VoIP Call Transfer to Mobile Networks for Capacity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice over IP (VoIP) systems face capacity limitations in data networks, leading to service loss during peak usage periods due to predefined concurrent transmission limits, resulting in unnecessary capacity expenses and potential unavailability of service.
Innovation Solution
A method that automatically transfers excess voice transmission sessions to mobile communication devices or public switched telephone networks when the local data network reaches its capacity threshold, using a translation reference file to map VoIP numbers to mobile or PSTN numbers, thereby avoiding service loss and optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extra capacity is assigned to accommodate peak periods, then service availability during peak periods is improved, but bandwidth cost and network resource utilization worsen due to unused capacity for majority of time
Solution Approach 1:
The system dynamically adjusts network capacity allocation by implementing automatic call transfer between data network and mobile network based on real-time capacity conditions. During peak periods when data network capacity is exceeded, calls are automatically transferred to mobile network, and during low-utilization periods, calls remain on data network, optimizing resource utilization without requiring permanent extra capacity
Solution Approach 2:
The call transfer mechanism enables the mobile network to serve as an alternate pathway for voice transmissions, making the mobile network infrastructure universally usable for both mobile and fixed-line communications. This multi-functionality allows the system to utilize underutilized mobile network capacity during peak data network periods without requiring dedicated peak-capacity infrastructure
2Reliability
If extra capacity is assigned to accommodate peak periods, then service availability during peak periods is improved, but network resource utilization worsens due to underutilization for majority of time
Solution Approach 1:
The system implements dynamic capacity sharing between data network and mobile network through automatic call transfer. The call transfer decision is made in real-time based on current capacity utilization, ensuring that network resources are actively utilized during both peak and low-periods without waste
Solution Approach 2:
The system changes the operational parameter of call routing from static to dynamic by monitoring capacity utilization metrics and automatically transferring calls between networks based on threshold conditions, thereby optimizing resource utilization across varying demand conditions
3Reliability
If data network capacity threshold is enforced, then quality of service is maintained within capacity limits, but service loss occurs during peak usage periods when threshold is exceeded
Solution Approach 1:
The automatic call transfer mechanism acts as an intermediary between the data network and mobile network. When data network capacity threshold is exceeded, this intermediary automatically redirects calls to the mobile network, ensuring service continuity while maintaining quality of service standards through controlled transfer based on capacity conditions
Solution Approach 2:
The system establishes predetermined capacity thresholds and automatic transfer triggers in advance. When monitoring detects that capacity utilization is approaching or exceeding these pre-set thresholds, the system proactively transfers calls before service degradation occurs, cushioning against potential service loss

AI summary
Automatically transferring transmissions of a data network in which one or more processors receive metrics of active concurrent transmission sessions on a LAN that includes a data network, connected to a WAN, and a threshold level of concurrent transmission sessions of the data network of the LAN. Receiving a request for an additional transmission session, and responsive to determining that the threshold level of concurrent transmission sessions is exceeded, accessing data that maps a communication connection of the data network for a targeted recipient, to a communication connection of an alternate network corresponding to the targeted recipient, and performing a transfer of the additional transmission session from the communication connection of the data network for the targeted recipient, to the alternate network corresponding to the targeted recipient.
