Host Resource Routing Shared Telephone Numbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for routing telephone calls over the Internet are complicated, expensive, and lack compatibility between different networks, making it difficult to establish cost-efficient connections between users on different service providers or with standard telephones.
Innovation Solution
A system that uses a host resource to route calls based on a unique combination of network identities and shared common telephone numbers, allowing users to be reached via a local number, with a database to manage entries and interface nodes connecting to packet-switched networks for efficient call setup and billing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a local telephone number is registered in each region/country where a user has contacts, then the user can be reached on a local call rate irrespective of the caller's location, but maintaining and administrating the local telephone numbers becomes relatively expensive for the callee
Solution Approach 1:
A single common telephone number is used universally across multiple regions and networks to reach the same user, eliminating the need for multiple local numbers. The host resource routes calls to different terminals based on the caller's network identity and the common number, providing universal access functionality.
Solution Approach 2:
The host resource acts as an intermediary between the common telephone number and the user's actual terminal. It receives calls to the common number, identifies the caller's network, and routes the call appropriately, thereby eliminating the need for the callee to maintain multiple local numbers while preserving local call rate benefits for callers.
2Loss of energy
If Internet-based telephone services are used, then long distance rates can be reduced significantly, but compatibility between different networks and standard telephones is lost
Solution Approach 1:
The system maintains compatibility with standard telephones and existing telephone networks while enabling Internet-based calling. The host resource interfaces with multiple home telephone networks and packet-switched networks, allowing standard terminals to use Internet routing without requiring specialized equipment or services.
Solution Approach 2:
The host resource and interface nodes act as intermediaries that translate between different network protocols and standards. This allows calls from standard telephones to be routed over the Internet while maintaining compatibility with existing telephone equipment and networks.
3Productivity
If double dialing or dial-through is employed, then calls can be routed through local access numbers, but it becomes complicated to store the callee's number in a conventional software telephone book
Solution Approach 1:
A single common telephone number serves multiple functions: it can be stored in conventional telephone books, it works across different networks, and it enables Internet-based routing. This eliminates the need for complex double dialing sequences and different notation standards for different networks.

AI summary
A telephone connection is established between a first terminal (A) and a second terminal (B). The first terminal (A) is presumed to be associated with a subscription in a first home telephone network (a) in which the terminal (A) is identified by means of a first network identity (CLI A ) . Correspondingly, the second terminal (B) is presumed to be associated with a subscription in a second home telephone network (ß) in which the second terminal (B) is identified by means of a second network identity (CLI B ) . According to the invention, a host resource (110) routes a call from the first terminal (A) to the second terminal (B) based on a combination of the first network identity (CLI A ) and a first common telephone number (# n ) in the first home telephone network () dialed by the first terminal (A). This is rendered possible because the first common telephone number (# an ) is selected such that the first is combination unique. However, the first common telephone number (# an) , as such, is adapted to be shared among a group of users in the first home telephone network.
