Automated credential porting for mobile devices

What is this patent about?

’510 is related to the field of wireless service management and automated device provisioning. Specifically, it addresses the technical challenges associated with porting portable credentials, such as phone numbers, between different mobile devices or service providers. The background context involves the often cumbersome and manual process required to update a device's internal identity when a user switches carriers or hardware while attempting to maintain their existing mobile identity.

The underlying idea behind ’510 is to eliminate manual user intervention during the final stages of a credential port by enabling the mobile device to autonomously detect when its current network credentials have become invalid and proactively seek out new ones. By pre-storing a target credential (the desired final state) and monitoring for a network-provisioning state change—such as a failed authentication or denied service—the device can recognize the transition period and automatically bridge the gap between the old service state and the new one.

The claims of ’510 focus on a wireless device and computer-readable media configured to manage the replacement of a particular credential with a target credential. The claimed mechanism involves obtaining a user request for the change, detecting a change in the network-provisioning state, and then automatically triggering a programming session with a network element. This session is specifically initiated after the device determines a mismatch between its active credential and the intended target credential, resulting in the retrieval and storage of an updated credential.

In practice, the invention works by utilizing a device agent that acts as an intelligent intermediary between the user interface and the network's provisioning servers. When a user initiates a number transfer, the device doesn't just wait for the network to push an update; it stores the expected outcome locally. Once the old carrier releases the number and the current credentials fail to authenticate, the device enters a bootstrap state or utilizes an ambient, zero-rated data channel to contact a programming server. This ensures the device remains functional and reaches its final configured state even if the primary cellular service is temporarily suspended during the porting window.

This approach differs from prior solutions that typically required users to manually enter activation codes, call customer support, or perform specific dialer sequences to force a device into a programming mode. Unlike traditional methods where the device is a passive recipient of Over-the-Air (OTA) updates, this system makes the device an active participant that monitors its own authorization status. By comparing the live credential against a locally stored 'expected' version, the device can self-correct and complete the provisioning process in the background, significantly reducing the likelihood of the device becoming a 'brick' during carrier transitions.
