Mobile Device Service Boundary Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems do not provide advanced warning to users or other parties when a mobile device is about to lose signal strength, leading to unexpected disconnections and inconvenience, especially when moving out of network coverage or into areas with weak signal strength.
Innovation Solution
A method implemented in mobile communications devices to predict crossing of service boundaries by using service coverage data and tracking data, issuing notifications to users about impending changes in signal strength or availability, allowing for timely completion of communications before disconnection.

Engineering Contradiction Analysis
1Reliability
If presence services indicate user availability based on reported status only, then the system is simple to implement, but it cannot provide advance warning of impending signal loss
Solution Approach 1:
The system performs preliminary actions by collecting signal strength data and determining service boundaries before the mobile device actually loses signal. The coverage service proactively identifies when a device is approaching a service boundary and notifies the presence service in advance, allowing the user's availability status to be updated before the disconnection occurs.
Solution Approach 2:
A coverage service is introduced as an intermediary between the mobile device and the presence service. This intermediary collects signal strength data, determines service boundaries, and provides advance notification to the presence service about impending signal loss, enabling more accurate availability indication without requiring complex changes to the presence service itself.
2Ease of operation
If the system provides advance warning of signal loss, then user experience is improved, but additional signal strength monitoring and boundary detection capabilities are required
Solution Approach 1:
The mobile device itself performs the signal strength monitoring and service boundary determination using its existing capabilities. The device collects signal strength data from the network and uses this data to determine when it is approaching a service boundary, then notifies the presence service. This self-service approach improves user experience without requiring additional external monitoring infrastructure.
Solution Approach 2:
The system implements feedback by continuously monitoring signal strength data and using this information to determine service boundaries and predict impending signal loss. The presence service receives feedback about the device's proximity to service boundaries and adjusts the availability status accordingly, providing users with advance warning while using existing monitoring capabilities.

AI summary
A method implemented at a mobile device for determining the availability of a mobile communications device on a network based on a prediction that the device will cross a peer-defined service boundary. The service boundary may be the periphery of a region in which the received signal strength is stronger than a minimum value, or the periphery of a region in which a particular service provider's signal is dominant. When the device is about to cross the service boundary, or has crossed the boundary, a notification of a change in service is issued to at least one of the user of the device, a presence service, or another network operator. The notification may comprise a change in the presence status of the mobile communications device. The service boundary is defined using aggregated data from a plurality of mobile communications devices reporting the received signal strength at various geographic locations.
