Mobile Device Remote Unlock via Provisioning Server Payload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Telecommunication service providers face challenges when subscribers travel abroad, as locked mobile communication devices cannot connect to foreign networks, and unlocking them may lead to potential subsidy losses and network burden due to automatic reconnections with domestic servers.
Innovation Solution
A mobile communication device is unlocked using a payload that includes unlock instructions and monitoring software, which allows connection to approved networks while blocking unauthorized access and preventing reconnections to domestic servers when abroad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile communication device is unlocked to allow connection to foreign networks, then the device can be used abroad, but the service provider may lose subsidy payback potential and bear network burden from automatic reconnections
Solution Approach 1:
A provisioning server acts as an intermediary between the mobile device and service provider networks. It delivers a payload containing monitoring instructions that enable controlled unlocking - the device can connect to approved foreign networks while the server monitors and maintains subsidy protection, preventing direct unauthorized reconnections to domestic networks
Solution Approach 2:
The system implements feedback mechanisms where the provisioning server receives notifications when the device attempts to connect to non-approved networks. Based on this feedback, the server can revoke unlocking status or prevent automatic reconnections, thereby maintaining subsidy protection while allowing legitimate foreign network usage
2Adaptability or versatility
If the mobile communication device is unlocked, then it can connect to foreign radio access networks, but it may automatically reconnect to domestic servers creating network burden
Solution Approach 1:
The provisioning server serves as an intermediary that controls and monitors device-network connections. It provides instructions to block automatic reconnections to domestic servers while allowing connections to approved foreign networks, thereby eliminating the harmful network burden effect
Solution Approach 2:
The system applies preliminary anti-action by pre-configuring the device with instructions to block automatic reconnections to domestic networks before the device can generate the harmful effect. The provisioning server establishes control measures in advance that prevent the device from creating network burden through unauthorized reconnections

AI summary
A method of maintaining a lock state of a mobile communication device is disclosed. The method comprises a provisioning server receiving a request to unlock a mobile communication device. The method further comprises, in response to the request, the provisioning server provisioning the mobile communication device with a payload. The payload comprises unlock instructions to be executed, and a list of pre-approved telecommunications service providers. The payload further comprises instructions that lock the device if the mobile communication device attempts to activate or connect to a service provider that is not identified in the list of pre-approved service providers. The payload further comprises instructions to block attempts by applications installed on the mobile communication device to connect to a domestic network while the mobile communication device is communicatively coupled to a foreign network.
