Virtual SIM Conflict Handling for Staggered Network Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications, virtual SIM cards face conflicts when multiple terminals attempt to register using the same global SIM card simultaneously, leading to network failures and prolonged service disruptions.
Innovation Solution
A communication method that randomly distributes reattempts to acquire regional SIM cards among terminals, using staggered wait periods based on conflict counts and identifiers to reduce simultaneous registrations and resolve conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple terminals use the same global virtual SIM card for registration, then the global virtual SIM card can serve multiple terminals, but simultaneous registration attempts cause conflicts and service disruptions
Solution Approach 1:
The patent implements periodic action by introducing staggered wait periods between registration attempts. When a terminal detects conflict (failed registration), it waits for a random duration before retrying, spreading out simultaneous registration attempts over time. This periodic retry mechanism with random intervals resolves the contradiction by maintaining multi-terminal support while preventing simultaneous conflicts.
2Speed
If terminals immediately retry registration after failure, then service resumption is fast, but simultaneous retries exacerbate conflicts and prolong disruptions
Solution Approach 1:
The patent applies dynamics by making the wait period variable rather than fixed. Terminals calculate dynamic wait durations based on conflict detection results and random factors, adjusting their retry timing adaptively. This dynamic approach balances fast service resumption with conflict avoidance, as terminals neither immediately retry (causing conflicts) nor wait too long (slowing resumption).

AI summary
Embodiments of the present disclosure provide a communication method, a communication apparatus, a terminal, and a computer-readable storage medium. The 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. In this way, a delay of service resumption is shortened, and user experience is enhanced.
