Solution Overview
Problem
Current mobile phone technologies restrict voice calling minutes and incur significant roaming charges, while users lack seamless communication between public-switched telephone networks and packet-switched data networks, especially for international users accessing the internet via Wi-Fi.
Innovation Solution
A telecommunications switch that connects to both public-switched telephone networks (PSTN) and packet-switched networks, dynamically routes calls based on bandwidth availability, using a processor to determine the best network for call transmission, allowing calls to be sent via packet-switched networks when bandwidth is sufficient and switching to PSTN when insufficient, and implementing a billing mechanism to charge based on call duration on PSTN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calls are routed via PSTN to ensure reliable voice calling, then call quality and reliability are maintained, but voice calling minutes are restricted and roaming charges increase
Solution Approach 1:
The system dynamically selects between PSTN and packet-switched networks based on real-time conditions. The telecommunications switch monitors network status and automatically routes calls through the most appropriate network type, transitioning from static routing to dynamic adaptive routing to reduce charges while maintaining quality.
Solution Approach 2:
The invention changes the routing parameter from fixed PSTN routing to variable routing that considers packet-switched network availability. By monitoring bandwidth and network conditions, the system adjusts the routing decision parameter to select optimal paths, transforming call routing from a static to a parameter-driven dynamic process.
2Object-affected harmful factors
If calls are routed via packet-switched network to reduce charges, then roaming charges and voice calling restrictions are reduced, but network bandwidth may be insufficient to handle the call
Solution Approach 1:
The telecommunications switch performs preliminary bandwidth assessment before routing calls through the packet-switched network. By checking network capacity in advance and only selecting packet-switched routing when sufficient bandwidth is available, the system prevents call quality degradation while still achieving cost reduction when conditions permit.
Solution Approach 2:
The invention introduces a voicemail system as an intermediary component that facilitates network conversion. The voicemail acts as a mediator between PSTN and packet-switched networks, enabling seamless call transfer and protocol conversion to allow calls to traverse different network types appropriately.
3Adaptability or versatility
If seamless communication between PSTN and packet-switched networks is implemented, then communication versatility is improved, but system complexity increases
Solution Approach 1:
The telecommunications switch is designed with multi-functionality to handle both PSTN and packet-switched network protocols simultaneously. By integrating multiple network interface capabilities and routing logic within a single switch platform, the system achieves universal network compatibility without requiring separate dedicated systems for each network type.

AI summary
In embodiments of the disclosed technology, devices and methods for redirecting a telephone call from a public-switched telephone to a packet-switched data network. The phone call is initially received via the public-switched telephone network having a dialed number associated with a hand-held wireless device of a called party. Upon initialization of the phone call, a route is determined from the telecommunications switch to the hand-held wireless device of the called party via a packet-switched network. The bandwidth of the packet-switched network is then detected to determine the ability of the network to handle the call. If the packet-switched network is determined to be capable of handling the call, the call is forwarded over the packet-switched data, thereby reducing or eliminating charges for wireless minutes.
