Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced voice services in wireless communications systems face limitations, including high costs for dedicated private networks, incompatibility with standard wireless networks, and drawbacks in Voice over IP solutions such as slower call setup and increased packet losses, necessitating a solution that complies with existing and emerging standards and provides superior user experiences with minimal handset upgrades.
Innovation Solution
A real-time exchange (RTX) interfaces with wireless communications systems to provide enhanced features like Voice Activated Floor Management, Voice Short Message Services, and Address Book Backup, leveraging call setup and in-band signaling within the network, and integrating with voice recognition systems and IP networks for efficient voice frame switching and presence applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated private network is installed to provide advanced voice services, then service reliability is improved, but system cost and device complexity increase significantly
Solution Approach 1:
The patent introduces an IP gateway as an intermediary component that bridges the existing public IP network and the wireless communication network. This gateway handles the complex protocol translations and signal routing, allowing advanced voice services to be provided without requiring a dedicated private network infrastructure. The gateway acts as a mediator that absorbs the system complexity while maintaining service reliability.
2Adaptability or versatility
If Voice over IP technology is used to provide advanced voice services, then adaptability to standard networks is improved, but call setup time increases and packet losses occur
Solution Approach 1:
The patent implements preliminary registration and call setup procedures where the IP gateway pre-establishes communication paths and validates network routes before actual voice transmission begins. The gateway performs advance signaling exchanges with both the public IP network and wireless network to prepare transmission channels, reducing the perceived call setup time for users while maintaining compatibility with standard networks.
3Ease of operation
If advanced voice services are implemented with minimal handset upgrades, then ease of operation is improved, but service functionality is limited
Solution Approach 1:
The patent combines multiple service functionalities into a unified IP gateway platform that handles voice messaging, conferencing, and other advanced services. Instead of requiring separate hardware additions to handsets, the gateway consolidates these functions in the network infrastructure, allowing users to access diverse services with minimal handset modifications while maintaining broad service functionality.
