Wireless Device Proxy Information Reporting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional proxy information reporting in wireless communication systems is ineffective for various types of cells, particularly leading to excessive and frequent reporting, especially in densely deployed pico cells, where entering or leaving proximities may not be accurately reported due to high cell density.
Innovation Solution
A method and apparatus for reporting proxy information where a wireless device reports first proxy information upon entering a target cell's proximity and second proxy information upon leaving, with the option to suspend reporting using a timer or restricted lists to prevent excessive transmission, thereby reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If proxy information is reported frequently to accurately track cell proximity changes in densely deployed small cells, then measurement precision is improved, but signaling overhead increases
Solution Approach 1:
The patent implements periodic action by introducing suspension timers that control when proxy information reporting occurs. Instead of continuous reporting, the system uses timer-based periodic reporting where the wireless device suspends reporting during the timer period and only reports when the timer expires or certain conditions are met. This reduces the frequency of reporting while maintaining necessary monitoring capability.
Solution Approach 2:
The patent applies partial action by implementing restricted lists that selectively enable or disable reporting for specific cells or frequencies. The network can configure the wireless device to report only for certain target cells or frequencies, rather than requiring comprehensive reporting for all cells. This partial reporting approach reduces overall signaling overhead while maintaining accuracy for critical cells.
2Quantity of substance
If proxy information reporting is restricted using timers and prohibited lists to reduce signaling overhead, then signaling overhead is decreased, but reporting frequency may be insufficient to track rapid cell changes
Solution Approach 1:
The patent implements dynamics by making the reporting behavior adaptive rather than static. The suspension timer can be configured with different values for different cells or frequencies, and the reporting behavior dynamically adjusts based on current conditions. The system can transition between reporting and suspension states based on timer expiration and event triggers, creating a dynamic reporting mechanism that balances overhead reduction with maintaining adequate reporting frequency.
Solution Approach 2:
The patent uses feedback mechanisms where the network receives proxy information reports and can respond by adjusting suspension timer values or modifying restricted lists. This feedback loop allows the system to learn from reporting patterns and optimize the balance between signaling overhead and reporting frequency. The network can increase reporting frequency for cells showing rapid changes by adjusting timer parameters based on observed behavior.

AI summary
Provided are a method and a wireless device for reporting proxy information in a wireless communication system. As the wireless device enters the proximity of a first target cell on a target frequency, the wireless device reports first proxy information indicating entering the proximity to a serving cell. Before the wireless device transmits proxy information indicating leaving the proximity after reporting the first proxy information, the wireless device does not report proxy information on entering the proximity of any other target cell on the target frequency.
