Server-Mediated Mobile Communication System for Roaming Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transnational enterprises, staff face challenges in contacting colleagues across different locations due to international roaming expenses and difficulties in obtaining or sharing phone numbers, leading to increased costs and communication breakdowns.
Innovation Solution
A mobile communication system comprising a mobile device and a server that exchanges device information via a mobile network, allowing the server to establish communication connections efficiently, reducing roaming expenses by using transition points or alternative networks for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If international roaming is used to contact staff across different locations, then communication can be established, but phone expenses increase due to roaming charges
Solution Approach 1:
The patent introduces a server as an intermediary that mediates communication between staff members at different locations. Instead of direct international roaming calls, the system uses the server to relay communications, allowing staff to contact each other through local networks or alternative communication channels that avoid expensive roaming charges while maintaining communication availability
Solution Approach 2:
The communication system is segmented into multiple components: mobile devices, a central server, and alternative communication networks. By dividing the communication path into segments that can use different networks (local networks, internet, etc.), the system avoids the need for expensive international roaming while maintaining communication capability
2Loss of energy
If staff travel to different locations and use local SIM cards, then roaming expenses are reduced, but contact information must be updated and shared manually
Solution Approach 1:
The system implements automatic feedback mechanisms where the server continuously receives location and contact information from mobile devices, updates the central database, and notifies relevant parties automatically. This eliminates manual information sharing while keeping contact information current
Solution Approach 2:
The system enables self-service automation where the server automatically manages contact information updates, location tracking, and communication routing without requiring manual intervention from staff members. When staff move to different locations, the system automatically updates their contact information and routing rules
3Productivity
If the system automatically tracks and updates device locations and communication methods, then communication efficiency improves, but device complexity and data processing requirements increase
Solution Approach 1:
The server acts as an intermediary that handles the complexity of tracking and managing communication methods, rather than requiring complex functionality in each mobile device. The devices remain relatively simple while the server performs the sophisticated location tracking and communication management
