Cross-Platform Data Call Recovery via Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless systems fail to recover and continue wireless data communications or calls across different radio technology platforms, leading to permanent termination when a device loses connection and reconnects to a different technology platform, such as from WiFi to GSM/UMTS or vice versa.
Innovation Solution
The implementation of a 'Proprietary Internet Protocol Call-recovery Module' (PipCrM) and 'Proprietary VoIP Call-recovery System' (PVoipCrS) within wireless devices, which assigns a Unique Call Identifier (UCI) and automatically re-establishes data communication if the connection is lost within a pre-programmed time, ensuring seamless continuation of data calls across different wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless devices use standard hand-over mechanisms within the same radio technology, then data communication can be maintained within a single platform, but data calls cannot be recovered when switching between different radio technology platforms
Solution Approach 1:
The patent introduces a call recovery server as an intermediary component that mediates between wireless devices on different radio technology platforms. The server receives data call information from a first platform, stores it temporarily, and forwards it to a second platform when the device reconnects, enabling cross-platform call recovery without requiring direct compatibility between different radio technologies
Solution Approach 2:
The system performs preliminary actions by capturing and storing data call information (such as SIP messages, call parameters, and communication state) at the moment of disconnection on the first platform. This pre-preserved information is then used to reconstruct the data call on the second platform, ensuring continuity without requiring the device to maintain the same radio technology connection
2Ease of operation
If wireless devices automatically reconnect to available networks when connection is lost, then connectivity is maintained, but data calls are permanently terminated when switching between different radio technologies
Solution Approach 1:
The call recovery server implements feedback mechanisms by monitoring reconnection events from wireless devices. When a device reconnects to a second radio technology platform, the server receives feedback about the reconnection status and automatically triggers the forwarding of stored call information to the appropriate network elements on the second platform, ensuring data calls are recovered rather than terminated
Solution Approach 2:
The system discards the original data call connection on the first platform when disconnection occurs, but recovers the call by retrieving stored call information from the server and reconstructing it on the second platform. The server acts as a repository that preserves call state information across platform transitions
3Reliability
If wireless systems implement complex hand-over protocols to maintain data calls, then call continuity is improved within the same technology, but system complexity increases and cross-platform compatibility is not achieved
Solution Approach 1:
The patent segments the data call recovery function into a separate, dedicated component - the call recovery server - that operates independently from the wireless devices and network elements. This segmentation allows each component to handle only its specific function (capturing call info, storing it, forwarding it) rather than implementing complex integrated hand-over protocols across the entire system
Solution Approach 2:
The call recovery server serves as an intermediary that simplifies cross-platform communication by handling the complexity of information translation and forwarding between different radio technology platforms. This mediator approach reduces the complexity burden on individual devices and network elements while achieving reliable cross-platform call recovery
Data Source
AI summary
A method, system- or apparatus-adapted to facilitate the recovery and continuation of a data communication active across different wireless technology platforms. The end-users wireless device is adapted and authorized to operate on such different wireless technology platforms managed through a server. Loss of data communication of an adapted wireless device on one wireless-platform is dealt with by allowing reconnection onto a different wireless-platform thereby allowing recovery of the original data communication and a continuation of the same previously originated data call, provided the time between loss of data or loss of coverage and the reconnection to the same or different wireless technology platform by the adapted wireless device is less than the timeout permitted by the adapted wireless device or by the adapted server through which all data communications or data calls are handled through.
