Gateway Trust Sessions for Multi-Device Service Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in first responder environments face inefficiencies due to high bandwidth and processing resource usage from frequent token requests and refresh cycles, leading to potential system failures and reduced performance when handling multiple communication devices.
Innovation Solution
A gateway device establishes a trust session with an application server, providing service requests on behalf of communication devices, using signed payloads and indicators, thereby reducing the need for direct token exchanges between the application server and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct token exchange between communication devices and application server is used, then authentication and authorization can be performed, but bandwidth and processing resources are excessively consumed
Solution Approach 1:
The patent introduces a gateway device as an intermediary between communication devices and the application server. The gateway establishes a trust session with the application server and performs token exchange on behalf of multiple communication devices. This mediator approach consolidates numerous individual token requests into fewer gateway-level requests, significantly reducing bandwidth consumption while maintaining authentication reliability.
2Reliability
If frequent token refresh cycles are implemented, then authentication tokens remain valid, but processing resources and bandwidth are heavily utilized
Solution Approach 1:
The patent merges multiple communication devices into a single group managed by one gateway device. Token refresh operations are performed at the gateway level rather than individually for each device. This consolidation reduces the total number of token refresh cycles from hundreds (if each device refreshed individually) to a manageable number, preserving token validity while maintaining system performance.
3Adaptability or versatility
If multiple communication devices connect directly to the application server, then each device can be individually authenticated, but the system does not scale well
Solution Approach 1:
The patent segments the system architecture into two layers: gateway devices that manage groups of communication devices, and the application server that interacts with gateways rather than individual devices. This segmentation allows the system to scale by adding gateway devices that each handle multiple communication devices, reducing the complexity of direct one-to-many connections while maintaining individual device connectivity and authentication capabilities.

AI summary
A device, system and method for providing services between a communication device and an application server is provided. A trust session is established between a gateway device and an application server. The gateway device provides, to the application server, on behalf of a communication device served by the gateway device: a service request that requests a service from the application server; an indication of successful authentication of the gateway device by the application server, the indication associated with the trust session; and a payload including an indicator of the communication device. The gateway device receives, from the application server, a verification of the service request determined using at least the indication associated with the trust session. The service is provided between the communication device and the application server via one or more of the gateway device and a network.
