Enterprise Cellular Gateway for Call Control and Cost Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprises lack control over cellular service costs, Quality of Service, and monitoring capabilities due to independent management by wireless carrier networks, which are not interconnected with enterprise voice and data networks.
Innovation Solution
A mobile application gateway connects the cellular network to enterprise networks, enabling enterprises to manage cellular voice and data services through a gateway server that supports IMS network architecture, allowing for call control and data session management, and eliminating the need for VPN software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular service is independently managed by wireless carrier networks, then cellular service can be provided without enterprise network integration, but enterprises cannot control cellular service costs, Quality of Service, or monitoring
Solution Approach 1:
The patent introduces a gateway server as an intermediary component that connects the cellular network to the enterprise network. This gateway server receives call setup messages from the cellular network's mobile switching center, processes them through enterprise network components (PBX, policy servers), and enables enterprise control over cellular service routing, costing, and monitoring without requiring direct enterprise management of the cellular infrastructure
2Ease of operation
If enterprises integrate cellular network with enterprise voice and data networks through a gateway server, then enterprises can control and monitor cellular services, but network complexity increases
Solution Approach 1:
The patent segments the integration functionality into distinct modular components: a gateway server for message interception and translation, a PBX for call routing, policy servers for cost management, and logging systems for monitoring. This segmentation allows each component to perform a specific function independently, making the overall complex system manageable through clear separation of concerns and standardized interfaces
3Ease of operation
If call control is transferred from cellular network to enterprise network, then enterprises can manage call routing and costs, but the cellular network's autonomous call handling capability is reduced
Solution Approach 1:
The patent implements preliminary action by having the gateway server intercept and process call setup messages before they reach the cellular network's mobile switching center. The gateway server pre-establishes enterprise network resources (routing paths, cost accounting records, monitoring configurations) in advance, so that when calls are routed through the enterprise network, control is already in place without compromising the cellular network's ability to handle calls autonomously through the gateway interface
Data Source
AI summary
A method for handling call originations is provided. The method includes sending origination information from a mobile device to an application server in an enterprise network using Short Message Service (SMS) and determining whether a hotline feature is present in a subscriber profile associated with the mobile device. Data is then routed from the mobile device to a predetermined destination based on the hotline feature.
