Gateway Device SIP Selection for Shared VoLTE and VoIP Hardware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE gateways do not support simultaneous operation of VoLTE and VoIP modules, requiring separate slic chips for each function, leading to increased cost and hardware complexity.
Innovation Solution
A gateway device with integrated cellular and IP network SIP client modules that can select between them based on status and priority, allowing shared use of a single set of slic chips for VoLTE and VoIP functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate slic chips are used for VoLTE and VoIP functions, then both voice call services can be supported, but the gateway cost increases
Solution Approach 1:
The patent merges the VoLTE module and VoIP module into a single integrated gateway device, allowing both voice call services to be supported simultaneously using shared hardware resources including a common slic chip, thereby reducing gateway cost while maintaining functional versatility
Solution Approach 2:
The gateway device is designed with universal hardware components that can perform multiple functions - the same slic chip and voice interface can handle both VoLTE and VoIP protocols through software configuration, eliminating the need for separate dedicated hardware for each function
2Adaptability or versatility
If a hardware switch module is added to switch the slic chip between VoLTE and VoIP modules, then both functions can be supported, but the gateway cost increases
Solution Approach 1:
The patent eliminates the hardware switch module by merging the control functions into software. The gateway controller dynamically allocates the shared slic chip to either VoLTE or VoIP module through software-based resource management, removing the need for additional hardware switching components
3Productivity
If two sets of slic chips are used in a penaltized board device, then VoLTE and VoIP modules can operate simultaneously, but the gateway cost increases
Solution Approach 1:
The patent implements dynamic resource allocation where the single slic chip can be dynamically assigned to different modules based on real-time call requirements. The gateway controller monitors and manages the allocation, allowing the hardware to adapt its function dynamically without requiring duplicate components
Solution Approach 2:
The gateway controller periodically monitors the operational status and resource utilization of the VoLTE and VoIP modules, dynamically reassigning the shared slic chip between modules based on periodic scheduling and real-time demand, enabling simultaneous support without permanent duplication of hardware
