Telecommunication Server Integrating Remote Devices Into Office Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call forwarding systems are cumbersome and inefficient, particularly for individuals with multiple communication devices, as they require manual reprogramming and lack seamless integration of enhanced services across different networks, leading to lost functionalities and increased costs due to unfavorable wireless communication rates.
Innovation Solution
A telecommunication system that integrates remote devices into a standard office telephone network, allowing selective establishment of communications with multiple devices and performing PBX functions, including call routing and priority preemption, using a server connected to both the public switched telephone network and wireless carriers, enabling seamless voice and data communication across various protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If call forwarding is used to route calls across multiple devices, then contact availability improves, but system complexity and operational difficulty increase
Solution Approach 1:
The patent introduces a server as an intermediary component that manages call routing between the corporate PBX and external wireless devices. This server acts as a mediator that handles the complexity of multi-device routing, eliminating the need for users to manually configure call forwarding on each device while maintaining contact availability across multiple devices.
Solution Approach 2:
The system provides universal call routing capabilities that work across different device types (office telephones, wireless telephones, PDAs, pagers) and different locations (office, hotel, remote sites). The server implements a unified routing mechanism that adapts to various devices and scenarios, allowing a single system to handle diverse communication needs without requiring device-specific configurations.
2Adaptability or versatility
If call forwarding is configured manually on each telephone, then routing flexibility improves, but ease of operation deteriorates
Solution Approach 1:
The system enables self-service call routing where the server automatically manages routing configurations based on pre-defined rules and user profiles. When a user registers their wireless device with the server, the system automatically establishes routing relationships without requiring manual configuration on each telephone device. The server handles routing decisions dynamically based on call context and user availability.
Solution Approach 2:
The system performs preliminary configuration actions by pre-registering user devices and establishing routing rules in advance. Users register their wireless devices with the server beforehand, and the server pre-configures routing relationships. When calls are placed, the routing is already established, eliminating the need for real-time manual configuration and improving ease of operation while maintaining routing flexibility.
3Adaptability or versatility
If calls are forwarded off the corporate PBX to wireless devices, then mobility improves, but loss of enhanced services occurs
Solution Approach 1:
The server acts as an intermediary that bridges the corporate PBX and external wireless networks, preserving enhanced services during call forwarding. When calls are routed to wireless devices, the server maintains connections to corporate resources such as voicemail, operator assist, and unified messaging systems. This allows users to access enhanced services regardless of whether they are calling from the office or mobile devices remotely.
Solution Approach 2:
The system implements nested call routing where external calls to wireless devices are nested within the corporate network infrastructure. The server embeds corporate PBX functionality within the external call path, allowing calls to be forwarded to wireless devices while still accessing corporate enhanced services. This nested architecture enables mobility while preserving access to voicemail, operator assist, and other corporate telecommunication resources.
4Reliability
If multiple telephones are involved in call forwarding, then contact reliability improves, but call duration on line increases
Solution Approach 1:
The system performs preliminary routing setup by pre-registering multiple contact devices and establishing routing rules in advance. When a call is placed to a user's primary number, the server has already configured alternative routing paths to secondary devices (wireless phones, PDAs, pagers). This eliminates the need for the calling party to remain on the line while multiple forwarding attempts are made sequentially, as the routing decision is made instantly based on pre-configured rules.
Solution Approach 2:
The system implements feedback mechanisms where the server monitors call outcomes and dynamically adjusts routing decisions. When a call is placed, the server attempts to route to the primary device and receives feedback on whether the call was answered. Based on this feedback, the server automatically routes to alternative devices without requiring the calling party to wait or manually initiate additional calls, thereby maintaining contact reliability while minimizing on-line duration.

AI summary
A telecommunication method, server and system that route an outbound telephone communication initiated by a wireless remote device through an enterprise communication network (the 1st leg of the call is conditionally established depending on the reception of a data signal indicating that the user has sufficient access rights to carry out the call). The system also routes an incoming call to a device associated with an enterprise communication network to a plurality of telephony devices including wireless devices and other remote devices.
