Enterprise Telephony Server Session Suspension During Power Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless telephony devices often experience abrupt communication session termination due to low or depleted power supplies, requiring users to re-establish connections, which is time-consuming and frustrating, especially when the reason for termination is unknown.
Innovation Solution
An enterprise telephony server system that detects a power supply issue in a wireless handheld device, temporarily holds the communication session, allows the device to be serviced, and then resumes the session once the power supply is restored, ensuring continuous communication without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the communication session is terminated when power supply needs servicing, then the device can be serviced without interruption, but the communication continuity is broken and user experience deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting power supply issues before they cause complete failure, notifying the user in advance, and preparing the communication session for suspension. This allows the user to service the power supply proactively rather than reactively, maintaining better communication continuity.
Solution Approach 2:
The system introduces an intermediary notification mechanism between the power supply status and the communication session. When power issues are detected, the system sends notifications to both devices and places calls on hold rather than immediately terminating sessions, acting as a mediator that manages the transition smoothly.
2Ease of repair
If the communication session is re-established after power servicing, then communication can resume, but time is lost and productivity decreases
Solution Approach 1:
The system performs preliminary actions by maintaining communication sessions in a held state rather than terminating them completely. This preserves the session context and routing information, so when power servicing is complete, the session can be quickly reactivated without full re-establishment procedures.
Solution Approach 2:
The system maintains the communication session in a held state throughout the power servicing process, preserving the useful action of communication readiness. The session remains active in the network infrastructure, just suspended at the device level, allowing for rapid resumption without breaking the communication flow.
3Reliability
If the communication session is placed on hold during power servicing, then communication continuity is maintained, but system complexity increases
Solution Approach 1:
The system uses the network infrastructure as an intermediary to manage held sessions. Rather than requiring complex local device logic to maintain session state, the network server handles session preservation and reactivation, simplifying device complexity while maintaining continuity.
Solution Approach 2:
The hold functionality leverages existing telephony network capabilities that already support call holding and resumption. By using established multi-functional network features rather than creating new proprietary mechanisms, the system maintains communication continuity without significantly increasing overall system complexity.
