IP Network Device Holding Registration Messages for VoIP Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In VoIP communication systems, network switching during connection interruptions is often slow due to the lack of immediate re-authentication mechanisms, leading to prolonged disruptions, as the end device waits for the predefined re-authorization period, and sensitive credentials cannot be accessed by IP network devices for security reasons.
Innovation Solution
The IP network device holds registration messages containing credential information during normal registration processes, allowing it to promptly re-authorize the end device during network switching events, reducing the re-authorization time from minutes to seconds without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the end device waits for the predefined re-authorization period, then security credentials are protected, but the re-authorization time is prolonged leading to slow network switching
Solution Approach 1:
The IP network device performs preliminary action by holding the registration message received during normal operation, preparing it in advance for use during network switching. This allows the credential information to be immediately available when switching occurs, eliminating the need to wait for the predefined re-authorization period while maintaining security.
2Productivity
If the IP network device accesses credential information, then re-authorization can be performed quickly, but security credentials are exposed
Solution Approach 1:
The IP network device acts as an intermediary that temporarily holds the registration message containing encrypted credential information. The device does not decrypt or permanently store the credentials but uses the held message to facilitate quick re-authorization during network switching, thus achieving speed without compromising security.
3Reliability
If the device switches to alternative pathway during connection failure, then communication continuity is maintained, but the transition is slow causing disruption
Solution Approach 1:
The IP network device prepares the registration message in advance during normal operation and holds it ready. When network failure occurs, the device can immediately use the held message to authenticate and switch to the alternative pathway, significantly reducing switching time and maintaining communication continuity without disruption.

AI summary
Devices, methods, systems, and computer-readable media for holding registration messages during communication session switching are described herein. One or more embodiments include a processor and memory on the IP network device wherein the processor executes executable instructions stored in memory to receive an authorization message from a host provider device, authorizing an end device to communicate through the host provider device, wherein the authorization message includes an authorization refresh timer quantity, modify the authorization refresh timer quantity from a first quantity to a second, smaller quantity, send the authorization message with the modified authorization refresh timer to the end device, receive a register message, hold the register message, and when a network switch event occurs, forward the held register message to the host provider device.
