. This preliminary action ensures devices are ready when needed, while the handoff timing naturally identifies which devices require preparation.

AI summary
Systems, methods, and software for providing network access information to a wireless communication device are provided herein. In one example, method of operating a communication system is provided. The method includes communicating with a wireless communication device over a long-term evolution (LTE) wireless communication link provided by a first wireless access node, detecting a handoff from the first wireless access node to a second wireless access node for the wireless communication device when the wireless communication device is in an idle mode of operation, and responsive to the handoff, transferring network access information for a non-LTE network to the wireless communication device.
