Enterprise Call Routing via Intermediary Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprises face challenges in managing and controlling wireless voice calls made from mobile devices on public land mobile networks, as existing systems lack the ability to enforce usage restrictions and monitor calls for business purposes.
Innovation Solution
A method and system that route calls from enterprise-associated mobile devices through an enterprise communications system, preventing direct wireless voice calls and bridging calls between the mobile device and the remote party via a public land mobile network, using an enterprise voice application server and private branch exchange to manage and monitor calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct wireless voice calls are allowed on PLMN, then mobile device usability is improved, but enterprise call management control deteriorates
Solution Approach 1:
The patent introduces an enterprise communications system as an intermediary between the mobile device and the PLMN network. This mediator intercepts and manages call signaling, allowing direct wireless calls to function while maintaining enterprise policy control. The intermediary enables both mobile usability and enterprise management by acting as a controlling gateway.
2Device complexity
If enterprise communications system intercepts calls, then call management control is improved, but call setup time deteriorates
Solution Approach 1:
The enterprise communications system performs preliminary actions by pre-authenticating mobile devices and pre-configuring call routing policies before actual calls occur. Call management rules and enterprise policies are established in advance, allowing the intercept mechanism to quickly enforce decisions without delaying call setup during actual usage.
3Reliability
If all calls are routed through enterprise system, then usage policy enforcement is improved, but system complexity deteriorates
Solution Approach 1:
The patent extracts the call management and policy enforcement functions from the mobile device itself and places them in the enterprise communications system. The mobile device is simplified to only handle basic call initiation, while the complex policy decision-making and routing control are separated out to the enterprise system, reducing device complexity while maintaining enforcement reliability.

AI summary
Methods, systems, and mobile devices for managing mobile calls to or from an enterprise-associated mobile device. The system and mobile device are configured to ensure all calls over a public land mobile network are routed through an enterprise communications system. The mobile device is prevented from directly calling remote parties through the public land mobile network and the public land mobile network forwards all calls addressed to the mobile device to the enterprise communications system. The enterprise communication system responds to a request to connect the mobile device and the remote party by establishing a first call with the mobile device, establishing a second call with the remote party, and bridging the two calls to connect the mobile device to the remote party.
