Dynamic SIM Identity Assignment for Roaming Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems restrict users to specific service providers based on SIM cards, limiting service selection, increasing costs for roaming, and preventing dynamic bandwidth allocation, making it difficult for subscribers to access desired services like increased bandwidth and short message services according to actual requirements.
Innovation Solution
A service sharing system that includes a subscriber identity information database, a scheduling management system, and a service access device, which dynamically assigns appropriate subscriber identity information based on location and service type, allowing users to access international, any-network, any-service provider, any-technology, and any-service network access through a SIM-based system that simulates a physical SIM card for seamless service sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a physical SIM card is used to establish connection with service provider, then authentication and service access are enabled, but service selection is limited and roaming costs increase
Solution Approach 1:
The patent uses virtual SIM cards (eSIM) as digital copies of traditional physical SIM cards, stored in a database and dynamically assigned to user equipment. This eliminates the need for physical card changes while maintaining authentication functionality, thereby improving service selection flexibility without increasing device complexity.
Solution Approach 2:
The system implements a universal service access mechanism where a single user equipment can access multiple service providers through dynamically assigned virtual SIM cards. The scheduling management system enables one device to function with multiple identity credentials, allowing seamless switching between different service providers and networks based on location and service requirements.
2Ease of operation
If roaming service agreement is used for international access, then service availability is ensured, but service fees increase significantly
Solution Approach 1:
The system dynamically assigns virtual SIM cards based on real-time location information and service requirements. When a user travels internationally, the scheduling management system automatically detects the location and assigns a local virtual SIM card from the database, enabling access to local service providers at local rates rather than expensive roaming fees. This dynamic adaptation continues seamlessly as the user moves between countries.
Solution Approach 2:
The scheduling management system continuously receives feedback about user equipment location and service usage patterns. Based on this feedback, the system intelligently selects and assigns the most cost-effective virtual SIM card that matches the current geographic location and service requirements, optimizing both accessibility and cost efficiency.
3Reliability
If package broadband traffic is fixed by service provider, then service stability is maintained, but dynamic bandwidth acquisition is prevented
Solution Approach 1:
The system pre-provisions multiple virtual SIM cards with different service profiles, bandwidth allocations, and tariff plans in the database before they are needed. When a user requires dynamic bandwidth adjustment, the scheduling management system can immediately assign a pre-configured virtual SIM card with the appropriate service profile, enabling rapid service adjustment without compromising stability or requiring complex real-time negotiations with service providers.

AI summary
Disclosed is a service sharing system and apparatus. The system comprises: a subscriber identity information database (11), configured to store subscriber identity information of a subscriber whose service is to be shared; a scheduling management system (12), configured to select appropriate subscriber identity information from the subscriber identity information database (11) according to the location of a user equipment and the type of a service requested by the subscriber, and assign the selected subscriber identity information to the subscriber; and a service access device (13), configured to communicate with the scheduling management system (12) according to the assigned subscriber identity information, and communicate with a service provider system (14) corresponding to the assigned subscriber identity information to acquire the service requested by the subscriber. A subscriber acquires appropriate subscriber identity information as required and acquires an international, any-network, any-service provider, any-technology and mode, or any-service network access service.
