Virtual SIM Card Conflict Resolution via Dynamic Wait Periods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications, conflicts arise during the registration of virtual SIM cards due to multiple terminals sharing the same global virtual SIM card, leading to delayed service resumption and poor user experience.
Innovation Solution
A communication method that involves determining conflicts in global virtual SIM cards, updating conflict counts, and replacing the global virtual SIM card with a new one after a wait period determined by the conflict count and terminal identifier, to stagger reattempts and prevent simultaneous registrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple terminals use the same global virtual SIM card for registration, then resource sharing is improved, but registration conflicts increase
Solution Approach 1:
The patent segments the single global virtual SIM card resource by introducing wait periods and conflict counts for different terminals, effectively dividing the registration process into time-separated segments. This prevents simultaneous registration attempts while maintaining resource sharing capabilities.
Solution Approach 2:
The patent implements periodic action by introducing wait periods between registration attempts and using conflict counts to regulate registration timing. Terminals with higher conflict counts experience longer wait periods, creating a periodic registration pattern that reduces conflicts while allowing multiple terminals to eventually access the global virtual SIM card.
2Speed
If terminals immediately retry registration after conflict, then service resumption speed is improved, but registration conflicts worsen
Solution Approach 1:
The patent applies dynamics by making the wait period adaptive rather than fixed. The wait period dynamically adjusts based on the terminal's conflict count - terminals with more conflicts experience longer waits, while those with fewer conflicts have shorter waits. This dynamic adjustment balances service resumption speed with conflict reduction.
Solution Approach 2:
The patent changes the parameter of wait period duration based on the conflict count parameter. By modifying the wait period parameter dynamically according to conflict history, the system optimizes both service resumption speed and registration success rate, preventing immediate retries that would cause conflicts while avoiding excessive delays.
3Reliability
If wait period is extended to reduce conflicts, then registration success rate is improved, but service resumption time increases
Solution Approach 1:
The patent uses parameter changes to adjust the wait period based on the conflict count, ensuring that terminals with fewer conflicts experience shorter waits while maintaining high registration success rates. This dynamic parameter adjustment optimizes the balance between registration reliability and service resumption time.
Solution Approach 2:
The patent implements feedback through the conflict count mechanism, where registration outcomes feed back into determining future wait periods. Terminals receive feedback about their conflict status and adjust their retry timing accordingly, improving registration success rates while minimizing unnecessary delays for successful terminals.

AI summary
A method includes: establishing a connection with a virtual SIM card server in a first network using a global virtual SIM card of a terminal to acquire a regional virtual SIM card from the virtual SIM card server, wherein the regional virtual SIM card is configured to allow the terminal to access a second network; determining whether the global virtual SIM card of the terminal is in conflict; updating a count of conflicts in response to determining that the global virtual SIM card of the terminal is in conflict; and upon elapse of a wait period, replacing the global virtual SIM card of the terminal with a new one to acquire the regional virtual SIM card, wherein the wait period is determined according to the count of conflicts and an identifier of the terminal.
