Gateway Server Integrating Cellular Networks with Enterprise PBX
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprises lack control over cellular service costs, Quality of Service, and monitoring due to independent management by wireless carrier networks, which are not interconnected with enterprise voice and data networks.
Innovation Solution
A gateway server connects the public wireless voice and data network to enterprise networks, enabling effective call control and allowing enterprises to manage cellular service as if it were an extension of their PBX, with support for protocols like SIP and H.323, and routing functionality that bypasses traditional SS7 links for cost-effective and reliable signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If enterprises use public cellular carrier networks for employee communications, then cellular service coverage and accessibility are improved, but enterprises lose control over service costs, Quality of Service, and monitoring capabilities
Solution Approach 1:
The patent introduces an enterprise-controlled gateway server as an intermediary between the public cellular network and the enterprise network. This gateway acts as a mediator that enables enterprises to maintain control over cellular service costs, Quality of Service, and monitoring while still utilizing public cellular network coverage. The gateway intercepts and manages cellular traffic, allowing enterprises to enforce policies and track usage without requiring direct cellular network infrastructure.
2Ease of manufacture
If enterprises independently manage cellular service through carrier networks, then service delivery is simplified, but enterprises cannot integrate cellular networks with their existing voice and data networks
Solution Approach 1:
The patent merges the public cellular network with the enterprise voice and data networks through a gateway server. This integration allows cellular service to be combined with existing enterprise infrastructure, enabling unified communication capabilities. The gateway combines cellular traffic management with enterprise network protocols (SIP, H.323), allowing seamless integration of mobile and fixed communications while maintaining simplified service delivery through the carrier partnership.
3Ease of operation
If enterprises connect cellular network into their network using traditional methods, then call control integration is achieved, but cost-effective and reliable signaling is compromised due to dependency on SS7 links
Solution Approach 1:
The patent replaces the traditional SS7 (Signaling System No. 7) mechanical signaling links with IP-based signaling protocols. Instead of relying on proprietary SS7 infrastructure, the gateway uses standard IP networking with SIP and H.323 protocols to achieve call control integration. This substitution provides more reliable and cost-effective signaling by leveraging the enterprise's existing IP network infrastructure rather than depending on external SS7 links.
Data Source
AI summary
A method of operating a network server, such as a mobile application gateway, connect devices on a cellular or carrier network with individual networks, such as enterprise voice and data networks or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network, such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise.
