Telephony Setup via Cellular IP Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IP telephony systems face delays in setting up communications with telephony devices, leading to potential premature termination of call attempts by the calling party due to the time-consuming process of registering the IP telephony software application.
Innovation Solution
The system employs a method where an incoming communication is initially established over a cellular-based communication path, and once the IP telephony software application is activated and registered, the communication is transitioned to an IP-based communication path, reducing setup time and preventing premature call termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IP telephony software application is activated and registered through push notification before receiving an incoming communication, then the communication can be routed to the correct device, but the setup time becomes significantly delayed
Solution Approach 1:
The system performs preliminary registration actions by having the telephony device register with the IP telephony system in advance before an incoming communication arrives. This ensures the device is ready to receive calls immediately without requiring last-minute push notifications that cause delays.
Solution Approach 2:
The patent introduces an intermediary mechanism where the telephony device maintains a persistent registered state with the IP telephony system, eliminating the need for real-time push notifications as intermediaries to trigger registration during call setup.
2Reliability
If the IP telephony software application must be actively running to maintain connection, then the system can route communications reliably, but the device requires continuous user activity to prevent disconnection
Solution Approach 1:
The telephony device automatically maintains its registration state with the IP telephony system without requiring continuous user intervention. The system self-manages the connection state, allowing the device to remain registered and ready for incoming communications even when the user is not actively using it.
Solution Approach 2:
The registration connection between the telephony device and IP telephony system is maintained continuously without interruption. This continuous state allows the system to route incoming communications immediately without requiring the user to reactivate the application or re-establish the connection.
3Adaptability or versatility
If the system uses push notification to trigger application launch, then the application can be activated remotely, but the process takes significant time causing premature call termination
Solution Approach 1:
The telephony device performs the registration action in advance before an incoming communication arrives, eliminating the need for time-consuming push notifications during call setup. The device is already registered and ready to receive calls immediately.

AI summary
When an incoming communication is directed to a telephony device that is capable of conducting an IP-based communication via an IP telephony system and a cellular-based communication via a mobile telephony service provider, the communication is initially setup as a cellular-based communication via the mobile telephony service provider. At the same time, an IP-based communication channel is setup between the telephony device and an IP telephony system. Once the IP-based communication channel is available, the communication is transitioned from the cellular-based communication channel to the IP-based communication channel.
