Standardized Signal Strength Indicator for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices lack a standardized method to accurately represent signal strength, as the traditional signal bars are inconsistent across manufacturers and service providers, failing to account for factors like RF interference, making it difficult to assess connectivity reliably.
Innovation Solution
Implementing a signal processor in user equipment to measure signal strength and user experience data, such as packet latency and throughput, to display standardized signal strength indicators, including sets of signal bars or dots, that vary based on specific user experiences like voice, video, and data, and can be consolidated for an overall experience representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional signal bars are used to display signal strength, then the display is simple and easy to understand, but the representation is inconsistent across manufacturers and service providers, lacking standardization
Solution Approach 1:
The patent applies parameter changes by transitioning from subjective, manufacturer-specific signal bar algorithms to objective, standardized measurements using RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) parameters. These standardized parameters enable consistent signal strength representation across different devices and service providers while maintaining the simple visual bar display format.
2Reliability
If signal bars indicate strong reception, then all five bars are displayed, but this fails to account for RF interference and other factors that may cause complete failure
Solution Approach 1:
The patent segments the signal assessment into multiple independent measurements including RSRP for signal strength, RSRQ for signal quality, and detection of RF interference conditions. Each measurement is evaluated separately and combined to provide a comprehensive reliability assessment, allowing the system to distinguish between strong signal with interference and actually reliable connectivity.
Solution Approach 2:
The patent introduces intermediary measurements (RSRQ and RF interference detection) that mediate between the raw signal strength (RSRP) and the final reliability determination. These intermediaries provide additional information about signal quality and interference conditions, enabling more accurate reliability assessment without requiring complex direct evaluation.
3Adaptability or versatility
If manufacturer-specific algorithms are used for signal bars, then each device can be optimized for its own performance, but there is no standard measurement for representing signal strength
Solution Approach 1:
The patent implements universality by adopting standardized 3GPP measurements (RSRP, RSRQ) that can be universally applied across all devices and service providers. These standardized measurements serve multiple functions: they provide consistent baseline data, enable cross-device comparison, and work across different network conditions, eliminating the need for manufacturer-specific algorithms while maintaining measurement accuracy.

AI summary
Techniques are described herein for presenting signal strength indicators on a display screen of a user equipment based on various telecommunications signals and one or more types of user experience corresponding to network performance metrics in a target geolocation of a network. The signal strength indicia can include one or more sets of signal bars. The user equipment can be equipped to measure the signal strength received. Additionally, the user equipment can analyze network performance metrics such as packet latency, throughput, packet loss, and availability based on user experience. One or more user experience types can be selected in order to compute a value that is representative of the received signal strength and the user experience data. Signal strength indicators are displayed on the display screen of the user equipment based on the measured signal strength and user experience for different forms of communication such as voice, video, and data.
