SMS-Based Secondary Endpoint Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems require users to manually enter network identifiers and validate credentials to add secondary endpoints, which is cumbersome, especially for devices with small screens or limited text entry capabilities.
Innovation Solution
A method where users can add additional endpoints by replying to an SMS message, reducing the need to manually enter network identifiers or validate credentials, using a sequence of messages between primary and secondary devices and the services network to authorize the additional endpoint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually enter network identifiers and validate credentials to add secondary endpoints, then the system can securely authorize additional devices, but the operation becomes cumbersome and complex
Solution Approach 1:
The system performs authorization automatically without requiring manual user input. When a secondary device requests to join the network, the network device automatically sends an SMS message to the primary device's phone number, and the primary device automatically replies with authorization credentials, eliminating the need for users to manually enter network identifiers or validate credentials on secondary devices
Solution Approach 2:
The patent introduces an intermediary SMS messaging system that facilitates authorization between primary and secondary devices. Instead of direct manual configuration, the network device uses SMS messages as an intermediary channel to transmit authorization information, simplifying the user interface while maintaining security
2Adaptability or versatility
If the interface requires extensive text entry for adding endpoints, then complete configuration information can be provided, but devices with small screens or limited text entry capabilities cannot be used
Solution Approach 1:
The patent extracts the essential authorization function from the complex manual configuration process. Instead of requiring users to input multiple network identifiers and credentials, the system extracts only the necessary authorization action and implements it through automatic SMS-based authentication, eliminating unnecessary interface complexity
Solution Approach 2:
The patent replaces the mechanical manual text-entry system with an automated SMS-based communication system. The physical act of typing network identifiers is substituted by automatic message transmission and processing, enabling devices with limited text input capabilities to perform complete endpoint configuration

AI summary
A method for adding an additional endpoint for a service based on a short messaging service (SMS) message may include receiving a request to add a second user equipment (UE) as an additional endpoint for a service associated with a first UE, and generating a transaction identifier in response to receiving the request. The method may include sending a command to provide a short message service (SMS) message to the first UE requesting permission to add the second UE as the additional endpoint, and receiving a message granting permission to add the second UE as the additional endpoint, where the message may include a network identifier assigned to the first UE. The method may include generating credential(s) for authorizing the second UE to access the service, and may then provide the credential(s) to the second UE.
