Dynamic IMEI Reassignment in Multi-SIM Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in providing dynamic international mobile equipment identifier (IMEI) re-assignment in multi-subscriber identity module (SIM) electronic devices, leading to service registration failures and device locking issues when carrier-specific IMEI dependencies are not met.
Innovation Solution
A method and system that dynamically re-assigns IMEIs in a multi-SIM electronic device by monitoring service registration statuses and providing a second set of IMEI assignments different from the initial set in response to service registration failures, without relying on stored carrier-specific configuration rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic mapping of IMEIs to SIMs is implemented, then service registration flexibility is improved, but carrier compatibility deteriorates when IMEI expectations are not met
Solution Approach 1:
The system monitors service registration responses from the network and uses this feedback to dynamically adjust IMEI assignments. When a service registration fails, the system detects the failure response and re-assigns a different IMEI to the affected SIM, creating a closed-loop control system that adapts to network requirements while maintaining compatibility
Solution Approach 2:
The patent implements dynamic IMEI assignment where the mapping between IMEIs and SIMs is not fixed but can change in response to network conditions. The system transitions from static carrier policy-based assignment to dynamic assignment based on real-time service registration outcomes, allowing the device to adapt its IMEI presentation to match carrier expectations
2Device complexity
If fixed mapping of IMEIs to SIMs is used, then device simplicity is improved, but service registration success deteriorates when carrier expectations are not met
Solution Approach 1:
The device performs self-diagnosis and self-correction by monitoring its own service registration status and automatically re-assigning IMEIs when failures occur. The system serves itself by detecting registration failures and adjusting its own IMEI assignments without external intervention, maintaining both simplicity and reliability
3Reliability
If carrier-specific configuration rules are stored, then initial service registration is improved, but adaptability to rule changes deteriorates
Solution Approach 1:
The system performs preliminary service registration attempts with initial IMEI assignments and uses the results of these preliminary actions to guide subsequent IMEI selections. By learning from initial registration outcomes and continuously adapting based on feedback, the system prepares for and adapts to carrier rule changes without requiring pre-stored configuration data

AI summary
A method includes providing, by at least one processing device, a first set of assignments of international mobile equipment identifiers (IMEIs) to a plurality of subscriber identity modules (SIMs) associated with an electronic device. The method also includes monitoring, by the at least one processing device, each of a plurality of service registration statuses associated with the SIMs for a service registration failure. The method further includes, in response to at least one service registration failure being detected, providing, by the at least one processing device, a second set of assignments of IMEIs to the SIMs. The second set of assignments is different from the first set of assignments.
