Service Continuity in Centralized Network Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In centralized service network systems, especially in scenarios of terminal mobility between different switching entities, conventional procedures fail to ensure correct and continuous registration of contact points for centralized services, leading to service continuity issues during re-routing situations.
Innovation Solution
A method involving the detection of deregistration requests and the initiation of a waiting timer before re-registering a terminal with a second switching entity, ensuring continuous registration and service continuity by preventing premature deregistration and facilitating seamless re-routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional deregistration procedures are used in centralized service network systems, then switching entities can be deregistered from terminal contacts, but service continuity is lost during terminal mobility between switching entities
Solution Approach 1:
The system performs preliminary actions by starting a waiting timer upon detecting a deregistration request, before the actual deregistration occurs. This allows the system to anticipate and prepare for the upcoming deregistration event, enabling it to intercept and handle subsequent registration requests from new switching entities in a timely manner, thus maintaining service continuity without complex additional mechanisms
Solution Approach 2:
The waiting timer acts as an intermediary mechanism between the deregistration request and the actual deregistration execution. It creates a buffer period during which the system can still process and respond to registration requests from new switching entities, effectively mediating the transition between old and new contacts while preserving service continuity
2Measurement precision
If waiting timer mechanism is introduced to maintain service continuity, then registration accuracy is improved during terminal mobility, but processing time increases
Solution Approach 1:
The system applies partial action by introducing a waiting timer that operates only during terminal mobility scenarios when deregistration requests are detected, rather than continuously. This selective application maintains registration accuracy when needed while avoiding unnecessary time delays during normal operations, thus balancing precision with efficiency

AI summary
There are provided measures for enabling/realizing service continuity in a centralized service network system. Such measures exemplarily comprise detecting a deregistration request for deregistering a terminal with respect to a first switching entity from a registration in which the first switching entity is registered for the terminal as a contact point for centralized services, starting a waiting timer for waiting for a registration request for registering the terminal with respect to a second switching entity upon detection of said deregistration request, and re-registering the terminal in the registration such that the second switching entity is registered for the terminal as a contact point for centralized services upon detection of the registration request for registering the terminal with respect to the second switching entity before expiry of the waiting timer.
