Cloud Modem Resource Allocation for SIM Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
International and domestic cross-regional roaming charges are expensive, and existing technologies face challenges in efficiently allocating cloud modems to SIM cards for optimal communication quality and cost-effective roaming, particularly when users travel abroad or across regions.
Innovation Solution
A cloud server-based resource allocation method that receives SIM card activation requests, obtains carrier information, selects a suitable cloud modem based on feature information such as signal quality, location, and network compatibility, and sends an indication message to enable the SIM card for communication through the target cloud modem, ensuring efficient allocation and utilization of cloud modem resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud modems are allocated to SIM cards for international roaming, then communication quality and roaming cost reduction are improved, but the complexity of resource allocation management increases
Solution Approach 1:
The system enables automatic matching between SIM cards and cloud modems based on carrier information and location data. The cloud server autonomously selects appropriate cloud modems without manual intervention, allowing the system to serve itself in resource allocation while maintaining high communication quality through intelligent matching algorithms
Solution Approach 2:
The patent utilizes dynamic parameter changes including location information, carrier details, and signal quality metrics to automatically select optimal cloud modems. By monitoring and responding to changes in these parameters, the system maintains reliable communication while simplifying management through automated decision-making based on real-time data
2Reliability
If cloud modems are selected based on signal quality and location, then communication quality is improved, but the time required for modem selection and allocation increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing relationships between carriers and compatible cloud modems, and by maintaining updated location and signal quality data in advance. When a SIM card needs allocation, the cloud server can quickly match it with suitable modems using pre-prepared information, reducing selection time while ensuring high signal quality through预先 established compatibility data
Solution Approach 2:
The patent replaces manual or sequential mechanical selection processes with automated electronic matching systems. The cloud server uses electronic databases and algorithms to instantly compare SIM card requirements with cloud modem capabilities, substituting time-consuming manual evaluation with rapid computational matching based on signal quality and location parameters
3Productivity
If automatic matching between SIM cards and cloud modems is implemented, then allocation efficiency is improved, but the complexity of the matching algorithm increases
Solution Approach 1:
The matching algorithm is segmented into distinct functional modules: carrier information extraction, location-based filtering, compatibility verification, and final selection. By dividing the complex matching process into separate manageable stages, the system achieves high allocation efficiency while keeping each individual module relatively simple and maintainable
Solution Approach 2:
The patent implements a universal matching framework that handles multiple types of SIM cards, carriers, and cloud modems through a single standardized algorithm. This multi-functional approach improves allocation efficiency across diverse scenarios while avoiding the need for separate complex algorithms for each specific case, as the universal system adapts to different situations through configurable parameters
