Grace Period Mobile Network Access via Local Area Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prepaid wireless services often abruptly cut off users when their balance is depleted, disrupting communication and potentially harming user experience and retention.
Innovation Solution
Implementing a grace period that allows mobile communications devices to use available wireless local-area networks for voice calls and messaging even when the balance is insufficient, while disallowing mobile network access, and resetting when the balance is topped up.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prepaid services cut off access when balance is depleted, then service provider protects their resources, but user experience deteriorates and communication is disrupted
Solution Approach 1:
The patent segments communication access into two distinct pathways: mobile network access (requiring balance) and wireless local-area network access (available during grace period). This segmentation allows the system to provide different levels of service based on balance status, maintaining communication capability while protecting provider resources.
Solution Approach 2:
The system implements a grace period that begins in advance when balance is depleted, providing a transitional period before complete service termination. This preliminary action gives users time to understand their situation and replenish their balance without immediate disruption to essential communication.
2Device complexity
If all-or-nothing access control is used, then service provider simplifies management, but user retention suffers due to abrupt disconnection
Solution Approach 1:
The patent introduces dynamic access control that adapts based on balance status. The system automatically transitions between different access modes (full mobile network access when balanced, grace period mode when depleted, complete blockage after grace period expires). This dynamic behavior simplifies provider management while improving user retention through compassionate, progressive service termination.
3Quantity of substance
If mobile network access is completely blocked when balance is depleted, then service provider recovers resources, but essential communication is prohibited affecting livelihood
Solution Approach 1:
The patent introduces wireless local-area networks as an intermediary communication pathway during the grace period. This intermediary allows users to maintain essential communication through alternative means (WiFi, local networks) while the primary mobile network remains blocked, thus protecting provider resources while mitigating the harmful effects of complete communication disconnection.

AI summary
A mobile communications device receives an indication of a balance from a server when establishment of a voice call or sending of a message is requested. The mobile communications device determines whether the balance is sufficient to place the voice call or send the message over a mobile network. If the balance is sufficient to place the voice call or send the message over the mobile network, the voice call is established or the message is sent under normal operating conditions. If the balance is insufficient to place the voice call or send the message over the mobile network, a grace period is activated and the voice call is established or the message is sent during the grace period over an available wireless local-area network.
