Call Forwarding Authentication via Challenge Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bad actors exploit call forwarding services in IMS networks to gain unauthorized access to user accounts by tricking users into implementing communication forwarding requests, often using Man Machine Interface (MMI) codes, compromising multi-factor authentication.
Innovation Solution
Implementing a system where communication forwarding requests are confirmed by user authentication and fraud mitigation techniques, including challenge notifications and fraud detection modules, to ensure legitimate user intent before executing forwarding services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If call forwarding service is implemented without authentication, then ease of operation is improved, but security and reliability deteriorate due to unauthorized access
Solution Approach 1:
The system performs preliminary user authentication and sends challenge notifications before executing the call forwarding service. This preliminary action ensures that only authorized users can initiate forwarding, preventing unauthorized access while maintaining ease of operation for legitimate users.
Solution Approach 2:
The system provides feedback to the user through challenge notifications that ask for confirmation before executing the forwarding service. This feedback mechanism allows users to verify the legitimacy of the forwarding request, preventing fraud while maintaining user-friendly operation.
2Reliability
If fraud mitigation measures are added to call forwarding, then reliability is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary challenge notification mechanism between the call forwarding request and the actual service execution. This intermediary layer simplifies the overall system architecture by using a straightforward confirmation process rather than complex authentication protocols.
Solution Approach 2:
By performing authentication as a preliminary action before service execution, the system consolidates security measures into a single preparatory step rather than distributing complexity across multiple stages, thereby improving reliability without significantly increasing overall device complexity.
3Reliability
If user authentication is required for call forwarding, then security is improved, but ease of operation deteriorates due to additional verification steps
Solution Approach 1:
The challenge notification provides clear feedback to the user about what action is required, making the authentication process transparent and simple. Users can easily understand and respond to the verification request, maintaining ease of operation while ensuring security.
Solution Approach 2:
The system enables users to authenticate themselves through simple challenge notifications that require minimal input from the user. This self-service approach allows users to control their own authentication process without requiring complex procedures, maintaining ease of operation while improving security.

AI summary
Techniques are described herein for providing improved communication forwarding implementation for a user equipment. In embodiments, such techniques may be performed at least portion on one of an application server. Such techniques may comprise receiving, from a first user equipment, a request to implement a service in relation to the first user equipment, determining that the service relates to forwarding communications directed to the first user equipment to a second user equipment, providing, to the first user equipment, a notification including information about the service, receiving, from the first user equipment, a response to the notification, and making a determination about an implementation of the service based on the received response.
