Telecommunication Service Platform for Virtual Call Number Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunications systems do not efficiently enable the use of multiple call numbers across different phones and access technologies without requiring additional software on subscriber terminals, limiting scalability and flexibility.
Innovation Solution
A telecommunications system that utilizes a service platform and database to manage and process virtual call numbers centrally, allowing subscribers to use multiple call numbers without modifying their terminals, and scales by adding virtual and real call numbers without installing additional application software on subscriber terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual call numbers are managed centrally via service platform, then scalability is improved, but system complexity increases
Solution Approach 1:
A service platform is introduced as an intermediary component between subscriber terminals and the telecommunications network. This platform centrally manages virtual call numbers, routing tables, and number portability information, enabling scalable addition of virtual numbers without modifying subscriber terminals while distributing the complexity management function.
Solution Approach 2:
The system segments the call routing function by separating subscriber-specific virtual number management from the core network. The service platform handles virtual number mapping and routing decisions, while the telecommunications network processes only the actual call signaling, dividing system complexity into manageable segments.
2Ease of operation
If multiple call numbers are supported without additional software on terminals, then ease of operation is improved, but device functionality is reduced
Solution Approach 1:
The service platform provides universal functionality for multiple call number types (real numbers, virtual numbers, portability numbers) through a single centralized system. Subscriber terminals maintain their original functionality while the platform adds multi-number capability, avoiding the need for terminal software modifications.
3Object-affected harmful factors
If real call numbers are hidden to protect user privacy, then user privacy is improved, but information availability decreases
Solution Approach 1:
The service platform extracts and stores real call number information separately from the call routing process. Virtual call numbers can be displayed to callers while the platform maintains the mapping to real numbers for privacy protection, allowing information to be extracted and managed independently.
Solution Approach 2:
The system provides feedback mechanisms where the service platform can disclose real call numbers to network elements when necessary for call routing, while maintaining the ability to hide them from end users. This selective information disclosure balances privacy requirements with operational needs.

AI summary
A method and a telecommunications system (10) is provided which enables to establish a call via at least one telecommunications network (30, 40) using a service platform (60) interconnected to the at least one telecommunications network (30, 40), wherein a real call number and at least one virtual call number are allocated to each of a plurality of telephone subscribers. The virtual call numbers are stored and processed on the service platform (60, 70), but not in the terminals (50, 90) of the telephone subscribers.
