Digital Terminal Voice Service Registration Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital terminals fail to recover voice services in a timely manner after an upper-layer network fault is resolved, as they wait for a detection time before initiating registration retries, leading to delayed service restoration.
Innovation Solution
A voice service registration method where the digital terminal detects user operations on a voice terminal and directly triggers the registration process upon failure, reducing the need for passive waiting and enabling immediate service recovery by sending registration packets through intermediate network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the digital terminal waits for a detection time before initiating registration retry, then the system can avoid unnecessary registration attempts during network faults, but the voice service cannot be recovered in time after the network is restored
Solution Approach 1:
The digital terminal performs voice service registration in advance before the network fault occurs, or immediately when the fault is detected, rather than waiting for a predetermined detection time. This preliminary action ensures that when the network is restored, the registration can proceed immediately without delay, resolving the contradiction between avoiding unnecessary attempts and enabling timely recovery.
2Reliability
If the digital terminal performs multiple registration retries with increasing wait times, then the system can handle persistent network faults, but the service recovery is delayed when the network is restored during the waiting period
Solution Approach 1:
The digital terminal implements a feedback mechanism where the registration retry behavior is dynamically adjusted based on network status detection. When the network is detected to be restored during a waiting period, the terminal immediately initiates registration retry rather than continuing to wait. This feedback-driven approach maintains fault tolerance while enabling rapid service restoration when conditions improve.

AI summary
Embodiments of the present invention relate to the communications field, and disclose a voice service registration method and a digital terminal, to resolve a problem that a voice service cannot be recovered in time after an upper-layer network of a digital terminal is recovered from a fault. A specific solution is: after a digital terminal re-registers a voice service for the nth time, detecting, by the digital terminal, that a user performs a first operation on a voice terminal connected to the digital terminal, where n is an integer greater than or equal to 1; and triggering, by the digital terminal, a voice service registration process when detecting that registration of the voice service fails. The present invention is applied to a voice service registration process.
