Wireline Roaming Gateway Emulating Home Telecommunications Environment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireline telecommunications systems fail to provide users with the same environment and functionality when using a device or line other than their own, unlike wireless roaming, which limits functionality and phone number consistency when working remotely.
Innovation Solution
A method that emulates a user's home telecommunications environment by logically connecting any device to their associated network, using techniques like Intelligent Network or IP Multimedia Subsystem architectures to process signaling information and provide features such as dial tone, speed dials, and advanced call features, regardless of the physical location or device used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wireline telephone systems are used at remote locations, then users can access local telephone services, but users lose their personalized telecommunications environment and phone number consistency
Solution Approach 1:
The patent introduces a roaming gateway as an intermediary component that mediates between the remote wireline telephone and the home PBX system. This gateway translates and forwards signaling information between different network architectures, enabling the remote phone to access the home telecommunications environment without direct connection to the home PBX.
Solution Approach 2:
The patent creates a virtual copy of the home telecommunications environment by establishing a logical connection through the roaming gateway. The remote telephone is assigned a roaming number that replicates the home phone number's functionality, and the gateway copies the signaling information needed to recreate the home environment's features like speed dial and call forwarding.
2Loss of information
If call forwarding techniques are used to redirect incoming calls, then some phone number consistency is achieved, but the full telecommunications environment including features like speed dials and conference calling is not replicated
Solution Approach 1:
The patent segments the telecommunications system into distinct functional components: the roaming gateway handles signaling translation and forwarding, while the home PBX system maintains the core telecommunications environment. This segmentation allows the complex features to be preserved in the home system while the remote access mechanism remains relatively simple.
Solution Approach 2:
The roaming gateway acts as an intermediary that selectively forwards different types of signaling information between the remote telephone and home PBX. It translates various signal types (speed dial, conference calling, call forwarding) into the appropriate format for the home system, preserving full feature functionality without requiring complex changes to either end system.
3Adaptability or versatility
If wireless roaming is used, then users maintain their cellular phone number and full functionality while traveling, but the same physical device must be used throughout
Solution Approach 1:
The patent makes the wireline telephone universally compatible with multiple network environments by introducing the roaming gateway. The same physical wireline phone can now function both as a local telephone and as a remote access device to the home PBX system, providing multi-functionality that mirrors wireless roaming's device flexibility.
Solution Approach 2:
The roaming gateway ensures service consistency across different network architectures by mediating between the remote wireline telephone and the home PBX system. It translates and forwards signaling information reliably, ensuring that features like speed dial, conference calling, and call forwarding work consistently regardless of the physical location or device type.
4Ease of operation
If direct connection to home PBX is required for full functionality, then telecommunications environment consistency is achieved, but portability and remote access are lost
Solution Approach 1:
The roaming gateway serves as an intermediary that enables remote access without requiring direct connection to the home PBX. It handles the complexity of network translation and signaling forwarding, allowing the user to access the home telecommunications environment from any location with a wireline telephone while keeping the home PBX system unchanged.
Solution Approach 2:
The patent extracts the complexity of remote access implementation from the user side and concentrates it in the roaming gateway. The user simply needs to dial the roaming number to access the home environment, while the gateway handles all the complex signaling translation, forwarding, and feature replication in the background.

AI summary
The concept of “roaming” is extended to wireline networks with a network hosted technique which emulates a wireline telecommunications network user's environment when the user is using a wireline telecommunications device located at a physical location other than his or her “home” location, or when using a wireline or wireless telecommunications device other than his or her own regardless of the location. Any telephone or other telecommunications device being used by the user advantageously appears to be logically connected directly to his or her home telecommunications network, irrespective of the location of the telephone or other telecommunications device being used and the telecommunications network to which that device is actually connected.
