Residential Gateway Intercepts DECT Update Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating DECT devices through a residential gateway lack control over which servers are used for communication outside the DECT network, leading to potential security and reliability issues, and are not easily implementable at low cost.
Innovation Solution
A method where the gateway intercepts and analyzes requests from DECT devices to determine processing operations based on device identifiers and operator-provided configuration information, allowing for redirection to approved servers, enabling the gateway to control server selection and manage update requests effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gateway allows DECT devices to communicate with any server outside the DECT network, then the device can access update services freely, but security and reliability are compromised due to unapproved servers
Solution Approach 1:
The gateway acts as an intermediary between DECT devices and external servers. It intercepts HTTP requests from devices, analyzes them, and selectively redirects them to approved servers. This mediator role allows the system to maintain both accessibility to update services and security through controlled server selection.
Solution Approach 2:
The system implements feedback by monitoring device requests and dynamically responding with approved server addresses. The gateway receives update requests from devices, checks them against approved server lists, and provides feedback in the form of redirected requests to appropriate servers, ensuring continuous security validation.
2Reliability
If the gateway implements strict server approval and request interception mechanisms, then security and reliability are improved, but device complexity and implementation cost increase
Solution Approach 1:
The gateway performs self-service by maintaining local lists of approved servers and automatically making redirection decisions without requiring external intervention for each request. This self-contained approach simplifies the overall system architecture while maintaining security, as the gateway independently validates and routes requests.
Solution Approach 2:
The system performs preliminary action by pre-approving servers and storing them in the gateway before any device requests occur. This advance preparation allows the gateway to quickly validate requests against pre-established criteria, reducing real-time processing complexity while maintaining strict security controls.
3Reliability
If the gateway intercepts and redirects all HTTP requests, then server control is improved, but processing time and operational complexity increase
Solution Approach 1:
The gateway applies partial action by selectively intercepting only specific HTTP requests that require server approval, rather than processing every possible request. This targeted approach reduces unnecessary processing overhead while maintaining control over critical update operations, balancing security with efficiency.

AI summary
A method is provided for the remote management of a device connected to a residential gateway, including, when performed by the gateway: intercepting a request coming from the device including an address of a first server for which the request is intended, the purpose of the request being to obtain an address of a second server with which the device must be connected; determining a processing operation to be applied to the request, an identifier of the device contained in the request and configuration information obtained from an operator, the configuration information including information representing a set of devices, the plurality of processing operations including a processing operation applied when the device belongs to the set, including responding to the request without contributing the first server. When the processing to be applied is a redirection, a response is provided to the request containing the address of the second server.
