Delayed Authentication After Radio Link Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio link failures in mobile devices disrupt communication sessions by requiring time-consuming authentication processes when attaching to new control components, potentially interrupting time-sensitive communications.
Innovation Solution
Delaying the authentication of mobile devices after a radio link failure until they are attached to a new control component, allowing for quick reconnection and prioritizing attachment based on communication session sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed before attaching the mobile device to the new control component, then security is ensured, but attachment time increases and communication sessions are interrupted
Solution Approach 1:
The patent applies preliminary action by performing authentication in advance during the initial attachment to the first control component. The mobile device is pre-authenticated before the radio link failure occurs, so that when it needs to attach to a second control component after failure, the authentication has already been completed or can be skipped, thereby reducing attachment time while maintaining security.
Solution Approach 2:
The patent inverts the traditional authentication sequence by delaying authentication until after attachment to the new control component. Instead of authenticating before attachment (traditional approach), the system attaches first and then performs authentication, which reduces attachment time and minimizes interruption to communication sessions while still ensuring security through subsequent authentication.
2Productivity
If authentication is performed quickly to minimize interruption, then communication session continuity is improved, but security verification may be compromised
Solution Approach 1:
The system performs authentication in advance during the initial connection to the first control component. This preliminary authentication ensures security verification is completed before the radio link failure occurs, so that when the device attaches to a new control component after failure, security has already been verified without requiring time-consuming re-authentication, thus maintaining both security and communication continuity.
3Reliability
If the mobile device is required to re-authenticate after radio link failure, then security is maintained, but the communication session is interrupted
Solution Approach 1:
Authentication is performed in advance during the initial attachment to the first control component, before the radio link failure occurs. This preliminary authentication ensures that when the mobile device needs to attach to a second control component after failure, the authentication has already been completed, allowing seamless attachment without interrupting the communication session, thus maintaining both security and session continuity.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining the authentication state across control component failures. The mobile device's authenticated status is preserved and recognized by the new control component, allowing the communication session to continue without interruption while still maintaining security through the pre-performed authentication.
Data Source
AI summary
Systems, methods, and computer-readable media for delaying authentication of a mobile device following a radio link failure, and thereby enabling the mobile device to quickly attach to a current control component associated with a network, are provided. The method includes receiving, at the current control component, a message indicating that the radio link failure occurred at a previous control component. Upon receiving the message, the mobile device is attached to the current control component. Authentication of the mobile device is delayed such that authentication of the mobile device is initiated subsequent to the attaching of the mobile device to the current control component. This delayed authentication ensures that a communication session in which the mobile device was engaged prior to the radio link failure is uninterrupted.
