Dynamic Carrier Identity Switching via Memory Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication devices are limited in switching between different carrier networks, resulting in users experiencing different brands and customizations when traveling, as they cannot trigger a switch between carrier networks based on user preferences or location.
Innovation Solution
The mobile communication device is partitioned into system, user, and carrier sub-partitions, allowing multiple carrier identities to be stored and dynamically activated based on triggering events, such as location changes or user input, enabling seamless switching between carrier networks and maintaining user experience settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device stores only a single carrier identity in conventional memory, then the device structure remains simple and manufacturing cost is low, but the device cannot dynamically switch between different carrier networks when traveling internationally
Solution Approach 1:
The memory is segmented into multiple partitions: system partition, user partition, and carrier partition. The carrier partition is further divided into multiple carrier sub-partitions, each storing a different carrier identity. This segmentation allows the device to store and switch between multiple carrier identities while maintaining organized memory management and access control.
2Adaptability or versatility
If multiple carrier identities are stored in separate physical devices, then each carrier can be fully accessed, but the user cannot switch between carriers dynamically and must carry multiple devices
Solution Approach 1:
Multiple carrier identities that would traditionally require separate physical devices are merged into a single mobile device through multiple carrier sub-partitions in the memory. The system partition contains a carrier manager that enables dynamic switching between these merged carrier identities, allowing users to access multiple carriers without carrying multiple devices.
Solution Approach 2:
The system implements dynamic carrier identity switching based on triggering events such as location changes or user input. The carrier manager can dynamically activate different carrier sub-partitions, making the carrier configuration adaptable and changeable rather than static, thereby improving ease of operation.
3Ease of manufacture
If carrier partition has unrestricted write access, then carrier identities can be easily updated and modified, but system security and integrity are compromised
Solution Approach 1:
Different memory partitions are assigned different access control properties. The system partition has restricted write access protected by OEM access password for high security. The carrier partition has controlled write access protected by carrier access password, allowing carrier identities to be updated while maintaining security. This local differentiation of access rights balances ease of configuration with system reliability.

AI summary
A mobile communication device comprising a radio transceiver, wherein the memory is apportioned into a plurality of partitions, a first carrier identity stored in a first partition of the memory, wherein a carrier identity comprises a network access identity, a list of device capabilities, a list of application configurations and a specific user experience associated to the carrier identity. A second carrier identity stored in a second partition of the memory. An Application loaded on the device, that when executed by the processor, detects a triggering event and in response to the detection changes the active carrier identity of the mobile communication device to one of the carrier identities stored in the partitions of the memory and applies configurations associated with the carrier identity, where the mobile communication device conducts wireless communication via the radio transceiver based on the wireless communication network associated with the selected carrier identity.
