User Equipment Cellular Link Information Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in maintaining call quality due to frequent handovers between LTE and WiFi connections, leading to signal strength fluctuations and deteriorated service.
Innovation Solution
A user equipment (UE) device collects information about its cellular link and communicates this information over a short-range wireless link, such as WiFi, to the network, including base station identifiers, mobile country codes, mobile network codes, and cellular RAT details, enabling the network to provide better services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE frequently switches between LTE and WiFi connections based on signal strength, then the UE can maintain connectivity, but call quality deteriorates due to handover instability
Solution Approach 1:
The network receives feedback from the UE about cellular link quality and uses this information to make informed handover decisions. The UE reports cellular RAT information, cell identities, and signal quality metrics to the network, which then determines the optimal connection strategy to maintain call quality while ensuring connectivity.
Solution Approach 2:
The network proactively manages handovers by receiving advance information from the UE about cellular link conditions. By having the UE continuously report cellular RAT information and cell identities before handover is needed, the network can prepare and execute handovers more smoothly, reducing the harmful effects of frequent switching on call quality.
2Reliability
If the UE maintains both cellular and WiFi connections simultaneously, then connectivity is improved, but device complexity increases
Solution Approach 1:
The network acts as an intermediary that manages the complexity of dual connection management. Instead of the UE making complex decisions about when to switch or maintain both connections, the network receives cellular link information from the UE and makes the handover decisions centrally, simplifying the UE's role while maintaining connectivity reliability.
3Adaptability or versatility
If the network has accurate cellular link information, then service optimization is improved, but information collection overhead increases
Solution Approach 1:
The invention extracts only the essential cellular link information needed for network optimization, such as cellular RAT information, cell identities, and signal quality metrics. By selectively collecting only the most relevant information rather than all possible parameters, the overhead is minimized while still enabling effective service optimization and handover management.

AI summary
Techniques are disclosed relating to a mobile device that communicates over short-range networks and long-range networks. In various embodiments, a mobile device includes one or more radios configured to communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. The mobile device may establish a first connection and a second connection with a network such that the first connection uses the short-range RAT and the second connection uses the cellular RAT. The mobile may collect information about the second connection and communicate the collected information to the network over the first connection. In some embodiments, the information includes a base station identifier, an MCC, an MNC, the cellular RAT and a cellular information age indicating the time since the information about the second connection was collected by the UE.
